发明名称 Gasoline pump modification apparatus
摘要 An apparatus for modification of a gasoline pump is disclosed. This apparatus incorporates electronically driven display numerals. The numerals are supported on a PC board recessed within a housing. They are slanted at an angle approximating 45 DEG . They are recessed into the housing and are surrounded by a nonreflective flat back housing incorporating an overhanging eyebrow and right and left shields. The recess further includes a generally horizontal flat cheek plate extending from the face of the panel back to the numeral display. The numeral is so arranged that it can be viewed from a substantial distance without ambiguities or distractions as a result of glare, and is otherwise highly visible. A circuit for driving the electronic numerical display is incorporated.
