下面结合实施例具体说明本发明的技术方案。
实施例一
图 3至图 12所示为本实施例一的具体实施方案。
图 3所示为处理盒 2的立体视图， 21为设置在处理盒纵向方向的一端上的 旋转力驱动组件， 该驱动组件 21设置在感光元件的一端上。 所示处理盒 2的纵 向方向即为图示 X坐标方向， 由于感光元件沿所述处理盒的纵向方向设置， 故 所述感光元件的轴线方向与 X轴方向同向； Y方向为与 X方向垂直的另一方向， 即为本方案中将处理盒安装到电子成像装置的过程中处理盒的安装方向； Z方向 为与 X方向、 Y方向均垂直的方向。 图 4为沿所述感光元件的轴线 L1方向剖切的处理盒的部分剖视图， 可清楚 地显示所述驱动组件 21在处理盒 2内的设置情况。 如图所示， 211为沿所述处 理盒的纵向方向设置在处理盒 2内的感光元件； 212为设置在所述感光元件一端 上的感光元件轮毂， 所述感光元件轮毂外圆周上设置有用以传递动力的斜齿轮， 内部具有空腔，所述感光元件与所述感光元件轮毂相对固定连接，并且同轴设置; 213为本实施例的驱动组件的中间动力传递部件， 214为用于与设置在电子成像 装置内的旋转力驱动头啮合传递动力的旋转动力接收部件；其中中间动力传递部 件 213—端设置在所述感光元件轮毂的空腔内并与所述感光元件轮毂 212啮合传 递动力， 另一端与所述旋转动力接收部件 214啮合传递动力； 215为设置在所述 感光元件轮毂 212的一端上的侧板， 216为设置在侧板上并可相对于所述侧板 215 滑动的滑动件； 217为可使所述滑动件 216恢复原始状态的第一弹性元件。
所述旋转动力接收部件 214与电子成像装置内的旋转力驱动头 11啮合后， 将动力通过所述中间动力传递部件 213传递给所述感光元件轮毂 212， 从而驱动 所述感光元件 211旋转。
本发明中的所述驱动组件包括感光元件轮毂、 中间动力传递部件、旋转动力 接收部件、侧板、 以及轴线偏移调整机构； 所述轴线偏移调整机构设置于所述侧 板上并与所述侧板可相对滑动，所述轴线偏移调整机构包括所述滑动件以及第一 弹性元件。
图 5为本实施例的驱动组件 21的装配分解视图。 感光元件轮毂 212设置在 感光元件 211的端部上，中间动力传递部件 213—端与所述感光元件轮毂 212连 接， 另一端与所述旋转动力接收部件 214连接； 旋转动力接收部件 214具有接收 动力的卡爪 2141、 圆柱部分 2142以及凸台部分 2143， 所述凸台部分用以防止旋 转动力接收部件 214脱出； 侧板 215设置于所述感光元件轮毂 212的一端， 其上 具有滑轨 2151， 滑动件 216设置于所述侧板 215上， 侧板 215相对于感光元件 轮毂 212不移动； 滑动件 216具有与所述滑轨 2151配合的手柄端 2161， 手柄端 2161上还设置有第一弹性元件 217的放置槽 2162， 滑动件 216上还设置有与所 述旋转动力接收部件 214配合，并可带动旋转动力接收部件 214移动的内孔 2163， 内孔 2163与旋转动力接收部件上的圆柱部分 2142配合， 所述圆柱部分 2142可 相对于内孔 2163进行沿感光元件轴向方向滑动； 本实施例还通过压紧件 218将 滑动件手柄端 2161以及第一弹性元件 217限制在侧板 215的滑轨 2151内，压紧 件 218与侧板 215相对固定设置或者侧板 215上设置有压紧部分；所述滑轨可以 设置成滑槽， 也可以是键， 相应在滑动件 215 上设置相匹配的滑槽， 使滑动件 216可相对于侧板 215滑动。
