接下来结合图4至图7介绍显影盒10a被成像设备的检测单元100检测的动作过程。
如图6所示,在本实施例中,显影盒10a处于未被使用过的状态时,传动件4a处于第二位置(初始位置),弹性件5a处于被压缩的状态,被检测构件6a处于未触发检测单元100的状态。
使用者将显影盒10a安装至成像设备中,联接件21a与成像设备的驱动传递构件联接。当成像设备开始运作时,惰轮24a接收联接件21a的驱动力并带动凸轮构件3a旋转,随着凸轮构件3a的旋转,受力部41a在第一凸轮部33a的推动下从第一凸轮部33a的顶部沿着第一引导面35a向第一凸轮部33a的根部移动,此时在弹性件5a的弹性恢复力作用下,传动件4a向右侧滑动,被检测构件6a在传动件4a的带动下转动并触碰成像设备的检测单元100。
随着凸轮构件3a的转动,传动件4a的受力部41a在第二凸轮部34a的推动下沿着第二凸轮部34a的第二引导面36a从凸轮部的根部向第二凸轮部34a的顶部移动,此时传动件4a向左滑动并带动被检测构件6a转动,被检测构件6a脱离检测单元100。随着受力部41a沿着第一引导面35a从第二凸轮部34a的顶部向第二凸轮部34a的根部移动,在弹性件5a的弹力恢复力作用下,传动件4a向右滑动并带动被检测构件6a转动,被检测构件6a二次触碰检测单元100。随着凸轮构件3a的旋转,受力部41a沿着凸轮构件3a的端面移动并最终落入缺口部71a中(如图7所示),凸轮构件3a继续旋转,而传动件4a不受推动,检测完成。
凸轮部的数量可以根据需要拨动检测单元100的次数进行设置,例如需要拨动一次时可以设置一个,需要拨动多次时可以设置多个;不同凸轮部的结构也可以是不完全相同,其可以根据推动传动件的力度、幅度等进行设置,以此可以区分不同型号或不同容量的显影盒等。
具有上述结构的显影盒10a,传动件4a至少一部分在盒体1a的长度方向L上移动。参考图7可知,传动件4a在盒体1a的长度方向L上移动的距离为d1,该距离d1与凸轮部的突出量(即凸轮部的根到凸轮部的顶部的距离)相同或大于凸轮部的突出量。
具有上述结构的显影盒10a,无需通过搅拌构件15a的旋转轴传递驱动被检测构件6a的作用力,从而消除了搅拌构件15a的旋转轴容易产生变形甚至断裂的风险。采用滑动的方式实现将显影盒10a第一端的驱动力传递至显影盒10a的第二端,解决了搅拌构件15a的旋转轴变形导致的驱动力传递延时的问题,提升了检测精度。同时,显影盒10a所需的扭力也会大大降低,显影盒10a工作更加稳定。
在一些实施例子中,被检测构件与传动件4a一体成型,被检测构件设置在传动件4a的端部并随着传动件4a的移动而移动,从而能够触发成像设备的检测单元100。
在一些实施例子中,被检测构件6a设置成滑动件,依靠传动件4a的推动力进行滑动。
在一些实施例子中,弹性件5a不与传动件4a连接,而是设置成与被检测构件6a连接,通过被检测构件6a推动传动件4a从第二位置移动向第一位置移动。
在一些实施例子中,被检测构件不与传动件接触,即二者可以间隔开预设的距离,只要传动件4a移动时可驱动被检测构件6a即可。
在一些实施例子中,离合机构还可以设置在驱动力接收单元2a与凸轮构件3a之间,通过断开驱动力接收单元2a与凸轮构件3a之间的驱动力传递而间接切断向传动件4a传输驱动力。
在一些实施例子中,驱动构件3a为与驱动力接收单元2a啮合的齿条结构,该齿条结构接收驱动力而移动,并能够推动传动件4a在显影盒的长度方向上移动。
在一些实施例子中,传动件4a的初始位置为第一位置,传动件4a从第一位置移动至第二位置时驱动被检测构件6a触碰成像设备的检测单元。
在一些实施例子中,被检测构件6a在初始位置时可以与检测单元100的传动机构200接触或不接触。
在一些实施例子中,根据设计需要将上述各变形方式进行组合。
实施例2
本实施例是在实施例1和其变形例的基础上作改进,实施例2的显影盒的形状结构与实施例1的显影盒的形状结构基本相同,相同部分不再赘述,以下主要介绍其不同之处。
