Abstract
Abstract There is disclosed a thermal transfer recording apparatus (102) in which the ratio of amount of transportation of ink sheet (14) to that of recording sheet (11) is varied according to a measured condition, for example head temperature, of the apparatus. When the temperature or humidity is higher, facilitating the ink transfer from the ink sheet, the ink sheet is advanced by a smaller amount to economize the consumption of the ink sheet.

Claim 18
Dependent Claim
180 words
A thermal transfer recording apparatus for recording an image on a recording medium by transferring ink thereto from an ink sheet, comprising: first transport means for transporting recording medium of a continuous web form; second transport means for transporting said ink sheet with respect to said recording medium; recording means for acting on said ink sheet transported by said ink sheet transport means and for recording an image on said recording medium; wherein said recording and said ink sheet are transported at the image recording with respective amounts of transportation satisfying a first relationship; cutter means for cutting the recording medium after image recording; first control means for controlling said first transport means so as to transport said recording medium by a first predetermined amount for said cutting thereof; and second control means for controlling said second transport means so as to transport said ink sheet by a second predetermined amount in response to the transportation of said recording medium after the image recording; wherein the relationship between said first and second predetermined amounts is different from said first relationship.
Claim 19
Dependent Claim
