Abstract

PURPOSE:To prevent paper from being folded and jammed by cutting the continuous form drawn out from a roll on the downstream side of a recording portion, and then reversing the roll to unwind the reversed continuous form. CONSTITUTION:A recording apparatus 21 provided on a receiving portion 2 of a facsimile comprises paper feeding means 26 including a paper feed roller 27 for feeding out a roll recording paper 23 stored in an enclosure box, which can be rotated in (a)-direction and in (b)-direction by a driving source such as a pulse motor or the like. The recording paper fed out by the means 26 is printed by a recording head 24 and is laterally cut corresponding to one sheet document 5 by an automatic cutter 28 to be discharged from an outlet 20. In this case, on the completion of receiving and recording, after one sheet continuous form 23' is cut, the paper feed roller 27 is reversed to pull back the leading end of the continuous form 23' from the cutting place 31 in the automatic cutter 28 to a recording portion 25. Thus, the generation of a blank portion of the continuous form is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention is used in a recording apparatus C2, such as a facsimile machine, which is equipped with a paper feeding means capable of reverse feeding and a recording paper roll.

Prior art In a conventional recording device such as a facsimile, the continuous paper t fed out from the recording paper roll is cut at the downstream side of the recording section and then reversed to cut the continuous paper from the recording section on the continuous paper. However, it is necessary to provide a space inside the device to store curled paper by pulling it back, and if this space cannot be made large enough due to the miniaturization of the device, the paper may be folded into small pieces. There was a fear that jams would occur.

(／→ Purpose of the Invention This invention prevents the occurrence of folding, jamming, etc. of the paper by winding the paper Z on a recording paper roll that has been reversely fed and pulled back.
It is intended to prevent

B) Structure of the Invention This invention cuts the continuous paper fed out from a recording paper roll on the downstream side of the recording section, and then reversely feeds the continuous paper using a paper feeding means capable of reverse feeding. In a recording device such as a facsimile machine, which has a blank space from the recording section to the cutting point, when the paper is reversely fed up the paper feeding means, the reversely fed continuous paper is inserted into the recording paper slot. Reverse the file and rewind like 7 (it's a rainbow).

TS) Embodiment Figures 1 and 2 show a facsimile machine equipped with device Z in which this invention is implemented, (1) is a housing, and a receiving section is provided on the upper left side and lower right side of the housing. (2) and the transmitter (
3).

Transmission m5 (3J is the stacked original (5) 7! inserted from the insertion slot (4), which is pressed against the separation roller (7) by the feed spring (6) and applied to the outer periphery of the separation roller (7). The rubber surface of the separating plate (8) prevents the upper sheet of paper from being transferred, and feeds the original document (5) one by one one by one, starting from the lower layer. While the pair of paper feed rollers (9) C1O and tension rollers 3+2 are being transferred under pressure, the reading area is illuminated by a fluorescent lamp 041C2, and the reflected light is read after the glass αω and the reflecting mirror are opened. The original is sent to the photoelectric conversion unit αη for photoelectric conversion, and then the original (5) t guide Cl8)
11, and the temperature discharge port is also configured to discharge from Q.

圓 is a recording device according to an embodiment C of the present invention, which is provided in the receiving section (2). Q snoring recording paper roll (to)
storage box, (to) is the recording head forming the recording section Q group,
(21 is a paper feeding means capable of reverse feeding, and paper feeding roller C!
.eta., and a drive source (not shown) such as a pulse motor that rotates the sheet feeding roller by switching between the forward direction indicated by the solid line arrow a and the reverse direction indicated by the dotted line arrow. The paper feed roller (27) is pressed against the recording roller C24), and also functions as a platen roller. The kan is an automatic cutter installed downstream of the recording section E. It consists of a fixed blade (7) and a rotating blade (7).
2, the continuous paper is cut in the width direction by one rotation using a Do motor or the like. The cut recording paper comes into contact with the guide (18) and is ejected from the ejection port (4) to the outside of the facsimile. ), after the reception recording is completed, the recording paper is cut by feeding the recording paper so that the trailing edge of the recorded image is from the recording section (c) to the cutting point clB, and after cutting.

Paper feed roller c! ? ) is reversely fed and pulled back from the leading edge <2S:>W cutting point CD of the continuous paper @ to the recording section (c) as shown in FIG. Therefore, during this period (
You can also leave the margins of the paper (indicated by arrow O) blank.

The recording device is configured such that the paper feeding roller Q1 of the paper feeding means (c) is brought into contact with the outer periphery of the recording paper roll and rotates by Y. Specifically, in the recording apparatus, the paper feed roller c!31 is installed parallel to the rotation axis of the support roller I:3 attached to the storage box, The recording paper roll (2η) is stably supported by making parallel line contact at two places between the paper feed roller (2η) and the support roller 0. ) is narrower than the minimum outer diameter after the end of feeding until the end of feeding. The recording paper suddenly appears to be rewound onto the roll (c).

(f) Effects of the Invention The present invention is configured as described above, and since the continuous paper that has been fed backwards is rewound by reversing the recording paper roll, it is possible to prevent the paper from bending and folding. At the same time, the storage space for the bent part of the paper can be omitted from the facsimile or other device, making the device Z compact.Furthermore, the paper feeding roller of the paper feeding means is brought into contact with the outer periphery of the recording paper roll, and the recording When configured to rotate the paper roll, the paper feeding means also serves as a dedicated driving means for the recording paper roll, thereby simplifying the apparatus and reducing costs.

Claims (1)

[Scope of Claims] 1) The continuous paper sheet fed out from the recording paper roll is cut on the downstream side of the recording section, and then reversely fed by a paper feeding means capable of reverse feeding, thereby cutting the continuous paper sheet. In a recording device such as a facsimile machine that has a blank area from the recording section to the cutting point, when the paper is reversely fed by the paper feeding means, the continuous paper that has been reversed is reversed by reversing the recording paper roll. It's time to unwind! Features recording devices such as facsimile machines. 2) The paper feeding means has a paper feeding roller that can be freely operated in forward and reverse directions, and is configured so that the paper feeding roller is brought into contact with the outer periphery of the recording paper roll to rotate the recording paper roll. A recording device such as a facsimile machine according to claim 1.
