Abstract:
1. An apparatus for inspecting a sensor module including at least one held sensor in a housing having a plurality of outer surfaces, the held sensor detecting acceleration in a direction of a first reference axis or angular velocity around the first reference axis, the apparatus comprising: a holding unit that has an apparatus-side reference surface and holds the housing in a state in which one of the outer surfaces of the housing serving as a housing-side reference surface is in contact with the apparatus-side reference surface; a driving unit that moves the holding unit; an obtaining unit that, in a state in which the housing-side reference surface is in contact with the apparatus-side reference surface, obtains a first output from a held sensor provided in a master module held by the holding unit, and a second output from the at least one held sensor provided in the sensor module held by the holding unit; and a determining unit that determines whether the sensor module passes inspection based on a difference between the first output obtained by the obtaining unit and the second output obtained by the obtaining unit, wherein the driving unit is adapted to move the holding unit in three-dimensional directions.
