Abstract

PURPOSE:To detect and indicate the size of an original surface to be copied, by providing a photosensitive body irradiating means which directly irradiates with light the surface of a photosensitive body in addition to an original irradiating means which is used for obtaining a reflected image by irradiating the original surface with light. CONSTITUTION:A sensible image is formed on a photosensitive body 10 by a well-known electrophotographic system. Moreover, plural LEDs 32 are installed under an array-like condition along the widthwise direction of the photosensitive body 10 between a fluorescent lamp 20 and developer 24 as an original irradiating means. The light emitting quantity of the LEDs 32 can be set optionally by the quantity of the electric current supplied to the diodes 32 and a control section 34 for controlling the quantity of the electric current is connected to the LEDs 32 through a flexible wiring board 33. The size of the surface 18 of an original 16 placed on an original placing surface 28 is indicated by means of original size indicating bodies 36a, 36b, 38a, and 38b installed on an original table 26.
