Abstract

An IC card adapted to be removably inserted into a slot of an IC card mountable device, including a card housing formed like a substantially rectangular card with an inside space defined therein, the card housing having a plurality of openings through a wall of the card housing; a printed wiring board accommodated in the card housing; and a plurality of electronic components mounted on the printed wiring board.

Claims

1. A card cooling tray removably insertable into a slot of a card mountable device in a condition where a card is held on said cooling tray, comprising:

a tray body removably insertable into said slot such that a first portion is present inside said slot and a second portion extends beyond an outer perimeter of said slot when said tray body is fully inserted, said tray body having an inside space extending from the first portion to the second portion, the first portion having a first opening for making communication between said inside space and a space inside of said card mountable device, the second portion having a second opening for making communication between said inside space and a space outside of said card mountable device; and

a fan mounted on the second portion of said tray body for generating an air flow between the space inside of said card mountable device and the space outside of said card mountable device through the inside space of said tray body.

2. An insertable device removably insertable into a slot of a card mountable device, comprising:

a body having a first part removably insertable into said slot and a second part positioned out of said slot when said body is fully inserted into said slot, said first part defining an air flowpath and an opening; and

a fan mounted on said second part of said body for generating air flow through the air flowpath,

wherein the air flowpath is formed so as to pass the air flow between the opening and said fan.

3. The insertable device according to claim 2, wherein the air flow passing through the air flowpath is directed toward outside of the card mountable device.

4. The insertable device according to claim 2 wherein said body is formed of a material having a high heat conductivity.

5. The insertable device according to claim 2 wherein the opening is formed at or adjacent a front end of said body.

6. An article of manufacture, comprising:

a body having a first part so configured and arranged to be removably insertable into a PCMCIA slot of a card mountable device and having a second part continuous with the first part and extending beyond an outer wall surface of the card mountable device upon full insertion of the first part into the PCMCIA slot, said first part defining a first opening which connects a first inside space defined by the first part with the PCMCIA slot and said second part defining a second opening which connects a second inside space defined by the second part with ambient air outside of the card mountable device such that the first space and the second space are in fluid connection; and

a fan mounted on said second part of said body to generate an air flow through the PCMCIA slot through the first inside space, the second inside space and through the second opening to the ambient air.

7. An insertable device removably insertable into a slot of an IC card mountable device, said insertable device comprising:

a body fully insertable into the slot such that the rear end portion extends beyond an outer wall surface of a housing of the card mountable device when said body is fully inserted into the slot, said body defining an inside space which opens within the housing through a first opening and which opens to ambient air through a second opening; and

a fan mounted to said body on the rear end portion thereof to generate air flow between the inside space of the housing and ambient air through the second opening.

8. The insertable device according to claim 7, wherein the air flow passing between the inside space of said body and ambient air is directed away from the interior space.

9. The insertable device according to claim 7, wherein said body is formed of a material having a high heat conductivity, and which is so configured and arranged to be removably received within a PCMCIA slot.

10. The insertable device according to claim 7, wherein the inside space opens to the housing through a plurality of openings.

11. The insertable device according to claim 10, wherein said plurality of openings are formed in a row.
