【考务明户斤屬身支4軒々頁J 發明領域 本發明係有關一種行動終端裝置，其具有：電池蓋， 係閉塞住收容電池之電池室者；鎖定機構，係將該電池蓋 鎖定於裝置本體者。 I[身ό前标]1 發明背景 近年來，尤其是業務用之行動終端裝置，在使用例如 掃描裝置等時消耗之電力量增加，必須定期交換充電電池 (例如1次/天），於是電池蓋被設計為可用簡單地操作來進行妒 卸之構造。 而且，也希望電池蓋能滿足在例如掉落時即使遭受到 衝擊亦不會破損，且能維持防水功能的規格。 另外’包含行動終端裝置在内之電子機器之防水規 格’例如、JIS/IEC(國際電子標準會議）中所謂ΙΡΧ7保護等級 的防水水準，係設定為在溫度範圍15〜35t等下，裝置最下 端潛至水面lm之下，經過3〇分鐘的測試時間仍不會進水的 程度6 因此’行動終端裝置最好係在不小心掉落裝置時難以 毁損，且具有不會輕易損及防水功能之耐衝擊性，更者在 蓋子閉塞時可得到防水所需之墊圈壓力。 對此，例如專利文獻1 _揭示有一種構造，係在電磁波 遮蔽盒中，操作複數個把手來旋轉各旋轉板，藉此使各個 201138596 卡合片與突起卡合，而蓋體會被鎖定在盒本體中左右寬度 方向的前後共四個位置上。 而且，專利文獻2揭示有一種構造，係在行動電子機器 之電池蓋中，將電源開關作為三個位置的滑動開關，並使 具有兩處突起之操作旋鈕嵌合於電池蓋凹部之三個位置中 的兩個位置，再以這兩個位置鎖定電池蓋的滑動。 更且，專利文獻3揭示有一種構造，係在箱型框體中， 將安裝於蓋子上之臂板以長方向中間之螺絲為中心加以旋 轉，則設置於兩端之嵌合部會分別上下相反方向地嵌合於 形成在框體上的嵌合穴，以將蓋子鎖定在框體的兩處上。 然而在專利文獻1中雖具有以鉸鏈部與盒本體樞接來 閉塞住收容部的蓋體，但是盒本體與蓋體係在左右兩側四 處卡合加以鎖定之構造，故機構較為複雜，零件數量也較 多。而且當不小心掉落盒本體時，鉸鏈部有受衝擊而變形 或毁損之虞。而且當鉸鏈部毀損，則有損及收容部防水功 能之虞。 而且專利文獻2中，操作旋鈕之兩處突起係直接嵌合於 電池蓋的凹部，故不小心掉落行動電子機器時，掉落之衝 擊會直接作用於操作旋鈕與電池蓋的嵌合部上，嵌合部則 有毀損或·脫落之虞。此時，將損及電池室的防水功能。 而且專利文獻3中，雖然採用受到衝擊也不會使鎖定 (嵌合）鬆脫的構造，但完全沒考慮框體内部之防水性。因此 該構造中，容易從框體與蓋的隙縫之間進水。 先前技術文件 201138596 專利文件 專矛！文件1.曰本特開平8_316678號公報 專利文件2 .日本特開平9_32657〇號公報 專利文件3 .日本特開20〇2· 111244號公報 C ;务明内容】 發明揭示 本發明係提供—種行祕端裝置，其可以簡單地構、生 藉由操作操作設備使電池蓋鎖定在複數個 力且可保持时性。 具耐衝擊 本發明係一種行動終端裝置，係具有： 電池蓋m於裝置本體且閉塞住收容電池之電池 鎖定機構，係將該電池蓋鎖定於前述裝置本體， 且其特徵在於，前述鎖定機構具有：桿構件，係係。 移動設置於前述電池蓋者；操作設備，係操作該桿構件者可 及卡合構件，係設置於前述裝置本體，且前述桿構件隨著 前述操作設備之操作而移動時，使該桿構件之兩端部:合 前述電池蓋，係藉由前述桿構件與前述卡合構件卡 合，以源自於該卡合構件之反作用力，而推壓至前述裝置 本體側者。 若依本實施形態，在閉塞電池室時，電池蓋會以源自 於卡合構件之反作用力而被推壓至裝置本體側，故電池室 會無隙縫地被閉塞住，而可維持防水性。 5 201138596 圖式簡單說明 第1圖係從前面側看本發明實施形態之行動終端裝置 的外觀圖。 第2圖係從背面側看同上裝置的外觀圖。 第3圖係取下電池蓋從背面側看行動終端裝置的外觀 圖。 第4圖係從内面側看電池蓋時的外觀圖。 第5圖係從内面側看外側蓋時的外觀圖。 第6圖係將内側蓋積層於外側蓋内面時之電池蓋的分 解立體圖。 第7圖係桿臂、操作板、及操作旋鈕的分解立體圖。 第8圖係同上之組裝圖。 第9圖係從内面側看電池蓋時的平面圖。 第10A圖係表示桿臂解除鎖定狀態的圖。 第10B圖係表示桿臂呈鎖定狀態的圖。 【實施方式3 用以實施發明之形態 以下依據圖式說明本發明之實施形態。 第1圖係從前面側看本發明實施形態之行動終端裝置 的外觀圖；第2圖係從其背面側看的外觀圖。 行動終端裝置，例如已知的HHT(Hand Held Terminal) ’係可攜帶且可進行銷售管理、庫存管理、或進 貨管理、其他、無線通訊等功能的小型行動機器。 第1圖中，該行動終端裝置10係在俯視呈細長矩形的裝 201138596 置本體12前面，具有輸出選單畫面或已記錄之資料的液晶 顯不器（LCD)等顯示部14、作為操作輪入資料之資料輸入部 的輪入鍵16、以及選擇按叙18等，且裝置本體12内部，具 有將輸入鍵16所輸入之資料等加以處理之未圖示的資料處 理部（運算部）等。 另外’本實施形態之行動終端裝置雖無配備，但也有 配備具列印功能之印表機的規格。 第2圖中，行動終端裝置1〇的背面側，具有將收容電池 20之電池室26之開口部26a(參考第3圖）加以閉塞的電池蓋22。 此電池蓋22之後會詳細敘述’可由操作旋鈕62之旋轉 操作來鎖定或開鎖，而對開口部26a進行裝卸。 此行動終端裝置10 ’係裝載有可讀取物品（商品）上所附 加之條碼資訊的未圖示之掃描器單元(標示讀取單元）。 另外，使用此行動終端裝置發送電子郵件等時，當使 用者使用輸入鍵16輸入電話號碼或電子郵件位址，則會藉 由遠距離用無線通訊，將資料發送給指定的通訊對象。已 發送的資料會從基地台透過電話線路、LAN線路等，傳送 到通信對象處。 第3圖係取下電池蓋2 2從背面側看行動終端裝置1 〇時 的外觀圖。 本實施形態中，電池20係充電電池，，可自由裝卸地 收容於形成在裝置本體12之背面側的電池室26中。此電池 室2 6，係藉由以電池蓋2 2覆蓋開口部2 6 a，而維持防水功能。 開口部26a，係開口在裝置本體12之長方向（第3圖中γ 201138596 方向）之下方側大約一半處❶而且，裝置本體12之長方向大 略中央處，且在開口部26a的上方側，形成有鎖定機構收容 部28。 此鎖定機構收容部28，在裝置本體12背面與收容部本 身的邊界上形成有高低差。此高低差相當於覆蓋鎖定機構 收容部28之電池蓋22的厚度部分。如此一來，若將電池蓋 22裝配於電池室26之開口部26a’則裝置本體12的背面便成 為平滑表面（參考第2圖）。 而且，鎖定機構收容部28在裝置本體12之寬度方向（第 3圖中X方向）的大略中央處，具有操作旋鈕收容部32。而且 此鎖定機構收容部28之寬度方向的左右兩端側，設置有作 為咬卡合構件之朝向裝置本體12長方向（.第3圖中γ方向）下 方的卡合銷34、35。此卡合銷34、35會與後述之鎖定機構 60的桿背61卡合。 而且，在電池室26之開口部26a下方（第3圖中γ方向下 方）的左右端部切削出爪安裝部36、37。電池蓋22之爪4〇、 41 (參考第4圖）係勾掛固定於此爪安裝部36、37。 而且，電池至26之開口部26a周圍，係形成有較薄之壁 面30。後述之墊圈48(參考第4圖等）抵接於此壁面3〇,以維 柏:電池室26之防水功能。 第4圖係從内面側看電池蓋22時的外觀圖。 此電池蓋22，係具有將外側蓋22A和内側蓋22B加以積 層的一體構造。 此電池蓋22可閉塞住電池室26之開口部26a，並對衝擊 8 ⑧ 201138596 力等具有特定強度，且具有達到優秀防水規格標準之防水 功能（例如JIS/IEC中的IPX7等級）。 第5圖，係從内面側看外側蓋22A時的外觀圖。 如第5圖所示，外側蓋22 A係由合成樹脂等（例如聚碳酸[The invention relates to a mobile terminal device having a battery cover that closes a battery compartment for housing a battery; and a locking mechanism that locks the battery cover On the device body. BACKGROUND OF THE INVENTION In recent years, in particular, mobile terminal devices for business use increase the amount of power consumed when, for example, a scanning device is used, and it is necessary to periodically exchange rechargeable batteries (for example, once per day), and thus the battery The cover is designed to be easily handled for handling. Further, it is also desired that the battery cover can satisfy the specifications that it can be broken even if it is subjected to an impact even when it is dropped, and the waterproof function can be maintained. In addition, the waterproof standard of the electronic device including the mobile terminal device, for example, the waterproof level of the ΙΡΧ7 protection level in the JIS/IEC (International Electronic Standards Conference) is set to the lower end of the device in the temperature range of 15 to 35t. Dive below the surface of the water lm, after 3 minutes of testing time, it will not enter the water level. 