Abstract
A card-type electronic device capable of suppressing a rise in the temperature of signal lines for high-speed communication requiring impedance control while ensuring sufficient thermal connection and electrical connection. A connector is fixed to a substrate on which electronic components that generate heat are mounted, and includes electrical contacts electrically connected to an external apparatus and a thermal contact thermally connected to the external apparatus. A cutout is formed in the substrate between a portion to which the thermal contact is fixed and a portion to which the electrical contacts are fixed.

A card-type electronic device comprising:
- a substrate on which electronic components that generate heat are mounted;
- and
- a connector fixed to the substrate, the connector including electrical contacts electrically connected to an external apparatus and a thermal contact thermally connected to the external apparatus,
- wherein the substrate has a cutout formed therein at a location between a portion to which the thermal contact is fixed and a portion to which the electrical contacts are fixed.
A slot into which and from which a card-type electronic device is inserted and removed, the card-type electronic device including a substrate on which electronic components that generate heat are mounted, and a connector fixed to the substrate, the connector including electrical contacts electrically connected to an external apparatus and a thermal contact thermally connected to the external apparatus, wherein the substrate has a cutout formed therein at a location between a portion to which the thermal contact is fixed and a portion to which the electrical contacts are fixed,
- the slot comprising:
- a slot base including electrical contacts and a thermal contact connected to the electrical contacts and the thermal contact of the card-type electronic device, respectively;
- and
- a substrate to which the slot base is fixed,
- wherein the thermal contact of the slot base and the thermal contact of the card-type electronic device are brought into surface contact with each other, in a state in which the card-type electronic device is inserted into the slot.
An electronic apparatus comprising:
- a card-type electronic device, the card-type electronic device including a substrate on which electronic components that generate heat are mounted, and a connector fixed to the substrate, the connector including electrical contacts electrically connected to an external apparatus and a thermal contact thermally connected to the external apparatus, wherein the substrate has a cutout formed therein at a location between a portion to which the thermal contact is fixed and a portion to which the electrical contacts are fixed;
- and
- a slot into which and from which the card-type electronic device is inserted and removed;
- and
- a control unit configured to control communication between the electronic apparatus and the card-type electronic device mounted in the slot.
