Thermal inked ribbon printer mechanism
First Claim
1. A thermal printer for printing patterns on recording surface by transferring ink onto the recording surface, said printer comprising:
- ink ribbon having an ink layer;
energy-applying means having a distal end which is linearly elongated and which contacts the ink ribbon when the printer is set in a recording mode, for applying recording energy to the ink ribbon through the distal end, whereby that portion of the ink layer which contacts the recording surface along said linearly elongated distal end is transferred onto the recording surface;
drive means for driving said energy-applying means at a first drive speed in a first direction crossing linearly elongated distal end in a first mode, and at a second drive speed in a second direction, which is opposite to the first direction, in a second drive mode, such that the distal end of said energy-applying means slides on the ink ribbon; and
ribbon feeding means for continuously feeding the ink ribbon in the second direction, thereby to move the ink ribbon at a first feeding speed relative to the recording surface while said energy-applying means is driven in the first drive mode, and at a second feeding speed relative to the recording surface, the second feeding speed being faster than the first feeding speed, while said energy-applying means is driven in the second drive mode.

Abstract
In a thermal ink transfer printer, a print head and ink ribbon are mounted on a carriage which is moved at a first speed in a first direction along a recording paper in a first recording mode and also moved at the first speed in a second direction along the recording paper in the second recording mode. The ink ribbon is continuously fed in the second direction in the first and second modes and slides on the distal end of the print head so that ink is transferred from the ink ribbon onto the paper. Thus, the ink ribbon can be moved, relative to the paper, at a first speed and at a second speed which is different from the first relative speed.
