Tape cartridge and tape printing apparatus

A tape cartridge to be installed in a tape printing apparatus having a print head that performs printing on a print tape, the tape cartridge comprising:

• a tape-shaped member that has the print tape and a release tape affixed to a rear side of the print tape;
• a platen roller that is rotatably provided so as to be brought into rolling-contact with a side of the release tape of the tape-shaped member, feeds by rotation the tape-shaped member held between the platen roller and the print head, and moves within a prescribed range in a tape feed direction as the tape-shaped member is paid out and drawn;
• and
• a drawing prevention portion that is provided at a position upstream of the platen roller in the tape feed direction, contacts a side of the print tape of the tape-shaped member, and holds the tape-shaped member between the drawing prevention portion and the platen roller when the platen roller moves to an upstream side in the tape feed direction as the tape-shaped member is drawn, wherein
• the drawing prevention portion is supported on one side thereof and is configured to be capable of elastically tilting to a side opposite to the platen roller.

A tape cartridge to be installed in a tape printing apparatus, the tape cartridge comprising:

• a tape-shaped member having a plurality of detection convex portions that partially projects from one end in a tape width direction;
• a cartridge case that has a first wall portion and a second wall portion facing each other and accommodates the tape-shaped member so as to make a side of the one end of the tape-shaped member positioned on a side of the first wall portion and make a side of the other end thereof positioned on a side of the second wall portion;
• a platen roller that serves as a roller rotatably accommodated in the cartridge case and paying out the tape-shaped member by rotation and is movable to an upstream side in a paying-out direction of the tape-shaped member as the tape-shaped member is drawn;
• and
• a drawing prevention portion that projects from the second wall portion at a position upstream of the platen roller in the paying-out direction of the tape-shaped member and holds the tape-shaped member between the drawing prevention portion and the platen roller when the platen roller moves to the upstream side in the paying-out direction of the tape-shaped member as the tape-shaped member is drawn, wherein
• the drawing prevention portion does not contact the detection convex portions.
