Abstract
A method and apparatus for synchronizing the operation of multiple elements of a system to the motion of a movable element using a programmable element as the control element.
Claims13
A synchronization apparatus comprising;
- a movable element;
- an operating element;
- means for generating a first reference signal corresponding to an operational position of said movable element;
- means for generating a second reference signal corresponding to an operational characteristic of said operating element;
- and
- a programmable element, including a clock input for receiving said first reference signal and a data input for receiving said second reference signal, for producing a synchronization control signal in response to said first and second reference signals;
- and
- means, responsive to said synchronization control signal, for synchronizing the operational characteristic of said operating element with the operational position of said first movable element.

A synchronized motor assembly for a scanning system comprising:
- means for deflecting a scanning beam onto a supply of imaging media supported on a scanning support surface;
- a first motor for rotating said beam deflecting means to direct said scanning beam across said imaging media;
- a carriage for supporting said mirror;
- a second motor for displacing said carriage relative to said scanning support surface;
- encoder means for providing a first reference signal corresponding to an angular position of said first motor and for providing a second reference signal corresponding to an angular position of said second motor;
- a programmable element, including a clock input for receiving said first reference signal and a data input for receiving said second reference signal, for producing a synchronization control signal in response to said first and second reference signals;
- and
- means, responsive to said synchronization control signal, for controlling a rotational velocity of said second motor to provide synchronization between the angular position of said first motor and the angular position of said second motor.

A synchronized motor assembly for a scanning system comprising:
- means for deflecting a scanning beam onto a supply of imaging media;
- a first motor for rotating said beam deflecting means to direct said scanning beam across said imaging media, said scanning beam forming a scan line on said imaging media;
- a second motor for distributing a series of said scan lines across said imaging media;
- encoder means for providing a first reference signal corresponding to an angular position of said first motor and for providing a second reference signal corresponding to an angular position of said second motor;
- a programmable element, including a clock input for receiving said first reference signal and a data input for receiving said second reference signal, for producing a synchronization control signal in response to said first and second reference signals;
- and
- means, responsive to said synchronization control signal, for controlling a rotational velocity of said second motor to provide synchronization between the angular position of said first motor and the angular position of said second motor.
