When N pieces of print data and print command commands are received, the carrier is moved to the left end, and then the output of the image reading sensor is stored in the memory while moving the carrier to the right, and the contents of the memory are Refer to the position X1 of ruled line 1, which is the vertical line on the left side of the writing area on the paper, and the ruled line 2, which is the vertical line on the right side of the writing area.
, the received character string is edited with the print embossing position set as X1 and the character pitch as (x, -x1)/N, and printing is executed after editing is completed.

[Industrial application field]

The present invention uses vertical lines on the left side (
This invention relates to an equal allocation control method that detects the positions of a ruled line (1) and a vertical line (ruled line 2) on the right side, and allocates N characters to be printed equally between ruled line 1 and ruled line 2.

[Conventional technology]

On the paper, a rectangular frame is drawn with lines to indicate the area where characters and pictures can be written. Ruled line 1 (vertical line on the left side of the square frame)
In order to evenly allocate the N characters to be printed between the and ruled line 2 (vertical line on the right side of the square frame), conventionally, the programmer measured the distance from ruled line 1 to ruled line 2 each time, and The distance between the characters was calculated by calculating the number of characters to be used, and the distance between the characters was specified in the application program.

[Problems to be Solved by the Invention] In the prior art, each time a programmer creates an application program, he must find the distance between ruled line 1 and ruled line 2, and calculate the distance between characters based on this distance and the number of characters. This required a great deal of effort and time.

The present invention was created in view of this point, and an object of the present invention is to provide a printer device having a function of evenly allocating characters between ruled lines 1 and 2.

[Means for Solving the Problems] FIG. 1 is a diagram showing the principle of the present invention. The printer of the present invention includes:
It includes a printer mechanism section having a carrier 1 on which an image reading sensor 2 and a print head 3 are mounted, and a printer control circuit having equal allocation control means.

The equal allocation control means moves the carrier to the left end when N print data and print command commands are sent from the main unit, and then stores the output of the image reading sensor in the memory while moving the carrier to the right. and calculate the position x 1 of ruled line 1, which is the vertical line on the left side of the writing area on the paper, and the position x 2, of ruled line 2, which is the vertical line on the right side of the writing area, by referring to the contents of the memory. , the received character string is edited with the print embossing position set to the X character pinch (X2 - X+)/N, and printing is executed after the editing is completed.

FIG. 3 is a diagram showing the sensor output value when the image reading sensor is moved, and FIG. 4 is a diagram showing the moving distance between the ruled line of the paper and the image reading sensor. A rectangular frame is drawn with lines on the paper, and letters and pictures are written inside this frame. The vertical line on the left side of the square frame is called ruled line 1, and the vertical line on the right side of the square frame is called ruled line 2. When detecting the positions of ruled line 1 and ruled line 2,
The carrier is positioned so that the image reading sensor 2 is located further to the left from the left end of the paper, the carrier is moved rightward from this position, and the carrier is stopped at the position where the image reading sensor 2 crosses the ruled line 2.

The output values of the image reading sensor 2 are read while the carrier is moving rightward, and the left end position of the paper, the position of ruled line 1, and the position of ruled line 2 are determined based on the sequence of read output values.

■ Set equal allocation mode. The equal allocation mode can be set by a command from the main device or a key operation on the operation panel.

■ The characteristics of the print data sent from the main device and the number of print data sent (N pieces) are sequentially stored in the memory, and when a print command is received, the carrier is moved to the left end.

■ Move the carrier to the right.

■ Write the output value of the image reading sensor to RAM in synchronization with the dot pulse.

■ Refer to the RAM and check whether ruled line 2 has been found. If Yes, proceed to ■; if No, return to ■.

■ Start slowing down the carrier.

■ From the sensor output value written in the memory, set the memory address where the output starts to decrease to the minimum as the left edge of the paper, and then mark the memory address where the sensor output becomes thicker (and become the apex) with ruled line 1. Then, the memory address that will increase again and become the vertex is marked on the border 2.
