  Therefore, as a countermeasure against such fraud, a magnetic sensor for detecting a magnet that illegally guides the game ball is provided on the game board, but it is available in the market used in the current game machine. A possible magnetic sensor has a relatively narrow detection range, so that it is necessary to provide a plurality of magnetic sensors to cover the entire gaming area, which increases the cost of the gaming machine.

  In addition, in an illegal act using a game ball wrapped around a game ball, etc., it is possible to guide the game ball to the prize opening by skillfully manipulating the game ball without guiding the game ball with a magnet. There is also a problem that there are many cases where it is not a fundamental solution just by providing the system.

Normally, the normal variation winning device 108 is in a closed state, and a game ball is not in a winning state. When the game ball passes through the normal symbol start gate 109, a general variation display game is executed, and when a win state occurs as a result of the general variation display game, the normal variation winning device 108 is converted to an open state and the game ball Will be easy to win.

  A game ball won in the start winning opening 107 or the normal variation winning apparatus 108 is detected by a start opening switch (not shown). A random number value is extracted according to the detection timing of the winning ball, and the random number value is stored as a start winning memory in the start storage area in the RAM of the game control device for a predetermined number of times (for example, a maximum of 4 times). The stored number of start winning memories is displayed on the display unit of the display device 103. The game control device plays a special figure fluctuation display game by the fluctuation display 120 based on the start winning memory. In parallel with this special figure variation display game, the effect control device uses the display device 103 to display a decoration special figure variation display game (hereinafter referred to as a variation display game unless otherwise specified) based on a command from the game control device. Call).

  When the random value at the time of detection of the winning ball at the start winning opening is a winning value, a specific result mode (special result mode) is derived from the display symbol as a result of the special figure variation display game, and a big hit state is obtained. As a result, from the closed state in which the game balls are not received to the open state in which the game balls are easily received until the special winning opening of the special variable prize winning device 110 is awarded for a predetermined time (for example, 30 seconds) or until a predetermined number of game balls are won. The player is given a privilege that it is converted and a lot of prize balls can be obtained.

  When there is a general-purpose winning memory, the game control device starts a general-purpose variable display game on the variable display unit 120 based on the general-purpose winning memory. That is, when the random number extracted when the game ball that has passed through the normal symbol start gate 109 is detected is a winning value, the normal symbol displayed on the variation display unit 120 stops in a winning state and enters a winning state. . At this time, the normal variation winning device 108 is converted so that the movable wing piece is largely opened for a predetermined time by energizing the solenoid, and the winning probability of the game ball at the starting winning opening is increased.

Thus, when the ball return regulating members 143A and 143B are rotated counterclockwise inside the stopper pieces 725a and 725b and the regulating pieces 143a and 143b on the front end side become vertical, the regulating pieces 143a and 143b are Restriction piece evacuation spaces 729a and 729b are formed so as not to protrude from the wall surface of the spherical confluence downstream 725.
As can be seen from FIG. 9, the second ball return regulating member 143B has its rotation shaft 728b disposed on the extension of the upper part of the ball detection sensor 141, so that the restriction piece 143b on the tip side is the ball detection sensor 141. The first ball return regulating member 143A is disposed at a position where the rotation shaft 728a is higher than the rotation shaft 728b by one ball, so that the first ball return restriction member 143A is located above the ball detection sensor 141. It is comprised so that it may protrude in the spherical confluence | merging downstream 725.

  As shown in FIG. 10 (A), in the spherical confluence 725 provided with the first restricting member attaching portion 727A and the second restricting member attaching portion 727B configured as described above, When the game ball flows in and comes into contact with the restriction piece 143a on the distal end side of the first ball return restriction member 143A, it flows downward while rotating the first ball return restriction member 143A counterclockwise with its weight. At this time, the inner diameter of the ball confluence lower path 725 is slightly larger than the diameter of the game ball, but the restriction piece 143a of the first ball return restriction member 143A is accommodated in the restriction piece retreat space 729a, so that the game ball Downflow is allowed.

