ABSTRACT:
In a reproduction apparatus, such as a copier, having a document feeder mounted on top of a scanner, a restraining mechanism is provided to restrict the pivotal travel of the feeder in relation to the pivotal travel of the scanner. This restraining mechanism, while allowing the feeder to pivot from the scanner so that one may copy items such as books, restricts such pivoting in relation to the scanner, when the scanner is pivoted from its normal operation position. This prevents the feeder from pivoting to a point where it would make contact with objects to the rear of the copier that may damage the feeder.
The restraining mechanism is comprised of a cable connected to the feeder and the copier housing, with said cable being fed over cable guides, a sheave and a pendulum means. This restraining mechanism provides an interaction between the scanner and the feeder such that the greater the pivotal movement between the scanner and the copier housing, the lesser the pivotal movement between the scanner and the feeder. The pendulum means supports the sheave and also maintains the cable taut and in contact with the cable guides to prevent cable dislodgment and operational jamming.
