Description

Detailed Description of the Invention - Field of Industrial Application - This invention relates to a printing device used when issuing bills, checks, etc. using an electronic computer. This invention relates to a printing device that is capable of printing embossed characters.

-Technological Background- Conventionally, when issuing cash vouchers such as bills and checks, the amount is printed in embossed letters with unevenness on the character pattern part of the paper using a check writer, 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 include the issue date and payment date, which are determined based on the financial plan, so these data can be extracted from the computer accounting system and automatically printed. By doing so, 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 repeatedly hit the same spot on the paper with a wire to form unevenness in the character pattern. has been proposed (for example, JP-A-Sho
No. 58-104766, Japanese Patent Publication No. 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 letters. Then,
If 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 an image printing process is required. , a problem arises in that the printing process becomes complicated and 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.

-Means for Solving the Problems- In order to achieve the above object, the printer device of the present invention has a structure that feeds bills and check paper in a direction perpendicular to its longitudinal direction, and from a paper feed section to a paper discharge section. Two sets of printing units, a normal character printing unit 2 and an embossed character printing unit 3, are provided in the paper path leading to the paper.

It has a press-contact mechanism 30, and can print a multi-digit number in embossed letters in one operation. This embossed character printing unit 3 has a paper guide 4 on the back of the frame.
3 is attached, and is provided in the paper path of the printer device so as to be freely advanced in the vicinity of a holding roller 22 having a feeding function, which is provided in the paper path.

-Operation- When printing embossed characters on the fed paper, the embossed character printing unit 3 is advanced into the paper path, the fed paper is held by the holding roller 22, and the embossed character printing unit 3 is cut. Notch groove 2
4, print the embossed characters,
After printing, the holding roller 22 is reversed to pull out the paper from the notch groove 24, and then the embossed character printing unit 3 is evacuated from the paper path, and the holding roller 22 is rotated again to attach it to the back of the embossed character printing unit 3. The paper is discharged along the paper guide 43. Further, when printing only normal characters, the embossed character printing unit 3 is held in a retracted state from the paper path, and the paper passes through a paper guide 43 provided at the back of the embossed character printing unit.
