Abstract

PURPOSE:To make it possible to exactly select a reproduction image, by controlling the read part or the reproduction part by a detection signal, and selecting a prescribed bed area. CONSTITUTION:The effective part of a picture is selected by the guide plates 302, 304. The effective part of a picture in the subscanning direction is visibly displayed by the guide plate 304, and this effective width is detected by the detecting element 305. When an output of this element 305 is input to the gate circuit 311, for instance, when an output of the detecting element 305 is ''1'', the gate circuit 311 outputs a picture signal from the gate circuit 310, and when an output of the element 305 is ''0'', an output of the gate circuit 310 is controlled so that a picture signal from the gate circuit 310 is not output, and as a result, a picture signal which has scanned only the shaded part shown in the figure can be obtained.
