What is the confirmation means for checking whether another disk is held on the holding section and whether or not the storage section for storing the other disk is located in the magazine 5? are doing.

The control section also includes automatic performance means that automatically performs a performance sequence that includes at least two discs unless a stop command is received, and a disc that checks whether a designated disc is stored in the magazine 5 or not. The present invention includes a first non-confirmation means and a music head detecting means for successively detecting the beginning of a famous piece of music recorded on a disc sequentially and continuously for a plurality of discs (for example, three discs).

Next, the operation of the multi-disc player configured as described above will be briefly explained along the playing procedure with reference to FIGS. 33 to 38.

First, as shown in FIG. 1, insert the magazine 5 from the magazine insertion port 3a (step S in FIG. 33).
+ ). First, the magazine 5 is supported on the FrUh plate 37 shown in FIGS. 7 to 9. In this state, press magazine 5 a little harder. When the magazine 5 is pushed, the slide plate 58 provided on the lower surface of the support plate 37 moves about 3M rearward (in the direction opposite to the arrow Y direction) together with the magazine against the biasing force of the coil spring 59. As a result, the detection switches 63 and 64 are activated, the motor 50 rotates, and the magazine 5 starts moving backward with the moving member 41 and the holding plate 37.
1 moves backward by a predetermined distance along the guide shaft 34, and the rear part of the moving member contacts the detection switch 65, and when the detection switch operates, the motor 50 stops and the magazine 5 is not loaded. Complete (step $2 shown in Figure 33).

Next, each operation button group 7 to 10 shown in FIG.
When a predetermined button is operated to specify the disc and song to be played (step S3), the control section (not shown) determines whether or not the designated disc is stored in the magazine 5. (Step $4)
). This confirmation is performed by photosensors 67 to 69. If the designated disk is not in the magazine 5, this is notified to the listener by an alarm, and the magazine is ejected to prompt replacement of the magazine 5 (step Ss). When it is determined that the specified disk is stored in the magazine 5, the vjun section transfers the disk holding section 85 (flowchart 1-
The photosensor 167 confirms whether other disks are supported on the disk holding section (hereinafter referred to as a tray) (step S6), and the magazine 5 has n storage sections for storing the other disks. The photosensors 67 to 69 confirm whether F and W are present (step/S).
7). If another disk is placed on the disk 101) section 85 (tray) and there is no storage section in the magazine 5 to store this disk, the magazine will be ejected to encourage replacement of the magazine 5. 1 to 3, and the listening name is notified by an alarm (step S). If there is a storage section in the magazine 5 that can store the other disk, or if the magazine is replaced with a magazine that does have a storage section, The other disk is placed in the magazine 5 by the push-out arm 121 (see Fig. 15).
(step S9).

When it is confirmed that there is no other disk on the disk carrier 85, the disk carrier 85 moves to the storage position of the specified disk 17fJ] I! 1. , is recognized (Step 5IG). The disk holder 85 is stopped at the designated disk storage position by the photosensors 162 and 212. When the disk carrier 15 portion 85 stops, the actuating rod 112 (see FIG. 15, etc.) is projected to the right (in the direction opposite to the arrow Xh), thereby actuating the trigger lever 26 (shown in the third figure) in the magazine 5. The disc 17 that should not be played (projects out of the J magazine 5 and moves onto the disc carrier 85 (step S!1).

The disc protruding from the magazine 5 is the 1" 1-cut lever 1.
47.148C'7 (shown in FIG. 15) Due to a defective Orl positioning, the disk is positioned at a predetermined position (directly above the seven turn deples) on the disk 1 holding part 85, and this is confirmed by the photosensor 167. ,[-evening 10

The operation of this clamp 13+M will be explained in a little more detail.

By moving the slide plate 179 to the left (in the direction of arrow X), the support arm 198 of the clamp mechanism first moves.
rotates about the rotation support shaft 187, for example, in the counterclockwise direction in FIG.

