Description

10 15 20 25 30 35 40 7309728-4 2 institution that has produced the finished photographs.

The photographs delivered by copyists do not have only different image formats, of which the final formats of 9 x 9 cm ( neighbors 8.9 x 8.9 cm), 9 x 11.5 cm, 9 x ll, 7 cm, and 9 X l3 cm are the most common, but they also have within these nominal formed rather large dimensional tolerances; these can amount to 5 mm and is partly due to the fact that the photographs are given the final format in various ways, for example by punching, cutting, cutting from paper rolls, etc. Furthermore, the photographs can be thickness varies quite greatly depending on the brand. Although the thickness of the photographs is generally between 0.25 and 0.3 mm thus, even larger and smaller thicknesses can occur.

In addition, the photographs can have right-angled or round corners, and depending on how the image is given the final format, the image edges may be designed in different ways, and they may possibly exhibit degrees from the cut.

Finally, the different photographs can be arched to varying degrees and in different directions, this due to the so-called photo paper in in fact, it does not consist of paper but of a paper-like one plastic carrier, which is provided with a large number of different layers, which are embedded or embedded in gelatin. Gelatin is a natural product and therefore varies greatly with respect to, on their properties. In particular, gelatin is highly hygroscopic, while the plastic carrier is hygroscopic to a much lower degree, and depending on the humidity, different strengths arise stresses between the plastic carrier and the gelatin layers, and these tensions cause the photographs to bend differently.

The bending is also affected by the said chemical layers, which are embedded in the gelatin and consist of at least one light-protective layer, a filter layer, a fixing layer, a protective layer and three layers and possibly additional layers, which again depends on which manufacturer supplies the photo paper and which special chemical processes used for the development.

If you consider here, that there are at least five major manufacturers of photo papers, namely Kodak, Agfa, Fuji, 3M and Sakura, which each produces different photo papers, and that there are a number of copying establishments, which process the photographs, in in particular, gives them the final format, with devices of widely differing kind, then it also becomes obvious, that the main problem when it to achieve a reliably functioning photo viewing 10 15 20 25 30 35 40 78097284) exchanger lies in the fact that the photographs uploaded in it are different, even if they have the same nominal format. Such a photo- view exchangers must therefore meet the requirement to function equally reliable for all these different photographs. In particular, should it meets the following requirements or at least some of the following requirement. (1) strongly separated from each other, they must all be able to be exchanged equally reliably. (2) must be done with the same certainty despite the differences of the photographs. (3) the end of the bar (top or bottom of the bar) must Even if the photographs in one and the same bar differ Transport away from the stack of the various photographs The reintroduction of a separate photograph to the other happen reliably. (4) The photographs should be pressed against a viewing disc, so that they can be viewed in a flat state. (5) the changer and during its operation no photographs are taken While viewing a photo in photo viewing fall out, this regardless of the position in which the exchanger is held and maneuvered. (6) in any position, for example even if the viewer is lying down on the back- (7) the exchanger individually or in a stack. (8) preferably, thus regardless of whether it is completely filled with It should be possible to operate the photo viewing exchanger It must be possible to insert or remove the photographs The exchanger must work with any degree of filling for example 25 photographs or if it contains only two or three pictures. (9) otherwise the photographs must not be damaged, compressed or bumped The exchanger must be manoeuvrable, and speci- together, scratched or otherwise deteriorated by the mechanism of the exchanger would be incompletely affected. (10) If desired, the photographs may also be viewed durable, which requires that they can be set up or suspended by means of the exchanger. (ll) The exchanger should be stackable in regular or suitable form. (12) The changer should be "pocket friendly" so that the photographs together with the exchanger can be put in a pocket, for example one suit pocket or handbag; for this purpose the exchanger should be flat as far as possible, rounded at the corners and 10 15 20 25 30 35 40 psig 78097284! friendly designed. (13) Furthermore, it should be possible to manufacture the exchanger easily and favorable, and more precisely it should, as far as possible be able to be manufactured and assembled automatically; its parts should be suitable for the production of plastics by injection molding. (14) The shift mechanism must function so reliably that it always takes out and returns to the bar just one photograph and thus never with correct and complete operation shifts two photographs at the same time or no photograph changes at all. (15) the exchanger should protect the photographs against finger sweat and against dust. (16) The exchanger must be compact and must therefore have: a small space requirement and a large part of its volume, if possible most of the volume should be occupied by the photographs themselves. (17) As far as possible, the entire image area of the currently exposed photograph is visible, and so led should no or only a very small part of the image area obscured. (18) It should be possible to indicate by endorsement the the direction. (19) The insertion of the photographs in the changer must also can be done mechanically, especially with vending machines that implement the insertion of the photographs, the closing of the exchanger and a function check. _ (20) The mechanism of the exchanger shall allow different embodiments, whereby in one embodiment it should be possible to take out the graphs from the bar at the top and return them at the bottom, while in another embodiment it should be possible to take out the graphs at the bottom from the bar and return them at the top; possibly there must be a mechanism by which it is possible to withdraw a photograph inside the bar, for example, pull it out of the bar top image not from above but from its underside.

The requirements set out above with respect to a photographic exchangers also apply to other blade or card-shaped devices. targets, hereinafter referred to briefly as "leaves", for example for cards with cooking recipes, orienteering cards for ski slopes, hiking trails or similar and register cards for small register, to name just a few examples. In addition, they apply the above requirements at least in part also for card changers 10 15 20 25 30 35 40 780972844 on which there are invisible records; it is, for example, with an exchanger of the kind mentioned in the introduction present magnetic cards with language lessons for a simple, example show battery-powered magnetic head sensor, which can be fixed on the shift mechanism. Although the invention may preferably be applied to thus, it does not refer exclusively to a photo viewer changer, but it generally relates to a device for alternating exposure of individual leaves in a leaf stack. More specifically, by invention, a device of this kind is provided with which at least some and preferably all of the above requirements are met. and the disadvantages of the prior art overcome.

The device according to the invention, which is built on the routinely indicated method, is characterized in that at least at the part adjacent to the blade edge one end leaf in the leaf stack forms an acute angle with it facing the stack of leaves facing the surface of this end blade and there, at least in one or more places and preferably along the entire leaf edge, has an extension, which extends at least to the edge of the leaf edge lying on the outside of the stack, and preferably extending outwardly from the stack past this edge.

With this design, in particular, a secure separation is achieved of for each occasion a single leaf from the leaf stack without there is a risk that either no leaf is separated from it at all the stack or several leaves are separated from the stack simultaneously. This device works reliably even if the blades have relative large surface dimensions and thickness tolerances.

In this case, the device according to the invention can be so designed, that on the outer side of the end blade is adjacent to the extension at a distance from this an arbitration stop, which is so arranged or adjustable, that the projection of the abutment surface is parallel to it in the area of the separating stop and the extension lying surface of the end blade is inside the extension, with it within the area between the arbitration grant and the extension there is an arbitration room, in which the end blade can bend in with its edge and thereby separate from the nearby leaf.

Furthermore, the device according to the invention can be so constructed, that the distance between the extension and the end facing it of the abutment surface is small in relation to that at right angles to 10 15 20 25 30 35 40 780972844 leaf edge abutment surface lying leaf length or leaf width or that it is between the removed blade and the closing blade transmitted friction force is small in proportion to it for bending the blade edges at the blade edge abutment surface required bending force for the bending of the blade edge in the separation room. _ Preferably, the device is so designed that the extension passes into a socket opening, in particular into a socket slot, whose width is slightly greater than the thickness of a leaf and whose length is slightly greater than the length of those parallel to it extending leaf edges.

In the case of a simplified but nevertheless reliably functioning in the area of or instead of the separation there is a free access, through which a pressure, in fingerprint, can be applied to it at the slot located end blade, whereby the blade can be pushed out of the the slit under the influence of the pressure component lying in the blade plane. ten.l The device according to the invention may in addition have a blade insert. guide device for inserting a blade into the stack, in particular for reinserting a blade removed from the stack. Thereby can the device be of such a nature that the blade edge abutment surface at least at the part adjacent to the blade edge of the other the end blade in the leaf stack, at one or more places and treads along the entire edge of the leaf, has an extension, which extends to the edge of the pile lying off this leaf edge and preferably extends outwards from the leaf the pile past this stripe, it adjacent to this stripe and the adjacent this horizontal outside of the leaf stack there is an insertion space, through which the edge of a leaf entering the stack can inserted into the stack without disturbance from the edges of those in the stack existing leaves. The device can in this case be so designed that on the outer side of the other end blade is adjacent to that one existing extension at a distance from this at least one insertion stop, which is so arranged and adjustable that the projection of its abutment surface parallel to that in the area between the insertion the abutment and the surface adjacent to this extension of the other end blade is inside this extension. At this design is preferably the distance between the adjacent the other end blade existing extension and the one against it 10 15 20 25 30 35 40 780972841 turn the end of the abutment surface of the insertion abutment small in relation to to it lying at right angles to the blade edge abutment surface leaf length or leaf width. In particular, the structure is such, that the extension adjacent to a second end blade passes in an insertion opening, in particular in an insertion slot, the width is slightly greater than the thickness of a leaf and its length is slightly greater than the length of those parallel to the same running leaf edges.

The blade edge abutment surface preferably forms in the area of its elongation facing the slot an acute angle with that from the stack facing the surface of the other end blade. Preferably available further on the side of the leaf stack facing away from the leaf edge the abutment surface, a counter-blade edge abutment surface, which forms a acute angle with the inwardly facing surface of the stack on it at insertion slot lying leaf.

The above-mentioned acute angles can be between 300 and 600 preferably between 450 and 600, with it being particularly suitable that they are between 400 and 450, and preferably they are 420.

The blade edge abutment surface with its elongation and / or counter- the blade edge abutment surface is preferably flat, and in particular the blade edge abutment surface and the counter-blade edge abutment surface are mentally to each other, so that the leaves in the stack at two opposite edges are arranged between two parallel abutment surfaces.

For inserting and removing the stack of leaves, the counter-leaf the edge abutment surface be arranged on a rotatable building part, preferably a substantially wedge-shaped component, which is pivotable about one with the blade edges parallel to the axis and whose counter-blade edge the bearing surface set preferably forms another side wall a leaf accommodating house. Removing the leaf stack is facilitated if the wedge-shaped building part at its pointed end has a wonder the leaf stack gripping nose, which during the swing lifts up the leaf the bar from normal mode.

Furthermore, there may be a snap device for snapping the wedge-shaped component in its normal position. In a preferred embodiment, the snap device comprises on the one hand a flat surface, which thirdly, a surface at the bottom of a leaf stack is a housing, secondly, one arranged on the opposite side of the rotatable building part counter-plane surface, which in the direction of rotation opposite to the the oscillation of the part from its normal position changes to an arcuate surface, whose radius of curvature decreases to a value equal to the distance between 10 15 20 25 30 35 40 78997284; the axis of rotation of the component and the flat surface. The counter-plane surface can i the direction in which the component swings from its normal position, pass-in the said nose.

In addition, the rotatable component may have one or more jump, which in the normal position of the building component takes over the adjacent lying edge on the leaf stack.

