Description

  The present invention relates to a ball game machine.

  Conventionally, in a ball game machine (also referred to as a pachinko game machine, a pachinko machine, or simply a game machine), when a game ball that has been launched enters a winning opening, a prize ball is paid out. By exploiting this, an illegal act using a game ball with a thread (referred to as a ball with thread) may be performed. In this method, one end of the thread is fixed to the game ball, the other end is held in the left hand, etc., and this game ball is fired as usual. When this game ball with a thread enters the winning opening and is detected by the ball sensor provided in the winning opening (the winning ball is paid out), the other end of the thread is pulled and is not detected by the ball sensor. The game ball is pulled out until the ball is loosened again, and the game ball is detected by the ball sensor (award ball is paid out). As a result, the ball sensor misrecognizes that a plurality of game balls have entered the winning slot, and gives a prize ball to the fraudster.

  In order to prevent such illegal acts, in Patent Document 1, a step is provided in the ball passage, and when the game ball descends the step (the normal flow direction of the game ball), the game ball is detected. When climbing (an abnormal flow direction of the game ball; suspected of fraud), the sensor detects that the game ball has hit the lever that protrudes from the wall part that constitutes the step and has displaced the lever. Thus, a technique for detecting fraud is disclosed. In addition, although the apparatus of patent document 1 is not a game machine but a pachinko ball counter, it is an invention related to measures against fraud similar to a game machine.

JP-A-10-85441

  However, there are other illegal acts using the threaded ball other than those described above. For example, another game ball is guided to a so-called warp route by positioning a ball with thread at a predetermined location in the game area. The warp route usually has an entrance formed on the left side surface of the center case surrounding the liquid crystal display device, and the game ball entered here is guided to a portion called a stage formed below the liquid crystal display device. The ball enters the starting port provided below the door with high probability. When the game ball enters the starting port, a random number is generated, and whether or not it is determined is determined based on the value of the random number. If the result of the determination is a win, a big hit game is generated, and a large number (for example, 1000 or more) prize balls are given to the player. Therefore, when the game ball is guided to the warp route, the random number is likely to be generated, and thereby a big hit game is also likely to be generated. A specific example of the “predetermined position” is the left side of the entrance of the warp route. By positioning the ball with the thread here, the game ball colliding with the ball with the thread is directed toward the entrance of the warp route. To do.

Further, as other illegal acts, a ball with a thread is used to obstruct the flow of the game ball in the game area, and a stay of game balls called grapes is generated. There is also an act of guiding other game balls to the starting port).
In any of these frauds, even if the ball with thread is detected by the ball sensor, it does not reciprocate before and after the ball sensor. Therefore, it is possible to prevent these frauds from being detected by the technique described in Patent Document 1. It is also difficult to do.
This invention is made | formed in view of the subject which concerns, and it aims at preventing the cheating using a ball | bowl with a thread | yarn.

The present invention according to claim 1, which has been made to solve the above-mentioned problems, includes a tray part for holding a game ball for launching into a game area, a game ball launching apparatus for launching a game ball into the game area, and the dish. A ball game machine comprising a game ball passage for guiding a game ball from a section to the game ball launching device, provided in the game ball passage, and when the game ball is threaded, The game ball passage is partly or entirely formed as a spiral passage, and the altitude is lowered while rotating the game ball along the spiral shape. The game ball launching device is guided to the game ball launching device, and is formed so that the diameter of the rotation becomes smaller as it goes down, and the cross section of the game ball passage allows the game ball to flow without stagnation. It is a circle that is small enough to The yarn launching preventing unit, characterized in that it comprises a spirally formed portion of said game ball passage.
That is, the game ball passage has a shape in which the passage is wound while changing the diameter like a shell of a conch shell. In addition, the direction of the rotation axis of the winding may be vertical, but may be tilted to such an extent that the game ball can flow down.

The present invention described in claim 2 is the ball-shooting game machine according to claim 1, wherein the thread firing prevention unit is characterized by being configured to be detachable from the bullet ball game machine.

