Abstract
An adapter apparatus has a function of determining the type of a memory card, by communicating with the memory card at plural communication speeds and determining whether or not there is a response therefrom. A communication speed setting unit has a function of setting plural communication speeds for communication with the memory card, and a response determining unit determines whether or not there is a response to a type determination signal. A type determining unit determines the type of the memory card based on the communication speed set by the communication speed setting unit and whether or not there is a response to the type determination signal sent at the communication speed.
