Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a magnetic storage device installed in a magnetic disk device.

Conventionally, a magnetic storage device of a magnetic disk device has a storage medium 2 on the bottom surface of a lid 1, as shown in FIG.
The fixing mechanism 3 is provided with a rotating body 4 that rotates the storage medium 2 when the lid 1 is closed, and the fixing mechanism 3 separates from the medium 2 when the lid 1 is opened. It is configured to be pushed out to the outside (to the left in FIG. 1) by being biased by a medium delivery mechanism (not shown). To explain this in detail, the lid 1 consists of a lid 5 and a lid support 6 connected thereto, and rotates around a fulcrum 7 of the support 6 to the position shown by the broken line in FIG. 1 when opened. It is configured. When the lid 1 is closed, it is kept closed by a latch 8 that locks the lid 5, but when this lock is released, an elastic member such as a spring attached to the end of the support 6 9, the lid body 1 rotates and opens about the fulcrum 7 as described above.

As shown in FIGS. 1 and 2, the fixing mechanism 3 has an elastic body 1 made of a spring or the like attached to the bottom surface of the lid support 6.
A push-down body 11 is vertically disposed through a
When the lid 1 is closed, as shown in FIG. 1, the medium 2 on the rotating body 4 is pressed so that the medium 2 can rotate with the rotating body 4, and when the lid 1 is opened, as shown in FIG. As shown, as the lid 1 rotates, it is separated from the medium 2. Note that 12 is a stopper for stopping the rotation of the lid body 1.

When the lid is opened, the storage medium is sent out to the outside. However, in the conventional device described above, the opening operation of the lid is insufficient and the storage medium fixing mechanism is separated from the medium and the rotating body. If the fixing mechanism or the lid comes into contact with the storage medium due to imperfections or a rebound phenomenon caused by the lid coming into contact with the stopper, the delivery of the medium may be hindered, and the performance, function, or performance of the medium may be impaired. This had the disadvantage that even the medium itself was damaged.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and is a magnetic storage device that allows the storage medium fixing mechanism as well as the lid to be completely separated from the rotating body and the storage medium when the lid is opened. It is an object of the present invention to provide a magnetic disk device having a magnetic disk device.

Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

The magnetic disk device of the present invention is a conventional magnetic storage device shown in FIG. 1 with a cover separation mechanism A shown in FIG.
This mechanism A is shown in FIG.
A wedge contact portion 14 is provided protrudingly at an appropriate position on the lower surface portion 13 of the support body 6 constituting the lid body 1, and a wedge contact portion 14 is provided in one direction on a guide surface 15 corresponding to the contact portion 14 by an elastic body 16 made of a spring or the like. It is constructed by slidably providing a wedge 17 that can be biased.

The wedge contact portion 14 has a chevron-shaped side surface as shown in FIG. 3, and is protruded between the vertical fixing mechanism 3 and the pivot point 7 of the lower surface portion 13 of the support body.

The wedge 17 has an inclined surface 18 connected to the contact portion 1.
4 and is slidably provided on a guide surface 15, and when this wedge 17 is biased by an elastic body 16 and moves to the left from the contact position with the contact portion 14 shown in FIG. The contact portion 14 relatively slides on the inclined surface 18, and as a result, the support 6
rotates clockwise in FIG. 3 about the fulcrum 7. That is, the contact portion 14 is regulated by the inclined surface 18 to urge the lid 1 to open, and thereby the lid 1 as well as the fixing mechanism 3 are separated from the rotating body 4 and the storage medium 2. It is something that can be completely divorced. Further, even if the lid body 1 rotates open and comes into contact with the stopper 12, and a rebound phenomenon occurs due to the reaction force, the contact portion 14 will come into contact with the upper part of the inclined surface 18 of the wedge 17. , the pressing body 11 of the fixing mechanism 3 never comes into contact with the storage medium 2 or the rotating body 4.

When closing the lid 1, the contact portion 14
comes into contact with the wedge inclined surface 18, and when the lid body 1 is further pressed by hand, relative sliding occurs between the contact portion 14 and the inclined surface 18, and the wedge 17 moves to the right in FIG. The energy for the next opening of the lid 1 is stored in the elastic body 16 connected to the wedge 17.

Note that the wedge contact portion 14 that contacts the wedge inclined surface 18 and slides relative to it is not limited to the above example; for example, a rotor or the like may be provided, and the mounting position of the elastic body 16 that biases the wedge 17 may also be changed. Of course, the present invention is not limited to the above embodiments.

As explained above, the present invention includes a wedge contact portion protruding from the lower surface of the lid support at a proper location, and a wedge that is biased in one direction by an elastic body and slides on a guide surface corresponding to the contact portion. Since the structure is arranged freely, the lid and the medium fixing mechanism can be completely separated from the storage medium and the rotating body when the lid is opened, and furthermore, the rebound of the opening rotation of the lid can prevent the storage medium, etc. This has the effect that it is possible to avoid situations in which people come into contact with each other.
