Description

The present invention for vibration isolation support device, a storage apparatus having an image forming apparatus and a support device having a support device.

  2. Description of the Related Art A hard disk drive (HDD: Hard Disk Drive) is widely used as a storage device in various devices.

  Here, consider a case where a hard disk drive is mounted on, for example, an image forming apparatus. During operation, the image forming apparatus vibrates due to conveyance of recording paper in the apparatus. Such vibrations also affect the hard disk drive, leading to read and write errors in the hard disk drive or damage to the hard disk drive.

  Therefore, an anti-vibration damper (hereinafter, appropriately referred to as a "damper") is attached to a hard disk drive against shaking of the hard disk.

  An example of such a technique of attaching a damper to a hard disk drive is described in Patent Document 1. In the technique described in Patent Document 1, a screw for attaching a damper and a grounding piece are electrically connected. As a result, in Patent Document 1, it is possible to connect the hard disk drive to the ground via the bracket without impairing the vibration damping action and without adding extra parts.

JP 2012-14749 A

  By utilizing the technology described in Patent Document 1 described above, vibration of the hard disk drive can be suppressed. However, such a technique has the following problems. This problem will be described with reference to FIG.

  First, a general configuration using a damper is shown on the left side of FIG. In such a configuration, the mounting plate 110 and the hard disk drive 100 are connected via four dampers 120. Here, the four dampers 120 are installed in a direction parallel to the rotation surface of the disk that rotates inside the housing of the hard disk drive 100. With such a configuration, it is possible to suppress vibration in a direction parallel to the rotation surface of the disk.

  However, instead of installing the hard disk drive in the parallel direction as shown on the left side of FIG. 1, the hard disk drive is set up vertically as shown on the right side of FIG. 1 due to the space inside the image forming apparatus. It is also conceivable to install it.

  Here, when the hard disk drive is installed upright in the vertical direction as shown on the right side of FIG. 1, a load is applied in the direction of gravity. The weight limit of the damper varies depending on the mounting direction. For this reason, there is a problem that it is difficult to maintain the damper performance when the device is set upright in the vertical direction as shown on the right side of FIG.

  For example, the configuration described in Patent Document 1 also has a configuration in which four dampers are installed in a direction parallel to the rotation surface of a disk that rotates inside the housing of a hard disk drive, as shown on the left side of FIG. It cannot be solved.

Accordingly, an object of the present invention is to provide a support device, an image forming apparatus including the support device, and a storage device including the support device, which are capable of preventing vibrations in a plurality of directions.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

<First embodiment>
First, the configuration of the present embodiment will be described with reference to FIGS. Here, FIGS. 2 to 5 are all diagrams illustrating the configuration of the present embodiment. More specifically, FIG. 2 illustrates this embodiment on the rotating surface of a disk in a hard disk drive as shown on the left side of FIG. It is a perspective view of the state installed in the parallel direction with respect to it. FIG. 3 is a perspective view showing a state in which the present embodiment is installed in a direction perpendicular to the rotation surface of the disk in the hard disk drive as shown on the right side of FIG. Further, FIG. 4 is a view when the present embodiment is installed in the vertical direction, as in FIG. 3, when facing directly from the hard disk drive side, not from the base mounting plate side. Further, FIG. 5 is a left side view when the present embodiment is installed in the vertical direction similarly to FIG.

  First, referring to FIGS. 2 and 3, as a configuration of the present embodiment, a hard disk drive 10, a base mounting plate 20, an auxiliary mounting plate 30, a first damper 41, a plurality of second dampers 42, a plurality of auxiliary plates A mounting screw 50 is shown.

  Here, the present embodiment is for connecting the hard disk drive 10 to the base mounting plate 20. The hard disk drive 10 does not necessarily need to be a hard disk drive unique to the present embodiment, and may be a general-purpose hard disk drive. The base mounting plate 20 may be an arbitrary plate, and is realized by, for example, a sheet metal forming a housing inside the image forming apparatus.

