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.
Claims9
An image reading apparatus, comprising:
- a frame configured to move in a reciprocating fashion;
- a light source held by the frame and configured to emit light so as to irradiate an image surface of an original;
- a photo-electronic converting element configured to receive light reflected by the image surface of the original and to convert the received light into an analog image signal;
- and
- a flexible plate configured to connect the light source to a voltage source not mounted on the frame for applying a driving voltage to the light source, said flexible plate including a first printed wire configured to apply a driving voltage to the light source, and including a second printed wire configured to establish a ground to the frame,
- wherein the driving voltage applied to the light source comprises a voltage having a pulse waveform.
An image reading apparatus, comprising:
- frame means for moving in a reciprocating fashion;
- light emitting means held by the frame means and for emitting light so as to irradiate an image surface of an original;
- photo-electronic converting means for receiving light reflected by the image surface of the original and for converting the received light into an analog image signal;
- and
- binding means for flexibly connecting the light emitting means to a voltage means not mounted on the frame means for applying a driving voltage, said binding means including a first printed wire for applying the driving voltage to the light emitting means, and including a second printed wire for establishing a ground to the frame means,
- wherein the driving voltage applied to the light emitting means comprises a voltage having a pulse waveform.
