  • Sorter
    Patent number: 5377972
    Abstract: A sorter for sorting sheets out is provided with a bin unit including a plurality of bins having specified length and width and a bin shifting mechanism for shifting the bin unit upward and downward. The respect ire bins are vertically spaced apart and adapted for placing the sorted sheets thereon. The sorter is further provided with a first detector for detecting that the bin unit has been moved down to a home position region defined in a lower portion of the sorter, and a shift controller for controlling the bin shifting mechanism. The shift controller shifts the bin unit downward until the first detector conducts the detection when the bin unit is not in the home position region when the power is applied the sorter. Accordingly, the home position of the bin unit can be detected accurately with a simple structure.

  • Sorter with rotary spirals and guide rails
    Patent number: 5305994
    Abstract: A sorter includes a sheet processing device, a plurality of bin trays arranged in a vertical direction, each bin tray having a specified width and length and adapted for bearing a sheet, shifting means for shifting the plurality of bin trays in the vertical direction, and moving means for moving the bin tray in a predetermined position in a lengthwise direction of the bin tray so that the sheet on the bin tray is processed by the sheet processing device. The bin tray can be moved to a position where sheet processing is to be applied by the sheet processing device.

  • Sheet finishing device with calculating means for efficient operation
    Patent number: 5290020
    Abstract: An automatic sheet processing device mountable on a sorting unit of an image forming apparatus includes a sheet processor for applying a sheet processing to a sheet having a specified length and width, a moving unit capable of supporting the sheet processor for moving the sheet processor along a side of the sheet, and a controller having a storage unit for storing sheet processing data, a calculator for calculating a processing position from the sheet processing data, and a control portion for controlling the moving unit so as to move the sheet processor to the calculated processing position. The processing position is calculated from the stored sheet processing data, and the sheet processor is moved to the calculated processing position, so that sheet processing can be automatically.
