DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment in which a module-mounted device and an information processing device according to the present disclosure are applied will be described.

[0010] In the following, the XYZ coordinate system is defined and explained. The direction parallel to the X axis (X direction), the direction parallel to the Y axis (Y direction), and the direction parallel to the Z axis (Z direction) are mutually perpendicular. The XY plane is a horizontal plane, the +Z direction is the upward direction, and the -Z direction is the downward direction. Moreover, a planar view refers to a view on the XY plane. In the following, the length, width, thickness, etc. of each part may be shown exaggerated to make the configuration easier to understand.

[0011] <Embodiment> <Module mounting device 100> Fig. 1A is a diagram showing an example of the configuration of a module mounting device 100 of an embodiment. The module mounting device 100 has a housing 101, a panel 110, a panel 120, a panel 130, a joint member 140, and a guide rail 150. The panels 110, 120, and 130 are examples of a first panel, a second panel, and a third panel, respectively. The joint member 140 is an example of a joint member. Fig. 1A shows the inside of the housing 101 in a transparent manner.

[0012] Here, an example of the configuration of the module mounting device 100 will be described using FIG. 1B and FIG. 2A to FIG. 2G in addition to FIG. 1A. FIG. 1B is a diagram showing an example of the configuration of the panel 120, the panel 130, the joint member 140, and the guide rail 150. FIG. 2A is a diagram showing an example of the configuration of the panel 110. FIG. 2B is a diagram showing an example of the configuration of the front panel 120A. FIG. 2C is a diagram showing an example of the configuration of the rear panel 120B. FIG. 2D is a diagram showing an example of the configuration of the frame 120C. FIG. 2E and FIG. 2F are diagrams showing an example of the configuration of the panel 120. FIG. 2G is a diagram showing an example of the configuration of the panel 130. FIG. 2E shows only the gear 125C of the frame 120C, and omits the base 121C and the support 122C. In addition, in FIG. 2F and other figures, the thicknesses of the housing 101, the panel 110, the panel 120, and the panel 130 are omitted and shown in a plan view in order to make the configuration easier to understand.

[0013] The module mounting device 100 is a rack-type device mounting a plurality of electronic modules. The electronic module may be, for example, an optical module that photoelectrically converts an optical signal transmitted from an optical fiber into an electrical signal. The electronic module may also be an optical-optical relay adapter that relays an optical signal transmitted from an optical fiber. In this case, the information processing device of the embodiment including the electronic module and the module mounting device 100 is a device that performs signal processing and transmits a signal. The electronic module may also be, for example, a server. In this case, the information processing device including the electronic module and the module mounting device 100 is a rack server. The electronic module may also be a module other than those described above. The module mounting device 100 has a configuration that allows the plurality of electronic modules to be easily replaced.

[0014] Electronic modules such as optical modules or servers tend to generate more heat as the amount of data increases and the density of packaging increases, so it is necessary to ensure sufficient cooling performance. In addition to ensuring cooling performance, it is also desirable to reduce the power consumption of cooling devices such as cooling fans. From this perspective, the module mounting device 100 has a configuration capable of efficiently cooling multiple electronic modules. An example of the configuration of the module mounting device 100 will be described below.

[0015] In the module mounting device 100, the side where the panel 110 is located (-Y direction side) is the front side or front side, and the +Y direction side is the rear side or rear side. The front side where the panel 110 is located is the side where an electronic module is inserted into the module mounting device 100. However, the module mounting device 100 may also be capable of having an electronic module inserted from the rear side. Hereinafter, viewing the module mounting device 100 from the front side is referred to as a front view. Here, a front view is synonymous with a front view.

[0016] <Case 101> Housing 101 houses multiple electronic modules. Housing 101 has walls on the ±X direction sides and walls on the ±Z direction sides. A panel 110 is provided on the front side of housing 101, and the rear side is, for example, open. The end of housing 101 on the -Y direction side is front end 101A, and the end on the +Y direction side is rear end 101B.

[0017] It is sufficient that the housing 101 can house multiple electronic modules in a space surrounded by the ±X direction wall, the ±Z direction wall, and the panel 110. The ±X direction wall and the ±Z direction wall of the housing 101 may have a mesh structure with many holes, or a structure in which many holes are provided by a punching process. The ±X direction wall and the ±Z direction wall of the housing 101 may be walls without holes. The rear side of the housing 101 may be provided with walls similar to the ±X direction wall and the ±Z direction wall.

[0018] <Panel 110> 1A, panel 110 is a front panel provided on the front side of housing 101, and is fixed to a front end 101A of housing 101. Panel 110 is a rectangular plate-like member when viewed from the front. The longitudinal direction of panel 110 is the X direction. Panel 110 may be a part of housing 101, or may be configured to be provided separately from housing 101 and fixed to housing 101.

[0019] As shown in FIG. 2A, the panel 110 is a flat member having rectangular openings 111 and 112. The openings 111 and 112 are an example of a first opening. The openings 111 and 112 are provided in pairs in the vertical direction, and are arranged in the order of the openings 111, 112, 111, and 112 from top to bottom. A plurality of the openings 111 and 112 are provided in the X direction. As an example, 16 openings 111 and 112 are provided in the X direction. That is, the openings 111 and 112 are arranged in 4 rows and 16 columns when viewed from the front of the panel 110. The openings 111 and 112 are not limited to rectangular, and may be circular, elliptical, or other openings.

[0020] The opening sizes of the openings 111 and 112 are, for example, equal to each other and are opening sizes that allow the passage of an electronic module. The electronic module disposed inside the housing 101 through the opening 111 is fixed to the panel 110, whereas the electronic module disposed inside the housing 101 through the opening 112 is not fixed to the panel 110. The electronic module disposed inside the housing 101 through the opening 111 and the electronic module disposed inside the housing 101 through the opening 112 are in different positions in the Y direction when the panels 120 and 130 are moved backward. This will be described in detail later.

[0021] In addition, in cases where the size of the electronic module placed inside the housing 101 through opening 111 is different from the size of the electronic module placed inside the housing 101 through opening 112, the opening sizes of openings 111 and 112 may be different.

[0022] The portion of the panel 110 other than the openings 111 and 112 may be, for example, a mesh structure having many holes, or a structure in which many holes are provided by a punching process, etc. Furthermore, the portion of the panel 110 other than the openings 111 and 112 may be a wall portion having no holes.

[0023] <Panel 120> As shown mainly in Figures 1A, 1B, and 2B to 2F, the panel 120 has a front panel 120A, a rear panel 120B, and a frame 120C. The front panel 120A is an example of a second front opening. The rear panel 120B is an example of a second rear opening. The front panel 120A and the rear panel 120B are held by the frame 120C.

[0024] <Front panel 120A> The front panel 120A is provided inside the housing 101 as shown in FIG. 1A. The front panel 120A is a plate-like member having a rectangular shape when viewed from the front. The longitudinal direction of the front panel 120A is the X direction. The front panel 120A has rectangular openings 121A and 122A and a tooth portion 123A. The openings 121A and 122A are an example of a second opening and an example of a second front opening. The tooth portion 123A is an example of a first tooth portion. The openings 121A and 122A are not limited to a rectangular shape, and may be, for example, a circular or elliptical opening.

