<p>PURPOSE: A gas cartridge loading mechanism is provided to orient a gas cartridge in a desired position without manual observation. CONSTITUTION: A gas cartridge loading mechanism comprises a sensor member(102) and a stopper(34). The sensor member moves along with a gas cartridge(21) toward a collar holding unit(55) and pivots between a locking position and a release position(P7). The stopper prevents the sensor member from moving toward the collar holding unit when the sensor member is in the locking position while allowing the sensor member to move toward the collar holding unit when the sensor member is in the release position. If a collar notch of a coupling collar(22) is deviated from the set direction when arranging the gas cartridge in a setting position(P1), the sensor member is pushed by the coupling collar to be moved to the locking position and, if the collar notch is arranged in the set direction, the sensor member is engaged with the collar notch to be located in the release position.</p> |
