When the second gear 2a is further rotated clockwise as shown, the slide gear 96 meshed with the small-diameter gear portions 112a, 112a is rotated.
A, 96B, only pins 95 having only the arcuate inner teeth portions 96b, 96b fitted into the arcuate guide holes 96c, 96d, respectively.
First link member 93 stopped while being guided by 97
A, 93B arcuate internal teeth 93b and lower missing teeth 93c
The upper part is further rotated clockwise to move upward against the urging force of the tension springs 98A and 98B. As a result, the arcuate external teeth portion 96a formed on the rear side slide gear 96B meshes with the small diameter gear portion 130b of the two stage gear 130 provided on the rear side horizontal support plate 99B. It rotates in the counterclockwise direction, and furthermore, the reversing gear 127 meshed with the upper part of the large-diameter gear portion 130a of the two-stage gear 130 rotates clockwise in the drawing around the support shaft 125.
Front horizontal support plate 99A and rear horizontal support plate 99B
The double-sided disc reversing assembly 120, which is reversibly supported between the two, also rotates clockwise as shown to start reversing. At this time, since the one-way clutch 126 is fitted in the center of the reversing gear 127 as described above, when the double-sided disc reversing assembly 120 is reversed, the one-way clutch 126 is integrally formed with the support shaft 125. Working reversing gear 12
7 can rotate, and the driving force at the time of inversion by the inversion motor 102 is transmitted to the inversion gear 127.

At this time, the horizontal support plate 99A on the front side is used.
Does not have a two-stage gear and a reversing gear,
The slide gear 96A on the front side only moves upward on the first link member 93A.

Next, as shown in FIG. 13 and FIG.
Small-diameter gear portions 112a, 11 of the step gears 112A, 112B
When the second gear 2a is further rotated clockwise from the state shown in FIG. 18, the arcuate internal teeth 96 of the slide gears 96A, 96B meshed with the small diameter gears 112a, 112a.
The first link members 93A, 93 in which only b, 96b are stopped
B is further rotated clockwise to extend the tension springs 98A, 9A.
8B moves upward against the urging force of the tension spring 9B.
8A and 98B are in an extended state to store an urging force, and the double-sided disk reversing assembly 120 is further rotated clockwise in FIG. Disk reversal assembly 1
20 is inverted. Here, on the upper surface of the positioning piece 123f formed on the outer surface of the rear tray support plate 123, the tip end portion of the pin 93e moving to the right end side in the elongated hole 99a formed in the rear horizontal support plate 99B is shown. Since the abutting from above is performed, the double-sided disk reversing assembly 120 is maintained at a slight angle with respect to the horizontal state as shown in the drawing. In this state, the reversal of the double-sided disc reversing assembly 120 is completed, and the driving of the reversing motor 102 during the reversal is stopped. At this time, the reason that the double-sided disk reversing assembly 120 is slightly inclined at the reversal completion position is that the pin 93e is brought into contact with the positioning piece 123f at the height of the pin 93e.

In the reversing completed state, the reversing tray 4B is changed to the lower position in the double-sided disc reversing assembly 120, and the desired double-sided disc 3 is placed on the reversing tray 4B with the B side 3b facing up. Is placed. On the other hand, the transport tray 4A has been changed to the upper position.

Next, in order to lower the double-sided disk reversing assembly 120 to the lowered position from the reversing completed state in FIG. 19, the reversing motor 102 is reversed with respect to the driving direction at the time of reversing, but the slide gears 96A and 96B are not rotated. Reversing motor 10
The spring is returned to the ascending position by using the biasing force of the tension springs 98A and 98B stored at the time of completion of the reversal, irrespective of the driving force at the time of the reverse rotation of 2. That is, the slide gears 96A and 96B move down on the stopped first link members 93A and 93B by the urging force of the tension springs 98A and 98B, and
A, 96B return to the position where the arcuate internal teeth portions 96b, 96b of the first link members 93A, 93B are integrated with the arcuate internal tooth portions 93b, 93b, and a pair of pantograph portions 90A,
Return to the raised position where 90B has been raised.

Here, when the slide gears 96A and 96B are moved down by the spring force, the two-stage gear 130 meshed with the arcuate external teeth portion 96a of the slide gear 96B on the rear side and the two-stage gear 130
Although the reversing gear 127 meshed with the step gear 130 is both reversely rotated with respect to the rotation direction at the time of reversing, the reversing gear 127 is rotated.
Since only the reversing gear 127 rotates idle and rotates reversely with respect to the support shaft 125 by the action of the one-way clutch 126 fitted in the double-sided disk reversing assembly 120, the double-sided disk reversing assembly 120 remains in the reversed state without reversing. .