6 Therefore, the mobile terminal device is preferably difficult to damage when the device is accidentally dropped, and has a function of not easily damaging the waterproof function. Impact resistance, even when the cover is closed, the gasket pressure required for waterproofing. In this regard, for example, Patent Document 1 discloses a configuration in which an electromagnetic wave shielding box is operated to operate a plurality of handles to rotate the respective rotating plates, whereby the respective 201138596 engaging pieces are engaged with the projections, and the cover is locked in the case. There are four positions in the front and rear of the body in the left and right width direction. Further, Patent Document 2 discloses a configuration in which a power switch is used as a slide switch of three positions in a battery cover of a mobile electronic device, and an operation knob having two protrusions is fitted to three positions of a recess of the battery cover. In the two positions, the battery cover is locked in both positions. Furthermore, Patent Document 3 discloses a structure in which the arm plate attached to the cover is rotated about the center of the long-side screw, and the fitting portions provided at the both ends are respectively moved up and down. The fitting holes formed on the frame are fitted in opposite directions to lock the cover at two places of the frame. However, in Patent Document 1, the cover body is pivotally connected to the case body to close the cover portion, but the case body and the cover system are locked and locked at the left and right sides, so that the mechanism is complicated and the number of parts is large. Also more. Moreover, when the case body is accidentally dropped, the hinge portion is deformed or deformed by the impact. Moreover, when the hinge portion is damaged, the waterproof function of the accommodating portion is impaired. Further, in Patent Document 2, the two projections of the operation knob are directly fitted into the concave portion of the battery cover, so that when the mobile electronic device is accidentally dropped, the impact of the drop directly acts on the fitting portion of the operation knob and the battery cover. The fitting part is damaged or peeled off. At this time, the waterproof function of the battery compartment will be damaged. Further, in Patent Document 3, the structure in which the lock (fitting) is not released by the impact is employed, but the waterproofness inside the frame is not considered at all. Therefore, in this configuration, water is easily introduced between the frame and the slit of the cover. Prior Technical Documents 201138596 Patent Documents Special Spear!

