    • A thermal printer accepting an ink ribbon cartridge (90) includes a chassis (3), a thermal head (16) secured to the chassis and a platen roller (21) which is rotatably supported in the chassis and swingably movable relative to the thermal head. The platen roller is rotated by a first platen driving (30) mechanism and is moved toward and away from the thermal head by a second platen driving mechanism. When the platen roller (21) is moved to contact the thermal head (16) via an ink ribbon (94) intervened therebetween, an image is printed on a printing medium (10) fed between the platen roller (21) and the ink ribbon. The printer accomplished aligned overprinting on the printing medium (10) via a paper supply mode, a printing mode, a paper retract mode and a paper discharge mode effected by the first and second platen driving mechanisms.
    • 接受墨带盒的热敏打印机包括底盘,固定在底盘上的热敏头,以及可旋转地支撑在底盘中并相对于热头可摆动地移动的压纸滚筒。 压纸辊由第一压板驱动机构旋转,并通过第二压板驱动机构朝向和远离热敏头移动。 当压纸辊移动以通过介于其之间的墨带接触热敏头时,图像被印刷在供给在压纸辊和墨带之间的打印介质上。 打印机通过由第一和第二压板驱动机构实现的供纸模式,打印模式,退纸模式和排纸模式,在打印介质上完成对齐叠印。
