Abstract

PURPOSE:To prevent the torsional breaking of an antenna cable by setting the rotation angle of a stabilizing table for antenna control within prescribed range. CONSTITUTION:A rotation-angle setting device 30 consists of projection pine 311 and 312 fitted at the side of a turntable 12, and an angle setter body 32 driven by those projection pins. The main body 32 is provided with a polyhedral turning body 33 having projections 35a-35c and a cam plate 36 fixed on the upper end surface of the polyhedral turning body 33, and when the projection pins 311 and 312 contact with the projections 35a-35c, engagement positions between a detent roller 40 provided to a lever 37 and notch parts 36a-36c provided to the cam plate 36 shift by one. In the figure, since there are three projections 35a-35c, the projection 35a or 35c at the end contacts with a stopper 411 or 412 when the projections contact with the projection pin 311 or 312 three times in one direction at a maximum, thereby stopping further rotation. Increasing the number of the projections 35a-35c increases the rotation angle.
