Abstract

<P>PROBLEM TO BE SOLVED: To provide a pinball game machine which can distinctively detect balls shot into a winning opening for every mode of the opening. <P>SOLUTION: Right and left blades 3 and 4 have projecting walls 3a and 4a projecting to the facing sides and increasing the projection amounts downward. The right and left blades 3 and 4 are separated larger than the diameter W10 of a shot ball 20 in the upper side W1 and smaller than the diameter W10 of the shot ball 20 in the lower side W2 by the projecting walls 3a and 4a during shrinkage. Since both projecting walls 3a project smaller toward a game board 10 side, a shot ball 20 winning during shrinkage is stopped from dropping in a nearly half position of the projecting walls 3a and 4a and delivered to a first winning route 11 on the rear side of the game board 10 along the slopes of the projecting walls 3a and 4a. On the other hand, during expansion of the winning opening 1, the shot ball 20 drops without being blocked by the projecting walls 3a and 4a and delivered to a second winning route 12. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a ball game machine typified by a pachinko gaming machine that plays a game by hitting a ball into a game area, and particularly detects a ball that has won a single winning opening separately for each aspect of the winning opening. The present invention relates to a ball game machine that can be used.

  In general, pachinko machines are provided with various standards, and can only be shipped if they pass this standard. Therefore, various tests are performed before shipment of the pachinko gaming machine, and it is checked whether or not the test results are within the standard. In such a test, for example, the ratio of prize balls due to an accessory (an accessory ratio) and the average number of winning balls of an ordinary electric accessory in a high probability state are examined. In the first type pachinko machine P of FIG. 10, since there are two prizes of the prize winning port 61 and the big prize winning hole 62 related to the ordinary electric bonus, the prize ratio is as shown in the equation (1), In addition, the average number of winning balls of the ordinary electric accessory in the high probability state is obtained as shown in Expression (2).

上記式（１）および（２）からわかるように、役物比率などを求める場合には、普通電動役物に係る入賞口６１の拡大時における入賞球数を検出する必要がある。このため該試験時には、入賞口６１の上方に配設される遊技くぎ６３，６４の間にスイッチを取り付け、かかる遊技くぎ６３，６４を通過した打球の数を入賞口６１の縮小時における入賞球数と判断し、入賞口６１の全入賞球数と遊技くぎ６３，６４間を通過した打球の数との差により、入賞口６１の拡大時における入賞球数を検出していた。

As can be seen from the above formulas (1) and (2), when determining the ratio of the winning combination etc., it is necessary to detect the number of winning balls when the winning slot 61 relating to the ordinary electric accessory is enlarged. For this reason, at the time of the test, a switch is attached between the game nails 63 and 64 disposed above the winning hole 61, and the number of hit balls passing through the game nails 63 and 64 is determined as the winning ball when the winning hole 61 is reduced. The number of winning balls when the winning opening 61 was enlarged was detected based on the difference between the total number of winning balls in the winning opening 61 and the number of hit balls that passed between the game nails 63 and 64.

  However, there are cases where the hit ball that passes between the game nails 63 and 64 does not win the winning hole 61 or when the win hole 61 is enlarged, the hit ball wins between the game nails 63 and 64. In any case, the number of winning balls is erroneously counted, and there is a problem that an accurate test result cannot be obtained.

  The present invention has been made in order to solve the above-described problems, and provides a ball game machine capable of distinguishing and detecting a hit ball won in one winning opening for each aspect of the winning opening. It is aimed.

In order to achieve this object, the ball game machine according to claim 1 is a ball ball game machine in which a game is performed by hitting a hit ball into the game area, and a prize that can be changed in two or more modes provided in the game area. Passing through the mouth, two or more winning paths through which a hit ball that has won the winning opening passes, a switching device that switches the winning paths according to the mode of the winning mouth, and the winning path switched by the switching device And a detecting device for detecting a hit ball.
According to the bullet ball gaming machine of the first aspect, the hit ball that is driven into the game area is sent to the winning ball discharging unit through the winning path after winning the winning opening. The winning path through which the hit ball passes is switched by the switching device according to the mode of the winning opening, and the hit ball that has passed through the winning path is detected by the detecting device. Therefore, the hit ball that has won a prize is distinguished and detected for each aspect of the prize opening.