  The base mounting plate 20 has an L-shape, and a surface forming the short side of the L-shape of the base mounting plate 20 and a housing portion perpendicular to the disk rotation surface of the hard disk drive 10 are attached to the base mounting plate 20. Are connected via two second dampers 42 arranged on the surface constituting the short side of the L-shape. That is, the surface of the hard disk drive 10 in the direction perpendicular to the disk rotation surface is supported by the two second dampers 42.

  On the other hand, the auxiliary mounting plate 30 also has an L shape, and the surface forming one side of the L shape of the auxiliary mounting plate 30 and the surface forming the long side of the L shape of the base mounting plate 20 are as follows. Are connected via two first dampers 41 (one first damper 41 is not shown) arranged on the surface forming the long side of the L-shape of the base mounting plate 20. Further, a surface constituting the other side which is not connected to the L-shaped base mounting plate 20 and a housing portion in a direction parallel to the disk rotation surface of the hard disk drive 10 are connected by auxiliary plate mounting screws 50. Specifically, an auxiliary plate mounting screw 50 is inserted into a hole provided in the auxiliary mounting plate 30, and a shaft portion of the auxiliary plate mounting screw 50 is screwed into a screw hole provided in a housing of the hard disk drive 10. The hard disk drive 10 is fixed to the auxiliary mounting plate 30 by the joint fastening. Thereby, the surface of the hard disk drive 10 in the direction parallel to the disk rotation surface is supported by the two first dampers 41 via the auxiliary mounting plate 30.

  In addition, the structure of the 1st damper 41 and the 2nd damper 42 and the detail of the attachment method are mentioned later.

  Next, referring to FIG. 4, a damper mounting screw 60 for connecting the second damper 42 is shown in addition to the above-described parts. As described above, the housing portion in the direction perpendicular to the disk rotation surface of the hard disk drive 10 is connected via the two second dampers 42 arranged on the surface constituting the short side of the L-shape of the base mounting plate 20. Is done. Here, a through hole is provided in the second damper 42 in the axial direction. A cylindrical spacer is inserted into the through hole. Then, the damper mounting screw 60 is inserted into the spacer, and the shaft portion of the damper mounting screw 60 is screwed and fastened to a screw hole provided in the housing of the hard disk drive 10, thereby forming the second damper 42. The base mounting plate 20 is fixed to the hard disk drive 10 via.

  Note that a portion described as “connector” in the central portion on the left side in the figure is a connection portion for connecting a cable conforming to the standard of the hard disk drive 10 when the hard disk drive 10 is used.

  Next, referring to FIG. 5, in addition to the components described above, a damper mounting screw 60 for further connecting the first damper 41 is shown. As described above, the surface forming one side of the L-shape of the auxiliary mounting plate 30 and the surface forming the long side of the L-shape of the base mounting plate 20 are defined by the long side of the L-shape of the base mounting plate 20. The connection is made via two first dampers 41 arranged on the surface to be configured. Here, similarly to the second damper 42, the first damper 41 has a through hole formed in the inside thereof in the axial direction. And, similarly to the second damper 42, a cylindrical spacer is inserted into the through hole of the first damper 41. Then, the damper mounting screw 60 is inserted into the inside of the spacer. Further, the screw 60 for mounting the damper is inserted into a hole provided on the surface of the base mounting plate 20 which forms the long side of the L-shape. Then, the shaft portion of the damper mounting screw 60 that penetrates the hole provided on the surface forming the long side of the L-shape of the base mounting plate 20 is screwed and fastened to the nut via the first damper 41. The base mounting plate 20 is fixed to the auxiliary mounting plate 30.

  Note that FIG. 4 is a diagram when facing from the left side of the hard disk drive, but a diagram showing a configuration when facing from the left side of the hard disk drive is a reverse of FIG.

