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).
I). First, the magazine 5 is supported on the support plate 37 shown in FIGS. 7 to 9. In this state, press the magazine 5 a little forcefully. Slide plate 5 provided on the lower surface of carrier plate 37 when magazine 5 is pushed
8 moves backward (in the opposite direction of arrow Y) about 3 m together with the magazine against the biasing force of the spring 59. As a result, the detection switches 63 and 64 are operated, the motor 50 rotates, and the magazine 5 starts moving backward together with the moving member 41 and the support plate 37. When the movable member 41 moves backward by a predetermined distance along the guide shaft 34 and the rear end of the movable member abuts the detection switch 65 and the detection switch operates, the motor 50 stops and the magazine 5 is loaded. is completed (step 82 shown in FIG. 33).

Next, press each operation button l\7 to l\1 shown in Fig. 1.
0, the disc and song to be played are specified by operating a predetermined button (step S3);
1. The II controller f'B (not shown) checks whether the specified disk is stored in the magazine 5 (
Step S4). This confirmation is done by photo sensor 67 or 6.
9. If the specified disk is not in the magazine 5, this will be notified to the listener by an alarm, and the magazine will be ejected to encourage replacement of the magazine 5 (step Ss>. 5, the 11i1J 611 section checks whether another disk is held on the disk holding section 85 (this disk holding section is referred to as a tray in the flowchart). Confirmed by Otohinsa 167 (step S6),
Then, it is confirmed by the photosensors 67 to 69 whether or not there is a storage section in the magazine 5 for storing the other disk (step 87). Disc holding section 85 (tray)
If there is another disc on top of the disc and there is no storage space in the magazine 5 that can accommodate this disc, the magazine is ejected to prompt replacement of the magazine 5, and the listener is notified by an alarm. Step Ss). 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 has a storage section, the other disk will be moved into the magazine 5 by the push-out arm 121 (the 15th
(see figure) (step Ss).

When it is confirmed that there is no other disk on the disk carrier 85, the disk carrier 85 is moved to the storage position of the specified disk 17 (step 5h).
o). The disk holding part 85 is stopped at the specified disk storage position by the photosensors 162 and 212. When the disk holding part 85 is stopped, the actuating rod 112 (see FIG. 15, etc.) is moved to the right (in the direction opposite to the arrow x). This causes the trigger lever 2 in the magazine 5 to
6 (shown in the third figure) is activated, and the disc 17 to be played projects out of the magazine 5 and moves onto the disc carrier 85 (step Sn).

The disk protruding from the magazine 5 is the swinging lever 147.
, 148, etc. (shown in Figure 15), a predetermined position (turntable 79
), and this is the photo sensor 16
7, the motor 108 (see FIG. 10) rotates, the movable body 99 moves forward (in the direction of arrow Y), and the disk carrier 85 carrying the disk is lowered (step 812). In the process of moving the disk carrying pH 85 to its lowest position, the disk 17 on the disk carrying part is moved to the disk carrying surface 7 of the turntable 79.
9a (as shown in Figure 10) (step 513).
).

The forward movement of the movable body 99 continues even after the disk holding part 85 reaches its lowest position, thereby causing the first
The lever member A176 shown in FIG. 0 is rotated counterclockwise in FIG. 10 for the first time. Therefore, the slide plate 179 connected to this lever member A176
moves to the left (in the direction of arrow X), and the clamp mechanism is activated.

The operation of this clamp mechanism will be explained in some 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 rotates by a predetermined angle and presses the pressing member 19.
2 reaches directly above the turntable 79, the adjustment screw 201 provided on the support arm (the arm body 189, which is a component thereof) engages with the bin 202, and the rotation of the support arm is stopped. After this, slide plate 179
is driven further to the left, thereby causing support arm 19
A rotating lever 196, which is a constituent member of 8, rotates about the bin 196a, and therefore, a slide plate 194 connected to the rotating lever moves along the arm body 189. Therefore, as is clear from FIG. 13, the sub-arm 190 swings downward, and the pressing member 192 pushes the disk 1
The disk is clamped against the main surface of 7 (step 514).

