Tape cassette including partition plate partitioning internal space of housing into first space in which tape roll is positioned and second space in which first and second gears are positioned

A tape cassette comprising:

• a tape roll in which a tape and an ink ribbon are wound together in an overlaid state, the tape roll being rotatable about a first axis extending in a first direction;
• a housing having a first opening, the housing including:
• a partition plate partitioning an internal space of the housing into a first space in which the tape roll is positioned and a second space, the first space and the second space being arranged in the first direction;
• and
• an arm positioned on an opposite side of the partition plate from the first space in the first direction, the arm having a second opening allowing the tape and the ink ribbon to be discharged through the second opening to an outside of the housing;
• a first gear positioned in the second space;
• and
• a second gear positioned in the second space, the second gear being exposed to the outside of the housing through the first opening, the second gear being configured to operate in response to an operation of the first gear.

A tape cassette comprising:

• a tape roll in which a heat-sensitive tape is wound, the heat-sensitive tape being configured to generate color when heated, the tape roll being rotatable about a first axis extending in a first direction;
• a housing having a first opening, the housing including:
• a partition plate partitioning an internal space of the housing into a first space in which the tape roll is positioned and a second space, the first space and the second space being arranged in the first direction;
• and
• an arm positioned on an opposite side of the partition plate from the first space in the first direction, the arm having a second opening allowing the heat-sensitive tape to be discharged through the second opening to an outside of the housing;
