Programming apparatus

An apparatus for programming a hand-held, programmable electronic calculator of the type having a plurality of depressible keys, said programming apparatus comprising in combination:

• a program card having a plurality of apertures therein forming a matrix defined by a plurality of rows and columns;
• a plurality of command pins, each for being restrained within a selected one of said apertures within one of said rows, thereby representing a programming command;
• a frame for receiving therein said calculator and for providing registration between said columns of said program card and said depressible keys of said calculator;
• a plurality of levers coupled to said frame, with each of said levers paired with and juxtaposed to one of said columns of said program card and juxtaposed to a corresponding one of said depressible keys of said calculator for actuating said paired one of said depressible keys responsive to the displacement of said lever by said command pin;
• and
• cam means rotatable about an axis generally perpendicular to said columns of said program card for engaging said command pins in one of said rows and moving said command pin in said program card through communication with said corresponding one of said levers, thereby sequentially actuating said depressible keys for programming said calculator.
