8前端）形成中空圓柱狀握持 部2 8b。因此，使用者能握持握持部28b操作手把26。 此手把2 6是以設在內蓋1 0的軸3 0爲中心朝箭號D方 向（內蓋開放方向）轉動。然後，操作部28是藉由未圖示 的螺旋彈簧（coil spring )經常朝反箭號D方向轉動彈推 ，藉此在自由狀態下，形成第1圖所示的狀態。 -10- 1242618 ^ (6) 在前述手把2 6的基端構件2 7之下方部，藉由設在內蓋 1 0的軸3 2可轉動地軸支承有桿（1 e v e r ) 3 1，藉由未圖示 的彈簧經常朝箭號E方向轉動彈推。在此桿3 1形成有長溝 槽3 1a，形成在基端構件27的凸部27b可滑動地嵌合於此 長溝槽3 1 a。又，在此桿3 1形成長孔3 1 b，滾筒蓋鎖定解除 用的桿（drum lid unlocking rod) 33之凸部33a可滑動地 嵌合於此長孔3 1 b。又，在此桿3 1的下部（形成後述的鎖 定解除體（unlock member) 36側之部位），形成卡合凸 部 3 1 c 〇 此桿33是可朝反箭號F方向移動地插通於形成在蓋內 板12之插通同部34’此桿33的下端部之按壓部33b是與前 述鎖定解除承受部2 3相對向。在此桿3 3的凸部3 3 a附近部 ，形成突出片部33c，此突出片部33c是藉由與立設在蓋 內板12的導引件（guide ) 3 5滑接，來導引桿33之移動。 在桿3 1之前方，分別經由設在蓋內板〗2之軸3 8、3 9可 轉動地設有鎖定解除體3 6、鎖定體3 7，分別受到未圖示之 彈簧朝箭號G、箭號Η方向轉動彈推。 內蓋鎖定裝置13是藉由此鎖定體37及鎖定解除體36構 成。在鎖定解除體3 6，形成有能與前述桿3 I之卡合凸部 3 1 c卡合的被卡合凸部36a，並且形成制動部（stopper ) 36b’ 進一步形成有銷 ί女壓部（pin pushing portion) 36c 。在鎖定體37，形成鎖定溝槽（lock groove) 37a，在第1 圖的狀態下，與前述棘輪1 4卡合。且，在此鎖定體3 7，形 成被制動部（stopped portion ) 3 7b，在第]圖的狀態下， 1242618 ' (7) 此被制動部3 7 b卡合於前述鎖定解除體3 6之制動部3 6 b， 阻止該鎖定體3 7之箭號η方向之轉動。其結果，鎖定鎖 定體37與棘輪14之卡合，阻止內蓋1〇之開放（箭號a方 向），也就是鎖定的內蓋1 0之關閉。 且，在此鎖定體37，可移動地設置有銷（pin ) 40， 其是藉由未圖示之彈簧，時常朝箭號I方向移動彈推。在 此第1圖的狀態，處於受到鎖定解除體3 6的銷按壓部3 6 c 朝反箭號I方向所移動之狀態。 又，在水槽8，於棘輪1 4的附近部位，設置作爲內蓋 關閉檢測手段之例如微動開關（micro switch ) 41，在此 微動開關41的引動器（actuator ) 41a，可移動地設置有中 間銷（intermediate pin ) 42，使其一端與之相對向。此底 部42是受到未圖示的彈簧經常朝箭號J方向移動彈推，在 此第1圖的狀態下，藉由銷40朝反箭號J方向移動，使微 動開關4 1處於導通（ON )狀態，即處於檢測到內蓋1 〇關 閉之狀態。 一方面，在前述桿3 3的後方部，設有自動關閉手段之 滾筒蓋自動關閉裝置（drum lid automatic closing device )43。說明關於此滾筒蓋自動關閉裝置43。關閉滾筒蓋1 6 的關閉構件之複數個例如左右兩個按壓構件44，設置成藉 由導引部（guide portion ) 45可朝箭號K方向移動。在此 按壓構件44的下端部形成按壓部44a，在上端部形成彈簧 承受部Ob。前述按壓部44a是對向於對應於前述蓋主板 16a之被鎖定板20的前端部分16c。然後，此按壓構件44 1242618 ^ (8) 是藉由彈簧4 6經常朝反箭號K方向移動彈推，在關閉了 內蓋1 〇之狀態下，位於第1圖的位置。 在此按壓構件4 4，連結有連桿（1 i n k ) 4 7。此連桿4 7 是具有第1桿48、與較第1桿短之第2桿4 9來構成，第1桿48 的一端部是經由軸5 0可轉動地連結於前述按壓構件44之上 部，另一端部是經由軸5 3可轉動地連結於緩衝裝置5 1之外 殼（c a s e ) 5 2。第2桿4 9的一端部是經由軸5 4可轉動地連 結於蓋內板1 2，另一端部是經由軸5 5連結於第1桿4 8的軸 間距離之W2長度的位置。即，對於第1桿4 8的軸間距離， 第2桿49之軸間距離爲1/2。根據如此的連桿47之結構，當 第1桿48之另一端部朝箭號L方向（反箭號L方向爲後述 的馬達5 9之驅動力的作用方向）移動時，則第1桿4 8之一 端部是朝與該箭號L方向呈垂直的箭號K方向移動者。 前述緩衝裝置51是具備呈矩形箱狀之前述外殼52、桿 56、及由壓縮螺旋彈簧所構成的彈簧57來構成。在傳動機 構5 6的一端部，形成彈簧承受部5 6a，進一步在此彈簧承 受部56a的一部分，形成朝外殼52外突出之引動器作動部 (actuator operating portion ) 56b (參照第 6圖）° 又此 桿56的另一端部56c是由外殼52突出。