After that, the front frame 110 cannot be rotated or the locking portion 221 provided on the housing 220 cannot be rotated to return to the horizontal state.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide an electronic device that can automatically fit and fix the second frame-like body inside the first frame-like body by the work robot. And a manufacturing method thereof.

  In order to solve the above problems, an electronic device according to the present invention includes a first frame-shaped body and a second frame-shaped body, and the second frame-shaped body is fitted inside the first frame-shaped body. In the electronic apparatus, the first frame-shaped body has a first frame-shaped body locking recess formed on an inner surface, and the second frame-shaped body has a fulcrum provided on the second frame-shaped body. And a second frame-shaped body locking portion that is rotatable in a plane that is substantially perpendicular to the inner side surface of the first frame-shaped body and parallel to the insertion direction of the first frame-shaped body. A second frame-like body locking convex portion to be inserted into the first frame-shaped body locking concave portion is formed on the outer surface of the second frame-like body locking portion, and the second frame The outer surface of the locking member is placed on the inner surface of the first frame to avoid the second frame locking protrusion from contacting the inner surface of the first frame when inserted. The second frame is inclined with respect to the second frame. A second frame-shaped body locking portion of the second frame-shaped body, which is relatively inserted in the first frame-shaped body by being translated in parallel with the first frame-shaped body along the inner surface.

It is characterized in that a locking means for locking the shaped body and the second frame-like body is provided.

  In order to solve the above problems, a method for manufacturing an electronic device according to the present invention includes a first frame body and a second frame body, and the second frame body is fitted inside the first frame body. In the electronic device manufacturing method, the second frame-shaped body locking convex portion formed on the outer surface of the second frame-shaped body locking portion formed on the second frame-shaped body is The second frame formed so that the outer surface of the second frame-shaped body locking portion is inclined with respect to the inner surface of the first frame-shaped body so as to avoid contact with the inner surface of the first frame-shaped body. A fitting process for relatively translating the shaped body along the inner side surface of the first frame-like body and fitting it inside the first frame-like body; and after the fitting step, the second frame The second frame-shaped body locking projection is formed on the inner surface of the first frame-shaped body by rotating the second frame-shaped body locking portion around a fulcrum provided on the shape-shaped body. 1 Insert into the frame-shaped body locking recess It is characterized in that it comprises a first frame-like body and by a locking step of locking the second frame-shaped body.

  In the present invention, the first frame-like body and the second frame-like body do not necessarily have the four sides of the frame continuously connected, and may be partially cut off. Moreover, the bottom surface etc. may be provided in the frame.

  According to said invention, the electronic device is provided with the 1st frame-shaped body and the 2nd frame-shaped body, and the 2nd frame-shaped body is inserted by the inner side of the said 1st frame-shaped body. The first frame-like body has a first frame-like body locking recess formed on the inner side surface, and the second frame-like body is locked to the first frame-like body locking recess. The 2nd frame-shaped body latching convex part is provided.

  In such an electronic device and a manufacturing method thereof, when the second frame-like body is fitted inside the first frame-like body, the second frame-like body is parallel to the inner side surface of the first frame-like body. When the second frame-shaped body moves, the second frame-shaped body locking projection formed on the outer surface of the second frame-shaped body comes into contact with the inner side surface of the first frame-shaped body and cannot be moved forward. For this reason, when inserting manually, the state which rotated the whole 2nd frame-like body and avoided that the 2nd frame-like body latching convex part contacts the inner surface of the 1st frame-like body And after inserting, it is easy to rotate the entire second frame-like body in the opposite direction and engage the second frame-like body engaging convex part with the first frame-like body engaging concave part. it can.

  However, when manufacturing automatically with a work robot, the work of turning the entire second frame-like body, inserting it, and then returning it to the horizontal position is not easy.

