Display device

The innovation relates to a display device for the cellular display of characters with a rotating character carrier, on the lines lying next to one another parallel to the direction of rotation, signs are attached which when passing through a display field independently by means of a lighting device that is arranged behind the carrier and can be controlled in a rotationally synchronous manner are briefly illuminated from each other.

By the German utility model 7 301 97I is an advertisement; device is known in which on a rotating about its longitudinal _axis: Symbols are attached cash drum, which are connected by a V angle of rotation synchronously controllable lighting device illuminated. The symbol symbols are always illuminated at the moment when the desired symbol passes through the display field. If the drawing drum is rotated at a correspondingly fast rate, a stationary image of the line of symbols is created. I.

The present innovation is based on the task of providing a wide |

tere improvement of the known display device to achieve | and also a flat display of several lines at the same time

to enable. \

According to the innovation, this object is achieved in that the Zei-. chträger is designed as an endless belt driven by two rotatable cylinders about its longitudinal axis. The tape can

according to the innovation be a film strip on which the lines;

I are attached by photographic means. The characters can f

as translucent areas in the otherwise opaque strip or as opaque areas in the translucent

Läseigen band be formed. Appropriately is at least one of the cylinders is designed as a drum motor. For the simultaneous display of several lines of characters, the tape wears according to FIG Improvement of several character sets in a row and behind the Band a corresponding number of lighting devices is arranged.

The innovation provides a very small display device that takes up little space and that also covers the plane Multiple lines can be displayed at the same time.

The innovation will now be explained with reference to the drawing. 1 shows a view and FIG. 2 shows a cross section through the display device according to the invention. The carrier tape 1 is driven by two cylinders 2, each of which is rotatable about its longitudinal axis 3. The band 1 bears k symbol symbols 5 * on lines parallel to the direction of rotation and lying next to each other.

[ arranges. The tape 1 can be, for example, a film strip,

j one edge of which is perforated. The Per-

foration of this strip can advantageously be used as possible Slip-free movement of the belt can be used. The belt is driven by at least one of the cylinders 2. For this purpose, it is useful to design one of the cylinders as a drum motor.

The display panel 6 of the device is delimited by panels 9. The display field can be so large that just a line of characters is visible. However, Bs can also reveal several parallel lines at the same time. In the latter case are on the Volume 1 provided several sets of character symbols one behind the other.

The symbol symbols 5 are illuminated in the display panel 6 by a lighting device 7 which is arranged behind the tape

is. The lighting device is movement-synchronous, for example mediated code tracks located on the tape, which are scanned opto-electronically, controllable. The lighting device 7 has for each character space to be displayed a light emitter, e.g. B. a light diode 8 on. Each light diode is controlled in such a way that it always lights up when the desired character appears at the character position in the display window. Shall characters on multiple lines at the same time are displayed, several such lighting devices are required. If the rotation is fast enough, the viewer will see a flicker-free line of characters.
