A paper discharge guide 12 is provided near the bottom surface of the paper feed roller 1, and this guide 12 picks up the transmission document 4 that has passed between the paper feed roller 1 and the recording head 2, and the recording paper 6.
The paper feed roller 1 and the recording paper 6 are guided to a paper discharge tray 13 provided below the paper cylinder 6a.

Further, a light source 1 such as a fluorescent lamp is provided near the paper feed roller 1.
4 is provided, and this light source 14 is adapted to illuminate a reading position 16 set at a portion of the outer peripheral surface of the paper feed roller 1 directly below the recording head 2 . The reading position 16
An image sensor 17 is opposed to the image sensor 17 through a lens 16.

Incidentally, each of the parts 8 to 14, 16, and 17 is also supported by the main body of the apparatus.

FIG. 2 shows a drive mechanism for the paper feed roller 7, feed-out drive roller 8, and paper feed roller 1. As shown in FIG. In the figure, a motor 18 is directly connected to the rotating shaft of the paper feed row 21, and a pulley 19 is fixedly attached thereto. Further, a pulley 21 is attached to the rotating shaft of the paper feed roller 7 via a clutch 2o, while a pulley 23 is attached to the feeding drive roller 8 via a clutch 22. A belt 24 is wound around the pulleys 19, 21 and 23.

Next, the operation of this embodiment will be explained.

At the time of unreleased transmission, the clutch 20 is engaged, while the clutch 22 is disengaged. Therefore, the paper feed roller 1 is directly driven and rotated by the motor 18, and the pulley 19. Belt 24. While the paper feeding roller 7 is driven and rotated by the motor 18 via the pulley 21 and the clutch 2o, the feeding drive row 28 is not driven and rotated.

In this case, the transmission documents 4 stacked on the document table 6 are

one! Note that while being conveyed along such a route, the transmission document 4 is irradiated by the light source 14 at the reading position 16 . The reflected light then passes through the lens 16 to the image sensor 17.
The transmission document 4 is read by being imaged on the light-receiving surface.

Next, during reception, clutch 20 is disengaged, while clutch 22 is engaged. Therefore, the paper feed roller 1 is directly driven and rotated by the motor 18 in the same way as during transmission, and the paper feed roller 1 is directly driven and rotated by the motor 18, and the output roller IJ-19. Belt 24. While the feeding drive row 28 is rotated via the pulley 23 and the clutch 22, the paper feed roller 7 is not driven to rotate.

Therefore, the recording paper 6 fed out from the paper cylinder 6a is placed between the feeding drive row 28 and the feeding driven roller 9, and the cutter 10. Paper is fed between the paper feed roller 1 and the heat generating section 2a of the recording head 2 after passing between the recording paper push guides 112L and 11b, heated by the heat generating section 2a to perform recording, and then passed through the paper ejection guide. 12 and is outputted to 4 non-paper trays 13.

In this way, in this facsimile machine, one paper feed roller 1 serves as the paper feed roller for reading and the paper feed roller for recording, which were conventionally provided separately. Conventionally, this head 2 also functions as a member that presses the transmitted document against the paper feed roller for reading, which was provided separately from the head 2. Therefore, the device as a whole functions as a member that presses the transmitted document 4 and the recording paper 5. The mechanism configuring the conveyance path becomes simple, and manufacturing costs can be reduced and reliability improved.

In this embodiment, the clutches 22 and 20 are disengaged at the time of transmission and reception, so the recording paper 6 is fed during transmission, and the transmitted original 4 is fed during reception, so that the transmitted original 4 and the recorded The paper 6 does not interfere with each other.

In this embodiment, the recording paper 5 is cut into a length corresponding to the transmitted document by the cutter 10 located in front of the heat generating section 2a based on the document end detection signal sent from the transmitter. Even after the recording is completed, the recording paper 6 remains between the paper feed roller 1 and the heat generating section 2a, and there is no fear that the recording paper 6 will interfere with the feeding of the transmitted document 4 during the next transmission.

Note that, instead of providing two clutches as in this embodiment, the paper feed roller 7 and the feeding drive roller 8 may be driven by independent drive sources. In the above,
The transmission document 4 is illuminated by the light source 14, and the reflected light is imaged on the light receiving surface of the image sensor 17 through the lens 16, so that reading is performed. Instead of the lens 16 and the image sensor 17, a contact type image sensor or the like that does not require a lens system may be used.
