Abstract

The slide viewing cassette (1a,b) is intended for small-size slides, particularly pocket slides (6). It comprises a frame (5) in which the slides are arranged at pre-determined positions. The cassette is inserted in a viewer, which is provided with means for sliding the frame so that any slide in the frame can be moved into the viewing position. The viewer may be provided with its own viewing screen or it may have a lens for projecting the slides on to a separate screen. The cassette may have two transparent panels (4 is one) connected by a hinge (2), the frame (5) surrounding one panel and projecting above the plane of that panel to form a space in which the slides are contained.

Description

Slide viewer

The invention relates to a small format dis-viewing device Slides, especially pocket slides.

Slides are used both for private purposes and in the commercial sector used in large numbers. Slide projectors are used to view slides and in the latter At the time, there were also more and more screen devices in the manner of a micro-image reader.

Both for slide projectors and for display devices, the Slides can be inserted into special slide-msgaziné one behind the other.

The magazines are either straight or annular.

The known way of storing slides in storage has numerous disadvantages. Benn a specific slide can be selected from a large number of slides in the magazine then the slides must either be lifted from their magazine until that a text field is visible on them, or completely removed and be held against the light.

This work is quite tedious and time consuming.

Practice has also shown that it is very easy for individual slides to be mistaken reversed or even placed upside down in the magazines will. Handling slides becomes particularly uncomfortable when it comes to this small-format slides, so-called pocket slides, because they are small because of their small size Size can only be handled with considerable skill.

Today's slide viewing devices have due to the used Din magazines also have the serious disadvantage that with them basically only Slides can be viewed in the order in which they are sorted into the magazines are. If, for example, a dis is to be shown several times during a lecture, it must either multiple times in the magazine, or the magazine must each time back to the desired slide, which is time consuming and it can be traversed makes it difficult in practice, then the correct position of the magazine again for the further dis-demonstration to be found.

The invention is based on the object of a dis-viewing device to develop, which simplifies the handling of slides in slide magazines and With the slide, it can be presented in any order without any major expenditure of time are.

This object is achieved according to the invention by what is specified in claim 1 Measures gels, in the slide viewing device according to the invention, the slides simply placed side by side in micro-image cassettes when framed. The micrograph cartridge is so large that it can be handled comfortably. The single ones Slides can be easily identified by viewing the photomicrograph as a holding everything against the light.

Incorrectly arranged slides can thus be easily seen at a glance to recognize. Labeling can also be seen on the slides without having to these - as with conventional «magazines - add this to the magazine or

must be removed from the micrograph cartridge.

The invention makes archiving pocket slides very easy. A single micro-image cassette can hold twenty slides, for example, and thus a special one Subject to be provided. This microimage cartridge can be used together with other microimage cartridges be stored in a conventional microphotograph cartridge container. Regarding archiving the same advantages as when using Microfiches without the disadvantage of lower image quality due to microfiches to obtain the necessary photocopying of an original.

In the slide viewer according to the invention, the slides are in front Dust and dirt and protected from scratches stored in the micro-image cassette, this avoids the defects that occur in the unglazed slides commonly used today will.

It should also be emphasized that it is with the slide viewing device according to the invention it becomes possible to carry out spatial archiving in the micro-image cessettes. In the first horizontal line of each cassette, e.g. slides can be arranged in a logical Be arranged in order, while in the vertical lines such slides which are logically subordinate to the slides of the first line. In parallel Lines can e.g. also be kept in two parallel slide series, so that when looking at the slides you can jump from line to line. This makes sense, for example, when two plants grow over time with two dis-series should be documented and compared with each other.

In the slide viewing device according to the invention, it can be either be a screen device or a projector.

The micro-image cassette of the slide viewer according to the invention is particularly easy and cheap to produce by the features listed in claim 4. This embodiment has the advantage that the slides are pushed back and forth on the plate until they are in their correct position. If less Slides should be arranged in a micro-image cassette as a maximum of can be attached to it, slide frames without a picture, so-called dummies, can be used as be placed in the spaces of the micro-image cassette, so that all slides through the frame of the plate are firmly fixed.

According to the embodiment of the invention characterized in claim 5 However, the use of dummies can also be saved.

The measures characterized in claim 6 enable a fixed Order of showing slides. Just like a carousel magazine, the At the end of the presentation without a break, the presentation of the first slide started again which is often a requirement for advertising purposes. The ease of use a slide viewing device is particularly large by these measures, since it is for one is possible by pressing only one button the Slides in one to consider the given sequence, but also very quickly from the Deviated from the order and jumped back or forward to other slides can.

The drawing shows instead of the entire slide viewer a replaceable micro-image cartridge for the device.

FIG. 1 shows a micro-image cassette designed according to the invention in the unfolded state with inserted pocket slides, FIG. 2 a section through the micrograph cessette according to Figure 1 in the closed state.

The micro-image cartridge 1 shown in Figure 1 consists of two means a hinge 2 interconnected parts 1a and 1b.

In both parts 1a and Ib a plate 3 or 4 made of glass is held, The plate 3 is bordered by a frame 5 in part 1 a, which is slightly Above the plane of the plate 3 protrudes. This enables framed slides 6 on to lay the plate 3 in such a way that the area bounded by the frame 5 on the plate 3 is completely covered.

If fewer slides 6 are available than can be accommodated on plate 3 the empty spaces with slide frames without picture, so-called dummies 7, be filled up.

By swiveling the part Ib, the plate 4 lies on the individual Slides 6 or the dummies 7, so that they are fixed and the micro-image cassette 1 is then ready for archiving or for insertion into a slide viewer.

Not shown in the drawing is an embodiment of the micro-image cassette, in which a grid is provided on the plate from Clas 3, through which the position of the individual slides 6 is set. That way, the need of There is no need to use dummies.
