Description

[Detailed Description of the Invention] This invention relates to a back mechanism panel of a pachinko game machine, and a
Regarding the related prize ball ejecting device and its ejection control, especially when a ball hit into the game board enters the winning area?
：Bakoro'? ! : In addition to electrically detecting the winning status, the system uses a microcomputer to control the winning status, retaining the winning status, and dispensing a predetermined number of prize balls. This pachinko game machine has a structure in which the flow path is different from the conventional one, a prize ball ejecting device can be mounted by being offset to one side of the back set board, and a wide space mk is formed in the center.

As is well known, in a pachinko game machine, when a player drives balls into the game board one by one using a firing device installed at the bottom of the game board, they collide with obstacle nails and fall randomly while changing direction. A predetermined number of prize balls are given to the player by entering the winning area with a certain probability on the way to the prize. Conventionally, the payout of such prize balls has generally been carried out by using, for example, the first ball, which is attached to the back of the game board and is operated by transmitting the physical force generated by the winning ball.
This is done by a mechanical prize ball ejecting device as shown in the figure, and in conventional pachinko machines, the back mechanism is attached to the back side of the game board. A storage tank 224 for reserve balls is provided in the lower part, and a central VC connected to this part is provided with a prize ball ejection mechanism part and a prize ball collection unit 222, and a lower VC is provided with a reserve ball storage tank 224 for simultaneously stocking winning balls one by one. A controller 260 for separating and lowering the winning ball, and an operating lever 265 which is rotatable according to the weight of the separated winning ball are provided, and an interlocking rod 266 and a link mechanism 267 are connected to the end of the operating lever 265. The physical force generated by the winning ball is transmitted to the winning ball case 268VC provided at the end of the ball chute 225 through the ball chute 225. L-Activate and receive a predetermined number of prize balls? A damper 269 disposed below the damper 269
The prize balls are discharged upward, and furthermore, the prize balls are discharged into a saucer at the front by flowing downwardly through the prize ball discharge path 286.

Therefore, in conventional pachinko machines, the mechanical structure of the back mechanism panel attached to the back of the game board is complicated, making assembly and positioning adjustment troublesome, and the space occupied by the components of the back mechanism panel is large. Therefore, it is not possible to have sufficient space on the back of the game board.

In other words, there was a problem in that the space available for effective use of the back of the game board was narrowed, and maintenance and inspection of the back mechanism board became difficult.

10,000. In recent pachinko machines, a large number of prize balls called so-called lucky sevens are given out. Machines with large variable winning devices that use an electric drive source have become a target for players to join, and most VC machines are now equipped with large variable winning devices. . However.

Is the electric drive source of such a large variable prize winning device a game board? Since it is often possible to penetrate and extend to the rear of the back set board, the back mechanism board equipped with the conventional mechanical prize ball ejecting device does not have enough space to extend the entire variable prize winning device. It's inconvenient.

In addition, with the adoption of a large variable prize winning device like C, the chances of simultaneous or consecutive winning balls occurring will be extremely increased. However, in the conventional mechanical prize ball ejection mechanism, one ejection cycle takes about 1.5 seconds because the ejection operation is a mechanical link motion as described above, but with the current electric launcher, the ejection cycle takes about 1.5 seconds. The ball is fired towards the individual. That is, since a batted ball is launched into the game board every α6 seconds, a large amount of VC winning balls will be generated for a short period of time, and there is a possibility that the prize balls cannot be discharged quickly and the winning balls will accumulate one after another. Therefore, a high-speed prize ball discharging device is required, and a large amount of prize balls are paid out to the player, making it necessary to increase the size and strengthen the structure of the prize ball storage section. ing.

・Furthermore, as the speed of the prize ball ejecting device described above increases and the number of times it ejects increases, the ejecting operation is repeated frequently.
Although it is desirable to have an ejection device that can withstand this, conventional mechanical ejection devices that operate by transmitting the physical force generated by the winning balls have a limit to their ability to achieve high speeds due to friction in each mechanical part. In addition to being expensive, it also lacks durability. Moreover, is there a mechanical discharge device? Conventional pachinko machines with a conventional pachinko machine cannot operate due to abrasion or deformation of various parts, and the ball can become jammed due to foreign matter getting into the prize ball case or misalignment of the balls, resulting in poor exhaust performance. The drawback was that problems such as stoppages and ejection failures occurred, resulting in inaccurate and uncertain ejection operations. If all such weaknesses are eliminated, Vt
On the other hand, as the speed of the prize ball ejecting device increases and the number of ejected balls increases, electronic prize ball ejection control is particularly effective by detecting the ejected prize balls or the prize balls just before being ejected, and detecting the ejection state. A means to do so becomes necessary.