  Therefore, in the present invention, the second frame-shaped body is substantially perpendicular to the inner surface of the first frame-shaped body with the fulcrum provided on the second frame-shaped body as the center, and the first frame-shaped body. The 2nd frame-shaped body latching | locking part which can be rotated within the surface parallel to the insertion direction to is formed. That is, in the present invention, a second frame-shaped body locking portion is provided in which the entire second frame-shaped body is not rotated, but a part of the second frame-shaped body is formed to be rotatable. And the 2nd frame-shaped body latching convex part inserted in a 1st frame-shaped body latching recessed part is formed in the outer surface of this 2nd frame-shaped body latching | locking part. Furthermore, in the present invention, the outer surface of the second frame-shaped body locking portion is in a state before being inserted, and the second frame-shaped body locking convex portion is in contact with the inner surface of the first frame-shaped body at the time of insertion. In order to avoid this, it is formed to be inclined with respect to the inner surface of the first frame-like body.

  Therefore, the work robot can easily fit the second frame-like body inside the first frame-like body by relatively translating the second frame-like body along the inner surface of the first frame-like body in the insertion step. Can be inserted.

  Next, in the present invention, since the outer surface of the second frame-shaped body locking portion is formed to be inclined with respect to the inner surface of the first frame-shaped body, the second frame-shaped body locking convex portion is the first frame. In order to lock the frame-shaped body locking recess, rotate the second frame-shaped body so that the outer surface of the second frame-shaped body locking portion is parallel to the inner surface of the first frame-shaped body. Must move.

  Therefore, in the present invention, only the second frame-shaped body locking portion that is a part of the second frame-shaped body is rotated. Specifically, in the locking step, the second frame-shaped body locking portion is rotated about the fulcrum provided in the second frame-shaped body using the locking means, and the second frame is rotated by this rotation. The frame-like body locking projection is inserted into a first frame-like body locking recess formed on the inner surface of the first frame-like body. As a result, the first frame-shaped body and the second frame-shaped body can be locked and fitted and fixed.

  Therefore, it is possible to provide an electronic device that can automatically fit and fix the second frame-like body inside the first frame-like body by the work robot, and a manufacturing method thereof.

  In the electronic device of the present invention, the second frame-shaped body locking portion is formed at an outer end portion of the second frame-shaped body and is inclined with respect to the inner side surface of the first frame-shaped body. The L-shaped cross-section comprising an inverted L-shaped upper surface portion and an inverted L-shaped hanging portion orthogonal to the inverted L-shaped upper surface portion is flexible, and the locking means includes: In one frame-like body, a support surface provided substantially perpendicular to the inner side surface of the first frame-like body, and the surface of the inverted L-shaped hanging portion that is inclined and abutted against the support surface when fitted are inserted into the support surface. The second frame-like body locking portion is rotated and fixed so that the second frame-like body locking projection is inserted into the first frame-shaped body locking concave portion. It can be said that it consists of the fixing member which latches a 1st frame-shaped body and a 2nd frame-shaped body.

  According to said invention, the 2nd frame-shaped body latching | locking part is formed in the outer side edge part of the 2nd frame-shaped body, and the reverse L formed inclining with respect to the inner surface of a 1st frame-shaped body. It is flexible in the shape of a reverse L-shaped cross section comprising a character upper surface portion and an inverted L-shaped drooping portion orthogonal to the inverted L-shaped upper surface portion. That is, in this invention, since the outer side edge part of the 2nd frame-shaped body is a 2nd frame-shaped body latching | locking part, and it has flexibility, it is the 2nd frame which consists of a cross-section reverse L-shape. If a one-point concentrated load is applied to the inverted L-shaped hanging portion of the shaped body locking portion, the inverted L-shaped hanging portion bends with respect to the second frame-shaped body.

  Therefore, in the present invention, as the locking means, in the first frame-shaped body, a support surface provided substantially perpendicular to the inner surface of the first frame-shaped body, and a reverse contact that is inclined and abutted on the support surface when inserted. The surface of the L-shaped hanging part is fastened and fixed so as to be parallel to the support surface, whereby the second frame-shaped body locking portion is rotated and the second frame-shaped body locking convex portion is moved to the first frame-shaped body. A fixing member is provided that is inserted into the locking recess to lock the first frame-shaped body and the second frame-shaped body.

  Thus, for example, by using a fixing member such as a screw, by fastening the reverse L-shaped hanging portion obliquely contacting the support surface provided substantially perpendicular to the inner surface of the first frame-like body, The inverted L-shaped drooping portion bends and rotates, and the inverted L-shaped upper surface portion rotates with the rotation of the inverted L-shaped drooping portion. As a result, the second frame-shaped body locking convex portion formed on the outer surface of the inverted L-shaped upper surface portion is inserted into the first frame-shaped body locking concave portion, and the first frame-shaped body, the second frame-shaped body, Can be locked.

