That is, the pattern pattern may be formed such that the arc length of the pattern formed on the inner side and the arc length of the pattern formed on the outer side are different from each other.

For example, the arc pattern may have a shorter arc length from the center point toward the outer circumferential direction. In other words, the pattern pattern can be realized with a shorter outer arc length than an inner arc length. However, in contrast, the pattern pattern may be formed such that the arc length gradually increases from the center point toward the outer circumferential direction. That is, the pattern pattern may have a longer arc length than an inner arc length.

The plurality of arc shapes forming the pattern pattern may have different distances from the center point in the outer circumferential direction.

Here, the spacing of the plurality of arc shapes may vary according to arc lengths formed in the outer circumferential direction from the center point.

For example, as shown in the figure, the arc pattern can be realized in such a manner that the arc length gradually becomes shorter from the center point toward the outer circumferential direction. In this case, as the number of the plurality of arcs increases toward the outer circumferential direction, the interval of the arc shape can be narrowed.

On the other hand, the arc pattern length can be gradually increased from the center point toward the outer circumferential direction. In this case, as the number of the plurality of calls decreases in the outer circumferential direction, the interval of the call type can be widened.
