Description

DETAILED DESCRIPTION OF THE INVENTION It is an object of the present invention to provide a device for proportional transfer of adjustable partial images of #A images onto images of small dimensions. Enlarged image of 41 photo (e.g. 9X155Is size)
Adjustable specific partial images of the negative (e.g. 24X56-
(size) K transfer is possible.

Conventionally, a method has been used in which the position of a partial image within an enlarged image is estimated without any auxiliary means, and then this partial image is marked on a negative.

This method is highly inaccurate. This is especially true because the person in the workshop who has to enlarge a partial image on the basis of marks on the negative has no direct contact with the person who originally specified this partial image.

The above objects are achieved by the present invention as follows.

That is, the areas for the m images are arranged on the base plate so that the horizontal edge of the area for the first image and the vertical edge of the area for the second image form an angle defining the ratio of the dimensions of the 9-size image. Sliders are provided on nine base plates, two of which are slidable in the horizontal direction, two sliders are slidable in the vertical direction, and each has a 10th side and a 20th side. and these sides form an angle with each other equal to 90° - the above-mentioned angle, and during sliding of the slider with respect to the above-mentioned area, the 10th side respectively passes over the first image and the 20th side is arranged so as to move over the second image.

Thus, according to the invention, a simple device is provided in which, for example, a photograph is placed in the area for the first iii is provided.Moving the adjustment slider to 5 such that the tenth side defines the desired portion of the photo,
The "second" side is proportional to the size of the format and moves to define the reduced area in the negative. Once the desired partial image has been established on the magnified image and the negative, it is easy to mark the negative or the frame surrounding it with a plumb line. Therefore, the relevant instructions are clearly established for the workplace.

The invention can also be used whenever a particular portion of a format consisting of a graphic design or advertisement is to be reproduced as a corresponding portion of another format.

The slider itself is made of cardboard with cutouts punched out, transparent plastic with opaque printing on the entire surface except for the part corresponding to the cutouts, plastic made of opaque material with cutouts, plastic made of opaque material with punched openings, and rotating. Made of plastic or metal with sides made of free strips.

Next, two embodiments of the present invention will be described based on the accompanying drawings.

In the apparatus shown in FIGS. 1 to 5 [.

A slide 3.4 or a slide 5.6 is guided in the two guide elements 1 and 2. Slider 3 to 6
is provided with edge plates 3' to 6' by means of which the slides 5, 4 can be moved relative to each other horizontally and the slides 5, 6 relative to each other vertically. A composite body 50 consisting of guide members 1 and 2 is pivotally connected to the base plate 8 by means of a joint 7.

You can flip it open like a book.

Between the composite 50 and the plywood 80 the photograph 20 and the negative 21 5-6 have cutouts exposing areas 9, 10 at the position of the slider in FIG. Excluding the part corresponding to the cutout [
If the slider is made of a transparent material printed on the entire surface, a cutout can be formed. Alternatively, the slider may be made of an opaque material and the cutout may be an opening (FIGS. 5 and 7). For clarity, all cutouts or openings are designated 9.10 in FIGS. 1-4.

Figures 5a, 5b, 7a and 7b show opening 1.
Sliders 3 to 6 with numbers 1 to 17 are shown. The openings 11 to 17 are defined 5 so as to expose one area 9 and 10 in the position of FIG. 1, ie in the position in which the adjustment slide is fully inserted into the guide member 1.2.

At that time, the left side 121 of the opening 12 (slider 3) is the area 1
The side edge 108 and the lower edge 121 or the upper edge 121 of 0 coincide with the lower edge 103 or the upper edge 10'' of the area 10.

The lower rectangular area of the opening 13 (slider 4) is separated from the area 9, and the upper side 131 and the upper side 1♂ of the area 1o coincide.

Open Q, 14.16 coincides with area 9. Also, the opening 15 (
The left side 1p of the slider 5) coincides with the side 101 of the area 1o. The side 174 of the opening 17 (slider 6) is the end @ 1
Matches 0'.

In FIG. 6a, the two slides 3.4 overlap in the position of FIG. 1 (without guide member 1.2). Upper slider 3
, openings 11 and 12 are visible. Regarding slider 4 below it.

Only the side 134 is visible, which side 154 together with the opening 12 forms the area 10 .

'limb diagram shows adjustment sliders 3°4 offset relative to each other. The left side 13m of the opening 13 (slider 4) is inserted into the opening 11 (slider 5).

The length of the section is thereby the length according to Figure 6a! Alt is shortened compared to a. Similarly, opening 13 (
This is because the edge 151 of the opening of the slider 4) is visible inside the opening 12 (slider 3).

The height of the cutout is reduced to b' compared to b in FIG. 6a. During this change in the cutout, the following holds true: a = b : b'.

Converting the height g of the image to the height g' of the cutout A.

8a and 8b for the conversion of the height h of the image to the height h' of the cutout B. That is, g:g=h:h' holds true.

Therefore, when assembling the device, it must be considered that the riders 3 to 6 overlap as shown in Figures 5 to 8. For example, if Figures 6b and 8b are superimposed, the first Cutout defined by a and h for area 9 in the figure.

In area 10, a cutout defined by g and b is visible in the opening of groove 2.

FIG. 9 is for explaining the geometrical relationship and corresponds to a GSB diagram, and shows the opening 13 of the slider 4. From this figure, b/a=-α can be derived. From this, a = arcgll(bO) a is the length of the area 90 size, and b is the length of the area 10 size. Reduction from 1 to 0 corresponds to reduction from b to O. The same is true for the value g and h.

Further, β=90°−α holds true. This is the corner of the two sides of the slider that simultaneously define the large 1 and small 1 part images. In other words, in Fig. 9, the sides 1ji and 151
forms an angle β, while.

In Figure #11, horizontal side 91 of area 9 and vertical side 1 of area 10
An angle α is given between G''. The concepts horizontal and vertical each relate to the diagram.

It is particularly simple to transfer the partial image of the image 20 formed by K in this way to another image 21.

FIG. 10 shows a second embodiment. Post 31 on top of base plate 8
, 52.33, the guide rod is attached. Sliders 54, 55, 40° 41 are slidably disposed on these guide rods by means of sleeves. Member 34' to the slider by means of couplings 56,57.

55', 4 G', and 41' are fixed. The angle α can be adjusted arbitrarily. To increase variability.

An adjustment mechanism 46 can be provided in the vertical portion of the adjustment slider.
