  • coding means readable by the machine for determining number and arrangement of the electric contact elements in said casing to insure matching of said casing with the corresponding apparatus;

    said coding means including grooves provided in said casing and pins removably insertable in said grooves to provide a predetermined code determined by presence and non-presence of said pins in said grooves, so that presence of a first pin in a first groove provides one code information and non-presence of a second pin in a second groove provides another different code information;

    said grooves having a preselected spacing from each other and from walls of said casing; and

    said grooves being provided with wall means to removably secure said pins in said grooves so that said pins can only slide into and out of said grooves.
