Abstract
An image reading unit includes an image sensor for converting light from a document into an electric signal, and a circuit board provided with the image sensor on one side. In the image reading unit, a heat dissipating member for controlling a temperature of the image sensor is attached to one side of the circuit board, and a shield member for reducing a noise is provided on the other side of the circuit board. The heat dissipating member and the shield member are connected by a heat conductive member. Also, the heat dissipating member is interposed between the image sensor and the circuit board.
Claims9
An image reading unit for reading an image on a document, comprising:
- a circuit board,
- an image sensor mounted on one side of the cicuit board for receiving light from the document and converting the same into an electric signal,
- a heat dissipating member disposed on said one side of the circuit board for dissipating heat of the image sensor,
- a shield member disposed on the other side of the circuit board for reducing a noise relative to at least one of the image sensor and the circuit board, and
- a heat conductive member situated between the heat dissipating member and the shield member to transfer the heat from the heat dissipating member to the shield member.
