    Abstract: A sheet feeder includes a sheet placing portion, a feeding member, a supporting body, a driver, an electromagnetic clutch and a retraction controller. The supporting body is capable of changing a posture between a sheet feeding posture of the feeding member and a retracting posture for retracting the feeding member. The electromagnetic clutch is capable of changing a state between an engaged state in which a drive force is transmitted to the supporting body and a disengaged state in which the drive force is not transmitted to the supporting body. The retraction controller stops the output of a drive force after the electromagnetic clutch is set in the engaged state and the supporting body is set to the retracting posture by the drive force, and sets the electromagnetic clutch in the disengaged state when an engagement keeping time elapses after the output of the drive force is stopped.

  • Publication number: 20100320676
    Abstract: A system and method for monitoring media stack height utilizes a pick mechanism and stack height sensing mechanism. The pick mechanism has a pick arm and a pick roller, the arm rotatably mounted at one end to pivot about an axis and change its angular position relative thereto. The roller rotatably mounted to an opposite end of the arm contacts a media stack top and is rotatably driven to feed sheets one at a time from the stack top changing the stack height. The angular position of the arm relative to the stack changes as the stack height changes. The stack height sensing mechanism arranged on and adjacent to the arm senses arm angular displacement as the stack height changes to provide an indication of the sheet quantity remaining in the stack. A method for calibrating stack height sensing of the monitoring system provides one or more calibration points such as at “full stack” and “stack out” conditions.

    Abstract: A paper feeding device includes a supporting base and a paper arranging module. The supporting base has a supporting surface, an inclined supporting plane and a slot at the supporting surface. The paper arranging module includes a pivot structure fixed under the supporting surface, a paper-pushing structure pivoted to the pivot structure, an elastic element connected between the paper-pushing structure and a fixed end, and a cam disposed on the pivot structure. When a first supporting part of the cam corresponds to the paper-pushing structure causing the paper-pushing structure to be driven by the elastic element, the paper-pushing structure moves toward the inclined supporting plane along the slot to arrange the paper on the supporting base, thereby facilitating subsequent paper dividing. When a second supporting part of the cam corresponds to the paper-pushing structure, the paper-pushing structure is returned to an original position by a driving force of the cam.

The first combination of media is an uppermost combination of media in the media stack. The method includes gripping the first combination of media and bending along a first axis by moving a first portion away from the media stack. The first combination of media is bent along a second axis by moving a flexing member while in contact with a second portion of the first combination of media, wherein the second axis is not parallel to the first axis. The first combination of media is repeatedly bent along the second axis while pausing movement of the first combination of media between the first bending along the second axis and the second bending along the second axis.
