Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine, and more particularly to a pachinko game machine having a door with means for detecting a pachinko ball.

[0002]

2. Description of the Related Art Generally, a pachinko game machine has a board surface (base board) that forms a space for moving a pachinko ball, a glass plate that covers the pachinko ball at a constant interval, a pachinko ball, and the board surface and the glass plate. And a projection mechanism for projecting into a space partitioned by. Pachinko game machine,
The board surface is installed so that it is substantially parallel to the vertical direction. On the board surface, a plurality of winning holes will be awarded when a pachinko ball enters the board surface and is ejected from the board surface, and one exit hole from which the pachinko balls that did not enter the winning hole are finally collected and ejected from the board surface. And are provided.

In addition, a large number of pins (nails) have a length corresponding to the diameter of the pachinko ball so that the pachinko ball falling along the plate surface frequently collides with the board surface and causes fluctuations in the movement direction. It is provided substantially vertically while protruding from the board surface. These pins, while repelling or refracting the striking pachinko ball, lead to the winning hole in some cases, and in some cases, guide it away from the winning hole. Has been decided.

As shown in FIG. 2, normally, in a pachinko parlor, the pachinko game machine 10 is operated by a user 1000.
In order to make it easier to use, the two units are arranged adjacent to each other in two rows with their backs facing each other. Further, in the parlor, there are provided a group of pachinko game machines 10 arranged in this way, forming a so-called island shape. Here, in FIG. 2, the opposite pachinko game machine 1
A typical size of a distance of 0 and a gap between adjacent game machines 10 is shown.

By the way, in a pachinko parlor in which a large number of such pachinko game machines are arranged, it is necessary to manage the winning situation in each pachinko game machine. That is,
This is because it is necessary to find a machine with an uneven trajectory of a pachinko ball or a machine with an abnormal trajectory, and perform replacement or repair. For example, if a machine that is unusually easy to win is left unattended, management damage to the pachinko parlor becomes great, so it is necessary to find such a machine. Also,
On the other hand, if there is a machine that is unusually difficult to win, the parlor will be disliked by the customer, so it is necessary to find such a machine. Also, it is necessary to detect an illegal act such as guiding a pachinko ball with a magnet or the like during the execution of the game.

[0006] Conventionally, as a pachinko ball detection device for such a purpose, the applicant of the present invention has filed Japanese Patent Application No. 2-244898.
In the specification of Japanese Unexamined Patent Publication (Kokai) No. 4-122375, it has been proposed to construct a pachinko ball sensor using a transmission line and a reception line. That is, a plurality of forward and backward transmission lines are attached in parallel to one side of the glass substrate of the door of the pachinko game machine, and a plurality of forward and backward reception lines are arranged in parallel and electromagnetically coupled to the transmission line. Thus, a sensor is shown that is configured to intersect and be mounted on the opposite side of the glass substrate.

According to this sensor, the transmission circuit and the reception circuit of the management device are connected to the corresponding transmission line and the reception line, and a signal current is sequentially applied to each transmission line, and each reception line is induced by the signal current. By detecting the induced current sequentially, the presence or absence of a pachinko ball is detected from the induced current received by the receiving circuit, and the combination of the transmission line carrying the signal current and the receiving line receiving the induced current is detected. Knowing, the position of the pachinko ball can be detected.

That is, in this sensor, the intersection of the transmission line and the reception line serves as a detection unit. Then, those detection units are arranged in a matrix.

With such a sensor, the number of hit balls is counted,
That is, when counting the number of balls that are hit in the game area by the projection mechanism, pay attention to one of the detection units in the area where the ball passes and determine whether the pachinko ball has passed that detection unit. This is done by monitoring and detecting the signal when passing. The number of balls is counted by counting the detection signal with a counter.

[0010]

According to this type of detection device, the position of the pachinko ball on the board surface of the pachinko game machine,
As a result, data representing the trajectory can be easily and quickly obtained. Further, since the sensor is attached to the cover (door) of the pachinko machine, there is a special advantage that the structure can be made unrelated to the design of the pachinko machine by simply replacing the cover.

However, the pachinko balls repelled on the board surface take various routes due to the influence of obstacles such as nails, or fall up, and finally enter the out hole or the winning hole. The speed of pachinko balls during this period varies, but the upper limit reaches a considerable speed. Therefore, it has been found that it is difficult to accurately grasp the whereabouts of one pachinko ball and trace the path thereof simply by detecting the sensor output of each coordinate.

Further, the pachinko balls must be tracked in real time at high speed, and if the sensor outputs of all the coordinates are evenly checked, the processing load of the processing means is large.

A first object of the present invention is to provide a pachinko ball detecting device which can detect the whereabouts of a pachinko ball on the board with higher accuracy by using the above sensor.

A second object of the present invention is to provide a pachinko ball detecting device which can reduce the processing load of the pachinko ball tracking process.

A third object of the present invention is to provide a pachinko ball detection device capable of compensating for misses due to tracking of pachinko balls.

[0016]

In order to achieve the above object, a pachinko ball detecting device according to the present invention is arranged to face a board surface of a pachinko game machine in which a game area is set,
A sensor having a plurality of detection points arranged in a matrix, which magnetically detects pachinko balls existing on the board at regular intervals, and a sensor which periodically collects the sensor output at each detection point of the sensor. Output collecting means, a memory for storing calculation data obtained by calculating the collected sensor output for each detection point, and a ball hit on a board based on the collected sensor output. With regard to the winning-ball search means for searching the current position and the winning ball detected in the certain cycle by the above-mentioned winning-ball search means, based on the operation data stored in the memory in the next cycle, the new position of the pachinko ball is determined. To repeat the process of searching and searching for a new position based on the calculation data in the next cycle for the new position detected by the search. A tracking processing means for sequentially tracking the movement position of the incoming ball, and a capture block defining a plurality of detection point groups for capturing a pachinko ball lost during tracking on the board. Defining means, capturing block search means for determining that there is a pachinko ball at the position of the strongest reaction whose calculated data exceeds the reference value among the detection points in the capturing block, and pachinko detected by the ball input searching means. The ball is a normal ball,
And, the pachinko ball detected by the capture block search means as a captured ball, at least the current position of the pachinko ball is respectively registered, ball management table means referred to and updated by the tracking processing means, the tracking processing The means is adapted to trace the captured balls as well.

