BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to printers.

0002

2. Description of the Related Art Conventional printers have a paper feed function as shown in FIG. The operation will be explained according to FIG. 2. An operator sets unprinted paper 3 on the paper tray 12 into the push tractor feeder 4 at the rear of the printer 13. By pressing the switch on the operation panel 6 at the front of the printer, paper is transferred to the push tractor feeder 4.
The paper is fed in the front direction of the printer by the drive of the paper, passes between the print head 7 and the platen 14, and stops when the leading edge of the paper reaches the position of the cutter 9. Thereafter, printing is started in response to a command from the host device, and the printed paper 10 is further fed by the drive of the push tractor feeder 4, passes over the sheet guide 15 at the top of the printer, and returns to the paper tray 12. After printing is completed, the operator cuts the paper at the cutter 9 position and presses the switch on the operation panel 6 again, so that the leading edge of the paper is rolled up by the reverse rotation of the push tractor feeder 4 and stops at the position of the push tractor feeder 4.

[Problems to be Solved by the Invention] The conventional printers described above have problems such as the push tractor feeder being located at the rear of the device, making it difficult to set paper, the paper curving over the platen, which tends to cause jams, and the print head and platen not working properly. There are problems such as the installation space required for the push tractor feeder because it is located on a substantially flat surface.

[0004] An object of the present invention is to make it easy to set paper;
The objective is to provide a printer with a small installation area that is less likely to jam.

[0005]

[Means for Solving the Problems] The printer of the present invention uses a push tractor feeder to move paper and print. A printed paper holder is provided at the bottom for placing the printed paper.

[0006] In the printer of the present invention, the push tractor feeder and the print head may be arranged in series in the vertical direction.

The printer of the present invention may be provided with a flat platen.

[0008]

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional side view of one embodiment of the present invention.

The printer main body 1 has an unprinted paper tray 2 at the top, a push tractor feeder 4 at the upper part of the interior, and
A print head 7 and a flat platen 8 are provided below the push tractor feeder 4. The printer main body 1 also includes a cover 5 on the front surface for use when setting unprinted paper 3, an operation panel 6 on the top surface, a printed paper tray 11 on the bottom for placing printed paper 10, and a print head. A cutter 9 is provided at the bottom of the cutter 7.

Next, the operation will be explained.

The operator takes the unprinted paper 3 on the unprinted paper tray 2 located at the top of the printer main body 1 into the inside of the printer main body 1 through the slit on the top surface of the printer main body 1, and holds it diagonally with respect to the horizontal plane. Set it on the push tractor feeder 4 installed at about 45 degrees. At this time, the operator opens the front cover 5 of the printer 1 forward and sets the unprinted paper 3 into the push tractor feeder 4 from the front of the printer 1. After setting the unprinted paper 3 and before starting printing, the operator presses the paper feed switch on the operation panel 6 located on the top surface of the printer main body 1, so that the unprinted paper 3 is fed to the push tractor feeder 4. The sheet 3 is fed downward, passes between the print head 7 and the horizontal platen 8, and stops when the leading edge of the unprinted sheet 3 reaches the cutter 9. Thereafter, printing is started in response to a command from the host device, and feeding by the push tractor feeder 4 and printing by the print head 7 are repeated. Since the printed paper 10 is fed downward, characters are printed in the paper feeding direction. The printed sheets 10 are stacked on a printed sheet holder 11. After printing is completed, the operator places the printed paper 1 at the cutter 9 position.
Cut out 0. After that, if you want to use another paper, press the paper feed switch on the operation panel 6 again to feed the paper in the opposite direction, and the leading edge of the unprinted paper 3 will be retracted to the position of the push tractor feeder 4. , the unprinted paper 3 can be easily removed.

[0013]

[Effects of the Invention] As explained above, in the present invention, the push tractor feeder is placed above the print head so that paper can be set from the front of the printer, thereby making it easier to set paper and reducing the curvature of the paper path. By reducing the number of paper jams, paper jams are less likely to occur, and since the push tractor feeder, platen, and print head are arranged perpendicularly to the installation surface, the installation area can be reduced.
