Abstract

PURPOSE: To enable to read in the effective input information correctly, by taking the input information as correctly inputted information, when the input information is read in after the input unit reads in the absence of input information two or more times.
CONSTITUTION: The input operation section 2 provides the input section 2a such as key switch, and when the key switch is depressed with the input operation, the signal is delivered to the input read-in section 4. Further, the read-in section 4 reads in whether or not the key switch produces the information in response to the timing pulse produced at the clock set 3, and the discrimination circuit 5 discriminates whether or not the effective information is produced. In this case, when the read-in period of the input unit 2a is taken as the minimum input operation time or less of the input unit 2a. If the input information is obtained after reading in the absence of input information twice or more, this input information is taken as correctly inputted information. Thus, effective input information can correctly be read in.
