The shutter plate 73 and the second shutter plate 78 open outward and are located on both side plates 23a and 23b of the frame 23, as shown by dotted lines and imaginary lines in FIGS. 14 and 22, and the lifter 78 , retaining plate 8B, and retaining box 87,88 are both in the upper position, as shown in FIG. Furthermore, the reset lever 90 is the fourteenth
As shown in the figure, the pressing piece 90a is located on the third side of the magazine storage section.

Therefore, first, hold a disc to be played in your hand and insert it into the slit member 8 of the disc magazine 2, starting from, for example, the top slit 8a. It is inserted while pressing the pressing part 17b of the eject lever 17 with its edge without touching the disk holding part 12.1.
It is stored in the disc storage chamber 11 while being carried by two fists 13. The pressed eject lever 17 rotates clockwise about the support shaft 21 and retreats to the rear plate 5, as shown in FIG. At the same time, the first slide lever 15 is moved to the second slide lever 18A by the engagement pin 17a.
At the same time, the holding lever 18 is slid in the opposite direction to the insertion direction of the disk, and at the same time, the holding lever 18 is pulled and rotated clockwise. Then, the holding lever 18 is pushed by the pressing pin 19 and automatically rotates above a certain rotation angle.

The action is to push the disc in the direction of insertion.

Store the disks one by one from the disk storage chamber 11 to the lowest disk storage chamber 11, and when the storage is finished, place the magazine 2 with the disk insertion side first at the entrance of the magazine storage section 3 and push it. The guide groove 4b provided on the bottom plate 4 of the magazine storage section 3 engages with the guide protrusion 25 provided on the bottom plate 24 of the magazine storage section 3, and the bottom plate 4 pushes the pressing piece 28a of the pressing lever 2B to resist the pulling force of the spring 31. The engaging recess 4C engages the engaging portion 29a of the engaging member 28, so that even if the pressing lever is pressed on the 2nd day, it will not come out and will be inserted as shown in Fig. 22. As shown, it is stored and held within the magazine storage section 3. At the same time, the magazine detection switch 27 is turned on, and storage of the disk magazine 2 is confirmed.

Next, the performance order will be explained. Except for FIG. 13, when a member moves to the left in the figure, it is said to be moving forward or forward, and the opposite is called backward or moving backward. First, When the operation button is turned on and the playing order is determined, the drive motor 40 starts rotating, the rotation shaft 33 rotates, the elevation member 34 is lowered, and the second engagement lever 4B stops when it reaches the position of the lever storage chamber 14 provided corresponding to the disk storage chamber 11 storing the target disk. In this case, the first stage (top stage) of the disc storage chamber 11
If that is selected first, the elevation member will not move. Then the drive motor 58 will start rotating, and at the same time the rack part 50 meshed with the pinion 55 will start rotating.
When the drive plate 50 with d starts moving forward, the other drive plate 51 starts moving backward via the control plate 54 which rotates counterclockwise.

When the drive plate 50 starts moving forward, the engagement plate B7 moves forward together with the engagement plate B7, and its tip engages the engagement protrusion 45a of the first engagement lever 45, as shown in FIG. the entire trigger member 44 in the forward direction while slightly rotating it counterclockwise against the elasticity of the spring 48;
Then, the trigger member 44 moves to the guide protrusion 4Ela,
Since the guide grooves 49b and 44c are fitted into the guide grooves 43a and 43b, they are guided by these and start moving forward. On the other hand, the pressing portion 45c of the first engaging lever 45 rotated counterclockwise pushes the pressure receiving portion 48c of the second engaging lever 46 and rotates it clockwise against the pressing force of the spring 48. Therefore, the engagement protrusion 4fla is engaged with the engagement protrusion 15f of the first slide lever 15 on the magazine 2 side.
Then, the holding lever 17 and the eject lever 17, which are engaged with the pressure receiving protrusion 18b and the engagement pin 17a in the engagement grooves 15d and 15e of the first slide lever 15, are respectively supported. The eject lever 17 rotates counterclockwise around the shafts 21 and 22 as a fulcrum, and the eject lever 17 pushes the edge of the disc with its pressing part 17b and pushes it forward from the disc storage chamber 11 through the slit 8a. is the uppermost disc guide y of the holding box 88
t95 and pushed into the disk holding chambers 87a, 88a of each holding box 87,88. On the other hand,
As the holding lever 18 allows the disk to pass and at the same time changes its rotation angle, the holding lever 18 rapidly rotates to push out the disk due to the elasticity of the suppressing pin 190, and as shown in FIG. Evacuate from the passing orbit.

