[0017]

An embodiment of the present invention will be described below with reference to the drawings. The prize-winning device 1 has a mounting board 2 to be mounted on a game board (not shown) as shown in FIGS. 1 and 2, an opening 3 is opened in the upper half of the front surface of the mounting board 2, and 3 in the lower half. A display unit 4 for digitally displaying digit numbers is provided. Further, the lower end of each of the front sides of the opening 3 is supported by supporting shafts 5 and 5, respectively, and the opening and closing operation is performed in a fan shape with the supporting shaft 5 as a fulcrum, so that it is difficult to hit a ball into the opening 3. A pair of ball receiving members 6 are provided to convert between a state and a state where a hit ball is easy to fly.

The supporting shafts 5 and 5 of the ball receiving members 6 and 6 extend horizontally and parallel to the rear, respectively, and are pivotally supported by the mounting board 2 and the mounting plate 7 at an intermediate position. From the rear. In addition, fan-shaped pinion gears 8, 8 whose teeth 8a, 8a face inward are attached to both rear ends. Between the pinion gears 8, rack gears 9, 9 meshing with the respective pinion gears 8, 8 are engraved on both sides, and a movable plate 10 that moves up and down along the mounting plate 7 is arranged.
An engagement comprising a vertically long elongated hole 11a having a constant width in the center of the upper half of the movable plate 10 and a semicircular hole 11b formed on one side of the elongated hole 11a and connected to the elongated hole 11a to form an upper edge in an arc shape. Hole 11
Is pierced. In the four corners of the movable plate 10, vertically long guide holes 12, 12, 12, 12 are penetrated, and the guide pins 13, 13, 13, 13 protruding from the mounting plate 7 are fitted.

On the other hand, a motor 15 is fixed to a cover plate 14 which is assembled so as to cover the movable plate 10 from behind, and a cam piece 17 is attached to the tip of a drive shaft 16 of the motor 15. The cam piece 17 is opposed to the engagement hole 11 of the movable plate 10, and a pin 18 facing the inside of the engagement hole 11 is located near one side of the front surface.
Protruding.

The prize winning device 1 has a well-known structure. During a game, when a hit ball enters a specific prize port (not shown) of the game board, the number on the display section 4 changes, and the specific same number is displayed. When, for example, "777" is displayed, the motor 15 is driven to rotate the cam piece 17 and to move the pin 18 in sliding contact with the inner peripheral surface of the engagement hole 11 as shown in FIG. The plate 10 is moved up and down. Along with this operation, the ball receiving members 6, 6 are continuously opened and closed via the pinion gears 8, 8 and the rack gears 9, 9 meshing with each other, and many hit balls are guided into the opening.

Thus, the present invention is directed to a narrow edge frame 1 along the arc-shaped upper edge of the engaging hole 11, more specifically, the semicircular hole 11b.
9 is provided with a notch 20 connected to the long hole 11a. As a result, for example, the movable plate 10 is displaced due to assembling, and the engagement between the rack gear 9 and the pinion gear 8 becomes irregular. In particular, when the movable plate 10 is raised, the arc-shaped inner peripheral surface of the engagement hole 11 is removed. Even if an excessive load is applied to the pin 18 that slides and pushes, the edge frame portion 19 elastically prevents the pin 18 from biting, so that the pin 1
The rotation of the motor 8 is smooth without any hindrance, and no extra load is applied to the motor 15. The notch 20 is provided at the upper edge because the load is most applied to the pin 18 when the movable plate 10 is pushed up by adjusting the own weight of the movable plate 10.

FIGS. 4 and 5 show another embodiment. FIG. 4 shows an arc-shaped opening extending along the outer peripheral edge of a cam piece 17a, leaving an edge frame portion 19a projecting a pin 18. Notch 2
FIG. 5 shows a configuration in which a long slit-shaped notch portion 20b is provided along the outer peripheral edge of the cam piece 17b, leaving an edge frame portion 19a at the tip of which a pin 18 protrudes. In this case, the movement of the movable plate 10 becomes irregular in the same manner as described above, and even if an excessive load is applied to the pin 18 that slides on the arcuate inner peripheral surface and pushes it, the pin 18 of the cam pieces 17a and 17b The integral frame portions 19a and 19b are flexible pins 1
8 can be avoided.

