Title: Thermal printer
Inventor: SATO HIROYASU
IPC: B41J2/32
Filed: 2000-12-06
Abstract: PROBLEM TO BE SOLVED: To reduce a density unevenness and prevent an increase of an unnecessary printing time. SOLUTION: A head temperature TH of a thermal head and an environmental temperature in the periphery TA are measured before recording each color image. An approach distance L necessary for emitting heat stored in a member which comes in contact with a color thermal recording paper 20 at the recording time of the image is calculated from each of the temperatures TH and TA. The color thermal recording paper 20 is pressed at a pressing start position P2 by the thermal head and a platen roller. The thermal head is pressed and approached to a recording start position P1 without being driven. The heat stored in the member which comes in touch with the color thermal recording paper 20 is emitted to the color thermal printing paper 20 during the pressing and the approach, so that the density unevenness at the recording time of the image is reduced.  Moreover, since unnecessary pressing and approach is not carried out, the printing time is prevented from increasing.
