Abstract

A dispenser for a roll of paper, a deflectable paper guide and systems for indicating when a predetermined amount of paper is left on the roll and when the supply of paper is totally exhausted. The paper dispenser is mounted on a printer frame and includes first and second cylindrical rollers having large and small diameter sections which permit the roll of paper to be readily inserted in and removed from the dispenser assembly. The deflectable paper guide is positioned between the paper dispenser and a fixed paper guide and includes a bar oriented parallel to the longitudinal axis of the roll of paper and biaser which forms a loop in the paper guide. The low paper quantity indicating system includes an infra red transmitter and an infra red receiver which are positioned in axial alignment on opposite ends of the roll of paper. An indicating device indicates when a clear path is established between the transmitter and the receiver which is indicative of a predetermined amount of paper remaining on the roll. The paper out indicating system includes a groove which is formed in the printer device drive roller and an aperture in a fixed paper guide which is positioned adjacent to the drive roller. The aperture is aligned with the groove in the drive roller. A switch having a long, readily deflectable arm is positioned so that the arm can be deflected through the aperture.
