Description

  The present invention relates to an electronic device and a holder that holds a hard disk drive device.

2. Description of the Related Art Conventionally, electronic devices such as a PC (Personal Computer) that records information on a hard disk drive (hereinafter sometimes abbreviated as “HDD”) and reads information from the HDD are known. Of these, for example, a PC generally has a structure in which an HDD is directly attached to the inside of the casing. Therefore, when installing or replacing the HDD, the HDD is directly installed in the casing after opening the casing combined with screws or the like. It was necessary to fix, and the installation and replacement work of the HDD was large and troublesome.
In order to solve such a problem, an electronic device (data storage device) that can insert and remove an HDD from an opening formed in a housing is known (for example, see Patent Document 1).

  In the data storage device described in Patent Document 1, there is an internal space for accommodating a hard disk drive unit (hereinafter sometimes abbreviated as “HDD unit”) including an HDD and a holder (case) for holding the HDD. Is formed. When an HDD unit is attached to such a data storage device, the HDD unit is inserted into the opening, and the connector provided in the opening is connected to the connector of the HDD unit. In this state, a screw is inserted into the hole of the flange extending from the holder in a direction orthogonal to the insertion direction to the opening of the HDD unit, and the screw is fastened to the chassis of the data storage device. Thereby, it is possible to save the trouble of opening the housing and taking out the holder, and the HDD unit can be easily attached to the data storage device.

JP-A-9-306152

Here, when the connectors are connected to each other at the front end side in the HDD insertion direction, the position of the HDD is designed based on the dimensional tolerances of the apparatus-side connector and the HDD connector, and the accumulation (cumulative tolerance) of the dimensional tolerances. It may vary from the center position.
Specifically, when each connector is manufactured with a minimum value within the tolerance, the end of the HDD unit on the opening side (the end on the side away from the connector) is the back side (connector side) of the storage space. ). In such a case, depending on the contact state between the flange portion and the chassis, the connectors may not be properly connected.
On the other hand, when each connector is manufactured with the maximum value within the tolerance, the end portion is located on the front side (opening side) of the storage space. In such a case, an unnecessary gap may be generated between the flange portion and the chassis, and there is a possibility that the HDD unit is not properly fixed with screws.

  On the other hand, in the data storage device described in Patent Document 1, the HDD is movable with respect to the case, and after fixing the case to the chassis, the HDD and the case are fixed with the connectors connected to each other. However, in such a configuration, it is necessary to sequentially fix the case to the chassis and the HDD to the case on the side orthogonal to the insertion direction of the HDD unit, and it is troublesome to attach the HDD to the data storage device. There is a problem that. For this reason, there has been a demand for a configuration in which the HDD can be easily and appropriately attached.

  The objective of this invention is providing the electronic device and holder which can attach a hard-disk drive apparatus to an electronic device main body simply and appropriately.

  In order to achieve the above-described object, an electronic device of the present invention includes an electronic device main body having an opening, a hard disk drive device, and a holder that holds the hard disk drive device and is accommodated in the opening. In the electronic device, the hard disk drive device has a connection terminal on the distal end side in the insertion direction of the holder into the opening, and the electronic device main body has the connection terminal on the distal end side in the insertion direction in the opening. A connecting portion connected along the insertion direction; and a fixing portion provided outside the opening and fixing the holder. The holder includes a bottom portion along the insertion direction, and the bottom portion. And a holder main body provided with an upright portion for fixing the hard disk drive device, and slidable along the bottom surface portion. And a slider fixed to the fixed portion, the bottom surface portion has a boss protruding in a direction facing the slider, and the slider is inserted into the boss, and the slider slides. A guide groove for guiding, the guide groove having an inclined portion inclined with respect to the insertion direction, and the boss being inclined when the slider is fixed at the fixing portion. It is located in a part.

