IN THE UNITED STATES PATENT AND TRADEMARK OFFICE PATENT APPLICATION For: AN IMPROVED PARTICLE BEAM RECORDER SYSTEM HAVING A REFERENCING MEANS FOR ESTABLISHING REGISTRATION HOLES IN A FILM SUBSTRATE Abstract Of The Disclosure An improved particle beam recorder system is provided having a film gate which includes a referencing means for providing at least two differently shaped registration holes in a recording film substrate. The referencing means lock in, secure, and define the film position relative to a film receiving surface of a film gate during exposure imaging and thereby establish a defined relation between the image field and the film substrate and more particularly the registration holes thereof. The developed film image can thereafter be positioned in a predefined or desired relationship in a display means by aligning the registration holes of the film with suitable pegs of the display means. The registration holes also advantageously permit the images of exposed and developed films to be aligned relative to one another to permit accurate superimposition. The referencing means for producing the registration holes can be punch means which pierce the film. The punches are activated by a motor driven cam and controlled by an interlock circuit which disables the cam motor and the film advance motor during film exposure imaging. The referencing or punch means can be utilized in extended position during film exposure to secure the position of the film relative to the film gate.
