Abstract
A control unit for a moving body such as an optical system of a copying machine includes detection means for detecting a moving status of the moving body and control means for controlling the movement of the moving body in accordance with a detection output of the detection means. The control means contains data corresponding to the detection output to control the moving body in accordance with the detection output.
Claims12
A control unit for a moving body, comprising:
- a moving body;
- a motor for driving said moving body in response to drive data;
- means for detecting a velocity of said moving body and generating velocity data;
- means for detecting a position of said moving body and generating position data;
- and
- means for controlling said moving body in accordance with the velocity data from said velocity detection means and the position data from said position detection means,
- said control means including:
- first storage means for storing preset target velocity data for controlling said moving body in accordance with the position data from said position detection means;
- second storage means for storing preset drive data for driving said motor in accordance with the position data from said position detection means independently of said target velocity data;
- means for comparing the velocity data from said velocity detection means and the target velocity data;
- and
- means for outputting correction data for correcting the drive data in accordance with an output from said comparing means.
