  When the game ball 23 is launched by a ball launching device (not shown), the game ball 23 travels along the outer rail 26 a of the rail decoration portion 26 and reaches the upper part in the game area 16. Thereafter, the game ball 23 moves along a plurality of passing trajectories, some moves to the right along the outer rail 26 a of the rail decoration portion 26, and some moves inside the game area 16 while colliding with the game nail 27. , And a certain thing flows into the normal winning opening 28 to trigger the payout of a certain number of prize balls, and a certain thing is positioned at the lowermost part in the game area 16 without flowing into any of the winning devices. It flows into the out port 30 and is discharged to the outside of the pachinko machine 2 as an out ball.

  When the game ball 23 flows into the start winning opening 29 during the symbol variation game, the display symbol 7c of the effect display device 7a starts rotating display (the first special game lottery) due to the inflow. If 7c is stopped and displayed with a predetermined symbol (for example, “7, 7, 7”), a big hit (first special game; hereinafter referred to as symbol fluctuation big hit) occurs in the symbol variable game. Then, the special winning opening 31 is opened to accept a large amount of winning balls, and a large amount of winning balls are paid out to the ball tray 14.

  Subsequently, the outlet unit U according to the first embodiment will be described with reference to the drawings. FIG. 3 is a front view of the game board 6 of the pachinko machine 2. The game board 6 is held by the front frame 9 of the pachinko machine 2 and is exposed to the front surface of the pachinko machine 2 by opening the glass frame 12 forward.

  In FIG. 3, only main parts for explaining the first embodiment are shown, and a windmill 25, a game nail 27, winning holes 28, 29, 31, which are arranged in the game area 16 on the game board 6, are shown. Illustration of the gate 33 and the like is omitted. In addition, the code | symbol 31a in FIG. 3 is the attachment hole for opening the big prize opening 31 formed in the game board 6 for the big prize opening 31 attachment.

  An out port unit U is attached to the game board 6. The out port unit U has a rail decoration portion 26 and an out port portion 30 and is generally configured. An inner rail 24 is also attached to the game board 6. As shown in FIG. 3, the inner rail 24 and the rail decoration portion 26 have a generally arc shape on the inner side, and are opposed to each other on the left and right sides with the out mouth portion 30 in between. The inner rail 24 and the rail decoration portion 26 surround a substantially circular area, and the outer periphery of the game area 16 is configured.

  When the game ball 23 that has flowed into the game area 16 from the outside of the inner rail 24 (the left side in FIG. 3) does not win any of the winning holes, it is guided by the inner rail 24 or the rail decoration 26 and the out mouth part. It flows into 30.

  FIG. 4 is an external perspective view of the out port unit U. FIG. FIG. 5 is an enlarged exploded view showing the main part of the outlet unit U in an enlarged manner. A guide slope 26 b for guiding the game ball 23 to the out mouth portion 30 is formed in a lower portion of the rail decoration portion 26. An inflow port 40 is formed so as to be connected to the guide slope 26b.

  The inflow port 40 is located in front of the out port portion 30 and allows the game ball 23 that has rolled on the guide slope 26 b to flow into the out port portion 30. FIG. 6 is an enlarged front view of the vicinity of the inflow port 40. In FIG. 6, the vicinity of the inlet 40 is viewed obliquely from the front and slightly above. As will be described later, the out port 30 includes a plurality of (two in the first embodiment) counting sensors 41 arranged side by side. The counting sensor 41 counts the number of game balls 23 flowing into the out port 30 and transmits counting information to the main control board 34. Each counting sensor 41 has a passage hole 41 a for allowing the game ball 23 to pass therethrough. The passage hole 41a has, for example, a circular shape having a larger diameter than the diameter of the game ball 23.

  For example, the count information from the count sensor 41 may be transmitted toward the main control board 34 and then sent from the main control board 34 to the effect control board. On the main control board 34 or the effect control board, the sum of the total number of out balls counted by the counting sensor 41 and the total number of winning balls won in each winning opening 28, 29, 31 is determined by the launch unit. Compared to the number of game balls fired.

  When fraud is not performed, the sum of the out ball and the winning ball and the number of the game balls to be fired should substantially match. However, when the total number of out balls and winning balls is larger than the number of game balls to be fired, for example, a thread hanging goto (a ball is connected to a game ball and fired, and the thread is operated to receive a sensor for a winning mouth. By repeatedly putting in and out game balls in the vicinity, it is possible to determine that an illegal act such as an illegal act of illegally acquiring a large number of prize balls. In that case, the effect control means can display an error on the effect display device 7a, notify an error by blinking a lamp as the decorative member 32, or generate a warning sound from the speaker.

