Abstract:
A sheet feeding apparatus comprising:a feeding roller for separating and feeding a sheet; a conveying roller for conveying the sheet; a drive motor directly connected to said conveying roller and for rotating forwardly and reversely; drive intermittent means for selectively transmitting a driving force from said drive motor to said feeding roller; and drive switching means for rotating said feeding roller in a conveying direction regardless of a rotational direction of said drive motor, wherein said drive switching means uses a spring clutch as a one-way clutch for effecting a drive transmission when said drive motor rotates said conveying roller in the conveying direction as a forward rotation and uses a clutch of pendulum type as a one-way clutch for effecting the drive transmission when said drive motor rotates said conveying roller in a direction opposite to the conveying direction as a reverse rotation, and a number of gears used for the forward rotation is different from a number of gears used for the reverse rotation by one gear or an odd number of gears.
