<P>PROBLEM TO BE SOLVED: To set and modify touch feeling by a key guide mechanism in a keyboard device such as an electronic keyboard musical instrument. <P>SOLUTION: The keyboard device is provided with a key guide part 1 corresponding to keys 10. The key guide part has sliding parts 1a on the upper part. The sliding parts 1a are arranged inside the keys 10. When pushing and separating the keys 10, inside faces 10a of the key 10 slide to the sliding parts 1a and the sliding parts 1a guide rotation of the key 10. The same sliding part as the sliding parts 1a rotatably provides an elliptical key guide around a shaft orthogonal to a rotating shaft of the key 10 and changes resistance to the key 10 in response to a rotation position. A rotary guide is rotatably provided around the shaft parallel to the rotating shaft of the key 10, and the resistance is changed by change of thickness of the guide corresponding to the rotation position. When a lubricant is provided, a contact area of the key 10 and the key guide part 1 is changed to change viscosity resistance by the lubricant. <P>COPYRIGHT: (C)2009,JPO&INPIT |
