Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ball cutting device for a pachinko gaming machine.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, as this type of ball cutting device for a pachinko gaming machine, a configuration example shown in FIG. 2 is known. FIG. 1 is a perspective view showing the outline of the apparatus, in which a case 1 of a partially stepped hollow box is divided into an upper space 11 and a lower space 12 shorter than the upper space 11 by a partition plate 2 having a horizontal interior. A disc-shaped revolver 3 is rotatably provided in the upper space 11 in a horizontal plane with a shaft 4 as a center, and has a thickness almost equal to a sphere diameter. Are formed at equal intervals on a concentric circle. Further, the revolver 3 meshes with the gear 5, and the gear 5 is fixed to the rotating shaft 6 a of the stepping motor 6 mounted outside the case 1 on the lower surface of the bottom plate 111 of the upper space 11 of the case 1. . At the front edge of the two discharge ports 2a (2b) provided on the partition plate 2, the balls stored in the ball storage hole 3a of the rotating revolver 3 do not fall into the discharge port 2a, Protrusions 2c (2d) having a shape suitable for preventing the tumbling are provided. Although not shown in the lower space 12, a ball discharge detection sensor and the like are housed to control the rotation of the stepping motor 6.

Further, on the upper surface of the case 1, two introduction ports 11a and 11b which are continuous with the two ball supply paths 7a and 7b are formed, and the introduction ports 11a and 11b are provided each time the revolver 3 rotates. The position is selected so as to be accommodated inside any two sphere accommodating holes 3a located symmetrically with respect to the axis 4.

Further, the lower plate 112 of the case 1 is provided with discharge outlets 12a and 12b just below the discharge ports 2a and 2b of the partition plate 2.

The operation of the ball-slicing device having the above-described structure will be described. The lowest balls of the balls arranged in the ball supply paths 7a and 7b are stored in the ball storage holes 3a of the revolver 3, respectively. . FIG. 3 is a side sectional view of a main part showing a state in which the balls stored in the revolver storage hole 3a are discharged from one of the ball supply paths 7a (or 7b).

[0006]

[Problems to be solved by the device]

 However, the ball may become stuck in the position shown in FIG. 3 due to the rotation control of the stepping motor 6, the hole diameter of the ball storage hole 3a of the revolver, the error between the ball diameters, and other factors. There was a risk of adverse effects.

In order to solve the problems of the prior art, the present invention is a pachinko machine in which a ball is not blocked between the inner surface of the case upper plate and the projection of the partition plate discharge port. An object is to provide an excellent ball cutting device for a game machine.

[0008]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above object will be described with reference to FIG. 1 corresponding to an embodiment. Case 1 has a ball supply path 7a, which is erected on upper plate introduction ports 11a, 11b (not shown). 7b is a hopper-type ball cutting device that discharges a group of balls stored in a line in a row by a revolver 3 built in the case 1, and is in front of a ball discharge outlet 2a (2b) provided on a partition plate 2 of the case 1. It is characterized in that a guiding angle 8 directed toward a ball discharging guide 2c (2d) protruding from the edge is vertically provided on the inner surface of the upper plate of the case 1.

[0009]

[Action]

 With the above construction, in the present invention, when the revolver 3 rotates and the ball stored in the ball storage hole 3a of the revolver 3 is displaced in the direction of the arrow, its head first comes into contact with the guide angle 8. After that, it is guided by the inclined surface 8a and is discharged from the lower plate discharge port 12a of the case 1 through the discharge port 2a along the lower guide 2c to perform a proper ball cutting action.

[0010]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional side view of a main part showing a ball discharging state of a hopper type ball cutting device in a pachinko gaming machine according to the present invention, and the same parts as those in FIG. 3 (conventional device) are denoted by the same reference numerals. Similar to the conventional device (see FIG. 2), the sphere A accommodated in the sphere accommodating hole 3a of the revolver 3 is rotated through a stepping motor 6 controlled by a sphere ejection detection sensor or the like, and a predetermined amount is transmitted via a gear 5. Only the step moves in the upper space 11 in the direction of the arrow. In the state shown in FIG. 1, the sphere A is first deflected downward by the inclined surface 8a of the guide angle 8 provided on the inner surface of the case upper plate 1 and guided by the guide 2c to pass through the discharge port 2a and the lower space 12. Then, it is discharged from the discharge port 12a to a predetermined portion inside the pachinko gaming machine outside the device. In this case, the distance between the guide angle 8 and the guide 2c is set so that the ball does not enter, and therefore, unlike the conventional device, the ball is not clogged.

[0011]

[Effect of device]

 As described above, according to the present invention, since the guide angle is provided opposite to the guide, the balls stored in the revolver are guided downward by the guide angle and then guided by the guide to the discharge port. Therefore, it is possible to obtain a certainty in the ball cutting operation without causing the ball clogging. Further, it can be applied to other spherical cutting devices.
