After a predetermined period of time has elapsed after the motor 3 stops rotating (ts in FIG. 13), the solenoid 77 of the plunger is energized (16 in FIG. 13). When the solenoid 77 of the plunger is energized and the movable piece 77A is attracted, the arm 102 connected to the movable piece 77A by the pin 77B rotates, and the arm 104 also rotates by the bent piece 102C of the arm 102. do.

When the arm 102 rotates as described above, this arm 1
The pin 102B at the tip of 02 and the stopper piece 101B provided on the intermittent gear 101 are disengaged. Further, when the arm 104 rotates as described above, the engagement between the bin 104A of the arm 104 and the recess 35C of the sliding plate 35 is released.

Pin 104A of arm 104 and recess 35C of sliding plate 35
When the engagement is released, the biasing force of the spring 36 (the upper sliding plate 35 slides a little. Therefore, it is engaged with the elongated hole 35A of this sliding plate 35 via the shaft 101A and the roller 35B. The intermittent gear 101 rotates slightly, and the intermittent gear 101 meshes with the gear portion 100B of the gear 100. After a predetermined time elapses after the plunger 77 is energized, the motor 52
A current is supplied to the motor 52, and the motor 52 starts rotating in a predetermined direction (t7 in FIG. 13).

When the motor 52 rotates, the rotational driving force of the motor 52 is transmitted to the worm gear 53, the gear 54, the gear 55, and the gear 56.
, is transmitted to the intermittent gear 101 via the gear 100, and the intermittent gear 1 old rotates. When the intermittent gear 101 rotates, the sliding plate 35 that engages with the shaft 101A of the intermittent gear 101 slides, and the drive piece 37 attached to the sliding plate 35 rotates one of the rotating levers 153 of the magazine. Push to rotate this rotation lever 153. When the rotating lever 153 rotates, the disk 159 stored in the magazine is pushed by the rotating lever 153, and the disk 159 is pushed out.

Further, the rotational driving force of the motor 52 is transmitted to the gear 80A via the gear 57, and the gear 100, the gear 99,
Since it is transmitted to the gear 44A via the gear 49, the roller 81, the driven rollers 65A, 65B, and the roller 4
5. The driven rollers 43A and 48B rotate. Therefore, the disk 159 pushed out from the magazine first passes through the rotating roller 45 and the driven rollers 48A and 48.
The roller 81 is held between the rotating roller 81 and the driven rollers 65A and 55B and transferred. During the transfer of the disk 169, the light emitting element 9
The light emitted from the light emitting element 97A toward the light receiving element 96A is blocked by the disk 159 to which it is transferred (tS in FIG. 13), and the light emitted from the light emitting element 97B toward the light receiving element 96B is further transferred to the disk 159. (first
t9 in Figure 3). When the disk 159 is further transferred,
Disk 15 between light emitting element 97A and light receiving element 96A
9, the light is no longer blocked (Ha in FIG. 13), and it is detected that the disk 159 has been moved to a predetermined position. t
After a predetermined time from lo, the current to the plunger solenoid 77 is cut off (tll in FIG. 13). When the power to the solenoid 77 is cut off, the slider 78 moves to the arrow
move in the direction. Therefore, the projecting piece 78 of this slider 78
The gear part 62A of the rotating plate 62, which had been pulled by B and was prohibited from meshing with the gear part 57B of the gear 57, meshes with the rotating gear part 57B of the gear 57, and the rotating plate 62 is prevented from rotating. do. At this time, the bin drive plate 58 also rotates.

As mentioned above, the rotary plate 6 is rotated by the rotational driving force of the motor 52.
2 rotates, the drive pin 68B of the roller support plate 63 inserted into the hole of the rotary plate 62 is pushed downward by the rotary plate 62. Therefore, the roller support plate 63 is attached to the bin 53A.
, rotates around 63B as a fulcrum. Roller support plate 63
When the rollers rotate, the driven rollers 65A and 65B supported by the roller support plate 63 also move downward. Therefore, the disk 159 moves downward, and the center hole of the disk 159 fits into the protrusion of the turntable 88. Further, when the roller support plate 63 rotates, the micro switch 97C is turned on by the roller support plate 63 (t in FIG. 12).
ll) Drive pins 53A, 6 of the roller support plate 63
3B are inserted into the inclined cam holes 71A and 71B of the sliders 70A and 70B, respectively, so when the drive pins 68A and 68B of the roller support plate 63 move downward, the slider 70A is driven by the drive pins 68A and 68B. , 70B slides in the direction of arrow X. Further, the slider 82 connected to the slider 70B via a connecting arm 83 slides in the direction of arrow X. When the sliders 70A, 70B and the slider 82 slide in the arrow y and X directions, these sliders 7
The substrate 84, whose position was restricted by being clamped by the tip clamping portions of the 0A70B and 82, is movably supported by the oil-filled damper 85. Also, the arm 74 is the slider 7
Since the arm 72 is connected to the slider 70B via the bottle 72 installed in the 0B, when the slider 70B slides in the direction of the arrow X, the arm 72 rotates clockwise. The arm 74 is for regulating the rotation of the clamp support plate 92. When the arm 74 rotates clockwise as described above, the clamp support plate 92 is biased by the spring 92A and rotates, and the turntable is rotated. The clamp plate 93 presses the hole edge of the central hole of the disk 159 which is fitted into the protrusion of the disk 159 .

