Abstract

PURPOSE:To automatically feed out cutform sheet by sheet to be printed and store the printed cutform in a cutform storing portion by feeding out cutform by a platen and a pressure roller. CONSTITUTION:When cutform 2 is inserted between a platen 6 and a pressure roller 4, the platen 6 is controlled to rotate clockwise. The cutform 2 is sent to a printing position. When the platen 6 is rotated clockwise, an idle gear 10 is moved in the direction of separating from a roller gear 11 centering round a shaft of the platen 6 not to transmit the rotation of the platen 6 to a paper feed roller 3. Accordingly, the next cutform 2 is not fed out. When the platen 6 rotates clockwise, the cutform 2 is advanced to a printing position by the platen 6 and the pressure roller 4 to conduct the printing operation. After the completion of printing operation, the cutform is stored in a cutform storing portion provided in the rear portion of a printer apparatus by the platen 6 and a pressure roller 5. The above operation is repeated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device for printing on slip paper.

[Conventional technology]

Conventional printers that attach cut sheets and print on them do not have a paper feeding mechanism and a paper storage section in the main body of the printer for automatically and continuously feeding the cut sheets. Generally, a sheet feeder or cassette cartridge separate from the main body of the printer is installed and used.

[Problem to be solved by the invention]

The above-described conventional paper feeding and paper storage methods of printer devices have a drawback in that the printer device alone cannot automatically and continuously feed the sheets.

[Means to solve the problem]

The printer device of the present invention includes a platen gear attached to an end face of a platen, a planetary arm rotatably attached to the shaft of the platen, and an idle gear rotatably attached to the tip of the planetary arm and meshing with the platen gear. , the cut sheet loading section provided in front of the platen, and the cut sheet stored in the cut sheet loading section! ! a movable part to be placed;
a spring that applies an upward pressing force to the movable part; a paper feed roller that contacts the topmost paper of the cut sheets placed on the movable part; and a spring that is attached to an end of the shaft of the paper feed roller. a roller gear that meshes with the idle gear when the platen rotates counterclockwise; and two roller gears that are provided on the left and right sides above the platen and that sandwich the cut sheet between them and feed the sheet. The press roller includes a pressure roller, and a cut paper storage section that stores the cut paper sent out by the platen and the pressure roller.

〔Example〕 Next, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a side view showing one embodiment of the present invention, Fig. 2(a)
and (b) are side views showing the main parts of the embodiment in FIG. 1 in different operating states.

In FIGS. 1 and 2, a cut sheet 2 mounted on a movable portion l of a cut sheet mounting section is pressed against a sheet feed roller 3 by a spring 12. As shown in FIG.

In this state, when power is transmitted to the first platen 6 and the platen 6 rotates counterclockwise, the platen gear 8 attached to the end face of the platen 6 transmits the rotation to the idle gear 10. The idle gear 10 is rotatably attached to the tip of a planetary arm that is rotatably attached to the shaft of the platen 6. When the platen gear 8 rotates counterclockwise, the idle gear 10 moves to the center of the platen 6. It rotates about the shaft toward the roller gear 11 attached to the end surface of the shaft of the paper feed roller 3, meshes with the roller gear 11, and transmits the rotation. As a result, the rotation of the platen 6 is transmitted to the paper feed roller 3. Therefore, the cut sheet 2 pressed against the paper feed roller 3 by the spring 12 becomes ready to be fed.

Subsequently, the rotation of the platen 6 is controlled by the pressing force of the paper feed roller 3 and the spring 12 until the cut paper 2 is inserted between the platen 6 and the pressure roller 4, and a paper feed operation is performed. When the cut sheet 2 is inserted between the platen 6 and the pressure roller 4, the platen 6 is controlled to rotate clockwise. As a result, the cut sheet 2 is sent to the printing position. When the platen 6 rotates clockwise, the idle gear 10 moves away from the roller gear 11 around the axis of the platen 6, as shown in FIG. does not transmit rotation. Therefore, the next cut sheet 2 is not sent out.

When the platen 6 rotates clockwise, the cut sheet 2 is advanced to the printing position by the platen 6 and the pressure roller 4, and a printing operation is performed.When the printing operation is completed, the platen 6
and pressure roller 5, the paper is stored in a cut sheet storage section provided at the rear of the printer device.

By repeating the above operations, the paper sheets are sent out one sheet at a time from the contest paper loading section provided at the rear of the printer and printed, and the printed paper sheets are transferred to the paper storage section. It is possible to store it in.

〔Effect of the invention〕

As explained above, the printer device of the present invention automatically feeds the cut sheets one by one from the cut sheet loading section by rotating the platen, prints them, and transfers the printed sheets to the cut sheet storage section. This has the advantage that it can be stored in Therefore, it is possible to print on a cut sheet without using a sheet feeder, a cassette, a cassette tray, or a stylus, which has the effect of improving the operability for the user of the printer device.