  Further, the count information by the count sensor 41 may be transmitted from the main control board 34 to the hall computer of the gaming machine hall via the external output terminal board 39, for example. In the hall computer, an error display can be performed on the display screen of the hall computer by comparing the sum of the number of out balls and the number of winning balls and the number of game balls to be launched, as described above. Hall clerk can quickly detect fraud.

  The inflow port 40 is formed asymmetrically in front view with respect to the passage hole 41a in one counting sensor 41. That is, the inflow port 40 has a guide slope 26b and a bottom surface 26c that is one step lower than the guide slope 26, and is gently connected by the slope, and as a result, has a right shoulder 26d and a left shoulder 26e.

  In FIG. 6, the right shoulder 26d is located at an obliquely lower right front position with respect to the passage hole 41a of the right counting sensor 41. Therefore, the inlet 40 is asymmetric with respect to the right counting sensor 41. Yes. That is, the shape of the left and right inlets 40 is different from the passage hole 41a of the right counting sensor 41 (the height positions of the left and right inlets 40 are different).

  Similarly, in FIG. 6, the left shoulder 26e is located at an obliquely lower left front position with respect to the passage hole 41a of the left counting sensor 41. Therefore, the inlet 40 is asymmetric with respect to the left counting sensor 41. It has become. That is, the shape of the left and right inlets 40 is different from the passage hole 41a of the left counting sensor 41 (the height positions of the left and right inlets 40 are different).

  Thus, since the height position of the inflow port 40 is different on the right side and the left side with respect to the passage hole 41a in one counting sensor 41, in the unlikely event, two game balls 23 are lined up in the passage hole 41a. Even when trying to inflow, the game balls 23 exert unbalanced stresses on each other, and the ball clogging hardly occurs. As a result, the clogging is prevented by the left-right asymmetry of the inflow port 40.

  FIG. 7 is an enlarged view of the out port portion 30 in the out port unit U. FIG. (A) shows a front view and (b) shows an external perspective view.

  The out port portion 30 is disposed behind the inflow port 40 in the rail decoration portion 26 so that the two passage holes 41 a face the inflow port 40. The out mouth part 30 includes two counting sensors 41 arranged side by side on the left and right, a guide surface part 42 arranged in front (upstream side) of the counting sensor 41, and a guide arranged behind (downstream side) the counting sensor 41. The passage 45 (see FIG. 9) is generally configured.

  The counting sensor 41 is a sensor for counting the number of game balls 23 that have flowed from the inflow port 40. For example, a non-contact passage sensor such as a capacitance type or a magnetic type is used as the counting sensor 41, and a detection signal is output every time the game ball 23 passes through the passage hole 41a. In the outlet unit U, two counting sensors 41 are arranged side by side on the left and right. Since the number of game balls 23 is counted by the plurality of counting sensors 41, even when there are a large number of out balls, accurate number counting is possible without erroneous detection or detection omission.

  In addition, since the number of game balls 23 flowing into the out mouth portion 30 is detected, a prize ball is illegally obtained by connecting a thread or the like to the game ball 23 and taking it into and out of the winning openings 28, 29, 31 and the like. It is possible to effectively prevent the so-called thread hanging goto action to be acquired. That is, the total number of the game balls 23 won in each of the winning openings 28, 29, 31 and the number of the game balls 23 counted by the counting sensor 41 is substantially equal to the number of the game balls 23 launched per unit time. Based on whether or not they match, the presence or absence of the thread hanging action can be determined.

  When a plurality of counting sensors 41 are arranged, of course, the total number of game balls counted by the plurality of counting sensors 41 is the number of out balls. In addition, the out ball and the winning ball won in each winning opening are joined on the back side of the game board 6 and discharged to the outside of the pachinko machine 2, but this counting sensor 41 is It is arranged on the upstream side of the merging position with the winning ball, and the number of out balls before merging with the winning ball is counted.

  The guide surface portion 42 is disposed upstream of the counting sensor 41 and downstream of the inflow port 40, that is, at a position sandwiched between the counting sensor 41 and the inflow port 40, and the game ball 23 (out) flowing into the inflow port 40. Sphere) is guided to the passage hole 41a. Two openings are formed in the guide surface portion 42 corresponding to the respective passage holes 41a of the two counting sensors 41, and each opening has an opening width widening toward the upstream side (that is, a funnel shape). The guide surface 43 is an inclined surface or a curved surface.

