Abstract
Disclosed are a scanner and an image forming apparatus including the same. The scanner may include a scanner 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.
Claims11
An operating method of a scanner comprising a scanning unit, a movable unit on which the scanning unit is mounted and on which a first pinion and a second pinion are disposed, and a stationary guide member, the method comprising:
- moving the first pinion along a first rack of a first surface of the stationary guide member;
- and
- limiting an amount of a tilting of a moving object in the scanning unit,
- wherein the limiting comprises transferring a rotation force, which is generated when the first pinion moves, to the second pinion, and moving the second pinion along a second rack of a second surface of the stationary guide member, which is different from the first surface thereof, such that a direction of rotation of the second pinion is opposite to a direction of rotation of the first pinion.
An operating method of an image forming apparatus comprising a scanner having a scanning unit, a movable unit on which the scanning unit is supported and on which a first pinion and a second pinion are rotatably disposed, a stationary guide member, and an image forming unit configured to reproduce an image scanned by the scanning unit on a printing medium, the method comprising:
- moving the first pinion along a first rack of a first surface of the stationary guide member;
- and
- limiting an amount of a tilting of a moving object in the scanning unit,
- wherein the limiting comprises transferring a rotation force, which is generated when the first pinion moves, to the second pinion, and moving the second pinion along a second rack of a second surface of the stationary guide member, which is opposite to the first surface thereof, such that a direction of rotation of the second pinion is opposite to a direction of rotation of the first pinion.
A method for limiting an amount of a tilting of a moving object in a scanning unit, comprising:
- rotating a first pinion in a first direction to move with the scanning unit along a first rack of a first surface of a stationary guide member;
- transferring a rotation force, which is generated when the first pinion rotates, to a second pinion;
- and
- rotating the second pinion in a second direction opposite to the first direction to move with the scanning unit along the first rack of the first surface of the stationary guide member.
A method for limiting an amount of a tilting of an object moving in a unit, the method comprising:
- transferring a force, which is generated when a first gear moves along a first surface of a guide member on which the moving object is disposed, to a second gear;
- and
- moving the second gear along a second surface of the guide member such that a direction of a rotation of the second gear is opposite to a direction of a rotation of the first gear.