前述彈簧57是在壓 縮狀態下設置於前述彈簧承受部56a與外殻52的內面之間 〇 在此緩衝裝置51，當桿56的另一端部56c朝箭號L方 向被拉引時，則通常，如第1 1圖所示，該緩衝裝置51整個 移動使連桿47作動，但在例如連桿47側受到某種理由所鎖 -13- 1242618 (9) 定的情況時，如第1 2圖所示，桿5 6對於外殻5 2相對地抵抗 彈簧5 7的彈力，而朝箭號L方向移動。 在前述桿5 6的另一端部5 6 c，連結有金屬線（w i r e ) 5 8，此金屬線5 8的另一端部是連結於如第6圖所示的驅動 源之例如馬達5 9的未圖示之輸出部。此馬達5 9是配設於內 蓋10之轉動軸12a附近部位。又，此馬達59是由齒輪馬達 (geared motor )所構成者，輸出部是以低速·高轉矩（ h i g h t 〇 r q u e )旋轉。然後，此馬達5 9的電力供給用導線 5 9 a是如第7圖所示，由內蓋1 0的導線導出部（1 e a d' w i r e lead -out portion) 10a導出。即，電力供給用導線59a是 由轉動軸1 2a部分導出至外部。此馬達59是當通點時則旋 轉，根據該旋轉捲繞前述金屬線5 8。 在前述內蓋1 〇之金屬線5 8的途中部，藉由托架（ bracket) 61安裝經路變換用滑輪（pulley) 60，前述金屬 線5 8是經由此滑輪6 0的上部。在前述托架6 1，於上端部， 形成由用來防止由前述金屬線58的滑輪60脫離之水平狀片 部所構成的制動部6 1 a。 又，在前述緩衝裝置5 1之箭號L方向側的部分，設有 用來檢測關閉構件之按壓構件44的關閉動作的滾筒蓋用關 閉檢測手段之微動開關62 (參照第6圖），這是其引動器 62a在箭號L方向與前述緩衝裝置51之引動器作動部56b 相對向。當前述緩衝裝置5 1受到馬達59所移動至如第1 ]圖 所示的位置時，即按壓構件44關閉滾筒蓋16時，藉由引動 器作動部5 6b導通（ON )微動開關62，藉此檢測按壓構件 1242618 (10) 44之關閉動作，以此檢測來檢測滾筒蓋1 6之關閉。根據此 微動開關62導通，將前述馬達59斷電，當馬達59被斷電時 ，則由於解除對於朝按壓構件44之連桿47的按壓力，故按 壓構件44可藉由彈簧46返回到原來的狀態（參照第1圖） 〇 在第7圖，在內蓋10的蓋外板11，形成工具插通孔63 ，在此工具插通孔6 3的內側，如第1 3及1 4圖所示，設有解 除桿（unlock lever ) 64，在此解除桿64的一端部下面， 形成在前端具有彈性爪部64a之插入軸部64b，其是可轉 動地插通於形成在蓋內板1 2之轂部（b 〇 s s ) 6 5，藉由彈性 爪部64a來防止脫落。解除桿64是另一端部64c可朝箭號 Μ方向轉動。且，在此解除桿6 4的一端部的轉動中心上面 ，形成支柱部64d，在其上端形成螺旋旋轉用溝槽64e。此 解除桿64的上端部是可轉動地嵌合於前述工具插通孔63， 螺旋旋轉用溝槽6 4 e是由此工具插通孔6 3面臨於外部。 前述解除桿64之另一端部64c是經由解除用金屬線66 連結於前述內蓋鎖定裝置13的鎖定解除體36之下部。再者 ，解除用金屬線66是藉由方向變換構件67a、67b:適宜地 變換方向。 如第1 3圖所示，當由內蓋1 〇外部藉由例如螺絲起子（ driver ) 68將解除桿64朝箭號Μ方向轉動操作時，則鎖定 解除體3 6朝反箭號G方向轉動，形成鎖定體3 7可對於棘 輪14解除卡合。 再者，前述滾筒蓋]6在旋轉停止時，其開口部15c與 -15- 1242618 (11) 前述水槽8的開口部8 a —致地加以定位。 其次說明關於前述結構的作用。在第1圖，顯示關閉 滾筒蓋1 6，且受到滾筒蓋鎖定手段1 9所鎖定，內蓋1 〇被內 蓋鎖定裝置1 3鎖定著之狀態。 在由此狀態打開內蓋1 0時的情況時，使用者握持手把 2 6的握持部2 8 b之全周外面朝箭號D方向轉動操作。於是 ’藉由凸部27b朝箭號D’方向轉動使得桿31朝反箭號E方 向轉動，而桿3 3朝反箭號F方向移動。藉此，鎖定解除承 受部23被按壓，輔助板16b的鎖定片21由被鎖定孔22脫離 ，解除滾筒蓋1 6的關閉狀態之鎖定。在解除後，滾筒蓋i 6 的蓋主板1 6a藉由未圖示的彈簧朝箭號B方向轉動，.抵接 於內蓋1 〇的內面（參照第8圖）。 又，藉由桿31朝反箭號E方向的轉動，使鎖定解除體 3 6朝反箭號G方向轉動，制動部3 6b由鎖定體3 7的被制動 部3 7b脫離，容許鎖定體37朝箭號Η方向的轉動（參照第 8圖）。在此狀態，內蓋1 0尙未進行開放動作。 當由此第8圖的狀態，如第9圖所示地打開內蓋1 〇時， 則被朝箭號Η方向轉動彈推之鎖定體3 7 —邊朝該方向旋 轉一邊由棘輪1 4脫離。然後，進一步打開內蓋〗〇則形成第 4圖的狀態。 在由此第4圖的狀態關閉內蓋1 0的情狀時，將內蓋1 〇 朝箭號A ’方向（箭號Α方向）關閉操作。當經過關閉途 中的第9圖之狀態，進一步進行關閉操作時，則鎖定體3 7 的鎖定溝槽37a之上邊部37c與棘輪14遭遇後朝反箭號Η 1242618 (12) 方向轉動，如第1 〇圖所示，鎖定體3 7的鎖定溝槽3 7 a對於 棘輪14加以嵌合。此時，藉由鎖定體37的被制動部37b通 過鎖定解除體3 6的制動部3 6b，使得鎖定解除體3 6朝箭號 G方向轉動，鎖定解除體36的制動部36b與被制動部37b 卡合。