  In this embodiment, as described above, the first damper 41 is arranged in a direction parallel to the disk rotation surface of the hard disk drive 10 to support the hard disk drive 10 and furthermore, to the disk rotation surface of the hard disk drive 10. A second damper 42 is arranged in a direction perpendicular to the direction, and supports the hard disk drive 10.

  For this reason, in the present embodiment, vibrations not only in the direction parallel to the disk rotation surface of the hard disk drive 10 but also in the direction perpendicular to the disk rotation surface can be reduced, and the life of the hard disk drive 10 can be greatly extended. It has the effect of being able to. In particular, since the second damper 42 located below in the vertical direction is considered to have a greater load due to gravity than the first damper 41, the second damper 42 is disposed and the hard disk drive 10 is disposed. Support is beneficial. Further, in the present embodiment, four dampers are used as in the general configuration described with reference to FIG. 1, and the number of dampers to be used does not have to be increased.

  Next, the structure and mounting method of the first damper 41 and the second damper 42 will be described with reference to FIGS. The third damper 43 described later has the same structure as the first damper 41 and the second damper 42, and has the same mounting method. In the following description with reference to FIGS. 6 and 6, the first damper 41, the second damper 42, and the third damper 43 are collectively described as a damper 70.

  First, referring to the upper left of FIG. 6, the appearance of the damper 70 is illustrated. The damper 70 has a cylindrical structure as a whole, like the damper 70 described in the cited reference 1, but has a constricted shape at the center. The cylindrical upper and lower portions are processed into shapes suitable for damping as the damper 70. For example, the shape is such that a plurality of hemispheres are arranged. The damper 70 is realized by using, for example, rubber as a material. The specific shape and size of the damper 70, the material used for the damper 70, and the like can be arbitrarily selected according to the required elasticity and the limited weight of the damper 70.

  Next, a sectional view when the damper 70 is attached is described on the right side of FIG. First, the center part of the damper 70 is mounted on the auxiliary mounting plate 30. This mounting method will be described with reference to FIG.

  A through hole 71 is formed in the center of the damper 70. Then, a spacer 72 with a flange is inserted into the through hole 71. Further, a washer 73 is placed so as to overlap the flange portion of the flanged spacer 72. Further, the installation position of the spacer 70 is adjusted so that the hole of the through hole 71 is overlapped with the hole of the hole 74 of the mounting plate provided on the basic mounting plate 20.

  In this state, the damper mounting screw 60 is inserted into the center hole of the washer 73, the inside of the flanged spacer 72, and the hole 74 of the mounting plate, so that the damper mounting screw 60 extends to one side of the base mounting plate. Let through. Then, the shaft of the penetrating damper mounting screw 60 is screwed and fastened to the nut 75.

  Thereby, the base mounting plate 20 and the auxiliary mounting plate 30 are fixed via the spacer 70.

  In the above description, the fixing of the base mounting plate 20 and the auxiliary mounting plate 30 has been described. That is, the fixing by the spacer 41 has been described.

  In this regard, when the spacer is the spacer 42, the base mounting plate 20 and the hard disk drive 10 are fixed via the spacer 42. In this case, the auxiliary mounting plate 30 on the right side of FIG. Further, the base mounting plate 20 and the nut 45 on the right side of FIG. 6 are replaced with the hard disk drive 10 and the screw holes provided in the hard disk drive 10, respectively. The hard disk drive 10 is usually provided with a screw hole according to the standard of the hard disk drive 10. For example, in the case of a 3.5-inch hard disk drive, six screw holes are provided on the side surface and four screw holes on the bottom surface, and the screw holes are screwed and fastened to the damper mounting screws 60. You may do it.

  Next, refer to the lower left of FIG. As described in the lower left part of FIG. 6, the diameter of the central portion of the damper 70 is referred to as “first diameter” in the following description. The diameters of the upper and lower portions of the damper 70 will be referred to as “second diameters” in the following description. Also, the length of the first diameter is shorter than the length of the second diameter. Based on these, a method of attaching the center of the damper 70 to the auxiliary attachment plate 30 or the foundation attachment plate 20 will be described with reference to FIG.

