其等係在按壓部91之周圍，分別位於上下左右，該等之按 壓部91〜95被配置在互相接近之位置。而經由按壓周圍之 按壓部92〜95可以選擇各種設定項目，經由按壓中央之按 壓部9 1可以進入所選擇之項目。 其次，說明防水盒5 0。如第1圖所示，防水盒具有用來 收納數位靜像照相機70之盒本體1。盒本體1之構成包含 有：前盒2，覆蓋在數位靜像照相機70之前面部；後盒3， 覆蓋在數位靜像照相機70之後面部。前盒2和後盒3由透 明之合成樹脂構成，並在各自的一側部（在第1圖中爲右側 之側部）利用鉸鏈部4結合成可轉動。構建成以鉸鏈部4爲 中心使前盒2和後盒3轉動藉以進行開閉。 另外，在鉸鏈部4之相反側之側部（第1圖之左側之側 部）’鎖定構件5被設在前盒2和後盒3，利用該鎖定構件5 以閉合狀態鎖定前盒2和後盒3成爲可自由裝卸之構造。在 防水盒5 0，以前盒2覆蓋數位靜像照相機7 0之前面部，以 後盒3覆蓋數位靜像照相機7 G之後面部，將前盒2和後盒3 閉合，再利用鎖定構件5鎖定’藉此，以構成將數位靜像照 相機7 〇收納在盒本體1。在前盒2之前面，收納筒部6以突 1311229 出到前方之方式，與前盒2形成一體，在數位靜像照相機被 收納在盒本體1之狀態，將攝像透鏡部72插入到收納筒部6 內。另外’攝像透鏡部7 2成爲在收納筒部6內可以前後地 自由出沒。 如第1圖〜第2圖所示，在前盒2之上面設有與數位靜 像照相機70之快門鈕75對應之可按動之按鈕70,而在後盒 3之背面設有與再生鈕80對應之可按動的按鈕8、與變焦鈕 81之按壓部82對應之按鈕9、與按壓部83對應之按鈕10、 • 以及與功能鈕84對應之按鈕11。該等按鈕8〜10係沿著後 盒3之背面之上緣排列成一直線狀。 在後盒3之背面設有與功能鈕8 5對應之按鈕1 2、與功 能鈕86對應之按鈕13。而按鈕12和按鈕13位於按鈕8〜 1 1之下側。 另外，在後盒3之背面設有與十字形鈕90對應之按鈕 群20。按鈕群20位於按鈕7〜1 1之下側。其次，使用第3 圖〜第5圖來說明將按鈕群20安裝在後盒3之安裝構造51。 ^ 如第3圖所示，按鈕群20由與按壓部91〜95各自對應 的按鈕21〜25所構成。在此，按鈕21〜25當中的中央按鈕 2 1係位於中央，上按鈕22位於中央按鈕2 1之上側，下按鈕 23位於中央按鈕21之下側，左按鈕24位於中央按鈕21之 左側，右按鈕25位於中央按鈕21之右側。該等按鈕21〜25 被配置成互相接近。 如第4圖〜第5圖所示，按鈕2 1〜2 5分別具有：軸部 21a〜25a;頭部21b〜25b，被設在軸部21a〜25a之一方之 1311229 端部；彈接部21c〜25c，被設在軸部21 a〜25a之另外一方 之端部；和阻擋部21 d〜25d，被設在軸部21a〜25a成爲比 彈接部21c〜25c更靠近頭部21b〜25b。軸部21a〜25a之直 徑小於彈接部2 1 c〜2 5 c之直徑，彈接部2 1 c〜2 5 c之直徑小 於阻擋部2 1 d〜2 5 d之直徑，阻擋部2 1 d〜2 5 d之直徑小於頭 部21b〜25b之直徑。另外，彈接部21c〜25c係由橡膠等之 彈性材料所構成。 當對按鈕21〜25進行比較時，上下左右之周邊按鈕22 ® 〜25均成爲同樣之構造，但是中央按鈕21與按鈕22〜25 不同。實質上，針對中央按鈕21，頭部21b之頭頂面係被設 置成爲平坦，相對地，針對上下左右之按鈕22〜25，頭部 22b〜25b之頭頂面係被設置成凸曲面狀。另外，從頭部21b 之頭頂到頭部21b之下端之長度，係大於從頭部22b〜25b 之頭頂到頭部22b〜25b下端之長度，從頭部21b之頭頂到 彈接部2 1 c之下端之長度，係大於從頭部2 2 b〜2 5 b之頭頂 到彈接部2 2 c〜2 5 c之下端之長度。亦即，沿著軸方向之長 ® 度（從頭頂到下端之長度）是中央按鈕21比上下左右之按鈕 22〜25還長。 中央按鈕21被安裝成穿通後盒3之背面之方式而成爲 可以按動。實質上，中央按鈕21係依照以下之方式安裝β 在後盒3之背面且爲與數位靜像照相機7 0之按壓部9 1對應 之位置，設置凹陷之圓形形狀之凹部2 1 g，但是在後盒3之 內面之凹部21g之相反側設置成凸突。在凹部21g之底部， 安裝孔2 1 f係穿通到後盒3之內面側。另外，軸部2 1 a插入 -10- 1311229 到安裝孔2 1 f成爲可在軸方向滑動，中央按鈕2 1之頭部2 1 b 成爲在後盒3之外側（在第4圖，第5圖爲上側），彈接部2 1 c 和阻擋部2 1 d成爲在後盒3之內側。 另外，軸部2 1 a在後盒3之外側插入到線圈彈簧2 1 e， 線圈彈簧2 1 e捲繞在軸部2 1 a成爲具有餘隙。該線圈彈簧2 1 e 被設置在頭部2 1 b和凹部2 1 g的底部之間，用來使頭部2 1 b 朝向外側偏移。對於線圈彈簧2 1 e之偏移力，利用阻擋部2 1 d 與後盒3之內面接觸，用以抑制中央按鈕2 1朝向外側移動。 上下左右之按鈕22〜25被安裝成貫穿後盒3之背面， 而成爲可以按動。實質上，按鈕22〜25係依照以下之方式 安裝。在凹部21g之周圍，安裝孔22f〜2 5f形成穿通到後 盒3之內面側。在此，安裝孔22f〜25f係各自形成在與按 壓部92〜95對應之位置。 另外，軸部22a〜25a分別插入到安裝孔22f〜25f成爲 可以在軸方向滑動，頭部22b〜25b在後盒3之外側，彈接 部22c〜25c和阻擋部23d〜2 5d在後盒3之內側。軸部22a 〜25a在後盒3之外側分別插入到線圈彈簧22e〜25e，線圈 彈簧22e〜25e分別捲繞在軸部22a〜25a成爲具有餘隙。線 圈彈簧22e〜25e被設置在後盒3之背面和頭部22b〜25b之 間，用來使頭部22b〜25b分別朝向外側偏移。而相對於線 圈彈簧之偏移力，係利用阻擋部22d〜25d與後盒之內部接 觸，以抑制按鈕22〜25朝向外側移動。 在被安裝於後盒3之狀態’針對按鈕21〜25進行比較。 使以基準面（例如後盒3之背面或內面）作爲基準之彈接部 1311229 2lc朝向內側突出之高度，大於以同一基準面作爲基準之彈 接部22c〜25c朝向內側突出之高度。以同一基準面作爲基 準之彈接部2 2 c〜2 5 c朝向內側突出之高度均相同。在此處 以基準面作爲基準之彈接部21c〜25c朝向內側突出之高 度，成爲從基準面到彈接部2 1 c〜25 c之下端之距離。 