Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording and / or reproducing apparatus for a disk-shaped recording medium such as an optical disk or a magneto-optical disk, and in particular, it extracts desired information from one or a plurality of disk-shaped recording media. The present invention relates to a recording and / or reproducing device that forms a group by reproducing information of this group.

[0002]

2. Description of the Related Art Generally, a reproducing apparatus which takes out one optical disk from a storage unit in which a large number of disc-shaped recording media, for example, read-only optical disks are stored, and which reproduces an information signal from the taken-out optical disk is known. A storage unit that stores a large number of optical discs and a reproduction unit that reproduces an information signal from one optical disc selected from the plurality of optical discs stored in the storage unit.

This reproducing unit has a mounting portion on which one selected optical disc is mounted, and rotation driving means for rotating the optical disc mounted on the mounting portion, and a radial direction of the optical disc. It has a recording and / or reproducing means that is movable and records and / or reproduces an information signal on the optical disc.

Further, this reproducing apparatus is selected from a large number of optical disks housed in the housing unit.
A loading mechanism that conveys one optical disk to a mounting position corresponding to the mounting portion of the rotation driving means in the recording and / or reproducing unit, and the optical disk transported by the loading mechanism is mounted by the rotation driving means. And a chucking mechanism to be attached to the section.

The selection of the optical disk is performed by transporting an arbitrary optical disk from a large number of optical disks in the storage unit to a predetermined position (loading position) corresponding to the loading mechanism. The loading mechanism transports the optical disc transported to the loading position to the mounting position.

Normally, when managing a large number of optical disks, instead of directly managing by the number of the optical disk (product number etc.), it is convenient to use a groove for accommodating the optical disk provided in the storage unit. A serial number is given and the serial number is defined as an optical disk number (disk number) to manage the optical disk.

Then, for example, when reproducing an optical disk with a reproducing apparatus, the number input key such as a ten key on the operation panel is operated to input the disk number, and the input disk number corresponds to the input disk number. It is designed to play optical discs.

Further, a memo such as a title of the disc is registered in accordance with each disc number by using a character key or the like, and when the disc number is inputted at the time of reproduction, the disc number and a memo corresponding to the disc number are displayed on the display panel. It is displayed to improve operability.

[0009]

However, in the above-mentioned conventional reproducing apparatus, when inputting the disc number, the keys such as the ten keys are arranged so that the disc number is input. When registering the corresponding memo, the following problems occurred. In other words, the memo registration is
Normally, after inputting the disc number, the memo corresponding to the disc number is input using character keys, etc.,
Each time the disc number is input, it is necessary to operate the key of the number that matches the number. For example, when a large number (for example, 50 or more) of optical discs are stored in the storage unit, the disc number is input. There is a problem in that the numeric keypad must be selected and operated a plurality of times each time, which greatly increases the operating procedure.

Also, in the case of retrieving a disk number or the like, a method of performing a toggle operation by using a specific operation key is adopted, and if there are many registered disk numbers, the retrieval becomes very troublesome. There is a problem.

Further, the reproducing apparatus capable of reproducing a large number of optical disks does not employ a structure in which the operator directly operates the optical disks to perform reproduction, and the order of the optical disks to be reproduced can be arbitrarily set in advance. Since the setting is made, it is necessary to know what the optical disk to be reproduced (played) next is, in order to improve operability and convenience. However, in the conventional reproducing apparatus, since the disc number displayed on the display panel is only the disc number corresponding to the optical disc currently being reproduced, it is not known what is reproduced (played) next. ,
There was a problem that the order had to be confirmed by key operation.

Further, when only a desired song is selected from one optical disc or a plurality of optical discs to form a group, conventionally, a desired optical disc is selected by the ten keys or the like called a program, and then the selection is performed. Since a desired music piece is selected from the optical disk, it is necessary to provide a plurality of keys for selecting the above-mentioned optical disk and music piece, and this selection operation also causes a troublesome complication.

Further, the above program has a problem that it is not convenient when the reproduction of the music set at the time of reproduction is completed, it is necessary to newly set at the time of the next reproduction.

The present invention has been made in view of the above problems, and it is possible to form a group in which only desired songs are collected and to reproduce the songs of the group by a simple operation.
The keys for forming and reproducing the group can be simplified to reduce the area of the operation panel and reduce the cost, and prevent the inconvenience of resetting the group once set at the time of the next reproduction. It is an object of the present invention to provide a recording and / or reproducing apparatus that enables the user to know not only the currently reproduced song but also the song to be reproduced next.

The mechanism of such a disk-shaped recording medium reproducing apparatus is driven by rotating the rotary table 1 clockwise and counterclockwise as shown in FIG. 3, and is selected by various keys of the operation panel 11, for example. And a rotation drive mechanism 41 for rotating and transporting the optical disc D to a predetermined position (loading position A), and a loading mechanism for taking out the optical disc D which is rotationally transported to the loading position A from the slit 4 and transporting it to a mounting position B of a reproducing unit described later. 42
And the optical disc D transported by the loading mechanism 42
A reproduction unit 43 that reproduces an information signal and a rotation position detection mechanism 44 that detects the rotation position of the rotary table 1.

As shown in FIG. 3, the rotary transport mechanism 41 is composed of a motor 45 installed in, for example, one corner portion of the housing 2 and a speed reduction mechanism 46 by a gear train. One drive gear 47 constituting 46
And the gear portion 7 of the rotary table 1 are always meshed with each other. The motor 45 is driven by the rotation of the motor 45.
The rotating force of the rotating shaft of the motor 45 is transmitted to the speed reducing mechanism 46 via the belt 48, and the rotating force of the rotating shaft of the motor 45 is reduced by the speed reducing mechanism 46, and finally the drive gear 47. It is transmitted to the gear portion 7 of the rotary table 1 via the rotary table 1 to rotate the rotary table 1. The motor 45 is of a type that performs normal rotation and reverse rotation, whereby the rotary table 1
Also rotates clockwise and counterclockwise.

The loading mechanism 42 is installed in a corner portion of the housing 2 which is different from the corner portion in which the rotary drive mechanism 41 is installed. Basically, as shown in FIG. Above the table, the rotary table 1 on the optical disc D at the loading position A
A guide rail 49 that is installed so as to extend obliquely upward from a position facing the center of the optical disc D toward the corner portion, and an outer peripheral surface that is installed below the corner portion and faces the corner portion of the optical disc D at the loading position A. And a transporting means 50 for rotating and transporting the optical disc D to the upper position, that is, the mounting position B of the reproducing unit 43 while supporting the optical disc D at two points.

The guide rail 49 has a curved surface 49a facing the optical disc D, and the curved shape is such that the rising portion is substantially along an arc and is formed to be slightly flat upward. For example, when viewed geometrically, the shape is along the shape of the first quadrant of an ellipse whose major axis is in the horizontal direction. The guide rail 49 supports the central shaft 3 of the rotary table 1 from above, and a metal fixing plate 51 that is installed over the corner portion.
In contrast, it is rotatably attached. For more information,
The guide rail 49 is rotatably mounted around a shaft 52 provided at the lower end thereof.

The transfer means 50 includes first and second arms 54 and 55 having a single support shaft 53 as a common rotation center.
A support shaft 56, which is different from the support shaft 53, is used as a center of rotation, and the first and second arms 54 and 55 are placed at eccentric positions of the support shaft 56.
A pin 59 inserted into the cam grooves 57 and 58 formed in the
And a cam 60 having been planted. The cam 60 is rotationally driven by a motor 61 installed obliquely below the loading position A. Further, a torsion spring 62 is attached to a portion of the common support shaft 53, and the torsion spring 62 has a tip end portion of each of the first and second arms 54 and 55 (a portion provided with a roller described later). ) Is attached so as to urge the closing direction.

The first arm 54, as shown in FIG.
At its upper part, a drive piece 63 extending while curving in a reverse shape in the direction of the rotary table and in the direction of the corner portion of the housing 2, and a substantially L-shaped bend from the center of the lower part of the drive piece 63 in the direction of the rotary table. An operating piece 64 extending in the same direction is formed integrally with a synthetic resin, and the cam groove 57 is formed in a reverse shape along the curve of the driving piece 63 in the substantially central portion of the driving piece 63. It is formed to be curved. A common support shaft 53, which is the center of rotation, is inserted through the right end of the drive piece 63.

The tip portion of the operating piece 64 is positioned so as to be positioned obliquely below the optical disc D at the loading position A in the normal state (a state where the optical disc D at the loading position A is not rotated and conveyed). A roller 65, which is rotatably supported by the operation piece 64, is attached to the tip portion.

Therefore, when the first arm 54 rotates counterclockwise about the support shaft 53, the bottom of the roller 65 contacts the outer peripheral surface of the optical disc D (in particular, the position diagonally lower left in the drawing). When the optical disk D is brought into contact with the optical disk D and further rotated by the first arm 54, the optical disk D is lifted obliquely upward and brought into contact with the facing surface of the guide rail 49. And first
By rotating the arm 54, the optical disc D is rotated and conveyed upward along the facing surface 49a of the guide rail 49.

On the other hand, the lower arm of the second arm 55 has a driving piece 66 that extends while curving in a reverse shape in the direction of the rotary table and in the direction of the corner of the housing 2.
And one side of the upper part of the drive piece 66 (rotary table 1
Side) and a detection piece 67 extending upward while bending in an approximately L-shape from the side) are integrally formed of synthetic resin, and the cam groove 58 is formed substantially in the central portion of the drive piece 66. There is.