When the engagement protrusion 15f of the lever 15 is engaged and pushed, the first slide lever 15 engages fJ! 15d,
The holding lever 1B and the eject lever 17, which are engaged with the pressure receiving protrusion 18a and the engagement pin 17a on the 15e, rotate counterclockwise around the support shafts 21 and 22, respectively, and the eject lever 17 is rotated by its suppressing portion 17b. Push the edge of the disk to push it forward from the disk storage chamber 11 through the slit 8a.The pushed out disk is guided by the disk guide groove 85 at the top of the holding box 88, and is placed in each holding box 87.8 days. Disk holding chambers 87a, 8
It is pushed into 8a. On the other hand, the holding lever 1B allows the disk to pass and at the same time changes its rotation angle, so that it rapidly rotates to push out the disk due to the elasticity of the pressing pin 18, and as shown in FIG.
8a is retracted from the path of the outer peripheral edge of the disk.

The drive plate 50 still moves forward, the engagement plate B7 pushes the trigger member 44 via the engagement protrusion 45a of the first engagement lever 45, and the trigger member 44 moves forward as shown in FIG. 2
The engagement protrusion 15f of the first slide lever 15 is pushed through the engagement protrusion 48a of the engagement lever 46.
Since the trigger member 44 is prevented from further advancing by contacting the abutting portion 14a of the trigger member 44, the trigger member 44 is prevented from advancing further via the second engagement lever 46. At the same time, the engagement plate 67 and the first
The engagement between the engagement lever 45 and the engagement protrusion 45a is achieved by the first
The guide protrusion 45b of the engagement lever 45 fits into the bent portion 43d of the guide groove 43b and is removed by rotating counterclockwise, so that the trigger member 44, together with the first and second locking levers 45, 46, is moved by the spring 47. is pulled back to its original position by the traction force. However, the first slide lever 15
remains in the same position, and the eject lever 17,
And the holding lever 18 also remains in the rotated position as shown in FIG.

The drive plate 50 continues to move forward and is stopped by the switch control unit 82b pushing the control piece B3a of the limit switch 63 of the drive motor 59 to turn it off. FIG. 24 shows this state.

As described above, the forward movement of the drive plate 50 simultaneously urges the drive plate 51 to retreat via the control plate 54, and as a result of this action, the control lever 7B released from the pressure by the pressing protrusion 70 of the drive plate 51 is moved by the spring 74. The second shutter plate 78, which is urged to slide inward by The shutter plate 73 also rotates clockwise due to the pulling force of the spring 74, moving the suppressing piece 73a to the central position.

This rotation and sliding of the first shutter plate 73 and the second shutter plate 78 to the center position simultaneously causes the pressing piece 73a to press against the disk pushed out from the magazine 2 as described above.

a, 9f (Press a to open it outward as shown in Fig. 24.The control lever 92.96 is rotated outward or inward by the leaf spring 94.97 depending on the rotation angle. The pressure receiving protrusion 92a of the control lever 82, 9B is biased and the edge of the disk opens outward;
There is no contact with 98a. Further, the control lever 82.96 rotated outward or inward is moved by the leaf spring 94.87.
It is controlled by the system and does not open or close naturally.

When the control lever S2.96 opens outward, the engaging projections 82b, 92c-96b, as shown in FIG.
98c protrudes outward from the holding boxes 87, 88 and is positioned so as to be engageable below the engagement pieces 84a, 84b of the lifter 79.

The movement of the drive plate 50.51 continues, and the guide pins 82a, 82b-8 are placed in the lifting guide grooves B5, H-71, 72.
The lifter 78 into which 3a and 83b are fitted is guided by the lifting guides yt65.66 and 71.72 and lowers.
The engagement projection 9 of the control lever 92.96 projects with its engagement pieces 84a, 84b to the outside of the holding box 87.88.
2b, 92c, 98b, and Sec are locked and lowered together with the holding plate 86 against the pulling force of the tension coil springs 89 and 89.

Then, as shown in FIG. 25, the disc is placed on the turntable lOO in the fixed position, and the lifter 79 is further lowered slightly to move the edge of the disc into the disc holding chamber 8.
7a and 88a, and firmly clamp it to the turntable 100 with the clamp member 79a. At the same time, as shown in FIG. 24, the switch control piece 82b provided on the drive plate 50 presses the control piece C3a of the limit switch 63 of the drive motor 59 to turn it off, so the drive plate 50 stops and at the same time the lifter 78 will also stop. Then, the drive motor 101 is turned on, the turntable 100 begins to rotate, the optical pickup 102 picks up the selected song, and the performance begins.

When the performance ends, the turntable 100 stops, the drive motor 58 is turned on to rotate in the opposite direction, the drive plate 50 now moves backward, and the drive plate 51 starts moving forward via the control plate 54. Then, the lifter 79 starts to rise, the clamp member 7θa releases the clamp on the disk, and then the holding box 87.88 is moved along with the holding plate 88 by the tension coil spring 88.88.
The disc holding chambers 87a, 88a
Return to the original position while keeping the disc inside. Engagement pieces 85a and 85b provided on the lifter 79 are for ensuring that the holding box 87.88 rises more reliably, and when the holding box 87.88 returns to its original position, the recessed hole provided in the drive plate 50 The reset lever 80, in which a pin 90c is inserted into the reset lever 84, rotates clockwise and pushes the edge of the disk toward the magazine 2 with its pressing piece 90a. 1 shutter plate 7
3 is rotated and retracted to the outside, and the second shutter plate 78 is slid and retracted to the outside on the opposite side from the first shutter plate 73 by the pressing protrusion 70 provided on the drive plate 51 and the control lever 76. When the first shear plate 73 and the second shear plate 7B, which do not interfere with the movement of the disk conveyed by the side helical set lever 90, move outward, the control lever 82.9B) pressure receiving part 92d,
913d to rotate counterclockwise and clockwise, respectively, and return the control lever 82.8B to its original position as shown in FIG. Keep that posture stationary.