  In the ball game machine according to the first aspect of the present invention, the ball launching portion is provided in the game ball passage for guiding the game ball from the plate portion to the game ball launching device. If the game ball guided along the game ball passage has a thread, the thread is entangled with the thread launch prevention unit, and this game ball cannot reach the game ball launching device and is not fired. . Thereby, the fraud using the ball with a thread as described above can be prevented.

A part or the whole of the game ball passage is formed as a spiral passage, and guides the game ball to the game ball launching device along the spiral shape. The yarn firing preventing portion includes a spirally formed portion of the game ball passage. That is, some or all of Yu skill ball passage is part of the thread firing prevention unit. When the game ball has a thread, the thread also flows down along this spiral shape, and as a result, the thread is wound around the spiral portion. Therefore, it is possible to realize a bullet ball game machine that can prevent an illegal act using a ball with a thread with a simple configuration. The state where the yarn is wound is also expressed as “the yarn is entangled” in the present invention.
The cross section of the game ball passage is a circular shape that is small enough to allow the game ball to flow without stagnation.

The diameter of the rotary is formed to be smaller as it goes to the bottom, the thread firing prevention part, it means that the helical portion formed rotates one revolution or more along the game balls in a spiral shape doing. When the thread attached to the game ball is rotated one or more times, the thread is firmly entangled, and it is possible to reliably prevent the thread from being fired together with the game ball .

In the gaming ball launching apparatus according to the second aspect , the yarn firing preventing portion is detachable from the bullet ball gaming machine. According to the gaming machine configured as described above, by removing the thread firing prevention unit from the gaming machine, the tangled thread can be easily removed, and the game can be resumed promptly.

Further, an external connection terminal board 78 is provided on the right side of the ball tank 71, and a signal indicating a game state and a game result is sent from the external connection terminal board 78 to a hall computer (not shown).

As shown in the block diagram of FIG. 4, the electrical configuration of the pachinko machine 50 is configured with a main controller 80 as a center. In this block diagram, a so-called relay board and power supply circuit for merely relaying signals are not described. Although not shown in detail, all of the main control device 80, the payout control device 81, the production symbol control device 82, and the sub integrated control device 83 include a CPU, a ROM, a RAM, an input port, an output port, and the like. However, in this reference example, the launch control device 84 is not provided with a CPU, ROM, or RAM. However, the present invention is not limited to this, and the launch control device 84 may be provided with a CPU, ROM, RAM, and the like.

  The main controller 80 includes a first start port switch 11a that detects a game ball that has entered the first start port 11, a second start port switch 12a that detects a game ball that has entered the second start port 12, and a gate. A normal symbol operation switch 17a for detecting a game ball that has entered 17; a first count switch 14a for counting game balls that have entered the grand prize opening 14, a first left prize opening 31, a second left prize opening 32; Detection signals such as a left winning port switch 31a for detecting a game ball that has entered the third left winning port 33 and the fourth left winning port 34 are input.

The main control device 80 operates in accordance with the installed program, generates various commands related to the progress of the game based on the above-described detection signals and outputs them to the payout control device 81 and the sub integrated control device 83.
Further, the main control device 80 includes a display of the special symbol display device 9 and the normal symbol display device 7 connected via the symbol display device relay terminal board 90, the special symbol hold number display device 18, and the normal symbol hold number display device. 8 is controlled.

  Further, the main controller 80 controls the opening / closing of the special winning opening 14 by controlling the special winning opening solenoid 14b, and controls the ordinary electric accessory solenoid (denoted as a general electric accessory solenoid in FIG. 4) 12b. Thus, the opening and closing of the second start port 12 is controlled. The output signal from the main controller 80 is also output to the test signal terminal, and management signals such as symbol fluctuations and big hits (also called special games) are sent to the back relay terminal board 75, the payout controller 81 and the external connection. It is sent to the hall computer 87 via the terminal board 78. The main control device 80 and the payout control device 81 can perform bidirectional communication.