图 6用于具体说明中间动力传递部件 213与感光元件轮毂 212以及旋转动力 接收部件 214之间的连接关系。如图 6所示， 感光元件轮毂 212内圆周方向上设 置有多个受力柱 2121 ; 中间动力传递部件 213包含有第一端部球形部分 2131、 第二端部球形部分 2133 以及中间连接部分 2132， 其中第一端部球形部分 2131 以及第二端部球形部分 2133上分别设置有第一动力传递部分 21311以及第二动 力传递部分 21331， 所述动力传递部分 21311以及 21331沿所述中间动力传递部 件 213的径向方向伸出； 旋转动力接收部件 214内部为中空， 其端部上设置有接 收动力的并在圆周方向上对称设置的卡爪 2141， 其内部沿内圆周方向上设置有 多个受力部 2144; 动力传递部分 21311设置于受力柱 2121之间的间隙中， 动力 传递部份 21331设置于受力部 2144之间的间隙中； 中间动力传递部件 213被限 制在感光元件轮毂 212以及旋转动力接收部件 214之间；由于中间动力传递部件 213的两个端部为球形部分，中间动力传递部件 213可以相对于感光元件轮毂 212 的轴线以及旋转动力接收部件 214的轴线发生任意角度的偏摆；所述第一动力传 递部分 21311与受力柱 2121啮合传递动力， 所述第二动力传递部分 21331与受 力部 2144啮合传递动力。
图 7至图 10分别描述了驱动组件所处的两种状态。 图 7为驱动组件所处的 初始状态的立体视图，图 8为图 7的剖视图。当处理盒在安装到电子成像装置前， 驱动组件处于如图 7和图 8所示的状态； 当处理盒安装到位之后， 驱动组件处于 如图 9和图 10所示的状态 （工作状态）。 处理盒安装之前， 在第一弹性元件 217 的自然伸长的作用下，通过第一弹性元件 217使滑动件 216保持在初始状态， 即 滑动件 216的轴线 L3与感光元件轮毂轴线 L1发生偏移的状态， 并且旋转动力 接收部件 214被保持在内孔 2163内， 同时旋转动力接收部件 214的轴线与滑动 件 216的轴线 L3同轴， 此时旋转动力接收部件 214亦随着滑动件 216相对于感 光元件轮毂的轴线 L1发生偏移， 即轴线 L1与轴线 L3不重合但相对平行； 由于 中间动力传递部件 213被限制在感光元件轮毂 212与动力传递部件 214之间，并 且与两者具有相互配合的关系，当旋转动力接收部件 214处于图 8所示的初始位 置时，旋转动力接收部件 214驱使中间动力传递部件 213相对于感光元件轮毂的 轴线 L1发生倾斜， 同时也相对于旋转动力接收部件 214的轴线 L3发生倾斜。 此时， 驱动组件处于初始状态， 中间动力传递部件 213的轴线 L2相对于感光元 件轮毂的轴线 L1和旋转动力接收部件 214的轴线 L3发生倾斜， 即 L2与 Ll、 L2与 L3之间均形成有夹角。 当将处理盒安装到电子成像装置的过程中， 滑动件 216沿处理盒安装方向的反方向受到一个外力 F的作用，力 F通过驱使滑动件 216 克服第一弹性元件 217的弹性力而使滑动件 216沿着处理盒装机方向的反方向在 滑轨 2151内滑动； 此时， 旋转动力接收部件 214亦随着滑动件 216进行移动， 并带动中间动力传递部件 213逐渐摆正（即 L2与 Ll、 L2与 L3之间的夹角角度 逐渐变小）， 并且中间动力传递部件 213上与所述旋转动力接收部件啮合的一端 向所述旋转动力接收部件靠近； 最后， 当处理盒安装到位之后， 外力 F克服第一 弹性元件 217的弹性力并使其压缩， 使得中间动力传递部件 213、 旋转动力接收 部件 214以及滑动件 216保持在如图 9和图 10所示的状态， 即驱动组件的工作 状态； 此时， 中间动力传递部件的轴线 L2、 旋转动力接收部件 L3与感光元件轮 毂的轴线 L1同轴。 同时， 处理盒装机从初始状态到工作状态的这个过程中， 中 间动力传递部件 213从倾斜到摆正，使旋转动力接收部件 214在处理盒的纵向方 向上具有一定的位移量，即可使旋转动力接收部件 214在处理盒的纵向方向上进 行伸出。
