本発明は、デジタルカメラや携帯電話等の電子機器の筐体構造に関し、詳しくは、第１ケースには内側の側面から突出する係合爪を設け、第２ケースには側面から薄板状に延在して表面に前記係合爪を嵌入する開口穴を有した係合リブを設け、前記係合爪を前記開口穴に嵌入することによって前記第１ケースと前記第２ケースとを嵌合して内部に所定の部品を収納する電子機器の筐体構造に関する。   The present invention relates to a housing structure of an electronic device such as a digital camera or a mobile phone. Specifically, the first case is provided with an engaging claw protruding from the inner side surface, and the second case extends from the side surface in a thin plate shape. An engagement rib having an opening hole for fitting the engagement claw on the surface is provided, and the first case and the second case are fitted by fitting the engagement claw into the opening hole. In particular, the present invention relates to a housing structure of an electronic device that houses predetermined components therein.

この種の電子機器の筐体構造では、従来、係合爪を開口穴に直接嵌入することによって第１ケースと第２ケースとを嵌合させていた。
特開２０００−３３２４４８号公報 In this type of electronic device casing structure, the first case and the second case are conventionally fitted by directly fitting the engaging claws into the opening hole.
JP 2000-332448 A

この種の電子機器の筐体構造では、係合リブを有する第２ケースに外力が加わることによって係合爪と開口穴との嵌合が外れてしまい、内部に収納されている部材によって第１ケースと第２ケースは開く方向に力が働く。そして、外力が解除されると第１ケースと第２ケースが開いた状態で元の姿勢に戻ろうとするが、従来のような係合爪を開口穴に直接嵌入する構造では、係合リブの第１ケース内側に位置するエッジ部が、対応する開口穴の縁に引っかかり、元の状態に戻ることが困難であった。   In the case structure of this type of electronic device, when an external force is applied to the second case having the engagement rib, the engagement between the engagement claw and the opening hole is released, and the first member is housed in the first case. A force works in the opening direction between the case and the second case. Then, when the external force is released, the first case and the second case open and try to return to the original posture. However, in the conventional structure in which the engaging claw is directly fitted into the opening hole, It was difficult for the edge part located inside a 1st case to catch on the edge of a corresponding opening hole, and to return to an original state.

本発明は、係合リブを有する第２ケースに外力が加わることによって係合爪と開口穴との嵌合が外れたとしても、容易に元の状態に戻すことが可能な電子機器の筐体構造を提供することを目的とする。   The present invention provides a housing for an electronic device that can be easily returned to its original state even when the engagement between the engagement claw and the opening hole is released by applying an external force to the second case having the engagement rib. The purpose is to provide a structure.

本発明は、上記課題を解決するために、第１ケースには内側の側面から突出する係合爪を設け、第２ケースには側面から薄板状に延在して表面に前記係合爪を嵌入する開口穴を有した係合リブを設け、前記係合爪を前記開口穴に嵌入することによって前記第１ケースと前記第２ケースとを嵌合して内部に所定の部品を収納する電子機器の筐体構造において、前記開口穴に前記開口穴の深さよりも長いシート状の部材を挿入した後に前記開口穴に前記係合爪を嵌入することによって、前記係合リブの前記第１ケース内側に位置するエッジ部と対応する前記開口穴の縁との間に前記シート状の部材の一部が位置していることを特徴とする。   In order to solve the above-mentioned problems, the present invention provides the first case with an engaging claw protruding from the inner side surface, and the second case extends from the side surface in a thin plate shape and has the engaging claw on the surface. An electronic device that includes an engaging rib having an opening hole to be inserted and fits the first case and the second case by inserting the engaging claw into the opening hole to store a predetermined component therein. In the housing structure of the device, the first case of the engaging rib is formed by inserting the engaging claw into the opening hole after inserting a sheet-like member longer than the depth of the opening hole into the opening hole. A part of the sheet-like member is located between an edge portion located on the inner side and a corresponding edge of the opening hole.

さらに、前記シート状の部材は、樹脂シートであることを特徴とする。   Furthermore, the sheet-like member is a resin sheet.

さらに、前記シート状の部材は、前記開口穴に挿入した状態で両端を接着することによって前記開口穴に設置されていることを特徴とする。   Furthermore, the sheet-like member is installed in the opening hole by adhering both ends in a state of being inserted into the opening hole.

本発明によれば、開口穴に挿入され開口穴の縁に位置するシート状の部材が、係合リブの第１ケース内側に位置するエッジ部を開口穴に案内するので、係合リブを有する第２ケースに外力が加わることによって係合爪と開口穴との嵌合が外れたとしても、容易に元の状態に戻すことが可能な電子機器の筐体構造を提供することができる。   According to the present invention, the sheet-like member that is inserted into the opening hole and located at the edge of the opening hole guides the edge portion located inside the first case of the engagement rib to the opening hole, and thus has the engagement rib. Even when the engagement between the engaging claw and the opening hole is released by applying an external force to the second case, it is possible to provide a housing structure for an electronic device that can be easily returned to the original state.