其結果，內蓋1 0的關閉被鎖定。此時，銷4 0受到鎖 定解除體36的銷按壓部36c所朝反箭號I方向按壓移動， 而將中間銷42朝反箭號J方向推壓。藉此，微動開關4 1被 導通（ON )，檢測內蓋1 〇之關閉。 藉由此微動開關4 1導通（ON )，通電驅動馬達5 9，· 經由金屬線5 8及緩衝裝置5 1，將連桿4 7的第1桿4 8朝箭號 L方向拉引。藉此，第1桿4 8的一端部朝與箭號L方向呈 垂直的方向動作。藉此，按壓構件4 4朝箭號K方向移動 (參照第1 1圖）。 藉由此按壓構件4 4之移動，滾筒蓋1 6的蓋主板1 6 a按 壓於輔助板1 6b。此時，蓋主板1 6 a的最前端部1 6 d形成暫 時乘載於輔助板16b的鎖定解除承受部23之狀態，進一步 按壓，則最前端部1 6 d落下到鎖定解除承受部2 3下側，此 時輔助板1 6 b的鎖定片2 1卡合於被鎖定孔2 2。 當已朝箭號L方向移動之前述緩衝裝置5 ；[的引動器作 動部56b按壓微動開關62的引動器62a時，導通而檢測按 壓構件4 4之關閉動作，根據此檢測，來檢測滾筒蓋I 6之關 閉。根據此檢測將馬達5 9斷電，形成如第1圖所示的狀態 〇 若根據如此的本實施例的話，具有輸出關閉滾筒蓋j 6 -17- 1242618 (13) 的驅動力之馬達5 9，設置根據此馬達5 9的動作自動關閉前 述滾筒蓋1 6之滾筒蓋自動關閉裝置4 3 °藉此’不須麻煩使 用者的手而可自動地進行滾筒蓋1 6之關閉’提昇實用性， 並且能確實地關閉滾筒蓋1 6。 又，若根據本實施例的話，由於在內蓋1〇設置馬達59 ，故容易進行導線5 9 a的配線。 特別是由於將馬達59設置於內蓋10的轉動軸12a附近 ，故能夠縮小打開內蓋1 0所需之操作力。 又，在滾筒蓋自動關閉裝置43，由於藉由連桿47將馬 達5 9的驅動力之作用方向變換成大致垂直後傳達至按壓構 件44，故能夠以小的空間（space )變換動力傳達方向， 因此能有助於內蓋1 0之薄型化。 且，由於設置金屬線5 8作爲由馬達5 9對於連桿4 7之動 力傳達構件，故在馬達59的配置位置設定上具有自由度。 又’若根據本實施例的話，由於設置檢測滾筒蓋自動 關閉裝置4 3的關閉動作之微動開關6 2，故能夠藉由此微動 開關62 ’根據關閉動作檢測，來將該滾筒蓋自動關閉裝置 43的馬達59斷電。 又’由於當藉由此微動開關62檢測到關閉動作時，停 止馬達5 9的動作（斷電），故能夠自動結束關閉動作。 且’若根據本發明的話，在滾筒蓋自動關閉裝置43， 由於經由緩衝裝置5 1連結按壓構件4 4與馬達5 9，故即使在 按壓構件4 4或連桿4 7鎖定在不能動作之狀態的情況時，也 肯匕夠谷s午馬達5 9動作，而可防止該馬達5 9的鎖定，並且能 1242618 * (14) 夠防止按壓構件44或連桿47、進一步金屬線58等之破損。 又，若根據本實施例的話，由於馬達59的導線59a由 內蓋1 〇之轉動軸1 2 a部分導出至外部’故極爲容易進彳了配 線，並且能夠縮小配線空間。 且，若根據本實施例的話，由於設有：設置於水槽8 側之棘輪Μ ;設置於內蓋1 〇，而當此內蓋1 0關閉時，與該 棘輪14卡合來鎖定內蓋10之關閉的內蓋鎖定裝置13 ;及以 此內蓋鎖定裝置1 3的鎖定動作檢測內蓋1 0的關閉之微動開 關4 1，故能夠確實地檢測內蓋1 0之關閉。在此情況時，由 於使微動開關4 1作動的構件之內蓋鎖定裝置1 3是位於內蓋 10側，而微動開關41位於水槽8側，故能夠確實地檢測內 蓋1 〇之關閉。即，當微動開關4 1也存在於內蓋鎖定裝置1 3 所存在的內蓋1 〇側時，會有使用者在內蓋1 0打開狀態下不 小心誤觸微動開關4 1或不小心誤觸滾筒蓋自動關閉裝置4 3 時，錯誤地進行內蓋1 0之關閉檢測的情事產生，但在本實 施例不會有如此之情事產生。 又，若根據本實施例的話，將根據微動開關4 1之內蓋 1〇關閉檢測結果利用在馬達59的驅動開始（通電），故能 夠在內蓋1 〇的確實關閉狀態下進行滾筒蓋1 6之關閉動作。 又，若根據本實施例的話，由於設置解除桿6 4，能夠 由內蓋1 〇外部操作之，且連結著此解除桿6 4與內蓋鎖定裝 置1 3之鎖疋解除體3 6 ’故即使手把2 6破損或形成不能動作 的情況時，也能夠藉由轉動操作此解除桿64，解除內蓋鎖 定裝置1 3之鎖定。 1242618 (15) 即，處於關閉狀態的內蓋〗〇，通常是藉由手把26的開 放操作使鎖疋解除體3 6動作，解除內蓋1 〇之鎖定，但當滾 筒蓋1 6受到異常而無法打開時，由於桿3 3無法充分移動， - 故桿31不能充分動作，鎖定解除體36無法解除鎖定體37之 鎖定。即使在此情況時，也能夠藉由操作前述解除桿6 4容 易將內蓋10鎖定解除。 且’若根據本實施例的話，由於在內蓋丨〇設置手把2 6 ，根據此手把2 6 ·手動操作，進行滾筒蓋】6之開放，故能 馨 夠以不具有馬達等的驅動源之結構進行內蓋1 〇之開放。 在此情況時，由於手把26具有握持部28b，故使用者

