Abstract (en)
In a heat transfer recording apparatus, the recording medium (4) and ink donor sheet (5) are drawn from separate sources and drawn together only for the recording operation. A stress absorbing roller (9) and/or brake mechanism can be used to minimize wrinkles in the thin ink donor sheet. A compact automatic/manual paper feed mechanism uses the retard roll to feed manually supplied paper, and switching between automatic and manual feed is automatic when paper is manually inserted. A control circuit maintains the donor sheet transport disabled until recording paper is detected approaching the recording station, and in the case of separate manual and automatic paper feed passages, a single sensor element covers both passages. A separating guide member is disposed adjacent the donor film at a point where its path abruptly changes, to peel off the copied paper.
