The magazine M is stored, and the elevating block 45 moves to the lowest point to eject the magazine M. Only after the lock lever 57 is unlocked, the housing 200 is unlocked. can be taken out from the mother case 210.

[0026] (Magazine loading and ejecting operations) As mentioned above, loading and ejecting the magazine M is carried out when the movable table A is on top. The clamp arm 110 has been drawn into the case 21 of the unit C and is descending. This is performed while being stored in a storage area that overlaps with the reproduction unit F at the top. The movement of pulling the moving table A into the upper unit C is performed by the motor of the lower unit E. This is done by m3. This motor m3 transmits the drive gear through the gear group 125. When the wheels 128a and 128b are driven counterclockwise, the case 21 of the upper unit C The feed gear 24 provided on the side plate 21a of the moving table A is driven clockwise. The rack on the side plate 11b is driven, and the movable table A is pulled into the upper unit C. be included. At this time, the clamp arm 110 is lowered by the motor m3, and the clamp arm 110 is lowered by the motor m3. The moving table A is housed on the reproduction unit F from which the moving table 110 is lowered. this condition Magazine M is inserted in this state. Magazine M is inserted into the magazine insertion hole 20 of the nose 201. 2, push the door 19 of the moving table A and move the bottom plate 11a and the guide plate 11c. inserted between. When the magazine M is inserted, the lock pin 12 locks the magazine. M is locked. From then on, until it is ejected, the moving table A and magazine M will be Works as one.

[0027] The eject operation to eject magazine M is performed on moving table A. When the magazine M held by this is pulled above the playback unit F, It is possible. When the eject command is issued, the motor m of the selection drive mechanism B shown in FIG. 1, the worm wheel 51 is driven and the drive screw 49 integrated with the worm wheel 51 is driven. The elevator block 45 is driven to lower. When the lifting block 45 descends, The ejection/insertion roller 41 that moves up and down together with the elevating block 45 is located at the base indicated by (0) in FIG. Descend to the height corresponding to the position. In this position, the robot moves up and down together with the lifting block 45. The drive arm 86 is connected to a lock lever provided under the bottom plate 11a of the movable table A. -13 facing the side 13a. In this state, the motor provided in selection drive mechanism B gear 62, gears 63, 64, 71, 72, and gear 73. When the switching gear 74 is driven, the drive arm 86 is driven by the cam 75, and the lock is rotated. Clever 13 is driven, the lock by lock pin 12 is released, and magazine M is discharged. At this time, as shown in FIG. The lever 57 is driven counterclockwise, the lock protrusion 57b is retracted, and the housing 200 As mentioned above, the lock is released.

[0028] (performance movement) The loading and ejecting operations of the magazine M are performed when the magazine M is pulled as described above. The playing operation of disk D is also performed with the magazine M loaded in the upper unit. This is done while it is retracted into the knit C. At this time, pull from magazine M. The ejected disc D is sandwiched between the turntable 106 and the clamper 115. held. and a storage area located above the descending clamp arm 110. A moving table A and a magazine M are stored in the area. In this playing operation state, the selection drive mechanism B (Fig. The drive screw 49 is driven by the motor m1 (see 3), and the lifting block 45 rises, and the ejection/insertion roller 41 is at a position above the original position (0) shown in FIG. In other words, it has moved to a position above the first selected position (1). The drive shown in Figure 3 The arm 86 also rises together with the lifting block 45 and moves to a position where it is removed from the lock lever 13. It's moving. In this way, during the performance operation, the lifting block 45 rises and the swinging lever 4 2 is moving clockwise, the lock lever 57 shown in FIG. status remains maintained.

