Abstract

There is provided a tape cartridge including: a tape roll including a tape and a tape core which is provided with a core hole and around which the tape is wound; and a cartridge case accommodating the tape roll, and including a first case portion having a first base wall portion and a first core projection protruding from the first base wall portion in a first direction, and a third case portion having a third base wall portion and a third core projection protruding from the third base wall portion in a third direction opposite to the first direction and inserted into the core hole, in which the tape core is provided with an insertion receiving section which is positioned on a radially outer side of the tape core with respect to the core hole and into which the first core projection is inserted.

First claim

What is claimed is:

1. A tape cartridge comprising:
a tape roll including a tape and a tape core which is provided with a core hole and around which the tape is wound; and
a cartridge case accommodating the tape roll, and including a first case portion having a first base wall portion and a first core projection protruding from the first base wall portion in a first direction, and a third case portion having a third base wall portion and a third core projection protruding from the third base wall portion in a third direction opposite to the first direction and inserted into the core hole, wherein
the tape core is provided with an insertion receiving section which is positioned on a radially outer side of the tape core with respect to the core hole and into which the first core projection is inserted, and
when the first core projection is inserted into the insertion receiving section and the third core projection is inserted into the core hole, the first core projection is positioned on the radially outer side of the third core projection with respect to the core hole.

2. The tape cartridge according to claim 1 , wherein
an outer peripheral side of a tip end portion of the first core projection is provided with an outer peripheral side inclined surface inclined with respect to the first direction, and
an inner peripheral side of the tip end portion of the first core projection is provided with an inner peripheral side inclined surface inclined with respect to the first direction.

3. The tape cartridge according to claim 1 , wherein
a tip end portion of the first core projection is inclined with respect to the first direction.

4. The tape cartridge according to claim 1 , further comprising:
an ink ribbon accommodated in the cartridge case, wherein
the cartridge case accommodates the tape roll in a replaceable manner with another tape roll, and
in an unused tape cartridge, a length of the ink ribbon is at least two times a length of the tape.

5. The tape cartridge according to claim 4 , further comprising:
a circuit substrate configured to store information indicating a remaining amount of the ink ribbon, wherein
the tape cartridge is configured to be mounted on a tape printing apparatus configured to read the information stored in the circuit substrate.

6. A tape roll configured to be accommodated in a cartridge case including a first case portion having a first base wall portion and a first core projection protruding from the first base wall portion in a first direction, and a third case portion having a third base wall portion and a third core projection protruding from the third base wall portion in a third direction opposite to the first direction, comprising:
a tape; and
a tape core provided with a core hole into which the third core projection is inserted, and around which the tape is wound, wherein
the tape core is provided with an insertion receiving section which is positioned on a radially outer side of the tape core with respect to the core hole and into which the first core projection is configured to be inserted, and
when the first core projection is inserted into the insertion receiving section and the third core projection is inserted into the core hole, the first core projection is positioned on the radially outer side of the third core projection with respect to the core hole.

7. A tape cartridge set comprising:
a plurality of tape rolls each including a tape and a tape core which is provided with a core hole and an annular recess portion positioned on a radially outer side of the tape roll with respect to the core hole and around which the tape is wound; and
a cartridge case including a first case portion having a first base wall portion and a first core projection protruding from the first base wall portion in a first direction and inserted into the annular recess portion, and a third case portion having a third base wall portion and a third core projection protruding from the third base wall portion in a third direction opposite to the first direction and inserted into the core hole, and configured to accommodate one tape roll of the plurality of tape rolls,
wherein, when the first core projection is inserted into the annular recess portion and the third core projection is inserted into the core hole, the first core projection is positioned on the radially outer side of the third core projection with respect to the core hole.