なお、シート状の部材を樹脂シートとすれば、耐久性及び信頼性が向上する。   If the sheet-like member is a resin sheet, durability and reliability are improved.

また、シート状の部材を開口穴に挿入した状態で両端を貼り合わせることによって開口穴に設置するようにすれば、組み立て作業性が向上する。   Further, if the sheet-like member is inserted into the opening hole and the two ends are bonded together, the assembly workability is improved.

図１は、本発明の実施例であるデジタルカメラの外観斜視図である。図において、デジタルカメラのケース１は、第１ケース１ａと第２ケース１ｂを合わせて構成され、両ケース１ａ、１ｂは金属板をプレス加工して形成される。３１はレンズ鏡筒、３２は光学ビューファインダ、３３はストロボ、３４はシャッターボタンである。第１ケース１ａと第２ケース１ｂによって形成されるデジタルスチルカメラの内部には、回路基板、撮像素子、光学レンズ、バッテリー、記録媒体等の各種部材が収納されている。   FIG. 1 is an external perspective view of a digital camera that is an embodiment of the present invention. In the figure, a case 1 of a digital camera is configured by combining a first case 1a and a second case 1b, and both cases 1a and 1b are formed by pressing a metal plate. Reference numeral 31 denotes a lens barrel, 32 denotes an optical viewfinder, 33 denotes a strobe, and 34 denotes a shutter button. Various members such as a circuit board, an image sensor, an optical lens, a battery, and a recording medium are accommodated in the digital still camera formed by the first case 1a and the second case 1b.

図２（ａ）は第１ケース１ａと第２ケース１ｂを合わせる前の状態であって、図１の破線Ａで囲んだ部分を上から見た図であり、図２（ｂ）は図２（ａ）をＢ−Ｂ線を含む面にて破断した断面図である。第１ケース１ａには、内側の側面から突出する係合爪２を設けている。第２ケース１ｂには、側面から薄板状に延在して表面に係合爪２を嵌入する開口穴４と、組立て時に係合爪２を開口穴４に導く傾斜面５を有した係合リブ３を設け、開口穴４には係合爪２との係合力を増すための微小突起６が設けられている。そして、開口穴４にはシート状の部材である樹脂シート７が挿入されている。開口穴４に挿入された状態で樹脂シート７の両端は貼り合わされているので、樹脂シート７は開口穴４から外れない状態を保っている。よって、挿入しただけの場合に比べ組み立て作業性が向上する。なお、樹脂シート７の内側前面に接着剤を塗布し、開口穴４近辺の係合リブ３そのものに接着してもよい。   FIG. 2A shows a state before the first case 1a and the second case 1b are combined, and is a view of the portion surrounded by the broken line A in FIG. 1 as viewed from above, and FIG. It is sectional drawing which fractured | ruptured (a) in the surface containing a BB line. The first case 1a is provided with an engaging claw 2 protruding from the inner side surface. The second case 1b has an opening hole 4 that extends in a thin plate shape from the side surface and that engages the engagement claw 2 on the surface, and an inclined surface 5 that guides the engagement claw 2 to the opening hole 4 during assembly. The rib 3 is provided, and the opening 4 is provided with a minute projection 6 for increasing the engaging force with the engaging claw 2. A resin sheet 7 that is a sheet-like member is inserted into the opening hole 4. Since both ends of the resin sheet 7 are bonded together while being inserted into the opening hole 4, the resin sheet 7 is kept in a state where it does not come off from the opening hole 4. Therefore, the assembling workability is improved as compared with the case of only insertion. Alternatively, an adhesive may be applied to the inner front surface of the resin sheet 7 and bonded to the engagement rib 3 itself in the vicinity of the opening hole 4.

図３は係合爪２を開口穴４に挿入し第１ケース１ａと第２ケース１ｂが合わせられた状態を示す図である。図３（ａ）は図２（ａ）に、図３（ｂ）は図２（ｂ）に夫々対応する。図３は図２と共通する符号を付し、詳細な説明は割愛する。なお、図２（ｂ）、及び図３（ｂ）において、図示説明の都合上、樹脂シート７は太線で図示されているが、開口穴４の大きさに比べて十分薄いものである。また、開口穴４に設けられた微小突起６の図示は省略した。   FIG. 3 is a view showing a state in which the engaging case 2 is inserted into the opening hole 4 and the first case 1a and the second case 1b are combined. 3A corresponds to FIG. 2A, and FIG. 3B corresponds to FIG. 2B. 3 is denoted by the same reference numerals as those in FIG. 2, and detailed description thereof is omitted. In FIG. 2B and FIG. 3B, the resin sheet 7 is shown as a thick line for the convenience of illustration and explanation, but is sufficiently thinner than the size of the opening hole 4. Further, the illustration of the minute protrusion 6 provided in the opening hole 4 is omitted.

