Abstract

PURPOSE:To apply printing on a slip at an accurate position even when the width or position of the slip is incorrect by detecting the width and position of the slip by a paper position sensor and editing a printing character row on the basis of the detection result to perform printing. CONSTITUTION:A paper position sensor 1 detects the width and position of a sucked slip and a printing control part 2 generates a printing pattern wherein a printing character row is edited according to the width and position of the slip detected by the paper position sensor 1 and drives a printing head 3. The printing head 3 performs actual printing according to the printing pattern generated by the printing control part 2. When the width and position of a slip 4a are correct, a character is accurately printed on a slip 4b by a printer 10 but, when the width of the slip 4a is small, the width of the slip 4a is detected by the paper position sensor 1 and printing character row is edited to perform printing and, therefore, printing is performed correctly without protruding from a slip 4c.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer, and particularly to a page printer capable of printing on single sheets.

[Conventional technology]

Conventionally, this type of printer has not had a mechanism for automatically editing the stamp printing mechanism according to the width and position of the printing paper.

[Problem to be solved by the invention]

Since it is not possible to edit the conventional printer number, t, and printed character G1 mentioned above, if the width force (correct force) of the cut sheet or the position is shifted (ν), 42G, on the cut sheet. The position of the print will also shift, and if the printing force protrudes from the cut sheet, there will be a defective force.

[Means to solve the problem]

The printer of the present invention has a paper position sensor for detecting the width and position of the ticket, and a print III controller for editing the stamp printing mechanism according to the width and position of the ticket. .

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows the structure of an embodiment of the present invention b).

Paper position sensor 1 detects the width and position of the sucked-in ticket. The print control unit No. 2 generates a printing pattern edited by the paper position sensor 1 (detected width and position of the cut sheet), and drives the print head 3 accordingly.

To print, actual printing is performed according to the print pattern generated by the print prompt control section 2.

2 and 3 illustrate the operation of the printer of the present invention. A printer 10 according to the invention includes a paper position sensor 1 and a print head 3. After being printed by the printer 10, the ticket 4a before inhalation is printed as a ticket 4b (FIG. 2) or 4c (FIG. 3). FIG. 2 shows the printing state when the width and position of the cut sheet 4a are correct, and the characters are correctly printed on the cut sheet 4b. On the other hand, FIG. 3 shows the printing state when the width of the cut sheet 4a is small. Even in this case, the paper position sensor 1 detects the width of the cut sheet 4a and prints by editing the stamp printing mechanism, so that printing is performed correctly without protruding from the top of the cut sheet 4c.

〔Effect of the invention〕

As explained above, the present invention detects the width and position of a cut with a paper position sensor, and edits the stamp printing mechanism based on the detection result to perform printing, thereby adjusting the width or position of the cut. This has the effect that printing can be performed at the correct position on the slip even if it is not correct.

Claims (1)

[Claims] In a page printer equipped with a ticket printing mechanism, there is a paper position sensor that detects the width and position of a ticket when it is sucked in, and a paper position sensor that automatically edits the print character string according to the width and position of the ticket to always print the ticket. 1. A page printer comprising: a print control section for printing at a correct position on the page.
