What is claimed is:

1. A keyboard to which key tops having different sizes are attachable, the key board comprising:
a slide member that is attached to one of the key tops, slides in accordance with an operation of the one of the key tops, and presses a contact via an elastic member; and
supporters, each allowing the slide member to be inserted therein,
wherein, when a key top having a size corresponding to a total size of first of the supporters, which are arranged in K columns and L rows, wherein each of K and L is an integer of two or more, is attached to the keyboard, the slide member is inserted in one of the first of the supporters, and a non-slide member is inserted in another of the first of the supporters that is located diagonally to the one of the first of the supporters in which the slide member is inserted, the non-slide member being attached to the key top and never sliding in accordance with the operation of the key top.

2. The keyboard according to claim 1 , wherein
the slide member is restrained from moving in a first direction and is movable in a second direction perpendicular to the first direction with respect to the key top, and
the non-slide member is restrained from moving in the second direction and is movable in the first direction with respect to the key top.

3. The keyboard according to claim 1 , wherein
the supporters have an identical shape.

4. A key switch comprising:
a single key top;
supporters arranged in K columns and L rows, wherein each of K and L is an integer of two or more,
contacts, each being located under a corresponding one of the supporters;
a slide member that is inserted in one of the supporters, is attached to the single key top, slides in accordance with an operation of the single key top, and presses the corresponding contact; and
a non-slide member that is inserted in another of the supporters, which is located diagonally to the one of the supporters in which the slide member is inserted, and never slides in accordance with the operation of the single key top.

5. The key switch according to claim 4 , wherein
the slide member is restrained from moving in a first direction and is movable in a second direction perpendicular to the first direction with respect to the single key top, and
the non-slide member is restrained from moving in the second direction and is movable in the first direction with respect to the single key top.
