Abstract

PURPOSE:To eliminate readjustment of bias errors and to reduce the cost by forming the 1st frame in a piece of block. CONSTITUTION:The 1st frame 4 is made in a piece of a block and when an acceleration acts in the direction of X-X axis of the central axis of the frame 4, a pendulum 1 is minutely displaced with a thinner part 2 of a hinge 3 as a fulcrum, and with shading or division by the pendulum 1 from a luminous element 11, incident light to light emitting elements 10, 10' of a displacement detector varies and from these an electric signal corresponding to the displacement is obtd. The electric current proportional to this electric signal is fed back to torque coils 7, 7'. The pendulum 1 is restrained thereby so as to make the electric signal of the elements 10, 10' to zero. This restrained current is proportional to the acceleration and by measuring the electric current, the input acceleration can be known. The readjustment of bias errors can be thus eliminated and the cost is reduced.