  According to the bullet ball game machine of the first aspect, a winning path through which a hit ball that has won a prize opening passes is switched according to a mode of the winning opening. Therefore, there is an effect that the hit ball that has won a prize can be detected for each aspect of the winning opening. For this reason, for example, an accurate test result can be obtained in a test performed before shipment.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. This embodiment will be described using a pachinko gaming machine as an example of a ball game machine. Fig.1 (a) is a front view of the winning opening which concerns on the ordinary electric accessory of the pachinko machine in a present Example, FIG.1 (b) is the sectional side view. FIGS. 1A and 1B show a mode when the winning opening is reduced. FIG. 2 (a) is a front view when the winning opening is enlarged, and FIG. 2 (b) is a side sectional view thereof.

  This winning opening 1 is a winning opening relating to an ordinary electric accessory, and has two modes: when the left and right blades 3 and 4 are closed (FIG. 1) and when they are opened (FIG. 2). I have. The winning opening 1 is activated when a game ball wins a specific winning opening, passes a specific gate, or a specific symbol combination is displayed.

  As shown in FIGS. 1A and 1B, the winning opening 1 includes a base plate 5 attached to the game board surface 10, and the front cover 2 is attached to the base plate 5. ing. Non-penetrating shaft holes 2a and 2b are provided on the rear surfaces of the upper side portions of the front cover 2, and the shaft pins 3b (4b) of the left blade 3 and the right blade 4 forming tulip petals in both shaft holes 2a and 2b. ) Is attached to each axis.

  Both the left wing 3 and the right wing 4 are provided with projecting walls 3a and 4a projecting to the opposite surface side, and both projecting walls 3a and 4a are inclined walls whose projecting amounts are increased toward the lower side. Has been. The distance between the left and right blades 3 and 4 by the protruding walls 3a and 4a is such that when the left and right blades 3 and 4 are closed, the upper side W1 is larger than the diameter W10 of the hit ball 20 and the lower side W2 is the diameter of the hit ball 20. It is formed smaller than W10 (W1> W10> W2). Further, as shown in FIG. 1B, both the projecting walls 3a (4a) are inclined walls whose projecting amounts become smaller toward the game board surface 10 side. Therefore, the hit ball 20 that has won the winning opening 1 at the time of reduction is stopped from dropping at a position substantially half of both the protruding walls 3a and 4a, and then the game board surface along the inclination of both the protruding walls 3a and 4a. 10 is sent to the first winning path 11 formed on the back side.

  As shown in FIG. 1B, the interval W4 between the left and right blades 3 and 4 and a connecting piece 7d of the solenoid arm 7 described later is formed smaller than the diameter W10 of the hit ball 20 (W4 <W10). ), The hit ball 20 does not fall down on the way from the projecting walls 3a, 4a to the connecting piece 7d and enter the second winning path 12.

  Pushing portions 3c (4c) are formed at the lower ends of the left blade 3 and the right blade 4. When the pushing portion 3c (4c) is pushed upward by the distal end portion 7a of the solenoid arm 7, as shown in FIGS. 2 (a) and 2 (b), the winning opening 1 has left and right blades 3 and 4 opened. It changes to an enlarged state.

  The solenoid arm 7 is a member that expands and contracts the left and right blades 3 and 4 and constitutes a part of each of the winning paths 11 and 12. FIG. 3 is a perspective view of the solenoid arm 7. The solenoid arm 7 includes a pair of swinging pieces 7c and 7c formed in the same shape, and the pair of swinging pieces 7c and 7c has a rod-like connecting member 7e at the rear end and a plate-like connecting piece. The central portions are connected by 7d.

  The connecting piece 7d is formed in a substantially L shape that has a front portion bent upward and a rear portion extending along the lower end of the swing piece 7c. As shown in FIG. 1B, the rear portion of the connecting piece 7d that extends along the lower end of the swing piece 7c is coupled with the path wall 11c, and part of the first winning path 11 is reduced when the winning opening 1 is reduced. Form. On the other hand, the front portion of the connecting piece 7d bent upward has an interval W6 between its tip and the upper wall of the first winning path 11 when the winning opening 1 is enlarged as shown in FIG. It is formed to be smaller than the diameter W10 of the hit ball 20 (W6 <W10). Therefore, the connecting piece 7 d functions as a closing wall of the first winning path 11 so that the hit ball 20 does not enter the first winning path 11 but enters the second winning path 12 when the winning opening 1 is enlarged.

