PURPOSE:To simplify a device and to facilitate data analysis by outputting data from the prescribed area in a shared memory to a control part through a printed circuit board installed in the idle slot of a common bus. CONSTITUTION:The printed circuit board 2 is installed in the idle slot of the common bus 9 of an arithmetic control part 1. The printed circuit board 2 is composed of a data input part 13 inputting data from the prescribed area in the shared memory 7 of the arithmetic control part 1 according to an instruction from the control part 3, an interface 14 exchanging signals between the control part 3 and itself and an internal memory 15 temporarily holding the data from the shared memory 7. The control part 3 supplies the data from the printed circuit board 2 to an output part 4.