图 11a至图 11c所示为处理盒安装到电子成像装置中驱动组件与旋转力驱动 头啮合的过程示意图。如图 11a所示， 11为设置在电子成像装置内的旋转力驱动 头， 13为驱动旋转力驱动头 11旋转的驱动齿轮， 12为电子成像装置的右侧壁， 14为电子成像装置后侧壁， 其中旋转力驱动头 11和驱动齿轮 13都设置在电子 成像装置的右侧壁 12上， 141为后侧壁 14上与处理盒的装机方向相对的内侧面。 图 11a所示为处理盒在装机前， 驱动组件所处的初始状态， 中间动力传递部件 213相对于感光元件轮毂的轴线 L1以及旋转动力接收部件 214的轴线 L3发生倾 斜， 旋转动力接收部件 214的轴线 L3相对于感光元件轮毂的轴线 L1发生偏移， 并且第一弹性元件 217处于自然伸长状态使得滑动件 216保持在初始状态，此时 旋转动力接收部件 214处于回缩状态。 当处理盒沿图示 Y方向进行安装， 逐渐 向电子成像装置内侧面 141靠近，由于旋转动力接收部件 214—直处于回缩状态， 处理盒安装过程中， 旋转动力接收部件 214不会与旋转力驱动头 11产生干涉； 继续处理盒的安装， 滑动件 216的端面 2161首先触碰到电子成像装置的内侧面 141 , 内侧面 141便对滑动件 161产生一个力 F的作用， 力 F的作用方向与处理 盒的装机方向 Y方向相反， 如图 lib所示， 此时旋转动力接收部件 214与旋转 力驱动头 11同轴， 但是仍然未能相互啮合， 相互之间不存在干涉， 旋转动力接 收部件处于回缩状态； 处理盒继续安装， 力 F促使滑动件 216沿 Y方向的反方 向相对于感光元件 211滑动，并通过旋转动力接收部件 214带动中间动力传递部 件 213逐渐摆正，中间动力传递部件 213在摆正的过程中促使旋转动力接收部件 214沿处理盒的纵向方向伸出， 即如图 11c所示的 X方向。 图 11c所示为处理盒 安装到位的状态， 即处理盒处于工作状态， 此时旋转动力接收部件 214与旋转力 驱动头 11实现啮合， 旋转力驱动头 11、 旋转动力接收部件 214、 中间动力传递 部件 213都与感光元件轮毂的轴线 L1同轴。 当启动电子成像装置， 驱动齿轮 13 转动驱动旋转力驱动头 11转动， 从而通过旋转动力接收件 214， 中间传递部件 213以及感光元件轮毂 212将动力传递给感光元件， 使感光元件转动。
图 12a至图 12c所示为将处理盒从电子成像装置拆卸下来的过程中驱动组件 与旋转力驱动头脱离啮合的过程示意图。如图 12a所示， 将处理盒从电子成像装 置中沿与安装方向 （Y方向） 相反的方向 （即沿图示 Y'方向） 拆卸下来。 在处 理盒的逐渐拆卸过程中， 由于力 F逐渐撤销，第一弹性元件 217产生的弹性回复 力的方向与处理盒拆卸的方向相反，第一弹性元件 217产生的弹性回复力作用于 滑动件 216， 从而使中间动力传递部件 213发生偏摆， 如图 12b所示， 同时弹性 元件所具有的回复力使滑动件 216在滑轨 2151内沿处理盒拆卸方向的反方向滑 动， 再通过中间动力传递部件发生偏摆时带动旋转动力接收部件 214沿 X方向 的反方向 （即图示 X'方向）缩回， 并与旋转力驱动头 11脱离啮合， 作用力 F逐 渐减弱甚至消失； 继续拆卸处理盒， 处理盒与电子成像装置完全脱离接触， 如图 12c所示。
通过本实施例的实施方式，可使处理盒在安装到电子成像装置的过程中不与 旋转力驱动头发生发生干涉； 在处理盒的安装或拆卸过程中， 在滑动件的端面仍 然与电子成像装置的内侧面保持接触的过程中，旋转动力接收部件 214相对于旋 转力驱动头 11在处理盒的安装方向上不发生相对移动;仅旋转动力接收部件 214 相对于旋转力驱动头 11在轴向上发生相对移动， 并与之啮合或脱离啮合， 从而 使处理盒装机顺利。
实施例二

图 14所示为中间传递部件 223与旋转动力接收部件 224之间啮合传递动力 的具体结构视图。 如图所示， 中间传递部件 223 内圆周上设置有多个突出部分 2232, 相应地， 在旋转动力接收部件 224的外圆周上设置有多个突柱部分 2245; 当中间传递部件 223与旋转动力接收部件 224啮合时， 突出部分 2232与突柱部 分 2245相互啮合， 可实现相互间的动力传递。 图 15所示为中间传递部件 223与 旋转动力接收部件 224啮合时啮合部分的横切面视图。
