Tape cassette

A tape cassette comprising:

• a housing including a top case and a bottom case, the top case including a top wall and the bottom case including a bottom wall and a bottom outer wall extending from the bottom wall toward the top wall;
• a tape wound and mounted within the housing, the tape being a print medium;
• a printer head insertion portion that is a space extending through the housing in a direction perpendicular to the bottom wall and having an oblong rectangular cross-sectional shape, the oblong rectangular shape extending parallel to the front wall;
• an arm portion including a first wall portion and a second wall portion and directing the tape along a feed path between the first wall portion and the second wall portion to an exit, the first wall portion being a section of the bottom outer wall, the second wall portion being disposed between the first wall portion and the printer head insertion portion, and extending perpendicularly upwards from the bottom wall;
• a guide portion that directs the tape discharged from the exit of the arm portion toward a downstream side in a feed direction of the tape;
• a width direction regulating portion provided on the bottom case at a downstream side of the guide portion in the tape feed direction to restrict a movement of the tape in a tape width direction;
• a print surface side regulating portion provided on the bottom case at a downstream side of the guide portion in the tape feed direction to restrict the movement of the tape toward a print surface side of the tape;
• a lower joining portion provided on an upper end of the width direction regulating portion;
• and
• an upper joining portion provided on the top case to join with the lower joining portion at a position that corresponds to a position of the lower joining portion when the top case and the bottom case are joined.

• a tape feed roller rotatably disposed within the housing at a downstream side of the printer head insertion portion in a feed direction to draw out the tape;
• a width direction regulating portion provided on the bottom case at a downstream side of the tape feed roller in the feed direction to restrict the movement of the tape in the tape width direction;
• a lower joining portion provided on an upper end of the width direction regulating portion;
• and
• an upper joining portion provided on the top case to join with the lower joining portion at a position that corresponds to a position of the lower joining portion when the top case and the bottom case are joined.
