Tape cartridge

A tape cartridge configured to be detachably installed on a tape printing apparatus provided with a detection portion which detects attribute information of the tape cartridge when the tape cartridge is installed on a cartridge installation portion of the tape printing apparatus, the tape cartridge comprising:

• a wound printing tape;
• and
• a core shaft,
• wherein
• the core shaft is positioned at an inner peripheral side of the wound printing tape,
• the core shaft includes a detection object which faces the detection portion when the tape cartridge is installed on the tape printing apparatus,
• with respect to the detection portion that includes a plurality of conductive contacts connected to a detection circuit of binarized attribute information,
• the detection object includes:
• a plurality of contact terminals including a contact portion that comes in contact with the plurality of conductive contacts when the tape cartridge is installed on the tape printing apparatus;
• and
• a conductive/non-conductive wiring portion that is connected to the plurality of contact terminals, and
• with respect to the plurality of conductive contacts disposed at equal intervals in a peripheral direction relative to a convex portion provided projectingly at the cartridge installation portion,
• the plurality of contact portions of the plurality of contact terminals are disposed at equal intervals in the peripheral direction.
