Abstract
An image reading apparatus having a partition module between an image sensor module and a heat source (e.g., a laser-beam printer) includes a partition module disposed between the image sensor module and the heat source. The partition module has two walls with a gap therebetween for thermally insulating the image reading module from the heat source. Preferably, the partition module has an air intake port, and an air exhaust port, and an fan for circulating cooling air.
Claims29
An image reading apparatus comprising:
- an image reading module;
- a heat source disposed adjacent said image reading module;
- and
- a partition module disposed between said image reading module and said heat source and having at least two walls with a gap therebetween for thermally insulating said image reading module from said heat source.
An image reading apparatus comprising:
- an image reading module;
- a heat source disposed adjacent said image reading module;
- a partition module disposed between said image reading module and said heat source and having at least two walls with a gap therebetween for thermally insulating said image reading module from said heat source;
- a heat insulating layer disposed on the heat source side of the partition module;
- and
- cooling means for cooling the gap, wherein said cooling means comprises a structure for forcibly exchanging air inside the gap, said structure comprising a fan disposed adjacent said image reading module, and an air exhaust port is disposed at a side of said partition module opposite said image reading module.
