And a tune head detecting means for sequentially detecting the tune head of each tune recorded on the disc and continuously for a plurality of (for example, three) discs.

Next, the operation of the multi-disc player having the above-described configuration will be briefly described along the performance procedure with reference to FIGS. 33 to 38.

First, as shown in FIG. 1, the magazine 5 is inserted from the magazine insertion slot 3a (step S1 in FIG. 33). Then, first, the magazine 5 is supported on the supporting plate 37 shown in FIGS. 7 to 9. In this state, the magazine 5 is pushed slightly. When the magazine 5 is pressed, the slide plate 58 provided on the lower surface of the support plate 37 is moved backward by about 3 mm together with the magazine against the urging force of the coil spring 59 (in the direction opposite to the arrow Y).
Go to 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 holding plate 37. The moving member 41 moves rearward by a predetermined distance along the guide shaft 34, and the rear end of the moving member contacts the detection switch 65. When the detection switch is operated, the motor 50 stops and the magazine 5 is mounted. Is completed (step S2 shown in FIG. 33).

Next, when a predetermined button among the operation buttons 7 to 10 shown in FIG. 1 is operated to specify a disk and a music to be played (step S3), the control unit (FIG. (Not shown) confirms whether or not the designated disk is stored in the magazine 5 (step S4). This confirmation is performed by the photo sensors 67 to 69. If the specified disk is not in the magazine 5, this is notified to the listener by an alarm, and the magazine is ejected to prompt the exchange of the magazine 5 (step S5). When it is confirmed that the specified disk is stored in the magazine 5, the control unit sets another disk on the disk holding unit 85 (this disk is called a tray in the flowchart). It is confirmed by the photosensor 167 whether the disc is carried (step S6), and it is confirmed by the photosensors 67 to 69 whether or not a storage section for storing the other disc is in the magazine 5 (step S7). If there is another disk on the disk holder 85 (tray) and there is no storage part capable of storing this disk in the magazine 5, the magazine is ejected to prompt the exchange of the magazine 5 and an alarm is issued. The listener is notified (step S8). When a storage portion capable of storing the other disk is provided in the magazine 5 or is replaced with a magazine having a storage portion, the other disk is stored in the magazine 5 by the pushing arm 121 (see FIG. 15). Is performed (step S9).

When it is confirmed that there is no other disk on the disk holder 85, the disk holder 85 is moved to the designated storage position of the disk 17 (step S10). The stop of the disk holder 85 with respect to the designated disk storage position is performed by the photo sensors 162 and 212. When the disc carrier 85 stops, the operating rod 112 (see FIG. 15 and the like) is protruded rightward (in the direction opposite to the arrow X), whereby the trigger lever 26 (third illustration) in the magazine 5 is operated. The disk 17 to be played is projected out of the magazine 5 and moves onto the disk carrier 85 (step S11).

The disk protruding from the magazine 5 is positioned at a predetermined position (directly above the turntable 79) on the disk holder 85 by positioning means comprising swing levers 147, 148, etc. (shown in FIG. 15). When confirmed by the sensor 167, the motor 108
(See FIG. 10), and the moving body 99 is rotated forward (arrow Y).
Direction), and the disk holding unit 8 that holds the disk
5 is lowered (step S12). While the disk carrier 85 moves to its lowermost position, the disk 17 on the disk carrier is placed on the disk carrier surface 79a (shown in FIG. 10) of the turntable 79 (step S13).

The moving body 99 continues to move forward even after the disk holder 85 reaches its re-lowering position, whereby the lever member A176 shown in FIG.
It is first turned counterclockwise in FIG. Therefore, the slide plate 179 connected to the lever member A176 moves to the left (in the direction of the arrow X), and the clamp mechanism is operated.

The operation of this clamp mechanism will be described in some detail. As the slide plate 179 moves to the left (in the direction of the arrow X), first, the support arm 198 of the clamp mechanism 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 the pressing member 192 turns the turntable 7.
9, the adjustment screw 201 provided on the support arm (the arm body 189, which is a component of the support arm) engages the pin 202, and the rotation of the support arm is stopped.
Thereafter, the slide plate 179 is further driven to the left, whereby the rotation lever 196, which is a component of the support arm 198, rotates about the pin 196a,
Therefore, the slide plate 19 connected to the rotating lever
4 moves along the arm body 189. Therefore, the first
As is apparent from FIG. 3, the sub arm 190 swings downward, the pressing member 192 abuts on the main surface of the disk 17, and the disk is clamped (step S14).

On the other hand, the movement of the slide plate 179 to the left (in the direction of the arrow X) causes the lever member B183 shown in FIGS. 10 and 15 to rotate around the pin 183a in the counterclockwise direction in both figures. I do. Then, the first
As is apparent from FIG. 5, the pin 1 of the lever member B183
83e is engaged with the interlock lever 149 to move the interlock lever forward (in the direction of the arrow Y). Therefore, disk 17
The rocking levers 147 and 148, which have been positioned on the disk holder 85, are separated from the outer peripheral portion of the disk 17. Further, the rotation of the lever member B 183 in the counterclockwise direction causes the overhang portion 183 c of the lever member to move the moving plate 1.
Press 70 (10th illustration) to the left (in the direction of arrow X). Therefore, the other swing lever 155 shown in FIG. 15 is separated from the outer peripheral portion of the disk. Also, the moving plate 170
11 to the left, the lifting lever 171 shown in FIGS. 11 and 15 rotates counterclockwise in FIG. 11 around the pin 171a, so that the disc guide member 86 moves upward by a predetermined amount. It can be swung by an angle. Thus, the performance of the disc becomes possible, and the turntable 79 and the carriage 80 (shown in FIG. 10 and the like) operate to start the performance (step S15).

