A thermal transfer printing apparatus includes a reading device for reading a code registered section provided on an ink sheet cassette, and a color discrimination device, a part of which is provided on a thermal head. The apparatus acts to heat an ink sheet superposed on a print paper by means of the thermal head to print an image on the print paper. The ink sheet cassette includes a pair of ink shafts on which both ends of a continuous ink sheet having a continuous film or paper with inks applied thereon are wound, and a cassette case in which the ink shafts are received, at least one of the ink shafts being adapted to be drivingly connected in the axial direction to a torque supply shaft inserted from the outside of the cassette case so that driving torque is supplied from the torque supply shaft to the ink shaft. The code registered section is composed of a first pattern portion of alternating white and black patterns and a second pattern portion in which information connecting the ink sheet is coded and recorded in line with the first pattern portion. The code registered section is provided on one of the ink shafts in the cassette case.
摘要:
A thermal transfer printer which can use both an ink sheet provided with a positioning mark to indicate the top position of a set of three color ink patches necessary for producing one image, and an ink sheet provided with no such positioning mark, without the need of switching the operation mode. The thermal transfer printer has an optical sensor which can equally detect color change between 3rd and 1st color patches for the ink sheet provided with no positioning mark and color change between a positioning mark and 1st color patch for the ink sheet provided with the positioning mark. There is also disclosed an ink sheet cassette for use in the thermal transfer printer, the ink sheet cassette accommodating the ink sheet in which a positioning mark is coated with the same color(s) of ink as those for printing and information about the color sequence of the ink coated patches for printing is also recorded in the coated pattern of the positioning mark.

During the playback operation for freezing and storing a specific frame of a picture in a memory and thereafter printing the frame, the recording medium is turned reversely for a prescribed amount according to an instruction from a printer in response to the entry of the freeze command in order to accurately search the frame at the entry of the freeze, and thereafter the recording medium is played back in normal mode. The amounts of reverse turn and the successive forward turn in normal playback are counted and compared, and when the difference has become a prescribed value, a freeze signal is produced and the frame of the picture selected by the freeze command is stored in the memory and printed when required. This control method for use in a video print system is designed so that the recording medium is turned reversely for a prescribed amount according to an instruction from the printer and then stopped until the next command is entered.
摘要:
An inked sheet cassette suitable for use in printer such as a multi-color thermal transfer-type printer. The cassette has a cassette case encasing an inked sheet constituted by a thin web-like film or paper sheet with at least one type of ink applied thereto, and a pair of reels disposed in the cassette case and constituting a supply reel and a take-up reel on which are wound the respective ends of the inked sheet. The cassette has a window provided at least in one of a portion of said cassette case adjacent to the supply reel and portion adjacent to said take-up reel so as to enable the user to visually check the diameter of the roll of the inked sheet on the reel adjacent to said window. Disclosed also is a printer suitable for use in combination with this cassette.
摘要:
A thermal ink-transfer printer is disclosed in which an ink donor sheet is wound on a supply reel. The ink donor sheet is drawn out from the supply reel and passes between a rotating drum and a thermal head and is then rolled round a winding reel. Printing paper is moved in a printing-paper transporting path formed between the rotating drum and guide means. The thermal head presses the ink donor sheet against the printing paper and heats the ink donor sheet to transfer the ink on the ink donor sheet to the printing paper. The ink donor sheet after completing the ink transfer is separated from the printing paper and rolled round the winding reel. The printing paper separated from the ink donor sheet is moved in the printing-paper transporting path. When the ink donor sheet during separation from the printing paper is erroneously drawn into a predetermined portion of the printing-paper transporting path, this erroneous operation of the ink donor sheet is detected by jam detecting means.
