Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer capable of containing printed paper.

[0002]

2. Description of the Related Art Conventionally, there is known a printer capable of accommodating a sheet printed by a printing section. FIG. 4 shows a schematic configuration of such a printer. In the figure, reference numeral 2 denotes a printing section, which is composed of a platen 3 and a print head 4 which are arranged to face each other. A ribbon guide 5 for guiding a sheet is provided between the platen 3 and the print head 4. Further, 6 is a feed roller which cooperates with the bail roller 7 and is formed so that the paper discharged from the printing unit 2 can be conveyed. A stock box 8 capable of accommodating a sheet is disposed downstream of the feed roller 6 in the conveyance of the sheet. Further, between the feed roller 6 and the stock box 8, a paper pressing means (for example, a lumirror 19) capable of pressing the paper and guiding it to the stock box 8 is provided. Specifically, the lumirror 19 has its base end fixed to the transparent cover 9 that is a stationary body, and is configured to press the paper by utilizing its own elastic force.

[0003]

By the way, in the above-mentioned conventional printer, the paper pressing means (Lumirror 1
If 9) is left bent for a long time in a state where it is bent by a sheet of paper or the like, it may be plastically deformed and the pressing force against the sheet may change, which may cause a problem that the sheet cannot be smoothly guided to the stock box 8.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a printer which can prevent a paper pressing unit from being plastically deformed and can smoothly store a paper in a paper storage unit.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a feed roller for conveying a sheet discharged from a printing section, a sheet accommodating section disposed downstream of the feed roller for accommodating a sheet, and the feed. In a printer including a sheet pressing unit that can press a sheet between a roller and a sheet accommodating section and guide the sheet to the sheet accommodating section, a plurality of the sheet pressing sections are arranged in the axial direction of the feed roller. It is characterized in that it is formed from the plate-shaped member, the base end of the plate-shaped member is rotatably supported by a stationary body, and the tip end is in contact with the feed roller.

[0006]

In the present invention, the sheet sent out from the feed roller is accommodated in the sheet accommodating portion while being pressed by a plurality of plate-shaped members forming the sheet pressing means. At this time, each plate member has its base end rotatably supported by a stationary member and presses the sheet by using its own weight, so that it is not forcibly bent by the sheet or the like and is not plastically deformed. Absent.

Thus, the paper pressing means (plate member) can be prevented from being plastically deformed and the paper can be smoothly accommodated in the paper accommodating portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the printer according to this embodiment includes a printing unit 2, a feed roller 6, a paper storage unit (stock box 8), a transparent cover 9, and a paper pressing unit (11) which is a characteristic part of the printer. ) Is included.
The same components as those shown in FIG. 4 are designated by the same reference numerals, and the description thereof will be omitted or simplified.

Here, the sheet pressing means is formed of a plurality of plate-like members 11 arranged in the axial direction of the feed roller 6, as shown in FIG. As shown in FIG. 1, each plate-shaped member 11 is configured such that a base end portion 12 thereof is rotatably supported by a stationary body (a transparent cover 9 in this embodiment), and a tip end portion 13 thereof abuts on the feed roller 6. Has been done.

Next, the operation will be described. The sheet sent out from the feed roller 6 is accommodated in the stock box 8 while being pressed by the plurality of plate-shaped members 11. At this time, each plate-shaped member 11 has its base end 12 at the transparent cover 9
Since it is rotatably supported by and presses the sheet by utilizing its own weight, it is not forcibly bent by the sheet or the like and is not plastically deformed.

As a result, it is possible to prevent the plate-like members 11 from being plastically deformed and to smoothly accommodate the sheets in the stock box 8.

According to this embodiment, however, the sheet pressing means is formed of a plurality of plate-shaped members 11 arranged in the axial direction of the feed roller 6, and the respective plate-shaped members 11 are arranged.
Since the base end 12 of the sheet is rotatably supported by the stationary body (transparent cover 9) and the tip 13 is in contact with the feed roller 6, it is possible to prevent the sheet pressing means (plate member 11) from being plastically deformed. Thus, the paper can be smoothly stored in the paper storage unit (stock box 8).

According to the above embodiment, each plate member 1
1 is configured to press the sheet by using its own weight, but as shown in FIG. 3, the sheet is pressed by using the spring force of the spring (eg, the toggle spring 14) in addition to the own weight of the plate member 11. It may be configured to. With such a configuration, each plate-shaped member 1 is provided in order to reduce the size and weight of the printer.
Even if 1 is thin (that is, lightweight), it is possible to press the paper properly and smoothly guide it to the stock box 8.

[0014]

According to the present invention, the sheet pressing means is formed of a plurality of plate-like members arranged in the axial direction of the feed roller, and the base end of the plate-like members is rotatably supported by the stationary body. Moreover, since the leading end portion is in contact with the feed roller, it is possible to prevent the paper pressing means (each plate member) from being plastically deformed and to smoothly store the paper in the paper storage portion.
