Claims

[Claims for Utility Model Registration] 1. A pair of light emitting elements are arranged at symmetrical positions with respect to a straight line passing through the center of the light receiving element, and the pair of light emitting elements are caused to emit light alternately, so that each light emitting element corresponds to the time when each light emitting element emits light. A tilt sensor that obtains a tilt signal by extracting the difference between the outputs of light receiving elements. 2 Place the light receiving element at the intersection of two orthogonal lines,
disposing one pair of light emitting elements at symmetrical positions with respect to each of the straight lines, and sequentially causing the light emitting elements to emit light;
A tilt sensor characterized in that a tilt signal is obtained by extracting the difference in the output of a light receiving element corresponding to each light emitting element in each pair when each light emitting element emits light. 3. The tilt sensor according to claim 1, wherein three pairs of light emitting elements are connected in antiparallel, and a connection point thereof is connected to a connection terminal.