The present invention was made against the background as described above, and includes a control device that detects chemical bacteria on a batted ball that enters a winning area and generates an appropriate control signal based on this detection signal, and the like. By providing an electric prize ball ejector that is operated by a signal from the control device, the mechanical configuration of the back mechanism panel can be simplified, and the prize ball ejector can also be installed on the back side setting board. The purpose is to increase the effective use space of the back of the game board by mounting it so as to be offset laterally and to form a wide empty space in the center.

Another object of the present invention is to determine whether ctL is determined individually even if a ball hits a plurality of winning areas at the same time. Accurate payout is achieved by detecting, storing, and processing electronically, and by quickly detecting a shortage of prize balls and stopping operations related to prize ball ejection, unfairness to players is not caused. Our goal is to provide pachinko gaming machines such as:

Another object of the present invention is that when a large number of winning balls are generated in a short time using the motorized VC for discharging and loading prize balls, the prize balls can be paid out quickly and smoothly in response to the nvc. The object of the present invention is to improve the durability of the ejection device.

Furthermore, the present invention provides a means for detecting the ejected prize ball or the previous ejected prize ball in the prize ball ejecting device to detect the ejecting state, and based on the output from the ejecting state detecting means. Will the prize balls reach a predetermined number by a control device such as a microcombiner? Is it detected and the ejection end signal sound is emitted and ejected? The purpose of this is to prevent malfunctions such as idling of the prize ball ejecting device or prematurely ejecting the prize balls, and to enable more accurate and reliable payout of prize balls. do.

The above as well as other objects and novel features of the present invention are.

It will become clear from the description herein and the accompanying drawings.

and 25c, the prize balls lined up are alternately increased and discharged into the discharge gutter 44.

1- An L-shaped notch is formed in the blocking plate 48, and as shown in FIG. ing. 45& and 4 of the above sensors 45a to 45d
5b detects whether or not there is a ball to be ejected next in the exit portions 25- and 26c, and sensors 45c and 45d are used to confirm whether or not the ball has been ejected. The chair can also be constructed using an optical sensor or a proximity switch.

The prize ball ejecting device 40 outputs an output from the entered prize ball detector 515 n7? : When the winning detection signal is supplied to the control device 50, the motor 41 is driven by the drive signal outputted from the control device 50 and starts discharging the prize n1. At this time, based on the detection signal from the control device 5 (lj) and the discharged ball detector 45, it is confirmed that the spare balls are present at the exit of the taxiway 25, and then discharge is started. A discharge confirmation signal is output for each prize ball to 21-1 to detect the discharge state.
Have you reached a predetermined number of prize balls? It is determined and outputs an ejection end signal sound to the prize ball ejecting device 40, and the rotation of the motor 41 is stopped.

The 11th N is a prize ball ejecting device 40 controlled by the control device 50.
FIG. 2 is a block diagram showing an example of a zero control system.

Generated from the winning ball detector 55 corresponding to each winning ball.
The winning detection signal (pulse) is supplied to a memory circuit 51 as a storage means such as a counter, and is counted to store the number of winning balls. In addition, a control circuit 52 consisting of a microcomputer (CPU), etc.
b When the detection signal from the ejected ball detector 45 in the prize ball ejecting device 40 is input, and the value stored in the memory circuit 51 becomes @1# or more, the motor 41 of the prize ball ejecting device 40
Outputs a drive start signal for driving. Then, the motor 41 rotates and starts discharging the prize balls, and a detection signal (pulse) is sent from the detector 45 to the control circuit 52 for each prize ball. The control circuit 5222- counts this detection signal using an internal counter, for example.
When the count value reaches a value preset in the internal setting device, it is determined that a predetermined number of prize balls have been ejected, and a motor drive stop signal r is output, or a motor drive signal is output. Stop and finish the discharge.

In addition, if the detector 45Vc detects that there are no balls to be ejected at the exit section 25ct @ 25e2 at the end of the guideway 2F due to ball clogging during ejection, the control circuit 52 immediately stops the motor 4, holds the value r of the counter to 1, and when a prize ball enters the exit part 25c1v 25e2 rcJj, operates the motor 41 again to discharge the remaining prize balls. - When the ejection is completed, the control circuit 52i sends a signal to the memory circuit 51 to determine the memory contents. Decrement/to (decrease).

The control circuit 52 is configured to receive a signal from the ball shortage detector 56, so that even when there are no spare balls in the reserve storage section 24 and a detection signal is sent to the control circuit 52, the motor is activated. 41 drive? Alternatively, the ejection of the prize balls may be stopped.

