Description

  The present invention relates to a gaming machine, and more particularly, to a gaming machine that performs a game by circulating a game medium.

  In recent years, in the field of gaming machines, various techniques have been proposed for preventing such malfunctioning, focusing on the point that malfunctions of the gaming machine may occur due to static electricity charged on the game medium reaching the control board. For example, in a pachinko game machine using a game ball as a game medium, static electricity charged on an outer rail or the like is guided to a ground processing unit through a lead wire, and the static electricity on the rail is transmitted to the outside of the game machine (hereinafter referred to as “outside the machine”). The removal method (for example, see Patent Literature 1), the handle and the ball tray are formed of plastic mixed with carbon-based ultrafine fibers, and the static electricity generated on the handle and the ball tray is neutralized in the air to be out of the machine. (See, for example, Patent Document 2). As described above, conventionally, malfunction of the gaming machine has been prevented by removing static electricity that may reach the control board to the outside of the machine.

JP-A-5-228257 JP-A-6-15059

  However, in a gaming machine, static electricity is frequently generated due to collision between game media in the game medium flow path and friction between the game medium and a member forming the game medium flow path. It is difficult to perform the operation, and there is a possibility that the static electricity remaining inside the device may act as a source of noise for the control board. On the other hand, no means has been proposed for reducing the probability that the static electricity acts as noise on the control board when the static electricity reaches the control board.

  Therefore, the present invention solves the above-described problems, and adopts the following configuration in an amusement machine for the purpose of ensuring normal operation processing by the control board even when static electricity reaches the control board. Was.

The gaming machine of the present invention,
A gaming machine for playing games by distributing gaming media,
A game medium flow path, which is a path through which the game medium flows,
A control board for controlling the operation related to the game,
The gist of the invention is that the control board is arranged such that a conductor pattern on at least one side of the control board is in a direction along a flowing direction of the game medium in the game medium flow passage.

  As the game medium in the above invention, for example, a game ball or a game metal can be considered.

  According to the gaming machine of the invention described above, the control board is disposed such that the conductor pattern on at least one side of the control board is in a direction along the flowing direction of the game medium in the game medium flow passage. By adopting such a configuration, the probability that static electricity charged near the game medium flow path acts as noise on the control board is greatly reduced. Therefore, it is possible to ensure a normal processing operation of the control board, and it is possible to effectively prevent a malfunction in the gaming machine.

  It is also preferable that the conductor pattern that is oriented in the game medium flow path along the flowing direction of the game medium is a signal line that is a conductor pattern for transmitting an electric signal.

  It is also desirable to provide a covering member that covers the control board in that noise hardly reaches the control board. It is also preferable that the covering member is formed of a transparent and non-conductive material. In this case, the static electricity is more easily charged on the covering member, but since the control board is disposed in the direction along the flowing direction of the game medium in the game medium flow passage, the control board is charged with the charged static electricity. Less susceptible to Therefore, both the visibility of the state of the control board from the outside and the normal processing operation of the control board can be realized.

  Further, the game medium flow passage may be formed using a synthetic resin. In this case, static electricity is more likely to be charged in the vicinity of the game medium flow path, but since the control substrate is disposed in a direction along the flow direction of the game medium in the game medium flow path, the control substrate is charged. Less susceptible to static electricity. Therefore, it is possible to secure both the ease of forming the game medium flow passage and the normal processing operation of the control substrate.

In FIG. 2, the positions of the control boards 57a, 58a, 81a, 82a, 84a, 86a on the back surface of the mechanism plate 70 are indicated by two-dot chain lines, and the mechanism plate hinges 71, 79 are omitted.

  As shown in FIGS. 1 and 2, the guide path 70 b is formed by penetrating the mechanism plate 70 at a position facing the first outlet of the bell tub base 77 in the width direction. The branch path 70c is provided by forming a groove serving as a path for the game ball B on the surface of the mechanism plate 70 located below the second exit of the bell base 77. The groove portion includes a vertical groove 70ct extending substantially vertically downward, and a horizontal groove 70cy continuing from the vertical groove 70ct and extending substantially horizontally obliquely downward from the extension end of the vertical groove 70ct. . The ball discharge passage 70d is provided on the surface of the mechanism plate 70 located below the out port 53 with a guide groove 70dg extending substantially obliquely downward, and continuous with the guide groove 70dg, from the extension end of the guide groove 70dg. It is provided by forming a flow-down groove 70dk extending substantially vertically downward.

