Abstract
A transducing device converts to representative electrical signals those force variations which are produced by the act of a person writing a signature. In the device, a signature writing surface is provided, and is part of an arm attached by resilient means to a support member which in turn is secured to a base. A magnetic core is connected to the underside of the signature writing surface and coacts with a plurality of coils mounted on the base to provide a motion transducer which, with associated circuitry, generates an electrical signal which varies in accordance with the varying forces applied to the signature writing surface as a signature is written thereon. Stop rods secured to the base limit the extent of travel in one direction of the signature writing surface.
