  • Publication number: 20140140728
    Abstract: A bearing mechanism for connection with a photosensitive drum and an electronic imaging device includes a transmission member for coupling a rotary driving member of the electronic imaging device, a conductive piece at an inner portion of the transmission member, a conductive bar, and a spring member. The transmission member is synchronously rotatably mounted to the photosensitive drum and includes a through hole. The conductive bar is slidably mounted into the through hoe of the transmission member for electrically contacting a conductive shaft of the electronic imaging device. The spring member is electrically connected between the conductive piece and the conductive bar for providing a rebound force forcing the conductive bar to move away from the inner portion of the transmission member. In this way, the axial offset between the transmission member and the rotary driving member can be compensated.

  • Publication number: 20140129029
    Abstract: A proximity sensing apparatus is provided. The proximity sensing apparatus includes an encoded signal transmission unit, an interference signal transmission unit and a reception unit. The encoded signal transmission unit transmits an encoded signal, and the interference signal transmission unit transmits an interference signal. The interference signal interferes with the encoded signal to generate an interfered signal. The reception unit receives a sensing signal and outputs the sensing signal to a signal processing unit. The sensing signal is either the interfered signal or the encoded signal. The signal processing unit is electrically connected to the reception unit, and determines whether the sensing signal matches the encoded signal. The signal processing unit further outputs a proximity signal when the sensing signal does not match the encoded signal.
