         [0060]    The positions of the attachment holes are determined so that the relative positional relationship between the plural first attachment holes  134  and the plural third attachment holes  140  when the first storage member  122  and the second storage member  124  are arranged to form the first width in the longitudinal arrangement of a booklet is substantially identical to the relative positional relationship between the plural second attachment holes  136  and the plural fourth attachment holes  142  when the first storage member  122  and the second storage member  124  are arranged to form the second width in the transversal arrangement of a booklet. 
         [0061]    Specifically, the positions of the attachment holes are determined so that the pitch of the attachment holes formed in the same member is the distance L and the pitch of the attachment holes between the members is a distance T different from the distance L. 
         [0062]    In the first storage member  122 , the same attachment holes  150  as the attachment holes  134  and  136  formed in the wall portion  122 C are formed in the wall portion  122 D facing the wall portion  122 C. Similarly, in the second storage member  124 , the same attachment holes  152  as the attachment holes  140  and  142  formed in the wall portion  124 C are formed in the wall portion  124 D facing the wall portion  124 C. Accordingly, the first storage member  122  and the second storage member  124  have substantially the same shape.  FIG. 11  shows an example of the sizes in the first storage member  122  and the second storage member  124  having the same shape. 
         [0063]    Attachment holes formed in the side plate  116  and used to attach the booklet storage  120  to the apparatus body  10 A will be described below. 
         [0064]    As shown in  FIGS. 1 and 3 , four attachment holes  160  as an example of the attachment portions corresponding to the first attachment holes  134  and the third attachment holes  140  when the first storage member  122  and the second storage member  124  are arranged to form the first width in the longitudinal arrangement of a booklet are formed in the side plate  116 . 
         [0065]    According to this configuration, fasteners  162  as an example of a fixing tool are inserted into the first attachment holes  134  and the attachment holes  160  to fix the first storage member  122  to the side plate  116 . Similarly, the fasteners  162  are inserted into the third attachment holes  140  and the attachment holes  160  to fix the second storage member  124  to the side plate  116 . 
         [0066]    As described above, the relative positional relationship between the plural first attachment holes  134  and the plural third attachment holes  140  in the longitudinal arrangement of a booklet is equal to the relative positional relationship between the plural second attachment holes  136  and the plural fourth attachment holes  142  in the transversal arrangement of a booklet. 
         [0067]    Accordingly, as shown in  FIG. 2 , when the first storage member  122  and the second storage member  124  are arranged to form the second width in the transversal arrangement of a booklet, the attachment holes  160 , the second attachment holes  136 , and the fourth attachment holes  142  correspond to each other. Accordingly, the fasteners  162  are inserted into the second attachment holes  136  and the attachment holes  160  to fix the first storage member  122  to the side plate  116 . Similarly, the fasteners  162  are inserted into the fourth attachment holes  142  and the attachment holes  160  to fix the second storage member  124  to the side plate  116 . That is, the attachment holes  160  formed in the side plate  116  are used in common in the longitudinal arrangement of a booklet and in the transversal arrangement of a booklet. 
         [0068]    As shown in  FIGS. 3 and 4 , even when a booklet S of an A4 size is longitudinally stored in the booklet storage  120  in the longitudinal arrangement of a booklet (see  FIG. 3 ) and even when the booklet S of an A4 size is transversely stored in the booklet storage  120  in the transversal arrangement of a booklet (see  FIG. 4 ), the positions of the attachment holes  160  (see  FIGS. 1 and 2 ) are determined so as for the booklet S not to cover the openings of the first air inlet and outlet port  112  and the second air inlet and outlet port  114 . 
         [0069]    As shown in  FIG. 5 , at the time of shipment of the image forming apparatus  10  (see  FIG. 9 ) from a plant, the first storage member  122  and the second storage member  124  may be tied to each other so as to combine the opening of the first storage member  122  and the opening of the second storage member  124 . The first storage member  122  and the second storage member  124  may be shipped and carried in the tied state. 
         [0070]    As shown in  FIGS. 1 and 3 , in the longitudinal arrangement of a booklet, the first storage member  122  is disposed on the left side of the drawing surface, the second storage member  124  is disposed on the right side of the drawing surface, and the opening edge  164  of the first receiver portion  122 A and the opening edge  166  of the third receiver portion  124 A are opposed to each other. Accordingly, the first storage member  122  and the second storage member  124  are arranged to form the first width in the longitudinal arrangement of a booklet. 
