PURPOSE:To prevent a graphic deformation, etc., caused by addition of a magnification error at the time of generation copy by providing a means for switching a control of a lens driving means to a usual control mode and a fine adjustment control mode. CONSTITUTION:The titled controller is provided with a means 91 for switching a control of a lens driving means 97 to a usual control mode and a fine adjustment control mode in order to correct a lateral magnification, so that a lens can be moved by a smaller step than that of the time of the usual control mode, at the time of the fine adjustment control mode. In such a way, a fine adjustment of a longitudinal/lateral magnification error can be executed by a simple operation and an inexpensive mechanism, and a graphic deformation, etc., caused by addition of the magnification error at the time of generation copy can be prevented. |
