<P>PROBLEM TO BE SOLVED: To provide a bender device of an electronic musical instrument in which the thickness of the device is thinly formed by a simple constitution. <P>SOLUTION: Contacting sections 10d, which contact with pressed surfaces 11b formed on an elastic member 11, is formed on both ends of a key top 10. The elastic member 11 is a member which is formed by silicone rubber and has elasticity and the pressed surfaces 11b, that are respectively pressed by the contacting sections 10d formed on the both ends of the key top 10 along the longitudinal direction, are formed on the elastic member 11. A spherical section 11c, which has a spherical surface having projection toward bottom, is formed on the bottom section of the pressed surface 11b and the inside of the spherical section 11c is made hollow. In a normal condition, the tip of the spherical section 11c is contacted to a pressure sensitive sheet 12. When pressure force is applied to the pressed surface 11b, the spherical surface of the spherical section 11c is deformed into a flat surface in accordance with the pressure force being applied and the area which contacts with the pressure sensitive sheet 12 is increased. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