The present invention also provides a support shaft 5 for the ball receiving members 6,6.
5 The pinion gears 8, 8 attached to the rear end and moving the movable plate 10 up and down, and the movable plate 10 are also applicable. That is, as shown in FIG. 6, the support shafts 5, 5 of the pinion gears 8, 8 are used.
Is provided with a notch 20c having an arcuate tear, leaving the tooth portion 8a. Alternatively, as shown in FIG.
0, toothed parts 22 are provided inside the rack gears 9, 9 located on both sides of
And a groove-shaped notch 20d is formed along the rack gear 9. According to these constructions, when the rack gears 9, 9 and the pinion gears 8, 8 are displaced from each other, the meshing of the two teeth 8a, 22 is poor, and the operation of the movable plate 10 when moving up and down is not performed. As a rule, since the tooth portions 22 of the rack gears 9 and 9 or the tooth portions 8a of the pinion gears 8 and 8 are deflected, extra force escapes. Can always be performed regularly.

In the above, the driving force transmitting mechanism for operating the ball receiving members 6, 6 disposed on the front surface of the winning device 1 has been mainly described. Next, the driving force transmitting mechanism for operating the decorative member 23 will be described. . As shown in FIG. 8, a plurality of decorative members 23 are usually pivotally mounted on the front or inside of the winning device 1 and have a function of amplifying the interest of the game exclusively, without being directly related to the winning of the hit ball. .

Among them, as shown in FIG. 9, the support shafts 24 of the decorative members 23a, 23a arranged on the left and right inside the opening 3 are provided.
The gears 26 extend rearward and are supported by a mounting plate 25, and mesh with the rear ends of the support shafts 24.
Attach. Further, a small gear 27 is provided integrally with one of the gears 26. On the other hand, a motor 29 is fixed to a cover plate 28 that covers the gears 26 from behind, and a driving gear 31 attached to the tip of a driving shaft 30 meshes with the small gear 27. , 26 are rotated to operate the decorative members 23a, 23a. The opening 3
The decorative member 23b located at the upper part of the front surface of the
Is extended rearward, and a locking member 33 having a projection 32 provided at a rear end is attached thereto. A projection 34 is also provided on the other gear 26, and locking holes 35, 35 formed at both ends are respectively formed. The link 36 is connected between the both support shafts 24, 24a by fitting to the protrusions 32, 34. Then, with the rotation of the gear 26, the link 3
The decorative member 23b is interlocked via 6.

Therefore, the present invention relates to the two gears 2 meshing with each other.
6, 26 between the shaft portion 26a and the outer peripheral tooth portion 26b.
A plurality of cutouts 20e are provided, excluding a plurality of ribs 37 extending radially outward from a. Accordingly, even if a situation occurs in which the teeth 26b, 26b of the two gears 26, 26 do not mesh well with each other and cannot rotate, the extra force escapes due to the bending of the teeth 26b at the meshing portion. Therefore, the rotation of both gears 26, 26 can be performed smoothly. FIG. 10 shows another embodiment, in which the ribs 37, 37 of the gears 26, 26 are formed in a curved shape.
6b is easy to bend no matter where it is bitten, and a smooth turning operation can be performed more reliably.

FIG. 11 shows the support shaft 2 of the gears 26, 26.
A cutout 20f is provided around each shaft support of the mounting plate 25 on which the shafts 4, 24 are supported, leaving two bearing ribs 38, 38 extending outward from each shaft support. Gear 2
6 and 26, instead of hollowing out the notch 20e, the mounting plate 25 is hollowed out.
In the case where the engagement between the bearing ribs 6 and 26 is poor, the double bearing ribs 38 and 3
Since the shaft 8 is bent and the two shaft supporting portions are spread in opposite directions on both sides, the two gears 26, 26 are no longer caught and can be smoothly rotated.

Finally, the link 36 connecting the support shaft 24 on the drive side of the decorative member 23a and the rear end of the support shaft 24a on the driven side of the decorative member 23b is bent in a dogleg shape. Indicates that the hitting ball hits the decorative member 23b and the support shaft 24a
Therefore, even if some resistance occurs and the rotation becomes irregular, the link 36 bends and the gear 26 on the driving side can be continuously rotated without any trouble.

As described above, the winning device of the pachinko machine according to the present invention comprises the ball receiving member 6 and the movable plate 1 for operating the decorative member 23 disposed on both sides or inside the opening 3 of the mounting board 2.
A portion having elasticity is formed in a so-called driving force transmission mechanism such as a pinion gear 8 attached to the support shaft 5 of the ball receiving member 6 and the cam piece 17 or the rack gear 9 of the movable plate 10. The force transmitting mechanism is operated smoothly so that each ball receiving member 6 and the decorative member 23 operate regularly. Further, the above configuration is merely an example, and the movable plate 10
Thus, the decorative member 23 can be used as a mechanism for operating the ball receiving member 6 with the gears 26, 26, and, of course, a combination of the components may be used.