Here, the inner diameter of the inclined portion indicates the shortest dimension between the oblique sides forming the inclined portion.
According to the present invention, when the holder for holding the hard disk drive device is inserted into the opening of the electronic device main body and the slider is slid along the bottom surface of the holder main body, the fixing provided outside the opening is performed. The slider is fixed to the part, and the holder is fixed to the electronic device main body. In this state, the boss provided on the bottom surface portion of the holder body is located at the inclined portion of the guide groove. For this reason, the position of the hard disk drive device and the holder main body in a state where the connection portion and the connection terminal are connected to each other by the accumulation of the dimensional tolerances of the connection portion in the opening and the connection terminal of the hard disk device (cumulative tolerance). However, when the slider is slid along the insertion direction of the holder, even if it is displaced from the design center position to the back side or the near side, the slider moves along the inclination of the inclined portion through which the boss is inserted. Move to. Thereby, the variation due to the accumulated tolerance can be absorbed, and the slider can be positioned at a position where it can be fixed to the fixing portion.

In this state, since the boss is located in the inclined portion, the slide in the direction opposite to the insertion direction of the holder main body with respect to the slider and the electronic device main body, and the direction orthogonal to the insertion direction, that is, each of the bosses Sliding in the direction is restricted by the inclined portion. In addition, sliding of the holder main body (boss) in the inclination direction of the inclined portion is restricted by the connection between the connection terminal and the connection portion.
Therefore, when replacing the hard disk drive device, the holder and the hard disk drive device can be appropriately and reliably fixed to the electronic device body regardless of the cumulative tolerance of the connection portion and the connection terminal of the hard disk device to be replaced. it can. Further, it is possible to restrict the holder and the hard disk drive device from being slid out of the electronic device main body when being fixed. Furthermore, the hard disk drive device can be fixed simply by inserting the holder to which the device is fixed into the opening and fixing the slider slid as described above at the fixing portion. It can be carried out.

  In addition, the holder of the present invention holds a hard disk drive device having a connection terminal connected to the connection portion provided in the opening of the electronic device main body at the front end side in the insertion direction of the opening, and is accommodated in the opening. A holder main body comprising a bottom surface portion along the insertion direction of the holder into the opening, a holder main body standing up from the bottom surface portion and fixing the hard disk device, and the bottom surface portion. A slider that is slidable along the holder body and that is fixed to the electronic device body, and the bottom surface portion has a boss that protrudes in a direction facing the slider, the slider being The boss is inserted and has a guide groove for guiding the slide of the slider, the guide groove has an inclined portion inclined with respect to the insertion direction, and the boss When Da is at a position that is fixed to the electronic device main body, characterized in that positioned in the inclined portion.

According to the present invention, the same effects as those of the above-described electronic device can be achieved.
That is, at the position where the slider is fixed to the electronic device main body, the boss is located at the inclined portion of the guide groove. For this reason, even when the position of the holder body when they are connected to each other is shifted from the design center position due to the accumulated tolerance of the connection terminal and the connection portion, the direction along the insertion direction of the holder and the orthogonal to the insertion direction By sliding the slider in the direction, the variation due to the accumulated tolerance can be absorbed, and the slider can be positioned at a position where the slider is fixed to the electronic device main body.
Further, at this time, the slide of the holder body in the direction opposite to the insertion direction of the holder and the direction orthogonal to the insertion direction, that is, the slide of the boss can be restricted by the inclined portion through which the boss is inserted. The sliding of the holder body in the inclination direction of the inclined portion can be restricted by the connection between the connection portion and the connection terminal.
Therefore, regardless of the accumulated tolerance of the connection terminal and the connection portion, the holder can be easily and appropriately fixed in the opening of the electronic device main body. When the holder is fixed, the holder main body and the hard disk drive device are It is possible to prevent the electronic device main body from sliding off.

In the present invention, it is preferable that the bottom portion has a plurality of the bosses, and the slider has a plurality of the guide grooves.
Here, when there is only one boss and one guide groove, the slider may turn around the boss, and not only the slider does not slide smoothly, but also after the slider is fixed. There is a possibility that the holder body rotates.
In contrast, in the present invention, the holder main body and the slider each have a plurality of bosses and guide grooves, so that the other rotation of the slider and the holder main body with respect to one can be restricted. Therefore, not only can the slider slide smoothly, but also the posture of the holder and the hard disk drive device in the opening can be stabilized.

