<P>PROBLEM TO BE SOLVED: To provide an acceleration detecting apparatus capable of improving the detection accuracy. <P>SOLUTION: A weight 3 has a reflecting surface 3a, constituted of a three-dimensional curved surface and is supported at the position of an origin by coil springs 4. A laser device 5 irradiates a light toward the reflecting surface 3a of the weight 3. A two-dimensional optical sensor 6 is arranged at a position, to which light reflected at the reflecting surface 3a of the weight 3 is made incident. The weight 3 is displaced according to the direction and size of acceleration, when acceleration is added. The position of reception of the light irradiated from the laser device 5 by the two-dimensional optical sensor 6 is thereby displaced. A signal processing circuit 9 detects the position of light reception, on the basis of output of the two-dimensional optical sensor 6 and outputs an acceleration detecting signal. A controller 10 computes acceleration from the acceleration detection signal. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
