Abstract

A tape cassette that includes a housing having a top surface, a bottom surface and a front surface, a wound tape mounted within the housing, a printer head holder insertion portion that is a space extending through the housing in a vertical direction and having an oblong rectangular shape in a plan view, the oblong rectangular shape extending parallel to the front surface, and a printer first support receiving portion connected to a first end of the printer head holder insertion portion and facing the printer head holder insertion portion in a first direction that is parallel to the front surface, the first end being positioned on an upstream side of the printer head holder insertion portion in a feed direction of the tape, the printer first support receiving portion being a first indentation extending from the bottom surface toward the top surface.

First claim

What is claimed is:

1. A tape cassette comprising:
a housing having a top case and a bottom case, the top case having a top surface, the bottom case having a bottom surface, the housing having a front surface and a pair of side surfaces, the front surface extending from the bottom surface toward the top surface;
a wound tape mounted within the housing;
an arm portion defined by a section of the front surface and a first wall, the first wall extending from the bottom surface toward the top surface and being spaced from the section of the front surface, the section of the front surface and the first wall forming an exit, the arm portion directing the tape generally in parallel with the front surface to the exit;
an opening extending through the housing in a first direction, the first direction being perpendicular to the top surface or the bottom surface, the opening being defined by the first wall, a second wall and a connection portion, the first wall and the second wall facing each other, the first wall being disposed between the second wall and the front surface, the second wall extending from the bottom surface toward the top surface and being generally parallel to the front surface, the connection portion connecting upstream side ends of the first wall and the second wall in a feed direction of the tape, the connection portion being positioned in an end which is connected to the upstream side ends; and
a first surface provided in the connection portion and in the bottom case, the first surface being disposed between the top surface and the bottom surface in the first direction, the bottom case having a first indentation extending from the bottom surface to the first surface.

2. The tape cassette according to claim 1 , further comprising a second surface connected to the second wall and provided in the bottom case, the second surface being disposed closer to a downstream side end of the opening than to an upstream side end of the opening in the feed direction, the second surface being disposed between the top surface and the bottom surface in the first direction, the bottom case having a second indentation extending from the bottom surface to the second surface.

3. The tape cassette according to claim 2 , wherein a first distance in the first direction between the first surface and a center position in the first direction of the tape mounted within the housing is equal to a second distance in the first direction between the second surface and the center position of the tape.

4. The tape cassette according to claim 2 , further comprising a cut-out portion provided in the second wall, the cut-out portion positioned between the first surface and the second surface in a second direction generally parallel to the front surface and generally perpendicular to the first direction.

5. The tape cassette according to claim 1 , further comprising a first lower regulating portion provided in the arm portion on an upstream side of the exit in the feed direction and spaced from the first surface in the first direction, the first lower regulating portion being configured to restrict a movement of the tape in a direction from the top surface toward the bottom surface.

6. The tape cassette according to claim 5 , further comprising a discharge guide portion that is in a most downstream position on a feed path of the tape, and guides the tape after the tape has been discharged through the exit, and discharges the tape from the tape cassette, wherein
a distance in a second direction between the first surface and the first lower regulating portion is shorter than a distance in the second direction between the exit of the arm portion and the discharge guide portion, the second direction being generally parallel to the front surface and generally perpendicular to the first direction.

7. The tape cassette according to claim 5 , further comprising a second surface connected to the second wall and provided in the bottom case, the second surface being disposed closer to a downstream side end of the opening than to an upstream side end of the opening in the feed direction, the second surface being disposed between the top surface and the bottom surface in the first direction, the bottom case having a second indentation extending from the bottom surface to the second surface, wherein
the first lower regulating portion is disposed between the first surface and the second surface in a second direction generally parallel to the front surface and generally perpendicular to the first direction, and
the first surface and the second surface are spaced from a center position of the tape in the first direction by a same distance.

8. The tape cassette according to claim 7 , further comprising:
a tape guide portion that guides the tape discharged from the exit and that is positioned on a downstream side of the exit in the feed direction and in the vicinity of the downstream side end of the opening; and
a second lower regulating portion provided in the tape guide portion and in the bottom case, the second lower regulating portion being spaced from the second surface in the first direction, the second lower regulating portion being configured to restrict the movement of the tape in a direction from the top surface toward the bottom surface.

9. The tape cassette according to claim 5 , further comprising:
a third surface provided in the connection portion, the third surface being disposed between the top surface and the first surface in the first direction and at least partially overlapping the first surface in the first direction, the top case having a third indentation extending from the top surface to the third surface; and
an upper regulating portion provided in the arm portion on an upstream side of the exit in the feed direction, the upper regulating portion being provided in the top case and spaced from the third surface in the first direction, the upper regulating portion being configured to restrict the movement of the tape in a direction from the bottom surface toward the top surface.

10. The tape cassette according to claim 1 , further comprising a third surface provided in the connection portion, the third surface being disposed between the top surface and the first surface in the first direction and at least partially overlapping the first surface in the first direction, the top case having a third indentation extending from the top surface to the third surface.

11. The tape cassette according to claim 1 , further comprising:
an ink ribbon that is to be used for printing on the tape; and
a ribbon take-up spool that is configured to wind the ink ribbon that has been used for printing on the tape, wherein
the connection portion is connected to a guide portion, the guide portion being disposed between the top surface and the bottom surface in the first direction, and
the ink ribbon is wound and mounted within the housing such that a feed path of the ink ribbon extends from the wound ink ribbon, contacts with the guide portion, and extends further in the arm portion toward the exit.

12. The tape cassette according to claim 11 , wherein
the connection portion includes a cylindrical portion formed in the bottom case and disposed above the first surface, and
the guide portion is connected to the cylindrical portion.

13. The tape cassette according to claim 1 , wherein the first wall includes a first portion and a second portion, the first portion extending from the connection portion toward the downstream side in the feed direction, the second portion extending from a downstream side end of the first portion and being inclined toward the front surface in relation to the first porti
