CONSTITUTION:When the 1st keyboard unit 10 and 2nd keyboard unit 20 are combined to form the natural key keyboard 100, those keyboard units 10 and 20 are positioned by positioning means 15 and 25. Those positioning means 15 and 25 are arranged at the intermediate parts except the end parts in the key array direction at the common fitting parts 103 and 203 of the keyboard units 10 and 20. Consequently, the assembling operation is facilitated and the nonuniformity between adjacent natural keys is eliminated to prevent the beauty from being spoiled.</p> |
