1. An acceleration and angular velocity detector comprising:
- a body mass;
a flexible portion, which is connected to said body mass, that deforms in consonance with displacement of said body mass;
a peripheral support member for supporting said flexible portion;
vibration means for vibrating said body mass circularly;
displacement detection means for independently detecting displacements of said body mass in directions of three axes and for outputting a signal; and
calculation means for detecting accelerations in said three directions and angular velocities around said three axes by employing said signal output by said displacement detection means.

Abstract
An acceleration and angular velocity detector comprises a body mass, a flexible portion, which is connected to the body mass, that deforms in consonance with a displacement of the body mass, and a peripheral support for supporting the flexible portion. A vibration device causes the body mass to vibrate circularly in two dimensions. A displacement detection device independently detects displacements of the body mass in three axes directions and outputs a signal and a signal processor calculates acceleration in the three axes directions and angular velocities around three axes by employing the signal that is output by the displacement detection device.
