Abstract
A vibration reduction gear structure of an image input and output device includes a first gear supporting a second gear, and a vibration reduction portion made of vibration reduction material mounted on at least one of the first gear and the second gear. The other gear is rested on the vibration reduction portion. In such a manner, when the first gear and the second gear are rotated synchronously, the vibration between the first gear and the second gear may be reduced by the vibration reduction portion.
