Abstract
A printer prints images on a printing medium having a mark. The printer includes an optical sensor, a feeding section, a controller, and a printing section. The optical sensor is operable to generate a signal based on a position of the mark of the printing medium with respect to the optical sensor. The feeding section is operable to perform feeding of the printing medium. The controller is operable to control the feeding of the printing medium based on the signal. The printing section is operable to print images on the printing medium.
Claims10
A printer for printing on a printing medium having a mark, comprising:
- an optical sensor operable to generate a signal based on a position of the mark of the printing medium with respect to the optical sensor;
- a feeding section operable to perform feeding of the printing medium;
- a controller operable to control the feeding of the printing medium based on the signal;
- and
- a printing section operable to print images on the printing medium,
- wherein
- the optical sensor is operable to generate the signal by sensing a change of transmissivity of the printing medium;
- the optical sensor is a CCD line sensor having a longitudinal direction along which a plurality of sensor cells constituting the CCD line sensor are provided;
- the mark is a stripe drawn on the printing medium;
- the stripe is substantially a line;
- the line is drawn substantially perpendicular to a feeding direction along which the feeding section feeds the printing medium;
- the line and the longitudinal direction of the CCD line sensor intersect at an angle which is substantially non-perpendicular;
- and
- the line traverses all of the sensor cells while the printing medium is being fed.
A printer for printing on a printing medium having a mark, comprising:
- means for generating a signal based on a position of the mark of the printing medium with respect to an optical sensor;
- means for feeding the printing medium;
- means for controlling the feeding of the printing medium based on the signal;
- and
- means for printing images on the printing medium;
- wherein
- the optical sensor is operable to generate the signal by sensing a change of transmissivity of the printing medium;
- the optical sensor is a CCD line sensor having a longitudinal direction along which a plurality of sensor cells constituting the CCD line sensor are provided;
- the mark is a stripe drawn on the printing medium;
- the stripe is substantially a line;
- the line is drawn substantially perpendicular to a feeding direction along which the feeding section feeds the printing medium;
- the line and the longitudinal direction of the CCD line sensor intersect at an angle which is substantially non-perpendicular;
- and
- the line traverses all of the sensor cells while the printing medium is being fed.
