Abstract

PURPOSE:To secure the simple and assured exchange of the electromagnet coil frame as well as enhance the assembling and maintenance properties by forming the position regulating groove part of the center magnet to the inside surface in the width direction of the slender yoke frame. CONSTITUTION:For electromagnetic driving device 8 which shifts the magnetic head forth and back via the truck driving, magnetic substance 10 is attached to the surfaces of upper plate 9a and substrate 9b of frame-type yoke 9 as well as to yoke 9 itself each. And center magnet 12 is positioned at the middle of these substances 10 along with electromagnetic coil frame 11 inserted to the circumference side. Furthermore, groove part 13 is formed on the inside surface of the pair of end plates 9b at the both sides of yoke 9 to be engaged with the end part of magnet 12. At the same time, the support arm is attached to attachment part 14 formed into a body with coil frame 11, and also the roller which moves in response to the rotation of the rotary main axle is provided to the tip of the support arm. In such constitution, the exchange can be performed in a simple and assured way for the coil frame, thus enhancing the assembling and maintenance properties.
