Printer with multifunctional lever actuated mechanism

摘要

A printer mechanism having a receptacle for receiving a printer cartridge therein. A print head (22) is disposed in the receptacle, and a platen roller (24) is rotatable about a roller axis. The platen roller is movable between a printing position in close proximity to the print head for urging labeling media and ink ribbon toward the print head and a nonprinting position in which the roller platen is spaced a distance from said print head to allow the labeling media and ink ribbon to be slipped therebetween. A platen roller gear is coaxial with said platen roller, and is engaged with a drive gear when the platen roller is in the printing position and disengaged from the platen roller gear when the platen roller is in the nonprinting position. A lever is linked to the platen roller, and is movable between a lock position and an unlock position. Movement of the lever from the unlock position to the lock position moves the platen roller from the nonprinting position to the printing position and extends the lever over the receptacle to lock a printer cartridge received therein. <IMAGE>