[0025] The openings 121A and 122A are provided two by two in the vertical direction, and are arranged from top to bottom in the order of the openings 121A, 122A, 121A, and 122A. A plurality of the openings 121A and 122A are provided in the X direction. As an example, 16 openings 111 and 112 are provided in the X direction.

[0026] The opening size of opening 121A is equal to the opening size of opening 111. Similarly, the opening size of opening 122A is equal to the opening size of opening 112. Here, the opening sizes of openings 111 and 112 are equal, as an example, and therefore the opening sizes of openings 121A and 122A are equal, as an example.

[0027] The arrangement of the 16 openings 121A and 122A is the same as the arrangement of the 16 openings 111 and 112. More specifically, the interval between adjacent openings 121A in the X direction and the interval between adjacent openings 122A in the X direction are equal to the interval between adjacent openings 111 in the X direction and the interval between adjacent openings 112 in the X direction. Moreover, the interval between adjacent openings 121A and 122A in the Y direction is equal to the interval between adjacent openings 111 and 112 in the Y direction.

[0028] When the front panel 120A and the panel 110 are at the same height, the positions of the openings 111 and 121A coincide with each other in a front view, and the positions of the openings 112 and 122A coincide with each other.

[0029] At both ends in the X direction of the front panel 120A, toothed portions 123A corresponding to the rack of a rack and pinion are provided. The toothed portions 123A have a plurality of teeth formed along the Z direction. The teeth of the toothed portions 123A engage with the gear 125C together with the toothed portions 123B of the rear panel 120B. The toothed portions 123A on the -X direction side have teeth facing the -X direction side, and the toothed portions 123A on the +X direction side have teeth facing the +X direction side. That is, the teeth of the two toothed portions 123A face outward in the X direction of the front panel 120A. The configuration of the toothed portions 123A will be described later together with the configurations of the toothed portions 123B of the rear panel 120B and the gear 125C of the frame 120C.

[0030] The portion of the front panel 120A excluding the openings 121A and 122A and the tooth portion 123A may be, for example, a mesh structure having many holes, or a structure in which many holes are provided by a punching process, etc. Also, the portion of the front panel 120A excluding the openings 121A and 122A and the tooth portion 123A may be a wall portion without holes.

[0031] <Rear panel 120B> As shown in FIG. 1A, the rear panel 120B is provided on the rear side of the front panel 120A inside the housing 101. The rear panel 120B is a plate-like member having a rectangular shape in a front view. The longitudinal direction of the rear panel 120B is the X direction. As an example, the size of the rear panel 120B in a front view is such that the length in the X direction is longer than that of the front panel 120A and the height in the Z direction is equal to that of the front panel 120A. The rear panel 120B has rectangular openings 121B and 122B and a tooth portion 123B. The openings 121B and 122B are an example of a second opening and an example of a second rear opening. The tooth portion 123B is an example of a second tooth portion. The openings 121B and 122B are not limited to a rectangular shape, and may be, for example, a circular or elliptical opening.

[0032] The openings 121B and 122B are provided two by two in the vertical direction, and are arranged from top to bottom in the order of the openings 121B, 122B, 121B, and 122B. A plurality of the openings 121B and 122B are provided in the X direction. As an example, 16 openings 121B and 122B are provided in the X direction.

[0033] The opening size of opening 121B is equal to the opening size of opening 111. Similarly, the opening size of opening 122B is equal to the opening size of opening 112. Here, the opening sizes of openings 111 and 112 are equal, as an example, and therefore the opening sizes of openings 121B and 122B are equal, as an example.

[0034] The arrangement of the 16 openings 121B and 122B is the same as the arrangement of the 16 openings 121A and 122A. More specifically, the interval between adjacent openings 121B in the X direction and the interval between adjacent openings 122B in the X direction are equal to the interval between adjacent openings 111 in the X direction and the interval between adjacent openings 112 in the X direction. Moreover, the interval between adjacent openings 121B and 122B in the Y direction is equal to the interval between adjacent openings 111 and 112 in the Y direction.

[0035] That is, the distance between adjacent openings 121B in the X direction and the distance between adjacent openings 122B in the X direction are equal to the distance between adjacent openings 121A in the X direction and the distance between adjacent openings 122A in the X direction. Also, the distance between adjacent openings 121B and 122B in the Y direction is equal to the distance between adjacent openings 121A and 122A in the Y direction.

[0036] When the rear panel 120B, front panel 120A, and panel 110 are at the same height, the positions of openings 111, 121A, and 121B are aligned in a front view, and the positions of openings 112, 122A, and 122B are aligned.

[0037] At both ends in the X direction of the rear panel 120B, toothed portions 123B corresponding to the rack of the rack and pinion are provided. The toothed portions 123B have a plurality of teeth formed along the Z direction. The teeth of the toothed portions 123B engage with the gear 125C together with the toothed portions 123A of the front panel 120A. The portions of the rear panel 120B at both ends in the X direction where the toothed portions 123B are provided protrude toward the -Y direction side from the portions of the rear panel 120B where the openings 121B and 122B are provided. The toothed portions 123B on the -X direction side have teeth facing toward the +X direction side and face the toothed portions 123A on the -X direction side of the front panel 120A. The toothed portions 123B on the +X direction side have teeth facing toward the -X direction side and face the toothed portions 123A on the +X direction side of the front panel 120A. That is, the teeth of the two toothed portions 123B face toward the center of the rear panel 120B in the X direction. The details of the configuration of the toothed portions 123B will be described later together with the configuration of the gear 125C of the frame 120C.

[0038] The portion of rear panel 120B excluding openings 121B and 122B and teeth 123B may be, for example, a mesh structure having many holes, or a structure in which many holes are provided by a punching process, etc. Also, the portion of rear panel 120B excluding openings 121B and 122B and teeth 123B may be a wall portion without holes.

[0039] <Frame 120C> 2D, the frame 120C has, for example, a base 121C, a support 122C, and a gear 125C. The frame 120C having the gear 125C is synonymous with the panel 120 having the gear 125C.

[0040] For example, base 121C is a member extending in the X direction and has a narrow width in the Z direction. For example, the length of base 121C in the X direction is equal to the length of rear panel 120B in the X direction. For example, base 121C is located on the -Y direction side of front panel 120A as shown in FIG. 2F.

[0041] The support portion 122C extends in the +Z direction from both ends of the base portion 121C in the X direction. As an example, the support portion 122C is located on the -Y direction side of the front panel 120A as shown in FIG. 2F, similar to the base portion 121C. The support portion 122C is located on the -Y direction side of the tooth portions 123A at both ends of the front panel 120A in the X direction. As an example, the position of the upper end of the support portion 122C is equal to the positions of the upper ends of the front panel 120A and the rear panel 120B. The base portion 121C and the support portion 122C are U-shaped members when viewed from the front.

