  The conveyor belt 227 includes a plurality of tongue pieces 229 formed on the outer peripheral surface as strips having a length in a direction perpendicular to the moving direction. The tongue pieces 229 are fed into the conveyance path 247. The bullet is sent forward.

  Further, the bottom portion of the magazine 221 extends from the front end of the conveyance path 247 formed between the conveyance belt 227 spanned between the driving pulley 223 and the extension pulley 225 and the outer wall 231 of the magazine 221, toward the loading port 157 of the barrel 150. An introductory path 249 is formed by a concave groove inclined to enable the bullets conveyed by the conveying belt 227 from the conveying path 247 to be loaded into a loading port 157 provided on the side of the gun barrel 150, and above the introducing path 249, A stopper 235 formed of an elastic member is provided.

  As shown in FIG. 8, the stopper 235 has two leg portions 237 extending downward from both ends of one side of the flat plate-like main body, and is sent to the introduction path 249 inside the ends of the both leg portions 237. The upper side of both sides of the bullet is pressed in the immediate vicinity of the loading port 157, and the bullet passing through the introduction path 249 descending from the transport path 247 toward the loading port 157 is pressed from above.

  Therefore, the stopper 235 aligns the bullets pushed out from the conveying path 247 by the tongue piece 229 of the conveying belt 227 in a line in the introduction path 249, and also in the introduction path 249 than the leg portion 237 of the stopper 235. When there is a space on the 157 side, the bullets 229 are pushed one by one through the middle lower part of the legs 237, and one bullet is placed from the aligned bullets. It smoothly feeds to the loading port 157 formed on the upper side of the gun barrel 150.

  Then, the inside of the magazine 221 has an inclined portion 245, and as shown in FIG. 9, a supply port 243 having a cylindrical supply tube 241 at the top of the magazine 221 and having the upper end of the supply tube 241 opened, The bullets housed in the supply cylinder 241 are sent in the direction of the drive pulley 223 and the conveyor belt 227 by the inclined portion 245, and consequently, the bullets are fed into the conveyor path 247.

  As shown in FIGS. 2 and 3, the turret part 140 is suspended from a top plate 143 of the turret part 140 with a protective cylinder 147 having an inner diameter larger than the supply cylinder 241 of the magazine 221, and Even if the magazine 221 and the supply cylinder 241 are allowed to move in accordance with the movement, even if a bullet inside the supply cylinder 241 spills from the supply cylinder 241 when the bullet firing traveling toy 100 is traveling, the supply cylinder 241 is provided by the protection cylinder 147. The bullet is not scattered inside the turret part 140 by being returned to the inside of the turret 140, and a cover plate 145 simulating a tank hatch is provided at the upper end of the protective cylinder 147.

  Therefore, this bullet firing traveling toy 100 drives the traveling toy 100 by driving and controlling the traveling drive device 121 by the control unit 116, and drives and controls the turret turning device 131 to turn the turret, By driving and controlling the gun barrel 150 up and down, the firing drive mechanism 201 can be driven and controlled to fire a bullet.

  In other words, this traveling toy 100 is a traveling toy 100 equipped with a barrel 150 and a bullet launching mechanism 171, and includes a conveyance path 247 that feeds bullets into the bullet loading slot 157, a bullet supply unit, and a stopper 235 as a bullet supply mechanism. The magazine 221 has a conveyance path 247 in which a plurality of bullets are arranged between the conveyance belt 227 and the outer wall 231 of the magazine 221, and the interior space of the magazine 221 and the supply cylinder 241 are provided behind the conveyance path 247. It has a bullet supply unit, and is provided with a stopper 235 as a mechanism for sending bullets pushed out from the conveying path 247 by the conveying belt 227 one by one to the loading port 157 in the introduction path 249 closest to the loading port 157.

  The operation of the traveling toy 100 when firing a bullet is as follows. When a firing control signal is input from the control unit 116 to the firing drive mechanism 201, the bullet firing motor rotates to rotate the camshaft 207 once, that is, a cylinder. The cam 211, the piston cam 215, and the drive pulley 223 are rotated once.

  As the drive pulley 223 rotates, the transport belt 227 rotates, and bullets can be sent to the transport path 247 and the bullets on the transport path 247 can be moved to the introduction path 249 as shown in FIG.

