"Information carrier for use in a device for the visual perception of still images".

The invention relates to an information carrier for use in a device of the visual perception fcon still images, which is used as a book with a fixed front and back Cover is formed, which are connected by a hinge connection, wherein between the cover one or more information-carrying elements in the hinge connection Sheets are pivotably arranged. Such information carriers are known and are used for storing slides that are on the informa-

mation-bearing sheets are arranged removably so that they are projected ^ by means of a projector can. Special devices in the form of a light box are used to view slides stored in the carrier known to be between an information-bearing sheet that one wishes to look at and an underlying sheet Sheet can be inserted.

These known information carriers are suitable not for this, in a simple manner in such devices for the visual perception of still images that are of the projector type and with incident light, such as with an epidiascope or with transmitted light, like a writing projector, the images of one on the projection surface of the projector placed information-bearing sheet visible on a screen.

An information carrier is already available for use in such devices of the projector type has been proposed that has two hinged covers and in which the information-carrying sheets with the extending parallel to the hinge connection of the cover covers free edge of one of the ceilings are pivotally connected. This well-known information carrier cannot be used with projectors that have a projection surface without additional aids

are provided, the dimensions of which are essentially those correspond to the information-carrying sheets, because this information carrier in such projectors cannot be adequately supported due to lack of counterweight. As one such aid is mentioned at Information carrier therefore a separate proportionate Heavy frame used as a counterweight that is placed on the projection surface of the projector and to which the information carrier can be clamped.

Oils invention aims to provide an information carrier in which the use of the above rather expensive frame is unnecessary. The invention is characterized in that the back cover of the information carrier is attached to that of the Hinge connection facing away from the free edge is provided with a fold-out support element which is pivotable about an axis extending parallel to the hinge connection and has a rigidity which is at least so large that the support element is free when it is wedged in the unfolded state Edge can bear the weight of the information carrier. This measure ensures that the inventive Information carrier used in a simple way can be “>” only visually perceptible with a device arranged on a wing.

making of still images, which has a projection surface that is higher than its base surface, onto the one or more information-bearing sheets can be placed for projecting. Such a structure, on the invention also relates, is characterized in that the free edge of the unfolded Support element of the information carrier between the base surface of the device and the support surface which this is placed, is pinched and the covers and the information-carrying sheets lie obliquely against the device, the hinge connection of the cover covers at the level of the projection surface is located.

In a structure of this type, the device used for projecting itself serves as a counterweight and it does not need any special tools in the form of a frame or the like. to be used.

A preferably used embodiment of the information carrier according to the invention is thereby characterized in that between the rear cover and the information-carrying sheets at the hinge connection an attachment with a fold-out part is attached, with between the attachment and the fold-out Part of the information-carrying sheets can find an edition.

Such an intent offers advantages if

the information carrier in a structure of the above Type used in which the device used for projecting is provided with a ventilation opening is provided, which lies in a wall of the device against which the covers as well as the information-carrying The leaves come to the plant at an angle. Before the projection, these sheets of paper lie on the covers, after the projection underneath, so that the leaves could close the said ventilation opening. This is avoided by the above-mentioned intention. This resolution also has the advantage that it can be useful when carrying information Sheets can be viewed without a projector. If the latter sheets are transparent, the fold-out one can be Part of the header can be pushed under such a transparent sheet, so that the information is clearly visible on this transparent sheet. The fold-out part of the attachment has it then preferably a light color.

An embodiment of the invention is illustrated in the drawings and will be described below described in more detail. Show it:

1 shows an information carrier in book form in the closed state,

FIG. 2 shows the information carrier according to FIG. 1 when open,

3 shows an illustration of the information carrier after. Figure 1 in the folded state, which is assumed for projection purposes,

FIG. K shows an illustration of the information carrier according to FIG. 1 together with a projection device on a support surface, the device and the support surface being only partially shown.

5 shows an illustration of the structure of an information carrier according to FIG. 1, with a writing projector,

6 shows the structure according to FIG. 5 in a state in which information-bearing sheets are changed,

The information carrier according to FIGS. 1, 2, and 3 has the shape of a ring binder 1 and contains a

fixed front cover 2 and a fixed rear cover 3 'which are connected to one another by a ring hinge h. A number of information-carrying sheets 5 and an attachment 6 are attached to the ring hinge k. The information sheets 5 are transparent. The attachment 6 is provided with a fold-out part 7. Between the sheet 6 and the part 7, the information-carrying sheets 5 find a place to lie in the closed state of the bag. In order to view transparencies without using a projection apparatus, the part 7 of the attachment 6 can be found under

one or more of these banners are pushed. Part 7 has a light color for this.

The back cover 3 is provided with a fold-out support element 8, the rigidity of which is at least so large that if the free edge 9 can bear the weight of the information carrier 1.

In Fig. 4, the information carrier is after Figures 1, 2 and 3 in this way between the base surface 10 a projection device 11 and a wing 12 pinched. The wing 12 is the plate here of a table 13-

The projection device 11 has a projection surface 14, which is higher than the surface 10, and a ventilation opening 15.

The support element 8 carries the cover covers 2 and 3 »the information-carrying sheets 5 as well as the intent 6. The information-bearing sheets 16, which are on the covers 2 and 3, still have to be projected, the sheet 17 is in Projection position and the sheets 18 have already been projected. The sheets 18 are between the Attachment and its fold-out part 7 · The part 7 avoids that the leaves 18 the ventilation opening 15 lock.

In FIGS. 5 and 6, the inventive
