Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To reduce starting time drivingly connecting the rotating shaft of a first motor driving an object-to-be-driven and the rotating shaft of a second motor which has a driving torque larger than that of the first motor at the time of starting the object-to-be driven, and releasing driving connection before the object-to-be-driven is rotated uniformly. SOLUTION: A rotary shaft 36 of a DC motor 34 of a first motor and a rotary shaft 37 of a pulse motor 35 of a second motor are connected at the time of starting. A polygon mirror 32 of an object to be driven is driven by the pulse motor 35 of the second motor which has a larger driving torque to increase rotational speed in a short time. The connection of both rotating shafts 36, 37 are released before they are uniformly rotated. The polygon mirror 32 of the object-to-be-driven is driven by the DC motor 34 of the first motor which has a smaller driving torque, and accelerated to a prescribed speed at a high speed. The starting time of the motor is reduced, thus it is possible to prevent the productivity of image formation from being lowered, and prevent generation of noise and electric noise.
