Abstract

Improved workability in assembling a drive device, increased cooling efficiency of the drive device, and enhanced low noise characteristics in operation of the drive device are readily satisfied. To achieve this, projections (45) projecting in one direction from a base (42) of a HDD fixation member (41) are formed integrally with the base (42) by pressing. To attach a HDD (31) to the HDD fixation member (41), the HDD (31) is brought to be in contact with the projections (45) and connected to the projections (45). The HDD (31) can be attached from one direction, so that assembling workability is iimproved. Also, since the HDD (31) is connected to the projections (45), there is a gap between the HDD (31) and the base (42), and this increases cooling efficiency. In addition, the construction reduces possibility of presence of a very small gap between the HDD (31) and the base (42), which suppresses vibrational noise.

That is, of the four sides of the rectangle, the two opposing sides are formed in a direction that is substantially parallel to the side 43 of the base portion 42 located in the vicinity of the protruding portion 45. Further, of the two rectangular sides formed substantially parallel to the side 43 of the base part 42, the side located away from the side 43 of the base part 42 is formed with the same diameter as the length of this side. The semi-circle is connected so that the diameter direction of the semi-circle and the direction of the sides of the rectangle overlap. The semi-circle and the rectangle are combined together.

[0020] The four projecting portions 45 all project from the base portion 42 in this shape. The tip of the protruding portion 45 in the protruding direction is a flat portion 46 that is a plane parallel to the base portion 42. For this reason, the flat portions 46 formed on the four projecting portions 45 are all parallel. Further, the projecting portion 45 is provided with an inclined portion 47 that connects the flat portion 46 and the base portion 42.

[0021] The inclined portion 47 has a semicircular diameter that is a part of the protruding portion 45 in accordance with the direction force from the flat portion 46 to the base portion 42, and the shape of a portion of the protruding portion 45 is increased. In the rectangle, the length of the side formed substantially parallel to the side 43 of the base portion 42 located in the vicinity of the protruding portion 45 is increased. That is, the inclined portion 47 is inclined in the direction toward the outer side in the semicircular shape and the rectangular shape as it is directed from the flat portion 46 to the base portion 42.

FIG. 10 is a view of the HDD as viewed from the direction of the surface where it is attached to the HDD fixing member. The HDD 31 is an attachment surface to the HDD lower surface 32 force HDD fixing member 41 which is the lower surface of the HDD 31 in the normal use state of the information reproducing apparatus 1 in which the HDD 31 is installed. The HDD 31 is formed in a substantially rectangular parallelepiped shape. For this reason, the HDD lower surface 32 is formed in a substantially rectangular shape. The lower surface 32 of the HDD has a partial force on the four sides of the rectangle that is the shape of the lower surface 32 of the HDD. It protrudes in the direction opposite to the direction of the opposing surface, and this protruding portion is formed as an edge 33. In other words, the inner side of the edge portion 33 located at the outer peripheral portion of the HDD lower surface 32 has a shape recessed from the edge portion 33.

[0024] Further, on the lower surface 32 of the HDD, four mounting portions 34 having the same height as the edge portion 33 and also having a predetermined plane force are formed.

The shape is smaller than the flat portion 46 of the protruding portion 45. In other words, the flat portion 46 formed on the protrusion 45 of the HDD fixing member 41 is larger than the mounting portion 34 formed on the HDD 31, and the mounting portion 34 and the flat portion 46 are in contact with each other. In this case, any part of the attachment part 34 comes into contact with the flat part 46. Further, the four mounting portions 34 formed in this way are each formed with a screw hole 35. The relative positional relationship of the four through holes 48 formed in the four protrusions 45 of the HDD fixing member 41 is substantially the same as the relative positional relationship of the four screw holes 35 formed in the HDD 31. It has become a relationship.

FIG. 11 is a plan view showing a state where the HDD is attached to the HDD fixing member. FIG. 12 is a view taken along the line EE in FIG. FIG. 13 is a view taken along the line FF in FIG. FIG. 14 is a view taken along the line GG in FIG. FIG. 15 is a detailed view of part H in FIG. When installing the HDD 31 in the case unit 10 of the information reproducing apparatus 1, the HDD 31 is attached to the HDD fixing member 41. So Is attached to the HDD fixing member 41 so that the lower surface 32 of the HDD faces the HDD fixing member 41. Further, the HDD fixing member 41 has a surface of the base portion 42 on which the protruding portion 45 protrudes so as to face the HDD 31, and the protruding portion 45 contacts the HDD 31 so that the HDD 31 is attached to the HDD fixing member 41. That is, the base portion 42 has a surface facing the HDD 31, and the protruding portion 45 is formed on the surface facing the HDD 31 in the base portion 42. Further, the HDD 31 is attached to the HDD fixing member 41 by contacting the protruding portion 45 from the direction in which the protruding portion 45 of the HDD fixing member 41 protrudes.

