Flat clinch type stapler

Abstract

PROBLEM TO BE SOLVED: To provide a flat clinch type stapler capable of bending and binding a staple in a flat state without causing buckling or the like to the staple. ; SOLUTION: The flat clinch type stapler includes a paper table 3 for attaching papers P to be bound, a magazine 5 disposed opposite to the paper table 3 and holding the staple N, a pushing blade 7 for pushing the staple N held in the magazine 5 toward the direction of the paper table 3, an anvil 13 in which either bending abutting faces 9 or forming abutting faces 11 bend penetrated end portions N1 of the staple N which is pushed by the pushing blade 7 and has penetrated the papers P, and an abutting face switching mechanism that engages the staple N with the forming abutting faces 11 after engaging the staple N with the bending abutting surfaces 9 at the time of bending action by the anvil 13.

Description

technical field [0001] The present invention relates to a flat clinch type stapler for binding paper. Background technique [0002] Conventionally, as such a stapler, a stapler equipped with the following components is known (for example, refer to Patent Document 1): a paper table for adding paper to be stapled; a staple magazine, which is opposed to the paper table arranging and holding staples; a pusher for pushing out the staples held by the staple magazine toward the paper stage; and a chopping board for pushing out and penetrating the through ends of the staples of the paper by the pusher Bend at the bottom. [0003] However, in a conventional stapler, an abutment surface for guiding and bending the penetrating end portion of the staple is formed on the tip end of the fixed cutting board. The abutting surface is inclined in a direction that guides the leading end of the staple inward with respect to the paper. Therefore, in the final stage of bending, it is difficult...

Problems solved by technology

Therefore, in the final stage of bending, it is difficult to sufficiently push the root portion of the through end of the staple toward the paper direction, and the binding may be completed in a state where the root portion bulges slightly away from the paper. bad situation

[0004] Such a problem can also be alleviated by setting the inclination of the abutting surface to be relatively gentle in advance, but if this is the case, it will be difficult to guide the top end of the staple to the inside smoothly at the initial stage of bending, and there is a tendency to cause the staple to be bent. Difficulties such as the problem of vertical bending at the through end
