Abstract

(57) [Summary] [Purpose] This is the cover for binding with fastening hardware. [Structure] A bookbinding cover in which a fastening member 3 having a U-shaped cross section is attached to an outer end of a spine 2 of a cover 1. [Effect] The bundled paper sheets can be easily inserted, and the bookbinding work can be efficiently performed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bookbinding cover sheet to which a clamp is attached.

[0002]

[Prior art]

 There has been a conventional method in which a fastening tool having a U-shaped cross section is attached to the inner surface of the cover sheet on the side of binding, and the end portions of the bundled paper sheets are inserted into the cover sheet, and the binding is performed with a dedicated machine tool for binding. For example, JP-A-3-34895. In the above case, however, both sides of the end of the bundled sheets spread outward, and it is difficult to insert the sheet because it collides with both edges of the metal fitting.

[0003]

[Problems to be solved by the device]

 The purpose of the present invention is to provide a cover that can be easily inserted by guiding and guiding the ends of the bundled sheets into the tightening metal fitting on the inner surface of the cover.

[0004]

[Means for Solving the Problems]

 The fastening fitting (3) having a U-shaped cross section is attached to the outer end of the spine (2) of the cover (1).

[0005]

[Action]

 Since the present invention has the above-mentioned structure, when binding using this cover, the front end of the bundled sheets (4) is inserted into the inner surface of the cover (1) as shown in FIG. It is guided to the inside and easily reaches the back. In the case of the present invention, even if there is a non-uniform portion at the tip of the bundle as shown in the figure, it is guided to the inner surface of the cover, and when it reaches the spine (2), it becomes a perfectly aligned bundle of sheets.

Next, when the fastening metal fitting (3) is fastened with a fastening tool (not shown), bookbinding is completed as shown in FIG. Since the tightening device used (not shown) is used on the outside of the cover, it does not require a complicated structure and may be simple.

[0007]

【Example】

 An example will be described with reference to the drawings, in which a fastening cover (3) having a U-shaped cross section is attached to an outer end of a spine (2) of a cover (1) to form a book cover.

[0008]

[Effect of device]

 It is very easy to insert a bundle of paper sheets into the clamp, and thus the bookbinding operation can be performed efficiently.