如图8和图9所示,在本实施例中,凸轮部的突出方向与实施例1中凸轮部的突出方向相反,在本实施例中凸轮部具有两个,分别为第一凸轮部33b和第二凸轮部34b,以下以第一凸轮部33b为例进行说明。第一凸轮部33b从主体部31b的端面向靠近第一侧壁11b的方向突出并能够推动传动件4b的受力部41b。
弹性件5b向传动件4b的施力方向为向左侧方向,弹性件支撑部51b位于弹性件5b的右侧。传动件4b的初始位置位于第一位置,在该第一位置,传动件4b的受力部41b与主体部31b右侧端面抵接。
在本实施例中,被检测构件6b被配置为沿盒体的上下方向摆动,具体的被检测构件6b设置有力接收部61b、连接部62b以及检测部63b,连接部62b通过一枢轴可摆动地连接在第二端盖102b上,力接收部61b从连接部62b向靠近传动件4b的方向延伸,力接收部61b还设置有迫压面611b,传动件4b通过抵压该迫压面611b而使得被检测构件6b绕轴转动。被检测部63b设置在连接部62b的另一侧,当迫压面611b受传动件4b推压时,检测部63b向上翘起,以能够触发成像设备的检测单元100。
可选择的,被检测部63b的移动方向可以根据检测部63b相对成像设备的检测单元100的位置来进行设置。
接下来结合图8和图9介绍显影盒10b被成像设备的检测单元100检测的动作过程。
如图8所示,在本实施例中,显影盒10b处于未被使用过的状态时,传动件4b处于第一位置(初始位置),弹性件5b处于未被压缩的状态,被检测构件6b处于未触发检测单元100的状态。
当成像设备开始运作时,凸轮构件3b通过第二齿轮部32b接收驱动力旋转,在第一凸轮部33b的推动下,受力部41b从第一凸轮部33b的根部沿着第二引导面36b向第一凸轮部33b的顶部移动,此时传动件4b受力向右滑动。如图9所示,传动件4b处于第二位置,弹性件5b被压缩,传动件4b抵压被检测构件6b的迫压面611b使得被检测构件6b转动,检测部63b向上翘起触碰成像设备的检测单元100。
随着受力部41b从第一凸轮部33b的顶部沿着第一引导面35b向第一凸轮部33b的根部移动时,在弹性件5b的弹性恢复力作用下,传动件4b受力向左移动,传动件4b不再迫压被检测构件6b,被检测构件6b的被检测部63b可在自身重力作用下向下移动并恢复至初始状态。当第二凸轮部34b推动传动件4b的受力部41b时,被检测构件6b二次触碰检测单元100,最终完成检测。
在一些实施方式中,显影盒还设置有弹性复位件,该弹性复位件向被检测构件6b施加弹性力,从而使得被检测构件6b能够恢复至初始状态。具体的弹性复位件可以是以压缩弹簧,压缩弹簧沿向上方向支撑被检测构件6b的力接收部61b,使得被检测构件6b处于初始位置。
在其它的一些实施方式中,根据设计需要将上述各变形方式进行组合。
实施例3
本实施例是在实施例1及其变形例的基础上作改进,实施例3的显影盒的形状结构与实施例1的显影盒的形状结构基本相同,相同部分不再赘述,以下主要介绍其不同之处。

具体的,凸轮构件3c的旋转轴线与联接件21c的旋转轴线是垂直设置的,该凸轮构件3c的第二齿轮部32c为第一锥齿部,其与设置在搅拌构件齿轮上的第二锥齿部38c啮合。凸轮构件3c的凸轮部33c设置在凸轮构件3c上方侧,该凸轮部33c沿主体部31c的径向方向向外延伸。
在本实施例中,离合机构包括设置在凸轮构件3c主体部31c圆周外侧的缺齿部37c,当缺齿部37c旋转至面对第二锥齿部38c时,第二锥齿部38c与第一锥齿部32c之间的驱动力传递被切断。