         [0071]    In this state, the fasteners  162  are inserted into the first attachment holes  134  and the attachment holes  160  to fix the first storage member  122  to the side plate  116 . Similarly, the fasteners  162  are inserted into the third attachment holes  140  and the attachment holes  160  to fix the second storage member  124  to the side plate  116 . In the state where a booklet S of an A4 size is longitudinally arranged in the booklet storage  120 , the booklet S does not cover the openings of the first air inlet and outlet port  112  and the second air inlet and outlet port  114 . 
         [0072]    On the other hand, in the transversal arrangement of a booklet, the first storage member  122  is disposed on the right side of the drawing surface and the second storage member  124  is disposed on the left side of the drawing surface, as shown in  FIGS. 2 and 4 . Compared with the longitudinal arrangement of a booklet, the attachment directions of the first storage member  122  and the second storage member  124  are changed and the opening edge  168  of the second receiver portion  122 B and the opening edge  170  of the fourth receiver portion  124 B are brought into contact with each other. 
         [0073]    In this state, the fasteners  162  are inserted into the second attachment holes  136  and the attachment holes  160  to fix the first storage member  122  to the side plate  116 . Similarly, the fasteners  162  are inserted into the fourth attachment holes  142  and the attachment holes  160  to fix the second storage member  124  to the side plate  116 . In the state where a booklet S of an A4 size is transversely arranged in the booklet storage  120 , the booklet S does not cover the openings of the first air inlet and outlet port  112  and the second air inlet and outlet port  114 . 
         [0074]    As described above, by dividing the booklet storage  120  into the first storage member  122  and the second storage member  124  and changing the attachment directions of the first storage member  122  and the second storage member  124 , the first width and the second width different from the first width are formed. Accordingly, when the first width and the second width are used depending on applications thereof by the use of the first storage member  122  and the second storage member  124 , it is possible to select the direction in which a booklet S is placed. 
         [0075]    The same attachment holes  150  as the attachment holes  134  and  136  formed in the wall portion  122 C are formed in the wall portion  122 D facing the wall portion  122 C in the first storage member  122 . Similarly, the same attachment holes  152  as the attachment holes  140  and  142  formed in the wall portion  124 C are formed in the wall portion  124 D facing the wall portion  124 C in the second storage member  124 . The cutout  130  having the same shape as the cutout  128  formed in the first storage member  122  is formed in the second storage member  124 . Accordingly, the first storage member  122  and the second storage member  124  have substantially the same shape. The first storage member  122  may be attached to the side plate  116  by using the wall portion  122 D instead of the wall portion  122 C, and the second storage member  124  may be attached to the side plate  116  by using the wall portion  124 D instead of the wall portion  124 C. That is, without changing the arrangement of the first storage member  122  and the second storage member  124 , the first width in the longitudinal arrangement of a booklet and the second width in the transversal arrangement of a booklet may be formed by the use of the first storage member  122  and the second storage member  124 . 
         [0076]    By forming the cutout  128  in the first storage member  122  and forming the cutout  130  in the second storage member  124 , at least a part of the CD case K stored in the booklet storage  120  is externally exposed from the cutout  128  or the cutout  130  in the longitudinal arrangement of a booklet and the transversal arrangement of a booklet. 
         [0077]    In this Exemplary embodiments of the invention, the relative positional relationship between the plural (two in this exemplary embodiment) first attachment holes  134  and the plural (two in this exemplary embodiment) third attachment holes  140  when forming the first width is substantially identical to the relative positional relationship between the plural (two in this exemplary embodiment) second attachment holes  136  and the plural (two in this exemplary embodiment) fourth attachment holes  142  when forming the second width. Accordingly, the attachment holes  160  formed in the side plate  116  may be used in common in the longitudinal arrangement of a booklet and in the transversal arrangement of a booklet. 
         [0078]    Regarding the pitches of the attachment holes having the same relative positional relationship, the pitch of the attachment holes formed in the same member is the distance L and the pitch of the attachment holes between the members is the distance T different from the distance L. 
         [0079]    When a booklet S of an A4 size is arranged longitudinally (see  FIG. 3 ) and when a booklet S of an A4 size is arranged transversely (see  FIG. 4 ), the position of the attachment holes  160  are determined so as for the booklet S not to cover the opening of the first air inlet and outlet port  112  and the opening of the second air inlet and outlet port  114 . 
