Description

  The present invention relates to a ball game machine that launches a game ball in a game area provided on a game board surface and plays a game.

In a ball game machine that plays a game based on a game ball that fires a game ball, such as a pachinko game machine, into the game area and flows down in the game area, the above-mentioned game area is partitioned on the game board surface, A guide rail is installed to guide the launched game ball into the game area.
The guide rail is provided along a substantially circle, but there is a portion where the guide rail overlaps inside and outside, and a game ball that has been fired through the double portion passes through and is introduced into the game area.

In the game area, there are electric winning tulips such as electric tulips, attackers, etc. that can be opened and closed, and fixed winning openings such as general winning openings (including start winning openings that do not have an electric chew). Is provided. The fixed winning opening is formed, for example, in a box shape opened upward, and protrudes from the game board surface. A game ball can flow into the inside through an opening opened above the box-shaped winning opening.
In addition, on the upper side of the winning opening, gaming nails having a function such as distributing the game balls to the side approaching the opening of the winning opening and the side moving away from the opening are in a state where a plurality of game nails are implanted on the board surface. ing.

  In the arrangement of these game nails and winning holes, it is considered to prevent the game balls from staying in the game nails and the like while being prevented from flowing down. In addition, when a plurality of game balls are clogged between game nails or the like in the vicinity of the winning opening to form a ball pool (a plurality of game balls accumulated based on the ball clogging), the accumulated game balls are There is a case where another game ball is guided to the winning opening, and in this case, the winning rate of the gaming ball at the winning opening becomes extremely high.

So, using a magnet to guide the game ball, intentionally generate a ball clog, accumulate the ball, form a ball pool, illegally increase the winning rate of the winning mouth, steal many prize balls There may be cases where cheating is attempted.
In this case, if the ball pool is completed, no magnet is required, and many prize balls can be obtained by continuing the game as it is.

  Injustice using a magnet is not limited to the above-mentioned ones, but as described above, a game ball is directly guided to a winning opening by a magnet, or a non-contact type sensor for detecting a game ball (for example, passing inside a coil). A sensor that detects a change in impedance of a coil by a game ball) is known to malfunction due to magnetic force.

  For such fraudulent acts using electromagnets, devices that can detect magnetic force, such as magnetic sensors, are used in gaming machines, and there is a possibility that fraudulent acts are being conducted based on the detection of magnetic force. Is known (for example, see Patent Document 1 to Patent Document 4).

Japanese Utility Model Publication No. 06-3386 JP 2007-185285 A JP 2004-147687 A JP 2004-81232 A

  By the way, in the method of forming a ball pool by generating a ball clogging by a magnetic force in the vicinity of the winning opening as described above, if a ball clogging is generated by a magnet and the ball pool is formed as it is, the magnet is further increased. Therefore, it is possible to obtain a lot of prize balls by an operation using a magnet for a short time, and the prize balls can be obtained relatively inconspicuously.

  Here, ball clogging is likely to occur where there are many game nails and various winning holes that protrude from the game board surface. For example, a plurality of (for example, two or three) general winning holes are arranged so as to be substantially along the guide rail, and a number of game nails for changing the flow direction of the game ball are planted correspondingly. If it is, it is easy to generate ball pool.

  In other words, where there are multiple winning holes and guide rails close to each other and there are guide rails below the winning holes, not only game nails and winning holes but also guide rails are involved in the formation of the ball pool. It is in a situation where a pool is easily formed.

Further, it is known that, depending on the type of pachinko gaming machine, the guide rail and the winning opening are arranged very close to each other so that a ball pool can be formed relatively easily.
Therefore, by providing a magnetic sensor that intensively detects magnetism in the vicinity of the winning opening inside the guide rail, it is possible to accurately detect and deal with fraudulent acts.

