Abstract

PURPOSE:To enhance a printing processing speed by continuously performing the format feed operation of the previous page and the feed operation up to the first line printing position of the next page, by reversely feeding continuous printing paper to detect the leading end thereof by a paper leading end detection sensor and calculating the distance between the leading end of the continuous printing paper and a cutter. CONSTITUTION:Printing paper 5 is mounted on a platen 2 to match the first line printing position 5a of said paper 5 with the position corresponding to a printing head 4. After this setting operation is finished, the printing paper 5 is once reversely fed to be operated until the leading end 5b of the printing paper 5 reaches a paper leading end detection sensor 1, and reverse feed quantity is preliminarily stored in the memory device in a printer. In this case, since the distance from the position of the paper leading end detection sensor 1 to the cutting position of a cutter 3 is known, the distance S up to the position of the cutter 3 can be known from the position of the leading end 5b of the printing paper 5 when the first line printing position 5a is present at a printing position. Therefore, at the time of format feed operation, the printing paper 5 can be continuously sent to the first line printing position of the next page.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device equipped with a cutting machine next to which continuous paper is mounted and equipped with a cutter for cutting the continuous paper.

[Conventional technology]

Conventional printing devices that use continuous paper and are equipped with a cutter mechanism that cuts it are able to control the position of the leading edge of each member of the printing paper and the cutting (
The printing paper is fed out at the time of cutting by a length corresponding to the difference from the cutting position, and perforations, which are provided to distinguish each member of the paper and facilitate separation, are aligned with the cutting position.

In this way, with conventional printing devices attached to the side of the cutter, the printing device only knows the relationship between the cutting position and the position of the leading edge of each member of the printing paper, so the position of the leading edge of each member is determined by the higher-level device. It is necessary to issue a line feed command from to the first line printing position. In this case, the form feed operation of the previous page (the operation of feeding the paper from the line where printing ends for each member to the end of the page) and the feed operation from the leading edge of the next page to the first line printing position are continuous. Instead, the form feed operation for the previous page is completed, and then the new page operation for the next page is performed.

[Problem that the invention seeks to solve]

As mentioned above, in conventional printing devices that use continuous paper, the form feed operation for the previous page and the feed operation for the next page are separated and do not operate continuously, so the processing time per page is long. However, there is a drawback that the printing processing speed of the printing device is reduced.

An object of the present invention is to eliminate the drawbacks of the conventional printing device as described above, and to enable the form feed operation of the previous page and the feed operation of the next page to be performed continuously, thereby increasing the printing processing speed. An object of the present invention is to provide a printing device that can be improved.

[Means for solving problems]

The printing device of the present invention is equipped with a paper leading edge detection sensor that detects the distance between the cutting position of the paper and the leading edge position of the paper when the printing paper is at the first line printing position, when the printing paper is set, and the printing device is equipped with a paper leading edge detection sensor that detects the distance between the cutting position of the paper and the leading edge position of the paper when the printing paper is at the first line printing position. When it is first installed, the printing paper is moved down and the paper leading edge detection sensor detects the leading edge position of the printing paper. From this, the distance from the first line printing position to the leading edge position of the paper is calculated, and the When performing a page form feed operation, the feed operation (feed operation) is continuously performed by the calculated distance.

That is, the printing device of the present invention includes a cutter disposed above the print head and a paper leading edge detection sensor disposed below the print head, and is capable of mounting continuous printing paper. After adjusting the printing position of the first line of the first page to a position corresponding to the print head, the continuous printing paper is reversely fed and its leading edge is detected by the paper leading edge detection sensor, thereby performing the continuous printing. The method includes calculating the distance between the leading edge of the paper and the cutter, and adding the calculated distance during the form feeding operation of the continuous printing paper to continuously perform the feeding operation.

〔Example〕

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

FIG. 1 is a side view showing the configuration of an embodiment of the present invention.

In FIG. 1, reference numeral 1 indicates a paper leading edge detection sensor;
The platen 2.3 is a cutter, and 4 is a print head.Their positional relationship is that the cutter 3 is above the print head 4 (in the direction in which the print paper is fed), and the paper leading edge detection sensor 1 is below the print head. (in the direction in which the printing paper is moved down).

FIG. 2 is a side view showing the embodiment shown in FIG. 1 with printing paper attached.

In FIG. 2, the printing paper 5 is mounted on the platen 2, and the -th row printing position '15a is aligned with the position corresponding to the printing head 4. After setting the printing paper, press a switch on the operation panel (not shown) to move the printing paper 5 forward (reverse feed) until the leading edge 5b of the printing paper reaches the paper leading edge detection sensor 1. make it work. The amount of downward movement (reverse feed amount) at this time is stored in the storage device within the printing device.The difference between this reverse feed amount and the known distance from the position of the paper leading edge detection sensor 1 to the cutting position of the cutter 3 , the distance from the position of the paper leading edge 5b to the position of the cutter 3 when the first row printing position 5a is set to the position corresponding to the print head 4 is 1lIiS.

Therefore, since it is possible to know the distance S from the position of the paper leading edge 5b to the position of the cutter 3 when the first line printing position 5a is at the printing position, it is possible to know the distance S from the position of the paper leading edge 5b to the position of the cutter 3. Print paper 5 can be fed continuously. When cutting the paper, first line printing position 5a
By feeding out the printing paper 5 by a distance S, the perforation of the printing paper can be aligned with the position of the cutter 3.

〔Effect of the invention〕

As explained in detail above, by using the printing device of the present invention, the format feeding operation of the previous page and the feeding operation to the first line printing position of the next page can be performed as a continuous operation, so that printing This has the effect of improving processing speed.

Claims (1)

[Claims] A cutter is provided above the print head, and a paper leading edge detection sensor is provided below the print head. After adjusting the line printing position to a position corresponding to the print head, the distance between the leading edge of the continuous printing paper and the cutter is determined by reversely feeding the continuous printing paper and detecting its leading edge by the paper leading edge detection sensor. , and adding the calculated distance when performing a form feeding operation of the continuous printing paper to continuously perform the feeding operation.
