No inconvenience such as destruction or deformation of parts such as the SCA 19 and 50 due to the drop impact of the DD unit 15 occurs.

When the inserting direction of the HDD unit 15 into the slot 28 is different between the front and the rear, the stopper projection 18 of the frame 12 abuts against the stopper 33a of the guide member 31, and further insertion or intrusion occurs. I cannot do it. Therefore, an unreasonable connection operation due to erroneous insertion is eliminated, and not only can damage to the SCA 19 and 50 be prevented, but also erroneous connection can be prevented.

As can be understood from the above description, in the operation of inserting the HDD unit 15 into the support means 20, the initial insertion is relatively smooth, and the lower end of the frame 12 and the guide member 31 are inserted during the insertion. Buffer 37
When the upper end of the guide member 31 and the buffer portion 17 of the frame 12 come into contact with each other, a predetermined insertion resistance is generated. , That is, accurate position regulation is performed. Therefore, the frame 12 of the HDD unit 15 and the guide member 31 attached to the slot 28 are configured to reliably perform accurate position regulation and accidental drop prevention.

In any case, the HDD unit can be inserted into and removed from the support means 20 attached to the apparatus main body of the AV server in the vertical direction, that is, in the vertical direction. By simply inserting into the slot 28 without considering the alignment, accurate and smooth insertion is achieved, and the HDD units are vertically aligned, and ventilation holes are provided between the slots 28. Therefore, most of the HDD units are exposed to the ventilation holes in a state of being exposed, and are efficiently contacted with the cooling air to be cooled. In the present invention, the AV server has been described as an example. However, the present invention is not limited to this, and can be applied to other servers.