In this apparatus, preferably, for each detection point where a pachinko ball may exist on the board, a search frame defining means for defining a search frame composed of a plurality of detection points around the position is further provided, and the tracking is performed. The processing means obtains the new position by searching a detection point group in a search frame for the current position. In this case, when the search frame of the tracked pachinko ball overlaps the range of the capture block, the capture block search means omits the search for the detection point in the search frame.

The tracking processing means preferably changes the captured ball to a normal ball in the ball management table means when the captured ball can be continuously tracked a predetermined number of times.

An overlap search means for searching the position overlap between the pachinko balls registered in the ball management table based on the processing result of the tracking processing means is further provided, and before the captured ball is changed to a normal ball, When it is determined that the captured balls registered in the ball management table means overlap with the normal balls, the tracking processing means preferably deletes the captured balls from the ball management table. Further, when it is determined that the normal balls registered in the ball management table means are continuously overlapped with other normal balls for a plurality of predesignated cycles, one of the normal balls is managed as the ball management. Delete from the table.

[0020]

The function of retrieving a ball retrieves the current position of the ball deposited on the board based on the sensor output. At this time, since the pachinko balls are launched at high speed, not all balls are surely grasped as the incoming balls. Therefore, some overlooked balls occur. Further, the tracking processing means sequentially tracks the moving position of each incoming ball on the board. Missing balls may occur during this chase.

In the present invention, such a missed ball is captured by providing the capture block definition means and the capture block search means. The tracking processing means also tracks the captured pachinko balls.

However, if a ball which has already been detected as an incoming ball and is being tracked is captured, an error occurs in the number of balls. Therefore, a search frame definition unit is further provided, and the capture block search unit omits a search for a detection point in the search frame when the search frame of the tracked pachinko ball overlaps the range of the capture block. . This can reduce the possibility of further catching balls that have already been managed.

When the captured ball can be continuously tracked a predetermined number of times, the captured ball is changed to a normal ball in the ball management table means, and the captured ball is restored as a normal ball.

Since the captured ball is highly likely to be erroneously detected due to the influence of the normal ball, another condition is imposed before the captured ball is changed to the normal ball. That is, when it is determined that the captured ball registered in the ball management table means overlaps with the normal ball, the captured ball is deleted from the ball management table. On the other hand, when it is determined that the normal balls are overlapped with each other, only one of the normal balls is deleted from the ball management table only when it is determined that the normal balls are continuously overlapped with each other for a plurality of cycles specified in advance. To do. This is because the fact that it is determined that they overlap may be an erroneous determination.

Is a channel switched by the channel switching logic 43 to sequentially operate the totem pole driver 45, whereby the totem pole driver 45 sequentially outputs the signals amplified by the amplifier 42 to the transmission line 22 (step 91). .

Then, an electromotive force is generated by the electromagnetic induction action on each reception line 26 that intersects the transmission line 22 to which the signal is transmitted. At this time, when a pachinko ball that is a metal approaches the detection unit 20a, the detection unit 20a is affected by the influence.
Then, the magnitude of the electromotive force (induced current) of the reception line 26 changes.

The reason for this is not always clearly analyzed at present, but it can be considered as follows. First, pachinko balls are ferromagnetic materials because iron is the main component. Therefore, it occurs on the transmission line 22,
The magnetic flux that has spread in the space will be focused on the pachinko balls, and the distribution of the magnetic flux that links the reception lines will change. In addition, an eddy current is generated in the pachinko ball in the direction in which the magnetic flux generated by the transmission line 22 is canceled. Because of these, the induced current changes. Which is dominant depends on the relative positional relationship between the pachinko ball and the transmission line 22 and the reception line 26. Also, whether or not the magnetic flux interlinking the reception line 26 increases depends on the relative positional relationship with the pachinko ball. Furthermore, it also depends on whether or not metal is present in the background. In either case, it is sufficient that the change can be detected.

On the receiving side, the receiving circuit 50 is synchronized with the transmitting circuit 40 by the sequence control circuit 47, and each CT 51
A signal is received from each reception line 26 via. As shown in FIG. 9, the voltage due to the induced current appearing in the plurality of reception lines 26 is converted to 10 times the magnitude by the CT 51.
Since the conversion is performed by CT51, it is not necessary to increase the amplification degree of the amplifier on the receiving side. CT51
Are the receiving lines 26 and the receiving circuit 5 of the matrix sensor 20.
The analog multiplexer 52 of 0 is insulated, and noise from the pachinko game machine 10 is prevented from entering the receiving circuit 50.

The analog multiplexer 52 has a CT 51
The signal from each receiving line 26 passing through is switched by the channel switching logic 54 and sequentially output. The signal from the analog multiplexer 52 is amplified 100 times by the amplifier 53 (step 92).

The received signal is received by the receiving connector 55 and the amplifier 7.
1. Amplification and detection are performed through the bandpass filter 72. The received signal from the bandpass filter 72 is an analog signal, and this analog signal is
The full-wave rectification / amplifier 73 performs waveform shaping. The signal from the full-wave rectifier / amplifier 73 is supplied to the low-pass filter 7
Averaging is performed by integration processing at 4a and 74b.

Next, the received signal is the A / D converter 75.
Sent to The A / D converter 75 converts the signal from the receiving line 26 into a digital signal in a predetermined bit unit such as 12 bits, and outputs the converted signal (detection data) under the control of the sequence control circuit 47. Then, after the above-mentioned data conversion is performed by the data conversion circuit unit 200, it is registered in the bidirectional RAM 76 (step 93).

That is, the bidirectional RAM 76 receives the write signal from the sequence control circuit 47, and the information processing apparatus 3 receives the write signal.
After recording the detection data irrespective of the operation of 0, the address is incremented by +1 every scan cycle (for example, every 28 ms) based on the clock signal output from the sequence control circuit 47.
Up (step 94), the conversion data (calculation data) of the detection data is registered in a different address for each detection unit 20a.

The above operation is repeated every scan cycle. That is, in each scan cycle, the analog multiplexer 52 of the receiving circuit 50 switches the signal from each receiving line 26 (step 95) and performs the above operation 32 times for 32 receiving lines 26. When this is completed (step 96), at that point, the analog multiplexer 44 of the transmission circuit 40 switches the transmission line 22 (see step 97), the same processing is repeated 32 times again, and the detection units 20a are sequentially detected. The conversion data is stored in the detection unit 20 at different addresses in the bidirectional RAM 76.
It is registered in association with a.

Therefore, the information processing apparatus 30 reads out the detection data registered in the bidirectional RAM 76, so that the pachinko machine can be moved to any position (detection unit 20a) at any time, independently of the detection signal processing operation. Whether or not a ball is present can be determined at any time using arbitrary search conditions.

