    • In a non-volatile memory are arranged a plurality of IC card storage units corresponding to a plurality of IC cards each storing therein an electronic money representing the value of currency in the form of electronic information. A command control unit executes concurrently commands imparted to the plurality of IC card storage units arranged in the non-volatile memory to logically implement a control function of the plurality of IC cards. In addition, upon a receipt of a single or a plurality of commands from a host apparatus (a money server), a communication control unit forms concurrently communication paths corresponding in numbers to the commands and associated with the command control unit to logically implement a function of communication with the plurality of IC card storage units.
    • 在非易失性存储器中布置有多个IC卡存储单元,其对应于多个IC卡,每个IC卡存储表示电子信息形式的货币值的电子货币。 命令控制单元同时执行赋予设置在非易失性存储器中的多个IC卡存储单元的命令,以逻辑地实现多个IC卡的控制功能。 此外,在从主机设备(货币服务器)接收到单个或多个命令时,通信控制单元同时形成与命令对应的通信路径并与命令控制单元相关联,以逻辑地实现功能 与多个IC卡存储单元进行通信。

    • The present invention relates to a device connection state recognizing method capable of recognizing a connection state of devices without addition of signal lines dedicated to detection. Thus, in the method according to this invention, a portion of or all of a plurality of data signal lines are connected through pull-up resistors to a high electric potential or connected through pull-down resistors to a low electric potential in accordance with the connection state of the devices, and a processing unit reads, as structure information data, a high electric potential state/low electric potential state generated by the pull-up resistor/pull-down resistor in the portion of or all the plurality of data signal lines to recognize the connection state of the devices on the basis of the read structure information data. This invention is applicable to a various types of processing units which are to be connected through a common data bus to a plurality of devices.
