Abstract

PURPOSE:To prevent careless contact of finger to a rotating recording medium, by the constitution that the cover is surely locked in a closing state, even if a main power switch turns off when the recording medium is turned. CONSTITUTION:A main power supply switch 10 and a subpower supply switch 11 are inserted between a power supply input terminal 6b of a power supply transformer 7 and itself in parallel. To a power supply output terminal 9a out of output terminals of a rectifying circuit 8, the 1st operation circuit 16 to operate the subpower supply switch 11 consisting a transistor 14 and a relay coil 15 connected to the collector and the 2nd operating circuit 20 to operate a cover lock mechanism 19 consisting of a transistor 17 and a plunger coil 18 connected to the collector are conncted. A plunger 21 controlled with the plunger coil 18 constitutes a part of the cover locking mechanism 19 to lock a cover 3 in a closing state.
