Description

デジタルカメラ等の電子機器では、製造コストや組立作業性の観点から、連結部を介して複数の操作ボタンを連結した操作ボタン群を合成樹脂等で一体に成形するものが知られている。 The electronic apparatus such as a digital camera, from the viewpoint of manufacturing cost and assembling workability is known which integrally molded operation button group which concatenates a plurality of operation buttons through a connecting portion with the synthetic resin or the like.

上記目的を達成するために、本発明の電子機器は、複数の操作ボタンが連結部を介して一体に連結された操作ボタン群と、前記操作ボタンが内面側から嵌め込まれるボタン穴が貫通して形成されたカバー部材と、を備える電子機器であって、前記操作ボタン群は、前記ボタン穴に前記カバー部材の内面側から嵌め込まれる第１の操作ボタンと、前記ボタン穴に前記カバー部材の内面側から嵌め込まれて、前記第１の操作ボタンに近接して並設される第２の操作ボタンと、前記第１の操作ボタンに第１の連結部を介して連結され、前記カバー部材に形成された第１の被嵌合部に位置決め嵌合される第１の嵌合部を有する第１の位置決め部材と、前記第２の操作ボタンに第２の連結部を介して連結されるとともに、弾性変形が可能な第３の連結部を介して前記第１の位置決め部材に連結され、前記カバー部材に形成された第２の被嵌合部に位置決め嵌合される第２の嵌合部を有する第２の位置決め部材と、を備え、前記第１の被嵌合部と前記第２の被嵌合部との間の距離は、前記第１の嵌合部と前記第２の嵌合部との間の距離よりも短く設定されていることを特徴とする。 In order to achieve the above object, an electronic device according to the present invention includes an operation button group in which a plurality of operation buttons are integrally connected via a connecting portion, and a button hole into which the operation button is fitted from the inner surface side. The operation button group includes: a first operation button fitted into the button hole from the inner surface side of the cover member; and an inner surface of the cover member in the button hole. A second operation button that is fitted from the side and arranged in parallel with the first operation button, and is connected to the first operation button via a first connection portion, and is formed on the cover member A first positioning member having a first fitting portion that is positioned and fitted to the first fitted portion, and the second operation button coupled to the second operation button via a second coupling portion; Third connecting part capable of elastic deformation A second positioning member having a second fitting portion coupled to the first positioning member via the second fitting portion and positioned and fitted to a second fitted portion formed on the cover member, the distance between the first fitted portion and the second fitted portion is set shorter than the distance between said first fitting part and the second fitting portion Tei It is characterized by that.

図３に示すように、操作ボタン群４１は、複数の操作ボタンが連結部を介して一体に連結された合成樹脂成形品であり、例えば操作ボタン４０１は、連結部４１２を介して他の操作ボタンに連結されている。 As shown in FIG. 3, the operation button group 41 is a synthetic resin molded product in which a plurality of operation buttons are integrally connected via a connecting portion. For example, the operation button 401 is connected to another operation via the connecting portion 412. It is linked to the button.

操作ボタン群４１は、固定型と可動型との間に形成されるキャビティに溶融した合成樹脂を流し込んで一体に成形される。ここで、操作ボタン群４１の各操作ボタンは、単独で押し操作ができるように互いに離れて配置される必要があるため、成形時には、各操作ボタンの間の連結部を除く部分に、型の肉が存在する。 The operation button group 41 is integrally formed by pouring molten synthetic resin into a cavity formed between a fixed mold and a movable mold. Here, since each operation button of the operation button group 41 needs to be arranged away from each other so that it can be pushed independently, at the time of molding, a portion of the mold is not provided in a portion excluding a connecting portion between the operation buttons. There is meat.

射出成形では、高温で溶融した合成樹脂を高圧力に保つために、各操作ボタンの間の型の肉には十分な厚みを持たせなければならない。このため、成形時の各操作ボタンの間には、一定以上の間隔が必要となる。従って、背面カバー２上で近接して並設される操作ボタン４０２と操作ボタン４０３との間にも、成形時には、一定以上の間隔４４０が設けられている。 In the injection molding, in order to keep the synthetic resin melted at a high temperature at a high pressure, the mold meat between the operation buttons must have a sufficient thickness. For this reason, a certain interval or more is required between the operation buttons at the time of molding. Therefore, a certain interval 440 or more is also provided between the operation buttons 402 and 403 arranged side by side on the back cover 2 at the time of molding.
