る紙送り機構。 In a paper feed mechanism such as a facsimile machine, pulleys or gears of different diameters are attached to the paper conveyance roller shaft via one-way clutches each having a different locking direction, and one of the pulleys or gears is directly driven by the rotation of a drive motor. The other pulley or gear is rotated through means for reversing the rotational direction in the middle, and the rotational direction of the drive motor is changed between forward and reverse directions, thereby rotating the paper conveyance roller in the same direction, and , a paper feeding mechanism characterized by being able to change its rotational speed.