The separating stop can be made as a roll or roller, in in particular as a rubber roller or rubber roller, in displacement devices for displacement of the one located at the removal slot the blade, or such a roller or roller may be provided side of one or more dividers only for the displacement of the said blade. In a particularly simple embodiment, the roller can or the roller be accessible for manual twisting at its from leaf stack facing side. In order for the roller or roller to be able to adapted to different degrees of filling for the use according to the invention. the arrangement is parallel to the removal slot shoulder line perpendicular or oblique to the leaf stack and is to and with when emptied device movable up to the bearing surface of the blades.

The material of the roll or roller is so selected that the friction the coefficient between its surface and the leaf facing it the side is large in relation to the coefficient of friction between adjacent leaves. Incidentally, this may also be the case with others, later said rollers or rollers.

The roll or roller is preferably mounted on a jumper, which is pivotable about a parallel running with the socket slot axis of rotation and arranged retractable in the bottom of a blade stack of accommodating houses. This jumper not only makes it possible the above-mentioned adaptation of the roll or roller to the filling the degree of the device according to the invention, but it can also serve to erect the leaf stack accommodating the house, so that the device according to the invention can be set up as an image frame on a table. In order for it to be set up both in lying as in standing position is the one as a lowering element serving jumper pivotable to and snap-in in a first and a second position, the one in the first position being in the apex angle and in the second position is at right angles to the stack of leaves.

The device according to the invention can in particular be designed so that there is one or more dividers at the support surface for the stack of leaves and one or more insertion stops on an support surface, which is arranged on the support surface opposite the side 10 15 20 25 30 35 40 780972844 of the stack of leaves, or vice versa.

The support surface for the leaf stack can in particular be arranged on the inside of the substantially transparent lid of the housing or in mainly formed by this inside, while the counter-support surface is arranged on the bottom of the house or is mainly formed by it.

It is preferred that the counter-support surface is arranged on one pressing plate, which resiliently presses the stack of leaves against it layout area. If there is for the pressing of the pressing plate a conical spiral arranged on the side of the plate facing away from the leaf stack spring, a special space-saving construction is obtained, as the coil spring can be compressed to its material thickness.

However, it is also possible to allow the counter-support surface to be formed of one, two or more rollers or rollers, in particular rubber rollers or rubber rollers, against which the leaf stack resiliently presses the blade stack its support surface. The counter-support surface can also be formed by a spring plate of spring steel or resilient plastic, the above-mentioned The conical coil spring is preferably replaced by one or more in one piece with the spring plate made spring parts, in particular resilient tongues, and wherein further the insertion stop is one resilient part, which is also preferably made in one piece with the spring plate. This resilient part can be a spring tongue and have greater elastic flexibility than the rest of the spring plate, which can be achieved, for example, by having a smaller thickness than the rest of the spring plate.

The arbitration grants and / or the introduction grants can be advantageous be resilient.

For semi-automatic or fully automatic reintroduction of an output leaf, the device according to the invention has a slide which is movable perpendicular to the removal slot to such an extent that it constantly occupying it for each occasion out of the socket slot the next leaflet on the pick-up transport surfaces, it further having insertion transport surfaces for inserting the blade in and for its insertion into the insertion slot. Sliden is stored and controlled for reciprocating movement on the blade stacker device or on one of these formed or on the same attached house. The slide has a frame, which extends along in the direction of movement of the slide extending side edges of the leaf stack.

In the area of the side edges of the removed blade it is on sliding springs, especially leaf springs, which extend in the direction of movement of the slide and which presses it for each occasion 10 15 20 25 30 35 40 '? 8Û9728 ~ l | 10 blade coming out of the removal slot to the plane of insertion the transport surfaces on the slide. These springs arranged on the slide are in the vicinity of the withdrawal slot designed as an arbitration stop, in such a way that they form an arcuate projection which they constitute a resilient arbitration grant. These springs are controlled in each recess, which is included in a confinement area for slot, which boundary surface is in turn arranged on the leaf stack holder device or a leaf stack accommodating housing.

The removal slot and / or the insertion slot can be arranged those between a first socket slot arranged on the housing ~ resp. insertion slot limiting member and a second disposed on the slide outlet slot resp. insertion slot limiting member. Closer determined, the first socket slot resp. insertion slot the limiting part has the blade edge abutment surface and for this purpose be wedge-shaped. The second socket slot limiting the part may be a plate arranged on the slide, in particular a visible cover plate, which forms the lid of the housing when the slide is not drawn, while the second insertion slot limiting member can be formed of one or more slides extending in the direction of movement of the slide parts, or vice versa.

In a particularly preferred embodiment, there is one on the slide gripper, which carries the end located at the removal slot the blade of the blade stack.-The gripper can be designed on widely spaced way. It may, for example, have a suction device which is connected to one of the sheath movement maneuverable and controllable suction pump. A special However, a particularly simple construction is obtained if the gripper is carried as a protrusion, which engages with it in the area of the trailing edge of the counter-blade edge abutment surface on the the taking slot lying end blade of the stack.

For pre-sorting or differentiation of the leaf to be brought from the nearest inside blade has the blade edge abutment surface in the area of the trailing edge of the the end blade lying two stepped ledges with one step height that is slightly greater than the thickness of a leaf. The stair- the shaped ledges may be arranged on the above-mentioned, rotatable, in particular the wedge-shaped component.

The displacement device for displacing the blade which to be taken out and / or introduced can also be so structured that it has one or more friction rollers, which attack the wide ones the leaf edges lying on the side of the removal or insertion slot. 21 .. 10 15 20 25 30 35 40 780972841 ll The leaf stack accommodating housing has a folding or slidable lid or top piece, which is complete or at least predominantly transparent to allow consideration and / or reading the leaves. This house can be equipped with one or several stacking devices for stacking several similar houses, known per se stacking devices of white different types can be used. Particularly simple and advantageous have however, it turned out that the house is provided with stacking tracks and stacking projections.

In certain embodiments of the device according to the invention the slide is designed so that the lid of the housing is attached to the slide and together with this extendable so far out of the house at one side of this parallel to the leaf surfaces, that it in its most elongated location is still left in the house and with a predetermined length grips the stack of leaves.

This overall part serves in one of the preferred embodiments the forms as a basis for a so-called insertion appropriations, the function of which is discussed in more detail above. At the same time, the overall part serves to prevent the stack of leaves from falling out on one side when the slide is most pulled out of the house and the opening of the house is turn downwards, which can occur for example if the leaves, e.g. photographs, viewed by a person lying on his back. In those cases then the overall part should not have only the former of the two functions listed above, are located on the opposite slide the side wall one or more leaf stacks overall projections, the stack of leaves is effectively secured against the outcome only if it seized from two opposite sides. The latter side wall can also self grab over the stack of leaves. Although in principle it is preferable to slide itself in its own most extended position grips the leaf stack at the side there the slide is extendable out of the housing, because the slide in general, to permanently associated with the house, in any case should not be completely extendable from the house, it is in principle also possible to make the slide extendable so much that it at its most extended position no longer engages the blade stack, leaving the blade the stack at the elongated slide instead is overlaid by the housing itself or of one or more projections arranged on the housing from that side of the housing where the slide is extendable.

In all these cases arise through the overall parts problems removing the stack of leaves from the housing or inserting a leaf 10 15 20 25 30 35 40 7879972844 12 stack in an empty house, this even if the slide is extended so far as possible out of the house.

Through a further development explained in more detail below, the the device according to the invention is designed so that at maximum elongation slide, despite the overall parts, a leaf stack can be easily removed out or put into the house.

This is achieved by putting the slide opposite the side wall on the housing is mounted on an additional slide, which is attached to the housing of a locking device and when affected it is extendable housing slightly longer than the predetermined length by which the blade the stack is extended on the slide side when the slide is maximally extended.

In this way, the blade stack on the slide side can be lifted out and removed or placed in the house past the overall part, whereby in the latter case it is pushed below those on that slide standing housing side, thus preferably on the additional slide, arranged the overall parts.

The locking device can be designed so that it has one on the additional slide is mounted and in a locking stop on the housing engaging retaining latch. This retaining latch can be attached on a tongue, more precisely so that it by swinging of the tongue can be brought out of engagement with the locking stop on the housing. Design the operation and operation of a barrier designed in this way order becomes particularly simple if the retaining latch is resilient, in particular through the tongue's own elasticity, is kept in engagement with the the stop on the housing, so that it comes out of engagement with the locking stop by a pressure directed into the housing against the tongue.

This device can further be designed so that a stack of leaves such as shall be taken out at its release automatically also lifted out so much out of the house, that one can seize it without difficulty. This can is achieved by facing the side of the tongue towards the stack of leaves at the latter oscillation to remove the retaining latch from its inner grip with the locking stop engages with the blade stack and is pivotable so far inwards in the housing, that the leaf stack preferably completely pushed out of the housing at one side.

To the leaf stack when pulling it out further the slide must be pulled forward at the same time under the slide side, overall part, the tongue can at the place where it enters engagement with the blade stack have an engagement surface with high friction, and this engaging surface with high friction can be formed by one on the tongue applied friction element, in particular a rubber blade. Such a 10 15 20 25 30 35 40 7899728-4 13 engagement surface with high friction also has the purpose of i also hold its position pressed against the underside of the leaf stack the blade on the stack of blades that would otherwise be pulled out of the slide elements when pulling out the slide. These gripping elements can be for example_grip tongues or of material with high friction freewheel rollers or freewheel rollers, the rotation of which is inhibited when removing a leaf from the stack, so that they pass through it between the same and the blade present frictional action protrudes the blade to be removed from the housing. The great friction that leads removal of leaves from the leaf stack is practiced on this leaf by them gripping elements can be overcome by a suitable heavy pressing of the engaging surface on the tongue with great friction against the leaf stack, so that the grippers slide along it with rather large withheld blade, which would otherwise be included in the the traction of the slide.

In order for the tongue to be affected better and safer, can it have a finger grip depression, through which the pressure for swinging of the tongue and for gripping the stack of leaves with the tongue exercised. Since the tongue is generally affected from the bottom of the house, while the user has the top of the house in his field of view and thus not at all looking at what place he must influence tongue, it is through this depression easy for the user to feel the tongue to affect it, and at the same time an accidental impact on the tongue is avoided, as the user without difficulty can prevent his finger from entering the when he should not affect the tongue; he notices, of course immediately if his finger should inadvertently fall into the area of the deepening.

Since the tongue is suitably arranged inside a gripping surface, which serves to hold the housing during operation of the slide, it is very important to be able to automatically distinguish between the gripping surface and the adjacent finger grip recess by finger feel, especially if the finger grip depression is arranged immediately next to the gripping surface, which is very practical for handling reasons, as the user in such a case at transition from changing the blades to removing the stack of leaves only need to move his finger, which rests on the gripping surface next to it the finger grip depression, a very short distance inwards on the housing bottom surface.

For the leaf stack to be pushed out on the right side of 10 15 20 25 30 35 40 780972842 14 the house, i.e. on the side where it has been pulled out by the tongue the overall part of the slide or possibly on the housing at the operation of the additional slide, the tongue can with its free end, on which the engaging surface with which it is pressed against the blade the stack is arranged to extend in the direction of the slide past the middle of the house. In this way, the pressure exerted with the tongue acts on the side of the leaf stack facing it for rearrangement the leaves in the leaf stack serving the slide.

A particularly simple construction can be obtained by the tongue arranged in a preferably also tongue-shaped guide part on the further slide, which guide part is displaceable in it further direction of movement of the slide along guide surfaces in the housing, especially at the bottom of the house. This control part and control the surfaces can thereby already alone be sufficient as a guide for the additional slide, for which some other guides thus does not need to be arranged.

