The image is formed on the light receiving section No. 4. Furthermore, an operation panel 50 is provided on the top of the optical system cover 30 to perform various operations on the facsimile apparatus. In this embodiment, the original is set face up, and since the operation panel 50 is provided on the optical system cover, the user can perform the transmission operation while checking the contents of the original 47.

A recording paper plate 35 is provided at the front inside the main body housing 21, and a roll-shaped thermal recording paper 36 whose recording surface is wound inward is mounted on the recording paper plate 35.
A paper tube 36a is rotatably housed therein. Further, a recording head 37 is provided below the paper feed roller 23, with one end thereof rotatably supported by a main shaft 38 provided on the upstream side of the roller in the recording paper running direction. A spring 40 is interposed between the recording head 37 and the main body housing 21, and this spring 4
0, the recording head 3 is moved so that the heat generating part 37a of the recording head 37 is pressed against the outer peripheral surface of the paper feed roller 23.
7 is energized.

A solenoid 3 is located near the recording head 37.
9 is provided, and the tip of the movable portion of this solenoid 39 is rotatably connected to the recording head 37. A guide shaft 51 is provided between the paper tube 36a and the paper feed roller 23, and the recording paper 36 pulled out from the paper tube 36a is moved along the guide shaft 51.
The paper is supplied between the outer peripheral surface of the paper feed roller 23 and the heat generating section 37a of the recording head via the paper feed roller 23.

On the other hand, a recording paper receiving portion 41 is provided at the upper rear portion of the main body housing 21 . Between the paper feed roller 23 and the recording paper receiving section 41,
A cutter 42, an upper paper discharge guide 43, a lower paper discharge guide 44, and a paper discharge roller 45 are provided in this order from the paper feed roller 23 side. The paper ejection roller 45
is adapted to be driven by a drive device (not shown), and its outer peripheral surface is connected to the lower paper ejection guide 4.
It is pressed against the rear end of 4. Reference numeral 46 denotes a power supply/circuit section provided at the rear inside the main body housing 21.

Next, the operation of this embodiment will be explained.

First, at the time of transmission, the solenoid 39 is turned on, the movable part of the solenoid 39 is retracted, the recording head 37 is rotated in the direction of arrow C against the spring 40, and the heat generating part 37a is connected to the paper feed roller 22.
separated from the outer peripheral surface of the Therefore, in this embodiment, even if the paper feed roller 23 is rotated by the drive device during transmission, the recording paper 36 supplied between the heat generating section 37a and the paper feed roller 23 will be conveyed. There isn't.

Further, the solenoid 25 is also turned on, the movable part of the solenoid 25 is pushed out, the document stopper lever 26 is rotated in the direction of arrow B, and the tip of the lever 26 is separated from the outer peripheral surface of the paper feed roller 23. Therefore, the transmission documents 47 stacked face up on the document feed table 22 are not obstructed by the document stopper lever 26 and can be transferred to the separator 24 without being obstructed by the document stopper lever 26.
and the outer peripheral surface of the paper feed roller 23. Therefore, even after the transmission document 47 is placed on the document feed table, the contents to be transmitted can be easily confirmed since the transmission document 47 is face up.

The original 4 thus supplied between the separator 24 and the outer peripheral surface of the paper feed roller 23
7 is separated one by one by a separator 24,
Further, the paper is conveyed as the paper feed roller 23 rotates, and is ejected to the document receiving tray 29 via the document guide section 28 .

Further, while the document 47 is being conveyed to the paper feed roller 23 as described above, the light emitted from the fluorescent lamp 31 and reflected by the document 47 in the reading device A passes through the mirror 32 and the lens system 33. An image is formed on the light receiving section of the image sensor 34. and,
As a result, the image information of the original document 47 is read one after another.

At this time, dust such as paper powder is generated as the original 47 is transported and separated, but since the optical system is provided above the original transport path, the optical system is rarely contaminated. Further, in the case of this embodiment, since the fluorescent lamp 31 is provided apart from the power supply circuit section 46, the heat generated from the fluorescent lamp 31 does not have an adverse effect on the power supply circuit section 46.

On the other hand, during reception, the solenoid 25 is turned off. Therefore, since the tip of the document stopper lever 26 is moved toward the outer peripheral surface of the paper feed roller 23, even if a document 47 is placed on the document feed table 22, the document 27 is stopped by the document stopper lever 26. The separator 24 and paper feed roller 23
It is not possible to enter that part. That is, in this embodiment, the original document 47 is not transported during reception.

Further, since the solenoid 39 is also turned off, the force of the spring 40 causes the heat generating portion 37a of the recording head 37 to
is pressed against the outer peripheral surface of the paper feed roller 23 via the recording paper 36.

Therefore, when the paper feed roller 23 is rotated,
From the paper tube 36a through the guide shaft 51 to the heat generating part 3
The recording paper 36 fed between the paper feed roller 7a and the outer peripheral surface of the paper feed roller 23 is conveyed according to the rotation of the paper feed roller 23 while being recorded on the heat generating part 37a, and is passed through the cutter 42 and the paper ejection guide 43. and 44,
Then, the paper is ejected to the recording paper receiving section 41 after passing between the paper ejection roller 45 and the lower paper ejection guide 44. Here, the cutter 42 cuts the recording paper 36 conveyed as described above according to the recording length. In this embodiment, since the recording surface of the recording paper is rolled inward, rubbing occurs between the paper tube 36a and the recording paper plate 35 as the recording paper 36 is conveyed. Since it is wound, dust in the recording paper plate 35 will not adhere to the recording surface or scratches will occur on the recording surface.

Note that while the solenoid 25 is turned on and the document stopper lever 26 is rotated in the direction of arrow B, the solenoid 39 is turned off and the heat generating portion 37a is pressed against the paper feed roller 23 via the recording paper 36 by the force of the spring 40. In this way, the original 47 and the recording paper 36 are conveyed at the same time, so that while the original 47 is being transmitted, its contents can be copied through the recording head 37 at the same time.

In this facsimile machine, one paper feed roller 3 functions as both a reading roller and a recording roller, so the number of rollers can be reduced, and two systems are required for the reading roller and recording roller in the past. The hot roller drive mechanism can also be made into one system, and the number of parts can be reduced for the entire device.

Effects of the Invention As is clear from the above description, the present invention makes it possible to share the rollers for conveying the transmitted document and the rollers for press conveying the recording paper, and to move the rollers between the shared rollers from the rear upper part of the apparatus to the front lower part of the apparatus. The transmission document transport path and the recording paper transport path are provided substantially parallel to each other, and the recording head is rotated about a fulcrum provided upstream of the roller in the recording paper traveling direction to separate it from the roller during transmission. With this configuration, the number of parts can be reduced because the rollers are shared, and by providing a transmission document transport path and a recording paper transport path across the shared rollers, the device can be made more compact. In addition, it is possible to achieve the effect that while the rollers can be shared, the recording head can be rotated and separated from the rollers, thereby preventing the recording paper from being conveyed during transmission. .
