Abstract

The present invention relates to a folder for file, letter head pliers, etc., which can prevent accidental movement of a clamp in a clamping state in a releasing direction. A lining plate (120) is adhibited with a plurality of reinforcing sheets on one edge therefore the lining plate is hard to bend compared with other parts. Furthermore one edge of each reinforcing sheet, which is opposite with other reinforcing sheet, and one edge of another reinforcing sheet, which is opposite with the former edge, are used as guiding parts. The clamp (200) is used for clamping the lining plate (120) and has an approximately U-shaped section. Furthermore the lining plate (120) is sandwiched in the approximate U-shaped section. At positions which are opposite with the guiding part, the projections with widths which are approximately same with that of the guiding part are set in a direction from one side of the U-shaped section to the other side. Each projection is respectively inserted in a corresponding guiding part.

Description

technical field

[0001] The invention relates to a file folder, a letterhead pliers and the like. Background technique

[0002] At present, there are file folders, letterhead pliers, etc., which are bound without punching holes on documents and pocket notebooks, and the applicant of the present invention has also applied for many inventions and utility models (for example, refer to Japanese Patent Documents 1-2). Japanese patent document 4), and the commodity that has used these inventions, utility model becomes long-term bestseller.

[0003] On the other hand, at present, a file folder as described below has also been proposed: the two ends of one side edge of the back cover are folded back to form a side limit stopper to prevent the slider from detaching in the longitudinal direction, and the side limit stopper of the back cover is removed. The part other than the part bends obliquely upwards to the inside to form a lateral limiting stopper, and the inner convex part of th...
