Abstract:
A device for truing a neck of a stringed instrument, comprising:a first bar-shaped member arranged and constructed to extend along a longitudinal direction of the neck; a second bar-shaped member arranged and constructed to extend substantially parallel with the first bar-shaped member, wherein a first end portion of the second bar-shaped member is affixed to a first end portion of the first bar-shaped member; a pull/push mechanism mounted on a second end portion of the first bar-shaped member and being arranged and constructed to apply a tensile force and a pressing force to a second end portion of the second bar-shaped member; and a directing mechanism arranged and constructed to direct the first bar-shaped member in a first direction when a tensile force is applied to the second bar-shaped member by the pull/push mechanism and to direct the first bar-shaped member in a second direction when a pressing force is applied to the second bar-shaped member by the pull/push mechanism, the second direction being opposite to the first direction; wherein the pull/push mechanism includes: a first actuation mechanism; and a second actuation mechanism operationally connected with the first actuation mechanism so as to transmit an output of the first actuation mechanism to the second bar-shaped member, the first actuation mechanism having an actuation ratio that is different from an actuation ratio of the second actuation mechanism.
