Tape cassette

A tape cassette comprising:na generally rectangular box-like housing having a top wall, a bottom wall, and a side wall defining a periphery of the housing;first and second cavities extending from respective openings provided in the bottom wall and disposed between a tape containing area and the periphery at opposite ends of a diagonal of the generally rectangular box-like housing, the tape containing area being defined within the periphery, and the diagonal connecting a first corner portion and a second corner portion of the generally rectangular box-like housing, the second cavity being defined by a wall extending from the bottom wall toward the top wall, wherein the second cavity extends along a line perpendicular to the bottom wall and is formed as a through-hole that extends through the top wall and the bottom wall along the line perpendicular to the bottom wall;at least one tape wound and mounted within the housing in the tape containing area, the at least one tape including a first tape substantially disposed in a first area, the first tape having a hole at a center of winding, and the first area being one of two areas formed by dividing the housing with respect to a line connecting the first and second cavities;a third cavity that extends in the hole of the first tape from the bottom wall; anda cylindrically shaped tape feed roller rotatably disposed between the top wall and the bottom wall to draw out the at least one tape and having an insert hole opening in the bottom wall via the first cavity.

A tape printer comprising:na tape cassette that includes:na generally rectangular box-like housing having a top wall, a bottom wall, and a side wall defining a periphery of the housing;first and second cavities extending from respective openings provided in the bottom wall and disposed between a tape containing area and the periphery at opposite ends of a diagonal of the generally rectangular box-like housing, the tape containing area being defined within the periphery, and the diagonal connecting a first corner portion and a second corner portion of the generally rectangular box-like housing, the second cavity extending from the bottom wall to the top wall;at least one tape wound and mounted within the housing in the tape containing area, the at least one tape including a first tape substantially disposed in a first area, the first tape having a hole at a center of winding, and the first area being one of two areas formed by dividing the housing with respect to a line connecting the first and second cavities;a third cavity that extends in the hole of the first tape from the bottom wall; anda cylindrically shaped tape feed roller rotatably disposed between the top wall and the bottom wall and having an insert hole opening in the bottom wall via the first cavity;a cassette housing portion in which or from which the tape cassette is installable or removable in an installation/removal direction, the installation/removal direction being a direction in which the top wall and the bottom wall are opposing each other;a tape feeding device that is configured to draw out the at least one tape of the tape cassette installed in the cassette housing portion along a predetermined feed path;a printing device that is configured to perform printing on a print medium tape of the at least one tape fed by the tape feeding device at a print position on the predetermined feed path;three guide shafts that are configured to be inserted in the first, second and third cavities and guide the tape cassette when the tape cassette is installed in or removed from the cassette housing portion in the installation/removal direction, the three guide shafts including;na first guide shaft disposed at a first position that opposes the first cavity when the tape cassette is installed in the cassette housing portion, the first guide shaft being configured to be inserted in the tape feed roller to rotatably support the tape feed roller via the first cavity and transmit a rotational drive force caused by the tape feeding device to the tape feed roller, thereby causing the tape feed roller to draw out the at least one tape;a second guide shaft disposed at a second position that opposes the second cavity when the tape cassette is installed in the cassette housing portion, the second guide shaft having a length that is greater than a length of the second cavity extending from the bottom wall to the top wall; anda third guide shaft disposed at a third position that opposes the third cavity when the tape cassette is installed in the cassette housing portion.
