Abstract

PURPOSE:To limit the deflection of a pre-load spring and the increase in stress by using a moving motor to move a head block fitted with a magnetic head via a belt and arranging a pre-load springback to the deflection side of a pre- load spring fitted to the belt. CONSTITUTION:A cylinder 5 is fitted to a magnetic moving motor 9, a belt 8 is wound around the cylinder 5 and a reinforcement plate 6 fitted to the belt 8 is fitted by a screw 7. One end of the belt 8 is fitted to a belt pin 10 of a head arm 3 rotating around a pivot 11 and the other end is fitted to a pre-load spring 4 fixed to the arm 3. The pre-load springback 12 is fitted to the arm 3 to the deflection side of the spring 4. When the motor 9 is driven, the arm 3 is rotated around the pivot 11 via the belt 8. A magnetic head 2 fitted to the arm 3 is moved while facing the magnetic disc 1 by the rotation of the arm 3. Thus, the deflection of the pre-load spring is limited to prevent jumping of the belt and the increase in stress is limited to prevent break.

[Problems and Objectives to be Solved by the Invention] However, in the above-mentioned prior art, as shown in FIG. 3, the head arm 3 rotates up to 13 degrees per arm degree). When attempting to continue, the force applied to the preload spring 4 includes the torque of the head moving motor, and the maximum stress applied to the preload spring 4 increases. In addition, the side of the hook of the bin 8 on the head arm 3 becomes loose due to the uneasy deflection of the preload spring 4, and the belt hook may come off the bin 10 or the position of the hook on the head arm 3 may be different. There was a problem. The present invention is intended to solve these problems, and its purpose is to prevent unnecessary stress and increase in deflection from being applied to the preload spring.

[Operation] According to the above structure of the present invention, when a force higher than a steady state is applied to the belt and the preload spring is deflected to a value higher than a steady state, the preload spring hits the preload spring degree, and the amount of deflection of the preload spring is limited. . Furthermore, the maximum stress applied to the preload spring is also smaller than when one end is fixed.

As explained above, in the present invention, by arranging the preload spring force on the deflection side of the preload spring, when a force higher than a steady state is applied to the belt, the amount of deflection of the preload spring is limited.
Looseness at the other end of the belt is restricted, preventing the belt from coming off or
Problems such as posture differences are resolved. Furthermore, since the maximum stress of the preload spring is limited, there is no fear of breakage, and a thinner preload spring can be used. If a thin preload spring is used, the amount of deflection due to the preload can be increased, and the preload spring can be easily designed and manufactured.
