<p>PURPOSE:To prevent a rack and a gear from damaging by providing a stopper arm which guides a magazine, receiving the magazine once with the stopper arm when it is inserted to a cartridge loader, and after that, engaging the rack of the magazine with the gear. CONSTITUTION:A control part 11 is provided which drives the stopper arm 6 to a second position II until a second sensor 9 reacts by using a second driving part 7 when the magazine 1 is abutted with the stopper arm 6 located at a first position I and a first sensor 8 detects the magazine 1. An inserted magazine 1 is abutted with the stopper arm 6 located at the first position I once before the rack 5 is engaged with the gear 3, and the first sensor 8 detects the magazine 1. When the first sensor 8 reacts correspondingly, the control part 11 drives the stopper arm 6 via the second driving part 7, and guides the magazine 1 to the second position II, and engages the rack 5 with the gear 3. In such a way, it is possible to prevent the rack 5 and the gear 3 from damaging.</p> |