In the illustrated example, the cam groove 58 is a portion (first portion 5) having a length ⅓ of the total length from the left end in the drawing.
Up to 8a), it has the same shape as the cam groove 57 in the first arm 54. The lower portion (second portion 58b) from the position of ⅓ toward the right end in the drawing has an arcuate shape having a downward convex portion up to a ½ length thereof,
In addition, it is formed in an arc shape that is continuous with the arc of the first portion 58a and has a remaining half length (the third portion 58a).
c) is linearly formed, and an upper portion (fourth portion 58d) extending from the 1/3 position toward the right end is formed in an arc shape having an upward convex shape.

That is, from the first portion 58a to the second portion 5
The shape up to 8b is the same arcuate shape as the cam groove 57 formed in the first arm 54. Also, these arcs (the arc of the cam groove 57 in the first arm 54 and the first portion 58 of the cam groove 58 in the second arm 55).
The arc from a to the second portion 58b) is an arc whose curvature center is the support shaft 56 of the cam 60, as shown in FIG.

A common support shaft 53, which is the center of rotation, is inserted through the rotary table side end of the drive piece 66 of the second arm 55. When the tip of the detection piece 67 is in a normal state (a state in which the optical disc D at the loading position A is not rotationally conveyed),
It is positioned so as to be positioned diagonally above the optical disc D at the loading position A, and a roller 68 rotatably supported by the detection piece 67 is attached to the tip of this.

Therefore, the second arm 55 is attached to the support shaft 53.
By rotating the roller 68 in the clockwise direction, the bottom portion of the roller 68 comes into contact with the outer peripheral surface of the optical disc D (in particular, the position diagonally upper left in the drawing), and further rotation is prevented. There is.

On the contrary, when the optical disk D is not present at the loading position A, the second arm 55 is rotated in the clockwise direction, and its corner side end 55a.
Will rotate upwards. In the present embodiment, since the optical disc D is not present at the loading position A, the corner side end portion 5 of the second arm 55 is
The detection switch 70 is provided on the locus of rotation of the optical disc 5a, that is, on the locus of rotation when the rotation further advances from the position of rotation inhibition with respect to the second arm 55 when the optical disc D is present. Therefore, this detection switch 7
The contact of 0 is the end 55 on the corner side of the second arm 55.
When pressed by a, for example, the detection switch 70 is turned on, and it can be electrically recognized that the optical disc D does not exist at the loading position A.

Next, the specific operation of this loading mechanism will be described.

First, when the cam 60 rotates clockwise around the support shaft 56 from the normal state shown in FIGS. 3 and 6, in the initial stage, as shown in FIG. 7, the pin 59 of the cam 60 moves to the first position. The upper surface of the cam groove 57 in the first arm 54 and the first portion 5 of the cam groove 58 in the second arm 55.
Since the upper surface extending from 8a to the second portion 58b is pushed upward, the first and second arms 54 and 55 rotate clockwise about the common support shaft 53 in the drawing, and the cam is rotated. As the rotation of 60 advances, the tip portion (roller 68) of the second arm 55 moves to the loading position A.
The optical disc D located at is approached. Then, the tip portion 68 of the second arm 55 comes into contact with the optical disc D, whereby the clockwise rotation of the second arm 55 is stopped. At this time, the corner-side end 55 a of the second arm 55 is at a position sufficiently distant from the detection switch 70.

Then, when the cam 60 further rotates in the clockwise direction, the pin 59 of the cam 60 pushes the upper surface of the cam groove 57 of the first arm 54 upward as shown in FIG. For the second arm 55, the second
Since the tip end portion 68 of the arm 55 contacts the optical disc D, and the pin 59 of the cam 60 rotates along the upper surface of the fourth portion 58d of the cam groove 58, only the first arm 54 is provided. Will rotate clockwise about the common support shaft 53.

When there is no optical disk at the loading position A, there is no means for restricting the rotation of the second arm 55 as shown in FIG. 14, so that the torsion spring 62 biases the second arm 55. Rotates clockwise until the lower surface of the second portion 58b of the cam groove 58 comes into contact with the pin 59 of the cam 60, and accordingly, the corner-side end 55a of the second arm 55 moves. It is rotated upward and the detection switch 70 is turned on.

Next, when the cam 60 further rotates in the clockwise direction from the state shown in FIG. 8, the pin 59 of the cam 60 moves the cam groove 5 in the first arm 54 this time, as shown in FIG.
Since the lower surface of 7 is pushed downward, the first arm 54 rotates counterclockwise about the common support shaft 53, and as the rotation of the cam 60 progresses, No. 1 arm 54 tip portion (roller 65)
Will approach the optical disc D at the loading position A. Also in this case, with respect to the second arm 55, the tip portion 68 of the second arm 55 is in contact with the optical disc D, and the pin 59 of the cam 60 is in the cam groove 58.
The second arm 55 remains stationary as it moves rotationally along the upper surface of the fourth portion 58d of the.

Next, when the cam 60 further rotates in the clockwise direction, the pin 59 of the cam 60 moves to the first position as shown in FIG.
Since the lower surface of the cam groove 57 in the arm 54 is pushed further downward, the tip end portion 65 of the first arm 54 contacts the optical disc D, and the tip end of the first arm 54 as the rotation of the cam 60 progresses. The portion 65 pushes up the optical disc D toward the curved surface 49a of the guide rail 49. At this time, the second arm 55 also rotates counterclockwise about the common support shaft 53 as the optical disc D moves obliquely upward.

Next, when the cam 60 further rotates in the clockwise direction, as shown in FIGS. 11 and 12, the pin 5 of the cam 60 is rotated.
9 pushes the lower surface of the cam groove 57 of the first arm 54 further downward, so that the optical disc D
First contacts the curved surface 49a of the guide rail 49. As the rotation of the cam 60 progresses further, the first arm 54 pushes the optical disc D upward and diagonally to the upper right in the drawing, so that the optical disc D moves along the curved surface 49a of the guide rail 49 in the drawing. It will be rotated and conveyed diagonally upward to the left.

At this time, for the second arm 55,
The pin 59 of the cam 60 is connected to the third portion 58c of the cam groove 58.
The second arm 55 rotates counterclockwise to a position slightly separated from the optical disc D because the lower surface of the second arm 55 is pushed downward while following the. As a result, in the drawing of the second arm 55 with respect to the optical disc D,
Since the pressing force in the obliquely lower right direction (the pressing force generated by the urging of the torsion spring 62) ceases to act, the optical disc D is smoothly rotated and conveyed along the curved surface 49a of the guide rail 49.

Then, when the cam 60 further rotates in the clockwise direction, the pin 59 of the cam 60 moves to the second position as shown in FIG.
When the lower surface of the third portion 58c of the cam groove 58 in the arm 55 is pushed downward, the arm 59 is rotated and moved along the third portion 58c, and when the cam 60 further rotates, the pin 59 moves to the third portion. 58c to the second part 5
Rotate toward 8b. Pin 59 is just the third
When reaching the boundary between the second portion 58b and the second portion 58c, the optical disc D reaches the mounting position B, and the first and second
2 at each tip 65 and 68 of each arm 54 and 55 of
It will be supported by points.

At this time, the cam groove 57 of the first arm 54 and the first and second portions 58a and 58b of the cam groove 58 of the second arm 55 are aligned with each other, and the cam 6
The pin 59 of 0 is rotated and moved in the portion where the cam grooves match. In this case, since the center of curvature of the arc in the overlapped portion is the same as that of the support shaft 56 of the cam 60, the optical disc D stops at the mounting position B even if the pin 59 stops at any position of the overlapped portion. Maintain the condition.

As described above, in the loading mechanism 42, the cam 6 rotated by the rotational driving of the motor 61 is used.
0 is provided with a pin 59, and the pin 59 is configured to penetrate the respective cam grooves 57 and 58 of the first and second arms 54 and 55.
And the second arms 54 and 55 can be rotated simultaneously, and the change in the shape of the cam grooves 57 and 58, in particular,
The first portion 58 of the cam groove 58 in the second arm 55
It is possible to change the distance C between the tips of the first and second arms 54 and 55 (rollers 65 and 68) during the rotation of the arms 54 and 55 by changing the shape from a to the third portion 58c. Becomes

This is because the optical disc D placed at the loading position A by the clockwise rotation of the cam 60 is kicked up by the counterclockwise rotation of the arms 54 and 55, and the curved surface 49a of the guide rail 49 and both sides. Arms 54 and 5
The optical disc D is regulated by the tip portions 65 and 68 of the optical disc 5.
The leading ends 65 and 68 of the arms 54 and 55 follow the transport path of the optical disc D when the playback unit 43 is transported to the mounting position B. That is, the trajectory of the optical disc D can be freely changed by setting the guide rail 49.

Therefore, the tips 6 of the arms 54 and 55 are
In contrast to the complete circular arc-shaped conveyance trajectory D when the distance C of 5 and 68 is fixed, an elliptical conveyance trajectory E that is low in the height direction
Therefore, a space-saving mechanism can be realized. The rotation angle of the cam 60 is determined by the rib 71 and the two-position switch 72, and is 360 ° in this example.

Further, as can be seen from the operation shown in FIGS. 6 to 14, the rotation direction of each arm 54 and 55 at the initial stage depends on the shape of the cam groove 57 of the first arm 54 and the pin 59 of the cam 60. Is rotated in the clockwise direction until is positioned vertically above the support shaft 56. At this time, the second arm 5
The tip portion 68 of the optical disc 5 contacts the outer circumference of the optical disc D at the loading position A, but if the optical disc D is not present at the loading position A, then the second arm 55 is used.
Is rotated further clockwise, and its corner side end 55
At a, the detection switch 70 is turned on, for example.