In the present invention, the inner diameter of each of the inclined portions of the first guide groove and the second guide groove among the plurality of guide grooves is determined by the design of the boss inserted through the first guide groove and the second guide groove, respectively. It is preferable that the outer diameter of the boss and the minimum clearance on the processing accuracy of the boss and the guide groove are added.
Here, the inner diameter of the inclined portion indicates the shortest dimension between the oblique sides forming the inclined portion.
According to the present invention, rattling at the time of the other slide with respect to one of each inclined portion of the first guide groove and the second guide groove and each boss inserted through the guide groove can be minimized. . Therefore, the slide of the holder main body with respect to the slider and the electronic device main body when the slider is fixed can be more reliably regulated. Thereby, the holder can be more securely fixed to the electronic device main body, and the hard disk drive device can be reliably prevented from coming off from the electronic device main body.

  In the present invention, the plurality of guide grooves are connected to at least one end of the inclined portion on the insertion direction side and the direction opposite to the insertion direction, and along the insertion direction and the opposite direction. It is preferable to have an extending portion that extends in a direction away from the end portion.

  According to the present invention, since each guide groove has an extending portion, the slide range of the slider can be increased. Therefore, when the slider is fixed to the electronic device main body, when the slider protrudes from the holder main body, Or when the slider is located inside the holder body, the user can recognize that it is necessary to slide the slider. Further, when the boss is located in the extension part, the slider slides along the insertion direction of the holder, and when the boss is located in the inclined part, the slider is inserted in the holder insertion direction and the insertion direction. Since the slider slides in the direction orthogonal to the direction, the user can recognize that the slider is approaching the fixed position according to the slide direction of the slider.

In the present invention, the third guide groove and the fourth guide groove of the plurality of guide grooves are provided on straight lines along the insertion direction, respectively, and the extension of the third guide groove and the fourth guide groove is The inner diameter of the protruding portion is a dimension obtained by adding the outer diameter of the boss designed to pass through the guide groove having the extending portion and the minimum clearance for processing accuracy of the boss and the guide groove. preferable.
Here, the inner diameter of the extending portion indicates the shortest dimension of each side that forms the extending portion and faces each other, like the inner diameter of the inclined portion described above.
According to the present invention, when the boss is located in each extending portion of the third guide groove and the fourth guide groove arranged in series along the insertion direction of the holder, the insertion direction of the holder and the insertion direction with respect to the insertion direction The swinging of the slider when sliding in the opposite direction can be minimized. Therefore, rattling of the slider with respect to the holder body can be suppressed.

  In the present invention, the dimension of the inclined portion of any one of the third guide groove and the fourth guide groove is determined based on the design outer diameter of the boss that passes through the guide groove, the boss, and the guide. It is a dimension obtained by adding a minimum clearance on the processing accuracy of the groove, and the inner diameter of one of the other inclined parts is equal to the dimension of the one inclined part with the cumulative tolerance of the plurality of bosses and the plurality of guide grooves. The added dimensions are preferred.

  Here, when the inner diameters of the inclined portions of all the guide grooves are the dimensions obtained by adding the design outer diameter of the boss and the minimum clearance on the processing accuracy of the boss and the guide groove, each inclined portion in the slider The position of each boss and the position of each boss on the bottom surface portion cause interference between components due to the failure of the accumulated tolerance, and the slider cannot be attached to the bottom surface portion so that each boss is inserted. On the other hand, according to the present invention, the variation due to the accumulated tolerance is absorbed by the inclined portion of the other guide groove. Therefore, the slider can be securely attached to the holder body.

In this invention, it is preferable that the said inclination part inclines substantially 45 degrees with respect to the said insertion direction.
Here, when the inclination angle of the inclined portion approaches 0 °, sliding of the holder main body in the direction orthogonal to the insertion direction of the holder is sufficiently restricted by the slider fixed to the electronic device main body, but with respect to the insertion direction It becomes difficult to sufficiently regulate the sliding of the holder body in the opposite direction.
On the other hand, when the inclination angle of the inclined portion approaches 90 °, sliding of the holder body in the direction opposite to the insertion direction of the holder is sufficiently restricted, but orthogonal to the insertion direction when the slider is fixed to the electronic device body. The amount of movement of the slider in the direction increases. For this reason, a holder may enlarge.

