  • Patent number: 5593044
    Abstract: An apparatus for sorting sheet-like items, in which the items, which are to be sorted to plural collecting sections, can be easily recycled to a feeder for sorting the items in multiple sorts in accordance with a desired sorting order or sequence. A stacker is provided on an upper portion of feeder. By pulling out a bottom plate of the stacker, the once sorted items in the stacker are caused to fall down into the feeder. The items can thus be rapidly recycled to the feeder for another sort, thereby reducing the time required for complete sorting or sequencing of the mail.

  • Patent number: 5537266
    Abstract: In a tape loading device of the invention, a tape is taken out by tape guides mounted on an inclined loading ring, and the loading ring is rotated to wind the tape on a rotary drum from one side thereof. An auxiliary inclined guide is provided between the rotary drum and the leading tape guide. Only during a loading operation, the auxiliary inclined guide contacts the tape, while angularly moved about the leading tape guide. When the loading operation is completed, the auxiliary inclined guide is disengaged from the tape. With the provision of the auxiliary inclined guide, the tape is prevented from being twisted between the rotary drum and the leading tape guide.