传动件4c的受力部41c与凸轮部33c相比位于更靠近第二侧壁12c的位置。在本实施例中,显影盒处于未被使用的状态时,传动件处于第一位置(如图10所示的位置),受力部41c与凸轮部的根部抵接。当凸轮构件3c的第二齿轮部32c接收驱动力旋转时,凸轮部33c推动受力部41c,传动件4c向右滑动,带动被检测构件6c转动,进而触发成像设备的检测单元100,如图11所示,传动件4c处于第二位置。随着凸轮构件3c的旋转,受力部41c从凸轮部33c的顶部向凸轮部33c的根部移动,传动件4c在弹性件5c的弹性恢复力作用下向左滑动并带动被检测构件6c摆动,被检测构件6c脱离检测单元100,检测完成。
在一些实施方式中,第二锥齿部可以设置在联接件21c、显影辊齿轮22c、送粉辊齿轮23c或惰轮24c上。
在一些实施方式中,传动件4c的受力部41c与凸轮部相比位于更远离第二侧壁12c的位置。
在其它的一些实施方式中,根据设计需要将上述各变形方式进行组合。

传动件4d包括受力部41d和杆部42d,杆部42d的中部以可上下摆动的方式与盒体1d连接,这样的连接例如通过一轴部与轴孔的连接。受力部41d设置在杆部42d的第一端,且该受力部41d位于主体部31d的旋转轴线的上方,以使得凸轮部能够向上推动受力部41d。
驱动构件为凸轮构件3d,凸轮构件3d的旋转轴线与联接件21d的旋转轴线平行设置,凸轮部沿着主体部31d的径向方向突出,在本实施例中,凸轮部具有两个,分别为第一凸轮部33d和第二凸轮部34d,第一凸轮部33d和第二凸轮部34d之间形成有凸轮部的根部。
弹性件5d支撑在杆部42d的第二端,设置在杆部42d第二端的下方侧。
被检测构件6d与传动件4d的第二端固定连接,以能够随着传动件4d的摆动而摆动。

在本实施例中,显影盒未被使用的状态下,传动件4d处于第二位置(如图12a所示),受力部41d与第一凸轮部33d的顶部抵接,弹性件5d处于被压缩的状态,被检测构件6d处于未触发检测单元的状态。
当成像设备开始运作时,随着凸轮构件3d旋转,传动件4d的受力部41d沿着第一凸轮部33d的第一引导面35d向根部移动,在弹性件5d的弹性恢复力作用下,杆部42d的第二端向上抬升并带动被检测构件6d向上移动,被检测构件6d触发成像设备的检测的单元,传动件处于第一位置(如图12b所示的位置)。
随着凸轮构件3d旋转,在第二凸轮部34d推动传动件4d的受力部41d的过程中,受力部41d先向上移动后向下移动,同步的,被检测构件6d向下移动脱离检测单元100后向上移动再次触碰检测单元100,进而实现检测。
图13a示出了传动件4d处于第二位置时传动件4d的位置状态;图13b示出了传动件4d处于第一位置时传动件4d的位置状态。如图13a所示,传动件4d处于第二位置时,传动件4d的一末端在显影盒的长度方向L上到摆动中心的距离为d2。传动件4d从第二位置摆动至第一位置时,如图13b所示,传动件4d的一末端在显影盒的长度方向L上到摆动中心的距离为d3,d3小于d2,传动件4d的一末端在显影盒的长度方向上的移动距离为d2与d3的差值。

接下来结合图14a和图14b介绍显影盒被成像设备的检测单元100检测的动作过程。
在本实施例中,显影盒处于未被使用的状态下,传动件4e处于第一位置(图14a所示出的位置),受力部41e与凸轮主体的圆周侧面相抵接,弹性件5e处于不受压缩的状态。

当传动件4e的受力部41e越过第一凸轮部33e的顶部时,在弹性件5e的弹性恢复力作用下,杆部42e的第一端向显影盒的后方移动,杆部42e的第二端带动被检测构件6e向前方脱离检测单元100的方向移动,当第二凸轮部34e推动受力部41e时,传动件4e和被检测构件6e的动作过程和第一凸轮部33e推动受力部41e时的动作过程相同,其结果是成像设备的检测单元100被再次触发,进而实现检测。
图15a示出了传动件4e处于第一位置时传动件4e的位置状态;图15b示出了传动件4e处于第二位置时传动件4e的位置状态。如图15a所示,传动件4e处于第一位置时,传动件4e的其中一部分a在显影盒的长度方向L上到摆动中心的距离为d4。传动件4e从第一位置摆动至第二位置时,如图15b所示,传动件4e的一部分a在显影盒的长度方向L上到摆动中心的距离为d5,d5小于d4,传动件e的一部分a在显影盒的长度方向L上的移动距离为d4与d5的差值。