In particular, since the motor 59 is provided near the rotation shaft 12a of the inner cover 10, the operating force required to open the inner cover 10 can be reduced. Further, in the roller cover automatic closing device 43, the action direction of the driving force of the motor 59 is converted to be substantially vertical by the link 47 and transmitted to the pressing member 44, so that the power transmission direction can be changed in a small space. Therefore, the thickness of the inner cover 10 can be reduced. In addition, since the metal wire 5 8 is provided as a power transmission member for the connecting rod 4 7 by the motor 59, there is a degree of freedom in setting the position of the motor 59. In addition, according to this embodiment, since the micro switch 62 is installed to detect the closing action of the roller cover automatic closing device 4 3, the micro switch 62 can be used to automatically close the roller cover according to the closing operation detection. The motor 59 of 43 is powered off. Furthermore, when the closing operation is detected by the micro-switch 62, the operation of the motor 59 is stopped (power off), so the closing operation can be automatically ended. In addition, according to the present invention, the roller cover automatic closing device 43 is connected to the pressing member 4 4 and the motor 59 via the buffer device 51, so that even if the pressing member 4 4 or the connecting rod 4 7 is locked in an inoperative state In the case of the motor, it is also willing to act on the motor 5 9 to prevent the motor 5 9 from being locked, and to prevent the damage of the pressing member 44 or the connecting rod 47 and the further metal wire 58. . Furthermore, according to this embodiment, since the lead wire 59a of the motor 59 is led out from the rotating shaft 12a of the inner cover 10 to the outside ', the wiring is extremely easy to enter, and the wiring space can be reduced. Moreover, according to this embodiment, since: a ratchet M provided on the side of the water tank 8 is provided; and the inner cover 10 is provided, and when the inner cover 10 is closed, it is engaged with the ratchet 14 to lock the inner cover 10 The closed inner cover locking device 13 and the micro switch 41 for detecting the closing of