  First, the state of FIG. 7A is described in the upper left of FIG. This is a state where the first hole 81 is formed in the auxiliary mounting plate 30. The diameter of the first hole 81 corresponds to the length of the first diameter described with reference to FIG. Here, as described above, the length of the first diameter is shorter than the length of the second diameter. Therefore, even if the first hole 81 is formed in the auxiliary mounting plate 30, the damper 70 cannot be inserted into the hole, so that the damper 70 cannot be mounted on the auxiliary mounting plate 30.

  Next, the state of FIG. 7B is described above the center of FIG. This is a state in which the second hole 82 is formed in the auxiliary mounting plate 30. The diameter of the second hole 82 corresponds to the length of the second diameter described with reference to FIG. Here, as described above, the length of the first diameter is shorter than the length of the second diameter. Therefore, if the first hole 81 is formed in the auxiliary mounting plate 30, the damper 70 can be inserted into the first hole 81. However, since the first hole 81 cannot hold the central concave portion (the portion having the first diameter) of the damper 70, the damper 70 cannot be mounted on the auxiliary mounting plate 30.

  Next, the state of (C) is described in the upper right of FIG. This is a state in which a first hole 81, a second hole 82, and a slide hole 83 are formed in the auxiliary mounting plate 30. The width of the sliding hole 83 is at least as long as the length of the first diameter. A hole is made in this way, and first, only half of the damper 70 is inserted into the second hole 82. Then, the central hollow portion (the portion having the first diameter) of the damper 70 is slid with the sliding hole 83 as it is. Specifically, the central recessed portion (the portion having the first diameter) of the damper 70 is slid to the first hole 81. By doing so, the central recessed portion (the portion having the first diameter) of the damper 70 is held by the first hole 81. Thereafter, the damper 70 can be mounted on the auxiliary mounting plate 30 or the base mounting plate 20 by performing the operation on the right side of FIG.

  The state of (D) is described in the lower left of FIG. This is a state in which a notch 84 is provided at the end of the auxiliary mounting plate 30. The width of the notch 84 is at least as long as the length of the first diameter. The notch 84 is provided in this way, and the central recess (the portion having the first diameter) of the damper 70 is inserted into the notch 84 from the end of the auxiliary mounting plate 30. In this way, the notch 84 holds the central recessed portion (the portion having the first diameter) of the damper 70. Thereafter, the damper 70 can be mounted on the auxiliary mounting plate 30 or the base mounting plate 20 by performing the operation on the right side of FIG.

  In this way, the damper 70 can be attached by performing the above-described steps (C) and (D). In this regard, in the above (C), it is necessary to make a plurality of holes, but in the lower left (D), it is sufficient to provide one notch. However, in the above (C), the damper 70 can be mounted by making a hole at an arbitrary position, but in the lower left (D), the notch 84 needs to be provided from the end of the auxiliary mounting plate 30.

  Further, in each embodiment, the second damper 42 that supports a surface perpendicular to the disk rotation surface of the hard disk drive 10 directly fixes the hard disk drive 10 and the base mounting plate 20 and fixes the disk rotation of the hard disk drive 10. The first damper 41 that supports a surface parallel to the surface fixes the hard disk drive 10 and the base mounting plate 20 via an auxiliary mounting plate 30 that is a sheet metal different from the base mounting plate 20.

  Therefore, compared with the case where the base mounting plate 20 and the hard disk drive 10 are directly connected via the second bumper 42, the hole for fixing the base mounting plate 20 and the first bumper 41 is smaller, and the base mounting The effect that the intensity | strength of the board 20 does not become weak is produced.

  The reason why the size of the hole is small will be described with reference to FIG. (E) is a state in which the fourth hole 85 is formed in the base mounting plate 20. The diameter of the fourth hole 85 corresponds to the length of the diameter of the shaft of the damper screw 60.

