Matrix strips for photo printing machines.

The invention "relates to a die strip on a
Support frame of a photo printing machine.

The matrix strip according to the invention is used in connection with a photo typesetting machine, which is in the
above application is described. This photo typesetting machine takes excluded or non-excluded texts from any communication media, for example from magnetic tapes, punched tapes, keyboards connected by wire, telephone lines and the like

of coded signals representing the characters and has an output generally suitable for photo printing with excluded text, as he * when printing newspapers, books, magazines or similar printed matter should be used. The output part of such a photo typesetting machine can also be used for advertising purposes, registrations, Drawings and the like can be used.

The process of photo setting in which a drawing image from a rapidly rotating wheel or drum through a projection lens system to a fato-sensitive Material being directed has become an established technology. The ever increasing uses of photo typesetting machines and, the ever increasing demand for them also has the need for Improved construction of the storage elements of the characters allow them to grow. Along with the increasing number of uses The phototypesetting technology has also developed a need for an increasing number of different strips and types of characters developed. The versatility of a photo typesetting machine is due to the improved design of the matrix strips has been increased considerably, with little time and with improved reliability should be preserved.

A feature of the present invention relates to the positioning

Ren the matrix mark on a base film strip, which is precisely recorded by means of easily removable fastening elements attached to a die wheel, which allows a number of different types of strips to be used, which are selected as desired.

Another feature of the die strip is related onto the end plates attached to the corresponding ends of the die strip are attached to be hung on the holding elements of the die drum or the die wheel.

An additional feature are the clamping elements, which form part of the holding elements and which are suitable The die strip is tensioned on the drum keep. ·

The object of the invention is to provide a simple, reliable and low-cost die strip that can be produced provide a quick Allow stretching. The aim is to provide an improved training for the removable attachment of a die strip provided on the die drum in a photo printing machine will. In addition, the holding elements of the Ma- ' trim strip has improved durability and reliability gain. ■ - · '".'

Features and advantages of the invention will become clear from the following description.

In the drawing, an embodiment of the invention is shown for example, namely show?

Λ shows a representation of a die wheel arrangement and the elements for fastening the main die strip on the die wheel;

Fig. 2 is a side view of the die wheel with the! Fastening elements of the die strip on the bike; and

Fig. 3 shows a detail of the matrieenstreifens which shows the photographic images of the characters and the time slots *

As described in the patent application mentioned at the beginning is, a photo printing machine using a stencil strip is composed of a photo unit of three Main sections, namely a character display system, a projection lens assembly and a paper advance mechanism. The character display system has © in a continuously rotating die wheel, a xenon flash cylinder optical diffuser, a main matrix strip and fine photocell / lamp assembly or a matrix time generator on. The die strip has negative images or characters of one or more types and is on the surface of the Die wheel attached. The time slots or markings are arranged exactly alongside the matrix images »in such a way that that with the rotation of the die wheel the photocell arrangement

scans the slots to get information about character alignment to a computer, whereby the xenon flash lamp is triggered at the appropriate moment.

As can be seen from FIGS. 1 and 2, the die wheel 10 has a plurality of guide pins for the die strips, three of which are shown in FIG 18 in a precisely aligned position on the outer surface of the die wheel 18. The guide pins 12, 14, 16 extend through the corresponding guide openings 20, 22, 24 which are mounted in precise alignment on the die strip 18. One end of the die strip 18 is comparable with a metallic end plate 26 with holes 28 and ^30::; see, which are hooked into the respective holding pins 32, 34 which are in turn mounted on a block 36 of the tensioning mechanism 38 for the matrix strips block 36 is on. attached to the free end of the spring rod 40, the other end of which is attached to the die wheel 10 by a carrier assembly 42-.

The other end of the die strip 18 is hook-shaped End plate 44 is provided which is hooked into the wedge-shaped hook end 46 of the die wheel. The die strip 18 is in a sequence on the drum

3098U / 0Ö31

placed, the hook-shaped end plate 44 being hooked into the wedge-shaped hook end 46, the openings guided in the die strip over the guide pins 12, 14, 16 and then the end plate 26 is hung over the pins 28 and 30 securely. The clamping mechanism 38 for the die strip provides the necessary tension to hold the die strip in place on the die wheel. A finger hole 48 in the side part of the frame 50 can an actuation of the spring rod 40, whereby this by pressing the engagement of the pins 28 and 30 in the can support corresponding openings in the end plate 26, or vice versa, the release of these pins facilitated the openings. .

The die strip 18 is. preferably a strip a photographic film fixed in terms of dimensions, on which the negative time stamps 52 and the Negative character types 54 have been developed like this is shown in Figures 1 and 3. A typical die strip has 180 or more characters, which is sufficient to have two different matrices of types to be preferred to any die strip.-The time stamps 52 and the type characters 54 are translucent, with which a light, that is to be sent through this can pass through. The time stamps 52 are generally related to the individual type characters 54 aligned so that the necessary time

Signals can be sent to the computer, which creates the possibility of screening a selected character at the appropriate time and projecting it onto the line in a suitable alignment that is on the film
is set while the die wheel 10 continues to rotate.

The duty cycle that is used for the time displays
the calculator and for the projection of the image from the
Matrix strips on the photographic film is necessary is already described in detail in the above-mentioned application.
