Abstract: A counter reset arrangement employed in an image forming apparatus such as a photocopier which is provided with a cartridge removably mounted in a main body of the apparatus and internally accommodating at least a photoreceptor and a cleaning unit integrally, and a resettable counter securely mounted in the main body of the apparatus to detect a remaining service life of the cartridge. The counter reset arrangement includes a reset member movably disposed in the cartridge and having a first protruding portion pressed against at a first position when mounting the cartridge, by a cabinet provided in the apparatus and a second protruding portion formed to press against a reset pin disposed on the counter to reset it.
Abstract: In an electromotive control device having an end disconnect switch, two circular conductive paths are arranged on an insulating support, at least one of said paths being less than an entire circle. Wiper contacts which connect the conductive paths are electrically connected to each other and are connected to a wheel which is driven by a motor, the wheel being mounted coaxially to the conductive paths. The limit disconnect switch and thus a setting element can be manufactured at low cost by the invention.
