A portion of the case 104A protrudes from the barrel 102. The magazine 1 includes a chamber 12 which does not communicate with the storage space 11. The portion of the case 104A protruding from the barrel 102 is accommodated in the chamber 12 of the magazine 1 so as to prevent foreign objects from entering to affect the operation of the press member 104B and the passive member 104C.
The press member 104B is an inverted L-shaped member which includes a first portion and a second portion which extends from one end of the first portion. The first portion of the press member 104B is located between the block 109 and the inside of the room 106. The press member 104B includes a first notch 110 and a second notch 110A respectively facing the block 109. The block 109 includes a ball 111 which is biased by a first spring 112 which is located in the block 109. The ball 111 is selectively engaged with the first notch 110A or the second notch 110B.
The trigger 104D has the first end thereof pivotably connected in the room 106, and the second end of the trigger 14 extends beyond the second opening 108 of the case 104A. The passive member 104C is pivotably located in the room 106, and located between the press member 109 and trigger 104D.

The string 103B is then pulled in the slot 105 and toward the rear end 102B of the barrel 102. The string 103B then touches and pivots the stop 104E. After the string 103B moves over the stop 104E, the stop 104E returns to its initial position by the recovery force of the torsion spring 104F. The string 103B is restricted from shooting by the stop 104E. The lowest arrow 20 in the storage space 11 enters into the flight groove 101 of the barrel 102 because of the string 103B does not restricts the arrow 20 to be lowered. It is noted that the string 103B is restricted from shooting by the stop 104E because the hall 111 is engaged with the first notch 110, and the press member 104B and the passive member 104C contact and restrict each other. Therefore, the passive member 104C cannot pivot, and the passive member 104C restricts the stop 104E to pivot, so as to restrict the string 103B from shooting.
After the arrow 20 is located in the flight groove 101 of the barrel 102, the user push the rods 115 to move the press member 104B toward the front end 102A of the barrel 102 to remove the ball 111 from the first notch 110, and the ball 111 is shifted to be engaged with the second notch 110A.
Therefore, the press member 104B is released, and the passive member 104C is pivotable. The user then aim the target and pulls the trigger 104D which pivots the passive member 104C. The pivotal movement of the passive member 104C releases the stop 104E so that the string 103B pivots the stop 104E. The string 103B then shoots the arrow 20. By repeating the steps mentioned above, the lowest arrow 20 enters into the flight groove 101 so that the user is able to shoot continuously.
The case 104A includes a first part 116 and a second part 117 which is mounted to the first part 116 to from the room 106.