The claws 40, 41, the claw mounting 4 36 37 is fitted, and the outer cover 22A (battery cover 22) is attached to the apparatus body 12 by the lock locking mechanism. Further, the width direction of the cover main body 23 (the X direction in Fig. 5) is left and right. In the end portion, side ribs 42, 43 which are erected in the thickness direction (the direction B in the fifth drawing) are continuously formed in the longitudinal direction. The side ribs 42, 43 are along the side of the opening portion 26a of the battery chamber 26. Fig. 6 is an exploded perspective view of the battery cover 22 when the inner cover 22B is laminated on the inner surface of the outer cover 22A. In the present embodiment, the inner cover 22B has a reinforcing plate 46 and an outer cover. 22A is made of different materials and is used as a reinforcing member. Adhesive tape 9 20113859 6 44 is provided on the side surface of the side cover 22A of the reinforcing plate 46 as an adhesive material; and the washer 48' is provided on the opposite side of the reinforcing plate 46 from the adhesive tape 44 as a sealing member. The inner side 22B is adhered to the outer side cover 22A by an adhesive tape 44. The adhesive tape 44 is made of, for example, a rectangular frame-shaped elastic material similar to a double-sided tape. The adhesive tape 44 has an outer cover 22A and a reinforcing plate 46. Adhesive and cushioning effect. Therefore, 'adhesive tape 44 is required to have adhesiveness and impact resistance. Moreover, 'this adhesive tape 44 has water resistance for waterproofing. The reinforcing plate 46 is used to reinforce the mechanical strength of the outer cover 22 A. Therefore, it is composed of a metal plate (for example, stainless steel) having abrasion resistance and impact resistance. The reinforcing plate 46 has a plate body 5〇 having an opening 5〇a at the center, and is formed in the plate body 50. The lid portion 51 on the upper side in the longitudinal direction (the Y direction in FIG. 6) protrudes from the pair of right and left projections 56 and 57 on the lower side in the longitudinal direction, and is formed in the width direction of the panel main body 50 (the X direction in FIG. 6).

Further, the projections 56, 57 of the reinforcing plate 46 reinforce the claws 40, 41 of the outer cover 22A. In addition, the cover portion 51 of the reinforcing plate 46 protects the locking mechanism 60, and the reinforcing plate 46 has wear resistance. Therefore, even if the frame portion of the side cover 22A is made of a synthetic resin and is worn by contact with other objects, the reinforcing plate 46 does not wear to the inside. Therefore, the battery compartment 26 covered by the battery cover 22 (refer to 8 10 201138596 3 The figure is not exposed, and the water repellency inside the battery compartment 26 can be maintained. Further, since the reinforcing plate 46 has a financial impact, even if the outer cover 2 made of synthetic resin is dropped or the like, the inner cover 22B containing the reinforcing plate 46 is not damaged. Therefore, the battery chamber 26 is not exposed, and the waterproofness inside the battery compartment% can be maintained. Further, the upper end portion of the right rib portion 54 of the reinforcing plate 46 in the longitudinal direction is provided with a slightly L-shaped shape and protrudes in the thickness direction (z direction in FIG. 6) on the inner surface side, and the deformation preventing member is prevented from being deformed by the metal zero. Yak 58. The cover portion 51 of the 敎61'__ plate 46 is protected. When the lever arm 6 moves in the growth direction, the end portion protrudes from the cover portion 51. Therefore, the deformation preventing metal fitting 58 has a function of preventing the inner side of the longitudinal direction of the longitudinal direction of the lever arm 61 (the right end side in the X direction in Fig. 6) from being deformed in the thickness direction (the z direction in Fig. 6). The loop 48 is composed of rubber or synthetic resin having no water ingress. This loop 48 is in the form of a rectangular frame having a rectangular opening 48& at the center. Further, the opening 48a is formed to be as large as or larger than the opening 5A of the reinforcing plate 46. This gasket 48 is adhered to one surface (surface opposite to the adhesive tape 44) of the reinforcing