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, a stamp body whose seal face is made of heat-sensitive stencil paper,
The present invention relates to a stamping device provided with a heat punching device for forming a hole in the stamp face of the stamp body.

[0002]

2. Description of the Related Art Conventionally, a stamp for printing a company name, an address, and various other character strings on the surface of a sheet is provided.
Various stamps having a stamp surface made of rubber are 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.
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 adhered to the lower surface of a base of a stamp member having a grip portion through a cushion material, and the heat-sensitive stencil printing paper 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 composed of a stamp member and a stencil printing plate. A stamp is obtained that can be printed over and over.

[0006] Further, the applicant of the present invention has disclosed in
In Japanese Patent Publication No. 78, a stamping device comprising a stamp body and a heat punching device for forming a hole in the stamp face of the stamp body was proposed. The stamp body includes a gripping portion, a main body case, a supply reel and a take-up reel provided in the main body case for supplying and winding a tape-shaped heat-sensitive stencil sheet, and a portion of the perforated heat-sensitive stencil sheet. And an ink pad for supplying ink to the printer.

[0007] The heating perforating apparatus includes a perforating mounting section for detachably mounting a stamp body, a feed mechanism for feeding a thermosensitive stencil sheet of the stamp body, and a perforation in the thermosensitive stencil sheet of the stamp body. It is composed of a thermal head, a keyboard for inputting characters and symbols, and a control device for controlling a feed mechanism and a thermal head so as to pierce a heat-sensitive stencil sheet with a character string input based on input data. ing.

According to the stamping device, 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 device. 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.

[0009]

However, in the conventional stamping device, since the heating punching device can always perform the punching operation, the punching operation is performed again on the stamp body in which the character string pattern has been punched in the stamp face portion. May be performed. In particular, this is likely to occur when the stamp body after the punching operation is directly attached to the heating punch without removing the stamp body.The next time the operator forgets to replace the stamp body when using the apparatus, the same operation is performed. In many cases, the punching operation is repeatedly performed on the stamp body.

[0010] The thermal head of the heat punching apparatus performs punching while pressing the stamp face of the stamp body. Therefore, when double punching of the stamp body is performed, ink oozes out of the previously opened punching pattern and adheres to the thermal head. If the thermal head is contaminated with ink, defective perforation is likely to occur, and in some cases, the thermal head may be damaged.

Also, of course, the fact that double drilling is performed violates the previously created drilling pattern.
The stamp body becomes useless.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to urge an operator to confirm a stamp body, and to prevent double punching of a stamp face due to an erroneous operation and contamination of a thermal head by ink. It is to provide a stamp device to prevent.

[0013]

In order to achieve this object, a stamping apparatus according to the present invention comprises a stamp body and a heating perforating apparatus for perforating a dot pattern on a stamp face of the stamp body. A heating unit for detachably mounting the stamp body; an input unit for inputting characters and symbols; and a data storage for storing input data input from the input unit. Means, a punching means including a thermal head for punching dots in a stamped surface portion of a stamp body mounted on the mounting portion for punching, and drive control for driving and controlling the punching means upon receiving input data from the data storage means. Means for detecting whether or not the stamp body is mounted on the mounting portion for perforation, and when the main power supply of the heating perforation device is turned on. Ku when drilling operation by the drive control means is completed, when the mounting detecting means detects the mounting of the stamp body, and a standby control means for said heating perforating device in a standby state.

It is to be noted that a warning means for warning that the stamp body is still attached during the standby state by the standby control means may be provided.

[0015] The warning means may be a display means for displaying a message prompting the user to remove the stamp body from the perforated mounting portion.

[0016]

In the stamp device of the present invention having the above-described structure, whether or not the stamp body is mounted on the mounting portion for perforation is detected by the mounting detecting means. Then, when the main power supply of the heating perforation apparatus is turned on or when the perforation operation by the drive control means is completed, and the mounting detection means detects the mounting of the stamp body, the standby control means causes the heat perforation to be performed. The device is put on standby.

Therefore, the operator is obliged to remove the stamp body, and inadvertently pierce the stamp body that is still mounted on the mounting portion for piercing, which may have been pierced with the dot pattern. Can be prevented.

The thermal head 90 includes the cam contact plate 93 and the spring 97
The stamp body 1 is disposed at a perforation position for pressing the right end of the stamp face portion 33 of the stamp body 1 shown by a solid line in FIG.

As described above, the operator operates the stamp body 1
After the is mounted, the perforation switch 66 is turned ON.