When the performance is completed, the disk is returned to the magazine 5 (step S16). Since the operation of returning the disk to the magazine 5 is performed in substantially the reverse of the above-described disk loading operation, it will be described in detail. Do not. However, the operation of pushing the disk 17 into the magazine 5 from above the disk carrier 85 is performed by the pushing arm 121 shown in FIG. Further, the control unit includes:
It is confirmed by the photosensors 67 to 69 whether or not a storage section for storing a disk to be returned in the magazine 5 is present in the magazine 5. As shown in FIG. 15, when the push-out arm 121 is at the push-out position where the disc 17 is pushed out, the tip of the push-out arm seems to contact the magazine 5, but the magazine 5 has a notch 5 in this portion.
Since b is formed, the operation of the pushing arm is not hindered. 2 (a), 2 (d) and 2 (f) also show this notch 5b, through which the listener can grip the disk 17 with his nails and take it out of the magazine 5. I can do it. However, the notch is quite small, and the listener can grip only the outer peripheral portion of the disk 17, so that the recording surface of the disk is not damaged by the listener's nail.

Thereafter, the above operation is repeated according to the designated disk. When the magazine 5 is ejected in order to exchange the magazine 5, the lid 6 of the magazine insertion opening 3a is opened while being pushed by the magazine to be ejected.

Next, an 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 the automatic performance means is operated manually. First, when a disk to be played is specified (step S20), the specified disk is transported onto the turntable 79 (step S21).
Then, the performance starts from the beginning of the disc (step S2).
2) When the performance ends, the next disk is replaced. When the discs are sequentially exchanged (step S26) and the performance of the last designated disc ends, the performance from the first disc is started again. If the performance stop button is pressed during the continuous performance, the performance ends.

FIG. 35 shows the operation of the automatic performance means when a program is programmed. 36th
The figure illustrates a tune head detecting means for sequentially detecting the tune head of each music recorded on each disk in the magazine 5 and continuously for a plurality of disks. First, when an index scan button (any of the operation button groups 7 to 10), which is a so-called lock button, is pressed, the button is locked in a pressed state. Then, the number X of the disk to be index-scanned is set to 1, and
The head of the first song of the first disc is played (steps S41 to S44). In this state, if the index scan button is kept pressed, the beginning of each of the second and subsequent songs on the first disc is played sequentially (S45). 1
When the beginning of each song recorded on the first disc is completed, the beginning of each song is performed for the second and subsequent discs. When the beginning of each song of all the discs is completed, the normal performance starts from the first disc. Also, when the RELEASE button is pressed during the performance of the beginning of each music piece, the operation shifts to the normal performance.

FIGS. 37 and 38 are diagrams for explaining a modification of the tune detecting means. FIG. 37 shows that if the index scan button is pressed immediately after the beginning of a song on a predetermined disc is played, the beginning of the next song begins. FIG. 38 shows that when the index scan button is pressed immediately after the head of a certain song on a predetermined disc is played, the beginning of each song on this disc is released, and one of the following discs is released. This indicates that the beginning of the tune is performed sequentially.

FIGS. 39 to 42 show a modification 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 projecting arm 21 swings about the pin 21a against the urging force of the coil spring 29, and 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 arrow J, the intermediate lever 221 rotates about the pin 221a against the biasing force of the coil spring 222. As a result, the projecting arm 21 urged by the coil sprinkle 223 swings about the pin 21a, and the disk 17 projects outside the magazine 5.

In the magazine 5 shown in FIG. 41, when the wire 226 as a trigger lever is pulled in the direction of arrow K, the protruding arm 21 is pivoted about the pin 21a against the urging force of the coil spring 227. The disk 17 swings, and the disk 17 projects out of the magazine 5.

In the magazine 5 shown in FIG. 42, by pulling the wire 227 in the direction of arrow K against the urging force of the coil spring 228, the disk 17 is protruded out of the magazine 5 by the wire. .

In the above-described multi-disc player, as shown in FIG. 16 and the like, the clamping mechanism causes the pressing member 192 to move in parallel with the disc holding surface of the turntable 79 by the rotation of the support arm 198. Although it is configured as described above, it is not limited to this configuration.
FIGS. 43 and 44 show another embodiment of the clamp mechanism. As shown, a guide shaft 231 extending parallel to the disk carrying surface 79a of the turntable 79 is provided, and a support arm 232 includes an arm body 233 sliding on the guide shaft, and an arm body 233 of the arm body. Vertical direction (arrow Z) at the tip via pin 233a
And a sub-arm 235 that is swingably mounted in a plane including (in the direction including and in the opposite direction to) and rotatably supports the pressing member 192 at its free end. The arm body 233 has a rack portion 233b formed along the moving direction thereof.
Driven by a drive source that includes a gear 236 that meshes with.
A coil for urging the sub-arm toward the non-clamp position (the position of the sub-arm at which the pressing member 192 attached to the sub-arm is separated from the main surface of the disk 17) is provided between the arm main body 233 and the sub-arm 235. A spring 237 is interposed. The sub arm 235 is
By rotating an operation lever 239 rotatably provided on the arm main body 233 by a pin 239a, the arm 233 is swung via a slider 240.
