A thermal transfer printing apparatus includes an ink cassette having an ink supply roll and an ink take-up roll, and a thermal head for pressing ink paper, fed from the ink supply roll, against printing paper so as to transfer ink in the ink paper to the printing paper through heating. The ink paper subjected to the transfer is peeled from the printing paper, and then is taken up by the ink take-up roll. This apparatus further includes a generally V-shaped peel pawl provided on the thermal head, and an ink guide provided on the ink cassette. The ink paper subjected to the transfer is peeled from the printing paper by the peel pawl and the ink guide. The printing paper thus peeled is taken up by the ink take-up roll via the ink guide. With this construction, the angle of the peel pawl relative to the printing paper can be made close to 90.degree., thereby reducing a peel force and effecting the transfer satisfactorily.
A thermal transfer printing apparatus including an ink cassette having an ink supply roll and an ink take-up roll, and a thermal head having a heating position for pressing ink paper having a width, fed from said ink supply roll at a supplied angle, against printing paper so as to transfer ink in said ink paper to said printing paper through heating, said ink paper subjected to said transfer being peeled from said printing paper at an angle, and then being taken up in a direction of travel by said ink take-up roll;
A thermal transfer printing apparatus including an ink cassette having an ink supply roll and an ink take-up roll, and a thermal head for pressing ink paper, fed from said ink supply roll, against printing paper so as to transfer ink in said ink paper to said printing paper through heating, said ink paper subjected to said transfer being peeled from said printing paper, and then being taken up by said ink take-up roll;
A thermal transfer printing apparatus comprising an ink cassette which includes a supply roller holder feeding ink paper, having a width, in a direction of travel, a take-up roller holder, and at least one ink guide provided between said supply roller holder and said take-up roller holder and extending along the width of the ink paper so as to change the direction of travel of said ink paper, wherein
