Paper pushing unit of piano score page turning system

Abstract

The invention belongs to the technical field of musical instruments and relates to a paper pushing unit of a piano score page turning system. The paper pushing unit of the piano score page turning system solves the problem that an existing score page turning device influences the tone quality of a piano. The piano score page turning system comprises a score frame comprising a base plate and a faceplate. The paper pushing unit comprises a paper pushing pedal and a paper pushing stay rope. The paper pushing pedal is arranged at the bottom of the piano. The lower end of the paper pushing stay rope is connected with the paper pushing pedal. The upper end of the paper pushing stay rope is connected with a swing rod. The upper end of the swing rod is hinged to the face plate, and a resetting mechanism is arranged between the swing rod and the face plate. The lower end of the swing rod can swing to the position above the score on the face plate. When the paper pushing unit of the piano scorepage turning system is used for turning the score page, the influence on the tone quality of the piano is little.

Description

technical field [0001] The invention belongs to the technical field of musical instruments, and relates to a paper pushing unit in a piano music turning system.
