PURPOSE:To obtain a less-variation copying machine and to deal with fine magnification variation by storing a storage element with various functions to be varied according to magnification and reading a function value corresponding to set magnification. CONSTITUTION:Specific address input data for fine adjustment of projection lens movement, photographic paper feed, and exposure time are set previously while machine variance is considered. When a magnification setting dial is set to specific magnification after an original A is set on a glass plate 2, a set magnification signal s supplied to a magnification setting circuit 11 and an address for magnificaition is inputted to an ROM13. Then, a projection lens movement mode signal is supplied as a mode switching signal in printing operation to a fine adjustment changeover switch 12 and an ROM13. An address for a fine adjustment of projection lens is selected by the switch 12 and supplied to the ROM13. Thus, an address for projection lens movement corresponding to the specific magnification inputted to the ROM is specified. |
