A tape support arrangement comprises a tape take up core (220) suitable for supporting a tape; and a tape supply core (210) suitable for supporting a tape (230). The supply core (210) comprises an inner surface (212), the inner surface defining an internal volume (240) of the supply core and being configured for engagement with a tape drive support. The take up core (220) is sized and shaped such that it can be located in the internal volume (240) of the supply core (210). Refer to FIG. 2.

A cartridge is installed in a tape printing device including a cartridge installation part, a printing head that is provided in the cartridge installation part and performs printing on a printing tape, and a device case, the device case having a device-side tape introduction port that introduces the printing tape from an outside to an inside of the device case and a device-side tape ejection port that ejects the printing tape to the outside of the device case. The cartridge includes a tape path through which the printing tape introduced from the device-side tape introduction port is fed toward the device-side tape ejection port in a state in which the cartridge is installed in the cartridge installation part.

A cartridge that makes it possible to simultaneously set a printing tape and a cartridge in a tape printing device. A cartridge to be installed in a tape printing device includes: a cartridge case; a cartridge-side tape introduction port that introduces a printing tape introduced from a device-side tape introduction port into the cartridge case and a cartridge-side tape ejection port that ejects the printing tape to an outside of the cartridge case toward a device-side tape ejection port in a state in which the cartridge is installed in a cartridge installation part; and a tape retention part that retains the printing tape that is introduced in advance into a tape path between the cartridge-side tape introduction port and the cartridge-side tape ejection port before the cartridge is installed in the cartridge installation part.

A printer includes, a printing portion configured to print on a print medium, a ribbon roll up shaft configured to roll up an ink ribbon used in the printing portion, a ribbon supply shaft provided movably between a first position and a second position with respect to the ribbon roll up shaft, the ribbon supply shaft configured to hold the ink ribbon to be supplied to the printing portion, and a ribbon supply shaft lock mechanism to be brought into a lock state where rotation of the ribbon supply shaft is regulated when the ribbon supply shaft is placed at the first position, and into a non-lock state where the rotation of the ribbon supply shaft is permitted when the ribbon supply shaft is placed at the second position.

A label printer and a label printing method for precise positioning thereof are provided. The label printer includes an outer shell and a label cartridge arranged inside the outer shell, a power mechanism and a control mechanism configured to control paper output of the label cartridge and winding and unwinding of a carbon ribbon, and a print head configured to realize label printing. An inner space of the label cartridge is reasonably planed, and a linear label paper output channel and a label rollback release space are arranged, thereby ensuring smoothness of paper feeding and paper rollback, and preventing label paper from wrinkling in a rollback process. A gear transmission system is improved to realize forward and reverse rotation of gears relying on the same electric motor. A photoelectric sensor with its own reflecting prism is arranged to reduce an occupied space of the label cartridge.

Disclosed is an accommodation body including: a tape roll accommodation part in which a tape roll on which a tape to be fed to a tape printing apparatus is wound is accommodated; a wall part that is provided with a tape discharge port from which the tape fed from the tape roll is to be discharged; and a cartridge accommodation part in which a ribbon cartridge that has an ink ribbon and is to be installed in the tape printing apparatus while retaining the tape fed from the tape roll is accommodated.

A printer includes, a printing portion configured to print on a print medium, a ribbon roll up shaft configured to roll up an ink ribbon used in the printing portion, a ribbon supply shaft provided movably between a first position and a second position with respect to the ribbon roll up shaft, the ribbon supply shaft configured to hold the ink ribbon to be supplied to the printing portion, and a ribbon supply shaft lock mechanism to be brought into a lock state where rotation of the ribbon supply shaft is regulated when the ribbon supply shaft is placed at the first position, and into a non-lock state where the rotation of the ribbon supply shaft is permitted when the ribbon supply shaft is placed at the second position.

A printer includes, a printing portion configured to print on a print medium, a ribbon supply shaft configured to hold an ink ribbon to be supplied to the printing portion, a ribbon roll up shaft configured to roll up the ink ribbon used in the printing portion, a partition member provided swingably, the partition member partitioning the ink ribbon and the print medium; and a ribbon supply shaft lock mechanism configured to regulate rotation of the ribbon supply shaft, wherein the ribbon supply shaft lock mechanism is switched between a lock state where the rotation of the ribbon supply shaft is regulated and a non-lock state where the rotation of the ribbon supply shaft is permitted in conjunction with swing actions of the partition member.
