  • Patent number: 9396619
    Abstract: Disclosed herein is an apparatus for receiving cash and checks. The apparatus includes a bundle transfer unit, a semi-separation unit and a sheet-by-sheet separation. The bundle transfer unit transfers a bill bundle input into the apparatus. The bundle transfer unit is provided above and below the bill bundle and extends along a path for transferring the bill bundle. The semi-separation unit is installed behind a rear end of the bundle transfer unit. The semi-separation unit limits the number of bills to be transferred in such a way that only a preset number of bills separated from the bill bundle is allowed to pass through the semi-separation unit. The sheet-by-sheet separation unit is installed behind a rear end of the semi-separation unit. The sheet-by-sheet separation unit separates bills transferred from the semi-separation unit from each other sheet-by-sheet.

  • Patent number: 8965568
    Abstract: A feed station has a pre-separation region, a separation region and a transport region in succession along a transport path. A first sensor is at the start of the separation region and a second sensor is at the start of the transport region. A control unit processes signals from the sensors and encoders to determine the position of the flat item, and is connected with a separation motor to drive the separation device, so that a flat item is separated from a stack with a predetermined separation velocity. If unacceptably small gaps exist between the flat items, the separation process is stopped when the leading edge of a subsequent flat item reaches the second sensor and is continued when the preceding separated flat item achieves a predetermined clearance from the leading edge of the aforementioned flat item due to its transport.

  • Publication number: 20110200375
    Abstract: A portable printer having improved ergonomic and operational characteristics. The printer includes an asymmetrically-damped media centering mechanism having first and second media support members moveable along a common longitudinal axis and configured to grasp roll media. The media support members are coupled to a reciprocal movement mechanism configured to translate a longitudinal movement of the first media support member into a corresponding opposite longitudinal movement of the second media support member. A pivoting arm is coupled to the reciprocal movement mechanism. The pivoting arm pivots to a first position when the first and second media support members are moved closer to each other, which causes a damping gear to engage the reciprocal movement mechanism, thereby damping the grasping motion of the media support members and providing an improved user experience.

    Abstract: A mail doubles detection and correction system for a mail processing system with a feeder includes a mail support configured to support at least two mail pieces in a detection space downstream of the feeder, a pair of vacuum belt assemblies disposed on opposite sides of the detection space, and one or more sensors positioned about the detection space to detect a position of one or more mail pieces in the detection space. Each vacuum belt assembly includes a vacuum port facing the detection space and a perforated belt movable across the vacuum port in a mail transport direction. The system detects a mail double when the sensors indicate that more than one mail piece is disposed in the detection space and corrects the situation by moving one of the belts and holding the other belt stationary to advance only one of the mail pieces, and subsequently moving both of the belts to advance the remaining mail piece.