  Next, a distribution route of the game balls B in the pachinko gaming machine 10 will be described with reference to FIG. FIG. 3 is an explanatory view schematically showing the mechanism plate 70 as viewed from the back of the pachinko gaming machine 10. In FIG. 3, the distribution route of the game balls B is indicated by using thick black arrows.

  As shown in FIG. 3, the game ball B supplied from the ball supply device of the game arcade is provided with a tank rail 73, a case rail 74, and a prize ball / lending from a ball tank 72 mounted on the back of the mechanism plate 70. It sequentially flows to the ball payout unit 75. The game ball B that has flowed into the prize ball / ball rental unit 75 is blocked when the game ball B has entered the sprocket by the cylindrical member in a rotation stopped state when the ball is not lent or won. Can be Thus, the game balls B are stored in the ball tank 72, the tank rail 73, the case rail 74, and the prize ball / ball rental unit 75.

  On the other hand, when the game ball B enters the normal winning opening 43 or the special winning opening 46 during the game, the main control unit 84 and the payout control unit 86 which detect the entry of the game ball B drive the winning ball side motor. Instruct. Thus, the cylindrical member connected to the prize ball side motor rotates, and the game balls B in the sprocket are sequentially sent out into the bell base 77 with the rotation of the cylindrical member. As shown in FIG. 3, the game balls B sent out into the bell base 77 flow down while colliding with the bell in the passage inside the bell base 77, and are discharged from the first exit to the guide path 70b. Thereby, a predetermined number of gaming balls B as prize balls are paid out to the upper plate on the front side of the pachinko gaming machine 10 through the guide path 70b.

  As shown in FIG. 3, the game ball B which has entered the normal winning opening 43, the special winning opening 46, and the out opening 53 (hereinafter, referred to as the game ball B which has entered the game area) is, as shown in FIG. After flowing down to the surface of the ball 70, it joins the ball discharge passage 70d described above. Thereafter, the game ball B slowly flows down along the slope of the guide groove 70dg of the ball discharge passage 70d, and then flows down substantially vertically along the flow-down groove 70dk. Thereby, the game ball B that has entered the game area is discharged to the outside of the pachinko gaming machine 10. In FIG. 3, the flow path of the game ball B in a substantially horizontal obliquely downward direction formed by the guide groove 70dg of the ball discharge path 70d is shown as a flow area H1.

  When the game balls B exceeding the capacity of the upper plate are paid out, the guide path 70b and the first exit are closed by the game balls B. After the first exit is closed, the game balls B in the bell base 77 flow toward the second exit, and are discharged from the second exit to the branch path 70c. The game ball B discharged to the branch path 70c flows down along the vertical groove 70ct of the branch path 70c, and then gradually flows down along the inclination of the horizontal groove 70cy. Thereby, the game balls B exceeding the capacity of the upper plate are paid out to the lower plate on the front side of the pachinko gaming machine 10 through the branch path 70c. In FIG. 3, the flow path of the game ball B in a substantially vertically downward direction from the entrance of the bell tub base 77 to the end of the vertical groove 70ct of the branch path 70c is shown as a flow area H2, and the horizontal groove of the branch path 70c. The flow path of the game ball B extending substantially horizontally obliquely downward from the start end to the end of 70cy is shown as a flow area H3.

  Further, when the lending button of the guide unit is pressed after the prepaid card is inserted into the prepaid card unit 15, the main control unit 84 and the payout control unit 86 which have detected the information on the number of balls to be lent are connected to the motor of the ball rental side motor. Instructs driving. As a result, the cylindrical member connected to the ball-lending side motor rotates, and the gaming ball B from the prize-ball / ball-lending payout unit 75 is passed from the suzuki base 77 to the pachinko gaming machine through the guide path 70b, as in the case of winning. 10 Dispensed to the upper plate on the front side.

