DEVICE FOR CARTRIDGE INTERLOCKING AND RELEASE Russian patent published in 2009 - IPC B41J3/407 

FIELD: mechanics.

SUBSTANCE: invention relates to printers to print labels and, particularly deals with cartridge interlocking unit in label printer and cartridge release. Label printer contains cartridge input section having basis, upper hole being opposite to the basis, interlocking and release mechanisms, which extend from the basis. The release mechanism includes release unit having upper surface to interact with the cartridge. The release unit is movable in the first direction to side of the above mentioned basis and tends to be displaced in the second direction to the side of the above-mentioned upper hole. So the effort applied to the release unit and directed to the basis forces the release unit to move the first direction. When this effort is not available, the release unit tends to move in the second direction. The said release mechanism is installed so that when cartridge is in the input section, the release unit passes through the hole available in the cartridge bottom. It proposed by the invention to provide cartridge with labels and method of cartridge loading and unloading from printer.

EFFECT: improved mechanisms of thrust ring and propulsive plate.
