Title: Cover for card insertion slot
Inventor: KANEKO SABURO
IPC: G06K13/06
Filed: 1994-05-30
Abstract: PURPOSE:To enable a card insertion slot to be protected against dust and water, to facilitate the insertion and extraction of a card, and to make a user feel insertion and extraction light by providing a slanting surface for insertion guidance to the front end part of the abutting surfaces of both guides and a slanting surface for card discharge guidance to the rear end part. CONSTITUTION:In the normal state wherein a card C is not inserted, since a slide guide 10 abuts on a fixed guide 9 without any gap, the card insertion slot 3 of a card reader 1 is closed tightly. There is no possibility that a drop of water or dust enters the card insertion slot 3, and none of the sensor, etc., in the card reader 1 deteriorates. When the card C is pressed lightly against the slanting surface 12 for card insertion guidance, a slide guide 10 moves to open the card insertion slot 3 and the card C is inserted into the card insertion slot of the card reader 1 as it is. When the card C is drawn out, the slide guide 10 comes into tight contact with the fixed guide 9 and is put back into the normal state. Consequently, the resistance of the insertion and extraction of the card is small and even when the card reader is used for a long period, neither a drop of water nor dust enters the reader.

In such a constitution, when AC power is supplied from an AC power source 25, a current flows between the first and second conductive core shafts 14 and 15 through the elastic heating element 13 which directly generates heat. Since the elastic heating element 13 directly generates heat in this manner, time required for the rising of the temperature of the surface of the thermal fixing roller 11 to the temperature suitable for fixing is comparatively shorten and the thermal responsiveness can be improved. Moreover, heat generating efficiency with respect to the supplied power is excellent and the power can be saved.
