Abstract

PURPOSE:To simplify a mechanism and reduce its cost, by providing a paper discharge roller of semicircular cross section and by bringing the roller into contact with cut-off paper only after its cutting-off. CONSTITUTION:A paper discharge guide plate 20 and a paper discharge roller 19 of semicircular cross section are provided downstream to a cutter 14 for cutting off wound recording paper 11. The paper discharge guide plate 20 is placed so that the paper discharge roller 19 comes into contact with the plate when the roller is rotated. When the wound recording paper 11 is conveyed in the direction of an arrow (a) by a paper feed roller 12 and the cutter 14 is turned in the direction of an arrow (b), the paper discharge roller 19 of semicircular cross section is turned in the direction of an arrow (c) so that a piece of recording paper 15 cut off by the cutter 14 is pinched between the paper discharge roller and the guide plate 20. As a result, the cut-off piece of recording paper 15 is conveyed in the direction of the arrow (a) and put in a recording paper storage section 16. The paper discharge roller 19 is then returned to the original position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for discharging paper cut using a cutter in a facsimile IJ apparatus or similar apparatus at a temperature of .degree.

Conventionally, in the paper ejection device of a facsimile machine that uses rolled recording paper, a paper ejection roller is installed on the exit side of a cutter that cuts the recording paper.This paper ejection roller is independent of the paper feed roller. It is necessary to rotate the For this reason, in order to rotate the paper ejection roller, it is necessary to provide a dedicated drive source, or to use the drive source of the paper feed roller and separate it from the drive of the paper feed roller using a clutch, etc. . However, the former is economically disadvantageous, and the latter has a complicated mechanism.

An object of the present invention is to use a semicircular paper ejection roller to prevent the paper ejection roller from coming into contact with the recording paper while the recording paper is moving, and to rotate the semicircular paper ejection roller by the drive source of the cutter, thereby achieving economical efficiency. It is an object of the present invention to provide a paper ejecting device which eliminates disadvantages and mechanical complexity, and which makes it possible to simplify the drive of a paper ejecting roller and reduce costs.

The present invention will be described in detail below with reference to nine drawings.

FIG. 1 is a sectional view of a conventional paper ejection device, in which a roll of recording paper 11 is transported by a paper feed roller 12 and a paper ejection roller 13.
It is sent in the direction of arrow a. The one-rotation cutter 14 rotates in the direction of the arrow in response to a cut command to cut the recording paper. After this.

The paper feed roller 12 stops rotating, only the paper discharge roller 15 rotates in the direction of the arrow, and the cut recording paper 15 is fed in the direction of the arrow a and stored in the paper storage section 16. The recording device 17 has the role of printing on recording paper, and the pinch roller 18 has the role of feeding the paper. Paper feed roller 12.
Since the cutter 14 and the paper ejection roller 16 each need to have an independent driving source, the driving means is not shown.

FIG. 2 is a cross-sectional view of an embodiment of the paper ejecting device according to the present invention, showing the state before cutting the recording paper.

The third figure is a cross-sectional view showing the state after cutting the same recording paper as above. In this embodiment, one paper feed roller 12 rotates to move the arrow a.
A cutter 1 that cuts the rolled recording paper 11 that is fed in the direction
4, a paper discharge guide plate 20 and a semicircular paper discharge roller 19 are arranged on the rear side. The paper discharge guide plate 20 is arranged so as to be in contact with the semicircular paper discharge roller 19 when it rotates. In this embodiment, the paper feed roller 12 and the cutter 14 each have an independent drive source, and the semicircular paper discharge roller 19 is driven by the cutter 14 and the cutter 14.
This is done by connecting with a pair of gears, etc. Drive means are not shown.

The rolled recording paper 11 is fed in the direction of arrow a by a paper feed roller 12. At the same time as the cutter 14 rotates in the direction indicated by the arrow C in response to the cut command, the semicircular paper ejection roller 19 also rotates in the direction indicated by the arrow C.
Rotate in the direction. After the cutter 14 has completed cutting the rolled recording paper 11.

The semicircular paper discharge roller 19 contacts the paper discharge guide plate 20 via the cut recording paper 15. As a result, the cut recording paper 15 is sent in the direction of arrow a and is stored in the recording paper storage section 16.

By controlling the cutter 14 so that it always returns to its home position after rotation (control means not shown).

The semicircular discharge roller 19 can also be returned to its home position.

As explained above, the paper ejecting device according to the present invention is provided.

By using the semicircular paper ejection roller, the recording paper is ejected regardless of the rotation of the paper feed roller, and driving and control can be simplified.
