[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamp device,
More particularly, the present invention relates to a stamping device including a stamp body having a stamped surface portion formed by covering the surface of an ink body with a heat-sensitive stencil sheet, and a heat punching device for punching the stamped surface portion of the stamp body in a dot shape.

[0002]

2. Description of the Related Art Heretofore, various stamps for printing a company name / address and various other 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, a desired dot pattern can be pierced by irradiating an infrared ray or a thermal head, and by penetrating ink from the perforation group, a heat-sensitive material that can be used for printing various patterns such as character strings, figures, and marks. A stencil sheet using a stencil sheet has been practically used.

As disclosed in Japanese Utility Model Application Laid-Open No. 5-74833, the applicant of the present application is a stencil printing plate mainly composed of the heat-sensitive stencil sheet and an impregnated body impregnated with ink. A stencil printing plate suitable for making a stamp instead of a stamp whose surface is made of rubber was proposed. This stencil printing plate 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. It is a configuration in which it 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 gripping portion via a cushion material, and the heat-sensitive stencil sheet is attached to a thermal head or the like. By punching a pattern such as a desired character string, a stamp formed of a stamp member and a stencil printing plate is printed on a sheet many times as in a normal stamp. You will get a stamp that you can do.

[0006] The applicant of the present invention has disclosed Japanese Patent Application Laid-Open No. Hei 4-2267.
As disclosed in Japanese Patent Publication No. 78-78, there has been proposed a stamping device including a stamp body and a heating perforation apparatus for forming a perforation in a stamp face of the stamp body. The stamp body is provided on a gripping portion, a main body case, a supply reel and a take-up reel which are provided in the main body case and supply and wind a tape-shaped heat-sensitive stencil sheet, and a portion of the perforated heat-sensitive stencil sheet. And an ink pad for supplying ink. Further, the heating punching device, a mounting unit for punching for detachably mounting the stamp body, a feed mechanism for feeding the heat-sensitive stencil sheet of the stamp body,

It is composed of a feed mechanism and a control device for controlling a thermal head so as to pierce a heat-sensitive stencil sheet with a character string input based on input data.

According to this stamp apparatus, a tape-shaped heat-sensitive stencil sheet is provided on the stamp body, and a desired character string pattern can be perforated on the stamp face of the stamp body by the heating perforating apparatus. Therefore, different patterns can be perforated on the stamp surface, and at the time of printing, ink is automatically supplied from the ink pad inside the stamp body to the stamp surface, so that external ink is applied to the stamp surface. Can be printed without the need.

[0008]

SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Application Laid-Open No. 4-226 is disclosed.
In the stamp body of the stamp apparatus of the '778 publication,
Although a long tape-shaped heat-sensitive stencil sheet is provided, usually only a very small portion of the heat-sensitive stencil sheet is used, so that waste of the heat-sensitive stencil sheet increases. In addition, since a long tape-shaped heat-sensitive stencil sheet, a supply reel, a take-up reel, and the like are provided inside the stamp body, the stamp body becomes large and difficult to use, and the manufacturing cost increases. Furthermore, since the ink pad is in contact with the tape-shaped heat-sensitive stencil paper, it is difficult to seal the ink pad so that the ink does not leak, and the ink is likely to leak.

For this reason, the applicant of the present application has filed Japanese Patent Application No. 5-329.
No. 657 (Japanese Unexamined Patent Publication No. 7-149034),
The present invention has proposed a stamping device including a stamping member capable of reducing the size, weight, and cost of the stamping member and preventing leakage of ink, and a heating perforation device capable of perforating the stamp face of the stamping member.

The stencil printing plate of the stamp body in this stamping device includes an ink body and a heat-sensitive stencil sheet which covers the surface of the ink body and forms a stamped surface portion. It is a small and lightweight configuration.
In addition, since the heat-sensitive stencil paper is configured to cover the surface of the ink body in a fixed manner, the ink does not leak to portions other than the stamp face. When the ink body is formed of an impregnated body impregnated with ink, the ink can be supplied during printing for an extended period of time without any excess or shortage.

However, the applicant of the present application has found the following problems in the case where the surface of such an ink body is fixedly covered with a heat-sensitive stencil sheet to form a stamp face. That is, for example, even if the ink body is formed in a substantially rectangular parallelepiped so that the stamp surface is flat, if the ink body is actually wrapped with the heat-sensitive stencil paper, the edges are rounded and compared to the center. For example, it is deformed as thin as about 0.5 mm. The reason for this is that the ink body needs to be oozed by being pressed, so that the ink body is often made of an impregnated body in which the ink is impregnated. In this case, the impregnated body is made of a resilient foam of a synthetic resin material. Therefore, when the impregnated body is wrapped with the heat-sensitive stencil paper, the edges are necessarily rounded.