図４は、第２ケース１ｂに外力が加わることによって係合爪２と開口穴４との嵌合が外れた状態を示す断面図である。矢印Ｆで示す方向に第２ケース１ｂに外力が加わると、図のように係合爪２と開口穴４との嵌合が外れる。すると、内部に収納されている部材によって第１ケース１ａと第２ケース１ｂは開く方向に力が働くため、第１ケース１ａと第２ケース１ｂとの間には隙間Ｄが生じる。   FIG. 4 is a cross-sectional view showing a state in which the engagement between the engagement claw 2 and the opening hole 4 is released by applying an external force to the second case 1b. When an external force is applied to the second case 1b in the direction indicated by the arrow F, the engagement between the engagement claw 2 and the opening hole 4 is released as shown in the figure. Then, a force acts in the opening direction of the first case 1a and the second case 1b by the members housed therein, so that a gap D is generated between the first case 1a and the second case 1b.

そして、外力が解除される矢印Ｆとは逆方向の矢印Ｒの方向に第２ケースは元の状態に戻ろうとする。すると、第１ケース１ａと第２ケース１ｂとの間に生じた隙間Ｄの影響で、係合爪２の第１ケース１ａ内側に位置するエッジ部８が、対応する開口穴４の縁８と合致しない状態で係合爪２は開口穴４に入ろうとする。すると開口穴４の縁８の部分に位置する樹脂シート７が係合爪２のエッジ部８を滑らせて係合爪２を開口穴４へ案内することにより、係合爪２と開口穴４との嵌合が元に戻ることができる。さらに、係合爪２のエッジ部８及び対応する開口穴４の縁８を樹脂シート７が保護しているため、夫々の削れを防止している。開口穴４の縁８の部分に位置する樹脂シート７がなければ係合爪２の開口穴４への案内は行われず、元に戻ることができない。なお、図２（ｂ）、及び図３（ｂ）と同様に、図示説明の都合上、樹脂シート７は太線で図示されているが、開口穴４の大きさに比べて十分薄いものである。   Then, the second case tries to return to the original state in the direction of the arrow R opposite to the arrow F where the external force is released. Then, due to the influence of the gap D generated between the first case 1a and the second case 1b, the edge portion 8 located on the inner side of the first case 1a of the engaging claw 2 is in contact with the edge 8 of the corresponding opening hole 4. The engaging claw 2 tries to enter the opening hole 4 in a state where they do not match. Then, the resin sheet 7 positioned at the edge 8 of the opening hole 4 slides the edge portion 8 of the engagement claw 2 to guide the engagement claw 2 to the opening hole 4, whereby the engagement claw 2 and the opening hole 4. The fitting with can be restored. Furthermore, since the resin sheet 7 protects the edge portion 8 of the engaging claw 2 and the corresponding edge 8 of the opening hole 4, each scraping is prevented. Without the resin sheet 7 positioned at the edge 8 of the opening hole 4, the engagement claw 2 is not guided to the opening hole 4 and cannot be restored. 2B and 3B, for convenience of illustration, the resin sheet 7 is shown by a thick line, but is sufficiently thin compared to the size of the opening hole 4. .

以上、係合爪２を開口穴４に嵌入することによって第１ケース１ａと第２ケース１ｂを合わせることについて説明したが、、図１の破線Ａで囲んだ部分以外、特にデジタルカメラの底部にも第１ケース１ａと第２ケース１ｂを接合させる機構が施されている。該機構は、図１の破線Ａで囲んだ部分と同様であっても異なっていてもよい。   As described above, the first case 1a and the second case 1b are combined by fitting the engaging claw 2 into the opening hole 4. However, other than the portion surrounded by the broken line A in FIG. Also, a mechanism for joining the first case 1a and the second case 1b is provided. The mechanism may be the same as or different from the portion surrounded by the broken line A in FIG.

本実施例では、シート状の部材として樹脂シート７を用いた。樹脂であれば耐久性があり且つ表面の摩擦係数をちいさくすることができるので、係合爪２と開口穴４との嵌合が外れる、元の状態に戻す、という動作を繰り返したとしても、確実に係合爪２を開口穴４へ案内することことが可能となり、耐久性及び信頼性が確保される。しかしながら、シート状の部材の材質は、樹脂に限らず金属や炭素繊維でもよい。   In this example, the resin sheet 7 was used as a sheet-like member. Since it is durable if the resin is used and the friction coefficient of the surface can be reduced, even if the operation of releasing the fitting between the engaging claw 2 and the opening hole 4 and returning to the original state is repeated, It is possible to reliably guide the engaging claw 2 to the opening hole 4, and durability and reliability are ensured. However, the material of the sheet-like member is not limited to resin, but may be metal or carbon fiber.

上記実施例の説明は、本発明を説明するためのものであって、特許請求の範囲に記載の発明を限定し、或は範囲を減縮する様に解すべきではない。又、本発明の各部構成は、上記実施例に限らず、特許請求の範囲に記載の技術的範囲内で種々の変形が可能であることは勿論である。   The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. In addition, the configuration of each part of the present invention is not limited to the above-described embodiment, and various modifications can be made within the technical scope described in the claims.
