A card reader card capture clamp having a base plate for slidably receiving a card. A switch detects movement of the card past a predetermined position and produces a "card insertion" signal representative thereof. A clamp plate pivots between a clamped position in which the card is clamped between the two plates, and an unclamped position in which the card is movable relative to the plates. The clamp plate is biased into the unclamped position in the absence of production of the card insertion signal. A solenoid coupled between the two plates is actuated upon production of the card insertion signal to overcome the biasing and move the clamp plate from the unclamped into the clamped position. The switch includes two switch arms respectively pivotally mounted on opposed rearward ends of the clamp plate. Magnets are provided on the switch arms, and magnetic field sensors are mounted adjacent to the switch arms. Movement of the card past the predetermined position moves the switch arms relative to the magnetic field sensors, causing the sensors to detect magnetic field changes and to thereupon produce the card insertion signal. A clamping detection sensor detects movement of the clamp plate into the clamped position and produces a "card clamped" signal representative thereof. The clamping detection sensor includes a magnetic field sensor mounted on the clamp plate and a magnet mounted adjacent to the clamp plate. Movement of the clamp plate from the unclamped into the clamped position moves the magnetic field sensor relative to the magnet, causing the magnetic field sensor to detect a magnetic field change and to thereupon produce the card clamped signal.

[ What is claimed is:] [1.]1. A card reader card capture clamp, comprising:(a) a base plate for slidably receiving a card;(b) a switch for detecting slidable movement of said card past a predetermined position on said base plate and for producing a card insertion signal representative thereof;(c) a clamp plate pivotally connected to said base plate for pivotal movement of said clamp plate relative to said base plate between:(i) a clamped position in which said card is clamped between said clamp plate and said base plate;(ii) an unclamped position in which said clamp plate is biased away from said base plate to allow movement of said card relative to said clamp plate and said base plate;(d) biasing means coupled between said clamp plate and said base plate to bias said clamp plate away from said base plate into said unclamped position in the absence of production of said card insertion signal; and,(e) a solenoid having a first portion coupled to said clamp plate and a second portion coupled to said base plate, said solenoid operable upon production of said card insertion signal to overcome said biasing means and pivotally move said clamp plate from said unclamped position into said clamped position.
