Housing and Electronics

[0001] The present disclosure relates to a housing and an electronic device.

[0002] Japanese Patent Application Laid-Open Publication No. 2020-128756 discloses a snap fit that engages a first member and a second member. A user can release the engagement between the first member and the second member by operating the snap fit.

[0003] Better housing and electronics are needed.

[0004] A first aspect of the present disclosure is a housing consisting of a plurality of housing members that can be combined with each other, comprising: a first engaging portion and a first engaging portion having a first engaging surface that engages with the first engaging portion; a second engaging portion and a second engaging portion having a second engaging surface that engages with the second engaging portion; one of the first engaging portion and the first engaging portion is provided on a first housing member of the plurality of housing members, the other of the first engaging portion and the first engaging portion is provided on a second housing member of the plurality of housing members, one of the second engaging portion and the second engaging portion is provided on the first housing member, and the other of the second engaging portion and the second engaging portion is provided on the second housing member; and a first gradient that is the gradient of the first engaging surface with respect to a first direction that is a direction perpendicular to a main surface of the housing member, and a second gradient that is the gradient of the second engaging surface with respect to the first direction are different from each other.

[0005] A second aspect of the present disclosure is an electronic device including the housing according to the first aspect of the present disclosure and an electronic component housed in the housing.

Fig. 2 is a perspective view of the electronic device shown in Fig. 1. Fig. 3 is an exploded perspective view of the electronic device shown in Fig. 2. Fig. 4 is a cross-sectional view of the electronic device shown in Fig. 1. Fig. 5 is a partial enlarged view of Fig. 4. Fig. 6 is a partial enlarged view of Fig. 4. Fig. 7A is a view showing a second engagement portion and a second locking portion. Fig. 7B is a view showing a second engagement portion and a second locking portion.

[0007] The prior art including JP 2020-128756 A has at least the following problem: In order to securely fasten the second member to the first member, it is preferable to provide a plurality of snap fits on the first member.

[0008] However, if the snap fit is installed in a position that is difficult for the user to reach, there is a problem that it is difficult for the user to operate the snap fit.

[0009] Based on the above preliminary explanation, one embodiment will be described below.

[0010] The first direction D1 in the following description is a direction perpendicular to a main surface 26s of a housing member 26 (described later). When an electronic device 10 (described later) is attached to the back 12b of the display device 12 (FIG. 1), the first direction D1 may coincide with the horizontal direction (the front-to-rear direction of the display device 12), but is not limited to this.

[0011] The second direction D2 in the following description is a direction perpendicular to the first direction D1. When the electronic device 10 described below is attached to the back 12b of the display device 12 (FIG. 1), the second direction D2 may coincide with the horizontal direction (the left-right direction of the display device 12), but is not limited to this.

[0012] The third direction D3 in the following description is a direction that is perpendicular to the first direction D1 and perpendicular to the second direction D2. When the electronic device 10 described below is attached to the back 12b of the display device 12 (FIG. 1), the third direction D3 may coincide with a vertical direction perpendicular to the horizontal plane (the up-down direction of the display device 12), but is not limited to this.

[0013] FIG. 1 is a rear perspective view showing an electronic device 10 according to an embodiment and a display device 12 to which the electronic device 10 is attached.

[0014] The electronic device 10 is a numerical control device that controls industrial machinery such as a machine tool, a robot, or an injection molding machine. Examples of machine tools include a machining center, a lathe, and a wire electric discharge machine. The electronic device 10 can be installed on a predetermined installation surface 14. The predetermined installation surface 14 is formed, for example, by the rear (back surface) 12b of the display device 12 shown in FIG. 1 . In this case, the electronic device 10 can be provided on the rear surface 12b together with, for example, peripheral components 16. Although not specifically illustrated, the front surface 12f of the display device 12 is provided with a display screen such as an LCD screen. The peripheral components 16 are components that are provided on the rear surface 12b of the display device 12 together with the electronic device 10. The peripheral components 16 are, for example, a connector unit 16A including a USB (Universal Serial Bus) connector, a memory card reader, and the like, but are not limited thereto.

