Abstract:
1. A drive mechanism of a lifting rail for a musical instrument which comprises: dampers each configured to come into contact with a sound generating member provided for a corresponding one of a plurality of keys for generating a sound of one of a plurality of pitches that are generated by the musical instrument, so as to suppress a vibration of the sound generating member; damper levers each connected to a corresponding one of the dampers directly or indirectly for moving the damper away from the sound generating member in accordance with depression of a corresponding one of the plurality of keys; and a lifting rail having a bar-like configuration and configured to operate all of the damper levers, such that each of the dampers is spaced apart from the sound generating member, the drive mechanism comprising: a connection member to be connected to one end of the lifting rail; and a movement-force giving mechanism configured to move the lifting rail via the connection member in accordance with a signal to be inputted thereto, wherein the lifting rail includes: a hollow portion which is open at the one end of the lifting rail; and a through-hole which is formed through an upright wall portion of the lifting rail which stands in a vertical direction and which is one of a plurality of wall portions of the lifting rail situated between the hollow portion and an exterior of the lifting rail, wherein the connection member includes: an insertion member in which an attachment hole is formed at a position corresponding to the through-hole and which is to be inserted in the hollow portion of the lifting rail; and a fixing member configured to be inserted into the through-hole and the attachment hole for connecting the lifting rail and the connection member, and wherein the connection member includes a contact portion configured to come into contact with the one end of the lifting rail when the insertion member is inserted in the hollow portion by a prescribed distance so as to prevent the insertion member from being further inserted in the hollow portion, thereby positioning the attachment hole relative to the through-hole.