plate 46 by an adhesive tape or an adhesive (not shown). As a result, the outer cover 22A will be in a volumetric layer with the reinforcing plate 46 and the washer 48. Further, the gasket 48 is pressed to the peripheral wall surface 30 of the opening portion 26a of the battery chamber 26 at a specific pressure, whereby the reaction function is utilized to maintain the water-proof function of the battery chamber 26. Further, as described above, in the battery cover 22, the projections 56, 57 on the reinforcing plate 11 201138596 46 of the inner cover 22B protrude beyond the width direction of the claws 40, 41 of the outer cover 22A. Therefore, the milk 6, 57 will be hooked on the opening of the f pool chamber 26. [526a's lower end to reinforce the hook. Next, the lock mechanism 60 of this embodiment will be described. The lock mechanism 60' is a mechanism that presses the battery cover 22 against the apparatus body 12 side when the battery cover 22 covers the opening portion 26a of the battery chamber 26. With this locking action, the battery cover 22 is pushed to the apparatus body 12 side to maintain the waterproofness of the inside of the battery compartment 26. The locking mechanism 60' is movably disposed on the battery cover 22 as a rod member #61' which operates the lever arm 61 as an operation means of the operation knob 62' and is disposed on the apparatus body 丨2 and as the lever arm 61 When the operation 62 is moved, the engaging pins 34 and 35 of the both end portions (65a, 67) of the engaging lever arm 61 are referred to (refer to FIG. 3). Fig. 7 is an exploded perspective view of the lever arm 6 and the operation knob 63, and the operation knob 62. Figure 8 is an assembly diagram of the above parts. In the seventh and eighth figures of the beans, the lever arm 61 has a frame portion 65 having a rectangular frame shape including the first end portion 65a, and the frame portion & The slab is secreted and has a second end portion 67 extending horizontally from a portion of the upper portion (Z direction) of the flat portion. In this way, when the battery cover 22 closes the battery compartment 26, the lever arm is moved to the right (X direction) of the main figure 7, and the first end (10)a is engaged with the engaging pin 35 of the device II, (4) 2 end ο will be engaged when the pin 34. Further, the flat plate portion 66 of the lever arm 61 is provided with an operation pin 68 upright. On the other hand, the operation panel 63 is formed with a through hole 69. The operation panel 63 is attached to the operation gamma of the lever f61 by passing through the hole 2011 69 of the 201138596. The rod of the through hole 6 9 with respect to the center of the operation plate 63 is thus inserted into the operation pin 68 of the wheel, and is also eccentric with respect to the center = center. As a result, the rotary operation arm 61 moves in the long direction. Further, in addition to the through hole 69, the operation plate 63 is formed with a plurality of (four in the figure) through holes 70. The operation panel phantom is mounted in a state in which it is coupled to the operation knob 62 and cannot be rotated. The lever arm 6 is held in a state in which it can be moved in the width direction (the X direction in FIG. 6 and FIG. 6) with respect to the battery cover 22. However, the lever cannot be moved in the thickness direction (Z direction in Fig. 5) with respect to the battery cover. As a result, when the operation knob 62 is rotated, the lever arm 61 is moved in the longitudinal direction to be engaged with the engagement pins 34, 35. Further, the deformation preventing metal member 58 shown in Fig. 8 is a metal member which is prevented from being deformed by the depression of the second end portion 67 of the lever arm 61 or the like. This prevents deformation caused