Abstract
A printing paper guiding method and apparatus for a printer whose printing head guides printing paper when the printer performs a printing operation on printing paper. The printing paper guiding apparatus includes a plate spring having a roller installed below the printing head and a shaft formed in a transverse direction and in the center of the printing head so that the printing head can be inclined about the shaft, thereby to enable the printing paper to be smoothly pushed onto a drum and prevent the printing paper from being separated from the drum. As a result, the entire surface of the printing paper can be printed and a poor printing quality can be prevented.
Claims6
A printing paper guiding method for a printer that performs a printing on a printing paper transferred between a drum and a guide roller by means of pressing a printing head against the printing paper, said method comprising the steps of:
- inclining the printing head when a leading end of the printing paper is transferred between the drum and a printing portion of the printing head so that the printing head presses a rear portion of the leading end of the printing paper toward an inserting direction of the printing paper;
- and
- inclining the printing head toward a direction opposite to the inserting direction of the printing paper so that the leading end of the printing paper is pushed onto the drum when the leading end of the printing paper passes through an initial printing location.
A printing paper guiding apparatus of a printer, the printer including a drum having a rotation direction, a printing head and an ink film, so as to transfer printing paper to the drum thereby to perform a printing by pressing the ink film and the printing head onto the printing paper being transferred, said printing paper guiding apparatus comprising:
- first means for inclining said printing head toward an inverse direction of the rotation direction of the drum;
- and
- second means for inclining said printing head toward the rotation direction of the drum and sequentially pushing a leading end of the printing paper onto the drum as the printing head inclines.
