CARD TYPE ELECTRONIC DEVICE SYSTEM AND CARD TYPE ELECTRONIC DEVICE

摘要

It is possible to realize a card type electronic device system in which a combination of a CF card and a dedicated adapter mounted on a PC card slot can realize the function and performance equivalent to a PC card while a single CF card mounted on a CF card slot can realize the function and performance in accordance with the maximum supply current standard value of the CF card slot. After an operation start, the CF card recognizes the dedicated adapter according to a predetermined recognition procedure (steps S101, S102). If no dedicated adapter is recognized, a predetermined operation condition matched with the maximum supply current standard value of the CF card slot is selected (step S104). On the other hand, if a dedicated adapter is recognized, a predetermined operation condition matched with the maximum supply current standard value of the PC card slot is selected (step S103). The dedicated adapter has self-identification means matched with the predetermined recognition procedure.
