Therefore, the number of parts increases, which poses a problem in that it imposes restrictions on the miniaturization and cost reduction required for design.

The present invention has been made in view of the above-mentioned problems, and uses the same roller to transport the document during transmission and transport the recording paper during reception.
An object of the present invention is to provide an information communication device that can reduce the number of parts and downsize the device by using the same drive system.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a recording head around a common paper feed roller connected to a drive source, which presses recording paper against the paper feed roller to perform printing. , a pinch roller that presses the document against the paper feed roller and conveys it; a document reading unit that reads the document conveyed by the feed roller; This apparatus has a configuration in which a guide is provided between the feeding roller and the recording head.

With the above-described configuration, the present invention allows the feeding roller to rotate and convey the recording paper during reception and recording, and to perform recording on the recording head, and the feeding roller to rotate and convey the document during transmission. Then, the original can be read by the original reading means. Here, since the document transport and the recording paper transport are carried out by a common feeding roller, the transport system is shared, the drive source can also be shared, the number of parts is reduced, and the overall size can be made smaller. . 1. After the original is read, it is ejected through the space between the feeding roller and the recording head (between the recording paper and the feeding roller), so the original ejection path and the recording paper ejection path are common. In addition, the passage structure can be simplified.

Embodiment FIG. 1 is a schematic side view of a facsimile apparatus according to an embodiment of the present invention, and FIG. 2 is a schematic side view of a part of the facsimile apparatus, showing a state in which a document is being conveyed. In FIGS. 1 and 2, reference numeral 1 denotes a feeding roller, which is connected to a drive source (not shown) capable of forward and reverse rotation. 2 is a recording paper, 3 is a thermal recording head that presses the recording paper 2 against the feeding roller 1 to record, 4 is a spring that presses the recording head 3 against the feeding roller, and 5 is a document to be sent. , 6 are pinch rollers that press the document against the feeding roller 21, and are pressed against the feeding roller 1 by a pressing spring (not shown).

7 is a light source that illuminates the surface of the feeding row 21 at the document reading position 8 near the pinch roller 6; 9 is a mirror that further reflects the light from the light source 7 reflected by the feeding roller 1; 10 is a
It is an image sensor that receives the light reflected by the mirror 9 and converts it into an electrical signal.

These light source 7, mirror 9, and image sensor 10 constitute a document reading unit that reads the document conveyed by the feeding roller 1 and the pinch roller 6.

Reference numeral 11 denotes a guide that guides the leading edge of the document that has passed between the feed roller 1 and the binder row 26 between the feed roller 1 and the recording head 3; 12 is a document sensor; The presence or absence of a document is detected when the document is inserted into the document.

14 is a cutter.

Although not shown in the drawings, if the feeding roller 1 rotates in the direction of the arrow and conveys the recording paper 2 and the original 5 as normal rotation, the recording gutter 3 is moved against the spring 4 when the drive source is reversed. A cam is provided that lifts up the recording head 3 to release the pressure on the feeding roller l. This cam does not rotate when the drive source rotates in the normal direction, but rotates when the drive source rotates in the reverse direction again to release the pushing up of the recording head 3.

Furthermore, a clutch is also provided that disconnects the drive source from the feed roller 1 when the drive source is reversed.

The operation of the facsimile machine having the above configuration will be explained below.

In the normal standby state, the recording paper 2 is passed between the recording head 3 and the feeding roller 1 as shown in FIG. 1, and the recording head 3 presses the recording paper 2 against the feeding roller 1. There is. The original original has not been read, and the original sensor 12 is in an off state.

At the time of reception, the drive source rotates normally, and the feeding roller 1 rotates in the direction of the arrow to convey the recording paper 2 pressed by the recording head 3, and at this time, information is printed and recorded by the recording head 3. When recording is completed, the recording paper 2 is fed and stopped at position 1 of the printer 14, and enters a standby state.

During transmission, when the original 5 is inserted into the original insertion section 13, the original sensor 12 is turned on, and the drive source is reversed (feeding roller 1
(stopped state), push up the recording head 3 and release the recording head 3.
The suppression of the feed roller 1 is released. Therefore, the pressure on the recording paper 2 by the recording head 3 is released. Thereafter, the drive source rotates normally, and the feeding roller 1 rotates in the direction of the arrow to convey the original 5 through the original reading position 8. On the way,
Light from light source 7 is reflected on the surface of the document, and the reflected light is guided to image sensor 10 via mirror 9, where image information on the document is read and transmitted. The original 5 that has passed through the original reading position 8 is guided by a guide 11 and advances to the lower side of the recording paper, passes between the feeding roller 1 and the recording paper 2, and is ejected.

After reading the original, the drive source is reversed to release the pressure on the recording head 3, and the recording head 3 is again pressed against the feeding roller 1, returning to the original standby state.

During a copying operation, when the original 5 is inserted into the original insertion section 13, the original sensor 12 is turned on, the drive source is reversed, and the pressure on the recording head 3 is released. Thereafter, the drive source rotates in the normal direction and conveys the original 5 to the original reading position 8. Here, the drive source reverses and releases the pressure on the recording head 3, so that the recording head 3 is pressed by the feed roller 1 and presses the recording paper 2 against the feed roller l. Next, the drive source rotates normally, and the original 5 and the recording paper 2 are conveyed. Original 5, original reading position 8, light source 7
The reflected light is sent to the image sensor 10 via the mirror 9, and the image information is read.

At the same time, the image information is printed and recorded on the recording paper 2 by the recording gutter 3. The original 5 is sequentially conveyed, conveyed along the guide 11 to the back side of the recording paper 2, passes behind the recording paper between the recording head 3 and the feeding roller 1, and is ejected simultaneously with the recording paper.

? E. During the copying operation, the original 5 and the recording paper 2 are transported simultaneously, and recording is performed in parallel with reading, so the memory for storing the scanned information has a small capacity (approximately one page of the original). ) is fine.

Effects of the Invention As is clear from the above explanation, the present invention conveys and records the recording paper by pressing the recording gutter on the feeding roller, and also presses the pinch roller against the same feeding roller. Since the document is conveyed and the document being conveyed is read by the document reading means, the recording paper and the document can be conveyed by a common feeding roller, and the document after being read can be transferred to the recording head by a guide. Since the document is configured to be guided between the feed roller and the recording paper, the document can be ejected along the same route as the recording paper, and by sharing the recording paper conveyance system and the document conveyance system, the number of parts can be reduced and the device can be made more compact. It has the effect of being able to
