送ローラのリリース装置。 A pinch roller is disposed so as to be movable toward and away from the drive roller, and the pinch roller is brought into pressure contact with the drive roller by a spring, and a release frame is disposed so as to be movable along the paper conveyance path, and the Positioning the pawls of the release frame in relation to the pinch rollers and moving the release frame to one side causes the pawls to engage the pinch rollers, thereby causing the pinch rollers to become attached to the springs. In a release device for a paper transport roller, which is configured to separate from the drive roller against force, a cam is disposed on the rotation axis of the drive roller, and a peak of the cam faces a movement area of the release frame. A release device for paper conveying rollers, characterized in that the release frame, which has been moved in one direction, is returned to its original position by the operation of the cam as the drive roller rotates.
