Abstract: A printer includes a conveying unit for conveying a rewritable printing medium toward a discharging portion along a conveying path, and the rewritable printing medium is erasable and printable by applying heat energy to the rewritable printing medium. The printer further includes an erasing unit including a heating body for erasing print of the rewritable printing medium by pressing the heating body to be in pressure contact with the rewritable printing medium, a printing unit for printing the rewritable printing medium, a determination unit for determining whether an abnormality occurs in conveyance of the rewritable printing medium, and a control unit for controlling at least one of the erasing unit and the conveying unit for releasing the pressure contact of the heating body on the rewritable printing medium, if the determination unit determines that an abnormality occurs.

Abstract: A printer includes an upper unit which opens and closes about a fulcrum lying at a rear position of a lower unit, and a paper path which is opened by opening the upper unit. A sensor unit is attached to the lower unit and includes a lower sensor holder and an upper sensor holder which are disposed in opposition to each other via the paper path. The paper path can be opened by pivoting the upper sensor holder relative to the lower sensor holder. When the upper unit is closed, the upper sensor holder is also closed in accordance with a closing pivoting motion of the upper unit.

Abstract: A conveyance unit conveys an RFID holding medium along a guide path for guiding RFID holding media and an RFID reader-writer conducts radio communication to an RFID chip placed in a predetermined communication position in the guide path. A control unit stops an RFID holding medium in the communication position and controls the RFID reader-writer to try first communication to the RFID chip. If first communication fails, the control unit conveys the RFID holding medium to the downstream side or upstream side of the guide path and controls the RFID reader-writer again to try communication to the RFID chip.

Abstract: A thermal print head has a row of heating elements arranged in a printing position in which the heating elements row abuts against a platen via a paper guide path. The thermal print head is held so as to be displaceable in an adjusting direction substantially orthogonal to a rectilinear direction between the heating elements row and the platen. Positioning pins projecting from both sides of the thermal print head are fitted in positioning grooves so as to be movable in the adjusting direction The position of the positioning pins in the positioning grooves is displaced in the adjusting direction by displacement of movable pieces each adapted to project selectively from opposite sides of each of the positioning grooves, thereby making the position of the heating elements row adjustable in the adjusting direction.

Abstract: A cutter unit including a cutter for cutting long paper in a direction orthogonal to a paper feeding direction is disposed on one side of a printer body provided with a printing mechanism. A cover is attached to the printer body so as to cover an outer surface of the cutter unit. The cutter unit and the cover are independently pivotable.
