JPH0629867U - Book cover - Google Patents

Abstract

(57) [Summary] [Purpose] This is the cover for binding with fastening hardware. [Structure] A bookbinding cover in which the binding-side outer end faces of the front cover 1 and the back cover 2 are attached to the inner side surface of a fastening member 3 having a U-shaped cross section. [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 outer end surfaces of the cover sheet (1) and the back cover sheet (2) on the binding side are attached to the inner side surfaces of the fastening metal fitting (3) having a U-shaped cross section.

[0005]

[Action]

 Since the present invention has the above-mentioned configuration, when binding using this cover, insert the tips of the bundled sheets (4) into the inner surfaces of the front cover (1) and the back cover (2) as shown in FIG. Then, the tip is guided to the inner surface of each cover and easily reaches the inner surface of the tightening fitting. 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 drawing, it is guided to the inner surface of the cover, and when it reaches the inner surface of the squeezing fitting (3), it becomes a perfectly aligned bundle of paper 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 the binding-side outer end surfaces of the front cover (1) and the back cover (2) are attached to the inner surface of a fastening metal fitting (3) having a U-shaped cross section to form a bookbinding 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.
