The motor 50 rotates, and the magazine 5 starts moving backward together with the moving member 41 and the support plate 37. The moving member 41 moves backward by a predetermined distance along the guide shaft 34, and the rear end of the moving member abuts the detection switch 65,
When the detection switch is operated, the motor 5o is stopped, and the mounting of the magazine 5 is completed (step 82 shown in FIG. 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 83), the control section (not shown) determines whether or not the designated disc is stored in the magazine 5. (Step S4)
). This confirmation is performed by photosensors 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 replacement of the magazine 5 (step Ss). When it is confirmed that the specified disk is stored in the magazine 5, the control section controls whether another disk is supported on the disk holding section 85 (this disk holding section is called a tray in the flowchart). It is confirmed by the photosensor 167 whether the other disc is stored (step S6), and whether or not there is a storage section in the magazine 5 for storing the other disk is confirmed by the photosensors 67 to 69 (step 87). If there is another disk on the disk holding section 85 (tray) and there is no storage section in the magazine 5 that can accommodate this disk, the magazine is ejected to prompt replacement of the magazine 5, and an alarm is activated. The listener is informed (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 stored in the magazine 5 by the push-out arm 121 (see Fig. 15). (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 designated disk 17 (step 5h).
o). The disk holding part 85 is stopped at the designated disk storage position by photo sensors 162 and 212. When the disk holding part 85 is stopped, the actuating rod 112 (see FIG. 15, etc.) is moved to the right (counter to the direction of arrow X). ), whereby the trigger lever 26 (shown in the third figure) in the magazine 5 is actuated, and the disc 17 to be played is projected out of the magazine 5 and moved onto the disc holder 85 (step S++).

The disk protruding from the magazine 5 is the swinging lever 147.
．． 148 (shown in FIG. 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 512). In the process of the disk holder 85 moving to its lowest position, the disk 17 on the disk holder 85 moves to the disk holder 79 of the turntable 79.
a (Fig. 10) is placed on (Stelaph S day).

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
The rotating lever 196, which is a constituent member of 8, rotates around the bin 196a, and therefore, the slide plate 194 connected to the 1-shifting lever moves along the arm body 189. Therefore, from FIG. As is clear, the sub-arm 190 swings downward, the pressing member 192 comes into contact with the main surface of the disk 17, and the disk is clamped (step 5I4).

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 holder 85, are disengaged from the outer periphery of the disk 17. Furthermore, as the lever member 8183 rotates counterclockwise, the protruding portion 183c of the lever member pushes the moving plate 170 (shown in the 10th figure) to the left (in the direction of 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 figure 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 (see FIG. 10) operate to start playing (step S?S).

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 operation of pushing the disk 17 into the magazine 5 from above the disk holder 85 is carried out by the pushing arm 121 shown in FIG.
done by. Further, the control section is configured such that the storage section for storing the disks to be returned into the magazine 5 is
The photosensors 67 to 69 confirm whether or not there is one inside. As shown in FIG.
When the push-out arm 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. not be hindered. This notch 5b is also shown in FIG. 2(a), (Small and +f+), and through this notch the listener can grasp the disc 17 with his or her nails and take it out of the magazine 5. The notch is quite small, and the listener can only grasp the outer periphery 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 A body 6 of the magazine insertion opening 3a is opened by being pushed by the ejected magazine.

Next, an explanation will be given of an automatic performance means that automatically performs a performance sequence including at least two discs unless a stop command is issued. FIG. 34 shows the case where this automatic performance means is operated manually. First, the disc to be played is specified (step Sa)
, this specified disc will be placed on turntable 7.
9 (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 disks are replaced one after another (step 526) and the last specified disk is played, the playback starts again from the first disk. If the stop button is pressed during this continuous performance, the performance ends.

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 song head detecting means for sequentially detecting the song start of each city 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 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 841-544). If the index scan button is held down in this state, the beginnings of songs for each city starting from the second song on the first disc will be played in sequence (Sas~
). When the opening performance of each city recorded on the first disc is completed, the opening performance of each city is performed on the second and subsequent discs.

When the beginning performance of each city 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 each city's 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 immediately starts playing. In addition, Fig. 38 shows that by pressing the index scan button immediately after the beginning of a song on a given disc is played, the beginning of the song for each city on this disc is canceled and the first song on the 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. 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
The disk 17 is pushed out of the magazine 5 by swinging about 1a.

In the magazine 5 shown in FIG. 40, when the trigger lever 26 is pushed in the direction of the arrow J, the intermediate lever 221 rotates about the pin 221a against the tension of the coil spring 222, thereby causing the coil spring link. The protruding arm 21, which is biased by
protrudes to the outside of the magazine 5.

Furthermore, in the magazine 5 shown in FIG. 41, by pulling the wire 226 as a trigger lever in the direction of the arrow, the protruding arm 21 swings about the bin 21a against the biasing force of the coil spring 227. , the disk 17 protrudes outside the magazine 5.

In the magazine 5 shown in FIG.
7 in the direction of the arrow against the biasing force of the coil spring 228, the disk 17 is projected out of the magazine 5 by the wire.

In the above-mentioned multi-disc player, as shown in FIG. However, it is not limited to this configuration. 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 distal end of the sub-arm 235 via a bottle 233a so as to be swingable in a plane including the up-down direction (arrow Z direction and the opposite direction thereof), and the free end of the sub-arm 235 rotatably supports the pressing member 192. 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 engages with the rack portion 233b.

Further, between the arm body 233 and the sub-arm 235, there is a coil that urges the sub-arm toward a non-clamping position (a position of the sub-arm where the pressing member 192 attached to the sub-arm separates from the main surface of the disk 17). A spring 237 is interposed. The sub arm 235 is
By rotating an operating lever 239 rotatably provided on the arm body 233 by a pin 239a, the arm body 233 is caused to swing via a slider 240.

11 11 As detailed above, the multi-disc player according to the present invention includes a playing means including a turntable (79) and a pickup, a magazine (5) that sequentially arranges and stores a plurality of discs (17), a disc transport mechanism that sequentially selects arbitrary discs in the magazine, transports them onto the disc support surface of the turntable, and returns the discs from the disc support surface into the magazine; and the playing means and the disc transport mechanism. The controller includes an automatic performance means for automatically performing a performance sequence including a small number of discs (including at least two discs) unless a stop command is issued.

Therefore, automatic performance over a long period of time, such as playing background music, is possible.
