In addition, the perforation creating section 21 is configured to create perforations in the length direction of the roll paper, so that the width of the recording paper after being cut can be adjusted, and the feed amount of the guide roller 17 can be adjusted to They vary depending on size.

Next, the operational steps of the receiving apparatus shown in FIG. 2 will be described in detail.

(b) MPU control unit 1 of the transmitter shown in Figure 1
However, it is determined via the panel control unit 7 that the transmit button has been pressed by the operator on the panel 8.
Based on this, from the MPU control unit 1 to the transmission control unit 2
Start. The transmission control unit 2 is connected to the modem unit 3 and then to the line control unit 14 shown in FIG. 2 via a line.
A call signal is sent to As a result, the line control unit 14 notifies the main computer 11 that there is a document to be sent, and the main computer 11 checks the size of the paper set in the recording paper loading device 12 by transmitting the line as described in (c) below. It acts to notify the control unit 14.

(b) On the other hand, in the recording paper loading device 12, a sensor 12c (micro switch) provided under the pulley 12a that holds the recording paper detects the size of the receiving recording paper 12b, and for example, when the receiving device is powered on, Paper width information is set in the size discrimination register 13 at the time of insertion.

(c) The main computer 11 reads the contents of the size determination register 13 according to the specification in step (a) above, and determines whether this is A4 paper width, B4 paper width, B5 paper width, etc. If the width is less than the B4 paper width, this is notified to the line control unit 14. Also B4
If the paper width is greater than or equal to the paper width, the line control unit 14 is notified that signals of originals of all paper widths can be received.

(d) The line control unit 14 notifies the transmitter of this size information via the line.

(e) In the MPU control unit 1 (see Figure 1),
Using a table memory (not shown), determines the reading width of the transmitted original according to the size information of the recording paper based on the size of the original to be transmitted and the receiving side's recording paper size, and receives information indicating this reading width. Notify the device. In other words, the size of the original to be sent,
The number of pixels to be read is determined as follows according to the recording paper size on the receiving side.

(a) If the transmitted original size and the received recording paper size are the same, the number of pixels of the transmitted original size is sent.

(b) If the size of the transmitted document is larger than the received recording paper, transmit an image signal that has been reduced in size by adjusting the reading density to the received recording paper size or by reducing it with a lens as described in (g) below.

(c) If the size of the transmitted original is smaller than the received recording paper, an image signal of the size of the transmitted original is sent.

(d) If the sending side does not have a reduction function, notify the sending side of the size of the original to be read.

According to (a), (b), and (c) above, the MPU control unit 1 determines the image signal size to be transmitted, and notifies the receiving side via the line control unit 14.

(f) The line control unit 14 on the receiving side receives information including the image signal size and notifies the main computer 11 of the information. The main computer 11 notifies this size information to the print control section 16, and sends a predetermined amount of image signal received by the perforation creation section 21, the electrostatic printer 19, and the guide roller 17 to the size specified by the sending side. control so that it can be recorded at the same image signal size.

(g) The MPU control unit 1 realizes the scale ratio determined in step (e) above by using either or both of the reading unit 5 under control of the optical system or the reduction unit 5' under control of the electrical system. , the image information on the document is read, and the transmission control unit 2 encodes the image signal of the determined number of pixels at the reduced scale. When the encoded image signal is sent out from the transmitting device via the modulation/demodulation section 3, the line control section 14 on the receiving side receives it and supplies it to the decoding section 15.

(H) The decoding unit 15 decodes the encoded image signal. At this time, if the sending side does not have a reduction function and the size information indicates a paper larger than the receiving side paper, from the decoded data, at a predetermined period,
The pixel signal is extracted, converted into a predetermined number of bits, and supplied to the print control section 16.

(l) The print control unit 16 sequentially supplies image signals to the electrostatic printer 19 by dividing the image signals into the number of image signals of the size notified in step (f) above. For example, if the electrostatic printer 19 has one line of latent image forming electrodes corresponding to the number of pixels for one line, one line of received and decoded data is sequentially scanned onto the electrodes. This is achieved by giving