The support arm 198 is rotated once at a predetermined angle, and the pressing part 1 is
92 reaches directly above the turntable 79, the adjustment screw 201 installed on the support arm (the arm body 189, which is a component of the support arm) engages with the pin 202, and the rotation of the support arm is controlled. Stopped and hit. After this, the slide plate 179 is further driven to the left, and the pivot lever 196, which is a component of the support arm 198, pivots around the bin 196a, thus connecting with the pivot lever. The slide plate 194 moves along the 18 arm bodies. Therefore, as is clear from FIG. 13, the rib arm 190 moves downward one degree, and the pressing member 19
2 comes into contact with the main surface of the disk] 7, and the disk is clamped (step 514).

On the other hand, as the slide plate 179 moves to the left (in the direction of arrow X), the lever part UB183 shown in FIGS. 10 and 15 rotates counterclockwise in both figures about the bin 183a.

Then, as is clear from FIG. 15, the lever member B1
The bin 183C of 83 engages with the interlocking lever 149 and moves the interlocking lever I in the +1llJ direction (arrow Y direction). Therefore, the swinging levers 147, 14 and 8, which were used to position the disk 17 on the disk carrier 85,

> and the performance begins (step 515).

When the performance is finished, the disc is returned to the magazine 5 (step 816), but since the operation of returning the disc to the magazine 5 is almost the reverse of the disc loading operation described above, it will not be described in detail. However, disk 17 is inserted into the magazine 5 from above the disk carrier & S85.
The push-out arm 1 is shown in Figure 15.
It is done by 21. In addition, the above ai++ 1211
The sensor 67 detects whether there is a storage section in the magazine 5 for storing the disk to be returned.
Confirm by 69. As shown in FIG. 15, when the push-out arm 121 is in the push-out position for pushing out the disk 17, the tip of the push-out arm seems to come into contact with the magazine 5, but the magazine 5 has a notch 5b in this part. is formed, so the movement of the first arm will not be iff :,r,-. 2nd EA
+, p, +d+ and ('') are shown with missing parts 5b, and through these notches the listener can grasp the disk 17 with his/her claws and take it out of the magazine 5.However, The notch is quite small, and the listener only grips the outer circumference of the disc 17, so the recording surface of the disc will not be scratched by the listener's claw.

Thereafter, the above operation is repeated depending on the specified disk. Also, in order to replace magazine 5,
When ejecting a magazine, the mounting body 6 in the magazine insertion slot 3a is heard as it is pushed by the ejected magazine.

Next, a description will be given of a means for automatically performing a performance sequence including at least two discs unless a stop command is issued. FIG. 34 shows a case where this self-tlJ playing means is operated manually. First, specify the disc to be played (step S
a) Then, the designated disc is transported onto the turntable 79 (step 521). Then, the performance starts from the beginning of the disc (step 522),
When the performance is finished, the next disc is replaced. When the discs are replaced one after another (step 32G) and the last designated disc is played, the playing starts again from the first disc. If the stop button is pressed during this continuous performance, the performance ends.

It should be noted that FIG. 35 does not show the operation of the automatic performance means when the number of songs is programmed.

FIG. 36 is a diagram illustrating a song head detecting means that sequentially detects the beginning of a famous piece of music recorded on each disk in the magazine 5 and continuously for a plurality of disks. First, when the index scan button (any one of the 26 operation buttons 7 to 10), which is a so-called lock button, is pressed, the button is locked in the pressed state. Then, the number X of the disc to be indexed Suzuki 1 is set to 1, and the beginning of the first track of the first disc is played (steps 341 to S44).In this state, the index skill button is pressed. If this remains, the beginnings of the second and subsequent famous songs on the first disc are played in sequence (from 86). When the opening performance of the famous song recorded on the first disc is completed, the opening performance of the famous song is performed on the second and subsequent discs.

When the first performance of the famous songs on all discs is completed, the normal performance starts from the first disc. Also, if the RELEASE button is pressed during the beginning performance of a famous song, the normal performance is resumed.

FIGS. 37 and 38 are for explaining modifications of the curve head detection means. FIG. 37 shows that when the index scan button is pressed immediately after the beginning of a certain song on a predetermined disc is played, the beginning of the next song starts playing immediately. In addition, FIG. 38 shows that when the index scan button is pressed immediately after the beginning of a certain song on a given disc is played, the beginning of the famous song on this disc is canceled and the first song of each next disc is played. This indicates that the beginnings of the songs will be performed in sequence.

