Description

  The present invention relates to an information storage device that is detachably attached to an information processing device such as a personal computer.

  This type of information storage device, for example, a hard disk drive device (hereinafter referred to as HDD), is built in an information processing device such as a personal computer, and writes data and programs or reads recorded data and the like. It plays an important role as a recording / reproducing apparatus.

  By the way, this HDD is not only built in a main body of an information processing apparatus or the like, but is also considered to be used as a so-called detachable expansion device that is detachable from the information processing apparatus main body.

  The HDD is removed from the information processing apparatus main body as necessary, and is carried by the HDD alone, stored separately from the information processing apparatus main body, or used in other electronic devices. Furthermore, it is used by being mounted on a portable device.

  As such an HDD, there has been proposed an HDD in which the drive mechanism is housed in a housing so as to be portable.

  In such a cartridge-type HDD, if it is accidentally dropped when it is carried as described above, there is a risk of damaging data and media due to the impact at the time of dropping.

Therefore, conventionally, the housing of the HDD is housed in the outer housing, and shock is absorbed by providing a cushioning material between the housing of the HDD and the outer housing. (For example, refer to Patent Document 1).
JP 2004-127438 A

  However, in the past, since the buffer material was only provided at the corners and side surfaces of the HDD housing, a sufficient buffering effect could not be obtained, and data and media damage were reliably prevented. In addition, when a large impact is received, there is a problem that the housing is distorted or the cushioning material becomes unstable.

  Note that the cushioning effect can be enhanced by using a soft and thick cushioning material. In this case, however, the clearance between the HDD housing and the outer housing must be increased. It must be enlarged. Recently, there is a demand for downsizing, the clearance between the HDD housing and the outer housing cannot be increased, and the cushioning material is thin and hard. When the cushioning material is hard, it is difficult to displace, especially when the HDD is lightweight, the cushioning material is difficult to displace, and the necessary cushioning effect cannot be obtained.

  In addition, it is conceivable to increase the buffering effect by providing a cushioning material not only at the corners and side portions of the HDD housing but also at the top surface of the housing. There are many weak parts, and when a shock absorbing material is provided in such a part, there is a possibility that distortion will occur in the case if a large impact is applied.

  In addition, it is conceivable to cover the entire surface of the HDD housing with a buffer material, but in this case, it becomes difficult to displace compared to the case where the buffer material is dispersed and arranged, especially when the HDD is lightweight. In such a case, a sufficient buffering effect cannot be obtained.

  The present invention has been made by paying attention to the above circumstances, and the object of the present invention is to stably obtain a sufficient buffering effect even when subjected to a large impact or light weight. An information storage device is provided.

  In order to solve the above-described problem, the first aspect of the present invention includes a first housing containing a plurality of hard parts constituting the information storage unit, and a second housing that accommodates the first housing inside. A body, a first buffer member provided at a corner of the first housing, and a plurality of second buffers provided on the hard part on the surface of the first housing. And a buffer means for supporting the first casing in a state of being separated from the second casing.

  According to the present invention, a sufficient shock-absorbing effect can be obtained stably even when subjected to a large impact or light weight.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is a perspective view showing an inner casing (first casing) 2 according to an embodiment of the present invention.

  Inside the inner casing 2 is housed a hard disk drive mechanism section that constitutes an information storage section described in detail later.

  As shown in FIG. 2, the inner casing 2 is housed in an outer casing 3 as a second casing to constitute a cartridge type information storage device 1.

  This information storage device 1 can be used as an expansion device for capacity expansion or as a recording medium for recording a large amount of data and programs such as images and videos without using a cable or the like for a personal computer or a video camera. It is detachably connected directly by a connector (not shown).

  A cap-shaped buffer member (first buffer member) 11 is disposed at a square corner of the inner casing 2, and the inner casing 2 is supported in the outer casing 3 via the buffer member 11.

  As shown in FIG. 3, the inner housing 2 includes a chassis 4A and a top cover 4B, and a hard disk drive mechanism 9 is housed in a space formed between the chassis 4A and the top cover 4B. .

  The hard disk drive mechanism 9 includes a magnetic disk 6 mounted on the rotary spindle 5, a magnetic head 7 as an information processing head for recording / reproducing information on the magnetic disk 6, and the magnetic head 7 on one end side. And a head arm 8 to be supported.

  Further, on the back side of the chassis 4A, a wiring board 10 on which an electronic circuit for controlling drive control of each component described above and recording / reproduction to / from the magnetic disk 6 is mounted by a screw 20 is further installed as a built-in component. The filter 21 is attached by screws 22 as hard parts. The wiring board 10 includes a spindle motor (first drive motor) 12 as a hard part for rotating the rotary spindle 5 and a carriage motor (second drive motor) 13 as a hard part for rotating the head arm 8. Is attached. On the wiring board 10, connector pins (not shown) for inputting / outputting recording / reproducing signals to / from the magnetic head 7 and driving power sources for the spindle motor 12 and the carriage motor 13 are located on one side of the chassis 4 </ b> A. Attached.

  By the way, in this embodiment, a plurality of protruding buffer members (second buffer members) 15, 16, and 17 are disposed on the surface side of the chassis 4A constituting the inner housing 2. . These buffer members 15, 16, and 17 are formed of, for example, a rubber material. In addition, as a protrusion shape of the buffer members 15, 16, and 17, a mountain shape, a triangular pyramid, a hemispherical shape, or the like can be considered.

  The buffer member 15 is affixed to be positioned on the substrate surface portion of the spindle motor 12, the buffer member 16 is affixed to be positioned on the substrate surface portion of the carriage motor 13, and the buffer member 17 is the head of the fixing screw 22. Affixed to the part.

  That is, the inner casing 2 is supported by the buffer member (first buffer member) 11 in the outer casing 3 and also by a plurality of buffer members (second buffer members) 15, 16, and 17. Stored.

  Therefore, when the information storage device 1 is carried around, the shock acting on the inner housing 2 from the outer housing 3 when the information storage device 1 is accidentally dropped is absorbed by the buffer member 11. Of course, it is absorbed by the plurality of buffer members 15, 16, and 17, and the failure of the information storage device 1 can be reliably prevented.

  Further, since the plurality of buffer members 15, 16, and 17 are attached to the hard parts (spindle motor 12, carriage motor 13, fixing screw 22) in the inner housing 2, the buffer members 15, 16, and 17 are attached. The impact transmitted through the can be received by hard parts, and there is no possibility of damaging the inner housing 2.

  Further, since the shock is received by the plurality of buffer members 15, 16, and 17, the buffer members 15, 16, and 17 are easily displaced as compared with the case where the inner casing 2 is entirely covered with the buffer material. Even when the housing 2 is light, it is possible to absorb the impact well.

  In addition, since the plurality of buffer members 15, 16, and 17 are formed in a protruding shape, they are more easily deformed with respect to an impact and can be satisfactorily absorbed.

  FIG. 4 is a side view showing another mounting structure of the cushioning material.

  In the first embodiment described above, the cushioning materials 15 to 17 are individually and directly attached to the hard parts of the inner housing 2, but in the case shown in FIG. 36 is affixed to the inner housing 2 by attaching 36 on a thin sheet 37 such as PET.

  FIG. 5 is a side view showing still another attachment structure of the cushioning material.

  In the example shown in FIG. 5, a plurality of buffer members 31 to 36 are integrated by a thin buffer material 38 and attached to the inner housing 2.