The payout control device 81 operates the payout motor 20 in accordance with a command sent from the main control device 80 and pays out a prize ball. In this reference example, the detection signal of the payout sensor 21 for counting game balls to be paid out as prize balls is input to the payout control device 81, and the payout control device 81 counts the prize balls. In addition, it is also conceivable to use a configuration in which the detection signal of the payout sensor 21 is input to the main control device 80 and the payout control device 81 and the main control device 80 and the payout control device 81 count the prize balls.

  The payout control device 81 receives signals from the glass frame opening switch 35, the inner frame opening switch 36, the full switch 22, and the ball break switch 23, and a signal indicating that the lower plate 63 is full by the full switch 22. And when a signal indicating that there are few or no game balls in the ball tank is input by the ball break switch 23, the payout motor 20 is stopped and the payout operation of the prize ball is stopped. Note that the full switch 22 and the ball break switch 23 are also configured to continue outputting signals until the state is cleared, and the payout control device 81 causes the payout motor 20 to stop being output. Restart the drive.

  Also, the payout control device 81 operates the payout motor 20 by communicating with the CR unit 56 via the CR unit terminal plate 24, and discharges the rental balls. The paid-out lending ball is detected by the payout switch 21, and the detection signal is input to the payout control device 81. The CR unit terminal board 24 is also connected to the settlement display device 25 so as to be capable of two-way communication. The settlement display device 25 has a ball switch 57 for requesting a game ball to be rented, and a request for payment. A settlement switch 58 and a balance display 59 (see FIG. 1) are connected.

  Also, the payout control device 81 transmits information relating to the prize ball, information indicating the open / closed state of the frame (inner frame, front frame), etc. to the hall computer 87 via the external connection terminal board 78, and also to the launch control device 84. In response to this, a fire stop signal is transmitted. An output signal of the yarn fraud detection sensor 74 is input to the payout control device 81, which will be described later.

  The launch control device 84 controls the launch solenoid 30 to launch the game ball into the game area 3. Moreover, the launch control device 84 controls the ball feed solenoid 41 to supply game balls one by one to a launch pad (described later). In addition to the payout control device 81, the launch control device 84 receives a rotation amount signal from the launch handle 64 (see FIG. 1), a touch signal from the touch switch 28, and a launch stop signal from the launch stop switch 29.

  The rotation amount signal is output when the player operates the launch handle 64, the touch signal is output when the player touches the launch handle 64, and the launch stop switch signal is output by the player pressing the launch stop switch 29. Is output. If the touch signal is not input to the firing control device 84, the game ball cannot be fired. If the fire stop switch signal is input, the game ball cannot be fired even if the player touches the launch handle 64. It is like that.

  The sub-integrated control device 83 corresponds to the sub-control device, receives data and commands transmitted from the main control device 80, distributes them to data for effect display control, sound control and lamp control, The display control command and the like are transmitted to the effect design control device 82, and the sound control and lamp control are distributed to each control part (function unit as a sound control device and a lamp control device) included in the display control command 82. Then, the function unit as the sound control device controls the sound output from the speaker 66 by operating the sound LSI based on the data for sound control, and the function unit as the lamp control device converts the data for the lamp control. Based on the operation of the lamp driver, various LEDs and the lamp 26 are controlled. In addition, an effect button 67 and a jog dial 68 are connected to the sub integrated control device 83, and when the player operates these 67 and 68, a signal is input to the sub integrated control device 83.

Bi-directional communication is possible between the sub integrated control device 83 and the production symbol control device 82.
The effect symbol control device 82 displays the effect symbol display based on the data and commands received from the sub integrated control device 83 (both those transmitted from the main control device 80 and those generated by the sub integrated control device 83). The device 6 is controlled to display an effect image such as a pseudo symbol on the screen 6 a of the effect symbol display device 6.

