Abstract
An operation apparatus is responsive to a physical action for inputting a control parameter of a musical sound into an electronic musical instrument. The operation apparatus is provided with a plurality of movable members individually responsive to the physical action to undergo a reciprocal movement. A frame mounts the plurality of the movable members in aligned manner. A tension member having a length is supported at both ends thereof by the frame to extend along the movable members such that each movable member may come into contact with the tension member during the course of the reciprocal movement of each movable member. A detector is connected to the tension member for detecting a deflection of the tension member caused by the contact of the movable member, and generates a signal corresponding to the detected deflection as the control parameter. A support member is arranged on the frame for supporting the tension member such that the support member acts on the tension member to restrict the deflection thereof around the movable member which contacts the tension member, thereby avoiding the deflection from spreading along the length of the tension member.
