<p>PROBLEM TO BE SOLVED: To provide the dial operation system information setting device of a camera constituted so that it is not affected by the changing point of a pattern, the possibility of a malfunction caused by chattering is eliminated and analogous operation feeling can be obtained. SOLUTION: A data setting device is constituted so that it can be bidirectionally rotated and set data is increased and decreased according to the rotating direction. In such a case, a first and a second different voltages are supplied to two concentrically arranged circular resistors 3 and 4. Besides, two brushes 5 and 6 slid on the resistors 3 and 4 by interlocking with each other are arranged so that voltage signals (signals 1 and 2) whose phase difference is 90 deg. are obtained from the brushes 5 and 6.</p> |
