Detailed Description of Preferred Embodiments
The present invention relates to an automatic developer/printer apparatus for obtaining photographic prints from a negative as shown in FIG. 1. The developer/printer apparatus comprises a projection assembly 1 having at least one light source 2 positioned below at least three subtractive filters 3, preferably motor-driven, a negative carrier 4 in which developed film negatives move, an optical apparatus 5, and a projection chamber 6. The apparatus further comprises an exposure darkroom 7, provided with photosensitive material preferably in strip form loaded in a magazine 8, and a projection plane 9 perpendicular to the light projected through a negative from projection assembly 1 against which is fitted the photosensitive material.
Darkroom 7 also contains at least one cutting element 10 and at least one advancing element 11 for advancing the photosensitive material against and in front of projection plane 9. Developer 12 comprises a plurality of treatment tanks 13 in darkroom 7 in which are located paper feed means 14 into which cut photosensitive material is fed. The developer/printer apparatus additionally comprises a drying chamber 15 and a treatment product reservoir 16 contained in a housing 20.
Projection assembly 1 is positioned parallel and adjacent to exposure darkroom 7, with darkroom 7 positioned above developer 12, and housing 20 containing drying chamber 15 and treatment product reservoir 16 is positioned under projection apparatus 1 and against developer 12. Through this arrangement the apparatus is easy to use and is very compact.
Projection assembly 1 is movably mounted to darkroom 7 perpendicular to projection plane 9 of darkroom 7 on the housing. Optical apparatus 5 is movably mounted to projection assembly 1 perpendicular to the horizontal plane of negative carrier 4 and is adapted to more synchronously with projection assembly 1 so that as projection assembly 1 is repositioned, optical apparatus 5 likewise repositions automatically. This arrangement allows negatives to be enlarged and ensures that light projected through a negative is focused and projected onto projection plane 9.
Projection assembly 1 is connected to darkroom 7 by a bellows 17 through which is projected light projected through a negative. Bellows 17 permits projection assembly 1 to move in a horizontal plane with respect to projection plane 9 of the darkroom. The horizontal plane passes through negative carrier 4 that is positioned in projection assembly 1 perpendicular to projection plane 9 of darkroom 7 and parallel to the displacement of projection assembly 1 on housing 20. Horizontal displacement of the projection assembly is effected by means of a lead screw 18 rotationally guided in bearings 19 integral with housing 20 that contains treatment product reservoir 16 and drying chamber 15. Lead screw 18 cooperates with projection assembly 1 by means of screws 21 attached laterally under the projection assembly. A roller or slide surface 22 guided by a slide path 23 integral with housing 20 and parallel to the axis of lead screw 18 (FIG. 2) permits movement in the horizontal plane.
Optical apparatus 5 is movably mounted perpendicular to the direction of displacement of projection assembly 1. Displacement occurs automatically through action of a cam to ensure that light projected through a negative is focused and projected in darkroom 7. Optical apparatus 5 moves vertically above negative carrier 4 as a function of the enlargement ratio desired and occurs synchronously with the displacement of projection assembly 1. Synchronous displacement is governed by lead screw 18, which is preferably motor-driven.
According to a preferred embodiment, synchronicity of displacement is controlled by a microprocessor, which, as a function of the enlargement ratio displayed on panel 24 and preferably positioned on projection assembly 1, calculates the displacement that projection assembly 1 must effect, which in turn governs the position and height of optical apparatus 5 as a function of the displayed enlargement ratio.
Reflection mirror 25 inclined at a 45.degree. angle with respect to the horizontal plane of the negative carrier in projection chamber 6 is interposed between optical apparatus 5 and bellows 17 to reflect the light projected through the negative and optical apparatus through bellows 17 to projection plane 9 of darkroom 7. Mirror 25 must be positioned manually when the position and height of optical apparatus 5 is adjusted, and must be positioned at a distance from negative carrier 4 to permit enlargements. Negative carrier 4 preferably is mounted rotatably under optical apparatus 5 thus permitting at least two enlargement formats on the photosensitive material strip of a predetermined width. For example, negative carrier 4 can provide enlargement formats such as 330 mm.times.460 mm (13".times.18") and 460 mm.times.610 mm (18".times.24") by simply rotating the image 90.degree. with respect to the paper used and by displacing projection assembly 1 and optical apparatus 5 as a function of the desired enlargement ratio.