[0015] Fig. 2 is a perspective view of the electronic device 10 shown in Fig. 1. Fig. 3 is an exploded perspective view of the electronic device 10 shown in Fig. 2.

[0016] 2, the electronic device 10 includes a housing 18 (see also FIG. 1). The housing 18 accommodates electronic components 20 included in the electronic device 10.

[0017] The electronic component 20 is mounted on, for example, a circuit board 22 ( FIG. 3 ). An electronic circuit configured with one or more electronic components 20, a conductor pattern (not shown), and the like is mounted on the circuit board 22. The electronic circuit includes, for example, a control circuit for controlling the above-described industrial machine. In this case, the electronic component 20 may be an integrated circuit chip 20A for controlling the industrial machine. The electronic circuit (control circuit) may control the display device 12 ( FIG. 1 ). The circuit board 22 may be provided with an external connector 24 for connecting the connector 100A of the connection cable 100 ( FIG. 1 ). The circuit board 22 may be provided with multiple external connectors 24. The connection cable 100 is, for example, a transmission cable, but is not limited thereto. For example, an external component (not shown) is connected to the circuit board 22 via the connection cable 100. The external component may be a portable electronic device or the like. The external connector 24 may electrically connect the external component to the above-described electronic circuit.

[0018] The housing 18 may accommodate a fan (not shown). The fan is an air-cooling device that cools a heat-generating element provided in the electronic device 10. The fan is, for example, an axial fan. The heat-generating element provided in the electronic device 10 is, for example, the electronic component 20 (circuit board 22) described above, but is not limited to this. When the housing 18 is provided with a fan, one or more vents (openings) (not shown) may be formed in the housing 18. In this case, at least one vent may be used, for example, as an air intake port for drawing cooling air into the internal space by the fan. At least one vent may be used as an exhaust port for expelling heat (hot air) from the internal space by the fan.

[0019] The housing 18 is made up of a plurality of housing members 26 that are combined with each other. For example, as shown in Figures 2 and 3, the plurality of housing members 26 include a first housing member 261 and a second housing member 262.

[0020] 3, each of the multiple housing members 26 has a main surface 26s that forms a part of the inner surface of the housing 18. For example, the first housing member 261 has a first main surface 26s1 that is the main surface 26s of the first housing member 261. The second housing member 262 has a second main surface 26s2 that is the main surface 26s of the second housing member 262.

[0021] The first main surface 26s1 and the second main surface 26s2 may face each other. For example, the first direction D1 is a direction perpendicular to the first main surface 26s1. In this case, the first direction D1 may be a direction perpendicular to the second main surface 26s2.

[0022] Furthermore, at least one housing member 26 has a standing wall portion (wall portion) 28. The standing wall portion 28 protrudes from a main surface 26s of the housing member 26 along a first direction D1. When multiple housing members 26 are combined, the standing wall portion 28 can function as an outer wall portion (side wall) of the housing 18. In this embodiment, a case will be described in which a first housing member 261 has the standing wall portion 28 ( FIG. 3 ).

[0023] The standing wall portion 28 may be configured by a plurality of partial wall portions 28p. The plurality of partial wall portions 28p may include, for example, a first partial wall portion 28p1, a second partial wall portion 28p2, a third partial wall portion 28p3, and a fourth partial wall portion 28p4, which will be described below.

[0024] The first partial wall portion 28p1 forms one side wall of the first housing member 261 in the second direction D2. When the electronic device 10 is provided on the back portion 12b of the display device 12 (FIG. 1), the first partial wall portion 28p1 serves as, for example, the right side wall of the housing 18.

[0025] The second partial wall portion 28p2 forms the other side wall in the second direction D2 of the first housing member 261. When the electronic device 10 is provided on the back portion 12b of the display device 12 (FIG. 1), the second partial wall portion 28p2 serves as, for example, the left side wall of the housing 18.

[0026] The third partial wall portion 28p3 forms one side wall of the first housing member 261 in the third direction D3. When the electronic device 10 is provided on the back portion 12b of the display device 12 (FIG. 1), the third partial wall portion 28p3 serves as, for example, the upper wall of the housing 18.

