Abstract

PURPOSE:To exclude the faulty setting of a printing paper due to the simple mistake of an operator by a method wherein a roller driving means is controlled in accordance with the detecting condition of a paper position detecting means to send the printing paper to the optimum position of a printer. CONSTITUTION:A driving control means 16 controls a roller driving means 15 in accordance with the detecting condition of a paper position detecting means 11 to send a printing paper 18 to the optimum position 13 on a printer. In this case, the driving control means 16 drives a roller 14 through the roller driving means 15 based on the informations of the paper position detecting means 11 to move the printing paper 18. When the printing paper 18 is set at a position except the optimum position 13, the paper position detecting means 11 indicates the faulty setting to the driving control means 16. Then, the driving control means 16 reads the indication and drives the roller 14 through the roller driving means 15 to obtain the optimum position 13.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer, and particularly to a printer with a paper position detection device.

[Prior Art] Conventionally, printers used as output devices for computers are
When setting the printing paper, the operator manually sets the printing paper, and in this case, the setting position of the printing paper is also determined manually by the operator.

Therefore, setting the position of printing paper in the printer has been left to the intuition of the operator. In particular, when setting the position of continuous paper, the initial setting position has an important meaning.

[Problems to be Solved by the Invention] In the above-mentioned conventional printers, the setting and positioning of printing paper is left to the manual intuition of the operator. When the printing paper is incorrectly set, the operator often does not notice the mistake, which has the disadvantage that correct printing is not performed.

Particularly in the case of continuous paper, if there is an error in the initial setting position, there is a drawback that printing is repeated one after another with the incorrect setting.

[Means for Solving the Problems] The present invention has been made to solve the above problems, and as a means for solving the problems, a printer with a paper position detection device of the present invention is provided at the top position of each page of printing paper. paper position detection means for optically reading a leading position indication of the print paper to detect whether or not the print paper is at a proper setting position; a roller for feeding the print paper; a roller drive means for rotationally driving the roller; and the paper. The apparatus is configured to include a drive means comprising a drive control means that controls the roller drive means in accordance with the detection state of the position detection means and causes the printing paper to be sent to an appropriate position.

[Example] Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a printer with a paper position detection device according to an embodiment of the present invention.

This printer with a paper position detection device includes a paper position detection means 11 and a drive means 12.

The paper position detection means 11 is configured to optically read the top position of each page of the printing paper 18 to detect whether the printing paper 18 is at a proper set position. A leading position indicator 17 is printed in advance at the leading position of each page of the printing paper 18, and this leading position indicator 17 is optically read by the paper position detecting means 11.

The drive means 12 includes a roller 14 , a roller drive means 15 , and a drive control means 16 .

The roller 14 is rotatably driven to feed the printing paper 18 and perform printing.

The roller driving means 15 is configured to rotate the roller 14.

The drive control means 16 controls the roller drive means 15 according to the detection state by the paper position detection means 11, and moves the printing paper 1
8 to the proper position 13.

Therefore, the drive control means 16 controls the roller 14 via the roller drive means 15 based on the information from the paper position detection means 11.
is driven to move the printing paper 18.

When the printing paper 18 is set, its position is the correct position 1i.
13, the paper position detection means 11 instructs the drive control means 16 to that effect.

The drive control means 16 reads the instruction and drives the roller 14 via the roller drive means 15 to obtain the proper position M13.

[Effects of the Invention] As explained above, the printer with the paper position detection device of the present invention optically reads the leading position display provided at the leading position of each page of the printing paper to determine whether the printing paper is at the proper setting position. a roller for feeding the printing paper; a roller driving unit for rotationally driving the roller; Since the configuration includes a drive means consisting of a drive control means for feeding the paper to the proper position, it is possible to eliminate incorrect setting of printing paper due to a simple mistake by the operator, and as a result, the printer's resources (
This has the effect that paper, time, etc.) can be used more effectively.
