Claims

[Claims for Utility Model Registration] 1. A steering wheel provided with an optical communication mechanism for performing optical communication inside the steering wheel or between the steering wheel and a column of a vehicle, wherein the optical communication mechanism includes a common light source. At least two light emitting elements 56, 57 that emit signals and at least one light receiving element 63 that receives the optical signals are provided, and further, at least one of the light emitting elements 56, 57 always emits light. A steering wheel characterized by being provided with switching means 54, 71 that switches each light emitting element 56, 57 to emit light after a certain period of time so that the light emitting elements 56, 57 emit light. 2. The switching means 71 includes a timer 72 that provides the fixed time, and a driving element Q3 connected to the timer 72.
The steering wheel according to claim 1, characterized in that the steering wheel comprises a relay 75 operated by a relay 75. 3. The steering wheel according to claim 1, wherein the switching means 54 is a microcomputer, and the predetermined time is provided by a timer and its counter built into the microcomputer 54. 4. The steering wheel has a non-rotating pad portion, and the light emitting elements 56, 57 and the light receiving element 63 are arranged at positions opposite to each other with respect to the boss plate 6 of the steering wheel. A steering wheel according to claim 1 of the utility model registration claim. 5. The steering wheel according to claim 1, wherein the at least two light emitting elements 56 and 57 are provided close to each other.
