Abstract

PURPOSE:To enable everyone to easily form a printed manuscript by a method wherein ink is transferred to a recording medium using heat-sensitive stencil base paper which is thermally perforated in a pattern form. CONSTITUTION:Heat-sensitive stencil base paper 24 which is thermally perforated is fed in a direction D by stencil base paper feed rollers 22, 23. When a grip 13 of a stamp 12 is pressed toward the heat-sensitive stencil base paper 24 against the force of a spring 29, an ink pad 30 comes into contact with the heat-sensitive stencil base paper 24, and the heat-sensitive stencil base paper 24 adheres to the ink pad 30. In this state, the stamp 2 is extracted from a stamp holding part 17 of a main body 11 of an electronic stamp by gripping the grip 13 of the stamp 12. The stamp 12 is pressed against paper by gripping the grip 13, whereby the ink of the ink pad 30 is supplied to the heat-sensitive stencil base paper 24. Only the ink corresponding to the thermally perforated part of the heat-sensitive stencil base paper 24 reaches the paper and forms characters.

As shown in FIG. 1, the original creating section 16 is provided with a thermal head 19 as a heating means.
It is pressed against the platen roller 20. A heat-sensitive stencil paper 24 is pulled out between the thermal head 19 and the platen roller 20 by a stencil paper pull-out roller 21, and is sent by a stencil paper feed roller 22. The heat-sensitive stencil paper 24 that has been thermally perforated by the thermal head 19 is sent to the lower surface of the stamp 12 by stencil paper feed rollers 22 and 23.

[0012] The stamp body 28 of the stamp 12 is attached to a support part (not shown) with a gap 27 between the ink pad 30 and the stencil feed roller 23 in the stamp holding part 17.
It is supported by After the heat-sensitive stencil paper 24 is fed to the bottom surface of the stamp 12, when the handle 13 of the stamp 12 is pushed in the direction of the heat-sensitive stencil paper 24 against the spring 29, the ink pad 30 comes into contact with the heat-sensitive stencil paper 24. ,
The heat-sensitive stencil paper 24 sticks to the ink pad 30 due to the viscosity of the ink in the ink pad 30 .

The heat-sensitive stencil paper 24 is formed by adhering a thermoplastic film and a porous support, and the thermoplastic film side is in contact with the thermal head 19. Further, as shown in FIG. 3, heat-sensitive stencil paper 24
A frame 25 is adhered to.

The thermal head 19 includes a heat generating element array on its head body. The heating element row consists of a large number of heating elements, and in this example, 448 heating elements are arranged in one row.
Equipped with several heating elements. The heating elements are arranged adjacent to each other in a direction perpendicular to the feeding direction of the heat-sensitive stencil paper 24, and by driving the heating element array at a predetermined timing in accordance with the feeding of the stencil paper, the keyboard 10
The heat-sensitive stencil paper 24 is thermally perforated according to the data input in step . The thermally perforated heat-sensitive stencil paper 24 is fed by a predetermined amount by the stencil feed rollers 22 and 23 so that it comes to the lower surface of the ink pad 30.

Next, the control system of this electronic stamp will be explained based on the block diagram shown in FIG.

The keyboard 10 is connected to an input interface 58 of a microcomputer (hereinafter referred to as microcomputer) 56. The input interface 58 is connected to the CPU 62, ROM 64, and RAM 6 by a bus line 60.
6. Character generator (hereinafter referred to as CG-ROM) 68 for thermal perforation and display of the heat-sensitive stencil paper 24;

The RAM 66 includes an input buffer 73 for storing data inputted from the keyboard 10, a thermal perforation buffer 74 for storing data for thermal perforation of the heat-sensitive stencil paper 24, a shift register 75, and necessary counters and the like. Equipped with a register.

The CG-ROM 68 generates a dot pattern based on input character code data, and the CG-ROM 69 generates a display dot pattern to be displayed on the display 14.

A head drive circuit 76, a motor drive circuit 77, and a display drive circuit 78 are connected to the output interface 70, and the thermal head 19, paper feed motor 32, and display 14 are connected to each of them.

An example of the operation of creating a stamp document for the electronic stamp of this embodiment will be described below with reference to the flowchart shown in FIG.

When the power is turned on, step S1 (hereinafter referred to as
It is simply represented by S1. The same goes for other steps. ) with R
Initialization of each buffer register, etc. in the AM66 and other initial settings are performed.

First, a character string is input using the keyboard 10 while checking the input characters on the display 14. Thermal perforation data input using the character key 42 is
The data is stored in the input buffer 73 in steps S2, S3, and S4, and the character corresponding to the thermal drilling data is displayed on the display 14 via the display CG-ROM 69 in step S5. When the stamp manuscript creation key is pressed, S2,
S7 is executed via S6, and the dot pattern generated in the thermal perforation CG-ROM 68 in accordance with the input code data is developed in the thermal perforation buffer 74.

Next, the process moves to S8, and the thermal perforation buffer 74
The developed dot pattern is transferred one dot row at a time to the shift register 75, and the dot rows are thermally perforated on the heat-sensitive stencil paper. By repeating S8 and S9 while determining whether all the data to be thermally punched has been thermally punched in S9, a thermal punching result of 448 dots over the entire length of the heating element array is obtained. At this time, as shown in FIG. 1, the thermally perforated heat-sensitive stencil paper 24 is sent in the direction D by the stencil paper feed rollers 22 and 23.

When the thermal perforation of the character string is completed and the handle 13 of the stamp 12 is pushed in the direction of the heat-sensitive stencil paper 24 against the spring 29, the ink pad 30 presses against the heat-sensitive stencil paper 2.
4, due to the viscosity of the ink on the ink pad 30,
The heat-sensitive stencil paper 24 sticks to the ink pad 30. In this state, hold the handle 13 of the stamp 12 and place the stamp 12 on the stamp holder 17 of the main body 11 of the electronic stamp.
Pull out more. By holding the handle 13 and pressing the stamp 12 against the paper 35 in the E direction as shown in FIG. Only a portion of the ink reaches the paper 35 to form characters. The situation at this time is shown in FIG.

In the above embodiment, there are 44 heating element rows.
Although it was composed of eight heating elements, this number can be changed as appropriate.

When printing is completed and you wish to print other characters, peel off the heat-sensitive stencil paper 24 stuck to the ink pad 30 of the stamp 12 and set the stamp 12 in the stamp holder 17 of the main body 11 of the electronic stamp. , as described above, create a stamp manuscript. Furthermore, by storing the heat-sensitive stencil paper 24 after printing has been completed, it is possible to reuse the heat-sensitive stencil paper 24 at any time, which is economical since it is not necessary to make the heat-sensitive stencil paper 24 with the same printed content over and over again. It is also excellent in sex.