[0027] The fourth partial wall portion 28p4 forms the other side wall in the third direction D3 of the first housing member 261. When the electronic device 10 is provided on the back portion 12b of the display device 12 (FIG. 1), the fourth partial wall portion 28p4 serves as, for example, the bottom wall of the housing 18.

[0028] At least one of the plurality of partial wall portions 28p may be formed with a connector exposing portion 30 that exposes, for example, the above-described external connector 24. In this embodiment, a case where the connector exposing portion 30 is formed in the fourth partial wall portion 28p4 will be described. The connector exposing portion 30 may be formed, for example, by a notch 30A formed in the partial wall portion 28p, but is not limited to this. The connector exposing portion 30 may also be formed by an opening formed in the partial wall portion 28p. In this case, the partial wall portion 28p may be formed with a relatively large connector exposing portion 30 that exposes the plurality of external connectors 24 ( FIGS. 2 and 3 ), but is not limited to this. A plurality of relatively small connector exposing portions 30 corresponding to each of the plurality of external connectors 24 may be formed in the partial wall portion 28p.

[0029] The housing 18 includes a locking structure 32 for locking the first housing member 261 and the second housing member 262 to each other. The locking structure 32 includes an engaging portion 34 (one or more engaging portions 34) and a locking portion 36 (one or more locking portions 36) that engages with the engaging portion 34. The engaging portion 34 is provided on one of the first housing member 261 and the second housing member 262. On the other hand, the locking portion 36 is provided on the other of the first housing member 261 and the second housing member 262.

[0030] In this embodiment, a case will be described in which the second housing member 262 is provided with a plurality of engaging portions 34, and the first housing member 261 is provided with a plurality of locking portions 36 corresponding to the plurality of engaging portions 34. The plurality of locking portions 36 may be arranged on a plurality of partial wall portions 28p that form the wall portion of the housing 18. It is preferable that at least one locking portion 36 is arranged on each of the plurality of partial wall portions 28p. The plurality of engaging portions 34 are arranged corresponding to the plurality of locking portions 36.

[0031] The plurality of engaging portions 34 include a first engaging portion 341 (one or more first engaging portions 341) and a second engaging portion 342 (one or more second engaging portions 342). The plurality of locking portions 36 include a first locking portion 361 (one or more first locking portions 361) and a second locking portion 362 (one or more second locking portions 362).

[0032] Fig. 4 is a cross-sectional view of the electronic device 10. Fig. 4 shows a cross section taken along line IV-IV in Fig. 2. Fig. 5 is an enlarged view of a portion of Fig. 4. Fig. 5 shows the first engaging portion 341 and the first locking portion 361. Note that the circuit board 22 is not shown in Figs. 4 and 5.

[0033] The first engaging portion 341 includes a first arm portion 38 and a first engaging claw 40 .

[0034] The first arm portion 38 is located outside the internal space of the housing 18. In other words, the first arm portion 38 is located outward from the above-described standing wall portion 28. Therefore, when the housing 18 is configured by combining multiple housing members 26, the first arm portion 38 can be exposed without being shielded from the outside by the standing wall portion 28. The first arm portion 38 protrudes from the housing member 26 along the first direction D1. The first arm portion 38 protrudes from, for example, the second main surface 26s2 of the second housing member 262 along the first direction D1. The first arm portion 38 is flexible.

[0035] The first engagement claw 40 protrudes from the first arm portion 38 toward the inside of the housing 18 (housing member 26). The first engagement claw 40 has a first engagement surface 40s. The first engagement surface 40s is a surface that engages with the first locking portion 361.

[0036] The first locking portion 361 includes a structure (construction) that can engage with the first engagement claw 40 (first engagement surface 40s). For example, as shown in FIG. 5 , the first locking portion 361 may include a protrusion 361A that protrudes from the standing wall portion 28. The first engagement claw 40 engages with the protrusion 361A, thereby engaging the first locking portion 361 and the first engagement portion 341. As shown in FIGS. 2 and 3 , the first locking portion 361 may include a recess (hole) 361B formed in the standing wall portion 28. In this case, the first engagement claw 40 engages with the recess 361B, thereby engaging the first locking portion 361 and the first engagement portion 341. As described above, the standing wall portion 28 is provided on the first housing member 261. Therefore, the first locking portion 361 is provided on the first housing member 261.

