Abstract
Facsimile device having a thermo-transfer foil for printing a paper sheet and having a device for reducing the foil consumption. A facsimile device (1) having paper-supply holding mechanism (2) for holding at least one sheet of paper (3) and having thermal printing device (14) for printing the sheet of paper (3) by a device of a thermo-transfer foil (7) includes additional mechanism (36) by which an unnecessary consumption of thermo-transfer foil (7) can be avoided.
Claims8
A facsimile device (1) comprising:
- paper-supply holding means (2) for holding at least one paper sheet (3),
- sheet withdrawal means (5), including a rotationally drivable sheet withdrawal roller (6), for withdrawing only one paper sheet (3) at a time from the paper-supply holding means,
- an ink transfer foil (7) fed from a supply roll (8) to a drivable take-up roll (9),
- drive means (15), including a rotationally drivable drive roller (16), for synchronously driving the ink transfer foil and a sheet withdrawn from the paper-supply holding means in a same direction,
- printing means (14) for transferring ink particles from the ink transfer foil to said paper sheet withdrawn from the paper-supply holding means and being driven synchronously with said ink transfer foil, to form a printed image,
- motor means, comprising at least one motor (18), for driving the drive roller and for driving the sheet withdrawal roller,
- a first drive transmission (29) by which the drive roller is driven by said motor means,
- a second drive transmission (30) by which the sheet withdrawal roller is driven by said motor means, and
- control means for the motor means, for activating driving in a first direction of rotation for synchronously driving the ink transfer foil and said sheet withdrawn from the paper-supply holding means,
- characterized in that the device further comprises means for inhibiting driving of the ink transfer foil by the drive roller (16) during an initial portion of the withdrawal of the sheet from the paper-supply holding means.