Specifically, the flat surface portion 46 formed on the four projecting portions 45 of the HDD fixing member 41 and the four attachment portions formed on the HDD lower surface 32 are brought into contact with each other. In this state, the screw 60 as the connecting means is formed in the protruding portion 45 from the opposite direction to the direction in which the protruding portion 45 protrudes, that is, the opposite side of the protruding portion 45 to the side where the HDD 31 is in contact. The HDD 31 is connected to the protrusion 45 by passing through the screw 48 and screwing the screw 60 into the screw hole 35 formed in the mounting portion 34 of the HDD 31. The drive unit 30 is formed by connecting the HDD 31 and the projecting portion 45 in this way and attaching the HDD 31 to the HDD fixing member 41.

FIG. 16 is a schematic diagram showing a state in which the information reproducing apparatus shown in FIG. 2 also has the HDD removed. Further, the drive unit 30 is attached to the case portion 10 by connecting to the lower surface 14 of the lower case portion 12 through a screw (not shown) through a fixing hole 52 formed in the fixing member fixing portion 51 of the HDD fixing member 41. The direction is described with the HDD 31 removed. Of the four sides 43 of the base part 42, the direction in which the two sides 43 where the protrusions 45 are formed in the vicinity is the state in which the information reproducing apparatus 1 is assembled. It is mounted in a direction formed from the direction of the operation unit 15 to the side surface 13 to which the cooling fan 20 is mounted.

[0029] The information reproducing apparatus 1 according to this embodiment is configured as described above, and the operation thereof will be described below. Since the HDD 31 is attached to the HDD fixing member 41 by connecting the HDD 31 in contact with the protruding portion 45 from the direction in which the protruding portion 45 of the HDD fixing member 41 protrudes, the drive unit 30 is connected to the HDD fixing member 41. A gap is formed between the lower surface 32 and the base portion 42 of the HDD fixing member 41. This gap is in the base 42 It is formed along the base portion 42 between the two opposite sides 43 of the four sides 43 of the base portion 42. That is, since the base portion 42 is formed in a substantially rectangular shape, the opposing sides 43 are in two sets, so that the air gap communicates in two directions along the base portion 42. The drive unit 30 is installed in the case portion 10 in such a state that a gap is formed between the HDD lower surface 32 and the base portion 42 of the HDD fixing member 41 as described above.

In addition, a cooling fan 20 is provided inside the case portion 10. The cooling fan 20 operates according to the temperature in the case unit 10 when the information reproducing apparatus 1 is operated. When the cooling fan 20 is operated, the air in the case unit 10 passes through the cooling fan 20. Exhausted outside. Thereby, the air in case part 10 flows.

[0031] Further, when the information reproducing apparatus 1 operates, the HDD 31 of the drive unit 30 also operates. This HDD 31 is provided so that information can be stored in a node disk provided therein and information stored in a hard disk can be read. For example, when image information, audio information, etc. are stored in the HDD 31, these information are converted into electric signals and stored in a hard disk provided inside the HDD 31. In addition, when reproducing image information or audio information stored in the hard disk, the information stored in the hard disk is read, and this information is used as an electrical signal to other devices (not shown) included in the information reproducing apparatus 1. Communicate and play back this information.

[0032] Thus, the HDD 31 stores information on the hard disk, stores the force information provided so that the stored information can be read, and reads the stored information. The hard disk rotates during the process. As a result, it is possible to store information at an arbitrary position on the hard disk, or to read information stored at a predetermined position. In these cases, that is, when the HDD 31 operates. In the meantime, the HDD 31 generates heat. For this reason, there is a gap between the HDD lower surface 32 and the base portion 42 of the HDD fixing member 41, and the air in the case portion 10 flows. Air flows between the base portion 42 of the HDD fixing member 41. For this reason, heat exchange is easily performed between the HDD 31 and the air in the case unit 10, and the heat generated by the HDD 31 due to the operation of the HDD 31 becomes empty in the case unit 10. The temperature of HDD31 will be lowered.

Next, a method for assembling the drive unit 30 provided in the information reproducing apparatus 1 will be described. In the process of assembling the drive unit 30 in the process of assembling the information reproducing apparatus 1, when attaching the HDD 31 to the HDD fixing member 41, first, the HDD 31 is oriented so that the HDD lower surface 32 faces upward. Next, the HDD fixing member 41 is brought into contact with the mounting portion 34 of the lower surface 32 of the HDD with the flat surface portion 46 of the protruding portion 45 of the HDD fixing member 41 facing downward. After that, in the base part 42 of the HDD fixing member 41, the screw 60 is passed through the through hole 48 of the projecting part 45 from the surface opposite to the surface where the projecting part 45 projects, and formed in the mounting part 34 of the HDD 31. The screw hole 35 is screwed. As a result, the HDD 31 is connected to the protrusion 45, and the HDD 31 is attached to the HDD fixing member 41.

