JPH05542A - Paper presser - Google Patents

Abstract

PURPOSE:To obtain a paper presser which neither injures fingers nor requires labor by a method wherein a pair of rollers which a sheet material is put between, and a pressure means which pressures the pair of rollers in directions opposed to each other, are provided. CONSTITUTION:When a sheet paper group is put between a pair of paper presser rollers 20 to be pulled along a guide part 24, the sheet paper group is pressured with a pair of the paper presser rollers 20 by action of a coil spring 22, and wrinkles, swelling, etc., can be restrained. Further, a roller shaft 21 is moved according to a thickness by which the sheet paper group is piled at that time, and a gap between the paper presser rollers 20 is requlated. Therefore, only by putting the sheet paper group between a pair of the paper presser rollers 20 to be pulled wrinkles and swellings of the sheet paper group can be restrained and finger is not damage nor is labor required.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention utilizes the pressure when passing between a pair of combined rollers to make the paper wrinkle,
The present invention relates to a pressure paper device that suppresses bulges and the like.

[0002]

2. Description of the Related Art A conventional pressure paper device has been constructed such that paper sheets are squeezed with fingers or sandwiched between two objects having a flat surface to apply pressure.

[0003]

However, the conventional pressure paper device requires a great deal of trouble in the structure in which the finger is injured due to friction with the paper sheets or the pressure is applied by sandwiching between two objects. .

The present invention has been made to solve the above problems, and an object of the present invention is to provide a pressure paper device which does not hurt a finger or requires much labor.

[0005]

In order to solve the above problems, in the present invention, a pair of rollers for sandwiching a sheet material,
And a pressing means for pressing the roller pair in a direction facing each other.

[0006]

In the present invention having the above construction, when the sheet material is sandwiched between the pair of rollers and pulled, the sheet material is pressed by the pair of rollers by the action of the pressing means, and the sheet material is wrinkled, bulged or the like. Can be suppressed.

【Example】

(Embodiment 1) FIG. 1 is a drawing of a printer main body showing the features of the present invention best. In FIG. 1, 11 is a paper discharge tray from which paper sheets as a sheet material which has been developed and fixed are discharged. 12 is an operation panel for operating / inputting the printer,
Reference numeral 13 is an insertion port of a paper feed cassette, and 14 is a pressure paper device for performing pressure paper of paper sheets.

FIG. 2 is a drawing showing the construction of the pressure paper device 14, 20 is a pressure paper roller pair as a roller pair for picking up paper sheets, and 21 is a pressure paper roller pair 20 depending on the thickness of the paper sheets.
, 22 is a roller shaft, and 22 is a coil spring that presses each roller of the pressure paper roller pair 20 in a direction opposite to each other,
Reference numeral 23 denotes a frame of the pressure paper device, which forms a guide portion 24 for paper sheets. Here, the roller shaft 21 and the coil spring 22 form a pressing means 25.

In the present embodiment having the above-mentioned structure, when the paper sheet is sandwiched between the pair of pressure paper roller pairs 20 and pulled along the guide portion 24, the paper sheet is compressed by the action of the coil spring 22. Pressure is applied by the roller pair 20, and wrinkles, bulges and the like can be suppressed. At this time, the roller shaft 21 moves according to the thickness of the stacked sheets, and the spacing between the pressure paper roller pair 20 is adjusted.

As described above, according to the present embodiment, it is possible to suppress the wrinkles and bulges of the paper sheets by only sandwiching and pulling the paper sheets between the pair of pressure roller rollers 20, and to hurt the finger. , It does not take time and effort.

Another embodiment of the present invention will be described below. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. (Embodiment 2) In FIG. 3, the pressure paper device 14 is incorporated in an upper cover 31 of a paper feed cassette, and 32 is a cassette body.

With this structure, the first embodiment
In addition to the effect of, it is easy to manufacture and install, and it can be used for the current cassette. (Embodiment 3) FIG. 4 shows the pressure paper device 14 which can be used alone. With such a configuration, in addition to the effects of the first embodiment, the pressure paper device 14 is manufactured independently.
It is available for sale and has no impact on current printers. Further, the pressure paper device 14 alone can be attached to the printer body.

[0013]

EFFECTS OF THE INVENTION By sandwiching a sheet material between a pair of rollers and pulling it, wrinkles, bulges and the like of the sheet material can be suppressed without injuring a finger or requiring time and labor.
