Abstract
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.
Claims33
A page turning device comprising:
- a shaft having a rotatable main shaft and a linear drive sleeve;
- a drive pin having first and second ends passing normally through the main shaft;
- a plurality of shuttles rotatably connected between the main shaft and the linear drive sleeve, each shuttle having opposing first and second notches located at an interior circumference of the shuttle, the notches being sized to mate with the first and second ends of the drive pin;
- means for rotating the shaft;
- means for axially advancing the shaft;
- and
- means for controlling and sensing motion of the plurality of shuttles and the shaft.
A device for turning pages comprising:
- a shaft having a main shaft and a linear drive sleeve;
- a drive pin carried by the shaft;
- a plurality of shuttles, each shuttle having a bore sized to accept the shaft and engaging the drive pin, the plurality of shuttles being stacked between the main shaft and the linear drive sleeve and proximate to the drive pin;
- a rotational drive for rotating the shaft and one of the plurality of shuttles about 180 degrees;
- and
- a linear drive for axially advancing the shaft and drive pin to adjacent shuttles.
A portable page turning device comprising:
- a shaft having a main shaft and a linear drive sleeve;
- a drive pin having first and second ends and passing normally through the main shaft;
- a plurality of stacked shuttles rotatably connected to the shaft between the main shaft and the linear drive sleeve, each shuttle having opposing first and second notches located at an interior circumference of the shuttle sized to mate with the first and second ends of the drive pin;
- a rotational drive for rotating the shaft;
- a linear drive for axially advancing the shaft;
- and
- a logic circuit for controlling and sensing motion of the plurality of shuttles and the shaft.
A page turning device comprising:
- a shaft having a rotatable main shaft and a linear drive sleeve;
- a plurality of shuttles stacked between the main shaft and the linear drive sleeve;
- means for selectively engaging the shuttles;
- means for rotating the shaft;
- and
- means for axially advancing the shaft.
A page turning device comprising:
- a shaft having a rotatable main shaft, linear drive sleeve, and protrusion;
- a plurality of shuttles, each shuttle having a bore sized to accept the shaft and engaging the protrusion, the plurality of shuttles being stacked between the main shaft and the linear drive sleeve and proximate to the protrusion;
- a rotational drive for rotating the shaft and one of the plurality of shuttles;
- and
- a linear drive for axially advancing the protrusion to adjacent shuttles.
A method for turning pages, the method comprising:
- attaching a first page to a first shuttle rotatably connected to a shaft, the first shuttle comprising a first and a second notch;
- attaching a second page to a second shuttle rotatably connected to the shaft, the second shuttle comprising a first and a second notch;
- aligning a drive pin connected to the shaft with the notches of the first shuttle;
- rotating the shaft until the notches of the first and second shuttles are realigned;
- axially advancing the shaft until the drive pin is aligned with the first and second notches of the second shuttle;
- and
- rotating the shaft until the notches of the first and second shuttles are realigned.
A method for turning pages, the method comprising:
- attaching a first page to a first shuttle rotatably connected to a shaft;
- attaching a second page to a second shuttle rotatably connected to the shaft;
- aligning a protrusion of the shaft with the first shuttle;
- rotating the shaft approximately 180 degrees;
- axially advancing the shaft until the protrusion is aligned with the second shuttle;
- and
- rotating the shaft approximately 180 degrees.
