Abstract

PURPOSE:To prevent a misclamping or the like due to some external force by providing plural plate type trays holding disks on their primary sides and forming the flexible shift preventing projections to those trays at the places in the vicinity of the disk holding sides respectively. CONSTITUTION:The soft members 11f and 12f made of the synthetic leather, etc., are provided to the trays 11 and 12 so as to project them over the prescribed positions of the primary sides of both trays that can be opposed to the disk holding sides more than main surface. In addition, the arc-shaped recess parts 11h, 11i, 12h and 12i are formed. Thus the size of each tray is reduced in the piling direction. Then the flexible shift preventing projections 11j-11l and 12j-12l are provided at the places in the vicinity of the disk holding sides of both trays 11 and 12 respectively. These projections protrude over the disk holding sides by an amount larger than the thickness of a disk 10 in the direction (arrow head Z) intersecting orthogonally with the disk holding sides of the trays in case the trays can interlock a magazine main body 8 or the adjacent trays with each other or protrude over the main body 8.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc holder that holds a disc and is detachably incorporated into the main body of a multi-disc player.

BACKGROUND ART A jukebox is generally known as a disc brake that can store a plurality of discs and can sequentially select any of the discs to play continuously. However, conventional jukeboxes have very large bodies, making them unsuitable for home use.

In recent years, it has been called a digital audio disc (hereinafter abbreviated as DAD), and by recording digital signals, it is possible to increase the amount of information that can be stored compared to the conventional audio disc that contains analog signals, and it is easier to play. Several types of disks that generate less noise have been developed and are widely used.

Among these, disks with an outer diameter of approximately 12 cm, which are generally called compact disks and which record and read signals using laser light, are easy to handle and allow the overall size of the disk player to be miniaturized. It is something. Recently, I have been using multiple pieces of this small DAD (for example, 5 to 6 pieces).
A multi-disc player that can be stored at all times and is ideal for use as a home jukebox that plays these discs continuously has been developed. By the way, a small DAD has a performance time of one hour and can accommodate approximately 1.5 times the amount of information as a conventional analog audio disc. Therefore, for example, six discs can store about 120 songs with a performance time of around 3 minutes, and it is easy to cover them by your favorite genre, such as jazz or enka.

A multi-disc player basically includes a playing means including a turntable, a pickup, etc., a disc holder that holds a disc and is inserted into a mounting part in the player housing, and a disc in the disc holder that is placed at a playing position. In other words, it includes a disk ejecting and conveying mechanism that conveys the disk onto the turntable.

In a multi-disc player, when a disk in a disk holder is conveyed onto a turntable, the disk is moved in two directions, for example, in a direction parallel to the disk supporting surface of the turntable and in a direction substantially perpendicular thereto. However, in the multi-disc player that has already been developed, the disc ejecting and transporting mechanism for carrying out this transport directly picks up the disc in the disc holder, the end of the disc in the direction in which it protrudes from the disc holder, or almost the entire disc. It is of the type that is gripped and pulled out of the disc holder, and the configuration of the disc ejecting and transporting mechanism, including the gripping mechanism that grips the disc, is large and complicated. Furthermore, the space required for its operation is large, and the entire player is It is difficult to miniaturize the device as well as increase the cost.

Recently, in an attempt to solve this problem, for example, the patent application
As proposed as No. 04303, the disk holder is composed of a housing and a plurality of plate-shaped trays each capable of supporting a disk on its main surface and protruding from the housing along each main surface. A new multi-disc player has been developed. That is, the disc is configured such that the disc is transported in one direction (the disc is transported in a direction parallel to the disc-supporting surface of the turntable) by simply protruding the plate-shaped trays each carrying a disc from the housing. -ing Therefore, in a multi-disc player as described above, a disc stored in a disc holder is directly gripped by the protruding end of the disc from the disc holder or substantially the entire disc by a complicated gripping mechanism, and then removed from the disc holder. The structure is simpler than that provided with a pull-out type disc ejecting and transporting mechanism, and it becomes easier to reduce the size and cost of the player as a whole.

However, when the disc holder is configured as described above, for example, when the plate tray carrying a desired disc is projected out of the housing in order to play a desired disc, some external force may be applied to the disc player. If this happens, there is a concern that the disk on the tray may shift in its radial direction, resulting in so-called misclamping.

1. The present invention has been made in view of the above points, and its purpose is to prevent the disc on the tray protruding from the disc holder body from shifting, thereby preventing misclamping etc. The purpose of the present invention is to provide a disc holder.

