Copying available range display device of original platen of copying machine

Abstract

Abstract PURPOSE:To display exactly a copying available range, to match easily the position of an original, and to prevent a miscopy by deriving a reflecting mirror driving signal from a data of a storage device and an inputted frame size, driving a reflecting mirror driving system, and providing an original platen on which oscillated laser light is projected and a frame is copied. CONSTITUTION:A form size is inputted to a CPU2 through a RAM1, and subsequently, the CPU2 determines in advance an amplitude of deflecting mirrors 3, 4 for displaying a frame in size by referring to a ROM5. A data is sent to an I/O6, also the driving system of the deflecting mirror is driven, and drivers 7, 8 drive step-motors 9, 10. Subsequently, the CPU2 supplies an on-signal to a laser driver 11 from the I/O6, makes it generate laser light, and the light A emitted from a laser tube 12 is reflected by the X direction deflecting mirror 3 and goes to light B which is oscillated in the X direction. Also, it is reflected in the upper direction by the Y direction deflecting mirror 4 and goes to light C which is oscillated in the Y direction, too, and when the light C is irradiated to a sheet original on an original platen 13, a frame D is displayed.