  FIG. 8 is a cross-sectional view of the out mouth portion 30 taken along the line XX in FIG. In the first embodiment, two left and right guide surfaces 43 are formed corresponding to the two left and right passage holes 41a. Of the guide surface 43 corresponding to the right passage hole 41a, the right curved surface is the right outer surface 43a and the left curved surface is the right inner surface 43b. Of the guide surface 43 corresponding to the left passage hole 41a, the right curved surface is the left inner surface 43c and the left curved surface is the left outer surface 43d.

  As shown in FIG. 8, the right outer surface 43a and the right inner surface 43b have different radii of curvature. The left inner surface 43c and the left outer surface 43d have different radii of curvature. Furthermore, the right inner surface 43b and the left inner surface 43c have different radii of curvature. By comprising in this way, the following two effects are exhibited.

  That is, the first is that the position of the joining ridge line 44 where the right inner surface 43b and the left inner surface 43c join is displaced from the center position of the two passage holes 41a due to the difference in the radius of curvature between the right inner surface 43b and the left inner surface 43c. It is an effect by having. Specifically, the position of the joint ridge 44 is close to the left passage hole 41a. As a result, the number of game balls 23 flowing into the right counting sensor 41 and the number of game balls 23 flowing into the left counting sensor 41 are not equal. Due to the difference in ease of inflow into the left and right counting sensors 41, the occurrence of clogging in the vicinity of the guide surface portion 42 is prevented.

  The second effect is that an unbalanced stress is applied to the game ball 23 about to flow into the counting sensor 41 due to a difference in curvature radius between the right outer surface 43a and the right inner surface 43b. Specifically, for example, as shown by a broken line in the figure, a case is assumed in which two game balls 23a and 23b are arranged side by side toward the right counting sensor 41 almost simultaneously. The right game ball 23a contacts the right outer surface 43a, the left game ball 23b contacts the right inner surface 43b, and the left and right game balls 23a, 23b also contact each other.

  However, since the radii of curvature of the right outer surface 43a and the right inner surface 43b are different, the stress acting on the right game ball 23a and the stress acting on the left game ball 23b become unbalanced. The stress being unbalanced means that the state and / or strength of a plurality of stresses applied is different or is not a target, resulting in an unbalanced state. As a result, the two game balls 23 a and 23 b smoothly flow toward the counting sensor 41 on the right side without causing a ball clogging in the vicinity of the guide surface 43. The same effect can be obtained by the difference in curvature radius between the left inner surface 43c and the left outer surface 43d corresponding to the left counting sensor 41.

  The guide passage 45 is disposed behind (downstream) the counting sensor 41 and guides the game ball 23 to the discharge path 46. FIG. 9 is a perspective view of the vicinity of the out port 30 as viewed obliquely from the rear. In FIG. 9, the vicinity of the out mouth part 30 is seen from the diagonally left rear. The guide passage 45 for guiding the game ball 23 after passing through the passage hole 41a communicates with the downstream side of the counting sensor 41, and the discharge path 46 communicates with the downstream side of the guide passage 45. Are discharged from the discharge path 46 to the outside of the pachinko machine 2. In the middle of the discharge path 46, the winning balls that have won the winning openings 28, 29, and 31 and the out balls are merged.

  The guide passage 45 has inclined ribs 47 corresponding to the counting sensors 41 on the lower surface of the passage. The inclined rib 47 receives the game ball 23 on its upper surface and rolls it to the discharge path 46, and is disposed at a position immediately downstream of the passage hole 41a. The rib height on the counting sensor 41 side (upstream side) is high and the rib height on the discharge path 46 side (downstream side) is low. Of course, the rib height position on the upstream side is the outer circumference of the passage hole 41a. The position is lower than the lower end position. The game ball 23 having passed through the passage hole 41a is accelerated and guided toward the rear discharge path 46 quickly and smoothly. Therefore, it is effectively prevented that the game ball 23 after passing through the passage hole 41a flows backward due to some external factor such as vibration and is detected again by the counting sensor 41 (so-called false detection by chattering). .

[Embodiment 2]
Next, Embodiment 2 of the present invention will be described. FIG. 10 is an external perspective view of the out port unit U of the pachinko machine 2 according to the second embodiment, and FIG. 11 is a partially enlarged cross-sectional view of the out port unit U cut along a cross section YY in FIG. . The cross section YY is a plane (plane P) that passes through a substantially diameter position in the vertical direction of the left passage hole 41a out of the two passage holes 41a and extends in the front-rear and up-down directions. In FIG. 11, the vicinity of the inlet 40 and the outlet 30 is partially enlarged. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the outlet unit U, the bottom surface 26c of the inlet 40 has a plurality of inclination angles in the front-rear direction (depth direction). For example, as shown in FIG. 11, at least in the cross-section YY, it has a plurality of inclination angles in the front-rear direction. Similarly, although not shown, the right passage hole 41a also has a plurality of inclination angles in the front-rear direction at a substantially diameter position in the vertical direction (that is, a position corresponding to a substantially lowest point on the circumference of the passage hole 41a). have.

