Description

[Detailed Description of the Invention] The present invention relates to a winning ball device used in pinball game machines such as pachinko machines.

For example, pachinko machines are equipped with a winning ball device called a so-called yakumono, such as a chulip, in order to enhance the player's interest when a winning ball is won. Among these winning ball devices, in recent years players have become familiar with slot machines in which symbols are arranged on the reels and rewards are given according to the symbols that appear in the display window when the reels stop. ing.

However, conventional winning ball devices that apply such slot machines are, for example,
As known from Japanese Patent Publication No. 41272 and Japanese Unexamined Patent Publication No. 58-58076, the reel is rotated by a motor,
Furthermore, when stopping rotation, a stopper operated by electrical control is used, and a stop control circuit is used in addition to the motor drive circuit, which complicates the configuration and is disadvantageous in terms of cost. Another drawback is that a large space is required for installing electrical components such as the drive control circuit.

The present invention was made in view of the problems of the conventional device as described above, and the winning ball device has a simplified mechanism by mechanically rotating the reel by using the weight of the winning ball. The purpose is to provide For this reason, in the device of the present invention, the reel is rotated by utilizing the engagement and feeding action between the feed pawl provided on the swing lever that swings due to the weight of the winning ball and the feed gear that is coaxial with the reel. This is what I did.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram showing an example of the front panel configuration of a pachinko machine using the device of the present invention. In FIG. 1, reference numeral 10 denotes a winning ball device. When a pachinko ball enters from above, it is activated as will be described later. Depending on the result of the activation, prizes are given, such as opening all of the ticket 3 or opening the attacker 5 for a predetermined period of time. It will be opened.

FIG. 2 is a front view of the winning ball device 10 shown in FIG. 1. The front decorative board 12 of the winning ball device 10 has guide arms (tulip pieces) 13a, 13b.
are pivotally attached around shafts 14a, 14b, and initially a pair of guide arms 13a, 1
3b both stand up vertically and narrow the safe hole area, making it difficult for the ball to enter. next,
When a winning ball enters between the guide arms 13 and 13b, it is distributed to the left and right by the fixed guide piece 15,
Push one of the guide arms, for example 13b, to open it as shown by the two-dot chain line. Here, the guide arms 13b and 13a are interlocked by a rack gear mechanism (not shown), so when one guide arm 13b is pushed open by a winning ball, the other guide arm 13a also opens at the same time (the second guide arm 13a opens). (See Figure 1). As a result, the pair of guide arms 13a and 13b swing in opposite directions, widening the safe hole area and making it easier for the ball to enter. After this, the ball moves again to the guide arm 13.
When it enters between a and 13b, it pushes away the lower end of guide arm 13a or 13b and flows down, so that both of the open pair of guide arms 13a and 13b return to their vertical positions.

20a, 20b, and 20c are reels with numbers arranged on their peripheries, and when a winning ball enters any of the winning ball passage entrances 16a to 16c, as will be described later, the corresponding reel 2
0a to 20c are rotated by one pitch of the numerical arrangement. In addition, each reel has 20
Numbers a to 20c are display windows 21a and 21, respectively.
It is observed by the player from points b and 21c.

Windows 22a, 22b and windows 23a, 23b, 23
C is a display window with various display lamps installed behind it, and these display lamps indicate, for example, reel 2.
The rotation operation of 0a to 20c is displayed, or the case where a privilege is given by this winning ball device is displayed. Note that the reference numeral 24 is a normal safe hole.

3 and 4 are side sectional views and perspective views, respectively, of the main parts of the winning ball device shown in FIG. 2, that is, the mechanism for rotating the reels by winning balls. As shown in Fig. 2, three reels are arranged side by side and each has its own rotating mechanism, but since they all have the same structure, only one of them is shown in Figs. 3 and 4. . In the figure, winning ball passage entrance 1
The winning ball 80 that has entered the ball 6a advances through the winning ball path 25 and finally reaches the winning ball collection path 28, after which it is sent to a winning ball number counter (not shown),
Conventionally known appropriate mechanisms such as a prize ball dispensing device are provided.

The reel 20a is rotatably mounted around a shaft 30 provided near the winning ball path 25. Note that this shaft 30 is configured as a common shaft for all of the reels 20a, 20b, and 20c shown in FIG. A coaxially integrated ratchet gear 31 is provided on the reel 20a, and the reel 20a
A signal hole 32 is provided in the inner plane wall of the signal hole 32 passing through the inner plane wall. Further, an L-shaped swinging lever 35 is pivotally attached to the shaft 30, and a pin 36 facing into the winning ball passage 25 is planted at one end, and a ratchet claw is mounted at the other end. Lever 37 is shaft 3
8, it is also swingably attached.
One end of the ratchet claw lever 37 is provided with a ratchet claw 37a that engages with and sends the aforementioned ratchet gear 31, and the other end is provided with a weight 37b. A return rocking force is applied in the counterclockwise direction. Further, 39 is a weight, which is attached to the shaft 38, and this weight 39 applies a return swing force to the swing lever 35 in the clockwise direction in FIG. Reference numeral 42 designates a non-return pawl pivotally connected to another shaft 41 parallel to the shaft 30 and biased toward the ratchet gear 31 by a weight 43;
counterclockwise rotation.

