Abstract

PURPOSE:To omit the alignment of a sheet, the work of setting a length in case of outputting by a printer by providing holes indicating the position of a sewing line to be detected by an optical sensor mounted in the printer at a left or right side end separately from feeding holes. CONSTITUTION:Feeding holes 3A, 3B of a tractor are continuously formed at an equal interval at a pair of right and left holes at both ends of a printer sheet 1, and holes 2, 2 indicating a sewing line 4 are formed between the holes 3A. When the sheet 1 is fed, the holes 3A, 3B are detected by optical sensors 20A, 20B of a printer, and the fact that the feeding of the sheet 1 at a predetermined length is confirmed. Since the holes 2 indicating the line 4 is provided only at the right side end, the sensor 20B attached to the other left side end does not detect any when the hole 2 passes the sensor 20A attached to the right side end of the printer. Thus, when the right and left sensors sense differently, the fact that the line 4 of the sheet 1 arrives at a predetermined position can be known.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to printer paper, and more particularly to printer paper for continuous forms provided with holes for feeding by a printer's tractor.

[Prior art 1] Conventional printer paper for continuous forms is provided with perforations at fixed intervals in the horizontal direction so that it can be cut into pieces of a fixed length, and also has perforations for feeding the paper in the printer. Automatic tractor feed holes were arranged at equal intervals in the vertical direction on the left and right ends.

[Problems to be Solved by the Invention] The conventional printer paper for continuous forms described above does not have a mark to indicate the perforation position, so when using this paper, it is necessary to It was necessary to align it with a predetermined position that served as a landmark on the printer. In addition, the length of this paper, that is, the length of the paper in the vertical direction from one perforation to the next, is set in advance for the output device to ensure that the paper is fed page by page. It was a pain and had to be done.

[Means for Solving the Problems] The present invention has been made in order to eliminate the drawbacks of the conventional continuous paper described above, and in order to achieve this problem, the printer paper according to the present invention has a In printer paper for continuous forms, which has a series of holes for feeding by the printer's tractor and perforations for separating the paper at regular intervals, separate from the feed holes, the left end or right end A hole is provided in the printer to indicate the position of the perforation, which is detected by an optical sensor installed in the printer.

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

FIG. 1 is a perspective view schematically showing an embodiment of the present invention.

In the drawing, a pair of holes 3A and 3B for feed by a tractor are arranged at equal intervals on both ends of the printer paper 1, and these holes 3A and 3B are connected to the protrusion 5 of the printer's tractor IO. Since the printer paper 1 is latched, the printer paper 1 is fed by the rotation of the tractor 10. However, between the holes 3A connected to the right end of the paper, there are holes 2 for indicating perforations 4,
2 is provided. When this printer paper l is fed, the printer's optical sensors 2OA and 20B
As a result, these holes 3A and 3B are detected, and it is confirmed that a certain length of paper l has been fed. However, since the hole 2 for indicating the perforation 4 is provided only on the right edge, when this hole 2 passes the sensor 2OA attached to the right edge of the printer, the sensor attached to the other left edge 2OB detects nothing. In this way, when the left and right sensors sense differently, the printer can know that the perforation 4 of the printer paper l has reached the predetermined position. Therefore, if the printer continues feeding until it detects the hole 2 for indicating the perforation 4, and then stops the feed when it detects this, the printer can automatically set the paper l in the predetermined position. can. On the other hand, the printer detects the length of the printer paper l by detecting the interval between the holes 2 for indicating the perforations 4 of the print paper l, and automatically sets the paper length. It becomes possible to do so.

[Effects of the Invention] As explained above, the present invention provides a printer for continuous forms, which has feed holes for the printer's tractor at the left and right ends, and perforations for separating sheets at regular intervals. In the paper, separately from the feed hole,
A hole is provided on the left or right edge to indicate the perforation position, which is detected by an optical sensor installed in the printer, so the printer can automatically align the paper position and automatically set the printer paper length. This has the effect of omitting the work of aligning the paper and setting the length when outputting with a printer.

Claims (1)

[Claims] In printer paper for continuous forms, which has holes for feeding by the printer's tractor on the left and right edges, and perforations for separating the paper at regular intervals, there is a hole on the left edge that is separate from the feed holes. Alternatively, a printer paper characterized in that a hole is provided at the right end to indicate a perforation position that is detected by an optical sensor installed in the printer.
