Scanner and image forming apparatus having the same that reduces the tilting of a moving unit

摘要

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.

主权项

1. 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.
