Abstract

PURPOSE: To prevent the degradation in the resolution of the time when a moving type original platen is used by moving a convergent optical transmission body array to the optical center between the original placement surface and the photodetecting surface at the time of performing scanning exposure of originals such as books by using the moving type original platen.
CONSTITUTION: At the time of copying thick originals such as books, an upper cover 10 is rotated 180° and a moving type original platen 16 is used. In this case, a convergent optical transmission body 3 is moved to the optical center position between the top surface of the moving type original platen 16 and a photoreceptor 1 to prevent the degradation in resolution. Thereupon, the convergent optical transmission body array 3 is so disposed as to be able to move between the upper stopper 18 and lower stopper 19 mounted to a body side plate 17 and these are so constituted that when positioning is made by the lower stopper 19 the maximum resolution is obtained for the sheet originals and when positioning is made by the upper stopper 18 the maximum resolution may be obtained for the use of the moving type original platen 16, respectively. In this way, the degradation is resolution may be prevented.