In this case, even if the ejection of prize balls is stopped, the number of winning balls is retained in the memory circuit 51, and if there is a new winning during that time, it is detected, counted up, and stored. and,
Once the spare balls have been replenished into the spare storage section 24, it is preferable to start emitting the prize ball ejection sound again in response to a control signal from the control circuit 52.

In part, the control circuit 52 monitors all abnormalities in the ball and downward flow based on signals from a downward flow abnormality detector 57 installed in the middle of the guideway 25, where dust and foreign objects are likely to enter and cause blockages. If an abnormality signal is received during the operation, the discharge device 40 will not be operated at all. The downflow abnormality detectors 57 are arranged in two rows in the guideway 25, and are provided for each row of balls flowing down.

Furthermore, in this embodiment, a detection signal outputted from an out ball detector 71 provided in the middle of the out ball trough 23 is input to the control circuit 52 as shown in No. 4N. The control circuit 52 receives a signal from the number-of-balls setter 72, and determines the number of prize balls and out balls based on the input/award detection signal or the ejection detection signal and the out ball detection signal. Calculate the difference between the numbers and monitor the entire profit and loss situation.
When n reaches the number of stops set in advance by the setter 72, a stop signal is generated. For example, the electric batted ball launching device 10 is stopped by this batting stop signal. In addition, in this case.

A display device 73 for displaying the above-mentioned profit and loss status may be provided on the front surface of the game board, and may be displayed in digital numbers according to a signal from the control circuit 52.

(9) In the above embodiment, by changing the setting value of the setting device in the control circuit 52, it is possible to make an arbitrary number of prize balls payout at one time.

Moreover, the setting device in the control circuit 52 of the above embodiment? In addition to providing multiple settings with different setting values, the winning area 1
Nine prize detectors are installed every 5 to 18, and the type of prize? It is also possible to distinguish them and store them in the memory circuit 51, so that the number of prize balls to be ejected can be changed depending on the type of winning.

Further, as in the embodiment, a prize ball discharging device [40 is replaced with a solenoid and a flow prevention member 4] in which the separating sprocket 42 is driven by the motor 41 to separate and discharge the prize balls. It is also possible to use a device configured to separate and eject prize balls one by one.

Further, the control circuit 52 and the memory circuit 51 are backed up by a battery in order to detect a power outage and retain the information on the number of winning balls in the memory circuit 51 so that it will not be lost. .

Next, another embodiment of the present invention will be described.

In this embodiment, instead of the memory circuit 51 that electrically stores the number of winning balls upon receiving the winning detection signal, simultaneous or consecutive winning balls are physically stocked and separated one by one for each prize ball ejection operation. A winning ball separator 60 is provided in a part of the winning ball discharge path 22.

The winning ball separator 60 is constructed as shown in FIG. 12, for example. That is, the winning ball ejection path 22 is once bent sideways at the entrance to form an opening 22a, and a movable piece 61 is rotatably provided at the bottom of this opening 'Rffi22m. A micro switch 55 for detecting winning balls is disposed below this movable piece 61. Further below, a micro switch 55 is rotatably mounted by a pin 62.
A separate operating rod 68 is provided. The tip of this operating rod 68 is bent upward to form a bent piece Q3a that can protrude into the award ball ejection path 22 from the opening at the tip of the movable piece 61. Busy blocking pieces 63b are formed at positions spaced apart by n.

The separation actuation rod 68 is rotated by a solenoid 64 disposed below it, so as to separate the winning balls one by one. Before the winning ball enters the ejection path 22, the operating rod 68 rotates upward and the bent piece 68m at the tip protrudes into the ejection path 22. Therefore, as shown in FIG. 12 (1), the winning balls that are simultaneously or consecutively come into contact with the bending piece 69 and are lined up in a line, and the movable piece 61 is rotated downward by the weight of the first winning ball. The microswitch 55 is turned on.

Then, the prize ball ejecting device 40 is driven, and the solenoid 64 is energized to rotate the operating rod 63 downward, and the first winning ball is ejected into the ejection path 2 as shown in FIG. 12 (2).
At the same time, the subsequent winning balls are prevented from flowing down by the blocking piece ft8b. When the prize ball ejection completion signal is output, the current to the solenoid 64 is cut off, and the operating rod 68 is rotated upward by the repulsive force of the spring 64m. Then, the blocking piece 63b is disengaged and the next winning ball moves onto the movable piece 61, turning on the microswitch Fr5vl.

In this way, the prize balls are separated one by one in the winning ball separator 60, a detection signal is output for each winning ball, and the prize balls are discharged.