39 to 42 show modified examples of the internal structure of the magazine 5 (4b).

In the magazine 5 shown in FIG. 39, by moving the trigger lever 26 in the direction of the arrow Jh,

The disk 17 is pushed out of the magazine 5.

] In the magazine 5 shown in FIG. 40, when the trigger lever 26 is pushed in the direction of the arrow Jh, the intermediate lever 221 rotates about the bin 221a against the tension of the coil spring 222. As a result, the protruding arm 21, which is biased against the coil link 223, moves once around the bin 21a, and the disk 17 protrudes to the outside of the magazine 5.

In the magazine 5 shown in FIG. 41, by pulling the wire 226 as a trigger lever in the direction of the arrow, the protrusion 7-m 21 swings about the bin 21a against the biasing force of the coil spring 227. The disk 17 is moved out of the magazine 5.

In the magazine 5 shown in FIG.
227 in the direction of the arrow against the f-J '3'' horn of the coil spring 228, the disk 17 is projected out of the magazine 5 by the wire.

It should be noted that the above-mentioned multi-disc player has Jj (4,
As shown in Figure m16, etc., the clamp structure is configured such that the support arm 198 presses and moves the clamp 192 parallel to the disk old holding surface of the turntable 79. It is not limited to. Fourth
Other embodiments of the clamping mechanism are shown in FIGS. 3 and 44. As shown in the figure, the guide shaft 2 extends parallel to the disk supporting surface 79a of the turntable 79.
The support 7-L, 232 is provided with an arm body 233 that carries the decoy 8 on the guide shaft, and a pin 233a at the tip of the arm body in the vertical direction (arrow Z direction and the opposite direction). The sub-arm 235 is swingably mounted in a plane including the direction J3 and rotatably supports the pressing member 192 at its free end. A rack portion 23 is attached to the arm body 233 along the direction of movement ω.
3b is formed, and the 7-arm main body is driven by a drive source including a central part 236 that meshes with this rack portion 233b.

Further, between the arm body 233 and the sub-arm 235, the sub-arm is attached toward the non-ramp position (the position of the sub-arm where the pressing member 192 attached to the sub-arm is sharp from the main surface of the disk 17). A biasing coil spring 237 is interposed. (The nub arm 235 is moved 1':l through the slider 240 by turning an operating lever 239 rotatably provided on the arm body 233 by a pin 239a.

As described in detail above, the multi-disc player according to the present invention includes a housing (2) and a turntable (79), and a performance means provided in the housing. A plurality of disks (17) are arranged and stored in a predetermined mounting section in the housing. 7) - a magazine (5) to be loaded and a magazine valley ejection mechanism (carrying plate 3) for mounting and ejecting the magazine to the mounting portion

In this way, since it is equipped with a magazine attachment/detachment mechanism that automatically attaches and detaches the magazine to and from the player housing, it is easy to operate when attaching and detaching the magazine, and the listening name does not give an annoying feeling at all. be.

Further, in the multi-disc play A7 according to the present invention, the magazine holding part (carrying plate 37 etc.), and a rack part (41d) is formed by rectifying in the mounting direction, and a movable part U that is freely movable in six directions and is elastically connected to the magazine carrier part. (41) and the movable part (44) which engages with the rack part and which drives the movable part (A).In this way,
Costs are reduced because the mounting and removal mechanism is made of members that are relatively slow to manufacture and can be used commercially, such as the movable member forming the rack portion and the tooth width that meshes with the rack portion. There are 41 easy to figure out. Further, since the moving member and the drive fIJ means for driving the moving member also occupy a small space, it is easy to reduce the size of the magazine mounting portion, and thus the disk player as a whole.

Furthermore, since the magazine holding portion and the moving member (41) are elastically aligned, the moving member is not obstructed by the driving means at 686 degrees, and the magazine holding portion is If the stomach is at a height of 11 degrees at rest, the magazine can be installed with high accuracy.
