ABSTRACT:
There is disclosed an arrangement which has a projection means (LEDs) for projecting a light, a display means (mirror, finder view field range and the like) for guiding the light projected by the projection means to a predetermined display portion to display an index in the display portion, a variable means (masks, motor, decentring axis and the like) for periodically changing a projecting direction of the light of the projection means, and a control means (mask position detection circuit, control circuit and the like) for determining a projection timing of the projection means in accordance with the projecting direction changed by the variable means to control a position of the index on the display portion. By controlling the projection timing of the projection means, the position of the index in the display portion is controlled. Thereby, without irregularly or complicatedly changing the projecting direction itself, the index can be variously displayed.
