A top panel 21 is secured to upper edges of the front and rear edge members 17 and 18 and to upper edges of the end edge members 19 and20 to form a planar work surface. The top panel 21 has a work portion 22 adjacent one end edge member,as for example, member 19, and an opaque portion 23 adjacent the other end edge member 20.
An elongate guideway 24is formed in an upper surface of the toppanel 21 and extends longitudinally between end edges thereof and substantially parallel with the rear side or edge member 18. The guideway 24 is'shaped to receive a registry slide member 25 for movement therealong, as later described. A transverse guideway 26 is formed in the upper surface of the top panel 21 and is positioned between the work portion 22 and the opaque portion 23 and extends between the front and rear side members 17 and 18. The transverse guideway 26 receives a master positioning slide member 27 for movement therealong, as later described.
A generally rectangular or square exposure window 28 is positioned in the work portion 22 of the top panel 21 and has a rear edge 29 adjacentand parallel with the elongate guideway 24. The exposure window 28 also has a side edge 30 adjacent and parallel with the transverse guideway 26. A generally rectangular or square registry window 31 is positioned adjacent the exposure window 28 and has a rear edge 32 adjacent and parallel with the elongate guideway 24. The rear edge 29 of the exposure window 28 and the rear edge 32 of the registry window 31 are longitudinally aligned and parallel with the elongate guideway 24.
The registry window 31 has a grid formed of a plurality of longitudinally spaced grid lines 33 and a plurality of transversely spaced grid lines 34 which intersect the longitudinally spaced grid lines 33 thereby forming frames for positioning respective images on an image-bearing negative 35, as later described.
A plurality of spaced and aligned recessed pin receiving bushings 36 are positioned adjacent the edges of the exposure window 28 and adjacent the edges of the registry window 31 for fastening various material in precise relation thereto during production of camera ready copy, as later described.
A punch 37 is mounted on the top panel 21 adjacent the rear side member 18 and is adapted to punch or perforate a master 38 or image-receiving material 39, as later described. The perforations are in the form of a plurality of aligned apertures 40 adjacent at least one edge of the master 38 and a plurality of aligned apertures 41 adjacent at least one edge of the image-receiving material 39, respectively. The apertures 40 and 41 are spaced and aligned to correspond to and register with the pin receiving bushings 36 adjacent the edges of the exposure window 28 and the registry window 31.
It is desirable that the punch 37 have extremely high accuracy and repeatability and automatically clamp in position material to be punched immediately prior to punching same in conjunction with the punching motion and it is desirable that the punch effectively center the material being punched, therefore, a punch corresponding to the punch disclosed in my U.S. Pat. No. 3,169,725 on Punching Apparatus Having Means to Center workpiece is employed with the step and repeat apparatus 1.
A chamber 42 is positioned below the top panel 21 and has an exposure compartment 43 below and enclosing a lower surface of the exposure window 28. An exposure lamp 44 is positioned within the exposure compartment 43 for exposing the image-receiving material 39 thereby reproducing images from the image-bearing master 38 onto the image-receiving material 39.
The chamber 42 has a registry compartment 45 below and enclosing a lower surface of the registry window 31 and a registry lamp 46 is positioned within the registry compartment 45 for illuminating the registry window grid formed of the grid lines 33 and 34 thereby precisely positioning the image-bearing negative 35 prior to forming the master 38, as later described.
A handle 47 is mounted on the table portion and is operatively connected to the registry slide member 25 for moving same along the guideway 24 to position the imagereceiving material 39 relative to the image-bearing negative 35 in the master 38, as later described. In the illustrated structure, a miter gear 48 is mounted on one end of a shaft 49 extending from and turned by the handle 47. The miter gear 48 meshes with a miter gear 50 mounted on one end of an elongate gear shaft 51 having a spur gear 52 mounted on the other end thereof. The spur gear 52 is positioned to interengage with a rack gear 53 on a lower surface of the registry slide member 25 for moving same longitudinally along the guideway 24 in response to turning the handle 47. The gear shaft 51 is rotatably supported by sleeves 54, suitably supported in the chamber 42, as by being secured to and depending from the top panel 21.
A handle 55 is mounted on the table portion 15 and is operatively connected to the master positioning slide member 27 for moving same along the transverse guideway 26 to position the master 38 relative to the exposure window 28. In the illustrated structure, a shaft 56 extends downwardly through the top panel 21 and has a miter gear 57 on a lower end thereof. The miter gear 57 interengages and meshes with a miter gear 58 on one end of an elongate gear shaft 59 having a spur gear 60 on the other end thereof positioned to interengage with a rack gear 61 on a lower surface of the master positioning slide member 27 for moving same along the transverse guideway 26. The gear shaft 59 is rotatably supported by a plurality of sleeves 62 secured to and depending from the top panel 21.
A vacuum pump' or motor 63 is mounted on the table portion 15 and is operative to evacuate the exposure compartment 43 by creating a vacuum therein which will hold a selected master 38 and image-receiving material 39 in firm contact with the exposure window 28. A lip or flange 15 extends inwardly from surfaces defining an opening for the exposure window 28 and suitable resilient material 65 is supported on the flanges 15'. The resilient material 65 and the material forming the exposure window 28 are spaced from the opening defining surfaces to provide for vacuum air veins 64 around the exposure window 28 for evacuating the exposure compartment and drawing the master 38 and image-receiving material 39 into firm contact with the exposure window 28. The material forming the exposure window 28 has a plurality of small parallel grooves in the upper surface thereof which communicate with the air veins 64 thereby providing vacuum means for holding the master 38 and the image-receiving material 39 in firm contact with the exposure window 28. The vacuum pump or motor 63 is activated by a switch 66 mounted on the front side member 17 for easy access thereto.
