Description

  The present invention relates to a display member support structure that is provided in a part of a casing of an electronic device and supports a plate-like display member provided in the electronic device, and an electronic device including the display member support structure.

  Many electronic devices in recent years include a display member for presenting information to a user. A typical example of the display member is a liquid crystal panel having a plate shape. Most liquid crystal panels are attached to electronic equipment cabinets and covered with transparent panels.

  However, once the liquid crystal panel is covered with a transparent panel, there is a problem that it is difficult to repair or replace the liquid crystal panel. In particular, in a configuration in which the liquid crystal panel is supported by a holder integrated with the cabinet, it is difficult to repair or replace the liquid crystal panel after the cover is covered with the transparent panel.

In view of this, some conventional techniques employ a configuration in which the holder that supports the liquid crystal panel can be separated from the cabinet and can be attached to the cabinet again (see, for example, Patent Document 1). In this configuration, the liquid crystal panel is removed from the cabinet together with the holder, so that the liquid crystal panel can be replaced or repaired even after it is covered with a transparent panel.

In this way, the liquid crystal panel 10 is supported by the frame body 50 that is securely fixed to the upper cabinet 4 at a predetermined position, and the liquid crystal panel 10 is also positioned in the frame body 50. Position accuracy can be improved.

  An example in which the liquid crystal panel 10 is introduced from the outside into the frame 50 will be described with reference to FIGS. 4 (A) and 4 (B). The liquid crystal panel 10 is introduced into the frame 50 through the first opening 53. Further, the liquid crystal panel 10 is placed on the first end 55A while pushing away the ribs 52A, 52B, and 52C. At this time, the ribs 52 </ b> A, 52 </ b> B, 52 </ b> C are bent by the amount pressed by the liquid crystal panel 10. The liquid crystal panel 10 placed on the first end 55A is pressed against the reference surfaces 51A and 51B by the action of the restoring force of the ribs 52A, 52B and 52C. The movement of the liquid crystal panel 10 in the front-rear direction and the left-right direction is restricted by the ribs 52A, 52B, 52C and the reference surfaces 51A, 51B. Further, the vertical movement of the liquid crystal panel 10 is restrained by being sandwiched between the first end portion 55A and the hook portion 56.

  As a result, as shown in FIG. 4B, the liquid crystal panel 10 is held at an accurate position in the frame 50. By positioning the liquid crystal panel 10 so as to be pressed against the reference surfaces 51A and 51B, the liquid crystal panel 10 can be held at the same position even if an error occurs in the dimensions of the liquid crystal panel 10. For this reason, even if a dimensional error of about ± 1 mm occurs in the size of the liquid crystal panel 10, the position of the liquid crystal panel 10 does not deviate from the specified position.

  After the attachment of the liquid crystal panel 10 is completed, the liquid crystal panel 10 is covered with a transparent panel 11 as shown in FIG. Here, the transparent panel 11 is fixed to the display member support portion 5 via an adhesive. However, the fixing method of the transparent panel 11 is not limited to the adhesive, and the transparent panel 11 may be fixed by other methods.

  FIG. 6 shows a state in which the upper cabinet 4 is viewed from the inside. As shown in FIG. 6, the frame body 50 includes a second opening 57. The shape and size of the second opening 57 are determined so that the liquid crystal panel 10 can pass therethrough. The second opening 57 opens the internal space of the frame 50 to the inside of the telephone body 1.

  When removing the liquid crystal panel 10 from the frame 50, first, by applying a force to the liquid crystal panel 10, the first end 55A, the hook 56, the reference surfaces 51A, 51B, and the ribs 52A, 52B, 52C are used. Release constraints. Subsequently, the liquid crystal panel 10 is pulled out to the inside of the upper cabinet 4 through the second opening 57. For this reason, the liquid crystal panel 10 can be removed from the frame 50 even after the transparent panel 11 is fixed to the display member support 5.

  Furthermore, the second opening 57 can also be used when the liquid crystal panel 10 is attached from the inside of the upper cabinet 4. Even when the liquid crystal panel 10 is attached from the inside of the upper cabinet 4, the first end 55A, the hook 56, the reference surfaces 51A, 51B, and the ribs 52A, 52B, 52C are surely positioned. The liquid crystal panel 10 can be disposed at an accurate position. As described above, since the liquid crystal panel 10 can be attached from either the upper side or the lower side, the degree of freedom in attaching the liquid crystal panel 10 is increased, and as a result, the work efficiency can be improved.

  The frame body 50 preferably includes a third opening 58. In the present embodiment, the shape and dimensions of the third opening 58 are determined so that the connector 32 of the panel substrate 3 passes through. Furthermore, it is preferable that the connector 32 is exposed in the frame body 50 through the third opening 58 in a state where the panel substrate 3 and the upper cabinet 4 are overlapped. This is realized by arranging the panel substrate 3 and the display member support portion 5 close to each other and arranging the third opening 58 at a position corresponding to the connector 32. In this case, the liquid crystal panel 10 can be easily connected to the connector 32 from the outside even after the lower cabinet 2, the panel board 3, and the upper cabinet 4 are assembled. Here, the configuration in which the third opening 58 and the second opening 57 are continuous is shown here, but the third opening 58 and the second opening 57 may be provided separately. .

  Adopting a configuration in which the connector 32 is exposed in the frame 50 is also useful when the transparent panel 11 and the liquid crystal panel 10 are exchanged at the same time. That is, since the connector 32 is exposed in the frame 50, the liquid crystal panel 10 can be easily removed from the connector from the outside. As a result, it is possible to improve work efficiency when the transparent panel 11 and the liquid crystal panel 10 are simultaneously replaced.

  Finally, the description of the above-described embodiment is to be considered in all respects as illustrative and not restrictive. The scope of the present invention is shown not by the above embodiments but by the claims. Furthermore, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