Therefore, the CPU 30 of the information processing device 30
a is bidirectional R by a read start signal, if necessary.
The detection data recorded in the AM76 is read into the memory 30b, arithmetic processing is performed, and the detection data is stored in the card 173.
The pachinko balls can be monitored in association with the parameter data of the pachinko balls stored in.

In this embodiment, various parameters are set in the card 1.
73. This is because when the pachinko game machine is exchanged, various aspects of the point data corresponding to the new machine are supplied by the card so that the mode can be performed quickly and easily. However, the present invention is not limited to this. Other storage media, for example,
It may be configured to be stored in the memory 30b.

Now, a method (called a locus algorithm) capable of tracking the whereabouts of a pachinko ball with higher accuracy by using the above-mentioned pachinko ball detecting device will be described in detail. This is an algorithm for tracking the trajectory of a pachinko ball using the operation data read from the bidirectional RAM 76.

According to FIG. 57, this trajectory algorithm 65
0 shows the general processing procedure. Details of various flags and processes appearing in this flow will be described later, and therefore only their names are shown here in the order of execution. The locus algorithm 650 is executed every scanning cycle of the sensor.

First, as initialization processing, the winning flag is reset (651) and the capture prohibition flag is reset (652). Next, a normal ball in-frame search process is performed (653), and then a ball entry search process is performed (654). Further, an intra-frame search process for a captured ball is performed (656), and a capture prohibition flag 272 (FIG. 35) is set (65).
7). Finally, an intra-capture block search process 658 is performed.
As will be described later, each of these processes needs to be executed within a fixed period, and when the periodicity is likely to be disturbed, the skip flag is turned on and the process is forcibly terminated even in the middle of the process. Therefore, the processing order is set so that relatively important processing is executed first and other processing is executed later.

FIG. 11 shows a means for searching for an incoming ball for first detecting the pachinko ball projected by the projection mechanism. In FIG. 11, the projected ball is the game area 12a.
Ten pay-in search points 900 are provided at the position of the guide passage of the guide rail 12 immediately before leaving. This is a setting area for relatively accurately grasping each pachinko ball that is driven at high speed. As the data to be used, raw data that is not subjected to the subtraction using the slice data and the offset data is used. This is to see how much the reaction has changed at different times. This raw data is the data as it is output from the A / D converter 75, and has a level of 0 to 255 in this embodiment. In order to use the raw data, 00H is set to the addresses corresponding to the respective entry points of the slice area in the memory (30b) for storing the slice data and the offset area for storing the offset data. deep. Note that 32 × 32 (= 10
24) An address (capacity) for points is secured.

FIG. 12 shows the software configuration of the pay-in search processing. This process is executed by the incoming coin search unit 901 every scan cycle (here, 28 ms). The input to the pay-in search unit 901 is read data 760 from the bidirectional RAM 76, and a pay-in search point table 130 described later.
And the data of the fixed search frame type designation table 220, the count value of the incoming ball weight counter 134, and the previous value 138 of the incoming point point raw data storage area. The data of the pay-in search point table 130 and the fixed search frame type designation table 220 are given from the card 173. The value of the number of ball insertion weights 133 for storing the initial value of the ball input weight counter 134 is also given from the card 173. The card 173 may be a flexible disk such as a flexible recording medium. On the basis of these inputs, the ball-entry search processing unit 901
Is 135 in real time and 13 in batch
6. The number 139 of missed balls is output. Further, the set / updated values to the ball management table 150 and the tracking table 280 and the current value 137 of the incoming point portion raw data storage area are output. The real-time coin count 135 is data that is sent to the host computer at regular intervals of a short time (for example, 4 seconds), and the batch coin count 136 is data that is collectively sent to the host computer after the pachinko parlor is closed. It is used as (total number of balls entered on that day).

In the configuration of FIG. 1, the calculations of the above equations (1) and (2) are performed using the data conversion circuit section 200, but the data conversion circuit section 200 is omitted and this calculation is performed by the information processing device. You may go at 30. In that case, once RA
The raw data is taken into M76, the above-mentioned formula is calculated for the necessary points, and the data is written back to RAM76. Further, storage tables (137, 138, etc.) are separately provided for the processing that requires raw data.

FIG. 14, FIG. 15 and FIG. 16 show the table configurations used in the coin-in search process. FIG. 14A shows a coin search point table 130 that defines a coin search point.
Indicates. This table can define up to 10 points in this example. Vertical and horizontal coordinates Tx for each point
131 and Rx132 are set. The points are sequentially set from the point # 1 and the coordinates 0 are stored in the entry (area) that is not set. When searching for a coordinate 0,
Therefore, the search should be ended. FIG. 14 (b)
Shows the number-of-waits area 133 for entering a ball and the weight counter area 134. These functions will be described later. FIGS. 14C and 14D show the number-of-inserted-ball areas 135 and 136 in real time and in batch, respectively. FIG.
(A) shows the present value area 137 and the previous value area 138 of the incoming point portion raw data storage area. 10 points are prepared for each of the maximum 10 points in the pay-in point search table 130. Figure 15 (b)
Indicates a missed ball number area 139 for storing the number of missed balls, as will be described later.

FIG. 16A shows a ball management table 150 used consistently in this embodiment. This table includes a normal ball area 151 and a captured ball area 152. A normal ball means a ball that has been thinned by an incoming ball search, and a captured ball is an area that is caught after being missed by an incoming ball search (described later).
The ball captured in. The captured ball may return to a normal ball as described later. A ball registered in the ball management table 150 is referred to as a managed ball, including a normal ball and a captured ball. In the present embodiment, a maximum of 10 pieces (20 pieces in total) can be registered simultaneously for each of the normal balls and the captured balls. This is a numerical value that can be dealt with when a maximum of 10 normal balls are simultaneously present on the board. Normally, one pachinko ball is projected at about 600 ms, and one pachinko ball disappears within the winning hole or the out hole within a few seconds, so this level is considered to be sufficient. Areas 154 to 168 of 15 bytes (1 address and 1 byte) are prepared for one management ball. Reference numeral 154 shows an area of a used / unused flag indicating whether the management ball area is currently in an empty state or in use. Here, 0 indicates that it is empty and 1 indicates that it is in use. It should be noted that, in the present specification, a reference numeral indicating an area may be used as a content stored in the area for the sake of convenience. 155 is the current ball coordinates Tx156, Ty15
7 shows the type of fixed search frame (described later) in 7.
Here, 50 types of 0 to 49 can be designated. A value of 255 in this area 155 indicates that a modified frame to be described later is specified at that position. 158 and 159 are the strongest reaction coordinates Tx, which are candidates for the ball coordinates at the next time point of the current ball coordinates, respectively.
Rx is shown. The coordinates Tx and Rx correspond to the resolution of the matrix sensor and are values of 1 to 32, respectively. 160 shows the value of the strongest reaction. The value of the reaction value in this example is 0 to 255. Reference numeral 161 denotes a miss-waiting counter used in a prize winning ball search process described later, and the settable range of the value thereof is 0 to 99. Reference numeral 162 denotes an overlap waiting counter used in the overlap determination process described later, and the settable range thereof is 0 to 99. This area is used as a recovery waiting counter used for recovery processing of a captured ball, which will be described later, and the settable range is 0 to 99. Reference numeral 163 is a spare area. Reference numeral 164 is an overlap flag used in the overlap determination process, where 0 means that the management balls do not overlap, and 1 means that the management balls overlap. 165 to 168 are spare areas.

