Carrying apparatus, image forming apparatus, carried medium carrying method, computer readable medium storing computer program thereof

A carrying method of carrying a sheet-like carried medium comprising:

• carrying a sheet-like carried medium with a first rotating unit in a rotating direction;
• carrying the sheet-like carried medium with a second rotating unit arranged in an upper or lower stream side of the first rotating unit in the rotating direction;
• rotating the first rotating unit;
• rotating the second rotating unit;
• detecting a first rotational speed of the first rotating unit;
• detecting a second rotational speed of the second rotating unit;
• controlling the first rotational speed to be a first target speed;
• controlling the second rotational speed to be a second target speed;
• and
• acquiring torque information acting on the first rotating unit,
• wherein the controlling of the second rotational speed of the second driving unit rotating the second rotating unit is carried out in response to a comparison result between the torque information of the torque acting on the first rotating unit acquired when the sheet-like carried medium is solely carried by the first rotating unit and the torque information of the torque acting on the first rotating unit acquired when the sheet-like carried medium is carried by the first rotating unit and the second rotating unit.

A non-transitory computer readable medium storing a computer program containing instructions executable by a processor to perform carrying of a sheet-like carried medium comprising:

• carrying a sheet-like carried medium with a first rotating unit in a rotating direction;
• carrying the sheet-like carried medium with a second rotating unit arranged in an upper or lower stream side of the first rotating unit in the rotating direction;
• rotating the first rotating unit;
• rotating the second rotating unit;
• detecting a first rotational speed of the first rotating unit;
• detecting a second rotational speed of the second rotating unit;
• controlling the first rotational speed to be a first target speed;
• controlling the second rotational speed to be a second target speed;
• and
• acquiring torque information acting on the first rotating unit,
• wherein the controlling of the second rotational speed of the second driving unit rotating the second rotating unit is carried out in response to a comparison result between the torque information of the torque acting on the first rotating unit acquired when the sheet-like carried medium is solely carried by the first rotating unit and the torque information of the torque acting on the first rotating unit acquired when the sheet-like carried medium is carried by the first rotating unit and the second rotating unit.
