Abstract

PURPOSE:To enable the signal processing without crosstalk and to increase the productivity, by the construction that the illumination light of light source is not irradiated to the photosensor unit of the same arrangement order of the photosensor block adjacent through the provision of light shield body. CONSTITUTION:The light source 201 of LED constitution and the light shield body 202 formed with black resin so that the surrounding can be covered, are provided, the reflected light from the original surface 203 is incident to the photosensor 205 provided on the substrate, and the information on the original 203 is read in. Further, the sensor section 205 has photosensor blocks B-1, B-2 consisting of two photosensor units u-11, u-12, u-21, and u-22 for a given number. Further, the light source 201 is arranged in 4mm. pitch for the number corresponding to the unit (u) for sequential lighting. Further, when the distance l0 from the original reflection surface to the light source 201, the distance l2 to the photo sensing surface of the sensor 205, and the distance l1 to the end of the shield body 202, are specified to a given size, the spreading distance l3 on the sensor photo reception surface is 4mm. or less and the light does not reach the unit u-21 of the block B-2 adjacent and no duplicated storage of signal is caused even with common connection.
