ABSTRACT:
A printing or stamping device for marking checks and similar documents comprises a rotatable type ring having a plurality of types around its periphery and a keyboard having a plurality of manual key-switches each corresponding to one type on the type ring. An angular position detector detects the angular position of the type ring and includes a coded disc which rotates in synchronism with the type ring and develops successive position signals indicative of the successive angular positions of the type ring. Control circuitry including a memory stores data typed-in on the keyboard and transmits successive typed-in signals to a coincidence detector which detects the coincidence of a typed-in signal and the corresponding position signal and provides a coincident signal. The coincident signal activates a stopper mechanism to stop the rotation of the type ring at a position where the typed-in type faces the check. A lever system then pivots the type ring to print that type on the check after which the check is advanced one space in readiness for the next printing. After the printing and advancement of the check, the stopper mechanism releases the type ring and the cycle is repeated until all of the typed-in data is printed on the check.