That is, the shape of the cam groove 58 of the second arm 55 makes it possible to detect the optical disc D at an early stage, which is the initial stage after the rotational driving of the arms 54 and 55 is started. Further, the cam groove 5 of the first arm 54
7 and the center of curvature of the arc from the first portion 58a to the second portion 58b of the cam groove 58 of the second arm 55 are the same as the center of rotation of the cam 60 (the support shaft 56). There is a margin in the stop angle of the cam 60 at the mounting position B of D.

This is because the pin 59 has an arc portion of the cam groove 57 in the first arm 54 and the first portion 58a to the second portion 58b of the cam groove 58 in the second arm 55.
The position of the optical disc D conveyed to the mounting position B of the reproducing unit 43 does not change even if the optical disc D is stopped at any position where the circular arc portion and the overlapping portion of the optical disc D overlap. Can be realized.

The loading mechanism 4 of this reproducing apparatus
A stopper mechanism 73 is provided at a position corresponding to 2. The stopper mechanism 73 has a stopper piece 75 rotatably mounted around a support shaft 74 provided on the lower plate 2 a of the housing 2. The stopper piece 75 has a shape in which the upper portion thereof extends in the rotary table direction and the corner portion direction of the housing 2, and a tension spring 76 is attached from the lower end of the stopper piece 75 on the rotary table side to the lower plate 2a of the housing 2. Has been. Therefore, the stopper piece 75 is always kept by the spring 76 by the support shaft 7
It is urged to rotate clockwise around 4.

Further, the stopper piece 75 has a restricting portion 77 formed in a tapered shape toward the upper side at the end portion on the corner side thereof, and the restricting portion 77 abuts against the pin 59 of the cam 60. By the contact, the clockwise rotation of the stopper piece 75 is restricted. Also, the stopper piece 75
Has a stopper pin 78 projecting upward at the upper end on the rotary table side.

When the pin 59 of the cam 60 rotates clockwise with the loading operation of the loading mechanism 42, the stopper piece 75 also rotates clockwise about the support shaft 74. At this time, the stopper pin 78 provided on the upper end of the stopper piece 75 on the rotary table side is provided in the concave portion 8 at the position corresponding to the loading position A among the large number of concave portions 8 provided on the outer periphery of the rotary table 1. Mating. The rotation of the rotary table 1 is restricted by fitting the stopper pin 78 into the recess 8. Therefore, the stopper mechanism 73 constitutes a protection mechanism during reproduction of the optical disc D and during loading of the optical disc D.

In this example, the opening width L of each recess 8 is set to be slightly larger than the diameter of the stopper pin 78. Therefore, even if some error occurs in the stop angle of the rotary table 1, the optical disc D can be corrected to the regular loading position A.

Next, as shown in FIG. 17, the reproducing unit 43 includes a turntable 81 on which the optical disc D is mounted.

The swing plate 87 is provided with holes at three positions, and the support plate 84 is integrally formed with a projection 88 protruding upward at a position corresponding to the hole and inserted into the hole. The floating means 86 is composed of a spring 89 inserted between the protrusion 88 and a damper 90 provided around the swing plate 87 so as to surround the hole between the swing plate 87 and the support plate 84. . The floating means 86 are provided at three locations corresponding to the protrusions 88.

Further, the swing plate 87 is provided with insertion holes 91 (three places) in the vicinity of the installation positions of the respective floating means 86. Further, the support plate 84 is integrally formed with a lock pin 92 which is selectively inserted into the insertion hole 91 at a position corresponding to each insertion hole 91 of the swing plate 87. The diameter of the tip of the lock pin 92 is slightly smaller, and the diameter of the insertion hole 91 of the swing plate 87 is set to be substantially the same as the diameter of the tip of the lock pin 92. There is. Therefore, the tip of the lock pin 92 is
When inserted into the insertion hole 91 of the rocking plate 87, the rocking plate 87
The peripheral portion of the insertion hole contacts the upper surface of the large diameter portion of the lock pin 92 to prevent the swing plate 87 from moving further downward.

In this reproducing apparatus, the lock means 93 for restricting the elastic force of the floating means 86 is provided. The lock means 93 has a lock lever 94 above the swing plate 87 and extending in the width direction of the swing plate 87. This lock lever 94

It is rotatably attached via. A first mounting member 96 is fixed to the other end of the lock lever 94 on the upper left side in the drawing, and the rocking plate 87 is mounted on the lower surface of the support plate 84. Member 9
The second mounting member 97 is fixed to a position corresponding to 6. A tension spring 98 is attached between the attachment members 96 and 97.

Therefore, in the natural state, the lock lever 94 is urged to rotate downward by the tension spring 98 mounted between the mounting members 96 and 97, whereby the lock lever 94 swings. Moving plate 87
Will be pressed downwards. Therefore, the swing plate 87 is
The damper 90 and the spring 89 are urged in the direction of approaching the support plate 84 against the elastic force of the damper 90, and are integrated (fixed) with the support plate 84. At this time, as already described above, the tip end portion of the lock pin 92 arranged on the support plate 84 is inserted into the insertion hole 91 of the swing plate 87, and the peripheral portion of the insertion hole of the swing plate 87 is the lock pin 92. The oscillating plate 87 and the supporting plate 84 are brought into contact with the upper surface of the large-diameter portion to be integrated (fixed) while maintaining a constant separation width.

Further, the lock lever 94 is integrally provided at its other end with a tongue piece 98 extending downward. A pin 10 that projects laterally and is inserted into a curved hole 100 of a slider 99, which will be described later, is provided under the tongue piece 98.

Each gear that constitutes the reduction mechanism 104 is rotatably attached to the fixed plate 51 via a support shaft.

Then, the rotational force of the rotary shaft of the motor 103 due to the rotational driving of the motor 103 is transmitted to the speed reduction mechanism 104 via the belt 105, whereby the speed reduction mechanism 1
The rotational force is transmitted to the final gear (hereinafter, referred to as main gear) 106 of No. 04. The motor 1
Reference numeral 03 denotes a type that performs normal rotation and reverse rotation, whereby the main gear 106 also rotates clockwise and counterclockwise. A spiral groove 107 is provided on the surface of the main gear 106 facing the reproducing unit 43, and a pin 108 protruding from the slider 99 to the main gear 106 side is inserted into the spiral groove 107. There is. Therefore, as the main gear 106 rotates clockwise and counterclockwise, the slider 99 moves vertically.

The slider 99 has a shape in which a metal plate is processed into a U-shaped cross section, and a pair of projecting pieces 99a and 99b projecting toward the reproducing unit 43 side are integrally formed on the upper portion thereof.

Is moved downward by driving the vertical movement mechanism 102, so that the other end of the lock lever 94 (end on the slider 99 side) is rotationally moved downward. As a result, the lock lever 94 presses the swing plate 87 downward to fix the swing plate 87 and the support plate 84, and the support plate 84 is rotated as the lock lever 94 rotates.
The end of the vertical movement mechanism 102 on the side of the vertical movement mechanism rotates and moves downward about the support shaft 85.

When the pin 108 of the slider 99 reaches the bottom dead center of the spiral groove 107, the downward movement of the slider 99 is stopped, and the swing plate 87 is integrated with the support plate 84. And, the state is inclined by an angle θ with respect to the horizontal line. Therefore, the housing 83 (in which the spindle motor and the optical pickup 82 are incorporated) provided so as to hang down from the swing plate 87 is also inclined by an angle θ with respect to the vertical line, and the housing is The turntable 81 of the spindle motor in 83 is separated from the optical disc D at the mounting position B.

On the contrary, the slider 99 has the vertical movement mechanism 1
When it is moved upward by 02, this time, the end portion of the lock lever 94 on the slider 99 side is rotated and moved upward. As a result, the downward pressing of the rocking plate 87 by the lock lever 94 is released, the rocking plate 87 is elastically supported by the support plate 84 through the floating means 86, and the lock lever 94 rotates. Along with
The end portion of the support plate 84 on the side of the vertical movement mechanism 102 is rotated and moved upward with the support shaft 85 as the center.

Then, when the pin 108 of the slider 99 reaches the top dead center of the spiral groove 107, the upward movement of the slider 99 is stopped, and the swing plate 87 is elastically attached to the support plate 84 by the floating means 86. In the supported state, the plate surface is supported so as to be along the horizontal direction. Therefore, the box 83 provided on the rocking plate 87 also hangs down along the vertical line, and the turntable 81 of the spindle motor in the box 83 has the center hole of the optical disc D at the mounting position B. It will be in the state of being inserted into.

A slider 99 is attached to the fixed plate 51.
The chucking mechanism 111 is installed at a position closer to the rotary table 1 than the arrangement position. The chucking mechanism 111 has a support shaft 112 attached to the fixed plate 51 at the top.
A holder 113 that is rotatably supported through the holder 113 and is supported so as to hang down, and a lower portion of the holder 113, that is, a hole 114 provided at a position facing the turntable 81 of the spindle motor in the reproducing unit 43. It is composed of a chucking member 115 with a magnet fitted therein.

The hole 114 provided in the holder 113
Has a hook hole shape in which the opening width is continuously reduced toward the bottom, and the thickness thereof is continuously increased toward the bottom. On the other hand, the chucking member 115 is composed of a cylindrical bobbin having flanges formed on both end surfaces thereof and a ring-shaped magnet fitted inside the bobbin. The chucking member 115 has an opening on its surface facing the turntable 81 of the bobbin,
The internal magnet faces the turntable 81.

