Description

一种成像盒
本申请要求享有2014年12月10日提交的名称为“一种成像盒”的中国专利申请为CN201420777872.4的优先权，其全部内容通过引用并入本文中。
技术领域
本实用新型涉及打印成像技术，尤其是一种适配于成像装置的固有检测需求的成像盒。
背景技术
成像装置，例如打印机、复印机、传真机等，用于将要成像的信息通过碳粉等成像材料成像到纸张等成像介质上。成像装置通常包括成像装置主体和可拆卸地安装到成像装置主体上的成像盒。成像盒通常设置有用于容纳碳粉等成像材料的粉仓以及用于存储成像盒相关信息的耗材芯片。耗材芯片通常也以可拆卸的方式安装在成像盒上。
现有技术中，为检测成像盒粉仓内的碳粉的实际余量，在成像盒上通常还设置有编码轮，在成像装置主体上还设置有红外光检测装置。由编码轮和红外光检测装置共同构成编码轮光检系统。
图1是现有技术中的一个编码轮光检系统的组成结构示意图。具体地，成像装置1的主体带有成像装置控制模块101，主体一侧设置有与成像装置控制模块101电性连接的装置侧发光元件102和装置侧受光元件103。这两个元件在竖直方向上邻近，并且分别在成像装置控制模块101的控制下发射红外光和接收红外光。成像盒2包括用于容纳碳粉的粉仓201。在粉仓201的外端部设置有编码轮202，其通过扭力轴与粉仓201内的搅拌架同轴连接。该编码轮202上还设置有用于反射光线的大反光镜203和小反光镜204。具体地，这两个反光镜分布于扭力轴的两侧，并且两个反光镜的中心与扭力轴的端部共线设置。当成像盒2安装到成像装置1上后，编码轮202的设有两个反光镜的一面朝向成像装置1的装置侧发光元件102和装置侧受光元件103。而且，装置侧发光元件102和装置侧受 光元件103构成的竖直面正对编码轮202的位于扭力轴一侧的部分，而不与另一侧正对，同时装置侧发光元件102和装置侧受光元件103在竖直方向上相对于扭力轴对称设置。这种结构使得只有当编码轮202上的反光镜随着粉仓201内搅拌架的转动而转至正对装置侧发光元件102和装置侧受光元件103的位置时，才能将装置侧发光元件102发射的红外光反射到装置侧受光元件103上。当成像装置1驱动粉仓201内的搅拌架转动来搅拌碳粉时，由于碳粉的阻力传递至扭力轴，使得编码轮202的转动速度时快时慢。具体现象为，当成像装置控制模块101控制装置侧发光元件102发出红外光时，从大反光镜203反射光到小反光镜204反射光的时间间隔，与从小反光镜204反射光到大反光镜203反射光的时间间隔不相等，且这两个时间间隔与粉仓201内的碳粉余量有关。因此，现有技术可以通过分析装置侧受光元件103所接收的红外光信号的时间间隔来推算粉仓201内碳粉的实际余量。
由上可知，在成像盒上设置编码轮光检系统，需要采用特定材料的扭力轴以满足成像装置的检测需求。而且，检测结果的精度与编码轮反光镜的反光特性和位置设置有关。一旦反光镜表面清洁度低或位置设置存在误差，就会导致成像装置无法检测到反射回来的红外光信号，进而给出成像盒适配出错的误报信息，给用户的使用造成不便。此外，为了满足某些成像装置检测到特定波形的红外光信号的固有检测需求，生产厂商还需要投入额外的人力物力对编码轮光检系统的具体设置进行适应性调整，这也会增加生产成本。这里所说的固有检测需求是指成像装置至少能够通过接收某一特定波形的红外反射光而识别到成像盒的基本要求。

具体实施方式
本领域普通技术人员应理解，为了简化描述过程以及使技术方案清楚呈现，以下仅以激光打印机、碳粉盒和编码轮光检结构为例，下述实施例的方案描述同样适用于其他类型的成像装置、成像盒和可行的光检结构。
