Abstract
An electronic apparatus is provided. The electronic apparatus includes a case body including a single crystal body in at least a portion thereof, the single crystal body containing alumina (Al2O3) as a main component; a plurality of information processing devices in the case body; and a thermally conductive portion that thermally connects at least one of the information processing devices to the single crystal body.
Claims10
An electronic apparatus comprising:
- a case body including a light-transmissive cover plate;
- a circuit board including a peripheral portion;
- a plurality of information processing devices in the case body, at least one of the information processing devices located on the peripheral portion of the circuit board;
- an image display device in the case body, the image display device including an image display surface;
- and
- a thermally conductive portion in the case body,
- wherein
- the light-transmissive cover plate is a single crystal plate containing alumina (Al2O3) as a main component,
- the light-transmissive cover plate includes
- a first principal surface that faces the image display surface and a second principal surface opposite to the first principal surface,
- the light-transmissive cover plate further includes:
- a display portion on which an image of the image display surface is displayed;
- and
- a peripheral edge portion that surrounds the display portion,
- the thermally conductive portion is connected to at least a part of the peripheral edge portion,
- the thermally conductive portion is not connected to the display portion, and
- the thermally conductive portion is located between and directly connects the at least one of the information processing devices located on the peripheral portion of the circuit board and the peripheral portion of the light-transmissive cover plate.

An electronic apparatus comprising:
- a case body comprising a cover plate, the cover plate consisting of a single crystal plate and being light transmissive;
- a circuit board including a peripheral portion;
- at least one processor disposed in the case body;
- an image display device disposed in the case body, and comprising an image display surface;
- and
- a thermally conductive member comprising:
- a first member disposed in the case body;
- a second member disposed in the case body, and connected to the first member;
- wherein the cover plate includes a surface, the surface including:
- a first region that faces the image display surface, and that is connected neither to the first member nor the second member and
- a second region that surrounds the first region, that does not face the image display surface, and that is connected to the first member while the second member is connected to the at least one processor, and
- the thermally conductive portion is located between and directly connects the at least one processor located on the peripheral portion of the circuit board and the peripheral portion of the light-transmissive cover plate,
- wherein the thermally conductive portion includes a high-thermal-conductivity body containing a single crystal of alumina (Al2O3) as the main component.
