具体实施方式
为使本实用新型实施例的目的、技术方案和优点更加清楚，下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
图1是本实用新型提供的成像设备结构示意图，图2是本实用新型提供的处理盒的结构示意图，图3是本实用新型提供的芯片的主视图。参见图1至图3，成像设备1包括主体2，送纸装置(未示出)，激光扫描装置，感光装置、处理盒10，转印装置、定影装置和排纸装置。
主体2构成成像设备1的外表，并支撑安装在其中的各种部件。主体盖3旋转地安装在主体2的一侧上，以打开和关闭主体2的一部分。用户可通过主体盖3接近主体2的内部，以更换或者维修包括处理盒10K、10C、10M和10Y的各种部件。
主体盖3相对于箭头方向A设置在处理盒10K、10C、10M和10Y的后部，以将处理盒10K、10C、10M和10Y安装在主体10上。在主体盖3的内表面上，形成压迫构件4，以通过压迫处理盒10K、10C、10M和10Y而防止处理盒10K、10C、10M和10Y运动。更具体地讲，压迫构件4从主体盖3的内表面突出，以当主体盖3处于封闭状态下时压迫每个处理盒的后端101的两侧。这里，压迫构件4可具有预定的弹性以压迫各个处理盒10K、10C、10M和10Y。
处理盒10K、10C、10M和10Y结构基本相同，在此仅描述处理盒10K的基本构成，处理盒10K包括盒体11、把手12、和显影辊13。设置在盒体11内的充电单元(图上未示出)、盒体11包括前端和后端，显影辊13设置在盒体11的前端，把手 12设计在盒体的后端，显影辊13的一端设置有驱动力接收部件15用于接收来自成像设备1的驱动力，显影辊13另一端附近设置有电源接收单元14。处理盒1的后端还设置有凹陷部16，用于安装芯片20。
实施例一
如图4所示，芯片20包括存储单元、控制单元和输入输出接口(通信端子)。在带有芯片20的处理盒安装到成像设备1时，芯片20与成像设备1之间通过输入输出接通信，对存储单元进行读写操作。
成像设备1的主体盖3上设置有接触点5，接触点5用于与芯片20的输入输出接口连接。
如图3所示，本实用新型提供的芯片20，优选地输入输出接口可以设置为包括有2个端子，第一端子21和第二端子22。其中至少一个为多用途端子。多用途端子设置为电源和信号沟通用，电源和信用可同时共用与双向沟通，另外一个端子可设置为接地端子或多用途端子。
多用途端子实现的原理可以通过1-wire、I2C、SCI或UART来实现，在此不再赘述。
本实用新型提供的端子的数目还可以是2-6个(21-26)，其中至少一个端子为多用途端子，还可以单独设置接地端子和电源端子。设置4个以上端子是基于兼容不同成像设备使用，因为成像设备上的触点排列间隙不一，在设置4个以上端子的芯片上，其未与触点接触的端子允许浮接，不影响芯片的使用。
如设置有6个端子的芯片20，其6个端子可以分别为，第一端子21可以设定为接地端子或多用途端子；第二端子22可以设定为电源和信用双用端子；第三端子23、第四端子24和第五端子25可以设定为多用途端子，可根据用途自由定义信号组态，第六端子26可设定为电源端子。
更具体地，芯片20的详细结构可以参加图6和图7，芯片20包括端子部分220和控制部分210，具体地端子部分220为使用时芯片20的正面(如图3所示面)，而控制部分210为芯片的反面。其中，控制部分210包括型号识别单元211、区域识别单元212，控制单元213和存储单元214。端子部分220包括回路切换模块221和端子222。
具体地，回路切换模块221连接端子222和控制部分220。回路切换模块221包括电源供应回路223、信号传输回路224和接地回路225。
型号识别单元211可识别与芯片20连接的成像设备1的开号，区域识别单元212 可识别则可识别成像设备1使用的区域。诚然，这两个识别单元可以合二为一个识别单元，在此仅是优选地分为两个识别单元。
存储单元214存储有处理盒的相关信息，还可供成像设备1读写操作，如读取所存储的信息，及写入已经打印的页数，及使用的碳粉量，剩余碳粉量等，还存储有对应使用区域的信息，以及多个序列号，多个序列号供复位时使用，复位操作将在下文详细描述。
