The keyboard 40 includes various characters such as a character 42 such as a pseudonym or an alphabet and a stamp document creation key 46. Function keys.

Next, a control system of the stamp apparatus 1 will be described with reference to a block diagram shown in FIG. Input unit 10
Is connected to an input interface 58 of a microcomputer (control means, hereinafter abbreviated as a microcomputer) 56. The input interface 58 is connected to the bus line 60.
CPU 62, ROM 64, RAM (storage means) 6
6. It is connected to character generators (hereinafter referred to as CG-ROMs) 68 and 69 for thermal perforation and display of the base paper 20, and an output interface 70.

Here, the ROM 64 stores the stamp device 1
And a dictionary memory 72 used for kana / kanji conversion and the like. Further, the RAM 66 includes necessary counters and registers, including an input buffer 73, a thermal perforation buffer 74, and a shift register 75. Further, the CG-ROM 68 generates a dot pattern based on the input code data of the character, 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.
6. The stencil feed motor 32 and the display 14 are connected. Next, the head drive circuit 76 is shown in more detail in FIG. One electrode of each heating element 39 is connected to a +12 V power supply terminal 80, and the other electrode is connected to a heat perforation driver 82. The input terminal of each thermal drilling driver 82 is connected to an inverter 86 having an input connected to a thermal drilling strobe input terminal 84.

In such a control system, first, data corresponding to printing is stored in the shift register 75 in synchronization with a clock signal. Thereafter, when the latch signal is taken into the data latch circuit 90, the data recorded in the shift register 75 is output to the corresponding data latch circuit 90 and stored. At the same time, the data is applied to each thermal drilling driver 82. In this state, when a heat perforation pulse signal of logic "0" is applied from the heat perforation strobe input terminal 84 to the input terminal of the inverter 86, a signal of logic "1" is output from the output terminal of the inverter 86, The voltage is applied to the input terminal of the thermal perforation driver 82. Therefore, when the data of the data latch circuit 90 is logic "1", the output side of the heat perforation driver 82 becomes logic "0", and a drive current is supplied from the power supply terminal 80 to the corresponding heating element 39. You. At this time, the pulse width of the heat perforation pulse signal input to the heat perforation strobe input terminal 84 is set so that the surface temperature of the heating element 39 becomes a temperature suitable for heat perforation.

By the way, the stamp device 1 of the present embodiment is
By operating the stamp document creation key 46, in addition to creating a normal stamp document (hereinafter, referred to as a first stamp document), a stamp document (hereinafter, referred to as a second stamp document) having a band width of a heat-sensitive stencil sheet having a different width is used. Stamp original). That is, as shown in FIG. 9, the width of the band
Prepares two stamp sections 12A with different base papers
Then, one of the stamp sections 12A is selected, and the original creation section is selected.
12, the center line O in the width direction of the band of the base paper
And a second stamp using only the upper side or the lower side of the center line O.
Any of the stamp originals of the stamp original 20b is created by a character string input in advance. Here, in the stamp apparatus of the present embodiment, since the thermal head 16 is composed of 448 dots, when creating the second stamp document, a character string must be created in the upper half or the lower half (224 dots). become.

Hereinafter, an example of a stamp document creation program of the stamp apparatus 1 of the present embodiment will be described with reference to the flowchart of FIG. When the power is turned on, step S1
(Hereinafter, this is simply represented by S1; the same applies to other steps), initialization of each buffer, register, and the like in the RAM 66 and other initialization are performed. Character key 42
Is input to the input buffer 73 in steps S2, S3, and S4, and a character corresponding to the data is displayed in the CG-ROM for display in step S5.
It is displayed on the display 14 via 69. When the stamp document creation key 46 is pressed, the process goes to S7 through S2 and S6.
Is executed, and the dot pattern generated in the CG-ROM 68 for thermal perforation is developed in the thermal perforation buffer 74 in accordance with the input code data. Subsequently, the flow shifts to S8, where the dot pattern developed in the thermal punching buffer 74 is transferred to the shift register 75 for each dot row, and the dot row is thermally punched. By repeating S8 and S9 while judging whether or not all heat holes have been made based on the data to be heat-hole-formed in S9, the heating element array 38 is obtained.
448 dots of thermal perforation results over the entire length of

By executing the above-described printing program, the stamp apparatus 1 of this embodiment can heat-perforate a desired character string on the base paper, and the stamp unit 12A supplied with the hot-perforated base paper can be used as a document. A desired character string can be printed on the paper by taking it out of the creation unit 12B and pressing it on the paper as shown in FIG. In particular, in the stamp apparatus of the present embodiment, the original creating unit 12B can select a printing base paper of a desired size by thermally perforating the base paper 20 with a predetermined size without any influence. The stamp portion can be selected according to the size of the area to be printed, and the operability is good and the economy is excellent.

In the above embodiment, the heating element array 38 is constituted by 448 heating elements 39, but the number can be changed as appropriate. Further, the width of the heat-sensitive stencil sheet for heat-perforating the second stamp document is not limited to half the width of the heat-sensitive stencil sheet for heat-punching the first stamp document, and can be appropriately changed. is there.
