A tulip-shaped accessory (ordinary electric accessory) is provided, and a second starting prize opening is formed as a starting region (second starting region).

  As an example, in the normally variable winning ball apparatus 6B, the movable wing piece is in the vertical position when the solenoid 81 for the normal electric accessory is in the OFF state, so that the game ball passes (enters) the second starting winning opening. It is difficult to open normally. On the other hand, in the normal variable winning ball apparatus 6B, the game ball passes through the second start winning opening by the tilt control in which the movable blade piece is tilted when the solenoid 81 for the normal electric accessory is in the ON state ( It will be in an expanded open state that is easy to enter.

  A game ball that has passed (entered) the first start winning opening formed in the normal winning ball apparatus 6A is detected by, for example, a first start opening switch 22A shown in FIG. A game ball that has passed (entered) a second start winning opening formed in the normal variable winning ball apparatus 6B is detected by, for example, a second start opening switch 22B shown in FIG. Based on the detection of the game ball by the first start port switch 22A, a predetermined number (for example, three) of game balls are paid out as prize balls, and the first special figure holding memory number is set to a predetermined upper limit value (for example, “ 4 ") If the following, the first start condition is satisfied. Based on the detection of the game ball by the second start port 22B, a predetermined number (for example, three) of game balls are paid out as prize balls, and the second special figure holding memory number is set to a predetermined upper limit value (for example, “ 4 ") If the following, the second start condition is satisfied. The number of prize balls to be paid out based on the detection of the game ball by the first start port switch 22A and the number of prize balls to be paid out based on the detection of the game ball by the second start port switch 22B.

Make it impossible. On the other hand, in the special variable winning ball apparatus 7, when the solenoid 82 for the big prize opening door is in the ON state, the big winning opening door opens the big winning opening and the game ball passes through the big winning opening (entrance). ) Make it easier. In this way, the special winning opening as a specific area changes into an open state in which a game ball easily passes (enters) and is advantageous to the player, and a closed state in which the game ball cannot pass (enters) and is disadvantageous to the player To do. Instead of the closed state where the game ball cannot pass (enter) through the big prize opening, or in addition to the closed state, a partially opened state where the game ball hardly passes (enters) through the big prize opening may be provided.

  The game ball that has passed (entered) through the big prize opening is detected by, for example, the count switch 23 shown in FIG. Based on the detection of game balls by the count switch 23, a predetermined number (for example, 15) of game balls are paid out as prize balls. In this way, when the game ball passes (enters) through the large winning opening opened in the special variable winning ball apparatus 7, the gaming ball passes through other winning openings such as the first starting winning opening and the second starting winning opening, for example. More prize balls are paid out than when passing (entering). Accordingly, when the special winning ball apparatus 7 is in the open state, the game ball can enter the special winning hole, which is advantageous to the player. On the other hand, when the special prize winning device 7 is closed in the special variable prize winning ball device 7, it becomes impossible or difficult for the player to get a prize ball by passing (entering) the gaming ball into the special prize winning port. This is a disadvantageous second state.

At this time, if a specific normal symbol (symbol per symbol), such as a number indicating “7”, is stopped and displayed as the fixed normal symbol, the fluctuation display result of the normal symbol becomes “per symbol”. On the other hand, if a normal symbol other than the symbol per symbol, such as a number or symbol other than the number indicating “7”, is stopped and displayed as the fixed ordinary symbol, the fluctuation display result of the normal symbol is “usually lost”. Become. Corresponding to the fact that the variation display result of the normal symbol is “per normal”, the expansion / release control (tilt control) is performed in which the movable wing piece of the electric tulip constituting the normal variable winning ball apparatus 6B is tilted. The normal opening control is performed to return to the vertical position when a predetermined time has elapsed.

