Claims

[Claims for Utility Model Registration] In a printer in which a printing member moves in pressure contact with a platen via recording paper to perform printing, the platen is fixed to a recessed portion of a substantially U-shaped platen base; The platen base includes a loose fitting hole perpendicular to the printing surface, a platen guide base provided with a pivot hole perpendicular to the printing surface corresponding to the loose fitting hole provided in the platen base, and the platen base and the platen guide base. It is characterized in that it is supported so as to be freely displaceable at a predetermined angle with respect to the platen guide base by a convex portion formed along the moving direction of the printing member on at least one side and a shaft having a function of preventing the platen base from falling off. printer's platen mechanism.
