<p><P>PROBLEM TO BE SOLVED: To make a finger not likely to jump out a key top of a keyboard for musical instrument such as a piano, an organ, and others in a keying method of pushing the finger out forward even when the keyboard has a small surface. <P>SOLUTION: The key top has a dam for locking a finger at its top-surface inner edge. The top surface of the key top is preferably slanted downward from the front side to the inner side and then raised slightly from the bottom part to form the dam. When a conventional keyboard for musical instrument uses key tops which each have a plane top surface and a small surface and is played by pressing a key down while pushing a finger out forward, the finger which is pressed down is likely to jump out of the key top, so powerful keying is impossible. Consequently, solved is the problem that a finger possibly jumps out of a key top in a keying method of pushing the finger out forward even when the key top has a small surface. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
