Abstract
An equipment is disclosed for displaying alphanumerical and/or pictorial information offering a high working reliability even in case of unfavorable working conditions. The plate of a display board is provided with a ground-color painted surface wherein one or more apertures are shaped along one or parallelly running more axes. Tiltable masks are arranged behind the aperture/s/ along at least one row in a manner that they may by tilting them be turned through the said aperture/s/ so as to cover each one dot of the surface of the said plate. The color of the masks is differing from the ground-color. The display pattern selection is performed by a mechanism comprising two levers arranged in different heights and angle positions at the body of the mask and co-operating with a fixed buffer and another buffer which can be changed over between two working positions the said buffers being arranged on a carriage displaceable along the plate.