因爲？早接部2 1 c朝向內側突出之局度，大於弾接部2 2 c 〜25c朝向內側突出之高度，所以從彈接部21c之下端到按 壓部91之距離，小於從彈接部22c〜25c之下端到按壓部92 ® 〜95之距離。因此，沿著軸方向之移動範圍，在左右之按鈕 22〜25大於中央按鈕21。 . 另外一方面，在後盒3之外側以同一基準面（例如後盒3 之背面或內面）作爲基準之頭部21b〜25b之朝向外側突出之 高度，成爲從基準面到頭部21b〜25b之頭頂之距離。 按鈕7〜13亦與中央按鈕或上下左右之按鈕22〜25同 樣地，被安裝在後盒3。 另外，在安裝孔21f〜25f內，於後盒3和軸部21a〜25a ® 之間設有密封材料，用來使後盒3和軸部21a〜25a之間之 間隙不會發生漏水。 在此種防水盒5 0，以鉸鏈4爲中心，使前盒2和後盒3 轉動藉以打開，將數位靜像照相機70配置在其內部，使前 盒2和後盒3閉合，在此種狀態利用鎖定構件5用來鎖定前 盒2和後盒3，藉以將數位靜像照相機7 0收納在盒本體1 內。利用此種方式可以使數位靜像照相機70防水。 在盒本體1內收納有數位靜像照相機70之狀態，當操 -12- 1311229 作數位靜像照相機7 0之情況時，按下按鈕7〜1 3，按鈕2 1 〜2 5 〇 經由按下按鈕7〜1 3，成爲按壓與其分別對應之快門鈕 7 5，再生鈕8 0 ’按壓部8 2以及按壓部8 3〜8 5。另外，當解 除按鈕7〜1 3之按下時，則回到原來之狀態，而解除快門鈕 75、再生鈕80、按壓部82以及按壓部83〜85之按壓。 另外一方面，當抵抗線圈彈簧2 1 e〜2 5 e之偏移力而按 下按鈕21〜25之頭部21b〜25b時，利用彈接部21c〜25c • 按壓分別對應之按壓部9 1〜9 5。當解除頭部2 1 b〜2 5 b之按 下時，利用線圈彈簧21e〜25e之偏移力使彈接部21c〜25c 離開按壓部91〜95，用來解除按壓部91〜95之按壓。 依照上述之方式，即使數位靜像照相機70被收納在防 水盒5 0之狀態，亦可以操作數位靜像照相機70。 在此，如第6圖所示，在只按下十字形鈕90中之按壓 部91時，以手指按下中央按鈕21之頭部21b，但是因爲按 鈕21〜25形成密集，所以手指會接觸在上下左右之按鈕22 ® 〜25之頭部22b〜25b，成爲亦按下頭部2 2b〜25b。在此種 情況，因爲從基準面到彈接部2 1 c之下端之距離，比從同一 基準面到彈接部22c〜25c之下端之距離短，所以按壓部91 被彈接部21c按壓，但是按壓部92〜95不會被按壓。因此， 在按壓部91〜95中只要按壓部91被按壓之情況，可以防止 其他之按壓部92〜95被按錯。 另外，因爲按鈕22〜25之頭部22b〜25b形成凸曲面 狀，所以在以手指壓入中央按鈕22〜25之頭部2 1 b時，因 1311229 爲手指不易接觸到頭部22b〜25b，所以可以防止錯誤地按下 按鈕22〜25。 另外，因爲中央按鈕22〜25之頭部21b之形狀與其他 按鈕2 2〜2 5之頭部2 2 b〜2 5 b之形狀不同’所以可利用摸索 以指定中央按鈕2 1。 另外，因爲頭部21b〜25b之頭頂全部一致’所以防水 盒50之背面側之形狀成爲整齊。 另外，使防水盒5 0之背面向下，設置防水盒5 0之情況 ® 時，因爲頭部2 1 b〜2 5 b之頭頂全部一致，所以不是按鈕2 1 〜25之任一個被按下，而是按鈕21〜25全部被按下。因此 負載分散到按鈕21〜25而可以防止按鈕21〜25意外地破 損。 第9圖所示之按鈕群安裝構造51A是使該按鈕群安裝構 造51之凹部21g之深度變淺者，中央按鈕22〜25之頭部21b 之頭頂比其他按鈕21〜25之頭部還高。亦即，中央按鈕21 之彈接部2 I C之朝向內側之突出高度，高於其他之按鈕2 1 ^ 〜25之彈接部22C〜25C朝向內側之突出高度。另外，對於 按鈕群安裝構造51A，在與按鈕群安裝構造51同樣之構成 元件附加同樣之符號，而其說明則加以省略。在此種情況， 亦可以獲得與上述所示者同樣之效果。 另外，本發明並不只限於上述之各個實施例，在不脫離 本發明之主旨之範圍內，可以進行各種之改良和設計之變 更。 在上述實施例中是做成1個突出高度比按鈕22〜25之 -14- 1311229 朝向內側之突出高度還高之按鈕2 1，但是亦可以將2個以上 的這種按鈕2 1設在後盒3。例如，將按鈕21以在左右排列 2個之方式，安裝在後盒3之背面，在2個之按鈕21之周圍 排列按鈕22〜25。在此種情況，在數位靜像照相機70，以 對應到2個之按鈕21和按鈕22〜25之方式，設置2個按壓 部91，在2個按壓部91之周圍排列按壓部92〜95。 另外，不只限於數位靜像照相機70，本發明亦可適用在 收納其他電子機器，例如視訊照相機，行動電話機，筆記型 個人電腦，手錶，PDA(Personal Digital Assistant)之防水 盒。在此種情況，盒本體之形狀配合電子機器之形狀。 【圖示簡單說明】 第1圖是防水盒5 0之斜視圖。 第2圖是防水盒5 0之背面圖。 第3圖是被設在防水盒50之背面之按鈕群20之平面圖。 第4圖是沿著第3圖所示之切斷線IV-IV之面之部份之 剖面圖。 第5圖是沿著第3圖所示之切斷線V-V之面之部份剖面 圖。 第6圖是用來說明按鈕群20之作用之圖面。 第7圖是從正面側所看到的數位靜像照相機70之斜視