  FIG. 5 shows how the game balls on the upper plate 55 are supplied to the launching device. FIG. 5B is a diagram in which the periphery of the upper plate 55 is enlarged and the lower side of the effect button 67 is seen through in the front view shown in FIG. FIG. 5A is a view taken in the direction of arrows AA in FIG. 5B, and FIG. In FIG. 5A as well, the periphery of the game ball 15 is clearly seen in order to clearly show the path of the game ball 15 after the inflow port 55a (game ball passage 42 described later). The game ball 15 that has been on the upper plate 55 flows from the middle of the bottom surface of the upper plate 55 to the right, turns left, flows in the back direction (upward in FIG. 5A), and further turns left from the inlet 55a. It is guided below the bottom surface of the upper plate 55 (in this figure, in the back direction). This flow is realized by the inclination of the flow path. From the inflow port 55a to the launching device 19, it is unitized as a yarn entanglement passage member 45 (details will be described later using FIG. 6), and the game ball passage 42 in the yarn entanglement passage member 45 has a cross section of the game ball 15 in cross section. It has a circular shape with a diameter slightly larger than the diameter, and is formed in a substantially spiral shape. The “slightly large diameter” refers to a small size that allows the game ball 15 to flow through the game ball passage 42 without any delay. The game ball 15 that has passed through the inflow port 55a turns left (see FIG. 5 (a)), enters a spiral path, and rotates in the clockwise direction along the path to lower the altitude. The launching device 19 is reached (see FIG. 5C). In FIG. 5 (a), only two game balls are shown in the game ball passage 42. However, when there is a sufficient number of game balls 15 in the upper plate 55, the game ball passage 42 has The game balls 15 are filled with no gaps.

  The thread winding passage member 45 is configured to be detachable from the upper plate 55 as shown in FIG. In the state of FIG. 6, the game ball passage 42 (not shown) is separated from the upper plate 55 together with the thread winding passage member 45, so it is difficult to supply the game ball to the launching device 19.

  An explanatory view of the firing handle 64 is shown in FIG. FIG. 7A shows a state in which the firing lever 37 is not rotated, and FIG. 7B shows a state in which the firing lever 37 is rotated. The launch handle 64 is provided with a launch lever 37 so as to be rotatable around a dome-shaped touch portion 38 fixed to the pachinko machine 50. The firing lever 37 is provided with a rib 39 (usually covered with the touch portion 38 and cannot be seen). When the firing lever 37 shown in FIG. 7A is not rotated, the rib 39 is fired. The stop button 40 is pressed. Thereby, the firing stop switch 29 is in the ON state, that is, the game ball 15 is not fired. When the firing lever 37 is rotated, the rib 39 is separated from the firing stop button 40, the firing stop switch 29 is turned off, and the firing solenoid 30 and the ball feed solenoid 41 start operating.

  An appearance of the launching device 19 is shown in FIG. FIG. 8A is a view of the launching device 19 as viewed from the front side of the pachinko machine 50, and FIG. 8B is a perspective view of the launching device 19. The ball feed solenoid 41 is provided inside the ball feed cassette 44 together with the ball feed lever 43, and when the ball feed solenoid 41 is operated (also referred to as “ON”), the ball feed lever 43 is pivoted around P. It is swung around. The firing solenoid 30 is provided on the back side of the launching device 19 as shown in FIG. 8 (b). When the firing solenoid 30 is operated, the hammer 46 is swung and placed on the launch table 47. Fire a game ball. Reference numeral 48 denotes an introduction port through which the game ball 15 guided from the upper plate 55 enters the ball feed cassette 44.

  The operation of the ball feed solenoid 41 is shown in FIG. 9A is a rear view of the ball feeding cassette 44 (viewed from the opposite direction to FIG. 8A), and FIGS. 9B and 9C are views of the front surface of FIG. 9A. FIG. 9B shows a state in which the ball feed solenoid 41 is in operation, and FIG. 9C shows a state in which the ball feed solenoid 41 is not in operation (also referred to as “OFF state” or simply “OFF”). .

