    Abstract: Problem: To change volume by a user quickly and prevent that loud audio that the user does not intend occurs.
    Solution: In case that the controller 2 receives movement of a target 23 to a limit area over a normal area, it moves a knob 22 with moving speed of the target 23 that movement of which is received within the normal area. And, the controller 2 moves the knob 22 and lower limit of the limit area from the lower limit of the limit area to a target 23 that is a movement goal position of the knob 22 with the same predetermined speed as expansion speed of the limit area while it expands the normal area toward the limit area side with the predetermined speed.

    Abstract: Provided is a rotary knob rotational structure being less susceptible to the influence of variation in the dimensions of a rotary knob and reducing backlash of the rotary knob while providing a suitable magnitude of rotational resistance to the rotary knob. The rotary knob rotational structure includes an annular sheet 22 interposed between a device body and the rotary knob 14, an attachment member 24 configured to attach a fixed portion 22a of the annular sheet 22 to the device body with the fixed portion 22a being interposed between the attachment member 24 and the device body, and a body-side protrusion 26 contacting the annular sheet 22 on the outside of the fixed portion 22a in the radial direction of the annular sheet 22 to warp the annular sheet 22 toward the rotary knob 14. The rotary knob 14 contacts the annular sheet 22 on the outside of the body-side protrusion 26 in the radial direction of the annular sheet 22 such that warpage of the annular sheet 22 biases the rotary knob 14 in the direction away from the device body, and is configured to be, in the biased state, slidable on the annular sheet 22 such that the rotational resistance is provided to the rotary knob 14.
