PURPOSE:To control the scanning start of a plate picture by the movement of an original platen and to simplify the constitution of a copying device by moving an original platen at the copying of the plate picture in addition to the copying time of an original. CONSTITUTION:The copying device is provided with a box body 2 of a copying process part 1, a box body 28 of a plate writing part, a movable original platen 10, etc. an original copying mode is set up by a copy command key switch 16 on the box body 2, and at the copying of an original, a photosensitive body 3 is rotated. At the copy of a plate picture, a power switch 30 arranged on the box body 28 side is depressed, the depression is detected by a detecting switch 31 and a motor 21 is actuated by a control circuit 32 and a motor driving circuit 33. Then, a field lens 27 is abutted or made close upon/to the original platen 10 by depressing the switch 16. The original platen 10 is separated from the switch 13 and the plate picture starts to be scanned in response to a signal formed by the switch 31. Thus, the constitution of the copying device can be simplified. |
