As the engaging portion 110 moves in the axial direction along the guide shaft 112, the tray engaging claw 111
Perform a linear motion along.

The tray engaging claw 111 is provided in the engaging recess 91 of the tray 90 so as not to hinder the vertical movement of the tray driving mechanism 100 when, for example, performing a disk change.
Is located at a substantially intermediate position between the contact sides 92 and 93.

Subsequently, the tray driving mechanism 1 having the above-described configuration is used.
The operation of 00 will be described with reference to FIG.

First, when selecting a tray housed in the magazine, as shown in FIG.
Shifts downward with respect to the horizontal line H, and the shaft 113 is slightly shifted inward from the position shown in FIG. As a result, as described above, the tray engaging claw 111 does not come into contact with the engaging concave portion 91 of the tray 90, so that the tray drive mechanism 100 moves smoothly in the vertical direction.

Next, when the selected tray is pulled out, when the small gear 103 rotates in the same direction due to the clockwise rotation of the mode ring 101, the gear portion 105 meshing with the small gear 103 rotates in the counterclockwise direction. As a result, the gear arm 104 rotates counterclockwise, so that the shaft 104b shifts to the horizontal line H as shown in FIG.

At this time, the intermediate gear 107 is
6 by revolving around the periphery of the rotating gear 1
By rotating 08 in a clockwise direction, the tray drive arm 109 is rotated in a clockwise direction. At this time, since the gear arm 104 and the tray drive arm 109 are in the extended state, the tray engaging claw 111 comes into contact with the contact side 92 of the engaging concave portion 91 of the tray 90.

Further, when the mode ring 101 is rotated clockwise by the driving force of the driving gear 102 from this state, the rotation of each gear causes the gear arm 104 to rotate.
Pivots counterclockwise, so that the shaft 104b gradually moves from the line between the shafts 105a and 113 as shown in FIG. 5B.

At this time, the intermediate gear 107 is
6 by revolving around the periphery of the rotating gear 1
By rotating 08 in a clockwise direction, the tray drive arm 109 is rotated in a clockwise direction.

At this time, since the number of teeth of the fixed gear 106 is twice that of the rotating gear 108, the gear arm 104
When rotated, the tray drive arm 109 is doubled in the opposite direction.
rotate θ. Moreover, since the gear arm 104 and the tray drive arm 109 have the same length e, the engaging portion 110 attached to the tip of the tray drive arm 109 moves linearly along the guide shaft 112.

Thus, the tray accommodated in the magazine is gradually pulled out of the magazine by the tray engaging claws 111.

In this way, when the gear arm 104 rotates counterclockwise and the shaft 104b reaches the center line S, the shaft 113 of the tray drive arm 109 coincides with the shaft 105a of the gear 105. Further, from this state, the gear arm 104 moves the shaft 113 of the tray drive arm 109 to the left on the horizontal line H as shown in FIG. Then, when the gear arm 104 and the tray drive arm 109 reach a substantially extended state, the drawing out of the tray from inside the magazine is completed.

On the other hand, when returning the tray to the magazine, when the mode ring 101 rotates counterclockwise, the small gear 103 rotates in the same direction. Small gear 1
03 rotates counterclockwise, and the gear 105 meshing therewith rotates clockwise, so that the gear arm 104 rotates clockwise in the same manner as described above.
4b changes from the state shown in FIG. 3C to the state shown in FIG.

Thus, the engaging portion 110 attached to the tip of the tray drive arm 109 is
When the linear movement is performed in the right direction in the figure along 12, the tray is gradually pushed back into the magazine. In this manner, when the gear arm 104 rotates clockwise and the shaft 104b reaches the horizontal line H, the operation of pushing the tray back into the magazine is completed.

However, in this state, the tray engaging claw 111
Is in contact with the contact side 92 of the engaging concave portion 91 of the tray 90, and the tray engaging claw 111 is
However, when the mode ring 101 further rotates in the counterclockwise direction from the state shown in FIG. 11A in which the gear arm 104 and the tray drive arm 109 are extended, it hinders the movement of the gear ring 104 in the vertical direction. Since the gear arm 104 rotates clockwise in the same manner as described above, the shaft 104b moves downward with respect to the horizontal line H, and the shaft 113 moves slightly in the direction of the arrow. As a result, as shown in FIG. 3, the tray engaging claw 111 is separated from the contact side 92 of the engagement concave portion 91 of the tray 90 by a predetermined distance, and is located at a substantially intermediate position between the contact sides 92 and 93. Therefore, the tray engaging claw 111 and the engaging concave portion 91 of the tray 90 are disengaged, so that the tray engaging claw 111 is prevented from being hindered when the tray driving mechanism 100 moves in the vertical direction.

As described above, in this embodiment, the fixed gear 10
6, the number of teeth is twice as large as that of the rotary gear 108, and the lengths of the gear arm 104 and the tray drive arm 109 are made equal. As described above, when the gear arm 104 is rotated by the angle θ, The tray drive arm 109 as the second arm can be rotated by 2θ in the reverse direction.

Thus, the tray can be pulled out from the magazine by changing the gear arm 104 and the tray drive arm 109 from the extended state to the bent state, and further to the extended state.

When a disc change is performed, the fixed gear 106 is moved from the state shown in FIG.
And by slightly rotating the tray drive arm 109 in the same direction as the direction in which the tray
Can be returned slightly, so that the tray pull-out claw 111
Can be located at a position where it cannot be caught in the engagement recess 91 of the tray 90.

Further, in this case, the tray is temporarily returned to the magazine from the state shown in FIG. 5C, and the tray drive mechanism 100 for pulling out the next selected tray is smoothly moved up and down. 5 (c) until the tray pull-out claw 111 is positioned at a position where the tray pull-out claw 111 does not catch in the engaging concave portion 91 of the tray 90 as shown in FIG.
A series of operations (b) → (a) → (d) is performed by the gear unit 105.
Can be performed by rotating in the same direction,
The control of these series of operations is extremely simple.