Next, when the perforation switch 66 is turned ON (S7: Yes), the detection signals of the proximity switches 104 and 105 are read (S8), and next, whether or not the stamp body 1 is present, that is, the stamp It is determined whether or not the body 1 is mounted on the mounting portion 71 for piercing (S9). When the determination is No, that is, when the operator operates the piercing switch 66 without mounting the stamp body 1, In S10, "Please attach a stamp body" is displayed on the LCD 53, and then the flow shifts to S7. On the other hand, the determination in S9 is Ye
In s, if the stamp body 1 is mounted, S11
, The stamp face size and stamp body 1 set in S5
It is determined whether or not the size is compatible. The size of the stamp body 1 means the proximity switches 104 and 105.
Is the width size of the stamp body 1 determined based on the detection signal from the stamp body 1.

Next, when the determination in S11 is No, that is,
If the size of the stamp body 1 does not conform to the set stamp face size, "Please replace the stamp body" is displayed on the LCD 53 (S12), and the process proceeds to S7. Steps S7 to S12 are repeatedly performed until the currently mounted stamp body 1 is removed and a stamp body 1 having a size matching the set stamp size is mounted.

On the other hand, when the determination in S11 is Yes, ie,
When the size of the attached stamp body 1 matches the set stamp face size, a punching process is performed on the stamp face portion 33 of the stamp body 1 and during the punching process, the LCD 53 is used.
Displays "drilling" (S13). In the punching process, first, dot pattern data for punching is created based on the format and character string data input to the input buffer 124 and stored in the punching buffer 125.
The carriage feed motor 100 is driven based on the dot pattern data stored in the perforation buffer 125, the carriage 87 moves from the position indicated by the solid line in FIG. 21 to the position indicated by the two-dot chain line, and the thermal head 90 is driven. Then, a perforation based on the perforated dot pattern data is formed in the stamp face portion 33.

At the end of drilling, the thermal head 90
Until the carriage 8 is displaced leftward from the stamp face 33.
7 is driven to move, so that the thermal head 90 does not continue to press the stamp surface portion 33, thereby preventing the ink from leaking. Next, in S14, it is determined whether or not the perforation has been completed. When the perforation has been completed, in S15, "End of the perforation process" and "Please remove the stamp body" are displayed on the LCD 53,
The process returns to S1. Note that the LCD 53 and S15 of the above processing steps correspond to the warning means of the present invention, and particularly correspond to the display means therein. Looking at the display of "Please remove the stamp body", the operator opens the opening / closing door 75,
Remove the stamp body 1. At this time, since the carriage 87 has moved to the position shown by the two-dot chain line in FIG. 21, the carriage 87 and the thermal head 90 do not prevent the removal of the stamp body 1.

If the stamp body 1 is not removed, the processing steps S1 to S3 corresponding to the standby state of the present invention are repeated until the stamp body 1 is removed.

Next, the operation of the stamp device including the stamp body 1 and the heating and punching device 50 described above will be described.

With respect to the stamp body 1, a large number of perforations having a desired pattern are formed in advance on the heat-sensitive stencil sheet 28 forming the stamp face portion 33, the protective cap 7 is removed, and the stamp face portion 33 is attached via the skirt member 6. After positioning at a desired position on the surface of the paper, grasping the gripping portion 2 and pushing the gripping portion 2 downward, and pressing the stamp surface portion 33 against the surface of the paper, the ink in the impregnating body 27 pierces a large number of holes. To permeate, the perforation pattern can be printed on the surface of the paper.

An up-and-down skirt member 6 surrounding the outer periphery of the stamp section 3 is provided, and the skirt member 6 is attached to the first
The skirt member 6 is configured to be able to move up and down over a position, a second position, and a third position.
Since the elastic member is elastically biased toward the first position, a desired pattern can be perforated in the stamp face portion 33 in a dod pattern while the skirt member 6 is held at the third position.

When printing, the skirt member 6 is held at the first position, the skirt member 6 is set at the position on the surface of the paper to be printed, the stamp surface portion 33 is positioned, and When the is pressed, the spring 21 contracts and the skirt member 6 rises to the second position, so that printing can be performed accurately at a desired position. Then, when the pressing force on the grip portion 2 is reduced after printing, the return operation of the skirt member 6 to the first position promotes the peeling of the paper from the stamp face portion 33, so that the printing can be performed neatly on thin paper. can do. However, when printing is performed in a narrow frame on the surface of the sheet, printing can be performed with the skirt member 6 held at the second position or the third position by hand. When not in use, the skirt member 6 is moved to the first position by the urging force of the spring 21.
The stamp body 1 is supported by the skirt member 6 and the stamp face portion 33 can be protected.

