Abstract

PURPOSE:To simplify a driving mechanism to make it small-sized and light- weight, by attaching a step motor and a microphone holder as one body to a mobile table and running freely them on a rail. CONSTITUTION:A rail 26 is a long-sized material having a channel-shaped section, and a chain 27 is stretched and fixed on the inside face in the longitudinal direction. In a mobile table 28, side plates 29 and 30 are connected and fixed by a connection rod 31, and a roller 33 is supported freely rotatably on a shaft 32. A holder 35 supporting a mobile microphone 34 is fixed to the side plate 30 of the mobile table 28, and a step motor 37 is fixed to the side plate 29. In a mobile wave detector, when the step motor 37 is rotated, this rotation is transmitted to a sprocket gear 39 through a reduction gear mechanism 38 to rotate the sprocket gear 39. Since this sprocket gear 39 bites the chain 27, the mobile table 28 and the microphone holder 35 and the step motor 37 fixed to the left and the right of the mobile table 28 are guided and run by the roller 33, which rolls on the rail 26, when the step motor 37 is rotated.
