INTRODUCTION (I) TECHNICAL FIELD The present invention relates to a disc device that writes and reads data to and from disc-shaped recording media. More particularly, it relates to a disc device used in a laptop's tape type and other small computers. 2. Description of the Related Art In many computer systems, data is recorded on a magnetic film formed on the surface of a disc-shaped recording medium Zhao, such as a hard disk or a floppy disk. The data is written or read by magnetic heads in concentric circles of magnetic film. When data is written and read, the magnetic head is a thin laminar flow boundary layer of air formed on a high-speed rotating disc, and is configured so that the magnetic head does not directly contact the magnetic surface. A magnetic head is generally mounted near the front end of the actuator on the drive mechanism of the disc device. Rotary actuators revolve around a rotating shaft arranged near the periphery of the disc. The magnetic head at the front end of the actuator revolves by drawing a certain arc on the surface of the disc. In the case of a rotary actuator, the mass of the rotating shaft cylinder of the rod-shaped element is substantially formed into a balanced shape. Therefore, when an impact in a completely straight direction is applied to the disc device, the impact force will equally act on both sides of the rotary shaft of the actuator, and it will not act on the actuator at all. In addition, in the manufacturing process, due to the general difference in dimensions and other differences in the quality of the small uneven situation 'when receiving an impact in a completely straight direction, there will be no comparison that will cause the non-powered locking mechanism to disengage. Large inertial force. The conventional rotary actuator is configured to revolve slightly with the axis of rotation as the center of rotation, so it is susceptible to the impact and acceleration of the force applied in the direction of rotation. This paper applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 4 '------------------ ^ (Please read the note on the back and fill in this page first) Λ, Β7 V. Description of the invention (Impact It is easy to move: Therefore, it must be provided with a protective structure that does not move under the influence of the inertial force when the actuator is impacted in the direction of rotation. The reason is that the rotary actuator has a rotating wheel as the center ^ and 2The structure of the disk that is easy to shake is drawn on the surface of the disc, so it is necessary to prevent the magnetic head arranged near the front end of the actuator from making unnecessary contact with the disc. The necessity of such a protection mechanism is accompanied by the laptop and the The development of smaller computers is important. Especially those who use the above-mentioned computer devices use it under bad conditions or carry towels or do not shake the tadpoles or bump them into other objects. Sometimes they will fall. When a strong impact is applied in the direction of rotation. For the above-mentioned impact, it is proposed to have a protection mechanism that will surely maintain a specific position when the drive mechanism of the disc is inactive. For example, the figure disclosed in the invention of Japanese invention 27 i 8573 (No. 1)圊) A conventional protective mechanism is shown in the middle. This protective mechanism is provided with an inertial card that can temporarily engage with the protrusion on one end of the actuator when the disc device is applied with a strong angular acceleration force in a clockwise direction. Lock structure. This inertial latching mechanism w is used to spring the inertial body {the term of the patent publication) to the non-latching position: when the angular force is generated by the impact force applied to the disc device, the inertial moment generated by the inertial body will exceed The spring pressure of the spring causes the inertial body to revolve to form a latching actuator. Therefore, the inertial latching mechanism known for low-level external impact forces that the inertia moment does not exceed the rated pressure of the spring will not be able to send ± n S The problem t η η K i is constructed in accordance with the requirements of the times, and the type is '~ II': 5i 丄 .Λ ·.

Zt6086 A A. Description of the invention (3) The size is getting smaller and smaller. Therefore, it is difficult to construct a conventional disc device that makes the inertia moment generated more than the elastic pressure. It is difficult to shape β on the one hand. On the one hand, it is also envisaged that a structure with a large inertia moment is not formed, and the spring is reduced by miniaturizing the spring. The method of pressure, but because of the shortcomings of the spring's workability, assembly, and erroneous action caused by friction, the miniaturization of the spring is very problematic. Therefore, the problem that the conventional inertia latch mechanism cannot function when subjected to a low-level external impact force is even more serious on an ultra-small drive mechanism such as a one-inch β inch. The problem of ineffectiveness caused by the above-mentioned low-level external impact force is disclosed in Japanese Patent Application Laid-Open No. 8-339645. These protection mechanisms are articles with magnetic lock structure that use magnetic force together with the inertia lock structure, and are double lock mechanisms that can respond to low, medium and high-level impact forces of various degrees. However, the protective mechanism of this structure has a high manufacturing cost and has problems in that it is not easy to assemble the inertia latch structure and the two latch structures of the magnetic latch mechanism on the ultra-small disc device. DISCLOSURE OF THE INVENTION An object of the present invention is to provide a structure that is simpler than a conventional disc device in order to solve the foregoing problems, and is free from the impact force of an actuator when an impact force is applied to the disc device when the disc is inactive.

When the inertial latching mechanism 3 1 丨 of the fourth embodiment is located at the position shown in FIG. 29, the inertial latching mechanism 311 is a latching actuator 3. Therefore, in this case, the magnetic head will not move on the surface of the disc 2 even if a rotary impact force is applied from the outside of the disc device. On the one hand, when the inertial latch mechanism 311 of the fourth embodiment is located in FIG. When the position is at the middle position between the 27th circle and the 29th circle, when the disc device receives a clockwise turning impact force, the inertial latching mechanism 311 instantly moves in the counterclockwise direction. As a result, the inner side portion of the hook portion 343 is in contact with the finger portion 45 of the actuator 3, and is in a state not like that of Naomi. In this state, the 'hook portion 343 is located at the position where the finger-shaped bucket 5 can be engaged, and the counterclockwise rotation of the actuator 3 can be prevented. When the disc device is non-actuated, the cam follower 6 of the actuator 3 contacts the block 7, so frictional force will be generated in the meantime. Thereby, even if a slightly smaller turning impact force is applied to the disc device, the return of the actuator 3 will be suppressed by the impact. On the one hand, the inertial latching mechanism 3 丨 丨 is not provided with spring gear and the like to suppress its movement. Therefore, even if a clockwise turning impact force is applied to the disc device, the inertial latch mechanism 3 11 will rotate relatively counterclockwise instantaneously. Since the disc device of Embodiment 4 has the structure as described above, the inertial latching mechanism 3 丨 is rotated counterclockwise than the actuator 3. Therefore, the finger portion 45 does not erroneously engage with the hook portion. Next, a description will be given of a case where a counterclockwise turning impact force is applied to the disc device of the fourth embodiment.
