Abstract

PURPOSE: To improve the reliability of printing function and make paper mounting easy by constituting the paper feed mechanism through the use of the friction roller device consisting of a pair of tractors and one set of adsorption system.
CONSTITUTION: Paper is conveyed by providing a pair of tractors 2 having the function of sending out paper 1 by providing protruding pawls to, e.g., conveying belts on the side before printing than the slide contact point of the paper and photosensitive drum 3 and one set of friction roller device 5 on the side after printing. This roller device 5 is constituted by a roller 6 which makes slide contact with the paper 1 and carries out the same forward owing to frinction force, a case 7 which is so provided as to cover this roller and has the opening 7a only at the place where the roller and paper make sliding contact, a vacuum pump 8 which reduces the pressure of the inside of this case and a guide cover 9 which guides the paper 1. This makes mounting of the paper easy and enables reliable printing to be accomplished.
