Further, the feed amount of the guide roller 17 is different depending on the size of the recording paper.

Next, the operation steps of the receiving apparatus of FIG. 2 will be described in detail. (B) In the transmission side device, the MPU control unit 1 of the transmission device shown in FIG. 1 determines through the panel control unit 7 that the operator has pressed the transmission button on the panel 8. Based on this, the MPU controller 1 activates the transmission controller 2. From the transmission control unit 2 through the modulation / demodulation unit 3 and the line, FIG.
The call signal is sent to the line control unit 14 of the receiving side device shown in FIG. Thereby, the line control unit 14 notifies the main computer 11 that there is a transmission from the transmission side device, and the main computer 11 controls the line size of the paper set in the recording paper loading device 12 by (C) described later. Part 1

The size is determined based on the recording paper size of the device, and the information indicating the reading width is notified to the receiving device. That is, the number of read pixels is determined as follows according to the size of the transmission document and the size of the recording paper of the receiving device.

(A) When the size of the transmission original is the same as the size of the received recording paper, the number of pixels of the size of the transmission original is sent out. (B) When the size of the transmission original is larger than the size of the reception recording paper, the image signal reduced in size is sent by the reading density adjusted by the size of the reception recording paper or the reduction by the lens in (g) described later.

(C) When the size of the transmission original is smaller than that of the receiving recording paper, the image signal of the transmission original size is transmitted. (D) If the sending side does not have a reduction function, the size of the read original document on the sending side is notified. According to the above (a), (b), and (c), the MPU control unit 1 determines the image signal size to be transmitted, and notifies the receiving side device via the line control unit 14.

(F) The line controller 14 of the receiving side device receives the information including the image signal size and notifies the main computer 11 of the information. The main computer 11 notifies the print control unit 16 of this size information, and specifies a predetermined amount of image signal received by the perforation creating unit 21, the electrostatic printer 19, and the guide roller 17 by the transmission side device. Control is performed so that recording can be performed with a large image signal size.

(G) The MPU control unit 1 of the transmission side device reads either the scale factor 5 determined in the step (e) under the control of the optical system 5 or the reduction unit 5'under the control of the electric system, or both. Is realized by reading the image information on the manuscript, and the image signal of the determined number of pixels is transmitted to the transmission control unit 2.
Encode with. When the encoded image signal is transmitted from the transmission device via the modulation / demodulation unit 3, the line control unit 14 of the reception side device receives it and supplies it to the decoding unit 15.

(H) The decoding unit 15 decodes the encoded image signal. At this time, if the sending device does not have a reduction function and the size information is supporting a paper larger than the receiving paper, the pixel signal is extracted at a predetermined cycle from the decoded data to obtain a predetermined number of bits. And supplies it to the print control unit 16. (I) The print control unit 16 causes the electrostatic printer 19 to divide the image signal into the number of image signals of the magnitude notified in the step (f), and sequentially supplies the image signals to the electrostatic printer 19. For example, if the electrostatic printer 19 has one line of latent image forming electrodes corresponding to the number of pixels of one line, one line of received and decoded data is sequentially scanned onto the electrodes. It is realized by giving.
