摘要： A multiple-unit type copying apparatus having an apparatus housing divided into a plurality of units including an optical system unit in which an optical system and a driving device are incorporated and which is openably provided so as to be opened about its one end portion relative to the remaining units. The copying apparatus further includes a connector for coupling the driving device with a power source circuit, a coupling detecting device for detecting a coupling state of the connector and a power supply cut-off device for cutting off power supply to the remaining units when it has been found by the coupling detecting device that the connector is in an uncoupled state.

摘要： A fixing device for fixing images of an original document on a copy material is provided for a plain paper copier. The fixing device comprises a pair of rollers for stressing under pressure the copy material carrying toner powder thereon. The toner powder is tightly adhered to the surface of the copy material to correspond to the images of the original document. In a preferred form, the toner powder is a pressure-fixable developing powder which consists of a wax component and a thermoplastic resin. A developing powder supplier is disposed within a developer powder reservoir for supplying developer powder to a magnet brush. A rotatable cylindrical magnet is provided within said developing powder supplier for generating a non-uniform magnetic field to stir the developer powder within the reservoir. A copy sheet stripping device is also provided which moves in synchronization with the approach of a copy sheet towards the fixing device and to move in synchronization with the separation of the copy sheet away from the fixing device.

摘要： A metal paper guide is disposed near the transcription section for leading a copy paper into the transcription section. The metal paper guide is grounded in the normal operational mode at the normal humidity condition. When the copying machine is placed in a high humidity condition, the metal paper guide is isolated from the grounded terminal for preventing the leakage of charges supplied on the copy paper through the metal paper guide.