  As described above, the portion having a plurality of inclination angles in the front-rear direction may be present at least in the vicinity of the substantially diameter position in the vertical direction of the passage hole 41a, but is sandwiched between the right shoulder portion 26d and the left shoulder portion 26e. You may have several inclination angles in the front-back direction over the bottom face 26c whole region.

  In the second embodiment, the plurality of inclination angles are two kinds of inclination angles, and as shown in FIG. 11, an inclination angle of 10 ° and an inclination angle of 5 ° with respect to the horizontal plane. A gentle slope 51 having an inclination angle of 5 ° is formed on the side (front side) far from the passage hole 41a of the out mouth portion 30, and a steep slope 52 having an inclination angle of 10 ° is formed on the near side (rear side). Yes. The gentle slope 51 and the steep slope 52 are connected in the front-rear direction, and the connecting portion 53 may be bent, or may be R-treated and smoothly connect the gentle slope 51 and the steep slope 52. Good.

  Of course, the plurality of inclination angles are not limited to two types, and may be three types or more. The tilt angle may be gradually changed in a stepless manner (that is, in a curved surface shape). However, it is preferable that the inclination angle on the rear side is steeper than the front side. Also in the second embodiment, the front side is a gentle slope 51 and the rear side is a steep slope 52.

  Thus, since the inflow port 40 bottom surface 26c has a plurality of inclination angles, the inflow speed of the game ball 23 about to flow into the passage hole 41a can be changed according to the position. For example, in the second embodiment, the game ball on the steep slope 52 on the back side (rear side) flows into the passage hole 41a at a higher speed than the game ball on the gentle slope 51 on the near side (front side). Can be made. That is, the speed of each game ball can be adjusted so that the game balls are separated from each other. Since a plurality of game balls smoothly flow into the passage hole 41a in the vicinity of the entrance of the passage hole 41a, it is possible to effectively prevent the biting of the balls and the resulting clogging of the balls.

  As shown in FIG. 11, in this out mouth portion 30, the inclination angle of the counting sensor 41, that is, the angle formed by the passing direction of the game ball 23 in the counting sensor 41 with the horizontal plane is larger than the steep slope 52 ( 20 °). That is, the game ball 23 flows into the out port while sequentially passing through the inclined surfaces of 5 °, 10 °, and 20 °.

  In the process in which the game balls 23 flow into the out port, the inclination angles become steeper in order from the front side (front side) to the back side (rear side), so that the game balls are separated from each other. Therefore, the effect of preventing one-ball chewing and ball clogging is increasing.

  Further, the angle (inclination angle) formed by the counting sensor 41 passing the game ball 23 with the horizontal plane is set to a relatively large angle of 20 °. Moreover, the inclination angle of the counting sensor 41 is set larger than the inclination angle of the gentle slope 51 and the steep slope 52. Therefore, erroneous detection due to so-called chattering in which the game ball 23 that has once passed through the counting sensor 41 flows backward for some reason and is detected again by the counting sensor 41 is effectively prevented.

  FIG. 12 is an exploded perspective view of the vicinity of the launch unit of the pachinko machine 2 according to the second embodiment. In FIG. 12, reference numeral 54 denotes a rectifier, reference numeral 55 denotes a launch unit, and reference numeral 56 denotes a foul ball collection port. In FIG. 12, only the main part is displayed, and the glass frame, game board, etc. in the pachinko machine 2 are omitted. Further, the rectifier 54 is shown disassembled forward.

  The rectifier 54 has a ball supply function of supplying game balls one by one toward the launch unit 55. The rectifier 54 includes a solenoid 54a and a ball feeding member 54b, and the ball feeding member 54b reciprocates by an on / off operation of the solenoid 54a. As the ball feeding member 54b reciprocates, the game balls are supplied to the launch unit 55 one by one from the supply passage 54c.

  In this rectifier 54, a ball passage sensor (launch ball number counter) 54d for detecting the passage of the game ball is disposed. Any position in the rectifier 54 may be used as long as it can detect the passage of the game ball. For example, it may be upstream or downstream of the ball feeding member 54b (that is, the supply passage 54c), or a ball passage sensor 54d may be attached to the ball feeding member 54b itself.

  When the ball passing sensor 54d detects the game balls supplied one by one, the number of game balls supplied to the launch unit 55, that is, the number of game balls launched toward the game area can be counted. .