On the other hand, as the slide plate 179 moves to the left (in the direction of arrow X), the lever member B183 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
83 bin 183e engages with the interlocking lever 149 to move the interlocking lever forward (in the direction of arrow Y). Therefore,
The swing levers 147 and 148, which were positioning the disk 17 on the disk carrier 85, are disengaged from the outer periphery of the disk 17. Further, by rotating the lever part IB183 in the counterclockwise direction, the protruding part 183C of the lever part pushes the moving plate 170 (shown in the 10th figure) to the left (in the direction of the arrow X). Therefore, the other swinging lever 15 shown in FIG.
5 separates from the outer periphery of the disk. Also, by moving the moving plate 170 to the left, FIGS. 11 and 15
The lifting lever 171 shown in the drawing rotates counterclockwise in FIG. 11 about the bin 171a, thereby causing the disk guide member 86 to swing upward by a predetermined angle. In this way, the disc can be played,
The turntable 79 and carriage 80 (shown in the 10th answer) operate to start playing (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,
The disk 17 is inserted into the magazine 5 from above the disk carrier 85.
The pushing operation is performed by pushing out arm 12 shown in FIG.
It is done by 1. Further, the control section is configured to control the magazine 5.
It is confirmed by the photosensors 67 to 69 whether or not there is a storage section in the magazine 5 for storing the disc to be returned. As shown in FIG.
1 is in the push-out position to push out the disk 17, the tip of the push-out arm seems to come into contact with the magazine 5, but since the magazine 5 has a notch 5b formed in this part, the movement of the push-out arm is limited. will not be hindered. This notch 5 is also shown in Fig. 2 (a>, +d+ and (“)).
b is shown, the listener can grasp the disc 17 with his or her nails through the notch and take it out of the magazine 5. However, the cutout is quite small and the listener can only grasp the outer circumference of the disc 17, so the recording surface of the disc will not be damaged by the listener's fingernails.

Thereafter, the above operation is repeated depending on the specified disk. Also, in order to replace magazine 5,
When ejecting the magazine, the lid 6 of the magazine insertion opening 3a is opened by being pushed by the ejected magazine.

Next, automatic performance means for automatically performing a performance sequence including at least two discs unless a stop command is issued will be described. FIG. 34 shows a case where this automatic performance means is operated manually. First, the disc to be played is specified (step 526).
), the designated disc is conveyed onto the turntable 79 (step 521). Then, the performance starts from the beginning of the disc (step 522), and when the performance ends, it is replaced with the next disc. When the discs are replaced one after another (step 521i) and the [-] of the last designated disc is completed, playback starts again from the first disc. If the En/Hata stop button is pressed during this continuous performance, the performance will end.

Incidentally, FIG. 35 shows the operation of the automatic performance means when the number of songs is programmed.

FIG. 36 is a diagram illustrating a track head detecting means that sequentially and continuously detects the track start of each side recorded on each disc in the magazine 5 for a plurality of discs. First, when the index button (any one of the operation button groups 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 index scanned is set to 1, and the beginning of the first track on the first disc is played (
Steps 541-844>. If the index scan button is held down in this state, the beginnings of the six songs starting from the second song on the first disc will be played in sequence (Sas~
). When the first performances of the six songs recorded on the first disc are completed, the first performances of the six songs recorded on the second and subsequent discs are performed.

When the beginning performances of the six songs on all discs are completed, normal performance starts from the first disc. Also, 6
If the RELEASE button is pressed during the PIJ Hata at the beginning of the song, the normal performance will be 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 immediately starts playing. Further, FIG. 38 shows that when the index scan button is pressed immediately after the beginning of a song on a given disc is played, the beginning performance of the six songs on this disc is canceled and the beginning of the six songs on the next disc is canceled. 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. FIG.

In the magazine 5 shown in FIG. 39, when the trigger lever 26 is pushed in the direction of arrow J, the protruding arm 21 resists the biasing force of the coil spring 29 to

Another embodiment of the clamping mechanism is shown in FIGS. 43 and 44. As shown in the figure, a guide shaft 231 is provided that extends parallel to the disk supporting surface 79a of the turntable 79, and the support arm 232 includes an arm body 233 that slides on the guide shaft, and an arm body 233 that slides on the guide shaft. A sub-arm 235 is attached to the tip of the sub-arm 235 via a bottle 233a so as to be swingable in a plane including the up-down direction (the two directions of the arrows and the opposite direction), and the sub-arm 235 rotatably supports the pressing member 192 at its free end. Become. A rack portion 233b is formed in the arm body 233 along the direction of movement thereof, and the arm body is driven by a drive source including a gear 236 that meshes with the rack portion 233b.

Further, between the arm body 233 and the sub-arm 235, the sub-arm is biased toward the non-clamped position (a position of the sub-arm where the suppressing member 192 attached to the sub-arm separates from the main surface of the disk 17). A coil spring 237 is interposed. The sub-arm 235 is operated by rotating an operating lever 239 rotatably provided on the arm body 233 by a pin 239a.
It is made to swing via a slider 240.
