Abstract

PURPOSE:To provide a printer capable of cleanly printing in the inside of borders on a paper through simplified data formation, by providing a rule sensor and printing while detecting borders on the paper. CONSTITUTION:In response to a vertical rule detecting command from a host computer 11, the rule sensor 14 is moved to a vertical rule detecting position by a printing-controlling part 13, line feeding of the paper is performed by a motor 16, a vertical rule is detected by the sensor 14, and the paper feeding is stopped. In response to a horizontal rule detecting command from the host computer 11, the sensor 14 is moved to a horizontal rule detecting position by the printing-controlling part 13, is moved on the paper together with a printing head 15 by the motor 16, and printing is started after detecting the horizontal rule. The sensor 14 is moved between the vertical rule detecting position and the horizontal rule detecting position by using a clutch or the like. The rule sensor 14 comprises a pair of a light-emitting part and a light-receiving part, and an electrical signal therefrom is varied on detection of a rule.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a printing device used in a word processor or the like.

2. Description of the Related Art Conventionally, there have been printing devices capable of printing characters as well as marking lines, but there has been no printing device that can print accurately along the marking lines of a sheet of paper on which the marking lines are printed.

Problems to be Solved by the Invention With the above-mentioned conventional printing devices, printing is performed on a sheet of paper with pre-marked lines specified by the destination of the document, so it is very time-consuming when creating data with a word processor, etc. There was a problem that it took a while.

The present invention is intended to solve these conventional problems, and aims to provide a printing device that can shorten data creation using a word processor or the like and can print neatly within the frame of a sheet of paper.

Means for Solving the Problems In order to solve all of the above problems, the present invention provides a marker line sensor and prints while detecting the frame of the paper.

Therefore, according to the present invention, by providing a sensor for detecting a marker line, it is possible to detect the marker line printed in advance, shorten the time required to create print data using a word processor, etc., and print data within the frame of the paper. , it has the effect of being able to print clearly.

Example The figure shows the entire configuration of an embodiment of the present invention.

In the figure, 11 is a host converter that controls the printing device, 12 is the printing device, 13 to 16 are inside the printing device,
Reference numeral 13 denotes a print control unit, 14 a marker line sensor, 15 a print head, and 16 a print head, a marker line sensor, and a plurality of motors for moving the paper. The marking line sensor 14 and the print head 15 are integrated.

Next, the operation of the above embodiment will be explained. In response to a vertical line detection command from the host conbeater 11, the print control unit 13 moves the line sensor 14 to the vertical line detection position, the motor 16 feeds the paper, and the line sensor 14 detects the vertical line. Detected and stops paper feeding. Further, in response to a horizontal line detection command from the host conbeater 11, the print control unit 13 moves the line sensor 14 to the horizontal line detection device, and the print head 16 and the motor 1
6, the printer moves on the paper, detects a horizontal line, and then starts printing. A clutch or the like is used to move between the vertical trace line detection position and the horizontal trace line detection position by the sensor 14. Moreover, the crevice sensor 14 has a set of a light emitting part and a light receiving part,
When a trace line is detected, the electrical signal changes. Additionally, it can be used as a general printing device without using the vertical/horizontal line detection command. Also, host computer 1
A horizontal line can be detected at any position by the print head movement command from 1.

Furthermore, by adding the amount of movement of the paper and the head to the vertical/horizontal line command, it becomes possible to print at a fixed location from the groove line.

Effects of the Invention As is clear from the above embodiments, the present invention is equipped with a sensor that detects pre-printed lines, so when it is necessary to print on a format-printed paper with a frame, printing using a word processor or the like is possible. 0 that can shorten data creation and print within the paper frame.
