发明名称 OPERATION ELEMENT DEVICE OF ELECTRONIC MUSICAL INSTRUMENT
摘要 PURPOSE:To enable a player to immediately recognize that an operation element moves to an area with a different pitch variation curve by making a 2nd coil spring operates in addition to a 1st coil spring when rotation exceeds a specific quantity of rotation. CONSTITUTION:As the operation element 1 is rotated, a rotary member 1b moves one end 5a of the 1st torsion coil spring 5 against the energizing force of the 1st coil spring 5 and the player feels the resistance of the rotation of the operation element 1 from the energizing force. When the operation element 1 is further rotated, the rotary member 1b moves one end 7a of the 2nd torsional coil spring 7 in addition to one end 5a of the 1st torsion coil spring 5. The player recognizes that the rotation of the operation element 1 moves to the area with the different pitch variation curve from the increase in the energizing force. Further, an angle sensor is provided and the angle of the rotation is detected to output the pitch of the pitch variation curve.
