Abstract:
1. A laser printer comprising: a front side, wherein a toner cartridge is removable from the laser printer through the front side; a support frame arranged at a side of said toner cartridge; a coupling supported by said support frame, movable toward and away from said toner cartridge, and including an insert at a side thereof facing said toner cartridge; a spring biasing to force said coupling toward said toner cartridge; a coupling receding arm moving said coupling, said coupling receding arm being formed of a single member and including: wherein said coupling receding arm is adapted such that when said toner cartridge is attached, said lock lever is rotated around said arm portion's longitudinal axis and thus turned downward to contact a front surface of said toner cartridge and said engagement is set to have a longitudinal direction substantially parallel to said coupling's contact surface to allow said insert to be inserted into said toner cartridge, and wherein to remove said toner cartridge, said lock lever is rotated around said arm portion's longitudinal axis and thus raised to detach from said toner cartridge and said engagement is set to have its longitudinal direction substantially perpendicular to said coupling's contact surface to push said coupling to recede said insert from said toner cartridge.