A disc holder according to the present invention includes a housing, and a plurality of plate-shaped trays each capable of supporting a disc on its main surface and protruding from the housing along each main surface and capable of being housed therein. In the vicinity of the supporting surface, there is a component capable of engaging the housing or an adjacent tray, and protruding from the disk supporting surface by more than the thickness of the disk in a direction perpendicular to the disk supporting surface when the tray projects outside the housing. It is characterized by being provided with a flexible anti-slip protrusion.

1 to 140 are each formed into a substantially flat plate shape, and
Rotating lever 141 detected by photo sensor 146
Rising portions 141a, 142a, and 143a extending upward (in the two directions of the arrows) are provided on 143 to 143.

Thereby, the two photosensors 145 and 146 are arranged along a plane parallel to the main surface of each tray 11 and 12. Although not shown,
A biasing means is provided for biasing each of the rotary levers 138 to 143 so that one end of the rotary lever approaches the outer circumference of the disk 10.

The above-mentioned rotating levers 138 to 143 and the photosensors 145 and 146 constitute disk presence/absence detection means for detecting the presence or absence of each disk in the magazine 5. That is, the photosensor 1 detects changes in the angular position of each rotating lever 138 to 143 due to the presence or absence of a disk.
45 and 146 to determine the presence or absence of a disc.

Next, the operation of the multi-disc player configured as described above will be briefly explained along the playing procedure with reference to FIGS. 28 to 32.

First, when a disc to be played is designated by operating the operation button group 6 shown in FIG. Start moving backwards (counter to arrow Y direction). Therefore, by the action of the stepped cam grooves 37d and 38d formed in the moving plates 37 and 38 and the guide groove 16e formed in the chassis 16, the bottle 20C, which is movably fitted into the groove, moves up and down. The movable member 18 including the movable chassis B20 on which the bin 20C is protruded moves up and down. The tray protruding member 53 provided on the moving member 18 thus reaches a position of engagement with the tray 11 or 12 carrying the disc to be played.

Here, the movement and positioning of the moving plate 37 back and forth,
Therefore, the vertical movement and positioning of the tray protruding member 53 will be described in detail.

The DCNT signal shown in FIGS. 28 and 29 is a slit detection signal emitted from the photosensor 51. Further, the DCHM signal is a detection signal emitted from the detection switch 49 that detects that the movable plate 37 is at its most backward movement position (forward movement limit position), that is, the home position.

As shown in FIG. 28, the photosensor 51
If there is a movement command while the T signal is being issued, the current address (current Disc) and desired address (search DIsG) are displayed.
The moving plate 37 is moved by a distance corresponding to the difference. Furthermore, if a movement command is received while the photosensor 51 is not emitting the DCNT signal, the moving plate 37 is moved back (forward) until the DCHM signal is emitted from the four detection switches, and then moves to the desired address ( Search D
ISC> position.

In this way, when the tray protruding member 53 is positioned at the engagement position with the tray carrying the disc to be played,
Next, the motor 62 starts rotating, and the movable body 56 is driven in the diagonal direction (in the opposite direction of arrow Y).

Therefore, the intermediate lever 70 is rotated counterclockwise in FIG. 10, and the second lever member 72 connected to the intermediate lever moves rightward (counterclockwise in the direction of arrow X). Second
As shown in FIG. 0, the second lever member 72
The first lever member 7 is
1 and is in a locked state. Therefore, the second lever member 71 also
The lever member 72 moves to the right, thereby rotating the tray protruding member 53, for example, clockwise in FIG. 10. Therefore, as shown in FIG. 2(b), a tray carrying a disc to be played (for example, tray B1)
2) protrudes from the magazine body 8, and the disc is attached to the disc supporting surface 23a of the turntable 23 (Fig. 11(b+
(see) to a concentric position with respect to the disc support surface, i.e., directly below the disc carrying surface. However, the rotation of the tray protruding member 53,
Therefore, immediately before the rightward movement of the first lever member 71 is completed, the locked state of the first and second lever members 71 and 72 by the locking/releasing means is released, and the subsequent first and second lever members 71 and 72 are released. The slight rightward movement of is caused by the coil spring 75 (
The arcuate portion 12n (see FIG. 2(b)) of the tray B12 pushed by the urging force of the movable chassis A19
The positioning of the tray is completed by contacting the tray 9c.

