Abstract
An image reader applicable to a document or image reading section of a facsimile apparatus or the like and equipped with a line image sensor. Light-sensitive cells of the line image sensor are divided into blocks which in turn are sorted by the order of arrangement into a plurality of groups. The blocks in one group are switched from one to another while outputs of the other group are selected. The light-sensitive cells constituting the respective blocks are classified into a plurality of groups by the order of arrangement, so that the different groups are driven in parallel.
