Abstract

A tape cassette that includes a housing having a top surface, a bottom surface, a tape feed path, a front wall, and a tape feed exit adjacent to the front wall configured to expose a tape guided in the housing along the tape feed path. The tape cassette also includes a tape at least partially included within the housing and configured to be fed along the tape feed path to the tape feed exit, a first aperture, formed on the front wall above a first centerline bisecting the front wall into top and bottom halves, and to the right of a second centerline on the front wall bisecting the housing into right and left halves, and a second aperture, formed on the front wall to the left of the second centerline, wherein at least a portion of the second aperture is below the first centerline.

First claim

What is claimed is:

1. A tape cassette, comprising:
a housing having a top surface, a bottom surface, a tape feed path, a front wall, a rear wall opposing the front wall, and a tape feed exit adjacent to the front wall, the top surface and the bottom surface being generally orthogonal to a first direction, the front wall and the rear wall forming a periphery of the housing and being generally orthogonal to the top surface and the bottom surface;
a tape at least partially included within the housing and configured to be fed along the tape feed path to the tape feed exit, the tape feed exit being configured to expose a portion of the tape;
a first aperture formed on the front wall, the first aperture being located above a first centerline bisecting the front wall into top and bottom halves and being located right of a second centerline bisecting the housing into right and left halves;
a second aperture formed on the front wall, the second aperture being located left of the second centerline, wherein the second aperture intersects the first centerline and at least a portion of the second aperture is below the first centerline; and
a ceiling surface intersecting the rear wall and being generally orthogonal to the first direction, the ceiling surface being separated from the top surface and the bottom surface in the first direction and positioned between the top surface and the bottom surface in the first direction, the ceiling surface having a bottom aperture, the bottom surface having a rear indentation indented from a rear portion of the bottom surface toward the top surface up to the ceiling surface in the first direction, a first portion of the ceiling surface being located right of the second centerline and a second portion of the ceiling surface being located left of the second centerline.

2. The tape cassette of claim 1 , wherein at least a portion of the first aperture is disposed at a position that opposes the tape in a second direction that is generally orthogonal to the front wall.

3. The tape cassette of claim 2 , further comprising:
a third aperture formed as an indented section of the housing, the indented section being indented rearward from the front wall and also indented upward from a bottom edge of the front wall, wherein at least a portion of the third aperture is located below the first centerline and right of the second centerline.

4. The tape cassette of claim 1 , further comprising:
a third aperture formed as an indented section of the housing, the indented section being indented rearward from the front wall and also indented upward from a bottom edge of the front wall, wherein at least a portion of the third aperture is located below the first centerline and right of the second centerline.

5. The tape cassette of claim 1 , wherein the first aperture is a latching aperture configured to receive a cassette latch of a label printer, and wherein the second aperture is a tape type indicator aperture.

6. A tape cassette for use with a label printer having a cassette latch for engaging the tape cassette, and a plurality of tape type detecting switches each having two possible states, the tape cassette comprising:
a housing having a top surface, a bottom surface, a tape feed path, a front wall, a rear wall opposing the front wall, and a tape feed exit adjacent to the front wall, the top surface and the bottom surface being generally orthogonal to a first direction, the front wall and the rear wall forming a periphery of the housing and being generally orthogonal to the top surface and the bottom surface;
a tape at least partially included within the housing and configured to be fed along the tape feed path to the tape feed exit, the tape feed exit being configured to expose a portion of the tape;
a latching portion formed on the front wall, the latching portion being located above a first centerline bisecting the front wall into top and bottom halves and being located right of a second centerline bisecting the housing into right and left halves, and being configured to receive the cassette latch of the label printer;
a pressing portion on the front wall and a first non-pressing portion formed on the front wall, wherein the pressing portion and the first non-pressing portion are positioned to oppose the tape type detecting switches of the label printer when the tape cassette is in the label printer,
wherein the pressing portion is configured to change a state of an opposing one of the tape type detecting switches, and the first non-pressing portion is configured to avoid changing a state of an opposing one of the tape type detecting switches, when the tape cassette is in the label printer, and
wherein the first non-pressing portion is located left of the second centerline, wherein the first non-pressing portion intersects the first centerline and at least a portion of the first non-pressing portion is below the first centerline; and
a ceiling surface intersecting with the rear wall and being generally orthogonal to the first direction, the ceiling surface being separated from the top surface and the bottom surface in the first direction and positioned between the top surface and the bottom surface in the first direction, the ceiling surface having a bottom aperture, the bottom surface having a rear indentation indented from a rear portion of the bottom surface toward the top surface up to the ceiling surface in the first direction, a first portion of the ceiling surface being located right of the second centerline and a second portion of the ceiling surface being located left of the second centerline.

7. The tape cassette of claim 6 , further comprising:
a second non-pressing portion formed as an indented section of the housing, the indented section being indented rearward from the front wall and also indented upward from a bottom edge of the front wall,
wherein the second non-pressing portion is positioned to oppose a corresponding one of the tape type detecting switches of the label printer when the tape cassette is in the label printer,
wherein the second non-pressing portion is configured to avoid changing a state of the opposing one of the tape type detecting switches, when the tape cassette is in the label printer, and
wherein at least a portion of the second non-pressing portion is located below the first centerline and right of the second centerline.

8. The tape cassette of claim 7 ,
wherein the pressing portion is located right of the first non-pressing portion and left of the second non-pressing portion, and wherein the pressing portion is located on the second centerline.

9. A tape cassette for use with a label printer having a cassette latch for engaging the tape cassette, and a plurality of tape type detecting switches each having ON and OFF possible states, the tape cassette comprising:
a housing having a top surface, a bottom surface, a tape feed path, a front wall, a rear wall opposing the front wall, and a tape feed exit adjacent to the front wall, the top surface and the bottom surface being generally orthogonal to a first direction, the front wall and the rear wall forming a periphery of the housing and being generally orthogonal to the top surface and the bottom surface;
a tape at least partially included within the housing and configured to be fed along the tape feed path to the tape feed exit, the tape feed exit being configured to expose a portion of the tape;
a latching portion formed on the front wall, the latching portion being located above a first centerline bisecting the front wall into top and bottom halves and being located right of a second centerline bisecting the housing into right and left halves, and being configured to receive the cassette latch of the label printer;
