The negative mask 3 blocks the passage of light from a portion of the negative film F other than the portion located above the aperture, and usually the size signal of the negative film F placed in the document placement area is used to control the size of the negative film F. An object corresponding to the size of F is centered on the optical axis. Specifically, a configuration in which a plurality of negative masks with different opening sizes are provided and one selected from among them is positioned in the document placement area, or a negative mask in which the opening size is variable stepwise or steplessly is provided. It is assumed that the configuration is as follows.

The projection lens 4 is located in the document placement area and the negative mask 3
The image of the negative film F that has passed through is projected at a set magnification at the level where the paper P is positioned. Specifically, a plurality of projection lenses with different focal lengths are provided, and one selected from among them is positioned on the optical axis, or a projection lens with a continuously variable focal length is provided. It is considered to be a composition.

Paper mask 5 is vapor P that is actually baked.
It has an opening that restricts the upper area, and the size and/or position of the opening in the moving direction of the paper P is variable.

For example, as shown in FIG. 3, there is a mask substrate 51 in which a mask opening 50 of length h and width d is formed, and guide grooves 52.5 provided at the upper and lower edges of this mask substrate 51, respectively.

The shutter plates 54 and 54 are divided into two parts by a vertical dividing line, and each shutter plate 54 and 54 is slidably fitted in the #52 and 52, and each shutter plate 54 and 54 can be slidably fitted into each other. It is possible to control the position in the direction and thus the width in the lateral direction (in the direction in which the paper P is moved) of the mutually formed openings by the position of the mutually opposite inner edges 55.55 of each shutter plate 54.54. A paper mask whose size and position are variable is used.

The projection state setting mechanism 20 has a function of setting the aperture size of the negative mask 3, the magnification of the projection lens 4, and the aperture width of the paper mask 5 to a specified state based on a signal from the control mechanism 15. .

The control mechanism 15 also includes a paper mask opening designation mechanism 1.

Then, the paper mask 1; old designation mechanism 18 determines the width of the opening of the paper mask 5, that is, the width T (see FIG. 3 (a)) in the direction in which the paper P is moved, and the position. When set, a printing execution area (its width is indicated by t) where printing is actually performed on the paper P is displayed on the screen 30 of the display device, as shown by the chain line in FIG. .

On the other hand, when the negative film (P) is moved in the moving direction, the image of the negative film F on the paper P is moved perpendicularly to the moving direction of the paper P by the inverting optical system. By appropriately moving the negative film F in the moving direction and adjusting the position while viewing the screen, an image including the desired trimming area will be displayed on the screen 30, and in this state, the image containing the desired trimming area will be displayed. If you specify the burning execution area on both sides 30 so that they match, and then execute the burning process in this state, the image of the burning execution area displayed on the screen 30 will actually be printed on the paper P, and in the end,
An image of the designated trimming area will be formed on the paper P.

In the above, it is not necessarily necessary to display the burn-in area mark M on the screen 30 of the display device.

In the above embodiment, the screen 1fi of the display device is
