US Patent 7145069 Motorized page turner

The motorized page turning device automatically turns the pages of a multiple-page musical composition silently and accurately. Each page of the musical composition is attached to a respective shuttle. Each shuttle is rotatably connected to a shaft and has two opposing notches at a bore passing through each shuttle. A drive pin passes normally through a main shaft portion of the shaft and individually mates with the notches of each shuttle. The main shaft is connected to a rotational drive motor which rotates the shaft and a respective shuttle approximately 180 degrees. A linear drive sleeve of the shaft is connected to a linear drive motor which axially advances the shaft and drive pin to the next shuttle.