在其它的一些实施方式中,柔性传动件还可以是链条、橡胶带等。
在其它一些实施方式中,支撑件还可以是固定在盒体上的部件。例如,可以将本实施例中的转动体61f替换成一固定件,固定件两端与盒体1f固定连接,并且该固定件的具有光滑表面,柔性带套装在该光滑表面上以能够相对固定件滑动,进而使得设置在柔性带上的被检测构件移动触碰成像设备的传动机构。
在其它一些实施方式中,根据成像设备的类型,转动体61f的旋转轴线L3与联接件21f的旋转轴线L1可以呈不同的夹角(例如90度,60度或30度等等),此种结构对精度的要求大大降低,提高了设计的灵活性。
在其它一些实施方式中,根据成像设备的类型,转动体61f可以设置在显影盒的不同位置,例如设置在第一侧,盒体1f的上方侧、下方侧或者后方侧,大大提高设计的灵活性。
在其它的一些实施方式中,显影盒还设置有传动断开机构(离合机构),传动断开机构用于切断第一传动体向被检测构件传递的驱动力,使得被检测构件停止移动。具体的对于第一传动体与柔性带通过摩擦传动的结构,传动断开机构可以是包括设置在柔性带内侧的光滑面,当该光滑面移动至与第一传动体31f接触的位置时,第一传动体31f无法向柔性带传递驱动力,柔性带停止转动。
在其它的一些实施方式中,可以根据设计需要将上述变形方式进行组合。
具有上述结构的显影盒,通过柔性传动件进行驱动力的传递,被检测构件的设置位置将可以多样化,转动体的旋转轴线L3可以与联接件21f的旋转轴线L1呈一角度,也即可以不需要平行设置,角度可以根据需要进行调整;成像设备的检测单元设置的灵活性也提高。具有上述结构的显影盒10f,采用柔性传动件4f有效地解决了长距离传动所出现的速度差问题。
具有上述结构的显影盒10f,与直接通过齿轮与转动体61f进行驱动力的传递相比,齿轮的直接传递需要严格考虑传动比,当需要控制转动体61f的旋转速度时,需要通过多个齿轮进行减速,增加了零部件,增加生产成本。转动体61f和第一传动体31f通过柔性传动件4f连接,当需要降低传递的速度时,只需要调节转动体61f和第一传动体31f的直径即可,大大降低设计成本。
具有上述结构的显影盒10f,当需要要求多次触碰成像设备的传动机构时,可以在柔性传递件上或转动体61f上设置多个被检测构件6f或增加转动的圈数即可;当要求每次触碰的间隔需要更长时,此种结构的设置也是有利的。
实施例7
如图23和图24所示,本实施例的显影盒与实施例6的显影盒的形状结构基本相同,其相同之处不在赘述,以下介绍其不同之处。
本实施例的柔性传动件为柔性绳4f1,柔性绳4f1一端缠绕或连接在第一传动体31f上,另一端缠绕在转动体61f上,可以通过控制转动体61f上缠绕的柔性绳4f1的圈数来控制转动体61f的旋转圈数。柔性绳4f1在第一传动体31f和转动体61f上缠绕的方向相反。
当显影盒10f安装至成像设备,联接件21f接收驱动力旋转时,第一传动体31f接收驱动力旋转并牵拉柔性绳4f1,由于柔性绳4f1的牵拉,转动体61f开始旋转进而使设置在转动体61f上的被检测构件6f与成像设备的传动机构触碰。在这种结构中,随着第一传动体31f和转动体61f的旋转,第一传动体31f缠绕的圈数增加,转动体61f缠绕的圈数减少。
在其它的一些实施方式中,在第一传动体31f和转动体61f之间还可以设置方向转变体,以改变传动的方向。具体的,该方向转变体可以是滚轮,柔性绳4f1绕过滚轮以改变传动方向,再与转动体61f连接。可选择的,方向转换体还可以是一个固定的第二支撑件,第二支撑件作为支点,柔性绳4f1绕过该支点而改变方向。
在其它的一些实施方式中,柔性传动件还可以是钢丝、铁丝等金属丝或者是链条。