[0042] The support portion 122C has a guide rail extending in the Z direction. Although the guide rail is not shown here, the front panel 120A and the rear panel 120B are engaged with the guide rail of the support portion 122C so as to be slidable in the Z direction. Furthermore, the support portion 122C can hold the front panel 120A and the rear panel 120B at any position in the up-down direction.

[0043] The base portion 121C and the support portion 122C may be integrally formed, or may be formed by joining together parts that are produced separately. The base portion 121C and the support portion 122C are, for example, made of metal.

[0044] A gear 125C equivalent to the pinion of a rack and pinion is rotatably provided at the center in the Z direction of the surface on the +Y direction side of the support portion 122C. One gear 125C is provided on the support portion 122C on the -X direction side and one gear 125C is provided on the support portion 122C on the +X direction side. The gear 125C is a circular gear and can rotate within the XZ plane. The gear 125C engages with the tooth portion 123A of the front panel 120A and the tooth portion 123B of the rear panel 120B.

[0045] <Positional Relationship and Operation of Tooth Portions 123A and 123B and Gear 125C> As shown in FIGS. 2E and 2F, the teeth portions 123A and 123B are disposed to sandwich the gear 125C in the X direction.

[0046] The teeth of the two toothed portions 123A of the front panel 120A face outward in the X direction of the front panel 120A, and the teeth of the two toothed portions 123B of the rear panel 120B face toward the center of the rear panel 120B in the X direction. The gear 125C engages with the toothed portions 123A and 123B located on both sides in the X direction.

[0047] Therefore, when tooth portion 123A moves upward, gear 125C rotates and tooth portion 123B moves downward. The same applies when the up-down direction is reversed. Also, when tooth portion 123B moves upward, gear 125C rotates and tooth portion 123A moves downward. The same applies when the up-down direction is reversed. Since the movement amounts of tooth portions 123A and 123B are equal, the movement amounts of front panel 120A and rear panel 120B are equal.

[0048] 1B, the -Y direction ends of the joint members 140 provided on both sides in the X direction are fixed to the lower ends of both ends in the X direction of the base 121C of the frame 120C. One joint member 140 is fixed to the lower end of each end in the X direction of the base 121C. The +Y direction ends of the joint members 140 are fixed to the lower ends of both ends in the X direction of the panel 130. For this reason, the distance in the Y direction between the panels 120 and 130 is constant.

[0049] Here, the panel 120 has the above-mentioned front panel 120A, rear panel 120B, and frame 120C, and the front panel 120A and the rear panel 120B are configured to be movable in opposite directions in the up-down direction relative to the frame 120C. However, the configuration of the panel 120 is not limited to this configuration, and may be any configuration as long as the front panel 120A and the rear panel 120B are configured to be movable in opposite directions in the up-down direction.

[0050] Also, here, a configuration has been described in which the movement amounts of the front panel 120A and the rear panel 120B are equal to each other. However, the panel 120 may be configured so that the movement amounts of the front panel 120A and the rear panel 120B are different. For example, the panel 120 may be configured so that the front panel 120A and the rear panel 120B are made slidable in the up-down direction relative to each other without using the gear 125C, and the front panel 120A and the rear panel 120B are slid manually.

[0051] <Panel 130> As shown in FIG. 1A, panel 130 is provided behind panel 120 inside housing 101. Panel 130 is a plate-like member that is rectangular in front view. The longitudinal direction of panel 130 is the X direction. As an example, the size of panel 130 in front view is approximately equal to the sizes of panels 110 and 120 in front view. Panel 130 has rectangular openings 131 and 132. Openings 131 and 132 are examples of a third opening. Note that openings 131 and 132 are not limited to a rectangular shape, and may be, for example, a circular or elliptical opening.

[0052] The openings 131 and 132 are provided two by two in the vertical direction, and are arranged from top to bottom in the order of the openings 131, 132, 131, and 132. A plurality of the openings 131 and 132 are provided in the X direction. As an example, 16 openings 131 and 132 are provided in the X direction.

[0053] The aperture size of the opening 131 is equal to the aperture size of the opening 111. Similarly, the aperture size of the opening 132 is equal to the aperture size of the opening 112. Here, the aperture sizes of the openings 111 and 112 are equal, as an example, and therefore the aperture sizes of the openings 131 and 132 are equal, as an example.

[0054] The arrangement of the 16 openings 131 and 132 is the same as the arrangement of the 16 openings 121A and 122A. More specifically, the interval between adjacent openings 131 in the X direction and the interval between adjacent openings 132 in the X direction are equal to the interval between adjacent openings 111 in the X direction and the interval between adjacent openings 112 in the X direction. Moreover, the interval between adjacent openings 131 and 132 in the Y direction is equal to the interval between adjacent openings 111 and 112 in the Y direction.

[0055] In other words, the distance between adjacent openings 131 in the X direction and the distance between adjacent openings 132 in the X direction are equal to the distance between adjacent openings 121A in the X direction, the distance between adjacent openings 122A in the X direction, the distance between adjacent openings 121B in the X direction, and the distance between adjacent openings 122B in the X direction.

[0056] Moreover, the interval between the openings 131 and 132 adjacent to each other in the Y direction is equal to the interval between the openings 121A and 122A adjacent to each other in the Y direction and the interval between the openings 121B and 122B adjacent to each other in the Y direction.

[0057] When the heights of panel 130, rear panel 120B, front panel 120A, and panel 110 are the same, the positions of openings 111, 121A, 121B, and 131 are the same when viewed from the front, and the positions of openings 112, 122A, 122B, and 132 are the same.

[0058] Additionally, ends on the +Y direction side of joint members 140 provided on both sides in the X direction are fixed to the lower ends of both ends in the X direction of the panel 130. The joint members 140 are also fixed to a base 121C of a frame 120C of the panel 120. For this reason, the distance in the Y direction between the panels 130 and 120 is constant.

[0059] The portion of the panel 130 other than the openings 131 and 132 may be, for example, a mesh structure having many holes, or a structure in which many holes are provided by a punching process, etc. Furthermore, the portion of the panel 130 other than the openings 131 and 132 may be a wall portion having no holes.

[0060] It should be noted that, behind the panel 130 inside the housing 101, as an example, electronic devices that perform signal processing, arithmetic processing, etc. on the digital signals output from the electronic modules 10 and 20 are disposed.

[0061] <Joint member 140> The joint member 140 (see FIG. 1B) is a rod-shaped member extending in the Y direction between an end portion on the -Y direction side fixed to the base 121C of the frame 120C of the panel 120, and an end portion on the +Y direction side fixed to the panel 130. As an example, one joint member 140 is provided on each side of the panels 120 and 130 in the X direction. The joint member 140 fixes the panels 120 and 130 together, and keeps the distance in the Y direction constant.

