ABSTRACT:
An apparatus for displaying a direction for adjusting its height to its appropriate height includes a plurality of light sources, a light receiving portion, and a control unit. The light sources are arranged in the form of a matrix in a display portion of the apparatus and displays the direction as a moving shape by emitting light in turn. The light receiving portion receives an incident beam and outputs a signal corresponding to a height of the incident beam. The control unit controls the light emission of the light sources in accordance with the signal so as to move the shape downward or upward to indicate the appropriate height. The control unit controls the light emission of the light sources so that at least one light source of a group of the light sources is lighted after a predetermined time, shorter than a time during which a human eye can keep an afterimage, after other members of the group were lighted.
