PURPOSE:To inexpensively and easily constitute a device by installing switch modules and using the other control signal lines in common and suppressing the increase of the number of control signal lines to handle plural information cards. CONSTITUTION:A card device consists of an information processor consisting of a power supply module 4, a clock supply module 5, a reset supply module, an input/output interface module 7, and switch modules 8-10 connected to modules 5, 6, 7 respectively and two or more information cards 1 and 2 connected to the information processor. One of plural information cards 1 and 2 is selected by switch modules 8-10 to input and output information. Thus, the card device handling plural information cards is inexpensively and easily constituted because the increase rate of the number of control terminals is reduced. |
