When the front P cam 171 rotates, the rotation/movement plate 08) starts rotating downward around the shaft (19i), and the drive rope 20) moves in the direction of loosening. Accordingly, the fixing plate (211) and the disk holding bins (6) and (7) start descending. Naturally, the disk holding bins (61 and (7) (5) also descends.

As mentioned above, the closing action during boulder and Tinuku (5)
Since the lowering of the TINUK (5) 1 starts at the same time, the TINUK (5) 1 gradually rotates to the normal mounting position.

Next, the detailed operation when installing the disk will be explained using Fig. 3.0 When the Tinuku (5) is inserted in the standby state as shown in Fig. 6 (A), the lower end of the disk (5) When it comes into contact with the disc holding bin (7j), the sensing means is actuated to start the device, and the rotation of the holder (1) in the direction of arrow B and the lowering of the tinuk holding bin (7) begin.

Then, when the holder (1) has rotated to about 11 degrees,
Figure 6 C) As shown in Vrc, the Tinuku holding bottle 1
7) is lowered to the predetermined position shown in the figure, and the turntable (23.
The center shaft 12411C of the disk (5) can be fitted into the center hole of the disk (5).

Then, when the breast and boulder 111 shown in Figure (c) were further moved by IMI, and the center shaft (241) of the turntable (231) was placed in the hole of the tinuk (15), Holder (1) (with self-targeted disc holder (1) placed west 1).

A magnet is placed on the central axis 1 of the turntable blade 1, and a grinding stone 9 is pulled so that the tip presser presses the outside 51 of the turntable against the turntable. . In the third condition (C), the Tinuku (5) is installed in the playing start state, but the Tinuku holding bottle 17. Since it is in contact with the lower end VCW of the disk [5, it is difficult to rotate the disk (51) once in this state. As shown in Fig. 3), the Tinuku holding bottle (7) is further lowered, and the Tinuku (5) rotates only after the contact between the Tinuku (5) and the Tinuku holding bottle (71) is released. Insert the disc holding bin (7

7+ with a second drive means for lowering the disc holding bins (6) and (7) 9? This can be achieved by appropriately setting the gear ratio, etc. Note that in FIG. 6, hatching indicating the cross section is omitted.

A pair of disk holding bins (61 and 71 are fixed to a fixing plate (211) as shown in FIG. The holding bins (6) and (7) are installed and fixed. The front WE' fixing plate! 21) is a single-shaped metal fitting □□□
; is loosely connected to the front-mounted metal fitting);
One end of the F-robe is fixed to the totomo on which the microswitch (which serves as the detection means) is installed and fixed, and one end of the F-robe is connected to the chassis and the other end of the bent spring is connected. 1 round.

Sweet, Tinuku is in the closet? - Suddenly, the lower end of the disk comes into contact with the disk holding bins (6) and (7), and due to Dinuk's downward speed and its own weight, the fixing plate (2)
]) is lowered relative to the 1-shaped metal plate (26'), turning on the micro-sinch a). The contact point (27a) of the front e micro switch is biased upward by a spring disposed inside, and the fixing plate (211) is held in place by the contact point, or the contact point (27a) is kept in place by the contact point. By strongly inserting it, a force is generated that resists the biasing force of the spring of the aforementioned microswitch I27), and the fixing plate (21) descends to turn on the microswitch I27).

After the disk is inserted, there is no force to resist the biasing force of the spring, and the biasing force of the spring causes the contact point 1 of the microswitch and the fixing plate c! 1) returns to its original position. Therefore, a pulse-like signal is generated from the microswitch τ1 to indicate that a disk has been inserted, and in response to this signal, a separate circuit C (see Figure 1) is activated. Indicates that +1 is also used; motor (8
2 starts operation, and the device starts operating. (When the motor (8) operates and the whistle 2' pigeon mechanism works, the distance lobe prisoner moves once in the direction of arrow C, and the 1 and 1-shaped metal fittings α1 of the fixed plate are connected to the springs (supports). It starts to descend according to the elasticity.For this purpose, the disc holding bins (6) and (71) are provided in the halter (1), and the grooves j and t.
Lower the machine and bring the disc to the device position.

Note that j311 is an M-shaped guide bin attached to the fixed plate (21:).

2.-The disc loading device according to the invention can also be used as a disc ejecting device.
When ejecting a disc in the device state as in (i''η), the drive motor f81 i, which is capable of reversible operation, is used.
For the front 3 hills,
l Rotate the motor (8) in the opposite direction. Then, the second
．． In response to the operation of the drive means, the disk holding pins (61 and (7) come into contact with the lower end of the disk (51) as shown in FIG. At the beginning of the process, the opening of the holder and the lifting of the disk holding pins (6) and (7) proceed simultaneously, and the state shown in Fig. 6 (b) is changed to the state shown in Fig. 3 (b). Therefore, from the state shown in Figure 3 (a), the listener should either pull out the disc (51) and attach another disc, or press the upper end of the disc (51) to activate the detection means. I'm going to make it work, right? The voice disk =t