  However, the detection range of the magnetic sensor is generally narrow, and many magnetic sensors are required to cover a relatively wide range of the game area from the back (back) side of the game board surface. There are also a certain number of cases where detection sensors are concentrated in places where there is a high possibility of fraud due to magnets, for example, in the vicinity of the above-described general winning opening in the vicinity of the guide rail or in the vicinity of the starting winning opening. Magnetic sensor is required.

  On the back side of the game board surface, there are a flow path for guiding the game balls discharged from the prize opening to the back of the game board to the outside of the game machine, various devices that penetrate the game board and protrude to the back side, a display, A light emitting device using various LEDs, a driving device for various movable members, and the like are arranged, and various circuit boards (including a control circuit main board and sub board and a wiring connection board) are arranged. Has been.

Therefore, in order to be able to detect magnetism in many parts of the game area, it is difficult to dispose many magnetic sensors on the back of the game board, and the magnetic sensors are concentrated in some areas. It is also difficult to place. On the other hand, if the installation location of the magnetic sensor is secured, the arrangement of the display and various members arranged so as to protrude to the back side of the game board is limited.
In Patent Document 1 to Patent Document 4, attempts have been made to detect fraud more reliably by performing various devices on a device capable of detecting magnetism, but this is not always sufficient.

  The present invention has been made in view of the above circumstances, and does not detect a magnet, but detects a fraud by detecting a ball pool in the vicinity of a guide rail formed using a magnet. It is an object of the present invention to provide a ball game machine that can be easily placed in a non-game area on the front side (board side) of a game board and can easily detect an illegal act that causes a ball pool.

In order to solve the above-mentioned problem, the ball game machine according to claim 1, a game board provided with a plurality of winning holes and a plurality of game nails for winning a game ball,
A bullet ball having a guide rail provided on the surface of the game board and defining a game area so as to regulate a flow range of the game ball and standing up so as to guide the shot game ball into the game area. In gaming machines,
At least one predetermined winning port of the winning ports is provided closer to the guide rail than the center of the game area,
On the side facing the non-game area opposite to the side facing the gaming area of the guide rail in the vicinity of the predetermined winning opening, the predetermined winning opening and the guide rail on the gaming area side through the guide rail. A game ball detecting means capable of detecting a game ball passing between the surfaces is provided;
When the game ball detecting means detects a stay of the game ball for a predetermined time or more, a signal output means for outputting a signal indicating that the stay of the game ball is detected is provided.

  In the first aspect of the present invention, the side facing the opposite side (outside) of the gaming area of the guide rail having a predetermined winning opening such as a general winning opening in the vicinity thereof, that is, a non-game area that is not a gaming area is faced. A game ball detecting means capable of detecting a game ball passing between the predetermined prize opening and the guide rail via a guide rail is provided.

  In this game ball detecting means, since the ball normally passes between the guide rail and the predetermined winning opening without stopping, even if the ball is detected, the detected ball moves immediately and cannot be detected. . That is, the game ball passing between the guide rail and the predetermined winning opening is detected by the game ball detection means for a short period of time.

  On the other hand, if a ball pool is generated between the guide rail and the predetermined winning opening, the game ball does not move, and the detected game ball does not move and disappears and continues to be detected. Therefore, if the game ball detection means continues to detect the game ball without interruption after the game ball is detected, a ball pool has occurred.

For example, if a game ball is detected for a predetermined time long enough to prevent erroneous determination by the game ball detection means, it is determined that a ball pool has been generated and a signal indicating the occurrence of the ball pool is output. Thus, the occurrence of the ball pool can be notified.
At this time, the game ball detection sensor is provided on the game board surface (the front side of the game board) which is the side of the game board where the game area is located, and in the non-game area outside the game area. The game ball detecting means can be arranged without being affected by the arrangement of various devices and members on the back side. For this reason, it is possible to reduce the number of magnetic sensors in the vicinity of the predetermined winning opening of the guide rail, and to arrange game ball detecting means instead, and to reduce the number of magnetic sensors to be arranged on the back of the game board. Can be reduced.