  The ball discharge port 49 is an outlet of the game ball 15 that flows out from the ball feeding cassette 44 to the launch pad 47 (see FIG. 8B and the like), and has a substantially rectangular hole. The game ball 15 that has entered the ball feed cassette 44 from the introduction port 48 is swung counterclockwise about the position P as an axis when the ball feed solenoid 41 is operated as shown in FIG. 9B. The ball feed lever 43 enters the recess (see also FIG. 10). This is because the concave portion of the ball feed lever 43 and the position of the introduction port 48 are aligned. In the state of FIG. 9B, another game ball 15 may flow into the inlet 48 from the upper plate 55, but this is not shown in order to avoid complication. This state occurs when the upper plate 55 is empty.

  When the ball feed solenoid 41 is turned off from this state, the ball feed lever 43 returns to the original position as shown in FIG. 9C (specifically, swings clockwise around the position P), The concave portion of the ball feed lever 43 and the position of the ball discharge port 49 are aligned, and the game ball 15 rolls forward in the figure and flows out of the ball discharge port 49 and is placed on a launch pad 47 (not shown). In the state of FIG. 9 (c), the positions of the recess of the ball feed lever 43 and the ball discharge port 49 are shifted, so that even if the game ball 15 flows out of the ball discharge port 49, another game ball 15 is The ball feed lever 43 does not enter the recess and only one game ball 15 is placed on the launch pad 47. In the following description, it is indicated that the ball feeding lever 43 is in the posture of FIG. 9B (regardless of whether or not the game ball 15 is in the concave portion), as shown in FIG. Being in a posture (whether or not the game ball 15 is in the recess) is also referred to as a “down state”.

  FIG. 10 shows the ball feeding operation viewed from another direction. FIG. 10A shows the ball feed solenoid 41, the ball feed lever 43, the introduction port 48, the launch pad 47 and the like taken out from the state immediately after FIG. 9C, and the reverse direction (that is, the front side of the pachinko machine 50). ). The “immediate state” is a state in which the game ball 15 that has been in the recess 43a flows out to the launch pad 47 and the recess 43a is empty. Then, “another game ball 15” (hereinafter simply referred to as “game ball 15”) is supplied from the upper plate 55 to the introduction port 48. In FIG. 10A, the game ball 15 that has flowed out to the launch pad 47 is not shown.

  In the state of FIG. 10A, since the ball feed lever 43 is in a lowered state, the positions of the introduction port 48 and the recessed portion 43 a are shifted, and the game ball 15 in the introduction port 48 is located above the ball feed lever 43. It abuts and cannot enter the recess 43a. FIG. 10B shows a state in which the ball feed solenoid 41 is operated from this state. In the state of FIG. 10B, the ball feed lever 43 is raised, the positions of the introduction port 48 and the recess 43a are aligned, and the game ball 15 in the introduction port 48 enters the recess 43a. Although not depicted in FIG. 10B, even if the game ball 15 is present at the introduction port 48, the recess 43a of the ball feed lever 43 has a size that allows only one game ball 15 to enter. Two or more game balls 15 enter the recess 43 a and are not sent to the launch pad 47 by the ball feed lever 43.

  When the ball feed solenoid 41 is turned off from this state, the ball feed lever 43 is lowered as shown in FIG. 10C, the positions of the recess 43a and the ball discharge port 49 are aligned, and FIG. Thus, the game ball 15 in the recess 43 a is discharged to the launch pad 47.

  According to the pachinko machine 50 configured as described above, when the game ball 15 is threaded, the thread is wound around the thread winding path member 45 along the game ball path 42 of the thread winding path member 45. Then, even when the ball feed lever 43 is in the raised state (the state shown in FIG. 10B), the yarn prevents the game ball 15 from entering the recess 43a. Even if the game ball 15 enters the recess 43a due to some kind of bounce, the yarn prevents the game ball 15 with the thread from being discharged from the recess 43a to the launch pad 47. Therefore, the threaded ball is not fired into the game area 3, and illegal acts using the threaded ball can be prevented. Even if the game ball 15 is threaded, when the game ball passage 42 in the thread winding passage member 45 flows down, the ball with thread is pushed to the game ball 15 flowing down later, so that the ball is steady. It flows down the game ball passage 42 and reaches the launching device 19. That is, the yarn is wound along the game ball passage 42.

