     DESCRIPTION OF EMBODIMENTS 
       [0028]    When a support member that is pivotable with respect to a housing is rotated and held at a certain angle to restrain the rotation, it is desired to improve the workability of working. 
         [0029]      FIG. 1  illustrates an example of a computer.  FIG. 2  is an exploded perspective view of a computer. The computer may be an electronic apparatus. External devices such as input/output devices and storage units and a communication line are coupled to a computer body  12  as desired. 
         [0030]    The computer body  12  includes a housing  14 . The housing  14  includes a housing body  16  having a bottom wall  16 B, a front wall  16 F, a rear wall  16 R, and side walls  16 A and  16 C, and includes a cover  18  that covers the housing body  16 . 
         [0031]    In descriptions below, the “front side” and “rear side” are respectively the front side (indicted by the arrow FR) and the rear side (opposite to the side indicated by the arrow FR) with respect to the housing  14 . The “front-and-rear direction”, “upper direction”, and “width direction” are the front-and-rear direction, upper direction (indicated by the arrow UP), and width direction (indicated by the arrow W) with respect to the housing  14 . 
         [0032]    Although, in  FIGS. 1 to 12 , the computer body  12  is placed such that the width direction is aligned with a horizontal direction (placed sideways), the computer body  12  may be placed such that the width direction is aligned with the vertical direction (placed upright) according to the usage status. The width direction and front-and-rear direction of individual structures may be interchanged (the structures may be oriented in a direction rotated by 90 degrees) depending on the structure of the computer body  12 . 
         [0033]    A mounting member  20  is mounted on the housing body  16  so as to be pivotable between a falling position (see  FIGS. 8A ,  8 B, and  8 C) and an erected position (see  FIGS. 11A ,  11 B, and  11 C) with respect to the housing  14 . In  FIGS. 2 ,  8 A,  8 B, and  8 C, the arrow R1 indicates the direction in which the mounting member  20  is rotated from the falling position to the erected position. 
         [0034]    An attachment unit  22  is provided in the mounting member  20 . A mounted member  62  to be mounted in the computer body  12  is attached to the attachment unit  22 . The mounted member  62  may include, for example, an optical disk drive  62 A and a hard disk drive  62 B. The mounting member  20  has an attachment unit  22 A, in which the optical disk drive  62 A is attached, and an attachment unit  22 B, in which the hard disk drive  62 B is attached. The mounted member  62  attached to the mounting member  20  is not limited to the optical disk drive  62 A and hard disk drive  62 B. 
         [0035]    A fixing piece  26  is secured to the side wall  16 A on one side of the housing body  16  with a fastener or the like. The fixing piece  26 , which is made of a metal plate, is formed into a desired form by making a slit at certain position of a metal plate, bending the metal plate, and machining such as perforating the metal plate. In machining on the metal plate, pressing, cutting, punching, laser beam irradiation, and the like may be appropriately combined. The fixing piece  26  is positioned so that a body  26 A is oriented in the front-and-rear direction of the housing  14 . 
         [0036]      FIGS. 3 ,  4 , and  5  are exploded perspective views of a housing and mounting member of a computer. As illustrated in  FIGS. 3 and 4 , holding plates  28  and  30 , which are formed by bending the metal plate of the body  26 A in the width direction of the housing  14 , are respectively formed on the front side and rear side of the fixing piece  26 . Holding holes  32  and  34  are respectively formed at the top of the holding plates  28  and  30  to pass through the holding plates  28  and  30  in the thickness direction, for example, a direction aligned with the front-and-rear direction of the housing  14 . 
         [0037]    The holding hole  32  in the holding plate  28  on the front side is formed in a perfect circular shape and has a female screw in its inner circumference. 
         [0038]    The holding hole  34  in the holding plate  30  on the rear side is substantially L-shaped and has a horizontal part  34 A which is a long hole extending in the width direction, and a vertical part  34 B which is formed long on the side wall  16 A side to extend downward from the horizontal part  34 A. 
