<P>PROBLEM TO BE SOLVED: To provide an electric apparatus capable of detecting a setting state of a plurality of devices by a more inexpensive and simple configuration. <P>SOLUTION: The electric apparatus has the plurality of devices 15a, 15b and 15c of the same kind or different kinds set detachably. The electric apparatus is configured to include a plurality of resistors Ra, Rb and Rc which are set at a body side, have different resistance values and change a mutual connection state in accordance with the setting state of each of the plurality of devices 15a, 15b and 15c, and a detecting means for detecting a combined resistance value of the resistors Ra, Rb and Rc in accordance with one or a plurality of the setting states of the plurality of devices 15a, 15b and 15c. <P>COPYRIGHT: (C)2004,JPO |