本实用新型的目的在于提供至少一个多用途端子，也就是各个回路连接有复数个端子，至少一个端子连接有复数个回路。
其中，在仅需要2个端子的芯片20中，第一端子21为多用途端子，第一端子21分别通过切换开关21A/21B与信号传输电路224和接地回路225连接。第二端子22也可以为多用途端子，第二端子22分别通过切换开关22A/22B连接电源供应回路223和信号传输回路224。
第三端子23，和第四端子24分别通过切换开关23A和24A连接信号传输回路224，第五端子25通过切换开关25A连接电源供应回路223。
上述仅是连接方式，仅是对其中一种连接方式的解释，具体使用中，各端子与各回路的连接方式可以通过设置多个切换开关来实现多种连接。在使用时，控制单元通过型号识别单元来识别成像设备的型号来控制回路切换模块，切换多个切换开关，使多个端子实现不同的功能，完成与成像设备的通信。
本实用新型提供芯片，随处理盒一起安装至成像设备时，是通过如下方法实现匹配使用的。
步骤一：将带有本实用新型提供芯片的处理盒安装到成像设备，开机；
步骤二：芯片的识别单元通过端子与成像设备的连接识别成像设备的型号；
步骤三：控制单元控制回路切换模块切换端子与回路模块的连接方式，并锁定此连接方式。锁定连接方式的好处在于，下次开机时不再需要重新识别匹配使用。
本实施例提供的芯片，通过设置有2个以上的端子，其中至少一个为用途端子，以实现在不同成像设备之间芯片的通用。
实施例二
图5所示，本实施例提供的芯片与实施例一不同之处在于，增加了一个复位单元。复位单元用于重置成像设备给芯片写入的已经使用的碳粉量和剩余的碳粉量。通常成像设备计算处理盒的碳粉剩余量是以5％覆盖率/页来计算。
本实施例提供的复位单元，在用户重新添加碳粉之后，可执行复位操作，使得处 理盒能够重复使用，以节约用户的成本。
本实施例提供的复位单元，可以是设置在芯片中的的一个挡路端子，用户在添加好碳粉之后，通过触碰此开关，在处理盒安装到成像设备之后，主控制单元会自动更换信息，如序列号，在成像设备读取芯片信息时，会得到此处理盒的碳粉容量是满的，重新开始计数。
图8所示为本实用新型芯片切换使用区域的方法流程图，通常OEM生产的成像设备会按销售区域分不同的型号，对应地处理盒芯片也分不同型号，但是也会出现销往中东地区的成像设备发到了欧美市场。另外，用户要通过打印自检页才能得知自己成像设备的型号。
本实用新型提供的芯片，可以切换使用区域，具体流程如下：
步骤S01：将全新处理盒安装到成像设备当中，开机；
步骤S02：成像设备从芯片中读取数据；
S03：基于读取的数据确定是否与打印机初始设定的使用区域匹配，否则返回步骤S02，是则进入步骤S04；
S04：确定芯片与打印使用区域匹配后，锁定芯片的区域。
进一步地，步骤S02还包括给芯片先断电再重新上电操作，或无需重新上电操作，主控制单元自动切换使用区域供成像设备读取。
优选地，本实用新型提供的芯片，在出厂时按销售区域将区域信息优先匹配排队，以减少需要切换使用区域信息的操作。
图9是本实用新型提供的芯片重复利用的流程图，如图9所示，本实用新型提供的芯片，包括以下步骤：
步骤S1：将成像设备开机，成像设备对处理盒芯片进行读写操作，读取处理盒的碳粉剩余量；
步骤S2：检测剩余碳粉量是否小于预设值，预设值为5％-15％，如果否则重新进行步骤S2，是则进入步骤S3；
步骤S3：提醒用户碳粉量不足，请添加碳粉；
步骤S5：用户添加碳粉后，执行复位操作，将芯片中碳粉剩余量恢复至初始值。
步骤S5中的复位操作，可以是上文提到的在芯片中设置复位单元，通过拨动类似于微型开头来执行复位操作，也可以是通过小的烧录工具进行恢复，也可以是在碳粉耗尽之后，设置为预定操作之后自动恢复。
本实用新型提供的芯片，处理盒及成像设备，解决了现有技术中不同成像设备需 要不同芯片的问题。
最后应说明的是：以上实施例仅用以说明本实用新型的技术方案，而非对其限制；尽管参照前述实施例对本实用新型进行了详细的说明，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实用新型各实施例技术方案的精神和范围。
