Abstract
An image reading apparatus includes a frame, a light source, a photo-electronic converting element, and a flexible plate. The frame is activated for a reciprocating movement. The light source emits light to irradiate an image surface of an original and is held by the frame. The photo-electronic converting element receives the light emitted by the light source and which is reflected by the image surface of the original. In addition, the photo-electronic converting element converts the light to an analog image signal. The flexible plate includes a first printed wire for applying a driving voltage to the light source, and a second printed wire for establishing a ground to the frame.
