Abstract

PURPOSE:To diverse copying modes, by arbitrarily adjusting the start and end time points of an image of an image read-in means. CONSTITUTION:An original read-in module 11 consists of a housing, original illumination lamp, and solid-state photo detector etc. A fixed sensor S2 is a sensor which generates an original read-in start signal, and a signal is produced when the movement of the module 11 is started and a detection plate 36 enters a sensor S2. On the other hand, fixed sensors S3 and S4 are sensors producing an original read-in end signal and produce a signal when the detection plate 36 enters the sensors S3 and S4. Movable sensors S5, and S6 have similar function as the fixed sensors S2 and S3 and the original read-in start and end time point are freely changed by slide operation of the sensors S5 and S6.