[0012] Since the edge is rounded and deformed thinner than the center as described above, poor drilling is likely to occur at the edge when drilling with a thermal head. This will be described with reference to FIG. FIG. 25 shows the positional relationship between the stamp surface section 230 and the thermal head 290 during the punching operation. In brief, the configuration is such that a concave portion 2 of a rectangular parallelepiped hollow base member 226 having a shallow concave portion 225 on the lower surface side is provided.
25, an impregnated body 227 impregnated with oil-based ink is mounted. A heat-sensitive stencil sheet 228 covers the lower surface of the impregnated body 227 and the outer peripheral side of the base member 226, and the outer peripheral surface of the base member 226 with an adhesive 229. Adhered to. The part where the heat-sensitive stencil sheet 228 and the lower surface of the impregnated body 227 overlap is the stamp face part 230. In FIG. 25, in order to clarify the above-described deformation of the edge portion, the actual deformation degree is emphasized.

In FIG. 25, it is assumed that the thermal head 290 pierces while moving from the right end (state (A)) to the left end (state (C)) through the center (state (B)). In the central part shown in FIG.
Since the contact state between the (heat generating element) and the stamp surface portion 230 is normal, good perforation can be performed. In contrast, (A),
Since the contact state between the thermal head 290 and the stamp face portion 230 is shifted at both end portions shown in (C), even if the same perforation energy as in the central portion of (B) is applied, the thermal head 290 is not heated. The amount of heat applied to the stamp surface portion 230 is reduced, and the hole may not be normally drilled. Therefore, poor perforation is likely to occur at the edge.

[0014] Accordingly, the present invention provides a compact stamp body.
Provided is a stamp body that is made up of a stamp body that can be reduced in weight and cost and that can prevent leakage of ink, and a heating perforation apparatus that can perforate the stamped surface of the stamp body, and that can appropriately prevent poor perforation. With the goal.

A stamping device characterized in that during the perforation operation, the perforation energy for a predetermined portion at both ends of the stamp surface is increased by a predetermined amount than the perforation energy for a portion between the predetermined portions at both ends. is there.

It is conceivable that the ink body is constituted by an impregnated body impregnated with ink. Further, as the impregnated body, for example, as described in claim 6, it is conceivable that the impregnated body is made of a resilient foam of a synthetic resin material.

According to a second aspect of the present invention, the control means controls the voltage applied to the thermal head to thereby determine the perforation energy for a predetermined portion at both ends of the stamp surface during the perforation operation. 2. The stamping device according to claim 1, wherein the punching energy for a portion between the predetermined portions is increased by a predetermined amount.

The stamping apparatus according to claim 1, wherein the punching energy for the predetermined dot row and for the predetermined dot row before the end of the punching is increased by a predetermined amount compared to the punching energy for the dot row therebetween.

[0020]

According to the stamping apparatus of the first aspect having the above-described structure, the state in which the stamp body is mounted on the mounting portion for perforation of the heating perforating apparatus, and the input means is not used.
Characters or symbols are entered, the input data is
Stored in the storage means, the control means, the piercing means drive control and drilling control including thermal head receiving input data from the data storage means, for drilling in a dot shape to the stamp surface portion of the stamp body.

The stamp body having the perforated surface in this manner is taken out from the mounting portion for perforation of the heating perforator, and the gripping portion of the stamp body is gripped and the stencil printing plate is pressed against the surface of the paper. The ink of the ink body oozes out from the perforations of the heat-sensitive stencil sheet constituting the stamp face portion, so that a pattern such as an input character string is printed on the paper.

Here, the stencil printing plate of the stamp body is attached to a grip portion, and the stencil printing plate is composed of an ink body and a heat-sensitive stencil sheet that covers the surface of the ink body and forms a stamped surface portion. Therefore, the stencil printing plate has a simple, compact and lightweight configuration, and the production cost of the stamp body can be reduced. In addition, since the heat-sensitive stencil sheet is configured to cover the surface of the ink body in a fixed manner, the ink does not leak to portions other than the stamp face, and the ink can be supplied during printing for a long period of time.

Here, the control means of the present invention controls the thermal operation of the stamp body while relatively sliding the thermal head along the longitudinal direction of the stamp surface of the stamp body mounted on the mounting portion for punching. The punching operation is performed from one end to the other end of the stamp surface portion.During the punching operation, the punching energy for the predetermined portions at both ends of the stamp surface portion is smaller than the punching energy for the portion between the predetermined portions at both ends. It has been increased by a predetermined amount.

At the two end portions shown in FIGS. 25A and 25C, the contact state between the thermal head 290 and the stamp surface portion 230 is shifted, so that the same perforation energy as in the central portion of FIG. Is applied, the amount of heat applied to the stamp surface portion 230 from the heating element of the thermal head 290 is reduced. However, in the present invention, the perforation energy at both ends shown in FIGS. Since the energy is increased by a predetermined amount from the perforation energy at the center, the thermal head 290
Even if the contact state between the stamp surface portion 230 and the stamp surface portion 230 is deviated, the hole can be normally punched, thereby preventing poor drilling at the edge.

