Works as follows.

First, as shown in FIG. 1, a negative film F was set on a negative mask 5, and a normal print was read on the paper P by the light from the lamp 2 using the normal print lens 6 by the reading means 8. The image is sequentially printed for the number of frames. Thereafter, the negative film F is returned to the printing state of the first frame by the negative film transport means 20, and the lens is automatically switched from the normal print lens 6 to the lens unit 7 for index printing.
Since the number of frames of the negative film is input in advance to the control unit (not shown) of the photoprinting apparatus 1, the exposure position of each frame on the paper P is selected based on the number of frames. . Then, exposure printing is sequentially performed while moving the lens 10 to each of the exposure positions.
Further, the projection magnification of the lens 10 can be changed according to the set print size of each frame. In this way, printing of one negative film F is performed at a predetermined position for each frame, and an index print is completed.

The printing of the index print may be performed in order from the first frame of the negative film F, or after the printing of the normal print is completed, the negative film F may be returned and printed in order from the last frame. It may be.

In this embodiment, the lens 10 is provided with a shielding shutter, but a shutter for normal printing may be used as the shutter of the lens 10 instead of this shutter. Further, as shown in FIG. 4, the paper mask 9 may have a shutter function. In FIG. 4, the paper mask 9 is shown.