在其它的一些实施方式中,显影盒还设置有传动断开机构(离合机构),传动断开机构用于切断驱动力接收单元向被检测构件传递的驱动力,使得被检测构件停止移动。在本实施例中,柔性绳或钢丝可以不绑定在转动体61f上,其结果是随着转动体61f的旋转,最终柔性绳从转动体61f脱落,转动体停止旋转,被检测构件停止转动。
实施例7中,显影盒的其他结构及变形方式可以参阅实施例6的描述,不再赘述。
实施例8
本实施例是在实施例1及其变形例的基础上作改进,实施例8的显影盒的形状结构与实施例1的显影盒的形状结构基本相同,相同部分不再赘述,以下主要介绍其不同之处。

在本实施例中,作用部具有两个,分别为形状和结构相同的第一作用部33g和第二作用部34g。
以第一作用部33g为例,第一作用部33g沿槽轮构件3g的旋转轴线方向向远离第一侧壁的方向延伸,以能够在槽轮构件3g旋转时推动传动件4g的受力部41g。
接下来结合图25介绍显影盒被成像设备的检测单元检测的动作过程。
在本实施例中,显影盒未被使用时,传动件4g的受力部41g与引导槽311g的侧壁312g抵接,被检测构件6g处于与检测单元分离的状态。
当槽轮构件3g接收驱动力旋转时,受力部41g在第一作用部33g的推动下,首先从第一作用部33g的根部向第一作用部33g的顶部移动,之后从第一作用部33g的顶部向第一作用部33g的根部移动,其结果是传动件4g向左侧滑动后向右滑动,同步的,被检测构件6g在传动件4g的带动下转动并触碰成像设备的检测单元后返回初始位置,随着槽轮构件3g的转动,第二作用部34g推动受力部41g并重复第一作用部33g与受力部41g之间的配合动作过程,被检测构件6g能够再次触碰检测单元,最终完成检测。
具有上述结构的显影盒,其还能够省略弹性件的设置,传动件依赖引导槽防止受力部脱离槽轮构件3g。
实施例9
本实施例是在实施例4及其变形例的基础上作改进,实施例9的显影盒的形状结构与实施例4的显影盒的形状结构基本相同,相同部分不再赘述,以下主要介绍其不同之处。

在本实施例中,作用部具有两个,分别为形状和结构相同的第一作用部33h和第二作用部34h。以第一作用部33h为例,第一作用部33h沿主体部31h的径向方向延伸,以能够在槽轮构件3h旋转时推动传动件4h的受力部41h。
传动件4h能够绕位于中部的轴部46h上下摆动,其包括杆部42h和受力部41h,杆部42h远离槽轮构件3h的一端与被检测构件6h固定连接。
接下来结合图26和图27介绍显影盒被成像设备的检测单元检测的动作过程。
在本实施例中,显影盒未被使用时,传动件4h处于第二位置,在该位置,受力部41h位于第一作用部33h的顶部,被检测构件6h处于未触碰检测单元的状态。
当槽轮构件3h接收驱动力旋转时,受力部41h从第一作用部33h的顶部向第一作用部33h的根部移动,杆部42h的第一端向下移动,杆部的第二端向上抬升并带动被检测构件6h向上移动,被检测构件6h触发成像设备的检测的单元。
在第二作用部34h推动传动件4h的受力部41h的过程中,受力部41h先向上移动后向下移动,同步的,被检测构件6h向下移动脱离检测单元后向上移动再次触碰检测单元,进而实现检测。
具有上述结构的显影盒,其能够省略弹性件的设置,传动件依赖引导槽的限制作用限制其脱离槽轮构件3h。
可选择的,作用部的数量和形状结构可以根据需要进行改变;例如设置一个或多个作用部;多个作用部的形状结构不同等。
实施例10
本实施例是在实施例1及其变形例的基础上作改进,实施例10的显影盒10j的形状结构与实施例1的显影盒10a的形状结构基本相同,相同部分不再赘述,以下主要介绍其不同之处。
如图28至图34所示,本实施例的驱动构件配置为凸轮构件,显影盒10j设置有离合机构,用于在预设的时间切断向被检测构件6j传递驱动力。离合机构包括迫推结构和退缩结构,迫推结构用于迫使凸轮构件3j的至少一部分移动,退缩结构使得该至少一部分的移动具有位移空间。具体的,退缩结构包括设置在凸轮构件3j靠近第一侧壁11j一端的第一突起部81j以及位于支撑件87j上的避让部82j,具体的该避让部为开口82j。