  Then, when fixing the hard disk drive 10 and the base mounting plate 20 via the auxiliary mounting plate 30, the damper screw 60 is inserted into the fourth hole 85 as shown on the right side of FIG.

  Here, the diameter of the shaft of the damper screw 60 is shorter than the diameter of the through hole 71 provided inside the damper 70, as shown on the right side of FIG. Therefore, the diameter of the fourth hole 85 is shorter than the diameter of the first hole 81. That is, in (E) as compared with (C) and (D), it is only necessary to make a small hole in the base mounting plate 20, and the hole for fixing the bumper 41 described above can be small, and The effect that the intensity | strength of the board 20 does not become weak is produced.

  Next, another embodiment different from the first embodiment will be described. In the description of each embodiment, a configuration unique to each embodiment will be described, but a description of points common to the first embodiment will not be repeated.

<Second embodiment>
Next, a second embodiment will be described with reference to FIG. Here, FIG. 8 is a diagram illustrating the left side surface of the present embodiment, and is a diagram corresponding to FIG. 5 in the first embodiment.

  Referring to FIG. 8, the length of the long side forming the L-shape of the auxiliary mounting plate 30 is longer than that of the first embodiment. The L-shaped long side of the auxiliary mounting plate 30 is not only fixed to the base mounting plate 20 via the first damper 41 but also further connected to the base mounting plate via the third damper 43. 20. That is, the number of dampers for supporting the auxiliary mounting plate 30 is increasing. Although this is a left side view, one third damper 43 is similarly added to the right side.

  That is, in the first embodiment, the two first dampers 41 support a surface parallel to the disk rotation surface of the hard disk drive 10, and the two second dampers 42 support the disk rotation surface of the hard disk drive 10. Although the vertical surface is supported, in the present embodiment, attention is paid to the fact that the area of the housing portion on the surface parallel to the disk rotation surface of the hard disk drive 10 is larger than the area of the housing portion on the vertical surface. Further, a surface parallel to the disk rotation surface of the hard disk drive 10 is supported by the two third dampers 43.

  Thus, since the hard disk drive 10 can be supported by the six dampers, the vibration can be more effectively prevented than in the first embodiment.

  The method of attaching the third damper 43 to the auxiliary mounting plate 30 is the same as the method of attaching the first damper 41 to the auxiliary mounting plate 30, and a description thereof will be omitted.

<Third embodiment>
Next, a third embodiment will be described with reference to FIG. Here, FIG. 9 is a diagram illustrating the left side surface of the present embodiment, and is a diagram corresponding to FIG. 5 in the first embodiment and FIG. 8 in the second embodiment.

  Referring to FIG. 8, a third damper 43 is added as in the second embodiment. In the present embodiment, the third damper 43 is fixed by the new auxiliary mounting plate 30. The third damper 43 is connected to one side of the new auxiliary mounting plate 30 forming the L-shape, and a hole is provided on the other side. Then, the shaft portion of the damper mounting screw 60 inserted through the sleeve in the second damper 42 is further passed through the hole, and then the shaft portion of the damper mounting screw 60 is inserted into the housing of the hard disk drive 10. Screw into a screw hole provided in the body. Thereby, the base mounting plate 20, the auxiliary mounting plate 30, and the hard disk drive 10 are fixed. Although this is a left side view, the auxiliary mounting plate 30 and one third damper 43 are similarly added to the right side.

  That is, in the first embodiment, the two first dampers 41 support a surface parallel to the disk rotation surface of the hard disk drive 10, and the two second dampers 42 support the disk rotation surface of the hard disk drive 10. Although the vertical surface is supported, in the present embodiment, similarly to the second embodiment, the area of the housing portion of the surface parallel to the disk rotation surface of the hard disk drive 10 is larger than that of the vertical surface of the housing portion. Focusing on the fact that the area is larger than the area, the two third dampers 43 further support a surface parallel to the disk rotation surface of the hard disk drive 10.

