摘要： PURPOSE:To prevent howling and split vibration, by turning a turn table through jetting liquid from a plurality of openings to wings around the turn table floating in a vessel with liquid provided lower than a location of a tank with liquid. CONSTITUTION:A liquid stored in a tank 1 flows to a ring path 3 provided at lower position through a pipe 2. The path 3 is a hollow ring and has a plurality of nozzles 5 located with equal interval on the inside surface and it fitted inside a vessel 6. The liquid is given to the inside the vessel 6, and a turn table 7 is floated inside the path 3 rotatably. The side of external circumference of the turn table 7 is provided with a number of wings 8. The water in the tank 1 is jetted from the nozzles 5 via the pipe 2 and the path 3 and shots the wings 8 of the turn table 7 to turn it. Since the water put in the vessel 6 moves from an overflow outlet 9 to a liquid tank 10, the water level is constant and the location of the turn table 7 is constant up and down direction. Thus, stable rotation is achieved.

摘要： PURPOSE:To eliminate the need for a head base and to decrease the number of parts by attaching directly a head to an attaching surface worked after aseembling of a rotary guide drum. CONSTITUTION:The rotary guide drum 24 is rotatably assembled via a revolving fulcrum shaft 23 and thereafter the surface 28 for attaching the head is worked by using a tool, then the magnetic head 32 is attached thereto. The head 32 is designed to be connected to a coil 27 of a rotor 26 of a rotary transformer 17 via a terminal board 33. The transmission and reception of a signal to and from the stationary side are thus made possible with the head 32 via the rotary transformer 17 and the execution of recording and/or reproducing is made possible by bringing the magnetic tape wound on the outside periphery of a stationary guide drum 16 and a rotary guide drum 24 into contact with the head 32.
