Abstract
A scanner unit changes a first wire included in a pair of wires in Low condition into High condition, sets another second wire in Low condition during the change, and identifies whether a CISM coupled with a resistor is or a CISM coupled with no resistor is by inputting a signal from the second wire afterward. Further, the controller changes the first wire in High condition into Low condition, sets the second wire in High condition during the change, and identifies the CISM by inputting a signal from the second wire. The scanner unit sets the second wire in condition before being changed while changing condition of the first wire so as to prevent an effect of a signal (crosstalk) caused when the condition of the first wire is changed more effectively.
