Whether it is a parallel movement operation may be recognized as whether a detection signal is input from the movement detector 115. As illustrated in FIG. 10, in the case of a parallel movement operation, the length of the elastic band 250 (or the elongation of the elastic band 250 is 0, there is no change in length, but the elastic band 250 is pulled by the trigger 860. The length of the entire perimeter formed by the tact switch 260 will begin to increase. If it is determined that the operation is a parallel movement, the controller 130 proceeds to step 930 and controls the operation of the sensing unit 120 to detect a sensing signal input from the sensing unit 120. For example, the sensors of the sensing unit 120 may be switched to a power-on state by the operation start control of the controller 130.

It is determined whether the parallel movement is terminated in contact with the start contact part 810 again in the state of not contacting with the contact point). In addition, if the slider 230 is moved in parallel to the maximum distance (ie, parallel movement in the north-west, north-west direction, or parallel movement in the diagonal direction), the movable contact portion 830 of the tact switch 260 is connected to the end contact portion 820. Since the operation of the signal counter will be terminated by the contact, the controller 130 may refer to this.

- the above-described cases are methods for processing irrespective of the input order of the vertical input signal and the sensor signal, but may also consider the input order of the vertical input signal and the sensor signal. For example, when a vertical input signal is input first and then a sensor signal is input (that is, parallel movement is completed), a, b, c or d may be set to be input according to the moving direction of each slider 230, and the sensor signal may be input. When the first input signal is input and the vertical input signal is input, p, q, r or s may be set according to the moving direction of each slider 230.