  Thereafter, as shown in FIG. 10B, when the game ball starts to enter the detection area DA of the ball detection sensor 141 and moves until the center of the ball is positioned below the tip of the first ball return regulating member 143A, The restriction piece 143a on the front end side starts to rotate clockwise by the weight of the metal pin 144A on the rear end. When the lower end of the game ball flows down to a position where it comes into contact with the restriction piece 143b on the front end side of the second ball return restriction member 143B, the first ball return restriction member 143A is completely at the original position of the restriction piece 143a on the front end side. Return to rotation.

  In this state, the game ball comes into contact with the front end surface of the regulation piece 143a, so that even if the game ball is wound around the game ball and pulled upward, it is blocked by the regulation piece 143a and moves in the return direction. Absent. The position where the lower end of the game ball contacts the restriction piece 143b on the tip side of the second ball return restriction member 143B is a position where the lower end of the game ball enters the detection area DA of the ball detection sensor 141. is there. In addition, in a state where a part of the game ball has entered the detection area DA of the ball detection sensor 141, light from the light emitting element of the ball detection sensor 141 is blocked by the game ball and does not reach the light receiving element. Is detected as having a ball. Even if a part of the game ball enters the detection area DA of the ball detection sensor 141, if the sensor ball returns upward, the sensor will be in a non-detection state, but as described above, by the restriction piece 143a of the first ball return restriction member 143A By preventing the return of the game ball, it is possible to prevent the same game ball from being detected again.

  Thereafter, when the game ball further flows down and the center of the ball reaches the center of the detection area DA of the ball detection sensor 141 as shown in FIG. 11A, the weight of the second ball return regulating member 143B is counteracted by its weight. By turning clockwise, the restriction piece 143b at the tip is in a state of being retracted from the flow path to the restriction piece retracting space 729b. Then, when the upper end of the game ball flows down to the position where it comes out of the detection area DA of the ball detection sensor 141, it rotates in the clockwise direction by the weight of the metal pin 144B at the rear end, as shown in FIG. In the second ball return regulating member 143B, the regulating piece 143b on the front end side returns to its original position. At this time, the ball detection sensor 141 is in a non-detection state. In this state, even if the game ball is wound around the game ball and pulled, the restriction piece 143b moves the game ball in the return direction. It is prevented and the sphere detection sensor 141 can be prevented from entering the detection state again.

  As described above, in this embodiment, the first ball return regulating member 143A and the second ball return regulating member 143B are provided, so that a person who intends to cheat winds the game ball and wins a prize. With the same game ball, the game balls are pulled up or loosened in the vicinity of the detection area by winning the mouths 411, 412, and 413 and then pulling or loosening the game balls while flowing down to the position of the ball detection sensor 141. Even if the detection signal is generated many times, it can be effectively prevented.

  From the above description, in the present application, in the present application, a winning opening where a game ball flowing down a gaming area defined on the surface of the game board can win, a ball flow path for flowing down the winning game ball in the winning opening, A game machine comprising a ball detection unit capable of detecting a game ball flowing down the ball flow down path, and detecting a game ball set in the ball detection unit and flowing down from the ball flow down path to the ball detection unit And a restricting member that is provided corresponding to the ball detecting unit and that can restrict a game ball that has entered the ball detecting area from re-entering the ball detecting area. It can be seen that the present invention is included.

  And according to this invention, the game ball which entered the ball detection area is provided with the regulation member which can regulate that the game ball which entered the ball detection area re-enters the ball detection area. Since it is not possible to re-enter the ball detection area, it is possible to effectively prevent a so-called fraudulent act called fishing line goto.

  In addition, the gaming machine of the above embodiment includes an entry permission state that allows a game ball that has flowed down the ball flow path to enter the ball detection area of the ball detection sensor, and a game ball that has entered the ball detection area is upstream. A first restricting member that can be converted into a reversing restricted state that restricts the return to the state, a movement allowing state that allows a game ball that has entered the ball detecting area to move downstream, and a downstream side from the ball detecting area And a second restricting member that can be converted into a re-entry restriction state that restricts the re-entry of the game ball that has moved to the ball detection area.

