Abstract

La cassette destinée à être utilisée dans un dispositif possédant un écran pour l'affichage d'une pluralité d'images différentes de manière séquentielle comprend deux ensembles de feuilles, chacun divisé en bandes (1a, 1b, 1c) respectivement (2a, 2b, 2c). Les bandes se composent de lignes de coupe qui, à leurs extrémités, rejoignent des ouvertures. Les ouvertures dans les feuilles de l'ensemble le plus avancé s'étendent vers le haut à partir de la ligne de coupe, et les ouvertures dans les feuilles de l'ensemble le plus en arrière s'étendent vers le bas à partir de la ligne de coupe. Les feuilles et donc les bandes peuvent être ainsi déplacées mutuellement dans une direction verticale, et les segments d'images sur les bandes (2b) dans une feuille appartenant à l'ensemble le plus en arrière peuvent être déplacés vers le haut au-delà des bords supérieurs des bandes (1a) dans une feuille antérieure vierge (1). Les éléments d'images correspondant sur les bandes dans une feuille appartenant à l'ensemble le plus avancé peuvent être déplacés ultérieurement vers le haut pour couvrir les segments restants des bandes dans la feuille intérieure (1a), ce qui permet de composer et de rendre visible une image complète. Les mouvements verticaux des feuilles peuvent être commandés par des organes de guidage motorisés agissant sur les parties marginales des feuilles. Pour chaque image à montrer, la cassette doit contenir seulement deux feuilles portant des images identiques, c'est-à-dire une feuille d'image dans l'ensemble le plus avancé et une feuille d'image dans l'ensemble le plus en arrière.The cassette for use in a device having a screen for displaying a plurality of different images sequentially comprises two sets of sheets, each divided into strips (1a, 1b, 1c) respectively (2a, 2b, 2c). The strips consist of cutting lines which, at their ends, join openings. The openings in the leaves of the most advanced assembly extend upward from the cutting line, and the openings in the leaves of the most rearward assembly extend downward from the cutting line. The sheets and therefore the strips can thus be moved mutually in a vertical direction, and the image segments on the strips (2b) in a sheet belonging to the rearmost set can be moved upwards beyond the upper edges of the strips (1a) in a blank anterior sheet (1). The corresponding picture elements on the strips in a sheet belonging to the most advanced set can be later moved upwards to cover the remaining segments of the strips in the inner sheet (1a), which makes it possible to compose and render visible a complete image. The vertical movements of the sheets can be controlled by motorized guide members acting on the marginal parts of the sheets. For each image to be shown, the cassette must contain only two sheets carrying identical images, that is to say one image sheet in the most advanced set and one image sheet in the most advanced set. back.

Description

A Cassette and an Appurtenant Apparatus having a
Screen for Cyclical Displaying of a Plurality of Pictures.
The invention relates to a cassette for an apparat- us having a screen for cyclical showing of a plurality of pictures, each being composed of picture segments on at least two groups of horizontal strips, the strips in each individual group being made in one continuous sheet and be¬ ing separated from one another by horizontal cutting lines extending between two marginal portions of the sheet, and the various sheets being placed upon each other in such man¬ ner that the strips carrying the picture segments are gathered in a number of piles equal to the number of strips in each sheet, and the number of strips in each pile being equal to the number of picture forming groups, and each single sheet - with the group of strips formed therein - being displaceable in the plane, relative to the other sheets, i.e. relative to the other strips in the piles, in such man¬ ner that the picture segments on them become visible and to- gether with picture segments on at least one more displaced group of strips in another sheet form a continuous picture.
The word cassette as used herein is meant to de¬ note, an easily replaceable unit comprising a plurality of groups of strips, where the strips in each group are form- ing a picture and the strips in the different groups are overlapping each other in a louverlike manner and are mutual¬ ly displaceable by simultaneously moving all strips in one and the same group relative to all other groups, whereby edge portions of the strips in the group in question will become visible and together with edge portions of other dis¬ placed strips are adapted to constitute a complete picture.
In known cassettes, each strip is suspended in straps which are moved up and down by guide means which in timed periods are displacing picture carrying edge portions of the individual groups of strips into a visible position in order to display a number of pictures sequentially (cf. Danish Patent Application No. 369/70) . This method of suspending and moving the picture carrying strips is rather complicated, and has the effect that the cassette becomes rather thick, and that each individual picture must be com¬ posed of relatively narrow edge portions on three or more groups of strips, since each strip can only be displaced along a fraction of its height, because the strips of the different groups which together form a picture, with a view to an adequate control must overlap each other like persi¬ ennes or louvers, in the position of rest as well as in the position of display thereof..
