DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamp unit, and more particularly to a stamp unit in which a stamp face is made of a heat-sensitive stencil sheet instead of rubber.

[0002]

2. Description of the Related Art Conventionally, various stamps for printing a company name, an address, and other various character strings on paper have been used.
This type of stamp is expensive because the stamp is usually created individually according to the order, and the period from order to acquisition is long. On the other hand, conventionally, heat-sensitive stencils that can be used for printing various patterns such as character strings, figures, marks, and the like can be formed into a desired pattern by irradiating infrared rays or a thermal head, and by transmitting ink from the group of holes. Base paper has been put to practical use.

[0003] The applicant of the present application has disclosed in Japanese Utility Model Laid-Open No. 5-74833 a heat-sensitive stencil sheet mainly composed of the heat-sensitive stencil sheet and an ink-impregnated body, wherein the conventional stamp face is made of rubber. A heat-sensitive stencil sheet suitable for making a stamp in place of the constituted stamp was proposed. This heat-sensitive stencil sheet is obtained by bonding a synthetic resin film to an impregnated body impregnated with ink and a frame surrounding the impregnated body, and applying a heat-sensitive stencil sheet to the surface of the impregnated body and the frame body. It is a configuration in which it is bonded. However, a removable film-like separator may be mounted between the impregnated body and the heat-sensitive stencil sheet.

When the heat-sensitive stencil sheet is applied to a stamp, the heat-sensitive stencil sheet is bonded to a lower surface of a base of a stamp member having a grip portion via a cushion material, and the heat-sensitive stencil sheet is irradiated with infrared rays or the like. If a pattern such as a desired character string is pierced by a thermal head, the stamp is formed of a stamp member and a heat-sensitive stencil plate. A stamp can be obtained which can be printed on paper many times.

[0005]

In the stamp to which the heat-sensitive stencil sheet is applied, the heat-sensitive stencil sheet located on the lower surface of the impregnated body constitutes a stamp face. Because a certain frame is provided, it is difficult to position the stamp face at a desired position on the surface of the paper during printing, and if the stamp is placed upright when not in use, the stamp face will have its own weight.
