[Detailed Description of the Invention] The present invention includes a receiving system that receives facsimile information, records it on recording paper between a recording head and a capstan roller, and then transfers the information to a cutter section and cuts it.
Regarding a facsimile device equipped with a transmission system that feeds a transmission document to a reading section, reads it, and transmits it,
The aim is to reduce costs by reducing the number of parts used, and to make the product smaller and lighter.

FIG. 1 is a cross-sectional view of the mechanical parts of a receiving system and a transmitting system of a conventional facsimile device, with the left side of the figure being the front of the device and the right side being the back. Reference numeral 1 denotes a roll of paper, and a continuous recording paper 2a unwound from the roll of paper 1 is transferred between a capstan roller 3 and a recording head 4, where facsimile information is recorded using a thermal method or the like. Ru. The recording paper 2a is rotated by the capstan roller 3 in the direction of arrow _a .
After facsimile information is recorded while the paper is continuously fed, it is transferred to the cutter section 5. The cutter part 5 consists of a fixed blade 6 and a movable cutter blade 7.
By rotating the movable cutter blade 7 in _two directions indicated by the arrow a, the recorded recording paper is cut, but the movable cutter blade 7 is normally spaced apart from the fixed blade 6. At the tip of the cutter section 5, a paper guide 8, a discharge roller 9, a pinch roller 9p, and a stacker 10 are arranged in this order. The recorded recording paper 2b has a movable cutter blade 7 and a fixed blade 6.
The paper passes through the paper guide 8, is guided by the paper guide 8, is sandwiched between the ejection roller 9 and the pinch roller 9p, and is sent onto the stacker 10 by the ejection roller 9 and the pinch roller 9p. Then, the reception record for one page is completed,
When the end of the recording area of the recording paper 2b is fed to the position of the cutter section 5, the movable cutter blade 7 rotates in the direction of arrow _a2 to cut the paper. The cut recording paper is then transported by the ejection roller 9 and the pinch roller 9p,
It is discharged into the stacker 10. When the next reception recording is performed, the capstan roller 3 is reversed just before recording starts, and the leading edge of the recording paper 2a is returned to the vicinity of the print head 4 before printing, thereby creating a large margin at the leading edge of the paper. I'm trying not to be able to do it.
A reflective photo sensor 11 between the cutter section 5 and the capstan roller 3 detects the presence or absence of recording paper in the receiving recording standby state, and also detects a black mark on the back side of the recording paper provided near the end of the recording paper. Generates an alarm signal to notify that there is little paper left. A detection switch 12 for detecting a paper jam is provided between the cutter section 5, the discharge roller 9, and the pinch roller 9p.

On the other hand, a document hopper 13 is provided above the device, in which a document 15a for transmission is stacked.
When the document 15a is detected by the document presence detection switch 14, the drive motor of the transmission system
The pull-in roller 16, transport roller 17, and discharge roller 18 at the bottom of the document hopper are rotated in the direction of arrow _a3 , and the documents 15a in the document hopper 13 are drawn one by one between the pull-in roller 16 and the rubber pad 19.
Further, as shown in the document 15b, the conveyance roller 17
and the pinch roller 17p, and between the discharge roller 18 and the pinch roller 18p, and the original is transferred to the document stacker 20.
Stacked inside. The document 15b is irradiated with a fluorescent light 21 disposed between the conveyance roller 17 and the ejection roller 18, and the reflected light is reflected by the rightmost lens 2.
2, it is read by a photoelectric element 23 and transmitted. A detection switch 24 is located above the reading section.
is provided, reading is started by detecting the leading edge of the original 15b, and reading is completed after the trailing edge of the original 15b is detected and the original is fed a certain amount.

However, such a conventional configuration has a large external size and a large number of parts, which causes high costs. That is, in the receiving system, like a normal copying machine, there is a stacker 10 for storing recorded paper.
is arranged outside the outer wall 25 on the rear side of the apparatus, as indicated by the double chain line, so that the recording paper 2b accumulates outside the apparatus. For this purpose, a guide 8 for guiding the cut recording paper and transferring it onto the stacker 10, a discharge roller 9, a pinch roller 9p, a paper jam detection switch 12, etc. are required. Therefore, the present invention improves these parts to reduce the number of parts and downsize the device.

