処理する必要があった。By the way, in the conventional cutter device 13, the photographic printing paper A is fed out by a predetermined length by the rotation of the feed rollers 12a and 12b, and when the photographic printing paper A is stopped, the movable blade 13b is removed. Since the movable blade 13b is reciprocated, the movable blade 13b cuts the photographic paper A as shown in FIG. 3B and rises as shown in FIG. Rub Lee and rise. For this reason, the cut edge a of the photographic paper A may be scratched by contact with the movable blade 13b, and the photographic paper A may be delaminated,
When the photographic print was formed, the quality was poor and it was necessary to print again.

が停止する。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows a cutter device for cutting photographic paper. The cutter device includes a fixed blade 1 and a movable blade 2 that is moved with respect to the fixed blade 1. The movable blade 2 is provided with an operating piece 3, and a moving path of the operating piece 3 is provided with an upper dead center detection switch SW 1 and a lower dead center detection switch SW 2 of the movable blade 2. These switches SW 1 and SW 2 are operating pieces 3
Drive device (not shown) that moves the movable blade 2 up and down when the switch SW 1 for detecting the top dead center is actuated by
Stops.
