ABSTRACT:
Camera and imaging processing apparatus for producing rippled message images in frame areas of specular surfaced photoplastic film having a conductive substrate below an upper heat-softenable and image rippleable emulsion layer. Images are formed by image patterned electrostatic charge and heat deformation, and are erased at higher temperatures for re-recording. A film support includes a lateral platen having an opening to permit contact of the back of the film with a moveable heatable metallic block to effect conduction heat softening. The conductive substrate of the film is held at ground potential, and a charging apparatus interposed between the film and an objective lens, through which the image to be recorded is projected, imposes a large electrostatic charge differential on the platen to cause the film to be snugged to the platen. The charging apparatus includes a housing which defines an optical aperture. A shutter mechanism is provided between the objective lens and the charging apparatus to control irradiation of the film by the image beam.