The shaft portions 22a to 25a are inserted into the coil springs 22e to 25e on the outer sides of the rear case 3, and the coil springs 22e to 25e are wound around the shaft portions 22a to 25a, respectively, to have a clearance. The coil springs 22e to 25e are provided between the back surface of the rear case 3 and the head portions 22b to 25b for biasing the head portions 22b to 25b toward the outside. On the other hand, with respect to the biasing force of the coil spring, the blocking portions 22d to 25d are in contact with the inside of the rear case to suppress the movement of the buttons 22 to 25 toward the outside. The buttons 21 to 25 are compared in the state of being mounted in the rear case 3. The height of the elastic portion 1311229 2lc which is referenced to the reference surface (for example, the back surface or the inner surface of the rear case 3) toward the inner side is greater than the height at which the elastic portions 22c to 25c which are referenced to the same reference surface protrude inward. The heights of the elastic joints 2 2 c to 2 5 c protruding toward the inner side, which are the same reference plane, are the same. Here, the height of the elastic portions 21c to 25c which are guided toward the inner side with respect to the reference surface is the distance from the reference surface to the lower end of the elastic portion 2 1 c to 25 c. because? The degree of the early contact portion 2 1 c protruding toward the inner side is greater than the height at which the splicing portions 2 2 c 〜 25c protrude toward the inner side, so the distance from the lower end of the elastic joint portion 21c to the pressing portion 91 is smaller than that from the elastic joint portion 22c~ The distance from the lower end of 25c to the pressing portion 92 ® to 95. Therefore, the range of movement along the axis direction is larger than the center button 21 at the left and right buttons 22 to 25. On the other hand, the height of the heads 21b to 25b which are the same reference plane (for example, the back surface or the inner surface of the rear case 3) on the outer side of the rear case 3 protrudes outward from the reference surface to the head portion 21b. The distance from the top of 25b. The buttons 7 to 13 are also attached to the rear case 3 in the same manner as the center button or the up and down buttons 22 to 25. Further, in the mounting holes 21f to 25f, a sealing material is provided between the rear case 3 and the shaft portions 21a to 25a ® so that water leakage does not occur in the gap between the rear case 3 and the shaft portions 21a to 25a. In the waterproof case 50, centered on the hinge 4, the front case 2 and the rear case 3 are rotated to open, and the digital still camera 70 is disposed inside, and the front case 2 and the rear case 3 are closed. The state is used to lock the front case 2 and the rear case 3 by the locking member 5, whereby the digital still camera 70 is housed in the case body 1. In this way, the digital still camera 70 can be made waterproof. In