Tape cassette

A tape cassette configured to be mounted in a printer, the tape cassette comprising:

• a housing having a first end portion and a second end portion separated from the first end portion in a first direction, and having a third end portion and a fourth end portion separated from the third end portion in a second direction, the second direction being orthogonal to the first direction;
• a tape roll held inside the housing, and disposed closer to the third end portion than to the fourth end portion in the second direction;
• a tape wound around the tape roll;
• an outlet disposed closer to the first end portion than to the second end portion in the first direction, and configured to discharge, to outside of the housing, the tape from the tape roll that has been conveyed through a detection position provided at a position facing a sensor of the printer;
• a first guide disposed closer to the fourth end portion than to the third end portion in the second direction, disposed closer to the first end portion than to the second end portion in the first end portion, and configured to guide the tape that has been conveyed through the detection position toward the outlet;
• a first opening that is open toward a first surface of the tape conveyed through the detection position;
• a second opening that is open toward a second surface of the tape, the second surface being opposite to the first surface of the tape;
• a first rotation body disposed closer to the fourth end portion than to the third end portion in the second direction, and disposed at a position adjacent to the first opening, the position adjacent to the first opening being an entrance to the detection position;
• and
• a second rotation body disposed closer to the fourth end portion than to the third end portion in the second direction, disposed further upstream than the first guide in a tape conveyance direction, and disposed at a position adjacent to the second opening, the position adjacent to the second opening being an exit from the detection position,
• wherein the second rotation body is arranged between the first guide and the first rotation body, in the first direction.