Further, a heat-sensitive stencil sheet 28 which covers the surface of the impregnated body 27 in a fixed manner is provided on the stamp portion 3, and the heat-sensitive stencil sheet extending to the outer peripheral side of the base member 26 inside the skirt member 6. Since the outer peripheral holding member 5 surrounding the outer peripheral portion of the base paper 28 is provided, the outer peripheral portion of the heat-sensitive stencil 28 extending to the outer peripheral side of the base member 26 can be prevented from being damaged by the skirt member 6, and the impregnated body 27 can be prevented. Can be prevented from flowing out to the outside.

Further, since the protection cap 7 which covers the stamp face portion 33 of the stamp section 3 and which is detachably attached to the stamp section 3 is provided, the protection cap 7 enables the stamp face section when not in use. 33 can be prevented from being damaged and dust can be attached, and printing can be prevented from being performed at a position where printing should not be performed due to erroneous operation.

[0093] Regarding the heating and punching device 50, when the stamp body 1 is mounted on the mounting portion 71 for punching, the stamp body 1
It is supported by a pair of front and rear guide portions engaged with the pair of front and rear guide grooves 15, and is pressed backward by a pair of rollers 81 to accurately set the position of the stamp body 1 in the front and rear direction.

The stamp body 1 is locked by the locking portions 85 and locked at the ends of the pair of front and rear guide grooves 15, so that the position in the left-right direction is accurately set. Moreover,
Since one roller 81 is engaged with the engaging recess 16 of the stamp body 1, the position of the stamp body 1 does not shift during punching.

The opening / closing door 75 and the cam body 91 are linked via the sector gear 76 and gear 98 and the head switching rod 89, and the stamp body 1 is mounted on the perforated mounting portion 71 until the opening / closing door 75 is closed. Since the thermal head 90 is configured to be released downward, the stamp face 1 is not damaged by the thermal head 90 when the stamp body 1 is mounted. The carriage 87 is moved until it retreats leftward from the stamp surface 33.
Is moved, the thermal head 90 does not continue to press the stamp surface portion 33, so that leakage of ink from the stamp surface portion 33 can be prevented. When removing the stamp body 1 after the perforation, the opening and closing door 75 opens the thermal head 9.
Since 0 is released downward, the stamp face 33 is not damaged even when the stamp body 1 is taken out.

When the stamp body 1 is mounted on the mounting portion 71 for perforation, the skirt member 6 is switched to the third highest position by the guide bar 83. , Does not interfere with perforation.

Since the width size of the stamp body 1 is detected by the proximity switches 104 and 105, the size of the stamp body 1 is not mistaken and a character string that does not conform to the size of the stamp face portion 33 is not pierced. . Further, the stamp body 1 is provided with a guide member 78 in the mounting portion 71 for punching.
Since the gripping portion 2 has the same configuration, both the narrow stamp body 1 and the wide stamp body 1 can be mounted on the mounting portion 71 for drilling. Therefore, it is excellent in versatility.

Also, the presence / absence of the stamp body 1 is detected by the proximity switches 104 and 105, and control is performed so that the next operation is not performed 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 punch body 1 from being forgotten to be removed,
There is no double perforation.

In the above embodiment, the keyboard 52 corresponds to the input means, the heating punching mechanism 72 corresponds to the punching means, the control unit 110 corresponds to the drive control means and the standby control means, and the RAM 113 corresponds to the data storage means. I do.

Here, a part of the above embodiment can be changed as follows.

1) The mounting portion 71 for perforating the stamp body 1
Is mounted detachably from the right, but the stamp body 1 may be mounted detachably from above.

2) The heating perforating mechanism 72 is configured to perforate while moving the thermal head 90 via the carriage 87 while holding the stamp body 1 at a predetermined position. Alternatively, the stamp body 1 may be configured to be perforated while moving.

3] A solenoid actuator may be provided instead of the cam body 91, and the position of the thermal head 90 may be switched by the actuator.

4) The rack 92, drive gear 101,
Instead of the reduction gear mechanism 107, the carriage 87 may be driven to move in the left-right direction via a wire and a pulley.

5) Instead of the impregnating body 27, an ink body composed of a high-viscosity ink mass is used, and this ink body is mounted in the concave portion 25, and is raised to the same shape as the impregnating body 27. Is also good.

6] Instead of displaying a message prompting the removal of the stamp body 1 on the LCD 53 in the processing step S3 or S15, a buzzer or a vocalization device is provided, and the removal of the stamp body 1 is prompted by the sound of these. You may.
