Description

  The present invention relates to a recording / reproducing apparatus incorporated in an electronic device, particularly a portable electronic device.

  Electronic devices are becoming lighter and smaller, and in recent years, portable electronic devices that can be used outdoors by individuals, such as game devices and mobile phones, have been widely used. When a user operates such an electronic device, a recording / reproducing apparatus capable of storing operation contents may be incorporated in the electronic device.

  On the other hand, with the progress of portability, countermeasures against vibrations and shocks are required, so that countermeasures are required not only for the electronic device body but also for the recording / reproducing apparatus. 2. Description of the Related Art Conventionally, hard disk drives (hereinafter referred to as HDDs) are known as recording / reproducing devices that are particularly vulnerable to vibrations and shocks (hereinafter collectively referred to as disturbances). Patent Document 1 is known as an example of improving the impact resistance of the HDD.

Patent Document 1 includes a housing for housing an HDD and fixing the HDD with bolts, and a protective box for housing the housing. The inner surface and the housing of the protective box are a support receiving member and the support It is disclosed that the resistance of the HDD against a drop impact can be realized by a configuration in which elastic engagement is performed by independent elastic members having an area smaller than the area of the receiving member.
JP-A-10-222972

However, the elastic body disclosed in Patent Document 1 has the following problems.
(1) Since the HDD and the housing are screwed and fixed with bolts, when the housing is subjected to disturbance and the housing is twisted and / or distorted, vibration due to the restoring force that restores the deformation is In some cases, the magnetic field propagates to the housing via the receiving member and the elastic member, and the recording / reproducing characteristics of the HDD are adversely affected by the vibration propagated to the housing.
(2) The elastic member that elastically engages the protective box and the housing is much smaller than the area of the support receiving member, and is elastically supported only at each corner of the support receiving member. When receiving a disturbance, the support receiving member existing in the gap between the elastic members is distorted, and the built-in HDD may be abnormal in recording / reproducing characteristics due to the distortion.
(3) In recent years, HDDs have been increasingly increased in capacity and miniaturized, and HDDs of 3.5 mm or 2.5 mm to less than 2 mm have been developed and put on the market. However, in the configuration disclosed in Patent Document 1, the impact buffering configuration is large, so that the advantage of a small HDD of less than 2 mm, such as 1.8 mm, is lost, and the electronic equipment incorporating the HDD is also increased in size after all. I had to do it.
(4) In addition, since there are very few engaging portions that directly elastically engage a small HDD of less than 2 mm, it was one reason that HDDs of less than 2 mm originally developed for portable use could not be used.

  An object of the present invention is to provide a compact recording / reproducing apparatus with further improved impact resistance.

  The recording / reproducing apparatus of the present invention that solves the above problems includes a disk drive, a storage member that stores the disk drive via an elastic member that is elastically engaged with the disk drive, and an upper box that stores the storage member. A box composed of a lower box, and when the upper box and the lower box are assembled into the box, the upper main surface of the upper box and the lower main of the lower box facing each other The surface and the storage member are elastically engaged with each other through an upper surface impact absorbing member and a lower surface impact absorbing member that are in close contact with each other in a planar shape, and the box body extends from the upper main surface and the lower main surface. The side surface and the storage member are configured to be elastically engaged via side impact absorbing members that are in close contact with each other in a planar shape.

  By providing the above configuration, it is excellent in resistance to disturbance, and the impact absorbing member can be easily attached and detached even when the recording / reproducing apparatus needs to be repaired.

As the impact absorbing member that elastically engages between the storage member and the box in the present invention, for example, a flexible polyurethane foam, an acrylic foam, or the like can be applied, and the density of the elastic member is 0.06 g / cm ^{3 to} 0. .24 g / cm ³ is preferred. The thickness varies depending on the weight of the recording / reproducing apparatus, but is preferably 5 mm or more.