FIG. 16B shows a tracking table 280 for tracking the movement trajectory (movement point) of the control ball. The tracking table 280 sets the coordinates of each ball trace of a maximum of 10 managed balls to 1 for each of the normal balls and the captured balls.
Up to 28 can be stored. 128 in most cases
The number is enough, but if it exceeds this, the old coordinates are overwritten. The "pointer" indicates the position where the coordinates of the ball trail are set.

The various counters and flags in this embodiment are constructed by using one address of the memory.

Now, referring to FIG. 13, the procedure of the coin-in search process 901 will be described. This process is started every scan cycle (28 ms).

First, it is checked whether the pay-in weight counter 134 is 0 (921). This waiting time is longer than the time required for a pachinko ball to pass through the plurality of ball-striking points and shorter than the ball-striking cycle so that ball-hitting is surely detected and is not counted in duplicate. Set to the value. Here, since it is set by the number of scan cycles, it is set to about 17. Until the wait counter reaches 0, the counter value is decremented (-1) (9
29), the process ends. If the counter value becomes 0, it is determined that the waiting time has ended, and the process proceeds to step 922 and the subsequent steps. In step 922, the variable max that stores the maximum value of the detection data of the matrix sensor is cleared to 0. Therefore, in steps 923 to 928, the values of a plurality of coin-in search points are checked to find the maximum value of meaningful data. That is, the winning points # 1 to # 1
While it is not finished for 0 (923), and while the valid value is set in the table entry (924), the absolute value of the difference (change amount) between the current data and the previous value of the ball entry point is calculated. It is obtained as a variable dat (925), and it is checked whether the value is larger than a predetermined slice (threshold value or reference value) (926). In this slice, a different value can be set for each pay-in search point. Figure 11
As can be seen from the above, there is a difference in the degree of overlap between the detection unit area and the pachinko ball passage depending on each ball search point, and there is a difference in the distance from the surrounding metal rails. Can be reflected in the value. If it is smaller than the slice, it is determined that the value is not significant, and the process returns to step 23. If it is larger than the slice, if it is larger than the maximum value in the data examined up to now among the winning points # 1 to # 10 (927), that value is substituted for a new max (928). In this way, entry points # 1
The maximum value of the significant detected data change amount of # 10 is obtained. In step 928, the coordinates of the maximum winning point are stored as the vertex point.

When it is finished for the pay-in points # 1 to # 10 (923), or when it is determined that no valid value is set in the subsequent table entry (coordinate 0 is detected) (924), step 930. Go to. Here, it is checked whether or not the variable max is greater than 0, that is, whether or not a winning ball has been detected (930). If it is determined that there is no incoming ball, this process ends. When it is determined that there is a ball count of 135,1 for both real time and batch
36 is incremented (+1) (931). next,
The number of waits for entering a ball is 13 in preparation for the next incoming ball search process.
3 is set in the weight counter 134 (932).
Therefore, it is checked whether or not there is an empty entry in the ball management table 150 (FIG. 16A) (933). If there is no space,
The number of missed balls 139 is incremented as a missed ball (936), and this processing is ended. If there is a vacancy, it is registered as a new management ball in the ball management table 150 (934). That is, the used / unused flag 154 of the management ball is set to 1, and the stored coordinates of the vertices are stored in the current ball coordinates (current positions) 156 and 157. Also, type 1 of the fixed search frame at the current position
55 for fixed search frame type designation table 2 described later
Set by referring to 20. Further, the initial values of various counters and flags are set. Finally, the first coordinates are registered in the tracking table 280 for tracking the path of the pachinko ball on the board surface (935), and the process ends.

Next, a frame search process, that is, a search process of a ball reaction in a search frame will be described. Where the control ball moves from its current position to the next time
In a short time, it is estimated to be within a range around the current position. The search frame is for indicating such a range and regarding the point having the largest reaction value in the range as a new position of the management ball.

The structure of the search frame used in this processing and the method of designating it will be described with reference to FIGS.

FIG. 17 shows a fixed search frame (also simply called a fixed frame) used in this embodiment. This fixed frame is a frame based on a quadrangle, and its size and position are based on the current ball coordinates 182 (Tx = 8, Rx = 6 in the example in the figure), and are located in the upper left corner of the quadrilateral. Relative coordinates of the upper left corner 181 (Tx =
-2, Rx = -2) and the relative coordinates (Tx = 1, Rx = 2 in the example in the figure) of the lower right corner 183 of the lower right rectangle.

FIG. 18 shows a free search frame (also simply called a free frame) used in this embodiment. This flexible frame is a frame of unlimited shape, and all frame constituent points are specified by relative coordinates with reference to the current ball coordinates. In the figure, the circled number 1 is the current position, and the circled numbers 2 to 13 are the frame constituent points. The flexible frame is suitable when the direction in which the pachinko ball at the current position moves next is limited to a known narrow range of directions. The illustrated example can be applied to, for example, a point in the vicinity where a projected pachinko ball is released into the game area. Since it is necessary to check the search points in a short time, the number of points that can be checked at one time is limited. Therefore, it is useful to limit the check target in this way. Moreover, even if the same number of points are checked, the points can be set in one direction, which is advantageous in that high-speed ball movement can be dealt with.

What kind of search frame is set at which point may vary depending on the model of the pachinko game machine.

