Abstract

PURPOSE:To make it possible to set properly the number of digits for test printing in accordance with the width of a printing paper by a method wherein the output of a printing digit setting section having a digit number setting means and a digit setting control circuit is inputted to a test control circuit. CONSTITUTION:A printing digit setting section 12 is provided with the digit number setting means 13 for setting the number of digits for test printing and the digit number setting control circuit 14 capable of generating a digit number signal S5 designating the number of digits for test printing types to be written in a printing memory 9, by receiving a setting signal S4 from the digit number setting means 13. With the above arrangement, when the digit number signal S5 from the printing digit setting section 12 is inputted to the control circuit 11, characters to be test-printed are written in the printing memory 9 by a designated number of digits. Then, when the characters are test-printed by the designated number of digits, the control circuit carries the printing paper and controls a printing control circuit 8 so that the like test printing is performed in the next line.

Description

Detailed Description of the Invention α) Technical Field of the Invention The present invention provides a printing device having a dust printing function.
The present invention relates to a printing device that can appropriately set the number of digits for test printing depending on the width of printing paper such as a form.

■ Prior Art and Problems Some printing devices that print the output results of electronic computers as characters have a test printing function in order to adjust the printing position in the digit direction and digit direction of printing paper such as forms. However, in conventional printing devices, test printing is performed over all digits from the 1st digit to the 136th digit 1, for example, regardless of the paper width of the printing paper. Here, it is fine if the paper width is wider than all the digits mentioned above, but if it is pinched, the printing hammer will hit the llLMk type through the ink ribbon.
Damage such as breakage or missing parts may occur to the printing hammer and type. As a result, printed characters may become unclear or
There was a problem that made it impossible to print.

@Purpose of the Invention The present invention has been made in response to the above-mentioned circumstances, and an object of the present invention is to provide a printing device that can appropriately set the digits of dust printing depending on the width of the printing paper. do.

(a) Invention O*g And this purpose is to write the characters to be test printed into the printing memory by means of the dust control circuit, and to detect which character is in front of the printing hammer by means of the character code generator. , a printing device having a printing control circuit for issuing a test printing command by comparing the printing pattern with a signal from a type code generator; and a means for setting the number of digits for test printing; A print digit setting section is provided having a digit setting control circuit that generates a digit number signal specifying the number of printed characters of the test print written in the print memory according to the setting signal, and the output of the printing digit setting section is sent to the dust control circuit. This is achieved by providing a printing device characterized in that it has a K input function.

(2) Embodiment Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached figure m.

In the drawing, on the outer circumferential surface of a type belt 1, type characters 2 are arranged in a pairwise order. In front of the character belt 1, printing hammers 3 for example from the 1st digit to the 136th digit are arranged in a row to face it. An ink ribbon 4 runs along the type belt 1 and is connected to the type belt 1 and the printing handle ff3.
K so that the printing paper 5 of the form that is in contact with the paper and has an appropriate paper width runs in a direction perpendicular to the direction in which the type belt 10 rotates.
It has become. Then, according to the rotation of the type belt 1,
According to the address of the type 2 on the type belt 1, the type 2
Detects the position of the printed character 2 by the big array 17 of the printed character code generator 6, and receives the printed character code signal Sl sent from the printed character code generator 6 and the printed character signal S2 of the printed character 2 written in the printing memory 9. The printing control circuit detects that the type 2 to be printed is at the position of the printing hammer 3 of the digit O to be printed, and sends a printing command 83 to the drive circuit 1o to drive the corresponding printing hammer 3 to print. .

A test control circuit 11 is connected to the print control circuit 911 and the print memo 911 . This test control circuit 11
Fi, characters to be test printed in the print memory 9, e.g. tf
f) At the same time as writing 14, when the test printing starts, press the above rHJ - When all the lines are printed, feed the paper and print the next line, then repeat the KIK feed and perform the test printing. It controls the printing control circuit S. In addition to the provision of the DEDT control circuit 11 in this manner, the printing device has a DESC H3D character function.

In the present invention, the test control circuit 11 is further provided with a print digit setting section 12. This printing digit setting section 12 is used to appropriately set the number of digits for test printing according to the paper width of the printing paper 5.
13 and a digit setting control circuit 14. The number of digits setting means 13 is for appropriately setting the number of digits to be test printed, for example, by using a digital switch from the first digit to l113.
You may be able to set any number of digits using the G-digit tube, or you may use a one-switching system, such as 30, 60, 90, or 136 digits, depending on the number of times you hit the test print key on the operator panel. Alternatively, when setting the printing paper 5 in the printing section, the paper feeding sprocket is moved left and right according to the paper width, but the movement of this sprocket is detected by an appropriate sensor and the paper feed sprocket is moved to the left and right according to the paper width. K may be configured to automatically set the corresponding number of digits. The digit setting control circuit 14 receives the setting signal Sat from the arithmetic numeral setting means 13 and sends a digit number signal 8s that specifies the number of digits when writing test print characters, such as rHJ, written in the printing memory 9. It is something that is sent out.

Therefore, when the number-of-digits signal 8 = is inputted to the guest control circuit 11 from the printing digit setting sections 1 and 2, the printing character "H" to be test printed is stored in the print memory 9 with the specified number of digits, for example 9.
0 digits are written.

Note that a space symbol is written in the 91st to 136th digits @box. Then, when test printing is started next, the test control circuit 11 executes the above-mentioned [[Hj] after printing up to the 90th digit, feeds the paper and prints it to the line ``R)IJ t 90''.
The printing control 911 s is controlled so that the printing is performed in the digits and then the next paper is fed in the same manner as K11 to proceed with the dust printing.

(See) Effects of the Invention Since the present invention is constructed as described above, the digit a for test printing can be appropriately set depending on the paper width O of the printing paper 5. Therefore, even if the paper width is narrower than all the digits of the printing device, it is possible to prevent the printing hammer 3 from hitting the first class type 2 through the ink ribbon y4, and the printing/'
It is possible to prevent damage such as breakage or twisting of the 17 machine 3 and the type 1 from occurring. From this, it is possible to eliminate problems such as printing characters becoming unclear (printed characters become unclear) and printing impossible.
