摘要： This invention consists of a rectangular board having a longitudinally disposed upturned lower edge to prevent the sheet of music or the like that is placed on the board from sliding off. Two diametrically opposed spring clips on the board hold the music in place. An electric motor is located on the upper right hand corner of the board, the motor being provided with a pulley that has an endless cord encompassing the same, the cord also encompasses a free-turning pulley that is located on the opposite side of the board. A wire track is suitably mounted parallel to the just-mentioned cord. The purpose of the wire track is to provide a means of guiding a swivel fastener which is connected to the cord and also to a spring clip, the spring clip being secured to the sheet of music or page that is to be turned. A foot-operated switch, that is connected to an electric motor, completes the construction of this invention which is preferably mounted on a vertically disposed stand.
