Primary Examiner-John M. Horan Attorney, Agent, or Firm-Holland, Armstrong, Wilkie & Previto [5 7] ABSTRACT The use of a plurality of lenses projecting a character to permit different magnifications thereof. 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.

42 Claims, 8 Drawing Figures PAIENTEU JUL301974 SHEETHOFS MULTILENS PI-IOTOCOMPOSING MECHANISM DESCRIPTION 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.

It is sometimes desirable to magnify characters that are being projected onto the photo-sensitive sheet and for this purpose, different lenses with different magnifications may be used for viewing the characters of a particular font. Heretofore, 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.

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 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; and

FIG. 8 is a sectional view taken along line 8-8 of FIG. 4.

Referring more particularly to the drawings and particularly to FIG. 1, the photocomposing machine to be used with the present invention is described and shown in US. Pat. application Ser. No. 825,692 filed May 19, 1969 and 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 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. 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 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. 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 26 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.

Above the bank of characters 4d and 4e on the rotating drum film strip 4b, there is provided a plurality of counting gate openings 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 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.

In order to obtain different magnifications for the characters on the font 4b, 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. A beam-directing assembly 30 comprising mirror assemblies 31 and 31a moves in a circular path around beam 17b and moves the mirror assemblies 31 and 31a into alignment with the lens assemblies 8a to 8h to direct the light beam 17 through a preselected lens assembly 8a to 8h. The beamdirecting assembly 30 comprises a pair of periscope mirror assemblies 31 and 31a movable in unison around beam 17b as an axis. The path of the light beam 17b is reflected from the reflector 25 in the drum 4 to the rotating mirror 9 through the selected lens assembly 8a to 8h by means of the periscope mirror assemblies 31 and 31a.

Each mirror assembly 31 and 31a comprises an inner mirror 35 and 35a and an outer mirror 36 and 36a, respectively, connected together in parallel relationship to each other. 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. Preferably, the beam 17f is an extension of the original beam 17b and is in precisely the same position as the original beam 17b. Hence, as 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.

ln the construction of the invention, shown in FIGS. 3 and 4, the lens assemblies 8a to 8h are mounted peripherally on a lens frame 32 which is centrally located on the lens assembly 30. Each lens number 8a to 8h comprises a cylindrical lens holder 33 and a lens 34 mounted therein. The different lenses have different magnifications. The lens assemblies 8a to 8h are preferably held in place by suitable lens clips 50.

Mounted centrally of the lens assembly 30 and extending through the frame 32 is a rotatable shaft 40 which is attached to a drive gear 41. A position wheel 43 is mounted on the shaft 40 for rotation therewith. The position wheel 43 has a plurality of openings 42 therein, one of which is in alignment with opening 38a in the mirror assembly 31a. The other end of the shaft 40 has the other mirror assembly 31 which is mounted on the frame 44 and which is rotatable with shaft 40. Thus, when the shaft 40 is rotated, both mirror assemblies 31 and'31a are rotated together.

As pointed out above, each mirror assembly 31 and 31a comprises an inner mirror 35 and 35a and an outer mirror 36 and 36a in parallel relationship to each other and are connected together by a frame 39 and 39a. The inner opening 37 and 37a in the frame are in alignment with beam 17b and 17f and an outer opening 38 and 38a are in alignment with the opening 42 on the position wheel 43, the beam 17d and the lens assemblies 8a to 8h.

Thus, when the position wheel 43 is rotated, the openings 38 and 38a will be positioned from one lens to another lens.

The drive gear 41 moves the wheel 43 until the opening 42 and mirror assemblies 31 and 31a are in alignment with the desired lens assembly 8a to 8h. The wheel 43 has fine adjustment pins 44 thereon which are adapted to be acted on by fork-like adjuster 46 controlled by solenoid 47 in order to move the wheel until the mirror assemblies 31 and 31a are in proper position.

The wheel 43 is provided with a weight 51 and with test mirrors 48 and 49 used to adjust and test the machine before it is used.

With the above construction, it will be seen that when different magnifications of a character from the same font is desired, it is merely necessary to energize a drive which rotates the mirror assembly 30 until the periscope mirror assemblies 31 and 31a are opposite the desired lens, at which point the drive is stopped and the fine adjustment fork 46 is activated to engage the fine adjustment pins 44 so that the periscope assemblies 31 and 31a are placed in the exact position to pass the light beam through the desired lens assembly 8a to 8h.

Hence, the present invention provides an improved mechanism for a photocomposing machine whereby means are provided for changing the magnification of the characters, for using stationary lenses and a-movable mirror assembly and for permitting the mirror assembly to move easily from one position to another.

As various changes may be made in the form, construction and arrangement 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.
