<p>PURPOSE:To reverse the front and the back surface of a display plate in one action and to improve operability by reversibly providing the display plate, detaching it from a dial main body through a compression coil spring and returning it after it is reversed. CONSTITUTION:The information of a first exposure mode (shutter prioirty AE) is displayed on the display surface 42 of the display plate 40 and the information of a second exposure mode (aperture-priority AE) is displayed on the display surface 41 thereof. When a knob part 42 is rotated counterclockwise in the case that the display surface is changed, the engagement of a projecting part 32 and an L-shaped groove part 23 is released and the plate 40 is detached upward by the pressing force of the compression coil spring 130. Then, it is freely rotated around the shaft part 31 of a holder 30. Thus, the plate 40 is reversed to the second display surface 41 from the display surface 42. By reversely executing the above described operation after the plate 40 is reversed, the plate 40 is mounted and fixed under a state which is set on the display surface 41.</p> |
