SIMPLEX AND DUPLEX PRINTER

摘要

A compact simplex and duplex printer which can be produced easily at a low cost. The simplex and duplex printer includes: a thermal head for performing printing on a substrate; a rolled substrate supply section for supplying a continuous substrate, which is to be printed on one side, to the thermal head; and a sheet-like substrate supply section, provided below the rolled substrate supply section, for sequentially supplying sheet-like substrates, which are to be printed on both sides, to the thermal head. A guide transport path for guiding a sheet-like substrate from the sheet-like substrate supply section to the thermal head is provided between the thermal head and the sheet-like substrate supply section. To the guide transport path is connected a reversing mechanism for reversing the sheet-like substrate which has been returned from the thermal head to the guide transport path. The reversing mechanism includes a rotatable housing shell.

1. A simplex and duplex printer comprising:
a printing section; a rolled substrate supply section configured to supply a continuous substrate, which is to be printed on one side, from a roll of the substrate to the printing section; a sheet-like substrate supply section, provided below the rolled substrate supply section, configured to store sheet-like substrates which are to be printed on both sides, and sequentially supplying the sheet-like substrates to the printing section; a guide transport path configured to guide a sheet-like substrate from the sheet-like substrate supply section to the printing section; and a reversing mechanism, connected to the guide transport path, configured to reverse the sheet-like substrate, which has been returned from the printing section to the guide transport path, so that the printing section-facing surface changes from one surface to the other surface, wherein the reversing mechanism includes a rotatable housing shell having a cylindrical inner peripheral surface, and a drive mechanism configured to rotate the housing shell, and wherein the sheet-like substrate is reversed by disposing it along the inner peripheral surface of the housing shell, and rotating the housing shell by means of the drive mechanism.
