2, a loading drive system configured to pull out the sub-tray from the standby position to the loading position and interlock the optical disc set on the sub-tray with the clamp device in synchronization with the completion of pulling out the sub-tray to the loading position. The loading is composed of the gears 38, 39a to 39i, the fan gear 42, the loading hook 49, the clamp driving rack 76, the clamp support base 79, and the like so that an appropriate one sub-tray can be pulled out from the main tray at the standby position to the loading position. The large-diameter gear 63, the lifting drive lever 65, the lifting right guide plate 66R, the lifting drive system that drives the driving system up and down in the stacking direction of the sub-tray,
The first left / right guide plate 66L, etc., and the first drive switching means for switching the rotation of the motor 19 between the pull-in drive system and the loading drive system are configured by the main gear 17, etc.
The second drive switching means, which is interposed between the output of the motor 19 and the input of the first drive switching means and switches between the first drive switching means and the elevation drive system to transmit rotation, is provided with an intermittent gear 56,
Since the idler gear 30 and the electromagnetic solenoid 61 are used, even if only a single motor 19 is used, the main tray can be pulled in, the loading and the loading device can be moved up and down by switching the first and second drive switching means. .

When the emergency ejection lever 85 is manually operated in the loading completion state, the loading drive system is reversed to return the sub-tray and the optical disk at the loading position to the standby position, and when the gear is further manually operated,
Even if the motor 19 is stopped and the main tray at the standby position moves to the outside of the apparatus main body due to the reverse rotation of the pull-in drive system, all the disks can be ejected to the outside of the apparatus.

In the above embodiment, the emergency ejection lever 85
