Abstract

PURPOSE:To increase the reliability of read-in, by performing read-in for the same information by giving a certain time shift and using the information only when the result of read-in is in agreement. CONSTITUTION:The information from the input media 1 is read in with the reader 2, and it is stored in the memory circuit 4, and the same information is read in 2 with a certain time shift, and it is inputted to the comparison circuit 5 together with the signal in the circuit 4. Further, only when the result of the read-in is in agreement, the information is used. Thus, the reliablility to read-in can be increased.