Optical apparatus 5 preferably is movable, and projection assembly 1 is adapted to accept at least three types of lenses corresponding to three negative formats. The apparatus according to the invention thus makes it possible to obtain a large number of enlargement formats for different types of negatives. Advancement of the negative, preferably manually, is effected by any means known to one skilled in the art. It is obvious also that advancement of the negative can be controlled automatically by a microprocessor. Displacement of projection assembly 1 and optical apparatus 5 also can be obtained manually by known means, e.g., by a handle, rack, or other, so as to enlarge and focus an image formed by light projected through a negative onto projection plane 9 in exposure darkroom 7.
The darkroom preferably is provided with means for verifying the enlargement format and the focus of the light projected through a negative on projection plane 9. Verification means comprises at least one frosted glass 26 positioned on one of the lateral surfaces of darkroom 7 so as to be visible by the user, and by at least one pivotable mirror 27 mounted in the darkroom. The pivot axis of mirror 27 is vertical, and the mirror can be positioned manually from the exterior of the darkroom by a handle or by any known automatic means from panel 24, such as, for example, by an electromagnet. Mirror 27 is pressed against frosted glass 26 during exposure of the photosensitive material to the light projected through a negative from the projection assembly, thus ensuring that no stray light enters the darkroom. During verification, this mirror can be interposed on the projected light in a manner so as to reflect the light on frosted glass 26 preferably at a 45.degree. angle. A stop abutment makes it possible to correctly align mirror 27. The light image obtained on mirror 27 is the reverse of the negative, but will be the same size as that to be exposed on the photosensitive material. This reflection makes it possible to easily modify the enlargement by having a real view of the dimensions of the final product.
The light exposes a photosensitive material such as paper bearing a photosensitive emulsion on photosensitive surfaces. The paper is the form of a roll and is stored in magazine 8 of darkroom 7. The magazine is of sufficiently large width so as to accept a roll of paper corresponding to the maximum width of the enlargements desired. The paper roll is easily interchangeable and is maintained in the magazine by any known means allowing for its free rotation. Magazine 8 protects the photosensitive paper roll from stray light.
Magazine 8 preferably comprises a braking and tensioning system 28 preventing any undesired unwinding of the paper roll due to inertia. This magazine is positioned in the rear portion of darkroom 7 behind projection plane 9. Paper preferably is fed out of the upper portion of magazine 8 and directed above projection plane 9. The paper is then vertically oriented by roller 30. Paper advancement means 10 are positioned below projection plane 9 and comprise at least two horizontal rollers 29, parallel to the axis of the paper roll, and in contact with one another. Rollers 29 make it possible to tension the paper in front of projection plane 9 and to advance this paper after each exposure. The paper is maintained taut in front of and against projection plane 9 by means of rollers 29 and 30 so that the paper does not deform. A vertical plate 31 positioned between two horizontal cylinders 32 guides the movement of the strip of paper when it is advanced. Paper passing in front of plate 31 and behind cylinders 32 is stretched and maintained against plate 31 during advancement of the paper between cylinders 32. After exposure, paper is advanced by a length equal to the height of the exposure imparted on the paper. The paper is then cut by at least one cutting element 10 positioned behind paper advancement rollers 29.
Cutting element 10 comprises a known apparatus such as a fixed blade and a movable blade, preferably activated electrically as a function of the advancement of the paper. According to the preferred embodiment, cutting and advancement of the paper are controlled by a microprocessor that calculates, as a function of the enlargement ratio displayed on panel 24, the advancement length and the cutting of the paper once the calculated length has been advanced. The exposed paper, after being cut, falls by gravity into developer 12 positioned under darkroom 7. It is guided through its fall by spout 33.
