The operating handle 104 is an operating handle hole 11 provided in the portable disk module 100.
Passable disk module rotating screw part 11 passing through 3
Inserted in 2. At this time, the operation handle hole 113 is provided with the operation handle projection 10 provided on the operation handle 104.
9 has a shape that allows passage, and a shape that makes it impossible to operate other than the operation handle 104, and prevents the operation handle 104 from being operated by anyone other than the keeper. This plays a role of protecting the data of the magnetic disk device 103. Although the projection 109 is shown in the figure, other shapes, for example, an uneven shape may be used. In addition, in FIG. 4, hole 1
The right-side convex portion formed on 13 is a guide portion when the operation handle 104 is pulled out after the loading of the portable disk module is completed.

FIG. 5 is a diagram for explaining the operation of the rotating screw part of the removable memory when the portable disk module is inserted into the housing 101 of the magnetic disk subsystem. The upper part (a) of FIG. The perspective view of the screw part 112 is shown, the figure of the middle stage (b) shows the figure which looked through the portable disc module 100 from the upper surface, and the figure of the lower stage (c) shows the figure which looked at the portable disc module 100 from the front. .

In FIGS. 4 and 5, 109 is a handle handle projection, 110 is a magnetic disk subsystem substrate, and 1 is a magnetic disk subsystem substrate.
12 is a rotating screw portion on the side of the portable disk module, 113
Is a handlebar hole for operation, 116 is a housing-side receiving portion projection, 11
Reference numeral 7 is a magnetic disk device side connector, 123 is a portable disk module rotary screw operation handle insertion hole, 125
Is the receiving hole for the magnetic disk subsystem chassis side receiving part,

Therefore, the portable disk module 100
When the disk subsystem housing 101 is inserted into the disk subsystem housing 101, there is a clearance in the portable disk module rotation screw portion 112 so as not to project too much from the portable disk module 100 as shown (in the substantially circular rotation screw portion 112, In this state, it is inserted into the housing 101 of the disk subsystem. The portable disk module rotation screw portion 112 abuts on the housing side receiving portion projection 116 provided on the housing 101 of the disk subsystem to prevent the progress in the insertion direction.

Next, the portable disk module 100
In order to drive the insertion, the operation handle 104 is inserted into the operation handle hole 113 and rotated to operate the portable disk module rotation screw portion 112. Since the rotary screw portion 112 is fitted into the housing side receiving portion screw relief hole 125 and the screw portion 112 has a spiral shape, the screw portion 112 is screwed as the screw portion 112 rotates in the direction of the arrow 127. The portable disk module integrated with the unit is driven in the forward direction so that the connector 106 and the connector 107 are electrically connected. Incidentally, in FIG.
Although 2 is illustrated, a known means for converting the rotational movement of the handle into the linear movement of the portable disk module is also a structural example of this embodiment.

The operating handle 104 is moved from the operating handle hole 113 to any position where it can be removed, and is removed. By removing the operation handle 104, it becomes impossible to insert or remove the portable disk module 100.

FIG. 6 is a view showing the positional relationship of the portable disk module 100 inserted in FIG. The upper diagram (a) shows the state of the portable disc module rotation screw portion 112 when the portable disc module 100 is loaded, and the middle diagram (b) shows the portable disc module side connector 106 and the housing side connector 107. Shows the inserted state of. Further, the lower diagram (c) shows the positional relationship of the portable disk module rotation screw portion 112 that gives a driving force to the portable disk module 100.

As described above, the portable disk module attaching / detaching mechanism according to the embodiment of the present invention is arranged in each of the housing and the portable disk module attached to / detached from the housing, and the portable disk module and the housing. A connector part for joining the body to each other, and a positioning means provided in each of the housing and the portable disk module, and aligning the corresponding connector parts with each other when the portable disk module is mounted in the housing. And a rotating screw part that controls the attaching / detaching operation of the portable disk module to / from the housing when the portable disk module is attached / detached to / from the housing, and a rotating screw part when the portable disk module is attached / detached to / from the housing. It is provided with an insertion / extraction force generation unit that is required to be attached to and detached from the housing by being controlled.

Further, in order to prevent an unspecified number of people from easily attaching / detaching the portable disk module, the operating handle is made removable so that the portable disk module cannot be easily attached / detached. Further, the operation handle insertion portion of the portable disk module has a structure that cannot be inserted except the handle. By managing this operating handle, it is possible to provide data protection for the portable disk module.

[0034]