the inner cover 10 by the locking action of the inner cover locking device 13 can detect the closing of the inner cover 10 reliably. In this case, since the inner cover locking device 13 which is a member that activates the micro switch 41 is located on the inner cover 10 side, and the micro switch 41 is located on the water tank 8, the closing of the inner cover 10 can be reliably detected. That is, when the micro switch 41 is also present on the inner cover 10 side where the inner cover locking device 1 3 is present, there is a user who accidentally touches the micro switch 41 by mistake or accidentally when the inner cover 10 is opened. When the roller cover automatic closing device 4 3 is touched, a situation in which the closing of the inner cover 10 is erroneously detected may occur, but this situation does not occur in this embodiment. In addition, according to this embodiment, the inner lid 10 is closed based on the detection result of the micro switch 41, and the driving of the motor 59 is started (power is applied), so that the drum lid 1 can be carried out with the inner lid 10 securely closed. 6's closing action. In addition, according to this embodiment, since the release lever 64 is provided, the inner cover 10 can be operated externally, and the lock release body 3 6 ′ that connects the release lever 64 and the inner cover locking device 13 is connected. Even when the handlebar 2 6 is damaged or becomes inoperable, the release lever 64 can be operated by turning to unlock the inner cover lock device 13. 1242618 (15) That is, the inner cover in the closed state is usually operated by the opening operation of the handle 26, and the lock release body 36 is moved to unlock the inner cover 10. However, when the roller cover 16 is abnormal, If it cannot be opened, the lever 33 cannot move sufficiently,-the lever 31 cannot operate sufficiently, and the lock release body 36 cannot release the lock of the lock body 37. Even in this case, the inner cover 10 can be easily unlocked by operating the aforementioned release lever 64. And 'If according to this embodiment, since the handle 2 6 is provided in the inner cover, according to this handle 2 6 · Manual operation, the roller