Definitions

  • the invention relates to a device for producing photographic copies according to the preamble of patent claim 1.
  • the requirements for maximum compactness with simultaneous structural simplicity and optimal functional arrangement of the individual components should be created.
  • the printer and the paper processor are at right angles to one another, which results in a particularly favorable and space-saving arrangement.
  • printer and paper processor are always in line.
  • a sheet turner is provided which carries out the necessary deflection of the copy material sheets to be developed.
  • this sheet turner preferably also simultaneously adapts the speed of the printer and paper processor, and thus acts as a buffer.
  • FIG. 1 shows the outer outline of the device according to the invention, hereinafter referred to as "Minilab", and only to the extent necessary for understanding the invention.
  • a copying or enlarging device P commonly referred to as a printer
  • a so-called paper processor PP commonly referred to as a printer
  • a film processor FP film processor
  • a film and paper dryer D and a chemical supply and disposal part R are arranged in a common light-tight housing G.
  • all components are per se standard. All that is new is their mutual arrangement and various details, which are explained in more detail below.
  • the printer P Only the elements important for understanding the invention are shown by the printer P. These are a copying light source 1 (here physically attached to the film processor FP), a film stage 2 for positioning the film to be copied in the imaging beam path 3, an imaging optics 4, a paper stage 5 for positioning the photographic copying material K, a knife 6 for cutting off individual ones Scroll B from the copy material K located in a paper cassette 7 and rolled up into a roll.
  • the paper cassette 7 is in can be coupled to and disconnected from the printer P in a known manner.
  • the paper processor PP which is also conventional per se, has a series of treatment tanks 15-17, 17a arranged one behind the other, through which the individual exposed copy material sheets are passed in a known manner in a meandering path 18. Of the means of transport necessary for this, only a few transport rollers 19-23, 23a are indicated schematically in the drawing.
  • the developed sheets leave the paper processor PP at its outlet 24 and from there directly into the dryer D, where they can be removed after drying.
  • all functions run automatically under the control of an electronic control.
  • the structure and mode of operation of the film processor FP, the dryer D and the preparation and disposal part R are irrelevant to the present invention and therefore do not require any special explanation.
  • the central point of the mini-lab according to the invention is the already mentioned sheet turner ST.
  • This consists essentially of a (here) twelve pairs of rollers 31-42 arranged roller rack (Fig. 3, 5), which is arranged about a vertical axis A through an angle ⁇ 'of 90 ° (Fig. 1).
  • the rollers 37-42 located on the same rack side are kinematically connected via a (toothed) belt 43.
  • a swivel drive (motor or magnet) 44 is provided for pivoting the roller rack (FIG. 4). In one pivot position of the roller rack (FIGS. 1 and 3), its rollers 31-42 are located parallel to the transport rollers 8-14 of the printer P, in the other pivot position they are parallel to the transport rollers 19-23 of the paper processor PP.
  • the transport planes of the printer P and the paper processor PP are designated by t 1 and t 2.
  • the transport paths of the copy material sheets are shown for clarification as (in reality, of course, nonexistent) belts b1 and b2.
  • the transport planes t1 and t2 are each spanned by any movement direction vector r1 or r2 and by any normal n1 or n2 on the transport paths b1 and b2.
  • r1 or r2 are each spanned by any movement direction vector r1 or r2 and by any normal n1 or n2 on the transport paths b1 and b2.
  • n1 or n2 on the transport paths b1 and b2.
  • there are an infinite number of transport levels but obviously all of them are parallel to t1 or t2.
  • it does not depend on the absolute position, but only on the mutual orientation of the transport levels t 1 and t 2.
  • the printer P and the paper processor PP are arranged substantially at right angles to one another, which means that their respective transport planes t 1 and t 2 are at exactly this right angle ⁇ to one another.
  • the intersection line of the two transport planes is designated by s in FIG. 2.
  • the pivot axis A of the sheet turner or roller rack ST symbolized by a rectangle is arranged parallel to the cutting line s, which results in the above-mentioned movement geometry for the rollers of the sheet turner ST in relation to those of the printer P and the paper processor PP when the rollers of the sheet turner stand perpendicular to its swivel axis A.
  • the rollers 31-42 of the sheet turner ST in the place of which wheels, disks or the like could also be provided without further ado, have no separate drive. Rather, depending on the position, they are coupled to the means of transport of either the printer P or the paper processor PP and are also driven by it.
  • the printer P is provided with a spring-loaded drive wheel 25 which, in the position of the roller rack shown in FIG the bottom roller 42 connected coupling wheel 45 (Fig. 4) and drives it.
  • a further coupling wheel 46 is connected in a rotationally fixed manner to the top roller 37 of the rack and, in the position of the sheet turner ST shown in FIG. 4, engages with a likewise spring-loaded drive wheel 26 provided on the paper processor PP (FIG. 5).
  • the two drive wheels 25 and 26 each have a kinematic connection with the transport rollers of the printer P or the paper processor PP and rotate accordingly.
  • the sheet turner ST establishes the connection between the printer P and the paper processor PP. In its swivel position shown in FIGS. 1 and 3, it picks up one sheet of copy material exposed from printer P (between the transport rollers 12 and 14 vertically emerging upwards) and is in its other swivel position shown in FIGS. 4 and 5 to the paper processor PP, where it is captured and transported by means of its pair of inlet rollers 19/20.
  • the ST sheet turner which is designed to be light-tight, fulfills other important functions. On the one hand, it acts as a buffer memory between the printer P and the paper processor PP and decouples these two components in terms of the work cycle. The copy material is usually transported much faster in the printer than in the paper processor.
  • the individual sheets can now be inserted very easily into the roller rack at the relatively high speed of the printer and removed from the rack again at the relatively low speed of the paper processor.
  • the printer is not blocked by the sheet turner and can already bring a new sheet into the copy position and expose it.
  • the input 27 of the paper processor PP is located above the copying level 5 of the printer and opens downward. This can at best result Chemical vapors are prevented from entering the sensitive printer room.
  • the low-lying arrangement of the copying plane 5 enables the preferred top-down exposure for many reasons with a straight, undisturbed exposure beam path and the arrangement of the paper cassette 7 on the floor that is desired for the operator (for reasons of weight).
  • the sheet turner ST now not only effects the redirection of the exposed copy material sheets due to the right-angled arrangement of the printer and paper processor, but at the same time also bridges the level difference between the printer and the paper processor, which is also advantageous for other reasons because of the high arrangement of the paper processor.
  • the ST sheet turner has another important function.
  • the copying material K lies in the printer P with the light-sensitive layer side up, which is indicated in FIG. 2 by the full dots 50.
  • the back of the copying material is symbolized by rings 51.
  • the paper processor PP it has proven to be advantageous if the photographic material is guided in such a way that it lies in the individual treatment tanks with its layer side facing outwards, that is to say the layer side faces the tank walls. With conventional minilabs, both requirements could not be met at the same time. This means that if the printer was used to print from top to bottom, the copy material in the paper processor ran with the layer side inwards. However, if the copy material in the paper processor was in the desired position, the reverse beam path, i.e. from bottom to top, was required in the printer. However, the latter is disadvantageous for the reasons mentioned above.
  • the sheet turner ST according to the invention now also overcomes this difficulty in a very simple manner by automatically turning the copy material sheets in such a way that it transfers them to the paper processor PP in the correct orientation.
