However, it should be understood that these practical details are not for limiting the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. Also, for the purpose of simplifying the drawings, a certain conventional structure and elements are shown simply and schematically in the drawings, and repeated elements may be denoted by the same numbers.

[0017] Also, in this specification, when an element (or unit or module, etc.) is "connected to" another element, it may refer to the case where the element is directly connected to the other element, or it may refer to the case where the element is indirectly connected to the other element. That is, there is still another element between the element and the other element. Only when it is explicitly stated that an element is "directly connected to" another element, it means that there is no other element intervening between the element and the other element. Note that terms such as first, second, third, etc. are merely for describing different elements and do not limit the elements themselves, so the first element may be renamed as the second element. Also, the combination of elements / units / circuits in this specification is not a generally well-known, conventional or well-known combination in the art, and it is impossible to determine whether the combination relationship can be easily completed by those skilled in the art depending on whether the elements / units / circuits themselves are well-known.