The hole 1 provided in the holder 113
The thickness of the thick portion 113a on the lower inner peripheral surface of 14 is set to be substantially the same as the height between the flanges of the bobbin.
Therefore, when the bobbin of the chucking member 115 is fitted into the hole 114, the thick portion 113a is located between the flanges of the bobbin, and there is a slight play between the flanges and the thick portion 113a. Also, the chucking member 115 does not fall out of the hole 114.

The holder 113 is integrally formed with a guide piece 121 bent downward in a V shape on the side surface of the corner portion toward the reproducing unit 43 side. In addition, the pair of protrusions 99a and 99b of the slider 99 are
The pin 122 protruding toward the chucking mechanism 111 is integrally formed on the protrusion 99b on the chucking mechanism 111 side. The lower end of the holder 113 is constantly urged by an unillustrated known elastic means (spring or the like) so as to be rotatably moved to the reproduction unit 43 side. Piece 1
21 is always in contact with the pin 122 of the slider 99.

Therefore, when the slider 99 is located at the bottom dead center, the pin 122 presses the guide piece 121 of the holder 113 in the direction away from the reproducing unit 43 against the bias of the elastic means (not shown). The holder 113 is in a state of being inclined with respect to the vertical line (a state of being separated from the reproducing unit 43). When the slider 99 is moved upward by the vertical movement mechanism 102, for example, the pin 12 is moved.
Since the pressing by 2 is gradually released with the upward movement, the holder 113 is rotationally moved in the direction in which the holder 113 gradually approaches the reproducing unit 43 by the elastic means (not shown). At this time, the pin 122 moves upward while contacting the guide piece 121.

Also, the holder 113 has
A tongue piece 123 extending downward is integrally formed, and a stopper piece (not shown) is provided on the fixed plate 51 at a position facing the tongue piece 123 by, for example, cutting and raising. Therefore, as the slider 99 moves upward, the pressing of the guide piece 121 by the pin 122 is gradually released, and the holder 113 is pressed toward the reproducing unit 43 side by the elastic means (not shown). At this time, the tongue piece 123 of the holder 113 comes into contact with a stopper piece (not shown) of the fixed plate 51, and as a result, the holder 113 is held in a state along the vertical line.

In this state, as already described above, the turntable 8 in the spindle motor of the reproducing unit 43 is inserted into the center hole of the optical disc D at the mounting position B.
Since 1 is in the inserted state, the tip portion (made of metal) of the turntable 81 is attracted to the magnet of the chucking member 115, and the optical disc D becomes the turntable 81 in the state along the vertical direction. It is in the form of being sandwiched by the chucking member 115. That is, the optical disc D is vertically clamped.

Thereafter, the lock lever 94 moves the slider 9
9 continues to rotate by the upward movement of 9, but the end surface of the support plate 84 on the corner portion side abuts the pin 124 provided on the fixed plate 51, so that the support plate 84 keeps its plate surface direction horizontal. It will remain dripping. At this time, the swing plate 87
Rises due to the elastic force of the spring 89 of the floating means 86. That is, the reproducing unit 43 moves up by the action of the spring 89 while maintaining the posture in which the optical disc D is vertically clamped.

A lever 113b, which extends horizontally toward the center of the rotary table 1 and has its tip end rotatably supported by the fixed plate 51 about the support shaft 204, is provided above the holder 113. The lever 113b is integrally provided with a long hole 125 having a horizontal major axis in its central portion. Then, in the long hole 125, the pin 1 provided so as to project to the holder 113 side above the guide rail 49.
26 is inserted. Therefore, the holder 11
The guide rail 49 rotates about the support shaft 52 and the upper portion thereof rotates and moves in the direction away from the optical disc D in the process in which the guide rail 49 is suspended in the vertical direction by the upward movement of the slider 99. Become.

That is, the upward movement of the slide 99 causes the reproducing unit 43, the chucking member 115, and the optical disc D to move upward. In this process, the guide rail 49 moves the optical disc D being raised. On the other hand, it is possible to escape upward while keeping a certain distance, and it is possible to prevent the optical disc D from colliding with the guide rail 49 in advance.

Then, when the slider 99 moves further upward, the lock lever 94 is separated from the swing plate 87, whereby the restriction of the elastic force of the lock lever 94 on the floating means 86 is completely released, and the optical disc. The chucking of D to the reproduction unit 43 is completed.

Then, a drive current is supplied to the spindle motor of the reproducing unit 43 to rotationally drive the optical disc D in one direction, and in this state, the optical pickup 82 is moved in the radial direction of the optical disc D, whereby the optical disc D is moved.
The pit information recorded in can be reproduced.

As described above, in this embodiment, since the lock means 93 for selectively restricting the elastic force of the floating means 86 is provided, the following advantages can be obtained. That is, usually, the floating means 86 has a structure in which its vibration path is mainly blocked by rubber or spring so that unnecessary vibration is not propagated to the optical pickup 82 which reads the pit information of the optical disc D as an electric signal. At present, it is a common mechanism.

However, from the viewpoint of accuracy, the swing plate 8
7 swings by the floating means 86,
The center hole of the optical disc D at the mounting position B is the turntable 8 of the spindle motor in the reproducing unit 43.
It has a drawback that it is very unstable and difficult to position with respect to 1. However, in this embodiment, as can be seen from the above-described operation, in the process of chucking the optical disc D to the reproducing unit 43, the elastic force of the floating means 86 is regulated by the lock means 93, so that the optical disc D swings. Since the plate 87 and the support plate 84 are fixed to each other, the rotational movement locus T of the box 83 during chucking can be made highly accurate, and the highly reliable chucking of the optical disc D can be performed. Can be realized.

When the reproduction of the pit information on the optical disc D is completed and the optical disc D is returned to the original position (slit 4), first, the slider 99 is moved downward by the vertical movement mechanism 102 to move it downward. Position it at the dead point. As a result, the chucking of the optical disc D is released, and the optical disc D at the mounting position B has the first and second arms 54 and 55 of the loading mechanism 42.
Only the two points are supported by the tip portions (rollers 65 and 68) of the. Then, the cam 60 of the loading mechanism 42 is rotated in the reverse direction (counterclockwise in the drawing) by the motor 61, so that the optical disc D has the tip portions 65 and 68 of the respective first and second arms 54 and 55.
While being supported at two points, the original position (inside the slit 4 at the loading position A) is returned.

Next, the rotation position detecting mechanism 44 is installed corresponding to the rotation detecting member 131 fixed to the lower surface of the cylindrical supporting member 5 provided in the lower portion of the rotary table 1 and the loading position A. It is composed of a light detection unit 132.

The rotation detector 131 is provided with the first and second concentric circles of the support member 5 having different diameters.
It is composed of ring-shaped detection plates 133a and 133b. The first detection plate 133a is connected to the second detection plate 133b.
The diameter is larger than that of the above, and unevenness is formed on the lower end surface thereof at a constant pitch in the circumferential direction. That is, in the present embodiment, 10 formed on the rotary table 1
Unevenness is formed at a pitch corresponding to 0 slits. Therefore, in this example, among the unevenness, for example, the convex 134
This means that 100 parts are formed.

On the other hand, the second detection plate 133b has the above-mentioned first
Of the detection plate 133a, and the lower end surface of the detection plate 133a has irregularities arranged at different pitches in the circumferential direction. That is, in this embodiment, first, as shown in FIG.
In, for example, the slit 4 corresponding to the point (home position) indicated by the arrow A is defined as the first slit, and the disc number of the optical disc D inserted into this slit 4 is defined as "1". Then, the disk number is sequentially updated + along the direction indicated by the arrow B, and the disk number immediately before the disk number "1" becomes "100".

In such a setting relationship, first, the second detecting plate 133b has no convex at the position corresponding to the disc number "1", and the position corresponding to the disc number "11" is one end face, A protrusion having a position corresponding to the number "12" as the other end face (a protrusion having a pitch length of one in the arrangement pitch of the slits 4) is formed, and a position corresponding to the disc number "21" is set at one end. A protrusion (a protrusion having a pitch length equal to two of the above arrangement pitches) is formed as an end face and a position corresponding to the disc number “23” is the other end face, and a position corresponding to the disc number “31” is formed. A convex (a convex having a pitch length corresponding to three of the arrangement pitches) having one end face and the other end face at a position corresponding to the disc number "34" is formed. By number 1 Convex respectively set only one array pitch longer formed for each, Generally described, the disk ID "10n + 1 (n = 1,2,3 ···
9) ”is one end face and the other end face is the position corresponding to the disk number“ 11n + 1 ”. A protrusion (a protrusion having a pitch length of n in the slit arrangement pitch) is formed. ing.

Further, the light detecting section 132 has three light sensors (first, second and third light sensors). Each optical sensor is composed of a set of a light emitting element and a light receiving element, and the first and second optical sensors are installed at a predetermined interval with respect to the first detection plate 133a. 2 detection plates 1
For 33b, a third optical sensor is installed.
These optical sensors have corresponding detection plates 133a and 133a.
When a convex portion of b is detected, for example, a high-level detection signal is set to be output.

That is, as shown in FIG. 19, these optical sensors are the first and the second inserted between the controller 141 for performing various calculations and controls based on various signals and the ground GND.
And third detection switches SW1, SW2 and SW3. Then, the detection switches SW1, SW2, and SW3 are turned on, for example, every time a convex portion is detected, and the controller 141 has the switches SW1, SW2, and S.
A current change based on the turning on of W3 is supplied as a detection signal.