  As shown in FIG. 2B, the interval W7 between the rear end of the connecting piece 7d when the winning opening 1 is enlarged and the path wall 11c that partitions the first winning path 11 and the second winning path 12 is a hit ball. It is formed smaller than the diameter W10 of 20 (W7 <W10). Therefore, when the winning hole 1 is reduced, the ball 20 is on the connecting piece 7d (FIG. 1 (b)), and the solenoid arm 7 is swung to enlarge the winning hole 1, and FIG. 2 (b). Even if it comes to show, the hit ball 20 once entering the first winning path 11 never enters the second winning path 12 from the gap W7.

  In FIG. 3, shaft pins 7b projecting outward are respectively provided slightly above and behind the center of each swing piece 7c. The solenoid arm 7 is pivotally attached to both side walls of the first winning path 11 with the shaft pin 7b as a swing shaft. An engagement recess 7f is formed at the rear end of the solenoid arm 7, and a protrusion (not shown) of the drive plate 8 attached to the solenoid 9 is engaged with the engagement recess 7f. Therefore, the solenoid arm 7 is swung around the shaft pin 7 b in conjunction with the operation of the solenoid 9. Further, a pair of tip portions 7 a formed in a rod shape are provided at the tip of the solenoid arm 7. The tip 7a swings up and down along an arcuate locus by swinging of the solenoid arm 7, and enlarges or reduces the left and right blades 3 and 4 of the winning opening 1. It should be noted that only one engagement recess 7f is provided in the solenoid arm 7.

  As shown in FIG. 1 (b), two winning paths 11 and 12 through which the hit ball 20 that has won the winning hole 1 pass are formed on the back surface of the game board surface 10. The first winning path 11 through which the hit ball 20 won when the left and right blades 3 and 4 are closed passes is arranged above, and the hit ball that won when the left and right blades 3 and 4 are opened is arranged below. A second winning path 12 through which 20 passes is arranged.

  A pair of shaft holes are formed in the side wall of the first winning path 11 (not shown), and the left and right shaft pins 7b of the solenoid arm 7 are pivotally attached to the shaft holes. Further, a notch 11 a is provided above the first winning path 11 so that the solenoid arm 7 and the drive plate 8 of the solenoid 9 can be connected. Since the width W3 of the notch 11a is smaller than the diameter W10 of the hit ball 20 (W3 <W10), the hit ball 20 entering the first winning path 11 does not jump out of the notch 11a. Ring sensors 11b and 12b are provided in the middle of the winning paths 11 and 12, so that the number of hit balls 20 that have passed through the winning paths 11 and 12 can be detected.

  On one side outside the winning paths 11 and 12, the solenoid arm 7 is swung to open and close the left and right blades 3 and 4, and the solenoid 9 that enlarges or reduces the winning opening 1 is driven up and down by the solenoid 9. Drive plate 8 is provided. As shown in FIG. 1B, when the solenoid 9 is operated and the drive plate 8 is moved upward, the solenoid arm 7 is pivoted downward about the shaft pin 7b, and the winning opening 1 is reduced. Change to state. On the other hand, as shown in FIG. 2B, when the solenoid 9 is operated and the drive plate 8 is moved downward, the solenoid arm 7 is swung upward about the shaft pin 7b, and the left and right blades 3 and 4 push-up portions 3c (4c) are pushed up to change the winning opening 1 to the enlarged state. As shown in FIG. 2A, the minimum interval W5 between the left and right blades 3 and 4 in this expanded state is formed larger than the diameter W10 of the hit ball 20 (W5> W10). Therefore, the hit ball 20 that won the winning opening 1 at the time of expansion falls to the lowermost end of the winning opening 1 without being blocked by the protruding walls 3a, 4a of the left and right blades 3, 4, and the second on the back side of the game board surface 10 It is sent to the winning path 12.

  FIG. 4 is a block diagram showing an electrical configuration of the pachinko gaming machine. The control unit 40 of the pachinko gaming machine includes a CPU 41 that is an arithmetic device, a ROM 42 that stores each control program executed by the CPU 41, and a RAM 43 that is a memory for storing various data. Note that the program of the flowchart shown in FIG. 5 is stored in the ROM 42.