[0037] As described above, the first arm portion 38 is positioned outward relative to the second housing member 262. Therefore, the user can operate the first engagement portion 341 to disengage the first engagement portion 341 from the first locking portion 361. That is, the user can disengage the first engagement claw 40 (first engagement surface 40s) from the first locking portion 361 by bending the flexible first arm portion 38. The user may operate the first engagement portion 341 using a predetermined tool (such as a jig).

[0038] The first engagement surface 40s of the first engagement claw 40 extends along a direction perpendicular to the first direction D1. The in-plane direction of the first engagement surface 40s may be perpendicular to the first direction D1.

[0039] The first engagement surface 40s may be inclined so that the dimension (distance) in the first direction D1 between the main surface 26s of the housing member 26 on which the first engagement portion 341 is provided and the first engagement surface 40s of the first engagement portion 341 becomes longer as the surface approaches the tip of the first engagement claw 40. In other words, the first engagement surface 40s may be inclined so that the distance in the first direction D1 between the second main surface 26s2 and the first engagement surface 40s becomes longer as the surface approaches the tip (first claw tip) 40t of the first engagement claw 40.

[0040] In the following description, the gradient GR1 of the first engagement surface 40s with respect to the first direction D1 is also referred to as the “first gradient GR1.” When the first engagement surface 40s extends parallel to a direction perpendicular to the first direction D1, the first gradient GR1 is, for example, 90°, but is not limited to this.

[0041] Fig. 6 is an enlarged view of a portion of Fig. 4. The second engaging portion 342 and the second locking portion 362 are shown in Fig. 6.

[0042] The second engaging portion 342 includes a second arm portion 42 and a second engaging claw 44 .

[0043] [Correction based on Rule 91 09.05.2025] The second arm portion 42 is located inside the housing 18. In other words, the second arm portion 42 is located inward from the standing wall portion 28. Therefore, when the housing 18 is configured by combining multiple housing members 26, the second arm portion 42 is shielded from the outside of the housing 18 by the standing wall portion 28. The second arm portion 42 protrudes from the housing member 26 in the first direction D1. The second arm portion 42 protrudes from, for example, the second main surface 26s2 of the second housing member 262 in the first direction D1. The second arm portion 42 is flexible.

[0044] The second engagement claw 44 protrudes from the second arm portion 42 toward the outside of the housing 18 (housing member 26). The second engagement claw 44 has a second engagement surface 44s. The second engagement surface 44s is a surface that engages with the second locking portion 362.

[0045] The second locking portion 362 includes a structure (construction) that can engage with the second engagement claw 44 (second engagement surface 44s). For example, as shown in FIG. 6 , the second locking portion 362 may include a recess (hole) 362A formed in a wall portion (standing wall portion 28) of the housing 18. The second engagement claw 44 engages with the recess 362A, thereby engaging the second locking portion 362 and the second engagement portion 342. Although not specifically illustrated, the second locking portion 362 may include a protrusion that protrudes from the wall portion (standing wall portion 28). In this case, the second engagement claw 44 engages with the protrusion, thereby engaging the second locking portion 362 and the second engagement portion 342. Note that the protrusion has a shape similar to, for example, the protrusion 361A ( FIG. 5 ), which is the first locking portion 361, but is not limited thereto.

[0046] The second engagement surface 44s is inclined so that the dimension (distance) in the first direction D1 between the main surface 26s of the housing member 26 on which the second engagement portion 342 is provided and the second engagement surface 44s of the second engagement portion 342 becomes longer as it approaches the tip of the second engagement claw 44. In other words, the second engagement surface 44s is inclined so that the distance in the first direction D1 between the second main surface 26s2 and the second engagement surface 44s becomes longer as it approaches the tip (second claw tip) 44t of the second engagement claw 44.

