Abstract
An image scanning apparatus includes an image pickup device, a substrate connected to a terminal of the image pickup device, a heat radiation plate which is disposed between the image pickup device and the substrate and one surface of which contacts the image pickup device, and an insulating sheet which is sandwiched between the heat radiation plate and the substrate, respective surfaces of which contact the heat radiation plate and the substrate, and which electrically insulates the heat radiation plate from an electronic component on the substrate.
Claims18
An image scanning apparatus comprising:
- an image pickup device;
- a substrate connected to a terminal of the image pickup device;
- a heat radiation plate disposed between the image pickup device and the substrate, a surface of the heat radiation plate contacting the image pickup device;
- and
- an insulating sheet sandwiched between the heat radiation plate and the substrate, respective surfaces of the insulating sheet contacting the heat radiation plate and the substrate, the insulating sheet electrically insulating the heat radiation plate from an electronic component on the substrate,
- wherein each of the heat radiation plate and the insulating sheet includes a hole through which the terminal of the image pickup device passes, and an inner wall of the hole does not contact a pin side wall of the terminal.
An image forming apparatus comprising:
- an image pickup device;
- a substrate connected to a terminal of the image pickup device;
- a heat radiation plate disposed between the image pickup device and the substrate, a surface of the heat radiation plate contacting the image pickup device;
- and
- an insulating sheet sandwiched between the heat radiation plate and the substrate, respective surfaces of the insulating sheet contacting the heat radiation plate and the substrate, the insulating sheet electrically insulating the heat radiation plate from an electronic component on the substrate,
- wherein each of the heat radiation plate and the insulating sheet includes a hole through which the terminal of the image pickup device passes, and an inner wall of the hole does not contact a pin side wall of the terminal.