在现有的成像盒中，通常还配置有用于存储成像盒相关信息的耗材芯片3，该耗材芯片以可拆卸的方式安装在成像盒上。如图2所示，一个耗材芯片3上通常设置有电源端子301和接地端子302，用于与成像装置侧的端子建立电性连接，分别接收成像装置供给的电源电压VCC和接地电压GND，从而为读写控制模块303和存储单元304供电。读写控制模块303用于将成像装置通过其它数据端子发送来的数据写入存储单元304，或者，将存储单元304中存储的数据读出进而发送给成像装置；存储单元304用于存储碳粉的余量或消耗量等数据信息，以及其它与成像盒相关的信息，如碳粉的颜色信息等。
需要说明的是，下述本实用新型的各实施例及附图中将耗材芯片、成像盒以 及成像装置的结构进行了适当省略，与本实用新型的方案不相关的结构不予描述。但是，本领域普通技术人员应当理解，下述各实施例中所提及的耗材芯片仍然可以包括电源端子、接地端子以外的读写控制模块、存储单元和其它数据端子。
图3为本实用新型实施例中成像盒上的发光模组的组成示意图。该发光模组4包括供电模块401、控制模块402和发光元件403。
供电模块401用于为控制模块402提供工作所需的电能。它可以是与成像装置侧端子相接触的供电端子，从成像装置获取电能；或者是与成像盒的耗材芯片的供电电路相接触，间接地从成像装置所供给的电能上取电；或者是单独的电池，例如不可充电的干电池、可重复充放电的蓄电池；又或者，还可以是由电容、电感等元件构成的储能电路。总而言之，只要能够为控制模块402供电即可。
当供电模块401提供电能时，控制模块402控制发光元件403持续地发出特定频率的光。通常，依据设定的电路，只要供电模块401开始供电，控制模块402就开始控制发光元件403持续地发出特定频率的光。该特定频率的光为适配于成像装置的固有检测需求的光信号，并且能够表征成像盒内成像材料的余量。上述成像材料的余量既可以为成像材料的实时余量，如粉仓内的碳粉余量；也可以为所计算的当前的成像材料的余量，如成像装置所估算的碳粉余量；也可以为成像材料的某一特定的余量，如碳粉余量保持为满粉量。换言之，上述光信号所表征的成像材料的余量可以为实际或计算的可变值，也可以为特定的固定值。优选地，控制模块402控制发光元件403持续地发出表征碳粉余量为满粉量的光，以使成像装置始终能够识别成像盒。
在控制模块402的控制下，发光元件403能够持续发出适配于成像装置的光信号。具体地，发出的光线可以是可见光，也可以是不可见光，例如红外光、紫外光等。发出的光线是基于成像装置所要检测的光的类型而设置，或者根据成像装置可检测的适配于成像装置的固有检测需求的光的类型而设置。
在本实用新型中，上述发光模组被安装到成像盒上，以代替现有技术中的编码轮结构，从而以简单的结构和较高的可靠性完成与成像装置适配，满足成像装置对成像盒的固有检测需求。
下面，结合发光模组的几种可行的优选实现方式对本实用新型实施例所提供的成像盒的功能结构做详细描述。
实施例一
图4为本实用新型实施例一所提供的成像盒适配于成像装置的结构示意图。当成像盒2安装至成像装置1上时，耗材芯片3的电源端子301和接地端子302分别通过成像装置侧的端子与成像装置1的成像装置控制模块101建立电性连接，接收成像装置1的成像装置控制模块101所供给的电源电压VCC和接地电压GND。耗材芯片3用于与成像装置1的成像装置控制模块101进行数据通信，执行成像盒相关信息的存储与读取操作。
发光模组4的供电模块401是从耗材芯片3的电源端子301和接地端子302引出的导线，通过从成像装置1向耗材芯片3所供给的电源电压VCC和接地电压GND上取电，获取控制模块402工作所需的电能。当成像盒2安装至成像装置1时，成像装置1的成像装置控制模块101向耗材芯片3的电源端子301和接地端子302供电，发光模组4就获得了工作所需的电能。控制模块402控制发光元件403持续发出适配于成像装置的表征碳粉余量为满粉量的光。成像装置1的装置侧受光元件103接收到上述光信号，并将其转为相应的电信号后传给成像装置控制模块101进行处理，完成成像装置1对成像盒2的识别检测工作。
