Description

  The present invention relates to an ink ribbon cutting device and an ink ribbon supply device that make an ink ribbon used in a printer into pieces.

  In recent years, in a printer using an ink ribbon, a print mark remains on a used ink ribbon, and in order to prevent leakage of personal information and confidential information, it is cut into pieces by a cutting device. Ink ribbons of various widths are prepared according to the printer to be used, and when the used ink ribbon is cut into pieces by the cutting device, the narrow ink ribbon can be supplied without unwinding. desired.

  Conventionally, there are various printers that use narrow ink ribbons, for example, handy type printers, and such ink ribbons are mostly used in a cassette. In general, there are quite a few printers that use ink ribbons with a width equivalent to one or two lines when printing on general-purpose cards such as national health insurance cards and driver's licenses. In many cases, the tape is simply wound on a winding core having no guide reel in the width direction.

  On the other hand, various techniques for supplying a long and narrow tape instead of a used ink ribbon are also known. For example, as in Patent Document 1, there is known a configuration in which a first roll obtained by winding a long print-receiving tape around a tape cartridge is supported by a first bracket portion so as to be rotatable in a vertical direction and fed out. . Further, as in Patent Document 2, a hole provided in a shaft core portion of a tape reel around which a tape is wound is fitted to a reel fixed shaft fixed in a horizontal direction with respect to a shaft base, and the tape reel is mounted. A configuration in which the tape reel is set in an upright state and freely rotates the tape reel is known.
