Abstract
A cartirdge or cassette for containing light-sensitive web material for application to utilization apparatus is provided with mechanical encoding on one of the cartridge end caps, in the form of a series of protrusions and/or recesses. The protrusions or recesses are formed by injection molding in one of the exposed walls of the end cap and provide a binary code which, in cooperation with utilization apparatus, prevents the improper insertion and utilization of the cartridge. The code positions are formed during set-up of the mold in which the end cap is formed by injection molding by the selection of cooperation pairs of mold pins in recesses provided in the mold halves, to form either a recess or a protrusion in the form of a pin in each of four possible code positions. The protrusions have closed ends and are hollow, so that the breaking off of a protrusion by attempted improper utilization permits light to enter the interior of the cartridge through the protrusion and end cap.