  Next, the best embodiment of the recording / reproducing apparatus of the present invention will be described with reference to the drawings. In the following embodiments, a hard disk drive having a width of 54 mm, a length of 78.5 mm, and a height of 8 mm will be described as an example of a recording / reproducing apparatus. However, the recording / reproducing apparatus of the present invention is limited to a hard disk drive. However, the present invention can be applied to a recording / reproducing apparatus using a disc-shaped information medium.

  Next, a configuration in which the hard disk drive is housed in the housing member 1 will be described with reference to FIG. In the figure, reference numeral 5 denotes a hard disk drive, and a hard disk drive (hereinafter referred to as HDD) 5 is a 1.8 mm diameter hard disk, a head for transmitting / receiving an information signal to the hard disk, a spindle motor for rotating the hard disk, etc. , The lower surface 5b and the side surface 5c, and electrode terminals 5d for transmitting / receiving information signals transmitted / received by the head to the outside. 6 is an elastic member that elastically engages the HDD 5 with respect to the storage unit 1. In this embodiment, the inner member is approximately rectangular of 53.7 mm and 80 mm, and a rubber hardness of 40 ° with a height of 9 mm is applied. On the inner surfaces of the short side surface 6a and the long side surface 6b that are in close contact with the surface 5c, and in the form of a short bottom surface 6c and the long bottom surface 6d that are in close contact with the lower surface 5b of the opposing surface of the upper surface 5a. Is composed of side surface engaging portions 6f and 6l along the outer peripheral shape of the side surface 5c and the upper surface 5a, and a terminal contact portion 6e that receives the electrode terminal 5d from below. Reference numerals 11 and 12 denote a storage unit upper side and a storage unit lower side constituting the storage unit 1, respectively. The storage unit upper side 11 is composed of an upper main surface 11a and a side surface 11c. In the present embodiment, the upper main surface 11a has a through hole 11b. The storage portion lower side 12 is composed of a lower main surface 12a and a side surface 12c. In the present embodiment, the lower main surface 12a has a through hole 12b as well as the upper main surface 11a. Further, the side surfaces 11c and 12c are provided with engaging portions 11d and 12d for engaging the storage portion upper side 11 and the storage portion lower side 12, respectively.

  That is, the HDD 5 and the elastic member 6 are in close contact with each other at the side surface engaging portions 6f and 6l matching the shape of the side surface 5c of the HDD 5, and at the same time, the outer peripheral surface of the lower surface 5b of the HDD 5 is the short bottom surface 6c and the long bottom surface 6d. Adhere closely to the surface. The elastic member 6 that elastically engages with the HDD 5 is housed inside the storage unit upper side 11 and the storage unit lower side 12, and is formed on each of the side surface 11 c of the storage unit upper side 11 and the side surface 12 c of the storage unit lower side 12. The storage member 1 is configured by engaging the engaging portions 11d and 12d. In the present embodiment, the engaging portion 11d is a through hole, and is configured by a key-like engaging portion 12 that is locked to the hole of the engaging portion 11d. Further, the distance between the short side surface 6a and the long side surface 6b of the elastic member 6 in the present embodiment is configured to be longer than the internal thickness of the storage member 1, and the short side surface 6a and the long bottom surface 6d to the short side surface 6a and When the elastic member 6 is stored in the storage member 1 by configuring the distance to each contact surface where the long side surface 6b contacts the upper surface 11a to be longer than the distance of the surface 5b which is the upper surface 5a of the HDD 5, The short side surface 6a and the long side surface 6b are pressed by the upper main surface 11a, and the adhesion between the HDD 5 and the storage member 1 and the elastic member 6 is further improved by pressing deformation.