Finally, there is suitably a stop on the control part, which serves to limit the movement of the additional slide out of the house by cooperating with a counter-stop on the house, in especially on the bottom of the house.

It should be emphasized here that the further development described above is useful in principle in all cases where the device has a leaf stack accommodating housing, the bottom of which is parallel to the leaf the surfaces and whose side walls enclose the leaf stack at the sides, and where furthermore the upper part or lid of the housing is mounted on a slide and at one side of the housing extendable parallel to the blade surfaces so far out of the house along with the slide, that it at its maximum extended position still remains on the house and grips over the stack of a predetermined length or the stack of leaves when pulled out slide is overlaid by a predetermined length from the housing side, from which slide is extendable, finally at that slide opposite the house wall preferably there is one or more leaf stacks overall protrusions and / or this side wall itself engages the blade.

In principle, further development can be successfully be used in all devices which, on two opposite sides, hold a ' leaf stack or a single leaf with overall protrusions, or the like, of which a protrusion, an edge or the like is stationary, while the other according to the invention is applied to a sheath, which corresponds to the sheath which has previously been 10 15 20 25 30 35 40 7809728-4 15 mentioned "additional slide".

This device further has a support surface 3, which is parallel to the blade surfaces and to which the leaf stack l can be pressed. The pressing of the leaf stack l against the support surface 3 takes place under the influence of the pressure from a drive roller 4, which is rotatably mounted on a bracket made of metal or plastic 5, which in turn is pivotable about an axis 6. This drive roller is located in a recess 7 in the bottom 8 of the housing and can be by being pressed by hand against the leaf stack 1, whereby it can be inserted in the interior of the housing 2, so that it can be adapted to a varying degree of filling of the device, i.e. to a varying thickness or height of the leaf stack 1. The drive roller 4 also has a function to displace the bottom blade in the stack of leaves 1 in order to taking of this sheet, and for this only the user is needed with one or more fingers, rotate the roller in the direction of an arrow 9 direction and at the same time press the roller against the leaf stack l.

In an even simpler embodiment, even this drive can roller is omitted, whereby the recess 7 is made so large that the user with the finger can exert a pressure on the leaf apple l through the recess and thereby simultaneously transmitting a force directed to the right in Fig. 1 the bottom blade, so that it is displaced by the the slot 10. For this purpose, the recess 7 can, for example, be formed by a slit in the part of the bottom ll of the housing adjacent to the outlet ning slot 10. This slightly more than finger-width slot, which is not shown in Fig. 1, extends in the longitudinal direction of the housing. 10 15 20 25 30 35 40 7809728-4 19 The device in Fig. 1 has a blade removal device for taking a leaf from the leaf stack 1, and this leaf removal device has a blade edge abutment surface at one side of the blade stack 1. The blade edge abutment surface ll forms at least at it part adjacent to the blade edge l2 on the lower end blade l3 an acute angle N. with the surface facing the stack of leaves on it end leaves. Preferably, the acute angle W is the same across the entire blade stack height, and the blade edge abutment surface ll is thus preferably a plane, obliquely inclined to the transverse direction of the leaf stack 1, as shown in Fig. 1.

Below the blade edge 12 of the lower end blade 13, the blade the edge abutment surface 11 in the recess slot 10, the width of which is slightly greater than the thickness of a leaf and whose length is slightly greater than the length of the edges extending parallel to the slot the leaves in the leaf stack 1. Slightly above the leaf edge 14 at the top the end blade l5 in the blade stack 1 passes over the blade edge abutment surface ll in an insertion slot 16, through which one passes through the removal slot removed leaf can be returned to leaf stack 1.

An important feature of the device according to the invention, which has been touched on briefly above and in the following will is explained in more detail with reference to Figs. 2a - 2c, lies in the fact that the blade edge abutment surface ll not only covers the edge 35 thereof second lowest blade 33 but has an extension 18, which extends at least to the one facing away from the stack, i.e. bottom edge 12a on the edge 12 of the lower end blade 13, so that this blade normally, i.e. when it is not affected by any displacement, can not go out through the socket slot 10. Preferably shoots however, the extension 18 in the manner shown in Fig. 1 from the leaf stack 1 past this bottom edge l2a on the edge l2. At that place adjacent to the extension 18 and the adjacent the underside of the leaf stack l there is a dividing space l9, in which the edge 12 of the lower end blade 13 can be separated from it parallel to the same lying edge 35 on the adjacent, next to the bottom leaf, as explained in more detail below.

Furthermore, there is an appropriation 20, which is referred to here as the kind because it supports the above-mentioned separation of the leaf edge 12 from the leaf stack 1. The separating stop 20 is so used arranged, that it engages the lower end blade of one place located at a predetermined distance A from the slot 10. This distance A is small in relation to the distance B 10 15 20 25 30 35 40 7809728-4 20 between the blade edge l2 adjacent to the removal slot and the opposite blade edge 21 on the lower end blade 13, i.e. more generally in relation to the dimension of the leaves in the stack has in the direction in which the blades must be displaced at the selection.

The separating stop 20 is further arranged so that it with leaf blades the surfaces parallel to the projection 22 (see Fig. 2a) of the abutment surface 23 lies within the extension 18 of the blade edge abutment surface 11. Üäri- by ensuring that the lower end blade 13 does not by itself, i.e. without the influence of a displacement force, can move through the removal slot 10, this regardless of in which position the housing 2 currently being held. Also in the area of the upper, located at the insertion slot on the blade stack 1, the blade edge abutment surface 11 has an elongation 24, which before it passes into the insertion slot 16 extends at least to the outer, in Fig. 1 thus the upper edge of the leaf the edge 14 of the second end blade 15, so that also the blade edge 14 on the top leaf is covered and does not prevent the insertion of one blade through the insertion slot 16. The extension 24 is preferably so large that it protrudes past the upper edge_l4a of the leaf- edge 14. Adjacent to this part of the extension 24 and adjacent to it the extension adjacent the upper side of the end blade 15 has an inner guide space 25, through which the edge 26 (see Fig. 2c) of a genome the insertion slot 16 incoming blade 27 can be inserted into the stack 1 without being disturbed by the edges of the leaves already present in it.

In order that also the blade edge 14 on the upper end blade 15 should held securely within the area of the blade edge abutment surface ll extension 24 and for the insertion of the blade 27 to be supported, there is an appropriation 28, which here is called an introduction appropriation. This insertion stop 28 engages the end blade 15 in one place located at a predetermined distance C from the insertion slot 16, which distance is small in relation to the distance D between the blade edge 14 adjacent to the insertion slot and the latter opposite leaf edge l5a. More generally, the distance D is equal to it dimension that the leaves in the leaf stack 1 have in the direction in which the leaves must be displaced when removed from the stack of leaves and at insertion into the leaf stack.

The stop 28 is arranged so that it is parallel to the blade surfaces projection 29 (see Fig. 2c) of the abutment surface of the insertion stop 28 28a is within the extension 24 located at the insertion slot 10 l5 20 25 30 35 40 78097284; 21 of the blade edge abutment surface ll. This ensures that the the edge 14 of the upper end blade 15 is not in any position of the housing 2 can enter the insertion slot 16, this is not even due to a pressure with which the leaf stack 1 is loaded from below, for example view of the drive roller 4.

The blade edge abutment surface ll forms at least in the area of the extension 24 located at the insertion slot is a pointed one angle, G with it outwards, ie. upward facing surface of the end blade 15.

This angle is in the present case equal to the angle CL, since the blade edge abutment surface ll and its extensions are an unbroken one flat surface. In principle, however, it is not necessary that the angle / 6 M.

The acute angle äiresp. ; 2 300 and 600, preferably between 450 and 600, and in particular is angular range 400 - 459 to be preferred. In a very well-functioning is equal to the angle is generally between Embodiments of the device according to the invention are those acute angles LX and ß 420.

On the side of the leaf stack 1 facing away from the edge bearing the surface 11 is a counter-blade abutment surface 30, which forms one acute angle ¿f with the inwardly facing surface of the stack on the upper the end blade l5 and whose distance from the blade edge abutment surface ll is slightly larger than the length of the blades in the direction of displacement. As already expressed by its name constitutes counter-blade edge the abutment surface 30 is a counter surface to the blade edge abutment surface 11.

These two surfaces 11 and 30 are therefore preferably complementary to each other, so that the counter-blade edge abutment surface 30 in the embodiment the shape according to Fig. 1 is also flat and the acute angle / 3.

The general principle of the invention is based on Ä 'is equal to the angle 06 resp. the separation of a leaf from a leaf stack and the principle of the insertion of a leaf into a leaf stack will now be explained more specifically with reference to Figs. 2a - 2c in connection with The embodiment of the embodiment of a device shown in Fig. 1 photo viewing changer.

To begin with, reference is made to Figs. Za and 2b. In Fig. 2a the lower end blade 13 is shown in its rest position, i.e. in the stand that it normally has in the stack before it is loaded with a mot the removal slot l0 directed displacement force. In this position lies its blade edge 12 adjacent to the removal slot in front of the blade the extension of the edge abutment surface ll 18. It is thereby retained by 10 l5 20 25 30 35 40 1809723-4 22 stop 20. If now the drive roller consisting of rubber, for example 4 in the area of the recess 7 is pressed against the underside of the lower end blade 13 and at the same time rotated in the direction marked by an arrow 31 displacement, a displacing force acts on the lower end blade 13 in the direction marked by an arrow 32, so that the blade edge 12 pressed against the extension of the blade edge abutment surface ll 18. Then it lower end blade l3 of the leaf stack 1 lying immediately above leaves, of which only the two nearest leaves 33 and 34 are shown, prevented from folding upwards in the area of the blade edge 12, the blade 13 bends into the separating space 19, and by it off the displacement force symbolized by the arrow 32 is pressed to the right in Fig. 2a, it finally enters the socket slot 10, from which it goes out when the drive roller 4 is further actuated on the above described manner. ' The deflection of the blade edge 12 in the separating space 19 and its movement into the withdrawal slot 10 is supported by the slope (angle GL) of the blade edge abutment surface ll, which to some extent acts as a surface or deflection surface, which leads or guides the blade edge l2 in such a way that it moves into the separation space 19 and 10. It should be mentioned here that the blade edge abutment the inclination of the surface 11 in the direction of the leaf stack is exactly the opposite, whereby the blade edge 12 is thus prevented from folding inwards towards the stack, thus upwards, not only by those above the leaves but also through the slope of the leaf edge abutment surface.

It should be borne in mind that the frictional force, as in the displacement of the lower end blade 13 acts between the latter and the nearest above the blade 33 and which causes a displacement of the end the blade l3 in the direction of the blade edge abutment surface 11, is smaller than the friction and deflection force that would need to be applied to it the leading edge 35 of the blade 33 to guide in this edge as well in the separating chamber 19 and the removal slot 10, whereby the prevent two blades from entering the inner entrance at the same time to the socket slot 10. Due to this, the distance A is between leaf edge contact surface resp. against this abutting blade edge l2 and the leading edge of the cut-out direction in the pull-out direction of the blades. the stop 20 is physically chosen so that it is between one on the one hand the blade 13 to be removed and on the other hand the one therefor the frictional force transmitted by the connecting blade 33 is small in to the one for deflecting the blade edges during abutment the surface ll required bending force. 10 15 20 25 30 35 40 78097284; 23 The mentioned power conditions are ensured above all by selecting the angle of inclination of the blade edge abutment surface ll, so that guided the acute angle you in such a way that it lies within the areas indicated above, and in addition by the coefficient between the surface of the drive roller 4 and the underside thereof lower end blade 13 thanks to the appropriate choice of material in the surface of the roller 4 is substantially larger than the coefficient of friction between facing the facing surfaces of blades 13 and 33.

