Abstract
An electronic dial apparatus includes a rotating operation member, a conductive member rotating with the rotating operation member, a conductive pattern having a plurality of conductive areas electrically insulated from one another, the conductive member being configured to slidably contact the conductive pattern as the rotating operation member rotates, and a mode setter that sets a plurality of modes in accordance with a set position of the rotating operation member. The mode setter sets one of the plurality of modes based on a combination of a plurality of signal levels that depend on a contact position between the conductive member and the conductive pattern. The mode setter sets at least one of the plurality of modes for two combinations of the plurality of signal levels different from all combinations of the plurality of signal levels corresponding to each set position of the rotating operation member.
