A tape cassette includes a cassette case, a tape roll, an ink ribbon, an arm portion, a long hole, and a ribbon take-up spool. A first distance, which is a length of the long hole in a left-right direction, is larger than a second distance, which is a length from a right side surface of the cassette case to a right side end portion of the long hole. A center of gravity of the tape cassette is located in a specific area, which is an area whose both end positions in the left-right direction are the same as both left and right side end portions of the long hole, and which extends in a front-rear direction of the cassette case. The right side end portion of the long hole is located further to the right than a center of the ribbon take-up spool. |

1. A tape cassette comprising:
a cassette case that has a top surface, a bottom surface, a front surface, a rear side, a left side surface and a right side surface, and that includes a top case having a top plate that forms the top surface and a bottom case having a bottom plate that forms the bottom surface, the cassette case having a left-right direction extending between the left and right side surfaces, an up-down direction extending between the top and bottom surfaces and a front-rear direction extending between the front surface and the rear side; a tape roll that is a wound tape that is a printing medium and that is housed in the cassette case; an ink ribbon that is to be used for printing on the tape; an arm portion that includes a part of the front surface and that guides the tape toward a discharge opening along a section of a predetermined feed path, the section extending in parallel with the front surface; a long hole that extends in the left-right direction of the cassette case to the rear of and adjacent to the arm portion, that penetrates the cassette case in the up-down direction of the cassette case, and that is formed straddling a center position of the cassette case in the left-right direction, the long hole having a left side end portion and a right side end portion; and a ribbon take-up spool that is adapted to wind the ink ribbon that has been used for printing on the tape; wherein a first distance, which is a length of the long hole in the left-right direction, is larger than a second distance, which is a length from the right side surface of the cassette case to the right side end portion of the long hole, a center of gravity of the tape cassette is located in a specific area, which is an area whose both end positions in the left-right direction are the same as both the left and right side end portions of the long hole, and which extends in the front-rear direction of the cassette case, and the right side end portion of the long hole is located further to the right than a center of the ribbon take-up spool. |