  In addition, by providing the first restricting member and the second restricting member, the gaming machine according to the present embodiment is illegal such that the game ball is moved up and down between the ball detection area and the upstream thereof and sensed many times. While the act can be prevented by the first restricting member, the second restricting member can prevent an illegal act such that the game ball is moved up and down between the ball detection region and the downstream thereof and sensed many times. It becomes like this.

  Furthermore, in the gaming machine of the above embodiment, the first restricting member and the second restricting member are centered on a rotating shaft set in a direction crossing the ball flow down path at a position deviated from the ball flow down path. A bearing part pivotally mounted on the bearing part, and a regulation part that extends from the bearing part in a direction perpendicular to the pivoting axis and is movable forward and backward in the ball flow path, The restricting portion receives the pressing force of the game ball from the upstream side and retreats from the ball flow down path to convert to the entry allowable state or the forward movement allowable state, while the restricting portion of the game ball from the upstream side By being released from the pressing force, the ball protrudes into the ball flow down path and is converted into the reverse return restricted state or the re-entry restricted state.

  And by having such a structure, the gaming machine according to the present embodiment has an entry permission state or a forward movement permission state and a reverse movement restriction state, depending on the pressing force that the first restriction member and the second restriction member receive from the game ball. Since the state is changed to the re-entry restriction state, it is not necessary to separately provide a drive source for the state change.

  Next, a more desirable structure of the above embodiment will be described. Specifically, as shown in FIG. 11 (B), the return piece 143b of the second ball return restriction member 143B completely protrudes into the ball merging downstream 725 (the extended portion 144b becomes the stopper piece 725b). The angle θ formed by the restriction piece 143b and the inner wall surface of the ball confluence downstream 725 becomes 45 degrees in the state where the contact piece is in a horizontal state), and the center of the game ball in contact with the tip of the restriction piece 143b and the restriction The dimensions and mounting positions of each component are designed so that the center line of the piece and the second rotation shaft 728b are aligned on a straight line. As a result, when the tees wound around the game ball are pulled upward, the second rotating shaft 728b receives the ball pressure applied to the restricting piece 143b, thereby avoiding bending stress on the restricting piece 143b. can do.

  Therefore, if the second rotating shaft 728b is formed of a material having high strength such as metal, even if the restricting piece 143b is formed of a material that is relatively easily deformed or damaged such as plastic, the deformation or damage is prevented. There is an advantage that can be. The same applies to the structure of the first ball return regulating member 143A. Further, even if the restricting pieces 143a and 143b are configured so as to be in a horizontal posture in the return state, the return of the game ball can be prevented, but the restricting piece 143a in the return state as in the above embodiment. , 143b protrudes obliquely downward, the rotation angle of the restriction pieces 143a, 143b at the time of return can be reduced and returned quickly, and the return amount of the game ball can also be reduced.

  Therefore, in the gaming machine of the above-described embodiment, the first restriction member and the second restriction member are located on the downstream side of the bearing portion in the reverse return restriction state or the re-entry restriction state. It is arranged in the ball flow downway, and is set so as to cross the ball flow downway obliquely toward the downstream side so as to receive the pressing force of the game ball from the upstream side of the ball flow downway.

  In the gaming machine of the above-described embodiment, the restriction portion is disposed in the ball flow downstream on the downstream side of the bearing portion, and the ball flow downstream so as to receive the pressing force of the game ball from the upstream side of the ball flow downstream. Is set so as to cross diagonally toward the downstream side, so that the first restricting member or the second restricting portion is in a state where the restricting portion is orthogonal to the ball flow downway in the reverse return restricting state or the re-entry restricting state. Since the amount of rotation when the restricting member changes its state is small, even if it is converted to the entry-permitted state or the forward movement-permitted state, it can quickly return to the reverse-return restricted state or the re-entry restricted state. Can be effectively prevented. Further, the extended end portion that receives the pressing force of the game ball from the upstream side is less likely to be damaged by the impact at the time of the game ball collision.