Moreover, it is possible to improve the fraud discovery rate by using the magnetic sensor and the game ball detecting means together.
In addition, as the game ball detecting means, a reflective optical sensor or a proximity sensor can be used effectively, and can be introduced at a relatively low cost. In addition, as the game ball detection means, a configuration that detects a game ball passing through a chucker or a winning opening, a count when paying out a game ball (prize ball), and other game balls is basically used. A similar configuration can be used. In addition, the control device side can use a conventional configuration for connection with a sensor for detecting a game ball as it is. Therefore, the present invention can be easily introduced into a ball game machine.

When a reflective optical sensor is used, for example, a small slit is formed in the guide rail, or a part of the guide rail is made of a transparent synthetic resin, so that a game in the game area can be viewed from outside the game area. It is necessary to apply light to the sphere and to receive reflected light from the game sphere.
In addition, the probability that a ball pool naturally occurs is not zero, and a ball pool may occur regardless of fraud with a magnet, but in this case as well, the winning rate of game balls at the winning opening may increase. Therefore, it is necessary to eliminate the ball pool, and when a signal indicating the occurrence of the ball pool is output, it is preferable to cause the game store staff to eliminate the ball pool as an error.
Therefore, the game ball detecting means can be used effectively even when the ball pool naturally occurs rather than the fraud of the magnet.

The bullet ball game machine according to claim 2 is the invention according to claim 1, wherein the guide rail is bent so as to divide the game area into a substantially circular shape and is erected on the game board.
The predetermined prize opening is provided in the game board in a box shape opened upward,
It flows down from above while being connected to the top and bottom at a distance lower than the highest position game nail planted in the game area and along the curved surface shape of the guide rail. Multiple left and right positions are arranged to accept incoming game balls,
The game ball detecting means includes
Downward from the portion of the guide rail that intersects the horizontal line passing through the upper end of the upper predetermined winning port located above the predetermined winning port at least one of the predetermined winning ports that are vertically connected, On the gaming area side of the guide rail up to the portion of the guide rail that intersects a vertical line passing through the side of the gaming area center side of the lower predetermined winning opening arranged below the upper predetermined winning opening It is characterized by being provided at a position where at least one of the game balls staying in contact with or close to the surface area can be detected.

In the invention according to claim 2, the game ball detecting means is arranged on the non-game area side of the guide rail corresponding to the position where the ball pool on the guide rail corresponding to the predetermined winning opening is highly likely to occur. Will be.
Therefore, it is possible to detect the ball pool with a single game ball detecting means for a plurality of predetermined winning holes arranged in the vicinity of the guide rail, and the cost can be reduced.

According to the present invention, by using a magnet to generate a ball pool without using a magnetic sensor, a fraudulent act for obtaining a winning ball by increasing the winning rate of a winning opening near the ball pool is detected without using a magnetic sensor. Therefore, the number of magnetic sensors can be reduced. Further, the game ball detecting means for detecting fraud may be a reflection type optical sensor or a proximity sensor, and these sensors may be arranged on the outer non-game area side, not on the inner side corresponding to the game area of the guide rail. it can.
Therefore, the game ball detecting means can be easily arranged as compared with the case where the magnetic sensor is arranged on the back side of the game board surface.

Embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, a pachinko gaming machine 1 according to an embodiment is a gaming machine that allows a player to play a game based on supply of game media (for example, a game ball, a medal, etc.). It is a ball game machine that plays a game by firing inside.

  The pachinko gaming machine 1 includes a machine frame 2 that is attached to an island facility in a rectangular frame shape, and a storage unit that is attached to the machine frame 2 so as to be openable and closable, and that accommodates a game board 3 (shown in FIG. 2). The front frame 5 and a glass frame 6 attached to the front side of the front frame 5 in a door shape so as to be opened and closed are provided.

  A transparent plate 8 (double glass plate or double transparent resin plate) is fitted into the glass frame 6 so that a game area 7 described later of the game board 3 can be visually recognized. In addition, a front board 9 is provided below the glass frame 6 of the front frame 5, and the front board 9 is provided with a tray 10 that stores game balls and supplies them to the launching device, and a rotary operation handle 11. ing.

