DE1547630B2 - DEVICE FOR CONTINUOUS VISUAL DISPLAY OF INFORMATION - Google Patents

Description

The invention relates to a device for the continuous optical display of information in Form of letters, numbers or strings of characters with two endless chains on which a multitude of panels are fastened close together.

Optical display devices for the continuous display of information, such as Stock exchange rates, prices, news or the like are known. In a known device this Art is used to move light sources in the arrangement of the information to be reproduced in the form of a tape on a certain path. Another known display device consists of several Pairs of endless, revolving chains on which a large number of panels are attached close to one another, the arrangement being such that the individual panels as the chains circulate one after the other in one The viewing opening through which you can read the information on the boards can. These known devices are structurally complex and work relatively slowly.

It is customary to display the stock exchange prices on secondary stock exchanges according to the Main exchanges to display trades that have been carried out. The transmission devices used here (Radio, teletype, etc.) work at a very high speed. Mechanically controlled display devices are usually unable to process incoming information at the same pace to convert into display signals. For this reason, high-speed printers are often used in these cases, which the Print incoming information onto a tape from which the information is then projected. While these displays are relatively fast, they are usually slower than most of the signaling systems used to convey the information.

The invention is based on the object of a device for the continuous visual display of Information in the form of letters, numbers

In the extinguishing station you can these disks from a first stop position all valves of the gas or liquid nozzles one parallel to the board by 180 ° in a second stop common control, so that in position pivotable and on one side with one of the extinguishing stations all panes in the sense of an extinguishing dark, light-absorbing surface and the rotation are applied, independently other side with a reflective or fluores ^ 20 of whether the discs are turned upside down for erasure decorative surface are provided, while the must be on or already in the extinguishing position the outside of the endless chains lying tops.

The surface of the panels is either equal to one or the gas or liquid nozzles of the writing station is the same as the other side of the discs, and through and the erasing station can be mounted on a common one erasing station and one writing station, both of which are pressurized medium chambers,
If the controllable valves are electromagnetic chains arranged at right angles to the direction of motion of the endless series of gas or liquid valves, it is expedient to provide that the keitsdüsen exist, which are provided with controllable valves on a valve disk in closing by means of a spring. Position guided swivel arm is attached and that

Messages in the form of letters, numbers or characters correspond to the relevant disks, pictorial representations or the like. Are turned over at 25 and thus the desired sign device according to the invention is generated by depicting 5 on the board. Of course, certain panels 25 can be turned over, so that the reverse is also possible and all disks 25 turn their luminous, light surface 30 on the blackened panel 11, which does not match the contour of the zen background of panels 11 or their dark desired characters correspond, so that the surface 31 appears on the brightly shining, reflective characters in a negative image on the board formed underground of the boards 11. io appears. If you open the panes in FIG. 8, for example, if none of the nozzle valves were turned in the upper part of 25 at the writing station 42, left panel 11 those disks 25, then all disks 25 remain in the erasing position, which result in the contour of an "M". The disks 25 from FIG. 6 it can be clearly seen that the notes in the lower part of the right panel 11 are stored in such a way that the two ends are turned so that the 15 or stop positions, the focus of the image of the fraction " ³ / s", appear on the front of the panel . It is generally disks offset from the axis of rotation 27, common practice to display the letters above the numbers, so that the disks 25 remain in the two end positions under the action of them, although the system according to the invention does not have any dead weight. Way is limited to this. Even if the disks are extremely light, the rotation of the disks 25 acts on the ones shown schematically in FIG. 6 20 still a torque on the disks, the manner shown with nozzles 35 and 36, which either strives to hold the disks in their stop position on the back or on the front of the end. From Fig. 6 it can be seen that the upper loose tape is arranged, namely directly nozzle 35 directs its nozzle jet against the upper edge before the panels 11 of the tape in the view of the upper disk 25. The result is that the area 20 enter. 35 disk 25 around their bearing pin 27 as a rotary

The valve mechanism described represents an element which is exposed to the first nozzle jet 95 (see FIG. 9) and which acts quickly and reliably, and which becomes 35. This has the effect that the disk 25 can be used in many ways around it. The application is not pivot bearing 27 is rotated until the disk is limited to the case described here, where, on the basis of Bernoulli's laws, essentially numerous nozzles are controlled; you can borrow the one parallel to the plane of the jet. Valve mechanism even with only a single nozzle If one only had a single jet of nozzles, use any control to provide 40 it could happen that the disc after you watch. The medium ejected from the nozzle that comes out of the effective area of the nozzle is usually air or another gas that falls back in the wrong direction of rotation. Therefore, in some cases, for example during mixing processes, to ensure that the disk in the erasing station can also be a liquid from the liquid from the one shown in FIG. 9 are shown in solid lines. 45 th position further into the position shown in FIG. 6 depicted

No speed control has been rotated here, in which the lower edge of the drive for the panels 11 is described. As the disk 25 rests against the side 39 of the board 11, no specific relationship has been given between a second nozzle 97 (FIG. 9) on the path of movement of the board drive speed and the speed of the endless belt, which, however, is indicated in terms of with which the nozzles for adjusting 50 the direction of movement of the endless belt by approximately one of the disks in one of their end positions are actuated half the disk diameter with respect to the nozzle 95. In preferred modes of application, it is offset. Therefore, the air jet exiting the second nozzle at a speed through the 97 can move the leading edge of the viewing area 20 that takes up the speed of the disk and causes it to correspond to the speed at which the letters are hung on the 55 regardless of the speed of movement Wishes to reproduce panels. Speed accomplished. The second nozzle 97 is opposite to its controls, which are normally arranged perpendicular to the disk 25 so that they are associated with received signal energy which is directed to the partially rotated disk at a point on adjustment of the particular disk parts below that between the underside of the disk and instantaneous control can be used. It 60 is the center of gravity 27. This is sufficient to admit that the control signals have the effect that the disk ends its half turn full-generation of the reproduction of the message normally and into the in the upper part of FIG. 6 are binary coded signals in ID cards.

There are so many pairs of nozzles 95 and 97 devices you can set the speed of the panels provided in a vertical row as slices according to the speed in the vertical rows of the panels before which these code messages are received. hands are; the number of pairs of nozzles 95 and 97

thus corresponds to the number in FIG. 1 illustrated outlets 45. The extinguishing nozzles are used to all Turn the discs in the same position.

According to another embodiment, one can instead of the two nozzles 95 and 97 in the extinguishing station perform the desired rotation of the disks with a single nozzle for each disk 25, wherein this single nozzle has a substantially rectangular outlet and below one

Angle is arranged that the moving disc initially at a point above her Axis of rotation is acted upon by the jet, whereupon when the disc is partially rotated and the panel has been moved further in relation to the nozzle jet, that part of the nozzle outlet is more effective is located in the area of the rotary disc bearing; this then causes the disk to rotate accomplished.