  With the payout of the prize balls and the ball rental, the game balls B stored in the case rail 74, the tank rail 73, and the ball tank 72 sequentially move toward the prize ball / ball rental payout unit 75. When it is detected that the number of balls stored in the ball tank 72 is equal to or less than a certain number by paying out the prize balls or the lending balls, the game is performed based on the instruction from the frame external terminal plate 80d receiving the detection result. Game balls B are supplied to the ball tank 72 from the ball supply device of the field.

  The number of paid-out spheres and ball-for-lending is detected by a prize-ball / ball-for-lending sensor (not shown) provided in the prize-ball / ball-for-lending payout unit 75. When the prize ball / ball lending sensor detects a predetermined number of payouts, it sends a detection result to the payout control unit 86, and upon receiving the detection result, the payout control unit 86 stops driving the motor on the prize ball side or the ball rental side. Instruct. Thus, the rotation of the cylindrical members connected to the respective motors is stopped, and the feeding of the game balls B to the bell base 77 by the sprockets of the cylindrical members is stopped. As a result, the ball tank 72, the tank rail 73, and the case rail 74 return to the state in which the game balls B are stored as before the winning or ball lending.

  As shown by the two-dot chain line in FIG. 3, on the back surface of the mechanism plate 70, the power supply board 81a, the emission control board 82a, and the main board 84a are formed in the flow area H1 formation area, and the payout control board 84a is formed in the flow area H2 formation area. The power supply board 81a is disposed in the range in which the flow region H3 is formed. Each of the control boards 81a, 82a, 84a, 86a is a double-sided printed circuit board, and is electrically connected to a front surface on which electronic components are mounted (hereinafter, referred to as a front surface) via through holes. (Hereinafter referred to as a back side surface). 1 and 3, each of the control boards 81a, 82a, 84a, 86a is disposed such that the back side surface of the board and the back side of the mechanism plate 70 face each other.

  FIG. 4 shows a back side surface of the main board 84a. As shown in FIG. 4, on the back side of the main substrate 84a having a horizontally long rectangular shape, a power supply line DL for supplying power required for processing operations performed on the substrate, and various controls and processing contents are defined. A conductor pattern such as a signal line SL for transmitting an electric signal, a power line DL, and a ground line GL which is a reference potential region connected to the signal line SL is printed thereon. In FIG. 4, the power supply line DL and the signal line SL are shown using a thick black line and a thin black line, respectively. In FIG. 4, white portions, black circle portions, and hatched portions represent terminals connected to the ground line GL, the power supply line DL and the signal line SL, and a glass epoxy substrate on which a conductor pattern is printed. Note that, although the above-described base material is actually exposed also in the peripheral region of each power supply line DL and each signal line SL, the hatched portion of the peripheral region is omitted in FIG.

  As shown in FIG. 4, the power supply line DL, the signal line SL, and the ground line GL extend in a direction substantially parallel to the long side of the main substrate 84a.

  FIG. 5 is a schematic diagram showing a positional relationship between the conductor pattern and the flow region H1 when such a main substrate 84a is disposed at a predetermined position on the mechanism plate 70 (the position shown in FIG. 3). In FIG. 5, the guide groove 70dg is indicated by a two-dot chain line, and the mechanism plate 70, the power supply / emission control board plate 83, the emission control board 82a, and the resin cover 82w interposed between the guide groove 70dg and the main board 84a. , The power supply board 81a, the resin cover 81w, and the main board plate 85 are omitted. Further, in FIG. 5, the base material exposed around the power supply line DL and the signal line SL is indicated by a white portion, and the ground line GL is indicated by using a dot pattern hatching.

  As shown in FIG. 5, when the main board 84a is provided on the mechanism plate 70, the power line DL, the signal line SL, and the ground line GL on the back side of the main board 84a are moved in the flow direction of the game ball B in the flow area H1. The direction is substantially parallel to the direction (indicated by the arrow P in FIG. 5), and is a direction along the flowing direction of the game ball B in the flowing area H1.

  A conductor pattern is also printed on the back side of the power supply board 81a, the emission control board 82a, and the payout control board 86a in the same form as the main board 84a. Therefore, when the power supply board 81a and the firing control board 82a are disposed at predetermined positions (the positions shown in FIG. 3) of the mechanism plate 70, the power supply line DL, the signal line SL, and the ground line GL on the rear side of the power supply board 81a. Is the direction along the flow direction of the game ball B in the flow area H1 and the flow area H3, and the power line DL, the signal line SL, and the ground line GL on the back side of the firing control board 82a are the flow direction of the game ball B in the flow area H1. Along the direction.

