A printing cassette that is to be attached to and detached from a printing apparatus main body is provided. The printing cassette includes: a first roll in which a first tape is wound around a winding center axis parallel to a first direction; and an input gear that is disposed at a different position from the first roll in the first direction, engaging another gear, and configured to transmit a driving force of a drive shaft of the printing apparatus to the another gear. The first roll has a cylindrical shape in which a hollow portion is defined by an inner peripheral surface. The drive shaft is inserted into the hollow portion of the first roll and the input gear is engaged with the drive shaft in a state where the printing cassette is attached to the printing apparatus main body.

A printing device and the ribbon mounting mechanism thereof are disclosed. The ribbon mounting mechanism is used for mounting a first ribbon comprising a first core and a second ribbon comprising a second core having a diameter smaller than that of the first core. The ribbon mounting mechanism includes a first shaft supporting the first core of the first ribbon; a second shaft supporting the second core of the second ribbon, wherein the second shaft and the first shaft are concentrically disposed; a torque generator comprising a third shaft; a first gear set connecting the first shaft and the third shaft, and torque generated by the torque generator is transmitted to the first shaft through the first gear set; and a second gear set connecting the second shaft and the third shaft, and torque generated by the torque generator is transmitted to the second shaft through the second gear set.

A device for processing media may include a system and method for loading and unloading consumable supplies of a media processing device, and more particularly, a system and method for providing a compact form factor media processing device which provides convenient access to the replaceable components of the media processing device. A media processing device may include a base and a lid hingedly attached to the base, moveable between a closed position in which the lid is secured to the base, and an open position. A cavity may be defined between the lid and the base, where the cavity is inaccessible when the lid is in the closed position and the cavity is accessible when the lid is in the open position. The media processing device may include a ribbon positioning assembly disposed within the cavity.

An ink ribbon cartridge includes a first spool, a first case covering the first spool, a second spool, a second case covering the second spool, a first rib provided at the first case, a second rib provided at the second case, an ink ribbon, a first protrusion, and a second protrusion. The first spool extends in a first direction and the second spool extends in a second direction. The first protrusion protrudes in the first direction from an end of the first case in the first direction. The second protrusion protrudes in the second direction from an end of the second case in the second direction. The first protrusion and the second protrusion are respectively fitted in a first hole and a second hole of a first frame of a printing device in a state where the ink ribbon cartridge is attached the printing device.
