Patent ID: 8308100

Claim:
A recording medium feeding device for feeding a recording medium, which is wound in the shape of a roll and is supported by a support shaft, by means of a feeding roller comprising: a motor for generating a driving force; a driving force transmission unit for rotating the support shaft by transmitting the driving force; and a rotation resistance switching unit which can switch a limitation state of giving the support shaft a rotation resistance and an open state of not giving the support shaft the rotation resistance, wherein the rotation resistance switching unit includes a torque limiter being rotatable around the rotation shaft, and enters the limitation state by being fixed and enters the open state by being opened a torque limiter fixing unit being connected with the driving force transmission unit, and fix the torque limiter by a rotation of the motor in a first direction and open the torque limiter by a rotation of the motor in a second direction opposite to the first direction, wherein the torque limiter fixing unit includes a holder being movable in a third direction parallel to a longitudinal direction of the rotation shaft and fixing the torque limiter by being changed in position in the third direction.