第一突起部81j可以抵压在支撑件87j的表面上移动,当第一突起部81j移动至开口82j处时,在迫推结构的作用下第一突起部81j掉入开口82j中,实现凸轮构件3j移动。
支撑件87j与第一侧壁固定连接或者替代第一侧壁。迫推结构包括设置在第一端盖101j上的第二突起部83j和设置在凸轮构件3j远离第一侧壁11j一端上的第三突起部85j,第二突起部83j和第三突起部85j的突出方向相反,在凸轮构件3j旋转时,第三突起部85j能够沿着第二突起部83j的迫压面移动至第二突起部83j的顶部,以迫使凸轮构件3j沿着显影盒10j的长度方向移动,以断开驱动力的传递。
迫推结构和退缩结构的相互配合关系为,在第二突起部83j迫推第三突起部85j前,第一突起部81j率先移动至开口82j处。或者在第二突起部83j迫推第三突起部85j时,第一突起部81j同时移动至开口82j处。具有此种结构的显影盒10j,可以省略弹性件的设置,结构更为简单,装配更为方便。
本实施例的凸轮构件3j还包括主体部31j、凸轮部33j以及旋转力接收部313j,主体部31j大致呈圆柱状,其圆周外侧设置有凸缘部311j。第三突起部85j从凸轮构件3j远离第一侧壁11j的一侧向外突出,能够抵接在第一端盖101j的内侧面。第一突起部81j从主体部31j向靠近第一侧壁11j的方向突出。凸轮部33j设置在凸缘部311j靠近第一侧壁11j的一侧面,朝向第一侧壁11j的方向突出,以能够与传动件4j形成配合。旋转力接收部313j能够从主体部31j的圆周外侧沿着主体部31j的径向方向突出,以接收驱动力。第二齿轮部件32j包括中空部321j、齿轮部322j和旋转力传递部323j,中空部321j呈圆柱中空,其能够套设在凸轮构件3j的外侧。
旋转力传递部323j从中空部321j的内壁沿第二齿轮部件32j的径向方向突出,并能够与凸轮构件3j的旋转力接收部313j接合,当第二齿轮部件32j旋转时,旋转力传递部323j带动旋转力接收部313j旋转,当凸轮构件3j沿着显影盒10j的长度方向移动时,旋转力传递部323j与旋转力接收部313j能够在显影盒的长度方向上脱离接合,中断旋转驱动力的传递。
在本实施例中,显影盒还设置有限制第二齿轮部件32j移动的限制部,具体的该限制部为设置在第一侧壁11j上的突起116j,突起116j抵接在第二齿轮部件32j靠近第一侧壁11j的一端,能够限制凸轮构件3j与第二齿轮部件32j发生相对移动时第二凸轮部件32j随凸轮构件3j移动,使得旋转力传递部323j与旋转力接收部313j二者之间能够较好地分离。优选的,限制部可以设置多个,限制部除了设置在侧壁上还可以设置在端盖上。
盒体1j上侧设置有滑槽部16j,传动件4j可滑动的容纳在滑槽部16j中,具体的传动件4j的上表面与盒体1j的上表面齐平或低于盒体1j的上表面。
显影盒10j还设置有至少部分覆盖传动件4j的覆盖部7j,本实施例的覆盖部7j呈长条状,其能够卡接在盒体1j上,以覆盖传动件4j。
具体的,覆盖部7j的两端设置有卡接部71j、第一暴露部72j和第二暴露部73j。位于两端的卡接部71j卡接在盒体1j上以固定覆盖部7j,第一暴露部72j和第二暴露部73j配置为开口,传动件4j的一端可以从第一暴露部72j伸出并与凸轮构件3j配合。被检测构件6j的被检测部63j从第二暴露部73j暴露,以能够与成像设备的检测单元配合。
被检测构件6j以能够沿上下方向摆动的方式支撑在覆盖部7j的第二端,覆盖部7j的第二端配置有容纳腔75j,以容纳部分被检测构件6j。
具体的,被检测构件6j的连接部62j以转轴的方式与覆盖部7j摆动连接,连接部62j的摆动轴位于力接收部61j的上方侧,被检测部63j设置在摆动轴的下方侧且在安装至成像设备的状态下位于检测单元的传动机构200j的下方侧,被检测部63j上下摆动时能够触发传动机构200j。