  On the other hand, in the present invention, since the inclined portion is inclined by about 45 ° with respect to the insertion direction of the holder, the holder body slides in the direction opposite to and perpendicular to the insertion direction when the slider is fixed. As well as the amount of movement of the slider in the orthogonal direction can be reduced. Therefore, not only can the holder main body be fixed more reliably, but also the holder can be reduced in size, particularly the slider.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

These bosses 74A to 74C are inserted through guide grooves 9A to 9C of the slider 8, which will be described later. In the present embodiment, each boss 74 has a substantially cylindrical shape. However, the boss 74 is not limited thereto, and may have a substantially elliptical cylindrical shape, for example.

[Configuration of slider]
The slider 8 fixes the holder main body 7, and by extension, the holder 6 to the apparatus main body 3, and is attached to the holder main body 7 so as to be slidable along the bottom surface portion 71. The slider 8 has a plate-like slide portion 81 disposed along the bottom surface portion 71 and a right angle with respect to the slide portion 81 from the end of the slide portion 81 on the drawing direction A2 side to the side away from the HDD 5. And a flange portion 82 extending in the direction.
Among these, the flange portion 82 is formed with a long hole 821 that passes through the flange portion 82. The long hole 821 is formed such that the width direction A3 is the longitudinal direction. When the holder main body 7 is fixed to the apparatus main body 3, the long hole 821 is inserted with a screw S that is screwed into the screw hole 3141 of the storage portion 31.

The bosses 74A to 74C are inserted into the slide portion 81, respectively. Three guide grooves 9 for guiding the slide of the slider 8 (9A for the guide groove for inserting the boss 74A, 9B for the guide groove for inserting the boss 74B, 9B for the boss 74C 9C) is formed. Among these, the guide groove 9A corresponds to the first guide groove and the third guide groove of the present invention, and the guide grooves 9B and 9C correspond to the fourth guide groove and the second guide groove of the present invention, respectively.
The guide grooves 9A to 9C include inclined portions 9A1, 9B1, and 9C1, extended portions 9A2, 9B2, and 9C2 extending from the end portions on the insertion direction A1 side of the inclined portions 9A1 to 9C1, and the inclined portions 9A1 to 9A1. It has extension part 9A3, 9B3, 9C3 extended from the edge part of the drawing direction A2 side of 9C1.

  The inclined portions 9A1 to 9C1 are each formed by a pair of oblique sides 9A11, 9B11, and 9C11 that are inclined at an angle of 45 ° with respect to the insertion direction A1. The dimensions of the inclined portions 9A1 to 9C1 are set based on the outer diameters of the bosses 74A to 74C and the dimensional tolerances of the connectors 32 and 51. That is, the dimensions of the hypotenuses 9A11, 9B11, and 9C11 take into account the dimensional tolerances of the connectors 32 and 51, and provide a minimum clearance for processing within the range of the positions of the bosses 74A to 74C that vary within the cumulative range of the dimensional tolerances. It is set to be the added dimension. In addition, the said dimension of each inclination part 9A1-9C1 is respectively the same.

  Further, the inner diameter dimension of the inclined portions 9A1 and 9C1 (the shortest dimension between the pair of oblique sides 9A11 and 9C11) is substantially the same as the outer diameter of the bosses 74A and 74C, and the inner diameter dimension of the inclined portion 9B1 (between the pair of oblique sides 9B11). ) Is slightly larger than the boss 74B. That is, the inner diameters of the inclined portions 9A1 and 9C1 are the outer diameter at the time of designing the bosses 74A and 74C and the minimum clearance (for example, 0.05 mm) in the processing accuracy of the guide grooves 9A and 9C and the bosses 74A and 74C. It is set to the added dimension. Further, the inner diameter of the inclined portion 9B1 is obtained by adding the outer diameter at the time of designing the boss 74B, the minimum clearance in processing accuracy of the guide groove 9B and the boss 74B, and the accumulated tolerance of the guide grooves 9A to 9C and the bosses 74A to 74C. The dimensions are set.