Then these power relations are effective regardless of whether blade 33, against which the blade 13 to be removed abuts, is slightly ' shorter or longer than or as long as the blade 13, comes it does not depend on the above blade 33 at the beginning of the displacement movement due to the frictional forces between them both blades come into contact with the blade edge abutment surface ll with its edge 35 at the same time as or earlier or later than the edge 12, for the force transmitted to the blade 33 due to the friction is not due to the above conditions sufficient to cause the blade edge 35 to bend downward.

It is, of course, most favorable that the blade edge 12 strikes earlier against the blade edge abutment surface ll, since it then in the area of the the transition of the stroke 20 to the separating space 19, thus in the area of the bend 13a (see Fig. Zb) which occurs when the blade edge 12 enters the separation chamber 19, the blade 33 pushes upwards. Slightly smaller favorable is the case when both blade edges 12 and 35 are at the same time arrives at the blade edge abutment surface ll, as the bend l3a then does not yet exist. In this case, however, the leaf edge appears 12 to some extent as "abutment" which counteracts deflection of the blade edge 35 in the separation room l9. This effect occurs if also in less degree, even about the blade edge 35 earlier than the blade edge 12 hits the blade edge abutment surface ll. The re-insertion of a blade 27 into the blade stack 1 will now be is explained in more detail with special reference to Fig. 2c.

In order that the blade 37 without hindrance of the edge 14 on it at the top of the blade 15 lying on the stack 1 must be able to be pushed in on the upper side of the stack, there is the already mentioned insertion space 25, which is formed of the insertion stop 28 in conjunction with the extension 24 of the the edge bearing surface ll. The insertion stop 28 holds or presses namely down the nearest leaf 15 before the guide of the blade 27 (see Fig. 2aL so that the edge 14 of this blade 15 is clearly lower than the insertion slot 16. Of an oblique surface 36 on 10 15 20 25 30 35 40 78097284 » 24 the side of the stop 28 facing the insertion slot is diverted front edge 26 of the blade 27 after insertion into the insertion slot 16 downwards, i.e. against the stack, and the leading blade edge 26 can without to meet any major resistance slide along the top of the top the end blade 15 to the left in Fig. 2c until it enters the area of counter-blade edge abutment surface 30, when the blade 27 is fully inserted brought in the stack.

It should be emphasized here in particular, that through the slope (angle / 6) of the extension 24 prevents the insertion of the blade 27 is disturbed by the edge 14 even if the edge 26 of the blade 27 comes in engagement with the blade 15 in the vicinity of the abutment surface 30 and exemplary due to dimensional tolerances, the blade 15 shifts slightly in the direction of the blade edge abutment surface 30. Namely, the angle 6 6 is so selected in conjunction with the length of the extension 24, that the blade edge 14 even if the blade 15 has its within the dimensional tolerance the minimum length of the rations can be displaced or bent upwards in the area of the insertion slot. ' Finally, with reference to the insertion space, it should be noted, that this enables the insertion of a blade 27 in all positions and degrees of filling of the housing 2. This reintroduction is carried out for hand in the simple embodiment according to Fig. 1, when this embodiment form is created for the purpose of setting as simple as possible and without special mechanically functioning device available.

The removal slot 10 can run with a bend or weak slope upwards, ie. form an acute angle Ä with the extension 37 of the side facing the stack of leaves on the resting position lower end blade 13. This acute angle 5 is preferably located between lo and 100, in particular between 20 and 40.

The stirrup 5, which is recessed or recessed in the bottom 8 of the housing, can serve as a tilting element for setting up the housing 2 on a table, and for this it can be swung completely out of the house bottom 8, namely at least so much that it forms a pointed one and / or right angle with the bottom of the house. In these two situations can the jumper can also be lockable by snap action. Hereby can the housing 2 is to some extent used as an adjustable picture frame, whereby it can more precisely be set both on a short side and on a long side. Depending on the desire, it can then with certain time intervals on days, weeks or months a new image from the bar l is arranged below the substantially transparent housing top as the top blade in bar 1. 10 15 20 25 30 35 40 '? 809? 28-4 25 It should also be emphasized that the drive roller 4 should not be arranged too close to the socket slot, otherwise it would counteract the deflection of the edge l2 in the separating space 19. It shall however, also not be arranged too far away from the the slot, because otherwise instead of pressing the front the edge 35 of the blade 33 lying on the lower end blade 13 upward would load the blade 33 with such a pressure that the blade front edge 35 would rather be pushed down. Thus solved with the pressing roller 4 simultaneously has three problems, since this can adapt early to the degree of filling, as shown by it previous.

It should also be mentioned that the drive or transport roller 4 at the embodiment according to Figs. 1a and 1b can also be arranged at the opposite edge of the housing 2 in a corresponding recess and through finger pressure movable in the direction of the leaf stack l with its axis, so that it can be affected with one hand, at the same time as a blade taken out of the housing 2 with the other hand; thereby obtaining a natural working position for the user's hands.

Fig. 1c shows the housing bottom 8 in relation to Fig. 1a and 1b modified embodiment, wherein the drive roller 4 is arranged in a recess 7, which is wider than the length of the drive roller 4 and which starting from the center of the house extends towards the socket slot to near the edge of the house 8.

The drive roller 4 in Fig. 1c is mounted on a bracket 5, which is slidable along the bottom of the housing in the direction of displacement of the blades in the leaf stack l and which with its ends Sa is controlled in a pair in the housing recesses 7a formed at the bottom, which are covered towards the outside of the housing. bottom, so that the jumper ends Sa cannot exit the plane of the housing bottom 8. The stirrup 5 is held by a return spring 5b in that of Fig. 1c showed the sleep mode. The one attached to the other end of the yoke 5 the transport roller is designed as a freewheel roller, and more specifically it is locked against rotation when pressed by the user's hand towards the back of the adjacent blade and is pulled into it by an arrow 5c marked the direction, whereby it acts as a carrier and pushes the blade through the recess slot 10; it is made of one such material, for example rubber or plastic, that a relative large coefficient of friction is present between the underside of the blade and the transport roller 4. When the blade has come out of the the slot, the user can grasp and then completely pull out the blade he has released the transport roller 4, which is rotatable in the direction 10 l5 20 25 30 35 40 78097284; 26 opposite to the direction marked by the arrow 5c and by the return spring 5b is retracted to the rest position shown in Fig. 1c, whereby it can roll on the underside of the blade that is now at the bottom of stack. The advantage of the embodiment according to Fig. 1c compared to the embodiment according to Figs. 1a and 1b is that the direction of movement the movement of the user's finger corresponds to the direction of movement for the sheet to be removed.

From a manufacturing point of view, it is suitable that the stirrup 5 in the embodiment the ring shapes according to Figs. 1a - 1c are bent before the transport roller 4 arranged on the same. This is not normally possible but can be realized with a roller or roller shown in cross section in Fig. 1d, having a tangential from its axial opening 4a towards the rotational direction 4b, in an arcuate shape to the circumferential surface 4c continuous slot 4d, which in this case, then the material in the roll or the roller 4 is preferably elastic, has slightly less thickness or width than the wire or plastic shackle 5.

Fig. 1c shows a modification of the transport device according to Fig. 1c. In this case, instead of the jumper 5, there is a plate 5f, on which there is a stapling element 4e, for example of rubber, in the form of a small plate, which replaces the transport roller 4. The plate 5f is slidably mounted in the bottom 8 of the housing, more specifically so, that the staple element 4e attacks on the currently lowest the blade in the blade stack, thus the lower end blade 13 in Figs. 2a - 2c.

On the side which in Fig. 1c forms the underside of the plate 5f, it can is an edge or groove accessible to the user finger, so that the user only needs to move the plate in the pulling direction of the blade and then can release the plate when he has grabbed the blade. IN Fig. 1f shows a cover element 5g, which has a step 5h, on which the user can attack with one finger. The cover element is either mounted on the jumper 5 or arranged instead of the jumper 5, in the latter case the transport roller 4 being stored on the cover. the element and this itself is slidably arranged in the bottom of the housing. ten 8.

Fig. 3a shows a modified embodiment of the device according to Fig. 2, in which there is a slide 39, which is almost completely, with the exception of a short piece, extendable out of the housing 40, which is otherwise built in the same way as the house 2. The slide has on both sides a leaf spring 41, which presses the removed leaf upwards against abutment surfaces on the slide. The advantage of this embodiment 10 15 20 25 30 35 40 7809728-4 27 form consists in that when re-inserting the removed blade does not need to "aim", so that the re-insertion position of the blade is ensured and the reintroduction takes place semi-automatically.

Figs. 3b and 3c show a modification which makes the springs 41 redundant. Here is on the end of the slide, which is located at the back in the pull-out direction of the slide, thus at the places that are designated 39b in Fig. 3a, a cam-like elevation 39a on the bottom of the slide at each side of the slide, and the part on which the blade edge abutment surface ll is located and which is designated here with 39c and is triangular in cross section but can also have another cross-section, is rotatable about an axis 39d in that of an arrow 39e marked direction, namely against the action of the elastic force from a spring, for example a torsion spring.

When the cam-shaped elevations 39a at reintroduction abuts the lower edge of the rotatable wedge part 39c in Fig. 3b, then they turn the wedge part in the direction marked by the arrow 39e, wherein the blade 39f to be inserted is deflected upwardly along it facing the blade facing the surface of the wedge part (see fig. 30), so that the blade upon continued insertion of the slide 39 into the housing is inserted into it not shown the insertion slot 16.

Figs. 4a - 4f show a further embodiment, with which a fully automatic removal of the leaves from the leaf stack and a fully automatic re-insertion of the leaves into the leaf stack is possible; out- the removal and insertion takes place by pulling out a slide 43 from the housing 42 and then again pushes the slide into the housing.

The slide 43 is movable so far at right angles to it in this case the top slot 10 arranged at the top, that it is completely takes it for each occasion out of the socket slot 10 coming the blade 44 on the transport surfaces 45 provided for the purpose, on which the blade is re-inserted into the insertion slot 16. However, the slide is included appropriate appropriations secured against complete withdrawal from the house.

The slide 43 is guided in the housing for its reciprocating movement, and for this it has a frame 46 (see Figs. 4d and 4f) with slide parts 47 extending in the direction of movement of the slide, which are sliding slidable in corresponding recesses 48 on the inside of the housing 42 and / or at the bottom of the house. The slide can be controlled in the house on many different ways and also designed in widely different ways; it can, for example, be telescopically extendable.

Preferably, the slide 43 is partially guided against the side walls on the housing 42, so that the surfaces of the slide face the interior of the slide l0 15 20 25 30 35 40 7809728-4 28 control parts have contact surfaces, with which it is removed from the housing the pulled blade is secured sideways so that it is prevented from falling out of the slide.

