Abstract
PURPOSE: To obtain an inexpensive, simple-structured paper-feeding mechanism for a small-sized printer which is provided with a paper-feeding roller driven by a ratchet wheel and a paper feeding lever or the like, and a paper pressing roller pressing on the, paper-feeding roller through the medium of a recording paper, or the like.
CONSTITUTION: A printing paper 5 is fed by means of a paper-feeding roller 18 and a paper-pressing roller 21. The paper-pressing roller 21 presses the paper-feeding roller 18 through the medium of the printing paper 5 with the force of a release spring 8 attached to a release lever 7. A cam part 12d of a rotary mechanism 12 engages a drive part 23a of a paper-feeding lever 23 to reciprocate the paper-feeding lever 23 in a direction of an arrow mark. A claw part 23c of the paper-feeding lever 23 engages the ratchet wheel 24 pivotably attached to a shaft 18a of the paper- feeding roller 18 to carry the teeth of the ratchet wheel 24 by each full tooth. The ratchet wheel 24 engages a transmission ratchet wheel 25, secured to the shaft 18a of the paper-feeding roller 18, in a manner to be pressed by a spring 26, and transmits the rotation, transfered by the paper-feeding lever 23, to the paper-feeding roller 18.
