Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamp device,
In particular, the present invention relates to a stamp device including a stamp body having a stamp surface portion made of a heat-sensitive stencil sheet and a heating punching device for forming a punch on the stamp surface portion of the stamp body.

[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 paper, the stamp surface of which is made of rubber, have been used. Stamps of this type are expensive and take a long time from order to acquisition because they are usually made individually according to orders.

On the other hand, conventionally, it is possible to perforate a desired pattern by irradiating infrared rays or a thermal head, and by transmitting ink from the perforation group, it is possible to use it for printing various patterns such as character strings, figures and marks. A heat-sensitive stencil sheet has been put into practical use.

The applicant of the present application has disclosed in Japanese Utility Model Laid-Open No. 5-74833 a stencil printing plate mainly composed of the heat-sensitive stencil sheet and an impregnated body impregnated with ink. We proposed a stencil printing plate suitable for making a stamp that replaces a rubber stamp.

In this stencil printing plate, an impregnated body impregnated with ink and a frame surrounding the impregnated body are adhered to a synthetic resin film, and the impregnated body and the surface of the frame are heat-sensitive. The stencil sheet is bonded.

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

The stamp body is provided with a master plate for stencil printing having various stamp surface sizes and stamp surface shapes so as to meet various uses of users. Correspondingly, the heat punching device for punching is also configured to punch various types of stencil printing master plates. Usually, in a heating punching device that performs punching operation with a thermal head, the size of the thermal head is matched with 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 device. The stamp body having a smaller stamp surface width than that has been dealt with by limiting the number of heat generating 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, but when the stamp member is put upright when not in use, the stamp face portion is Ink leaks from the stamp surface due to its own weight, and because there is no protective member to protect the stamp surface, the stamp surface is damaged or dust adheres to the stamp surface to reduce printing performance. There was a problem that it was easy to do.

Therefore, it has been proposed that the stamp body is provided with a vertically movable skirt member surrounding the outer peripheral side of the heat-sensitive stencil sheet. When the stamp is not needed, this skirt member descends and becomes a leg that supports the stamp body, and acts so that the stamp face portion does not contact the abutment face,
At the time of imprinting, when the grip portion is pressed, the skirt member rises relative to the stencil printing master plate, and printing can be performed on the surface of the paper by the stamp surface portion.

[0010]

However, as described above, the stamp body has a stencil printing plate having various stamp face sizes and stamp face shapes so as to meet various uses of the user. The corresponding heat punching device for punching is also provided so as to punch various types of master plates for stencil printing. However, there is a problem that it is difficult to determine to what position the heating punching device should be attached. Further, if the punching process is not properly performed, the punching process may not be surely performed, and the punching mechanism such as the thermal head may be damaged.

In order to solve this problem, a stopper member or the like is provided on the side of the heat punching device so as to position the stamp body, or a tactile member is provided, and the stamp body is properly attached to the user. There is one configured to give a feeling of wearing (tactile feeling) that conveys that as a feeling. However, in this case, there is a problem that the number of parts is increased by attaching parts such as a stopper member and a tactile member, which leads to an increase in cost.

The present invention has been made to solve the above-mentioned problems, and it is possible to add new parts without adding new parts.
An object of the present invention is to provide a stamping device that can accurately and surely attach a stamp body having a plurality of stamp face sizes to a heat punching device with a tactile feeling.

[0013]

In order to achieve this object, a stamp device of the present invention is provided with a stencil printing plate which is fixed to a grip portion for gripping by hand and which contains an ink body and a heat-sensitive stencil sheet. In the stamp device, wherein the stamp body is detachably attached to the heating and punching device so that the stamp surface portion of the stencil printing plate of the stamp body is punched in a dot pattern, wherein the heating and punching device is the stamp body. A stamp member surrounding the outer peripheral side of the stencil printing plate, the lower end of the stamp member protruding downward from the stamp face portion, and the stamp face portion exposed. A skirt member that can be lifted up and down over two positions, an elastic member that always elastically biases the skirt member to the first position, and the stamp body are attached to the heating punching device. And a release member for engaging the mounting member and lifting the skirt member to a third position where the lower end of the skirt member is higher than or equal to the height of the stamp surface, and between the mounting member and the release member, Positioning means for determining the mounting position of the stamp body is provided.

Further, the positioning means has a concave portion provided in one of the engaging portions of the mounting member and the release member, and a convex portion provided in the other engaging portion and fitted in the concave portion. It is desirable to configure by.

Further, it is desirable that the fitting between the concave portion and the convex portion is held by the biasing force of the elastic member.

Further, the mounting member is constituted by a guide bar extending in the same direction as the mounting direction of the stamp body, and the guide bar is engaged with a guide hole provided in the release member. It may be configured.

A stamp body having a plurality of sizes that can be attached to and detached from the mounting member is provided. It is desirable that each stamp body has a unique size and shape.

[0018]

In the stamping device of the present invention having the above-described structure, the heating punching device is provided with the mounting member for mounting the stamp body and the mounting member, and the skirt member is lifted to the third position. Since the positioning means provided between the stamp body and the release member determines the mounting position of the stamp body, the stamp body can be mounted in the heating and punching device accurately and reliably.

Further, the stamp body 1 is locked by the locking surface 85b so that the left-right position is accurately set. Moreover,
Since the tactile cam 46 provided in the guide hole 44 in the recess 86 of the guide bar 83 is fitted and elastically urged by the spring 21, it is possible to prevent the position of the stamp body 1 from being displaced during perforation.

Further, the opening / closing door 75 and the cam body 91 are connected via the sector gear 76, the gear 98 and the head switching rod 89.
The thermal head 90 is configured to release downward until the stamp body 1 is mounted on the perforation mounting portion 71 and the opening / closing door 75 is closed. The thermal head 90 does not damage the stamp surface portion 33, and after the perforation is completed, the carriage 87 is moved until the thermal head 90 recedes from the stamp surface portion 33 to the left. Since it is not continuously pressed, it is possible to prevent ink from leaking from the printing surface portion 33. When the opening / closing door 75 is opened when the stamp body 1 after punching is removed, the thermal head 90 is released downward.
Even when the paper is taken out, the stamp surface portion 33 is not damaged.

When the stamp body 1 is mounted on the perforation mounting portion 71, the skirt member 6 is switched to the third position by the guide bar 83, so that the skirt member 6 is perforated when the stamp surface 33 is perforated. It doesn't get in the way.

Since the proximity switches 104 and 105 are configured to detect the width size of the stamp body 1, the size of the stamp body 1 will not be mistaken and a character string that does not match the size of the stamp face portion 33 will not be punched. . Further, the stamp body 1 has the guide member 7 in the mounting portion 71 for punching.
Since the guide portions 80 of Nos. 8 and 79 are supported by the engagement of the guide groove 15 of the grip portion 2, if the grip portions 2 have the same configuration, the punching mounting portion 71 has the narrow stamp body 1 with the same configuration. Since the wide stamp body 1 can also be mounted, the versatility is excellent.

The proximity switches 104 and 105 are used to detect the presence or absence of the stamp body 1, and the stamp body 1 is controlled so as not to move to the next operation unless the stamp body 1 is removed when the power is turned on or after the punching is completed. Therefore, it is possible to prevent the stamp body 1 that has been punched from being forgotten, and
