Japanese Patent JP3359684
Kind Code:
B2
Abstract:
PURPOSE:To provide a signal transmitter in which simple and high precision signal transmission can be attained according to a transmitted signal, in the non-contact signal transmission when a transmitting part and a receiving part are relatively rotated. CONSTITUTION:A transmitting part 100 and a receiving part 150 are connected with the same axis and integrated so as to be rotatable in each circumferential direction. When the faced faces are enclosed, electromagnetic shield is attained. When the transmitting part 100 is connected with the receiving part 150, a picture transmitting element board 102 and a picture receiving element board 152 are opposed to each other in a non-contact state with a prescribed spacing inside a groove. Also, a synchronizing signal transmitting element board 154 and a synchronizing signal receiving element board 105 are opposed to each other in a non-contact state inside the groove. The transmitting part 100 and the receiving part 150 are always opposed to each other even when the transmitting part 100 is rotated, and the transmitting part 100 transmits a signal. The transmitting part 100 and the receiving part 150 are formed of, for example, Al(aluminuium) or the like.