The controller 141 supplies a drive signal and a deceleration request signal to the drive control circuit 142 based on a rotation request for the rotary table 1 (selection of the optical disc D, etc.). In terms of timing, when the rotary table 1 is rotated by a certain rotation angle, for example, 40 pitches when converted by the array pitch of the slits 4, this drive signal rises based on the above rotation request, and from each optical sensor. Is a pulse signal that falls when 40 pitches are counted based on the detection signal of 1., the deceleration request signal rises from the time of the remaining 10 pitches, and when 40 pitches are counted, like the drive signal. It is a pulse signal that falls to.

The drive control circuit 142 supplies the drive current of a constant level to the motor 45 from the drive control circuit 142 during the period when only the drive signal is supplied to the drive control circuit, and the deceleration is performed. The level of the drive current supplied to the motor 45 is continuously reduced at the stage when the request signal is supplied, and the drive current level becomes zero at the stage where 40 pitches are counted in the above example. The circuit is configured. When the rotation angle is less than 10 pitches, the drive signal and the deceleration request signal rise at the same time.

Next, an example in which the stop control of the rotary table 1 is performed based on the detection signals from the first to third optical sensors will be described with reference to the signal waveform diagrams of FIGS.

First, the rotary table 1 is replaced by the motor 4
By rotationally driving the drive gear 47 by means of FIG.
When the optical sensor is rotated in the direction of arrow C in FIG.
~ The detection signal waveform shown in Fig. 22 is output. Here, the waveform of the detection signal S1 from the first optical sensor and the waveform of the detection signal S2 from the second optical sensor have a phase difference according to the separation width of each optical sensor.

Further, in this embodiment, the first and second
The period in which the detection signals S1 and S2 from the optical sensor are both at a high level indicates the stop position of the optical disc D. For example, the optical disc D with the disc number "7"
When it is desired to stop at the loading position A, the rotary table 1 is stopped when both the first and second optical sensors detect the seventh protrusion. Therefore, in this example, the separation width regarding the installation of the respective sensors is set so that the detection signals S1 and S2 (for example, high level period) from the first and second optical sensors partially overlap. There is.

Then, the detection signal S from the third optical sensor
When the number of pulse signals formed by the logical product of the detection signals S1 and S2 from the first and second photosensors is 1 in the period in which 3 is at a high level, when the falling edge of the detection signal S3 is detected Therefore, the optical disc D corresponding to the disc number "12" is located at the loading position A, and each detection from the first and second optical sensors is performed during the high level period of the detection signal S3. When the number of pulse signals formed by the logical product of the signals S1 and S2 is two, the disc number “23” is set at the loading position A at the time when the falling edge of the detection signal S3 is detected.
Thus, the optical disc D corresponding to is located.

Thus, the rotary table 1 is shown in FIG.
The number of pulse signals formed by the logical product of the detection signals S1 and S2 from the first and second photosensors during the period when the detection signal S3 is at a high level when rotating in the direction of arrow C in FIG. Is m (m = 1, 2, 3 ...
In the case of 9), when the falling edge of the detection signal S3 is detected, the disc number “11m +
The optical disc D corresponding to "1" is located.

When the rotary table 1 is rotating in the direction of arrow C in FIG. 4, the detection signal S3
However, this time, in the low level period, when the number of pulse signals formed by the logical product of the detection signals S1 and S2 from the first and second photosensors is 9, the rising edge of the detection signal S3 is detected. At this time, the optical disc corresponding to the disc number “21” is located at the loading position A, and during the period when the detection signal S3 is at the low level, the optical signals from the first and second optical sensors are detected. When the number of pulse signals formed by the logical product of the detection signals S1 and S2 is eight, the optical disc D corresponding to the disc number “31” is located at the loading position A when the falling edge of the detection signal S3 is detected. Will be.

Thus, the rotary table 1 is shown in FIG.
The number of pulse signals formed by the logical product of the detection signals S1 and S2 from the first and second photosensors while the detection signal S3 is at a low level when rotating in the direction of arrow C in FIG. Is m (m = 9,8,7 ...
.. 2), when the rising edge of the detection signal S3 is detected, the disc number "10 (1
The optical disc D corresponding to "1-m) +1" is located.

In this case, exceptionally, when the number of pulse signals formed by the logical product of the detection signals S1 and S2 from the first and second photosensors is 10 during the period when the detection signal S3 is low level. Actually, there are cases where the number is 11, and in this case, the optical disc D corresponding to the disc number “11” is located at the loading position A when the rising edge of the detection signal S3 is detected. Become.

On the contrary, when the rotary table 1 is rotating in the direction of arrow B in FIG. 4, each detection signal S1 from the first and second photosensors is in the high level period of the detection signal S3. And the number of pulse signals formed by the logical product of S2 is 9, the optical disc D corresponding to the disc number “91” is located at the loading position A at the time when the trailing edge of the detection signal S3 is detected. When the number of pulse signals formed by the logical product of the detection signals S1 and S2 from the first and second photosensors is eight during the period when the detection signal S3 is at the high level, the detection signal is When the trailing edge of S3 is detected, the optical disc D corresponding to the disc number "81" is located at the loading position A.

Thus, the rotary table 1 is shown in FIG.
The number of pulse signals formed by the logical product of the detection signals S1 and S2 from the first and second photosensors while the detection signal S3 is at a high level when rotating in the direction of arrow B in FIG. Is m (m = 9,8,7 ...
.. In the case of 1), when the rising edge of the detection signal S3 is detected, the disc number "10m +
The optical disc D corresponding to "1" is located.

When the rotary table 1 is rotating in the direction of arrow B in FIG. 4, the detection signal S3
However, this time, in the low level period, when the number of pulse signals formed by the logical product of the detection signals S1 and S2 from the first and second photosensors is two, the rising edge of the detection signal S3 is detected. At this point, the optical disc D corresponding to the disc number “89” is located at the loading position A, and during the period when the detection signal S3 is at a low level, the optical signals from the first and second optical sensors are detected. When the number of pulse signals formed by the logical product of the detection signals S1 and S2 is three, the optical disc D corresponding to the disc number “78” is located at the loading position A at the time when the trailing edge of the detection signal S3 is detected. You are doing it.

Thus, the rotary table 1 is shown in FIG.
The number of pulse signals formed by the logical product of the detection signals S1 and S2 from the first and second photosensors while the detection signal S3 is at a low level when rotating in the direction of arrow B in FIG. Is m (m = 2, 3, 4, ...
······························································································································ Detected the rising of the detection signal S3.
The optical disc D corresponding to (11-m) +1} -m "is located.

In this case, exceptionally, when the number of pulse signals formed by the logical product of the detection signals S1 and S2 from the first and second photosensors is 10 during the period when the detection signal S3 is low level. In reality, there are 11 cases. In this case, the optical disc corresponding to the disc number “100” is located at the loading position A at the time when the rising edge of the detection signal S3 is detected. .

From the above, the detection signal S3 from the third optical sensor is a signal (hereinafter referred to as range signal) indicating the range corresponding to the unevenness formed on the second detection plate 133b according to different pitches. , And at the time when the rising and falling edges of this range signal are detected,
The optical disc D with a specific disc number is rotatably conveyed to the loading position A.

Considering a case where the rotary table 1 is stopped when the optical disk D at this specific disk number reaches the loading position A, the stop position is shown as a concept of an address used in a memory or the like. ,
The stop position at the time when the rise and fall of the range signal (detection signal) is detected can be recognized as the absolute address of the optical disc D at the specific disc number.

The pulse signal formed by the logical product of the detection signals S1 and S2 from the first and second photosensors shows the relative address to the absolute address shown by the range signal.

More specifically, from the state in which the rotary table 1 is stopped with the optical disc D having the disc number "7" being at the loading position A, the optical disc D having the disc number "13" is placed at the loading position A.
To position and stop the rotary table 1,
That is, when moving from the absolute address “7” to the absolute address “13”, for example, when rotating in the direction of arrow C in FIG. 4, the absolute address “7” in FIG. become. At this time, paying attention to the waveform of the detection signal S3 from the third optical sensor, the high level is only at the absolute address "11".
By counting the relative addresses during the period when 3 is at the high level, it is understood that the absolute address at the time when the detection signal S3 from the third optical sensor changes from the high level to the low level is "12". Therefore, it is found that the stop position where the relative address is further increased by "1" is the absolute address "13".

Next, from the absolute address "13" to the absolute address "2"
When moving to "2", it is known that the number of relative addresses where the detection signal S3 from the third optical sensor is low level is "2" by the time the movement is started. When the movement starts, the relative address will increase by one. When the relative addresses that are sequentially updated are counted, the relative address number is "9" when the detection signal S3 from the third optical sensor changes from the low level to the high level. It can be seen that the absolute address at the time of this change is "21". Therefore, the absolute address "22" is the stop position obtained by incrementing the relative address by one. The same applies to the rotational movement in the direction in which the relative address is reduced (the direction indicated by the arrow B in FIG. 4).

When the power is turned on, the absolute address is not known, but the relative address number of the section in which the detection signal S3 from the third optical sensor is at the high level or the low level is counted, whereby the rotary table 1 It is possible to know the absolute address at an early point without rotating one turn.

As described above, according to the rotation position detecting mechanism 44 of the present embodiment, when the rotary table 1 is stopped by positioning the optical disc D having a desired disc number at the predetermined loading position A, Further, the optical disc D having the desired disc number can be accurately conveyed to the predetermined loading position A and stopped. Moreover, when the power is turned on, the rotary table 1 is not rotated once, and the loading position A
It is possible to quickly know which disc number of the optical disc D is located at. In the above example,
Although the case where a specific optical disc D among 100 optical discs is conveyed to the loading position A is shown, it can be applied to a rotary table accommodating 100 optical discs D or more.

