記載のプリンタのインクリボンエンド検出装置。[Claims for Utility Model Registration] (1) A pair of ink ribbon supply reel and take-up reel are provided via a platen, and a head is pressed against the paper wound around the platen via the ink ribbon. In a printer that prints by thermal transfer while feeding the ink ribbon, a guide is provided on the supply side of the ink ribbon so as to be movable in a direction in which it comes into pressure contact with the ink ribbon and in a direction in which the ribbon is stretched by a ribbon winding force. An ink ribbon end detection device for a printer, comprising: a roller; and a detection means for detecting movement of the guide roller in the ribbon tensioning direction due to the ribbon winding force near the end in the ribbon winding direction. (2) a link means in which the detection means movably supports the guide roller and is movable in a direction in which the guide roller is pressed against the ink ribbon and in a direction in which the ribbon is stretched by winding force;
Claim (1) characterized in that it comprises a spring that urges the guide roller in the pressure contact direction via the link means, and a detector that detects displacement of the link means in the tension direction. printer's ink ribbon end detection device. (3) A pair of ink ribbon supply reel and take-up reel are provided via a platen, and the head is pressed against the paper wound around the platen via the ink ribbon, and the ink ribbon is fed together with the paper to perform thermal transfer. A printer that performs printing includes a guide roller disposed on an ink ribbon supply path in front of the supply reel, and a direction in which the guide roller is pressed against the ink ribbon and a direction in which the ribbon is stretched by a ribbon winding force. a link means movably supported in the ribbon winding direction, and a spring biasing the link means in a direction in which the guide roller comes into pressure contact with the ink ribbon; An ink ribbon end detection device for a printer, comprising: a detector for detecting displacement of the link means due to the movement of the guide roller in the ribbon tensioning direction due to the ribbon winding force at the end. . (4) A pair of ink ribbon supply reel and take-up reel are disposed in parallel via a platen, and the ink ribbon supplied from the supply reel to the take-up reel is attached to the paper wound around the platen. , in a printer that presses a head onto the paper via an ink ribbon and prints by thermal transfer while feeding the ink ribbon along with the paper, one end of the ink ribbon on both sides of the ink ribbon supply path on the supply reel side is in a direction that intersects the supply path. a lever rotatably supported; a guide roller rotatably supported by the one end of the lever and pressed against the ink ribbon on the supply path; Detection for detecting the rotational displacement of the lever due to the movement of a spring that biases the lever and the guide roller near the end of the ribbon winding direction due to the ribbon winding force in the ribbon tensioning direction. An ink ribbon end detection device for a printer, comprising: (5) The printer according to any one of claims (1), (2), (3), or (4), further comprising positioning means for regulating the position of the guide roller in the direction of pressure contact with the ink ribbon. Ink ribbon end detection device.