         [0039]      FIGS. 6 and 7  are perspective views of a mounting member of a computer. As illustrated in  FIGS. 6 and 7 , a side plate  24  is formed on the side wall  16 A side of the mounting member  20  to extend downward. In the front-and-rear direction, the length of the side plate  24  is substantially the same as the length of the mounting member  20 . The side plate  24  has an upper plate  38  extending in the front-and-rear direction at the top, and has a front plate  40  and a rear plate  42  respectively extending from the front end and the rear end in the width direction. 
         [0040]    A support shaft  44  is formed at an upper portion of the rear plate  42  and extends toward the rear side. As illustrated in  FIG. 4 , the support shaft  44  is inserted into the holding hole  34  from the front side. 
         [0041]    A shaft hole  46 , which passes through the front plate  40  in its thickness direction, is formed at an upper portion of the front plate  40 . The shaft hole  46  is substantially L-shaped and has a horizontal part  46 A which is a long hole extending in the width direction, with the mounting member  20  in the falling state, and a vertical part  46 B, which is formed long on the side wall  16 A side to extend downward from the horizontal part  46 A. 
         [0042]    With the shaft hole  46  and holding hole  32  aligned, a shaft screw  48  is inserted into the shaft hole  46  and is screwed in the female screw of the holding hole  32 , as illustrated in  FIG. 3 . In this state, the axial line X1 (see  FIG. 3 ) of the shaft screw  48  is aligned with the axial line X2 (see  FIG. 4 ) of the support shaft  44 . For example, the mounting member  20  is mounted by the support shaft  44  on the rear side and by the shaft screw  48  on the front side so as to be pivotable around a rotation center line C1 (see  FIG. 5 ) with respect to the housing  14 . The support shaft  44  and shaft screw  48  may be a pivot shaft of the mounting member  20 . 
         [0043]    The shaft screw  48  may be, for example, a shoulder screw; an amount by which the shaft screw  48  is screwed in the holding hole  32  may be restricted within a certain range. Accordingly, a clearance equal to or larger than the thickness of the front plate  40  is left between the holding plate  28  and the head of the shaft screw  48 , and undesirable resistance against the rotation of the mounting member  20  may not be caused. 
         [0044]    The housing  14  has a clamping part  50  that partially clamps the mounting member  20  positioned at the falling position to restrain undesirable rotation of the mounting member  20 . When the mounting member  20  is pulled up toward the erected position against the clamping force of the clamping part  50 , the mounting member  20  may be unclamped. With the clamping part  50  in an unclamped state, the mounting member  20  becomes pivotable toward the erected position. 
         [0045]      FIG. 8A  is an A-A line cross sectional view when a mounting member is at the falling position.  FIG. 8B  is a B-B line cross sectional view when the mounting member is at the falling position.  FIG. 8C  is a C-C line cross sectional view when the mounting member is at the falling position. A-A line, B-B line, and C-C line are indicated in  FIG. 5 . As illustrated in  FIG. 8A , when the mounting member  20  is at the falling position, the shaft hole  46  is positioned at the bottom of the vertical part  46 B with respect to the shaft screw  48  as illustrated in  FIG. 8A ; for example, the shaft hole  46  is positioned at a high position relative to the position of the shaft screw  48 . At the horizontal part  34 A, the support shaft  44  is positioned on the side wall  16 A side. When the mounting member  20  is supported by, for example, a curved support edge  52 B, a state may be maintained in which the shaft screw  48  is positioned at the bottom of the vertical part  46 B and the support shaft  44  is positioned in the horizontal part  34 A on the side wall  16 A side. 
         [0046]    As illustrated in  FIGS. 3 and 4 , the fixing piece  26  has one or a plurality of support pieces  52 . Three support pieces  52  are formed with a space between each two support pieces  52  in the front-and-rear direction. The support piece  52  may be an example of a support member. 
