Claims

[Scope of utility model registration request]

A fluorescent display tube is used in which two or three different patterns of characters, symbols, etc. formed by predetermined fonts can be displayed on the same fluorescent display surface in a switchable manner. A display device that displays two or three types of patterns that are subject to switching display on the same fluorescent display surface, and which emits light in common regardless of which of the patterns is displayed. a first segment group formed by commonly connecting segments corresponding to the part; and a first segment group formed by commonly connecting segments corresponding to the part that is commonly emitted when switching between two types of patterns. a second group of segments;
A third segment group formed by commonly connecting segments corresponding to portions that are emitted only when displaying one specific type of pattern, and the supply state of operating voltage to each segment group. A character display device using a fluorescent display tube, which is equipped with a switching means for switching the above-described switching means, and is capable of selectively displaying each type of pattern on a fluorescent display surface by switching the switching means.