  Thus, since the hard disk drive 10 can be supported by the six dampers, the vibration can be more effectively prevented than in the first embodiment.

  The method of attaching the third damper 43 to the auxiliary mounting plate 30 is the same as the method of attaching the first damper 41 to the auxiliary mounting plate 30, and a description thereof will be omitted.

<Fourth embodiment>
Next, a fourth embodiment will be described with reference to FIG. Here, FIG. 10 is a diagram illustrating the left side surface of the present embodiment, and is a diagram corresponding to FIG. 5 of the first embodiment, FIG. 8 of the second embodiment, and FIG. 9 of the third embodiment. is there.

  Referring to FIG. 10, in the present embodiment, the auxiliary mounting plate 30 used in each of the above-described embodiments is omitted, and the first damper 41 does not pass through the auxiliary mounting plate 30 and the base mounting plate 20 and the hard disk drive 10. Directly connected to Although this is a left side view, the auxiliary mounting plate 30 is similarly omitted on the right side, and the first damper 41 is directly connected to the base mounting plate 20 and the hard disk drive 10 without passing through the auxiliary mounting plate 30. Connected.

  This has the effect of eliminating the need for the auxiliary mounting plate 30 and reducing the number of components for realizing the embodiment.

  The method of attaching the first damper 41 to the base mounting plate 20 and the hard disk drive 10 without the intervention of the auxiliary mounting plate 30 is the same as the method of attaching the second damper 42 to the hard disk drive 10 and the base mounting plate 20. Description is omitted because there is.

  In the present embodiment, the effect that the dampers included in the above-described embodiments can dampen the hard disk drive 10 against the vibration generated by the operation of these units during image formation. To play.

  As described above, each of the above-described embodiments is a preferred embodiment of the present invention. However, the scope of the present invention is not limited only to the above-described embodiments, and various embodiments may be made without departing from the spirit of the present invention. Implementation in a modified form is possible.

  For example, the first damper 41, the second damper 42, and the third damper 43 may be the same damper, but may have different shapes and materials. For example, it is considered that a load due to gravity is applied to the second damper 42 disposed below the hard disk drive 10 in the vertical direction among the respective dampers.

  Therefore, it is preferable to use a damper having higher elasticity than the other dampers as the second damper 42. As a result, there is an effect that vibration in the direction perpendicular to the disk rotation surface can be further reduced.

  Further, a damper having a larger limit weight than other dampers may be used as the second damper 42. This is because the second damper 42 disposed below the hard disk drive 10 in the vertical direction has a large gravitational load, and therefore it is preferable that the weight limit is correspondingly large.

  Further, each of the above-described embodiments may be used in an environment where the hard disk drive 10 receives vibration during operation. For example, it may be used inside an image forming apparatus where vibration occurs during printing.

  Further, the hard disk drive 10 and the auxiliary mounting plate 30 in each of the above-described embodiments and each damper may be integrated into a storage device, and the storage device may be distributed as a unit. For example, the hard disk drive 10, the auxiliary mounting plate 30, and each damper are connected to form a storage device. Thus, the number of steps required for mounting on the base mounting plate 20 can be reduced, which is good. For example, the number of man-hours when a service person goes to a customer and attaches a storage device to a device used by the customer may be reduced.

  Further, in each of the above-described embodiments, it is assumed that the disk rotation surface of the hard disk drive 10 is set upright so as to be parallel to the vertical direction as shown in FIG. You may lay down so that a rotating surface may become perpendicular to a perpendicular direction. In this case, if the vibration in the front-rear direction is large in the environment in which each embodiment is installed, each embodiment may be installed so that 42 is located in front or rear. In an environment where each embodiment is installed, if the vibration in the left-right direction is large, each embodiment may be installed so that 42 is located on the left or right.

  INDUSTRIAL APPLICABILITY The present invention is suitable for use in vibration damping of a hard disk drive. In particular, it is suitable for use in image stabilization inside an image forming apparatus, which is a device that involves vibration when a hard disk drive is used.
