Abstract

PURPOSE:To cut a continuous form automatically regardless of the mounting of a cut-sheet feeder by installing a cutter for cutting the continuous form at a position along a horizontal carrying path, cutting the form when printing is completed, changing over a continuous-single changeover means to a cutform mode and discharging the forms. CONSTITUTION:When a continuous form is cut, a carrier 26 is stopped at a position shown in the figure, and the continuous form is forwarded so that a perforation to be cut is brought to a cut location (a). A cutter 2 is intruded to the performation of the continuous form, and the form is cut by movement toward the direction of the printing column of the carrier 26. Cutting at the perforation before carrying-out of the continuous form is conducted by the rotational operation of the cutter 2 and the movement of the carrier. When the continuous form is retreated until it is shunted from a horizontal carrying path 11 and a continuous-single changeover means is changed over to a cutform mode before cut forms are discharged, the continuous form does not prevent discharge to a stacker of the cut forms, thus allowing stable discharge operation.

Description

[Detailed Description of the Invention] [Summary] Regarding a horizontal printer that prints on single sheets and continuous paper, cutting of continuous paper, which was conventionally performed by an operator, can be performed automatically regardless of whether a cut sheet feeder is installed. Moreover, in order to enable the cut sheets and sheets to be discharged, a continuous sheet switching means is provided, and a horizontal sheet for printing each sheet or continuous sheet supplied to a printing unit along the horizontal conveyance path. In the printer, a cutter for cutting continuous paper is provided at a predetermined position along the horizontal conveyance path, and the printer is configured to be able to discharge the print-completed ticket and the continuous paper cut by the cutter after printing is completed.

[Industrial Application Field] The present invention relates to a horizontal printer that prints on single sheets and continuous sheets.

[Prior Art] In this type of conventional printer, when printing on continuous paper is finished, the operator presses a cut mode switch on the operator panel to eject a certain amount of paper, and the paper is transferred to the cutter attached to the cover. I hit it and pulled it off.

[The problem that the invention attempts to solve B1 However, this conventional method had the following various drawbacks.

(1) Paper is difficult to cut (cutting is time consuming)
.

(2) If you select an option such as a cut sheet feeder (hereinafter abbreviated as C3F), cutting will no longer be possible.

The present invention enables continuous paper cutting, which was conventionally performed by an operator, to be performed automatically regardless of whether a C3F is installed or not.
Moreover, it is an object of the present invention to provide a printer capable of ejecting the cut sheets and slips.

In the figure, 1 is a printing section, 2 is a pressure/attached part, and 31 and 3 □ are a stacker for storing ejected paper. be.

Further, 4 is a tractor for conveying continuous paper, 56 is a feed roller, 2, 8 is a pinch roller, and 91.9 □ 10 is a paper guide, which are added for reference.

The printing unit 1 is provided along the horizontal conveyance path 11, and in this figure, an example is shown in which it is composed of a print head 12 and a platen 13 that face each other with the horizontal conveyance path 11 in between.

The cutter 2 is provided at a predetermined position along the horizontal conveyance path 11.

The stacker 31 is provided in front of the horizontal conveyance path 11, and the stacker 3° is provided in the rear of the horizontal conveyance path 11. Incidentally, the stacker 32 is installed and used for processing single sheets.
It is also possible to use the stack section on the 3rd floor.

Note that this figure shows an example in which the tractor 4 and each feed roller 5.6 are driven by a common drive motor 14 via a control unit 15. The connection between the drive morph 14 and the tractor 4 is disconnected when the continuous mode is switched to the single sheet mode.

Further, the stack section does not have to be simply a paper discharge port and cannot store a plurality of sheets. Moreover, the number of discharge ports may be one.

[Effect]

When processing single sheets, there is no need to use cutter 2, and C3
Printing on the slips fed out from F, etc. is performed by the printing unit l, and the paper on which printing has been completed is transferred to the stacker 3. Or it is discharged to stacker 3□. At this time, paper guide 9
0 and 9□ guide the cut sheet, and feed rollers 5 and 6 play the role of conveying the cut sheet.

