  • Speed controller or an instrument having a speed controller including detection means for linearly detecting the amount of rotation less than one full rotation of a rotating member
    Patent number: 5590236
    Abstract: A speed controller includes a drive source, an input device for inputting the driving speed information of the drive source, a driver for driving the drive source on the basis of the driving speed information input by the input device, a detector for linearly detecting the amount of movement of the drive source an output device for outputting movement amount information obtained by the detector, and a corrector for correcting the driving speed information by the use of the movement amount information obtained by the detector, the corrector imparting new driving speed information as the corrected value to the driver.
    Type: Grant
    Filed: January 10, 1994
    Date of Patent: December 31, 1996
    Assignee: Canon Denshi Kabushiki Kaisha
