    • A printer comprises a printing mechanism (9) composed of a platen (9b) and a printing head (9c) for printing on a recording medium (C, S) via an ink ribbon, a paper path (30, 33) for guiding the recording medium to and past said printing mechanism (9), the printing head (9c) and the platen (9b) being disposed facing each other on opposite sides of the paper path (30), an ink ribbon feeding device (9e, 9d) for transporting the ink ribbon between the printing head and the paper path (30), a medium transport mechanism (7, 91, 92) for transporting the recording medium (C, S) along the paper path (30, 33), a detecting device (6, 96) for detecting a predetermined position of said recording medium along the paper path (30, 33), and a controller (100) for controlling the ink ribbon feeding device (9e, 9d). The controller (100) causes the ink ribbon feeding device (9e, 9d) to transport the ink ribbon by a predetermined amount in response to an output signal from the detecting unit indicating that the recording medium is at the predetermined position.
    • 打印机包括由压板(9b)和打印头(9c)组成的打印机构(9),用于经由墨带在记录介质(C,S)上打印,用于引导 记录介质到达所述打印机构(9)并且经过所述打印机构(9),打印头(9c)和压板(9b)彼此面对地布置在纸通道(30)的相对侧上,色带供给装置(9e,9d) 用于在打印头和纸张通道(30)之间传送墨带,用于沿着纸张路径(30,33)传送记录介质(C,S)的介质传送机构(7,91,92) 用于检测所述记录介质沿所述纸路径(30,33)的预定位置的装置(6,96)和用于控制所述色带供给装置(9e,9d)的控制器(100)。 响应于来自检测单元的指示记录介质处于预定位置的输出信号,控制器(100)使得色带供给装置(9e,9d)将墨带输送预定量。

    • A printer of a ribbon cassette fixed type, to which a ribbon cassette is detachably mounted, has a main body and a cassette mounting portion provided on the main body. The mounting portion has a cassette loading plate for loading the cassette thereon. The cassette includes two spools in parallel winding an ink ribbon therebetween. The printer includes a feed reel disposed at the loading plate and adapted to engage with one of the spools for feeding the ribbon, and a take-up reel disposed at the loading plate and adapted to engage with the other of the spools for taking-up the ribbon. A carriage is mounted in the main body movably along a printing direction. A print head is disposed on the carriage, to which a portion of the ribbon is set, for printing by using the ribbon discharged from the cassette by a movement of the carriage in the printing direction. The printer further includes a moving device provided to the mounting portion for moving the loading plate to a loading position, in which the cassette is positioned in a vicinity of the carriage so as to set the portion of the ribbon to the head along with a loading motion of the cassette, and an operating position, in which the cassette is positioned away from the carriage so as not to disturb the movement of the carriage.
