    • A pneumatic display device, comprising a plate block embodying a plurality of superimposed transparent plates, each of these plates being provided with means defining a disc guide channel. Each disc guide channel has a first air channel followed by a supply section for a plurality of non-transparent display discs displaceably arranged in a row therein, a display section following such supply section, said display section being in the form of a trace line for symbolizing a character at the region of a display zone limited by a display window provided at a nontransparent cover plate of the plate block. At the end of the display section such merges into a second air channel. Upon blowing air into the first air channel of a preselected plate the display discs thereof are displaced out of the supply section thereof into the display section thereof and thereby become visible at the display zone in the form of a desired character and upon further blowing air into the second air channel these display discs are again forced back into the supply section of the relevant disc guide channel.
    • 一种气动显示装置,包括体现多个叠加的透明板的板块,这些板中的每一个设置有限定盘引导通道的装置。 每个盘引导通道具有第一空气通道,随后是可移动地排列成行的多个不透明显示盘的供应部分,跟随该供应部分的显示部分,所述显示部分为轨迹线的形式, 象征着由设置在板块的不透明盖板上的显示窗限制的显示区域的区域。 在显示部分的末端,这样合并成第二空气通道。 当将空气吹入预选板的第一空气通道时,其显示盘从其供应部分移出到其显示部分中,从而在显示区域以所需字符的形式变得可见,并且进一步将空气吹入 第二空气通道,这些显示盘再次被迫回到相关盘导向通道的供应部分。
