ABSTRACT:
A thermal transfer printing mechanism for use in a facsimile device includes a separating guide surface that is formed having a curve having a radius of curvature of not more than 1.2 mm. Consequently, the acceleration in a separating direction of an ink film separated from an image receiving sheet by the separating guide surface is increased, and the ink film is smoothly separated from the image receiving sheet. The separating guide surface may be formed as a bent thin plate, an embossed portion, a deformed edge of a supporting member, a plastic attachment, or a plastic tape. The separating guide surface is formed as a curve continuing from a feeding guide surface, and the feeding guide surface bends the sheet and the ink ribbon from a plane connecting a contact line of a thermal head and the ink ribbon and a contact line of the sheet and a sheet guide member provided downstream of the separating guide surface.
