Abstract
A tractor and a continuous paper feed mechanism using the same which can more accurately convey continuous paper in a forward or reverse paper conveying direction by compensating for an increase or decrease in the width (taper) of the continuous paper due to a change in temperature or humidity. The change in paper width is compensated for by either employing a tractor having a pin belt that can incline relative to the paper conveying direction or by employing a tractor that pivots in accordance with the change in paper width to incline the pin belt.
