<p>PURPOSE:To automatically adjust the position of a paper for a recording device frame by adjusting the paper feeding-out direction by a resisting roller on the basis of the detection information by a sensor for the sent-out paper so that the feeding-out direction is at right angles to the generating line of a photosensitive body drum. CONSTITUTION:A paper feeding unit 1 is joined with a recording device frame 8 in horizontally swingable manners by a supporting point screw 9, and a normal/reverse revolution motor 10 for adjustment which has a revolution shaft as screw is installed at the part separated from the joint position so that the direction of a screw shaft 10a coincides with the swing direction, and the screw shaft 10a is screwed with the erection part 8a of a recording device frame 8 so that the distance between the paper feeding unit 1 and the recording device frame 8a is adjustable. The normal/reverse revolution control of the motor 10 is carried out so that the feeding direction of a paper P is perpendicular to the generating line of a photosensitive drum 5 on the basis of the information of a sensor 11 for detecting the right and left edges in the width direction of the paper sent out by a resisting roller 4.</p> |