  In addition, when the bullet loading cylinder 185 of the cylinder 183 is blocking the loading port 157 provided on the side of the barrel 150, the bullet located in the transport path 247 is pushed by the tongue piece 229 and tries to move forward. However, since the width and height of the transport path 247 are substantially equal to or slightly larger than the diameter of the bullets, the bullets of the transport path 247 are aligned in a row and sent to the introduction path 249 inclined downward. The bullets are also pressed upward by the stopper 235 to form a line, and the bullets in the transport path 247 and the introduction path 249 are pressed against the outer peripheral surface of the bullet loading cylinder 185 by the loading port 157.

  Then, when the piston cam 215 and the cylinder cam 211 rotate together with the drive pulley 223, the piston drive tooth portion 217 of the piston cam 215 meshes with the tooth portion of the drive rack 177 of the piston 175 as shown in FIG. The rack 177 can be retracted, and thus the piston 175 can be retracted. At the same time, the cylinder driving projection 213 of the cylinder cam 211 is engaged with the engagement projection 187 of the cylinder 183 so that the engagement projection 187 is retracted. Will be retreated.

  Then, by retracting the cylinder 183, the tip of the loading cylinder is retracted to the vicinity of the rear end of the loading chamber 155 to open the loading port 157, and the cylinder 183 is temporarily stopped at the retracted position by the outer periphery of the cylinder driving projection 213 to introduce the introduction path. One of the bullets pressed on the outer peripheral surface of the bullet loading cylinder 185 at 249 is loaded into the loading chamber 155.

  When the rotation of the piston cam 215 and the cylinder cam 211 further continues, the cylinder drive projection 213 of the cylinder cam 211 and the engagement projection 187 of the cylinder 183 are disengaged as shown in FIG. As a result, the cylinder 183 moves forward, and one bullet sent into the barrel 150 is fixed by pressing it against an elastic ring 159 provided at the front end position of the loading chamber 155, and the loading port 157 is closed by the bullet loading cylinder 185. To do.

  At this time, the piston drive tooth portion 217 of the piston cam 215 is kept engaged with the tooth portion of the drive rack 177 of the piston 175, and the piston 175 continues to move backward by the rotation of the piston cam 215.

  The rotation of the drive pulley 223 also continues, and the bullet in the magazine 221 and the bullet in the supply cylinder 241 are sent to the conveyance path 247 by the rotation of the conveyance belt 227, and the bullet in the conveyance path 247 and the bullet in the introduction path 249 are also sent. Are brought into close contact with each other in an aligned state and pressed against the outer surface of the bullet loading cylinder 185.

  Then, when the camshaft 207 rotates more than a half turn, the piston drive tooth portion 217 and the drive rack 177 are disengaged, and the piston 175 is biased forward by the elastic force of the piston spring 179 as shown in FIG. Therefore, the piston spring 179 is suddenly pushed forward by the elastic force, and the bullet loaded in the loading chamber 155 can be fired by air pressure.

  In the next firing, the bullets closely aligned with the conveyance path 247 and the introduction path 249 are pressed by the tongue piece portion 229 of the conveyance belt 227, and when the bullet loading cylinder 185 is retracted, the leg portion of the stopper 235 By repeating 237, one bullet is passed through the middle lower part of the leg portion 237, and the loading of the bullet into the loading chamber 155 is repeated.

  As described above, in this embodiment, when the bullet firing mechanism 171 and the firing drive mechanism 201 are driven to fire bullets such as BB bullets, the conveyor belt 227 incorporated in the magazine 221 capable of storing a plurality of bullets. Is driven to move the plurality of bullets aligned in the transport path 247 in the magazine 221 in the direction of the loading port 157 of the gun barrel 150, and by moving the piston 175 and the cylinder 183 backward, one of the bullets is loaded into the loading chamber 155. Even when the bullet firing traveling toy 100 travels on an inclined ground and the magazine 221 in the turret part 140 is inclined in various directions, a plurality of the fired toys 100 are aligned with the transport path 247 and the introduction path 249. The foremost one of the bullets can be reliably fed into the barrel 150.
