Abstract
A power supply controlling function is provided in a controlling portion. The power supply controlling function defines a first pressure sensor, a second pressure sensor, a third pressure sensor, and an oscillation detecting sensor as sensors to which power may be supplied, and turns switches that are provided in the supply circuits of the power supply to the individual sensors to which power may be supplied ON and OFF so that a plurality of these sensors to which power may be supplied does not operate simultaneously.
