Description

DETAILED DESCRIPTION OF THE INVENTION [1] Industrial Application Field - This invention relates to a printing device used when issuing bills, checks, etc. using a computer, and usually prints characters and numbers to indicate the amount. This invention relates to a printing device that is capable of printing embossed characters.

Background of a technology - Conventionally, when issuing cash vouchers such as bills and checks, a check writer is used to print the amount of money in embossed letters with unevenness formed on the character pattern part of the paper, and the amount of the issued cash voucher is printed. Efforts are made to prevent tampering.

However, since the check writer manually inputs the amount data to be printed, it is not only inefficient but also prone to errors.

In addition to the amount, bills and checks have the date of issue and payment date written on them, and these are determined based on the financial plan.
If these recorded data are retrieved from the computer accounting system and automatically printed, office efficiency can be greatly improved and mistakes can be prevented from occurring.

-Prior Art- However, ordinary printers included in computer systems cannot print embossed characters, which causes problems in printing amounts on bills and checks. Therefore, a pair of a type ring 60 and a pressing pin 61 as shown in FIG. 4 is installed in the paper path of the printer device so that the amount can be printed while feeding the paper 62 in the longitudinal direction (in the direction of the arrow in the figure). A handprint printing device is used as an input/output device for electronic computers, and a wire dot impact type printing head is used to strike a wire at the same location on a sheet of paper many times to form unevenness in the character pattern area. have been proposed (for example, JP-A-58-104766, JP-A-59-29182).

Problems to be Solved by the Invention - Bills and checks are printed with information such as the drawer, payee, date of issue, and payment date, but other information other than the amount is usually printed in characters. Therefore, when the paper 62 is fed in the longitudinal direction as shown in Fig. 4 in order to print the amount in embossed letters, it becomes impossible to print items other than the amount in normal line units, and the image Since this is a printing process, the procedure for the printing process becomes complicated, leading to the problem that printing takes time.

In addition, the method of printing tamper-proof characters by repeatedly striking a wire at the same location cannot form clear irregularities on the paper like a check writer, so it is not necessarily satisfactory as a tamper-proof character. However, since the printing operation is performed many times on the same location, there is also the drawback that the printing process takes time.

This invention was made for the purpose of obtaining a printer device that can efficiently and automatically print bills, checks, etc. based on data from a computer. The purpose of the present invention is to obtain a printer that can print documents efficiently and can print ordinary documents efficiently.

Next, the operation during handprint printing will be explained. The handprint paper is stacked on the stacking stand 5 with the longitudinal direction perpendicular to the paper feeding direction, and like normal cut media, the handprint paper is separated one by one by a feed roller 7 and a separation roller 8 and sent to a normal character printing unit. The unit 2 prints the issuer, payee, issue date, payment date, etc.

The bill paper on which predetermined characters have been printed by the normal character printing unit 2 is sent to the holding roller 22 by paper feed rollers 17, 19, and 20. At this time, the embossed character printing unit 3 advances to the position shown by the imaginary line in FIG. 1, where the notch groove 24 for paper insertion coincides with the paper feeding surface of the holding roller 22 due to the rotation of the pulse motor 45. This position is detected by the position detection sensor 49 detecting the detection piece 47, and the pulse motor 45 is stopped by the detection signal of the position detection sensor 49.

The holding roller 22 continues to feed the paper, and after the photoelectric sensors 51 and 52 of the embossed character printing unit detect the leading edge of the paper, the holding roller 22 feeds the paper by a set feed amount and then stops. By changing the amount of paper feeding by the holding roller 22 after receiving the detection signals from the photoelectric sensors 51 and 52, the position where the amount is written in the vertical direction is set.

Next, the amount is printed in the embossed character printing unit 3 by the above-described operation, and after printing is completed, the holding roller 22 is reversed to pull out the paper from the embossed character printing unit 3. Next, the embossed character printing unit 3 is operated by a pulse motor 45.
As a result of the reverse rotation of the unit 3, the unit 3 is evacuated from the paper path and reaches the position shown by the solid line in FIG.