Further, from U.S. Patent Specification No. 3,659,367 it is known to use two sheets, each of which is divided in a plurality of picture carrying strips by means of cutting lines which at their ends join a short cutting line situated perpendicular to the first cutting line in the marginal portion of the. sheet. By mutual dis¬ placement of the sheets two different pictures can be shown alternately, but it is not possible to produce a greater, number of pictures, e.g. 5 or 6 pictures successive- ly, by one single cassette.
It is the object of the invention to provide a relatively thin cassette of the kind dealt with, which is easy to produce and is easily replaceable and which is adapted to display a greater, number of pictures than hither- to possible, said cassette having strips which by simple guide means can be displaced safely over a substantial part of their height, preferably in such manner that only two groups of picture carrying strips are needed to form a whole picture.
Further, it is an object of the invention to pro¬ vide an apparatus having simple guide means for safe con¬ trol of the strip movements.
The cassette according to the invention is char¬ acteristic in that the cutting lines between the strips in a picture forming group in a first sheet at the marginal portions join openings which are all pointing away from the cutting line in the same vertical direction, and that the
2;IΓ_ cutting lines between the strips in a second picture form¬ ing group for the obtaining of the same picture all at their ends in the marginal portions join openings pointing away from the cutting line in a direction opposite to the direction of the first mentioned openings.
The simultaneously displaceable strips in each group are made by simple punching in a sheet, e.g. a sheet showing a complete picture, and the displacement of a group of strips is simply effectuated by displacement of the - sheet of which they form part, by means of guide means engaging the marginal portions of the sheets. The cassette that consists of flat sheets lying' upon one another, has a small thickness compared to the number of different pict¬ ures that can be shown, and because the openings in the sheets to be moved when showing a picture are pointing in opposite directions, it has become possible to show for instance 6 different pictures successively.
As the strips in two groups or two sheets can be mutually displaced over the entire strip height, a pre- ferred embodiment of the invention is characteristic in that the strips in those groups that together are forming a complete picture are arranged in only two sheets, each of which is carrying a complete picture on the group of picture carrying strips formed in the sheet. Since each picture to be displayed requires only two identical picture sheets or possibly only one picture, the picture forming segments of which are distributed on the two sheets and spaced from one another by a strip width, a saving as well as a re¬ duced cassette thickness are obtained when comparing with known cassettes containing three or more identical picture sheets for each picture to be displayed.
The openings at the ends of the cutting lines may for instance be isosceles triangles which can be .punched by a simple tool.
If desired, the cassette according to the invention may simply comprise'two sheets having oppositely pointing openings and each carrying its own picture, or possibly it may comprise a picture-less sheet and a single picture carrying sheet, but ordinarily it is made so as to show several, say five or six different pictures successively. According to the invention, this can be effectuated in that the sheets cooperating in pairs and carrying the same pict¬ ure are arranged each within their own. set of sheets, and that the openings in all the sheets in one set are pointing in opposite direction of the openings in all the sheets in the other set. By placing a preferably picture-less station ary front sheet in front of the sheets in each of the sheet piles, a secure guidance of the sheets with the pict¬ ure forming strips is obtained, and it has become possible to arrange an advantageous pause between the display of the individual pictures. According to the invention, the sheets with the picture forming strips may in their marginal portions have means, e.g. securing holes or clamps. Hereby it is ascertai ed that they will be correctly arranged in vertically move- able guide means in a display apparatus which according to the invention has corresponding gripping means to be couple to the marginal portions of the picture forming sheets.
The invention is explained in greater detail in th following with reference to the drawing where
Figure 1 shows a first front sheet in an embodimen of the cassette according to the invention,
Figure 2. shows a partial picture of a second front sheet in the same cassette.

Figure 8.a partial picture illustrating the re¬ lative positions of the strips in the situation shown in Figure 7. The embodiment to be described of the cassette according to the invention, has a. front sheet 1 which by a plurality of cutting lines 3 has been divided in picture- less strips la forming a group. At each end of the cutting lines 3 an opening 4 has been punched out, forming an isoscele triangle extending upwardly from the cutting line. As. appears from Figures 6 and 8. a number of picture carrying sheets (two sheets in the case shown) have been arranged behind the front sheet, said sheets being provided with strips lb, lc which in their initial position are lying directly behind the. strips la. These sheets are punched out in the same manner as the. front, sheet 1 in Figure 1.
