Abstract
A scanner with a first driving motor and a second driving motor has an improved driving structure as transmission of a driving force from one of the first and the second driving motors to the other driving motor is inhibited, thereby preventing loss of power and increased noise and vibration. The scanner may include a first driving motor, a second driving motor, an operating unit operable to move the scanning unit and configured to operate by a driving force generated from one of the first and the second driving motors and a power transmitting unit configured to transmit the driving force generated from one of the first and the second driving motors to the operating unit while disallowing transmission of the driving force between the first and the second driving motors.
Claims20
An apparatus for driving a movement of an image scanner, comprising:
- a first motor configured to generate a first driving force;
- a second motor configured to generate a second driving force;
- an operating unit configured to receive a driving force and to be operably coupled to the image scanner so as to cause the movement of the image scanner in response to the received driving force;
- and
- a power transmitting unit configured to transmit the driving force to the operating unit while preventing transmission of the driving force between the first and second motors, the driving force being one of the first driving force received from the first motor and the second driving force received from second motor.
A scanner, comprising:
- a scanning unit configured to receive light from a document to be scanned;
- a scanning carrier supporting thereon the scanning unit;
- a driving belt connected to the scanning carrier;
- a driving pulley and a driven pulley each supporting the driving belt in such a manner that the driving belt is rotatable in response to a rotation of the driving pulley;
- first and second motors configured to generate a first and second driving forces, respectively;
- and
- a power transmitting unit configured to transmit a driving force to the driving pulley while preventing transmission of the driving force between the first and second motors, the driving force being one of the first driving force received from the first motor and the second driving force received from second motor.
An image scanner for reading an image of a document, comprising:
- a scanning unit configured to receive an optical information relating to the image of the document;
- a scanning carrier supporting the scanning unit;
- and
- first and second motors each configured to generate a driving force to move the scanning carrier,
- wherein transmission of the driving force between the first motor and the second motor during a movement of the scanning carrier is prevented.