  In the electronic device according to the aspect of the invention, the second frame-shaped body locking portion is provided at an outer end of the second frame-shaped body, and is formed to be inclined with respect to the inner surface of the first frame-shaped body. An inverted L-shaped cross-section that is formed of an inverted L-shaped upper surface portion and an inverted L-shaped hanging portion orthogonal to the inverted L-shaped upper surface portion and is hinge-coupled at the fulcrum, which is a separate member from the second frame-shaped body The locking means includes a support surface provided substantially perpendicular to the inner surface of the first frame-like body in the first frame-like body, and is inclined to the support surface when inserted. By fastening and fixing the surface of the abutting L-shaped hanging portion that is in contact with the support surface in parallel, the second frame-shaped body locking portion is rotated to rotate the second frame-shaped body locking protrusion. It can be assumed that the first frame-shaped body locking recess is inserted into the first frame-shaped body locking recess to fix the first frame-shaped body and the second frame-shaped body.

  According to said invention, a 2nd frame-shaped body latching | locking part is provided in the outer side edge part of the 2nd frame-shaped body, and is the reverse L character formed inclining with respect to the inner surface of a 1st frame-shaped body. An inverted L-shaped member having a cross-section that is a separate member from the second frame-like member, which is composed of an upper surface portion and an inverted L-shaped hanging portion orthogonal to the inverted L-shaped upper surface portion, and is hinged at the fulcrum. It has become. Thus, in the present invention, the second frame-shaped body locking portion is made of a T-shaped member having a different cross-section from the second frame-shaped body, and the second frame-shaped body locking portion is the second frame. It is hinge-coupled to a fulcrum provided on the rod-like body, and is rotatable with respect to the second frame-like body around the fulcrum. For this reason, if a one-point concentrated load is applied to the inverted L-shaped hanging portion of the second frame-shaped body locking portion made of the T-shaped member in cross section, the inverted L-shaped hanging portion rotates relative to the second frame-shaped body. .

  Therefore, in the present invention, as the locking means, the first frame-like body has a support surface provided substantially perpendicular to the inner surface of the first frame-like body, and is in contact with the support surface in an inclined manner when inserted. By fastening and fixing the surface of the inverted L-shaped hanging portion so as to be parallel to the support surface, the second frame-shaped body locking projection is rotated to rotate the second frame-shaped body locking projection. A fixing member is provided that is inserted into the first frame-shaped body locking recess to lock the first frame-shaped body and the second frame-shaped body.

  Thereby, by using, for example, a fixing member such as a screw, by fastening so that the inverted L-shaped hanging portion obliquely contacting the support surface provided substantially perpendicular to the inner surface of the first frame-like body is in pressure contact, The inverted L-shaped drooping portion rotates about the fulcrum, and the inverted L-shaped upper surface portion rotates with the rotation of the inverted L-shaped drooping portion. As a result, the second frame-shaped body locking convex portion formed on the outer surface of the inverted L-shaped upper surface portion is inserted into the first frame-shaped body locking concave portion, and the first frame-shaped body, the second frame-shaped body, Can be locked.

  In the electronic device according to the aspect of the invention, the second frame-shaped body locking portion is provided at an outer end of the second frame-shaped body, and is formed to be inclined with respect to the inner surface of the first frame-shaped body. It is composed of a T-shaped member having a T-shaped upper surface portion and a T-shaped hanging portion orthogonal to the T-shaped upper surface portion, and is a T-shaped member having a different cross section from the second frame-like body hinged at the fulcrum. The locking means includes a support surface provided substantially perpendicular to an inner surface of the first frame-like body in the first frame-like body, and the T-shape which is in contact with the support surface in an inclined manner when inserted. By contacting the surface of the hanging portion so as to be parallel to the support surface, the second frame-shaped body locking portion is rotated, and the second frame-shaped body locking convex portion is moved to the first frame-shaped body. The first frame-shaped body and the second frame-shaped body are locked by being inserted into the locking recess, and the play formed on the second frame-shaped body so as to loosely fit one end of the T-shaped upper surface portion. Fitting It can be made up of the.