  After the first start condition is satisfied, for example, when the game ball that has passed (entered) the first start winning opening formed in the normal winning ball apparatus 6A is detected by the first start opening switch 22A shown in FIG. Based on the fact that the first start condition is satisfied, for example, because the previous special figure game or the big hit gaming state has ended, the special figure game by the first special symbol display 4A is started. Further, the second starting condition is satisfied, for example, when a game ball that has passed (entered) the second starting winning opening formed in the normally variable winning ball apparatus 6B is detected by the second starting opening switch 22B shown in FIG. Later, based on the fact that the second start condition is satisfied, for example, due to the end of the previous special game or the big hit gaming state, the special game by the second special symbol display 4B is started.

  In the special symbol game by the first special symbol display 4A or the second special symbol indicator 4B, after the special symbol variation display is started, when the variation display time as the special symbol variation time elapses, the special symbol variation display is performed. The resulting definite special symbol (special diagram display result) is derived and displayed. At this time, if a specific special symbol (big hit symbol) is stopped and displayed as a confirmed special symbol, it becomes a “big hit” as a specific display result, and if a special symbol different from the big bonus symbol is stopped and displayed as a fixed special symbol, “ It will be “losing”. In addition, a predetermined special symbol (small hit symbol) different from the big hit symbol may be stopped and displayed. When the predetermined special symbol (small hit symbol) as a result of the predetermined display is stopped and displayed. What is necessary is just to control to the small hit game state as a special game state different from the big hit game state.

  After the fluctuation display result in the special figure game becomes “big hit”, the game is controlled to the big hit gaming state as a specific gaming state in which a round advantageous to the player (also referred to as “round game”) is executed a predetermined number of times.

  In the pachinko gaming machine 1 according to the present embodiment, as an example, special symbols indicating numbers “3”, “5”, and “7” are jackpot symbols, and a special symbol indicating a symbol “−” is a lost symbol. When the small hit symbol is stopped and displayed, for example, a special symbol indicating the number “2” may be used as the small hit symbol. It should be noted that each symbol such as a jackpot symbol or a lost symbol in the special symbol game by the first special symbol display 4A may be different from each symbol in the special symbol game by the second special symbol display 4B. However, a special symbol common to both special symbol games may be a jackpot symbol or a lost symbol.

  After the jackpot symbol indicating the numbers “3”, “5”, and “7” as the special symbols for the special figure game is stopped and displayed as the “big hit” as the specific display result, it is specially variable in the jackpot game state. In a period until a predetermined upper limit time (for example, 29 seconds or 0.1 second) elapses or a period until a predetermined number (for example, 9) of winning balls is generated in the big winning door of the winning ball apparatus 7 , Open the grand prize opening. Thereby, the round which makes the special variable winning ball apparatus 7 the 1st state (open state) advantageous for a player is performed.

  A special prize-winning ball device that receives a game ball falling on the surface of the game board 2 and then closes the big prize-winning slot, with the grand prize-winning door that has opened the grand prize-winning port during the round. 7 is changed to the second state (closed state) disadvantageous to the player, and one round is completed. The round that is the opening cycle of the big prize opening can be repeatedly executed until the number of executions reaches a predetermined upper limit number (for example, “16”, etc.). Even before the number of rounds has reached the upper limit, the execution of the round may be terminated when a predetermined condition is satisfied (for example, a game ball has not won a big prize opening). .

  Of the rounds in the big hit gaming state, the round in which the upper limit time for which the special variable winning ball apparatus 7 is in the first state (open state) advantageous for the player is relatively long (for example, 29 seconds) is normally opened. Also called round. On the other hand, a round in which the upper limit time during which the special variable winning ball apparatus 7 is in the first state (open state) is relatively short (for example, 0.1 seconds) is also referred to as a short-term open round.

  When the small hit symbol (for example, the number “2”) is stopped and displayed, after the small hit symbol is derived as a confirmed special symbol, the small hit symbol is controlled as a special gaming state. good. Specifically, in the small hit game state, for example, the special variable winning ball apparatus 7 is advantageous to the player in the special variable winning ball apparatus 7 as in the above-described short-term open big hit state in which a practically no outgoing ball (prize ball) is obtained. The variable winning operation for changing to the first state (open state) may be executed.

