装置。A platen knob in which a ratchet wheel integrally provided with a ratchet gear connected to a drive mechanism of a typewriter body is slidably and rotatably provided on a platen shaft connected to a platen, and the ratchet wheel is fixed to the platen shaft. In the platen barrier pull device, the serrations are engaged by the biasing force of a spring, and the ratchet wheel is slid on the platen shaft by operating a button to release the serration engagement. A central recess opening is provided on the side end surface opposite to the platen/branch 16 of the provided ratchet gear 36 and ratchet wheel 28, and a metal cylindrical body 38 is provided that tightly fits into the central recess.
A bearing 44 is mounted on the platen shaft 26, the inner circumferential surface of which is in close sliding contact with the platen shaft 26, and which receives the inner circumferential surface position near the open end of the cylinder 38 on the side opposite to the platen knob 20 when the ratchet wheel 28 engages with the platen knob 20 through serrations. A platen barrier pull device for a typewriter, characterized in that a spring is inserted between the bearing 44 and the inner wall of the central recess.
