Is configured.

The receiving / transferring means 3 includes a transfer position at which the receiving / transferring means 3 approaches the resin-molded optical disk supply means 2 indicated by a two-dot chain line, and a separation position which retreats from the resin-molded optical disk supply means 2 as indicated by a solid line. An advancing / retracting mechanism 9 for advancing and retreating between the positions, a receiving boss 10 removably fitted to the center hole 1A of the resin molded optical disk 1 when moving to the transfer position indicated by a two-dot chain line, and the receiving boss 1
0 is provided so as to be able to protrude and retract on the radially outer surface of the resin-molded optical disk 1 around the center hole 1A around which the receiving boss 10 is fitted. And an optical disk holding mechanism 11 for holding the receiving boss 1 by the urging of a spring (not shown).
Consisting of a plurality of balls protruding from the surface of
In the process in which the receiving boss 10 is fitted into the center hole 1A of the resin molded optical disk 1, the hole surface of the center hole 1A interferes and is immersed until it is flush with the surface of the receiving boss 10 against the bias of the spring. Then, when the interference of the hole surface of the center hole 1A is released, the spring urges to protrude to the surface of the receiving boss 10 to hold the resin molded optical disk 1, and the receiving boss 10 is moved to the center hole of the resin molded optical disk 1. In the process of exiting from the hole 1A, the hole surface of the center hole 1A interferes with the surface of the receiving boss 10 against the bias of the spring and interferes with the bias of the spring, and the interference of the hole surface of the center hole 1A is released.

[0009]

However, in the conventional resin-molded optical disk transfer device, centering is performed by bringing the outer periphery of the resin-molded optical disk into contact with the inner periphery of the peripheral portion of the centering ring. On the other hand, the more the resin molded optical disk moves toward the outer peripheral portion, the larger the "warp" becomes, so that proper centering cannot be expected. Also, since the resin molded optical disk is held by suction while being placed on the ring portion of the metal centering ring, unless the advance / retreat movement amount of the advance / retreat movement mechanism is set very carefully, the resin molded optical disk is received by the resin molded optical disk supply means. There is a drawback that the transfer means interferes to prevent proper operation.

Accordingly, the present invention provides a resin-molded optical disk capable of performing proper centering and absorbing an error even if a slight error occurs in the amount of movement of the movement mechanism. The purpose of the present invention is to provide a transfer device.

A spring that presses and biases to a stroke front end that can be fitted into the center hole of the resin molded optical disc, and an intake / exhaust mechanism that provides the suction pad with an intake function and an exhaust function,
The receiving / transferring means includes an advancing / retreating mechanism for moving the receiving / transferring means between a transfer position for approaching the resin-molded optical disk supply means and a separation position for retreating from the resin-molded optical disk supply means, and a movement to the transfer position. A receiving boss which is sometimes retracted against the bias of the spring, the centering boss is withdrawn from the center hole, and the receiving boss is removably fitted into the center hole, and a radial direction of the receiving boss is provided. An optical disk holding mechanism that is provided on the outer surface so as to be protrudable and retractable, and engages with a surface of the resin molded optical disk supply means side around the center hole where the receiving boss is fitted to hold the resin molded optical disk. It is characterized by.

According to the present invention, the centering boss is removably fitted into the center hole of the resin-molded optical disc to perform centering of the resin-molded optical disc. Can be properly centered irrespective of this "warpage".
In addition, since the resin molded optical disk is sucked and held by the suction pad made of an elastic material, even if a slight error occurs in the amount of movement of the movement mechanism, the error is absorbed by the elasticity of the suction pad. An appropriate operation can be obtained.