Spout 33 preferably moves in a horizontal plane with respect to developer 12 allowing for the distribution of paper at different points across the width of developer 12. Production of the apparatus can be increased by increasing the pace of advancing, exposing, and cutting of the paper. Horizontal displacement of spout 33 is obtained by any means known to one skilled in the art, and the speed of displacement can be controlled by a microprocessor as a function of the advancement of the paper.
Developer 12 comprises a plurality of tanks 13, preferably of the same height, containing treatment products necessary for developing, such as developer, fixer, water, and other compounds. Tanks 13 are each provided with at least one aperture 34 centered over an axis formed by the vertical walls separating the tanks between side walls of the tanks. Aperture 34 serves as an entryway to the paper feed means 14 fixed in each tank. Paper feed means 14 comprises rollers 35 rotatable on shafts 36 (FIG. 4) guided in bearings provided in parallel side plates 37 and 38. Rollers 35 are evenly spaced parallel to each other in a vertical plane and are all of the same length and diameter. Paper feed means 14 further comprises a plurality of parallel endless belts 39 (FIG. 3) mounted between two shafts 40 guided in bearings provided in side plates 37 and 38. These belts run in evenly spaced grooves in shaft 40 and are adapted to be displaced linearly with respect to rollers 35. Shafts 40 are parallel to the axis of rollers 35 and are positioned respectively above first roller 35 and below the last. Upper shaft 40 preferably is mechanically driven. Belts 39 operate perpendicular to the axes of rotation of rollers 35 and 40 and are in contact with rollers 35 and pressed there against by cylindrical rods 41 loosely mounted in bearings provided in side plates 37 and 38 parallel to the axis of rotation of the rollers and positioned in the median portion of the space separating rollers 35 and 40.
Paper feed means 14 further comprises a semi-circular support element 42 partially surrounding, without being in contact with, last roller 35. Elements 42 are positioned between two series of endless belts 39 and redirect the direction of paper movement in a treatment tank 13. Treatment product in each tank is filled to the level of first roller 35. In each tank the paper follows a path that is substantially "U-"shaped. The semi-circular support forms the links between the decending and ascending path of the paper in each paper feed means 14. According to a preferred embodiment, semi-circular supports 42 are movable on paper feed means 14 and can be positioned readily under each roller 35. This makes it possible to modify the length of the path covered by the paper in the treatment product contained in tank 13, thus making it possible to adjust the time of passage of the paper in the treatment bath. These semi-circular supports comprise a plate 43 in which are provided a semi-circular cutout 44 adapted to surround a roller 35, an opening 45A through which a shaft 45 passes, and two orifices 46 through which attachment rods pass. These attachment rods are fixed in the bearings of cylindrical rods 41 after retraction of these rods.
At the inlets and outlets of paper feed means 14 formed by aperture 34, the paper is guided between two series of parallel rotating shafts 47. One series is positioned to receive substantially vertically received paper from spout 33 with outboard shafts having smaller diameters than the inboard shafts so that the paper travels in an arc as it is conducted to endless bands 39 to begin its passage through the treatment bath. Shafts 47 are mounted in bearings provided in side plates 37 and 38 that preferably form a "T"-shape. The series of shafts at the level of output of the paper can comprise a supplemental shaft 47 such that the paper will exit out of paper feed means substantially perpendicular to the rotation plane of rollers 35.