Then, the arcuate inner teeth portions 96b, 96b of the slide gears 96A, 96B and the first link members 93A, 93
When returning to the position where the 3B arcuate internal teeth 93b, 93b are integrated, the reversing motor 102 is reversed with respect to the rotation direction at the time of reversing.
0A and 90B return to the initial state shown in FIG. Therefore, when the double-sided disk reversing assembly 120 completes the reversal at the raised position and returns to the lowered position on the upper surface 21e of the carrier base 21, the height is the same as the initial position before the reversal.

Thereafter, the desired double-sided disc 3 placed on the reversing tray 4B is conveyed to the disc drive unit 180 by the double-sided disc reversal / carrier unit 20, and the desired B-side face of the desired double-sided disc 3 is set in the disc drive unit 180. 3b, the recording and / or reproduction to and from the desired double-sided disc 3 is integrated with the reversing tray 4B.
Is returned to the double-sided disk inversion / carrier unit 20, the desired double-sided disk 3 is again inverted in the double-sided disk inversion / carrier unit 20, and the transfer is performed in a state where the A side 3a of the desired double-sided disk 3 is up. After being placed on the tray 4A, it is collected at the original position in the magazine 10, so that the A
The management of the side and the side B can be omitted.

Also, since the drive source (motor) for reversing the double-sided disk reversal assembly 120 is not attached to the double-sided disk reversal assembly 120, the wiring to the drive source (motor) is routed on the double-sided disk reversal assembly 120 side. Is eliminated, and the double-sided disk reversing assembly 120 can be configured to be lightweight, so that the load at the time of reversing the double-sided disk reversing assembly 120 is reduced, and the quality and reliability of the apparatus 1 can be improved.

[0153]

The double-sided disc reversing mechanism according to the present invention and the disc having the double-sided disc reversing mechanism according to the present invention described in detail above.
According to the autochanger device, in particular, a pair of pantograph sections in which the first link member and the second link member are crossed in an X-shape on the front side and the back side on the carrier base are lowered and raised on the carrier base. And a pair of horizontal support plates constituting a part of a pair of pantograph parts, the double-sided disk reversing assembly is reversibly supported by a driving unit provided on the carrier base side. The pair of pantographs are moved up and down, and when the double-sided disk reversing assembly reaches the ascending position integrally with the pair of pantographs, the driving unit reverses the double-sided disk reversing assembly. Since there is no drive source such as a motor, it is wireless, and there is no danger of wire breakage even if the double-sided disc reversing assembly is reversed, and Reversing load during the double-sided disk reversing assembly is reduced because a double-sided disk reversing assembly can be constructed light in weight. In addition, since the drive unit uses both the function of moving the pair of pantograph units up and down and the function of reversing the double-sided disk reversing assembly with one motor, the component cost of the apparatus can be reduced. In addition, the first link member and the second
The pair of pantograph sections having the link members crossed in an X shape can move up and down smoothly without requiring assembly accuracy. Further, the double-sided disk reversing assembly can maintain the same height position on the carrier base at the lowered position before reversing and the lowered position after reversing.

In the double-sided disk reversing assembly, a first tray for transport on which a double-sided disk is mounted and a second tray for reversal formed in the same shape as the first tray are mounted on the lower and upper stages, respectively. A pair of disc chucking members are disposed opposite to each other at the ends of a pair of lever means which are openably and closably attached to the reversing frame and above and below the reversing frame, respectively. Immediately before closing the pair of lever stages, the pair of disk chucking members are inserted into the center hole of the double-sided disk from above and below to hold the double-sided disk with the pair of disk chucking members, and when the reversing frame is not inverted. Disc chucking means for opening the pair of lever means and retracting the pair of disc chucking members from the center hole of the double-sided disc. When the double-sided disk is inverted by inverting the rolling assembly, at least one of the upper and lower disk chucking members enters the center hole of the double-sided disk, and movement of the double-sided disk in the radial direction is regulated. The two-sided disc is moved to the first and
Since it does not dance in the space formed between the second trays, the signal surface of the double-sided disc is not damaged, and the reliability at the time of inversion can be improved.

When the double-sided disk reversing assembly is moved up and down between the lower position and the upper position on the base (or on the carrier base), the disk chucking means:
While the pair of levers is closed in conjunction with the upward movement of the double-sided disk reversing assembly, and the pair of levers is opened in conjunction with the lowering of the double-sided disk reversing assembly, the pair of levers is opened and closed. There is no need to provide a drive source in the double-sided disk reversing assembly.

When the double-sided disk reversing assembly is moved up and down between the lowered position on the base (or on the carrier base) and the raised position, when the double-sided disk reversing assembly reaches the lowered position, the double-sided disk reversing assembly is moved downward. Since the locking means for locking the disk reversing assembly to the base (or the carrier base) is provided, the double-sided disk reversing assembly is positioned at the lowered position on the carrier base and mounts a desired double-sided disk in a locked state. Thus, the pulling-out operation of the first tray or the second tray can be reliably performed.
