<p>PROBLEM TO BE SOLVED: To provide a control part, whose performance is higher than that of an extended unit mounting device at an extended unit side, and to control the extended unit mounting device side by the control part at the extended unit side. SOLUTION: An extended unit 1 is provided with a CPU 102, whose processing capabilities are higher than those of a card 2 to be mounted on an extended unit 1, and the CPU 102 detects connection with the card 2 by a power source control part 106, and thereby controls the card 2 with a CPU 202 set in the card 2. In the card 2, a transparent tablet 212 is arranged on a display part 211, and the inputting operation of the tablet 212 is controlled by the CPU 102 of the extended unit 1. That is, a program related with the display of an application is set in an ROM 203 of the card 2, and a program related with an input and edition using the tablet 212 is set in an ROM 103 of the extended unit 1.</p> |