Note that completion of ejection of the tray from the magazine body 8 is detected by a detection signal from a detection switch 87 (see FIG. 8, etc.) activated by movement of the movable body 56. In addition, the flexible anti-slip protrusion 12j formed on the tray Bi2, etc.
Before the tray protrudes from the magazine body 8, it is in the state shown in FIG.

The second lever member 72, which has been released from the locked state with the first lever member 71, is further driven to the right (in the direction opposite to the arrow Support 79 of the clamping mechanism engaged by 79c
(shown in Figure 10) swings upward (in the direction of arrow Z). Therefore, the disc is lifted upward and clamped to the turntable 23 (the state shown in Figure 31).

Note that this upward movement of the disc is shown as Disc Load in FIG. Further, as the disk moves upward, the disk holding member 83 also rises together with the disk due to the rotation of the intermediate lever 70. However, when the loading of the disc onto the turntable is completed, the disc pressing member 83 is slightly detached from the disc, and the disc pressing member does not interfere with the rotation of the disc.

Here, the roller 111 shown in FIGS. 24 and 31
The operations of the lever member 112 and the like will be described in detail.

When the tray B12 protrudes from the magazine body 8, the roller 111 rotates while contacting the main surface of the disk 10 on the tray due to the urging force of the coil springs 115, 116. When the tray B12 has finished protruding, the disc 10 is positioned directly below the turntable 23. After this, the disc is moved upward by the clamp mechanism as described above, but as the disc moves upward, the lever Since the member 112 swings upward, the contact state of the roller 111 with the main surface of the disk is maintained. At the same time as the disk is clamped, the other lever member 113 is swung, for example, clockwise in FIG. The lever member 112 can also be further swung clockwise by a predetermined angle. As a result, the roller 111 separates from the main surface of the disk 10. Furthermore, as mentioned above,
The swinging of the lever member 113 is caused by the second lever member 72 (the tenth
(see figures, etc.).

On the other hand, as shown in FIG. 32, the rotation of the intermediate lever 70 causes the relay lever 132 to swing counterclockwise in FIG. 32 by a predetermined angle. Relay lever 13
2 is made by rotating the intermediate lever 70 only at the initial movement, and the subsequent oscillation DvJ operation is performed by the biasing force of the spring member 134. As the relay lever 132 swings, the first branch 132b of the relay lever engages with the bin 122C of the slider 122 and pushes the slider to the left (in the direction of the arrow X), thereby causing the other sliders 121 and 123 ( (Illustrated in Figure 25)
also move. Therefore, the locking pin 125 provided at the end of each slider fits into the locking hole 16g (shown in Figure 25) formed in the chassis 16 as a support member, and therefore the movable member 18 including the movable chassis B20 is The whole thing is locked to the chassis 16.

In this way, it becomes possible to play, and the turntable 23 and carriage 24 (see FIG. 9, etc.) operate to start playing.

When the performance is finished, the disc is stored in the magazine main body 8, but the disc storage operation is performed by following the reverse process of the disc loading operation described above, so a detailed description thereof will not be given. Thereafter, the above operation is repeated according to the specified number of songs.

Incidentally, the ejection operation of the magazine 5 to the outside of the player main body is performed by pressing the button for magazine ejection among the operation button group 6. When the magazine eject button is pressed, the movable body 56 (for example, see FIG. 19) is moved forward (in the direction of arrow Y) by a predetermined amount, thereby releasing the locked state of the magazine 5 by the locking member 67. As a result, the swing lever 64 shown in FIG. 10 etc. swings about the bin 64a, and the magazine 5 engaged with the free end of the swing lever is pushed out of the player body.

As detailed above, the disc holder (magazine 5) according to the present invention includes a housing (magazine main body 8), a housing (magazine main body 8), a disc holder 9 on each main surface, and a disc holder 9 along each main surface with respect to the housing. It has a plurality of plate-shaped trays (11, 12) that can be protruded and stored, and the trays can be engaged with the housing or an adjacent tray near the disk supporting surface, and the trays protrude outside the housing. At times, flexible anti-slip protrusions (11j, 11, 11Q) project from the disk supporting surface by more than the thickness of the disk in a direction perpendicular to the disk supporting surface.

12j, 12, and 12Q) are provided.

Therefore, even if some external force is applied while the tray is protruding from the disc holder main body, the disc on the tray will not shift in the radial direction, and misclamping etc. will be prevented. Therefore, it is suitable for use in, for example, an in-vehicle multi-disc player.
