Abstract

PURPOSE: To improve the appearance by dividing a prescribed key area into a first keyboard unit consisting of every other white key from a key of the lowest pitch and a second keyboard unit consisting of white keys other than those of the first keyboard unit and arranging positioning means of first and second keyboard units. CONSTITUTION: White keys in the prescribed key area are divided into a first keyboard unit 9 consisting of every other key from the key of the lowest pitch and a second keyboard unit 11 consisting of keys other than those of the first keyboard unit 9. When these first and second keyboard units 9 and 11 are combined to form the prescribed key area, these units 9 and 11 are mutually positioned by positioning means 15 and 19. These positioning means 15 and 19 are arranged in the middle path other than end parts in the key array direction of a common attaching part 3 of keyboard units 9 and 11. Thus, they are arranged as a keyboard without making the error conspicuous, and the beauty of the appearance is improved.
