Image forming device

Abstract

Abstract PURPOSE:To easily copy characters or graphics written on a blackboard in addition to normal copying and to reduce the size of a device by rotating a part of an optical system constituting a screen part. CONSTITUTION:When a power supply is turned on, the screen part 61 is slided from an original platen 2 and normal copying operation can be executed. When a switch key on an operation panel 30 is depressed, a pulse motor 1404 is driven, the screen part 61 is slid over the copying machine body 1, and when an optical system unit 631 is rotated up to a position intersected with the screen part 61, and image on the screen part 61 can be copied by the copying machine 1. When a copy key on the panel 30 is depressed, a pulse motor 84 winds up the screen 65 in synchronism with the rotation of a photosensitive drum 10 and the image on the screen 65 is exposed and scanned by an exposing lamp 66. The reflected light is guided from a window part 67 into the inside of the copying machine 1 through a mirror 97, a lens 74 and mirrors 98-100 to form its image on the surface of the drum 10.
