Claims

[Scope of utility model registration request]

A movable plate 8 that is rotatable in a direction to cover or open the upper end of the binding punch 4 is attached to the fixed plate 1 on which the required number of binding punches 4 are set up, and the movable plate 8 is attached to the fixed plate 1. The rotating direction is vertical to the sliding direction, and the space between the movable plate 8 and the fixed plate 1 is biased so as to rotate the movable plate 8 in the direction of opening the upper end of the binding punch 4 in the rotating direction. In addition, a spring 16 is attached to urge the movable plate 8 to move to one side in the sliding direction, and a lever 20 having an operating piece 18 is rotatably fixed at a fulcrum 21. At the same time, the core shaft 15 is attached to the bearing part 23 of the link 19 which is rotatably joined to the lever 20 by the connecting part 22.
is inserted into the movable plate 18 so as to be in contact with the hinge bearing cylinder part 11, and when the operating piece part 18 is pushed down to an appropriate position, the link 19 rotates.
The movable plate 8 is provided so as to slide in the direction opposite to the biasing direction of the spring 16 by pushing the side end of the hinge bearing cylindrical part 11, and on the other hand, a stopper piece 12 is provided approximately on the same line as the hinge bearing part 11 of the movable plate 8. established,
Hinge bearing cylinder parts 5 are provided in the side plate part 3 of the fixed plate 1 at a plurality of places and alternately combined with the hinge bearing cylinder parts 11, and the core shafts 15 are inserted into each other and fixed rotatably to form a hinge bearing. A side edge 6a provided on the side plate 3 adjacent to the cylindrical portion 5 is configured to overlap with the stopper piece 12, and when the operating piece 18 is pushed down to the lowest point, the overlapping portion is released and movable. The plate 8 rotates to open the upper part of the binding punch 4, and the side edge 12a of the stopper piece 12 fits into the notch 6 formed in the side plate part 3, so that the side edge 12a is connected to the side edge 6a.
A binder metal fitting for a computer file, characterized in that it is configured to be locked to an end portion 6b of the computer file.
