Abstract

(57) [Summary] [Purpose] To enable a printer to automatically detect the position of printing paper and print accordingly, whereas conventionally the user had to manually position the printing paper in the horizontal direction. [Structure] A print paper detector 14 is mounted on the printer head 13, and the print head movement drive unit 15 is controlled by the position detection information of the print paper detector 14, so that the printer determines the print position in the horizontal direction. be.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to printers, and in particular to automatic position detection of printing paper and control device for printing position. Regarding.

0002

[Conventional technology]

Conventionally, in printers commonly used for office and other purposes, printing paper The user can manually position the left and right positions according to the printing paper being used. This moves the feeder, which moves the print paper in the left and right direction. The method used was to set the location.

0003

[Problem that the idea aims to solve]

With such conventional printers, for example, printers with a large number of print digits can be When printing after replacing new paper, the user must record the position in advance. You have to either record it and adjust it, or actually print it out and adjust it. There was a certain annoyance.

0004 The purpose of this invention is to solve the above problems and provide a printer that is easy to operate. Our goal is to provide the following.

[0005]

[Means to solve the problem]

The configuration of the printer device of this invention allows the use of multiple types of printing paper with different widths. In a printer equipped with a printing device, a printing paper position detector and a printing paper position detector are provided. The position of the printing paper is memorized by the output of the detector, and the position of the printing paper is stored at the time of printing. Therefore, it is characterized in that it includes a control section that performs the printing.

【Example】

FIG. 1 is a block diagram showing the functions of a printer according to an embodiment of the present invention.

[0007] In FIG. 1, in this embodiment, a print paper position detector 1 is installed in the print head. ing. The control section 2 controls the operation of each section based on signals from each section. print head The movement drive unit 3 moves the print head in the horizontal direction by driving a motor. Let's do it. The interface section 4 receives print data, control signals, etc. from other devices. Powered. The operation unit 5 receives a control signal from the user.

[0008] 2 is a front view of the printer shown in FIG. 1, and FIG. 3 is a side view of the printer shown in FIG.

[0009] 2 and 3, in the tractor feeder of this embodiment, the mounting bases 6, 1 0 is fixed to the main body of the printer apparatus and supports the main body of the tractor feeder. Pillar 8 , 11 guide the tractors 7 and 9 to move the printing paper in the horizontal direction. You can decide the position of

0010 The platen 12 feeds paper in conjunction with the tractors 7 and 9. Print head 13 , a print head movement drive section 15. The print paper position detector 14 detects the position of the print paper. Detect the left end position. Note that FIG. 3 shows the state in which the printing paper 16 is set. .

[0011] Next, the operation will be explained. First, the user presses the select switch on the operation panel 5. When the data is ready for data reception, the print head movement drive unit 15 moves the print head 13 is moved in the horizontal direction, the left edge of the printing paper is detected, and the information is transmitted to the control section 2.

0012 The control unit 2 memorizes this position and thereafter recognizes this position as the left edge of the printing paper 16. , determine the printing start position and print. Detection of the left edge of this printing paper 16 and Memorization is performed each time the select switch is pressed.

[0013] FIG. 4 is a front view showing a printer according to another embodiment of the present invention.

[0014] In FIG. 4, unlike the previous embodiment, the printer of this embodiment has a print head 1. A print position detector 17 is also attached to the right side (when viewed from the back) of 3. This results in , the right edge of the printing paper 16 is also detected and notified to the control section 2. The control unit 2 in FIG. The position is memorized, and if the data of the number of printing digits exceeds the printing range and is printed to the right. If it is sent, a line break will be performed so that it fits within the printing range. In this way, printing Controls the head movement drive section 15.

[0015]

[Effect of the idea]

As explained above, the present invention uses a mechanism that detects the position of printing paper to The printer automatically adjusts the print position, so the user does not have to worry about the position of the print paper as before. This has the effect of eliminating the trouble of adjusting.