  Furthermore, in the gaming machine of the above-described embodiment, when the restriction portion moves toward the upstream side in the ball flow downway in the reversal restriction state or the re-entry restriction state, the game ball is on the downstream side. The contact portion is set closer to the bearing portion side than the center of the ball flow downstream as a portion protruding to the ball flow lower passage together with the restriction portion, and contacted from the downstream side The shape is set to transmit the pressing force of the game ball toward the rotation shaft.

  Thus, since the contact part provided in the control part is set so that it may be located in the bearing part side rather than the center of a ball flow downway, the gaming machine of the above-mentioned embodiment has the 1st control member or the 2nd. Since the length of the restricting portion of the restricting member is short, it is difficult to break. Further, the amount of rotation when the first restricting member or the second restricting member changes the state can be further reduced, and no force in the turning direction acts even if the contact portion receives the pressing force of the game ball. And can effectively prevent fraud.

Next, a second embodiment of the present invention will be described with reference to FIGS. The second embodiment is different from the first embodiment described above in the configuration of the ball return regulating member and the structure of the sphere detection sensor 141 to be used. In the second embodiment, as shown in FIG. 12, there is one restricting member attaching portion, and the restricting member attaching portion 727 is rotatably engaged with the rotating shaft 728 and the rotating shaft 728. A reverse fan-shaped ball return regulating member 143 is provided, and a slit 725c through which the ball return regulating member 143 can enter / retreat into the flow path is formed on the wall surface of the spherical confluence downstream 725 near the rotating shaft 728. Has been.
The ball return restricting member 143 includes a cylindrical bearing portion 143c that is rotatably engaged with the rotating shaft 728 and a fan-shaped restricting piece 143d, and the restricting piece 143d is formed in a frame shape to reduce the weight. In addition, one of the arm portions extending radially from the bearing portion 143c acts as a ball restricting portion, and the other acts as a weight. A metal piece serving as a weight may be embedded on the side of the regulating piece 143d far from the ball regulating portion.

  The ball detection sensor 141 used in this embodiment has a structure similar to a mechanical switch called a micro switch, and an opening 141A (through which a game ball can pass through the tip of a main body having a shape similar to a domino basket. Equivalent to a sphere detection area) is formed, and the actuator 141B protrudes into the opening 141A. However, the configuration of the restricting member attaching portion 727 may be the same as that of the restricting member attaching portion 727A in the first embodiment. The gist of the present embodiment is that the actuator is also used as a ball return regulating member. For this purpose, the following devices are devised.

  Specifically, as shown in FIG. 12 (B), the sensor mounting portion 726 is configured as a storage recess having a height substantially the same as the thickness of the ball detection sensor 141 at the lower end of the left collective flow path member 702. On the bottom wall of the storage recess (726), a drop-off restricting claw 726a having a notch parallel to both sides and having a serrated projection formed at the tip is provided, and the ball detection sensor 141 is placed in the storage recess (726). It is configured so that it can be mounted with one touch, and the mounted ball detection sensor 141 can be firmly fixed by the drop-off restricting claw 726a. By having such a configuration, when the actuator is also used as a ball return regulating member, the ball detection sensor 141 shifts due to the ball pressure acting on the actuator 141B, and the detection timing is likely to change or break easily. Can be prevented.

  FIG. 13 shows a detailed structure of the sphere detection sensor 141 used in the present embodiment. As shown in FIG. 13B, one end of the actuator 141B is rotatably mounted on the edge of the opening 141A by a rotation shaft 141D, and the ball detection sensor 141 has an axial direction in the sensor body. And a compression spring 141F that presses the plunger 141E toward the opening 14A. The tip of the plunger 141E abuts on the back surface of the actuator 141B, and this is the front, that is, the center of the opening 14A. It is comprised so that it may press to the side.