In the embodiment shown in Figs. 4a - 4g, the slide comprises 43 also a substantially transparent housing section or housing lid 49, which may consist of a clear sight plate 50 attached to a frame 51 (see Fig. 4f). To prevent the leaves from falling out of the slide when this is elongated and the leaves are practically free on the slide, the slide can be pulled out of the housing 42 only so much that the trailing edge of the rear edge of the frame 51 still covers the adjacent edge of the leaf stack l. At the other! end of the housing are tongue-shaped parts 52, which are also called holding tongues, as they grip over the edge of the top blade and hold it down with an image abutment surface, so that they prevent the blade from springing or falling out of the housing 42 when the slide 43 is extended.

At the operating side, the slide 43 at the bottom is extended in the direction against the housing 42 with a tongue 53. When the slide is inserted, it tongue 53 into a suitable distance, for example 10-14 mm, in the housing bottom, which at this place has a corresponding recess 54. The tongue 53 serves as a gripping surface.

The principle of the removal of a leaf and the reintroduction of the sheet complies with the principle already explained in connection with Figs. 2a - 2c, the blade edge abutment surface ll is arranged on a building part 55 fixedly connected to the housing 42, which also is called a separating wedge or separator and which limits one side of the removal slot l0 and one side of the insertion slot 16. The other the side of the removal slot l0 is formed by the inside of the slide top 49, and the other side of the insertion slot 16 is formed completely or partly of the slide members 47 extending in the movement of the slide direction. The separator stop is formed on each side of the slide arranged springs 56 (of which only one is visible in fig. 4a), more specifically by a front extension in the pull-out direction of the slide bending 57 on the springs. These springs, also called retaining springs, springs, also has the task of transmitting it out of the the blade 44 coming to the blade 44 to those arranged on the slide the transport surfaces 45, on which the blade is inserted into the insertion slot 16, whose insertion stop 58 is formed by one or more resilient tongues on a pressing plate, which is under pressure from a spring 60 and thereby pushes the blade stack 1 against the inside of the slide transfer 10 15 20 25 30 35 40 7809728-4 29 paragraph 49.

The projection of a blade through the removal slot 10 takes place by partly a gripper 61, which is arranged on the rear end of the slide the upper part 49 and is substantially in the form of a heel or nose, to which, in the pull-out direction of the slide, a gripper cavity 62, which has the task of enabling it in engagement with the gripper coming edge of the blade to be removed to securely hook in under the influence of the pressing plate 59.

The gripper cavity 62 may, for example, be a recess with a width of ca. 3 mm and a depth of 0.5 mm. In this way, the gripper edge will to some extent extended to the "harmless" side, ie upwards, there the second top image could not be touched.

This is especially advantageous if it engages the gripper the coming edge of the blade is damaged by sprain, ie. breddad.

This prevents the blade from being further damaged.

The safe operation of this system is based on it generally present fact that they as leaves are preferably used the inverted images have an acute cut angle at the edge edge that is on the image side and has a blunt cut angle at the opposite set the edge.

A wedge part 63 is rotatable about a shaft 64, so that on the the same existing holding tongues 52 completely release the leaf the stack 1 in the area of the left edge in Fig. 4a when the wedge part turned away from its resting position. In this way the leaf stack 1 can be taken out of the housing 42 when the slide 43 is extended. In particular, it is made possible thereby a simple and automatically feasible filling of the house 42 with a stack of leaves l.

In order to keep the rotary wedge securely in its normal position, as is the position shown in Fig. 4a, there is a locking device. This formed essentially by a plant arranged on the inside of the bottom of the house; surface 66 and by one on the opposite side of the rotatable wedge part 63 arranged counter-plane surface 67, the plane surface 66 and the counter-plane surface 67 abut elastically against each other, which can be achieved by the elasticity of the appropriately designed housing base. Against- the flat surface 67 transitions in the direction of the outside of the housing in an arcuate shape surface 68, whose radius of curvature r increases to a radius r- + Ar, whereby r denotes the distance between the axis of rotation 64 and the plane surface 66.

On the other side of the rotatable wedge part connects to the the flat surface 67 a nose 65, which grips under the adjacent edge on the leaf stack 1 and when the wedge part 63 is extended from its normal 10 15 20 25 30 35 40 780-9728-'Å 30 position lifts the stack of leaves at the edge so that the stack of leaves kelp can be taken out.

At the upper end, the rotatable wedge part 63 has two steps shaped ledges 99 and 100, the height of which is approximately equal to leaf thickness. These stepped ledges provide a sorting in such a way that the gripper 61 can practically grip only the edge of the top blade, for the following reasons: When the slide 43 is pushed back after the removal of a blade, bake to insert the removed blade at the bottom of the stack through insertion slot 10, exerts the housing transfer applied to the slide 43 paragraph 49 with its inside a frictional force on the top blade in the stack, which frictional force is partly transmitted to the sub- horizontal leaves. This frictional force causes the top blah that, as in the removal of the preceding blade by friction has been carried by the latter in the direction of the blade edge abutment surface ll, now pushed back again. Since the pressing plate 59 is pushed upwards, it can be pushed back only to it the first landing 100, which of course prevents the blade from moving further in the direction of the counter-blade edge abutment surface 30. the second top blade will be pushed back further up to the second landing 99, because that about it generally comes into contact with the lower one in Figs. 4a and 4c the edge of the first ledge 100 may slide past this edge, which is beveled or rounded. ' This pre-sorting also works at the corresponding dimensions. tolerances to which the leaves are exposed and due to which it may happen that the top leaf is shorter or longer than or as far as the second top leaf. This is explained further below. (a) If the top leaf is shorter than the second top blade, it may well be that the first stairway the batch 100 comes into contact with the edge of the second top leaf. that before the top leaf has arrived at this ledge.

Then, however, by the frictional force between the sheath head 49 and the top blade transmitted motion is significantly greater than the movement between the top and the second top leaf, comes the latter finally being displaced by the top leaf and pushed further back past the rounded edge of the first the ledge 100 back to the second ledge 99. (b) If the top and second top leaves are the same length, 10 15 20 25 30 35 40 7809728-4 31 during the extraction of the slide during the removal of the going blade the rear edge of the top blade in Fig. 4a at the beginning of the repeated insertion of the slide to lie down further to the right than the corresponding edge on the next top the blade, so that the edge of the second top blade first enters contact with the first landing 100 and then displaced of the edge of the top blade to finally be pushed back up to the second landing 99. (c) If finally the top leaf is longer than the next top leaf, its leaf edge first comes into engagement with the first the landing 100, while the corresponding edge on the next top the blade will be further to the right. Even in this case is the blade edge of the top blade which the gripper is to grip, securely separated from the edge of the next top leaf.

A reliable function of the gripper edge 61 and the the separation serving the ledges 99 and 100 are ensured by the holding tongues 52, on which the two stepped the kits are arranged, are doubly secured at the exact correct height it, namely partly through the above-mentioned locking device, by which the rotatable wedge part is securely kept in its normal position, partly through recesses 84 arranged in the sheath top piece 49.

The conical coil spring 60 is so designed or arranged, that it exerts a stronger pressure on the left part in Fig. 4a of the pressing plate 59 than on the right part. Thereby is achieved partly that the blade edge is securely pressed into the gripper cavity 62 at the rear end of the slide, and that an obstruction of the supporting the forward bends 57 on the retaining spring and 56 are avoided.

It should be noted that the pressing plate 59 and the the resilient insertion stop 58 may consist of a single part of the resilient the metal or plastic, which in addition may have punched in its interior tongues, which can exert the action of the springs 60. The resilient the guide stop 58 should be as wide as possible, so that not even over its entire length curved leaves can get stuck during reintroduction. Its- except that its elasticity is such that even if none or only few leaves are in the house 42 extending to the bottom of the house or in the nearest to this, so that a leaf to be inserted at low filling level of the housing is not pushed under the pressing plate.

As shown in Fig. 4g, the pressing plate 59 can also be constituted by one made of spring steel or resilient plastic round material 10 15 20 25 30 35 40 78097284: 32 "wire rack". Such a part may be bent by a single wire paragraph, and more precisely, this is so bent, that in each corner of an imaginary quadrilateral there is a coil spring 60a, which inserts the coil spring 60 and may also be conical.

The coil springs 60a are connected to each other by bridges 59a, which are extensions of the coil springs, and these bridges are in height with those over the ends of the coil springs 60a, varying through them to a certain extent they form abutment surfaces for the leaf stack l which in Fig. 4a is represented by the pressing plate 59. The two in Fig. 4g the front coil springs 60a are connected to each other mediating an intermediate bridge 58a, which likewise constitutes a elongation of the coil springs and extending obliquely downwards from the upper end of the coil springs, so that it fills the insertion stop 58 function and at the same time by its inclination deflects or leads the blade currently entering the insertion slot 16 upwards, more precisely in the same way as the front of the insertion allowance 58 end, which is not designated in Fig. 4a but which also extends down to the bottom of the house and rises obliquely upwards towards the interior of the house.

Fig. 4d shows a section through the gripper side of it on the slide 43 attached the upper piece 49. In this case there is in the gripper cavity 62 a strip 62a of a relatively high material coefficient of friction, for example rubber, whose preferably flat free surface 62 is offset with respect to the interior of the recess 62 to the lower edge 49b of the gripper, namely with the height h, which before ~ gradually amounts to 0.1 mm.

Instead of the strip 62a, a magnetic rod can also be used or magnetic strip about each blade in the blade stack 1 at its gripper sided edge has one or more flat elements, for example strips, of iron or other magnetically attractive material; these elements can be found, for example, on the underside of the leaves. Hereby is the magnetic force so large that it is essentially only sufficient to bring the top blade. Although the next leaf in some extent is taken by the magnetic force, which, however, is significant weaker at this blade, the blade is retained by the separating wedge 55.

Finally, Fig. 4e shows a section through the upper piece 49 in an embodiment where the springs 56 are replaced by a resilient and transparent plate 56a, which in an unloaded state has a bend 56b corresponding to the insertion appropriation 58. Manufacturing technology is this of great advantage, since the upper 49 and the resilient l0 15 20 25 30 35 40 78097284; 33 the plate 56a can be sprayed double of transparent plastic, closer determined preferably by the same material in a work operation.

The plate 56 has at 56b (like the spring 56 in the area 57) a relatively low, bent portion 56c, so that the blade is exposed pressure over a fairly large length range. In addition, the plate relatively strongly curved at both 56d and 56e.

Figs. 5a and 5b show a device in which the partition and the extension of the blade to be removed is provided by a suction device 90, which is connected to a suction pump 91. This suction pump is operated and controlled by a slide.

Fig. 6 shows in longitudinal section a particularly advantageous embodiment. in the form of a device where the top blade for each occasion in a leaf stack is carried by means of a suction device. Like devices In Fig. 4a, this device comprises a housing 42 with a slide 43. The slide consists of two parts, namely a first part 43a, which constitutes the main part of the slide, and a second part 43b, which is located at the front end of the first in the pull-out direction of the slide section 43a. The second part 43b is displaceable a distance E in the pull-out and insertion direction of the slide 43, which is marked with a double arrow 70. When pulling out and inserting the slide 43 the user grips the slide at gripping surfaces on the slide part 43b. Found the parts in the position shown in Fig. 6, the slide part 43b comes to a later insertion of the slide 43 into the housing 42 first to with its abutment surface 71 to arrive at one on the first slide part 43a arranged abutment surface 72, before the slide parts 43a and 43b together pushed into the house. When the slide is pulled out, this is the situation reverse, i.e. first the slide part 43b is moved, while the slide part 43a is retained in the housing due to the frictional resistance worked off from the house. The slide member 43b is moved until the the stroke 7la is at the distance E from the stop 72, and thereafter the slide part 43b can not move further away from the slide part 43a, but it brings with it the latter.

