Dot line printer with paper slack elimination mechanism |
摘要 |
In a dot matrix line printer, a pair of pin tractors for feeding a print paper are operatively connected to a paper feed motor, and a tension roller mechanism disposed beneath a platen is operatively connected to a separately provided drive motor. To eliminate a paper slack which may occur when the feeding of the print paper is stopped after creating many blank lines, the drive motor is energized for a short period of time immediately before the paper feeding is ended. The tension roller mechanism which is made up of a plurality of rollers pulls the print paper in a direction opposite the paper feeding direction to thus prevent the print paper from slackening.
