    Abstract: A high-speed on-the-fly type of printing mechanism which includes three printing stations for producing three separate records of a transaction. A slidably-mounted carriage supports the printing hammer and drives the type wheels which constitute the three printing stations. The carriage is reciprocally driven by a cam-actuated drive mechanism which is motor-driven. The type wheels are mounted on a pair of rod members forming an assembly which is moved by the carriage during its reciprocal movement.

    Abstract: A matrix plate switch controlled by a cash register for use in operating a change-dispensing mechanism which includes a printed circuit board and a switch blade frame separated by a pair of movable mylar matrix plates. The matrix plates are connected to and positioned by rack members in the cash register to align holes located in said matrix plates so as to allow switch contacts to sense a predetermined area of the circuit board, thereby selectively operating the change dispenser to dispense change according to the setting of a rack member of the cash register.