  In the “left”, “middle”, and “right” effect symbol display areas 5L, 5C, and 5R provided in the image display device 5, a special symbol game using the first special symbol in the first special symbol display 4A and In response to the start of any one of the special figure games using the second special figure in the second special symbol display 4B, the variation display of the effect symbols is started. The period from the start of the variation display of the effect symbols to the end of the variation display due to the stop display of the confirmed effect symbols in the “left”, “middle”, and “right” effect symbol display areas 5L, 5C, 5R Then, the variation display state of the effect symbol may be a predetermined reach state.

  Here, the reach state refers to an effect design ("reach fluctuation design") that is not yet stopped when the effect design stopped and displayed in the display area of the image display device 5 constitutes a part of the jackpot combination. Is also a display state in which the fluctuation continues, or a display state in which all or part of the design symbols change synchronously while constituting all or part of the jackpot combination. Specifically, in the “left”, “middle”, and “right” effect symbol display areas 5L, 5C, and 5R (for example, “left” and “right” effect symbol display areas 5L and 5R, etc.) in advance. The remaining effect symbol display area (for example, “medium” effect) that has not been stopped yet when the effect symbol (for example, the effect symbol indicating the alphanumeric character of “7”) constituting the determined jackpot combination is stopped and displayed. In the symbol display area 5C, etc., the presentation symbols are changing, or in all or part of the “left”, “middle”, “right” effect symbol display areas 5L, 5C, 5R This is a display state that changes synchronously while constituting all or part of the combination.

  In response to the reach state, the rate of change of the effect symbol is reduced, or a character image (effect image imitating a person or the like) different from the effect symbol is displayed in the display area of the image display device 5. Or change the display mode of the background image, play and display a moving image that is different from the production symbol, or change the variation mode of the production symbol, so that the production operation different from before reaching the reach state is executed May be. Such an effect operation such as display of the character image, change of the display mode of the background image, reproduction display of the moving image, and change of the change mode of the effect pattern is referred to as reach effect display (or simply reach effect). In the reach effect, not only the display operation in the image display device 5 but also the sound output operation by the speakers 8L and 8R, the lighting operation (flashing operation) in the light emitter such as the effect LED 9 and the like before reaching the reach state. An operation mode different from the operation mode may be included.

  As an effect operation in the reach effect, a plurality of types of effect patterns (also referred to as “reach patterns”) having different operation modes (reach modes) may be prepared in advance. Each reach mode has a different possibility of “big hit” (also referred to as “reliability” or “big hit reliability”). That is, it is possible to vary the possibility that the variable display result will be a “big hit” depending on which of the multiple types of reach effects is executed.

  When a special symbol that becomes a lost symbol is stopped (derived) as a confirmed special symbol in the special symbol game, the variation display state of the production symbol does not reach the reach state after the variation display of the production symbol is started. In addition, a definite effect symbol that is a predetermined non-reach combination may be stopped and displayed. Such a variation display mode of the effect symbol is referred to as a “non-reach” (also referred to as “normal loss”) variable display mode when the variation display result is “losing”.

  When a special symbol that becomes a lost symbol is stopped (derived) as a confirmed special symbol in the special symbol game, the variation display state of the production symbol becomes the reach state after the variation display of the production symbol is started. Correspondingly, after the reach effect is executed, or when the reach effect is not executed, a confirmed effect symbol that becomes a predetermined reach lose combination may be stopped and displayed. Such a variation display result of the effect symbol is referred to as a variation display mode of “reach” (also referred to as “reach lose”) when the variation display result is “losing”.

  Corresponding to the fact that the variation display state of the production symbol has reached the reach state when the jackpot symbol indicating the number “3” is stopped and displayed as a special symbol that is a jackpot symbol as a special symbol to be confirmed in the special symbol game Then, after a predetermined reach effect is executed, a definite effect symbol that is a predetermined normal big hit combination (also referred to as “non-probable variable big hit combination”) among a plurality of types of big hit combinations is stopped and displayed. It should be noted that the non-probable big hit combination may be stopped and displayed as a confirmed effect symbol without the reach effect being executed.

