ABSTRACT:
A fluorescent indicator apparatus comprises a first fluorescent display section including a plurality of grids, and anode segments corrsponding to the respective grids. A first driving device serves to drive the grids and the anode segments of the first fluorescent display section in a time-division manner to allow the anode segments of the first fluorescent display section to emit light. A second fluorescent display section includes a grid and an anode segment. A second driving device connected to the first driving device serves to drive the grid and the anode segment of the second fluorescent display section in synchronism with at least one of time-divided parts of the time-division drive of the first fluorescent display section to allow the anode of the second fluorescent display section to emit light.