  When such bosses 74A to 74C and the inclined portions 9A1 to 9C1 slide relative to each other, the two bosses 74A and 74C and the inclined portions 9A1 and 9C1 are used to connect the bosses 74A to 74C and the inclined portions 9A1 to 9C1. The rattling is suppressed. Even when the positions of the bosses 74A to 74C vary from the design center position due to accumulated tolerances or the like, the inclined portions 9B1 absorb the accumulated tolerances, and the bosses 74A to 74C pass through the inclined portions 9A1 to 9C1. Thus, the slider 8 can be disposed along the bottom surface portion 71.

In these inclined portions 9A1 to 9C1, the flange portion 82 of the slider 8 abuts against the extending portion 314 of the storage portion 31, and the slider 8 can be fixed to the apparatus body 3 (hereinafter referred to as "fixed position"). The bosses 74A to 74C are located respectively.
More specifically, when the connectors 32 and 51 are connected to each other and the slider 8 is in the fixed position, the bosses 74A to 74C are positioned at the centers of the insertion direction A1 and the width direction A3 in the inclined portions 9A1 to 9C1, respectively. As described above, the inclined portions 9A1 to 9C1 are designed. For this reason, when the positions of the HDD 5 and the holder body 7 are located on the back side (insertion direction A1 side) or the near side (extraction direction A2 side) of the storage unit 31 due to variations due to the accumulated tolerance of the connectors 32 and 51. However, when the slider 8 is in the fixed position, the bosses 74A to 74C are set so as to be positioned in the inclined portions 9A1 to 9C1, and the holder body 7 and the HDD 5 slide with respect to the fixed slider 8 (extraction direction A2). And slide in the width direction A3). Such restrictions on the slider 8 will be described in detail later.

5 and 6 are plan views showing the case where the slider 8 is positioned on the insertion direction A1 side and the drawing direction A2 side with respect to the holder body 7, respectively.
The extension portions 9A2 to 9C2 and 9A3 to 9C3 are for making the user recognize that the slider 8 is operated when the HDD unit 4 is stored in the storage portion 31, respectively. That is, as shown in FIG. 5, when the slider 8 is positioned on the insertion direction A1 side with respect to the holder main body 7, a long hole 821 (FIG. 3) of the slider 8 and a screw hole 3141 (see FIG. Since the position does not match 2), as shown in FIG. 6, the user recognizes the operation of pulling out the slider 8 and storing the HDD unit 4 in the storage unit 31 as shown in FIG. 6. Further, when the HDD unit 4 is completely stored in the storage portion 31, as shown in FIG. 4, the pulled-out slider 8 is pushed into the holder body 7, and the flange portion 82 is brought into contact with the extension portion 314. Then, the user is made to recognize the operation of fixing with the screw S.

Among these, the extension portions 9A2 to 9C2 are formed so as to extend in the insertion direction A1 from the end portions of the inclined portions 9A1 to 9C1 on the insertion direction A1 side, as shown in FIGS. Has been. Similarly, the extending portions 9A3 to 9C3 are formed so as to extend in the drawing direction A2 from the end portions on the drawing direction A2 side of the inclined portions 9A1 to 9C1.
The extending portions 9A2, 9A3, 9B2, and 9B3 are formed so that the inner diameters (dimensions in the width direction A3) are substantially the same as the outer diameters of the bosses 74A and 74B, and the extending portions 9C2 and 9C3 are respectively The inner diameter is formed to be slightly larger than the outer diameter of the boss 74C. That is, the inner diameters of the extending portions 9A2, 9A3, 9B2, and 9B3 are dimensions obtained by adding the design outer diameter of the bosses 74A and 74B and the minimum clearance in the processing accuracy of the bosses 74A and 74B and the guide grooves 9A and 9B. Is set to Further, the inner diameters of the extending portions 9C2 and 9C3 are the design outer diameter of the boss 74C, the minimum clearance in processing accuracy of the boss 74C and the guide groove 9C, and the cumulative tolerances of the guide grooves 9A to 9C and the bosses 74A to 74C. It is set to the dimension which added and.

