Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] In the present invention, the opposing wall surfaces of a reading unit and a recording unit, which are arranged at positions substantially line-symmetric with respect to the rotation axis of one feed roller, cause the original and The present invention relates to a facsimile device that pushes out each recording sheet and sends it out.

[Conventional technology]

In a conventional facsimile apparatus of this type, a reading unit and a recording unit are pressed against one feeding roller, and the feeding roller has a large friction coefficient like a rubber roller to facilitate feeding of an original or recording paper. I'm wearing.

Avoid causing the surface of the feed roller to come into direct contact with the surface of the reading unit or recording unit to cause damage, and automatically separate the reading unit and recording unit from the feeding roller under the conditions of transmission, reception, and copying. There is.

When using a roll type of recording paper, the recording part is sent to the outside of the cutting unit at the end of recording and then cut, but the rotation of the feed roller is prevented as much as possible because it is a reading unit that is in close contact with the feed roller. .

[Problems to be Solved by the Invention]

As described above, the conventional facsimile machine automatically disengages unnecessary portions of the reading unit and the recording unit from the feed roller when feeding a document or recording paper in close contact with one feed roller in order to avoid unnecessary feeding. However, for the roll type recording paper, only the recording portion is sent to the outside of the cutting unit at the end of recording, and since there is no mechanism that does not perform its function, the recording paper from the recording unit to the cutting unit is wasted. There was a problem.

An object of the present invention is to provide a facsimile apparatus that solves the above problems by detecting that the reading unit is separated from the feed roller and reversing the feed roller by a predetermined amount.

[Means for solving the problem]

A facsimile apparatus according to the present invention is a facsimile machine in which a wall surface of a reading unit and a recording unit facing each other about an axis of rotation of one feed roller are opposed to each other while the original and the recording paper are pressed against the feed roller. In the apparatus, a detection unit that has means for separating the reading unit from the feed roller and detects a reception state in which the reading unit is separated from the feed roller, a cutting unit that cuts the recording sheet, and a receiving state. And a control unit which reverses the feed roller by a predetermined amount when the reading unit is separated from the feed roller and the recording paper is cut by the cutting unit.

[Action]

When the reading unit is separated from the feed roller in the receiving state, the facsimile apparatus of the present invention by the above-mentioned means returns the leading edge of the recording paper from the cutting unit position to the recording position of the recording unit by the reverse rotation of the feed roller and wasteful blank space. Can be eliminated.

〔Example〕

Next, a facsimile apparatus of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.
In FIG. 1, the facsimile device has a feed roller 1, a reading unit 2, a recording unit 3, a cutting unit 4, a controller 5, and a detector 6, and a recording paper 7 is sandwiched between the feed roller 1 and the recording unit 3. And passes through the cutting unit 4.

The feed roller 1 rotates under the control of the control unit 5. During transmission and copying, the reading unit 2 presses against the feed roller 1 to sandwich the document, and reads the screen that moves by rotation of the feed roller 1 and converts it into an electric signal. When receiving and copying, the recording unit 3 presses against the feed roller 1 to sandwich the recording paper, and records an image by an electric signal on the recording paper that moves by the rotation of the feed roller 1. Cutting unit 4
Cuts the recorded recording paper so that it can be ejected and separates it from the roll recording paper.

The control unit 5 rotates the feed roller 1 in the forward direction when reading a document and recording on a recording sheet. At the end of recording,
The control unit 5 moves the recording paper 7 until the recording portion of the recording paper 7 reaches the outside of the cutting unit 4, so that the feed roller 1
To rotate. Further, when the detection unit 6 detects that the reading unit 2 is detached from the feed roller 1 and receives the notification in the receiving state, and the control unit 5 cuts the recorded recording paper 7 by the cutting unit 4, When both conditions are overlapped, the control unit 5 rotates the feed roller 1 in the reverse direction so that the leading end of the recording paper 7 cut by the cutting unit 4 is moved to the recording unit 3
To the contact portion of the feeding roller 1 with the feeding roller 1, that is, the recording portion.

Next, the detection unit 6 will be described with reference to FIG. FIG. 2A is a configuration diagram showing an example of the detection unit.
The detector has a detector 61 and an open contact 62. The detector 61 detects the closing of the open contact 62. Open contact 62 has cam 8 R
When the reading unit 2 rotates away from the feed roller 1, the reading unit 2 moves to close the electric circuit.

FIG. 2B is a configuration diagram showing another example of the detection unit. Also in FIG. 2 (B), the detection unit includes a detector 61 and an open contact 63.
Have. The open contact 63 closes the electric circuit depending on the rotation of the cam 8 that moves the reading unit 2, that is, the position where the reading unit 2 is released from the feed roller 1.

In the above-described embodiment, the detection section outputs and closes the electric circuit by the open contact, but the detection means is not limited to the above description.

〔The invention's effect〕

As described above, according to the facsimile apparatus of the present invention, when it is detected that the reading unit is separated from the feed roller and when it is notified that the recording sheet is cut, the control unit reverses the feed roller to perform recording. Since the paper is configured to move the cut tip to the recording position of the recording unit, the reading surface of the reading unit is moved from the cutting unit to the recording unit without being damaged by the feed roller. Therefore, it is possible to obtain the effect of eliminating the wasted margin of the recording paper.
