Abstract

A tape cartridge configured to mounted in a tape printing apparatus includes: a cartridge case, a tape-shaped member contained in the cartridge case, an ink ribbon contained in the cartridge case, a roller contained rotatably in the cartridge case and is configured to feed the tape-shaped member outside the cartridge case by rotation, and is movable to a tape feeding upstream side in association with a retracting of the tape-shaped member into the cartridge case, a retracting prevention part cantilevered by the cartridge case on the tape feeding upstream side from the roller, and holds the tape-shaped member together with the roller moved to the tape feeding upstream side, and a ribbon guide part which is provided in the retracting prevention part. the retracting prevention part includes: a tape holding part, and an upstream base end provided at a base end of the tape holding part.

First claim

The invention claimed is:

1. A tape cartridge which is configured to be mounted in a tape printing apparatus, comprising:
a cartridge case,
a tape-shaped member which comprises a mount tape and a printing tape releasably stuck to the mount tape, and is contained in the cartridge case,
an ink ribbon which is contained in the cartridge case,
a roller which is contained rotatably in the cartridge case, is configured to feed the tape-shaped member outside the cartridge case by rotation, and is movable to a tape feeding upstream side in association with a retracting of the tape-shaped member into the cartridge case,
a retracting prevention part which is cantilevered by the cartridge case on the tape feeding upstream side from the roller so as to be elastically bent by receiving a tension of the fed tape-shaped member, and holds the tape-shaped member together with the roller moved to the tape feeding upstream side in association with the retracting of the tape-shaped member into the cartridge case, and
a ribbon guide part which is provided in the retracting prevention part in a direction in which the retracting prevention part is bent by the tension of the tape-shaped member, and is configured to guide the ink ribbon fed between the ribbon guide part and the retracting prevention part,
wherein the retracting prevention part comprises:
a tape holding part which holds the tape-shaped member together with the roller, and
an upstream base end provided at a base end of the tape holding part on the tape feeding upstream side of the tape holding part, and in a position of being overlapped with the ribbon guide part when viewed from the bending direction,
wherein a height of the tape holding part is larger than a height of the upstream base end.

2. The tape cartridge according to claim 1 , wherein:
the tape printing apparatus comprises a detection part, the tape cartridge comprises a first wall and a second wall which oppose to each other,
the retracting prevention part is provided to protrude from the second wall toward the first wall,
the tape-shaped member comprises a detection protrusion of which a lateral side partially protrudes in a tape width direction, and is contained as a tape roll wound in a roll shape in the cartridge case, and
an exposed area where the detection protrusion of the tape-shaped member delivered from the tape roll is exposed is provided on an outer surface of the first wall, such that the detection part is configured to detect a passage of the detection protrusion in a state where the tape cartridge is mounted in the tape printing apparatus.

3. The tape cartridge according to claim 2 , further comprising:
a position regulating part which is provided to a tip side of the retracting prevention part in a protruding direction, and is configured to regulate a position of the tape-shaped member on a protruding side of the detection protrusion by contacting a protruding end of the detection protrusion.