  When the bosses 74A to 74C are positioned in the extension portions 9A2 to 9C2 or the extension portions 9A3 to 9C3, when the slider 8 is slid in the insertion direction A1 or the removal direction A2, the bosses 74A and 74B Oscillation (sliding in the width direction A3) of the slider 8 with respect to the holder body 7 is restricted by the extending portions 9A2, 9A3, 9B2, and 9B3 having an inner diameter substantially equal to the outer diameter. Even if the positions of the bosses 74A to 74C on the bottom surface 71 are different from the design center position, the extending portions 9A2 to 9C2 or the extending portions 9C2 and 9C3 have an inner diameter larger than the outer diameter of the boss 74C. Since the bosses 74A to 74C can be reliably positioned in the portions 9A3 to 9C3, not only the slider 8 can be provided along the bottom surface portion 71, but also the slider 8 can be smoothly slid.

  That is, since the inclined portions 9A1 to 9C1 and the extending portions 9A2 to 9C2 and 9A3 to 9C3 have the inner diameter as described above, one of the slider 8 and the holder body 7 slides relative to the other. In this case, the slide direction is defined by the two guide grooves, and the variation (size and position deviation) due to the accumulated tolerance can be absorbed by the other one guide groove.

Specifically, in the state where the bosses 74A to 74C are positioned in the extension portions 9A2 to 9C2 or the extension portions 9A3 to 9C3, the guide grooves 9A and 9B guide the one slide while suppressing the swinging, The guide groove 9C absorbs variations due to accumulated tolerances of the guide grooves 9A to 9C and the bosses 74A to 74C. In the state where the bosses 74A to 74C are positioned in the inclined portions 9A1 to 9C1, the guide grooves 9A and 9C guide the one slide while suppressing the swing, and the guide groove 9B is guided by these guide grooves 9A to 9C. In addition, the variation due to the accumulated tolerance of the bosses 74A to 74C is absorbed.
Therefore, among these guide grooves 9A to 9C, the guide groove 9A having a dimension obtained by adding the design outer diameter of the boss 74A and the minimum clearance in processing accuracy of the boss 74A and the guide groove 9A as the inner diameter is the slider 8. And a reference guide groove in the relative slide of the holder body 7.

[Boss position in the inclined part]
FIG. 7 is a schematic diagram showing the positional relationship between the boss 74A and the guide groove 9A when the slider 8 is at the fixed position. Specifically, in the center in FIG. 7, the solid line indicates the positional relationship between the boss 74 </ b> A and the guide groove 9 </ b> A when the holder body 7 is positioned at the position of the holder body 7 at the time of designing in the storage portion 31. . Further, on the left side and the right side in FIG. 7, the boss 74A and the guide groove 9A when the holder body 7 is positioned on the insertion direction A1 side and the extraction direction A2 side from the design center position due to variations due to the accumulated tolerances of the connectors 32 and 51. Are indicated by a two-dot chain line and a broken line, respectively.
As described above, when the flange portion 82 of the slider 8 and the extending portion 314 of the storage portion 31 are in contact with each other and the slider 8 is disposed at the fixed position, the bosses 74A to 74C are inclined portions 9A1 to 9C1. Located in.

  At this time, when the holder body 7 is located at the position of the holder body 7 in the storage portion 31 at the time of design, as shown in the center (solid line) of FIG. The center of 74A is located. Although not shown, in the inclined portions 9B1 and 9C1, the centers of the bosses 74B and 74C are located at the centers of the inclined portions 9B1 and 9C1. Thereby, when the slider 8 is fixed to the apparatus main body 3 with the screw S, the bosses 74A to 74C slide relative to the inclined portions 9A1 to 9C1 in the pulling direction A2 and the width direction A3, that is, the holder main body 7 with respect to the slider 8. The sliding of the HDD 5 in the directions A2 and A3 is restricted.