[0062] 1B shows the joint member 140 separated from the guide rail 150, the joint member 140 is slidable in the Y direction along the guide rail 150. Therefore, the panels 120 and 130 fixed by the joint member 140 are slidable along the guide rail 150 while maintaining a constant distance therebetween in the Y direction. The distance in the Y direction between the panels 120 and 130 fixed by the joint member 140 is shorter than the length in the Y direction from the opening 112 of the panel 110 to the interior of the housing 101 of the electronic module.

[0063] It should be noted that there needs to be at least one joint member 140, and there may be three or more. The joint member 140 needs only to be able to fix the panels 120 and 130 in the Y direction and keep the distance between the panels 120 and 130 in the Y direction constant, and may be provided between the upper and lower ends of the ±X direction sides of the panels 120 and 130, or on the upper or lower sides of the panels 120 and 130, etc. The joint member 140 may be located outside a space in which an electronic module, described later, may be present inside the housing 101.

[0064] <Guide rail 150> The guide rails 150 are arranged at the lower ends of both ends in the X direction inside the housing 101, and extend in the Y direction, for example. The guide rails 150 are rails having an L-shaped cross section in the XZ cross section, for example. The guide rails 150 guide the joint member 140 movably in the Y direction.

[0065] The end of the guide rail 150 on the -Y direction side is directly behind the panel 110 (directly behind the +Y side), and the position of the end on the +Y direction side is, for example, an appropriate position between the front end 101A and the rear end 101B of the housing 101. The guide rail 150 only needs to extend to a position on the +Y direction side that allows the panel 130 to be moved to a fourth position, which will be described later.

[0066] The guide rails 150 may have any shape in the XZ cross section as long as they can guide the joint members 140. The positions and number of the guide rails 150 may be adjusted to match the positions and number of the joint members 140.

[0067] <Mounting of Electronic Modules 10 and 20 onto Module Mounting Device 100> Fig. 3A is a diagram showing an example of the configuration of the information processing device 1 of the embodiment in a first state as seen from the front. Fig. 3B is a diagram showing an example of the configuration of a cross section taken along line AA in Fig. 3A. The cross section taken along line AA in Fig. 3A corresponds to the cross section taken along line AA in Fig. 1A. Figs. 3A and 3B show electronic modules 10 and 20. Fig. 3B also shows the thickness of each component.

[0068] The electronic module 10 is an example of a first electronic module, and the electronic module 20 is an example of a second electronic module. In Fig. 3B, cables 15B and 25B are connected to the rear sides of the electronic modules 10 and 20, respectively. The cables 15B and 25B are cables through which digital signals are output from the electronic modules 10 and 20.

[0069] The electronic modules 10 and 20 are a plurality of electronic modules mounted on the module mounting device 100. The electronic modules 10 and 20 are, for example, optical modules or servers, but here, as an example, a form in which the electronic modules 10 and 20 are optical modules will be described. The cross section along the line AA shown in FIG. 3B is a cross section including the side surfaces of the electronic modules 10 and 20 on the -X direction side. For this reason, FIG. 3B shows the side surfaces of the electronic modules 10 and 20 on the -X direction side, and cross sections of the housing 101, the panel 110, the front panel 120A, the rear panel 120B, and the panel 130. In FIG. 3B, the frame 120C of the panel 120, the joint member 140, and the guide rail 150 are omitted.

[0070] The electronic module 10 is attached to an opening 111 of a panel 110 via a rotating shaft 11 inside the housing 101. The front end of the electronic module 10 is attached to the rotating shaft 11. As an example, the front end of the electronic module 10 is a portion that is about 15% to 20% of the length of the electronic module 10 in the Y direction from the front end of the electronic module 10. Note that a hinge or the like may be used instead of the rotating shaft 11.

[0071] The electronic module 20 is attached to the opening 121B of the rear panel 120B via a rotating shaft 21 inside the housing 101. The front end of the electronic module 20 is attached to the rotating shaft 21. As an example, the front end of the electronic module 20 is a portion that is about 15% to 20% of the length of the electronic module 20 in the Y direction from the front end of the electronic module 20. Note that a hinge or the like may be used instead of the rotating shaft 21.

[0072] The electronic modules 10 and 20 are attached to the openings 111 and 121B, respectively, via the pivot shafts 11 and 21 in this manner not only in the first state, but also in the state in which the panels 120 and 130 are moved in the +Y direction.

[0073] The electronic modules 10 and 20 only need to be able to rotate a predetermined angle about the rotation shafts 11 and 21 as the rotation center when the front panel 120A is moved downward and the rear panel 120B is moved upward in a state in which the panel 120 is moved in the +Y direction to a second position described later. In addition, when the information processing device 1 is in use, the electronic modules 10 and 20 are rotated by a predetermined angle and held in a state inclined with respect to the horizontal plane. The predetermined angle is, for example, about 5 degrees to 30 degrees.

[0074] Here, for the sake of simplicity, the electronic modules 10 and 20 are described as components having a rectangular parallelepiped shape as an example. However, the electronic modules 10 and 20 may have various shapes in practice. Therefore, when the electronic modules 10 and 20 are inserted through the openings 111 and 112 of the panel 110, the openings 121A and 122A of the front panel 120A, the openings 121B and 122B of the rear panel 120B, and the openings 131 and 132 of the panel 130, gaps are generated between the electronic modules 10 and 20 and the openings.

[0075] Although the electronic modules 10 and 20 may be inserted into the housing 101 through the openings 111 and 112 of the panel 110, they may also be inserted into the housing 101 through the openings 131 and 132 of the panel .

[0076] <First state of information processing device 1> The first state of the information processing device 1 is an initial state of the information processing device 1. The first state of the information processing device 1 is a state in which the electronic modules 10 and 20 are attached to the rotating shafts 11 and 21 inside the housing 101, the front panel 120A and the rear panel 120B of the panel 120 are located at a first position, the panel 130 is located at a third position, and the panels 110, 120, and 130 satisfy the following conditions:

[0077] In the first state, the heights of the panels 110, 120, and 130 are aligned. That is, in a front view, the positions of the openings 111, 121A, 121B, and 131 are aligned, and the positions of the openings 112, 122A, 122B, and 132 are aligned.

[0078] Here, the first position is a position directly behind the panel 110 in the Y direction (directly behind the +Y side). When the front panel 120A and the rear panel 120B of the panel 120 are in the first position, the front panel 120A and the rear panel 120B are closest to the panel 110. The front panel 120A and the rear panel 120B are adjacent to each other in the Y direction, and strictly speaking, their positions in the Y direction are different, but the position where the front panel 120A and the rear panel 120B are both closest to the panel 110 is referred to as the first position. The front panel 120A and the rear panel 120B being located in the first position is synonymous with the panel 120 being located in the first position.

[0079] When the front panel 120A and the rear panel 120B are located at the first position, the surface on the -Y direction side of the support portion 122C of the frame 120C may be in contact with the surface on the +Y direction side of the panel 110. Also, when the front panel 120A and the rear panel 120B are located at the first position, there may be a very narrow gap of, for example, about several millimeters between the surface on the -Y direction side of the support portion 122C and the surface on the +Y direction side of the panel 110. When the front panel 120A and the rear panel 120B are located at the first position, the gap between the surface on the -Y direction side of the front panel 120A and the surface on the +Y direction side of the panel 110 is, for example, about several millimeters to several tens of millimeters.