Slip by the pressing piece 90a of the reset lever 80)8
The disk inserted into the first disk storage chamber ll of the magazine 2 through the eject lever 1 at its edge
7 and rotate it clockwise.

When the eject lever 17 rotates, the first slide lever 15 slides through the retaining pin 17a and attempts to return to its original position, at which time the retaining lever 18 is rotated clockwise. The rotation of the holding lever 18 is timed so as not to block the movement of the inserted disc, and when a certain amount of the disc is inserted, the pressing pin 19 acts to press the disc in the insertion direction. However, after storing the disk, is the disk used as a magazine? This is to hold the drawer so that it cannot easily come out.

After the reset lever 80 returns the disk into the magazine 2, the switch control section θ2a provided on the drive plate 50 switches the control piece 13 of the limit switch 63 of the drive motor 59.
Press 3a to turn it off, so the - cycle operation ends here. The entire apparatus then returns to the state of waiting for the next disc to be played, as shown in FIG. 14 or FIG. 22.

Next, when the disc to be played is selected automatically if the playing order has been set in advance, or by operating the operation dial if not, the drive motor 40 is activated again as described above. After starting the rotation, the elvage electric member 34 of the disc ejecting means is moved up and down, and the first retaining lever 45 and the second engaging lever 4B are stopped at the position of the disc storage chamber 11 containing the target disc. and,
The above-described operation is repeated, and the discs are automatically played one after another.

When the playing of the disc is finished and ejection of the magazine 2 is commanded, the drive motor 40 starts rotating and lowers the elevation member 34 via the rotation shaft 33 as shown in FIG. let Then the stopper plate 3B
The stopper part 36a presses and switches the control piece 38a of the limit switch 38 of the drive motor 40, so that further lowering of the elevation member 34 is prevented, and the drive motor 40 now rotates in the opposite direction and starts again. After the elevation member 34 is raised to the highest stage, it is stopped.

When the elevation member 34 is lowered, as shown in FIG. As the magazine 2 is lowered, the engaging portion 29a that locks the magazine 2 is disengaged from the retaining portion 4c of the magazine 2, and the pressing lever 28, which always presses the magazine 2 in the ejection direction by the spring 31, uses the pressing piece 28a to release the magazine 2. 2 bottom plate 4
Since it is pushed forward, it can be taken out from the magazine storage section 3 by holding it by hand. At the same time, the magazine detection switch 27 is turned off.

When replacing the disk in the magazine 2 that has been taken out in this way, hold the magazine 2 with one hand with the slit member 8 side up, as shown in FIG. When the pressing protrusion 18d of the slide lever 18A or 18B is pressed, this second slide lever IB
A, and the first slide lever 15 engaged with 18B
slide at the same time, eject lever 17 and holding lever 1
8, the disc is inserted into the slit 8 just as the second engagement lever 46 described above would do this in the automatic case.
It will pop out from a, so hold it in your hand and pull it out, then hold the replacement disk in your hand and insert it through the slit 8a from which you just pulled out the disk, and the eject lever 17
rotates clockwise and retracts to receive the disk, and when a certain amount of disks have been inserted, the holding lever 18 acts in the direction of pushing the disk to ensure that the disk is stored in the disk storage chamber 11 of the magazine 2. be done. At this time, the holding lever 18 presses the disk in the insertion direction via the pressure bottle 19, so even if the magazine 2 is turned downward, the disk will not naturally fall from the disk storage chamber 11 through the slit 8a. .

During this f movement, the first slide lever 15 has a smaller movement range than in the automatic case, as shown in FIG. This is to prevent the disc from rotating too much as it does when it is automatic, since it will gain too much momentum and fly out of the pickpocket 7) and 8a. In the automatic case, the first slide lever 15 moves by the length of the elongated holes 15a, 15c into which the second slide levers 16A, 16B (7) vias 18a, 16c are fitted, and the spring 2
0 is the second slide tray/<-18A, 18B is the protrusion 18b
It functions so that it always occupies a fixed position with respect to the first slide lever 15 via. Further, the leaf spring 8b is used to press down the edge of the disk passing through the pickpocket 7) 8a to prevent it from flying out with force.

(Effects) As explained in detail above, according to the present invention, the engaging member provided on the bottom plate of the magazine storage section and rotatably biased in one direction in order to make the magazine engage 1 is connected to the disc ejecting means. Since the equipped elevation member is operated to release the lock from the magazine, it is possible to reliably engage and disengage the magazine 1F with a simple configuration.