  For example, the determined effect symbol that is a normal jackpot combination (non-probable variation jackpot combination) is variably displayed in the “left”, “middle”, and “right” effect symbol display areas 5L, 5C, and 5R in the image display device 5, for example. Among the effect symbols whose symbol numbers are “1” to “8”, any one of the effect symbols whose symbol numbers are even numbers “2”, “4”, “6”, “8” is “left”, What is necessary is just to be able to be stopped and displayed on a predetermined effective line in each of the “middle” and “right” effect symbol display areas 5L, 5C, and 5R. The effect symbols having the even number “2”, “4”, “6”, “8” constituting the normal jackpot combination are referred to as normal symbols (also referred to as “non-probable variation symbols”).

  Corresponding to the fact that the confirmed special symbol in the special figure game becomes the normal jackpot symbol, after the predetermined reach effect is executed, the finalized symbol of the normal jackpot combination (non-probable variable jackpot combination) is stopped and displayed. The variable display mode is referred to as a variable display mode (also referred to as “big hit type”) of “non-probable change” (also referred to as “normal big hit”) when the variable display result is “big hit”. It should be noted that the normal jackpot combination (non-probable variation jackpot combination) may be stopped and displayed as the confirmed effect symbol without executing the reach effect. Based on the fact that the fluctuation display result is “big hit” for the big hit type of “non-probable change”, the normal open big hit state is controlled, and after the end, time reduction control (time reduction control) is performed. By performing the time reduction control, the special symbol change display time (special figure change time) in the special figure game is shortened compared to the normal state. In the short-time control, so-called electric chew support is performed in which the winning frequency of the normal symbol is increased and the winning frequency of the normal variable winning ball device 6B is increased as described later. Here, the normal state is a normal game state that is different from a specific game state such as a big hit game state, and the initial setting state of the pachinko gaming machine 1 (for example, when a system reset is performed, after the power is turned on) The same control as in the state in which the initialization process is executed is performed. In the time-saving control, one of the conditions is established first, that is, a special game is executed a predetermined number of times (for example, 100 times) after the big hit gaming state ends, and the fluctuation display result is “big hit”. Sometimes it just needs to end.

  In the special symbol game, among the special symbols that become jackpot symbols, if the probability variation jackpot symbol such as the special symbol indicating the numbers “5” and “7” is stopped and displayed, the change display state of the effect symbol In response to the reach state being reached, after the reach effect similar to the case where the variation display mode of the effect symbol is “normal” is executed, among the multiple types of big hit combinations, a predetermined probability variation big hit combination and The determined effect design may be stopped and displayed. It should be noted that the probability variation big hit combination may be stopped and displayed as the confirmed effect symbol without the reach effect being executed. The confirmed effect symbol that is a probable big hit combination has, for example, a symbol number “1” variably displayed in each of the “left”, “middle”, and “right” effect symbol display areas 5L, 5C, and 5R in the image display device 5. Among the effect symbols “8” to “8”, effect symbols having the symbol number “5” or “7” are displayed in the effect symbol display areas 5L, 5C, and 5R of “left”, “middle”, and “right”. Any device that can be stopped and displayed on a predetermined effective line can be used. The effect symbols having the symbol numbers “5” and “7” constituting the probability variation jackpot combination are referred to as probability variation symbols. When the probability variation jackpot symbol is stopped and displayed as the confirmed special symbol in the special figure game, the confirmed effect symbol that is a normal jackpot combination may be stopped and displayed as a variation display result of the effect symbol.

  Regardless of whether the confirmed effect symbol is a normal jackpot combination or a promiscuous jackpot combination, the variation display mode in which the probability variation jackpot symbol is stopped and displayed as a confirmed special symbol in the special figure game will have a "big hit" variation display result. This is referred to as a variation display mode of “probability variation” (also referred to as “big hit type”). In this embodiment, among the big hit types of “probable change”, control is made to the normally open big hit state based on the fact that “5” and “7” change display results are “big hit” as the confirmed special symbols. Then, after the end, probability variation control (probability variation control) is performed together with the time reduction control.