the state in which the digital still camera 70 is housed in the cartridge body 1, when the -12-1311229 is used as the digital still camera 70, the buttons 7 to 1 3 are pressed, and the buttons 2 1 to 2 5 are pressed. The buttons 7 to 1 3 are pressed to respectively correspond to the shutter button 75, the reproduction button 80', the pressing portion 8 2, and the pressing portions 8 3 to 8 5 . Further, when the button 7 to 13 are released, the original state is returned, and the shutter button 75, the reproduction button 80, the pressing portion 82, and the pressing portions 83 to 85 are released. On the other hand, when the heads 21b to 25b of the buttons 21 to 25 are pressed against the biasing force of the coil springs 2 1 e to 2 5 e, the respective pressing portions 9 1 are pressed by the elastic portions 21c to 25c. ~9 5. When the pressing of the head portions 2 1 b to 2 5 b is released, the elastic portions 21c to 25c are separated from the pressing portions 91 to 95 by the biasing force of the coil springs 21e to 25e, and the pressing portions 91 to 95 are released. . According to the above, even if the digital still camera 70 is housed in the state of the water tank 50, the digital still camera 70 can be operated. Here, as shown in FIG. 6, when only the pressing portion 91 of the cross-shaped button 90 is pressed, the head 21b of the center button 21 is pressed with a finger, but since the buttons 21 to 25 are densely formed, the fingers are in contact. In the heads 22b to 25b of the up and down buttons 22 to 25, the heads 2 2b to 25b are also pressed. In this case, since the distance from the reference surface to the lower end of the elastic portion 2 1 c is shorter than the distance from the same reference surface to the lower end of the elastic portions 22c to 25c, the pressing portion 91 is pressed by the elastic portion 21c. However, the pressing portions 92 to 95 are not pressed. Therefore, in the case where the pressing portions 91 are pressed in the pressing portions 91 to 95, it is possible to prevent the other pressing portions 92 to 95 from being pressed. Further, since the heads 22b to 25b of the buttons 22 to 25 are formed in a convex curved shape, when the heads 2 1 b of the center buttons 22 to 25 are pressed by the fingers, the heads 22b to 25b are not easily contacted by the fingers 1311229. Therefore, it is possible to prevent the buttons 22 to 25 from being erroneously pressed. Further, since the shape of the head portion 21b of the center buttons 22 to 25 is different from the shape of the head portions 2 2 b to 2 5 b of the other buttons 2 2 to 25 5, the center button 21 can be designated