Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a printing device capable of printing on a single sheet of paper or a multi-sheet sheet of paper (hereinafter referred to as a sheet) in an output device of an electronic computer. It is related to.

A conventional printing device is equipped with a line feed conveyance roller on one side of the print head, and this roller conveys the ticket under the print head in a line feed manner. Such printing devices include:
There is one disclosed in Japanese Unexamined Patent Publication No. 140111/1983.

However, with such devices, it is not possible to carry out a line feed operation over the entire sheet, and printing over a wide area of the sheet is not possible. As time goes on, when the trailing edge of the cut sheet comes off the roller, it becomes impossible to carry out line feed conveyance of the cut sheet below the print head any further. There are mechanical restrictions between the print head and the rollers, and this distance cannot be eliminated. In this manner, in the conventional printing apparatus, printing is not performed on the cut sheet in a portion corresponding to this distance.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printing device that allows a changeover operation to be performed over the entire surface of a ticket.

An embodiment of the present invention will be described in detail below with reference to the drawings.

The printing device of the embodiment shown in the figure is capable of printing on both single sheets and continuous sheets.

As shown in the figure, the continuous paper 1 used in this printing apparatus is placed at the rear of the printing apparatus so that it can be set into the printing apparatus from the rear. on the other hand.

By setting the ticket 2 on the table 3 in front of the printer, the ticket 2 can be automatically retracted as described below.

In the initial state, the first ticket conveyance follower collage 8 is lifted in the direction of the arrow 9, and a gap is provided between it and the first ticket parking roller 13 for the ticket 2 to enter. . In this state, the cut conveyance guide surface 12 of the table 3
The operator places the cut 2 on the board and sets the left end of the cut 2 on the cut left edge guide 4 and the tip of the cut 2 lightly against the cut edge guide 5, thereby detecting the left edge detection element of the cut. 6 and the cut edge detection element 7 detect the presence of the cut cut 2.

When the cut left end detection element 6 and the cut tip detection element 7 detect the presence of the cut 2, the cut leading edge guide 5 moves in the direction of the arrow 11 under the control of the control unit 10, and the cut cut leading edge guide 5 moves in the direction of the arrow 11. It's becoming more engaging. In addition, when the cut leading edge guide 5 is pulled in from the cut transport guide surface 12, the first cut transport follower roller 8 moves in the opposite direction of the arrow 9 in mechanically interlocked with this, and the cut 2 is moved into the first cut transport guide surface 12. 1 Press it against the moving roller 13.

Next, under the control of the control unit 10, the cut drive motor 14 is driven to rotate the second cut drive roller 13 and the second cut drive roller 20 (note that the cut 2 is currently in the second cut drive roller 20). Since the sheet has not reached the sheet beating roller 20, the second sheet driving roller 2o does not actually convey the sheet.
), as a result, the ticket 2 is conveyed in the direction of arrow 15 along the almost straight conveyance path. The conveyance amount of the cut sheet 2 in the direction of the arrow 15 is controlled by the control section 10, and the cut sheet drive motor 14 is stopped when the cut sheet has been conveyed by a predetermined conveyance amount. As a result, the first row of the ticket 2 is conveyed and set below the print head 16.

After setting the first line of cut sheet 2, carrier motor 17
The print head 16 is moved by the carrier 18
is moved in the column direction, and predetermined printing is performed via the ink ribbon 19.

After driving the ticket movement motor 14 and changing the line of the quantitative ticket 2, the above-mentioned carrier 18. By the operation of the print head 16, predetermined printing is performed on the second line.

Thereafter, printing of the third and subsequent lines is performed in the same manner as the printing of the first and second lines.

When the line feed is further performed and the ticket 2 is sent in the direction of the arrow 15, the leading end of the ticket 2 reaches the second ticket drive roller 20. Second
The parking force of the cut drive roller 20 is the same as that of the first cut drive roller 13.
Similarly, it is applied from the ticket drive motor 14. Therefore, as soon as the tip of the cut 2 reaches the second cut beating roller 20, the cut 2 is immediately subjected to a conveying force by the second cut drive roller 20. Hereinafter, the first and second cut drive rollers 1
3.20, ticket 2 is conveyed on a new line.