  The CPU 41, ROM 42, and RAM 43 are connected to each other via a bus line 44. The bus line 44 is also connected to an input / output port 45. The input / output port 45 includes a sensor 11b provided in the first winning path 11, a sensor 12b provided in the second winning path 12, and a winning opening 1. Is connected to other input / output devices 46 including a display device.

  Further, a connector 47 is connected to the input / output port 45. At the time of the pre-shipment test of the pachinko gaming machine, an inspection device is connected to the connector 47 and various tests are performed. In this test, the detection results of the sensors 11b, 12b, etc. are tabulated by the inspection device, and the number of winning balls at the time of expansion and contraction of the winning opening (ordinary electric accessory) 1 is individually grasped. .

  Next, the operation when the hit ball 20 wins the winning opening 1 configured as described above will be described. As shown in FIGS. 1 (a) and 1 (b), when the hit ball 20 wins when the left and right blades 3 and 4 of the winning opening 1 are closed, the hit ball 20 is at the substantially central portion of the protruding walls 3a and 4a. The fall is stopped, and after that, it is carried to the back side of the game board surface 10 along the inclination of the protruding walls 3a, 4a. Two winning paths, a first winning path 11 and a second winning path 12, are formed on the back side of the game board surface 10. When the winning opening 1 is reduced, the hitting ball 20 is moved by the connecting piece 7d of the solenoid arm 7. It is carried to the first winning path 11 disposed above. The hit ball 20 carried to the first winning path 11 moves from the connecting piece 7d of the solenoid arm 7 to the path wall 11c, eventually passes through the sensor 11b, moves to the winning ball discharge unit (not shown), and is discharged. Is done. As described above, the sensor 11b detects the passing of the hit ball 20, so that it is possible to detect the hit ball 20 won when the winning opening 1 is reduced. As described above, the intervals W3 and W4 are formed smaller than the diameter W10 of the hit ball 20 (W3 <W10, W4 <W10), so that the hit ball 20 moving on the first winning path 11 is the second winning path. 12 or from the first winning path 11 through the notch 11a can be prevented.

  On the other hand, as shown in FIGS. 2A and 2B, when the hit ball 20 wins when the left and right blades 3 and 4 of the winning opening 1 are expanded, the hit ball 20 passes between the protruding walls 3a and 4a. Then, it falls to the lowermost end of the front cover 2 and is carried to the second winning path 12. The hit ball 20 carried to the second winning path 12 passes through the sensor 12b, moves to a winning ball discharge unit (not shown), and is discharged. Thus, the sensor 12 b detects the passing of the hit ball 20, whereby the hit ball 20 won when the winning opening 1 is enlarged can be detected. As described above, since the intervals W6 and W7 are formed smaller than the diameter W10 of the hit ball 20 (W6 <W10, W7 <W10), the hit ball 20 moves from the gap W6 to the first winning path when the winning opening 1 is enlarged. 11 or entering the first winning path 11 through the gap W7 during the movement of the second winning path 12 can be prevented.

  Next, the operation of the pachinko gaming machine configured as described above will be described based on the flowchart of FIG. Such processing is executed by the control unit 40 of the pachinko gaming machine described above.

  First, it is checked whether or not the hit ball 20 has won when the winning opening 1 is reduced, that is, whether or not the sensor 11b has detected the hit ball 20 (S1). When the sensor 11b detects the hit ball 20 (S1: Yes), for example, five game balls are paid out (S2), and then the process A is executed (S3). The process A is a process executed when the hit ball 20 wins when the winning opening 1 is reduced. For example, the process A is performed by the normal symbol display device 65 (see FIG. 10) configured by eight segment LEDs provided in the pachinko gaming machine. This is a process for starting fluctuation.

  When the sensor 11b does not detect the hit ball 20 (S1: No), it is checked whether or not the sensor 12b has detected (S4). If the sensor 12b detects the hit ball 20 (S4: Yes), it means that the hit ball 20 has won when the winning opening 1 is enlarged. In this case, for example, 10 game balls are paid out (S5). . After the game balls are paid out, process B is executed (S6). The process B is a process executed when the hit ball 20 wins when the winning slot 1 is enlarged. For example, the process B changes the special symbol display device 66 (see FIG. 10) configured by a liquid crystal display provided in the pachinko gaming machine. It is a process to start.

  If none of the sensors 11b and 12b detect the hit ball 20 (S4: No), there is no hit ball 20 that has won the winning opening 1 and other processing is executed according to the situation (S7). After execution of the process A (S3), the process B (S6), and the other process (S7), each process is shifted to S1, and the above-described process is continued.

