PURPOSE:To stably record a large number of analogue input signals at a high speed, by constituting the title apparatus of three common blocks of measurement, recording and the others respectively controlled by three microprocessors. CONSTITUTION:The first microprocessor muP1 performs predetermined operation to the analogue input signals converted by A/D converters AD1, AD2 on the basis of the measuring condition data stored in the third microprocessor muP3 and the measuring command therefrom and stores the operation result in the common area with the third microprocessor muP3 of a RAM 1. After the operation of one measuring cycle is finished, the microprocessor muP3 stores the operation data in the common area of a RAM 2 along with a recording command. The second microprocessor muP2 controls a motor and a solenoid on the basis of the data stored in RAM 2 to obtain desired dot recording. Further, the microprocessor muP3 performs the remote input control of a display device DP, a keyboard KB and an internal output relay RL. The operations of the microprocessors muP1-muP3 are performed in parallel.