在本实施例中,传动件4j的第二端还包括折弯段46j,该折弯段46j向下弯折并连接驱动部47j,传动件4j的驱动部47j沿着显影盒10j的长度方向延伸。被检测构件6j可摆动地支撑在覆盖部7j上,力接收部61j位于连接部62j摆动轴的下方侧,当传动件4j的驱动部47j触发被检测构件6j的力接收部61j时,被检测构件6j摆动,被检测部63j向上抬升触发检测单元,以能够被检测。
在本实施例中,当显影盒10j安装至成像设备的状态下,被检测构件6j的被检测部63j受到传动机构200j(传动机构具有弹性力)的抵压,被检测构件6j的力接收部61j往右侧推压传动件4j以使得传动件4j牢牢抵压在凸轮构件3j的凸缘部311j上。
当凸轮构件3j的凸轮部33j推动传动件4j时,传动件4j往显影盒10j的右侧移动,进而推动被检测构件6j转动,被检测构件6j的被检测部63j向上移动抵压检测单元的传动机构200j转动,进而能够被检测。
当传动件4j的受力部41j从凸轮部33j的顶部向根部移动时,在传动机构200j的迫压力的作用下,被检测构件6j推动传动件4j向显影盒10j的左侧移动。
接下来结合图35a至图35c介绍显影盒10j被成像设备检测的过程中各部件的配合关系图。
如图35a所示,在显影盒10j安装至成像设备的状态下,被检测构件6j的被检测部63j受到传动机构200j的迫压,传动件4j抵压在凸轮构件3j上,第三突起部85j抵在第一端盖101j的内壁上,第一突起部81j抵在支撑件87j的上。
如图35b所示,当凸轮部33j推动传动件4j时,传动件4j推动被检测构件6j,被检测构件6j的被检测部63j向上摆动并推动传动机构200j,从而实现被检测。
如图35c所示,随着凸轮构件3j的旋转,凸轮部33j脱离传动件4j时,传动机构200j弹性恢复压迫被检测部63j向下恢复至初始位置。
当第二突起部83j迫压第三突起部85j时,第一突起部81j位于开口82j处,从而迫使凸轮构件3j向右侧移动,凸轮构件3j的旋转力接收部313j与第二齿轮部件32j的旋转力传递部323j断开连接,旋转力的传递中断,检测完成。
具有上述结构的显影盒10j,设置有滑槽部16j,传动件4j的滑动效果更佳,且可减少受外界的触碰和干扰。显影盒10j设置覆盖部7j,其能够有效的保护传动件4j、被检测构件6j免受外界的碰撞和干扰。此外,本实施例的显影盒10j可省略第二端盖,减少了零部件,降低生产成本。
本实施例的显影盒10j还包括碳粉填充口106j和填充盖107j,碳粉填充口位于显影盒的第二侧壁12j上,与粉仓连通。显影盒的第一端还可以设置芯片和芯片支架。
在一些实施方式中,第二突起部83j能够沿着第三突起部85j的迫压面移动至第三突起部85j的顶部,以迫使凸轮构件3j沿着显影盒10j的长度方向移动。
在一些实施方式中,第二齿轮部件32j与凸轮构件3j一体成型或固定连接,凸轮构件3j沿着显影盒10j的长度方向移动时,第二齿轮部件32j与驱动力接收单元的惰轮24j脱离啮合,从而实现中断驱动力的传递。
在一些实施方式中,第二突起部83j可以不设置在端盖上,而设置在与壳体固定连接的部件上。
在一些实施方式中,显影盒刚装入成像设备时,被检测部不与传动机构200j接触。
在一些实施方式中,显影盒设置弹性复位件,使得传动件不受凸轮部作用时恢复至初始位置。
在一些实施方式中,采用齿条结构替代凸轮构件,可以通过在齿条上设置驱动传动件的突起部,齿条通过齿部接收驱动力使得齿条移动,再通过突起部驱动传动件移动。
在一些实施方式中,迫推结构还可以是螺旋槽与凸起的配合结构,例如在端盖上设置沿显影盒的长度方向延伸的螺旋槽,凸轮构件上设置与螺旋槽配合的凸起,当凸轮构件旋转时,凸起沿着螺旋槽移动,进而实现在显影盒的长度方向移动。
实施例11