  As described above, according to the ball game machine of the present embodiment, the winning path can be made different between when the winning opening 1 is reduced and when the winning opening 1 is enlarged. 20 can be detected accurately. Further, when the hit ball 20 wins the winning opening 1, the number of winning balls to be paid out and the processing executed thereafter can be changed according to the form of the winning opening 1. That is, one winning opening 1 can be handled as if it were two or more winning openings according to the mode. Thereby, the interest of the game is further improved.

  Next, a second embodiment will be described with reference to FIGS. The pachinko gaming machine according to the second embodiment is configured to accurately detect the number of winning balls when the winning opening 1 is enlarged and the number of winning balls when the winning opening 1 is reduced only in a test before shipment. In the following, the same parts as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only the parts unique to the second embodiment will be described.

  As shown in FIGS. 6 and 7, in the pachinko gaming machine of the second embodiment, the third winning path 50 where the two winning paths 11, 12 merge downstream of the first winning path 11 and the second winning path 12. I have. A ring-shaped sensor 51 is attached to the third winning path 50 so that the number of hit balls 20 passing through the third winning path 50 can be detected. The end of the third winning path 50 is connected to a winning ball discharge unit (not shown), and the hit ball 20 sent from the first or second winning path 11, 12 to the third winning path 50 is further It is sent to the winning ball discharging unit and discharged from the winning ball discharging unit.

  A ring-shaped sensor 52 is detachably attached to the first winning path 11. This sensor 52 is a sensor that detects the number of winning balls when the winning opening 1 is reduced in the pre-shipment test of the pachinko gaming machine, and is attached during the pre-shipment test and removed after the test. That is, the test is performed with the two sensors 51 and 52 attached before the product is shipped, but after the test is finished, the sensor 52 of the first winning path 11 is removed and shipped. is there.

  FIG. 8 is a block diagram showing an electrical configuration during a pre-shipment test of the pachinko gaming machine. In the pre-shipment test of the pachinko gaming machine, a test control circuit board on which the control unit 53 is mounted is attached instead of the control circuit board for shipment. After completion of the pre-shipment test, the test control circuit board on which the control unit 53 is mounted together with the sensor 52 of the first winning path 11 is removed, and then the shipping control circuit board is attached and shipped. .

  The control unit 53 that performs a pre-shipment test includes a CPU 54 that is an arithmetic device, a ROM 55 that stores various test programs executed by the CPU 54 including the program of the flowchart shown in FIG. 9, and an enlargement counter 56a and a reduction counter 56b. And a RAM 56 having a work memory.

  The expansion counter 56a is a counter that counts the number of winning balls when the winning opening 1 is expanded in the pre-shipment test. “0” is cleared at the start of the test, and 1 is added each time the sensor 51 of the third winning path 50 detects the hit ball 20. When the sensor 52 of the first winning path 11 detects the hit ball 20, the value of the enlargement counter 56a is decremented by 1 for each detection. This is because, if the hit ball 20 wins when the winning opening 1 is reduced, the one hit ball 20 is detected by both sensors 51 and 52.

  The reduction counter 56b is a counter that counts the number of winning balls when the winning opening 1 is reduced in the pre-shipment test. As with the enlargement counter 56a, “0” is cleared at the start of the test. After the start of the test, 1 is added each time the sensor 52 attached to the first winning path 11 detects the hit ball 20.

  The CPU 54, ROM 55, and RAM 56 are connected to each other via a bus line 57. The bus line 57 is also connected to an input / output port 58. The input / output port 58 includes a sensor 51 provided in the third winning path 50, a sensor 52 provided in the first winning path 11, and the winning opening 1. Is connected to other input / output devices 46 including a display device.

  Next, the operation during the pre-shipment test of the pachinko gaming machine configured as described above will be described based on the flowchart of FIG. Such processing is executed by the control unit 53 described above.

  In this process, first, the values of the enlargement counter 56a and the reduction counter 56b are cleared to “0” (S11). Next, it is checked whether or not the sensor 51 of the third winning path 50 detects the hit ball 20 (S12). If the sensor 51 detects the hit ball 20 (S12: Yes), the enlargement counter 56a is once set. Is incremented by “1” (S13). If the sensor 51 only detects the hit ball 20, it is unknown whether the winning slot 1 is awarded when the winning slot 1 is enlarged or the prize is awarded when the winning slot 1 is reduced. In this case, the value of the enlarging counter 56 a is temporarily set to “ 1 ”is added (S13), and when the sensor 52 of the first winning path 11 detects the hit ball 20, the value of the added enlargement counter 56a is subtracted by“ 1 ”.