[0047] In the following description, the gradient GR2 of the second engagement surface 44s relative to the first direction D1 is also referred to as the second gradient GR2. The first gradient GR1 and the second gradient GR2 described above are different. More specifically, the second gradient GR2 is smaller than the first gradient GR1 (GR2<GR1). Even more specifically, the second gradient GR2 when the first engagement surface 40s and the first locking portion 361 are engaged and the second engagement surface 44s and the second locking portion 362 are engaged is smaller than the first gradient GR1 in this state ( FIGS. 4 to 6 ). As a result, the first engagement claw 40 relatively firmly locks the second housing member 262 to the first housing member 261, while the second engagement claw 44 relatively weakly locks the second housing member 262 to the first housing member 261.

[0048] The second engagement surface 44s may be flat or curved. That is, the second gradient GR2 may change continuously along the protruding direction of the second engagement claw 44. In this case, too, the first gradient GR1 and the second gradient GR2 may be different. Also in this case, while the first engagement claw 40 relatively firmly engages the second housing member 262 with the first housing member 261, the second engagement claw 44 may relatively weakly engage the second housing member 262 with the first housing member 261.

[0049] The locations of the multiple locking portions 36, including the above-described first locking portion 361 and second locking portion 362, can be determined as appropriate, but it is preferable that the first locking portion 361 be disposed on the first partial wall portion 28p1 that forms the right side wall of the housing 18. It is also preferable that the first locking portion 361 be disposed on the second partial wall portion 28p2 that forms the left side wall of the housing 18. It is also preferable that the second locking portion 362 be disposed on each of the third partial wall portion 28p3 that forms the top wall of the housing 18 and the fourth partial wall portion 28p4 in which the connector exposed portion 30 is formed.

[0050] The electronic device 10 (housing 18) may include one or more identification portions 46 for distinguishing between the first engaging portion 341 and the second engaging portion 342. The one or more identification portions 46 (identification portions 46) may be configured, for example, by irregularities 46A formed on the housing 18 corresponding to the positions of the first engaging portions 341. The identification portions 46 may be configured by coloring (colored portions) applied to the housing 18 corresponding to the positions of the first engaging portions 341. The irregularities 46A, colored portions, etc. may indicate the positions of the first engaging portions 341.

[0051] The electronic device 10 (housing 18) having the above-described configuration exhibits the following advantageous effects, for example.

[0052] The locking structure 32 includes a plurality of engaging portions 34 and a plurality of locking portions 36 that engage with the plurality of engaging portions 34. The second housing member 262 is locked to the first housing member 261 by the engagement of the plurality of engaging portions 34 with the plurality of locking portions 36.

[0053] Furthermore, according to this embodiment, the first gradient GR1 and the second gradient GR2 are different from each other. As a result, one of the first engaging portion 341 and the second engaging portion 342 relatively firmly locks the second housing member 262 to the first housing member 261. In contrast, the other of the first engaging portion 341 and the second engaging portion 342 relatively weakly locks the second housing member 262 to the first housing member 261. For example, the second gradient GR2 is set to be smaller than the first gradient GR1. In this case, the first engaging portion 341 can relatively firmly lock the second housing member 262 to the first housing member 261, while the second engaging claw 44 can relatively weakly lock the second housing member 262 to the first housing member 261.

[0054] Fig. 7A is a diagram showing the second engaging portion 342 and the second locking portion 362. Fig. 7A shows the second engaging portion 342 and the second locking portion 362 when the first housing member 261 and the second housing member 262 are separated. Fig. 7B is a diagram showing the second engaging portion 342 and the second locking portion 362. Fig. 7B shows the first housing member 261 and the second housing member 262 further separated from each other than in the state shown in Fig. 7A.

