Abstract
A card interface or the like having compatibility is employed for connecting a communication module or the like for transmitting and/or receiving data. The communication module is changed so as to realize a variety of functions without enlargement of the size of the apparatus. The connection has compatibility so that a function module for adding and/or changing functions is employed in addition to the communication module. Therefore, the function can be improved without the cost rising.
