特徴とする相対角度センサー。[Claims for Utility Model Registration] 1. A plate-shaped pendulum 3 in which a plurality of slits 1 are arranged in an arc shape is sandwiched between the pendulums 3 and 1 on one side of the pendulum, on the vertical center line of the pendulum, and on one side of the slits located on this center line. Light emitting elements 4 and 5 are arranged on the line, and light receiving elements 6 and 7 are arranged on the other side at positions corresponding to the light emitting elements, and output is generated when there is a state change in both of the above two light receiving elements. A relative angle sensor configured to emit a signal. 2 A plurality of slits 1 are provided in a circular arc shape on a plate-shaped pendulum 3, with one pitch being twice the slit width, and the arc positions are shifted with respect to the slits, and the pitch is shifted by 1/4 to form the slits 1. A plurality of slits 2 having the same angular width are provided, and two light emitting elements 4 and 5 are placed on one side of the pendulum 3 at positions corresponding to both slits 1 and 2 on the vertical center line of the pendulum. In addition, on the other side, light receiving elements 6 and 7 are arranged at positions corresponding to the light emitting element, and an output signal is emitted when there is a change in the state of both of the two light receiving elements. Features a relative angle sensor.
