  As described above, the mounting plate 34 is formed with a screw hole 34a into which the screw 24 for fixing the HDD cover 20 is screwed and a screw hole 34b into which the screw 26 for fixing the memory cover 22 is screwed. . The screw holes 34a and 34b are formed by burring the mounting plate 34 made of a metal plate, and the burring portion protrudes from the back side of the mounting plate 34 as shown in FIG. Although not appearing in FIG. 7, the two burring portions are close to each other and protrude from the back side of the mounting plate 34 corresponding to the screw holes 34 a and 34 b. A burring part is an example of a protrusion part.

  On the other hand, the width of the slit 44 into which the attachment plate 34 is inserted is slightly larger than the thickness of the attachment plate 34, and the burring portion insertion portion 44a, which has a width that allows each of the two burring portions to be inserted. 44b is provided. Therefore, the mounting plate 34 cannot be inserted into the slit 44 until the burring portions of the screw holes 34 a and 34 b are aligned with the burring portion insertion portions 44 a and 44 b of the slit 44.

  FIG. 8 is a plan view showing a state in which the hard disk device 30 is arranged in the HDD accommodating portion 40. FIG. 9 is a cross-sectional view taken along line IX-IX in FIG.

  When the burring portions of the screw holes 34a and 34b of the mounting plate 34 are aligned with the burring portion insertion portions 44a and 44b of the slit 44 and then the mounting plate 34 is inserted into the slit 44, as shown in FIG. When the leading end hits the abutting portion 12 c of the slit 44, the hard disk device 30 can no longer be moved. When the hard disk device 30 is in this position, the connector of the hard disk device 30 and the connector 42 of the HDD housing unit 40 are aligned.

  Here, the position of the hard disk device 30 in the height direction (upper direction in the drawing in FIG. 9) is generally determined by inserting the attachment plate 34 into the slit 44. Further, the position of the hard disk device 30 in the horizontal direction (left and right direction in FIG. 8) is determined by the front end of the mounting plate 34 coming into contact with the abutting portion 12 b (part of the housing 12) located behind the slit 44. Further, the position of the connector in the insertion direction (vertical direction in FIG. 8) is determined by aligning the two burring portions of the mounting plate 34 with the burring portion insertion portions 44 a and 44 b of the slit 44.

  As described above, the hard disk device 30 is inserted into the slit 44 provided in the housing 12 by inserting the mounting plate 34 extending from the side of the hard disk device 30 into the first position (connector) in the HDD housing portion 40. Can be arranged at positions aligned.

Thereby, the connector of the hard disk device 30 can be reliably connected to the connector 42 of the HDD accommodating portion 40, and damage to the connector at the time of connection can be prevented.

  FIG. 10 is a plan view showing a state in which the connector of the hard disk device 30 is connected to the connector 42 of the HDD accommodating portion 40. 11 is a cross-sectional view taken along line XI-XI in FIG. 12 is a cross-sectional view taken along line XII-XII in FIG.

  As shown in FIG. 10, a cover placement portion 12 c (a part of the housing 12) extends above the slit 44, and a through hole 28 a into which the screw 24 for fixing the HDD cover 20 is inserted, and A through hole 28b into which a screw 26 for fixing the memory cover 22 is inserted is formed.

  When the hard disk device 30 is moved and the connector is completely connected to the connector 42 of the HDD housing portion 40, the screw holes 34a of the mounting plate 34 are aligned with the through holes 28a of the cover mounting portion 12c, as shown in FIG. It becomes. Further, the screw holes 34b of the mounting plate 34 are aligned with the through holes 28b of the cover mounting portion 12c. If the position of the hard disk device 30 at this time is the second position, the slit 44 is formed when the hard disk device 30 is in the first position from the position of the mounting plate 34 when the hard disk device 30 is in the first position. It extends to the position of the mounting plate 34.

  When the HDD cover 20 is placed on the HDD housing portion 40, the screw through holes of the HDD cover 20 are aligned with the through holes 28a of the cover mounting portion 12c, so that the screw through holes and the cover mounting portion of the HDD cover 20 are aligned. The screw 24 can be screwed into the screw hole 34a of the mounting plate 34 through the through hole 28a of 12c. As a result, the HDD cover 20 can be fixed (coupled) to the casing 12 and the hard disk device 30 can also be fixed (coupled) to the casing 12 by simply tightening one screw 24. . That is, when the screw 24 is inserted from above the HDD cover 20 and screwed into the screw hole 34 a of the mounting plate 34, the mounting plate 34 is lifted upward, and the HDD cover 20 and the cover mounting portion 12 c are connected to the mounting plate 34. It is sandwiched between the head of the screw 24 and pressed. Thereby, the HDD cover 20 is pressed and fixed from above to the cover mounting portion 12c which is a part of the housing 12, and the mounting plate 34 of the hard disk device 30 is also pressed from below to the cover mounting portion 12c. To be fixed.

  When tightening the screw 24, it is necessary to apply a certain pressing force in order to screw the tip of the screw 24 into the screw hole 34a of the mounting plate 34. At this time, as shown in FIG. 11, the mounting plate 34 is placed in contact with the edge of the slit 44, and the mounting plate 34 is lowered by the edge of the slit 44 (part of the housing 12). It is in a state supported from. Therefore, even if a pressing force is applied to the screw hole 34a from the top by the screw 24 at the beginning of the screw tightening, the screw hole 34 does not escape and the screw tightening can be surely performed.

  After the HDD cover 20 is fixed, the memory cover 22 is then fixed to the housing 22. Since the screw holes 34b of the mounting plate 34 are aligned with the through holes 28b of the cover placement portion 12c, the memory cover 22 is placed on the housing 12 and the memory cover 22 is placed in the same manner as the HDD cover 20. The memory cover 22 can be fixed by tightening the screw 26.
