The lock pin 22 is the control slot 14 shown in FIG.
When reaching the curved guide portion 14c, the lock member 20 is moved in the X1 direction by the X-direction component Fx of the biasing force F by the biasing member 16, and the lock pin 22 enters the locking portion 14b. That is, the lock pin 22 moves in the locking portion 14b in the X1 direction, the lock pin 21 moves in the supporting elongated hole 13 in the X1 direction, and the entire lock member 20 moves in the X1 direction. By the lock pin 22 entering the locking portion 14b,
The lock member 20 is locked so as not to return in the ejection direction (Y2 direction), and the head portions 21a and 22a of the lock pins 21 and 22 are locked by the locking portions Ma2 and Mb2 of the magazine M.
The inside of the magazine M is locked without being ejected in the magazine loading unit 10A (see FIG. 5).

While the lock member 20 moves from the posture of FIG. 3 to the posture shown in FIG. 4, the lock member 20 rotates counterclockwise about the lock pin 21 as a fulcrum, but the notch formed in the lock member 20. 20b only rotates slightly in the immediate vicinity of the lock pin 21. And the lock member 20
The circular connecting portion 36 of the lock releasing member 35 slightly rotates within the circular notch 20b formed in the above, but during this period, no force is applied to the lock releasing member 35 from the lock member 20. Therefore, while the magazine M is loaded in the state of FIG. 3 and the lock member 20 is rotated by the magazine M to the posture shown in FIG. 4, the pressing protrusion 42 provided on the switching arm 40 causes the pressing piece of the unlocking member 35 to move. The state of being in contact with 37 is maintained.

After the magazine M is loaded to the position shown in FIG. 4, the lock member 20 is moved in the X1 direction by the urging force of the urging member 16 and the lock pin 21 is moved as described above.
Moves in the support slot 13 in the X1 direction, and the lock pin 22
While moving into the locking portion 14b, the moving force of the lock member 20 in the X1 direction acts on the connecting portion 36 of the lock releasing member 35, causing the lock releasing member 35 to rotate clockwise about the support shaft 38. To be Lock release member 3 at this time
The turning force of 5 acts on the pressing protrusion 42 from the pressing piece 37,
The switching arm 40 is rotated counterclockwise.

At this time, the rack portion 4 of the switching arm 40
1 rotates the small gear 51 of the reduction gear 50 in the clockwise direction, and the large gear 52 rotates the pinion gear 72 in the counterclockwise direction. The rotation power is from the worm gear 71 to the non-energized rotor of the switching motor 70. To rotate. At this time, the transmission path of the rotational force from the rack portion 41 of the switching arm 40 to the reduction gear 50, the pinion gear 72, and the worm gear 71 functions as a speed increasing gear train, so that while the switching arm 40 rotates counterclockwise. In addition, the inertial and frictional loads of the speed increasing gear train act as rotational loads. Further, in this embodiment, the rotor of the switching motor 70 in the non-energized state also acts as a load when the switching arm 40 rotates.

Therefore, the speed increasing gear train and the switching motor 70 in the non-energized state function as load generating means and apply a load to the lock member 20. The load at this time is smaller than the biasing force that the biasing member 16 applies to the lock member 20 in the latching direction with the magazine M.
The lock member 20 surely moves in the X1 direction to move to the magazine M.
And the lock member 20 moves gently in the X1 direction. Therefore, the metal lock pins 21 and 22 move in the X1 direction in the support elongated hole 13 and the control elongated hole 14 of the metal bottom plate 11, and the impact when hitting the ends of the elongated holes 13 and 14 can be alleviated, It is possible to prevent the generation of impact noise. Further, no impact is applied to the hand pushing the magazine M, and the operation for loading the magazine M can be smoothly performed.

It is rotated counterclockwise from the state of. At this time, the pressing protrusion 42 provided on the switching arm 40 is separated from the pressing piece 37 of the lock releasing member 35, and the lock releasing member 35 is released.
Is free. Therefore, the load of the load generating means including the speed increasing gear train and the switching motor 70 does not act on the unlocking member 35 and the lock member 20, and the biasing force of the biasing member 16 causes the lock member 20 to move to X1.
The magazine M is strongly attracted in the direction, and the lock pins 21 and 22 firmly lock the magazine M, so that the magazine M is securely locked.

When the switching arm 40 further rotates counterclockwise from the state shown in FIG. 5, the connecting pin 67 is held by the holding portion 40c at the end of the elongated hole 40a formed in the switching arm 40.