Next, the circuit system of the reproducing apparatus according to this embodiment will be described with reference to FIG. The circuit system in this reproducing apparatus includes a detection circuit system 151 including various sensors and switches, and a drive control circuit system 152 that supplies a drive current to drive sources (motors and the like) of various mechanisms equipped in the reproducing apparatus. , The above-mentioned controller 141 that outputs a drive signal and a control signal to the drive control circuit system 152 based on various detection signals from the detection circuit system 151 and a control signal from a system controller 154, which will be described later, and the operation panel 11. Input signals from various operation keys are supplied, and the input signals are used as data in the memory 15
The information signal reproduced by the system controller 154 registered in No. 3 and the optical pickup 82 of the reproducing unit 43 is converted into, for example, an audio signal and output, and a tracking error signal and a focusing error signal are extracted from the information signal. And a reproducing circuit system 155 for supplying to a servo circuit system (not shown).

Further, the system controller 154 has
The number of LEDs corresponding to the group is connected, and the display unit 28 (see FIG. 2) is further provided through a character display circuit (not shown).
Are connected. The memory 153 is composed of, for example, SRAM, and a file corresponding to the disk number is logically allocated to the array variable area. In addition,
A backup circuit 156 is connected to the memory 153 so that the data in the memory 153 is not erased even when the power switch 21 on the operation panel 11 is turned off. Here, the disc number is the number "1" corresponding to the slit 4 which is predetermined in the rotary table 1 as described above.
~ "100".

As shown in FIG. 24, each file has a flag area a which is bit-allocated corresponding to the group number.
And a memo storage area b in which a memo about the corresponding disk number is stored as code data such as alphanumeric characters and katakana characters, a disk number registration area c in which a disk number corresponding to the file order is registered, and a disk is present (1) / No (0) bit d. Each bit of the flag area a indicates whether the corresponding group is registered or not registered. For example, when “1” is set at the 1st bit, the 3rd bit and the 5th bit, group 1 and group 3 and group 5 indicate that the disk number is registered.

On the other hand, various operation keys connected to the system controller 154 are keys and operation buttons arranged on the operation panel shown in FIG. 2, but in FIG. Group key 23
(23a, 23b ... 23j), rotary operation key 26
Also, only the push button switch 27 is shown.

Next, the processing operation of the reproducing apparatus according to this embodiment, in particular, 100 optical disks D set on the rotary table 1 are grouped and managed by group, for example, performer, genre and user. 25 to 28 for the group registration operation for recording, a memo input process for registering a memo (title, etc.) for each disc number, and an operation for selecting and reproducing one optical disc D from the above 100 optical discs D. The description will be made with reference to the flowchart of FIG.

First, as shown in FIG. 25, the group registration processing is started by operating the group entry key 24 (step S1), and the group registration program is transferred to the RAM area of the system controller 154. Then, the playback device is set to the group registration mode (step S2).

Then, in the next step S3, 10
It is determined whether any one of the group keys 23 has been operated. When one group key 23 is pressed, the process proceeds to step S4, the LED arranged above the operated group key 23 blinks in green, and at the same time, the group number display area 2 of the display unit 28 is displayed.
In 9, the group number corresponding to the operated group key is displayed. Then, the disk number setting processing routine is entered (step S5).

In this disk number setting process, as shown in FIG. 26, it is determined in step S101 whether or not the rotary operation key 26 has been rotated rightward (clockwise). When the rotary operation key 26 is rotated rightward, the process proceeds to step S102, and the disc number currently displayed in the first disc number display area 31a is incremented by +.
1 is displayed. In this case, if the displayed disk number is "100", it is displayed as "1".

On the other hand, when the rotary operation key 26 is rotated leftward, the process proceeds to step S103, where
A number obtained by subtracting -1 from the disc number displayed in the first disc number display area 31a is displayed. In this case, if the displayed disk number is "0" or "1", it is displayed as "100".

Then, each time the disc number is displayed, it is determined in the next step S104 whether or not the push button switch 27 has been operated. Push button switch 27
If is not operated, the process returns to step S101 again to determine whether or not the rotary operation key 26 has been rotated to the right, and the routine of steps S101 to S104 is repeated until the push button switch 27 is operated. When 27 is operated, for example, the currently displayed disk number is stored in the disk number working area, and the process ends.

Returning again to the processing routine of FIG. 25, in the next step S6, among the many files registered in the memory, the file corresponding to the disk number stored in the disk number working area is stored in the RAM area. After reading, the bit corresponding to the group number of the operated group key in the flag area a of the read file is set.

In the next step S7, it is determined whether or not the file key 32 has been operated. File key 3
When 2 is operated, the process proceeds to step S8, and the file in the RAM area is registered in the original file in the memory based on the disk number stored in the disk number working area. That is, it overwrites.

Then, in the next step S9, the LED arranged above the operated group key 23 is lit in green, and the group registration process is completed.

On the other hand, in step S3, the group key 23
If it is determined that is not operated, step S1
Go to 0. This step S10 is a step of waiting for an input operation by the group key 23 for a certain period (16 seconds in this example), and when there is no input by the group key 23 even after 16 seconds, the state before step S1, that is, Normal key input waiting state (hereinafter simply referred to as normal state)
Then, the process ends by returning to step S11.

Further, in step S7, the file key 32
If it is determined that is not operated, step S1
Go to 2. This step S12 is a step of waiting for an input operation by the file key 32 for a certain period (16 seconds in this example), and if there is no input by the file key 32 even after 16 seconds, it returns to the normal state and ends. (Step S13).

Next, as shown in FIG. 27, the memo input process is started by operating the memo input key 25 (step S201), and a memo input program is stored in the RAM area of the system controller 154. Transfer and set the playback device to memo input mode (step S
202). At this time, a cursor for input is displayed at the leading digit of the memo display in the memo display area 30 of the display unit 28.

Thereafter, the disk number setting processing routine is entered (step S203). Since this disk number setting processing routine has been described in detail, its explanation is omitted here.

Then, in the next step S204,
It is determined whether or not the rotary operation key 26 has been operated. When the rotary operation key 26 is operated, the process proceeds to the next step S205, and the character or number displayed at the position of the cursor is updated by the number corresponding to the number of clicks of the rotary operation key 26. For example, if the character or number displayed at the cursor position is, for example, the letter "M", click the rotary operation key in the clockwise direction +1
When the rotation operation is performed, the display is updated in the positive direction of the alphabet and changes to "N" of the alphabet.
On the contrary, when the rotary operation key is clicked counterclockwise by +1 and the rotary operation is performed, it changes to the alphabet "L".

This process is repeated until a character or number satisfying the registration is displayed at the digit where the cursor is located (step S206). Then, when the cursor is to be moved to the next digit, the push button switch 27 is operated (steps S207 and S208). After the cursor is moved to the next digit, the rotary operation key 26 is used to update the digit or character until a satisfactory character or number is displayed. By repeating these processes, a memo about the disk number is created. This created memo data is RA
It is temporarily stored in the working area for memo on the M area.

When it is determined in step S204 that the rotary operation key 26 has not been operated, the process proceeds to step S209. This step S209 is a step of waiting for an input by the rotary operation key 26 for a certain period (16 seconds in this example), and if there is no input by the rotary operation key 26 even after 16 seconds, it returns to the normal state. And ends (step S210).

On the other hand, if it is not necessary to move to the next digit in step S207, the process proceeds to step S211.
It is determined whether the file key 32 has been operated.
The file key 32 is used to determine whether or not the memo input process has been completed. When the file key 32 is operated, the process proceeds to the next step S212, and the memo stored in the memo working area. The data is registered in the memo storage area b of the file corresponding to the disk number stored in the disk number working area among the many files registered in the memory 153. Then, it returns to the normal state and ends (step S213).

Next, as shown in FIG. 28, the reproducing process is as follows.
The processing is started by operating the group key 23 (step S301), and the system controller 15
The reproduction processing program is transferred to the RAM area 3 and the reproduction apparatus is set to the reproduction mode (step S302).
At this time, in the group number display area 29 of the display unit 28,
The group number corresponding to the operated group key 23 is displayed.

Then, in the next step S303, the file in which the bit corresponding to the group number in the flag area a is “1” is searched from among the many files registered in the memory 153, and the file is found. R all files
Reading is performed in order of the disk number to the file working area in the AM area. In this search process, if there is a file in which the group number is registered, the process proceeds to the next step S304, and the LED arranged above the operated group key 23 blinks in red. From this state, the input of the rotary operation key 26 is awaited. That is, it is determined whether or not the rotary operation key 26 has been operated (step S305).

When the rotary operation key 26 is operated, the process proceeds to the next step S306, in which the files read in the RAM area are sequentially updated according to the rotation of the rotary operation key 26, The disk number registered in the disk number registration area c of the updated file and the memo stored in the memo storage area b are displayed in the first disk number display area 31a and the memo display area 30 of the display unit 28, respectively. . Further, in this example, the disk number registered in the disk number registration area c of the file to be updated next is displayed in the second disk number display area 31b of the display unit 28. Further, in this example, when the disk presence (1) / absence (0) bit of the updated file is “0”, the memo storage area 3 of the display unit 28 is displayed.
At 0, a message indicating that the optical disc D is not set, for example, "No Disc" is displayed.

Then, for each display of the disk number and the memo, the push button switch 2 is pressed in the next step S307.
It is determined whether 7 has been operated. If the push button switch 27 is not operated, the step S305 is performed again.
Returning to, it is determined whether or not the rotary operation key 26 has been operated, and the routine of steps S305 to S307 is repeated until the push button switch 27 is operated.