  Thus, when the yarn is wound around the yarn entanglement passage member 45 along the game ball passage 42 of the yarn entanglement passage member 45, the game ball 15 becomes unfireable and cannot play a game, but the entangled yarn is not entangled. 6 can be easily removed by removing it from the upper plate 55 as shown in FIG.

Here, the correspondence between the configuration of this reference example and the configuration requirements of the present invention is shown. The upper plate 55 corresponds to the “dish portion” of the present invention, the launching device 19 corresponds to the “game ball launching device” of the present invention, and the flow path from the inlet 55a to the launching device 19 is the “game ball” of the present invention. The yarn entanglement passage member 45 corresponds to the “thread firing prevention portion” of the present invention.
[ Example]

For real施例of the present invention will be described with reference to FIG. 11. Since the present embodiment has much in common with Reference Example 1, only different points will be described mainly.
FIG. 11 (b) is an enlarged view of the periphery of the upper plate 55, FIG. 11 (a) is an AA arrow view of FIG. 11 (b), and FIG. 11 (c) is a pachinko. It is the figure which made the machine 50 into a partial cross section and was seen from the right side of the upper plate 55.
Note that the same perspective as in FIG. 5 is also performed in FIG.

In the same manner as the yarn entanglement passage member 45 of the first reference example, the yarn entanglement passage member 45 of the present embodiment decreases as the diameter of the clockwise rotation decreases as the game ball rotates while rotating clockwise. A game ball passage 42 is formed as described above.
And also in this embodiment, the yarn entwined passage member 45 is detachably attached to the upper tray 55 (not shown. Similar to FIG. 6, can be removed upward direction).

Also with the pachinko machine 50 configured as described above, as with the pachinko machine 50 of the first reference example, when the game ball 15 is threaded, the thread is threaded along the game ball path 42 of the yarn entanglement path member 45. Even when the wrapping passage member 45 is wound and the ball feed lever 43 is in the raised state (the state shown in FIG. 10B), the yarn prevents the game ball 15 from entering the recess 43a. Even if the game ball 15 enters the recess 43a due to some kind of bounce, the yarn prevents the game ball 15 with the thread from being discharged from the recess 43a to the launch pad 47. Therefore, the threaded ball is not fired into the game area 3, and illegal acts using the threaded ball can be prevented.

When the yarn is wound around the yarn entanglement passage member 45 along the game ball passage 42 of the yarn entanglement passage member 45 in this manner, the game ball 15 becomes unfireable and cannot play a game. It can be easily removed by removing it from the upper plate 55 as described above.
[ Reference Example 2 ]

A second reference example of the present invention will be described with reference to FIGS. Since this reference example has much in common with Reference Example 1, only the different points will be described mainly. FIG. 12 (b) is an enlarged view of the periphery of the upper plate 55, FIG. 12 (a) is an AA arrow view of FIG. 12 (b), and FIG. 12 (c) is a pachinko. It is the figure which made the machine 50 into a partial cross section and was seen from the right side of the upper plate 55. Note that the same perspective as in FIG. 5 is also performed in FIG.

The yarn entanglement passage member 45 of the second reference example has a game ball passage 42 that descends while the game ball rotates clockwise, although the diameter is slightly smaller than the game ball passage 42 of the first reference example, but is substantially the same. Is formed. The major difference from the first reference example is the ball feeding mechanism. That is, in the first reference example, the ball feeding lever 43 is swung in the launching device 19 to supply the game balls one by one to the launch pad 47. However, in the second reference example, the yarn entanglement is performed. A ball feeding mechanism is provided inside the passage member 45, and the launching device 19 feeds the game ball 15 flowing from the introduction port 48 to the launching stand 47 as it is. For this reason, the launcher does not include the ball feed solenoid 41 and the ball feed lever 43, and the introduction port 48 and the ball discharge port 49 are directly connected (not shown).