  By performing the probability variation control, the probability that the fluctuation display result (special display result) becomes “big hit” in each special figure game is improved so as to be higher than that in the normal state. The probability variation control may be ended when the condition that the fluctuation display result is “big hit” and the game is controlled to the big hit gaming state again after the big hit gaming state is ended. Similar to the time reduction control, the probability variation control is ended when a predetermined number of times (for example, 100 times the same as the time reduction number or 90 times different from the time reduction number) are executed after the end of the big hit gaming state. May be. In addition, even if the probability variation control is ended when the probability variation control is ended by the probability variation control lottery executed every time the special game is started after the big hit gaming state is ended, the probability variation control is terminated. Good.

  When the time-shortening control is performed, the normal symbol display unit 20 controls the normal symbol in the normal symbol game so that the variation time of the normal symbol (ordinary symbol variation time) is shorter than that in the normal state. Control to improve the probability that the display result is “per normal figure” than in the normal state, and tilt control of the movable blade piece in the normal variable winning ball apparatus 6B based on the fact that the fluctuation display result is “per normal figure”. The game ball can easily pass (enter) the second start winning opening, such as a control to make the tilt control time for performing longer than that in the normal state, and a control to increase the number of tilts than in the normal state. Control (electricity support control) that is advantageous to the player by increasing the possibility that the start condition is satisfied is performed. In this way, the control that facilitates the entry of the game ball into the second start winning opening in accordance with the time-shortening control and is advantageous to the player is also referred to as high opening control. As the high opening control, any one of these controls may be performed, or a plurality of controls may be combined.

  By performing the high opening control, the frequency at which the second start winning opening becomes the expanded opening state is higher than when the high opening control is not performed. As a result, the second start condition for executing the special figure game using the second special figure in the second special symbol display 4B is easily established, and the special figure game can be executed frequently. The time until the fluctuation display result becomes “big hit” is shortened. The period during which the high opening control can be performed is also referred to as a high opening control period, and this period may be the same as the period during which the time reduction control is performed.

  The gaming state in which both the short time control and the high opening control are performed is also referred to as a short time state or a high base state. The gaming state in which the probability variation control is performed is also referred to as a probability variation state or a high probability state. A gaming state in which the time-shortening control or the high opening control is performed together with the probability variation control is also referred to as a high probability high base state. In this embodiment, the gaming state to be controlled is not set, but the probability variation state in which only the probability variation control is performed and the time-shortening control or the high opening control is not performed is also referred to as a high probability low base state. In addition, only the gaming state in which the time-shortening control or the high opening control is performed together with the probability variation control is sometimes referred to as a “probability variation state”, and may be referred to as a time variation probability variation state in order to distinguish from the high probability low base state. On the other hand, a probability variation state (high probability low base state) in which only time variation control is performed and time reduction control or high opening control is not performed is sometimes referred to as a time variation probability variation state in order to be distinguished from a high accuracy high base state. The short time state in which the short time control or the high opening control is performed without performing the probability variation control is also referred to as a low probability high base state. The normal state in which neither the probability variation control, the time reduction control, nor the high opening control is performed is also referred to as a low probability low base state. When at least one of time-shortening control and probability variation control is performed in a gaming state other than the normal state, the probability that the special-figure game can be executed frequently and the fluctuation display result in each special-figure game will be “big hit” As a result, the player is in an advantageous state. A gaming state advantageous to a player different from the big hit gaming state is also referred to as a special gaming state.

  When the small hit symbol is stopped and displayed, the game state is not changed after controlling to the small hit game state described above, and the game state before the change display result becomes “small hit” is displayed. Control may be continued.

  In addition to the effect control program, the ROM 121 mounted on the effect control board 12 shown in FIG. 2 stores various data tables used for controlling the effect operation. For example, the ROM 121 stores table data constituting a plurality of determination tables prepared for the effect control CPU 120 to make various determinations, determinations and settings, pattern data constituting various effect control patterns, and the like. Yes.

