Abstract

PURPOSE:To provide an electronic equipment equipped with a printer which enables accurate positioning of a printing head at the printing position predetermined on a form or the like by mounting a gauge plate with a window at a specified visible position of the printhead section to check the printing position. CONSTITUTION:A gauge plate 19 is mounted at the tip of a printhead 14 together with a ribbon guide 17. The gauge 19 is provided with a window 20 at the position separated by a distance X above and by a distance Y sideways from the point of the head wire of the printhead 14 to check the printing position. The size of the window shall be just equivalent to one printing character. The printhead 14 is moved to printing positions on a form paper or the like beforehand and the addresses thereof are momorized. When actually printing data, deviations X and Y between the window 20 and the printhead 14 respectively are corrected.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to electronic equipment including a printing device, such as an electronic accounting machine.

[Technical background of the invention and its problems] For example, in electronic accounting machines, it is possible to print information such as data using a slip whose printing position is fixed in advance by grids, etc. To perform this printing, it is necessary to program the print head in advance so that it can be moved to a predetermined position.

Conventionally, when presetting such program data, the print head is set at the print position and the print head position information is input.

However, when the print head is directly set at the print position in this way, the print position is hidden by the print head and cannot be seen visually, making it difficult to set the print head correctly at the print position. It is not possible to confirm whether the printer is in use, and there is a problem that the print head and the print position are misaligned, making it difficult to see on a slip or the like.

[Purpose of the Invention] This invention was made to solve these problems, and provides a printing method that allows accurate positioning of the print head with respect to a predetermined printing position and that enables good printing of information on slips and the like. The purpose is to provide electronic equipment equipped with the device.

[Summary of the Invention] The present invention provides an electronic device equipped with a printing device that prints information while controlling the movement of the print head to a predetermined printing position based on preset program data. A gauge plate with a window for confirming the print position is installed at a predetermined visible position, and when setting program data to control the movement of the print head to the predetermined print position, data is set while moving the window to the print position. When printing information, the program data for the movable control unit is corrected using the distance between the print head and the window as a correction value, and the information is printed by the print head.

FIG. 6 shows part of the processing that the cPU 21 performs based on the ROM 22 (7) program data, and this processing involves reading information from the disk 32 of the external storage device 5 and performing predetermined processing. After that, the process of moving the print head 14 is started. At this time, it is checked whether the changeover switch is set to "business execution". "Business execution"
If so, the movement information of the print head 14 is corrected.

For example, if the movement information of the head 14 is xly, this correction is made to X+X and V+Y. That is, when setting the movement information of the print head 14 in advance, the print position is checked using the window 20 of the gauge plate 19, and for this reason, the address of the set print position information and the actual print head 14 are Since the position is shifted by a distance X and Y, this correction is performed here so that the print head 14 is positioned at the correctly set print position. The corrected head movement information is output to the printing device 4 via the printer interface 30, and the movement of the print head 14 is controlled. Then, data is output to the printing device 4 at the timing when the print head 14 is located at the movement information position, and printing on the paper is performed.

In the apparatus according to the embodiment of the present invention configured as described above, the print head 14 performs the start positioning to start printing data.
This is done while moving the gauge plate 19, and alignment at that time can be done using the window 20 of the gauge plate 19. For example, when printing on slip paper, the data printing start position differs depending on the structure of the slip, and will be at discrete positions on the same line. Store the address of the print position. At this time, since the print positioning can be performed visually through the window 20, the positioning can be easily and reliably performed. Moreover, when actually printing data, window 2
Since the deviation distance 11 can be done. Therefore, for items such as slips in which a plurality of data printing start positions are set, position setting can be easily and reliably performed, and excellent effects can be obtained.

[Effects of the Invention] As detailed above, according to the present invention, the print head can be accurately positioned with respect to a predetermined print position,
It is possible to provide an electronic device equipped with a printing device that can effectively print information on slips and the like.