其中，发光模组4可以以可拆卸地方式安装至成像盒，也可以以不可拆卸地方式安装至成像盒，此处不予限制。
需要说明的是，在本实施例中，耗材芯片和发光模组可以是集成到同一块基片上的不同部件，又或者是功能电路完全集成到同一芯片内。总之，将发光模组以简单的发光装置或发光电路的形式实现，都能够实现本实用新型之目的。
同样的，针对没有设置耗材芯片但具有编码轮等复杂光检结构的成像盒，也可以设置本实施例中描述的发光模组。由发光模组向成像装置的装置侧受光元件发光，以解决成像盒的适配问题。
本实施例所提供的成像盒，在安装至成像装置时，从成像装置供给成像盒的耗材芯片的电源电压和接地电压上取电，并控制发光元件发出适配于成像装置的表征碳粉余量为满粉量的光，从而在成像装置对成像盒进行检测时能够接收到满足检测需求的光信号，使成像盒满足了成像装置的固有检测需求。此外，本实施例所提供的成像盒仅需一个发光模组，结构简单、制造成本低，并通过直接向成像装置的装置侧受光元件发光的方式，避免了现有技术中编码轮在反光过程中可 能引发的误差，提高了成像盒被成像装置识别的可靠性。
实施例二
图5为本实用新型实施例二所提供的成像盒适配于成像装置的结构示意图。相比于实施例一，本实施例所提供的成像盒仅在发光模组的控制模块的具体设置上存在不同。
如图5所示，本实施例所提供的成像盒2仍然包括耗材芯片3和发光模组4。其中，发光模组4的控制模块402设置在耗材芯片3内，直接由耗材芯片3的电源端子301和接地端子302供电(也即电源端子301和接地端子302作为供电模块401向控制模块402供电)，发光元件403独立于耗材芯片3而设置。当成像盒2安装至成像装置1时，成像装置1向耗材芯片3的电源端子301和接地端子302供电，控制模块402开始控制发光模组4的发光元件403持续发出适配于成像装置的表征碳粉余量为满粉量的光。成像装置1的装置侧受光元件103接收到上述光信号，并将其转为相应的电信号后传给成像装置控制模块101进行处理，完成成像装置1对成像盒2的识别检测工作。
需要说明的是，本实施例所提供的成像盒，控制模块设置在耗材芯片内，但是独立于耗材芯片的读写控制模块，单独地从电源端子和接地端子取电，来控制发光模组的发光元件发光，其所完成的功能与读写控制模块的数据读写相互独立且互不干扰。
本实施例所提供的成像盒，可以在现有的耗材芯片内划分一个功能电路作为控制发光元件发光的控制模块，只需再设置额外的发光元件即可满足成像装置的固有检测需求，使得成像盒的制造成本更低。
实施例三
图6为本实用新型实施例三所提供的成像盒适配于成像装置的结构示意图。相比于实施例二，本实施例所提供的成像盒的发光模组增设了余量信息获取模块。而且，该余量信息获取模块与控制模块一起优选地设置在耗材芯片3内。
如图6所示，本实施例所提供的成像盒2仍然包括耗材芯片3和发光模组4。其中，发光模组4的控制模块402、余量信息获取模块404设置在耗材芯片3内，控制模块402直接由耗材芯片3的电源端子301和接地端子302供电(也即电源 端子301和接地端子302作为供电模块401向控制模块402供电)，余量信息获取模块404能够依据控制模块402的控制，获取耗材芯片3的存储单元内所存储的粉量数据信息(即碳粉的余量数据信息)，或者从读写控制模块与成像装置通信的数据中获取粉量数据信息，并将当前的粉量数据信息传递给控制模块402。又或者，余量信息获取模块404是与成像装置1驱动粉仓201内的搅拌架转动的扭力轴连接的测量元件，通过测得与碳粉余量相关的扭力而获知当前粉量数据信息。控制模块402依据当前的粉量数据信息控制发光元件403发出适配于成像装置1的表征当前粉量的光。
