Definitions

  • Present invention relates to an ink ribbon used in a print device for printing characters and other images on a printing medium using a thermal head and based on inputted print information.
  • Japanese Laid-Open Patent Application No. HEI-5-84994 describes a tape-shaped label producing device for printing characters and marks, inputted using a keyboard, for example, onto a tape-shaped printing medium using an ink ribbon and a thermal head.
  • This type of label producing device includes a keyboard, a display, and a thermal printing type printing mechanism.
  • characters and marks can be printed on printing tapes, which serve as a printing media, in a variety of character sizes and fonts. Examples of print tapes include tapes with widths of 6, 9, 12, 18, or 24 mm.
  • the tape-shaped labels produced by printing characters and texts in the above described manner need not to be used as labels for the spines of files.
  • the tape-shaped labels are also appropriate for attaching to cassette tapes, video tapes, or to their cases. Because these tape-shaped labels have a variety of applications, there has been a demand for producing colorful labels, wherein a portion of the characters or text character trains are printed in colors changed according to genre or recorded content of the file or tape to which the label is attached.
  • the following two methods can be used to print characters and texts in a plurality of colors.
  • the first method will be referred to as multi-color printing and the second method will be referred to as full-color printing, hereinafter.
  • the label producing device is configured so as to able to both feed and rewind the print tape.
  • a ribbon cassette housing the ink ribbon and a separate tape cassette housing the print tape are configured so that the ribbon cassette is detachably mountable in the tape cassette.
  • Multi-color printing is performed while exchanging different colored ribbon cassettes.
  • the user must have a ribbon cassette for each different color set to the text and characters to be printed, when he or she sets a great number of colors to the text, he or she must purchase all of the corresponding ribbon cassettes, which places a great burden on the user. Otherwise, the user must limit the number of colors he sets to the text. Additionally, when the user purchases a great number of ribbon cassettes and sets many different colors to the text, he or she must exchange ribbon cassettes for each color to be printed, which is very troublesome.
  • each ink ribbon is serially divided into a plurality of regions, each region being coated with ink in one of the three primary colors.
  • Full-color printing is performed by overlapping the three primary colors. Using this method, printing can be performed in a plurality of colors using only the three primary colors. Moreover, there is no need to exchange ink ribbon cassettes for each printing of a different color. Therefore, this method is very easy and convenient.
  • indication portions 314, 315, 316 are formed on the ink ribbon for distinguishing which color is disposed in each region.
  • Each indication portion 314 to 316 includes sensor marks, such as vertical lines having the same width.
  • the tape-shaped label producing device is provided with a transmission type photo sensor for determining the ink color using the distinction portions 314 to 316.
  • the type of color of the corresponding region is determined by using the photosensor to count the number of sensor marks, that is, the number of vertical lines.
  • JP 63-222883 (A) discloses an ink ribbon according to the preamble of claim 1.
  • US-5009531 discloses a color ink ribbon including color recognition marks and ribbon speed detection marks, which are used together to determine the identity of the subsequent color portion.
  • JP-01101180 an ink film is described comprising first and second markers for a determination of ink colors which is accomplished by measuring the length of the corresponding markers.
  • a detection of the end of the color ribbon is not disclosed.
  • an ink ribbon according to claim 1 a ribbon cassette according to claim 3, a combination of an ink ribbon cassette and a tape cassette according to claim 6, and a combination of a tape-shaped label producing device and an ink ribbon cassette according to claim 9.
  • ink color is determined based on information obtained from a mark common to all, and so unrelated to any, ink colors and a mark peculiar to each particular color.
  • Each mark can be formed in a narrow space so that the region required for the distinction portion can be reduced. Consequently, the usable region of the ink ribbon can be increased so that running costs of the ink ribbon can be reduced.
  • the region required for the ink color distinction portion can be reduced. Consequently, the usable region of the ink ribbon can be increased so that running costs of the ink ribbon can be reduced.
  • the above-described ink ribbon is housed in an ink ribbon case in a ribbon cassette.
  • this type of ribbon cassette is used mounted in a tape-shaped label producing device, because usable region of the ink ribbon is increased, more printing can be performed using this type of ribbon cassette than using a ribbon cassette housing a conventional ink ribbon of the same length.
  • the ribbon cassette can be used mounted in a tape-shaped label producing device and the amount of printing on the ink ribbon and the print tape can be increased compared to the conventional situation.
  • the above-described ink ribbon cassette is used in combination with a tape cassette.
  • the same tape cassette can be used for used for multi-color printing, wherein printing is performed by exchanging different color ribbon cassettes, and for full-color printing, wherein colors are reproduced by overlapping three primary colors using the ribbon cassette according to the present invention.

  • Springs 66b are provided in the roller holder 67. The springs 66b urge both tip portions in the axial direction of the moveable case 666 upward as viewed in Fig. 12 (B). For this reason, the tape feed subroller 66 is urged with respect to the tape drive roller 42 at an urging force uniform in the axial direction.

  • the solenoid 80 is operated so that the roller holder 67 is pivoted into its released position. Also, the tape drive motor 44 is rotated in the counterclockwise direction so that the gear 47 rotates in the counterclockwise direction. In association with this, the gear 301 rotates in the clockwise direction and the pivot lever 302 moves in the same direction so that the gear 306 and the gear 48 are separated from each other and the ribbon take-up cam 42 stops rotating. It should be noted that a stopper 304 is formed on n the pivot lever 302. The stopper 304 stops movement of the pivot lever 302 by abutting against an abutment rib 305 provided to the main frame 11.
  • a clutch spring 60 which links the ribbon take-up cam 42 and the gear 48 is a coil spring wrapped around the periphery of the ribbon take-up cam 42.
  • the gear 48 is rotated in the counterclockwise direction, then friction between the clutch spring 60 and the rotational shaft 42a causes the ribbon take-up cam to rotate with the gear 48.
  • the ribbon take-up cam 42 rotates slower than the gear 48 as a result of the external forces, then the winding of the clutch spring 60 will loosen. As a result, slip will be generated between the ribbon take-up cam 42 and the clutch spring 60. In this case, the ribbon take-up cam 42 will be rotated by the external force and not by the gear 48. With this configuration, take-up speed of the ink ribbon is determined by transport speed by the platen roller 65.
  • the platen gear 65a starts to rotate before the tape feed subroller 66a, then looseness of the print tape 22 will be generated between the tape feed subroller 66 and the platen roller 65.

Because the gear 55a rotates slightly later than the gear 55b, the platen gear 65a rotates later than the tape feed subroller 66a. For this reason, even if there is gear backlash, the tape feed subroller 66 will reliably start to rotate before the platen roller 65.
