Therefore, the hook 36c opens the path of the lock pin 34, and the lock pin 34 enters the inner surface side of the hook 36c.
When the lock pin 34 enters the inner surface side of the hook 36c, the lock lever 36 rotates clockwise in FIG. 5 by the spring force of the spring 44, and the lock lever 36 becomes the lock position (B).
Since the shaft 38 of the lock lever 36 and the lock pin 34 are on a plane perpendicular to the door 18, even if an external force acts on the door 18, the lock cannot be released.

Next, when the door 18 is opened from the closed state, the push button 30 is pushed in the state of (B). Then, the lock release lever 40 receives the force in the direction of the arrow F,
It rotates clockwise in FIG. 5 to rotate the lock lever 36 counterclockwise. Therefore, the hook 36c becomes the lock pin 34
And the lock lever 36 reaches the unlocked position as shown in (C). And the arm of the lock lever 36
The tip of 36b pushes the door 18 to open it. It is also possible to apply a force on the opening side to the door 18 by means of a spring or the like. In this way , the hook 36c becomes the lock pin 3
Opening the path of 4, the door 18 starts to open. Then, at this time, the push button 30 is changed to the magazine eject switch 4
6 is pressed to operate the magazine ejection lever 22 to start ejection of the magazine 24. After that, when the push button 30 is released, the lock lever 36 becomes the state of (A).