[0080] The third position is located on the +Y direction side of the first position by the distance between the panels 120 and 130 joined by the joining member 140. The third position is the position where the panel 130 is closest to the panel 110.

[0081] 3A, when viewed from the front of the module mounting device 100, the electronic module 10 is visible in the opening 111, and the electronic module 20 is visible in the opening 112. Since the electronic module 20 is actually located in the opening 122B of the rear panel 120B, it is visible in the opening 122B through the openings 112 and 122A. The four small circles shown on the electronic modules 10 and 20 are connectors for connecting optical fibers.

[0082] 3B, in the first state, the electronic module 10 is inserted through the opening 111 of the panel 110, the opening 121A of the front panel 120A, and the opening 121B of the rear panel 120B. With the front end of the electronic module 10 attached to the opening 111 of the panel 110 via the rotating shaft 11, the portion of the electronic module 10 rearward of the front end is inserted and held through the openings 121A and 121B.

[0083] 3B, in the first state, the electronic module 20 is inserted through the opening 122B of the rear panel 120B and the opening 132 of the panel 130. The electronic module 20 is held with its rear end inserted through the opening 132 of the panel 130, with its front end attached to the opening 122B of the rear panel 120B via the rotating shaft 21. The rear end of the electronic module 20 is, for example, a portion that is about 15% to 20% of the length of the electronic module 20 in the Y direction from the rear end of the electronic module 20.

[0084] Next, the states of panel 110, front panel 120A, rear panel 120B, and panel 130 in the first state as viewed from the front will be described with reference to Figs. 3C to 3F. Fig. 3C is a diagram showing an example of the state of panel 110 as viewed from the front in the first state. Fig. 3D is a diagram showing an example of the state of front panel 120A as viewed from the front in the first state. Fig. 3E is a diagram showing an example of the state of rear panel 120B as viewed from the front in the first state. Fig. 3F is a diagram showing an example of the state of panel 130 as viewed from the front in the first state.

[0085] In the first state, as shown in FIG. 3C, electronic module 10 is located within opening 111 of panel 110, and electronic module 20 is not located within opening 112.

[0086] In the first state, as shown in FIG. 3D, electronic module 10 is located within opening 121A of front panel 120A, and electronic module 20 is not located within opening 122A.

[0087] In the first state, as shown in FIG. 3E, electronic module 10 is located within opening 121B of rear panel 120B, and electronic module 20 is located within opening 122B.

[0088] In the first state, as shown in FIG. 3F, electronic module 10 is not located in opening 131 of panel 130, and electronic module 20 is located in opening 132.

[0089] <Second State of Information Processing Device 1> Fig. 4A is a cross-sectional view showing an example of a state in which panels 120 and 130 are being moved in the +Y direction in information processing device 1. Fig. 4B is a cross-sectional view showing an example of a configuration of information processing device 1 in a second state according to an embodiment. In Figs. 4A and 4B, the thickness of each component is shown.

[0090] The second state is a state in which the panels 120 and 130 are moved to the second and fourth positions, respectively, in the information processing device 1. The cross sections shown in Figures 4A and 4B are cross sections at the same positions as the cross section shown in Figure 3B. Also, in Figure 4B, the rear end face of the electronic module 10 is indicated by reference numeral 10B, and the front end face of the electronic module 20 is indicated by reference numeral 20F. The rear end face 10B of the electronic module 10 and the front end face 20F of the electronic module 20 will be described later with reference to Figure 5B.

[0091] Here, the second position is a position where the front panel 120A and the rear panel 120B are moved in the +Y direction until the rear end of the electronic module 10 is removed from the opening 121B of the rear panel 120B. The front panel 120A and the rear panel 120B are adjacent to each other in the Y direction, and strictly speaking, their positions in the Y direction are different. However, the position where the rear end of the electronic module 10 is removed from the opening 121B of the rear panel 120B is referred to as the second position of the front panel 120A and the rear panel 120B. The front panel 120A and the rear panel 120B being located at the second position is synonymous with the panel 120 being located at the second position.

[0092] The fourth position is the position of the panel 130 when the front panel 120A and the rear panel 120B are located at the second position. The fourth position is located on the +Y side of the second position by the distance between the panels 120 and 130 joined by the joining member 140.

[0093] The state shown in FIG. 4A is a state (transient state) in the middle of moving the panels 120 and 130 while the information processing device 1 transitions from the first state shown in FIG. 3B to the second state shown in FIG. 4B. In this state, as shown in FIG. 4A, the electronic module 10 is inserted through the opening 111 of the panel 110, the opening 121A of the front panel 120A, and the opening 121B of the rear panel 120B. With the front end of the electronic module 10 attached to the opening 111 of the panel 110 via the rotating shaft 11, the portion between the front end and the rear end is inserted and held through the openings 121A and 121B. The rear end of the electronic module 10 is, for example, a portion from the rear end of the electronic module 10 that is about 15% to 20% of the length of the electronic module 10 in the Y direction.

[0094] 4A, the electronic module 20 has its front end attached to the opening 122B of the rear panel 120B via the pivot shaft 21, and its rear end inserted and held in the opening 132 of the panel 130. In this state, the electronic modules 10 and 20 overlap in the Y direction.

[0095] 4B, in the second state, the electronic module 10 is inserted through the opening 111 of the panel 110 and the opening 121A of the front panel 120A located at the second position, and the rear end of the electronic module 10 is removed from the opening 121B of the rear panel 120B located at the second position. With the front end of the electronic module 10 attached to the opening 111 of the panel 110 via the pivot shaft 11, the rear end of the electronic module 10 is inserted and held in the opening 121A.

[0096] 4B, in the second state, the electronic module 20 is inserted through the opening 122B of the rear panel 120B located at the second position and the opening 132 of the panel 130 located at the fourth position. The electronic module 20 has a front end attached to the opening 122B of the rear panel 120B via the pivot shaft 21, and a rear end inserted and held in the opening 132 of the panel 130.

[0097] In this manner, when the information processing device 1 is in the second state, the rear end of the electronic module 10 and the front end of the electronic module 20 do not overlap in the Y direction.

[0098] Next, the states of panel 110, front panel 120A, rear panel 120B, and panel 130 in the second state as viewed from the front will be described with reference to Figs. 4C to 4F. Fig. 4C is a diagram showing an example of the state of panel 110 as viewed from the front in the second state. Fig. 4D is a diagram showing an example of the state of front panel 120A as viewed from the front in the second state. Fig. 4E is a diagram showing an example of the state of rear panel 120B as viewed from the front in the second state. Fig. 4F is a diagram showing an example of the state of panel 130 as viewed from the front in the second state.

[0099] In the second state, as shown in FIG. 4C, electronic module 10 is located within opening 111 of panel 110, and electronic module 20 is not located within opening 112.

