Abstract
A page turning device for use with any bound pages such as books, music scores, or binders, which have small ferrous elements (14) attached to the edge of each page. The device uses a motorized arm (16) with a magnetic tab (17) mounted on the end to engage individual pages and turn them in either the forward or reverse direction. The magnetic tab (17) is raised during a page turn, but rests in a downward position between page turns so as to not interfere with manual manipulation of the pages. The device further incorporates foot actuated user switches (12,13) which control the mode of operation and cause the device to turn a page in the appropriate direction.
Claims20
A device for turning pages comprising:
- in combination, a first assembly having a first electro-motive device and first means for conveying rotational energy from said first electro-motive device to a final drive shaft, said assembly being mounted on a frame;
- an arm member mounted on one end to said final drive shaft, said arm member being rotationally moveable in a horizontal plane;
- a magnetic tab mounted pivotally on opposite end of said arm member, said tab being rotationally moveable in a vertical plane;
- in combination, a second assembly having a second electro-motive device and second means of converting rotational energy to linear energy from said second electro-motive device to said magnetic tab causing said magnetic tab to pivot;
- an electronic circuit that controls the operation of said electro-motive devices;
- and
- an electro-mechanical transducer connected to said electronic circuit adapted to communicate an user inputs to said electronic circuit.
A device for turning pages comprising:
- a first assembly having a first electro-motive device and first means for conveying rotational energy from said first electro-motive device to a final drive shaft, said assembly being mounted on a frame;
- an arm member mounted on one end to said final drive shaft, said arm member being rotationally moveable in a horizontal plane;
- a magnetic tab mounted pivotally on said arm member, distal to said shaft, said tab being rotationally moveable from a down position to an upright position in a vertical plane;
- a second assembly having a second electro-motive device and second means of converting rotational energy to linear energy from said second electro-motive device to said magnetic tab causing said magnetic tab to pivot;
- an electronic circuit that controls the operation of said electro-motive devices;
- and
- an electro-mechanical transducer connected to said electronic circuit adapted to communicates user inputs to said electronic circuit.
A device for turning pages comprising:
- a frame;
- a first electric motor mounted to said frame and operably engaged to a rotatable shaft;
- an arm mounted on said shaft between a first arm position and a second arm position at a proximal end for rotation through an arc by said shaft;
- a member pivotally mounted at a distal end of said arm and biased to reside in a first position generally parallel to said arm;
- a magnetic tab on said member;
- a second electric motor mounted to said frame;
- means to convert rotary motion to linear motion operably associated with said second motor;
- a transmission means linking said member to said means to convert rotary power in order to pivot said member to a second position, which is not parallel to said arm when said second motor is actuated;
- a controller for operating said motors;
- a forward switch operably connected to said controller for sequentially moving said arm and said tab for moving the page from a first position to a second position
- a reverse switch operably connected to said controller for sequentially moving said arm and said tab for moving the page from said second position to said first position and
- a power source for said electronics.
