<P>PROBLEM TO BE SOLVED: To provide a controller in which the resistance can be altered easily without replacing a resistor even when the resistance pulling up or pulling down the input terminal of a detection signal is required to be altered. <P>SOLUTION: The controller is provided with a detection signal from an exclusive or shared detector 8 at an input terminal 30 which is pulled up or pulled down through a first resistor R1, and performs drive control of an electric apparatus (not shown) based on the detection signal thus provided. The controller comprises one or a plurality of second resistors R2 for pulling up or down the input terminal 30, one or a plurality of switching elements Tr1 for bringing the second resistor R2 into conductive state or nonconductive state, and means 28 and 29 for setting the switching elements Tr1 on/off by receiving external setting. <P>COPYRIGHT: (C)2007,JPO&INPIT |