  When the sensor 51 does not detect the hit ball 20 (S12: No), or after the process of S13, the process proceeds to S14 to check whether the sensor 52 of the first winning path 11 has detected the hit ball 20 or not. (S14). When the sensor 52 detects the hit ball 20 (S14: Yes), it is a win when the winning opening 1 is reduced, so that the value of the reduction counter 56b is incremented by "1" (S15) and the enlargement counter 56a "1" is subtracted from the value of (S16). This is because, as described above, the hit ball 20 won when the winning opening 1 is reduced is detected by both the sensors 51 and 52. If the sensor 52 does not detect the hit ball 20 (S14: No) or after the process of S16, the process proceeds to S12 and the above-described processes of S12 to S17 are repeatedly executed.

  As described above, in the ball game machine of the second embodiment, the number of winning balls when the winning opening 1 is enlarged is displayed on the expansion counter 56a, and the number of winning balls when the winning opening 1 is reduced is displayed on the reducing counter 56b. Is remembered. Therefore, based on the values of both the counters 56a and 56b, it is possible to accurately calculate the winning combination ratio and the average number of winning balls of the electric winning combination.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, in the present embodiment, the winning paths 11 and 12 of the winning ball (winning ball) 20 are changed according to the “change in form” of enlargement or reduction of the winning opening 1. However, the winning path of the winning ball may be changed not only according to “change in form” but also according to “change in gaming state (gaming mode)”. The “game mode change” includes a high probability state and a low probability state, and the normal symbol display device 65 and the special symbol display device 66 being operated and stopped. Note that it is naturally possible to apply the present invention to a prize opening other than the ordinary electric accessory or to a ball game machine other than a pachinko game machine.

  Furthermore, the present invention can be developed as follows. In a ball game machine that plays a game by driving a hit ball into a game area, a winning opening that is provided in the gaming area and can be changed into two or more modes, and two or more winning paths through which a hit ball that has won the winning opening passes A switching device that switches the winning path according to the mode of the winning opening, a detection device that detects a hit ball that passes through the winning path switched by the switching device, and 2 when the hit ball has won the winning opening. A bullet ball game comprising payout means capable of paying out more than one kind of game balls, and control means for switching the number of game balls paid out by the payout means according to the form of the winning opening based on the detection result by the detection device Machine. The payout means in this case corresponds to the processes of S2 and S5 in FIG. 5, and the control means corresponds to the processes of S1 and S4 in FIG.

  In addition, in a ball game machine that plays a game by hitting a ball into the game area, the game area is provided with a winning opening that can be changed into two or more modes, and two or more winning prizes through which the hit ball that has won the winning hole passes A path, a switching device that switches the winning path according to the mode of the winning opening, a detection device that detects a hit ball that passes through the winning path switched by the switching device, and a hit ball that wins the winning opening The game state display means that can display two or more types of game states and the game state displayed by the game state display means are switched in accordance with the form of the winning opening based on the detection result of the detection device. And a ball game machine comprising a control means. In this case, the game state appearance means corresponds to the processes of S3 and S6 in FIG. 5, and the control means corresponds to the processes of S1 and S4 in FIG.

  In a ball game machine that plays a game by driving a hit ball into the game area, a winning opening that can be changed into two modes provided in the gaming area, two winning paths through which the hit ball that has won the winning opening passes, A switching device that switches a winning path through which a hit ball passes according to the winning opening, a merging path where the two winning paths merge, a merging path provided in the merging path, and passing through the merging path A ball game machine comprising a first detection device that detects a hit ball and a second detection device that is provided on one of the winning paths and detects a hit ball that passes through the one winning path. According to this ball game machine, the number of hit balls passing through one winning path is detected by the second detecting device, and the number of hit balls passing through the other winning path is the number of hit balls detected by the first detecting device. Is calculated by subtracting the number of hit balls detected by the second detector. Therefore, according to this bullet ball game machine, it is possible to accurately detect the number of hit balls won for each mode of the winning opening.
