Patent ID: 7428841

Claim:
An inclination sensor detecting inclined displacement of an electronic apparatus from a standard plane of a basic position, comprising: a sensor chip having a detection plane detecting two-dimensional displacement including an X direction axis and a Y direction axis, wherein a Z axis orthogonal to said detection plane of said sensor chip is disposed in parallel with the standard plane of said electronic apparatus, said sensorchip includes a movable structural portion movable in two-dimensional directions in said detection plane, a substrate accommodating said movable structural portion, and a detecting portion outputting a signal according to displacement of said movable structural portion, the detecting portion of said sensor chip is disposed on the X detection axis extending to be inclined at about 45° from a direction parallel to said standard plane, and on the Y detection axis extending to be inclined at about 45° from a direction vertical to said standard plane, and the inclined displacement of said standard plane with respect to said basic position is determined based on a difference between or a sum of an output signal of said detecting portion on said X detection axis and an output signal of said detecting portion on said Y detection axis.
