Abstract

Document handlers and copier glass platens are often damaged when the document handler is allowed to crash into the glass platen. The reason for these crashes are varied and include: - Counter weighting mechanism failure. - Damping mechanism failure. - User closes ( returns) the document handler to fast.

PROTECTIVE DEVICE FOR Proposed Classification DOCUMENT HANDLERSICOPIERS U.S. C1.355/308 Lloyd F. Bean Int. C1. GOlJ 3/06

Document handlers and copier glass platens are often damaged when the document handler is allowed to crash into the glass platen. The reason for these crashes are varied and include:

- Counter weighting mechanism failure. - Damping mechanism failure.
- User closes ( returns) the document handler to fast.

This damage can be eliminated by providing an acceleration or velocity sensor and arresting mechanism which stops the movement of the closing document handler when its acceleration and/or its velocity reaches predetermined values. That is, the mechanism senses an impending crash and stops the document handler's movement. The acceleration sensor can be similar to the auto seat restrainer mechanism. The velocity sensor could be a centripetal clutch mechanism.
