摘要： A sheet-feeding mechanism comprises feed rollers attached to a first driving shaft and spaced from each other by a predetermined distance, two of the feed rollers being end feed rollers located at both ends of the first driving shaft. A pair of end ball rollers are attached to a second driving shaft and located in correspondence to the end feed rollers. A double-structure bail roller is attached to the second driving shaft in correspondance to the feed rollers, except for the end feed rollers. The double-structure bail roller includes an inner core and an outer layer having a small friction coefficient. The iner core is elastically deformable in a direction in which the end feed rollers are pressed against the corresponding bail rollers.

摘要： A thermal printer includes a first thermal head, a first platen roller, first biasing means, a second thermal head, a second platen roller, and second biasing means. The first thermal head, the first platen roller, the first biasing means are in contact with a heat-sensitive layer of thermal recording paper. The second thermal head, the second platen roller, and the second biasing means are in contact with a heat-sensitive layer of the thermal recording paper. The second thermal head is arranged on the upstream side of the first thermal head in a paper feed direction. A paper feed speed of the first platen roller to the thermal recording paper is larger than a paper feed speed of the second platen roller. The first platen roller is in contact with the thermal recording paper while being more slippery compared with the second platen roller.