  As an example, the ROM 121 uses the effect control CPU 120 to control the effect operation by various effect devices (for example, the image display device 5 and the speakers 8L and 8R, the effect LED 9 and the decoration LED, the effect model, etc.). An effect control pattern table storing a plurality of types of effect control patterns to be stored is stored. The effect control pattern is composed of data indicating the control contents corresponding to various effect operations executed in accordance with the progress of the game in the pachinko gaming machine 1. The effect control pattern table only needs to store, for example, an effect control pattern during special figure change, a notice effect control pattern, and various effect control patterns.

  The special-control variation production control pattern corresponds to a plurality of types of variation patterns in the period from the start of the variation of the special symbol in the special-sign game until the finalized special symbol that is the special-sign display result is derived and displayed. It consists of data indicating the contents of control of various effect operations, such as effect display operations in effect symbol variation display operation, reach effect, re-lottery effect, etc., or various effect display operations not accompanied by effect symbol variation display Has been. The notice effect control pattern includes, for example, data indicating the control content of the effect operation that becomes the notice effect executed in response to the notice pattern in which a plurality of patterns are prepared in advance. The various effect control patterns are composed of data indicating the control contents corresponding to various effect operations executed in accordance with the progress of the game in the pachinko gaming machine 1.

  In the special-figure variation production control pattern, for example, a plurality of types of reach production control patterns with different production modes in each reach production may be included for each variation pattern that executes the reach production.

  In addition, examples of the notice effect that is executed during the change display of the effect symbol include, for example, a movable notice that the movable member is raised, and an operation notice that is executed on the condition that the player operates the stick controller 31A or the push button 31B. For example, a step-up notice that a predetermined image changes step by step, a line notice that a character appears and hits a line, a cut-in notice that a predetermined image is interrupted and displayed, Reach notice that suggests whether or not it will be, pseudo-continuous notice that informs whether or not it will become a pseudo-ream, stop-symbol notice that informs the stop symbol, whether or not the game state is a probability variation state (whether or not A plurality of notices executed at the start of variable display or when reach is established, such as a latent notice for notifying a person).

  Next, the structure and operation of the sub image display device 51 (sub liquid crystal) will be described. FIG. 3 is a side sectional view of the pachinko gaming machine 1. As shown in FIG. 3, the sub image display device 51 is provided on the back surface of the game board 2 and below the front surface side of the image display device 5. The sub-image display device 51 includes a moving unit 52 for moving the sub-image display device 51 up and down, and an inclined unit 54 that changes the inclination angle of the sub-image display device 51. The effect control CPU 120 mounted on the effect control board 12 changes the arrangement state of the sub-image display device 51 by controlling the moving unit 52 and the inclined unit 54 according to the effect state.

  At the initial position (standby position) indicated by the solid line in FIG. 3, the sub-image display device 51 is in a state where the display surface is inclined with respect to the image display device 5. Thus, at the initial position (standby position), the player can visually recognize a part of the sub-image display device 51 from the opening 2c. At that time, by tilting the sub-image display device 51 upward, it becomes nearly perpendicular to the player's line of sight, so that the display visibility of the sub-image display device 51 can be improved. In addition, in the initial position shown in FIG. 3, a part (upper part) of the sub-image display device 51 is superimposed on the image display device 5 when viewed from the front side. Good.

  The sub-image display device 51 can move to the superimposed position indicated by the solid line by moving horizontally (up and down) from the initial position indicated by the solid line by the operation of the moving unit 52. The effect control board 12 controls the moving unit 52 according to the effect state, and changes the sub-image display device 51 from the initial position to the superimposed position. In the superimposed position, the player can visually recognize the entire sub-image display device 51 through the opening 2c. Further, at the superimposition position, by driving the inclined portion 54, the sub-image display device 51 changes the inclination angle so as to be parallel to the game board 2, similarly to the image display device 5. As described above, even in the superimposition position, the display surface of the sub-image display device 51 is brought close to the player's line of sight so that the display visibility of the sub-image display device 51 is improved.