19 and 20 show the search order of such search frames. FIG. 19 shows a fixed search frame 18
A point search order of 0 is shown, and in this example, the process moves from the upper left corner downward, then shifts one point to the right and moves downward, and the same procedure is repeated until the lower right corner. FIG. 20 shows a point search order for the flexible search frame 184. In this example, searches are performed in ascending order of circled numbers. These are merely examples and the present invention is not limited to these.

FIG. 21 shows the software configuration of the frame search processing. This processing is performed by the frame search processing unit 190.
Is executed every scan cycle. The input is the parameter group uploaded from the card 173, the skip flag 230, and the read data 760 from the RAM 76. The parameter group includes a fixed search frame type designation table 220, a flexible search frame type designation table 222, a fixed search frame type information table 224, and a flexible search frame type information table 2.
26, and the overlap wait count 234. Details of these tables will be described below. The read data 760 used in this processing is calculation data in which the offset and slice are reflected in the raw data. The frame search processing section 190 updates the contents of the ball management table 150 based on these input data.

Before explaining the specific procedure of the frame search processing, the table configuration used in this processing will be described.

FIG. 23A shows an example of the structure of the fixed search frame type designation table 220. This table shows, for each 32 × 32 (or 1024) point, the type of fixed search frame assigned to that point. In this embodiment, 50 types can be used, and the value thereof is any one of 0 to 49. In addition,
When the flexible search frame is assigned to the point, the numerical value 255 is set. FIG. 23B shows a configuration example of the type specification table 222 of the universal search frame, and 49 types can be specified for each of 1024 points. The numerical value is any of 1 to 49. However, when the numerical value 0 is set, it indicates that a fixed search frame is assigned to the point.

FIG. 24A shows a structural example of the type information table 224 of the fixed search frame. In this example, 5
For each of the 0 types, the relative coordinates Tx and Rx of the diagonal points of the quadrangle based on the current position of the control ball as described above with reference to FIG. The range of Tx and Rx is -31

The range of x and Rx is −31 to 31.

FIG. 25A shows the skip flag 230. Since each process of this embodiment needs to be executed in each scan cycle, the skip flag 230 is set to ON at a specific point in the cycle to forcibly terminate the process in that cycle. belongs to. In such a case, in the present process, in order to prioritize the process of the normal ball having high importance, only the process of the captured ball is skipped. FIG. 25B shows areas 231 and 232 that store the number of overlaps indicating the number of overlaps and eliminations of the managed balls, and the number of eliminations of the overlaps. FIG. 25D shows an area 233 that stores the number of captured balls that have become normal balls. FIG. 25E shows the number of overlap wait times 234 indicating how many scan cycles the overlapping state is allowed when the overlapping of the management balls described later occurs. FIG. 25 (f) shows a miss waiting count table 505 in which it is possible to set, for each 1024 points, how many scan cycles to wait for a prize after missing a ball.
The settable range of the number of waiting times is 0 to 99 in the embodiment.

Referring to FIG. 22, the frame search processing section 190
The procedure of the in-frame reaction search process executed by will be described.
This process is executed for both the normal balls and the captured balls for each scan cycle.

Follow the steps below to manage balls in the ball management area #
The processes 1 to # 10 are sequentially executed (201), and when all are completed, this process is completed. Also, if the skip flag is ON, if it is a process for a captured ball (20
2), the process ends. If the used / unused flag 154 for the selected ball management area is 0 (unused), the process returns to step 201 (203). When the ball management area is in use, the frame type of the current position of the management ball is acquired from the fixed search frame type 155 or the fixed search frame type designation table 220 (FIG. 23) (2
04). If the value of that type is 255 (205),
Find the type of flexible search frame at the current position of the control ball from the flexible search frame type specification table 222,
Search within the free search frame of that type (20
7). That is, the reaction value (calculated data here) of each point designated in the frame is checked. If the type is not 255 in step 205, the search in the fixed search frame of the specified type is similarly performed (20
6). Next, the strongest reaction value in that frame and its coordinates are registered in areas 158 to 160 of the ball management table (208). Here, the case of a normal ball and the case of a captured ball are divided (209). In the case of a normal ball, whether there is a reaction in the frame (210) "There is a normal ball reaction" 21
The process is divided into 1 and “No normal ball reaction” 214. In the case of a captured ball, whether there was a reaction within the frame (213)
“There is a captured ball reaction” 216 and “No captured ball reaction” 21
Processing is divided into 9.

26 and 27, the detailed flow of step 211 of "with normal ball reaction" will be described.

First, the coordinates 158 and 159 of the strongest ball reaction in the search frame are acquired from the ball management table 150 (2111). A wait-for-miss mode, which will be described later, is reset (2112), and overlap determination is performed (2113). The overlap determination is a process when balls in a plurality of search frames overlap, and details thereof will be described later. If no overlap occurs (2114), the process proceeds to the process of FIG. If there is an overlap,
The overlapping flag 164 of the management balls is checked (21
15). If the overlap flag is OFF, the overlap flag is turned ON (2116), the "overlap number" is incremented (2117), and the process proceeds to step 2119. If the overlap flag is already ON, the overlap wait counter 162 is incremented (2117) and the process proceeds to step 2119. In step 2119, the overlap waiting counter 16
2 is compared with the overlap wait count 234 to check whether the overlap wait has been completed. If it has not been completed, this processing ends (2119). If it is completed, the normal ball is deleted from the ball management table 150 (2120) and the tracking table 280 is cleared (2121). As described above, the normal balls are not deleted immediately when the overlap occurs, but are deleted if the overlap still occurs after a certain grace period.

In step 2114, when there is no overlap, the process moves to FIG. 27 and the out-ball search is performed (212).
2). The details of this will be described later. When it is determined that this ball is an out ball, the overlap flag 164 is checked (212
4). If the overlap flag is OFF, the process proceeds to step 2126. If it is ON, the overlap elimination number 232 is incremented and the process proceeds to step 2126. In step 2126, the number of out balls 381 is incremented. Then, the normal ball is deleted from the ball management table 150 (2
128), clear the tracking table 280 (212)
9).

If it is determined in step 2123 that the normal ball is not an out ball, first, the overlap flag 1
Check 64 (2130). If this flag is OFF, the process jumps to step 2134. If it is ON, the overlap elimination number 232 is incremented (213
1), the overlap flag 164 is turned off (2132), and the overlap waiting counter 162 is reset (2133).

In the following step 2134, the ball management table 150 is updated with the strongest ball reaction coordinates 158, 159 as the current ball coordinates 156, 157 (2134). Also, the fixed search frame type 155 at that position is updated. Further, the tracking table 280 is updated (coordinates are added) (2135), and the process is terminated.

