Abstract

PURPOSE:To remove flickering in a displaying state by simultaneously making both displaying element in accordance with a focal distance and elements which are in front and in the rear of the said element among plural displaying elements in displaying states. CONSTITUTION:A microcomputer 21 transmits an encoding signal showing the focal distance in accordance with the set zooming state of a zoom operational ring 1 to a 1st memory so as to selectively light an LED. At the same time, the LEDs in front and in the rear of the said LED are lighted so as to display the set focal distance on a display unit 13. The encoding signal showing an irradiation angle state from a pattern 15 is inputted in a 2nd memory. The computer 21 compares the contents of the 1st and the 2nd memories and when they do not coincide, it makes a motor 11 nomrally rotate or invertedly rotate. And when they coincide each other, it stops the motor 11. Since the LED which shows the set focal distance and the LEDs in front and in the rear of the said LED are lighted in the display unit 13, the flickering does not appear and smooth display is executed even if the set zooming state finely alteres.
