[0019] 通过复位扭簧和复位部的配合， 保证了每次处理盒安装至成像装置时， 驱动头 突起的位置保持不变， 提高了处理盒安装过程的顺畅性， 提高打印品质。 并且 ， 驱动力传递组件所构成的零部件数量少， 产品的结构简单， 工艺简单， 生产 成本低。 [0019] By resetting the cooperation of the torsion spring and the resetting portion, it is ensured that the position of the protrusion of the driving head remains unchanged each time the process cartridge is mounted to the image forming apparatus, the smoothness of the process of mounting the process cartridge is improved, and the printing quality is improved. Moreover, the number of components formed by the driving force transmission component is small, the structure of the product is simple, the process is simple, and the production cost is low.
[0020] 另外， 当复位部凸出端部的外壁设置时， 在处理盒安装到成像装置前， 复位扭 簧的第一扭臂抵靠在第一止挡面上。 当处理盒完成安装后， 成像装置的显影联 结器通过驱动力传递组件来驱动显影辊旋转， 复位扭簧的第一扭臂由抵靠在第 一止挡面上过渡到抵靠在端部的外壁上， 随着显影辊在显影时的旋转， 复位扭 簧的第一扭臂再由抵靠在端部的外壁上过渡到抵靠在第一圆弧面上， 从而反复 循环。 当处理盒从成像装置中取出后， 可控制复位扭簧的第一扭臂抵靠在第一 止挡面上， 从而处理盒再次安装到成像装置时， 驱动头突起的位置与上一次安 装时的位置一致， 驱动头突起更能顺畅地与显影联结器接合。 [0020] Further, when the reset portion protruding end portion of the outer wall is provided, before the process cartridge is mounted to the image forming apparatus, resetting a first torsion arm of the torsion spring against the first stop face. After the process cartridge is completely installed, the developing coupling of the image forming apparatus drives the developing roller to rotate by the driving force transmitting component, and the first twisting arm of the reset torsion spring is transitioned against the first stop surface to abut against the end portion. On the outer wall, as the developing roller rotates during development, the first torsion arm of the reset torsion spring is further abutted against the first circular arc surface by abutting against the outer wall of the end portion, thereby repeatedly circulating. After the process cartridge is taken out from the image forming apparatus, the first twist arm of the reset torsion spring can be controlled to abut against the first stop surface, so that when the process cartridge is mounted to the image forming apparatus again, the position of the drive head protrusion is the same as the last installation. The position is uniform, and the driver head projections are more smoothly engaged with the developing coupler.
[0021] 此外， 当复位部内凹端部的外壁设置时， 在处理盒安装到成像装置前， 复位扭 簧的第一扭臂抵靠在第二止挡面上。 当处理盒完成安装后， 成像装置的显影联 结器通过驱动力传递组件来驱动显影辊旋转， 复位扭簧的第一扭臂由抵靠在第 二止挡面上过渡到抵靠在第二圆弧面上， 随着显影辊在显影时的旋转， 复位扭 簧的第一扭臂再由抵靠在第二圆弧面上过渡到抵靠在导向面上， 接着复位扭簧 的第一扭臂通过抵靠在导向面上再次过渡到抵靠在端部的外壁上， 从而反复循 环。 当处理盒从成像装置中取出后， 可控制复位扭簧的第一扭臂抵靠在第二止 挡面上， 从而处理盒再次安装到成像装置时， 驱动头突起的位置与上一次安装 时的位置一致， 驱动头突起更能顺畅地与显影联结器接合。 [0021] Further, when the end portion of the outer wall of the concave portion is provided to reset, before the process cartridge is mounted to the image forming apparatus, a first reset torsion arm of the torsion spring abuts against the second stop surface. After the process cartridge is completely installed, the developing coupler of the image forming apparatus drives the developing roller to rotate by the driving force transmitting component, and the first twisting arm of the reset torsion spring is transitioned against the second stop surface to abut against the second circle On the curved surface, as the developing roller rotates during development, the first twisting arm of the reset torsion spring is further abutted against the guiding surface on the second circular arc surface, and then the first twist of the torsion spring is reset. The arm re-circulates by abutting against the guide surface again to abut against the outer wall of the end. After the process cartridge is taken out from the image forming apparatus, the first twist arm of the reset torsion spring can be controlled to abut against the second stop surface, so that when the process cartridge is mounted to the image forming apparatus again, the position of the drive head protrusion is the same as the last installation. The position is uniform, and the driver head projections are more smoothly engaged with the developing coupler.
[0022] 同时， 驱动头突起的顶端与端部的第二端面之间的距离为6.0毫米， 端部的直径 为6.0毫米， 在落机过程中使驱动头突起更能顺畅地与成像装置的显影联结器接 合， 避免了驱动力传递组件卡死在显影联结器的情况， 以提高处理盒在落机过 程的顺畅性， 提高打印品质。 [0022] At the same time, the distance between the tip end of the driving head protrusion and the second end surface of the end portion is 6.0 mm, and the diameter of the end portion is 6.0 mm, which makes the driving head protrusion more smoothly and the imaging device during the landing process. The developing coupling is engaged to avoid the situation that the driving force transmitting component is stuck in the developing coupling to improve the smoothness of the process cartridge during the falling process and improve the printing quality.