According to FIG. 28, the processing 21 without the normal ball reaction
The detailed procedure of No. 4 will be described.

First, the overlap flag 164 is checked (214
1) When this flag is OFF, whether or not the miss waiting has been completed is checked by the count value of the miss waiting counter 161 (2142). If it is not completed, the missed waiting counter 161 is incremented (2153), and this processing is ended. If the waiting for missing is completed, a prize search is performed (2143). The details will be described later. If it is not determined that the prize is won (2144), it means that the normal ball is lost, so the number 139 of missed balls is incremented (2148), and this processing is ended. When it is determined that the prize is won, the winning locus creating process described later is performed (2145). Then, the normal ball is deleted from the ball management table 150 (2146) and the tracking table 280 is cleared (2147).

If the overlap flag is ON in step 2141, it is checked whether or not the overlap waiting is completed (214
9) If it is not completed, the overlap waiting counter is incremented (2152) and this processing is ended. When the overlap waiting is completed, it means that the overlap has not been resolved even during a certain grace period, so it is determined that the normal ball is due to an erroneous detection or the like, and it is deleted from the ball management table 150 (21
50), clear the tracking table 280 (215
1).

According to FIG. 29, the processing 21 with the captured ball reaction
The processing procedure of No. 6 will be described.

First, the coordinates 158 and 159 of the strongest ball reaction in the search frame are acquired from the ball management table 150 (2161). Next, the waiting-for-miss counter 161
Is reset (2162), and overlap determination is performed (216
3). The detailed flow of overlap determination will be described later.
When the overlap occurs (2164), the revival waiting counter 162 is reset (2165), and the ball management table 15
This is deleted from 0 (2166), and this processing is ended. As described above, in the present embodiment, when an overlap occurs in the captured balls, it is determined that the detection is erroneous and the captured balls are immediately deleted.

If it is determined in step 2164 that there is no overlap, the recovery waiting counter 161 is decremented (2167), and it is determined whether the recovery waiting is completed based on the count value (2168). When it is completed, the captured ball restoration process described later is performed (2169). continue,
The captured ball is deleted from the captured ball area (2171), the number of revived balls 233 is incremented, and this processing ends.

If it is determined in step 2168 that the waiting for restoration is completed, an out-ball search process (detailed later) is performed (2173). If it is determined that the resurrection ball has become an out ball (2174), the resurrection ball number 233 is incremented (2175), and the out ball number 381 is incremented (2176). Then, the captured ball is deleted from the ball management table 150 (2178), and this processing ends. When it is not determined as an out ball in step 2174, the strongest ball reaction coordinates 158, 159 are set to the current ball coordinates 156.
157 (2179). Also, the fixed search frame type 155 at that position is updated. Further, the tracking table 280 is updated (2180), and this processing ends.

Next, the processing procedure of the processing 219 without a captured ball reaction will be described with reference to FIG.

First, it is checked whether the waiting for overlooking has been completed (2
191), if not completed, the missed waiting counter is incremented (2198), and this processing ends. If it is completed, a prize search described later is performed (2192),
It is checked whether or not a prize has been won (2193). If no prize is won, the process jumps to step 2196. If you win
The winning locus creating process described later is performed (2194), and the number of revival balls 233 is incremented (2195). In step 2196, the ball management table 1 for the captured ball.
It deletes from 50 (2196), clears the tracking table 280 (2197), and ends this processing.

Next, the ball reaction search in the capture block will be described. The catching block was missed in the incoming ball search,
Alternatively, it is a predetermined on-board area for catching a ball missed by tracking with the search frame. Balls captured by such capture blocks are called capture balls. In this embodiment, up to 30 acquisition blocks can be set. Also, each capture block 241 can specify up to 20 points as its block constituent points.

FIG. 31 shows an example of setting a capture block. As shown in this example, the points that make up each block are
It is specified by Tx and Rx coordinates.

Although the detailed flow will be described later, the operation of the capture block will be outlined with reference to FIG. FIG.
As shown in (a), the point of the strongest reaction (reaction value “50” in the figure) when the reaction value (calculation data) of the point in the capture block 241 is the reference value or more is used as a capture ball.
It is registered in the captured ball area 152 of the ball management table 150 described above. When this captured ball is confirmed by the method described below with certainty that it may not be an erroneous detection, this pachinko ball is managed as a normal ball thereafter. However, as shown in FIG. 32 (b), when the search frame of any of the managed balls at that time and the capture block overlap, the ball reaction search in the capture block is not performed for the overlapping points. This is because in the search frame, the influence of the currently registered management balls is great and it is difficult to accurately determine the captured balls. The same applies when it overlaps with the pay-in point search point.

FIG. 33 shows the software configuration of the search process in the capture block. This processing is executed by the captured block search processing unit 250 every scan cycle. The capture block search processor 250 uses the card 173 to capture point designation table 270 and capture slice level 2
73 and the lead-in search point table 130, and read data (calculated data) from the RAM 76.
Receive 760. Further, the settings of the skip flag 230 and the capture prohibition flag table 272 are also received. The ball management table 150 and the tracking table 280 are updated based on these.

FIG. 35 shows the table structure used in the captured block search processing. FIG. 35 (a) shows a capture point designation table 270 that defines the coordinates of up to 20 points that make up each of up to 30 blocks.
When searching, block # 1 is searched in sequence. When the coordinate 0 is detected on the way, the search ends. FIG.
(B) shows a capture prohibition flag 272 for setting capture permission (0) or capture prohibition (1) for each of 1024 points. This flag 272 is for prohibiting the capture within the range of the search frame of the tracked control balls, and is set in the processing of FIG. FIG.
(C) shows a slice level for capturing that functions as a reference value when determining whether or not a captured ball.

As shown in FIG. 34, the captured block search processor 2
A detailed flow of the ball reaction search process in the capture block 50 will be described.

