SHEET 1 OF 3 IHIIIIIIIIIHIHIIHIIIIIIHIIIIIIHIIfIIHH 44 EE 1]. 4 can PHOTOCOMPOSING MACHINE WITH MAGNIFICATION MECHANISM The present invention is directed to a photocomposing machine in which light is directed from a light source through a font and onto a refracting surface for redirection to a photo-sensitive sheet of material.
It sometimes may be desirable to change the size of the characters that are being projected onto the photosensitive sheet. To do this, the magnification of the projecting system is changed. This entails the use of different lenses for receiving the images of characters of a particular font. Heretofore, the magnification of the characters has been changed by complicated mechanisms for moving lenses into and out of position of the image of the characters. This, in turn, requires complicated control mechanisms which increases production and maintenance costs.
The present invention eliminates these drawbacks and has, for one of its objects, the provision of an improved mechanism for a photocomposing machine whereby improved means are provided for changing the magnification of the characters.
Another object of the present invention is the provision of an improved photocomposing machine wherein a pair of lenses are slidably mounted in the path of the light beam to change the magnification of the image.
Another object of the present invention is the provision of an improved means for permitting the lenses to slide easily from one position to another.
Other and further objects of the invention will be obvious upon an understanding of the illustrative embodiment about to be described or will be indicated in the appended claims and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.
A preferred embodiment of the invention has been chosen for purposes of illustration and description and is shown in the accompanying drawings, forming a part of the specification, wherein:
FIG. 1 is a diagrammatic view of the photocomposing machine to be used for the present invention;
FIG. 2 is a view of the font used in the present invention;
HO. 3 is a top view of the lens-shifting mechanism used in the present invention;
FIG. 4 is a detailed side view thereof; and
H6. 5 is one end view of the mechanism.
The photocomposing machine in which the present invention is particularly adapted to be used is described and shown in US. Pat. application Ser. No. 825,692 filed May 19, 1969 is schematically shown in FIG. 1.
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 coherent light source which gives a monochromatic beam such as a laser or a zeon 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 is continuously rotated by motor 19. The drum assembly 4 comprises drum 4c, having a film strip 4b consisting of a plurality of fonts of transparent characters 4e and 4d. When the light beam 17 is generated, as explained in greater detail hereinafter, it is directed to 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 17b 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. In other words, as each character image 17b is flashed onto the sheet 16, 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.
At the end of a line the film 16 is moved upwardly so that another line can be printedQThe film then passes through a developer mechanism 23 and is then cut by cutting mechanism 24 into strips for future use andassembly.
Above the bank of characters 4d and 4e on the rotating drum film strip 4b, there is provided a plurality of counting gate openings or strobes 18. One gate opening 18 is 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. When the photo diode 5 is activated 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 themto 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 slowed and the light power supply 2 is activated to flash the light source 1.
It is sometimes desirable to utilize different magnifications for the characters being projected. According to the present invention, the lens system 8 comprises a plurality of lens assemblies 8a and 8b, two of which are shown in the drawing, each of which will give a different magnification to the character that is being projected onto the photo-sensitive sheet 16. The lens assemblies 8a and 8b are adapted to slide back and forth in the path of the beam 17b in order to give a different magnification to the image. If desired, a plurality of sliding lens assemblies may be used if more than two magnifications are desired.
Each lens assembly 8a and 8b comprises a tubular lens holder 30 mounted in a frame 31 provided with slide bars 32. The lens holders 30 protrude from a slidable front plate 33 which is connected to a rear stabilizing plate 34 by means of standards 35. The front and rear plates 33 and 34 have bearing elements 36 which are adapted to permit sliding movement on the slide bars 32.
The lens system 8 is slidable back and forth by means of a motor 38 operating on gear racks 39 through gear elements 40,41 and 42. The gear racks 39 are mounted on the front and rear plates 33 and 34. It will be noticed that by energizing the motor 38, the lens assembly slides either in one direction or in the other so as to give a different magnification to the beam 17b. Switches 37 are provided at each end of the frame 31 which are adapted to be tripped by the lens system 8 in order to be certain that the lenses are in position.
It will thus be seen that the present invention provides an improved mechanism for a photocomposing machine whereby means are provided for changing the magnification of the characters and which includes a pair of lenses easily slidable mounted in the path of the light beam.
As changes may be made in the construction and arrangements of the parts herein without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in a limiting sense.
