Abstract
A color printer according to the present invention includes a clutch means, an urging member and a positional alignment mechanism. The clutch means is used for engaging and disengaging a driving force used to move a paper holder means. The urging member (e.g., a spring) is used to urge the paper holder means in a direction opposite to the printing direction. The positional alignment mechanism is used for mechanically determining the position at which printing is to start on the paper when the paper holder means is disengaged from the driving force by the clutch means and is urged by the urging member in the direction opposite to the printing direction.
Claims21
A color printer comprising:
- a print medium holder means which is freely movable in a prescribed printing direction while supporting a print medium;
- a print transfer medium comprising a multiplicity of colored inks which are selectively brought into contact with, and separated from, the print medium supported on the print medium holder means;
- and
- printing means which is moved in unison with the movement of the print medium holder means while the print transfer medium is maintained in close contact with the print medium for effecting printing by selectively transferring the colored ink of the transfer medium to the print medium, the printing means comprising:
- disengaging means for disengaging a driving force used to move the print medium holder means;
- an urging member for urging the paper holder means in a direction opposite to the prescribed printing direction;
- and
- a positional alignment mechanism for mechanically determining the position at which printing is to start on the print medium using abutment contact of the print medium holder means when the holder means is disengaged from the driving force and is urged by the urging member in the direction opposite to the prescribed printing direction.
