Filed: 1990-07-11
Abstract: PURPOSE:To reduce production cost by constituting a switch so that it may interlock with the loading/unloading of a process cartridge and detecting whether or not the process cartridge is loaded. CONSTITUTION:When the process cartridge 15 is loaded in a device main body 17, a cartridge loading/unloading switch 14 is pressed and turned on by the cartridge 15. Then, a sequence control circuit 11 monitors the voltage of +24V after passing through the switch 14 and judges that the cartridge 15 is loaded, when +24V is supplied, then performs recording processing. When it is not supplied, the circuit 11 judges that the cartridge 15 is not loaded. In a state where the cartridge 15 exists, a user is inhibited from touching the live part or the movable part of an electrostatic charger 10, etc., and jamming processing is performed after removing the cartridge 15. Therefore, a current is shut off through the switch 14 and an accident such as electric shock does not occur.
