Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording apparatus equipped with a static electricity removal mechanism that removes static electricity charged on a recording medium such as recording paper.

[Conventional technology]

Traditionally, in order to remove static electricity that accumulates on recording paper,
A static electricity removal brush is provided near the paper ejection roller in the paper ejection section. By providing this static electricity removal brush, it is possible to prevent the recording sheets that are successively stacked on the stacker from adhering to each other, and to align the ejected recording sheets.

[Problem to be solved by the invention]

However, in such conventional recording devices, if static electricity is not removed sufficiently by the static electricity removal brush,
There is a problem in which the recording sheets overlap irregularly after being ejected due to residual static electricity.

SUMMARY OF THE INVENTION An object of the present invention is to provide a recording apparatus that can solve the problems of the prior art and can align recording objects after paper ejection.

[Means to solve the problem]

The present invention includes a platen that conveys recording paper while being pressed against a part of its circumferential surface, a stacker that sequentially accommodates the recording paper that is generally taken out from the platen, and a stacker that guides the recording paper that is taken out from the platen to the stacker. In the recording apparatus equipped with a vibrating paper ejection roller, an electric charge eliminating member is disposed on the paper ejection side of the paper ejection roller so that an elastic force for pressing the recording paper toward the stacker can be applied to the recording paper, and thereby the above-mentioned It is designed to achieve a purpose.

A brush capable of removing static electricity or a metal leaf spring can be used as the static eliminating member.

[For production]

The defrosting member only removes electricity by contacting the recording paper whose rear part is attached to the paper ejection roller with a moderate contact pressure, and removes electricity from the recording paper that has completely separated from the paper ejection roller by removing it from the stacker. A pressing force is applied to accommodate the recording sheets, and the recording sheets are aligned in sequence. Therefore, the static eliminating member has both a static electricity eliminating function and an aligning function.

〔Example〕

The present invention will be specifically described below with reference to FIGS. 1 to 4.

FIG. 1 is a schematic front view showing an embodiment of a recording apparatus according to the present invention.

In FIG. 1, 1 is a platen that transports the recording paper P while being wound around it, 2 is a paper discharge roller that discharges the recording paper P that has been peeled off from the surface of the platen 1 to the stacker side, and 3 is a paper discharge roller that covers the paper discharge roller 2. 4 is a paper guide provided with a rib on the opposite side of the paper ejection roller 2;
a stacker for sequentially stacking the recording sheets ejected by the 5
is disposed so as to be in contact with the surface of the recording paper P discharged by the paper discharge roller 2, and serves as a static electricity removal member that removes static electricity charged on the paper surface and presses the recording paper P toward the stacker 4. A brush 6 is a feed roller that presses and conveys the recording paper P at a predetermined position on the platen 1, and 7 is a paper pan that supports the feed roller 6 and guides the recording paper P.

In the above configuration, the recording paper P is inserted between the paper pan 7 and the platen 1, fed between the platen 1 and the feed roller 6, and is wound at the same speed according to the rotation of the platen 1. While being transported. The leading edge of the recording paper P exposed at the top of the platen 1 rises from the surface of the platen 1 along the guide, and is further separated from the surface of the platen 1 by a peeling section formed at the bottom of the stacker 4. The recording paper P peeled off from the platen 1 is inserted between a paper ejection roller 2 and a paper guide 3, is conveyed according to the rotation of the paper ejection roller 2, and is sequentially sent to the upper part of the stacker 4.

While the recording paper P is attached to the paper ejection roller 2, the recording paper P that comes out from the paper ejection roller 2 is stretched using the paper ejection roller 2 as a support point, and is in sliding contact with the elastic force of the static elimination brush 5. It is transported out and static electricity is removed one by one. When the recording paper P is separated from the paper ejection roller 2, there is no member to support the recording paper P.
The static eliminating brush 5 is pushed out toward the stacker 4 as shown in FIG. 2 by the restoring action due to its elastic force, and is housed in a fixed position on the stacker 4.

FIG. 3 is a schematic front view showing another embodiment of the present invention.

This embodiment differs from the previous embodiments in that instead of the bristle brush-shaped static elimination brush 5, an elastic metal leaf spring lO is used.
The reason is that it uses .

By making the elasticity of the slope spring 10 sufficiently weak, it can have the same function as the static elimination brush 5, and has the advantage of being easy to commercialize and reducing costs.

〔Effect of the invention〕

As is clear from the above, according to the present invention, there is provided a platen that conveys the recording paper while pressing it against a part of the circumferential surface, a stacker that sequentially accommodates the recording paper carried out from the platen, and a stacker that sequentially accommodates the recording paper carried out from the platen. In a recording apparatus including a paper discharge roller that guides recording paper to the stacker, an electric charge eliminating member is provided on the paper discharge side of the paper discharge roller so that an elastic force for pressing the recording paper toward the stacker can be applied to the recording paper. Since this is provided, static electricity can be removed and the recording sheets can be aligned with a simple configuration.