需要说明的是，上述控制模块402和含量信息获取模块404也可以一个或全部独立于耗材芯片3而设置，只要能够从耗材芯片3上取电并获取成像材料当前的余量数据信息，即可实现本实用新型之目的。
本实施例所提供的成像盒，通过在耗材芯片内设置余量信息获取模块，经由控制模块的控制从耗材芯片的数据中获取当前成像材料的余量数据信息，然后由控制模块据此控制发光元件发出适配于成像装置的表征成像材料当前余量的光，就可以在满足成像装置的固有检测需求的基础上，更加准确地向成像装置反映当前成像材料的余量。
实施例四
图7为本实用新型实施例四所提供的成像盒适配于成像装置的结构示意图。相比于实施例一，本实施例所提供的成像盒的发光模组增设了检光元件。
如图7所示，本实施例所提供的成像盒2仍然包括耗材芯片3和发光模组4。其中，当成像盒2安装至成像装置1时，成像装置1向耗材芯片3的电源端子301和接地端子302供电，发光模组4的控制模块402通过从耗材芯片3的电源端子301和接地端子302取电(也即电源端子301和接地端子302作为供电模块401向控制模块402供电)来获取工作所需的电能。检光元件405与控制模块402电性连接，用于检测成像装置1的装置侧发光元件102是否发出检测光。当检光元件405检测到装置侧发光元件102发出检测光时，控制模块402控制发光元件403发出适配于成像装置1的表征碳粉余量为满粉量的光。成像装置1的装置侧受光元件103接收到发光元件403发出的光信号后，将其转成相应的电信号并传给成像装置控制模块101进行处理，完成成像装置1对成像盒2的识别检测工作。
需要说明的是，优选地，上述控制模块在检光元件检测到检测光时才控制发光元件开始发光，然后在经过设定的时间后自动的控制发光元件结束发光，当然也可以控制发光元件持续发光，并不结束。
本领域普通技术人员应当理解，上述检光元件可以是能够检测光的控制开关如光敏开关等，从而通过限制控制模块的供电或者限制控制模块与发光元件之间的电路通断而达到限制发光模组发光的目的。上述检光元件还可以是能够检测光的光敏元件，例如光敏三极管等，控制模块通过检测检光元件的电气特性，例如电压或电流的变化来获知成像装置的装置侧发光元件发出检测光。当然，绝不限于这两种实现方式。
本实施例所提供的成像盒，通过在发光模组内增设检光元件来检验成像装置是否发出检测光，并在检测到检测光时才控制发光元件发出适配于成像装置的表征碳粉余量为满粉量的光，从而可以避免发光元件在成像装置不对成像盒进行检测时仍然发光的情况，降低了成像盒的能量损耗，也能够延长发光元件的使用寿命。
可选的，发光模组还可以同时包括余量信息获取模块和检光元件，成像盒仍然包括耗材芯片和发光模组，发光模组的控制模块依据检光元件检测成像装置是否发出检测光，并在检测到检测光时，依据余量信息获取模块获取当前所述成像盒中成像材料的余量数据信息，控制发光元件发出适配于成像装置的固有检测需求的表征上述余量数据信息的光信号。
上述几个实施例仅仅对成像盒的功能结构做了详细描述，然而，在实际应用时，为了正确实现成像盒的光检功能，还需要顾及到光检装置的具体的安装结构。下面，结合上述成像盒和发光模组的几种可行的优选实现结构，对本实用新型实施例所提供的成像盒和发光模组的安装结构做详细描述。
实施例五