         [0047]    The top of each support piece  52  is a wide portion  52 A, which is wide toward the side wall  16 A. The upper end of the wide portion  52 A is the curved support edge  52 B, which is curved to have an upward convex. The curved support edge  52 B is curved so that when the mounting member  20  is rotated from the falling position toward the erected position, the curved support edge  52 B supports the upper plate  38  of the mounting member  20  from below to guide the rotation of the mounting member  20  until an intermediate position in the rotation is reached. 
         [0048]    Grooves  24 B are formed in the side plate  24  and upper plate  38  of the mounting member  20  at positions corresponding to the curved support edges  52 B in the front-and-rear direction.  FIG. 9A  is an A-A line cross sectional view when a mounting member is rotated.  FIG. 9B  is a B-B line cross sectional view when a mounting member is rotated.  FIG. 9C  is a C-C line cross sectional view when a mounting member is rotated. A-A line, B-B line, and C-C line are indicated in  FIG. 5 . When the mounting member  20  is rotated from the falling position toward the erected position, the grooves  24 B are displaced toward the outside in the width direction until a rotation angle reaches a certain angle (see  FIGS. 9A ,  9 B, and  9 C). Therefore, the mounting member  20  may be supported at the side plate  24  and upper plate  38  by the curved support edges  52 B, and the downward motion of the mounting member  20  may be restricted. A state is maintained in which the shaft hole  46  is positioned at the bottom of the vertical part  46 B with respect to the shaft screw  48  and the shaft screw  48  is positioned at the bottom of the vertical part  46 B. 
         [0049]    If the rotation angle to the erected position of the mounting member  20  exceeds the above certain angle, the grooves  24 B move toward the inside in the width direction and reach the top of the curved support edges  52 B. The curved support edges  52 B are placed in the grooves  24 B and no longer support the mounting member  20 . This position at which the mounting member  20  is not supported may be referred to as a support cancel position. 
         [0050]    As illustrated in  FIG. 9A , the shaft screw  48  is positioned at the top end of the horizontal part  46 A, which is inclined in this state, and there is a clearance G between the shaft hole  46  and the top of the shaft screw  48 . The support shaft  44  is positioned on a boundary between the horizontal part  34 A and the vertical part  34 B, and there is a clearance between the holding hole  34  and the bottom of the support shaft  44 .  FIG. 10A  is an A-A line cross sectional view when a mounting member is rotated.  FIG. 10B  is a B-B line cross sectional view when the mounting member is rotated.  FIG. 10C  is a C-C line cross sectional view when the mounting member is rotated. A-A line, B-B line, and C-C line are indicated in  FIG. 5 . As illustrated in, for example,  FIGS. 10B and 10C , the curved support edges  52 B do not support the mounting member  20  (the side plate  24  and upper plate  38 ). Accordingly, the mounting member  20  is able to be displaced downward. If the mounting member  20  is at, for example, the erected position, the mounting member  20  may be displaced in a direction crossing the rotation center line C1, for example, in a downward direction orthogonal to the rotation center line C1. 
         [0051]    The holding hole  32  and shaft hole  46  may be an example of an accommodating hole. When the mounting member  20  is at the erected position, the shaft screw  48  and holding hole  32 , and the support shaft  44  and shaft hole  46  may be displaced in a direction crossing the rotation center line C1, for example, in a direction orthogonal to the rotation center line C1, and may be an example of a displacing member. 
         [0052]    The fixing piece  26  has one or a plurality of guide pieces  56 . For example, four guide pieces  56  may be formed with a space between the guide pieces  56  in the front-and-rear direction. 
         [0053]    The guide piece  56  and support piece  52  are displaced in the front-and-rear direction. As illustrated in  FIGS. 8B and 8C , when the fixing piece  26  is viewed in the front-and-rear direction, a retaining part  58 , which is slightly wider than the thickness of the upper plate  38  in the width direction, is formed between a widthwise inner side  56 S of the guide piece  56  and a widthwise outer side  52 S of the support piece  52 . The positions and shapes of the guide piece  56  and support piece  52  are determined so that the retaining part  58 , which is slightly wider than the thickness of the upper plate  38 , is formed, for example, between the guide piece  56  and the support piece  52 . 
