<p><P>PROBLEM TO BE SOLVED: To provide a drive unit in a novel structure capable of further making a structure simple and compact while restraining noise caused by transmitting a plurality of electric signals. <P>SOLUTION: In a steerable transmitter 10, a pair of first coil members 34a, 34b using inner periphery wall sections 46 as magnetic paths is assembled to a pair of first core members 32, 32, thereby they are coupled in a state of electromagnetic coupling, and thus composing a first transmission path for transmitting at least one of power and a signal between first and second members 12, 14 mutually rotated relatively. Also, in the steerable transmitter 10, a pair of second coil members 36a, 36b using outer peripheral wall sections 48 as magnetic paths is assembled to the pair of first core members 32, 32, thereby they are coupled in a state of electromagnetic coupling, and thus composing a second transmission path for transmitting at least one of power and a signal between the first and second members 12, 14. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
