Display Device for Messages Received by a Strip Printer

This system is for the display of messages received by a strip printer. For this purpose, the paper strip is replaced either by a transparent strip on which the message is printed in black or by a black one on which the message is printed with transparent matter.

The display device has an optical assembly allowing the image of a portion of the strip to be projected by focalization upon several lines of the screen, e. g., three.

The portion of the strip to be projected is located between rollers R1 and R2. The strip is subdivided into three parts 1, 2 and 3. Each is projected on one line of the screen in 1', 2' and 3', respectively. Three identical optical assemblies are each used for projecting one of the parts 1, 2 or 3.

Strip reading can be effected either at a standstill or on-the-fly. The direction of strip feeding is indicated by the arrow ------>. The characters on screen E then
flow from right to left on each line. They appear on the extreme right of line 3' on the screen and permanently disappear at the extreme left of line 1', following the path of the dotted arrows.

An optical device, e.g., the one projecting part 1 on line 1', is made up of a tubular lamp L1, a lens omega 1, two mirrors M1a and M1a' to form the image of 1 on screen E. Screens e eliminate possible projection beam interference. The beam corresponding to part 1 is shown diagrammatically from strip through lens omega 1, together with t...
