ABSTRACT:
A picture information input apparatus has a leading and trailing end detecting circuit for detecting the leading and trailing ends of a document to produce read out signals of "1" and "0". The leading and trailing end detecting circuit starts a first count by a document presence detecting signal of "0" from a detecting unit which detects the transfer of the document. When a hole of the document is smaller than an allowable hole diameter, it clears the counting. Only when the hole is larger than the allowable hole diameter, it starts a second count. After the second count ends, it produces a read out signal of "0" indicating that the trailing edge of the document is detected. A picture bus control circuit receives the read out signal of "1" to transmit a picture data signal to a picture transceiver, and receives the read out signal of "0" to stop the transmission of the picture data signal.