In the transmission system, it is normal that a pull-in roller 16 for pulling in a document, a conveyance roller 17, a discharge roller 18, and pinch rollers 17p and 18p for conveying and discharging the document are independent. The present invention reduces the number of conveyance rollers 17 and pinch rollers 17p by making the pull-in roller 16 also have the function of the conveyance roller 17, and also moves the pull-in roller 16 to the position of the conveyance roller 17, thereby increasing the height of the device. We are trying to reduce the size.

That is, the present invention has, as a basic configuration to achieve these objects, a roll paper for recording, and after receiving facsimile information and recording it on the recording paper between a recording head and a capstan roller, A facsimile device is equipped with a receiving system that cuts the document using a cutter, and a transmitting system that uses a pull-in roller that sucks the document to be sent to a reading unit to read and transmit the document, and the recording paper after receiving and recording is transferred to the capstan roller. The transmission document is transferred to a stacker section equipped with a cutter means, and the transmission document suction section is provided with a pressing means for pressing the transmission document against a drawing roller, and the transmission document is transferred to a reading section by the drawing roller. The transmission document is configured such that the transmitted document read by the user is held and discharged by a pair of discharging rollers.

Next, an embodiment of a facsimile device according to the present invention will be described. FIG. 2 shows an embodiment corresponding to FIG. 1, and the same parts as in FIG. 1 are given the same reference numerals. First, in the receiving system, the paper guide 8, ejection roller 9, pinch roller 9p, and detection switch 12 are eliminated. And Statsuka 2
6 is moved to the cutter section 5 position, and the paper introduction end 26e of the stacker 26 is placed below the movable cutter blade 7. As a result, the side wall 27 at the back of the device is disposed immediately outside the cutter portion 5, reducing the longitudinal dimension of the device. The paper introduction end 26e of the stacker 26 is located inside the side wall 27, and a portion of the stacker 26 is inserted into the main body of the apparatus, but since the amount thereof is small, the stacker 26 may be left set in the main body of the apparatus or left inside the apparatus. By removing it from the main body, the stacked recording sheets can be easily taken out from the stacker 26. Further, according to this configuration, since the discharge roller 9 and the pinch roller 9p are omitted, the power transmission means between the drive source and the drive source is also omitted. Note that the movable cutter blade 7 may be of a rotating type or a swing type, but if it is of a swing type, the recording paper can be stacked up to just below the movable cutter blade.

The transmission system includes a conveyance roller 17 and a pinch roller 17.
p is omitted. A pull-in roller 16' made of a rubber roller is moved to the position of the conveyance roller 17 in place of the conveyance roller 17, and a rubber pad 19' for pressing the document against the pull-in roller 16' is also moved downward correspondingly. The operation is the same as the conventional device shown in FIG.
When a document is detected, the pull-in roller 16' is started, and the document is sandwiched between the rubber pad 19' and transported one by one to the reading section. And manuscript 15
The leading edge of the paper b is guided by the paper guide 28 and transferred to the reading unit, and when the leading edge of the paper is detected by the detection switch 24 and further transferred by a certain amount, reading begins when the leading edge of the paper reaches the reading unit. When the leading edge of the paper is pinched between the ejection roller 18 and the pinch roller 18p, the pull-in roller 16' is separated from the drive source by the clutch, but the document 15b remains pinched between the pull-in roller 16' and the rubber pad 19'. , discharge roller 18 and pinch roller 1
When the original 15 is moved by pulling down the original 15b at step 8p, the pull-in roller 16' also rotates. Therefore, the original 15b is stretched tightly between the ejection roller 18, the pinch roller 15p, the pull-in roller 16', and the rubber pad 19', and reading is performed accurately.

As is clear from the above embodiments, according to the present invention, in the transmission system, the cutter portion 5 of the recording paper
By arranging the paper introduction end 26e of the stacker directly under the conventional recording paper ejection roller 9,
Paper feeding means such as the pinch roller 9p, paper guide 8, and detection switch 12 can be omitted, and by providing the side wall 27 at the back of the device near the cutter section 5, the device main body can be made smaller, and the stacker 26 can be Since a part of the stacker is inserted into the main body of the device, the entire device including the stacker can be further miniaturized. In addition, in the transmission system, the number of parts can be reduced by omitting the conveyance roller 17 and its pinch roller 17', and by moving the pull-in roller 16' and rubber pad 19' to the positions of the conventional conveyance roller 17 and pinch roller 17p. This makes it possible to reduce the size of the device body in the height direction.
