Abstract
A flow display type indicator is provided which indicates the variation or the velocity of variation of the value of a physical quantity or a parameter in a readily identifiable form. The indicator includes a flow image forming unit to indicate the value of the predetermined physical quantity in a flow representation by enabling a flow representing image to be formed at one of a plurality of positions including first to n-th positions which are orderly disposed and offset from each other along a predetermined line. A flow image selector selects one from flow representing images at the first to the n-th positions in one of first and second directions depending on the polarity of an input signal at a speed in accordance with the magnitude of the input signal to allow the flow representing image forming unit to form a selected flow representing image.