An outline of the ball feed mechanism of the second reference example is shown in FIG. 13 (a) to 13 (c) are views of the yarn winding passage member 45 as viewed from above the pachinko machine 50. As shown in this figure, in the second reference example, the yarn winding passage member 45 is shown. Includes a ball feed solenoid 41. A game ball holding portion 91 having a circular hole whose cross section is slightly larger than the diameter of the game ball 15 is fixed to the plunger of the ball feed solenoid 41. This hole is provided with an inclination so that the left side is lower than the right side in the figure. When the ball feed solenoid 41 is driven, the cross section near the inflow port 55a and the cross section of the game ball holding portion 91 are aligned as shown in FIG. 13A, and the game ball 15 flows into the game ball holding portion 91. Note that the width of the game ball holding portion 91 is slightly larger than the diameter of the game ball 15, so that only one game ball 15 can enter the game ball holding portion 91 at most. In the state of FIG. 13A, the cross section of the introduction portion (near the game ball holding portion 91) 42a of the game ball passage 42 and the cross section of the game ball holding portion 91 are not aligned, and the inside of the game ball holding portion 91 The game ball 15 abuts against the edge of the introduction portion 42 a and does not flow out to the game ball passage 42.

  When the excitation of the ball feed solenoid 41 is released from the state of FIG. 13A, the plunger moves downward in the figure. FIG. 13B shows the state immediately after that. In this state, the cross section of the introduction part 42a and the cross section of the game ball holding part 91 are aligned. On the other hand, the cross section near the inflow port 55a and the cross section of the game ball holding portion 91 are not aligned.

  Since the hole formed in the game ball holding portion 91 is lower on the left side than the right side in the drawing as described above, if the cross section of the introduction portion 42a and the cross section of the game ball holding portion 91 are aligned, the game The game ball 15 in the ball holding portion 91 flows out to the game ball passage 42 due to the inclination of the hole. This is shown in FIG. 13 (c). In this state, the cross section in the vicinity of the inflow port 55a and the cross section of the game ball holding portion 91 are not aligned, so that the game ball 15 does not flow into the game ball holding portion 91 anew. When the ball feed solenoid 41 is excited, the state returns to the state of FIG. 13A and the game ball 15 flows into the game ball holding portion 91. Therefore, by repeating the excitation / release of the excitation of the ball feed solenoid 41, the game balls 15 are supplied one by one to the game ball passage 42 and eventually to a launching device (not shown).

  A signal for driving the ball feed solenoid 41 is transmitted from the firing control device 84. The yarn winding passage member 45 and the firing control device 84 are electrically connected by a harness connected to a connector included in each of them, and the yarn winding passage member 45 can be obtained without any trouble by giving a margin to the length of the harness. Is configured to be removable from the upper plate 55.

Similarly to the pachinko machine 50 of the first reference example, the pachinko machine 50 configured as described above also winds the yarn along the game ball passage 42 of the yarn entanglement passage member 45 when the game ball 15 is threaded. Therefore, the ball with thread is not fired into the game area 3, and illegal acts using the ball with thread can be prevented. Unlike the first reference example and the actual施例, since game balls 15 in the game ball holding portion 91 is never pushed subsequent game ball 15, when the yarn is attached to the game ball 15 The thread may inhibit the game ball 15 from flowing out from the game ball holding portion 91 to the game ball passage 42. Also in this case, since the threaded ball is not fired as a result, an illegal act using the threaded ball can be prevented.

Further, since the ball feeding mechanism exists upstream of the game ball passage 42, the next game ball 15 does not flow into the game ball passage 42 for a predetermined time after the game ball 15 flows into the game ball passage 42. This predetermined time is about 0.6 seconds at the shortest because the firing frequency of the game balls 15 is 100 or less per minute. Therefore, weakened about pushed subsequent game ball 15 in the yarn with the ball game ball passage 42 as compared to the first exemplary embodiment and the examples, thereby also the thread with ball stays in the game ball passage 42 Conceivable. Also in this case, since the threaded ball does not reach the launching device 19, it is not fired, and an illegal act using the threaded ball can be prevented.

In this case, in order to remove the entangled yarn, it is conceivable to open the front frame 52 to expose the back side of the upper plate 55 and cut the yarn using a tool such as scissors.