Behind .this first-mentioned set of sheets a second set of sheets is located, the sheets having punched cutting lines 3 and triangular- openings 5 extending downwards from the corresponding cutting line 3 as shown in Figure 2. Be¬ hind the front, sheet 2 is. a picture carrying sheet having strips 2b constituting- a picture similar to the one formed by the strips lb in the first picture carrying sheet of the first set, and rearmost' is a second picture carrying sheet with strips 2c carrying a picture which is identical with the picture formed by the strips lc in the last sheet of the first set.
The cassette is placed in a display apparatus,not shown, having holding and guiding means engaging the margin¬ al portions of the sheets' and holding the front sheets 1 and 2 aligned in their positions shown in Figures 3 and 4, while the strips lb and lc, not. shown, in Figure 4 are extending analogous with the strips la to the right thereof, and the strips 2b and 2c, not shown, are extending analogous with the strips 2c and are lying between the strips la and 2a in Figure 4. The holding and guiding means can move the picture carrying sheets with the strips lb, lc, 2b, 2c in¬ dividually in vertical direction. The guiding means are actuated by a motor and programmed to move in such manner that after a picture-less screen formed-by the strips 2a, successively after each other follow a picture constituted by the strips lb and 2b and then a picture constituted by the strips lc and 2c, possibly with a picture-less screen between each picture. For the sake of simplicity it is here shown and described only how two pictures are alternating, but it will be understood that several pictures, e.g. six pictures, can be successively displayed, in which case a corresponding number of picture carrying sheets with piles of strips lying upon each other are provided. If desired, a cassette can also comprise more than two picture carrying sheets having cooperating identical pictures, each of which is divided in a group of strips. However, it is an essential advantage of the cassette according to the invention, that more than two identical picture carrying sheets for each picture to be displayed are not required. The guiding means in the displaying apparatus are advantageously provided with pinlike members adapted to engage corresponding apertures 6 (Figure 2) in the marginal portions of the sheets in order to ensure correct locating of the sheets in the apparatus. The marginal portions of the sheets could also be provided with clips or projecting lugs cooperating with gripping members on the guiding means.
When a picture corresponding to the one constituted by the strips lb and the strips 2b respectively, is to be displayed, the sheets are moving in the following manner: By an upward pull in the first picture carrying sheet in the second set of sheets, the strips 2b are moved up beyond the upper edges of the strips la in the first front sheet, so that visible display zones with picture portions appear as shown in Figures 5 and 6. Simultaneously or immediately after or before, the first picture carrying sheet in the first set of sheets is pulled upwards in such manner that visible picture segments on the strips lb will fill in the space between the visible picture portions of the strips 2b, whereby the complete picture will become visible, see Figures 7 and 8. It appears that it is the upper half of the strips 2b and the upper half of the strips lb that become visible, or in other words, the picture on the picture carrying sheet of the first set (behind the firs front sheet) must be displaced by the half height of a strip downwards relative to the picture on the picture carrying sheet with the strips 2b in the second set of sheets (behind the second front sheet) . It will be obvi'ous that the openings 4, 5, which behind the first set of sheets extend upwards from the cut- ing lines 3 and in the second set of sheets extend downwards from the cutting lines 3, may have other shapes than that shown, of an isosceles triangle. Further, it will be obvious that.the openings in the foremost set of sheets might point downwards from the cutting lines' and in the rearmost set of sheets might point upwards, from the cutting lines, whereby the strips in the. rearmost, set of sheets will extend down¬ wardly, and the displacement of the picture carrying sheets will be carried but in:, a downward direction. However, when a picture is illuminated by light from above, which most frequently will be the case, it is preferable that the cassette is constructed as shown in the drawing, because shadows from the free horizontal edges of the. strips hereby may be avoided.
Further, if desired, the sheets may be placed in an arbitrary oblique position or lying horizontally or with both- side edges horizontally, but in the same vertical or slanting plane and with the vertical or slanting strips being illuminated from one- side.
It will be understood that by the invention a flat cassette has been provided, in which the "sheets can be moved
-- so as to cyclically display a plurality of pictures as the sheets are driven upwardly and downwardly in reciprocating movements by guiding means engaging the marginal portions of the sheets.