图8和图9为本实用新型实施例五所提供的发光模组的安装结构示意图。在这种实施方式下，发光模组4可以采用实施例一、二、三所述的发光模组。具体地，发光模组4设置于一块基板5上且发光元件403位于基板5的一侧。相应地， 成像盒2的粉仓201的外端部设置有插口(图8中未示出)。该插口位于穿过粉仓搅拌架的轴的水平面上，且至少能够容纳并固定住发光模组4所在的基板5的一端，使得当发光模组4安装至成像盒2时，基板5上的发光元件403位于成像盒2的插口的外部。当成像盒2安装至成像装置1时，基板5未插入插口的另一端邻近于成像装置1的装置侧发光元件102和装置侧受光元件103所在的竖直平面。同时，装置侧发光元件102位于基板5的一侧，装置侧受光元件103与发光元件403位于基板5的另一侧。这种结构使得基板5能够遮挡住装置侧发光元件102发出的光，装置侧受光元件103只能够接收发光元件403发出的光，从而避免出现光干扰现象。
同样的，在采用实施例四所述的包括检光元件的发光模组时，可以借助相同的基板结构进行安装。如图10所示，发光模组4设置于一块基板5上，发光元件403和检光元件405分别位于基板5的两侧。相应地，成像盒2的粉仓201的外端部设置有插口。该插口位于穿过粉仓搅拌架的轴的水平面上，且至少能够容纳并固定住发光模组4所在的基板5的一端，使得当发光模组4安装至成像盒2时，发光元件403和检光元件405位于成像盒2的插口的外部。当成像盒2安装至成像装置1时，基板5未插入插口的另一端邻近于成像装置1的装置侧发光元件102和装置侧受光元件103所在的竖直平面。同时，装置侧发光元件102与检光元件405位于基板5的同一侧，装置侧受光元件103与发光元件403位于基板5的另一侧。这种结构使得基板5能够遮挡住装置侧发光元件102发出的光，检光元件405只能够检测装置侧发光元件102发出的光，装置侧受光元件103只能够接收发光元件403发出的光，从而避免出现光干扰现象。
需要说明的是，本实施例采用上述安装结构，当发光模组安装至成像盒时，发光模组所在的基板插入成像盒的插口的距离，发光元件和检光元件相对于成像盒粉仓外端部的距离，以及发光模组所在的基板的长度等参数，可以参考相对应的成像盒和成像装置的光检系统的具体尺寸灵活设置。优选的，当成像盒安装至成像装置时，发光模组的发光元件位于装置侧受光元件接收最佳光信号的直线上，检光元件位于接收装置侧发光元件的最佳光信号的直线上。
本实施例通过将发光模组以插入的方式安装至成像盒，使发光模组的发光元件与成像装置的装置侧受光元件位于基板的一侧，发光模组的检光元件与成像装置的装置侧发光元件位于基板的另一侧，保证了发光模组的检光元件准确地检测 到光，以及发光元件准确地将光发送给装置侧受光元件。此外，通过使发光模组所在的基板处于成像装置的装置侧发光元件和装置侧受光元件之间，能够有效地降低光干扰，提高了识别的可靠性。
实施例六
图11为本实用新型实施例六所提供另一种发光模组的安装结构示意图。
如图11和图12所示，发光模组4可以采用实施例一、二、三所述的发光模组。此外还有一基板5和一挡板6。挡板6垂直于基板5设置，构成T字形结构。发光元件403设置于基板5上且位于挡板6的一侧。成像盒2的粉仓201的外端部设置有凹部。该凹部位于粉仓搅拌架的轴的一侧，可以容纳基板5装入其中。当发光模组4安装至成像盒2时，基板5上的发光元件403位于凹部的外部，同时挡板6位于穿过粉仓搅拌架的轴的水平面上。当成像盒2安装至成像装置1时，挡板6远离凹部的一端邻近于成像装置1的装置侧发光元件102和装置侧受光元件103所在的竖直平面。同时，装置侧发光元件102位于挡板6的一侧，装置侧受光元件103与发光元件403位于挡板6的另一侧。这种结构使得挡板6能够遮挡住装置侧发光元件102发出的光，装置侧受光元件103只能够接收发光元件403所发出的光，从而避免出现光干扰现象。
