0 when the slide plate 22 (22L, 22R)
The initial position is detected, that is, the initial switch 3
0 is the initial position detection for detecting the initial position of the slide plate 22
It is a means. Therefore, the slide plate 22 (22L, 22L)
The sliding position of R) was detected by the right slide plate 22R.
Sliding of left slide plate 22L with reference to initial position
Pulse from the photosensor 28
It is detected by addition and subtraction by the counter 29,
Depending on the number of pulses, the operation of the disc automatic
Multiple cam modes are set as described in section
It has become. Next, on the right slide plate 22R side, a shear
On the bottom surface 21a of the sheet 21, the base tray 10
And a gear 31 for transmitting the driving force to the sub-tray 11.
The gear 31 is provided from the second motor 33
Is decelerated by the second reduction mechanism 32 to rotate.
Further, it is formed substantially at the center on the bottom surface 21a of the chassis 21.
A pair of cut-and-raised pieces 21a₁, 21a₁The base

(In the direction of the arrow). One end of the switching lever 34 via a shaft 35
On the side, a pin portion 34a faces the left slide plate 22L side.
The pin portion 34a slides
Driving force switching cam groove 22L formed on plate 22L₄Fit into
I agree. At this time, the drive formed on the slide plate 22L
Force switching cam groove 22L₄Is the sliding of the slide plate 22L.
Depending on the position, the lower cam groove and the higher cam groove
It is formed so as to be connected to a plurality of mountain shapes. On the other hand,
A shaft portion 34b is attached to the other end of the bar 34 via the shaft 35.
Protruding toward the bottom surface 21a side of the
The gear 37 is supported by the shaft 34b. this
At this time, the switching lever 34 is located between the chassis 21 and the gear 37.
Gear 37 is moved upward by the compression spring 36 provided at
Has been energized. The switching lever 34 is pivotally supported at the other end.
The gear 37 always meshes with the gear 31 connected to the second motor 33.
Gear 3 is rotated by the switching operation of the switching lever 34.
7 moves up and down along the gear 31. Then, the pin portion 34a of the switching lever 34
Driving force switching function according to the sliding position of the slide plate 22L.
Groove 22L₄When engaging with a cam groove with a low
The other end of the exchange lever 34 is inverted via a shaft 35 to
37 is moved upward, and the gear 3

The first gear 42 for driving the base tray is meshed with the first gear. This
Here, the first gear 42 for driving the base tray is mounted on the chassis 21.
The shaft is mounted below the shaft 40 implanted in the
Pressure between the base 21 and the first gear 42 for driving the base tray.
A compression spring 41 is provided, and above the shaft 40
The first for driving the base tray through the urging force of the compression spring 41
Second gear for driving the base tray that rotates integrally with the gear 42
Since the shaft 43 is mounted on the shaft, the driving force of the second motor 33 is
Gear 31, gear 37, first gear 4 for driving the base tray
2, transmitted in the order of the base tray driving second gear 43
It has become. At this time, the first gear 42 for driving the base tray
And the second gear 43 for driving the base tray up and down on the shaft 40.
The reason is that the base tray 10 is manually moved
Only the base tray driving second gear 43
When the base tray 10 is automatically moved
The first and second gears for driving the base tray are connected to the drive source.
This is for the purpose of rotating the members 42 and 43 integrally. Therefore, it is formed on the left slide plate 22L.
Driving force switching cam groove 22L₄And the constituent member 31
