  • an externally accessible key 48 is molded onto the support 42.
  • the first separating element consists of a plastic that is sensitive to cold flow, so that the spring properties of the arms 44 are not impaired even if the slide is not fully inserted into the housing.
  • Fig. 7 it is indicated that the arm 50 of the spring assemblies 26 on its side facing the stack is treated to increase the friction with the material of the sheets. This can be done by coating with a suitable material, by roughening or in another way.
  • teeth 52 are shown in such a way that they extend against the slide extension direction and thereby hold an image, but the slide insert with the Do not hinder the remaining stack.
  • An image stop in the form of projections 56 is provided on the housing base 54 near the housing opening through which the slide moves.
  • Several ribs extend in the direction of the slide extension - three in the exemplary embodiment, which are denoted by 58.
  • On the bottom of the separator bar 36 are projections' 60 Jbeidseits of the center rib is provided as well as projections 62 outside of the outer rib 58.
  • Fig. 8 characterized is located an image Zvi ⁇ rule separator and ribs, waves deformed and thereby stiffened in the longitudinal direction (ie in the slide extension direction).
  • the function of the changer is explained below: Fig. 3 shows the initial situation.
  • the end of the stack on the separator side is pressed against the viewing window by the spring arms 50, and the separator web is located behind the steps 46, seen in the slide pull-out direction, the spring arms 44 of which are relaxed.
  • the spring arms 72 facing away from the separator web, which are provided with inclined hooks 66, likewise press the stack against the viewing window.
  • the effect on the images differs depending on whether they are braked by the inclined hooks 66 at their end facing away from the separator web or can slide away over the inclined hooks without being braked. These latter images are simply taken along by the separator web.
  • the images braked by the inclined hook on the other hand, slide down their edge facing the separator along its inclined surface, the spring arms 50 being pushed away from the window.
  • the underside of the separator 36 runs onto the slope 74 of the steps and delimits with the step a gap which is wider than an image thickness but narrower than two image thicknesses.
  • the gap is kept to measure despite possible tolerances during this image separation process.
  • the upper side of the steps 46 is provided with a rounding 76, so that line contact with the separator or the image takes place and the exact dimension of the step height and thus the gap width remains unchanged even in the event of a tilt.
  • the force component of the separator acting in the extension direction finally overcomes the braking force of the hooks 66, which - because of their inclined position - slide off all image edges except that of the bottom image. If the separator web has slid over the steps 46, there is basically a risk that the second lowest or even - 5 -

  • the entire stack is from. the ribs 58 or slide bars 34a are supported at a level which is above (ie closer to the window 22) than the lower edge of the separator. If the slide is then pulled, it transports the entire stack to the outside.
  • the support 42 has a cam 78 which is still standing and which, when the button 48 is manually pressed, is guided into a corresponding recess 80 in the separator or snaps into place, but snaps out again when the slide is pulled out due to the limited stroke of the support 42, when the slide is pushed back by the separator running onto the step 46 or is pressed back onto the cam 78 until the alternating function position is reached again.
  • the assembly is also subject to a force exerted on it by the separator in the slide extension direction during the changing function; In order to prevent the assembly from being inadvertently shifted as a result, the assembly is locked in the change position and can be unlocked manually if the entire stack is intended to be removed and the shift is to be carried out.
  • a lug 82 is provided which engages in the opposite edge of the housing and can be disengaged from it under elastic deformation.
  • the friction can be reduced by appropriate material selection or rolling friction can be provided, and / or on the spring side, friction can be increased by roughening, material selection and the like, in the exemplary embodiment teeth 52 made out of the spring material are provided , against which the separator has a recess 86 so that it does not drag along the teeth during the slide return stroke. Instead of these teeth, a special adhesive coating can also be applied.
  • the teeth are placed against the slide-out direction; on the return stroke of the slide towards the end of the changing process, the bottom image of the remaining stack does not come into contact with the teeth in a manner causing damage, above all due to the fact that it is spaced apart by means of the ribs 58 and / or the base strips 34a.
  • the clamp effect described acts in the exemplary embodiment on approximately half the slide stroke.
  • this method of capturing the isolated image could also be applied to the entire slide stroke.
  • the friction-increasing measures would then also be applied to the spring arms 72, the spring assemblies still being could rather be designed, namely in the form of a continuous band.
  • the spring arms 72 are overrun by the runners 88 formed on the base strips 34a in order to press these arms down, so that images are filled in when the slide is only partially pulled out should not be hindered, ie without getting under the springs (ie between spring arms 72 and housing base).
  • the isolated image is kept under control in another way. Its end edge, which is supported by the hook at the start of the changing process, lies in front of the projections 56 because the separator web 36 presses the image downward, supported by the action of the spring arms 50 which raise the other image edge. It should be noted that, as a rule, the pictures, if they are photo prints, are not completely flat, but are arched in an unpredictable manner.
  • Each of the holding systems preferably acts on the image at two points in order to prevent twisting. From the exemplary embodiment, e.g. be deviated by the fact that instead of the stack, the single image is transported out of the housing by the slide and / or that the image is removed on the window-side stack side instead of on the side facing away from the window.
  • Fig. 11 illustrates a variant in the design of the spring arms 72.
  • a mechanism is mounted at the free end, 'which engages after the image separation via its edge, and it increases with downward when the skid overrun the spring arms.
  • the mechanism includes a hook 92 which is slidably attached to the spring arm. Its position is indicated by dashed lines during the first phase of the change process. When the runner comes up, it is moved to the position shown in solid lines, where it snaps over the free edge of the image and holds it there.
  • the spring arm 72 (not shown here) carries a rail 94 on which a stop step 95 is formed.
  • a two-armed lever 100 is pivoted about a pin 98, which lever pivots the lever in the direction of the arrow from the residual stack 102 pushed by means of the separator.
  • a cranked handlebar 104 is articulated, which extends counter to the direction of movement of the remaining stack 102 and is protected behind the step 96 in the rest position by lever 100, facing the single sheet or frame 106 with a cutting edge 108.
  • FIG. 13 to 17 illustrate variants of the holding device which holds the single sheet in the housing. Notwithstanding guide for the first training a pair of toothed 120 slides is not held zelblatt by spring bias in engagement with the Ein ⁇ here, but the separator bar 36 has projections 122 that the single sheet at the slide extract (Fig. ⁇ 13) in engagement tense with teeth; It can be seen that the toothed rails 124 take over the function of the ribs 56 from the first exemplary embodiment. 14 shows that the rails 124 can be withdrawn behind protective strips 126, for example in order to be able to remove the entire stack. For this purpose, the two rails 124 are connected to one another by a cross piece 128 to form a one-piece counter element which - cf.

Abstract

Un échangeur d'images comprend un logement avec une fenêtre et un coulisseau qui regroupe cycliquement, lorsqu'il est actionné, une pile d'images placées dans l'échangeur. Pour simplifier sa construction et rendre plus aisé l'échange des images, le processus de séparation de chaque image, qui se fait sous une forte tension initiale de ressort, se limite à une courte course partielle. Pendant le reste de la course d'échange, la feuille séparée se raidit dans le sens du transport en éloignant le reste de la pile de la fente de séparation, étant elle-même retenue par des butées. On peut débrancher la fonction d'échange en déplaçant la fente de séparation.