When the push button switch 27 is operated,
In step S208, the information signal is reproduced on the optical disc D having the displayed disc number. That is, when the push button switch 27 is operated, the system controller 154 instructs the controller 141 to output data indicating the device number of the drive target (in this case, the device number of the motor 45 of the rotary drive mechanism 41 in FIG. 3) and the rotation request. Is transmitted.

The controller 141 analyzes the data supplied from the system controller 154 and supplies a drive signal and a deceleration request signal to the drive control circuit corresponding to the device (motor 45) to be driven in the drive control circuit system 152. To do. As a result, a drive current is supplied from the target drive control circuit to the motor 45 of the rotary drive mechanism 41 in FIG.
As a result, the rotary table 1 is driven to rotate.

Simultaneously with the rotation of the rotary table 1, the rotational position detection mechanism 44 shown in FIG. 3 detects the rotational position of the rotary table 1, and when the optical disc D at the target disc number reaches the loading position A, the controller A stop signal is output to 141. The controller 141, based on the supply of the stop signal from the rotational position detection mechanism 44, drives the motor 45 in the rotational drive mechanism 41.
And outputs a stop signal to the drive control circuit. As a result, the supply of the drive current from the drive control circuit to the motor 45 is cut off, and the rotary table 1 is stopped. That is, the rotary table 1 is stopped when the optical disc D corresponding to the target disc number reaches the loading position A.

Thereafter, the system controller 154
A signal is provided to the controller 141 that directs control to the loading mechanism 42. Controller 141
The loading mechanism 4 based on the supply of the instruction signal.
The drive signal is output to the drive control circuit corresponding to the second motor (the motor 51 that drives the cam 60). This drive control circuit supplies a drive current to the motor 61 based on the supply of the drive signal from the controller 141, and causes the cam 60 to move as shown in FIG.
Rotate clockwise. With the clockwise rotation of the cam 60, the first and second arms 54 and 55 of the loading mechanism 42 rotationally convey the optical disc D at the loading position A to the mounting position B.

When the target optical disk D reaches the mounting position B, the rib 71 of the cam 60 comes into contact with the other contact of the two-position switch 72, and this contact causes a detection signal from the two-position switch 72 to the controller 141. Is output. The controller 141 outputs a stop signal to the drive control circuit of the motor 61 based on the supply of the detection signal. As a result, the motor 61 from the drive control circuit
The supply of the drive current to the cam is cut off, and the rotation of the cam 60 is stopped.

Thereafter, the system controller 154
A signal for instructing to transfer the control to the chucking mechanism 111 shown in FIG. 17 is given to the controller 141. The controller 141 outputs a drive signal to the drive control circuit corresponding to the motor 103 of the chucking mechanism 111 based on the supply of the instruction signal. This drive control circuit is based on the supply of the drive signal from the controller 141 to the motor 1
A drive current is supplied to the motor 03 to rotate the main gear 106. The slider 99 moves upward with the rotation of the main gear 106, and the optical disk D at the mounting position B is clamped by the reproducing unit 43 by the upward movement of the slider 99. At this time, the restriction on the elastic force of the floating means 86 by the locking means 93 is released, and the vibration transmission from the outside to the reproducing unit 43 is cut off.

Then, the system controller 154
A signal is given to the controller 141 to instruct control to be transferred to the reproduction unit 43. Based on the supply of the instruction signal, the controller 141 energizes the spindle motor of the reproducing unit 43 to rotate the optical disc D in one direction, and also moves the optical pickup 82 in the radial direction of the optical disc D to make a pit in the optical disc D. Play the information. The reproduction signal from the optical pickup 82 is supplied to the reproduction circuit system 155 and separated into an audio signal, a tracking error signal and a focusing error signal. The audio signal is output from the output terminal φout of the reproducing circuit system 155, and each error signal is supplied to a servo circuit system (not shown).

The system controller 154 turns on the LED arranged above the operated group key 23 in red when the reproduction process for the optical disc D is started (step S309).

The optical disc D is loaded at the loading position A.
If there is not, the corner side end 5 of the second arm 55
Since the detection switch 70 is turned on at 5a, this ON signal is supplied to the system controller 154 via the controller 141. System controller 15
4 indicates that among a large number of files read in the RAM area, the disk presence / absence bit of the file corresponding to the disk number of the optical disk D to be reproduced is changed to "0".
Register and proceed to step S309 as it is.

When the processing of step S309 is completed, a large number of files in the RAM area are overwritten to the corresponding files among the 100 files in the memory 153, and the series of processing is completed.

On the other hand, if it is determined in step S303 that the group corresponding to the operated group key 23 is not registered, the process proceeds to step S310 and the display unit 2
An error message (for example, "NO ENTRY") is displayed in the memo display area 30 of 8 for, for example, 1 to 2 seconds. When the display of this error message is completed, the process proceeds to step S311 to return to the normal state and end.

If it is determined in step S305 that the rotary operation key 26 has not been operated, the process proceeds to step S312. In this step S312, input by the rotary operation key 26 is performed for a certain period (16 seconds in this example).
This is a step of waiting only, and if there is no input by the rotary operation key 26 even after 16 seconds, it returns to the normal state and ends (step S313).

In this reproducing apparatus, when the rotary operation key 26 is simply operated from the normal state,
The optical disc D is reproduced based on the file read in the file working area of the system controller 154. That is, the files are sequentially updated according to the rotating operation of the rotary operation key 26, and the reproduction is performed on the optical disk D corresponding to the disk number registered in the disk number registration area c of the updated file. Even in this case, of course, the disc number of the optical disc D to be reproduced is displayed in the first disc number display area 31a, and the disc number to be updated next is displayed in the second disc number display area 31b. It

The above description of the reproduction mode is mainly directed to the continuous reproduction mode (generally referred to as CONTINUE mode). When the CONTINUE mode is desired, the upper right portion in the lower center of the operation panel 11 is described. It can be set by operating the CONTINUE key 201 located on the left side of the three mode setting keys 201, 202 and 203 arranged in. At this time, the LED installed above the key 201 is turned on.

The remaining two modes, that is, the single-image playback mode (generally referred to as SHUFFLE mode) and the program mode (PROGRAM mode), are set at the center among the three mode setting keys 201, 202 and 203. It can be set by operating the SHUFFLE key 202 located and the PROGRAM key 203 located on the right side. In this case, the LEDs above the keys 202 and 203 are selectively turned on.

Like the CONTINUE mode, in the SHUFFLE mode, the optical disc D is reproduced based on the file read in the file working area of the RAM area of the system controller 154. The optical disk D can be randomly selected with the rotary operation key 26. That is, by rotating the rotary operation key 26, one disc number is randomly selected from the disc numbers of the files read in the file working area, and the optical disc D to be reproduced next is set. Is. In this case, the second
The selected disc number is displayed in the disc number display area 31b.

In the PROGRAM mode, the order of files read in the file working area of the RAM area of the system controller 154 is set by the rotary operation key 26.
The optical disc D is reproduced based on the changed file. In this case, the above CONT
Similar to the INUE mode, reproduction is performed in the order of the files, and the second disk number display area 31b displays the disk number of the file next to the file to be reproduced.

As described above, in this reproducing apparatus, since various kinds of data are updated by the rotary operation keys 26, normally, in the reproducing apparatus capable of reproducing a large number of optical discs D, data setting is performed. When performing, it was necessary to input and update using many keys, but it is possible to substitute many of these keys with one rotary operation key 26, which simplifies the key arrangement on the operation panel 11. In addition, since data updating can be performed by an easy-to-understand operation such as rotation, anyone can easily perform a data registration operation that generally requires a complicated operation. The operability of can be improved. Moreover, since a memo is registered for each disk number, it becomes possible to perform group registration while referring to the disk number and the memo, which simplifies confirmation work during registration and reduces erroneous registration. be able to.

Also, the first disc number display area 31a
Since the disc number currently being reproduced is displayed in the second disc number and the disc number to be reproduced next time is displayed in the second disc number display area 31b, there is a conventional problem in the reproducing apparatus capable of reproducing a large number of optical discs D. I don't understand the disadvantage that has been said, that is, what is played (played) next,
It is possible to solve the problem that the order has to be confirmed by key operation, and the operability and convenience can be further improved.

If a plurality of optical discs D are stored in the rotary table 1 as described above, a plurality of mother-owned optical discs D and a plurality of father-owned optical discs D are mixed, and the plurality of optical discs D are mixed. It becomes difficult to select the desired optical disc D from the above. In addition, it is rare to listen through all the songs recorded on one optical disc D, and it is common to select and listen to only a desired song from a plurality of songs. Because of this, it would be very convenient to stock the optical disc D and songs that one likes.

The reproducing apparatus has such functions as the first to fourth music clip keys 251 to 252 shown in FIG.
I decided to give it to 54.

[0227] These music clip keys 251-
When 254 is used, it is preferable that the first music clip key 251 is a mother's key and the second music clip key 252 is a father's key.

The reproducing apparatus, as shown in the flowchart of FIG.
Depending on the state of the reproducing apparatus when 254 is turned on, it is determined whether the music piece is clipped (registered in a group) or music already clipped is reproduced.

That is, the flow chart shown in FIG. 29 is started by turning on the main power source, and proceeds to step S500.

In the above step S500, the system controller 154 shown in FIG. 23 determines whether or not the designated music is being reproduced (or the reproduction is temporarily stopped). If YES, the process proceeds to step S501. In step S502, the clip file processing routine is executed. In step S502, the clip file reproduction (clip play) processing routine is executed.

