[0001] The present invention relates to a refractive viewer, particularly for currency conversion
tables.
[0002] It is known that pocket or desktop viewers are widely used which allow to alternately
view a first image and a second image which are arranged on a same backing element
and above which a lens is arranged.
[0003] The movement of the backing element or its inclination allows to view one image or
the other alternately, according to the user's requirements.
[0004] These devices are generally used as advertising gadgets, gifts and the like.
[0005] These devices are usually limited to having only a first image and a second image
which are mutually superimposed and can be viewed alternately.
[0006] The need is currently felt to have practical devices for performing currency conversions
and in particular conversions from the current currency to the euro, which will soon
become the only currency throughout Europe.
[0007] Calculators for performing conversions from one currency to the other are expected
to be used to perform these conversions, which are initially indispensable to avoid
disorienting consumers.
[0008] However, this system can be rather impractical and most of all it has a cost which
must in any case be considered.
[0009] The aim of the present invention is to provide a refractive viewer, particularly
for currency conversion tables, which allows to obviate the need to have a calculator
available in order to perform said conversions.
[0010] Within the scope of this aim, an object of the present invention is to provide a
refractive viewer, particularly for currency conversion tables, in which two or more
images are available on the backing element of the viewer.
[0011] Another object of the present invention is to provide a refractive viewer, particularly
for currency conversion tables, which has an extremely limited cost.
[0012] Another object of the present invention is to provide a refractive viewer, particularly
for currency conversion tables, which has reduced dimensions and a very limited thickness.
[0013] This aim, these objects and others which will become apparent hereinafter are achieved
by a refractive viewer, particularly for currency conversion tables, characterized
in that it comprises a backing element on which a plurality of images are printed,
a lens being arranged above said supporting element, said plurality of images providing
currency conversion tables.
[0014] Further characteristics and advantages of the present invention will become apparent
from the following detailed description of an embodiment according to the invention,
illustrated only by way of non-limitative example in the accompanying drawings, wherein:
Figure 1 is an exploded view of the viewer according to the present invention;
Figures 2 to 4 are views of an example of currency conversion tables meant to be applied
to the backing element of the viewer according to the invention.
[0015] With reference to the above figures, the viewer according to the invention comprises
a backing element 1 on which a plurality of images are meant to be printed; three
of said images are shown by way of example in Figures 2-4.
[0016] Said images illustrate tables for converting currencies from lire to euro, with calculation
of the equivalent value.
[0017] The images are printed so as to be mutually superimposed so that the lines of one
image are alternated with the lines of the image that lies below it.
[0018] In practice there is no exact limit to the number of images that can be printed in
superimposed fashion on the backing element 1.
[0019] The only limit is set by the fineness of the printing that can be achieved.
[0020] On top of the backing element 1 with the images printed thereon there is provided
a lens 3 which is meant to alternately reflect, by refraction, the images 2 printed
on the backing element 1.
[0021] Figures 2-4 and particularly Figures 2 and 3 illustrate the currency conversion tables
from lire to euro; each table is divided into three sections, each of which is in
turn divided into subsections. The subsection 4a lists the equivalent value in lire
from one hundredth of a euro to two euro, while the second subsection 4b lists the
equivalent value in lire from 5 euro to 500 euro.
[0022] The intermediate section of Figure 2 illustrates, in the subsections 4c to 4f, the
equivalent value in lire from 0.01 euro to 1 euro.
[0023] Finally, the subsections 4g and 4h illustrate the values in euro that correspond
to 50 Italian lire to 100,000 Italian lire.
[0024] Figure 3, which must accordingly be superimposed on Figure 2, has sections 4a-4h
which correspond to the sections 4a-4h of Figure 2.
[0025] Figure 4 instead illustrates the table for conversion from euro to French francs,
from French francs to euro and the calculation of the equivalent value in French francs
with respect to the euro.
[0026] Accordingly, the alternation of the various figures or images printed on the backing
element 1 allows to perform a quick conversion from one currency to the other according
to requirements. The conversion tables are of course not limited to the above-indicated
currencies.
[0027] As mentioned, it is of course possible to superimpose a plurality of images 2 on
the backing element 1, thus allowing various possibilities for conversions or other
calculations.
[0028] The viewer according to the invention can therefore be used as a portable calculator
which is undoubtedly very inexpensive and simple to use.
[0029] In practice it has been observed that the viewer according to the invention fully
achieves the intended aim and objects, since it allows to eliminate the need to use
a pocket calculator, thus allowing a considerable saving of money together with very
simple use, making the viewer highly desirable from the point of view of the consumer.
[0030] In practice, the materials employed, so long as they are compatible with the specific
use, as well as the dimensions, may be any according to requirements and to the state
of the art.

application claims priority are incorporated herein by reference.
