In addition, as shown in Figure 6, since the motor 69 that will drive gear wheel 61 be arranged on the 2nd mobile chassis 12 following with same area above-mentioned spindle drive motor 14, because of unnecessary special arrangements are the space that this motor 69 is set, thereby help the thin typeization of device.Again because pinion wheel 62a, gear 62b and each driven wheel 65a, 67a are located in the trigonum E of periphery outside of the dish D that selections, the B of playback portion take out, for the flat shape increase that these gears do not make device yet is set.
On above-mentioned gear wheel 61, form cam path 61a, the follower peg 71 that is arranged on the lever portion of above-mentioned trace 51 can be inserted in this cam path 61a with being free to slide.
On the 1st mobile chassis 11, establish and take out lever 72.But this is taken out lever 72 free rotary ground supportings on the 1st mobile chassis 11 with axle 73.Take out formation cam path 72a on the lever 72 at this.On gear wheel 61, establish sliding pin 74, this sliding pin 74 can be inserted in the cam path 72a with being free to slide.Form linear sliding tray 11e on the 1st mobile chassis 11, will take out hook 75 can be bearing in this sliding tray 11e with being free to slide.On taking out hook 75, this forms pin 75a.On the top of above-mentioned taking-up lever 72, form slotted hole 72b, above-mentioned pin 75a is inserted in this slotted hole 72b,, make and take out the rotational trajectory rotation that lever 72 is followed sliding pin 74, taking-up hook 75 is moved along above-mentioned sliding tray 11e when driving gear wheel 61.By the rotation of gear wheel 61, make taking-up hook 75 slide, move between position shown in Figure 9, to the diagram right the pallet T that in tray salver M, selects in the position from Fig. 8
1Select to dish, the dish clamped position of playback portion takes out.
Fig. 5 amplifies the shape that is illustrated in cam path 61a that forms on the gear wheel 61 and the cam path 72a that forms on taking-up lever 72.
The cam path 61a that forms on gear wheel 61 has the 1st curve part (a) and the 2nd curve part (b).Have arc sections (c) and line part (d) at the cam path 72a that takes out formation on the lever 72.When being rotated in a clockwise direction from Fig. 5 and phase place shown in Figure 8, gear wheel 61 becomes phase place shown in Figure 9, drive taking-up lever 72 by sliding pin 74 to clockwise direction, taking-up hook 75 is moved when right-hand member shown in Figure 9, this moment, becoming the axle that the arc sections (c) that makes cam path 72a is positioned at gear wheel 61 60 is on the arc track at center.
At the state of Fig. 5, make gear wheel 61 along counter rotation, make by sliding pin 74 and take out lever 72 and move along counter-clockwise direction.In addition, make the follower peg 71 that is arranged on the trace 51 be positioned at the end of the 1st curve part (a) of cam path 61a.At this moment, trace is rotated to clockwise direction, therefore, position and lock plate 41 (1) direction in Fig. 8 is moved, the position and lock plate 45 symmetrical with it moved to (4) direction by this trace 51.
When driving gear wheel 61 from state shown in Figure 5 to clockwise direction sliding pin 74 is slided in cam path 72a with motor 69 (referring to Fig. 6), driving taking-up lever 72 to clockwise direction in view of the above makes the sliding trace of sliding pin 74 in cam path 72a of this moment move to the position of groove terminal point (ⅱ) from the position of the starting point (ⅰ) of groove, and then return at line part (d), return (ⅲ) position of major trough central authorities.Slide at sliding pin 74 during the position of (ⅲ), taking out the right-hand member that the sliding tray 11e of hook 75 along formation on the 1st mobile chassis 11 is transferred to Fig. 8, can be with taking out hook 75 with the pallet T in the tray salver M
1Take out fully.Yet this moment, make follower peg 71 only move to terminal point (ⅴ) position of the 1st curve part (a) from groove starting point (ⅳ) position.Because during follower peg 71 moves to (ⅴ) position from (ⅳ) position, only drive trace 51 to anti-clockwise direction slightly, make position and lock plate 45 to the amount of movement of (1) direction with make position and lock plate 41 very little to the amount of movement of (4) direction, at this moment, owing to the lock slots 41c among Fig. 3 is not extracted from locking plate 12c, will not lock recess 41h equally and extract, and in addition, spacer 41d and 41e be entered in the locating slot of detent mechanism portion 43 and 44 from fixed pivot pin 24.
When make take out hook 75 and move to Fig. 8 right-hand member after, when clockwise direction drives gear wheel 61, make sliding pin 74 as shown in Figure 9, only in the arc sections (c) of cam path 72a of arc position that with axle 60 is the center, move, the angle of taking-up lever 72 does not change.During sliding pin 74 slides in arc sections (c), follower peg 71 is slided in the 2nd curve part (b) of cam path 61a, make trace 51 do bigger rotation with this 2nd curve part (b) to anti-clockwise direction, make position and lock plate 41 to (4) direction significantly move with trace 51 this moment, by connecting link 54 and the 2nd trace 56 position and lock plate 45 significantly moved to (1) direction.
In that gear wheel 61 is rotated in a clockwise direction from phase place shown in Figure 5 during the phase place shown in Figure 9, initial exactly, drive to take out lever 72 and drive to clockwise direction and take out hook 75, the pallet T that in tray salver M, chooses to the diagram right
1Take out.After this taking-up is finished, and then gear wheel 61 is rotated to clockwise direction, significantly drive position and lock plate 41 and 45, for example by the position and lock plate 41 among Fig. 3 is moved to (4) direction, make lock slots 41c leave locking plate 12c, in addition, make locking recess 41h leave fixed pivot pin 24, two mobile chassis 11 and 12 go out of lock, just carve at this moment and not long ago made spacer 41d and 41e be positioned at the location that positions lockplate 41 and the 1st mobile chassis 11 relative frameworks 10 in arbitrary locating slot in the detent mechanism portion 43,44.The action of position and lock plate 45 making the taking-up bar after the clockwise direction rotation, is moved to (1) direction by making position and lock plate 45 too, the 1st mobile chassis 11 is positioned, and make the latch-release of the 1st and the 2nd mobile chassis 11,12.
