PURPOSE: To print and expose an original picture on the desired position of a photosensitive material by moving a roof reflecting member so that the original picture projected position of the photosensitive material may be changed.

CONSTITUTION: The roof mirror 31 is set at a specified position through a moving means 40 based on the set position data of the 1st frame of the roof mirror 31 held so that a ridge 37 may be tilted at the angle of 45° with respect to a printing optical path outgoing from a printing lens 30 between the printing lens 30 and a color paper 10 by a guiding means 36. Since the reflecting position of a printing optical axis is changed when the roof mirror 31 is moved in a right direction by a specified quantity L1 by the mirror 31 moves in parallel by 2L1 which is double L1. Therefore, the moving process of the moving means 40 is made the half of the actual parallel moving quantity of the printing optical path on the color paper 10, so that the constitution of the moving means 40 is made compact. Thus, a package print or an album print can be prepared with the simple constitution.
