Patent ID: 8000622

Claim:
A moving body controlling device comprising: a first moving body configured to be rotated by a first motor; a second moving body configured to affect movement of the first moving body; a second motor configured to rotate a second moving body; a surface speed detecting unit configured to detect a surface speed of the first moving body; a first control unit configured to control rotation of the first motor; a second control unit configured to control rotation of the second motor; a memory unit configured to store a relationship between the rotational speed of the second motor and an indicating value for driving at least one of the first motor and the second motor when the second control unit changes the rotational speed of the second motor while the first control unit controls a rotational speed of the first motor to cause the surface speed detected by the surface speed detecting unit to be a predetermined speed, when the moving body controlling device is in a mode of setting a target rotational speed of the second motor; a reference point detecting unit configured to detect based on the relationship stored in the memory unit a reference point of the rotational speed of the second motor, at which the surface speed of the first moving body starts to exceed the predetermined speed, when the moving body controlling device is in the mode of setting the target rotational speed of the second motor; and a setting unit configured to set the target rotational speed of the second motor based on the reference point detected by the reference point detecting unit, when the moving body controlling device is in the mode of setting the target rotational speed of the second motor, wherein when the moving body controlling device is not in the mode of setting the target rotational speed of the second motor, the first control unit controls the rotational speed of the first motor to cause the surface speed detected by the surface speed detecting unit to be the predetermined speed, and the second control unit controls the second motor to rotate at the target rotational speed.
