Abstract

PURPOSE: To readily discriminate the rotating direction of rotation operations by using two optical detecting elements.
CONSTITUTION: First, second optical detecting elements 1, 2 are arrayed on one side of a shield plate 17 which is secured to a revolving shaft 16 such as tuning shaft or the like and are connected to an up-down counter 15 by way of first, second inversion transistors 3, 4, first, second monostable multivibrators 5, 6, first, second flip- flop circuits 13, 14, etc. Then, when the shield plate 17 rotates along with the revolving operation of the revolving shaft 16, the first, second optical detecting elements 1, 2 make ON-OFF actions by mutually having time differences and according to the revolving directions thereof, the up-down counter 15 up-counts or down-counts. Hence, the revolving direction of the revolving shaft 16 is readily discriminated.