下面详细描述将利用本实施例二的驱动组件的处理盒安装到电子成像装置 以及从电子成像装置中拆卸的过程。
图 16a至图 16c所示为处理盒安装到电子成像装置中驱动组件与旋转力驱动 头啮合的过程示意图。 图 16a所示为所述的驱动组件 22安装在处理盒 2上所处 的初始状态的视图，中间动力传递部件 223在滑动件 226的作用下保持在回缩状 态，第二弹性元件 228处于受压缩状态； 在第一弹性元件 227以及滑动件 226的 作用下， 旋转动力接收部件 224保持在与感光元件轮毂的轴线 L1相对偏移的状 态。 将处理盒沿 Y方向安装到电子成像装置中， 滑动件 226的端面 2261首先触 碰到电子成像装置的内侧面 141， 此时， 内侧面 141对滑动件 226产生一个与处 理盒安装方向相反的作用力 F， 如图 16b所示。 继续安装处理盒， 在力 F的作用 下，第一弹性元件 227逐渐被压缩， 滑动件 226克服第一弹性元件 227的弹性力 沿与处理盒装机方向相反的方向进行相对滑动，并带动旋转动力接收部件 224沿 与处理盒装机方向相反的方向相对移动， 而此时， 中间动力传递部件随着处理盒 的安装与处理盒一起向电子成像装置内侧面靠近，即中间动力传递部件 223与旋 转动力接收部件 224相对移动， 其轴线 L2与 L3相互靠近； 随着处理盒的安装， 滑动件 226在滑动过程中， 滑动件 226的底面 2264与中间动力传递部件 223的 端面逐渐脱离接触，中间动力传递部件 223在第二弹性元件 228的回弹力的作用 下沿处理盒的纵向方向 （即图示 X方向）伸出。 当处理盒安装到位时， 如图 16c 所示， 为驱动组件 22所处的工作状态。 中间动力传递部件 223在第二弹性元件 228的回弹力作用下沿图示 X方向伸出， 并与旋转动力接收部件 224啮合， 两者 啮合后， 中间动力传递部件继续伸出， 并促使旋转动力接收部件 224—起沿 X 方向伸出与设置在电子成像装置中的旋转力驱动头 11啮合。 此时， 感光元件轮 毂 222、 中间动力传递部件 223、旋转动力接收部件 224与旋转力驱动头 11均处 于同轴的状态。当启动电子成像装置后，驱动齿轮 13驱动旋转力驱动头 11转动， 旋转力驱动头通过与旋转动力接收部件 224的卡爪 2241啮合将动力传递给旋转 动力接收部件 224， 在通过旋转动力接收部件 224与中间动力传递部件 223的啮 合， 以及中间动力传递部件 223与感光元件轮毂之间的啮合， 从而将旋转动力传 递给感光元件轮毂， 从而达到通过感光元件轮毂 222 驱动感光元件旋转的目的 (感光元件轮毂与感光元件之间为紧配合关系， 并且同轴）。
图 17a至图 17c所示为将处理盒从电子成像装置拆卸中驱动组件与旋转力驱 动头脱离啮合的过程示意图。将处理盒沿与处理盒安装方向相反的方向（即图示 Y'方向） 拆卸， 如图 17a所示。 随着处理盒的拆卸， 电子成像装置的内侧面 141 对滑动件 226的力 F逐渐减弱甚至消失，滑动件 226在第一弹性元件 227的回弹 力的作用下沿与处理盒拆卸方向相反的方向滑动， 斜面 2263作用于中间动力传 递部件 223， 并使其沿轴线 L1方向回缩， 同时第二弹性元件 228受到压缩； 在 中间动力传递部件 223的回缩过程中， 逐渐与旋转动力传递部件 224脱离啮合， 当滑动件 226的底面 2264与中间动力传递部件 223的端面抵接时， 可使中间动 力传递部件保持在回缩的状态； 中间动力传递部件 223与旋转动力接收部件 224 脱离啮合后， 旋转动力传递部件 224在第三弹性元件 229的作用下沿 X方向的 反方向 （即图示 X'方向） 回缩， 如图 17b所示。 继续拆卸处理盒， 处理盒与电 子成像装置完全脱离接触， 如图 17c所示， 实现将处理从电子成像中拆离。 实施例三
图 18至图 21为本发明的实施例三。
