TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball shooting device for a game machine having a ball supply mechanism that has a simple structure and a reliable ball feeding operation.
[0002]
[Prior art]
At the lower part of the front of the pachinko machine, there is provided a ball launching device for driving a ball into the upper game board, and this ball launching device rotates the ball hammer and the ball hammer. And a ball supply mechanism for supplying the ball to the ball launch position of the primary rail. That is, the ball-and-ball mechanism fires a ball supplied by the ball supply mechanism to the ball-launching position of the primary rail at a fixed timing with a ball-hammer. In addition, the ball supply mechanism supplies the ball to the ball launch position of the primary rail at a constant timing by opening and closing the supply port of the ball introduced from the upper plate by intermittent driving of the stopper.
[0003]
However, in the conventional ball shooting device, as shown in Japanese Patent Application Laid-Open No. 2001-104551, a ball supply mechanism is provided in a case, and the case is pivotally mounted on a base plate. Since it is configured separately from the ball mechanism, it causes an increase in the number of parts, an increase in the size of the entire apparatus, and a complicated ball feeding structure. Further, in this ball supply mechanism, the ball introduced from the upper plate is sent out from the front toward the board surface of the gaming machine from the front to the rear, and then the ball is slightly lowered on the primary rail to the ball launching device. Since it involves three-dimensional movement in front, rear, left and right, there is a problem that the flow path of the sphere becomes long and it takes time for the sphere to stand still. In addition, since the above-mentioned stopper does not operate by directly engaging the motor that rotates the ball hammer, the operation of the ball feeding is uncertain, and the ball flow is complicated, so that the ball may be clogged. There is a problem that the supply trouble of the ball is apt to occur and the stability of the operation of the ball hammer is lacking.

FIG. 3 shows the details of the main part of the above-described bullet shooting device. The hammer driving cam 42 is formed such that the arc-shaped peripheral edge gradually changes the distance from the rotation shaft 41, and this peripheral edge is The intermittent engagement with the roller 72 axially mounted on the tip of the arm 7 causes the ball hammer 3 that has fired the ball to retreat and rotate in preparation for launching the next ball. A semicircular ridge 43 formed eccentrically with respect to the rotating shaft 41 is provided integrally with the hammer driving cam 42 as an operating cam 44 for swinging a ball feed lever on a flat portion on the side surface of the hammer driving cam 42. Have been. The ball feed lever 6 is mounted on a support shaft 61 provided on the base plate 1, and a small spring 65 is inserted into the support shaft 61 as shown in FIG. Biased in the direction. The ball feed lever 6 is swingable in the horizontal direction to the left and right with respect to the plate surface of the base plate 1. The side intermittently engages with the operation cam 44. The ball holding portion 62 receives the ball received from the upper plate via the ball inlet 64 of the cover 60 between the forks and temporarily holds the ball on the receiving base 66.
[0012]
The mechanism of supply and launch of a sphere in the above-described bullet launch device will be described with reference to FIGS.
FIG. 3 shows a state immediately after the engagement between the hammer driving cam 42 and the arm 7 is released, and the ball hammer 3 is repelled and rotated to fire the ball. In this state, the rotation of the ball feed lever 6 in the ball payout direction is restricted by the ball feed lever swinging operation cam 44, and the ball is held downward, and the next ball is held in the ball holding portion 62. ing. As soon as the engagement between the ball feed lever 6 and the operation cam 44 is released, the bias of the small spring 65 causes the ball holding portion 62 to feed the ball as shown in FIG. Direction) to drop the ball instantly from the cradle 66 onto the primary rail 2.
[0013]
Next, as the rotation of the hammer drive cam 42 advances, as shown in FIG. 5, the operation cam 44 presses the rear end 63 of the ball feed lever 6, so that the ball feed lever 6 turns backward in the counterclockwise direction. Is done. At the same time, the hammer drive cam 42 presses the arm 7 and rotates it in the counterclockwise direction, so that the ball hammer 3 is also integrally rotated in the counterclockwise direction. Then, as shown in FIG. 6, shortly after the ball feed lever 6 is oriented substantially vertically downward and the ball is taken into the ball holding portion 62, the ball hammer 3 is soon rotated to the maximum and ready for ball firing. Complete. Next, when the engagement between the hammer driving cam 42 and the arm 7 is released, the bullet hammer 3 can fire the next ball as shown in FIG. By repeating the above operations, the ball launching apparatus can continuously launch a ball.

FIG. 7 shows a main part of the bullet shooting device of the second embodiment. In this embodiment, a protrusion 46 is formed on a flat portion on the side surface of the hammer drive cam 42 so as to be separated from the support shaft 41. On the other hand, a cut 67 is formed in the rear end 63 of the ball feed lever 6, and the projection 46 slides in the cut 67 by rotating around the support shaft 41 integrally with the hammer drive cam 42. The feed lever 6 is swung. That is, by sequentially transitioning from the state of FIG. 7 to the state of FIG. 10, the ball feed lever 6 can take out the next ball into the ball holding unit 62 after sending out the ball. The linked state of the swing of the ball feed lever 6 and the rotation of the ball hammer 3 is the same as in the first embodiment, and FIGS. 7 to 10 correspond to FIGS.
[0016]
Instead of the cam mechanism described above, the ball feed lever 6 can be swung by a link mechanism as shown in FIGS. In the figure, a hammer driving cam 42 having a shape similar to a magatama and an eccentric cam 47 integrally formed on a flat portion of the cam 42 are axially mounted on a rotating shaft 41 of the motor-4. Is coaxial with the hammer driving cam 42 and is axially mounted on the rotating shaft 41.
