Abstract

PURPOSE:To enable a printing format to be automatically set through a simple operation, by providing a carriage part with an optical sensor for reading a printing position mark provided on a printing paper and with a controlling circuit for recognizing and storing a printing position based on a signal from the sensor. CONSTITUTION:A controlling circuit for recognizing and storing a printing position based on a signal from an optical sensor 11 comprises a printing position recognition and storage controlling circuit 12, a control panel 13, a format- reading switch 14 and a printer-controlling circuit 15. A printing paper 10 carrying markings 17 according to a format to be used is set to a printer, and an automatic reading switch 14 is depressed, then the printer sequentially reads and stores the positions of markings provided at each prescribed printing position while feeding the paper 10 and performing carriage scanning. Thereafter, printing data partitioned on the basis of each prescribed printing position are transferred from a system to the printer and printing is performed according to the printing format stored in the printer.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a printing apparatus having an automatic formatting function for printing positions on printing paper.

2. Description of the Related Art Conventionally, the paper formatting function of a printing device has been performed using control commands transferred from a system (personal computer, word processor, etc.) to which the printing device is connected.

Problems to be Solved by the Invention With such a conventional configuration, a system statement program must be added or changed each time a new print format is added or changed, which is a problem for general system users. The problem is that it is complicated and difficult.

The present invention solves these problems, and aims to provide a printing device that can automatically set a print format with simple operations.

Means for Resolving the Problem In order to solve this problem, the present invention provides an optical sensor that reads the print position mark on the printing paper in the carriage part of the printing device, and determines the print position based on the signal obtained from the optical sensor. The configuration includes a control circuit that recognizes and stores the information.

How it works With this configuration, a system user can load printing paper with pre-marked print positions into the printing device, perform a format reading operation, and the printing device will recognize the printing format.

It can be memorized.

Embodiment FIG. 1 is a block diagram of a printing apparatus according to an embodiment of the present invention. In FIG. 1, 1 is a print head, and 2 is a print head.
~6 is a carriage mechanism, 2 is a carriage, 3 is a carriage shaft, 4 is a drive belt, 6 is a belt pulley,
6 is a carriage drive motor, and the carriage 2 is scanned in the horizontal direction. 7 to 1o are printing paper transport mechanisms, 7 is a printing platen, 8 is a transmission gear, 9 is a paper drive motor, 1o is a printing paper, and as the printing platen 7 rotates,
Print paper 10 is conveyed in the vertical direction. 11 is an optical sensor, 12 is a print position recognition storage control circuit, 13 is an operation panel, 14 is a format read switch, and 15 is a printing device control circuit.

FIG. 2 is an example of printing paper with markings at printing positions used in one embodiment of the present invention. 1o in Figure 2
is the printing paper, the 160 dotted line is the planned printing position, and 17
is a miking mark painted black with a pencil indicating the left end of the planned printing position.

A user of a system connected to a printing device according to the present invention can:
When the printing paper 1Q that has been marked 1Q according to the format of the printing paper 1Q to be used is set in the printing device and the format reading switch 14 is pressed, the printing device transports the printing paper 10 and performs carriage scanning. At the same time, marking positions for each scheduled printing position are sequentially read and stored. After that, the system transfers the print data separated by each scheduled print position to the printing device, and printing is executed according to the print format stored in the printing device. As described above, according to the present invention, it is possible to designate a printing format by applying the markings 17 on the printing paper 10 and by a simple operation.

Effects of the Invention As described above, the printing device of the present invention can print in a predetermined printing format simply by setting marked printing paper at the printing position, and there is no need to add or change the system program. It has the advantages of being able to create a free printing format without any modification, being easy to use, and being highly practical, and is of great industrial value.