  In addition, the game ball 23 supplied from the rectifier 54 is set in the launch rail 55c, and a launch ball 55 is fired toward the game area by the launch unit 55. The firing unit 55 has a function of launching the ball balls one by one in the launch rail 55c toward the game area by the launcher 55a. The ball operation of the launcher 55a is realized by the on / off operation of the solenoid 55b.

  A game ball that has been shot by the launch unit 55 but has not reached the game area, that is, a foul ball, falls into the foul ball collection port 56. The foul balls dropped into the foul ball collection port 56 are discharged to the ball tray 14 (particularly, the lower ball tray 14b) through the foul ball collection passage inside the pachinko machine 2. A sphere passage sensor 56a for detecting the passage of the foul sphere is disposed in the vicinity of the foul sphere collection port 56 or in the foul sphere collection passage. As a result, it is possible to count how many of the launched game balls have returned as foul balls.

  Based on the count value of the number of shot balls by the ball passage sensor 54d, the count value of the number of foul balls by the ball passage sensor 56a, the count value of the number of out balls by the count sensor 41, and the count value of the number of winning balls won in each winning opening. It is possible to detect and detect illegal acts such as thread hanging goto. That is, since the number of fired balls = the number of winning balls + the number of out balls + the number of foul balls should be established, even if a certain amount of counting error is taken into account, the number of fired balls and the number of winning balls + (the number of winning balls + the number of foul balls) When the difference from the total number) is equal to or greater than a predetermined number, it can be determined that an illegal act is being performed.

[Embodiment 3]
In the third embodiment, an example in which the outlet unit U is applied to a sealed circulation pachinko machine will be described. Like the pachinko machine 2 according to the first and second embodiments, the enclosed circulation pachinko machine has a rectifier, a launch unit, a game board, and a foul ball collection passage. A game area for realizing a game by the flow of a game ball is defined on the game board surface, and various winning holes are arranged in the game area. An out port unit U is attached to the game board, and a game ball that has not won any winning port flows into the out port portion 30 via the inflow port 40.

  Also in the enclosed circulation pachinko machine, the game balls are supplied to the launch unit one by one by the rectifier, and when the bullets are launched by the launch unit, the game balls flow down the game area. Among the game balls flowing down the game area, a certain one wins a winning opening, and a certain one flows into the out opening 30 without winning any of the winning openings. A game ball that has been fired but has a low firing strength and has not reached the game area flows into the foul ball collection port and reaches the foul ball collection passage.

  In a sealed circulation pachinko machine, a predetermined number of game balls are enclosed and circulated in the machine and do not have a ball tray. Accordingly, game balls are not replenished from the outside of the pachinko machine, and prize balls due to winning are not paid out to the outside of the pachinko machine. The enclosed circulation pachinko machine has a circulation path for game balls. The circulation path is a ball path that circulates again the game balls that have won the various winning holes, the game balls that have flowed into the out-port 30 and the game balls that have passed through the foul ball collection passage to the rectifier. The game ball returned to the rectifier by the circulation path is again supplied to the launch unit and fired.

  The enclosed circulation pachinko machine has, for example, a card insertion slot and a card information management unit. The card stores player credit information. Based on this credit information, a predetermined number of balls can be lent. For example, when a card on which credit information “100” is recorded is inserted into a card slot and a ball lending operation corresponding to credit information “25” is performed, the card credit information is set to 100−25 = Set to “75”. In addition, 25 balls corresponding to credit information “25” are lent.

  The ball lending is performed by setting the number of balls that can be launched (the number of remaining balls) of 25 balls in the enclosed circulation pachinko machine, rather than actually being supplied to the enclosed circulation pachinko machine. It is preferable that the remaining number of balls is displayed so as to be visible to the player at any location of the enclosed circulation pachinko machine.

  In the enclosed circulation pachinko machine, the game ball enclosed in the machine is used cyclically, so that the ball can be launched 25 times into the game area. Each time one ball is fired, the remaining number of balls is decremented by one. When the remaining number of balls becomes zero, it is impossible to fire the ball. Here, when the launched game ball becomes a foul ball, the number of remaining balls is not subtracted. Further, when a winning ball is acquired by winning, the acquired winning ball number is added to the remaining ball number.

  Also in this enclosed circulation pachinko machine, a ball passage sensor is arranged in the rectifier and the foul ball collection passage, a prize sensor is arranged in each prize opening, a counting sensor is arranged in the out mouth part, and the number of shot balls The number of foul balls, winning balls and out balls can be counted.

