Definitions
- length of a display composition is the length of a roll of web paper, whereas the normal machine composes in lateral lines across a sheet of approximately 8 inches width and then the sheet is leaded one line and another line of text is composed.
- any large display composed in this manner would be limited to about 8 inches.
- FIGURE of the drawing illustrates the invention in schematic arrangement, because the details of photocomposition or photographic type composition machines are sufficiently old and well-known that they need not be set forth in detail, and will be well understood by those skilled in the photocomposition art.
- a disc 10 is illustrated as the matrix character source, and although modern photocomposition disc fonts are .much' more complex with many more characters than the original composition machines, the function of disc 10 is essentially that of a rotating transparency font just as in the above-referenced early photographic type composition machine.
- the computer 13 may also be used to control other functions of photocomposition but its primary purpose is to find 'and'project an image of a proper character from the disc 10.
- the commonly used character source is a transparency disc, but those skilled in the art may desire to select a transparent disc with opaque characters or an entirely opaque character with a reflex illumination of characters done in a contrasting color on the surface of the disc.
- the invention is not confined to a transparent disc 10, but any original object holder and means to illiminate an object positioned on that holder.
- the compensator lens 14 is a primary lens positioned to gather light rays from the illuminated object and form an aerial image 16 of the object at the focal length of the lens 14.
- a first composing system comprises a collimating lens 18 and a de-collimating lens 20 optically coupled.
- This type of optical system is taught by prior art U.S. Pat. No. 2,670,665 and others before it.
- the purpose of the collimating and de-collimating lenses is to permit a composition by shifting the de-collimating lens 20 after each exposure of a character in order to provide letter spacing.
- a mirror 26 is placed in the optical axis of the de-collimating lens 20 and the image directed at a right angle to the optical path.
- the letters are stepped along in a line composition on the plane in which a sheet of photosensitive material 28 is positioned.
- the sheet 28 is a coated lightsensitive paper fed in leaded steps by a film cassette.
- a line is composed by stepping the lens and the mirror 26 from left to right until the line is filled, and then returning while the film cartridge leads the photosensitive paper 28 one line.
- composition escapement in the preferred embodiment is accomplished by means of a rack 30 attached to a holding bracket 31 on which the lens 20 and mirror 26 are mounted.
- a pinion 32 is driven by a motor 34 to step the carriage 31 along in proper escapement dimensions.
- the motor 34 is a stepper motor which is also controlled by the computer 13.
- a second photocomposing system is established by the provision of a negative lens 36 into the optical system to branch off to a separate photosensitive sheet.
- the normal path of the lens 20 and mirror 26 is the extent that reflection from mirror 26 will fall upon the large sheet 28.
- the frame 31 is shiftable by the motor 34 under control of the computer to a parked position shown in full line in the drawing. Composition in this mode is achieved solely by paper movement and not by stepping of the mirror.
- the first optical system is composed of lenses and a mirror to produce text of point size within a range covering a bulk of normal composition.
- the second branch may be maintained in the same point size to produce long strips of text, but usually a lens will be inserted to change the point size, and the most common use is to insert a diverging lens to produce large display size composition.
- a convertible phototypesetter and display size type printing machine comprising:
- this lens being a primary lens positioncd to gather light rays from said illuminated object and form an aerial image of the object at the focal length of the lens;
- a first composing system comprising:
- a second composing system comprising:
