により紙葉を綴じ込むよう構成されている。(Prior art) A conventional Z-type file binding tool has a torsion coil spring arranged on a base plate, one end of which is fixed to a rotatable lever, and the other end bent into a Z shape. The bent rod shaft is connected to the clamping body, and by rotating the lever, the rod shaft at the other end is also rotated to move the clamping body up and down, and the lever is twisted against the board against the coil spring. By locking, the elastic force generated in the torsion coil spring is applied to the clamping body, and the paper sheets are bound by the clamping body.

A locking hole 3 is bored, a shaft support plate 4 is erected at the base end of the substrate 1 and near the side wall 2, and a small shaft 5 is provided between the shaft support plate 4 and the side wall 2. The base end of a lever 6 is rotatably fixed to the small shaft 5, and a support shaft 7 is provided inside the lever 6 along the axial direction.
is constructed, and the respective coil parts of a pair of torsion coil springs 8, 8' are wound on both sides of the tip and base ends of the support shaft 7, and the rod shaft parts at both ends of the torsion coil springs 8, 8' are wound. The rod shaft part 8 inside the coil part
a, 8a' are inserted into horizontal holes 9, 9' provided in the support shaft 7 and fixed therein, and the rod shaft parts 8b, 8b' on the outside of the coil part are attached to the lower edges of both ends of the front wall surface 6a of the lever 6. The lever 6 passes through cutout grooves 10, 10' formed in the lever 6, projects forward of the lever 6, and is connected to both end surfaces of the clamping body 11 as it is. still,
In the figure, reference numeral 12 denotes an auxiliary guide pin connected between the lever 6 and the clamping body 11 and driven by the rod shaft portions 8b and 8b' of the torsion coil spring. FIG. 1 is a perspective view of the lever 6 in its upright state. In this state, the clamping body 11 rotates together with the lever 6 and is completely separated from the upper position of the board 1, and there is no obstacle on the board 1. If there is no such case and the paper sheets to be bound are placed on the substrate, there is no restriction. FIGS. 2 to 4 show the state in which the paper sheets to be stapled are omitted. When the lever 6 is pushed down, the lower surface of the clamping body 11 first comes into contact with the upper surface of the board 1. (Actually, the sheets to be stapled are sandwiched between the board 1 and the clamping body 11), and then the lever 6 is pushed down to release the locking protrusion 13 provided on the rear wall near the tip of the lever 6. When engaged with the locking hole 3 of the side wall 2, the rod shaft portions 8b, 8b' are bent, and due to the deformation, the entire elastic force of the torsion coil springs 8, 8' acts to press the clamping body 11 to the substrate 1. It will be necessary to do so.

に抑えられる利点がある。(Effects of the invention) The present invention has the above-mentioned structure and operation, and when the lever is raised, the clamping body also rotates together with the lever, and the space above the board is completely free of obstructions. This greatly simplifies the work of placing paper sheets on the board. Incidentally, there is a device in which a coil part of a torsion coil spring is arranged inside the lever, which was proposed in a previous utility model registration application filed by the present applicant ("File Binding Device" filed on August 5, 1986). , this allows the rod shaft at one end of the torsion coil spring to protrude out of the rear wall of the lever and fit into the engagement groove provided on the upper edge of the side wall to push down the lever, thereby allowing the lower edge of the rear wall of the lever to be pushed down. and an upper edge of the side wall engagement groove to apply a bending moment to the rod shaft portion, and apply an elastic force based on the deformation to the clamping body connected to the rod shaft portion at the other end, An extremely large force is required to bend the rod shaft at one end of a torsion coil spring, and the force applied to the clamping body is also too strong. The rod shaft part is fixed to the lever or support shaft, and there is no need to bend this part, and a large force is not required to obtain the spring force of the torsion coil spring, improving operability and applying pressure to the clamping body. It has the advantage of being able to moderately suppress the force.
