Next, the operation of the control circuit 15 will be described with reference to the flowchart of FIG.

FIG. 2 is a subroutine showing a process when a signal for instructing the ejection of the disk cartridge C transmitted from the transmitter 11 of the remote controller is input to the control circuit 15 via the receiver 12. At this time, the control circuit 15 first determines whether or not the disc tray 7 is in the open state based on the input from the tray position detection switch 13 (step 21). When the disc tray 7 is in the closed state instead of the open state and NO is determined, the ejection signal is output to the motor drive circuit 16 to eject the disc cartridge C (step 22). on the other hand,
When YES is determined in step 21, that is, when it is determined that the disc tray 7 is protruding from the main body, the disc cartridge C is not ejected and the process directly returns to the main routine.

As described above, in this embodiment, even when the disc cartridge C ejection command signal is input to the control circuit 15, ejection of the disc cartridge C is prohibited when the disc tray 7 is in the open state. Therefore,
It is possible to avoid the inconvenience that the disk cartridge C is suddenly ejected while the disk is being placed on or taken out from the disk tray 7 and the operation of the disk tray 7 is disturbed as in the conventional case. The control for prohibiting the ejection of the cartridge is performed when the eject operation signal is output from the remote controller.When the eject operation of the cartridge is performed by the operation button on the operation panel of the main body, the disc is ejected. Whether the tray 7 is open or closed, the eject operation of the disc cartridge C is performed as it is. This is to prevent others from being able to eject the cartridge with the remote controller when the disc tray 7 is open. When operating the main unit directly, there is a problem such as when using the remote controller. Because there is no.

In this embodiment, there is shown a disc loading device in which the disc cartridge C is provided as the first disc feeding / discharging member in the upper stage and the disc tray is provided as the second disc feeding / discharging member in the lower stage. However, the present invention is not limited to this, for example, a disc loading device having a disc tray on the upper stage and a disc cartridge on the lower stage,
Alternatively, it is obvious that it includes a disc loading device and the like in which disc trays are provided in upper and lower stages, respectively.

〔effect〕

As described above, according to the present invention, even when the discharge command signal of the lower disk supply / discharge member is input to the control circuit,
When the upper disk supplying / discharging member is in the open state (discharging position), the discharging of the disk supplying / discharging member to be discharged is prohibited. Against the disk supply / discharge member in operation, the upper disk supply / discharge member is suddenly discharged by an erroneous operation of the remote controller by another person while the disk is being placed or removed. Inconvenience such as operation being hindered can be avoided.

However, when operating the operation section on the main body side, the operator can recognize that the lower disk supply / discharge member is in the discharge position.In this case, the lower disk supply / discharge member moves to the discharge position. However, the upper disc supply / discharge member can be moved in the discharge direction. Therefore, both disc supply / discharge members can be moved in the ejection direction by operating the operation portion on the main body side, and both disc supply / discharge members can be operated simultaneously or repeatedly quickly.