As shown in FIG. 2, a game area 7 is formed in a portion surrounded by the guide rails 12 and the like on the front (front) F of the game board 3 and covered with the glass frame 6.
The guide rail 12 is formed in a substantially circular shape, but the left portion thereof is partially doubled in a spiral shape, and is divided into an outer guide rail 13 and an inner guide rail 14. In the portion where the guide rails 12 are doubled, the inner guide rails 14 define the game area 7.

A space 15 between the inner guide rail 14 and the outer guide rail 13 guides the game ball 9 launched by the game ball launcher H into the game area 7. The guide path 15 communicates with the game area 7 at the end portion M of the guide rail 14 on the inner side of the upper left portion toward the game board 3 (the portion where the guide rail 13 is doubled to one).
Moreover, the guide rail 12 is comprised from the part which consists of a metal plate part, and a synthetic resin, for example.

  In the game area 7 surrounded by the guide rails 12 on the surface of the game board 3, various fluctuation (movable) prizes such as electric chews, attackers, blades, etc., not shown, are selected according to the type of each ball game machine. A device is provided, and a fixed winning opening such as a start winning opening and a general winning opening without electric chews are provided.

  2 and 3, two winning ports (general winning ports) 16 are illustrated as predetermined winning ports provided closer to the guide rail 12 than the central portion of the game area 7 in the fixed winning ports. . In addition, on the upper side of an opening (not shown) opened above the winning opening 16, the game ball 9 is guided to the winning opening 16 (opening), the side approaching the winning opening 16 and the side away from the winning opening 16. A large number of game nails (failure nails) 17 that change the flow direction of the game balls that come into contact therewith are planted.

2 and 3, only the game nail 17 that becomes the game nail 17 and the top nail 25 in the vicinity of the above two winning holes 16 are illustrated as the game nail 17. The ceiling nail 25 is the gaming nail 17 arranged at the top in the game area 7, and the other gaming nails 17 other than the winning hole 16 and the ceiling nail 25 illustrated are arranged below the ceiling nail 25. ing.
The winning opening 16 is provided so as to protrude forward from the board surface in the gaming area 7 of the gaming board 3, and the distance between the front of the winning opening 16 and the back of the glass frame 6 is considerably narrower than the diameter of the gaming ball 9. 9 can not enter. In FIG. 4, reference numeral 24 denotes an out port for discharging game balls that have not won any winning port from the game area 7.

  The winning opening 16 is provided in a box shape so as to cover an opening through which the game ball of the game board 3 flows out from the front F side to the back B side, and the back and top surfaces of the box are open. It has become. Accordingly, an opening O (shown in FIG. 3) for winning a game ball is formed on the upper surface side of the winning opening 16. Further, the two winning openings 16 are located at the lower left portion of the game area 7 and close to the curved portion so as to incline downward from the top toward the right of the guide rail 12 (inner guide rail 14). Is provided.

  In addition, the two winning openings 16 arranged on the left and right are spaced apart by a distance D wider than the diameter of the game ball through which the game ball can pass. Further, the two winning openings 16 arranged on the left and right are arranged along the guide rail 12 that is inclined downward toward the right as described above, and the right winning opening 16 is lower than the left winning opening 16. It has become. Further, the upper end of the right winning opening 16 is lower than the lower end of the left winning opening 16. Further, the left winning port 16 above the right winning port 16 is arranged so as not to interfere with the winning of the game ball flowing down at least substantially from the top to the right winning port 16.

Further, the two winning holes 16 and the guide rail 12 are in close proximity to each other, but the gap C (see FIG. 5) is wider between the two winning holes 16 and the guide rail 12 than the diameter of the game ball 9. 3), and a game ball can pass between the guide rail 12 and the winning opening 16.
In a portion where the guide rail 12, the winning opening 16, and the game nail 17 are close to each other, there is a possibility that ball accumulation due to ball clogging occurs.

