Assembly for image forming device with movable drive coupler
The granted patent (Publication Number: US11914322B2) discloses an assembly for an electrophotographic image forming device. The assembly includes a rotatable drive coupler that can move between a retracted position and an extended position. In the retracted position, the drive coupler is disengaged from a corresponding drive interface of a replaceable unit, while in the extended position, it is engaged with the drive interface to provide rotational force. A lever connected to the drive coupler facilitates the movement between the two positions based on the insertion of a replaceable unit. Additionally, biasing members are included to retain the drive coupler in the desired position when the replaceable unit is removed.
Furthermore, the patent describes a system for an electrophotographic image forming device that includes an imaging basket and an image transfer unit. The system features a rotatable drive coupler that can be moved between a disengaged and engaged position to provide rotational force to the drive interface of the image transfer unit. An actuator connected to the drive coupler facilitates the movement based on the insertion or removal of the imaging basket. The system also includes biasing members to ensure the drive coupler remains in the disengaged position when the imaging basket is removed. Overall, the patent details a mechanism for efficient operation and interaction between various components in an electrophotographic image forming device.
