Title:
光電変換素子、画像読取装置及び画像形成装置
Document Type and Number:
Japanese Patent JP6612492
Kind Code:
B2
Abstract:
A photoelectric conversion element includes a light receiving element, a buffer unit, a current control circuit, and an elimination circuit. The light receiving element generates electrical charge according to an amount of light received. The buffer unit buffers and outputs a voltage signal according to the electrical charge generated by the light receiving element. When the buffer unit outputs the voltage signal, the current control circuit controls electric current flowing through the buffer unit so as to be a predetermined amount of electric current. The elimination circuit eliminates high-frequency components in a band equal to or higher than a predetermined band from the voltage signal output from the buffer unit.
