ABSTRACT:
An image forming apparatus is provided with a pair of pointers for indicating a range for image formation on an original table. The pointers, which are driven by a pulse motor, can move in a direction perpendicular to the moving direction of an optical system for optically scanning the original. A stopper is attached to at least one end portion of a minimum range for image formation indicated by the pointers. The stopper serves to stop the pointer at position indicating the minimum range. In setting the initial positions of the pointers, pulse output means supplies the pulse motor with a necessary number of pulses for the movement of the indicating means from the minimum-range position to the maximum-range position, thereby causing the pointers to move to a position abutting the stopper.
