PICTURE PROCESSING UNIT

摘要

PURPOSE:To surely sense a reflecting plate or a lever and to prevent mis- detection by setting an output value of an image sensor or an output value close thereto being a displacement of the lever with respect to the reflecting plate as a threshold value. CONSTITUTION:Only a range designated by an image cutter lever 20 of a picture data read by an image reader section 40 is read by a picture memory section 50. Then the picture data of the memory section 50 is outputted to a printer section 60. The image cutter lever 20 is slid to place the reflecting plate to a prescribed position toward this side of a original glass. The output of the image reader section 40 is detected by using an output value to the reflecting plate or an output value close thereto as a threshold value thereby detecting the position of the image cutter lever 20 or the reflecting plate.