  Basically, in the portion that becomes the flow path of the game ball, the gap between the members such as the guide rail 12, the winning opening 16, the game nail 17 and the like is wider than the diameter of the game ball, so the ball is blocked by one game ball. When a plurality of game balls flow down in close proximity, the plurality of game balls come into contact with each member, and the game balls come into contact with each other, so that the load and frictional force of each game ball can be reduced. When the balance is achieved, a state where the game ball cannot pass between the members (ball clogging) occurs.

  When game balls are further stacked on top of the game balls that are packed, if the game balls that were initially packed are not broken, the friction force increases due to the load of the stacked game balls, and the ball blocks become solid. There is a possibility. Therefore, if a plurality of game balls are stopped at intervals between the above-described members with a magnet, a ball pool may be easily formed.

  2 and 3 from a location away from the guide rail 12 because the guide rail 12 also contributes to the generation of a ball pool when the winning opening 16 and the game nail 17 are in the vicinity of the guide rail 12. There is a high possibility that a ball pool will occur. If the distance between the two members is less than twice the diameter of the game ball, ball clogging is likely to occur. For example, the shortest distance between the winning opening 16 protruding from the board surface of the game board 3 and the guide rail 12 is the game. If the diameter is less than twice the diameter of the sphere, there is a high possibility that sphere clogging will occur at this portion.

  In this example, the horizontal line a passing through the upper end (height position of the opening) of the upper winning port 16 among the winning ports 16 arranged side by side along the guide rail 12 as described above and the guide rail 12. The ball pooled within a range X from the intersection point to the intersection point of the straight line b passing through the right side of the winning port 16 below the winning port 16 (the side portion opposite to the upper winning port 16) and the guide rail 12. A reflective optical sensor unit 20 (hereinafter abbreviated as a sensor unit 20) as a game ball detection means is provided on the guide rail 12 (14) so as to detect at least one of the game balls.

The sensor unit 20 is provided in a portion in the above-described range X of the guide rail 12 (14). In this embodiment, as a measure against the fact that a game ball can be easily won in both the winning holes 16 by clogging the balls between the left winning hole 16 and the right winning hole 16, the position X is approximately at the center of the range X. A sensor unit 20 is installed.
Furthermore, preferably, within the range X of the guide rail 12 described above, the leftmost normal of the normals of the guide rail 12 that contacts the above-described winning opening 16 arranged side by side along the guide rail 12 and The sensor unit 20 is arranged in the portion of the guide rail 12 between the rightmost normal line.

The sensor unit 20 can detect a game ball passing between the guide rail 12 (14) and any one of at least two winning holes 16.
The sensor unit 20 includes a casing 21 that becomes a part of the guide rail 12 and a reflective optical sensor (not shown) provided therein. The casing 21 has a frequency band in which a portion through which light from a light emitting element described later passes and a portion through which light reaches a light receiving element described later passes, and a frequency at which the light receiving element can receive light well. Light with the band can be transmitted. The frequency band of the light emitting element and the frequency band of the light receiving element overlap. Further, the entire top plate 22 of the casing 21 constituting the upper surface of the sensor unit 20 may be capable of transmitting the above-described light, or the entire casing 21 may be capable of transmitting the above-described light.

  The sensor unit 20 is attached to an attachment recess 19 for attaching the sensor unit 20 of the synthetic resin portion of the guide rail 12. The sensor unit 20 is attached to the mounting recess 19 of the guide rail 12 and is in a state of filling the mounting recess 19, and a part of the surface A in which the upper surface of the sensor unit 20 faces the game area 7 side of the guide rail 12. Is configured. That is, the casing 21 of the sensor unit 20 constitutes a part of the guide rail 12. A connector is provided on the back surface of the sensor unit 20, and electrical connection is made between the sensor unit 20 and the gaming machine side by connecting to the connector 26 provided in the mounting recess 19. The connector 26 of the mounting recess 19 is connected to the control circuit board on the back surface B of the game board 3.