The housing member 1 housing the HDD 5 in this way inserts the side impact absorbing member 2c into the housing portion 1 while inserting the drive terminal 5e protruding from the electrode terminal 5d into the terminal penetration portion 2d shown in FIG. Then, the upper surface impact absorbing member 2a and the lower surface impact absorbing member 2b are engaged with the side surface impact absorbing member 2c, and the impact absorbing member 2 including the storage portion 1 shown in FIG. 3 is assembled. In the present embodiment, as the impact absorbing member 2, the upper impact absorbing member 2a and the lower impact absorbing member 2b are plate-like having a width of 57 mm, a length of 84 mm, and a thickness of 5 mm, and the side impact absorbing member 2c has an outer peripheral width of 84 mm and an outer peripheral length of 57 mm. A urethane foam having a height of 18 mm, a cavity having a thickness of 5 mm from the outer periphery, and a density of 0.06 g / cm ³ and a thickness of 5 mm was used. Further, in the present embodiment, as shown in the figure, the upper surface impact absorbing member 2a in a state including the storage portion 1 protrudes from the side impact absorbing member 2c, and the upper surface impact absorbing member 2a and the side impact absorbing member 2c are free of play. It has a configuration with an insertion distance. Although not shown, the lower impact absorbing member 2b also protrudes from the side impact absorbing member 2c, and both the lower impact absorbing member 2b and the side impact absorbing member 2c have a loose insertion distance.

  The manner in which the shock absorbing member 2 assembled in this way is housed in the upper lid 3 and the lower lid 4 as shown in FIG. 1 will be described with reference to FIG. The upper lid 3 is basically composed of an upper lid upper surface 3b and an upper lid side surface 3d. In this embodiment, the upper lid upper surface 3b is provided with a through hole 3c, and the upper lid side surface 3d is provided with an engaging portion 3a. The lower lid 4 is basically composed of a lower lid lower surface 4b and a lower lid side surface 4d, and similarly to the upper lid 3, the lower lid lower surface 4b is provided with a through hole 4c, and the lower lid side surface 4d is associated with the upper lid 3. An engagement portion 4a that engages with the joint portion 3a is provided. In the present embodiment, the depth of the lower lid 4 is configured to be deeper than the depth of the upper lid 3, but the depth relationship is not limited to this embodiment. However, it is preferable to construct the lower lid 4 deeply as in the present embodiment, since the shock absorbing member 2 can be once stably stored in the lower lid 4 during assembly. After the shock absorbing member 2 is housed in the lower lid 4, the upper lid 3 is covered, and the engaging portion 3 a provided on the upper lid side surface 3 d is engaged with the engaging portion 4 a provided on the lower lid side surface 4 d, and the recording / reproducing apparatus of this embodiment Finish making. In the present embodiment, the upper lid side surface 3d is engaged with the outer side of the lower lid side surface 4d, the engaging portion 4a provided in the lower lid 4 is configured by a through hole formed in the lower lid side surface 4d, and the engaging portion 3a is The upper lid 3 and the lower lid 4 are locked by engaging the L-shaped engaging portion 3a and the through-hole engaging portion 4a. The configuration. Further, before the locking by the engaging portions 3a and 4a, the thickness of the shock absorbing member 2 is longer. When the engaging portions 3a and 4a are locked, the upper surface shock absorbing member of the shock absorbing member 2 is locked. 2a and the bottom impact absorbing member 2b are pressed and flattened by pressing, thereby changing the loose insertion relationship between the top impact absorbing member 2a and the bottom impact absorbing member 2b and the side impact absorbing member 2c into a fitting relationship. .

  As described above, in this embodiment, the HDD 5 is held by the elastic engagement that is in surface contact with the storage member 1, and the storage member 1 is also held by the elastic engagement that is in surface contact with the upper lid 3 and the lower lid 4. Since it is formed with a completely flexible structure, even when a disturbance is received, the shock resistance can be improved by buffering the disturbance in a plane. Also, the elastic engagement between the HDD 5 and the storage member 1 via the elastic member 6 is such that the upper surface 5a of the HDD 5 is not provided with the elastic member 6, and is engaged with the outer peripheral portion of the lower surface 5b only by the short bottom surface 6c and the long bottom surface 6d. By doing so, since it is not elastically engaged with the parts where the main parts that directly affect the recording / reproducing of the HDD 5 such as the spindle motor and the head are arranged, the influence of the elastic engagement on the recording / reproducing characteristics of the HDD 5 is also eliminated. be able to.