It is hinge-coupled to a fulcrum provided on the rod-like body, and is rotatable with respect to the second frame-like body around the fulcrum. For this reason, if a one-point concentrated load is applied to the T-shaped hanging portion of the second frame-shaped body locking portion formed of the T-shaped member in cross section, the T-shaped hanging portion rotates with respect to the second frame-shaped body.

  Therefore, in the present invention, as the locking means, the support surface provided substantially perpendicular to the inner surface of the first frame-like body in the first frame-like body, and the T which is in contact with the support surface in an inclined manner when inserted. By bringing the surface of the lower part into contact with the support surface so as to be parallel to the support surface, the second frame-like body engaging portion is rotated so that the second frame-like body engaging convex portion is engaged with the first frame-like body.

And a hole.

  As a result, the T-shaped hanging portion is rotated about the fulcrum by pressing the T-shaped hanging portion that is obliquely in contact with the support surface provided substantially perpendicular to the inner side surface of the first frame-like body. The T-shaped upper surface portion rotates with the rotation of the lower part of the character. As a result, the first frame-shaped body and the second frame-shaped body are inserted by inserting the second frame-shaped body locking convex portion formed on the outer surface of the T-shaped upper surface portion into the first frame-shaped body locking concave portion. It can be locked. Further, when the T-shaped upper surface portion rotates, one end portion of the T-shaped upper surface portion is loosely fitted in a loose fitting hole formed in the second frame-shaped body.

  As a result, the reverse rotation of the T-shaped upper surface portion is suppressed by loosely fitting one end of the T-shaped upper surface portion into the loose fitting hole formed in the second frame-shaped body.

  Therefore, it is possible to maintain a state in which the second frame body is fitted and fixed inside the first frame body.

  In the electronic device according to the present invention, the locking means is fastened and fixed so that the surface of the T-shaped hanging portion that is inclined and abutted against the support surface is parallel to the support surface when inserted. The second frame-shaped body locking portion is rotated to insert the second frame-shaped body locking convex portion into the first frame-shaped body locking concave portion, and the first frame-shaped body and the second frame-shaped body. It is preferable to further include a fixing member that locks.

  That is, one end portion of the T-shaped upper surface portion is loosely fitted in the loose fitting hole formed in the second frame-like body, thereby suppressing the reverse rotation of the T-shaped upper surface portion. There is a risk of becoming insufficient.

  Therefore, in the present invention, the fixing member is used to fasten and fix the surface of the T-shaped drooping portion inclined and contacting the support surface so as to be parallel to the support surface at the time of insertion. The frame-shaped body locking portion is rotated to insert the second frame-shaped body locking convex portion into the first frame-shaped body locking concave portion to lock the first frame-shaped body and the second frame-shaped body. .

  Accordingly, for example, by using a fixing member such as a screw, the T-shaped hanging portion that is obliquely in contact with the support surface provided substantially perpendicular to the inner side surface of the first frame-like body is fastened so as to be in pressure contact. The character-lowering portion rotates around the fulcrum, and the T-shaped upper surface portion rotates with the rotation of the T-shaped drooping portion. As a result, the first frame-shaped body and the second frame-shaped body are inserted by inserting the second frame-shaped body locking convex portion formed on the outer surface of the T-shaped upper surface portion into the first frame-shaped body locking concave portion. It can be locked.

  Moreover, it becomes possible to maintain reliably the state which fitted and fixed the 2nd frame-shaped body inside the 1st frame-shaped body by the fastening fixation of the fixing member.

An attachment structure between the front frame 2 and the back cover 30 in the liquid crystal display device 10 of the present embodiment will be described with reference to FIGS. 1 (a), (b), (c) and FIG. FIG. 1A is a cross-sectional view showing a main configuration of the liquid crystal display device 10, and FIG. 1B is a cross-sectional view showing a state in which the back cover 30 is fitted inside the front frame 2 in the liquid crystal display device 10. (C) is sectional drawing which shows the state which inserted the back cover 30 inside the front frame 2, and latched and fixed. FIG. 4 is a longitudinal sectional view showing the overall configuration of the liquid crystal display device 10.

