DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film mounter which is used for cutting a long micro film frame such as a 35 mm film and attaching it to an aperture of an aperture card.

[0002]

2. Description of the Related Art In a conventional film mounter of this type, an aperture card is inserted between a lower surface of a holding member and a pair of fixed blades disposed below the holding member, and a movable surface facing between the fixed blades from below. The blade is raised to cut out a predetermined frame, and the cut frame is pressed against an aperture card and adhered to the aperture.

[0003] The film is fed between a pair of upper and lower rollers, and crosses below one fixed blade, enters above the movable blade, and enters under the other fixed blade. This film must be correctly positioned above the movable blade.

[0004]

[Problems of the prior art] However, the roller for feeding the film is
Since the surface is covered with an elastic material such as rubber, it is inevitable that the elastic material will be worn out, deteriorated, or severely deformed by use. In addition, play (play) may occur in the roller bearing.

In such a case, when the film is fed between the upper and lower rollers, the direction of the film may become unstable when leaving the rollers, or the film may bend left and right (in the width direction of the film). Then, the film is not correctly positioned on the movable blade, and is tilted on the movable blade.

Therefore, when a frame is cut out from the film as it is, the frame becomes a parallelogram instead of a correct right quadrangle. On the other hand, since the aperture of the aperture card is formed in a right-angled quadrilateral, when this piece is stuck to the aperture, a displacement occurs between the two. For this reason, there arises a problem that the frame cannot be accurately attached, or the attachment is incomplete and easily peeled, resulting in a failure.

[0007]

Next, the operation will be described. First, the aperture card 10 with the protection paper 16 is inserted into the card insertion slot 18 and the protection paper 16 is peeled off. Next, the aperture card 10 is inserted into the card insertion slot 24 of the cutout portion 28. The tip of the card 10 is positioned by hitting the stopper pin 25 (see FIGS. 4 and 6). At this time, the aperture 12 comes above the movable blade 34.

The microfilm 80 is a film guide 7
6 and its leading edge is inserted between rollers 82 and 84. When the feed switch 96 is pressed once, the film 80 is moved to the film guide 78 and the film holding plate 86.
Is sent to the left by one frame. If the feed switch 96 is pressed appropriately, the film 80 passes through the film path 50 of the fixed blade 48 on the right side, and enters the upper side of the movable blade 34 while both edges are guided by the film guides 58, 58. The front end of the film 80 enters the film passage 50 of the fixed blade 48 on the left.

In this state, the center of the frame is aligned with the center of the aperture 16 using the fine movement knob 88, and the feed switch 96 is pressed to confirm the feed amount per frame feed. By repeating this operation, the film feed adjustment lever 90 is adjusted so that the amount of one feed is correctly set for one frame.

When the mount switch 98 is pressed after the adjustment of the feed amount is completed, the movable blade 34 moves up and down once. During the rise, the blade plates 46, 46 of the movable blade 34 cross the openings of the film passages 50, 50 from bottom to top while closely contacting the end faces of the fixed blades 48, 48. Therefore, both ends of the film 80 can be cut off while leaving the frame on the upper surface of the movable blade 34.
The movable blade 34 further raises and cuts the top and presses it against the adhesive tape 14 of the aperture card 10 to attach the top.
At this time, the rubber plate 64 is compressed to prevent an excessive pressure from being applied to the top and the adhesive tape 14.

When the movable blade 34 descends, the blower 100
The dust cut off by the left fixed blade 48 is sent to the dust receiving box 22 by the wind.

If the film 80 bends when the film 80 is fed between the rollers 82 and 84, FIG.
The driver 78D is inserted into the driver hole 78C and the screw 78B is rotated as shown in FIG. By the rotation of the screw 78B,
The film guide 78 rotates about the vertical axis A integrally with the film holding plate 86, and the feeding direction of the film 80 changes. In this way, the film 80 is adjusted so as to enter the movable blade 34 at a correct position.

The film guide 78 rotates around the vertical axis A.
Since the angle is adjustable, it enables the fine adjustment of the feeding direction of the film 80, the positioning accuracy of the film 80 is significantly improved. Particularly, the pressing force of the nip roller 84 is changed.
The film 80 is located downstream of the rollers 82 and 84
With the film guide 78, the bending of the film 80 in the feeding direction is sufficiently limited, and the intended purpose can be achieved.