The following steps 252 to 264 are successively repeated for 30 captured blocks (251), and this processing is ended. First, the following steps 253 to 259 are performed until the processing is completed for all the capture points # 1 to # 20 of the capture block (252). If the skip flag is ON, this process ends on the spot (253). If the capture point is overlapped with the coin-in search point, the process moves to search for the next capture point (254). Also, when the capture prohibition flag of the capture point is ON, the process moves to search for the next capture point (25
5). For the capture points that have passed these condition determinations, the result of subtracting the capture slice level from the response data (calculation data) is set as new response data (256). If this reaction data is not positive, it is regarded as not significant data, and the process moves to the next capture point. If it is positive, it is compared with the variable max (258), and if it is larger than max, this reaction value is set as a new max (25).
9). In this way, for the capture block, the maximum data of the significant reaction data is obtained as the variable max. If this variable max is not positive (260),
Assuming that there is no captured ball, the process returns to step 251 to search for the next captured block. If the variable max is positive, it is determined that there is a captured ball, and a free space is acquired in the captured ball area 152 (FIG. 16) of the ball management table 150 for this captured ball registration (261). If there is no vacancy, the current registration is not performed and the process returns to step 251. If there is a free space, a new captured ball is registered in the free area of the ball management table 150 (262). It is also registered in the corresponding capture area of the tracking table 280 (263). Finally, the number of times of waiting for the recovery of the captured block (described later in FIG. 38) is set in the recovery waiting counter 163 (FIG. 16) of the captured ball (2).
64).

Next, the recovery processing of the captured ball thus captured will be described. Since the captured ball registered in the ball management table 150 may have been detected due to the influence of noise or the like, it is determined that the captured ball will not be treated as a normal ball immediately after being captured. Therefore, when it is possible to continuously track the image for the preset number of times of revival in the scan cycle, it is revived as a normal ball. At the time of revival, the information of the ball is moved from the revival ball area to the normal ball area. However, if there is no space in the normal ball area, the resurrected ball will be discarded. This is because the current normal balls are preferentially tracked. When the captured ball overlaps with another ball while waiting for recovery, the captured ball is deleted from the ball management table 150 by the overlap determination processing described later.

FIG. 36 shows the software configuration of the captured ball restoration process. This processing is executed by the captured ball rejuvenation processing unit 331 in the processing shown in FIG. 29, receives information of the reversion waiting count table 330 from the card 173, and refers to, updates, and tracks the ball management table 150. 28
0 is updated.

FIG. 38 shows a table used for the recovery process of the captured balls. This table is a revival waiting count table 330 in which the revival waiting count can be set for each capture block.

With reference to FIG. 37, the flow of the recovery process of the captured ball will be described. This process is executed for each captured ball in each scan cycle.

First, the revival waiting counter 16 for the captured ball
It is checked whether 3 has become 0, that is, whether the number of times of waiting for the number of revival has been waited (321). If not, this process ends. If the counter value is 0, it is checked whether there is a vacancy in the normal area of the ball management table 150 (322). If there is no space, the process ends. If there is a vacancy, the information of the captured ball registered in the captured area is moved to the normal area (323). Similarly, the information of the captured ball registered in the captured ball area of the tracking table 280 is moved to the normal area (324), and the process is ended. In this way, if a predetermined condition is satisfied within a certain grace period, the captured ball is upgraded to a normal ball as a missed regular ball.

Next, an out ball search for detecting a ball that has entered the out hole will be described. This process is executed every scan cycle. As shown in FIG. 39, an out-ball search point portion (also referred to as an outline) 361 is provided above the out hole 15 in the game area so that the pachinko ball cannot reach the out hole 15 unless it passes through the out hole 15. There is no winning hole below the outline 361. When the ball tracked by the search frame is detected on this outline or when it is detected that it exceeds the outline, it is determined that the pachinko ball has entered the out hole 15. This outline 361
Up to 32 search points can be set in this embodiment.

FIG. 40 shows the software structure of the out-ball search process. This process is performed by the out-ball search processing unit 360.
Is executed every scan cycle. The out-ball search processing unit 360 outputs the out-ball number 381 and the overlap elimination number 232 based on the information of the out-ball search point table 380 given from the card 173 and the read data (calculation data) 760 from the RAM 76.
The ball management table 150 and the tracking table 280 are updated.

FIG. 42 shows a table structure used in the out-ball search process. FIG. 42A shows an out-ball search point table 380 in which up to 32 out-ball search points can be designated by the coordinates. The coordinates are sequentially set from the point # 1, and when the coordinate 0 is detected, the search is ended even in the middle. FIG. 42B shows an out-ball number 381 that stores the number of out-balls. Since it has an area of 2 bytes, up to 65535 numerical values can be stored.

According to FIG. 41, the out-ball search processing section 360.
The processing flow of is described. This process is shown in FIGS.
It is called in the process shown in (1) and is executed for each management ball (normal ball and captured ball).

In this process, the following steps are repeated for each out-ball search point (361), and the process ends. First, with respect to the search point Rx, the coordinate Rx of the maximum ball reaction in the search frame of each management ball (normal ball)
Is checked (362). If there is no match in any search frame, the process returns to step 361 to process the next search point. For the matching search frame, the coordinate Tx of the maximum ball reaction is the search point T
It is checked whether it is equal to or larger than x (it is on the lower side) (363). If not, the process returns to step 361. If not, it is determined to be an out ball (364). If a ball enters the out hole, the managed ball is moved to the ball management table 15
It is necessary to delete from 0 and clear the corresponding part of the tracking table 280, but in that case, the ball will be lost by the tracking of the ball by the search frame. It is performed collectively in the detection process.

Next, the winning ball search processing will be described.
The fact that the pachinko ball has entered the winning hole means that there is no subsequent ball reaction when the current position of the managed ball enters the area near the winning hole, that is, if it is missed, there is a high possibility that it has entered the winning hole. Use that fact to make a determination. However, instead of overlooking and immediately determining the winning, the winning is determined after waiting for a certain grace period, that is, the scan cycle of the number of waiting times for missing. This reduces the possibility of misjudgment. As shown in FIG. 43, in this embodiment, for each of the number of winning holes (15), nine points in the vicinity thereof are designated as the winning search point portion 460.

FIG. 44 shows the software configuration of the winning ball search processing. This processing is executed by the winning ball search processing unit 470 at each scan cycle. Prize winning ball search processing unit 47
0 is a parameter group from the card 173 (a prize ball search point table 500, which will be described later, and a missed waiting count 505)
And payout number table 507) and winning flag 5
10 and read data from RAM 76 (calculation data)
And 760 as input data. Further, the tracking table 280 and the ball management table 150 are referred to / updated. Furthermore, the number of winning balls (batch) 520 and the number of winning balls (real time) 522 are updated. The batch and real-time meaning of the number of winning balls is the same as the number of winning balls described above.

Before explaining the processing procedure of winning a prize search, the table configuration to be used will be explained.

