Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile apparatus in which the first side of a roll of recording paper is used for recording facsimile reception, and the second side is used as a side for writing facsimile transmission documents.

BACKGROUND OF THE INVENTION Conventional facsimile apparatuses have a structure in which paper exclusively for reception recording and transmission originals are prepared separately, and a reception recording paper feeding path and a transmission original feeding path are provided separately.

Problems to be Solved by the Invention For this reason, most conventional office facsimile devices have become large in size, and cannot be used on a disk like a telephone.

The present invention overcomes these drawbacks by making the first surface of the roll recording paper the facsimile reception recording surface and the second surface the facsimile transmission document surface. It is an object of the present invention to provide a facsimile device which is significantly downsized by simultaneously using the back side and by simplifying the paper feeding route, and which can also reliably record reception.

Means for Solving the Problems In order to achieve the above object, the present invention provides a recording paper having a first side for recording facsimile reception and a second side for recording facsimile transmission documents. a conveyance means for conveying the recording paper along a path; a paper detection means provided on the conveyance path of the recording paper for detecting the presence or absence of the recording paper; and a paper detection means provided on a first surface side of the recording paper for detecting the presence of the recording paper; a recording head for forming an image on the recording paper; and a recording head provided on the second surface side of the recording paper;
a reading head for reading the image on the recording paper, the recording head is provided downstream of the paper detection means in the recording paper transport direction, and the distance from the paper detection means is at least one page of the received image. They are spaced apart.

Function Therefore, in order to use the front side (first side) and back side (second side) of the roll recording paper as facsimile reception recording paper and facsimile transmission document, it is possible to record by sandwiching the recording paper in the same paper feeding path. Since the head and the reading head can be arranged, the device can be significantly downsized. Furthermore, since the recording head is provided at a distance L of one page or more from the paper detection sensor, at least one page is retained within the facsimile body, so there is no possibility of running out of recording paper during facsimile communication. Further, since the reading heads are arranged within the distance L (l<L), the recording paper feeding path can be kept at the minimum necessary distance.

Embodiment The figure is a sectional side view of an embodiment of a facsimile apparatus according to the present invention. 1 is a roll recording paper made of thermal recording paper wound into a roll, 2 is a feed roller, 3 is an upper part of the main body, 4 is a lower part of the main body, 5 is an original table, 7 is a pressure-bonding feed roller, 8 is a reading device such as a CCD, etc. The head is provided on the second side of the recording paper. 9 is a light source such as a fluorescent lamp, and 10 is a recording head, typically a heat-sensitive recording head, which is provided on the first side of the recording paper. A paper detection sensor 11 detects the presence or absence of recording paper. The reading head 8, light source 9, and pressure feed roller 7 are provided in the opening/closing section 6.

Here, the size of the document table 5 indicates the size B of one page of facsimile communication, and the distance L between the recording head 10 and the paper detection sensor 11 is larger than the length B of one page. The reading head 8 is arranged at a distance l within this distance L.

The roll recording paper 1 is fed in the direction of arrow A by a feed roller 2 and a pressure feed roller 7.

When the operator creates a transmission document on the document table (second side) of the recording paper 1 on the document table 5 and presses the facsimile transmission button, the feed roller 2 and pressure roller 7 are driven and the reading head 8 reads and scans the document. and send a facsimile. When there is a call for facsimile communication from the other party, the feed roller 2 and the pressure feed roller 7 are driven and the recording head 10 scans and records on the second surface of the recording medium, as in the case of transmission, and the facsimile receiving surface Record. Here, when the recording paper 1 is consumed for transmission and reception and finally runs out, the paper detection sensor 11 detects the end of the paper and displays on the panel display that the recording paper is running out. The device control circuit unit instructs to stop recording from the next page onwards.

Here, from the paper detection sensor 11 to the recording head 10
Since the distance to FAX is set as distance L which is more than one page of facsimile communication, at least one page is held in the device, so there is a possibility that the paper will run out during facsimile communication and information will be lost midway. There isn't. Further, operating the recording head 10 without the recording paper 1 shortens the life of the recording head and also has an adverse effect on the pressure feeding roller, but such problems can be prevented.

Effects of the Invention As described above, the present invention has a configuration in which facsimile reception and transmission are performed using both sides of recording paper.
In addition, since the distance between the paper detection sensor and the recording head is set to a distance L that is equal to or more than one page, it is possible to obtain a facsimile device that can be miniaturized and performs accurate facsimile communication without malfunction. .
