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 having a skirt member surrounding a stencil plate.

[0002]

2. Description of the Related Art Heretofore, various stamps for printing a company name, an address, and other various character strings on the surface of a sheet, in which a stamp face portion is made of rubber, 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, a desired pattern can be pierced by irradiating infrared rays or a thermal head, and by penetrating ink from a group of perforations, it can be used for printing various patterns such as character strings, figures, and marks. Heat-sensitive stencil paper has been put to practical use.

The applicant of the present application has disclosed in Japanese Utility Model Laid-Open Publication No. Hei 5-74833 a stencil printing plate mainly comprising the heat-sensitive stencil sheet and an impregnated body impregnated with ink. A stencil printing plate suitable for making a stamp instead of a rubber stamp was proposed.

[0005] This stencil printing plate is obtained by adhering an impregnated body impregnated with ink to a synthetic resin film and a frame surrounding the impregnated body. The stencil sheet is bonded.

When the stencil printing plate is applied to a stamp, the stencil printing plate is bonded to the lower surface of the base of the stamp member having a grip portion via a cushion material, and the heat-sensitive stencil printing paper is irradiated with infrared light or the like. If a pattern such as a desired character string is perforated by the thermal head, a stamp capable of printing the pattern such as the desired character string on a sheet many times is obtained in the same manner as a normal stamp.
Hereinafter, a stamp using this stencil printing plate is referred to as a stamp body.

[0007] The stamp body is provided with a stencil printing plate having various stamp face sizes and stamp face shapes so as to be adapted to various uses of the user. Accordingly, the heat punching apparatus for performing the punching process is also configured to be able to punch the various types of stencil printing plates. Normally, in a heat-punching device that performs a punching operation with a thermal head, the size of the thermal head is matched to the width of the stamp face portion of the stamp body having the largest stamp face size among those that can be punched by the apparatus. A stamp body having a smaller stamp surface width has been dealt with by limiting the number of heating elements driven by the thermal head.

In the stamp body to which the heat-sensitive stencil sheet is applied, the heat-sensitive stencil sheet located on the lower surface of the impregnated body constitutes the stamp face portion. Ink leaks from the stamped surface due to its own weight, and there is no protective member to protect the stamped surface, so the stamped surface is damaged or dust adheres to the stamped surface, resulting in poor printing performance There was a problem that it was easy to do.

For this reason, there has been proposed a stamp body in which a vertically movable skirt member surrounding the outer periphery of the heat-sensitive stencil plate is added to the stamp body. This skirt member lowers when the stamp is not required, acts as a leg for supporting the stamp body, and acts so that the stamp surface does not contact the laying surface,
At the time of stamping, when the grip portion is pressed, the skirt member rises relatively to the stencil printing plate, so that printing can be performed on the surface of the paper by the stamp surface portion.

[0010]

However, in a stamp body provided with the skirt member, when a character string is pierced with a mirror character on the stamp face, particularly when piercing processing is performed with a thermal head, the skirt member is heated. It interferes with the perforation mechanism of the perforation device and becomes an obstacle to prevent the thermal head from contacting the stamp surface. If the holes are forcibly punched in this state, the skirt member may come into contact with the thermal head itself, causing scratches and the like, which may damage the thermal head.

If the thermal head is configured to be smaller than the width of the stamp face of the stamp body to be perforated, it is possible to insert the thermal head inside the surrounding of the skirt member. The operable range is limited by interference with the members. For this reason, a blind spot that cannot be pierced occurs in a portion of the stamp surface near the skirt member, and sufficient piercing cannot be performed.
Also, in this case, the stamp body that can be used is limited, so that it is not practical.

Therefore, when drilling, it is necessary to raise the skirt member above the height of the stamp surface.

In the conventional heat punching apparatus, a projection is provided on a heat sink provided on a punching mechanism including a thermal head, and the projection is brought into contact with a skirt member from below to forcibly push up the skirt member. A device that performs a perforation operation has been devised. However, as described above, there are various types of stamp surfaces of stamps, and skirt members surrounding the stamp surfaces also have various forms. Therefore, the shape of the skirt member that can be accommodated by the convex portion fixedly provided on the heat sink is limited, so that it is not possible to perforate all the stamps.

An object of the present invention is to prevent the ink from leaking or contaminating the stamp face even when left standing in an upright state when not needed, and to be mounted on a heat punching apparatus regardless of the stamp face size. An object of the present invention is to provide a stamp unit that can perform perforation freely without damaging the perforation mechanism.

[0015]

In order to achieve this object, a stamp unit according to the present invention is provided with a grip portion for gripping by hand, and is fixed to the grip portion so that the ink body and the surface of the ink body are fixed. A stencil printing plate including a heat-sensitive stencil sheet constituting a stamped surface portion, and a detachable mounting on a heating punching device, wherein the stamped portion is perforated with a dot pattern, and further, A skirt member which surrounds the outer peripheral side of the stencil printing plate and is supported so as to be able to ascend and descend over a first position in which a lower end portion protrudes below the stamp surface portion and a second position where the stamp surface portion is exposed; At the time of mounting to the heating perforation device or at the start of the perforation operation by the heating perforation device,
A release member which engages with a predetermined member in the heating perforation device and raises the skirt member to a third position where the lower end of the skirt member is higher than the height of the stamp face.

A cam means for lifting the skirt member when the stamp unit is mounted on the heating punching device is provided at a portion where the release member and a predetermined member in the heating punching device are engaged. It may be provided.

The release member may engage with a guide bar as the predetermined member extending in the same direction as the direction in which the stamp unit is mounted.

The release member is fixedly provided on the skirt member, and is provided in the same direction as the direction in which the stamp unit is mounted on the heating and punching device, and has a guide hole through which the guide bar is inserted. May be.

[0019]

In the stamp unit of the present invention having the above-described structure, perforations are formed in a large number of desired patterns in advance on the heat-sensitive stencil sheet forming the stamped surface, and the stamped surface is gripped by the gripping portion. When pressed, the ink of the ink body oozes out from the many perforations, so that a desired pattern can be printed on the surface of the paper.

The skirt member which can be raised and lowered surrounding the outer peripheral portion of the stamp portion descends when the stamp is unnecessary, and serves as a leg for supporting the stamp unit. The stamp surface portion acts so that the stamp surface does not come into contact with the laying surface. The stamp surface portion can be protected. Further, at the time of stamping, when the grip portion is pressed, the skirt member rises relatively to the stamp portion, so that printing can be performed on the surface of the paper by the stamp surface portion.

Further, the release member is engaged with a predetermined member in the heating perforation device when the release member is attached to the heating perforation device or when the perforating operation is started by the heating perforation device. During the drilling operation of
Lifted above the height of the stamp face. Therefore, the skirt member does not hinder the operation of the piercing mechanism in the apparatus or damage the piercing mechanism.
