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 formed of a substantially rectangular thin plate so that said card is kept in close contact with said tray body, a dimension of said tray body in a direction of insertion of said cooling tray into said slot being set so that said tray body has a first portion present inside said slot and a second portion projecting outward from said slot when said cooling tray is fully inserted in said slot, said second portion of said tray body being formed with a plurality of projections and recesses;

a holding member formed integrally with said tray body, for removably holding said card; and

a fan mounted on said plurality of projections and recesses of said second portion of said tray body for generating an air flow in the vicinity of said second portion.

2. A card cooling tray removably insertable into a card mountable device to cool an IC card, said cooling tray comprising:

a tray body;

a first portion removably connectable into a card mountable device;

a second portion having projections and a fan mounted on upper ends of said projections such that air flows between said fan and said projections, said second portion projecting outward of the mountable device when connected thereto; and

a holding member mounted on said tray body to hold a card in close contact with said tray body.

3. The card cooling tray according to claim 2, wherein said holding member has an L-shape.