Therefore, the disk 159 is held between the turntable 88 and the clamp plate 93.

In this way, the rotational driving force of the motor 52 increases and the rotating plate 62
When the turntable 88 rotates, the driven rollers 65A and 65B move downward, so that the disk 159 moves downward (two times) and fits into the protrusion of the turntable 88, and the clamp plate 93 moves downward. The disk 169 is held between the clamp plate 93 and the turntable 88, and the board 84 becomes movable.
When C is turned on and a predetermined time elapses, the supply of current to the motor 52 is cut off and the rotation of the motor 52 is stopped (13th
t12 in the figure).

The loading of the disc 169 is thus completed, and the disc 169 is then played back. Reproduction of the disc 169 is performed by rotating the disc 169 by rotating the turntable 88 with the motor 89, and detecting the light emitted from the lens 90 and reflected by the disc 169 via the lens 90.

Next, the operation of ejecting the disc 159 will be explained.

When the reproduction of the disc 159 is completed or in the middle of reproduction and a disc eject is instructed (t13 in FIG. 13), the motor 52 rotates in the opposite direction after a predetermined time (t14 in FIG. 13). When the motor 52 rotates in the reverse direction, the gear 57 rotates, and the pin drive plate 58 rotates together with the gear 57.
The pin 62C of the rotating plate 62 is driven to rotate the rotating plate 62, and the gear portion 62A of the rotating plate 62 is rotated to the gear portion 57 of the gear 57.
Engage with B. Therefore, the rotating plate 62 rotates. When the rotating plate 62 rotates, the rotating plate 62 causes the drive pin 6 to
8B is driven upwards. Therefore, the roller support plate 63
rotates, and the driven rollers 55A and 65B move upward,
The disk 159 is lifted upward and the disk 159 is held between the rotating rollers 81.

Further, when the drive pin 68B is driven upward, the sliders 70A, 70B and the slider 82 move as shown by the arrow x, respectively.
While sliding in the x' direction to restrict the position of the substrate 84, the arm 72 rotates counterclockwise to rotate the clamp support plate 92 upward.

The disk 159 lifted upward by the driven loaves 65A and 65B is transported in the direction of the arrow y by the roller 81 which is rotated by the rotational driving force of the motor 52. Further, the disk 159 is connected to the roller 45 and the driven roller 48, which are rotated by the rotational driving force of the motor 52.
A, 48Bc are clamped and transferred toward the magazine. During this transfer, the light-receiving element 96A is shielded from light by the disk 159 (t16 in FIG. 13), the light-shielding of the light-receiving element 96B is completed (t17 in FIG. 13), and the light-shielding of the light-receiving element 96A is further completed. (t1 in Figure 13
8). When a predetermined period of time has elapsed after the end of the light shielding of the light receiving element 96A is detected, the power to the motor 52 is cut off and the rotation of the motor 52 is stopped (t19 in FIG. 13). The disk 159 is stored in the magazine until the motor 52 stops rotating.

Here, when the playback of another disc is instructed, the motor 3
rotates, the elevating table 21 moves upward, and the magazine moves upward. When the motor 3 rotates, the rotating body 9 also rotates,
A pulse is output from the photocoupler 11. When a predetermined number of pulses outputted from the photocoupler 11 are counted, the rotation of the motor 3 is stopped, and the operation after t6 in FIG. 13 is performed.

When the playback of the disc is completed and the magazine eject switch (not shown) is operated (t 20 in FIG. 13),
The motor 3 is energized and rotates.

Therefore, the lifting platform 21 rises. While the lifting platform 21 is rising, one end of the lock pieces 25A, 25B comes into contact with a cam piece formed on the chassis IA, IB, and the lock pieces 25A, 25B resist the urging force of the springs 27A, 27B. It is rotated to unlock the magazine.

When the elevating table 21 further rises, one end of the lever 30 supported by the elevating table 21 comes into contact with the lever 32 supported by the chassis IA. Therefore, the lever 30 is
1, and the contact portion 30A of the lever 30 moves upward from the surface of the lifting table 21. Therefore, a part of the magazine placed on the lifting table 21 is lifted by the contact portion 30A, and the magazine can be easily taken out from the magazine insertion port 38A. Note that the contact portion 30A of the lever 30
When the magazine is lifted up, the microswitch 31 is turned off (tzt in FIG. 13). Lifting platform 21
When the rises to the top, the micro switch 29 turns on.
Then, the motor 3 stops (122 in FIG. 13).

As described above, in this embodiment, a magazine is moved, and a desired disk stored in the magazine (;
The desired disk is taken out of the magazine by sliding the sliding plate 35, the taken out disk is transferred along the reference plane, and then the disk is clamped on the turntable 88 by the clamp plate 93. The turntable 88 is rotated to read information recorded on the disc, and the disc is transported along a reference plane.
The disk transport mechanism is simplified, and the time it takes to take out the disk from the magazine and clamp it on the turntable 88 and the time it takes to put the disk back into the magazine after reading information can be shortened.

Effects of the Invention According to the present invention, since it is only necessary to transfer the disk from the magazine to the turntable in the horizontal direction, the disk transfer mechanism is simplified and the time required for disk transfer can be shortened.