In order to increase the perforation energy for a predetermined portion at both ends of the stamp surface by a predetermined amount as compared with the perforation energy for a portion between the predetermined portions at both ends, for example, a thermal head for the thermal head may be provided. The control may be performed by controlling the applied voltage, or the control may be performed by controlling the application time to the thermal head. Note that the degree of increase in the drilling energy may be appropriately set according to how thinly the edge is deformed compared to the center.

When the punching operation is performed in a unit of one dot row from one end to the other end of the stamp surface of the stamp body, a predetermined dot row from the start of the punching operation during the punching operation and a predetermined operation before the end of the punching operation. The perforation energy for the dot rows may be increased by a predetermined amount compared to the perforation energy for the dot rows between them. In this case, control can be facilitated because the dot row can be used as a reference.

The control means moves the thermal head so as to relatively slide along the longitudinal direction of the stamp surface of the stamp body mounted on the mounting portion for perforation. Perforations may be made while the body is fixed and the thermal head is moved, or conversely, the thermal head may be fixedly provided and the holes may be made while moving the stamp body.

In the punching process shown in FIG. 24, first, the line counter value C is set to "0" (S210), and the numerical range of the line counter value C that is incremented each time a dot row is punched is S220. Determined in S230,
The application time according to the determination result is set in S240 to S260.

More specifically, first, in S220, it is determined whether or not the line counter value C is within the range A, and if it is within the range A, the application time is set to Ta (S240). Also,
If the line counter value C is not within the range A (S220:
NO), In S230, it is determined whether or not it is within the range B,
If within the range B, the application time is set to Tb (S2
50). If the line counter value C is neither within the range A nor the range B (S220: NO, S230: N
O), the application time is set to Tc (S260).

The ranges A to C and the application times Ta, Tb,
Tc will be described. The ranges A to C correspond to the areas indicated by A to C in FIG. In the present embodiment, 20 dot rows at both ends of the stamp face portion 33 correspond to each other. If the total number of dot rows is 495, the first dot row to the twentieth dot row are used.
The range up to the dot row is the range A, from the 21st dot row to the 47th dot row.
The range B is up to 5 dot rows, and the range C is from 476 dot row to 495 dot row.

The application times Ta, Tb, and Tc are set so that the application times Ta and Tc corresponding to the ranges A and C are longer than the application time Tb corresponding to the range B. In this embodiment, for example, Ta is used. = Tc = 6ms and Tb = 4
ms. Returning to FIG. 24, in S270,
The perforation is performed according to the application time Ta or Tb or Tc set in any of S240 to S260.

Then, it is determined whether or not the current line is the last line (S280). If it is not the last line, the line counter is incremented in S290 and the process returns to S220. On the other hand, if it is the last line (S280: YES), the present process is temporarily ended, the process returns to the main process of FIG. 23, and shifts to S140.

As described above, in this embodiment, the thermal head 90 is slid along the longitudinal direction of the stamp face portion 33 of the stamp body 1 mounted on the mounting portion 71 for perforation.
The punching operation is performed from one end of the stamp face portion 33 of the stamp body 1 to the other end, and the punching energy is applied to predetermined portions (ranges A and C in FIG. 6) at both ends of the stamp face portion 33 during the punching operation. Is increased by a predetermined amount from the perforation energy for the portion therebetween (the range B portion in FIG. 6). Specifically, the application time Ta, T for the range A, C portion is shorter than the application time Tb for the range B portion.
This is realized by making c longer.

As a result, the contact state between the thermal head 90 and the stamp surface portion 33 is shifted at both end portions of the stamp surface portion 33 indicated by A and C in FIG.
Since the perforation energy is increased more than the portion B, the amount of heat applied from the heating element of the thermal head 90 to the stamp face portion 33 becomes substantially equal in the entire range. Therefore, even if the contact state between the thermal head 90 and the stamp surface portion 33 is shifted, it is possible to perform the perforation normally and prevent the defective perforation at the edge portion.

The predetermined portions (A,
To increase the drilling energy for C)
As shown by 4, the application time to the thermal head 90 may be controlled, or the voltage applied to the thermal head 90 may be controlled.

For example, S240 to S260 in FIG.
Are applied to the applied voltages Va, Tb, and Tc, respectively.
What is necessary is just to change to Vb and Vc. In this case, the range A,
The applied voltages Va and Vc corresponding to C are set higher than the applied voltages Vb corresponding to the range B.

In the above embodiment, the impregnated body 27 corresponds to an ink body, and the impregnated body 27 and the heat-sensitive stencil sheet 28 correspond to a stencil sheet. The keyboard 52 corresponds to an input unit, and the heating perforation mechanism 72 corresponds to a perforation unit.
