Abstract: A peripheral or stand-alone computerized stamp printer is provided particularly for office use in which a print assembly including a pressure cam and leaf spring arrangement is associated with a heated print head which contacts and impresses a daisy wheel character against an imprinting tape in a confined cartridge to serially print computer-selected letters or characters on a binder, binder spine, or other workpiece. The printer assembly may move on an X or Y axis along a fixed or movable gantry upper arm. If the gantry is fixed, means are provided for moving paper stock, binders or other workpieces into proper position for clamping on a work surface on the top surfaces of the printer chassis. A spine-holding drawer may be provided in the chassis for supporting the spine of a binder for printing letters, logos, or the like, on the binder spine. The print assembly is a discrete unit and includes a replaceable tape cartridge fitted into drive mechanisms within the printer assembly.

Abstract: Apparatus for generating color slides or other photographic media containing character fonts and graphics images contains one or more character font sets on a transparent drum or disk carrier. Lines of text are entered by keyboard or the like into a data processor which stores them as character and position information. This information is then used to position and expose images of the selected characters from the carrier onto photographic media by use of a moveable lens and a shutter. An additional moveable drum or disk may be used to provide different background color as well as character color. By holding the shutter open while a character or arbitrary shape is illuminated, two-dimensional graphics image can be recorded on the photographic media by controlling the movement of the lens in two dimensions. A method is also provided for providing a continuously variable transmission of light through a liquid crystal shutter to control exposure of the photographic media.