图 18所示为实施例三的驱动组件 23的装配视图。 232为设置于感光元件纵 向方向一端的感光元件轮毂， 具有轴线 Ll， 其内部设置有空腔， 还设置有底部 2321 , 底部上开设有非圆形孔 2322; 233为中间动力传递部件， 具有轴线 L2， 设置在感光元件轮毂 232中， 并与感光元件轮毂同轴； 中间动力传递部件 233包 含有三部分， 分别为中间连接件 2331、端部连接件 2332以及插销 2333， 插销可 对中间动力传递部件 233进行轴向限位； 234为旋转动力接收部件， 其上设置旋 转动力接收端部，旋转动力接收端部上设置有可与设置在电子成像装置内旋转力 驱动头啮合传递动力的卡爪 2341， 旋转动力接收部件的另一端为圆柱部分 2343 并与中间连接件 2331连接； 侧板 235设置在感光元件轮毂的一端上， 侧板 235 上还设置有滑动件 236， 侧板 235上设置有滑槽， 滑动件 236在侧板 235上的设 置情况与实施例一的设置情况一样；第一弹性元件 237设置在侧板 235与滑动件 236之间， 其一端与侧板 235抵接， 另一端与滑动件 236抵接； 滑动件 236具有 端面 2361， 内孔 2362， 内端面 2363， 斜面 2364， 以及底面 2365; 旋转动力接 收部件 234贯穿设置于滑动件 236的内孔 2362中， 圆柱部分 2343与内孔 2362 配合， 旋转动力接收部件 234可相对于内孔 2362滑动； 在第一弹性元件 237的 作用下， 使滑动件 236保持在与感光元件轮毂 232的轴线 L1相对偏移的状态； 第二弹性元件 238—端与感光元件轮毂 232的底部 2321抵接， 另一端与中间动 力传递部件 233的端部连接件 2332抵接； 当滑动件 236处于偏移状态时， 其底 面 2365抵接于中间动力传递部件 233上的一部分， 使中间动力传递部件 233整 体处于回缩状态， 第二弹性元件 238 处于被压缩状态； 由于旋转动力接收部件 234与中间连接部件 2331连接， 因而旋转动力接收部件 234受到中间连接部件 2331的牵拉也处于回缩状态。 图 18所示即驱动组件 23所处的初始状态。
图 19所示为中间动力传递部件 233与旋转动力接收部件 234的具体结构与 连接关系。 中间连接件 2331的两端设置有具有限位作用的限位导轨， 分别设置 为槽 23311以及 23312， 两个槽相互垂直设置， 所述槽可设置为 T型槽结构； 端 部连接件 2232的一端设置有可与槽 23312配合的键 23322， 所述键相应为 T型 键， 另一端设置有非圆形柱 23321， 非圆形 23321可与感光元件轮毂 232内的非 圆形孔 2322配合传递动力， 非圆形柱 23321上设置有孔 23323， 用以放置插销 2333； 旋转动力传递部件 234的一端为动力接收部分， 端部设置有卡爪 2341， 另一端设置有可与 T型槽 23311配合的 T型键 2342。 中间连接件 2331、 端部连 接件 2332与旋转动力传递部件 234之间的连接具有联轴器的功能； T型键与 T 型槽之间可相对滑动； T型具有限位的作用， 可防止部件之间相互脱离。
当然，本实施中也可以将 T型槽分别设置在旋转动力接收部件 234以及端部 连接件 2332上， 相应的在中间连接部件 2331的两端上设置 T型键。
以上所述 T型槽与 T型键的配合， 仅仅是本发明优选实施方式， 还可以是 其他的实施方式， 所述 T型可以对称， 可以不对称； 所述键槽之间可以是平面接 触也可以是圆弧面接触。键与槽之间的配合需要可相对滑动的同时， 在各部件的 轴线方向上有一定的限位作用， 并且可相互配合传递动力。
本实施例中， 非圆形孔与非圆形柱用于相互配合传递动力， 所述非圆形孔设 置为方形孔， 所述非圆形柱设置为方向柱。
下面详细描述将利用本实施例三的驱动组件的处理盒安装到电子成像装置 以及从电子成像装置中拆卸的过程。