  In the above embodiment, the side impact absorbing member 2c is integrated. However, as shown in FIG. 5, the impact absorbing member may be made independent of each surface constituting the storage member 1. That is, as shown in the figure, the shock absorbing member 7 has an upper surface impact absorbing member 7a that is in close contact with the upper main surface 11a in a surface shape, and a lower surface impact absorbing member 7b that is in close contact with the lower main surface 12a in a surface shape. The long side impact absorbing member 7c, the short side impact absorbing member 7d and the terminal side impact absorbing member 7e which are in close contact with the side surfaces 11c and 12c in a planar shape. The material and thickness of the shock absorbing member 7 are the same as those of the shock absorbing member 2, the long side shock absorbing member 7c is 94 mm long and 18 mm high, the short side shock absorbing member 7d is 56 mm long and 18 mm high, and the terminal. The side-surface impact absorbing member 7e was 9 mm long and 18 mm high. In the configuration of the shock absorbing member 7, since it can be independently engaged with the side surfaces (side surfaces 11 c and 12 c) of the storage unit 1 in a planar shape, compared with the side impact absorbing member 2 c of the shock absorbing member 2, Since the step of attaching the storage member 1 to the side impact absorbing member 2c while inserting the drive terminal 5e into the terminal penetration portion 2d can be omitted, a simple configuration can be realized. Although not shown, the intermediate configuration between the side impact absorbing member 2 and the side impact absorbing member 7, that is, the long side impact absorbing member 7c, the short side impact absorbing member 7d, and the terminal side side impact absorbing member 7e are integrated. It may be a structured.

  On the other hand, heat is generated from the spindle motor due to, for example, the high-speed rotation of the hard disk built in the HDD 5. In order to dissipate this heat generation, through holes 11b and 12b are provided in the upper main surface 11a and the lower main surface 12a for housing the HDD 5, respectively. However, in order to radiate heat through the through holes 11b and 12b, in the shock absorbing members 2 and 7, the upper surface shock absorbing members 2a and 7a and the lower surface shock absorbing members 2b and 7b are formed of flat plates. The road is blocked. FIG. 6 shows a configuration that can eliminate such interruption of the heat dissipation path.

  FIG. 2 is an exploded perspective view of another embodiment of the recording / reproducing apparatus of the present invention. The shock absorbing member 8 that closely contacts and engages the storage member 1 with the upper lid 3 and the lower lid 4 has an upper surface. The impact absorbing member 8a, the lower surface impact absorbing member 8c, the long side impact absorbing member 8e, the short side impact absorbing member 8f, and the terminal side impact absorbing member 8l are basically configured in the same manner as in FIG. The center part of each of the lower surface impact absorbing member 8c includes an upper surface through hole 8b and a lower surface through hole 8d. The material and thickness of the shock absorbing member 8 are the same as those of the shock absorbing member 2. The upper surface through hole 8b and the lower surface through hole 8d were each 44 mm wide and 70 mm long. As shown in FIG. 7, the impact absorbing member 8 has a long side impact absorbing member 8 e, a short side impact absorbing member 8 f, and a terminal side side impact absorbing member 8 l in close contact with the side surface of the storage member 1. Thereafter, the upper surface impact absorbing member 8a and the lower surface impact absorbing member 8c are brought into close contact with each other in a planar shape to obtain the configuration shown in FIG. As shown in FIG. 8, heat is radiated through the through hole 8b provided in the center of the upper surface impact absorbing member 8a and the through hole 8d provided in the center of the lower surface impact absorbing member 8c (not shown). Since it connects with the upper cover through-hole 3c of the upper cover 3 shown in 4 and the lower cover through-hole 4c of the lower cover 4, high heat dissipation efficiency is realizable.

