DE1835207U - FOLDING MASK FOR SEPARATION IMAGES (DIAPOSITIVE, ETC.) WITH ADDITIONAL WINDOWS FOR IDENTIFICATION OF THE IMAGE - Google Patents

Description

Designation of GBRAUCH S. MUSTLRS: Folding mask for transparencies (slides, etc.) with additional windows to identify the image.

So far there are folding masks for different formats in different designs, in which the respective film portion or any other image carrier is covered to such an extent that only Lich the image surface reaches the projection.

The labeling (designation of origin, image content, serial number; Date and / or other information) was printed on the picture frame and / or on the picture mask housed.

The following l '-' lengths 1 appear unpleasant when writing on transparent images (slides, etc.) provided with folding masks: 1. Labels of any kind can be used in the image projection cannot be projected without further ado. 2. In the case of full-format representations, iz » Labeling cumbersome and time-consuming assembly required. ci 3. The size of the size is reduced by subsequently carried out font montages compulsory and as the field available for the picture, so that the s rid Fiä Possibility of cropping the field fully for figuratively To exploit representation. 4. It is often difficult to do the lettering afterwards u To insert montages without adding essential details to the picture cover up or lose. Since bilayer in the formats which mitlappmasken be shifted, mostly already from the one shown If the object is completely filled out, a font assembly is usually omitted. In this way, however, another significant disadvantage arises: 5. In the case of lectures, the presenter, the audience and sometimes also the screener have no control over what is shown due to the lack of labeling, which is the worse the less they are individual representations differ from each other and the larger , ros, is the number of images shown. 6. At:. see-through images provided with flaps (slides, us W.) the co-projection of the designation of origin and other information, which is valued for larger glass pictures without folding masks, must be omitted if the defects already listed above are not to be accepted.

7. A deficiency that is independent of labeling problems is that the folding masks commonly used up to now allow neither optical nor electrical scanning for documentation and / or sorting purposes. The task consists of labels and / or designations without making the listed deficiencies possible, as well as in the constantly growing collections of transparencies (slides, etc.), the folding masks and thus the transparencies provided with them are accessible for optical and / or electrical scanning for documentation and / or sorting purposes close. (In the following, "marking" is summarized for "Labeling, designation, documentation and sorting symbols" The solution is based on the consideration that the commercially available image projectors easily illuminate a larger area than the one that was previously released by the folding masks. To solve the steep task while avoiding the mentioned 1-1 Disadvantages it is proposed to create another small window or several other small windows outside the usual window. It does not matter what kind and in what way the - ZD Identification takes place within a window.

According to the proposal, z. B. a rectangular additional Window carry out the same marking of the transparencies as they are in the large formats is widespread, but in contrast to these without the picture window to zoom out.

Rather, this is available for recording the image without any restriction. This eliminates the need for time-consuming tasks. days that were required when labels in the y f should be housed. Also it can no longer happen that essential image details are covered by the marking. The presenter, the audience and sometimes also the projectionist are able to check what is shown on the labeling: in a factual and projection-based (upright and laterally correct image) respect, and, depending on other information, to find out about the origin, date, etc.

For optical and / or electrical scanning for documentation and / or For sorting purposes, additional small windows can be useful on the folding masks Shape and size are provided.

The additional windows for holding labels of all kinds can either already be present in the mask or only after inserting the Image carrier inserted by using a punch or other suitable aids and then be used in the manner shown.

The additional windows can also be created directly in letter shapes will. For example, a letter punching device can be punched directly through the mask and the edge of the film Create letter window.

The additional windows can be used for dimming and / or the information / or. Documentation with material of the desired transparency and Color are covered.

The execution of the marking can be done in any way, e.g. B. handwritten, with a typewriter, by printing, stamping or phototechnical processes. material with / for identification can also be carried out by phototechnical and other processes and, if necessary, in the designated areas at your own request additional window can be introduced.

The material for marking can be, for. B ,. with a mask for a 5 x 5 cm (= external dimension) slide also by enlarging the light-colored, mostly white part of the mask to 5 "6 cm compared to the unchanged (= 5 x 5 cm) black or dark-colored part are available, whereby in this case the 1 cm protruding z current share (light-colored / white) in the usual format limitation) Eg 5 5 cm, pinched, over which the additional window can be folded and in the area of the additional window can now be used directly without foreign material for lettering or masking.

In this example, the external dimensions are again 5 x 5 cm.

The following examples are intended to explain the solution: Figure 1 shows a hash in which "Fe" is the usual window for the image, "zFe" is an additional window for identification and "Fi" is an image-bearing part of the film, the lower perforation of which is in the area of the additional window is removed. "Ha" puts here ready attached to the mask, transparent material on which the marking can be applied in any way.

As another example, Figure 2 contains two additional windows, which allow further labeling to be projectable.

Example 5 shows a folding mask that has an additional window for Labeling and another group of windows for optical sorting.