Paper feed means 14 further comprises on its upper portion and in the vertical plane of rotational rollers 35 a crossbar 48 that can extend beyond both sides of the paper feed means or connect to side plates 37 and 38. This crossbar supports the feed means in tank 13 once it is lowered through aperture 34. It is obvious that the paper feed means 14 are of a sufficient width to accept large format papers and to allow for the lateral distribution of papers substantially on a lateral plane described by the lateral movement of spout 33. The rotating elements of each of paper feed means 14 are driven in rotation by an endless chain 49 activated by motor 50. Endless chain 49 engages each of the paper feed means by at least one pinion 51 attached to a shaft. All of these pinions are at the same height in the paper feed means in developer 12. All of the rotationally driven shafts extend over at least one of the sides of the paper feed means. Movement of endless chain 49 is transmitted through pinion 51 to all of the rotating shafts by a series of gears 52 in each of paper feed means 14. Intermediate gears between the gears on shafts 36 of rollers 35 are carried by shafts 45 to prevent the chain from sagging. Endless chain 53 engages at least two pinions 54 positioned preferably behind the gears of the first and last rollers 35 on the paper-feed means so as to avoid any interference with gears 52.
It is obvious that all elements comprising the paper feed means are resistant to corrosive treatment products.
The paper, after its exposure and cutting, is under the control of the rotating elements of the first paper feed means of developer 12 and is treated by passing through the different tanks 13. Transfer from one tank to another occurs automatically by the series of shafts 47 that are physically close to one another from one feed means to another. The paper is dried at the outlet of the developer. According to a preferred embodiment, drying chamber 15 extends horizontally from the extension of the outlet of the last feed means 14 of developer 12 and is positioned in housing 20 above which is movably mounted projection assembly 1. The drying chamber comprises endless belts 55 stretched between two shafts 56 that are positioned horizontally under rollers 57 rotating in the same horizontal plane and whose rotational axes are perpendicular to belts 55. These belts move horizontally with respect to developer 12. Paper coming out of developer 12 is taken between belts 55 and rollers 57 and is brought towards a sorting table 58. The sorting table preferably comprises an endless belt positioned and adapted to move horizontally in a direction perpendicular to the outlet of drying chamber 15 so that the order of photographs previously modified by displacement of spout 33 above developer 12 is proper.
Endless chain 49 driven by a motor 50 drives belts 55 and rollers 57. Chain 49 engages a pinion 59 integral with one of shafts 56. Movement is transmitted to a roller 57 by gears, and a series of intermediate gears transmits the movement to all of the rollers 57. Drying preferably is achieved by means of ventilation. It is obvious that the movement of the endless belt from sorting table 58 can be associated with the movement of belts 55.
Treatment product reservoir 16 is positioned under drying chamber 15 and housing 20. This reservoir is connected to developer tank 12 by means of pumps (not shown). It is obvious that the present apparatus according to the invention comprises overflow pipes, drainages, and other accessories.
According to a second embodiment of the invention shown in FIG. 5, the developer/printer apparatus comprises a fixed projection assembly 1 that can be positioned under exposure darkroom 7. Darkroom 7 comprises photosensitive material magazine 8 with spout 33 by which prints falling by gravity are guided to and distributed in developer 12. Developer 12 is positioned against housing 20 containing drying chamber 15 and on which is placed projection assembly 1 and darkroom 7. According to this embodiment, the enlargement of prints is obtained by a "zoom" lens 59 positioned above light source 2, subtractive filters 3, and a negative carrier 4. The light projected through a negative can be projected without being reflected by a mirror directly onto a projection plane. Enlargement and focus are obtained directly by the "zoom" lens that is automatically activated, for example, by a cam driven by a microprocessor. By way of example, the "zoom" lens is of a type commercialized by BETAVARON SCHNEIDER COMPANY. This lens, by being positioned at approximately 650 mm from the projection plane, makes it possible to obtain photographic prints of the format 71 mm.times.108 mm (3.5" by 4") up to 230 mm.times.350 mm (9".times.14") from a negative of the standard 24 mm.times.36 mm format type. It is obvious that other elements and characteristics described in the first embodiment of the apparatus are appropriate to the second embodiment.
The present invention makes it possible to automatically obtain prints and enlargements from a negative in an easy and rapid manner. The apparatus is of simple construction and facilitates use. It is obvious that the present invention can receive other improvements and other variations within the domain of technical equivalents without going beyond the scope of the present patent.