A circular arc-shaped notch 46 and a recess 47 are formed in a part of the side wall of the winning ball passage 25, and serve as escape areas for the pin 36 when the swing lever 37 swings. In addition, a solenoid 52 is pivotally connected to a shaft 49 on a part of the wall forming the winning ball passage 25.
A closing plate 50 is attached which is moved from the solid line position in FIG. is taking the position of

The effects based on the above configuration are as follows.
The winning ball 80 that has entered the winning ball path 25 from the winning ball path entrance 16a pushes down the pin 36 by its own weight while falling to the winning ball recovery path 28.
As a result, the swing lever 35 is swung from the position shown in FIG. 3 to the position shown in FIG. 4. The sum of the weights of the weight 39 and the weight 37b and the length of each L-shaped arm of the swing lever 35 are designed to comply with the above-mentioned effect.

As the swinging lever 35 is swung by the weight of the winning ball 80, the ratchet pawl 37a slides on the teeth of the ratchet gear 31 and reaches the position shown in FIG. During this process, the ratchet gear 3
Since the check pawl 42 is engaged with the ratchet gear 31, the ratchet gear 31 is not rotated.

When the state shown in FIG. 4 is reached, the pin 36 planted at one end of the swing lever 35 enters the recess 47, and the winning ball 80 is sent to the winning ball recovery path 28. When the weight of the winning ball on the swinging lever 35 is released in this way, the swinging lever 35
9, it is swung from the position shown in FIG. 4 to the position shown in FIG. 3 and back. Ratchet lever 3
Reference numeral 7 indicates that the weight 37b applies a biasing force in the direction in which the ratchet pawl 37a engages with the ratchet gear 31, so that when the rocking lever 35 makes the aforementioned return rocking motion, the ratchet gear 31 is advanced by one tooth. . As a result, the reel 20a also rotates, and by arranging numbers and symbols on the periphery of the reel according to the pitch of the ratchet gear 31, the numbers and symbols change by one frame each time a winning ball passes through. become.

Three such reel rotation mechanisms such as the reel 20a and the swinging lever 35 are coaxially arranged in parallel as shown in FIG. , "7" is detected by a photo sensor (not shown) that photoelectrically detects a signal hole 32 provided at a specific position on the inner wall of each reel. That is, the detection optical axis is set parallel to the rotation center axis 30 of each reel, and a light emitting part that emits near-infrared light and a light receiving part that receives this near-infrared light are placed at positions sandwiching all the reels. If provided, a photodetection signal will be obtained only when all the reels are in the predetermined position. When this detection signal is obtained, a reward is given to the player.

As a privilege given to the player, if all of the tubes 3 shown in Figure 1 are opened by solenoids, the tubes 3 will automatically close when a safe ball is received. Therefore, the configuration described so far can be put into practical use. However, as a bonus given to players, the attacker 5 shown in Figure 1
If you want to open for a predetermined time, for example 10 seconds,
Winning ball device 1 during the time when this benefit is given
If a winning ball lands on 0, one of the reels will rotate and the pattern will change, resulting in an unnatural result. Additionally, the detection signal from the photo sensor described above will no longer be output, and depending on the circuit configuration, the benefit may be interrupted. In order to cope with such operations, a closing plate 50 shown in FIG. 3 or 5 is also used. That is, the detection signal from the photo sensor described above is obtained, and at the same time a privilege is given, the solenoid 52 is activated, the closing plate 50 is rotated clockwise around the shaft 49, and the tip of the closing plate 50 is placed in the winning ball path. Enter 25. Therefore, even if a winning ball enters the winning ball passage 25 after the award is given, its progress is blocked by the closing plate 50, the swinging lever 35 does not swing, and the reels also do not rotate. . When the aforementioned bonus time of 10 seconds has elapsed, the solenoid 52 is deenergized and the game returns to the normal game.

Although the apparatus of the present invention has been described so far based on the illustrated embodiments, the present invention is not limited thereto. For example, various configurations can be considered, such as increasing or decreasing the number of reels or changing the shape of the swinging lever, and by deforming the feed mechanism of the ratchet gear and ratchet pawl, the reel is fed when the swinging lever moves forward, and the reel is moved when the swinging lever moves backward. It is also possible to prevent rotation. Furthermore, those skilled in the art can conceive of many embodiments by applying the present invention, such as making the swing lever swing by the weight of two winning balls.

As described in detail above, the present invention is mechanically simplified and extremely cost-effective and space-efficient when configuring a winning ball device using reels in pinball game machines such as pachinko machines. can provide something advantageous. Furthermore, since the reels are rotated in sequence according to the number of winning balls, a unique and interesting game can be obtained, which is very effective.