  On the other hand, due to the cumulative tolerance of the connector 32 of the apparatus main body 3 and the connector 51 of the HDD 5, the holder main body 7 is inserted in the insertion direction from the design center position of the holder main body 7 in the storage portion 31 within the range of the dimensional tolerance of the connectors 32 and 51. In the case where it is most shifted to the A1 side (the state on the left side in FIG. 7), the flange portion 82 of the slider 8 is brought into contact with the extending portion 314 of the storage portion 31, and the slider 8 is positioned at a fixed position. The protrusion of the slider 8 with respect to the holder body 7 is maximized from the center position. In other words, when the connectors 32 and 51 are formed to be the smallest within the range of the dimensional tolerance, the holder body 7 is positioned closest to the insertion direction A1 with respect to the slider 8 disposed at the fixed position. In this state, the straight line connecting the center C1 of the boss 74A and the center C of the inclined portion 9A1 is the hypotenuse, and the length of the side along the insertion direction A1 in the right triangle having two sides along the insertion direction A1 and the width direction A3 is Let L1.

  On the other hand, when the holder main body 7 is most displaced from the design center position in the drawing direction A2 side (the state on the right side in FIG. 7), when the slider 8 is positioned at the fixed position, the holder main body of the slider 8 from the design center position. The protrusion with respect to 7 becomes small. In other words, when the connectors 32 and 51 are formed to be the largest within the range of dimensional tolerances, the holder body 7 is positioned closest to the drawing direction A2 side with respect to the slider 8 arranged at the fixed position. In this state, the straight line connecting the center C2 of the boss 74A and the center C of the inclined portion 9A1 is the hypotenuse, and the length of the side along the insertion direction A1 in the right triangle having two sides along the insertion direction A1 and the width direction A3 is Let L2.

Even in these cases, as shown on the left side (two-dot chain line) and the right side (broken line) in FIG. 7, the boss 74A is located in the inclined portion 9A1, and the other bosses 74B and 74C are also located in the inclined portions 9B1 and 9C1. To do. For this reason, when the slider 8 is fixed to the apparatus main body 3, the slide of the holder main body 7 and the HDD 5 in the removal direction A2 and the width direction A3 with respect to the slider 8 is restricted as described above. The dimension L obtained by adding the length L1 and the length L2 corresponds to the dimensional tolerance of the connectors 32 and 51.
In this way, since the sliding of the HDD 5 and the holder body 7 with respect to the slider 8 is restricted, the apparatus body to which the slider 8 is fixed without depending on the variation due to the accumulated tolerance within the range of the dimensional tolerances of the connectors 32 and 51. 3 can prevent the HDD 5 and the holder main body 7 from coming off.

  In the state where the connectors 32 and 51 are connected to each other, the bosses 74A to 74C located in the inclined portions 9A1 to 9C1 slide in the inclination direction (direction along the oblique sides 9A11 to 9C11), that is, the inclination. The sliding of the holder main body 7 and the HDD 5 in the direction is regulated by the connection between the connectors 32 and 51.

The information processing apparatus 1 according to the present embodiment described above has the following effects.
(1) By sliding the slider 8 along the guide grooves 9 </ b> A to 9 </ b> C, the flange portion 82 of the slider 8 is accommodated in the housing portion regardless of variations due to the accumulated tolerance within the range of the dimensional tolerance of the connectors 32 and 51. The slider 8 can be placed at a fixed position by contacting the extension portion 314 of the slider 31. At this time, since the bosses 74A to 74C of the holder main body 7 are positioned in the inclined portions 9A1 to 9C1, when the slider 8 is fixed to the apparatus main body 3, the holder main body 7 and the HDD 5 are removed in the direction A2 and the width direction. A3 slide can be regulated. Further, the sliding of the holder main body 7 and the HDD 5 in the inclination direction of the inclined portions 9A1 to 9C1 can be restricted by the connection between the connectors 32 and 51. Therefore, the flange portion 82 of the slider 8 can be easily and appropriately fixed in the storage portion 31 regardless of variations due to the accumulated tolerances of the connectors 32 and 51. Further, when the slider 8 is fixed, the holder main body 7 and the HDD 5 can be prevented from sliding off the slider main body 7 and the storage portion 31 and falling off from the apparatus main body 3.