[0029] (Disk exchange operation) The operation of changing the disc from the playing state will be explained below. In the disk exchange operation, first, the motor m3 of the lower unit E is driven. this The driving force is transmitted to transmission drive gears 128a and 128b by a gear group 125 shown in FIG. and the feed gear 24 provided on the side plate 21a of the upper unit C and the other side. The feed gear provided on the plate 21e is driven counterclockwise to the side of the moving table A. Power is applied to the rack provided on the plate 11b, and the movable table A moves to the upper unit. It protrudes from C (see Figure 2). At this time, magazine M is held on moving table A. Since the door 19 also rotates upward and protrudes, the user cannot eject the door 19. It is possible to recognize that the magazine M is not loaded, but that a disk exchange operation is in progress. The transmission drive gears 128a and 128b are driven by the motor m3 of the lower unit E. When the movable table A protrudes, the clamp is clamped by the driving force of the same motor m3. Arm 110 is raised in a substantially horizontal position. Therefore, on the turntable 106 The clamp on disk D is released. This lifting of the clamp arm 110 and the above-mentioned The protruding operation of the moving table A is just as the magazine M etc. is removed from above the disk D. This is the timing when the lifting of the clamp arm 110 is completed. Also When the pump arm 110 rises, the lower driven roller 31 moves from the slide of the roller holder 32. The disk D is rotated and lifted by the pulling force, and the left end of the disk D is ejected and inserted. It is in a state where it is held between the roller 41 and the lower driven roller 31.

[0030] In this way, the moving table A protrudes from the upper unit C, and the clamp arm The disk is replaced while 110 is raised. First, the selection drive shown in Figure 5 The drive screw 49 is driven by the motor m1 of mechanism B, and the lifting block 45 is moved. The ejection/insertion roller 41 is raised and lowered via the roller connection lever 47, and as shown in FIG. to move it to one of the selected positions shown in (1) to (3). This is mentioned above It is controlled by detecting the rotation speed of the sea urchin detection rotating body 55 with an optical detector 56. It will be done. For example, the disc D that was previously clamped on the turntable 106 When the place to return is the disk storage space S2 in the second stage of the magazine M, The ejection/insertion roller 41 is in the second stage selection position shown in (2), and this roller 41 and the lower side The end of the unclamped disk D is held by the driven roller 31, and this Disk D faces the front of the space S2. Ejection insertion roller 41 and When the control of the selection position of the lower driven roller 31 is completed, the selection drive mechanism B shown in FIG. motor m2 is driven, and the ejection/insertion roller 41 is driven clockwise via the gear group. and the disk D is returned to the space S2.

[0031] Next, when pulling out a new disk, raise and lower the lifting block 45 using m1. The ejection/insertion roller 41 and lower driven roller 31 are shown in (1) to (3). Move to any selected position. Then, the switching lever (not shown) is activated by the cam 75. The drive arm 86 operates a discharge member (not shown) provided on the magazine M. , any one of the movable plates 4, 5, 6 in the magazine M rotates to open the spaces S1, S2, A disk D provided inside one of the S3 protrudes from the opening 3 of the magazine M. do. Then, the discharge/insertion roller 41 is driven counterclockwise by the motor m2. The selected disc D is connected to the turntable 106 in the disc playback unit F. It is sent between the lamp 115 and the lamp 115. When the withdrawal of the disk D is completed, the motor m1 shown in FIG. 5 is driven again. The lifting block 45 is lowered, and the ejection/insertion roller 41 and lower driven roller 31 are in their original position. The end of the disk D that has descended to position (0) and is still held between rollers 41 and 31 is lowered onto the turntable 106. Then disk D is clamped playback is performed.

[0032] As mentioned above, during this exchange operation, the moving table A and the mechanism base 40 move. Therefore, the bent piece 42a of the swing lever 42 shown in FIG. 7 comes off the arm 57c, Therefore, the locked state by the lock lever 57 shown in FIG. 7 remains maintained. In the above embodiment, three disks D are stored in the magazine M. However, any number of discs can be stored, and the disc D can be stored in the magazine M. may be stored. In the embodiment shown in FIGS. 1 and 2, the fitting protrusion 204a of the handle 204 is The handle is fitted into the handle lock hole 211 of the user case 210. Without locking by fitting, the lock protrusion 57b of the lock lever 57 shown in FIG. Therefore, the housing 200 may be locked to the mother case 210. Further, the lock lever 57 may be protruded from the housing by a mechanism such as a solenoid or the like. It may be made to regress.
