Claim:
1. A tape cassette, comprising: an ink ribbon; a take-up spool configured to take up the ink ribbon and having a first opening; a housing at least partly accommodating the ink ribbon, the housing having a top surface, a bottom surface having a second opening exposing the first opening of the take-up spool, a front wall that meets the bottom surface at a bottom edge of the front wall, a tape feed exit, and an arm portion formed by the front wall and an arm rear surface behind the front wall, wherein the arm portion, an opening inner surface behind the arm rear surface, and an opening side surface extending from the opening inner surface toward the arm rear surface partially surround a third opening extending from the top surface to the bottom surface behind the arm portion, wherein the opening inner surface is generally parallel to the front wall, wherein the front wall and the arm rear surface form the tape feed exit, and wherein a tape feed path passes through the arm portion from an upstream, with respect to the tape feed path at the front wall, portion of the arm portion to a downstream, with respect to the tape feed path at the front wall, end of the arm portion; a tape at least partially included within the housing and configured to be fed along the tape feed path extending to the tape feed exit; a first aperture formed on the bottom edge of the front wall, wherein a virtual line orthogonal to the front wall intersects the first aperture, the third opening, and the take-up spool; and a recess portion formed on the bottom surface, wherein the recess portion recesses upstream from the opening side surface in a feeding direction along the tape feed path, and wherein an upstream end of the recess portion is positioned upstream of a center of the first opening in the feeding direction, wherein the recess portion includes a first edge, a second edge, and a third edge, wherein the first edge connects to a bottom edge of the arm rear surface, wherein the second edge is opposed to the first edge, wherein a distance between the second edge and the center of the first opening is greater than a distance between the opening inner surface and the center of the first opening in a direction parallel to the bottom surface and perpendicular to the feeding direction, and wherein the third edge connects the first edge and the second edge.