同样的，当发光模组4采用实施例四所述的包括检光元件的发光模组时，可以借助相同的T字形结构进行安装。如图13所示，挡板6垂直于基板5设置，构成T字形结构。发光元件403和检光元件405设置于基板5上且分别位于挡板6的两侧。成像盒2的粉仓201的外端部设置有凹部。该凹部位于粉仓搅拌架的轴的一侧，可以容纳基板5装入其中。当发光模组4安装至成像盒2时，基板5上的检光元件405和发光元件403位于凹部的外部，同时挡板6位于穿过粉仓搅拌架的轴的水平面上。当成像盒2安装至成像装置1时，挡板6远离凹部的一端邻近于成像装置1的装置侧发光元件102和装置侧受光元件103所在的竖直平面。同时，装置侧发光元件102与检光元件405位于挡板6的一侧，装置侧受光元件103与发光元件403位于挡板6的另一侧。这种结构使得挡板6能够遮挡住装置侧发光元件102发出的光，检光元件405只能够检测装置侧发光元件102发出的光，装置侧受光元件103只能够接收发光元件403发出的光，从而避免出现光干扰现象。
其中，基板5和挡板6可以通过定位孔与定位柱配合、凹口与凸起配合、螺母与螺钉配合、卡合以及粘贴等任意一种可拆卸的方式固定至成像盒2，也可以通过焊接等不可拆卸方式固定在成像盒2上。
需要说明的是，上述T字形结构中的挡板既可以与基板分离，分别安装至成像盒，也可以单独作为成像盒的不可拆卸的一部分，均能实现本实用新型之目的。
本实施例通过增加挡板，使得发光模组可以更加便利地装入成像盒的粉仓，同样可以有效地降低光干扰，提高了识别的可靠性。此外，发光模组无需长距离的凸出粉仓的外端部，可以有效降低发光模组被损坏的风险。
需要说明的是，本实施例五和六所提供的发光模组的安装结构，其中发光模组的基板或挡板的水平设置，是基于成像装置的装置侧发光元件和装置侧受光元件竖直设置的基础上做出的适配性设置。针对其它类型的成像装置，当装置侧发光元件和装置侧受光元件设置为其它方向时，如水平方向，相对应地，发光模组的基板或挡板设置为竖直方向。也即，保持发光模组的基板或挡板的两侧分别与装置侧发光元件和装置侧受光元件相对，即可实现遮挡光线的目的。
本领域普通技术人员应理解，以上本实用新型任意实施例所提供的成像盒的发光模组结构，不限于应用到本类型的编码轮的光检系统，同样适用于其它类型的光检系统。只要该光检系统具有发光元件和受光元件，均可采用本成像盒的发光模组结构来适配成像装置的固有检测需求。同样的，对于其他类型的成像装置的声音检测或电信号检测系统，通过将本成像盒的发光模组结构的发光元件设置为相应的发声单元或电信号产生单元，同样可以基于本实用新型的结构，适配成像装置的固有检测需求，其并不脱离本实用新型的保护范围。
显然，采用本实用新型的实施例所提供的成像盒，通过设置发光模组以及遮挡结构，在安装至成像装置时，从成像装置供给成像盒的耗材芯片的电源电压和接地电压上取电，并控制发光模组发出适配于成像装置的表征成像材料余量的光，从而在成像装置对成像盒进行检测时能够接收到满足检测需求的光信号，满足了成像装置的固有检测需求。相比于现有的编码轮光检系统，本实用新型的成像盒仅需一结构简单、成本较低的发光模组，向成像装置的装置侧受光元件发光，实现了成像装置对成像盒的固有检测，避免了现有技术中编码轮在反光过程中可 能引发的误差。而且，采用遮挡结构遮挡成像装置的装置侧发光元件所发的光，降低光干扰，提高了成像盒被成像装置识别的可靠性。
虽然本实用新型所披露的实施方式如上，但所述的内容只是为了便于理解本实用新型而采用的实施方式，并非用于限定本实用新型。任何本实用新型所属技术领域内的技术人员，在不脱离本实用新型所揭露的精神和范围的前提下，在实施的形式上及细节上所作的任何修改与变化，都应该在本实用新型的专利保护范围内。
