Flat optical display panel and keyboard for monetary conversion, for use in public places, frontier crossings, stations, air and sea ports, panel can display different sets of conversion data by altering the viewing angle of the panel

摘要

The optical panel is connected to a base part so that it can be inclined from a first position giving a first viewing angle to a second position giving a second viewing angle. The panel can be fitted to the base by a flexible U shaped part, a hinge, a pivot, or other suitable means. In each of the two positions of the panel different sets of relative monetary values are displayed. In a point of sale application a money collector (9) is included. The monetary converter has a movable support (91), on which is fitted an optical display (90). The support forms an inclined plane with small displacement angle just sufficient to ensure optical switching between a first set of monetary values and a second set of values relative to the first. Passage from one inclined state to the other is caused by the fall of coins into the collector. The unit is fitted with conversion calculator (96) conversion selector buttons and liquid crystal displays (94,95). Inclination of the optical panel can be done by pressing selection buttons (F,E)
