ABSTRACT:
A display apparatus in a camera for displaying photographic information using rotating elements. The display apparatus includes a rotating setting dial to rotatively set photographic information, and a display unit including pointers and pointer scales to display the photographic information set by the rotating setting dial. The pointer rotates about a fixed pointer scale in order to indicate photographic information on the pointer scale as set by the rotating setting dial. The display apparatus further includes a detector to detect a direction of rotation of the rotating setting dial, a drive unit to rotate the pointer, and a control unit to control the drive unit to rotate the pointer in the same direction as the direction of the rotating setting dial detected by the detector. In addition, the display unit may include at least one pointer which is controlled by a stepping motor to rotate the pointer in only one direction, regardless of the direction of rotation of the rotating setting dial.
