Abstract
Abstract A motor-drive camera using a cartridge film of the camera having a coupled member which is actuated to open the rear cover of the camera and has a first end portion that abuts against the inner surface of rear cover and a second end portion abutting against a cartridge body. The abutment position against the rear cover of the first end portion is changed depending on whether or not the cartridge film is loaded in the camera to switch the electrical current supply to the motor-drive. The coupled member is arranged so that electrical current is supplied to the motor-drive camera by closing the rear cover only after said cartridge film is loaded. The coupled member also operates to pop up a film cartridge when the rear cover is opened.
