ABSTRACT:
Knob-type operator provided on an operation section is provided with a switch mechanism that switches between ON and OFF states in response to depressing operation of the operator along the rotation axis of the operator. Operator operation detection circuit outputs, to a CPU, a rotated amount and direction corresponding to rotating operation of the operator. The rotated amount corresponding to rotating operation of the operator is converted into a variation amount of a setting of a parameter to be controlled. Resolution with which to associate the rotated amount with the variation amount can be set to any one of two types of resolution, coarse resolution and fine resolution. The rotated amount is converted into the variation amount in accordance with the currently-set type of resolution, and the parameter setting is changed on the basis of the variation amount.