[0100] In the second state, as shown in FIG. 4D, electronic module 10 is located within opening 121A of front panel 120A, and electronic module 20 is not located within opening 122A.

[0101] 4E, in the second state, electronic module 10 is not located in opening 121B of rear panel 120B, and electronic module 20 is located in opening 122B. This is because in the second state, the rear end of electronic module 10 protrudes from opening 121B of rear panel 120B.

[0102] In the second state, as shown in FIG. 4F, electronic module 10 is not located in opening 131 of panel 130, and electronic module 20 is located in opening 132.

[0103] <Third state of information processing device 1> Fig. 5A is a cross-sectional view showing an example of the configuration of the information processing device 1 in a third state. In Fig. 5A, the thickness of each component is shown. The cross section shown in Fig. 5A is taken at the same position as the cross sections shown in Figs. 3B, 4A, and 4B.

[0104] The third state is a state in which the front panel 120A is moved downward and the rear panel 120B is moved upward from the second state of the information processing device 1. In the second state, the rear end of the electronic module 10 and the front end of the electronic module 20 do not overlap in the Y direction, so in the third state, the electronic modules 10 and 20 can be displaced without interference between the rear end of the electronic module 10 and the front end of the electronic module 20. In FIG. 5A, cables 15A and 25A are connected to the front sides of the electronic modules 10 and 20, respectively. The cables 15A and 25A are optical fiber cables that input optical signals to the electronic modules 10 and 20.

[0105] 5B is a front view transparently showing the positional relationship between the rear end face 10B of the electronic module 10 and the front end face 20F of the electronic module 20 in the second state of the information processing device 1. The rear end face 10B and the front end face 20F shown in FIG. 5B show the positional relationship between the rear end face 10B and the front end face 20F in FIG. 4B when viewed from the front.

[0106] FIG. 5C is a transparent view showing the positional relationship between the rear end face 10B of the electronic module 10 and the front end face 20F of the electronic module 20 in a front view when the information processing device 1 is in the third state.

[0107] In the second state, the front panel 120A and the rear panel 120B are not displaced in the vertical direction, so that the electronic modules 10 and 20 are parallel to the XY plane and have different height positions, so that the rear end face 10B and the front end face 20F are spaced apart in the Z direction, as shown in FIG. 5B.

[0108] In the third state shown in Fig. 5A, compared to the second state shown in Fig. 4B, the front panel 120A is displaced downward and the rear panel 120B is displaced upward, so that the rear end surface 10B and the front end surface 20F overlap in the Z direction as shown in Fig. 5C. That is, the rear end surface 10B and the front end surface 20F have an overlapping portion as shown in Fig. 5C.

[0109] 5D is a diagram illustrating an example of a configuration of the information processing device 1 according to the embodiment in a front view in the third state. In the third state, as illustrated in FIG. 5D, when viewed from the front of the module mounting device 100, the electronic module 10 is visible in the opening 111, but the electronic module 20 is not visible in the opening 112.

[0110] As shown in Fig. 5A, the electronic module 20 is located on the +Y direction side of the electronic module 10, and the front panel 120A is displaced downward and the rear panel 120B is displaced upward, so that the rear end face 10B and the front end face 20F overlap in the Z direction as shown in Fig. 5C. For this reason, in the third state, the electronic module 20 is almost invisible in the opening 112 when viewed from the front of the module mounting device 100.

[0111] The presence or absence of electronic modules 10 or 20 in each opening of panel 110, front panel 120A, rear panel 120B, and panel 130 in the third state is similar to the state shown in Figures 4C to 4F for the second state, so no explanation will be given.

[0112] Fig. 5E is a diagram showing an example of a space that exists around the electronic modules 10 and 20 in the housing 101 in the third state. In Fig. 5E, the thickness of each component is shown. As shown by the dashed oval in Fig. 5E, a space exists around the electronic modules 10 and 20.

[0113] Fig. 5F is a diagram showing an example of an air flow path obtained within housing 101 in the third state. Fig. 5F shows the thickness of each component. Here, as an example, a flow path will be described in which an electric fan is placed on the +Y side of panel 130 to suck air in. Note that the same applies if an electric fan is placed on the -Y side of panel 110 to exhaust air.

[0114] As shown in FIG. 5F, the electronic module 20 is located on the +Y direction side of the electronic module 10, and the front panel 120A is displaced downward and the rear panel 120B is displaced upward, so that a flow path is obtained that runs diagonally downward from the panel 110 to the panel 130, as shown by the flow path of the arrow (A). The flow path of the arrow (A) is a flow path that passes from the upper opening 112 of the panel 110 through the upper opening 122A of the front panel 120A and the lower opening 121B of the rear panel 120B to the lower opening 131 of the panel 130. The flow path of the arrow (A) passes between two electronic modules 10 in the vertical direction and between two electronic modules 20 in the vertical direction. The openings 122A and 121B have a smaller ventilation resistance than a wall portion having holes such as a mesh, and therefore have a high cooling effect.

[0115] Also, as shown by the arrow (B), the air passes through the wall of the panel 110 and the wall of the front panel 120A, passes through the upper opening 121B of the rear panel 120B and the upper opening 131 of the panel 130, and is obliquely downward from the panel 110 to the panel 130. The flow path of the arrow (B) passes over the upper electronic modules 10 and 20. When the air passes through the wall of the panel 110, it passes through holes in a mesh or the like of the wall of the panel 110, or passes through a gap between the upper opening 111 and the electronic module 10. When the air passes through the wall of the front panel 120A, it passes through holes in a mesh or the like of the wall of the front panel 120A, or passes through a gap between the upper opening 121A and the electronic module 10.

[0116] Also, as shown by the arrow (C), the air passes through the lower opening 112 of the panel 110 and the lower opening 122A of the front panel 120A, and then passes through the wall of the rear panel 120B and the wall of the panel 130, and a flow path is obtained that runs obliquely downward from the panel 110 to the panel 130. The flow path of the arrow (C) passes under the lower electronic modules 10 and 20. When the air passes through the wall of the rear panel 120B, it passes through holes in a mesh or the like of the wall of the rear panel 120B, or passes through a gap between the lower opening 122B and the electronic module 20, or the like. When the air passes through the wall of the panel 130, it passes through holes in a mesh or the like of the wall of the panel 130, or passes through a gap between the lower opening 132 and the electronic module 20, or the like.

[0117] In addition to the flow paths (A) to (C), if the walls on the ±X direction sides, the upper wall, and the lower wall of the housing 101 have holes such as meshes, various flow paths passing through the walls of the housing 101 are obtained in addition to the flow paths (A) to (C) obtained in the third state.

[0118] As described above, in the third state, electronic module 20 is positioned on the +Y direction side of electronic module 10, and front panel 120A is displaced downward and rear panel 120B is displaced upward, thereby obtaining a space indicated by the dashed ellipse inside housing 101. And, by obtaining a space indicated by the dashed ellipse inside housing 101, flow paths indicated by arrows (A) to (C) are obtained. Also, various flow paths are obtained in addition to the flow paths indicated by arrows (A) to (C).