         [0054]      FIG. 11A  is an A-A line cross sectional view when a mounting member is at an erected position.  FIG. 11B  is a B-B line cross sectional view when a mounting member is at an erected position.  FIG. 11C  is a C-C line cross sectional view when a mounting member is at an erected position. A-A line, B-B line, and C-C line are indicated in  FIG. 5 . As illustrated in  FIGS. 11B and 11C , with the upper plate  38  inserted into the retaining part  58 , the motion of the upper plate  38  in the width direction is restricted, so the rotation of the mounting member  20  is also suppressed. With the mounting member  20  at the erected position, a direction, indicated by the arrow M1, in which the upper plate  38  extends and a direction in which the upper plate  38  is inserted into the retaining part  58  are aligned with the displacement direction (downward direction) of the mounting member  20 . The upper plate  38  may be an example of a retained member. The retaining part  58  and upper plate  38  may be an example of a rotation suppressing member. 
         [0055]    At the top end of the guide piece  56 , a guide edge  56 A, which is shaped to be lowered from the side wall  16 A side toward the inside in the width direction, is formed. 
         [0056]    The upper plate  38  of the mounting member  20  has a non-contact concave part  60  at a position corresponding to the guide piece  56  in the front-and-rear direction. The non-contact concave part  60  is formed at a position at which the non-contact concave part  60  does not contact with the guide piece  56  as illustrated in  FIG. 9C  until the rotation angle reaches a certain angle, when the mounting member  20  is further rotated from the support cancel position toward the erected position. 
         [0057]    When the rotation angle to the erected position of the mounting member  20  exceeds the above certain angle, the bottom edge  60 A of the non-contact concave part  60  contacts with the guide edge  56 A. When the mounting member  20  is further rotated toward the erected position, the bottom edge  60 A slides downward and inside in the width direction along the guide edge  56 A. Therefore, due to the rotation of the mounting member  20 , the upper plate  38  is displaced downward while rotating and is guided to the retained position as indicated by the arrow M1 in  FIG. 9C , and is guided to a retained position at which the upper plate  38  is retained by the retaining part  58 . The contact position at which the upper plate  38  contacts with the guide edge  56 A may be referred to as a guide start position. The guide piece  56  may be an example of a guide member. 
         [0058]    When the cover  18  has been attached to the housing  14  as illustrated in  FIG. 1 , the cover  18  is removed from the housing  14 . In a factory or the like where the computer body  12  is manufactured, operation of rotating the mounting member  20  may be performed in the housing  14  to which the cover  18  has not been attached. 
         [0059]    When the mounting member  20  is at the falling position as illustrated in  FIGS. 8A ,  8 B, and  8 C, the upper plate  38  is supported by the curved support edge  52 B (see  FIGS. 8B and 8C ). Therefore, a state is maintained in which the shaft hole  46  is positioned at the bottom of the vertical part  46 B with respect to the shaft screw  48  (see  FIG. 8A ) and the shaft screw  48  is positioned at the bottom of the vertical part  46 B. 
         [0060]    To rotate the mounting member  20  to the erected position, the mounting member  20  is pulled up toward the erected position against the clamping force of the clamping part  50  to cancel the clamping. 
         [0061]    When the mounting member  20  is rotated in the direction indicated by the arrow R1 toward the erected position, the curved support edge  52 B supports the upper plate  38  and side plate  24  of the mounting member  20  from below until the mounting member  20  reaches the support cancel position (see  FIGS. 9B and 9C ). Since the upper plate  38  of the mounting member  20  slides on the curved support edge  52 B, undesirable downward movement, for example, is suppressed during the rotation of the mounting member  20 , enabling smooth rotation. 
         [0062]    When the mounting member  20  is rotated toward the erected position and reaches the support cancel position, the curved support edge  52 B enters the groove  24 B and the support of the mounting member  20  by the curved support edge  52 B is canceled (see  FIGS. 10B and 10C ). The clearance G (see  FIG. 9A ) is formed between the shaft screw  48  and the shaft hole  46 . A clearance is also formed between the holding hole  32  and the bottom of the support shaft  44 . Since the curved support edge  52 B does not support the mounting member  20 , the mounting member  20  is movable downward. 
