Abstract
PURPOSE:To easily adjust the extent of projection of a head, by constituting so that the video head supported through an electromechanical converting element is made movable in the diameter direction of a rotary body, and a control signal for adjusting the extent of projection of the head is supplied to the converting element. CONSTITUTION:On the space between a rotary drum 1 and a fixed drum 3, round which a video tape 2 has been wound, the tip of a video head 5 is provided so as to project from the outside circumferential surface of the drums 1, 3, and this video head 5 is supported by a bimorph plat 6 functioning as an electromechanical converting element so as to be movable in the diameter direction A of the rotary drum 1. This bimorph plate 6 is installed onto the rotary drum 1. Also, when this bimorph plate 6 is deformed in accordance with an electric signal supplied through a bimorph driving circuit 11 from a contolling circuit 10, the video head 5 moves in the direction as indicated with an arrow A, and the extent of projection of the tip is controlled.
