Abstract
Disclosed are a scanner and an image forming apparatus including the same. The scanner may include a scanning unit; a support unit configured to support the scanning unit; a first pinion rotatably disposed on the support unit and configured to move along a first rack of a first surface of a guide member; and a second pinion rotatably disposed on the support unit and configured to move along a second rack of a second surface of the guide member such that the direction of rotation of the second pinion is opposite to the direction of rotation of the first pinion, the second surface of the guide member being different from the first surface of the guide member.
Claims8
A scanner, comprising:
- a scanning unit;
- a movable unit, on which the scanning unit is mounted, including a first pinion, and a tilt prevention unit to limit an amount of tilting of a moving object in the scanning unit;
- the first pinion rotatably disposed on the movable unit and configured to move along a first rack of a first surface of a stationary guide member;
- the tilt prevention unit including a second pinion rotatably disposed on the movable unit and configured to move along a second rack of a second surface of the stationary guide member such that a direction of rotation of the second pinion is opposite to a direction of rotation of the first pinion, the second surface of the guide member being different from the first surface of the guide member;
- and
- an idle gear capable of transferring a rotation force from the first pinion to the second pinion.
An image forming apparatus, comprising:
- a scanner having a scanning unit, a guide member, a movable unit including a first pinion, and a tilt prevention unit to limit an amount of tilting of a moving object in the scanning unit, the tilt prevention unit including a second pinion, the guide member including a first surface having a first rack and a second surface having a second rack, the first surface of the guide member being different from the second surface of the guide member, the movable unit configured to support the scanning unit, the first pinion being rotatably disposed on the support unit and configured to move along the first rack of the first surface of the guide member, and the second pinion rotatably disposed on the support unit and configured to move along the second rack of the second surface of the guide member, a rotation direction of the second pinion being opposite to a rotation direction of the first pinion, and an idle gear capable of transferring a rotation force from the first pinion to the second pinion;
- and
- an image forming unit configured to reproduce an image scanned by the scanning unit on a printing medium.
A scanning unit, comprising:
- a first pinion configured to move with the scanning unit along a first rack of a first surface of a stationary guide member;
- a tilt prevention unit to limit an amount of tilting of a moving object in the scanning unit and including a second pinion configured to move with the scanning unit along a second surface of the stationary guide member such that a direction of rotation of the second pinion is opposite to a direction of rotation of the first pinion;
- and
- an idle gear capable of transferring a rotation force from the first pinion to the second pinion.
