For example, a scroll operation will be performed.

Next, when the operating portion 23a of the rotary knob 23 is pressed in the direction perpendicular to the axis G1 direction, the rotary shaft 19 is rotated.
Is pressed through the engaging members 21 and 22, and the rotating shaft 19
Tilts in the direction of the inclined line Y1 with the contact portion on the one end side with the connecting body 20 as a fulcrum. Then, the driving body 24 moves downward against the spring member 25 on the other end side of the rotating shaft 19 and presses the movable contact 6 with the protrusion 24b. As a result, the movable contact 6 reverses, and the pair of fixed contacts 4b conducts,
The switch 7 is turned on.

Next, when the pressing operation of the rotary knob 23 is released, the drive member 24 is pushed back to its original position by the spring member 25, and the rotary shaft 19 and the engaging members 21 and 21 are released.
2, and the rotary knob 23 is also returned to the original state. Then, when the pressing of the movable contact 6 by the protrusion 24b is released, the movable contact 6 self-returns to the original state, and the pair of fixed contacts 4b becomes non-conductive, and the switch 7 is turned off.
It becomes the F state. By such an operation, the switch 7 is operated, and by operating the switch 7, for example, the scrolled portion is determined.

In the above embodiment, the switch 7 is described as a push type switch, but a switch other than the push type switch may be used. Further, although the description has been given of the case where the spring member is used for returning the driving body, the spring member may be omitted and the driving body may be returned by the movable contact. Further, in the above embodiment, the rotary knob 23 and the rotary shaft 1
9 has been described as being integrally rotatable via the engaging members 21 and 22, but the rotary knob and the rotary shaft are formed of the same member (one member) by a method such as molding with synthetic resin. May be.
