Abstract
In a photoelectric conversion device including peripheral ICs, the peripheral ICs are in thermal contact with a substrate having photoelectric conversion elements and a chassis, which covers the peripheral ICs and has high thermal conductivity, via a thermal conductive member, so as to eliminate adverse influences of heat produced by the peripheral ICs such as a low S/N ratio.
Claims23
A photoelectric conversion device comprising:
- photoelectric conversion means for receiving light that carries information and photoelectrically converting the light into an electrical signal;
- an integrated circuit element for processing the electrical signal converted by said photoelectric conversion means;
- and
- a housing which accomodates therein said photoelectric conversion element and said integrated circuit element,
- wherein a thermal conductive member for thermally connecting said integrated circuit element and said housing is interposed between said integrated circuit element and said housing.
A photoelectric conversion device comprising at least:
- a phosphor for absorbing radiation and emitting light;
- photoelectric conversion means for receiving the light emitted by said phosphor and photoelectrically converting the light into an electrical signal;
- an IC for processing the electrical signal converted by said photoelectric conversion means;
- a metal chassis for integrally holding the respective members and transmitting the radiation;
- and
- a member with a high thermal conductivity, which is interposed between at least a portion of said IC and said chassis and/or said radiation absorbing member.