  Further, an engagement hole (engagement groove) 19a for engaging an engagement protrusion (engagement protrusion) 19b of the sensor unit 20 is provided at the bottom of the mounting recess 19 of the guide rail 12, and the sensor The sensor unit 20 can be fixed to the guide rail 12 by engaging the engagement protrusion 19b formed on the casing 21 of the unit 20 with the engagement hole 19a.

  The reflection type optical sensor arranged inside the casing 21 is directed in substantially the same direction, the light emitting element and the light receiving element are arranged side by side, and the light emitted from the light emitting element hits the object (game ball 9) and is reflected. In such a case, the reflected light is received by a light receiving element to detect the object.

  The reflective optical sensor outputs a signal to a control circuit board (for example, a main board or a sub board) on the back surface B side of the game board 3 when the amount of light received by the light receiving element exceeds a predetermined threshold value. It has become. The reflective optical sensor is inside the casing 21 constituting a part of the guide rail 12 as described above, and constitutes the upper surface of the casing 21 corresponding to the surface A facing the game area 7 side of the guide rail 12. The top plate 22 constitutes a part of the surface A facing the game area 7 side of the guide rail 12.

  The reflective optical sensor is arranged on the opposite side of the top area 22 of the casing 21 to the game area 7, that is, on the non-game area 27 side that is not the game area 7. The reflective optical sensor arranged on the non-game area 27 side is configured to detect the game ball 9 via the top plate 22 of the casing 21 that constitutes a part of the guide rail 12.

In the control circuit board, when a signal is input from the reflective optical sensor of the sensor unit 20, for example, a time during which the main process is repeated at a predetermined time interval, for example, in a real-time process in the control device for the main board or the sub board. While the signal continues to be input from the reflective optical sensor at every interval, the count value of the counter is counted up, and the input of the signal from the reflective optical sensor is interrupted before reaching the predetermined count value. The count value of the counter is reset.
The predetermined count value is a count value in which the time required for counting up to the count value is a predetermined time of, for example, about 5 seconds to 10 seconds. When the count value reaches a predetermined count value without being reset halfway, the game ball stays between the range of the guide rail 12 and the winning slot 16 and the game nail 17. judge. In addition, the above-mentioned predetermined time is an example, and may be shorter or longer than that.

  That is, the control circuit board determines that a ball pool is formed and outputs a signal indicating the occurrence of the ball pool. This signal may be output to, for example, a management device of a game store, or may be output to a lighting device (warning light) of an island facility of a game store. In addition, the signal is used as an error signal in the control circuit board in the pachinko gaming machine 1 to temporarily stop the game in the pachinko gaming machine or turn on a part of various decorative lamps (LEDs) for the pachinko gaming machine. Etc.

  The signal output wiring from the sensor unit 20 to the control device is, for example, passed through the game board 3 at or near the sensor unit 20 (at the connector 26 described above) and on the back surface B of the game board 3. The game board 3 may be wired on the control device side, or the front F side of the game board 3 may be non-obstructed so as not to interfere with the launched game ball passing between the outer guide rail 13 and the inner guide rail 14. After wiring the portion of the game area 27, wiring from the side edge portion of the game board 3 to the control device on the back B side of the game board 3 may be performed. For example, a signal line that outputs the above-described signal may be wired along the surface of the guide rail 12 on the non-game area 27 side, and may be routed from the side edge of the game board 3 to the back surface B side of the game board 3.

  In this ball game machine, the guide rail 12 and the winning opening 16 where many game nails 17 are arranged around the opening are arranged close to each other, so that the ball pool is likely to occur. When a ball pool is generated by a magnet, the accumulated game ball can be detected by a reflective optical sensor. That is, even without using a magnetic sensor, it is possible to detect fraudulent acts by magnets, and the number of magnetic sensors for detecting fraudulent acts by magnets can be reduced.