  As shown in FIG. 1A, the liquid crystal display device 10 according to the present embodiment includes a front frame 2 as a first frame body and a back cover 30 as a second frame body. A back cover 30 is fitted inside. The front frame 2 is formed with a frame recess 2b as a first frame-like body locking recess on the inner surface 2a. Further, the outer surface 31c of the back cover 30 is provided with a cover convex portion 31d as a second frame-shaped member locking convex portion that is locked to the frame concave portion 2b.

  In such a liquid crystal display device 10 as an electronic apparatus and its manufacturing method, when the back cover 30 is fitted inside the front frame 2, the back cover 30 is translated along the inner side surface 2 a of the front frame 2. When this is done, the cover convex portion 31d formed on the outer side surface 31c of the back cover 30 contacts the inner side surface 2a of the front frame 2 and cannot be moved forward. In particular, when the front frame 2 is not a synthetic resin but a rigid body such as aluminum (Al), it is impossible to move forward when the cover convex portion 31d contacts the inner side surface 2a of the front frame 2. It is.

  For this reason, when manually inserting the back cover 30 inside the front frame 2, the entire back cover 30 is rotated counterclockwise in FIG. It is made to insert in the state which avoided contacting the inner surface 2a of 2. As shown in FIG. Then, after the insertion, the entire back cover 30 is rotated clockwise in the reverse direction, and the cover convex portion 31d is locked to the frame concave portion 2b. Thus, this operation can be easily performed manually.

  However, when the liquid crystal display device 10 is automatically manufactured by the work robot, it is not easy to rotate the entire back cover 30 and insert it back into the horizontal position. That is, even if a program for changing the operation of the work robot is developed, it is not easy to rotate the entire back cover 30 when the back cover 30 is large.

  Therefore, in the present embodiment, the back cover 30 is fitted to the front frame 2 so as to be substantially perpendicular to the inner surface 2a of the front frame 2 around the fulcrum 31e provided on the back cover 30. A cover locking portion 31 is formed as a second frame-shaped body locking portion that can be rotated in a plane parallel to the direction. Note that the rotation surface of the cover locking portion 31 is not necessarily perpendicular to the inner side surface 2a of the front frame 2, but may be substantially perpendicular as described above.

  In other words, in the present embodiment, the cover engaging portion 31 that is formed so that a part of the back cover 30 can be rotated is provided instead of rotating the entire back cover 30. And the cover convex part 31d inserted in the frame recessed part 2b is formed in the outer surface 31c of this cover latching | locking part 31. As shown in FIG.

  Specifically, as shown in FIG. 1A, the cover locking portion 31 is formed at the outer end portion of the back cover 30 and is inclined with respect to the inner side surface 2 a of the front frame 2. It is flexible in the shape of an inverted L-shaped cross section comprising an inverted L-shaped upper surface portion 31a and an inverted L-shaped hanging portion 31b orthogonal to the inverted L-shaped upper surface portion 31a.

  In addition, the outer side surface 31c of the cover locking portion 31 has an inner side surface 2a of the front frame 2 in order to avoid the cover convex portion 31d from coming into contact with the inner side surface 2a of the front frame 2 at the time of insertion before the insertion. It is formed to be inclined with respect to.

  That is, in the present embodiment, as shown in FIG. 4, the back cover 30 is provided with both outer end portions bent inward. As a result, the outer surface 31 c of the cover locking portion 31 is inclined with respect to the inner surface 2 a of the front frame 2. Thus, in the present embodiment, only the cover locking portion 31 is slightly bent, and the central portion of the back cover 30 is a flat surface. However, the present invention is not limited to this, and for example, the entire back cover 30 can be curved.

  With this configuration, as shown in FIG. 1B, the back cover 30 can be easily moved inside the front frame 2 by relatively moving the back cover 30 along the inner side surface 2 a of the front frame 2 with a work robot. It can be inserted.

  Here, as described above, in the present embodiment, the outer surface 31 c of the cover locking portion 31 is formed to be inclined with respect to the inner surface 2 a of the front frame 2. Therefore, after the back cover 30 is fitted inside the front frame 2, the outer surface 31 c of the cover locking portion 31 is the inner surface of the front frame 2 in order to lock the cover convex portion 31 d to the frame concave portion 2 b. The back cover 30 must be rotated so as to be parallel to 2a. However, it is difficult to rotate the entire back cover 30.

