  2. Description of the Related Art An information storage device in which a plurality of hard disk drive packs (a hard disk drive with a guide rail or the like attached to the housing) is installed, for example, a hard disk array device is known.

  Since this hard disk array device is equipped with multiple hard disk drive packs, the failure is likely to occur. If a failure occurs, it is necessary to repair or replace the hard disk drive pack. is there.

  In order to replace a failed hard disk drive pack, it is necessary to make the hard disk drive pack easily detachable from the housing of the hard disk array device. For this reason, a certain gap, that is, clearance is required between the hard disk array device and the hard disk drive pack. In order to facilitate replacement of the failed hard disk drive pack, the hard disk drive pack can be inserted and removed from the front side of the housing of the hard disk array device.

  In a recording medium such as a hard disk, performance deterioration due to vibration is likely to occur, for example, a magnetic head damages a rotating disk due to external vibration. In particular, an operating hard disk drive is vulnerable to vibration, and it is important to suppress the vibration. Note that the vibration here refers to self-excited vibration that occurs mainly when the hard disk drive itself operates (the disk rotates or the magnetic head moves), and vibration that is generated from other equipment such as a cooling fan unit. Or, vibration or the like that occurs when a failed hard disk drive pack is inserted and removed from the housing for replacement while the device is in operation.

  The hard disk array device has slots corresponding to the number of hard disk drive packs at the top and bottom or the left and right of the housing of the device. On the other hand, the hard disk drive pack is provided with a guide rail that is inserted into the slot and guides the hard disk drive pack to a predetermined position.

  Further, the hard disk drive pack includes a hard disk drive pack side connector at the distal end side in the insertion / removal direction, and the hard disk array device housing includes a housing side connector at the rear end side. When the hard disk drive pack is inserted into the housing, the connector on the hard disk drive pack side is connected to the connector on the housing side. For this reason, if the hard disk drive pack is inserted into the housing in the wrong direction, for example, upside down, the connector may be damaged. In order to prevent the erroneous insertion, an erroneous insertion prevention structure is required.

  In an electronic apparatus such as a hard disk array device having a disk drive device (corresponding to a hard disk drive pack in the present invention) that is detachably mounted on a housing, two directions (left and right direction and up and down direction) perpendicular to the mounting direction of the disk drive device And a guide rail which is provided on the disk drive device side and is inserted into the slot to guide the disk drive device to a predetermined position. Patent Document 1 is known as a fixing structure of a disk drive device.

  In Patent Document 1, as shown in FIG. 23, a slot 101 provided in a housing (not shown) of an electronic device such as a hard disk array device and a disk drive device (not shown) are provided in the disk drive. A fixing structure for a disk drive device is disclosed, which comprises a guide rail 102 for mounting and fixing the device so as to be insertable / removable with respect to the casing of the electronic device.

  When the guide rail 102 is inserted into the slot 101 and inserted into a predetermined position of the housing of the electronic device, the protrusion 103 provided on one side of the guide rail 102 comes into contact with the fixing plate 104 provided on the slot 101 side. The beam portion 108 (see FIG. 24) is distorted, and the guide rail 102 is pressed against the slot 101 by the stress to fix the disk drive device in the left-right direction, and the raised portion 105 provided on the other side portion of the guide rail 102. Is fitted into a taper groove 106 provided on the slot 101 side, and the guide rail 102 is pressed against the slot 101 to fix the disk drive device in the vertical direction.
