Abstract: There is provided 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 reversing mechanism for reversing a sheet-like substrate which has been returned from the thermal head is disposed between the thermal head and the sheet-like substrate supply section. The reversing mechanism is disposed just below the rolled substrate supply section.

Abstract: A paper roll feed mechanism rotates a paper roll including recording paper wound in a cylindrical shape to unwind the paper. The paper roll feed mechanism includes the following components. A supporting mechanism rotatably supports the paper roll. At least one paper feed roller unwinds the paper, serving as the outer surface of the paper roll supported by the supporting mechanism, in the lengthwise direction of the paper. A skew correcting member presses a side surface of the paper roll, supported by the supporting mechanism, in the widthwise direction of the paper. The skew correcting member presses outer part of the side surface of the paper roll in a paper unwinding region.

Abstract: A printing positioning mechanism includes a support shaft, a platen supported by the support shaft, and a printing head disposed in an opposing relationship to the platen for movement toward and away from the platen, and adjusts the positional relationship between the printing head and the platen when the printing head is moved toward the plate. The support shaft is movable in a plane perpendicular to an axial direction thereof, and the print head includes an aligning member interlinked with the print head for contacting with an outer periphery of the support shaft when the print head is moved toward the platen. The support shaft is moved to a predetermined position by contacting the aligning member with the outer periphery of the support shaft.

The drive transmission unit changes the selection of the clutch disks to which the driving force from the driver is to be transmitted so as to change the rotary torque of the rotational member.