         [0063]    When the mounting member  20  is further rotated toward the erected position, since the non-contact concave part  60  is formed in the mounting member  20 , the mounting member  20  (the bottom edge  60 A of the non-contact concave part  60 ) does not interfere (contact) with the guide piece  56  until the mounting member  20  reaches the guide start position. For example, the rotation of the mounting member  20  may not be restricted by the guide piece  56  or undesirable resistance may not be generated in the rotation. 
         [0064]    With the mounting member  20  at the guide start position, the upper plate  38  (the bottom edge  60 A of the non-contact concave part  60 ) contacts with the guide piece  56 . When the mounting member  20  is further rotated from the guide start position toward the erected position, due to the rotation of the mounting member  20 , the upper plate  38  moves downward and inside in the width direction while rotating as indicated by the arrow M1 in  FIG. 9C . Therefore, due to the rotation of the mounting member  20 , the rotation center line C1 (see  FIG. 5 ) of the mounting member  20  moves downward and inside in the width direction, and the upper plate  38  is guided to the retained position at which it is retained by the retaining part  58 . 
         [0065]    The mounting member  20  reaches the erected position as illustrated in  FIGS. 11A ,  11 B, and  11 C. At that time, the upper plate  38  is retained in the retaining part  58  (see  FIGS. 11B and 11C ). Thus, the rotation of the mounting member  20  is suppressed. Even if, for example, the force with which the mounting member  20  is supported is removed, undesirable falling to the falling position of the mounting member  20  is suppressed. 
         [0066]    Due to the rotation of the mounting member  20 , the rotation center line C1 is displaced. Due to the displacement of the mounting member  20 , part (the upper plate  38 ) of the mounting member  20  may be retained at the erected position of the mounting member  20  and the rotation of the mounting member  20  may be suppressed. Special operation to suppress the rotation of the mounting member  20  may not be desired. Workability may be improved. 
         [0067]    A new member, for example, a member placed between the mounting member  20  and the housing  14  is not desired to suppress the rotation of the mounting member  20  at the erected position and the number of parts is reduced. 
         [0068]    Since the shaft hole  46  and holding hole  34  are substantially L-shaped, when the mounting member  20  moves downward, the upper plate  38  is retained in the retaining part  58 , and the rotation of the mounting member  20  is suppressed. Since part of the mounting member  20  is retained and its rotation is suppressed, the pull-up of the mounting member  20  or its movement in the width direction, for example, may not be desired. Workability may be improved. 
         [0069]    The holding hole  32  and shaft hole  46  are substantially L-shaped. When the mounting member  20  is rotated from the guide start position to the falling position, the bottom edge  60 A of the upper plate  38  is guided by the guide edge  56 A, and the upper plate  38  is displaced in a direction indicated by the arrow M1 (see  FIG. 9C ). Due to the displacement of the upper plate  38  in a direction in which it is drawn toward the inside in the width direction, undesirable interference with the housing  14  (the side wall  16 A, the fixing piece  26 , and the like) may be suppressed during the rotation of portions of the mounting member  20  other than the bottom edge  60 A. In a structure in which, for example, the housing  14  is made small and various members are placed therein at a high density, interference between the mounting member  20  and the various members may be suppressed during the rotation of the mounting member  20 , the mounting member  20  may be held at the erected position, and the falling of the mounting member  20  may be suppressed. 
         [0070]    In a simplified structure in which the holding hole  34  is formed in the housing  14  and the shaft hole  46  is formed in the mounting member  20 , the mounting member  20  may be capable of moving in a direction crossing (in the above example, orthogonal to) the rotation center line C1 with the mounting member  20  at the erected position. 
