ABSTRACT:
A display device has a display having a scale plate and an indicator movable on the scale plate, an instruction unit for releasing an instruction signal for moving the indicator, and a drive unit for moving the indicator based on the instruction signal. The device also has a detector for detecting whether the indicator is in movement or not. When the detector detects that the indicator is in movement, the movement of the indicator by another new instruction signal, eventually released from the instruction unit, is inhibited. Such movement of the indicator by another new instruction signal is permitted only when the detector detects that the indicator is not in movement.
