Thermal transfer recording apparatus and method that stably conveys

A thermal transfer recording apparatus for transferring an ink of an ink sheet to a recording medium to thereby effect recording of images on said recording medium, comprising:

• ink sheet conveying means for conveying said ink sheet;
• recording medium conveying means for conveying said recording medium, said recording medium conveying means having a driving torque;
• recording means for acting on said ink sheet to thereby effect recording of images on said recording medium when said recording medium and said ink sheet are held together, said driving torque causing said recording medium and said ink sheet to be separated;
• counting means for counting a quantity of driving information of image data recorded by said recording means;
• and
• control means for controlling so as to change the driving torque of said recording medium conveying means in conformity with the quantity of said driving information counted by said counting means.

A thermal transfer recording method of transferring an ink of an ink sheet to a recording medium to record images on said recording medium, comprising the steps of:

• providing recording medium conveying means for conveying said recording medium, said recording medium conveying means having a driving torque;
• acting on said ink sheet using a recording means for recording to record images on said recording medium while holding said recording medium and said ink sheet together;
• conveying said recording medium and said ink sheet;
• determining a quantity of a dot driving information;
• separating said recording medium and said ink sheet by applying said driving torque;
• and
• controlling said driving torque is conformity with said quantity of said dot driving information.

A thermal transfer recording apparatus comprising:

• a fixed full line type thermal recording head, said head selectively recording images on a recording medium;
• counting means for counting a quantity of an information to be recorded;
• and
• first moving means for moving an ink sheet past said thermal recording head in a first direction;
• and
• second moving means for moving a recording medium past said thermal recording head in a second direction, said first and said second direction being opposite to one another;
• said first and second moving means each having a corresponding moving torque wherein at least one of said first and second moving means change said corresponding moving torque in accordance with said quantity of said information to be recorded, said corresponding moving torque being increased as said quantity of said information to be recorded is increased.