by an external force acting on the second end portion 67 of the lever arm 61 during long-term use. In the present embodiment, the one end side (second end portion 67) of the lever arm 6 is covered by the deformation preventing metal member 58. However, the present invention is not limited thereto. For example, the same metal parts may be used to cover both end portions (the first end portion 65a and the second end portion 67) of the rod f61. In this way, external force can be prevented from acting on the second end portion 65a and the second end portion 67 of the lever arm 61, respectively, and the end portions of the lever arm 61 are deformed. Fig. 9 is a plan view showing the battery cover 22 as seen from the inner surface side. 13 201138596 Then 1 beer department) and lock In the 9th figure, if the operation screw is rotated in the direction of arrow b, the lever arm 6 will move in the direction of arrow C. Thus, the nf6iy and the "part 67" will be engaged with the engaging pins 34, 35 (refer to the battery cover 22 of Fig. 3 and if the operating knob 62 is rotated in the opposite direction, the lever arm is in the opposite direction to the arrow c Move 'release the lock of the battery cover 22. Fig. 10A and Fig. _ are diagrams showing the operation state of the lever (four). The first diagram shows the lever arm 01 against the engagement pins 34, 35 (refer to the lock state of Fig. 3, the first _ indicates the locking state of the lever arm 61 with respect to the engaging pins 34, 35. As shown in Fig. 10A, in the unlocked state of the lever arm 61, the lever arm center does not engage with the engaging pins 34, 35. That is, in this state, the second end portion 65a and the second end portion 67 of the lever arm 61 are located away from the engaging pins 34, 35 in the longitudinal direction (X direction). In this state, the battery cover 22 is only The opening portion 263 covering the battery chamber 26 is not locked. As shown in FIG. 10B, when the knob 62 is rotated, the lever arm 61 is moved in the long direction (arrow c direction) by the operation panel 63 and the operation pin 68. In addition, the rotation of the operation knob 62 is actually in a state where the battery cover 22 covers the opening portion 26a of the battery chamber 26, and the rotation operation is performed. 62. In this way, the lever arm 61 moves in the longitudinal direction (X direction), and the first end portion 65a and the second end portion 67 (the A surface, the A surface in the 10A diagram) enter the engagement. The pins 34 and 35 are engaged on the lower side (Z direction). In this manner, the lever arm 61 and the engaging pins 34 and 35 are engaged with each other. By this engagement, the battery cover 22 shown in FIG. The opening portion 26a of the battery chamber 26 is closed. The first end portion 65a and the front end of the second end portion 67 are formed as 8 14 201138596 as a push-out surface for easy engagement with the engaging pins 34 and 35. In the embodiment, the second end portion 65a of the lever arm 61 and the upper surface of the second end portion 67 (the A surface and the A' surface in the FIG. 10A) are located slightly above the lowermost portions of the engaging pins 34 and 35 (the 1 position in the Z direction. In this manner, the first end portion 65a and the second end portion 67 are engaged with the card pin 34, 3S, and the lever arm 61 (and the battery cover 22) is used by the card. The reaction force of the pin 34, 35 is slightly moved downward (in the direction of the arrow D). By the movement of the lever arm 61 downward (in the direction of the arrow D), the battery cover 22 holding the lever arm 61 is pushed to the device. this 12 side. As such, the potential circle 48 will be reduced to the (four) wall (4) of the battery compartment 26 to maintain the