  In the case where the side impact absorbing member 2c has an independent configuration as shown in FIGS. 5 and 6, there is a problem that it is difficult to engage the side impact absorbing member with the storage member 1. For example, as shown in FIG. If the intermediate storage member 9 is provided, this problem can also be solved. This figure shows an example in which the intermediate storage member 9 is provided between the upper surface impact absorbing member 8 a and the upper lid 3. For example, the intermediate housing member 9 is placed on the upper lid 3, the upper surface impact absorbing member 8 a is housed in the intermediate housing member 9, and then the housing member 1 is placed on the upper surface impact absorbing member 8 a. The long side impact absorbing member 8e, the short side impact absorbing member 8f, and the terminal side impact absorbing member 8l are inserted, the lower surface impact absorbing member 8c is placed, and then the lower lid 4 is placed, and the upper lid engaging portion 3a. The lid engaging portion 4a is engaged. In the present embodiment, the intermediate storage member 9 is described as an example in which the opening is directed to the lower lid 4 side. However, the intermediate storage member 9 includes the long side impact absorbing member 8e, the short side impact absorbing member 8f, and the terminal side impact. When the area when each of the absorption members 8l is engaged with the storage member 1 is larger than the opening area of the opening of the intermediate storage member 9, the lower cover after the bottom cover 4 is assembled with the upper cover 3 rather than the lower cover 4 having a deep bottom. This is because it is easier to assemble 4 and the direction of the opening in the intermediate storage member 9 is not limited to this embodiment.

  Further, in FIG. 10, since the intermediate storage portion 9 abuts against the drive terminal 5e, the wiring (not shown) connected to the drive terminal 5e needs to be bent in the thickness direction of the intermediate storage portion 9. For example, FIG. As described above, the configuration of the intermediate housing member 10 that can position only the terminal-side side impact buffer member 81 can improve the degree of freedom of wiring connected to the drive terminal 5e.

  In the above-described embodiment, the elastic member 6 that elastically engages the storage unit upper side 11 and the storage unit lower side 12 is applied as the storage unit 1, and the impact absorbing members 2, 7 that elastically engage the storage unit 1 in a planar shape 8 is described, for example, by forming the short side surface 6a and the long side surface 6B of the elastic member 6 so as to extend along the substantially Ω-shaped side surface of the upper surface 5a of the HDD 5, the storage unit 1 The storage unit upper side 11 and the storage unit lower side 12 can be omitted. Further, for example, the side impact absorbing member 2c, the long side impact absorbing members 7c and 8e, the short side impact absorbing members 7d and 8f, etc. It is possible to directly store the HDD in the shock absorbing member by following the substantially Ω-shaped side surface of the upper surface 5a. By adopting any one of these configurations, the number of parts can be further reduced in size and thickness. Can also be reduced The

  In the above-described embodiment, a 1.8-inch hard disk drive is described as an example of the disk drive, but the present invention can be applied without depending on the size of the disk. Further, for example, a slot-in type replaceable disk drive can be applied to a disk drive other than the hard disk drive.

  As described above, the recording / reproducing apparatus of the present invention has a configuration in which the elastic member interposed between the disk drive and the storage member and the shock absorbing member interposed between the storage member and the box are elastically supported in a planar shape. The received disturbance is diffused in a planar shape, so that local impacts such as distortion and twist can be eliminated, and the disturbance resistance can be remarkably improved.

  In addition, since the elastic member and the impact absorbing member have a planar shape and are elastically engaged, for example, when it is necessary to disassemble the recording / reproducing apparatus of the present invention due to the life of the disk drive, etc., the box and the storage member Since only the disk drive can be taken out simply by releasing the engagement of the respective engaging portions, the repair can be performed very easily.

  Since the recording / reproducing apparatus of the present invention is excellent in impact resistance, it can be applied to a wide range of fields such as a camera-integrated video, a navigation system, and a notebook computer.
