There are provided a tape cartridge which can be changed into a compact
shape for storage or transport, or makes a printing tape and a laminating
tape replaceable, and at the same time facilitating the handling of them,
a tape cartridge capable of holding an unrolled portion extending over a
relative long distance in a proper attitude, a tape cutting device
including the tape cartridge, and a tape printing apparatus including any
of the above tape cartridges or having a structure making itself free from
spoiling the print quality. A casing of a tape cartridge accommodating at
least one roll of tape such that the at least one roll of tape can be
unrolled therefrom comprises a hinge mechanism arranged at a
longitudinally intermediate portion thereof, for allowing the tape
cartridge to be folded. A tape-holding member protrudes from a casing, for
holding an end of an unrolled portion of a roll of tape rolled out from
the casing for enabling the tape to be rolled out therefrom, thereby
ensuring mounting of the roll of tape in the cartridge compartment with
the unrolled portion rolled out from the casing. An unrolled portion of a
roll of laminating tape is laminated onto an unrolled portion of a roll of
a printing tape. A tape-supporting frame rotatably supporting at least one
of these rolls of tapes is removably mounted in a casing for removably
accommodating these rolls of tapes.