After the rear end of the ticket 2 comes off the first ticket drive roller, the ticket 2 is conveyed line-by-line only by the second ticket drive roller 20.

In this way, this printing apparatus has two pairs of the cut follower roller 8 and the first cut slipping roller 13, and the second cut follower roller 21 and the second cut drive roller 20, in front and behind the printing position. , the cut sheets 2 are conveyed line by line by intermittent feeding operation in conjunction with the cut sheets 2.

As a result, it becomes possible to carry out the reversing operation over the front side of the ticket 2, and the printing range of the ticket 2 is expanded.

The printed ticket is normally conveyed in the direction of the arrow 22 and returned to the table 3 by rotating the ticket drive motor 14 in the opposite direction to the printing line feed direction. If the operator wishes to discharge the printed sheets to the stacker 23 provided at the rear of the printing device.

By operating the operator panel 24, the single sliding roller 2
0 and further conveying in the direction of arrow 28,
It is also possible to discharge the ticket 2 to the stacker 23.

The continuous paper 1 is guided to the same printing position as the single sheet, and printing on the continuous paper 1 is performed by rotating a tractor 26 by a continuous paper parking motor 25 controlled by the control unit 10 so as to perform the desired line feed. It has become.

The operations of the carrier 18 and print head 16 are the same as when printing on the cut sheet 2.

As shown in the figure, the printing position of the cut sheet 2 and the printing position of the continuous paper 1 are the same platen 27, so that printing can be performed only on the cut sheet 2 and only on the continuous paper 1.

Furthermore, it is also possible to simultaneously copy the contents printed on the cut sheet 2 onto the continuous sheet 1. Specify printing on single sheet 2 or continuous sheet 1, or print sheet 2 on continuous sheet 1.
The designation of overlapping printing can be set by operating the operator panel 24. The control unit 10 operates the single paper drive motor 14 or the continuous paper drive motor 25 according to the set printing designation.
Drive control is performed on one or both motors. In addition, when printing only on the cut sheet 2, by retracting the continuous paper 1 to its supply position, it is possible to avoid the information printed on the cut sheet 2 from being transferred to the continuous paper 1 on the platen 27. is also possible.

In addition, since the drive motors for the single sheet 2 and the continuous paper 1 are independent, the control unit 10 can control the continuous paper 1.
The copying pitch can be varied to a desired amount.

Note that the print head 16 is provided in a substantially vertical direction,
To check the printing status and printed content, use Print Pure 29.
allows the operator to see inside easily.

According to this embodiment, the following effects can be obtained.

(1) By having two pairs of ticket conveyance rollers, line breaks can be made across the front side of the ticket, allowing a wide printing range.

(2) Operability can be improved by eliminating the operator's ticket processing work elements.

(3) By providing a receiving box after ticket processing, it is possible to continuously input tickets, and the operator's work to take out tickets can be eliminated.

(4) Since the cut sheet set is on a horizontal surface, thin paper,
A high degree of printing accuracy can be achieved even on wide and long sheets.

(5) Since the cut conveyance path is straight, it is less likely to cause misalignment in multi-sheet paper, and it is less likely to cause misalignment of the printing position for each piece of paper. Problems such as these are less likely to occur.

(6) Since it is possible to transport a cut sheet with continuous paper set, it is not only possible to print on any paper as needed, but also to copy onto continuous paper at the same time as printing a cut sheet. is also possible. Also.

Since the same single sheet and continuous sheet can be transported with independent line feeds ≠ two, it is possible to greatly improve the creation of copies of information and the management of information.

As is clear from the above description, according to the present invention.

This is because the changeover operation can be performed across the front of the ticket.

Printing 1tiff that allows printing with few margins is obtained.
