とを特徴とするプリンタの紙送り装置。 In a paper feed device for a printer, the platen is rotated by transmitting the rotation of the drive shaft to the platen shaft, and a tractor that engages with the print paper is rotated to feed the print paper when using a push tractor or a pull tractor. An idle shaft is provided between the shaft and the drive shaft, an idle gear is provided on the idle shaft that meshes with the drive gear of the drive shaft to rotate the idle shaft, and the idle shaft and the platen shaft are provided with idle gears that mesh with each other and rotate the idle shaft. An idle speed change gear train and a platen speed change gear train are provided which transmit the rotation of the shaft to the platen shaft and are relatively moved to change the speed of the platen shaft, and the speed of the idle speed change gear train and the platen speed change gear train is increased when the push tractor is operated. What is claimed is: 1. A paper feeding device for a printer, characterized in that a moving mechanism is provided that can move the paper relatively to the side and move the paper relatively to the deceleration side when a pull tractor is used.
