Description

  The present invention relates to a DVD recorder with a built-in hard disk drive, and more particularly to a mounting structure for mounting a hard disk unit including a hard disk drive.

  Currently, in many electronic devices such as audio equipment and video equipment, optical disk media and tape media are employed as recording media. The electronic device includes a hard disk drive with a large storage capacity, and is used as a temporary storage device before recording on a recording medium.

  The hard disk drive contains a plurality of metal disks and rotates at a high speed. The hard disk drive is provided with a motor for rotational driving, and the motor rotates at high speed. The hard disk drive vibrates not a little due to the rotation of the metal disk and the rotation of the motor.

  FIG. 4 is a perspective view of a hard disk mounting structure provided in a conventional optical disk apparatus. As shown in FIG. 4, a support plate 92 is attached to the lower surface of the hard disk drive 91 with bolts. A support base member 93 having leg portions 931 fixed to the chassis of the optical disk apparatus (not shown) is provided, and the support plate 92 and the support base member 93 are connected by bolts. An anti-vibration rubber 94 is arranged between the support base member 93 and the vibration of the hard disk drive 91 from being transmitted to the support base member 93.

  Further, a ground plate 95 that is partly elastically deformable is attached to the support base member 93. The support base member 93 is grounded by coming into contact with the casing, and even if the hard disk drive 91 vibrates, the elastic deformation portion of the ground plate 95 always contacts the support plate 92 and is grounded.

  However, the hard disk drive 91 is heavy, and there is a case in which the ground plate 95 that is in contact with the hard disk drive 91 by an elastic force is damaged.

  Therefore, in the device described in Japanese Utility Model Registration No. 3089613, a concave step portion recessed downward to come into contact with the ground pattern is formed at a position of the top plate facing the ground pattern portion of the substrate. It is shown.

  In the invention described in Japanese Patent Laid-Open No. 2002-223084, a plurality of jumper wires penetrating the substrate and soldered to the ground pattern on the ground pattern surface side and drawn to the component placement surface side are provided. It is provided on a substrate, and a steel plate chassis formed with a convex portion that is pushed and bent by a predetermined height toward the substrate side and is in contact with a jumper wire is shown.

The upper surface cover Cv engages with the upper portion of the chassis Ch, and the side surface is fixed to the chassis Ch using the bolts Bt.

  After the upper surface cover Cv is fixed to the chassis Ch, the front panel Fp is engaged from the front side of the chassis Ch. A door Fp1 that can be opened and closed is formed on the front panel fp, and a disk tray (not shown) for placing an optical disk provided in the DVD recorder unit Dr enters and exits through the door Fp1 to insert (load) the optical disk. Or discharge (unloading).

  As shown in FIG. 2, the hard disk unit 1 supports the hard disk drive 11, the first support member 12 fixed to the bottom surface of the hard disk drive 11, the first support member 12, and contacts the rear panel 2. A second support member 13 fixed to the chassis Ch and an anti-vibration cushion 14 for preventing the vibration of the hard disk drive 11 from propagating to other places are provided.

  As shown in FIG. 3, the hard disk drive 11 is provided with a female screw hole 111, and is fastened together with the first support member 12 using a first bolt Bt <b> 1. The hard disk drive 1 is provided with a control unit for controlling the rotational speed and pickup of a metal disk arranged inside, and for exchanging recorded or read data. It is grounded using a metal exterior. The metal exterior portion and the first support member 12 are in contact with each other. The first support member 12 also has a rectangular shape, and includes a screw hole 121 through which the first bolt Bt1 passes and through holes 122 formed at four corners.

  As shown in FIGS. 2 and 3, the second support member 13 includes a main body portion 131, a leg portion 132 that extends downward from the main body portion 131 and is fixed to the chassis Ch, and a contact portion that contacts the rear panel 2. 133. The main body 131 has a rectangular shape, and through holes 134 through which the second bolts Bt2 are penetrated are formed at the four corners.

  The first support member 12 to which the hard disk drive 11 is fixed is connected using the second bolt Bt2, and the second bolt Bt2 is penetrated from the first support member 12 side, and the through hole of the second support member A nut Nt is screwed and fastened to a tip portion that penetrates through 134. An anti-vibration cushion 14 is attached to the bolt Bt2.

  As shown in FIG. 3, the anti-vibration cushion 14 has a shape in which a barrel-shaped first anti-vibration member 141 and a second anti-vibration member 142 are connected in the axial direction, and the first anti-vibration member 141 is the first anti-vibration member 141. The first support member 12 and the head Bt21 of the second bolt Bt2 are disposed, and the second vibration isolation member 142 is disposed between the first support member 13 and the second support member 13.

  The first support member 12 shown in FIG. 2 and FIG. 3 has the vibration-proof cushion 14 inserted through the through-hole 122, but is not limited thereto, and the through-hole 122 of the first support member 12 is not limited thereto. It may be formed in a concave shape opened to the side. In this case, when the vibration-proof cushion 14 is attached to the through-hole 122, it is easy to attach and the assembly is facilitated.

  Thus, by arranging the vibration-proof cushion 14, vibration generated in the hard disk drive 11 and propagated to the first support member 12 is transmitted to the second support member 13 via the second bolt Bt 2 and / or directly. It is possible to suppress transmission. Thereby, it is possible to suppress the vibration from being propagated to the chassis Ch and the rear panel 2 on which the second support member 13 is fixed or in contact with each other. Connector) can be prevented from being damaged.

  As shown in FIG. 3, the rear panel 2 is provided with a hook portion 21 formed by cutting and raising. The hook portion 21 includes a connection portion 211 whose tip is broken into two (see FIG. 2). The hook portion 21 is formed so as to pass through the opening 135 formed in the contact portion 133 of the second support member 13. The hook portion 21 penetrating the opening 135 is disposed so that the connection portion 211 overlaps the through hole 122 of the first support member 12. The connection portion 211 is disposed between the first support member 12 and the first vibration isolation member 141, and the second bolt Bt <b> 2 penetrates between the bifurcated portions at the tip of the connection portion 211. The connection portion 211 can be stably brought into contact with the first support member 12 by being pushed by the first vibration isolation member 141.

  Further, although the connection portion 211 is not firmly fixed to the first support member 12, it is in contact with the first support member 12 by being stably pressed by the first vibration isolation member 141, and thus the hard disk drive 11. The transmission of the vibration generated and propagated to the first support member 12 to the connection portion 211 is suppressed. Furthermore, since the connecting portion 211 is electrically connected to the metal exterior of the hard disk drive 11 via the first support member 12, the hard disk drive 11 can be grounded stably.

  As a result, the hard disk drive 11 can be stably grounded without attaching an elastically deformable metal grounding member that electrically connects the second supporting member 13 and the first supporting member 12 conventionally used. Can reduce the cost. Further, since the hard disk drive 11 is heavy, the grounding member has a heavy burden and is easily damaged. However, since the grounding member itself can be omitted, the grounding member may be damaged or deformed. The number of times can be reduced.

  In the above embodiment, the hook portion 21 is formed integrally with the rear panel 2 as an example. However, the hook portion 21 may be manufactured separately and attached later. Further, the connection portion 211 of the hook portion 21 may be disposed between the second vibration isolation member 142 and the first support member 12.
