DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an apparatus provided with a so-called hard disk as a magnetic storage device,
The present invention relates to a hard disk unit detachable structure to which a hard disk unit can be detachably attached.

[0002]

2. Description of the Related Art In recent years, with the increase in capacity and cost of hard disk units, hard disk units are not limited to computers but may be installed in household appliances such as video recorders and game machines. When a hard disk unit is mounted on a home appliance or the like, an installation structure that allows easy removal of the hard disk for maintenance such as repair or replacement of parts is desired.

Hitherto, various proposals have been made for a mounting structure for facilitating removal of a hard disk. For example, Japanese Patent No. 2560641, Japanese Patent Application Laid-Open No. H8-3107.
0, JP-A-11-149753, JP-A-7-149
No. 50492, JP-A-2000-82884, and the like.

[0004]

In a general hard disk unit, a connector for wiring connection is provided on the rear side of the case according to the standard, and the connector is inserted and removed in the front-rear direction of the case. To remove the hard disk unit, it is necessary to first pull out the connector. Therefore, if no contrivance is made, the workability of attaching and detaching the hard disk will be significantly deteriorated. However, this structure restricts the arrangement of the hard disk and the arrangement of other components in the apparatus, and there is a problem that the degree of freedom in designing the entire apparatus is reduced.

For example, Japanese Patent No. 2560641, Japanese Patent Application Laid-Open No. 8-31070, and Japanese Patent Application Laid-Open No. 11-149
The mounting structure of the hard disk disclosed in Japanese Patent Application Laid-Open No. 753/7550 and Japanese Patent Application Laid-Open No. 7-50492 is designed to be slid forward and backward to be attached and detached, thereby reducing the degree of freedom in designing the entire apparatus.

The mounting structure disclosed in Japanese Patent Application Laid-Open No. 2000-82884 is a structure in which a hard disk unit is attached and detached by moving the hard disk unit not vertically but vertically, but a relay cable for changing the direction of a connector vertically. Since the connector conversion member called assembly is fixed only by connector connection with the hard disk, when the hard disk unit is displaced up and down to attach and detach the connector, the fixing structure of this connector conversion member fluctuates. There was a fear that it would. In addition, since an operation unit called a latch assembly that is moved when the hard disk is removed is provided on the main unit side, if the operation unit is moved while holding the main unit (notebook PC) in a normal direction, the hard disk is moved. There was also a risk of falling off the device by mistake.

An object of the present invention is to improve the workability at the time of maintenance by making the hard disk detachable by sliding the hard disk vertically (in a direction perpendicular to the plane having the largest area). It is an object of the present invention to provide a hard disk unit mounting / removing structure capable of expanding the degree of freedom of design of the entire device, stably connecting a hard disk to a main unit, and safely removing a hard disk.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a first connector for wiring connection, which is housed in a substantially rectangular parallelepiped case and has a rear surface having the smallest area among the surfaces of the case. And a second connector whose insertion / removal direction is oriented in a direction perpendicular to the upper surface having the largest area among the respective surfaces of the case, from the first connector to the second connector. A wiring-connected connector conversion member, a holding bracket to which the hard disk unit and the connector conversion member are fixed together, and a hard disk housing provided on the main device side,
A main body-side connector provided at a position and an orientation corresponding to the second connector of the hard disk housing,
The hard disk unit and the connector conversion member fixed to the holding bracket are inserted into or separated from the hard disk accommodating portion of the main unit in the insertion / removal direction, so that the main unit and the hard disk unit are configured to be detachable. It is a detachable structure.

According to such a means, the hard disk unit can be removed or attached by sliding in the vertical direction (perpendicular to the plane having the largest area). When a hard disk unit is mounted on a device other than a computer, the degree of freedom in design can be increased. Also,
Since the connector conversion member for converting the horizontal first connector to the upward second connector is fixed to the holding bracket together with the hard disk unit, the connection between the hard disk unit and the connector conversion member is firm, and the hard disk unit is connected to the main unit. The connection does not fluctuate when it is attached to or detached from.

Desirably, a lever rotatably attached to the holding metal fitting for releasing the connection between the second connector and the main body side connector, and a lever abutting against the machine frame of the main body device by turning the lever. It is preferable to provide a cam body displaced in the insertion / removal direction.

[0011] By adding such a configuration, even when the connector is firmly connected and a force is required to remove the connector, the connection of the connector can be easily released by levering the lever and the hard disk unit can be removed by rotating the lever. It can be removed from the main unit. Further, since the lever is fixed to the holding bracket together with the hard disk unit, it is possible to prevent a mistake that the hard disk unit is dropped as long as the lever is held. That is, it can be safely removed in a stable state.

[0012] More preferably, the cam body is provided at a position crossing a line extending from the second connector in the insertion / removal direction when the hard disk unit is viewed from the side. Thus, the force applied to the cam body is applied to the second connector without twisting, so that no extra force is applied to the hard disk unit at the time of removal, and the removal can be performed stably.

[0013] More preferably, the hard disk unit is attached to the main unit by screwing the holding bracket and the machine frame of the main unit. As a result, it is possible to avoid inconveniences such as the hard disk unit being accidentally detached other than during maintenance.

[0014]
