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.
Claims17
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.
The scanner according to 12, further comprising:
- a driving gear coupled to the driving pulley in such a manner that the driving gear and the driving pulley are rotatable together, wherein the power transmitting unit further comprises:
- a first actuator coupled to the first swing gear so as to move the first gear selectively to a first position and a second position, the first swing gear being in engagement with the driving gear when the first swing gear is in the first position, the first swing gear being spaced apart from the driving gear when the first swing gear is in the second position;
- and a second actuator coupled to the second swing gear so as to move the second gear selectively to a third position and a fourth position, the second swing gear being in engagement with the driving gear when the second swing gear is in the third position, the second swing gear being spaced apart from the driving gear when the second swing gear is in the fourth position.
