| 摘要 | In order to provide a printer capable of detecting a continuous paper sheet without causing a sensor provided in the downstream side of a thermal head from being hindered by an ink ribbon, the printer includes: a main body (20) defining a conveying passage of a continuous paper sheet (P); a print unit having a thermal head (40) provided in the main body (20) to print predetermined information on the continuous paper sheet (P) by using an ink ribbon, and a platen roller (41) provided to face the thermal head (40) by interposing the continuous paper sheet (P); and a sensor unit (45) installed in the main body (20) and provided with a sensor (48) for detecting the continuous paper sheet (P), the sensor unit (45) being configured to move between a first position where the sensor (48) detects the continuous paper sheet (P) in the downstream side of the thermal head (40) and a second position farther than the first position from the thermal head (40). | ||

| 主权项 | 1. A printer with an ink ribbon for printing on a print medium, the printer comprising: a main body defining a conveying passage of a print medium; a print unit comprising a print head provided in the main body and configured to print predetermined information on the print medium by using the ink ribbon, and a platen roller provided to face the print head by interposing the print medium; and a sensor unit installed in the main body and comprising a sensor configured to detect the print medium, the sensor unit being configured to move between a first position, where the sensor detects the print medium in a downstream side of the print head, and a second position farther than the first position from the print head, wherein the sensor unit is pivotable with respect to a point provided in one end of a width direction of the print head, the sensor unit in the first position is set to face the print head in the downstream side of the print head, and the sensor unit in the second position is set in a position pivoted upward with respect to the point from the first position. | ||
