A tension detection device according to an embodiment includes a base, a support member, a continuous body, an external force detection unit, and a tension detection unit. One end or both ends of the support member are fixed to the base. The support member has an external force measurement section integrally provided at the one end or both ends thereof. The continuous body is conveyed while wound around an outer circumference of the support member. The external force detection unit is provided at the external force measurement section of the support member. The external force detection unit detects an external force. The tension detection unit detects tension of the continuous body based on a detection result from the external force detection unit.

A printing apparatus includes: a printing unit which performs printing on a medium, a main body; a conveyer which conveys the medium; a post-processing unit which performs a post-processing for the medium on which the printing has been performed by the printing unit; a first cover rotatably supported by the main body and in which at least the post-processing part is installed; a second cover arranged to be adjacent to the first cover and supported by the main body such that the second cover is rotatable coaxially with the first cover; and an engaging mechanism which changes a state of the first cover and the second cover between an engaged state and a non-engaged state.

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 printer in one example includes a thermal printhead with resistive heating elements. A motor is provided in the printer for conveying paper to the thermal printhead. A power supply is provided to supply power to the thermal printhead and the motor. A processor is configured to cause the supply of power to the motor to be paused after the supply of power to the thermal printhead exceeds a power threshold value and then to resume the supply of power to the motor after a predetermined period of time elapses after the pause of the supply of power to the motor.
