Claims

[Claims for Utility Model Registration] (1) In a paper feeding device that is attached to a printing device and separates stacked sheets of paper one by one and supplies them to the platen of the printing device, the stacked paper is accommodated and the A paper feed tray is inclined so that the paper can fall under its own weight, a separating claw engages with the leading edge of the stacked paper, and the separating claw is rotatably driven in a direction opposite to the falling direction of the paper to retreat the leading edge of the paper. A paper feeding device comprising: a paper feeding rotary member that separates from the separating claw and separates from the paper. (2) Utility Model Registration The paper feeding device according to claim 1, wherein the paper feeding rotating body is interlocked with the platen. (3) Utility Model Registration The paper feeding device according to claim 1, wherein the paper feeding tray has an arm bent rearward at a lower end side.