  In addition, the actuator 141B is attached to the opening 141A so as to be inclined downward at an angle of about 45 degrees, and a retracting space 141G for the actuator 141B is provided on the inner wall of the opening 141A. Further, a stopper portion 141H is provided at the upper portion of the retracting space 141G and at the edge portion of the opening 141A to restrict the actuator 141B from rotating counterclockwise by 45 degrees or more. Although not shown in the figure, the sensor body includes an electrical contact that is opened and closed by the movement of the plunger 141E and a circuit that generates a signal corresponding to the open / closed state of the contact. The signal can be transmitted to the game control device via the connector 141c.

  FIG. 14 shows a state in which the sphere return regulating member 143 and the sphere detection sensor 141 are mounted on the sphere confluence lower path 725 at the lower end of the left collective flow path member 702. As shown in the figure, the ball return regulating member 143 is configured such that a part (regulating portion) of the regulating piece 143d extends from the slit 725c in a state where the bearing portion 143c is engaged with the rotating shaft 728. The balance is set so as to protrude inside. Further, a stopper portion 725c for restricting the rotation range of the ball return regulating member 143 is provided diagonally to the upper right of the rotation shaft 728, and the ball return regulating member 143 moves counterclockwise by the game ball flowing down. Further rotation is restricted by the rear end of the restricting piece 143d coming into contact with the stopper portion 725c when it is turned.

  Further, the ball return restricting member 143 is positioned at the position of the rotation shaft 728 so that the lower end of the restriction piece 143d is located near the tip of the ball detection sensor 141 in a state where the bearing portion 143c is engaged with the rotation shaft 728. The size of the restriction piece 143d is set. Next, operations of the ball return regulating member 143 and the ball detection sensor 141 configured as described above will be described with reference to FIGS. 15 and 16.

  As shown in FIG. 15 (A), when a game ball flows into the ball confluence lower path 725 and comes into contact with the restriction piece 143c of the ball return restriction member 143, the ball return restriction member 143 is rotated counterclockwise by its weight. Flow down while moving. At this time, the inner diameter of the ball confluence downstream 725 is slightly larger than the diameter of the game ball, but the flow of the game ball is allowed by the retraction of the restriction piece 143c of the ball return restriction member 143 from the flow path. The

  Thereafter, as shown in FIG. 15B, when the game ball enters the opening 141A of the ball detection sensor 141 and moves to a position where it comes into contact with the actuator 141B, the regulating piece 143c of the ball return regulating member 143 is watched by its weight. Begins rotating in the direction of rotation. Further, the actuator 141B is pushed by the game ball and the plunger 141E moves backward to rotate in the clockwise direction and move backward to the retreat space, thereby allowing the game ball to flow down. Then, as shown in FIG. 16A, when the game ball flows down to the position where the actuator 141B is actuated, the first ball return regulating member 143 returns the regulating piece 143c to its original state completely. In this state, even if the game ball is wound around the game ball and pulled upward, it is blocked by the restriction piece 143c and does not move in the return direction. This prevents the game ball from returning and being detected again.

  Thereafter, when the game ball further flows down and the game ball comes to a position where the center of the game ball is lower than the tip of the actuator 141B of the ball detection sensor 141 as shown in FIG. 16B, the compression spring 141F. The restoring force of the plunger 141E is pushed forward, that is, toward the center of the downflow path to return the actuator 141B to the original state (a state inclined by 45 degrees), and the contact of the ball detection sensor 141 is “open”, that is, a non-detection state. In this state, the tip of the actuator 141B is in contact with the upper end of the game ball, and the actuator 141B is restricted from turning 45 degrees or more by the stopper portion 141H. Therefore, the return direction of the game ball by the actuator 141B It is possible to prevent the sphere detection sensor 141 from entering the detection state again due to being prevented from moving to.

As described above, in this embodiment, the ball return restricting member 143 and the actuator 141B of the ball detection sensor 141 can prevent the game ball from moving in the return direction. Tegs are wrapped around the ball and awarded to the winning openings 411, 412 and 413. Further, the game ball is drawn down and loosened while the game ball is made to flow down to the position of the ball detection sensor, and the game ball is moved up and down in the vicinity of the detection area. Even if the detection signal is generated many times by the same game ball, it can be effectively prevented.
In addition, the shape of the actuator 141B in the present embodiment is designed to have a contact portion (contact surface) on which the game ball contacts from the downstream side like the return regulating member 143B shown in FIG. Thus, a configuration may be adopted in which the rotating shaft 141D can receive the ball pressure generated when trying to return the game ball.

