Abstract
A locking groove extending in the horizontal direction is formed approximately at the center of a front surface of a cartridge. A power switch is turned on/off in response to an operation of a slide switch. When the power switch is turned on by the slide switch, a lock plate rotates in response to the operation of the slide switch. At this time, a projecting portion provided on one side of the lock plate is fit in the locking groove. Consequently, simultaneously with the turning on/off the power, the cartridge is locked so as not to be ejected.
