Abstract:
A sheet supply device comprising:a rotatable shaft;a sheet supply roller that is fixed to the rotatable shaft such that the sheet supply roller rotates along with the rotatable shaft, the sheet supply roller supplying a recording medium in a predetermined direction while rotating, the sheet supply roller having a cross-section formed of a large radius segmental portion and a small radius segmental portion; andat least one idle roller that is freely rotatably mounted around the rotatable shaft, the idle roller having an inner surface to contact the rotatable shaft and an outer surface to contact the recording medium, the idle roller having a distance between the inner surface and the outer surface;wherein at least one of the rotatable shaft and the inner surface of the idle roller is formed to facilitate wear on the inner surface of the idle roller in order to decrease the distance between the inner surface and the outer surface of the idle roller from a friction generated between the rotatable shaft and the inner surface of the idle roller.
