As shown in detail in FIG. 7, the mask pressing member 90 has inclined surfaces 95 and 96 at its leading end side facing the film crimping plate 61 and at the opposite side. The inclined surfaces 95 and 96 move from the side of the mask pressing member 90 to the side of the upper mask
It is formed so that the thickness of 0 is gradually reduced. Slope 95
The angle is set according to the pressed portion 83b of the protruding piece 83. When the mask pressing member 90 is at the pressing position, the inclined surface 95 comes into contact with the pressed portion 83b of the protruding piece 83, and the upper mask Press 62.

The urging spring 91 is mounted between the mask pressing member 90 and the film pressure plate 61 and urges the mask pressing member 90 toward the pressing position. In addition, this urging spring 91 is not limited to a coil spring as illustrated,
A leaf spring may be used. Alternatively, an elastic member such as rubber may be used instead of the spring.

Next, the operation of the present embodiment will be described. In the following, an example will be described in which the upper mask 62 for the 135-type photographic film 15 is attached and detached. When the upper mask 62 is not mounted, as shown in FIG. 7A, the mask pressing member 90 is at the pressing position by the urging spring 91. When mounting the upper mask 62, first, the notch 82a is brought into contact with the positioning pin 88 as shown in FIG. At this time, the position of the notch 82a can be easily adjusted because the front end side is wide. By contacting the notch 82a with the positioning portion 93 as described above, the film is positioned in the film width direction, and the falling-off preventing portion 94 prevents the projecting piece 82 from falling off. At this time, the mask pressing member 90 is located at a position adjacent to the positioning pin 89, and the thickness of the mask pressing member 90 is dimensionally larger than the height of the positioning pin 89, so that the notch 83a engages with the positioning pin 89. I can't let that happen.

Next, by rotating the upper mask 62 about the positioning pin 88, the positioning pin 8 is rotated.
The position of the notch 83a is adjusted to the position of No. 9. Then, the protruding piece 83 is pushed along the inclined surface 96 so that the positioning pin 89 is inserted into the notch 83a. Then, FIG.
As shown in (B), the mask pressing member 90 retreats to the non-pressing position, and the protruding piece 83 moves toward the film pressing plate 64. Since the inclined surface 96 is steeply inclined toward the film crimping plate 61, it can be easily moved to the non-pressing position by pressing the protruding piece 83. The mask pressing member 90 is retracted to the non-pressing position, and the notch 83 a is engaged with the positioning pin 89 by moving the protruding piece 83 toward the film pressing plate 64. This engagement prevents rotation about the positioning pin 88 and also positions the upper mask 62 in the film transport direction. Then, when the protruding piece 83 is further pushed into the film crimping plate 64 side, as shown in FIG. Touch At the same time, the urging of the urging spring 91 causes the mask pressing member 90 to return from the non-pressing position to the pressing position, and the inclined surface 95 comes into contact with the pressed portion 83b. The pressed portion 83b is pressed by the inclined surface 95 by the urging of the urging spring 91, so that the protruding piece 83 comes into close contact with the film crimp plate 64.

As described above, the upper mask 62 has the protruding piece 82 provided on one side portion of the upper mask 62.
And the protruding piece 83 provided on the other side portion is pressed by the mask pressing member 90, so that the film pressing plate 64 can be firmly held on the film pressing plate 64. Further, since the film width direction is determined by the positioning pins 88 and the film transport direction is determined by the positioning pins 89, the upper mask 62 can be mounted at an accurate position.

The upper mask 62 is made of resin and is inferior in durability, and needs to be frequently replaced in order to cope with a change in frame size. Therefore, when removing the upper mask 62, the mask pressing member is first moved to the non-pressing position, the fitting between the positioning pin 89 and the notch 83a is released, and the upper mask 62 is removed. Is moved in the film width direction to release the retaining portion 94, the upper mask 62 is removed from the film pressure bonding plate 64. In this manner, the upper mask 62 can be easily attached and detached, so that it can cope with frequent replacement.

In the above embodiment, the upper mask made of resin is used, but the present invention is not limited to this.
The present invention can also be applied to a metal upper mask such as stainless steel. In the above embodiment, the positioning notch is formed on the upper mask side, and the positioning pin is formed on the film crimping plate side. However, the present invention is not limited to this. For example, a projection or the like is formed on the upper mask side, and the film is formed. An opening, a notch, a concave portion, or the like may be formed on the crimping plate side.