cover is opened], so it can be driven without a motor or the like The structure of the source is opened by the inner lid 10. In this case, since the handlebar 26 has a grip portion 28b, the user can hold the handlebar 26 firmly for operation, and can reliably open and operate the inner cover 10. That is, when the handle is only flat, the finger is placed on the handle to open the handle. However, if the finger becomes wet or detergent is attached, the finger may slide from the handle. However, according to this embodiment, the entire circumference of the holding portion 2 8 b can be firmly held, and the lack of finger sliding can be eliminated. φ In addition, since the handle 26 connects the base end member 27 and the operation portion 28 by the engaging means 29, the base end member 27 can be assembled to the inner cover 10 first, and then the operation portion 28 can be connected to the base end. The component 27 makes the assemblability of the handle 26 good. Fig. 15 is a diagram showing a second embodiment of the present invention. In this embodiment, a sag prevention device 71 corresponding to the sag prevention means for preventing the metal wire 58 from sagging is provided. This sag prevention device 71 is formed with a long hole 72a in the bracket 72. Here, the long hole 72a rotatably arranges the shaft 73a of the pulley 73 for changing the path of the wire 58, and the shaft 73a is directed toward the arrow by a spring 74 No. N moves and pushes. -20 · 1242618 (16) Thereby, the metal wire 58 can be prevented from sagging, the metal wire 58 can be prevented from falling off by the pulley 73, and the length of the metal wire 58 can be set with ample space. The present invention is not limited to the above embodiments, and the present invention can be modified as described below. That is, it is also possible to use an air cylinder or a hydraulic cylinder as a driving source. It is also possible to use a light sensor or a limit switch as a means for detecting the closing of the roller cover and a means for detecting the closing of the inner cover. In addition, the shape of the cross section of the Lu grip portion of the handlebar need not be circular, but may be semicircular or oval.