The reason why the relative movements of the slide parts 43a and 43b are limited to the section E is as follows: The slide part 43b is attached to a rod 73 during mediation a piston 74, which is movable in a cylinder 75, which is arranged at the rear end of the slide part 43a in the pull-out direction of the slide 43 and whose axis is parallel to the extension and insertion of the slide direction. If now the slide 43 is completely inserted into the housing, the piston 74 is in its leftmost position, in 10 15 20 25 30 35 40 7809728-4 34 which its leading edge 76 is in the position marked by a dashed line 77. If now the user pulls on the slide part 43b, the piston 74 is initially pushed to the right from this position to until its movement is stopped by the end of the cylinder 75, so that the slide part 43a is then forcibly included.

At this displacement of the piston 74 a negative pressure arises in the cylinder 75, and by this negative pressure the top it against a suction opening 78 opening into the cylinder 75, around whose edge a seal 79 is provided. This seal 79, such as may be an O-ring of rubber, is so arranged that its against the blade the side of the bar 1 is flush with the underside of the slide upper piece 49, this in order to as small frictional forces as possible shall be applied to the top blade when re-inserting the the 43 in the housing 42. Possibly a wide, shallow depression 80 be arranged around the suction opening 78 and the seal 79, wherein the seal 79 may even be slightly recessed in the sheath cover 49, since the upper side of the blade 15 may then bend slightly in the depth 80.

As already indicated above, the frictional resistances are so that the relative motion of the slide members 43a and 43b meets one less frictional resistance than the pull-out and push-in movements of the slide 43, a condition which is a precondition for a real one functioning. Otherwise, the device of Fig. 6 can to a large extent be constructed in the same manner as the device in Fig. 4b, and a reference is therefore made to the description of the latter the device in terms of additional details, such as plate 59 and the spring 60, which later in this case of the two resilient ends of the pressing plate.

With reference to Figs. 7a - 7e, a device now appears removal of the entire leaf stack to be described in more detail; in these figures show only the slide which can also be called a drawer and hereinafter referred to as above and in the claims use the designation is the "additional" slide, ie. the slide which is affected only for removal of a stack of leaves from it only partially showed the house. For the rearrangement of the house, the leaves, a slide may be provided at the left (not shown) the side of the housing, which side can be designed for example as it the right side in Figs. 4a and 4b with the slide 43 for rearranging the blades; Figs. 7a - 7e are thus thrown sideways in relation to the mentioned figures. Is there such an additional slide in the device 10 15 20 25 30 35 40 7809728-4 35 according to Figs. 4a and 4b, the wedge part 63 need not, of course, be rotatable.

In the image shown in Fig. 7a of a section along the line I-I i Fig. 7b shows a part of a housing l0l, and more specifically can be seen in Fig. 7a shows a part of one of the two side walls 102 and 103 of the housing 11, while this figure of the bottom of the house l04 shows only a few special parts, which will be discussed in more detail later.

In the housing 101 a stack of leaves (not shown) can be accommodated, which is laid on the bottom 104 of the housing 104, so that the blade surfaces will lie parallel to the bottom and the stack of leaves on the sides is surrounded by the walls 102 and 103 and the additional side wall 105 and a no visible, the latter side wall opposite side wall. On the side wall 105 there are holding fingers 106, which grip over the leaf stack. At it the side wall 105 opposite side is on the housing 101 and / or on a for rearrangement of the leaves in the leaf stack serving slide arranged projections, which with a predetermined length grip over the stack of leaves when the latter slide for rearranging the blades is maximally pulled out of the house. The stack of leaves can therefore not be readily removed from above taken out of the house, and it is not even possible to from above insert a leaf pile into the empty house.

In order for this possibility to exist, the 101 side of the house is wall 105 mounted on a slide 107, which is held on the housing l0l by a locking device.

The locking device comprises a holder arranged on the slide 107. latch 108, which in the locked state of the slide 107 engages in one on the housing 10 or more specifically arranged on its bottom 104 locking stop 109, so that the slide 107 can not be moved in this position out of the housing 101 to the right, seen as in Figs. 7a - 7e.

The holder latch 108 is mounted on a tongue 110 and can penetrate swing of the tongue in the direction indicated by an arrow III, so- is directed inwards towards the interior of the housing 101, is disengaged from the locking the stop 109. In order for the engagement between the retaining latch 108 and the locking stop 109 should not be released unintentionally, the tongue ll0 so arranged or mounted on the slide 107, that it by its own elasticity holds the retaining latch 108 in engagement with the locking stop 109, unless a pressure in the direction indicated by the arrow lll exercised from below on the tongue.

When the tongue 110 is swung upwards in the direction marked by the arrow III, the upper side of the tongue engages with the one not shown the leaf stack, and for the tongue when pulling out the slide l07 to 10 15 20 25 30 35 40 780972841, 36 to the right should lead with the leaf stack is an engaging surface 112 with large friction arranged on the tongue, and more specifically is in the present embodiment for this purpose a friction element 113, for example show a rubber plate, applied to the top of the tongue.

In order for the tongue 110 to be easily found with the fingers and to prevent it from being inadvertently present on the tongue underside of a finger grip recess 114, see in particular Fig. 7c.

This finger grip depression 114 is located in the embodiment shown. the mold at a short distance from a gripping surface 115, which is grooved and serves to hold the housing 101 when you do not want to pull out the slide 107. For the user to quickly be able to move the fingers with which he holds the housing from the gripping surface 115 to the finger grip recess 114 the latter can also lie immediately next to the gripping surface 115.

In the embodiment shown, the slide 107 comprises a tongue-shaped guide member 116, which as shown in Figs. 7d and 7e extends to the gripping surface and there is attached to the rest of the slide 107 or is made in one piece with this. The tongue 110 thus lies in a longitudinal recess 117 in the guide part 116, and the latter is displaceable in the direction of movement of the slide 107 in the bottom 104 of the housing in that it is stored at its side edges in guide surfaces 118 in the bottom 104 of the housing. These guide surfaces 118 may form, for example a salmon tail guide, which may otherwise be so arranged and shaped, that the guide member 116 at its side edges 119 neither in direction towards the interior of the house or outwards can come out of engagement with the guide surfaces 118.

On the guide part 116 there is a stop 120, which can be shaped in the same way as the retaining latch 108 but which may also have another form. This stop cooperates with a counter stop 121 on or in the bottom of the housing 104. Thereby the movement of the slide 107 is limited out out of the housing 101, thus in the one marked by an arrow 122 (see Fig. 7a) direction, namely to a distance slightly longer than that above said predetermined length by which the stack of leaves is overlaid at the slide 107 opposite the side of the housing 101. If, therefore, an sufficient pressure is exerted on the tongue 110 in that marked by an arrow lll direction, the blade stack is taken off by the friction element 113 the slide 107 at its extraction, the leaf stack at the i Figs. 7a - 7e, the left side of the housing 101, not shown, is pulled forward below the projections or other overall parts arranged there on the housing and / or on another rearrangement of the leaves in the leaf stack 10 15 20 25 30 35 40 78097284: 37 c serving slide. When on the other hand the leaf stack in the area of the set sidewall 105 is still held by the retaining fingers 106 and thus here can not move upwards, despite the pressure on the tongue ll0, this pressure causes only the left side of Fig. 7d the leaf stack is lifted, which, however, is quite sufficient and for otherwise purely advantageous, as it thereby prevents that the leaf stack due to excessive pressure on the tongue 110 is uncontrollable clay is pushed out of the housing 101 and falls to the floor or on otherwise dissolves into individual leaves, which then have to be laid again Sämman.

Then the stack of leaves, which has hitherto been in house 101, has been removed, the tongue 110 is released again, and possibly one is inserted new leaf stack in the housing 101, after which the slide 107 is pushed back into the the housing until the retaining latch 108 due to its own elasticity comes into locking engagement with the locking stop 109.

As will be apparent from the following description of the embodiment shown in Figs. 8a - 8f, one can use one slide similar or corresponding to slide 107, optionally including the individual construction elements, such as, for example the stop 120, the counter stop 121, the recess 117, etc., even in that case when no slide is used for the blade change, as is the case for example in the embodiments according to Figs. 1a - 1c and 2a - 2c.

In these cases, where the house can not be opened to a large extent, to by means of a slide arranged for the blade change, it is of course necessary that it serve for removal of the entire stack of leaves the slide, which will henceforth be called a drawer, has a larger one extraction distance, which is at least so large that the leaf stack without inconvenience can be taken out when the drawer is pulled out as much as possible.

The device shown in Figs. 8a - 8f constitutes a modification of the device according to Fig. 1b, and below will therefore only those significant deviations to be explained.

In the housing 2 there is a pull-out drawer 201, which as shown in fig. 8b can, if necessary, be extended so far that the one contained therein, no shown the stack of leaves can be removed in its entirety. In order to press the roller 4 should in principle function in the same way as in the guide according to Fig. 1b is located on the underside of the drawer 201 a corresponding recess 202 ', which is so large that it surrounds the shaft 6 pivotable support 202, which corresponds to the yoke 5 in Fig. 1b or can be replaced by such a jumper, in order to adapt to different thick leaf stacks can move into the interior of the housing 2, 10 15 20 25 30 35 40 7809728-4 38 as marked by dashed lines in Fig. 8d. At the free at the ends of the sides of the support 202 there are projections 203, which due to the design of the front free end portions of the side 202 of the support parts can fold away elastically for the adjacent edges 204 on the bottom of the housing when these exert a pressure on the support 202. These projections serve to push the support 202 into the housing 2 at its free end prevent the support from returning by itself move out of the house. This allows the support 202 to be snapped into the housing, which is important, for example, for a pocket-friendly storage. Through this snap prevents the support 202 from protruding and gets stuck, for example on a chest pocket in which the housing 2 is to be plugged in.

On the front portion of the drawer 201 in the pull-out direction is located in the middle of the adjacent side recess 205, as seen from above are, for example, semicircular. The leaf lying in the drawer 201 the stack can be gripped through these recesses 205 directly between the thumb and index finger and is taken out of the drawer 201, which has a grip surfaces 206 on the sides for easy pulling out of the housing 2.

A stop 210 arranged in the bottom of the drawer 201, which acts with a corresponding counter-stop in the housing 2, blocks the extraction drawer 201 in its position inserted in the housing 2 and prevents full constant pulling out of the drawer.

On its front, the slide further has a groove on each side for inserting a label 207, which may be provided with a content holding task. Finally, the first stacking protrusion 208 is on the upper side of the housing 2 and second stacking projections 209 on the lower side of the house. These projections are so arranged that when several houses placed one on top of the other, the upper stacking projections are gripped 208 practically versatile of the lower stacking projections 209, so that you can pull the drawer out of one of the stacked houses without this house having to be taken out of the stack.

