Structure for confirming the adjusted position of a drum pedal

摘要

A structure for confirming the adjusted position of a drum pedal, wherein the drum pedal includes a support for a beater rotary shaft, a beater on the rotary shaft and a pedal connected by a sprocket and chain to rotate the shaft. A cam fixed on the protruding end of the shaft is urged by a spring to a standard orientation for the cam and the shaft. The rotary orientation of the cam on the shaft determines the initial spacing of the beater from the drumhead and the initial position of the pedal plate. A display member disposed on the part of the shaft that protrudes beyond the cam has a display scale which matches a standard position indicator on the cam to indicate the angular extent to which the shaft is rotated from a standard or initial orientation and therefore the extent to which the beater is initially off the drumhead and the extent to which the pedal plate is off a standard orientation.
