A tape cassette includes a box-like housing, a tape mounted within the housing, a hole and a first indicator portion. The housing includes a top wall having a top surface, a bottom wall having a bottom surface and opposing the top wall, and a front wall having a specified height and being formed along peripheries of the top wall and the bottom wall. The hole is provided in the front wall. The first indicator portion includes at least one first aperture and indicates a first element among a plurality of elements of a type of the tape. The first indicator portion is provided in a portion, spaced from the front wall, of the bottom wall. The hole and the one first aperture is located to intersect a virtual line orthogonal to the front wall when viewing along a vertical direction orthogonal to the top wall and the bottom wall.

A cassette includes a printing tape roll being rotatable and into which a printing tape as a medium to be printed is wound, and an outer peripheral wall disposed on one side in a first direction relative to the printing tape roll. The first direction is a width direction of the printing tape. The outer peripheral wall includes a first side wall extending in a second direction orthogonal to the first direction, a second side wall extending in a third direction orthogonal to the first direction and intersecting with the second direction, and a recess wall defining a recess extending from the second side wall toward one side in the second direction. The recess extends in the third direction on one side in the second direction further than the second side wall. At least a portion of the recess overlaps the printing tape roll in the first direction.

A cassette includes: a case including a first layer and a second layer and having a head space at the first layer; and a roll disposed at the second layer and into which a medium to be printed is wound about a rotation axis in a winding direction. The medium to be printed includes a to-be-printed layer and a release layer, and is disposed at the case such that the to-be-printed layer is on an inner side thereof and the release layer is on an outer side thereof in the winding direction. The case has a conveyance path for conveying the medium to be printed. The conveyance path is defined such that the medium to be printed is conveyed in the winding direction from the roll to the head space through an opening defined at a boundary between the first layer and the second layer in the case.

An auxiliary tape cassette includes: an auxiliary tape; and a case. The auxiliary tape is used for printing on a printing tape. The case accommodates therein at least a part of the auxiliary tape. The case has: a discharge opening; and a guide part. The discharge opening discharges the printing tape to an outside. The guide part guides the printing tape supplied from an outside of the case toward the discharge opening. The guide part has a curvature forming member that causes the printing tape to be curved such that a portion in a width direction of the printing tape is distended in a thickness direction by contacting the printing tape.

A tape cassette that includes a housing having a front wall and a tape feed exit located on the front wall, a tape included at least partially within the housing, and a pressing portion and a first non-pressing portion on the front wall. The pressing portion and the first non-pressing portion are positioned to oppose tape type detecting switches of the label printer when the cassette is in the label printer. 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. The first non-pressing portion is a planar area of the front wall extending in a tape width direction from a top surface of the housing to a bottom surface of the housing.

The present invention embraces printers such as hand-held printers and mobile/portable printer. One exemplary embodiment includes “print as you glide” (PAYG) devices. Such printers may comprise a modular print engine that is removable from the printer and may allow a user to easily access and load the ribbon in the mobile print engine. The modular print engine may comprise a modular print head and an encoder that may determine the movement of the print head relative to a stationary media. When a printer is pressed against the media, the print head's burn line may be resting on the media. When the printer is stationary relative to the media, the encoder may not trigger the printing. Once PAYG is being slid or glided across the media, the encoder may start to rotate and then send a signal to a processor, causing the printer to start printing.