[0119] 5F illustrates a flow path (arrows (A) to (C)) in which air flows from the front side where panel 110 is located to the rear side where panel 130 is located, but the flow path may be a flow path from the rear side where panel 130 is located to the front side where panel 110 is located. For example, such a flow path can be obtained when an electric fan is disposed on the -Y side of panel 110 for suction, or when an electric fan is disposed on the +Y side of panel 130 for exhaust.

[0120] The electronic modules 10 and 20 tend to generate more heat as the amount of data increases and the density of the packaging increases, so it is necessary to ensure sufficient cooling performance. At the same time as ensuring cooling performance, it is also desirable to reduce power consumption.

[0121] In the module mounting device 100 of the embodiment, the flow paths of the arrows (A) to (C) and various other flow paths are obtained by realizing the third state. Therefore, the module mounting device 100 can efficiently cool the multiple electronic modules 10 and 20.

[0122] In the above, a configuration has been described in which the rear end of the electronic module 10 is displaced downward and the front end of the electronic module 20 is displaced upward, but the rear end of the electronic module 10 may be displaced upward and the front end of the electronic module 20 may be displaced downward. Even in this case, a space is created around the electronic modules 10 and 20, and a flow path as shown by arrows (A) to (C) (see FIG. 5F) is obtained. In this case, a flow path is obtained that runs obliquely upward from the panel 110 toward the panel 130.

[0123] In the above, the configuration has been described in which the rear end of the electronic module 10 is displaced downward and the front end of the electronic module 20 is displaced upward. However, for example, the electronic modules 10 and 20 may be arranged adjacent to each other in the X direction, and the rear end of the electronic module 10 may be displaced to one of the +X and −X directions and the front end of the electronic module 20 may be displaced to the other direction.

[0124] Also, in the above, a configuration has been described in which the front end of the electronic module 20 is attached to the opening 122B of the rear panel 120B via the pivot shaft 21. However, the rear end of the electronic module 20 may be attached to the opening 132 of the panel 130 via the pivot shaft 21. Also, the front end of the electronic module 20 may be attached to the opening 122B of the rear panel 120B via the pivot shaft 21, and the rear end of the electronic module 20 may be attached to the opening 132 of the panel 130 via the pivot shaft 21.

[0125] <Effects> The module mounting device 100 comprises a housing 101 having a front end 101A and a rear end 101B in which the electronic module 10 and the electronic module 20 are housed, a panel 110 provided on the front end 101A side of the housing 101 and having openings 111 and 112 through which the electronic module 10 and the electronic module 20 can be inserted, the panel 110 being attached with the front end of the electronic module 10 inserted into the openings 111 and 112, and a panel 120 provided on the rear side of the panel 110 and having openings 121A, 122A, 121B, and 122B through which the electronic module 10 and the electronic module 20 can be inserted, the panel 120 being movable between a first position behind the panel 110 and a second position behind the first position, and in the first position, the electronic module 10 is movable between a first position behind the panel 110 and a second position behind the panel 110. The electronic module 20 includes a panel 120, the front end of which and the front end of the electronic module 20 are inserted through the openings 121A, 122A, 121B, and 122B, and the front end of the electronic module 20 is inserted through the openings 121B and 122B in the second position, and a panel 130 provided on the rear side of the panel 120 and movable between a third position rearward of the first position and a fourth position rearward of the third position, the front end of the electronic module 20 is attached to the panel 120, or the rear end of the electronic module 20 is attached to the panel 130, and in a state in which the panel 120 is located at the second position and the panel 130 is located at the fourth position, the panel 120 is displaceable to the first side in the vertical direction or the horizontal direction. Therefore, the rear end of the electronic module 10 and the front end of the electronic module 20 approach each other, creating a space around the electronic modules 10 and 20, and increasing the flow path in the direction from the front end 101A of the housing 101 toward the panel 130.

[0126] Therefore, it is possible to provide a module mounting device 100 with improved cooling efficiency.

[0127] Furthermore, in a state where the panel 120 is located at the second position and the panel 130 is located at the fourth position, the electronic modules 10 and 20 may have no overlapping section in the direction connecting the panels 110, 120, and 130. The electronic modules 10 and 20 can be displaced without interference between the rear end of the electronic module 10 and the front end of the electronic module 20, and more space can be secured around the electronic modules 10 and 20, increasing the flow path from the front end 101A of the housing 101 toward the panel 130. As a result, the cooling efficiency can be further improved.

[0128] Furthermore, the openings 111 and 112 may be two openings through which the electronic modules 10 and 20 can be inserted, respectively. The electronic modules 10 and 20 can be inserted through separate openings 111 and 112, respectively, and the electronic modules 10 and 20 can be displaced more stably.

[0129] Moreover, the panel 120 has a front panel 120A and a rear panel 120B disposed rearward of the front panel 120A, and the openings 121A, 122A, 121B, and 122B are openings 121A and 122A disposed in the front panel 120A, and openings 121B and 122B disposed in the rear panel 120B, and when the front panel 120A and the rear panel 120B are positioned in a first position, the front end of the electronic module 10 is inserted through the openings 121A and 122A, and the front end of the electronic module 20 is inserted through the openings 121B and 122B, and when the front panel 120A and the rear panel 120B are positioned in a second position, the rear end of the electronic module 10 is inserted through the openings 121A and 122A, and the front end of the electronic module 20 is inserted through the openings 121B and 122B. The front panel 120A and the rear panel 120B allow the rear end of the electronic module 10 and the front end of the electronic module 20 to be displaced more reliably, and more reliably create space around the electronic modules 10 and 20, thereby increasing the flow path from the front end 101A of the housing 101 toward the panel 130. This makes it possible to further improve the cooling efficiency.

[0130] Also, the front end of the electronic module 20 may be attached to the rear panel 120B. By moving the rear panel 120B, the electronic module 20 can be easily moved, and the front end of the electronic module 20 can be more reliably displaced by the rear panel 120B. This can further improve the cooling efficiency.

[0131] The panel 120 may further include a rotatable gear 125C, the front panel 120A may include a toothed portion 123A that can be engaged with the gear 125C and that is formed along a direction connecting the first side and the second side, and the rear panel 120B may include a toothed portion 123B that can be engaged with the gear 125C and that is formed along a direction connecting the first side and the second side, and when the front panel 120A is displaced to the second side, the rear panel 120B may be displaced to the first side with the rotation of the gear 125C. Since the front panel 120A and the rear panel 120B can be displaced in the opposite directions using the gear 125C, the electronic modules 10 and 20 can be displaced more reliably and easily, more space can be secured around the electronic modules 10 and 20, and the flow path in the direction from the front end 101A of the housing 101 toward the panel 130 is increased. As a result, the cooling efficiency can be further improved.

[0132] In addition, in a state in which the rear end of the electronic module 10 is displaced to the second side and the front end of the electronic module 20 is displaced to the first side, the rear end face 10B of the electronic module 10 and the front end face 20F of the electronic module 20 may have an overlapping portion in a front view. This allows more space to be secured around the electronic modules 10 and 20, and increases the number of oblique flow paths from the front end 101A of the housing 101 toward the panel 130, thereby further improving the cooling efficiency.