FIG. 18 is a block diagram showing an example of an electrical control system for the prize ball discharge device 40 and the prize ball separator 60.

A winning detection signal (pulse) generated from the winning ball detector (microswitch) 55 for each winning ball is supplied to the control circuit 52. A drive signal is generated based on this winning detection signal to drive the motor 4 in the prize ball ejecting device i40.
1, the discharge starts. However, at this time, if there is no spare ball in the guideway 25, a drive signal will not be generated even if the winning detection signal comes in, and the motor 41 and the solenoid 64 in the winning separator 60 will not be driven. You can also.

When the motor 41 is driven and ejection starts, the ejected ball detector 45 outputs a pulse signal for each prize ball, which is supplied to the control circuit 52 and counted by an internal counter. Ru. The count value of the counter is compared with the set value of the internal setter. The number of prize balls to be paid out for each nine winning balls is set in the setting device, and when the count value of the counter matches the set value, a discharge end signal is output from the control circuit 52. In response to this end signal, the motor 41 of the prize ball ejecting device is stopped, and the solenoid 64 of the trap and winning ball separator 60 is demagnetized.

29- Therefore, when the number of ejected balls reaches a predetermined number, the ejection of the prize balls is finished, and the subsequent winning balls are separated and detected in the n1 prize ball separator 60, and the above operation is repeated again to obtain the predetermined number of prize balls. is discharged.

As explained above, in this invention button, the prize ball ejecting device and its ejection control related to the back mechanism panel t'L of a pachinko game machine can be changed from the conventional purely mechanical system using the winning balls themselves. This is an electric prize ball discharging device that processes the balls electronically and uses a motor as a driving means to make it compact and capable of high-speed ejection. Since it is functionally and effectively arranged on the set board, it is possible to create a wide space in the center, which is a variety of new effects that have never existed before. It is possible to provide a pachinko game machine that plays the game.

For example, the prize ball ejection mechanism in conventional pachinko machines has fewer parts than the prize ball ejection mechanism. The whole thing? In addition to being able to have a compact configuration, this also simplifies the configuration of the back mechanism panel and facilitates assembly, positioning adjustment, etc. In addition, the prize ball ejector 30 is installed so that it is offset to one side of the set board on the entire back side of the device.
A preliminary storage section for prize balls is provided above the prize ball ejecting device, and a guide path is provided to automatically rectify and guide the spare balls in the preliminary storage section. connected to the inlet of the prize ball ejecting device whose downstream end is deflected above, and the ejecting location of the prize ball ejecting device is communicated with a saucer storage section provided below the prize ball ejecting device; By providing an auxiliary storage portion r communicating with the auxiliary tray in the saucer storage portion, a wide empty space 1 can be formed in the center of the back setting board.

As a result, maintenance and inspection of the back set board becomes easier, and this empty space can be used to create variable winning devices and displays, such as those that protrude from the center of the game board toward the back set board. Equipment can be attached.

In conventional pachinko machines, is there enough empty space in the center of the back set board? Since it cannot be formed, the size of the variable prize winning device required to be attached to the game board was approximately 1 cm.However, according to the present invention, it is possible to attach a large variable winning device to the game board. A highly interesting variable prize winning device that can fully satisfy all customers? Can you add entertainment value to pachinko machines? High product value? It becomes possible to do the same as above.

Is it a back set edition? , the polymerization of the first and second spaces, as a laminated structure, the same as the strength? At the same time, by widening the effective space, it becomes possible to increase the size of the tray storage section and the auxiliary storage section to accommodate the generation of a large amount of winning balls due to the adoption of a large variable winning device.

Furthermore, in this invention, winning balls are individually detected and processed electronically by a microcomputer control system, so even if multiple winning balls occur at the same time, prize balls may be ejected due to jamming. Not only does the function not stop, accurate payout is performed, and the lack of prize balls can be detected with certainty and discharging can be stopped, so there is no unfair result for the players.

f. Since we use an electric prize ball ejecting device, it is more durable and can eject at higher speeds than mechanical ones, and can quickly and quickly respond to a large number of winning balls in succession. Smooth withdrawal? I can do it.

Moreover, in this invention, the prize ball ejecting device ejects a
A prize ball that has been dropped or a prize ball that is about to be ejected? A means for detecting the discharge state is provided, and based on the output from the discharge state detection means, a control device such as a CPU determines whether a predetermined number of balls have been discharged, and a discharge end signal is generated to discharge the bulbs. If an abnormality occurs, such as a lack of spare balls or a ball clogging due to foreign matter being mixed in,

This has the effect of stopping operations related to the ejection of prize balls and preventing empty ejection or half-hearted ejection of prize balls.