The device shown in Figs. 9a - 9d is a modification of the device according to Fig. 4a, and in these figures only those are shown significant deviations from Fig. 4a. _ Inside the slide 43, which for rearranging the leaves in the leaf stack 1 pulled out of the housing 42 in the direction indicated by the arrow 2ll and then pushed back into the housing, there is a drawer 212, which remains still in relation to the slide 43 during this movement. For this blade shift operation of the device, gripping surfaces 213 are located on the side. of the front end of the slide 43, and at the opposite end of 10 15 20 25 30 35 40 78997284 » 39 the housing 42 has upper and lower gripping surfaces 214.

If you want to remove the entire stack of leaves 1, pull the drawer 212 out of the housing 42 and the slide 43 in the direction indicated by an arrow 215 a separating wedge 216, which is mounted on the drawer 212, is pulled out, while the pressing plate 59 and the springs 60 remains in the housing 42 together with the slide 43. The drawer 212 the bottom has for this purpose a recess 217, so that the the box 212 seen from above is U-shaped, as best seen in Fig. 9b.

To pull out the drawer 212 from the slide 43, you grab it in the side gripping surfaces 218, which are arranged on the drawer at its in the pull-out direction front end, partly in the sliding 43 gripping surfaces 213.

Unlike what applies in the embodiment according to Fig. 4a is the part 219, by means of which the uppermost blade 15 is taken out of the leaf stack by projecting to the side, not mounted on the slide 43 but on the housing 42, so that the top blade 15 is held in the housing of the part 219, while the rest of the leaf stack 1 is carried out the housing with the slide 43. A The part 219 is pivotable a predetermined, small angle in an i the upper part of the housing designed recess 220, which has essentially the same shaped like the part 219. At its right end in Figs. 9a and 9c the part has 219 a cylinder surface 221 which abuts a corresponding cylinder surface 222 in the recess 220, whereby the part 219 can turn through relative displacement of the cylinder surfaces around the cylinder axis. The the opposite end 223 of the part 219 can thereby move upwards and downwards between two stops 224 and 225 in the recess 220. On the upper side of the part 219 there is a recess 226, in which there is a leaf spring 227, which abuts partly against the part 219 and partly against the recess 220 upper wall and thereby pushes the part 219 downwards, so that the end 223 is pressed against the stop 225 when it is not affected by an opposite direction force.

On its side facing the leaf stack 1, the part 219 has a stapling element 228, which consists, for example, of rubber and is mounted in a recess 229 in the part 219. The stapling element 228 projects slightly from the part 219, so that it surely engages the top blade 15 in the leaf stack 1. In the direction of movement of the leaf stack 1 (arrow 230) after the adhesive element 228 there is a hook-shaped projection 231, which pushes past the staple element in the direction of the leaf stack 1, namely gen a piece slightly smaller than the thickness of a leaf in leaf stack 1.

The mode of operation of the stationary part 219, which can also be 10 , l5_ 20 25 30 35 40 78097284: 40 drawn as a stationary carrier element, is as follows: When the slide 43 is inserted, it lies in the extension of the slide. direction of the front end 23l 'of the blade stack 1 always under the adhesive element 228, as shown in Figs. 9a and 9c. When the slide 43 pulled out of the housing in the direction indicated by the arrow 211, the staple member 228 holds the top blade 15 through its friction intervention with this blade. About the friction for some reason is not enough, the blade 15 can move relative to part 219 only until it engages the hook. shaped protrusion 231, which, however, cannot grip the next blade in the leaf stack. Through the described arrangement a safe is obtained holding the top blade 15, which is peeled off from the blade stack 1. The leaf spring 227 has the function that if the leaves are not completely flat always ensure a safe intervention between on the one hand the staple member 228 and the hook-shaped projection 231 and others side the top blade 15. When the slide 43 is pushed back into the housing 42, the hook-shaped projection 231 causes the uppermost the blade is not touched by the staple member 228, so that the blade stack 1 without major resistance can be passed under the part 219.

Another embodiment of a carrier member 233, which is similar to so has a hook-shaped projection 234 and one, for example, of rubber existing staple element 235, is shown in Figs. 10a - 10c. The staple element 235 and the hook-shaped projection 234 are arranged on the circumference to a roller 236 with one lying after the other in circumferential the direction. The roller 236 is rotatable about its axis 237, which is parallel to the blade stack 1. The rotation of the roller 236 about the axis line 237 is guided by a cam 238 fixed on roller 236 and a cam guide member 239, which in turn is stationary with respect to the roller 236. In the device according to Fig. 4a, for example, the roller the shaft 237 be mounted on the slide 43 instead of the gripper 61, at the ridge guide part 239 is arranged on the housing 42.

The mode of operation of the carrier element 233 is immediately apparent of the three positions shown in Figs. 10a - 10c. The carrier element 233 is controlled so that when subtracting the top from the leaf stack 1 in the direction marked by an arrow 240. one is initially only the staple member 235 engaged with this leaf. This position, shown in Fig. 10a, serves to provide a ledge formation between the top blade 15 and the underlying leaves in the leaf stack 1, in that the uppermost the blade 15 by the adhesive action between this blade and the adhesive 10 15 20 25 30 35 40 780972841 41 element 235 is displaced a bit to the side. After this firing, the cam 238 engages the cam guide member 239, which through the driver element 233 a predetermined angle is rotated in the counterclockwise direction, more precisely so that the hook-shaped projection 234 engages the trailing edge of the blade 15 and thereby after carrying this leaf. During the entire transport of the blade 15 the hook-shaped projection 234 is held by the straight, flat surface the cam guide member 239 in one and the same position, which is such that it in engagement with the trailing edge of the blade 15 lying the hook surface on the protrusion et 236 is perpendicular to the blade edge. As can be seen directly, the height h on the chin surface without further ado being greater than the thickness of a blade, since the hook-shaped projection 234 engages with the rear the edge of the blade 15 only when the blade has already shifted one piece in relation to the leaf stack 1, whereby the protrusion 234 has no possibility of gripping an additional leaf edge.

The hook-shaped projection 234 can thereby grip the top the blade very reliable.

At the return of the carrier element 233, as shown in Fig. 10c, the driver element is rotated by the cam 238 and the cam guide member 239 i the opposite direction, thus in the clockwise direction, about the axis 237, so that both the hook-shaped projection 234 and the staple element 235 are ineffective and the roller 236 with a smooth, for example off plastic formed sliding surface 241 can slide over the leaf stack in that of a arrow 242 marked the direction.

It should also be noted that a resilient contact pressure is constantly maintained between the stack 1 and the carrier element 233.

Furthermore, it should be emphasized that the carrier element is not necessarily must be in the form of a roll without, in principle, turn any suitably rotatable member having one facing the leaf stack 1 convex surface, on which the hook-shaped the jump 234, the adhesive element 235 and the sliding surface 241 are arranged in consequence in the circumferential direction.

Figs. 11a and 11b show one in relation to the device i Fig. 4a modified device. The device in Figs. 11a and 11b differs from the device in Fig. 4a mainly by feeding removing the leaf stack not shown, the top piece 49, which is applied to the slide 43, folds up as a lid, as marked with dotted lines in Fig. 11a. The lid 49 can be locked in closed position by means of a projection 243 arranged thereon, which can snap elastically into a recess 244 in the slide 43. For maneuvering l0 l5 20 25 30 35 40 7809728-4 42 The slide 43 is located at its front end gripping surfaces 245. to and below, and on the opposite side of the house is on sides corresponding to gripping surfaces 246.

The device shown in Figs. 12a and 12b constitutes a modification of the device in Fig. 1a, and more specifically the device in Figs. 12a and 12b so designed that it can be placed in a piece of transparent plastic. This means that the housing 2 with its top piece or lid 2a and with its part 2b, which has the blade edge abutment surface ll and which at one side limits the removal slot 10 and on the other hand limits the insertion the slit 16, are made in one piece, the direction of the arrow 2c being The fold-down lid is connected to the rest of the the housing 2 under the mediation of a plastic joint 2d. Removal slot l0 formed here by a recess formed in the bottom 2 of the housing, which in the middle the part of the house has an extension 2e towards the house, through which the lower blade can be gripped with a finger and slid in the direction of the take-out slot 10, so that it can then taken out of the house. This is indicated in Fig. 12a.

It should be emphasized here that individual characteristics of which any of the embodiments described above can be transferred to other of the described embodiments, if this is technical meaningful in terms of the freely selectable leaf exchange process or in other respects, for example in the design of it rotatable wedge part or device of the lid of the housing or piece on the slide or on the house. In this respect, they constitute in the dependent references to the dependent claims previous claims no limitation, but the dependent ones the claims may within the framework of the technically meaningful also accede to other preceding claims other than those specified.

In particular, it is possible, for example, to replace those for sanding of the transport problem (pulling out a blade) use the transport elements, such as for example the gripper edge or the like, against each other or against other elements acting by attacking on or hold or exert friction against the blade to be taken out. Thus, for example, as on the blade attacking elements can instead of a gripper edge or a suction carrier use one brushed with freewheel action, thus with brushes as in the extractor the direction is skewed and when pulling out the blade takes the bar towards the underside of the blade, while at the insertion of the blade 10 15 20 25 30 35 40 7809728-4 43 "Kraft1öst" slides on the underside of the blade. Instead of the brushes you can also use one made of metal or another sharp material existing row of serrated protrusions, the serrated edges of which vessels obliquely in the pull-out direction of the slide, so that they penetrate to some extent into the underside of the blade, while at the re-insertion of the slide in the housing slides along the underside of the blade.

In Figs. 13 and 14, an image shown in its entirety by 301 is shown. carrier in transverse format, which is set up on a substrate. This image carrier consists essentially of a frame 302, one with this bound and preferably in one piece with the same backing wall 303 and a support 304, which when it serves for erection of the image carrier can also be called an adjusting part.

The support 304 is pivotally mounted in the rear wall 303, more specifically so that in the case of a non-erected image carrier it can be swung into the rear wall, its back 305 being flush with the back 306 on the rear wall and / or its front face 307 is flush with the front 308 of the rear wall 303. On the support 304 is a transport roller or transport roller 342 stored, which is explained in more detail below.

The image carrier 301 further has two holes 309 and 310, of which the hole 309 lies along one long edge of the image carrier approximately in the middle between its short sides, while the other hole 310 lies next to one of the short sides of the car carrier approximately midway between the long sides of the nose. These two holes 309 and 310, which are formed in the rear wall 303 of the image carrier, serves to suspend the image carrier on a suitable projection in the wall, for example a nail head, a screw head or similar.

The image carrier 301 can thus be set up and suspended as well standing as lying. The image, not shown in Figs. 13 and 14, is held in a column 313. adapted to the image thickness gap 313 lies between the front side 308 of the rear wall 303 and the non denoted the back of the frame 302 within the area between the dashed line 311 and the inner edge 312 drawn in Fig. 13 on the frame 302. In the area of one edge, namely one width page 317 on the image carrier 301, the column 313 continues in full width all the way out, so that the image from this side of the image carrier 301 can be inserted in the latter and in the inserted position is supported by the front side 308 of the member 303 and that of the inner edge 312 of the frame 302 closed surface. - The thickness of column 313 depends on the thickness of the image 10 15 20 25 30 35 40 78097284 » 44 and, where appropriate, in particular when it comes to a lot large format, the thickness of a transparent cover plate and / or rear support plate or support foil. For the usual purposes can the gap thickness is between 0.1 and 1 mm, preferably between 0.25 and 0.75 mm, the range 0.4 - 0.6 mm being particularly that prefer.

