Abstract
A card-type storage device and a slot device, which are capable of preventing lowering of the reliability due to repeated insertion and removal of the storage device. A card medium includes card thermal contacts each having a contact surface which intersects with a thickness direction of the card medium. A first card upper guide surface restricts the position of the card medium in the thickness direction to a first position. An escape portion restricts the position of the card medium in the thickness direction to a different position from the first position. A second card upper guide surface links the first card upper guide surface and the escape portion.

A card-type storage device comprising:
- a plurality of electrical contacts configured to electrically connect to a slot device of an electronic apparatus;
- and
- at least one thermal contact configured to thermally connect to the electronic apparatus,
- wherein the card-type storage device is inserted into and removed from the slot device,
- wherein the plurality of electrical contacts and the at least one thermal contact are disposed on an end of the card-type storage device in a direction of the inserting to the slot device,
- wherein the plurality of electrical contacts includes a first electrical contact for power supply and a second electrical contact for communication between the card-type storage device and the electronic apparatus,
- wherein the at least one thermal contact is different from the first electrical contact and the second electrical contact,
- wherein the plurality of electrical contacts and the at least one thermal contact are arranged in a line in a first direction orthogonal to the direction of inserting to the slot device and a thickness direction of the card-type storage device,
- wherein the at least one thermal contact is disposed farther than the first electrical contact and the second electrical contact with respect to a center of the first direction of the card-type storage device, and
- wherein the at least one thermal contact is disposed so that a distance between the at least one thermal contact and the first electrical contact is shorter than a distance between the at least one thermal contact and the second electrical contact.
A slot device into which and from which a card-type storage device is inserted and removed, the slot device comprising:
- a plurality of electrical contacts configured to electrically connect to the card-type storage device;
- and
- at least one thermal contact configured to thermally connect to the card-type storage device,
- wherein, in a state where the card-type device is inserted into the slot device, the plurality of electrical contacts and the at least one thermal contact are arranged in a line in a first direction orthogonal to a thickness direction of the card-type storage device and in a direction of inserting of the card-type storage device into the slot device,
- wherein the plurality of electrical contacts includes a first electrical contact for power supply and a second electrical contact for communication between the card-type storage device and the slot device, and
- wherein the at least one thermal contact is a contact different from the first electrical contact and the second electrical contact, and disposed so that a distance between the at least one thermal contact and the first electrical contact is shorter than a distance between the at least one thermal contact and the second electrical contact.
