PURPOSE:To improve signal transmission between a rotary part and a fixed part to large capacity by a simple constitution by providing this non-contact signal transmitting equipment with plural light emitting means and light receiv ing means for independently transmitting/receiving signals to/from a transmitting system structure and a receiving system structure. CONSTITUTION:A rotor part on the rotary part side is constituted of a radiant- ray source 11, a detector 13, a data collecting part 15, a data distributing unit 17, a rotational angle sensor 19, a controller 21, a laser driver 23, and a laser emitting part 1. A stator part on the supporting part side for supporting the rotor part is constituted of a reflector 3, a light receiving part 5 and a synthetic unit part 25. Thus, plural light emitting means are arranged on the signal send ing side and independently emit light correspondingly to plural supplied signals. Plural light receiving means respectively independently receive signals indepen dently sent from the light emitting means. Consequently the transmission volume of data can be improved. |