  FIG. 6 is a schematic diagram showing the positional relationship between the conductor pattern and the flow area H2 when the payout control board 86a is disposed at a predetermined position on the mechanism plate 70 (the position shown in FIG. 3). In FIG. 6, the bell base 77 and the vertical groove 70ct are shown by two-dot chain lines, and the description of the mechanism plate 70 and the payout control board plate 87 interposed between the vertical groove 70ct and the payout control board 86a is omitted. Is shown. In FIG. 6, the base material exposed around the power supply line DL and the signal line SL is indicated by a white portion, and the ground line GL is indicated by using a dot pattern.

  As shown in FIG. 6, when the payout control board 86a is disposed on the mechanism plate 70, the power supply line DL, the signal line SL, and the ground line GL on the back side surface of the payout control board 86a are connected to the game ball B in the flow area H2. It becomes substantially parallel to the flowing direction (the direction indicated by arrow Q in FIG. 6), and is a direction along the flowing direction of the game ball B in the flowing area H2.

  As described above, by setting the conductor pattern on the back surface of each control board 81a, 82a, 84a, 86a to be in the direction along the flow direction of the game ball B in the flow areas H1 to H3, each control board 81a, 82a, 84a and 86a are less susceptible to electrostatic noise than in the prior art. This is because static electricity is charged at various potentials in the vicinity of the branch path 70c and the ball discharge path 70d of the mechanism plate 70 due to the flow of the game ball B, and this static electricity is guided to the back side of each control board 81a, 82a, 84a, 86a. In such a case, the induced static electricity flows along each power supply line DL, signal line SL, and ground line GL based on the difference in potential, so that each of the conductor patterns on the back side surface of each control board 81a, 82a, 84a, 86a It is considered that this is caused by the fact that the potential difference hardly occurs in the above. If a potential difference is hardly generated between the conductor patterns, noise is hardly generated on the back side of each control board 81a, 82a, 84a, 86a, and noise is emitted from the back side of each control board 81a, 82a, 84a, 86a. This is because the likelihood and the likelihood that this emission noise will reach each control board 57a, 58a, 81a, 82a, 84a, 86a are reduced.

  In the pachinko gaming machine 10 described above, the conductor pattern on the back side of each of the control boards 81a, 82a, 84a, and 86a is set in the direction along the flowing direction of the game ball B, and the ball tank 72, The tank rail 73, the case rail 74 and the prize ball / ball rental payout unit 75 are formed by using resin conductive materials having different surface resistance values, and the static electricity charged in the ball tank 72 and the like is discharged outside the machine via the metal plate 90. And a configuration for removing static electricity charged on the firing rail, inner rail, outer rail, and the like to the outside of the machine, a power supply / emission control board plate 83, a main board plate 85, a payout control board plate 87, and a lamp. A configuration is adopted in which the respective plates, that is, the sound board plate 59 are connected to each other. The result of measuring the effect of noise due to static electricity during the game in such a pachinko gaming machine 10 is shown in the graph of FIG.

  FIG. 7 is a graph showing a potential difference generated in a pachinko gaming machine before and after paying out award balls and lending balls. In this graph, a change in the potential difference in the power supply line is sampled as data. The vertical axis indicates the potential difference, and the horizontal axis indicates the elapsed time. FIG. 7A shows a measurement result of the conventional pachinko gaming machine, and FIG. 7B shows a measurement result of the pachinko gaming machine 10 of the present embodiment. As shown in FIG. 7, before a prize ball or a lending ball is paid out, the potential difference in the power supply line is stable at around 5 volts.

