Abstract
A paper tray of printer is provided, which includes a paper tray body, a slide shaft, a first pick arm, a second pick arm and a paper width guide. The first pick arm is fixed on the slide shaft, and the second pick arm is slidely disposed on the slide shaft. The paper width guide is disposed on the paper tray body and is connected to the second pick arm through a linkage device to drive the second pick arm, so that a position of the second pick arm varies along with a position of the paper width guide. Accordingly, an interval between the first pick arm and the second pick arm can be varied along with a size of a paper, so as to avoid paper skew when the paper is fed.
