<P>PROBLEM TO BE SOLVED: To perform highly accurate belt drive robustly stably even with respect to load fluctuations due to paper having large fluctuation, a cleaning blade, etc., and to control the deflection of a belt. <P>SOLUTION: A belt drive control device includes: a first control system including a first motor driving a belt mechanism, a first control part controlling the first motor according to a predetermined target speed or target position, and a first driver part driving the first motor according to output from the first control part; and a second control system including a second motor transmitting a drive force different from that of the first motor to the belt mechanism, a second control part controlling the second motor, and a second driver part driving the second motor, according to output from the second control part. The second control part is configured to include a belt drive compensation part controlling the second motor according to the predetermined target speed or target position in the driving direction of the belt by the second motor and a torque drive compensation part adjusting the steady torque of the second motor. <P>COPYRIGHT: (C)2010,JPO&INPIT |
