Patent ID: 7123481

Claim:
An electronic device comprising: a circuit board with an electronic circuit; a heat conducting means to conduct heat generated in the electronic circuit; an electronic element to be used under an ambient temperature lower than a temperature of the heat conducting means heated by heat generated in the electronic circuit; a support means to support the circuit board, the heat conducting means, and the electronic element; and an optical disk as an information recording medium, wherein the support means is positioned between the heat conducting means and the electronic element so that a first plane of projection of the heat conducting means on the support means and a second plane of projection of the electronic element on the support means do not overlap with each other, wherein the electronic element is a laser, and wherein the optical disk, the heat conducting means and the laser are so positioned that a third plane of projection of the heat conducting means on a plane parallel to the optical disk and a fourth plane of projection of the laser on the plane parallel to the optical disk do not overlap with each other.
