PURPOSE:To reduce the variation in line capacitance and reduce the variation in sensitivity by a method wherein a plurality of optoelectric transducers made of amorphous semiconductor are arranged on a glass substrate to form a line sensor and the respective transducers are connected to driving LSI's by wirings with uneven lengths and those wirings are covered with resin films. CONSTITUTION:A plurality of optoelectric transducers 10 made of blocking type amorphous semiconductor, which prevents external carriers from flowing into devices and allows internal carriers to flow out, are arranged in a line to form a copy reading line sensor. The respective transducers 10, denoted by 11a-11r, are alternately connected to a driving LSI 12a and a driving LSI 12b, provided on both sides of the transducers 10, by wirings 11 which also serve as lower leading out electrodes. As the lengths of the wirings 11 are uneven, variation in line capacitance is created. Therefore, films 20a and 20b of resin which has larger specific inductive capacitance than air such as polyimide are applied to the wirings 11 so as to cover the longer distance of the shorter wiring length part and the shorter distance of the longer wiring length part. |