A timer 67 is operatively connected to the exposure lamp 44 positioned within the exposure compartment 43 whereby the desired duration of exposure of the image-receiving material 39 to the image or images of the image-bearing negative 35 in the master 38 may be accurately and precisely controlled by an operator (not shown). The timer 67 has a pointer 68 for indicating the duration of the exposure time and a suitable switch, such as a pushbutton 69, for activating the timer 67 and the exposure lamp 44.
Visual display means, such as indicators 70 and 71, are operatively engaged with the registry slide member 25 and the master positioning slide member 27, respectively, for indicating the position thereof. The indicators 70 and 71 have dials 72 and 73 respectively to visually display the position of the respective slide member with microconsecutive readout with no accumulative error and no backlash.
In using the step and repeat apparatus 1, the dials 72 and 73 are positioned at a zero initial reading. A suitable negative carrier sheet 74, such as a sheet of laminated opaque and clear material, is placed in the punch 37 where the apertures 40 are punched adjacent one side edge thereof. The negative carrier sheet 74 which will become the master 38 after securing the image-bearing negative 35 thereto is held in pin registry at the registry window 31 and adjacent a right side edge 75 thereof, as seen in FIG. 2. Pins 76 are inserted through the apertures 40 and are received in the pin receiving bushings 36 at the right side edge 75 of the registry window 31 with an enlarged head portion 77 thereof engaging the sheet 74 for accurately holding same in position. A negative receiving window 78 is formed in the negative carrier sheet 74, as by cutting through and peeling away a portion of the opaque material forming said negative carrier sheet 74. The registry lamp 46 is turned on by a suitable switch 79 mounted on the front side member 17 for convenient access thereto. The image-bearing negative 35 is positioned within the negative receiving window 78 of the negative carrier sheet 74 and is positioned with the images thereon properly positioned relative to the grid formed by the grid lines 33 and 34. Upon proper alignment with the grid and the registry slide member 25, the image-bearing negative 35 is suitably secured to the negative carrier sheet 74, as by being taped thereto, thereby forming the master 38.
The completed master 38 is then transferred to pin registry at the exposure window 28 wherein the position of the pin receiving bushings 36 are identical with the location of the pin receiving bushings 36 at the right side edge 75 of the registry window 31. The pins 76 are inserted through the apertures 40 in the master 38 and are received in the pin receiving bushings 36 adjacent the side edge 30 of the exposure window 28 with the head portions 77 thereof holding the master 38 in precise centered location relative to the exposure window 28 and the master positioning slide member 27. The master 28 is then suitably secured to the master positioning slide member 27, as by tape, and the pins 76 are removed whereby the master 38 may be moved relative to the exposure window 28 through movement of the master positioning slide member 27 by the handle 55.
The image-receiving material 39, such as a sheet of raw film, photosensitive material, plates or the like, is placed in the punch 37 which is operative to form the apertures 41 along one edge thereof. The image-receiving material 39 is held in pin registry adjacent the rear edge 29 of the exposure window 28 by placing the pins 76 through the apertures 41 and into the pin receiving bushings 36 adjacent said rear edge 29. The image-receiving material 39 is then suitably secured to the registry slide member 25, as by tape, and the pins 76 are removed from the respective bushings 36 adjacent the registry slide member 25. The position of the photosensitive or imagereceiving material 39 is now on the exact longitudinal center line of the exposure window 28. The switch 66 is then manipulated to activate the vacuum pump or motor 63 for drawing and holding the master 38 and the image-receiving material 39 into firm vacuum contact with the exposure window 28. The pointer 68 of the timer 67 is adjusted to the desired exposure time and the pushbutton 69 is actuated to turn on the exposure lamp 44 and activate the timer 67 for exposing the imagereceiving material to the selected image on the image-bearing negative 35 of the master 38.
In the event that the image-bearing negative 35 has a plurality of images thereon to be exposed to the image-receiving material 39, the vacuum switch 66 is turned to the off" position thereby breaking the vacuum contact between the master 38 and image-receiving material 39 with the exposure window 28. The registry slide member 25 is then moved to the next position by turning the handle 47 to position the image-receiv ing material 39 relative to the next image on the imagebearing negative 35. The vacuum contact is then repeated, the exposure is repeated and the vacuum contact is broken before the image-receiving material 39 is moved to align with each succeeding image in the image-bearing negative 35. This procedure is continued until the first longitudinal row is completed. The master positioning slide member 27 is then adjusted to position the image-bearing negative 35, relative to the image-receiving material 39, for a second longitudinal row of exposures, and any portion of the exposure window 28 uncovered by moving the master 38 is masked or covered, whereby the registry slide member 25 may then be adjusted to position the image-receiving material 39 in precise alignment with the images on the master 38 and the vacuum contact and exposures are accomplished in a reverse direction along the second longitudinal row. Additional rows of images and exposures will be made in the longitudinal and transverse directions by the same methods. After final exposure of the image-receiving material 39, it is removed from the apparatus 1 and processed in a normal manner. The registry slide member 25 is movable in a single linear motion in the guideway 24 and the master positioning slide member 27 is movable in a single linear motion in the transverse guideway 26 with the movements being used conjunctively to make all necessary adjustments for the step and repeat exposures.
