ヨグ・シヤトルダイヤル。[Claims for Utility Model Registration] The first and second brush means rotate over the first and second pattern pairs on the printed circuit board, thereby rotating the first and second rotation axes. In the jog/shuttle dial that detects directions and angles thereof, a first pattern connects one of the first pattern pair and one of the second pattern pair, and a first pattern connects the other of the first pattern pair and the second pattern pair. a second pattern that connects the other of the two pattern pairs; a third pattern that detects which of the first and second brush means is moved; and the first and second brushes. A jog/shuttle dial comprising, among the means, short-circuit prevention means for preventing short-circuiting of the first or second pattern pair by the brush means that does not move.
