【発明の名称】複数の電圧のためのICカード用本体装置
Document Type and Number:
Japanese Patent JP2839477
Kind Code:
B2
Abstract:
An electronic device has a host with a card-receiving slot, and can receive and operate with both low voltage (3 volts) and high voltage (5 volts) IC (integrated circuit) cards. The inner end of the slot has a voltage-discriminating first side, and has a switch (82, FIG. 5) with an actuator (80) lying at a location that is occupied by a discrimination key portion (69) that is present in a low voltage card but not a high voltage card. The electronic device has both lower and higher voltage circuits (124, 130) for energizing lower and higher voltage cards, and the type of card sensed by the switch determines which circuit is connected to contacts at the inner end of the slot.