When processing continuous paper, the continuous paper is transported by the tractor 4, guided by the paper guide 10, and supplied to the horizontal transport path 11. The supplied continuous paper is positioned at a printing start position where the leading edge passes through the printing unit 1 by a predetermined distance, and then printing is performed by the printing unit 1 while feeding the paper to the right with a line feed. After the specified printing is completed, the paper is moved until the cutting position such as the perforation is at the cutter 2 position.
The paper is cut by. Thereafter, the cut sheets are placed in the stacker 3. Alternatively, the paper is ejected to the stacker 3°, but this ejection is performed by switching to the single sheet mode using the continuous paper switching means, and the continuous paper is held by the tractor 4. When discharging to the tractor side, the continuous switching means is in the continuous state, and 1
After sensor 6 detects the edge of the paper, it switches to a single sheet state. Further, a valve 17 is provided at the mouth of the stacker and the tractor, and the continuous sheets are returned to the tractor side, but the cut sheets are discharged to the scroller side. These horizontal transport paths 1

serves to guide the paper, and feed rollers 5 and 6 serve to move the paper.

〔Example〕

The present invention will now be described in detail with reference to FIGS. 2 to 4.

FIG. 2 is a side view showing the main structure of the horizontal printer of this example. In the figure, 21 is a printing section and 22 is a feed roller. Note that the same members as in FIG. 1 are designated by the same reference numerals. In addition, in FIG. 2, the tractor 4. shown in FIG. Drive motor 14. Suftuka 3□Statuka 3□ is omitted.

The printing unit 21 is composed of a print head 12 and a platen 23, and includes a print head 12, a core 1, a guide bar 24.
25 and is mounted on a carrier 26 that is movable in a direction perpendicular to the plane of FIG.

The mounting structure of the cutter 2 is shown in Figure 3 (Figure 3(a) is a plan view,
As shown in FIG. 3(b) is a front view, and FIG. 3(C) is a side view, the cutter 2 is rotatably supported on a support plate 27 that is attached to a carrier 26 with its base as a fulcrum. has been done. This figure shows an example in which one pair of cutters 2 is provided.

Further, a pair of guides 28 are attached to the support plate 27, and a crank-shaped lever 29 is rotatably and slidably supported via a support portion 30. When not cutting, the cutter 2 is biased by a spring or the like and positioned as shown by the solid line in FIG. 3(C), and is retracted from the horizontal +1 feed path 11. The lever 29 rests on this cutter 2''. Paper cutting by the cutter 2 is performed in the following steps.

When cutting continuous paper, the carrier 26 stops at the position shown in FIG. 2, and the continuous paper is fed so that the perforations to be cut are at the cutting position (A) in FIG.

Here, the lever 29 is pressed by a pressing means (not shown) and moves a predetermined amount in the direction of the arrow in FIG. ) and rotate clockwise as shown in Figure 3 (C).
The cutter 2 is positioned at the position indicated by the chain line in FIG. 3(C).

FIG. 4 shows this state, in which the cutter 2 enters the perforation of the continuous paper.

Then, the paper is cut by moving the carrier 26 in the printing digit direction.

Processing operations for single sheets and continuous paper by a horizontal printer having such a main part structure are performed as described above in connection with FIG.
This is performed by the above-described rotational movement of the cutter 2 and movement of the carrier. Note that, before discharging the cut paper, if the continuous paper is moved back until it is evacuated from the horizontal conveyance path 11 and then switched to the single sheet mode, the continuous paper will prevent the cut paper from being discharged to the stacker 3. This enables stable ejection operation.

[Effects of the Invention] As described above, according to the present invention, a cut sheet feeder can perform continuous paper cutting, which was conventionally performed by an operator, and the burden on the operator is reduced. Further, the cut sheets and tickets can be discharged to either the stacker provided at the front or rear LJ.
