Abstract

PURPOSE:To make the buffer or the like consisting of plural inverters unnecessary to facilitate making the device small-size, by using a monostable multivibrator to delay the output signal of a state change detecting circuit. CONSTITUTION:Contact information A from a data terminal is inputted to state change detecting circuits 5 and 6 and a selector 7 through a filter 2; and if a state change is detected by a state change detecting circuit 2, the state change detection signal is inputted as an interrupt signal to a data processing device 15 by a detection signal G, and the data processing device 15 reads contact information from the selector 7 by this state change detection signal. The output signal of the state change detecting circuit 5 in this state change detecting circuit is delayed by a monostable multivibrator 17.