         [0071]    When the upper plate  38  is retained in the retaining part  58 , the direction in which the mounting member  20  is displaced and the direction in which the upper plate  38  extends from the mounting member  20  (the direction indicated by the arrow M1) may be the same as illustrated in  FIGS. 11B and 11C . Since the upper plate  38  is retained, for example, in the retaining part  58  so as to be inserted into the retaining part  58  along the direction in which the upper plate  38  extends, the width of the retaining part  58 , for example, may be reduced within a range in which the upper plate  38  is able to be retained, for example, to about the thickness of the upper plate  38 . 
         [0072]    When the mounting member  20  is at the erected position, the mounted member  62  may be attached to or removed from the attachment unit  22  of the mounting member  20 . Since the mounting member  20  is maintained at the erected position, attachment and removal may be easy. 
         [0073]    When the mounting member  20  is returned from the erected position to the falling position, the mounting member  20  at the erected position is displaced upward as illustrated in  FIG. 12 . Due to this displacement, the upper plate  38  is no longer retained in the retaining part  58 . The mounting member  20  is rotated from the falling position to the erected position. Since the mounting member  20 , for example, the upper plate  38  and side plate  24  are supported by the curved support edge  52 B of the support piece  52 , the mounting member  20  may be stably rotated. 
         [0074]    The rotation center line C1 of the mounting member  20  positioned at the erected position is displaced downward and inside of the falling position in the width direction, for example, in a direction crossing the rotation center line C1. When part of the mounting member  20  is held, the displacement direction of the mounting member  20  may not be a direction crossing the rotation center line C1. For example, at the erected position, the mounting member  20  may be displaced backward and a holding member that holds part of the mounting member  20  may be provided behind the mounting member  20 . In this structure, a space in which the holding member is placed is formed behind the mounting member  20  in the housing  14 . The space behind the mounting member  20  may be used to place various members and wires of the computer body  12 . When the mounting member  20  is displaced in a direction crossing (particularly, orthogonal to) the rotation center line C1, since the mounting member  20  is not displaced backward, the space behind the mounting member  20  may be used to place other members. 
         [0075]    The support piece  52  (support member) and guide piece  56  (guide member) may be part of one fixing piece  26 . Alternatively, the support member and guide member may be separately provided. If the support member and guide member are formed as part of one fixing piece  26 , the support member and guide member are integrated, so the number of parts may be reduced. If the fixing piece  26  is secured when it is secured to the housing  14 , the support member and guide member are also secured at the same time, so workability may be improved. 
         [0076]    Since the support piece  52  (support member) and guide piece  56  (guide member) are formed as part of the fixing piece  26  by bending a single metal plate, the support member and guide member may not be integrated in a later process. 
         [0077]    The rotation of the mounting member  20  may be suppressed by retaining part of the mounting member  20  (the upper plate  38 ) by the retaining part  58  (the guide piece  56  and support piece  52 ). For example, when the mounting member  20  is at the erected position, part of the mounting member  20  may be engaged with the housing  14  to suppress the rotation of the mounting member  20 . When the rotation of the mounting member  20  is suppressed by retaining part of the mounting member  20  (the upper plate  38 ), a member for engagement may not be used. The structure may be simplified. 
         [0078]    With the mounting member  20  at the erected position, the whole of the mounting member  20  in the thickness direction, rather than part (the upper plate  38 ) of the mounting member  20 , may be retained. In a structure in which part (the upper plate  38 ) of the mounting member  20  is retained, the retaining part  58  may be made small. 
         [0079]    An engaged part that an engaging part engages may not be provided on the mounting member  20 . The structure of the mounting member  20  may be simplified by forming a retained member (the upper plate  38 ) retained in the retaining part  58 . 
         [0080]    The mounted member  62  may be the optical disk drive  62 A or hard disk drive  62 B. Other various mounted members  62  attached and mounted in the housing  14  are also allowed. 
         [0081]    An electronic apparatus may be the computer body  12 ; may be, for example, a computer with an integrated display unit. An electronic apparatus may be a computer; for example, a processing unit, or a recording and reproducing unit that handles electronic information (including video, images, voice data, and the like).
