Abstract

A tape cartridge is detachably installed on a cartridge installation portion of a tape printing apparatus. A first shaft and a second shaft are disposed on the cartridge installation portion. The tape cartridge includes a printing tape that is wound on a tape core, a platen roller in which a first shaft is inserted when the tape cartridge is installed in the cartridge installation portion, and a guided portion which is guided by the second shaft when the tape cartridge is installed in the cartridge installation portion. When seen from an attaching direction of the tape cartridge, the guided portion is disposed at an opposite side of the tape core with respect to the platen roller and the guided portion is recessed on an outer peripheral surface of a cartridge casing that forms an outer shell of the tape cartridge.

First claim

What is claimed is:

1. A tape cartridge detachably installed on a cartridge installation portion of a tape printing apparatus having a first shaft and a second shaft on the cartridge installation portion, the tape cartridge comprising:
a printing tape that is wound on a tape core;
a platen roller in which the first shaft is inserted when the tape cartridge is installed in the cartridge installation portion; and
a guided portion which is guided by the second shaft when the tape cartridge is installed in the cartridge installation portion;
wherein when seen from an attaching direction of the tape cartridge,
the guided portion is disposed at an opposite side of the tape core with respect to the platen roller, and
the guided portion is recessed on an outer peripheral surface of a cartridge casing that forms an outer shell of the tape cartridge.

2. The tape cartridge according to claim 1 further comprising a pair of grasping portions which are positioned on an opposite side of the outer peripheral surface;
wherein when seen from the attaching direction of the tape cartridge, the guided portion is positioned on an opposite side over an imaginary line connecting the pair of grasping portions with respect to the platen roller and disposed at a position to which one of the pair of grasping portions farther from the platen roller is closer than the other of the pair of grasping portions.

3. The tape cartridge according to claim 2 , wherein,
the pair of grasping portions are provided on the outer peripheral surface.

4. The tape cartridge according to claim 2 , wherein,
when the tape cartridge is installed in the cartridge installation portion, the pair of grasping portions are positioned to face hollowed portions of a surrounding wall surface of the cartridge installation portion.

5. The tape cartridge according to claim 1 , wherein,
the guided portion is recessed to be formed in a substantially semi-circular shape toward a side of the platen roller.

6. A tape cartridge detachably installed on a cartridge installation portion of a tape printing apparatus having a first shaft and a second shaft on the cartridge installation portion, the tape cartridge comprising:
a printing tape that is wound on a tape core;
a platen roller in which the first shaft is inserted when the tape cartridge is installed in the cartridge installation portion; and
a guided portion which is guided by the second shaft when the tape cartridge is installed in the cartridge installation portion;
wherein when seen from an attaching direction of the tape cartridge,
the tape core is disposed between the guided portion and the platen roller, and
the guided portion is recessed on an outer peripheral surface of a cartridge casing that forms an outer shell of the tape cartridge.
