Abstract

PURPOSE:To feed ink up to the bottom of the recessed section of a form, and to improve the quality of printing by installing a smoother roller pushing a form surface against a platen while being interlocked with the drive of a printing head in order to smooth the irregularities of the printing section of the form. CONSTITUTION:An ink ribbon 5 and a printing head 6 are mounted into a carrier 7. A spring 4 being fixed so that a smoother roller 3 for smoothing the surface of a form 2 is moved freely in the direction of the arrow 9 and turned rotatably and pushing the smoother roller 3 against the surface of the form 2 is set up. The form 2 is set to a flat platen 1, and printing is conducted while the carrier 7 is shifted in the direction of the arrow 8 to the form 2. The irregularities of the surface of the form 2 are smoothed because the smooth er roller 3 is pushed in the direction of the arrow 9 by the spring 4, and the ink of the ink ribbon 5 is transferred onto the form 2 by the printing head 6. Accordingly, the irregularities of the surface of the form are smoothed, and ink is transferred, thus preventing the deterioration of the quality of printing.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a thermal transfer serial printer.

[Conventional technology]

Conventional thermal transfer printers feed paper one latin and print immediately.

[Problem to be solved by the invention]

Conventional thermal transfer serial printers did not have a mechanism to smooth out the unevenness of paper when printing on paper with severe unevenness, so the ink did not reach the bottom of the depressions on the paper.
This has the disadvantage that print quality deteriorates.

[Means to solve the problem]

The thermal transfer serial printer of the present invention is characterized in that it is provided with a smoother roller that presses the paper surface against the platen in conjunction with the drive of the print head in order to smooth out unevenness on the printing area of the paper.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a plan view of one embodiment of the present invention. career 7
There is an ink ribbon 5. in the same way as in conventional thermal transfer serial printers. It has a print head 6, and a smoother roller 3 for smoothing the surface of the paper 2 is fixed so as to be freely movable and rotatable in the direction of arrow 9. Spring 4 that presses against the surface
is installed. A paper 2 is set on a flat platen 1, and a carrier 7 prints while moving in the direction of an arrow 8 with respect to the paper 2.

FIG. 2 is an enlarged view of the print head section. The surface of the paper 2 is smoothed by the smoother roller 3 pressed in the direction of the arrow 9 by the spring 4, and then the ink from the ink ribbon 5 is applied to the paper 2 by the print head 6.
transcribed into.

〔Effect of the invention〕

As explained above, the present invention has the effect of preventing deterioration of printing quality by smoothing the irregularities on the surface of the paper and then transferring the ink.

FIG. 1 is a plan view of an embodiment of the present invention, and FIG. 2 is an enlarged view of the print head portion of the second construction drawing.

Claims (1)

[Claims] A thermal transfer serial printer comprising: a smoother roller that presses a paper surface against a platen in conjunction with the drive of a print head to smooth out unevenness on a printed portion of the paper; and means for applying force to the smoother roller.
