PURPOSE: To directly process a stored, integrated value in a integrated data processor and to improve the reliability of integrated data by providing a counting integrating device having a nonvolatile memory incorporated with a counter counting the number of pulses from a pulse generation means, and reading the integrated value stored in the device by means of a read means.

CONSTITUTION: Pulse signals corresponding to the quantity of rotation detected in a detector for quantity of rotation 2, which is equipped in the axis of rotation 1 in the integrated data processor, are inputted to a supervisory board 10 and are supplied to mechanical pulse counters 4a-4h for eight digits. The outputs of the counters 4a-4h are supplied to the data processor 30 through BCD output buffers 8a∼8h. The processor 30 receives BCD data in an interface board 23, and reads the counting values in correspondence with respective digits by digital inputs in accordance with the instruction of CPU 11 connected to a system bus 21. The data is once stored in a prescribed RAM area in the prescribed position of a memory board 14, and a line printer control board 12 reads it according to need.
