おける一次給紙ローラの駆動装置。With the cassette set in the copying machine, a rotating shaft is positioned above the copy paper in the cassette, and the rotating shaft and a drive sprocket are interlocked and connected via a clutch to rotate the rotating shaft intermittently. Further, in a driving device for a primary paper feed roller in a copying machine configured to sequentially supply copy sheets in the cassette to a secondary paper feed roller by a primary paper feed roller attached to the rotating shaft,
A clutch boss fixed to the rotating shaft and a boss portion of the drive sprocket are positioned opposite to each other, a spring is externally fitted over the outer periphery of both, and a clutch sleeve is externally fitted around the outer periphery of the spring. The drive sprocket side end of the spring is fixed to the clutch sleeve, the other end is a free end, and a rotation preventer is provided which can engage the clutch sleeve and prevent rotation of the clutch sleeve. , and the winding direction of the spring is set so that the spring tightens the boss portion by rotation of the sprocket when the rotation prevention by the rotation prevention device is released, and the second paper feed roller is fixed to the rotation shaft. A driving device for a primary paper feed roller in a copying machine, characterized in that:
