している。A facsimile transmitter according to the present invention includes a first means for storing a voltage value obtained by performing a main scan on a white portion in advance for each document size, a second means for outputting size information of a set document, and a transmission means. The voltage value read by scanning the white portion of the leading edge of the document to be scanned is determined by the size information.
And a third means for outputting an alarm signal indicating a skew of the original to be transmitted when the voltage value read from the means is different.

斜行検出時には元のセット位置に戻す。The image sensor unit 1 outputs a binary signal obtained by reading the original in the main scanning direction using a CCD and an optical device. The signal processing unit 2 outputs digital image information obtained by encoding the binary signal from the image sensor unit 1. White data storage unit 3
Stores, via the white data input switching unit 4, the voltage value of the binary signal from the image sensor unit 1 obtained by scanning the white portion in advance for each document size (B4, A4, B5 plates). Skew detection unit 5
Compares the voltage value of the binary signal from the image sensor unit 1 that has read the white portion of the leading edge of the document to be transmitted with the voltage value stored in the white data storage unit 3 to determine the running state of the document and to The alarm signal 5a is output when it is running. The switching unit 7 switches the output from the image sensor unit 1 to the signal processing unit 2 or the skew detection unit 6 according to the signal from the control unit 5.
The traveling unit 8 moves the document loaded in the document insertion unit in the sub-scanning direction so that it can be read by the image sensor unit 1, and returns it to the original setting position when skew is detected.

戻し、原稿を再セットする。The control unit 6 discriminates the size of the document set in the document insertion unit and controls the traveling unit 8 to move the document to the reading position of the image sensor unit 1 based on the transmission operation (calling operation of the destination telephone number) information. Let Image sensor unit 1
Inputs the voltage value of the binary signal read by scanning the document in conjunction with the traveling unit 8 to the skew feeding detection unit 5 via the switching units 4 and 7. The skew feeding detection unit 5 compares the voltage value for each size of the document stored in the white data storage unit 3 with the voltage value from the image sensor unit 1, and a difference occurs between the voltage values of the two, and the document is skewed. If it is determined that the alarm signal is present, the alarm signal 5a is sent to the control unit 6. Under the control of the control unit 6, the traveling unit 8 returns the document to the document insertion port and resets the document.
