Claims (1)
する為のサイズ検出機溝に於いて、受信時に前記
記録紙を蛍光灯により照射し、前記記録紙からの
反射光を原稿読取り用ＣＣＤセンサにより検出し
、前記ＣＣＤ出力を利用して記録紙のサイズを検
出することを特徴とした記録紙サイズ検出機構。 In the size detector groove for determining the size of the recording paper (A4, B4, letter), the recording paper is illuminated with a fluorescent lamp at the time of reception, and the reflected light from the recording paper is detected by a CCD sensor for reading the document. A recording paper size detection mechanism characterized in that the size of recording paper is detected using the CCD output.