[0034] The HDD fixing member 41 provided in the information reproducing apparatus 1 described above has four projecting portions 45 formed on the base portion 42 when projecting in one direction. Is formed. For this reason, it is not necessary to change the orientation of HDD 31 or HDD fixing member 41 while attaching HDD 31 to HDD fixing member 41. By tightening screw 60 from one direction, protrusion 45 of HDD fixing member 41 is Connected to the HDD 31, the HDD 31 is attached to the HDD fixing member 41. This improves workability during assembly.

In addition, since the projecting portion 45 projects from the base portion 42, when the HDD 31 is connected to the projecting portion 45, a gap is generated between the HDD 31 and the base portion 42. As a result, the area where the HDD 31 comes into contact with the surrounding air increases, so that the HDD 31 can easily exchange heat with the surrounding air, or the HDD 31 can radiate heat to the surrounding air. In particular, since many of the devices and parts installed in the HDD 31 are mounted on the surface of the HDD 31 opposite to the lower surface 32 of the HDD, that is, the lower surface of the HDD 31, the HDD 31 During operation, the temperature of the HDD bottom surface 32 tends to rise. On the other hand, since the gap is formed between the HDD lower surface 32 and the base portion 42 where the temperature is likely to rise, the heat during the operation of the HDD 31 is more easily dissipated. Therefore, the cooling efficiency of the HDD 31 is ensured. [0036] Also, the HDD 31 and the HDD fixing member 41 are connected by contact only with the mounting portion 34 of the HDD 31 and the protruding portion 45 of the HDD fixing member 41. For this reason, the part other than the mounting part 34 of the HDD 31, for example, the distance between the edge part 33 of the HDD lower surface 32 and the base part 42 becomes a minute distance, and this part comes into contact when the information reproducing apparatus 1 or the HDD 31 is operated. It is possible to suppress chatter noise caused by moving away. As a result, it is possible to improve the quietness when the HDD 31 operates. Further, the protruding portion 45 formed on the HDD fixing member 41 and serving as a basis for these operations is easily formed integrally with the base portion 42 by a press carriage. As a result, it is possible to easily satisfy the improvement in workability at the time of assembly, the securing of the cooling efficiency of the HDD 31, which is an example of the drive device, and the improvement in the quietness when the HDD 31 is operated.

In addition, a flat portion 46 is formed on the protrusion 45, and the four flat portions 46 formed on the four protrusions 45 are all parallel to each other. For this reason, it is not necessary to obtain flatness in a large area when obtaining the flatness of the part where the HDD 31 is mounted. That is, when the protrusion 45 is not formed on the base part 42, and the HDD 31 is directly attached to the base part 42, the force required to obtain the flatness of the entire base part 42 is parallel to the four protrusions 45. Since the four flat portions 46 are formed, only the flat portion 46 has to be flat. For this reason, it is possible to manufacture the HDD fixing member 41 that allows the HDD 31 to be attached by creating a gap between the HDD 31 and the HDD 31 more easily. As a result, it is possible to more easily satisfy the improvement in workability at the time of assembly, the securing of the cooling efficiency of the HD D31, and the improvement in quietness during the operation of the HDD 31.

[0038] Further, since the flat portion 46 is larger in size than the mounting portion 34 formed on the HDD lower surface 32, a contact area can be secured when the HDD 31 is connected to the protruding portion 45. . For this reason, when the attachment portion 34 is brought into contact with the flat portion 46 of the protruding portion 45, the attachment portion 34 can be brought into contact more easily. Further, since the contact area between the mounting portion 34 and the flat portion 46 is ensured, the HDD 31 can be more reliably connected to the protruding portion 45. As a result, the workability during assembly can be further improved, and the ease of assembly can be improved.

[0039] Further, the HDD fixing member 41 including the base portion 42 and the protruding portion 45 is made of a metal material. Formed in the body. For this reason, by connecting the HDD 31 to the protrusion 45 and attaching the HDD 31 to the HDD fixing member 41, unnecessary electricity generated in the HDD 31 can flow to the HDD fixing member 41. The potential difference between the HDD 31 and other components of the information reproducing apparatus 1 can be removed. For this reason, it is possible to reduce the number of parts that do not require separate parts for removing this potential difference when the information reproducing apparatus 1 is operated. As a result, workability can be further improved, and costs can be reduced.

[0040] In addition, the drive unit 30 is attached to the HDD fixing member 41 by contacting the HDD 31 with the protruding portion 45 of the HDD fixing member 41 projecting! A gap can be formed between the base portion 42 of the fixing member 41 and the HDD 31.