  In addition, the sensor unit 20 including the reflective optical sensor can be arranged outside the game area on the front F side of the game board 3 (non-game area 27). That is, the number of sensors arranged on the back surface B of the game board 3 can be reduced. Thereby, the freedom degree of arrangement | positioning of each member in the game board 3 back surface B increases, and a design becomes easy. In other words, since the sensor can be arranged not on the back surface B of the game board 3 in which various members are arranged in a complicated manner but on the front surface F of the game board 3, the sensor can be easily arranged.

  In the above-described embodiment, the sensor unit 20 is attached to the surface A side of the game area 7 of the guide rail 12, but the sensor unit 30 is not attached to the guide rail 12 (14) as shown in FIG. It is good also as a structure attached from the surface Z side of the game area | region 27. FIG. In this case, a mounting recess 32 is provided in the surface Z of the guide rail 12 on the non-game area 27 side, and the mounting recess 32 and the reflective optical sensor unit 30 are mounted. The non-game area 27 of the guide rail 12 (14) is a guide path 15 for the launched game ball 9, and the game ball 9 passing through the guide path 15 may come into contact with the lower surface side of the sensor unit 30. Therefore, it is preferable that the lower surface of the sensor unit 30 is a surface (substantially flush surface) substantially along the surface Z on the non-game area 27 side of the guide rail 12. Further, when the lower surface of the sensor unit 30 protrudes toward the non-game area 27 of the guide rail 12, even if the game ball 9 contacts the sensor unit 30, the momentum of the game ball is kept as much as possible. Thus, it is preferable that the curved surface shape 28 (shown by a broken line) has no corner portion and has a small angle difference from the surface Z.

In addition, a slit 31 is provided in a portion of the mounting recess 32 of the guide rail 12 on the game area 7 side. The slit 31 penetrates from the game area 7 side to the mounting recess 32.
In the sensor unit 30, the light emitting element and the light receiving element are disposed so as to face the portion of the slit 31 that penetrates the mounting recess 32 when the sensor unit 30 is mounted in the mounting recess 32. In the sensor unit 30, the light emitting element and the light receiving element are exposed from the casing 33, and the game is performed from the sensor unit 30 on the non-game area 27 side of the guide rail 12 through the slit 31 of the guide rail 12. It is possible to detect the game ball 9 that passes between the winning opening 16 and the guide rail 12 on the region 7 side.

Further, the sensor unit 30 is also connected to the control device, and the ball pool can be detected as in the case of the sensor unit 20.
Further, although the game ball detecting means is the reflection type optical sensor units 20 and 30, a proximity sensor for detecting the game ball of the ball game machine may be used.

  Moreover, in the guide rail 12 of the game board 3 of the above-described embodiment, based on the game ball launch direction (for example, the upper left direction or the left direction) in the game ball launcher, the lower left part of the game board 3 A guide path 15 for a game ball that is fired immediately outside the inner guide rail 14 is formed.

Here, depending on the gaming machine, since the game ball is fired upward, the inner guide rail 14 and the guide path 15 may be separated in the lower left portion of the game board 3. In this case, since there is a wide space between the inner guide rail 14 and the guide path 15, there is sufficient space for placing a sensor as a game ball detection means, not a unitized sensor but a mounting type. It is also possible to dispose the substrate in a state where the sensor is mounted on the substrate.
In addition, as shown in FIG. 2, not only the lower left side of the game area 7 but also the lower right side may be provided with a winning opening 16 near the guide rail 12. The sensor units 20 and 30 may be arranged. In this case, it can be set as the structure similar to the above-mentioned embodiment except that right and left are reversed.

  As mentioned above, although embodiment which applied the invention made by this inventor was described, this invention is not limited by the description and drawing which make a part of indication of this invention by this embodiment. That is, it should be added that other embodiments, examples, operation techniques, and the like made by those skilled in the art based on this embodiment are all included in the scope of the present invention.
