A tape cassette that includes a housing having a top surface, a bottom surface, a front wall, a tape feed exit located on the front wall, and an arm portion formed by the front wall and an arm rear surface behind the front wall. The arm portion partially surrounds an opening extending from the top surface to the bottom surface behind the front wall, and a tape feed path passes through the arm portion from an upstream portion of the arm portion to a downstream end of the arm portion. The tape cassette also has a tape included at least partially in the housing and configured to be fed along the tape feed path extending to the tape feed exit, and a first aperture formed on a bottom edge of the front wall and positioned downstream of an upstream end of the opening. |

1. A tape cassette, comprising:
a tape; a housing having a top surface, a bottom surface, a front wall connected with the top surface at a top edge of the front wall and with the bottom surface at a bottom edge of the front wall, a tape feed exit located on the front wall, and an arm portion formed by the front wall and an arm rear surface behind the front wall, wherein the tape is included at least partially in the housing and is configured to be fed along a tape feed path to the tape feed exit, wherein the arm portion partially surrounds an opening extending from the top surface to the bottom surface behind the front wall, wherein a first portion of the tape feed path passes through the arm portion from an upstream, in the tape feed path, end of the arm portion to a downstream, in the tape feed path, end of the arm portion, and wherein the tape in the first portion of the tape feed path is configured to be fed in a first feed direction; a roller, wherein an axis of the roller is perpendicular to the top surface and the bottom surface; a first aperture formed on both the bottom edge of the front wall and a front edge of the bottom surface, the first aperture being positioned downstream, in the first feed direction, of the upstream end of the arm portion, the downstream end of the arm portion being upstream, in the tape feed path, of the roller; a second aperture on the front wall, wherein the second aperture is located downstream, in the first feed direction, of the first aperture; a latching portion on the front wall, wherein the latching portion and one of the first aperture and the second aperture are located in a common trench in the front wall; and a rear indentation indented from a rear portion of the bottom surface toward the top surface up to a ceiling surface, a position of a portion of the rear indentation in the first feed direction being on a position of a virtual straight line in the first feed direction, the virtual straight line being orthogonal to the bottom surface and passing through the first aperture. |
