Abstract
An automatic paper feeding device for a printer is disclosed which cyclically operates to automatically feed one after another of cut sheets of paper contained in a storage to a platen of the printer. A paper feed roller shaft is operatively connected to the platen, which is rotated by a motor, via a clutch mechanism including a clutch spring which is controlled by a controlling cam to intermittently and cyclically connect the shaft to a clutch sleeve connected to be rotated by the platen. Thus, after a paper sheet has been discharged from the printer after completion of printing, another paper sheet is automatically fed and positioned relative to the platen.
