Abstract
PURPOSE: To make it possible to shorten the transmission time and the recording time of picture signals by providing a mans, which recognizes the effective area on manuscript, and using output signals of this means.
CONSTITUTION: Manuscript 1 on manuscript stand 3 has the part on the main scanning position illuminated, and the direction of the reflection light is changed through light path 4 by mirrors 5 and 6, and the reflection light is reduced by condenser lense 7 and is focused on image pickup element 8. Element 8 performs the photoelectric conversion of the focused image of the main scanning position in manuscript 1, and manuscript reading which is subscanning is executed by moving the main scanning position. That is, subscanning is reciprocated to recognize the effective area, where information is distributed in a prescribed range of manuscript 1, by the output of photoelectric conversion element 8 at a subscanning time when the main scanning position is reciprocated. As a result, the transmission time and the recording time of picture signals can be shortened