  Therefore, in the present embodiment, only the cover locking portion 31 that is a part of the back cover 30 is rotated. Specifically, the cover locking portion 31 is rotated about the fulcrum 31e of the back cover 30 by using the locking means, and this rotation causes the cover convex portion 31d as shown in FIG. 1 (c). Is inserted into a frame recess 2b formed on the inner side surface 2a of the front frame 2. As a result, the front frame 2 and the back cover 30 can be locked and fitted and fixed.

  Here, an example of the locking means will be described below.

  As described above, in the present embodiment, the cover locking portion 31 is formed at the outer end portion of the front frame 2 and is formed to be inclined with respect to the inner side surface 2a of the front frame 2. The section 31a and the inverted L-shaped hanging part 31b orthogonal to the inverted L-shaped upper surface part 31a are flexible in the shape of an inverted L-shaped cross section. In other words, in the present embodiment, the outer end portion of the back cover 30 is the cover locking portion 31 and has flexibility. For this reason, if a one-point concentrated load is applied to the inverted L-shaped hanging portion 31 b of the cover locking portion 31 having an inverted L-shaped cross section, the inverted L-shaped hanging portion 31 b bends with respect to the back cover 30.

  Therefore, in the present embodiment, as the locking means, the front frame 2 has a support surface 22a provided substantially perpendicular to the inner side surface 2a of the front frame 2 and is in contact with the support surface 22a at the time of insertion. By fastening and fixing the surface of the inverted L-shaped hanging portion 31b so as to be parallel to the support surface 22a, the cover locking portion 31 is rotated, and the cover convex portion 31d is inserted into the frame concave portion 2b, whereby the front frame 2 And a fixing screw 32 for locking the rear cover 30 to each other. The support surface 22a is provided with a screwing hole 22b for screwing the fixing screw 32, and a through hole 31f through which the fixing screw 32 is passed is formed in the inverted L-shaped hanging part 31b. . Further, since the front frame 2 is supported by the backlight chassis 22, the support surface 22 a of the backlight chassis 22 can be regarded as an integral part of the front frame 2. Further, the support surface 22a is not necessarily provided perpendicular to the inner side surface 2a of the front frame 2, and may be substantially vertical.

  As a result, as shown in FIGS. 1B and 1C, using the fixing screw 32, the inverted L-shaped drooping slantly contacting the support surface 22a provided substantially perpendicular to the inner surface 2a of the front frame 2 By fastening the portion 31b so as to be in pressure contact, the inverted L-shaped hanging portion 31b bends and pivots about the fulcrum 31e, and the inverted L-shaped upper surface portion 31a moves along with the rotation of the inverted L-shaped hanging portion 31b. Rotate. As a result, the cover convex portion 31d formed on the outer surface 31c of the inverted L-shaped upper surface portion 31a can be inserted into the frame concave portion 2b so that the front frame 2 and the rear cover 30 can be locked.

  The manufacturing method of the liquid crystal display device 10 according to the present embodiment is a manufacturing method of the liquid crystal display device 10 that includes the front frame 2 and the back cover 30, and the back cover 30 is fitted inside the front frame 2. is there. Then, the cover locking portion 31d is formed so as to prevent the cover convex portion 31d formed on the outer side surface 31c of the cover locking portion 31 formed on the back cover 30 from contacting the inner side surface 2a of the front frame 2 at the time of insertion. The front frame 2 is formed by inclining the outer side surface 31c of the front side frame 31 with respect to the inner side surface 2a of the front frame 2 and relatively translating along the inner side surface 2a of the front frame 2. 2 is inserted into the inner side of the front cover 2, and after the insertion step, the cover engaging portion 31 is turned around the fulcrum 31e of the back cover 30 to turn the cover convex portion 31d into the inner side surface 2a of the front frame 2. And a locking step of locking the front frame 2 and the back cover 30 by being inserted into the frame recess 2b formed in the above.

  Therefore, it is possible to provide the liquid crystal display device 10 that can automatically fit and fix the back cover 30 inside the front frame 2 by the work robot, and a manufacturing method thereof.

