  • ABSTRACT Primary Examiner-John M. Horan Attorney, Agent, or Firm-Holland, Armstrong, Wilkie & Previto [5 7] ABSTRACT
  • the lenses are stationary and there is a movable reflector mechanism that directs the images of the character through any selected lens of the system.
  • the present invention is directed to a photocomposing machine in which a light beam is directed from a light source through a font and onto a reflecting surface for redirection to a photo-sensitive sheet of material.
  • photocomposing machines have utilized complicated mechanisms for moving lenses in and out of position for receiving the light through a particular character. These require complicated control mechanisms which increases the cost of maintenance and manufacture of such machines.
  • the present invention eliminates these problems and has, for one of its objects, the provision of an improved photocomposing machine with improved means for changing the magnification of the characters of a font.
  • Another object of the present invention is the provision of an improved photocomposing machine wherein a plurality a lenses are provided and a movable beamdirecting assembly is provided to direct the beam through a preselected lens.
  • Another object of the present invention is the provision of an improved means for permitting the lenses to remain stationary and for moving the beam-directing assembly to the proper position without complicated aligning mechanisms.
  • FIG. 1 is. a diagrammatic view of the photocomposing system in accordance with the present invention.
  • FIG. 2 is a section of the transparent type font which may be used with the present invention.
  • FIG. 3 is a top elevational view of the light beam assembly mechanism in accordance with the present invention.
  • FIG. 4 is a side view of the lens system.
  • FIG. 5 is a front end view thereof
  • FIG. 6 is a rear end view thereof
  • FIG. 7 is a sectional view taken along line 7-7 of FIG. 4.
  • FIG. 8 is a sectional view taken along line 8-8 of FIG. 4.
  • a source of light 1 is powered by a power supply 2 to create an intense, short burst of light 17 at a wave length most suited for the light-sensitive material or film 16 being used.
  • the source of light 1 may be any high intensity light source which gives a monochromatic beam, such as a laser or a flash tube. Of course, other light sources may also be used if desired.
  • the light beam 17 may pass through a modulator (not shown) and continues to a character font drum assembly 4.
  • the font drum assembly 4 which is continuously rotated by motor 19.
  • the drum assembly 4 comprises drum 40, having a film strip 4!; consisting of a plurality of fonts of transparent characters 42 and 4d.
  • a redirecting mechanism 25 which in the drawings is shown as being a penta reflector. It is then redirected through a selected character in the font strip 4b and the image 171) formed of that character is directed to a lens system 8.
  • the lens system 8 will direct the character image 17b to a reflecting surface 9, which is shown in the application as a mirror, for reflecting the character image 17b onto the photo-sensitive film 16 as at 26.
  • the mirror 9 is moved by a motor 10 so that the image 17b of the character projected by the mirror 9 will be directed to a different part of the photo-sensitive film 16 to form the line 26.
  • the mirror 9 is adjusted to sweep an arc across the face of photo-sensitive material 16 so that a line of characters 26 is impressed thereon.
  • the mirror 9 is rotated predetermined increments so that the line 26 will be justified.
  • the distance between the mirror 9 and the paper film 16 is so great that the distortion of the image projected on the paper is minimal, if at all.
  • the film is moved upwardly so that another line can be printed.
  • the film then passes through a developer mechanism 23 and is then cut by cutting mechanism 24 into strips for future use and assembly.
  • a plurality of counting gate openings 18 are mounted in line with characters 4d and 4e.
  • the drum 4c is provided with a light source 27 adapted to project light through each gate 18 as the gate 18 passes thereby. The light is directed onto a control photo diode 5.
  • a pulse is generated which is fed into a counter mechanism 6.
  • the output of this counter 6 is fed to a gate 7 (which is connected to the light power supply 2) and represents one of the conditions of the gate 7.
  • a tape reader 12 is adapted to sense code combinations on a tape (not shown) and transfer them to an electronic computer (not shown) which has predetermined character and line data therein and which has stored therein a particular number count to each character. The count is transferred to the gate mechanism 7 and when the count of a particular character is reached by the counter 6 it coincides with the count from the computer to satisfy conditions of gate 7.
  • a pulse is sent to the light powered supply 2 and to the character width and spacing electronics (not shown). However, the signal to the power supply 2 is inhibited. After a time interval, e.g., 2 microseconds, the mirror 9 is moved a predetermined angle directly proportional to the width and spacing of the particular character to be reproduced. As soon as the mirror is in position, the inhibit is released and the light power supply 2 is activated to flash the light source 1.
  • the beam 17b is directed to different lens assemblies 80 and 8h in the lens system 8 after it has passed through a character in the font 4b.
  • a plurality of stationary lens assemblies 8a to 8h are preferably mounted in a circular path with the light beam 17b acting as the axis.

  • the beamdirecting assembly 30 comprises a pair of periscope mirror assemblies 31 and 31a movable in unison around beam 17b as an axis.

  • the outer mirrors 36 and 36a are in alignment with the center lines of the lens assemblies 8a through 8h so that when the mirror assemblies 31 and 31a are moved, the outer mirror 31a will be moved from one lens assembly to another lens assembly.
  • the position of the inner mirror 35 which is in line with the beam 17b is at such an angle to the beam 17b so as to reflect the beam in an upward direction 170 onto the outer mirror 36.
  • the outer mirror 36 is parallel to and faces the inner mirror 35 and is in such a position so that the beam 17c is redirected in a horizontal path 17d preferably at right angles to the upward beam 17c.
  • the beam 17d is preferably parallel to the beam 17b and is so positioned as to go through the center line of the preselected lens assembly 8a to 8h.
  • the assembly 31a is similarly constructed so that the beam 17d is reflected at right angles by outer mirror 36 to form a vertical beam l7e which is again reflected at right angles by inner mirror 35a to form an emerging beam 17f which is then directed against reflecting mirror 9.
  • the beam 17f is an extension of the original beam 17b and is in precisely the same position as the original beam 17b.
  • the mirror system 30 which is comprised of a pair of periscopically mounted mirrors 31 and 31a is rotated and moved from one lens assembly to another, the beam 17b is made to travel in the path described above and passes through the selected lens to give the image the desired magnification.
