Abstract

PURPOSE:To prevent a door from being opened during a specified operating period, by inhibiting the opening of the door while carrying a disc moving means through the provision of the door to a case. CONSTITUTION:At a control section, when a power supply is applied, a reset signal is activated independently of the operation of a door switch 1 and a carrier position and a T type FF111 is set to Q=L and Q'=H, then a drive is reversed until a close limit switch 31b goes to L level (closing state) to close a door 5. On the other hand, the operating signal of the door switch 1 is effective only when a switch 89a detecting a home position of a slider A is at L level (home position), the T type FF111 is inverted and the drive forwards until an open limit switch 31a is at L level (open state) to open the door 1 and reverses until the closing limit switch 31b goes to L level (closing state) to close the door 1.
