And a sensor 14 disposed on a surface of the roller 11, disposed near an outer circumference of the roller 11, for measuring a rotation angle of the roller 11.
The roll operation means may perform a first function according to the measured rotation angle of the wheel 11 when the wheel 11 rotates around the rotation shaft 12. That is, by the measurement of the angle, the rotational position of the wheel 11 can be accurately determined. However, the present invention is not limited thereto, and the rotational position of the roller 11 may be determined by measuring the distance over which the sensor 14 rotates.
When the roller 11 moves in the first direction, the first lever 13 moves in the first direction along with the movement of the roller 11, so that the first contact 131 provided on the first lever 13 also moves in the first direction, and a second function is triggered. That is, the second function described herein may be a power supply function.
The second rod 17 may be fixedly connected with the rotating shaft 12 or may be rotatably connected with the rotating shaft. When the roller 11 moves in the first direction, the roller 11 drives the rotation shaft 12 while moving in the first direction, and the other end of the second pin 17 rotates.
