As shown in FIGS. 1 to 4, a pair of film holding frames 2 are arranged in parallel on one side of the upper surface of the leader support 1. Support plate 3 provided at the rear of the film holding frame 2
The end of is supported rotatably by a pin 5 on a support piece 4 protruding from the upper surface of the reader support 1. Therefore, pin 5
The film pressing frame 2 can be undulated centering around. An elastic plate 6 is attached between the support plates 3 and 3, and the tip end of the elastic plate 6 contacts the pin 5 to urge the film pressing frame 2 forward. In addition, the insertion portion of the pin 5 provided on the support plates 3 and 3 has a long hole shape in the front-back direction of the film pressing frame 2.

Further, as shown in FIG. 2, an engaging claw 8 is formed at an end of the forked piece 7 provided in the front part of the film pressing frame 2, and the engaging claw 8 covers the film pressing frame 2. When tilted, it is inserted into the engagement hole 9 provided in the leader support 1 and engages with the lower surface of the leader support 1. The engagement is such that the elastic plate 6 is slightly deformed by pushing the film pressing frame 2 backward, and the engaging claw 8 is disengaged from the engaging hole 9.

A plate-shaped tape pressing member 10 with a rounded tip is arranged between the bifurcated pieces 7, and two rods 11 attached to the back surface of the tape pressing member 10 have insertion holes 12 formed in the film pressing frame 2. It is slidably inserted in. Therefore, the tape pressing member 1 is moved in the front-back direction of the film pressing frame 2.
0 can be moved, and the knob 13 for the moving operation
Is provided on the tape pressing member 10.

When the film pressing frame 2 is tilted and locked on the leader supporting base 1, the tape pressing member 10 has its tip end abutting against the upper surface of the leader supporting base 1, and the contact causes the bending portion 14 provided at the center to be bent. Deflection occurs. Therefore, the tip of the tape pressing member 10 elastically contacts the upper surface of the leader support 1.

The film storage container P is set inside the film holding frame 2 which is held in a lying state. A slender opening 15 is provided in the front part of the film F in the film withdrawing direction, which is drawn out from the film storage container P. The film F is rotatably supported in the up-down direction as a center, and the tip of the film F is cut by the fixed blade 17 attached along the side edge of the opening 15 when the film F is rotated downward.

The upper surface of the fixed blade 17 is lower than the upper surface of the leader support 1, as shown in FIG. Therefore, the opening 1