图 20a至图 20c所示为处理盒安装到电子成像装置中驱动组件与旋转力驱动 头啮合的过程示意图。 图 20a所示为驱动组件 23处于初始状态的视图， 旋转动 力接收部件 234的轴线为 L3， 此时， 轴线 L3相对于感光元件轮毂的轴线 L1以 及中间动力传递部件的轴线 L2偏移， 将处理盒沿图示 Y方向进行安装， 驱动组 件处于初始状态时， 旋转动力接收部件 234处于回缩状态， 使得处理盒安装时， 旋转动力接收部件 234不与设置在电子成像装置内旋转力驱动头 11产生干涉。 如图 20a所示， 12为电子成像装置的右侧壁， 14为电子成像装置的后侧壁， 旋 转力驱动头 11设置在右侧壁 12上，驱动齿轮 13用于驱动旋转力驱动头 11转动。 将处理盒沿 Y方向进行安装， 滑动件 236的端面 2361首先与电子成像装置的后 侧面 141接触， 后侧壁 14便对滑动件 236产生作用力 F， 如图 20b所示。 处理 盒继续安装，在作用力 F的作用下，使得滑动件 236沿与处理盒装机方向相反的 方向滑动， 并逐渐使第一弹性元件 237压缩； 当滑动件 236移动到一定程度， 其 底面 2365与中间连接件 2331脱离接触，中间动力传递部件 233便可在第二弹性 元件 238的回弹力作用下沿感光元件轮毂的轴线 L1方向伸出， 同时推动旋转动 力接收部件 234沿处理盒的纵向方向 （即图示 X方向） 伸出； 当处理盒安装到 位之后，旋转动力接收部件 234伸出与电子成像装置内的旋转力驱动头 11啮合， 如图 20c所示， 即驱动组件处于工作状态。 启动电子成像装置后， 驱动齿轮 13 驱动旋转力驱动头 11旋转， 并带动旋转动力接收部件 234旋转， 从而通过中间 动力传递部件带动感光元件轮毂 232转动，最后通过感光元件轮毂 232带动设置 在处理盒内的感光元件转动。 此时， 感光元件 231、 感光元件轮毂 232、 中间动 力传递部件 233、 旋转动力接收部件 234以及旋转力驱动头 11的轴线处于基本 同轴的状态。
图 21a至图 21c所示为将处理盒从电子成像装置拆卸中驱动组件与旋转力驱 动头脱离啮合的过程示意图。如图 21a所示， 将处理盒沿与处理盒安装方向相反 的方向 （即图示 Y'方向）拆离电子成像装置。 随着处理盒的移动， 后侧壁 14对 滑动件 236的作用力 F逐渐减弱甚至消失，滑动件 236在第一弹性元件 237的回 弹力作用下沿与处理盒拆卸方向相反的反向移动， 并且带动旋转动力接收部件 234滑动， 使旋转动力接收部件 234相对与中间动力传递部件 233的轴线偏移； 同时， 滑动件 236在滑动的过程中， 其斜面 2364与中间动力传递部件 233上的 部分抵接，促使中间动力传递部件 233克服第二弹性元件 238的弹性力回缩， 同 时中间动力传递部件 233在随着处理盒移动的过程中带动旋转动力接收部件 234 沿图 21b所示 X'方向缩回。 如图 21b所示， 驱动组件 23恢复初始状态， 旋转动 力接收部件 234与电子成像装置的旋转力驱动头 11脱离啮合， 继而将处理盒顺 利从电子成像装置拆离， 如图 21c所示。
本发明中的方案中，若电子成像装置中的旋转力驱动头 11的轴线 L4到电子 成像装置中的内侧面 141的距离为 hl， 由于旋转动力接收部件 214 (224或 234) 沿处理盒纵向方向伸出与所述旋转力驱动头 11啮合传递动力， 为保证两者之间 的顺利啮合， 所述旋转动力接收部件的轴线 L3到所述滑动件 216 (226或 236) 的端面 2161 (2261或 2361 ) 的距离 h2被设置成与 hi相等， 如图 11a和图 lib 所示。所述电子成像装置中的旋转力驱动头 11的轴线 L4到电子成像装置中的内 侧面 141的距离为 hi即是轴线 L4到外作用力 F作用点的距离。
通过本发明的实施方式，可使处理盒顺利安装到电子成像装置中而不与电子 成像装置的旋转力驱动头产生干涉而导致处理盒无法安装到位的问题。