  In this case, when the liquid crystal display device 10 is recycled, the front frame 2 and the back cover 30 can be easily disassembled by removing the fixing screw 32.

  In addition, this invention is not limited to said embodiment, A various change is possible within the scope of the present invention. For example, in the above embodiment, the first frame body is described as the front frame 2, and the second frame body is described as the back cover 30, but the present invention is not particularly limited thereto. One frame-like body can be the back cover 30 and the second frame-like body can be the front frame 2.

  As described above, in the present embodiment, the cover locking portion 40 is made of a T-shaped member having a cross section different from the back cover 30, and the cover locking portion 40 is a fulcrum 33 provided on the back cover 30. And is pivotable with respect to the back cover 30 around the fulcrum 33. For this reason, if a one-point concentrated load is applied to the inverted L-shaped hanging portion 42 of the cover locking portion 40 made of a member having an inverted L-shaped cross section, the inverted L-shaped hanging portion 42 rotates with respect to the back cover 30.

  Therefore, in the present embodiment, as the locking means, the front frame 2 is inclined to the support surface 22a of the backlight chassis 22 provided substantially perpendicular to the inner surface 2a of the front frame 2 and the support surface 22a when inserted. Then, by fastening and fixing the surface of the inverted L-shaped hanging portion 42 in contact with the support surface 22a, the cover locking portion 40 is rotated to serve as the second frame-shaped body locking convex portion. A fixing screw 32 for locking the front frame 2 and the back cover 30 by inserting the cover convex portion 41b into the frame concave portion 2b is provided.

  As a result, as shown in FIGS. 5B and 5C, using the fixing screws 32, the inverted L-shaped drooping slantly contacting the support surface 22a provided substantially perpendicular to the inner surface 2a of the front frame 2 is performed.

To do. Therefore, the front frame 2 and the back cover 30 can be locked by inserting the cover convex portion 41b formed on the outer surface 41a of the inverted L-shaped upper surface portion 41 into the frame concave portion 2b.

[Embodiment 3]
The following will describe another embodiment of the present invention with reference to FIGS. The configurations other than those described in the present embodiment are the same as those in the first embodiment and the second embodiment. For convenience of explanation, members having the same functions as those shown in the drawings of Embodiment 1 and Embodiment 2 are given the same reference numerals, and explanation thereof is omitted.

  The second frame-like body locking portion of the liquid crystal display device 10 according to the second embodiment is an inverted L-shaped member having a different cross section from the back cover 30 serving as the second frame-like body. However, in the liquid crystal display device 10 according to the present embodiment, as shown in FIGS. 6A, 6 </ b> B, and 6 </ b> C, the second frame-shaped body locking portion is provided with the back cover 30 as the second frame-shaped body. Is different in that it is a member having a T-shaped cross section of another member.

  That is, in the liquid crystal display device 10 as the electronic apparatus in the present embodiment, as shown in FIG. 6A, the cover locking portion 50 as the second frame locking portion is the outer end of the back cover 30. And a T-shaped upper surface portion 51 that is inclined with respect to the inner surface 2a of the front frame 2 as the first frame-like body and a T-shaped hanging portion 52 that is orthogonal to the T-shaped upper surface portion 51. The cross section is a T-shaped member. The cover locking portion 50 is hinged at a fulcrum 33 provided on the back cover 30 and is a separate member from the back cover 30.

  The backlight chassis 22 supported by the front frame 2 is provided with a support surface 22a formed substantially perpendicular to the inner surface 2a of the front frame 2. Further, the back cover 30 is provided with a loose fitting hole 34 for loosely fitting one end of the T-shaped upper surface portion 51.

  Thus, in the present embodiment, the cover locking portion 50 is made of a T-shaped member having a different cross section from the back cover 30, and the cover locking portion 50 is a fulcrum 33 provided on the back cover 30. And is pivotable with respect to the back cover 30 around the fulcrum 33. For this reason, if a one-point concentrated load is applied to the T-shaped hanging portion 52 of the cover locking portion 50 made of a T-shaped member, the T-shaped hanging portion 52 rotates with respect to the back cover 30.

