Abstract
A reading apparatus having a photo-detecting element array constituted by a plurality of photo-detecting element blocks each constituted by a plurality of photo-detecting elements, and having switching elements for transferring charges generated in the photo-detecting elements block by block to an output circuit, in which the output circuit has wirings having no crossing portions and the outputs of the photo-detecting elements can be produced as time-series signals without requiring any external memory. In the reading apparatus, the switching elements are selected block by block of the photo-detecting element array, the blocks are commonly connected so that the respective orders of adjacent two of the blocks in the output circuit are opposite to each other, and an output of the output circuit is selected by two selection circuits synchronized with the selection of the switching elements, the two selection circuits respectively having selection orders which are opposite to each other, whereby the selection circuits are switched block by block of the photo-detecting element array to thereby obtain a time-series output.