[0055] According to this embodiment, after disengaging the first engaging portion 341 from the first locking portion 361 using a hand or a tool, the user can disengage the second engaging portion 342 from the second locking portion 362 without directly operating the second engaging portion 342. That is, after disengaging the first engaging portion 341 from the first locking portion 361, the user pulls one of the first housing member 261 and the second housing member 262 away from the other along the first direction D1. This causes the second arm portion 42 to bend due to its flexibility ( FIG. 7A ). Such a second engaging portion 342 is unlikely to hinder the relative movement of the first housing member 261 and the second housing member 262 along the first direction D1. As the first housing member 261 and the second housing member 262 are pulled apart along the first direction D1, the relatively weak engagement between the second engagement portion 342 and the second locking portion 362 can be easily released (Figure 7B).

[0056] When the first engaging portions 341 and the first locking portions 361 are engaged with each other, the first engaging portions 341 and the first locking portions 361 restrict relative movement between the first housing member 261 and the second housing member 262 in the first direction D1. This prevents the second engaging portions 342 and the second locking portions 362 from disengaging from each other. As a result, the second housing member 262 can be maintained in a state in which it is properly locked to the first housing member 261 by the multiple engaging portions 34 and the multiple locking portions 36.

[0057] The first arm portion 38 of the first engagement portion 341 is preferably located outside the internal space of the housing 18. This allows the user to relatively easily operate the first arm portion 38. In this case, the first engagement claw 40 protrudes toward the inside (internal space) of the housing 18, and can thereby engage with the first locking portion 361, which is a part of the housing 18.

[0058] The second arm portion 42 may be located inside the interior space of the housing 18. This, for example, makes it difficult for the user to see the second engagement portion 342. By intentionally not allowing the user to see the second engagement portion 342, it is possible to prevent the user from forcibly operating the second engagement portion 342, which is located in a position that is relatively difficult for the user's fingers or tools to reach, for example. When the second arm portion 42 is located inside the interior space of the housing 18, the second engagement claw 44 protrudes toward the outside of the housing 18. This allows the second engagement claw 44 to engage with the second locking portion 362, which is a part of the housing 18.

[0059] According to the present embodiment, the second engagement surface 44s may be a curved surface. When the second engagement surface 44s is a curved surface, the contact area between the second engagement surface 44s and the second locking portion 362 can be reduced compared to when the second engagement surface 44s is a flat surface. As a result, when the first housing member 261 and the second housing member 262 are pulled apart, the relatively weak engagement between the second engagement portion 342 and the second locking portion 362 can be more easily released because the second engagement surface 44s is a curved surface.

[0060] According to the present embodiment, the housing 18 may be provided with an identification portion 46. This allows the user to easily distinguish between the positions of the first engagement portion 341 and the second engagement portion 342. In other words, the user can easily distinguish between the portions that are operated by the user and the portions that are not operated by the user. The identification portion 46 may be formed by the irregularities 46A, but may also be formed by a colored portion.

[0061] The identification portion 46 is disposed, for example, near the first engagement portion 341 to indicate the location of the first engagement portion 341. This allows the user to easily identify the location of the engagement portion 34 (first engagement portion 341) that should be operated.

[0062] Furthermore, according to the present embodiment, it is preferable that at least one locking portion 36 is provided on each of the plurality of partial wall portions 28p that form the wall portion of the housing 18. This allows the second housing member 262 to be securely locked to the first housing member 261. For example, the formation of an excessive gap between the first housing member 261 and the second housing member 262 can be prevented.

[0063] Moreover, according to this embodiment, a first locking portion 361 is provided on each of two partial wall portions 28p facing each other along the second direction D2. That is, a first locking portion 361 is provided on each of the first partial wall portion 28p1 that forms the right side wall of the housing 18 and the second partial wall portion 28p2 that forms the left side wall of the housing 18. In this case, a user can operate the first engaging portion 341 corresponding to the first locking portion 361 of the first partial wall portion 28p1 with one hand while operating the first engaging portion 341 corresponding to the first locking portion 361 of the second partial wall portion 28p2 with the other hand. That is, the user can relatively easily operate the multiple first engaging portions 341 using both hands. This allows the user to relatively quickly release the engagement between the multiple first locking portions 361 and the multiple first engaging portions 341.