  (2) The bottom surface portion 71 and the slider 8 have a plurality of bosses 74A to 74C and a plurality of guide grooves 9A to 9C, respectively. According to this, the other rotation with respect to one of the holder main body 7 and the slider 8 can be controlled. Therefore, not only can the slider 8 be smoothly slid when the slider 8 is disposed at the fixed position, but the posture of the holder 6 and the HDD 5 in the storage portion 31 can be stabilized.

  (3) The inner diameters of the inclined portions 9A1 and 9C1 are dimensions obtained by adding the designed outer diameter of the bosses 74A and 74C and the aforementioned minimum clearance. According to this, rattling between the inclined portions 9A1 and 9C1 and the bosses 74A and 74C can be minimized. Therefore, the sliding of the holder main body 7 and the HDD 5 with respect to the slider 8 and the storage portion 31 when the slider 8 is fixed can be more reliably regulated.

  (4) Since each guide groove 9A-9C has the extension parts 9A2-9C2, 9A3-9C3, the slide range of the slider 8 can be enlarged. Accordingly, when the slider 8 protrudes from the holder main body 7 when the HDD unit 4 is stored in the storage portion 31, an operation of pushing the slider 8 into the holder main body 7 and the slider 8 is 7, when the long hole 821 and the screw hole 3141 do not match, the user can recognize the operation of pulling out the slider 8 from the holder body 7. Further, when the bosses 74A to 74C are positioned in the extending portions 9A2 to 9C2 and 9A3 to 9C3 in the operation of sliding and fixing the slider 8, the slider 8 slides along the insertion direction A1, When the boss is positioned in the inclined portions 9A1 to 9C1, the slider 8 slides along the inclined direction of the oblique sides 9A11 to 9C11. According to this, it is possible to make the user recognize that the slider 8 is approaching the fixed position due to the difference in the sliding direction of the slider 8. Therefore, the operability of the slider 8 can be improved.

  (5) The inner diameters of the extending portions 9A2, 9A3, 9B2, and 9B3 of the guide grooves 9A and 9B arranged in series along the insertion direction A1 are respectively the design outer diameters of the bosses 74A and 74B, The dimension is the sum of the bosses 74A and 74B and the guide grooves 9A and 9B with the minimum clearance for processing. According to this, as described above, when the bosses 74A to 74C are positioned in the extending portions 9A2 to 9C2 or the extending portions 9A3 to 9C3, the slider 8 swings when the slider 8 is slid. (Oscillation in the width direction A3) can be suppressed. Therefore, rattling of the slider 8 with respect to the holder body 7 can be suppressed.

  (6) The inner diameters of the inclined portions 9A1 and 9C1 are dimensions obtained by adding the designed outer diameter of the bosses 74A and 74C and the minimum clearance for processing the bosses 74A and 74C and the guide grooves 9A and 9C, respectively. On the other hand, the inner diameter of the inclined portion 9B1 is a dimension obtained by adding the accumulated tolerances of the bosses 74A to 74C and the guide grooves 9A to 9C to the dimension. Similarly, the inner diameters of the extending portions 9A2, 9A3, 9B2, and 9B3 are the design outer diameters of the bosses 74A and 74B, and the minimum clearance for processing the bosses 74A and 74B and the guide grooves 9A and 9B. Is the dimension obtained by adding the accumulated tolerances of the bosses 74A to 74C and the guide grooves 9A to 9C to the dimensions. According to this, even when the bosses 74A to 74C are provided at positions different from the design center position due to variations due to accumulated tolerances, the variations can be absorbed by the inclined portions 9B1 and the extending portions 9C2 and 9C3. . Therefore, the slider 8 can be securely attached to the holder body 7 along the bottom surface 71.

  (7) The oblique sides 9A11 to 9C11 of the inclined portions 9A1 to 9C1 are inclined by 45 ° with respect to the insertion direction A1, respectively, so that when the slider 8 is fixed, the holders in the drawing direction A2 and the width direction A3 The slide of the main body 7 can be regulated. Thereby, the sliding amount of the slider 8 in the width direction A3 can be reduced, and the length in the longitudinal direction (width direction A3) of the long hole 821 formed in the flange portion 82 can be reduced. Therefore, not only can the holder body 7 be fixed securely, but the slider 8 and thus the holder 6 can be downsized.