         [0080]    While the invention has been described in detail with reference to a specific exemplary embodiment, the invention is not limited to the exemplary embodiment, but may be modified in various forms without departing from the scope of the invention, which is obvious to those skilled in the art. For example, the booklet storage  120  is used in combination with the image forming apparatus  10  in the above-mentioned exemplary embodiment, but is not limited to the image forming apparatus  10  and may be used in combination with an electronic apparatus such as a facsimile. 
         [0081]    In the above-mentioned exemplary embodiment, it has been stated that a booklet S of an A4 size is arranged longitudinally and transversely. However, for example, when the size of the booklet S varies depending on the types (for example, an A4 size and an A3 size), different booklet widths (booklet sizes) may be coped with by the use of the booklet storage  120 . 
         [0082]    Although it has been stated in the above-mentioned exemplary embodiment that the first storage member  122  and the second storage member  124  have substantially the same shape, the first storage member and the second storage member are not limited to substantially the same shape or the substantially symmetric shape, but may have different shapes. 
         [0083]    It has been stated in the above-mentioned exemplary embodiment that the first receiver portion  122 A (the third receiver portion  124 A) and the second receiver portion  122 B (the fourth receiver portion  124 B) are connected to each other, but they may be separated from each other. 
         [0084]    As shown in  FIGS. 6 and 7 , in the above-mentioned exemplary embodiment, the booklet storage  120  is divided into the first storage member  122  and the second storage member  124 . Accordingly, by forming a particular attachment hole  174  in the side plate  116  and moving at least one of the first storage member  122  and the second storage member  124  in the horizontal direction, a booklet S of another size may be stored therein. 
         [0085]    In the above-mentioned exemplary embodiment, the booklet storage  120  is divided into the first storage member  122  and the second storage member  124 . Accordingly, a booklet S may be stored using any one thereof. For example, as shown in  FIGS. 10A and 10B , when an optional device  180  such as a sorter is attached to a side surface of the apparatus body  10 A, a stepped portion  182  may be formed between the optional device  180  and the apparatus body  10 A. The storage space for a booklet S may be formed using the first storage member  122  or the second storage member  124  and the stepped portion  182 . 
         [0086]    Although not particularly stated in the above-mentioned exemplary embodiment, the first storage member  122  or the second storage member  124  may be disposed inclined using only the first storage member  122  or the second storage member  124  and a booklet S may be stored therein. 
         [0087]    In the above-mentioned exemplary embodiment, the number of first attachment holes  134 , the number of second attachment holes  136 , the number of third attachment holes  140 , and the number of fourth attachment holes  142  are two, but the numbers are not limited to two but may be three or more. 
         [0088]    In the above-mentioned exemplary embodiment, the cutouts  128  and  130  for taking out the CD case K are formed in the first storage member  122  and the second storage member  124 , but may be formed in only any one. 
         [0089]    In the above-mentioned exemplary embodiment, the postures of the first storage member  122  and the second storage member  124  are determined in the longitudinal arrangement of a booklet by causing the opening edge  164  of the first receiver portion  122 A and the opening edge  166  of the third receiver portion  124 A to face each other. However, the shapes of the members may be determined so as to determine the postures of the first storage member  122  and the second storage member  124  by combining the opening edge  164  of the first receiver portion  122 A and the opening edge  166  of the third receiver portion  124 A with each other. 
         [0090]    In the above-mentioned exemplary embodiment, both the attachment direction of the first storage member  122  and the attachment direction of the second storage member  124  are changed in the longitudinal arrangement of a booklet and in the transversal arrangement of a booklet. However, the shapes of the members may be determined so as to distinguish the longitudinal arrangement of a booklet and the transversal arrangement of a booklet by changing only one attachment direction. 
         [0091]    In the above-mentioned exemplary embodiment, the first storage member  122  and the second storage member  124  are attached to the side plate  116  by the use of the fasteners  162 . However, the first storage member  122  and the second storage member  124  may be attached to the side plate  116  by the use of a double-sided tape or the like. In this case, the relative positional relationship between the first storage member  122  and the second storage member  124  is determined by bringing the opening edge  168  of the second receiver portion  122 B and the opening edge  170  of the fourth receiver portion  124 B into contact with each other.