by the groping. Further, since the heads of the heads 21b to 25b are all aligned, the shape of the back side of the waterproof case 50 is neat. In addition, when the back surface of the waterproof case 50 is downward and the case of the waterproof case 50 is set, since the heads of the heads 2 1 b to 2 5 b are all the same, none of the buttons 2 1 to 25 is pressed. Instead, buttons 21 to 25 are all pressed. Therefore, the load is dispersed to the buttons 21 to 25, and the buttons 21 to 25 can be prevented from being accidentally broken. The button group attachment structure 51A shown in Fig. 9 is such that the depth of the concave portion 21g of the button group attachment structure 51 is shallower, and the head top of the head portion 21b of the center buttons 22 to 25 is higher than the heads of the other buttons 21 to 25 . That is, the protruding height of the elastic portion 2 I C of the center button 21 toward the inner side is higher than the protruding height of the elastic portions 22C to 25C of the other buttons 2 1 ^ 25 to the inner side. In the button group mounting structure 51A, the same components as those of the button group mounting structure 51 are denoted by the same reference numerals, and the description thereof will be omitted. In this case as well, the same effects as those shown above can be obtained. Further, the present invention is not limited to the embodiments described above, and various modifications and changes can be made without departing from the spirit and scope of the invention. In the above embodiment, the button 2 is formed such that the protrusion height is higher than the protrusion height of the button 22 to 25 - 1411229 toward the inner side. However, two or more such buttons 2 1 may be provided later. Box 3. For example, the buttons 21 are attached to the back surface of the rear case 3 so as to be arranged on the left and right sides, and the buttons 22 to 25 are arranged around the two buttons 21. In this case, in the digital still camera 70, two pressing portions 91 are provided so as to correspond to the two buttons 21 and the buttons 22 to 25, and the pressing portions 92 to 95 are arranged around the two pressing portions 91. Further, the present invention is not limited to the digital still camera 70, and the present invention is also applicable to storage of other electronic devices such as video cameras, mobile phones, notebook personal computers, watches, and PDA (Personal Digital Assistant) waterproof boxes. In this case, the shape of the cartridge body matches the shape of the electronic machine. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of a waterproof case 50.