[0064] Furthermore, in this case, the user can smoothly grasp both ends of the second housing member 262 in the second direction D2 with both hands, which allows the user to smoothly start the operation of lifting the second housing member 262 relative to the first housing member 261 after disengaging the first locking portions 361 from the first engaging portions 341.

[0065] On the other hand, the second locking portion 362 may be disposed, for example, on the third partial wall portion 28p3 that forms the upper wall of the housing 18. The third partial wall portion 28p3 that forms the upper wall is located higher than the other partial wall portions 28p and may therefore be difficult for the user to see. In this regard, according to the present embodiment, the user can easily disengage the second locking portion 362 disposed on the third partial wall portion 28p3 from the second engaging portion 342 corresponding to the second locking portion 362 without visually checking the third partial wall portion 28p3.

[0066] The second locking portion 362 may be disposed on the fourth partial wall portion 28p4 on which the connector exposed portion 30 is formed. A connection cable 100 connected to the external connector 24 may be disposed around the connector exposed portion 30. The fourth partial wall portion 28p4 is a partial wall portion 28p that is relatively difficult for a user to touch when the connection cable 100 is disposed thereon. In this regard, according to the present embodiment, the user can easily release the engagement between the second locking portion 362 disposed on the fourth partial wall portion 28p4 and the second engaging portion 342 corresponding to the second locking portion 362 without directly operating the second engaging portion 342. In this case, there is no need to remove the connection cable 100.

[0067] Because the second engagement portion 342 does not need to be directly operated by the user, it may be disposed, for example, in a location on the back 12b of the display device 12 that is hidden behind the peripheral member 16. For example, the second locking portion 362 disposed on the fourth partial wall portion 28p4 is disposed in a location that is hidden behind the peripheral member 16 (see also FIG. 1 ). As described above, the user can easily release the engagement between the second locking portion 362 and the second engagement portion 342 corresponding to the second locking portion 362 without directly operating the second engagement portion 342.

[0068] The second locking portion 362 may be disposed on at least one of the first partial wall portion 28p1 and the second partial wall portion 28p2, or the first locking portion 361 may be disposed on at least one of the third partial wall portion 28p3 and the fourth partial wall portion 28p4. For example, FIGS. 1 and 2 show the first locking portion 361 disposed on the fourth partial wall portion 28p4. The first locking portion 361 is located between two external connectors 24 that are relatively far apart. A first locking portion 361 disposed in this manner can be operated relatively easily by a user.

[0069] One embodiment may be modified as follows. In the following modifications, descriptions that overlap with the embodiment will be omitted as appropriate. In addition, in the drawings used in the following modifications, the same reference numerals are used for the same components as those described in the embodiment.

[0070] (Variation 1) The first engaging portion 341 (at least one first engaging portion 341) may be provided on the first housing member 261. In this case, the first locking portion 361 corresponding to the first engaging portion 341 is provided on the second housing member 262.

[0071] (Modification 2) The first arm portion 38 may be located inside (in the internal space of) the housing 18. In this case, the first engagement claw 40 protrudes from the first arm portion 38 toward the outside of the housing 18.

[0072] Even in this case, it is preferable that the user be able to operate the first engagement portion 341. For example, the first engagement claw 40 may be exposed to the outside of the housing 18. In this case, the user can release the engagement between the first engagement portion 341 and the first locking portion 361 by pushing the first engagement claw 40 exposed to the outside of the housing 18 into the inside of the housing 18.

[0073] (Variation 3) The second engaging portion 342 (at least one second engaging portion 342) may be provided on the first housing member 261. In this case, the second locking portion 362 corresponding to the second engaging portion 342 is provided on the second housing member 262.

[0074] (Modification 4) The second arm portion 42 may be located outside the interior space of the housing 18. In this case, the second engagement claw 44 protrudes from the second arm portion 42 toward the inside of the housing 18.

[0075] (Combination of Multiple Modifications) The multiple modifications described above may be combined as appropriate within a range that does not cause inconsistency.

[0076] According to the above embodiment and modified examples, the user can relatively easily separate the multiple housing members 26 .
