When the printing operation is completed, the printed portion is cut off by the cutter 8 after the line feed, and the operator 17 obtains one piece of the cut receipt paper for delivery to the customer.

Note that the operation of stamping the stamp 9 on the receipt paper 1 is performed at the start of the printing operation or at the end of the printing operation, but the description of the stamping operation will be omitted here since it is outside the scope of this application.

[Problem that the invention attempts to solve]

However, according to the conventional technology having the above-mentioned configuration, if the operator inadvertently touches the receipt paper in the middle of the paper changing operation due to hurrying to hand it over to the customer after the printing operation, the paper changing operation of the receipt paper will be interrupted. When the print head is moved toward the receipt paper, it gets caught in the sag, causing poor running of the receipt paper, and eventually causing paper jams. It was hot.

In view of the above problems, the present invention provides a printer device that does not cause paper jams even if the operator is prevented from changing the journal paper.

[Means for solving problems]

The present invention is a printer device that prints on two strips of paper with printing areas placed in parallel by moving a single print head by space, and printing on the two strips of paper with a fulcrum as the center. A V-shaped paper holding member having paper guides on the left and right sides for regulating the feeding path of the V-shaped paper holding member is slidable in a see-saw state about the fulcrum, and has its ends facing the two papers. By lowering the paper guide on the side where the print head arrives, the paper guide on the other end is raised, and the paper guide on the side where there is no print head is guided to a fixed position for regulating the paper feeding path. It is characterized by being equipped so that it can be linked with the print head.

[Effect]

With the above configuration, in the present invention, when the print head is performing a printing operation on one of the two sheets of paper, the paper holding guide mounted on the print head moves the paper guide opposite to the sheet on which the printing operation is being performed. descend. As a result, the paper guide at the other end of the V-shaped paper presser moves up around the fulcrum, and positions the paper guide on the side where there is no print head in place.
This paper path can be regulated while the print head is absent.

0, a guide 14 serves as a receiving blade for the cutter 8 and a platen for the stamp 9. Reference numeral 15 denotes a frame-shaped guide having an opening larger than the size of the stamp 9, and the guide 15, together with the guide 14, guides the receipt paper 1 to the receipt outlet 16.

Reference numeral 21 denotes a fixing plate for rotatably supporting the paper presser 18 described above about the rotating shaft 19, and the fixing plate 21 is fixed to a frame 22 of the main body of the printer.

The operation of this embodiment having the above configuration will be explained.

Although not limited to this, in this embodiment for convenience of explanation, the print head 5 prints in the order of receipt paper 1 and journal paper 2, and the printing operation for one line is started from the left margin of receipt paper 1. That's it. Further, the stamp 9 performs a stamping operation on each receipt piece, but since this stamping operation is outside the scope of the present application, a description thereof will be omitted here.

First, the print head 5 performs a printing operation on the receipt paper 1. At this time, as shown in FIG. 1, the print head 5 is located between
Guide so that 8b comes upward. As a result, while the print head 5 is located between Y, the journal paper pressing plate 18b and the journal paper platen 4 regulate the running path of the journal paper 2.

Next, the print head 5, which has completed the printing operation on the receipt paper 1, moves horizontally to the left margin of the journal paper 2 and starts printing on the journal paper 2. At this time, as shown in Figure 1,
The print head 5 is located between Z and the paper holding guide 20
However, the paper presser 18 is guided so that the receipt paper presser plate 18a comes upward as shown by the solid line. As a result, while the printing head 5 is located between Z, the receipt paper pressing plate 18a and the receipt paper platen 3 restrict the traveling path of the receipt paper 1, thereby preventing the occurrence of deflection. Of course, the printing head 5 holds the paper against the platen during printing and regulates the feeding path, so that deflection is always prevented.

As described above, in accordance with the spacing operation of the print head 5, the moving paper presser guide 20 rotates the paper presser foot 18 in a see-saw manner so that the print head 5 always holds the paper on the side on which printing is not performed. .

Thereafter, as in the past, when the print head 5 finishes printing on the journal paper 2, both the receipt paper 1 and the journal paper 2 are moved by the receipt paper platen 3 and the journal paper platen 4, respectively. . At this time, receipt paper 1
is held by the paper presser 18, so even if the operator 17 accidentally touches the receipt paper 1 and applies force, the deflection will only occur outside the receipt outlet 16.

After the changeover operation, print head 5 prints receipt paper 1
Return to the side and start the next printing operation.

When all the printing operations are completed, the printed portion is cut off by the cutter 8 after the line feed, and the operator obtains this cut piece of receipt paper for delivery to the customer.

[Effect of idea]

As explained in detail above, according to the present invention, two
The paper guide facing the printing area of the book's strip-shaped paper is rotated in accordance with the space movement of the print head, and the feeding path of the paper on the side where the print head is not present is always regulated among the two strip-shaped paper. Therefore, even if the operator prevents the paper from changing, no deflection occurs. Therefore, it is possible to obtain a printer device that does not cause running defects even if the operator accidentally touches the paper.

Further, according to the present invention, it is possible to simultaneously eliminate the occurrence of deflection in the printing area due to poor winding of the paper by the paper winding mechanism.
