Abstract

There is provided a novel and useful file that can easily and reliably perform binding operations accompanying the increase or decrease of sheets or the like. The clamping surface 11 and the clamping bottom 12 are separated from each other, so that one of them is formed into a bag shape in the binding side opening 11a, and at the same time, an extension 21 that can be inserted into the aforementioned opening 11a is provided on the other binding side, and the extension 21 In the state inserted into the opening 11a, the extension 21 exposed between the clamp surface 11 and the clamp bottom 12 is used as the clamp back 13, wherein the binding legs 3 are arranged on the clamp 12 on the side where the extension 12 is provided, The binding leg fastening portion 4 is inserted into the front end side 31 of the aforementioned binding leg 3 and fixed in a bent state on the cover 11 forming one side of the bag shape.

Description

technical field [0001] The present invention relates to a file that can easily and reliably perform binding work of paper and the like. Background technique [0002] As such folders, the folders shown in FIGS. 4 and 5 can be referred to. This file folder is that the clamping surface 111 and the clamping bottom 112 are separated from each other, and the clamping bottom 112 is in the shape of a bag with an opening 112a on the side of the binding root. At the same time, on the binding root side of the clamping surface 111, a When the extension 121 is inserted into the opening 112a, the extension 121 exposed between the clamp surface 111 and the clamp bottom 112 is used as the clamp back 113 . [0003] Such a configuration is advantageous in that the thickness of the entire document can be appropriately changed according to the binding amount of paper sheets or the like P2 since the width of the clip back 113 changes according to the insertion amount of the extension portion 12...

AI Technical Summary

Problems solved by technology

Therefore, if the interlocking operation cannot be performed well, and the exposed amount of the extension part 121 constituting the clip back 113 becomes loose, once the crease is recovered, the same operation has to be repeated, and there is also a problem with the reliability of the operation.

It is possible to first fit the extension part 121 into the opening 112a to a certain extent, bend the binding leg 103 substantially, and perform the operation of inserting it through the binding piece 102 and the binding leg stopper 104, but even then, it is necessary to Perform fine-tuning operations, and the operation of sending the extension 121 into the opening for adjustment still has the problem of excessive force or instability. The movement of the binding legs 103 is not comfortable and cannot be inserted through the through-holes 122, and the operability needs to be improved.