本实施例是在实施例10及其变形例的基础上作改进,实施例11的显影盒10m的形状结构与实施例10的显影盒10j的形状结构基本相同,相同部分不再赘述,以下主要介绍其不同之处。

传动件4m呈杆状,其一端抵接在凸轮构件3m的凸缘部311m上以能够被凸轮部33m驱动,另一端连接被检测构件6m以能够驱动被检测构件6m移动。
被检测构件6m以能够沿上下方向摆动的方式支撑在覆盖部的第二端,具体的,被检测构件6m的力接收部61m向上延伸并插入传动件4m第二端的开口或凹槽中,以在传动件4m左右移动时能够驱动被检测构件6m。
被检测构件6m的连接部62m以转轴的方式与覆盖部摆动连接,连接部62m的摆动轴位于力接收部61m的下方侧,被检测部63m设置在力接收部61m的下方侧且在安装至成像设备的状态下位于检测单元的传动机构200m的下方侧,被检测部63m上下摆动时能够触发传动机构200m。
在本实施例中,当显影盒10m安装至成像设备的状态下,被检测构件6m的被检测部63m受到传动机构200m的抵压,被检测构件6m的力接收部61m往右侧推压传动件4m以使得传动件4m牢牢抵压在凸轮构件3m上。
接下来结合图38a至图38c描述显影盒被成像设备检测的过程各部件的配合动作。
如图38a所示,在显影盒10m安装至成像设备的状态下,被检测构件6m的被检测部63m受到传动机构200m的迫压,传动件4m抵压在凸轮构件3m的凸缘部311m。
如图38b所示,当凸轮构件3m的凸轮部33m推动传动件4m的受力部41m时,传动件4m往显影盒10m的左侧移动,进而带动被检测构件6m的力接收部61m转动,被检测构件6m的被检测部63m向上移动抵压检测单元的传动机构200m转动,进而能够被检测。
如图38c所示,当传动件4m的受力部41m从凸轮部33m的顶部向根部移动时,在传动机构200m的迫压力的作用下,被检测构件6m带动传动件4m向显影盒10m的右侧移动。
当传动件4m的受力部41m移动至缺口部312m时,在传动机构200m的力的作用下,被检测构件6m带动传动件4m的受力部41m掉入缺口部312m中并向显影盒10m的右侧移动,凸轮构件3m继续旋转,受力部41m不再受到凸轮部33m的驱动,力的传递中断。
具有上述结构的显影盒,离合机构简单,制造成本低。

本申请的各个实施例及其变形方式中,被检测构件的移动方向也可以根据需要进行简单变动,被检测构件设置的位置也可以灵活设计,大大提高了显影盒设计的灵活度;同时通过调整被检测构件位置的设置,有利于显影盒的小型化。
本申请的各个实施例及其变形方式中,被检测构件由传动件驱动,该传动件的至少一部分在盒体的长度方向上移动而驱动被检测构件,无需通过搅拌构件的旋转轴传递驱动被检测构件的作用力,不仅消除了搅拌构件的旋转轴容易产生变形甚至断裂的风险,而且解决了搅拌构件的旋转轴变形导致的驱动力传递延时的问题,提升了检测精度
最后应说明的是:除非存在相互矛盾或排斥的情形,否则以上所公开的不同实施例及其变形方式可以相互引用、参照或组合,不同实施例及其变形方式的技术特征也可以进行相互的组合和/或替换。
以上实施例仅用以说明本发明公开的技术方案,而非对其限制,为了便于区分不同的部件,本发明公开引入了“第一”、“第二”等术语,其中术语“第一”、“第二”等术语不是理解为对其数量上的限制,例如本发明公开公开中记载的驱动构件具有第二齿轮部,但并不意味着驱动构件一定具有第一齿轮部和第三齿轮部等。
根据说明书的记载,“第一”、“第二”等说明的部件可以是一个,也可以是包含多个;术语中的“上方”“上侧”“下方”“下侧”是基于附图中的说明,并非对其方位的特定限制。尽管参照前述各实施例对本发明公开进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分或者全部技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本发明公开各实施例技术方案的范围。