  As can be seen by comparing FIG. 7 (A) and FIG. 7 (B), in the conventional pachinko game machine, when paying out prize balls or lending balls, the maximum is 11 volts and the minimum is -2. A voltage difference of volts occurs, and the width W2 at which the voltage changes is 13 volts. On the other hand, in the pachinko gaming machine 10 of the present embodiment, when a prize ball or a rental ball is paid out, a potential difference of 6 volts at the maximum and 4 volts at the minimum occurs, and the width W1 at which the voltage changes is 2 volts. It becomes. As described above, in the pachinko gaming machine 10 according to the present embodiment, the width of the change in the voltage of the power supply line at the time of paying out a prize ball or a lending ball is limited to about ± 1 volt, and is about １ ／ of the conventional pachinko gaming machine Is reduced to From the above, it can be seen that in the pachinko gaming machine 10 of the present embodiment, noise due to static electricity caused by payout of prize balls, payouts of balls, and the like is less likely to be on the power supply line than in conventional products.

  In the pachinko gaming machine 10 of the present embodiment described above, each control board 81a, 82a, 84a, 86a is set so that the conductor pattern on the back side of the board is in the direction along the flow direction of the game balls B in the flow areas H1 to H3. To be installed in This greatly reduces the probability that static electricity charged near the flow regions H1 to H3 acts as noise on the control boards 57a, 58a, 81a, 82a, 84a, 86a. Therefore, it is possible to ensure a normal processing operation of each of the control boards 57a, 58a, 81a, 82a, 84a, 86a, and it is possible to effectively prevent a malfunction in the pachinko gaming machine 10.

  In particular, in this embodiment, since the branch path 70c and the ball discharge path 70d located in the flow regions H1 to H3 are formed using synthetic resin, more static electricity is charged in the vicinity of the branch path 70c and the ball discharge path 70d. The control boards 81a, 82a, 84a, and 86a are arranged so as to be in the direction along the flowing direction of the game ball B, so that the control boards 81a, 82a, 84a, and 86a are branched. 70c, and becomes less susceptible to static electricity charged near the ball discharge passage 70d. Therefore, it is possible to secure both the ease of forming the branch path 70c and the ball discharge path 70d and the normal processing operation of the control boards 81a, 82a, 84a, 86a.

  In the present embodiment, the signal lines SL on the back side of the main board 84a and on the back side of the payout control board 86a are set to the direction along the flow direction of the game balls B in the flow areas H1 and H2. Therefore, an electric signal for paying out the game ball B flows to the signal line SL of the main board 84a or the payout control board 86a due to the static electricity charged in the vicinity of the flow area H1 or H2. Nevertheless, a situation in which the game balls B are paid out can be effectively prevented.

  Further, in the above embodiment, the main control unit 84 having the main substrate 84a is mounted so as to cover the power supply unit 81 and the firing control unit 82 mounted on the rear surface of the mechanism plate 70, and the mechanical plate in which the ball discharge passage 70d is formed. The main board 84a is arranged in a state separated from the main board. Similarly, in the above embodiment, the mechanism in which the dispensing control unit 86 having the dispensing control board 86a is mounted so as to cover the power supply unit 81 and the bell tub cover 78 mounted on the back of the mechanism plate 70, and the branch path 70c is formed. The dispensing control board 86a is arranged in a state where the dispensing control board 86a is separated from the plate 70 and the bell base 77. For this reason, the static electricity charged in the stub base 77, the branch path 70c, and the ball discharge path 70d is less likely to reach the main board 84a and the payout control board 86a because of the stub cover 78 and the resin covers 81w and 82w. Therefore, the normal processing operation of the main board 84a and the payout control board 86a can be more fully ensured.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can be implemented in various modes without departing from the gist of the invention.

  For example, in the above embodiment, each of the control boards 81a, 82a, 84a, 86a is connected to the path of the game ball B (the path in the flow area H1) in which the conductor pattern on the back side of the board is formed by the guide groove 70dg of the ball discharge path 70d. ), The path of the game ball B formed by the vertical groove 70ct of the stub base 77 and the branch path 70c (the path in the flow area H2), and the path of the game ball B formed by the horizontal groove 70cy of the branch path 70c (the flow area H3). The control boards 81a, 82a, 84a, 86a are arranged so that the conductor pattern on the back side of the board is in a direction along the path of the game ball B other than the above. It is also possible to arrange. As such a path of the game ball B, a path of the game ball B formed by the tank rail 73 and the case rail 74 can be considered.

  In the above-described embodiment, the main board 84a and the payout control board 86a are arranged in a positional relationship separated from the rear surface of the mechanism plate 70.
