Abstract

PURPOSE:To perform printing while avoiding the rule or frame line applied to paper by providing a line detection sensor detecting the line applied to the paper before printing and a control circuit determining the printing position of the paper on the basis of the output of the line detection sensor. CONSTITUTION:When printing is performed, a line detection sensor 5 detects a rule or a frame line to send a signal (a) to a printing position control circuit 4 as line detection data. The printing position control circuit 4 receives the signal (a) to operate a printing position and sends a signal (c) to a central control circuit 3 as printing position data being the operation result. The central control circuit 3 receives a signal (b) as the paper sensing data from a paper detection sensor 2 and sends the signal (a) to a printing circuit 1 as printing data while monitors the signals (b), (c). The printing circuit 1 performs printing on the basis of the received printing data. By this method, printing can be performed so as not to be superposed on the rule or frame line on paper.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to an iJ printer device, particularly in a printer device having a sensor for detecting paper, etc., printing for determining the printing position on paper having ruled lines or frames. Place the pieces in the positioning method.

(Prior Art) Conventionally, the printing position determination method of this neck printer device was as follows:
A sensor detects whether the paper has an axis at the printing location and the leading position of the paper, and the printing position is determined based on this.

FIG. 2 shows a block diagram of such a conventional example.

In FIG. 2, a paper detection sensor 2 detects the presence or absence of paper and sends a signal as vapor sense data to a central control circuit 3.
send to The central control circuit 3 sends a signal a as print data to the print circuit 1 while monitoring the presence or absence of paper. Print circuit 1
receives signal a and performs printing.

(Problem to be Solved by the Invention) The printing position determining force formula of the printer device from the FCF mentioned above is as follows.
The printer only detects the presence or absence of paper and its leading position, and sets the printing position regardless of the ruled lines or frames that are preprinted on the paper, so characters may be printed overlapping the ruled lines or frame legs. There is a drawback.

The purpose of the present invention is to eliminate such drawbacks and improve paper quality.]
To provide a printing position tlig constant force type for a printer device that can print while avoiding ruled lines and frame lines.

(Means for Solving the Problem) In order to achieve the obviousness of erasure, the printer of the present invention uses a line detection method that detects the lines attached to the paper before printing. The sensor 5 is configured to command a control circuit that determines the position to be printed on the front Re paper based on the output of at least the line detection sensor ''+75.

(Example) Next, an example of the present invention will be described with reference to Japan.

FIG. 1 Qi is a small block diagram of an embodiment of the present invention.

As in the first section 1/J list, this embodiment has the same printing times M 1% paper detection sense 2, center 11 fli
8 In addition to the circuit 3, the output of the line detection sensor 5 and the line detection sensor 5, which detects the ruled lines and frames preprinted on the paper (hereinafter referred to as line detection sensor), is input to determine the printing position. The fljll m1 circuit (print position control circuit) 4 that regulates the movement is provided.

Furthermore, the paper detection sensor 2 and the ice detection sensor 5 may be used as a 1Rj-sensor.

When printing is equalized in such a configuration (0), the gauze output sensor 5 detects ruled lines and frame lines, and inputs the transmission @a to the print position control circuit 4 as line detection data. Printable level
#Circuit 4 receives signal a and calculates print color tl≧1−;
The result is sent as printing position r1 data to the central control circuit 3 as the can number C. The central control circuit 30 receives vapor sense data from the paper detection sensor 2, and sends the fiber a to the print circuit 1 as print data by monitoring the signal C and the signal C. The printing circuit 1 performs printing based on the received print data. In this way, it is possible to print so as to overlap the ruled lines and frame line 1 on the paper.

(Effects of the Invention) As explained above, the present invention detects the ruled lines and frame lines of paper using a sensor and determines the printing position based on the output, thereby automatically setting the position that does not overlap with the ruled lines and frame lines of the paper. This has the advantage of being able to be set.

Therefore, if this embodiment is used, even if the paper has ruled lines or frame lines, printing will not be performed on them.
