摘要： An indicator device for a camera for displaying the value of an item of information related to photographic conditions includes an indicator means, which includes a scale plate with a central point, a number of index marks being inscribed on the scale plate around the perimeter of a circle which has the central point as its center and the angular positions of the index marks relative to the central point being a subset of the angular positions derived by subdividing the circumference of the circle into sixty equal divisions, and an indicating pointer which is rotatable around the central point against the scale plate. The indicating pointer is rotationally driven against the scale plate by a drive means such as a stepper motor.Thereby, by intuitive analogy with the face of a clock, a user can perceive the value of the item of information from the angular position of the pointer relative to the index marks. Optionally several indicating pointers may be provided and may be driven by the drive means so as together to display the value of a single item of information related to photographic conditions by their angular positions relative to the index marks, considered together.
