PURPOSE:To store receiving coils in an extremely small space by supporting a 2nd shaft rotatably at right angles on the intermediate part of a 1st shaft supported rotatably on a bracket and supporting and fixing receiving coils at both side part of the 2nd shaft. CONSTITUTION:Both end parts of the 1st shaft 1 are supported rotatably on right and left brackets 2 rotatably and the intermediate part of the 2nd shaft 3 is supported at the intermediate part of the 1st shaft 1 at right angles to the 1st shaft. Then, the upper parts of the receiving coils 4a and 4b are fixed at both end parts of the 2nd shaft 3 at positions of the same size from the support parts for the 1st shaft 1. Thus, the receiving coils 4a and 4b are fixed and then stored in the extremely small space. Further, both receiving coils 4a and 4b shift in phase by 90 deg. to right and left when viewed from the front and are equal in weight, and they can be held at invariably constant attitudes to gravitation by their own weights. |
