Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an output device for an electronic computer.
The present invention relates to 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).

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. As such a printing device, there is one shown in Japanese Patent Laid-Open No. 53-140111.

However, with such a device, it is not possible to carry out the reversing operation over the entire surface of the ticket, and printing over a wide range of the ticket is not possible. In other words, when feeding a ticket to the print head using a roller, when the trailing edge of the ticket comes off the roller as the line feed is carried out,
It is no longer possible to carry out line feed conveyance of the cut sheet below the printing head. There are mechanical constraints 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 paper feed change operation to be performed over the entire surface of a ticket.

Hereinafter, one embodiment of the present invention will be described in detail based on 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 cut conveyance follower roller 8 is lifted in the direction of the arrow 9, and a gap is provided between it and the first cut drive roller 13 for the cut 2 to enter. In this state, the operator places the cut 2 on the cut conveyance guide surface 12 of the table 3, and places the left end of the cut 2 on the cut left end guide 4.
By setting the leading edge of the cut 2 in a position where it is lightly pressed against the cut leading edge guide 5, the left edge detection element 6 and the leading edge detection element 7 detect the presence of the 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 tip guide 5 is pulled in from the cut conveyance guide surface 12, the first cut conveyance follower roller 8 moves in the opposite direction of the arrow 9, mechanically interlocking with this, and the first cut sheet conveyance follower roller 8 moves in the direction opposite to the arrow 9. Press it against the ticket drive roller 13.

Next, under the control of the control unit 10, the ticket drive motor 14 is driven, and the second ticket drive roller 13 is driven.
and rotates the second cut-sheet driving roller 20 (note that the cut-sheet 2 has not reached the second cut-sheet driving roller 20 at this point, so the second cut-sheet driving roller 20 does not actually carry out conveyance). ). As a result, the cut sheet 2 follows the conveyance path on an almost straight line as indicated by the arrow 15.
conveyed in the direction. 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, single ticket 2
The first line is conveyed and set below the print head 16. After setting the first line of the cut sheet 2, the print head 16 is moved in the column direction by a carrier 18 driven by a carrier motor 17, and predetermined printing is performed via an ink ribbon 19.

After driving the ticket drive motor 14 to feed the quantitative ticket 2, the carrier 18 and print head 16 described above
By this operation, predetermined printing is performed on the second line. Below, the printing from the 3rd line onwards will also be printed on the 1st line and the 2nd line.
This is done in the same way as printing the row.

When the line feed is further performed and the cut 2 is sent in the direction of the arrow 15, the leading edge of the cut 2 reaches the second cut drive roller 20. The driving force for the second cut drive roller 20 is applied from the cut drive motor 14, similar to the first cut drive roller 13. Therefore, as soon as the tip of the cut 2 reaches the second cut drive roller 20, the cut 2 receives a conveying force from the second cut drive roller 20. Thereafter, the ticket 2 is conveyed by the first and second ticket drive rollers 13 and 20 in 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 a cut follower roller 8 and a first cut drive roller 13 before and after the printing position.
Furthermore, it has two pairs of a second cut follower roller 21 and a second cut drive roller 20, which interlock the cut 2 and transport the cut 2 line-by-line by intermittent feeding operation.
As a result, the reversing operation can be performed over the entire surface 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, the sheet drive roller 20 can be further driven to convey in the direction of the arrow 28 by operating the operator panel 24. 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 drive motor 25 controlled by the control unit 10 so as to perform a desired line feed. It's summery.

The operation of the carrier 18 and print head 16 is as per sheet 2.
This is the same as when printing to .

As shown in the figure, the printing position of the single sheet 2 and the printing position of the continuous paper 1 are the same platen 27, so that printing only on the single sheet 2, printing only on the continuous paper 1, and even printing on the single sheet 2 are possible. Continuous paper 1
It is also possible to make copies simultaneously. The designation of printing on the cut sheet 2 or the continuous paper 1, or the designation of printing on the continuous paper 1 with the cut sheet 2 can be set by operating the operator panel 24. The control unit 10 controls the drive of either the cut sheet drive motor 14 or the continuous paper drive motor 25, or both motors, according to the set printing designation. Note that when printing only on the cut sheet 2, by retracting the continuous paper 1 to its supply position, the information printed on the cut sheet 2 on the platen 27 will be transferred to the continuous paper 1.
It is also possible to avoid being transferred to

Furthermore, since the drive motors for the single sheet 2 and the continuous paper 1 are independent, the control section 10 can control the pitch of copying onto the continuous paper 1 to a desired amount.

The printing head 16 is arranged in a substantially vertical direction, and the operator can easily check the printing status and printed contents through the print viewer 29.

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

(1) By having two pairs of ticket conveyance rollers,
Line breaks can be added across the entire sheet, allowing for a larger print area.

(2) Operability can be improved by removing 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 sheet set is on a horizontal plane, a high degree of printing accuracy can be achieved even on thin paper, wide sheets, and long sheets.

(5) Since the cut sheet conveyance path is straight, it is difficult for multi-sheet paper to be misaligned, and the printing position of each piece of paper is less likely to be misaligned. Also, since the cut conveyance path is straight, troubles such as jamming 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.
In addition, since single sheets and continuous sheets can be conveyed with independent line feed pitches, 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, a printing device capable of printing with small margins can be obtained because the reversing operation can be performed over the entire surface of the ticket.
