Abstract
A sheet conveyor includes a first conveyance belt, a second conveyance belt, a first driving roller, a second driving roller, a first gear, and a second gear. In switching between sandwich and separation states, an axial center of a rotation shaft of the first or second gear moves on a movement plane substantially perpendicular to a direction in which the first conveyance belt and the second conveyance belt convey a sheet. Where L represents diameter of a tooth edge circle of the second gear in unit of millimeter and Trepresents a chordal tooth thickness of the second gear, an acute-side angle θ in unit of degree (°) formed by the movement plane and an interaxial-center plane including the axial center of the rotation shaft of each of the first gear and the second gear in the sandwich state is within a range represented by the following Formula 1: Tan(2×T/L)<|θ|<45°.
