Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus mainly used for issuing documents such as bills and checks in financial institutions and companies, and the characters and symbols required for a continuous form sheet. The present invention relates to a form printing device that prints.

[0002]

2. Description of the Related Art Conventionally, the work of filling out so-called requirements such as customer name and issuing store name on forms such as bills and checks is done by hand, or a printing device using a general-purpose printer for office machines is used. It was being appreciated.

As shown in FIGS. 3 and 4, the structure of the conventional general-purpose printer for office equipment is such that printing is performed by the positional relationship between the print head 1 that moves in the horizontal direction and the paper P that moves in the vertical direction in the printer. Has been done.

That is, FIG. 3 shows an example using the mechanism of a conventional general-purpose printer for office machines.
A print head 1 is movably provided along a head lateral feed guide 2, and the print head 1 is laterally fed by a belt 3a rotated by a head lateral feed motor 3. On the other hand, the sheet P is sandwiched between the sheet vertical feed rollers 4 and 4a, and the sheet vertical feed motor 5 or the like rotates the sheet vertical feed roller 4 forward or backward to raise or lower the sheet P. A paper track mechanism (not shown) for carrying in the paper in the lateral direction and carrying out the paper in the lateral direction is provided on the paper carry-in side and the carry-out side of the printer.

The relationship between the movement of the paper P and the printing operation in the conventional apparatus will be described with reference to FIG.
(B) Next, the paper P is raised by the paper vertical feed roller 4 and the print head 1 is moved laterally along the horizontal head feed guide 2 so that the print coordinates on the paper surface are two-dimensionally. While printing is performed at that position while selecting, (c) the paper vertical feed roller 4 is reversed to lower the paper P, and the paper is returned to the height at which it was loaded. Carry out.

[0006]

In the printing apparatus using the mechanism of the general-purpose printer for office equipment described above, the structure is such that the paper P is moved in the vertical direction for printing, so that a wasteful time is generated in the working time. Cheap. In other words, because the structure is such that the direction of movement of a sheet that has been conveyed in from the side by the sheet conveyance path is changed to the vertical direction, the sheet is said to be conveyed in lateral movement, raised in longitudinal movement, lowered in longitudinal movement, and ejected in lateral movement. You will follow the process. The ascending movement of the paper here is an operation necessary for printing, but the paper descending operation is simply a work of returning to the position for carrying out, and the paper descending time is a wasteful time, and the print processing capability is Will be lowered.

If an attempt is made to reduce the working time in the mechanism of the conventional general-purpose printer as described above, there arises a problem that the sheet conveying path becomes complicated. That is, in order to eliminate the paper descent time, the paper carry-out path must be provided above the paper carry-in path.

The present invention has been made in view of the above circumstances, and provides a printer having a structure in which a wasteful time associated with the movement of a sheet is minimized and a sheet conveyance path does not require a complicated path. It is intended to be provided.

SUMMARY OF THE INVENTION The present invention is a form printer for printing predetermined requirements on a form paper such as a bill or a check by a print head, and stops the paper at a predetermined position in the middle of the paper conveyance path. The form printing apparatus includes a paper positioning mechanism for positioning the print head, and a head moving mechanism for moving the print head vertically and horizontally at any coordinate position on the positioned paper surface.

[0010]

According to the present invention, after the paper is positioned in the middle of the paper transport path, only the print head is moved in the vertical direction and the horizontal direction without moving the paper, and the predetermined requirements are printed at the predetermined writing position on the paper. To do.
