Description

Frame for slides

The innovation concerns a frame for slides.

Such frames are in various embodiments in Commercially available, but they are all only suitable for a very specific slide size. For different slides ic iv formats therefore also result in different slide frame formats.

In order to be able to show slides of different sizes with a slide projector, adapter frames are already known in which framed small slides can be exchanged or permanently inserted. This is exemplary refer to DT-GM 1 819 584. So should slides of different formats in a single one To demonstrate a slide projector, several different types of slide frames must be used.

Is is therefore the task of the innovation to eliminate this disadvantage and the use of different slide formats to simplify.

The solution to the problem is contained in the claims and is described in more detail with reference to the drawings.

Hs show:

1 shows a slide frame according to the invention in which a Normal format slide taken between cover glasses is;

2 shows a slide frame according to the invention in which a framed Klcindiapositive is received.

ρ who the frame according to the innovation consists of the two frame parts 1 and 2. In the frame part 1 there is a first recess 1a, the dimensions of which are length, width and thickness of the normal format slide lying between the two cover glasses 3 4, so that it is centered in position in the recess 1 a and held by the frame part 2 will.

A second recess consists of parts 1b and 2b, part 1b being in frame part 1 and part 2b in frame part 2. The framed small slide 5 is inserted into this recess and its position is centered. By dividing the second recess on both frame parts 1 and 2 is achieved that the film image 5a of the small slide 5, the frame slightly thicker than the normal format slide 4 and its cover glasses

3 is in the same plane as the film image of the normal format slide 4 arrives. As a result, the image sharpness does not have to be on the projection lens when both image formats are shown mixed be adjusted. The two frame parts will be

Because of the new framework for slide, it is open advantageously possible to use different slide formats with a single frame that is the same for both formats, so that they can both be used in a standard format projector are demonstrable.

Claims (4)

- 4 - Talk to Schut 1. Frame for slides, characterized that it has a first recess (la) for a preferably lying between cover glasses (3) Normal format slide (4) and a second recess (1b, 2b) for a framed small slide (5). 2. Frame for slides according to claim 1, characterized in that that the recesses (1a, 1b, 2b) in their Dimensions of the length, width and thickness of the normal format slide (4) and its cover glasses (3) or the framed Kleinuia positive (5) correspond and thereby cause the position centering of the film image (4) or the small slide CS) used. 3. Frame for slides according to claim 1 and 2, characterized in that the frame consists of two frame parts (1) and (2) and that the second recess Ob, 2b) partially in the frame part (1) and partially in the frame part C2) so that the film image (5a) of the small slide (5) in the same plane as the film image (4) of the normal format slide (4) arrives. 4. Frame for slides according to claim 1 to 3, characterized in that that the two frame parts (1, 2) are joined together by a plug connection (1c / 2c).