The above clip file processing routine is as follows:
It is as shown in the flowchart of FIG.

That is, in the flow chart shown in FIG. 30, each of the music clip keys 251 to 254 is displayed while the music is being reproduced (or the reproduction is temporarily stopped) as described above.
Is started by turning on any of the
It proceeds to step S400.

In step S400, the system controller 154 detects the music clip key that has been turned on, displays the character "CLIP FILE", for example, and controls the display unit 28 to blink the character. Data indicating the music clip key that has been turned on is transferred to the system controller 1
A memory (not shown in the drawings.
It is called IPTBL. ) Once and store in step S401
Proceed to.

In step S401, the system controller 154 stores in the memory 153 such as S-RAM, a plurality of registration data (hereinafter, referred to as a plurality of registration data indicating addresses, song numbers, etc., of songs clipped in the past. It is determined whether or not there is a music piece clipped in the past with respect to the music clip key that has been turned on, by determining whether or not all of them have been recorded. Proceeds to step S402, and if NO, proceeds to step S407.

[0235] In step S402, the CCAL
Has been stored in the memory 153, the system controller 154 reads all CCALs of the clip file from the memory 153. And this CCA
The file number of the clip file based on L,
A music calendar 31c formed by the song numbers of all the songs that make up the clip file, and a display unit 2 for displaying the title when the clip file has a title in the clip memo mode described later.
8 is controlled and it progresses to step S403.

On the other hand, in step S407, since the CCAL belonging to the clip file is not stored in the memory 153, the system controller 15
4 clears the CCAL and proceeds to step S403.

In step S403, the system controller 154 controls the display unit 28 so that the music calendar 31c displayed on the display unit displays the music number of the music currently being reproduced (or the reproduction is temporarily stopped). Then, the process proceeds to step S404.

[0238] In step S404, the so-called TOC (Tabl (Tabl)
e of Contents) data, the number of the currently playing optical disc D (the number indicating the position on the rotary table 1 or the number of the optical disc D itself), and the number of the song in the clip file. The disc number registration area 153a displays registration information indicating a song number indicating the song order.
The memory 153 is write-controlled to be newly written into the memory, and the process proceeds to step S405.

When a title or the like is added to the clip file in the clip memo mode described later, this title data is written in the character data storage area 153b as character data.

In step S405, when the system controller 154 registers the registration information in the clip file for the first time, data indicating that the registration information is registered in the clip file (hereinafter referred to as a file tag). Are formed and the process proceeds to step S406.

In step S406, the system controller 154 controls the writing of the memory 153 so that the file tag is written in the flag area 153c. Further, the LED provided on the music clip key that has been turned on is controlled to be lighted, and the display unit 28 is controlled to display the blinking character "CLIP FILE" for a predetermined time.
Further, the display unit 28 is controlled to display the music calendar showing all the song numbers in the clip file, and the routine of this clip file is ended. This allows the user to recognize that the song has been music clipped.

In this way, while the desired music is being reproduced (or while the reproduction is temporarily stopped), the music being reproduced is clipped by a simple operation of turning on the desired music clip keys 251 to 254. be able to.
Therefore, by repeating the reproduction of the desired music (or the temporary stop of reproduction) and the ON operation of the music clip key, a plurality of data of the desired music (the CCAL) are grouped in the memory 153. It will be remembered.

The music clip key is turned on in an attempt to make a clip file of the song currently being played. However, if the user finds that this is a mistake, the user again presses the same music clip key during playback of the song. Turn on. As a result, the system controller 154 controls the display unit 28 so that the letters "CLIP FILE" blink. The user turns on the erase key 255, which will be described later, while the character “CLIP FILE” is blinking. This allows
The system controller 154 controls the memory 153 so as to delete the registration information of the clip file that is currently being reproduced from the clip file.

Next, the reproduction (clip play) of the music clipped as described above is performed according to the routine shown in the flowchart of FIG.

That is, the flowchart of FIG. 31 shows that when any one of the music clip keys 251 to 254 is not at the time of reproduction or the reproduction primary stop (for example, at the time of stop, fast forward, fast rewind, etc.). It is started by being turned on at step S410.
Proceed to.

In step S410, in order to be able to reproduce the optical disc D currently mounted in the reproducing section when no music clip is recorded in the clip file of the music clip key turned on, The system controller 154 sets the disc number of the optical disc D mounted in the reproducing unit to the CL which is the RAM in the system controller.
Store in IPTBL and proceed to step S411.

In step S411, the system controller 154 stores the data indicating the music clip key that has been turned on in the CLIPTBL, and proceeds to step S412.

In step S412, the system controller 154 searches the music file registration of the clip file of the music clip key that has been turned on based on the CCAL stored in the memory 153, and proceeds to step S413. .

In step S413, the system controller 154 determines whether or not a music piece is registered in the clip file. If a song is registered in the clip file, step S41
In step 4, if no music is registered in the clip file, this routine is finished as it is.

If the music is not registered in the clip file indicated by the music clip key, the system controller 154 will display "NO", for example.
The display unit 28 is controlled so as to display the character "FILE". This allows the user to recognize that the music is not registered in the clip file indicated by the music clip key.

In step S414, the system controller 154 designates a plurality of optical discs D and sequentially designates a plural disc continuous playing mode in which the discs are recorded. It is determined whether or not a random performance mode for designating a random performance is designated, and if YES, step S41.
7, the process proceeds to step S415 if NO.

In step S415, the system controller 154 determines whether or not a music piece clipped on the optical disc D currently loaded in the playback section is recorded. If YES, then the system controller 154 determines in step S419. If NO, the process proceeds to step S416.

At the step S419, since the music clipped on the currently loaded optical disc D is recorded, the system controller 154 is operated.
Reads the CCAL indicating the address of the music piece in the clip file, etc. from the memory 153.
Optical disc D on which the music is recorded based on CAL
The rotary table 1 so that the
And controlling the reproducing circuit system 155 so as to access the address of the music piece in the clip file on the optical disk D and reproduce the same.
Proceed to 18. As a result, the music of the clip file is reproduced.

In addition, if the title to be reproduced is added to the music to be reproduced based on the CCAL (described later), the system controller 154 reads it from the character data storage area of the memory 153. The display unit 28 is controlled to display. As a result, the user can be made to recognize the song title and the like of the song currently being played.

Further, the system controller 154
At the time of this clip play, the LED indicating the normal reproduction state is turned on, the display unit 28 is controlled so as to display characters such as "CLIP PLAY", and the current reproduction is performed as shown in FIG. The display unit 28 is controlled so as to display the song number 31a of the currently played song, the number of the clip file, the song number 31b of the song to be reproduced next, and the music calendar 31c showing all song numbers of the clip file.

As a result, the user can be made aware in advance which song will be reproduced next. Therefore, for example, if the user wants to skip the next song and listen to it, he / she can select a song after the next song by using the song skip key at the end of the reproduction of the current song. It is possible to improve the sex.

In step S416, the system controller 154 determines whether or not the one-disc mode for designating the reproduction of only the optical disc D currently mounted in the reproducing section is selected. Since there is no song clipped in the loaded optical disc D, this routine is finished as it is, and if YES, the process proceeds to step S417.

When the clip play is not possible in the 1-disc mode, the system controller 154 causes the display unit 28 to display a character such as "The next clip play cannot be performed because of the 1-disc mode". Control. This allows the user to recognize the erroneous operation.

The step S417 is the step S417.
If it is determined at 414 that the multiple-sheet continuous playback mode is also the random performance mode, and step S41 described above.
This is the step to proceed when it is determined in 6 that the 1-disk mode is not selected. The system controller 154 is
In this step S417, the CCAL that is a clip file is read from the memory 153, and the rotary table 1 is controlled so that the optical disc D to be played back based on this CCAL is mounted in the playback unit, and at the same time the optical disc D The reproducing circuit system 155 is controlled so as to access the address of the music piece in the clip file and reproduce the program, and the process proceeds to step S418. As a result, the music (clip play) of the above-mentioned clip file is reproduced.

In step S418, the system controller 154 determines whether or not the reproduction of the music piece clip-played is completed, and if NO, repeatedly executes this step S418 until the reproduction of the music piece is completed. Y
In the case of ES, the process returns to step S414.

When the system controller 154 finishes playing all the songs in the clip file,
The above routine is repeatedly executed until the stop key for designating the stop of the reproduction is turned on.

As described above, when the music clip keys 251 to 254 are turned on while the music is being reproduced (or when the reproduction is temporarily stopped), the music reproduction device clips the music and files the music while the music is stopped. When the clip keys 251 to 254 are turned on, the music registered in the clip file of the music clip key is clip-played. For this reason, it is possible to easily reproduce the clip-filed music by one key operation. In addition, it is possible to prevent the inconvenience of having to reprogram a desired song each time it is played back, thereby improving convenience.

[0263] Next, the music piece clipped as described above can be erased (clip erase) at any time while the clip file is available or during clip play.

The clip erase processing routine is as shown in the flowchart of FIG. That is, in the flowchart shown in FIG. 32, the music to be clip-erased is reproduced by the clip play or by the user individually designating a desired music, and the erase key 255 is turned on when the music is being reproduced. As a result, the process starts and the process proceeds to step S420.

In step S420, since the erase key 255 has been turned on, the system controller 154 detects the registration information of the currently reproduced song from the four CCALs stored in the memory 153. And proceeds to step S421.

At step S421, the memory 1
The registration information of the song currently being reproduced is erased from the CCAL stored in 53 and the process proceeds to step S422.
