The wiring fixture has a base unit, which is to be mounted on a predetermined position, and a functional unit that is formed as a removable structure and is to be electrically connected to the base unit. The image decoding unit decodes a data stream and generates a plurality of image comprising a current image. A replacement fluid may be applied after inking and after removal of the dampening fluid. The sealing element has a sealing body of substantially U-shaped configuration to define two sealing lips in coaxial parallel relationship to the vertical pot axis. The device can reduce the amount of the electric current consumed unnecessarily during the discharging operation by differing the reference voltages of a cell power voltage discharge unit and a cell power voltage generation unit during a portion of a discharging period.
