PROBLEM TO BE SOLVED: To acquire information from a sensor accurately while saving energy by controlling not only power supply to a sensor but also power supply to a sensor signal transmission circuit. SOLUTION: A timing control means 202 generates and delivers a sensor signal transmission circuit power supply control signal and a data take-in pulse. A power supply control means 203 receives the sensor signal transmission circuit power supply control signal and supplies power to a sensor signal transmission circuit 205 and a sensor group 105 (arrow is omitted). A data take-in means 206 takes in the sensor output from the sensor signal transmission circuit 205 by the data take-in pulse from the timing control means 202 and stores the sensor output which is read out by a controller 201 periodically or nonperiodically.
