<p>DATA READING DEVICE FOR DATA PROCESSING APPARATUS In a data processing apparatus, a device for reading data stored in a card is provided with a housing having a slit through which the card can be manually inserted and engaged by guides within the housing for movement in a predetermined path to an operative position, a slider member movable within the housing and having a portion interposed in the path of the card so as to be engaged by the latter and moved thereby, against the force of at least one spring, from an initial position to a displaced position upon insertion of the card through the housing slit to its operative position, a lock assembly engageable when the card is inserted to its operative position for holding the slider member in its displaced position against the force of the spring, and a lock release for disengaging the lock assembly and thereby permitting the spring to return the slider member to its initial position during which the card is propelled outwardly through the housing slit. A roller urged against the guided card within the housing frictionally resists separation of the card from the slider member when the latter is held in its displaced position and also during return of the slider member to its initial position. A muting circuit is made operative as the card moves to and from its operative position in which conductive terminals connected through a printed circuit with one or more data storage elements on the card are engaged with respective contact elements within the housing.</p> |