  As described above, in the gaming machine of the second embodiment, the ball detection unit includes the second restricting member as an actuator, and the contact state changes as the second restricting member changes from the protruding state to the retracted state. It will be configured as a mechanical sensor. As described above, in the gaming machine of the second embodiment, the second regulating member that regulates the reversal of the game ball also serves as the actuator of the mechanical sensor, so that the arrangement efficiency of the ball detection unit and the regulating member is increased. The number of parts is reduced and assembly work is simplified.

Next, another embodiment of the present invention will be described with reference to FIGS. FIG. 17A shows a third embodiment. In the third embodiment, a non-contact type magnetic proximity switch is used instead of the photoelectric sensor as the ball detection sensor 141 in the first embodiment described above.
The magnetic proximity switch is a non-contact type magnetic proximity sensor that detects a game ball using a phenomenon in which a magnetic field changes when a metal comes close to a coil. In FIG. It arrange | positions so that it may face the flow path of the downflow path 725, the coil is arrange | positioned in the site | part, and the detection circuit connected to the coil is incorporated in the inside of a main body. In this magnetic proximity sensor, when the game ball passes through the magnetic flux range MA of the coil, the magnetic field of the coil changes and the impedance of the coil changes. Therefore, it is possible to detect that the game ball has passed from the change.

  FIG. 17B shows a fourth embodiment. In the fourth embodiment, instead of the fan-shaped ball return regulating member 143 in the second embodiment described above, the regulating piece 143a, the extending portion 144a, and the metal pin 144A serving as a weight in the first embodiment are provided. The “he” -shaped ball return regulating member 143A is used. Correspondingly, a stopper 725a similar to that of the first embodiment is provided on the wall surface of the spherical confluence downstream 725. Since other configurations and operations are the same as those described in the first embodiment, the same or corresponding parts and portions are denoted by the same reference numerals and description thereof is omitted.

  FIG. 18 shows a fifth embodiment. In the fifth embodiment, the main body case of the sphere detection sensor 141 is formed in a substantially L shape. In the first embodiment, the first sphere return regulating member 143A and the first sphere return regulating member 143A provided on the sphere merging downstream 725 side are arranged. The two-ball return regulating member 143B is provided integrally with the main body case of the ball detection sensor 141. As in the first embodiment, the sphere detection sensor 141 is a photoelectric sensor (photo interrupter) including a light emitting element and a light receiving element that face each other. Since other configurations and operations are the same as those described in the first embodiment, the same or corresponding parts and portions are denoted by the same reference numerals and description thereof is omitted.

  Although the invention made by the present inventor has been specifically described based on the embodiment, the embodiment disclosed herein is merely an example and is not restrictive. For example, in the above embodiment, the two ball return regulating members are both configured as means for prohibiting the movement of the game ball in the direction opposite to the flow-down direction. If movement is detected, a restricting member (shutter) that prohibits movement in the downstream direction may be provided, and re-entry into the detection area may be prohibited.

  Further, in the above-described embodiment, the case where the countermeasure against fraud (fishing line goto) with respect to the winning hole is applied to the left winning hole unit 140, but it may be applied to the start opening unit 130 and the right winning hole unit 150. In the above embodiment, an example is shown in which a photoelectric sensor, a microswitch sensor, and a magnetic proximity switch are used as the sphere detection sensor 141. However, the present invention can also be applied to the case where other types of sensors and switches are used. it can.

  Furthermore, in the above description, the case where the present invention is applied to a pachinko gaming machine has been described as an example. However, the present invention is not limited to a pachinko gaming machine, and other game balls such as an arrangement ball gaming machine and a sparrow ball gaming machine are used. It can also be applied to other game machines.