  Therefore, in the present embodiment, as the locking means, the front frame 2 has a support surface 22a provided substantially perpendicular to the inner side surface 2a of the front frame 2 and is in contact with the support surface 22a at the time of insertion. By contacting the surface of the T-shaped hanging portion 52 so as to be parallel to the support surface 22a, the cover locking portion 50 is rotated so that the cover convex portion 51b as the second frame-shaped body locking convex portion is the first. It is formed in the back cover 30 so that the front frame 2 and the back cover 30 are locked by being inserted into the frame recess 2b as a frame-like body locking recess, and one end of the T-shaped upper surface 51 is loosely fitted. A loose fitting hole 34 is provided.

  Accordingly, as shown in FIGS. 6B and 6C, the T-shaped hanging portion 52 that is obliquely in contact with the support surface 22a provided substantially perpendicular to the inner side surface 2a of the front frame 2 is pressed, so that T The character-lowering portion 52 rotates about the fulcrum 33, and the T-shaped upper surface portion 51 rotates with the rotation of the T-shaped hanging portion 52. As a result, the cover convex portion 51b formed on the outer side surface 51a of the T-shaped upper surface portion 51 is inserted into the frame concave portion 2b as the first frame-like body locking concave portion, and the front frame 2 and the rear cover 30 are locked. be able to. Further, when the T-shaped upper surface portion 51 rotates, one end portion of the T-shaped upper surface portion 51 is loosely fitted in the loose fitting hole 34 formed in the back cover 30.

  As a result, the rotation of the T-shaped upper surface portion 51 in the reverse direction, that is, the counterclockwise rotation in FIG. 6B, is a loose fit in which one end of the T-shaped upper surface portion 51 is formed on the back cover 30. It is suppressed by loosely fitting into the hole 34.

  As a result, it is possible to maintain a state in which the back cover 30 is fitted and fixed inside the front frame 2.

  By the way, in the above-described rotation suppression by loosely fitting one end portion of the T-shaped upper surface portion 51 into the loose fitting hole 34, there is a possibility that the engagement between the two ends becomes insufficient.

  Therefore, the liquid crystal display device 10 of the present embodiment includes the fixing screw 32 as the fixing member described in the second embodiment, as shown in FIGS. 7 (a), (b), and (c). It is preferable to keep it.

  That is, by using the fixing screw 32, the cover is locked by fastening and fixing the surface of the T-shaped hanging portion 52 that is inclined and abutted to the support surface 22a so as to be parallel to the support surface 22a. By rotating the part 50, the cover convex part 51b is inserted into the frame concave part 2b, and the front frame 2 and the back cover 30 are locked.

  As a result, the fixing screw 32 is used to fasten the T-shaped hanging portion 52 obliquely contacting the support surface 22a provided substantially perpendicular to the inner side surface 2a of the front frame 2 so as to be in pressure contact with the support surface 22a. The hanging part 52 rotates around the fulcrum, and the T-shaped upper surface part 51 rotates as the T-shaped hanging part 52 rotates. As a result, the front frame 2 and the back cover 30 can be locked by inserting the cover convex portion 51b formed on the outer surface 51a of the T-shaped upper surface portion 51 into the frame concave portion 2b.

  Further, the fastening and fixing of the fixing screw 32 makes it possible to reliably maintain the state in which the back cover 30 is fitted and fixed inside the front frame 2.

  In the above description, the loose fitting hole 34 is described as merely loosely fitting one end of the T-shaped upper surface portion 51 when the T-shaped upper surface portion 51 is rotated. However, the present invention is not limited to this, and as shown in FIGS. 6A, 6B, 7C, 7A, 7B, and 7C, for example, a hook claw is hooked on the tip of one end of the T-shaped upper surface portion 51. Can be formed. Accordingly, it is possible to suppress the disengagement between the front frame 2 and the back cover 30 without providing the fixing screw 32. In this case, once locked by the hooking claw, it is difficult to release the locking. In that case, as shown in FIGS. 6 (a), (b), (c) and FIGS. 7 (a), (b), and (c), the loose fitting hole 34 is set as a through hole, and a rod or the like is inserted from the opening. Thus, the hooking claw can be unlocked.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the technical means disclosed in different embodiments can be appropriately combined.