Number of remaining balls = number of balls lent + number of prize balls + number of foul balls-number of fired balls-(1)
Number of fired balls = number of winning balls + number of out balls + number of foul balls-(2)
It is determined whether or not the above relationship is established within a predetermined allowable count error range. In the above equation (1), the difference ball number (remaining ball number) is calculated. If the above equation (2) is not satisfied, it can be determined that an illegal act such as a hanging thread is being performed.

[Embodiment 4]
FIG. 13 is a perspective view of the vicinity of the rectifier 64 included in the pachinko machine 2 according to the fourth embodiment. The fourth embodiment is a modification example in which the rectifier 54 is modified into the rectifier 64 in the second embodiment described with reference to FIG. Therefore, in Embodiment 4, the same code | symbol is attached | subjected about the structure similar to Embodiment 2, and the description is abbreviate | omitted. FIG. 13A shows a state where the front cover 64a of the rectifier 64 is attached (normal state), and FIG. 13B shows a state where the front cover 64a is removed.

  As described in the second embodiment, the rectifier 64 has a ball supply function for supplying game balls one by one toward the launch unit 55. The upstream side standby passage 65 and the downstream side thereof are provided. It arrange | positions between the firing units 55 (refer FIG. 12). The rectifier 64 has a ball feed member 64b and a solenoid 54a. The standby passage 65 and the rectifier 64 are disposed on the glass frame 12 side, and the launch unit 55 is disposed on the front frame 9 side. The rectifier 64 may be disposed on the front frame 9 side together with the firing unit 55.

  The standby passage 65 is connected to the upper ball tray 14 a on the upstream side, and is inclined downward toward the inlet 64 e of the rectifier 64. The game balls 23 stored in the upper ball tray 14a are aligned in a line in the standby passage 65, and reach the rectifier 64 from the inlet 64e. Then, the ball feeding member 64b reciprocally swings around the shaft 64f in the ± α direction in the drawing, so that the game balls 23 from the inlet 64e are supplied to the launch unit 55 one by one through the outlet 64g. It has come to be.

  In the vicinity of the ball feeding member 64b, a firing ball number counter 64d is arranged. The firing ball number counter 64d has a detection piece 67 and a light projecting / receiving sensor 68 that can swing back and forth in the ± α direction around a shaft 66. The detection piece 67 includes a contact piece 67a that comes into contact with the game ball 23 on the ball feeding member 64b and a light shielding piece 67b that can shield the sensor light of the light projecting / receiving sensor 68 at the detection position.

  When the game ball 23 is not on the ball feeding member 64b, the contact piece 67a does not contact the game ball 23, the detection piece 67 rotates in the -α direction (counterclockwise in the figure), and the light shielding piece 67b The sensor light deviates from the detection position, and as a result, the sensor light is not shielded (translucent state). However, when the game ball 23 is on the ball feeding member 64b, the contact piece 67a contacts the game ball 23, the detection piece 67 rotates in the + α direction (clockwise in the figure), and the light shielding piece 67b is the sensor. The light enters the detection position by light, and as a result, the sensor light is shielded (shielded state).

  As the ball feeding member 64b reciprocally swings, the game balls 23 are supplied to the launch unit 55 one by one, and the game ball 23 on the ball feed member 64b is present and absent each time the ball is supplied. Then, every time one game ball 23 is supplied, the light projecting / receiving sensor 68 repeats the light transmitting / shading state, and the passage of each game ball 23 is detected. The number of detected balls passing by the light projecting / receiving sensor 68 corresponds to the number of balls fired by the launching unit 55, so that the number of shots of the game ball 23 is counted by the light projecting / receiving sensor 68 and the detection piece 67. It functions as a ball counter 64d.

  Also in the pachinko machine 2 according to the fourth embodiment, as in the first and second embodiments, the out mouth portion 30 includes the counting sensor 41 (see FIG. 5), and the game ball 23 enters the out mouth portion 30. It is comprised so that the number of can be counted. Therefore, the pachinko machine 2 according to the fourth embodiment can realize the counting of the number of shot balls by the number of shot balls counter 64d and the counting of the number of out balls by the counting sensor 41. In any pachinko machine according to any of the embodiments, the number of winning balls won in each winning opening (normal winning opening 28, starting winning opening 29, large winning opening 31), etc. is counted.

  Unless the number of foul balls is taken into account, the number of shot balls = the number of winning balls + the number of out balls is substantially established. However, when an illegal act such as a thread hanging goto is performed, the apparent number of winning balls is increased, and the sum of the number of winning balls + the number of winning balls is larger than the number of shot balls. Therefore, the pachinko machine 2 obtains the count value of the number of shot balls by the shot ball counter 64d, the count value of the number of out balls by the count sensor 41, and the count value of the number of winning balls by the winning sensor at each winning opening. It is possible to determine whether or not an illegal act such as a thread hanging goto is being performed.

