Abstract

PURPOSE: To attain minute setting over a wide range by applying N-th power to the rotating speed of a rotary dial (N>2) and adding/subtracting the result accumulatingly so as to obtain a change in response to the rotary speed of the rotary dial.
CONSTITUTION: The rotary dial 1, a rotary encoder 2 driven by the dial, a decoder 3 extracting a signal DR representing the direction of revolution of the rotary dial from the output of the rotary encoder, an up-down counter 4 counting the output Pa of the rotary encoder for a prescribed period and subject to up-count or down-count control by a signal DR representing the direction of rotation, an N-th power circuit 6 applying N-th power to teh count output of the up-down counter and an adder/subtrator circuit 7 adding or subtracting accumulatingly the output of the N-th power circuit according to the signal representing the direction of rotatoin are provided. Then the control output in response to the rotating speed of the rotary dial is obtained from the adder/subtractor circuit. Thus, the resolution is changed continuously steplessly in response to the dial rotating speed to improve the operability.
