Next, the operation of the block circuit will be described with reference to the flowchart of FIG.

First, in the standby state before transmission or reception, the big-up / separation roller 27 is not energized from the control unit 51 to the solenoid 36, and is always located on the document transport side. This state is step S1.

When a plurality of original sheets 26 are set on the original table 24 through the original insertion port 25, step S
2, the sensor A detects the presence of the original sheet 26, and the pickup / separation roller 27 is rotated by the drive instruction from the control unit 51 to the drive mechanism unit 54. As described above, the original sheet 26 is rotated by the pickup / separation roller 27. By doing so, the sheets are separated and conveyed. When the sensor A detects the absence of the original sheet 26 in step S2, it is determined in step S3 whether the original sheet 26 has been conveyed. When the sensor C detects the presence of the original sheet 26 in step S3, it is determined that the conveyance of the original sheet 26 is not completed, and the process returns to step S1. When the sensor C detects the absence of the original sheet 26 in step S3, it is determined that the transportation of the original sheet 26 is completed, and the process proceeds to step S4. In step S4, the receiving unit 52