FIG. 46A shows a prize ball search point table 500 in which the coordinates of nine prize ball search points in the vicinity of each prize hole are set. The setting of coordinate 0 is used for ending the search. FIG. 46B shows a payout ball number table 507 in which the number of payout balls is set for each winning hole. This is data for calculating the number of payouts for each winning hole, and the number of payouts for the winning hole is calculated by (the number of payout balls) × (the number of payout balls). The number of coins to be released is transmitted to the host computer periodically (for example, every 4 seconds) together with the number of balls to be inserted and the number of balls to be out. If the capacity of the storage area is exceeded within the time interval, it will be an overflow.

FIG. 48 shows a winning flag 510 provided for each winning hole. The content of this flag indicates that when 0, no ball is won in the winning hole in the same record (same scan cycle), and when 1, it is winning in the winning hole in the same record. . The role of the winning flag 510 is as follows. Since the winning prize search process is performed in the winning ball search process 470, it is also sequentially executed for each management ball. For a winning hole in which it has already been confirmed that a certain managed ball has won, it is considered that no other managed ball will enter at the same time, and the winning flag 510 is turned on. Thereafter, within the same record, a winning search for that winning hole is made. Is omitted. This can reduce the processing time. The winning flag 510 is reset every scanning cycle (at the latest when the winning ball search process is started). FIG. 48 shows 1024
A locus table 512 for accumulating the number of times the ball has passed for each of the points is shown.

FIGS. 49 (a) and 49 (b) show prize ball number tables 520, 522 storing the number of prize balls in batch and in real time for each prize hole.

FIG. 45 shows a flow of the prize retrieval processing 470. This processing is called in the processing shown in FIGS. 28 and 30.

The following steps are repeated for each of the winning holes # 1 to # 15 (481) and this process is completed. At step 482, whether the winning flag 510 is ON,
That is, it is checked whether or not the prize is won in the same record. If the winning flag 510 is ON, the process returns to step 481 to determine the next winning hole. The winning flag is O
If not N, the following steps are sequentially repeated for each of the winning search points # 1 to # 9. If the point is not designated (484), the process returns to step 481. If so, it is checked whether the current position of the management ball matches the search point (485). If they do not match, the process returns to step 487 to check the next search point. If they match, it is determined that the player has lost sight of the prize, and the prize is awarded. Therefore, the winning flag 510 is set to O.
N (486). Next, the real-time and batch prize numbers 522 and 520 are respectively incremented (488 and 489). The above-mentioned payouts are also calculated. This completes the winning search process.

With regard to the winning balls thus determined,
As shown in FIG. 50, the loci (movement points) for each scanning cycle from winning to winning are accumulated in the tracking table 280 (FIG. 16 (b)) as shown in FIG. Such a moving point sequence is set to 1024 as shown in FIG.
Trajectory table 5 having a storage area for each point
By accumulating in 12, the trajectory of the ball appears. This is because if the host computer or the like reads out the contents of the trajectory table 512 and displays it on the display, the trajectory of the ball can be visually recognized.

FIG. 52 shows the software configuration of the winning ball locus creating process. This processing is executed by the winning ball locus creation processing unit 550 every time a winning is detected in the processing shown in FIGS. 28 and 30. Prize ball locus creation processing unit 5
50 writes to the trajectory table 512 based on the contents of the tracking table 280.

As shown in FIG. 54, the table used for this processing is an integrated flag table 570 that stores a flag indicating the presence or absence of integration for every 1024 points. In this example, when this flag is 0, it indicates that integration has not been completed and when this flag is 1, integration has been completed. The initial value of the flag is 0.

The procedure of the winning ball locus creating process will be described with reference to FIG.

First, from the tracking table 280, the number of registrations (the number of registered point coordinates) of the winning ball is acquired (551). Therefore, the following processing is repeated for the number of registrations (552). In step 553, one moving point is extracted from the tracking table 280 (553),
The accumulated flag table 570 is referred to check whether the point has been accumulated (554). If the integration has been completed, the process returns to step 552 to move to the next movement point. If the integration has not been completed, the integration completed flag is turned on (555). As a result, even if the same points appear thereafter, the trajectory table 512 will not be integrated. Next step 55
At 6, the locus table 512 is integrated for the movement point. If this is executed for all movement points, the locus table 51 as shown in FIG.
A cumulative result of 2 is obtained.

Next, the overlap judgment will be described. In this case, when the search frames of a plurality of management balls registered in the ball management table 150 completely match each other, the registration of one ball is deleted as a ball due to an erroneous detection under a predetermined condition. Is. Specifically, it is detected whether or not the maximum reaction point in the search frame of a certain management ball matches the new position of another management ball that has already been updated. As described above, in the case of normal balls, the registration is deleted when the predetermined grace period (scan cycle corresponding to the number of overlap waiting times) continues to overlap. When the captured ball overlaps with another managed ball, the registered ball is immediately deregistered. This is because the captured balls are less reliable than the normal balls.

FIG. 55 shows the software configuration of the overlap determination processing. This processing is performed by the overlap determination processing unit 630.
This is a process executed in the process shown in FIGS. 26 and 29, and includes a ball management table 150 and a tracking table 2.
Update 80.

The processing procedure of the overlap determination processing unit 630 will be described with reference to FIG.

First, it is checked whether the management ball is a normal ball or a captured ball (631). If it is a normal ball, the process proceeds to step 632,
If it is a captured ball, the process proceeds to step 640. Step 632
Then, normal balls # 1 to # 10 to be compared with the normal balls
The processes of the following steps are sequentially repeated for (excluding oneself), and the present process ends. The reason why the captured ball is not included in the comparison target is that the management ball is a normal ball and the normal ball is not deleted even if the normal ball overlaps with the captured ball. The overlap between the captured ball and the normal ball is determined in step 641 described later. In step 633, it is checked whether or not the new ball position of the player is the same as the already moved position of the other managed balls to be compared. If they are not the same, the process returns to step 632 and moves to the next comparison target ball. If they are the same, it is determined that the normal balls have overlapped (634).

When the management ball is a captured ball (63
1), normal balls # 1 to # 10 and captured ball # 1 as comparison targets
For each of # 10 to # 10 (excluding itself), the following steps are sequentially performed (640). Step 641
In, it is checked whether or not the new ball position of the player is the same as the already moved position of the other managed balls to be compared. If they are not the same, the process returns to step 640 to move to the next comparison target ball. If they are the same, it is determined that an overlap has occurred for the normal ball (642).

The pachinko ball detecting device according to the present invention may be installed in all the pachinko game machines of the pachinko parlor, or may be installed one by one for different models. Alternatively, it can also be used for applications such as inspecting the characteristics of a specific pachinko game machine.
