Description

Description: TECHNICAL FIELD The present invention relates to a storage device mounting structure in which a plurality of mechanism decks are housed in a housing.

[Prior Art] FIGS. 10 to 12 show a conventional storage device mounting structure.

In each drawing, 1 is a housing, 2 is an opening / closing door, 3 is a mechanism section deck which is vertically stacked in a plurality of layers in the housing 1 through slide rails 4, and the mechanism section deck 3 is a storage medium. The main body mechanism section 5 is provided with a magnetic disk, a magnetic head (not shown) and a motor for driving them, a power source 6 for driving the main body mechanism section 5, a substrate 7, etc. The inside of 1 is partitioned into a portion for housing the mechanism portion deck 3 and a device controller portion 8. Casters 9, 9, ... Are provided on the bottom surface 1a (4 places) of the housing 1,
Further, a total of six adjusting legs 10, 10 ... are provided at the corners (4 places) of the bottom surface 1a and one at the front and rear edges in the center, and an adjuster 11 that moves in the vertical direction is provided at the tip end side thereof. ing. The adjusting legs provided at the four corners of the bottom surface 1a of the housing 1
The supporting legs 13 fixed to the slab floor 12 with bolts 12s facing the 10, 10 ... Face the opening 14a of the free access floor 14,
The adjuster 11 is placed on the support leg 13, and the coupler 15 as a fixture connects and fixes the both.
That is, the housing 1 is fixed to the slab floor 12 via the leg portion 16 including the adjusting leg 10, the adjuster 11, the coupler 15, the supporting leg 13 and the like. When it is desired to move the housing 1, the coupler 15 is removed, the adjuster 11 is raised, the length of the adjusting leg 10 is made shorter than the length of the caster 9, and the caster 9 is grounded to the free access floor 14. When fixing to the slab floor 12, after moving the adjusting leg 10 to the position of the supporting leg 13, the adjuster 11 is moved until the caster 9 is separated from the free access floor 14.
In this state, the adjusting leg 10 and the support leg 13 are fixed by the coupler 15 to prevent the housing 1 from moving and falling down in the event of an earthquake.

[Problems to be Solved by the Invention] According to the conventional storage device mounting structure, in the event of an earthquake or the like, the housing 1 is fixed to the slab floor 12 via the leg portions 16, and therefore, the fall is prevented. However, since the vibration of the slab floor 12 is directly transmitted to the housing 1 via the legs 16, the housing 1 is greatly shaken. For this reason, there has been a problem that the mechanism section deck 3 housed in the housing 1 and susceptible to vibration is easily damaged.

The present invention has been made in order to solve the above problems, and is a structure for mounting a recording device, which can prevent the storage device housing from vibrating and falling down in the event of an earthquake or the like and does not damage the mechanism deck in the housing. Is to get.

[Means for Solving the Problem] A substrate facing the bottom surface side of a storage device housing is provided, legs are provided on this substrate, and a vibration absorbing portion made of an elastic member is provided between the bottom surface of the housing and the substrate. Intervened.

[Operation] In the event of an earthquake or the like, the storage device housing is fixed to the floor via the legs so that it does not tip over, and the vibration absorber absorbs vibrations and shakes from the floor, causing vibrations and shakes of the housing. Suppress.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 1 to 9. It should be noted that the same or corresponding parts as those of the conventional example shown in FIGS.

In each drawing, reference numeral 20 denotes a substrate arranged so as to face the bottom surface 1a side of the housing 1, and a vibration absorbing portion 21 is interposed between the substrate 20 and the bottom surface 1a of the housing 1 to make The bottom portion 20a is provided with the leg portion 16 and the casters 9, 9, ... As in the conventional case. As shown in FIG.
It is composed of a two-stage structure in which a ring-shaped elastic member 23 is interposed between a plurality of disc metal fittings 22, and is connected to upper and lower disc metal fittings 22, 22 ... Through rivets 24. A hole 22a formed in the diameter of the head 24a of the rivet 24 is formed in the peripheral edge of the disc fitting 22.
And six 22b formed every other bolt at the bolt diameter of the rivet 24 at predetermined intervals. Correspondingly, six circumferentially upper and lower surfaces of the elastic member 23 also penetrate vertically. Holes, that is, 23a facing the upper and lower holes 22a, 23 facing the holes 22b
b is formed. The elastic member 23 is sandwiched between two upper and lower disc fittings 22, 22, and a rivet is provided through the hole 22a of the upper disc fitting 22.
24 is inserted and the tip is fixed in the hole 22b of the lower disc metal fitting 22, and the rivet 14 is also inserted from the empty hole 22a of the lower disc metal fitting 22 to insert the disc metal fitting 22 on the tip. It is fixed in the hole 22b. The vibration absorbing portion 21 is formed by stacking the two layers. The through holes 23a and 23b have stepped portions 23s as shown in FIG.
Is formed, and the rivet head 14a is locked to this step portion 23s,
The elastic member 23 and the disk-shaped metal fitting 22 are prevented from coming off.
Mounting bolts 25, 25 are provided in the bolt holes 22p, 22p at the center of the upper and lower disc fittings 22, 22 of the vibration absorbing portion 21, whereby the upper disc fitting 22 is placed on the bottom surface of the housing 1. In FIG. 1a, the lower disc fitting 22 is attached to the upper surface 20a of the substrate 20.

 Next, the operation will be described with reference to FIGS.

For example, when a rolling earthquake occurs, the substrate 20 fixed to the slab floor 12 side as shown in FIGS.
However, since the vibration absorber 21 absorbs this rolling vibration, the rolling vibration of the housing 1 is attenuated. Further, even in the case of a direct type (longitudinal) earthquake, the vibration absorbing portion 21 expands and contracts in the vertical direction as shown in FIGS. 7 and 8 to suppress the vertical vibration of the housing 1. Further, as shown in FIG. 9, for example, when the vibration absorbing portion 21 on one side is expanded by the maximum extension dimension h1 and the other vibration absorbing portion 21 is contracted by the minimum contraction dimension h2, the housing is tilted 0 °. However, since the center of gravity G1 of the casing and the perpendicular G1-G2 of the center of gravity G1 do not fall over unless the casing 1 is moved outside the center position J of the vibration absorbing portion 21 at the center of rotation, the casing 1 is practically the casing. 1 does not fall. Therefore, it is possible to protect the mechanism section deck 3 in which the housing 1 is housed from vibration and fall due to an earthquake or the like.

Although the vibration absorbing portion has a two-stage structure, it may have a one-stage structure or two-stage or more structures, and may have another shape instead of a ring shape.

[Effects of the Invention] As described above, according to the present invention, a substrate facing the bottom surface side of a storage device housing is provided, and the legs are provided on this substrate, and the bottom surface of the housing and the board are provided. Since a vibration absorbing part made of an elastic material is interposed between them, it is possible to prevent vibration and overturning of the storage device housing during an earthquake, etc., and to provide a storage device mounting structure that does not damage the mechanism deck inside the housing. To be