At the point where the column 313 opens into the outer surface of the image carrier the gap can be funnel-shaped extended in cross-section throughout the column length, this to facilitate the insertion of the image.

However, it is especially preferable to design in this place the gap 313 so that the side edge 314 of the rear wall 303, as in Fig. 13, is marked with a dotted line, along the mouth of the column 313 is offset inwardly relative to the side edge 315 of the frame 302, so that one wall 316 (not directly visible in Fig. 13 and 14, however, compare Figs. 17 and 21) on the open gap 313 at the outside of the image carrier is shortened relative to it the second wall 318. The part of the wall 318 which projects past the wall 316 thereby forms a side stop for an image to be inserted in the column 313, thereby facilitating insertion. A funnel- In addition, similar to that shown in Fig. 21, except is formed by a cross-section extending across the entire width of the gap 313. bevel 321 on wall 316.

The rear wall 303 further has a preferably rectangular shape. 329, in which the support 304, shown in more detail in Figs. 15-17, can be retractable. For this purpose, the aid may 302 be pivotally mounted in the rear wall 303, namely so that it can pivoted backwards from the rear wall 303 around one of its side edges, preferably around the side opposite its longitudinal direction. edge 330. In the embodiment according to Figs. 15-17, the side edge passes 330 for this purpose at their ends in preferably spherical pins 331 projecting over the longitudinal side edges 332 on the support 304 and intervenes in the corresponding recesses, which are made in the 329 side edges of the recess and in which the pins can be inserted elastic.

In order for the support 304 to remain or be able to be locked in different angular positions, can, although in some cases the squeezing of the support in the rear wall in the area of the pins 331 may be sufficient, a friction and / or barrier surface 334 may be arranged around one of them or, as shown in Fig. 15, both pins 331. In this case this surface is made in the form of a toothed surface, which is shown in larger 10 15 20 25 30 35 40 78097284! 45 scale in Fig. 17. The teeth 335 on the surface lie radially against the pivot axis axis 336 of the support 304 and projects slightly beyond the the edges 334 of the support, as shown in Fig. 15. Although in principle, it is possible that on the surface of the rear wall, against which surface 334 abuts, form corresponding teeth 335, need this not necessarily done in the illustrated embodiment, because the barrier surface 334 touching the edges of the rear wall already in association with the clamping effect exerted by the back wall to some extent seems like counter tooth.

Although the support 304 may otherwise be flat, in particular rectangular and part adapted to the recess 329, which is designed with a recess 337 for easy gripping and swinging out of the back wall 303, it can instead be designed for material-saving purposes with two longitudinal side pieces 338 extending radially from hub 336 and preferably tapers at those spaced from hub end lying ends 339 (see Figs. 13, 14, 16 and 18) and are connected to each other by means of one or more transverse pieces 340, which in this case are disc or platform. Thick- the play on the crosspiece 340 is less than the thickness of the side pieces 338, and even in this case there is a recess 337, which partly serves to facilitate the gripping and swinging of the support out the rear wall 333 and to receive a transport roller or waltz 342.

For storage of the transport roller or transport roller 342 is available in the area of it facing away from the pivot axis 336 the end of the support 304 has a hole 341 in each of the side pieces 338.

These holes serve as bearings for the transport roller or roller 342 shaft 320.

The recess 329 in the rear wall 303 extends towards the edge of the the carrier and slightly past the inner edge 312 of the frame 302 (see Fig. 14).

As a result, the back of the frame 302 forms a stop for transport. the roller or transport roller 342. This stop is at empty carrier 301 is a direct stop, while in the case of an inserted image it is one indirect impact, since in such a case the image edge portion is located between the appropriation and the ends of the aid 339. Thanks to this appropriation can the image inserted in the image carrier is not damaged during the swing-in of the support 304 in the rear wall even if a transparent cover plate for car its front is missing, as the support is prevented from pressing the image outwards or even penetrate the image, and above all this appropriation forms a support for the front of the image in that area, 10 15 20 25 30 35 40 780972844 46 where the image comes into contact with the transport roller or rollers 342.

In the embodiment of an image shown in Figs. 18 and 19, carrier there is also a freely rotatably mounted transport roller or transport roller 342, which is arranged in the vicinity of it up to the outer side of the image carrier's side edge 317 walking column 313 opposite a support surface for the front or part of the front of the image.

The support surface is formed in this case by the back facing the image a transparent cover plate 343.

The roller 342 is arranged in the area of it from the support. its pivot axis 336 facing the end of the support, namely things in the rear wall socket 337 (see fig. l3-15) or in a separate recess 344, shown in Fig. 18. The roller 342 consists of preferably corrugated, grooved or otherwise roughened materials, in particular of rubber, so that the circumferential surface of the roller or the roller gets a frictionally good grip on the back of it in Figs. 18, 19 and 21 show in more detail the image which lies between it transparent cover plate 343 and back wall 303.

With the roller or roller 342, the picture can be very simple and without risk of wrinkles forming being transported in in the image carrier by attacking the externally accessible the circuit surface of the roller or roller to rotate it. On the contrary correspondingly, the image can be easily removed from the image carrier. Then the roll or roller by its bearing on the free end thereof the pivotable support 304 can be moved towards the image and thereby at its handling is always pressed against the back of the image, ensuring one good engagement between the circumference of the roll or roller and the back in the picture.

The transparent cover plate 343, which covers the front of the image, is applied so that its side edges 345 lie in and is held by the gap 313 between the rear wall 303 and the frame 302. In the the carrier according to Figs. 18 and 19 as well as at the later Thus, the written image carrier in Fig. 211 does not serve the column 313 not only to capture the image, but it also occupies the shiny cover plate 343. In order for the cover plate to remain in the image carrier when changing the image is the thickness of the outwardly going gap 313 smaller than the thickness of the cover plate. The implementation The shiny cover plate 343 can be easily replaced by detach the frame 302 and the rear wall 303 from each other, if these parts are connected to each other, for example by a plug-in connection, 10 15 20 25 30 35 40 '7809728-'4 47 formed by cylindrical projections and against these corresponding holes.

The cover plate 343 preferably consists of mineral glass, but it can also consist of transparent plastic, and it can further be toned, in particular have blue tones, pink tones, gold tones, silver tones or smoke tone. Furthermore, the cover plate can consist of a glare-free or mirror-free material or of material that has been made glare-free or mirror-free.

In the area of the recess 329 formed in the rear wall 303 for recessing the support 304, is a non-transparent cover plate 346 arranged. This cover plate is displaceable between at least one first and at least a second mode, of which the first mode is displayed in Fig. 18. In this position, the cover plate 346 holds a portion of the backing side of the image, so that it can be attacked directly or on it in Fig. 18 is engaged by the roller 342, i.e. the cover plate 346 leaves a portion of the recess 329 free in the area of the recess 337 or the recess 344, so that it is included in the image carrier. set the image with the roller or roller 342 or with the hand can gripped by the recess 329 and displaced laterally out of the image carrier. or, if the image is to be inserted, inserted completely into the image the carrier. In the second position, which is not shown, the cover plate is 346 offset so far to the right in Fig. 18, that its right end lies below the frame 302, so that it thereby completely covers the part of the back of the image which is held free by the recess 329 and not is located below the back of the frame.

This prevents an image inserted in the image carrier from getting "light spots", which could otherwise occur, especially at from the rear wall 303, support 304 is extended, if the image carrier is illuminated from behind stronger than from the front, which may be the case, for example, if the carrier is set up on a desk whose back is facing a window.

A recess 347 in the front of the rear facing image the wall 303 serves to slidably guide and accommodate it opaque cover plate 346. The depth of this depression is preferably equal to the thickness of the opaque cover plate 346. As partially shown in Fig. 19, the recess 347 extends preferably at all sides past the edges of the recess 329, so that the cover plate, the width of which is equal to the width of the recess 347 in Fig. 19 and whose length is equal to or preferably slightly greater than the length L of the recess 329, in the second position securely prevents all light access to the back of the image. 10 15 20 25 30 35 40 7809728-4 48 The opaque cover plate 346 may also be designed as transport slide 322 (see Fig. 20), whereby of course the roller or the roller 342 is omitted because the transport slide 322 has the same feature. The transport slide essentially consists of a plate 323, a tongue or another displaceable in the insertion direction of the image stored part, on which there is a control for its storage 324, which engage in corresponding guides (not shown) in the rear wall 303 or in the support 304 or, if the entire rear wall is designed as a transport slide, in the frame 302. On its back of the image side facing side, the transport slide 322 has a staple element 325, for example, a rubber plate, which carries the image. In Fig. 20 is the thickness for illustrative purposes greatly exaggerated; the staple element 325 can of course be very thin and for example consist of a thin rubber or plastic layer applied.

In order that the adhesive element 325 does not provide the entrainment effect in the undesired direction, the transport slide is so shaped or slidably stored, that a certain minimum is needed pressure to bring the staple member 325 into firm engagement with the the back, so that the user by alternately exercising a something harder and a rather weak pressure on the transport slide 322 can transport the image in the desired direction.

In the embodiment according to Fig. 21, it is located on the image carrier 301 rear wall 303 a container 326, which may be integral with the rear wall 303 and in whose interior 327 additional images can be stored.

The recess 329 is also here arranged in the rear wall 303, while the support 304 with the transport roller or transport roller 342 is arranged in a recess 329 in a cover 333 which is pivotable about a shaft 328.

This lid 333, which now forms the actual rear wall of the the carrier 301, is normally kept closed by a snap connection 348. When roller 342 is to be affected, the additional images are removed from the the holder 326, and after the lid 333 has been closed, the support 304 pivots against the rear wall 303 until the roller 342 engages the image. Hereby the user can change one in the column 313 at certain time intervals. set image against another image taken from the container 326.

The image carrier according to the invention has, depending on the embodiment form all or at least some of the following benefits: (a) The image carrier has a simple construction and an appealing appearance, in which case the preferred embodiment makes the slot the presentation of an image in the image carrier is trouble-free and particularly simple. (b) The image carrier is reliable and reliable, and in particular 10 15 20 25 7809728-4 49 the image is arranged self-holding in the image carrier, and it can by means the transport roller or the transport roller or the transport slide easily pushed in and out. (c) The image carrier can be handled easily and simply; car- it only needs to be inserted laterally through a slot, and it can easily replaced by anyone. (d) The image carrier is versatile, because it enables to show the image both landscape and portrait, and this both in suspended or suspended position. For erection has the image carrier a self-locking support, which is fully retractable in the rear wall, by hanging on a wall is facilitated. For hanging on a wall there are holes in which a nail head can be inserted both at hanging in landscape position and when hanging in portrait position.

Versatile usability also exists through the image carrier well suited for production for all image sizes. (e) The image carrier can be produced in terms of price, and in particular it does not necessarily have to have a coverslip, and it can be produced cheaply as a single part or, when the aid is produced separately, as two parts, and furthermore it requires a lot small material. The time required is also small, and in the case of The support springs the support with its pins easily into the corresponding taken in the back wall. The frame can cover all or part of its surface be imprinted, so that an ornamental or ornamental effect can be achieved. U (f) Finally, the image carrier can be easily transported, and in its embodiment for normal photographs it can be sent as a letter or in a letter, whereby the risk of a breach of the the cover glass disappears and the complete retractability of the support in the back wall promotes mailing.
