Claims

[Scope of utility model registration request]

The machine is divided into parts that can be opened and closed, and a photoconductor set, in which the photoconductor is movably housed in a case with a light introduction port, is installed in one split machine, and a signal light corresponding to image information is installed in the other split machine. In the image forming apparatus, the image forming apparatus is provided with an imaging lens that projects and forms an image from the light introduction port onto the photoreceptor, and the photoreceptor set is provided with a closing position that blocks the light introduction port and the light introduction port is connected to the photoreceptor set. A shutter/cleaning member is provided which can be rotated back and forth between an open position and an open position, and which wipes and cleans the imaging lens during the reciprocating rotation, and the shutter/cleaning member is moved in conjunction with the opening/closing operation of the aircraft body. An image forming apparatus comprising an interlocking mechanism for reciprocating rotation.