[0133] Furthermore, the openings 121A and 122A may be two openings through which the electronic modules 10 and 20 can be inserted, respectively. The electronic modules 10 and 20 can be inserted into separate openings 121A and 122A, respectively, and the electronic modules 10 and 20 can be displaced more stably.

[0134] Furthermore, the openings 121B and 122B may be two openings through which the electronic modules 10 and 20 can be inserted, respectively. The electronic modules 10 and 20 can be inserted through separate openings 121B and 122B, respectively, and the electronic modules 10 and 20 can be displaced more stably.

[0135] The housing 101 may further include a joint member 140 that joins the panels 120 and 130, and a guide rail 150 that is provided inside the housing 101 and guides the joint member 140, and the panels 120 and 130 may be movable in the direction connecting the panels 110 and 130 (Y direction) by the joint member 140 being guided along the guide rail 150. The panels 120 and 130 can be easily moved in the front-to-rear direction (Y direction) of the housing 101, and the cooling efficiency can be further improved.

[0136] The panel 130 may have openings 131 and 132 through which the electronic modules 10 and 20 can be inserted. The electronic modules 10 and 20 can be taken out of the housing 101 through the panel 130, and the cooling efficiency can be further improved by increasing the number of openings.

[0137] The openings 131 and 132 may be two openings through which the electronic module 10 and the electronic module 20 can be inserted, respectively. The electronic module 10 and the electronic module 20 can be inserted into separate openings 131 and 132, respectively, and the electronic module 20 can be displaced more stably.

[0138] The information processing device 1 includes an electronic module 10, an electronic module 20, and a module mounting device 100 mounting the electronic module 10 and the electronic module 20. The module mounting device 100 includes a housing 101 having a front end 101A and a rear end 101B in which the electronic module 10 and the electronic module 20 are accommodated, a panel 110 provided on the front end 101A side of the housing 101 and having openings 111 and 112 through which the electronic module 10 and the electronic module 20 can be inserted, and to which the front end of the electronic module 10 is attached with the openings 111 and 112 inserted, and a first position behind the panel 110 and a second position behind the first position. and a panel 130 provided on the rear side of the panel 120 and movable between a third position which is rearward of the first position and a fourth position which is rearward of the third position, the front end of the electronic module 20 being attached to the panel 120 or the rear end of the electronic module 20 being attached to the panel 130, and when the panel 120 is located at the second position and the panel 130 is located at the fourth position, the panel 120 is displaceable to the first side in the up-down direction or the left-right direction. As a result, the rear end of the electronic module 10 and the front end of the electronic module 20 approach each other, creating space around the electronic modules 10 and 20, and increasing the flow path from the front end 101A of the housing 101 toward the panel 130.

[0139] Therefore, it is possible to provide an information processing device 1 with improved cooling efficiency.

[0140] <First Modification> Fig. 5G is a diagram showing an example of a cross-sectional configuration of the information processing device 1A of the first modified example of the embodiment in a third state. In Fig. 5G, the thickness of each component is shown. The information processing device 1A has a configuration in which the module mounting device 100 of the information processing device 1 shown in Fig. 5A is replaced with a module mounting device 100A.

[0141] The module mounting device 100A has a configuration in which the positions of openings 111 and 112 of the panel 110, the positions of openings 121A and 122A of the front panel 120A, the positions of openings 121B and 122B of the rear panel 120B, and the positions of openings 131 and 132 of the panel 130 are swapped in the vertical direction.

[0142] Accordingly, in the information processing device 1A, the positions of the electronic modules 10 and 20 in the up-down direction are swapped.

[0143] In the information processing device 1A having such a configuration, as in the information processing device 1 shown in FIG. 5A, a flow path similar to the flow path shown by arrows (A) to (C) in FIG. 5F can be obtained, and a module-mounted device 100A and an information processing device 1A with improved cooling efficiency can be provided.

[0144] <Second Modification> 6A is a diagram showing an example of a configuration of an information processing device 1B of a second modified example of the embodiment in a first state as seen from the front. The information processing device 1B has a configuration in which the module mounting device 100 of the information processing device 1 of the embodiment is replaced with a module mounting device 100B.

[0145] The module mounting device 100B has a configuration in which the positions of the openings 111 and 112 of the panel 110, the positions of the openings 121A and 122A of the front panel 120A, the positions of the openings 121B and 122B of the rear panel 120B, and the positions of the openings 131 and 132 of the panel 130 are staggered in a front view. In other words, the arrangement of the openings 111 and 112 of the panel 110, the arrangement of the openings 121A and 122A of the front panel 120A, the arrangement of the openings 121B and 122B of the rear panel 120B, and the arrangement of the openings 131 and 132 of the panel 130 are switched up and down every other row. Accordingly, the electronic modules 10 and 20 are arranged in a staggered manner in a front view in the first state as shown in FIG. 6A.

[0146] Fig. 6B is a diagram showing an example of the state of panel 110 when viewed from the front in the first state. Fig. 6C is a diagram showing an example of the state of front panel 120A when viewed from the front in the first state. Fig. 6D is a diagram showing an example of the state of rear panel 120B when viewed from the front in the first state. Fig. 6E is a diagram showing an example of the state of panel 130 when viewed from the front in the first state.

[0147] 6B, in the first state, the electronic module 10 is located in the opening 111 of the panel 110, and the electronic module 20 is not located in the opening 112. Since the openings 111 and 112 are arranged in a staggered manner in front view, the electronic modules 10 are also arranged in a staggered manner in front view.

[0148] 6C, in the first state, the electronic module 10 is located in the opening 121A of the front panel 120A, and the electronic module 20 is not located in the opening 122A. Since the openings 121A and 122A are arranged in a staggered manner in front view, the electronic modules 10 are also arranged in a staggered manner in front view.

[0149] 6D, in the first state, electronic module 10 is located in opening 121B of rear panel 120B, and electronic module 20 is located in opening 122B. Since openings 121B and 122B are arranged in a staggered manner in front view, electronic modules 10 and 20 are also arranged in a staggered manner in front view.

[0150] 6E, in the first state, electronic module 10 is not located in opening 131 of panel 130, and electronic module 20 is located in opening 132. Since openings 131 and 132 are arranged in a staggered manner in front view, electronic modules 20 are also arranged in a staggered manner in front view.

[0151] In the second and third states of such information processing device 1B, the electronic modules 10 and 20 are arranged in a staggered manner in front view, which is different from the information processing device 1 of the embodiment, but a cooling effect can be obtained in the same manner.

[0152] As a result, the rear end of the electronic module 10 and the front end of the electronic module 20 approach each other, creating space around the electronic modules 10 and 20, and increasing the flow path from the front end 101A of the housing 101 toward the panel 130.

[0153] Therefore, it is possible to provide a module-mounted device 100B and an information processing device 1B with improved cooling efficiency.
