A tape cassette, comprising: a housing having a top surface, a bottom surface, a front surface and a pair of side surfaces; a tape (55, 57, 59) that is a print medium mounted in the housing; a tape exit that discharges, from the housing, the tape (55, 57,59) guided in the housing along a predetermined feed path, at least a part of the feed path extending parallel to the front surface; a type indicator portion provided adjacent to the tape exit and in a specified area of the front surface on an upstream side of the tape exit in a feed direction of the tape (55, 57, 59) directed along the part of the feed path extending parallel to the front surface; and a tape guide portion that is provided on a downstream side of the tape exit on the feed path, and that guides the tape (55, 57,59) that is discharged from the tape exit and exposed, the type indicator portion indicating a type of the tape (55, 57, 59) and including a plurality of lateral information sections (Y1 to Y3) and a plurality of vertical information sections (X1 to X5) defining a plurality of indicators at overlapping areas of the lateral information sections and the vertical information sections, at least one of the indicators being in the form of an indicator aperture (801, 810), the plurality of lateral information sections (Y1 to Y3) being a plurality of strip-shaped sections extending parallel to the feed direction and the plurality of vertical information sections (X1 to X5) being a plurality of strip-shaped sections extending orthogonal to the feed direction, and the length in the feed direction of the specified area is equal to or less than a tape exposure length, the tape exposure length being a distance between the tape exit and the tape guide portion and being a length of the exposed tape. a housing having a top surface, a bottom surface, a front surface and a pair of side surfaces; a tape (55, 57, 59) that is a print medium mounted in the housing; a tape exit that discharges, from the housing, the tape (55, 57,59) guided in the housing along a predetermined feed path, at least a part of the feed path extending parallel to the front surface; a type indicator portion provided adjacent to the tape exit and in a specified area of the front surface on an upstream side of the tape exit in a feed direction of the tape (55, 57, 59) directed along the part of the feed path extending parallel to the front surface; and a tape guide portion that is provided on a downstream side of the tape exit on the feed path, and that guides the tape (55, 57,59) that is discharged from the tape exit and exposed, the type indicator portion indicating a type of the tape (55, 57, 59) and including a plurality of lateral information sections (Y1 to Y3) and a plurality of vertical information sections (X1 to X5) defining a plurality of indicators at overlapping areas of the lateral information sections and the vertical information sections, at least one of the indicators being in the form of an indicator aperture (801, 810), the plurality of lateral information sections (Y1 to Y3) being a plurality of strip-shaped sections extending parallel to the feed direction and the plurality of vertical information sections (X1 to X5) being a plurality of strip-shaped sections extending orthogonal to the feed direction, and the length in the feed direction of the specified area is equal to or less than a tape exposure length, the tape exposure length being a distance between the tape exit and the tape guide portion and being a length of the exposed tape.