  In the vicinity of the outlet 64e in the front cover 64a, as shown in FIG. The illegal act disabling means 70 has a clip 70a and a cutter 70b in the fourth embodiment.

  The clip 70a forms a sandwiching portion 70c with two parallel and narrow metal wires. The clip 70a holds the thread connected to the game ball for the thread hanging goto between the gripping portions 70c when the game ball illegally processed for the thread hanging goto is launched from the rectifier 64 to the launch unit 55. It is supposed to be.

  One end of the thread hanging thread is connected to an illegally processed game ball, and the other end is gripped by an unauthorized person through the rectifier 64, the standby passage 65, and the upper ball tray 14a. Since the thread hanging thread held in the holding section 70c is fixed or at least semi-fixed, the fraudster cannot operate the thread smoothly and illegally removes and inserts the game ball. Can not be. Thereby, it is possible to prevent or at least make an illegal act by the thread hanging goto.

  The cutter 70b is arranged so that the blade is positioned in the middle of the sandwiching portion 70c in the depth direction. When the yarn for thread hanging goto is pinched deeply by a certain degree or more, it is cut by the cutter 70b. When the cheating person launches the game ball for the thread hanging goto, the thread is pinched by the pinching portion 70c. Thereafter, when the cheating person pulls the thread by trying to perform the cheating, the thread is deeply clamped by the clamping part 70c, and as a result, is cut by the cutter 70b.

  Note that the detection piece 67 itself may constitute the fraud invalidation means 70. For example, as shown in FIG. 14, a blade portion 67 c for cutting a yarn for hanging yarn may be formed on a part of the detection piece 67. Further, a clamping part (not shown) for clamping a thread hanging thread may be formed in a part of the detection piece 67.

  In the pachinko machine 2 according to the fourth embodiment, the number of foul balls can also be counted if the ball passing sensor 56a serving as a foul ball counter for counting the number of foul balls is arranged. Thereby, based on the relationship of the number of shot balls = the number of winning balls + the number of out balls + the number of foul balls, it is possible to determine that an illegal act such as a thread hanging goto has been performed in consideration of the number of foul balls.

  Further, the fired ball number counter 64d is only required to be able to count the number of game balls that have been fired or the number that can be equated with it, and is not necessarily disposed in the vicinity of the rectifier 64. For example, as shown by a broken line in FIG. 13, if a ball passing sensor 65 is disposed in the standby passage 65, the number of passing balls in the standby passage 65 that can be regarded as the number of shot balls can be counted. .

  Further, for example, as shown in FIG. 12, a ball passage sensor 55d may be disposed on a part of the firing rail 55c. The number of game balls fired from the launch rail 55c and passed through the ball passage sensor 55d can be counted to obtain the number of fired balls.

  As shown in FIG. 15, the tip portion of the inner rail 24 mounted on the game board 6, that is, the launched game ball enters the game area 16 from the rail passage sandwiched between the inner rail 24 and the outer rail 26a. A return preventing member 72 for preventing the game ball from returning to the rail passage is attached to the portion. In the vicinity of the return prevention member 72, an operation sensor 73 for detecting the operation of the return prevention member 72 may be arranged as a shot ball number counter.

  The launched game ball hits the return prevention member 72 and enters the game area 16. The bounced return preventing member 72 is restored to its original position after the game ball passes due to its elasticity. That is, the return preventing member 72 performs the elastic deformation-restoration operation once for each game ball fired. By detecting the elastic deformation / restoring operation once by the motion sensor 73, a count value that can be equated with the number of shot balls can be obtained. The motion sensor 73 may be a micro switch that is physically pressed by the return prevention member 72, an optical sensor installed so that the detection light is shielded by the operation of the return prevention member 72, or the return prevention. It may be a magnetic sensor or an electrostatic sensor that detects the operation of the member 72 magnetically or electrostatically.

  Of course, a ball passage sensor that detects the passage of the game ball may be arranged at any position in the rail passage that does not affect the passage of the game ball. Also, in the pachinko machine 2 according to the fourth embodiment, the out port unit U is configured to include the out port portion 30 and the rail decoration portion 26 as in the second embodiment, but in the fourth embodiment, The out port 30 does not necessarily have a plurality of counting sensors 41. Even if the out mouth portion 30 has one counting sensor 41 and is configured so that all the out balls can be counted by the one counting sensor 41, the pachinko machine 2 according to the fourth embodiment is used. The function of is fully demonstrated.

