Abstract:
1. A sensor unit actuating mechanism comprising: a frame disposed around an object to be measured; a sensor unit comprising a sensor for measuring a physical quantity from the object to be measured, the sensor unit being disposed inside the frame; a guide member configured to guide the sensor unit to move in an X direction linearly, the X direction being a direction from inside the frame to a measurement position; a spring member configured to expand or contract in a first Y direction, the spring member having one end fixed to the sensor unit and the other end fixed to the frame; and an actuator configured to expand or contract in a second Y direction, the actuator disposed so as to move the sensor unit when the actuator is energized to contract, the first and second Y directions being a direction having an angle of 45 to 135 degrees or −45 to −135 degrees relative to the X direction and non-parallel to each other, wherein the sensor unit is linearly moved from inside the frame to the measurement position in the X direction by energizing the actuator to contract against resilience of the spring.