waterproof function. In this case, if the _48 has _ sex, the _ water tilt can be further improved. In the middle, a metal rod having a circular cross-sectional shape is used, and 剖面 is not limited thereto. A cross-sectional polygon or an elliptical shape or a semi-circular shape may be used. Thus, the buckle is engaged with the engaging pin 34, The lever arm 61 is relatively easy to abut against the engaging pin Μ, the corner portion of the %, and moves downward (in the direction of the arrow D). Thus, in the present embodiment, the operation can be performed by rotating the battery cover. The rod f 61 is moved in the longitudinal direction, and the lever arm 61 is engaged with the two engaging pins Μ, % of the left and right ends in the width direction of the apparatus body 丨2. In the present embodiment, the towel rod (10) is not fixed to the device 12 or the battery cover 22 and is freely movable. Therefore, even if you accidentally drop the gear = 12, it is difficult to straighten, and 61 causes an impact. Therefore, the rod is deformed to keep the battery cover locked. In this way, the battery cover 22 will not be detached, and the battery (4) waterproof function can be maintained. 15 201138596 Moreover, when the operation knob 62 is operated to move the lever arm 61 to be engaged with the two engagement pins 34, 35 of the apparatus body 12, the end portion of the lever arm 61 (for example, the second end portion 67) is The deformation formed on the reinforcing plate 46 prevents the metal member 58 from being covered for protection. Thereby, even if it is used for a long period of time, the second end portion 67 of the lever arm 61 can be prevented from being deformed (for example, bent toward the apparatus body 12 side). Further, in order to attach the battery cover 22 to the apparatus main body 12, the battery cover 22 must be placed over the opening portion 26a of the battery chamber 26, and then the battery cover 22 is slid downward in the longitudinal direction (Y direction in Fig. 3). As a result, the claws 41, 41 of the battery cover 22 are fitted into the claw mounting portions 36, 37, and then the operation knob 62 is operated. As a result, the battery cover 22 closes the opening portion 26a of the battery chamber 26, and is further engaged with the engaging pins 34, 35 at two places to complete the locking. Further, at this time, the projections 56, 57 of the reinforcing plate 46 are also fitted into the opening portion 2 such as the wall surface 30, so that the assembling strength of the battery cover 22 can be enhanced. According to this embodiment, the locking mechanism 60 has a lever arm 61, an operation knob 62, and engaging pins 34, 35 provided in the apparatus body 12, and when the lever arm 61 is engaged with the engaging pins 34, 35, the battery cover 22 Since the reaction force originating from the engaging pins 34 and 35 is pushed to the apparatus main body 12 side, the waterproofness of the battery compartment 26 can be ensured. Further, according to the present embodiment, the apparatus main body 12 is made of an elastic material such as synthetic resin, and the gasket 48 of the battery cover 22 abuts against the wall surface 30 around the battery chamber 26, so that the battery cover 22 can be closed without gaps. The opening 26a of the battery chamber 26. Therefore, the gasket pressure can be ensured and the waterproofness of the battery chamber 26 can be maintained. Further, according to the present embodiment, the lever arm 61 is not fixed to the apparatus body 12 or the battery cover 22, so that the lever arm 61 is not easily directly impacted even if it is accidentally dropped. Therefore, the engagement of the lever arm 61 with the engaging pins 34, 35 is not easily removed, and the battery chamber 26 is not exposed and is completely protected.
