PURPOSE:To improve the reliability of data inputted to a computer, by executing collation and verification for parity and coincidence of respective contents of plural registers, where data of a transmission device are stored, and by checking verification results together with data in a verifying circuit. CONSTITUTION:Data D and a ready signal R from an information transmission device 1 are input to a data verifying device 2, and data D is stored in registers 5-1-5-3 through gates 4-1-4-3. The signal R is applied to a gate 6, and the pulse P from a pulse generator 7 is applied to a counter 8, and stored data is input to a verifying circuit 11 and a driver 13 by outputs 8a-8c of the counter 8. The output 8d of the counter 8 is applied to a monitor circuit 10 to count pulses P, and the output 8d is checked on a basis of the signal RT of the gate 6; and if it is different from a prescribed value, the abnormality signal AB indicating that data D is abnormal is applied to the driver 13. The signal from the circut 11 is applied to the driver 13, and thus, the reliability of data inputted to the computer is improved. |
