PROBLEM TO BE SOLVED: To receive an optical signal always in a stable state with a necessary minimum configuration in optical communication.SOLUTION: A receiver for optical communication 100 is provided, comprising: a light-receiving element 103; a receiving circuit 107a for decoding data superposed as an optical communication signal from light received by the light-receiving element 103; a battery 104 for driving the receiving circuit 107a; a rotating body 102 comprising at least the light-receiving element 103 and the battery 104 arranged at a position of a predetermined angle using a rotational axis as a center; and a housing 101 for holding the rotating body 102. The receiver for optical communication 100 is characterized in that the battery 104 works as a weight and faces toward a gravity direction, and thereby the light-receiving element 103 always faces toward the direction of a predetermined angle. |