[Example 1]
In the pachinko machine 2 according to the first embodiment described above, a confirmation experiment was performed as to how many ball distributions are counted by the right counting sensor 41 and the left counting sensor 41.

  In addition, at that time, the presence or absence of the occurrence of clogging in the vicinity of the out mouth portion 30 and the presence or absence of erroneous detection due to chattering in the counting sensor 41 were also confirmed. The experimental results are shown in Table 1.

以上の実験結果から明らかなように、流入口４０を左右非対称にし、誘導面４３の曲率半径を計数センサ４１ごとに異なる曲率半径とすることにより、左側の計数センサ４１に流入するアウト球の個数と右側の計数センサ４１に流入するアウト球の個数との比率をアンバランス（約４７％：約５３％）とすることができた。その際、アウト球の総個数が約４万発〜約１０万発程度となるまで球発射を行っても、アウト口部３０近傍における球詰まり、計数センサ４１におけるチャタリングによる誤検出の発生はなかった。

As is clear from the above experimental results, the number of out spheres flowing into the left counting sensor 41 is made by making the inlet 40 asymmetrical and the curvature radius of the guide surface 43 being different for each counting sensor 41. And the number of out-spheres flowing into the right counting sensor 41 could be unbalanced (about 47%: about 53%). At that time, even if the ball is fired until the total number of out balls reaches about 40,000 to about 100,000, there is no occurrence of erroneous detection due to clogging in the vicinity of the out mouth 30 and chattering in the counting sensor 41. It was.

  In this experiment, the winning of the launched game ball into the winning opening is not considered. That is, the experiment was performed in a situation where all of the launched game balls flow into the out port 30. Therefore, any experiment No. The total number of shots = total number of out balls.

[Example 2]
In the pachinko machine 2 according to the second embodiment described above, a confirmation experiment was performed as to how many ball distributions are counted by the right counting sensor 41 and the left counting sensor 41.

  In addition, at that time, the presence or absence of the occurrence of clogging in the vicinity of the out mouth portion 30 and the presence or absence of erroneous detection due to chattering in the counting sensor 41 were also confirmed. The experimental results are shown in Table 2.

以上の実験結果から明らかなように、流入口４０を左右非対称にし、誘導面４３の曲率半径を計数センサ４１ごとに異なる曲率半径とすることにより、左側の計数センサ４１に流入するアウト球の個数と右側の計数センサ４１に流入するアウト球の個数との比率をアンバランス（約４７％：約５３％）とすることができた。それに加え、底面２６ｃに傾斜角度の異なる緩斜面５１と急斜面５２とを形成することにより、アウト球の総個数が約４万発〜約１０万発程度となるまで球発射を行っても、アウト口部３０近傍における球詰まり、計数センサ４１におけるチャタリングによる誤検出の発生はなかった。

As is clear from the above experimental results, the number of out spheres flowing into the left counting sensor 41 is made by making the inlet 40 asymmetrical and the curvature radius of the guide surface 43 being different for each counting sensor 41. And the number of out-spheres flowing into the right counting sensor 41 could be unbalanced (about 47%: about 53%). In addition, by forming the gentle slope 51 and the steep slope 52 with different inclination angles on the bottom surface 26c, even if the ball is fired until the total number of out balls reaches about 40,000 to about 100,000, There was no occurrence of erroneous detection due to clogging in the vicinity of the mouth 30 or chattering in the counting sensor 41.

  Also in this experiment, the winning of the game ball that was launched into the winning opening is not considered. That is, the experiment was performed in a situation where all of the launched game balls flow into the out port 30. Therefore, any experiment No. The total number of shots = total number of out balls.

[Example 3]
In the pachinko machine 2 used in the second embodiment, it is confirmed whether or not the ball clogging occurs in the vicinity of the out mouth 30 when the total number of shots is 1 million or more, and whether or not there is a false detection due to chattering in the counting sensor 41 did. The experimental results are shown in Table 3.

実施形態２に係るアウト口ユニットを使用することにより、約１４５万発の球発射を行っても、アウト口部３０近傍における球詰まり、計数センサ４１におけるチャタリングによる誤検出の発生がないことがわかった。

By using the out port unit according to the second embodiment, it is understood that there is no occurrence of clogging in the vicinity of the out port 30 and erroneous detection due to chattering in the counting sensor 41 even when about 1.45 million balls are fired. It was.

  Also in this experiment, the winning of the game ball that was launched into the winning opening is not considered. That is, the experiment was performed in a situation where all of the launched game balls flow into the out port 30. Therefore, any experiment No. The total number of shots = total number of out balls.
