A motor 57 is attached to one corner of the outer frame 52, and is attached to the inside of the outer frame 52 by the motor 57 so as to be movable in the Y direction, as shown in the perspective view of FIG. The belt 60 is rotated. Since the inner frame 53 is fixed to the belt 60 at the mounting portion 61, by controlling the rotation of the motor 58, the position Y ₀ of the negative film 1 is moved through the inner frame 53 in the Y direction orthogonal to the optical axis.

With the above-described structure, the frame position of the negative film 1 is set to the perforation 6 as shown in FIG.
When the position of 6 and the position of the positioning pin 67 do not coincide with each other, the pressing plate 64 does not press the negative film 1, so that the position can be moved without being determined. As shown in FIG. 7B, the position of the perforation 66 is changed. And positioning pin 6
When the positions of 7 coincide, the pin 67 penetrates the perforation 66 and the pressing plate 64 presses the negative film 1, so that the positioning is accurately performed. Instead of the mechanical positioning in the feeding direction of the negative film 1 with respect to the exposure stage 54, for example, a method of photoelectrically detecting the boundary position of the frames to perform positioning can be adopted.

The projection magnification M of the zoom lens 18 is calculated from the arithmetic expression M = C · PA · m ₁ / m ₂ stored in 1, and the magnification of the zoom lens 18 is controlled via the driver 40. Further, when the diagonal position coordinates of the print frame 8 are designated, the size of the opening of the mask 21 is controlled. That is,
Assuming diagonal position coordinates X ₁ , X ₂ , Y ₁ , and Y ₂ of the print frame 8, the projection magnification M of the zoom lens 18 calculated above is calculated.
By using the position x ₁ , x ₂ , y ₁ , y ₂ of the mask heads 71 to 74 of the mask 21 in the CPU 31 as x ₁ = M.
X ₁ , x ₂ = MX ₂ , y ₁ = MY ₁ , y ₂ = MY ₂ are calculated, and the control signals corresponding to these positions are sent to the driver 41, and the rotation amounts of the motors 91 to 94 are separately calculated. Control. When the position of the print frame 8 is not designated, the rotation of the motors 91 to 94 is controlled so that the mask heads 71 to 74 have the print size (PA) around the optical axis.
