Abstract

<P>PROBLEM TO BE SOLVED: To provide a means for stamp-printing a letter, a picture, a line drawing or the like in one shot without requiring a transfer ribbon, at an improved printing speed. <P>SOLUTION: A pin dot printer freely changes printing contents by arranging a plurality of finely-divided pin dot stamps and controlling pin dots. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

    The present invention relates to a pin-dot printer that performs the same function as a printer by using a stamp system in which a sponge pad in which ink is impregnated in a print pin is used without using a ribbon.

  Conventional dot printers usually control 5 to 8 pins made of metal or the like, and simultaneously move the paper in synchronism to form characters to enable printing of multiple sheets. However, since the transfer ribbon is required as an indispensable condition, the running cost is high and the maintenance is complicated. In addition, the noise caused when the pins add impact shots to the ribbon is also subject to stress within the printer usage environment.

  Therefore, in the present invention, a single bubble sponge is attached to the tip of the printing dot pin, ink is impregnated into the sponge, and stamp printing is directly performed on the paper by controlling the dot pin, so that it has a function equivalent to or better than a general-purpose printer such as characters. The present invention provides a pin-dot printer that is made possible.

  By providing a large number of subdivided pin dots and controlling the pin dots, a single character, picture, line drawing or the like can be formed and then stamp printing can be performed in one shot.

  As described above, the pin dot stamp printer of the present invention improves the printing speed by stamp printing a plurality of characters etc. in one shot by controlling a large number of subdivided pin dots, and it is noiseless pin dots close to zero. Provide a stamp printer.

BEST MODE FOR CARRYING OUT THE INVENTION

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a side view of the embodiment. FIG. 2 shows an example of a pin dot stamp. In other words, the pin dot stamp block 2 shown in FIG. 1 is composed of 126 stamp pads and a plunger magnet 11 and a slide pin 13 that move the stamp pad 12 up and down in the example shown in FIG. FIG. 3 is a plan view of the pin dot stamp block 2.

  As shown in FIG. 3, each stamp block 14 is composed of six rows of stamp pads 12, that is, 36 stamp pads 12. The pin dot stamp block 2 shown in FIG. 1 is composed of six stamp blocks 14A to 14F shown in FIG. 4, and 216 stamp pads 12 form characters and the like.

  Details of the stamp print operation will be described. As shown in FIG. 5, the subdivided stamp pad 12 includes a plunger magnet 11 connected to the slide pin 12. When a print command signal SG necessary for forming characters indicating the drive circuit system in FIG. 6 is input to the arithmetic circuit 17, the stamp pad 12 necessary for stamp printing is connected to the plunger magnet 11 and the driver 15 as shown in FIG. A voltage is applied through and pushed down to length L. That is, a character or the like is formed by the stamp pad 12 pushed down by the print command signal SG.

  The print command signals S1 to S216 to the stamp pads 12 of the stamp pad group shown in FIG. 4 are necessary for forming characters or the like, that is, 14A-X1a to Xlf to 14A-X6a to X6f shown in FIGS. Further, 216 stamp pads 12 of 14F-Xla to Xlf and 14F-X6a to X6f are operated to form characters and the like.

  As an example, the print command signal shown in FIG. 6 is only applied to the portion where the black pad is formed on the stamp pad 12 print row 1P of each of the stamp blocks 14A to 14F at the place where the characters shown in FIGS. Is granted. When the 1P print formation is completed, a stamp command ST is given to the vertical slide drive unit 5 in order to stamp-print the print row 1P as shown in FIG. The pin dot stamp block 2 is lowered by the movement amount of T through the vertical slide part 4 by the stamp command ST, and 1P row is stamp printed on the paper 8. Thereafter, the stamp command ST is turned OFF, and the pin dot stamp block 2 is returned to the original position.

  When printing of the 1P row shown in FIGS. 7 and 8 is completed, the paper feed motor 19 is rotated and the paper feed roller 18 is rotated. The paper 8 pressed against the paper feed roller 18 is turned to a position where the 2P row can be stamp printed.

  The series of operations described above are performed until the 6P row is completed in the print row shown in FIGS. That is, by repeating line feeds as in a general-purpose printer, it is possible to freely print stamps necessary words, pictures and line drawings.
