The invention relates to a system having: a first longitudinal member and a second longitudinal member arranged symmetrical to the first longitudinal member in relation to a longitudinal mid-plane of the conveyor system, to define a forward movement track and a return track of the rollers ; a connecting crossbeam for connecting the longitudinal members. The power transmission device transmits the rotary force to the rotary member in a non-contact manner such that a vibration of one rotary member is not transmitted through the power transmission device to another component of the image forming apparatus. The receptacle also includes a guide post that is located adjacent to the side and extends along the side toward the connector face. The carrier structure includes an aperture that receives the at least one protrusion. A communication module is coupled to the partial power source and is configured to communicate with a receiver and an antenna electrically coupled to the communication module, which uses the antenna to communicate with the receiver.