  The moving unit 52 and the inclined unit 54 are configured to include a driving source such as a motor, a gear, and the like. In the present embodiment, the effect control board 12 is connected via the relay board 53. The relay board 53 is provided with a relay function for a compressed video signal transmitted to the sub-image display device 51. The video signal that has passed through the relay substrate 53 is released from the compression state by the conversion substrate 511 and transmitted to the sub-image display device 51.

  In the cross-sectional view of the side surface of the pachinko gaming machine 1 in FIG. 3, the arrangement of various control components such as the main board 11 and the effect control board 12 and the state of the connection are shown. The main substrate 11 is disposed in the transparent box 11a. The transparent box 11a has a configuration provided to prevent unauthorized modification and the like, and is sealed so that it cannot be applied from the outside. In addition, although the cable for electrically connecting with external structures, such as the production | presentation control board 12, is connected to the main board | substrate 11, illustration in this figure is abbreviate | omitted.

  A cable 66 that outputs a video signal to the image display device 5 is connected to the effect control board 12 via a connector. In the present embodiment, an RGB signal is used as the form of the video signal output to the image display device 5. The effect control board 12 also outputs a video to the sub-image display device 51. In the present embodiment, the compressed video signal compressed by the display control unit 123 of the effect control board 12 is output. As a compression mode, video compression by V-by-One (registered trademark) is used. V-by-One is a compression method for compressing a video signal into a compressed video signal in a serial form. Since the signal compressed by V-by-One is a pair of differential signals, it can be routed by a cable composed of two impedance-controlled electric wires. Such a cable can be resistant to external noise by adopting a twisted pair configuration. Moreover, since such a cable does not require a strict shield, it can be a thin and flexible cable, and the degree of freedom of wiring in the pachinko gaming machine 1 can be improved. However, since V-by-One uses a high frequency range of 105 M to 840 Mbps (600 V to 3.65 Gbps for V-by-One HS), attention to external noise is required.

  The video compression signal output from the effect control board 12 is input to the relay board 53 via the cable 61, passes through the relay board 53, and is converted to the conversion board 511 disposed on the back surface of the sub-image display device 51 via the cable 64. Entered. The compressed video signal is decompressed by the conversion board 511 and converted into a video signal (RGB signal in this embodiment). The video signal is input to the sub-image display device 51 via the cable 65 and displayed. In the present embodiment, since the sub-image display device 51 is configured to move by the moving unit 52, a compressed video signal to be displayed on the sub-image display device 51 may be temporarily routed through the relay board 53. It is preferable for the convenience of wiring. Further, the relay substrate 53 of this embodiment is provided with driving means for driving the moving part 52 and the inclined part 54. The effect control board 12 outputs the control information DAT and the power supply POW to the driving means on the relay board 53 through the cable 61. The driving means of the relay board 53 outputs control signals to the moving unit 52 and the inclined unit 54 using the cables 62a and 62b.

  Next, the operation (action) of the pachinko gaming machine 1 in this embodiment will be described. In the main board 11, when power supply from a predetermined power supply board is started, the game control microcomputer 100 is activated, and the CPU 103 executes a predetermined process as a game control main process. When the game control main process is started, the CPU 103 performs necessary initial settings after setting the interrupt disabled. In this initial setting, for example, the RAM 102 is cleared. Also, register setting of a CTC (counter / timer circuit) built in the game control microcomputer 100 is performed. Thereby, thereafter, an interrupt request signal is sent from the CTC to the CPU 103 every predetermined time (for example, 2 milliseconds), and the CPU 103 can periodically execute timer interrupt processing. When the initial setting is completed, an interrupt is permitted and then loop processing is started. In the game control main process, a loop process may be entered after executing a process for returning the internal state of the pachinko gaming machine 1 to the state at the previous power supply stop.

  When the CPU 103 that has executed such a game control main process receives an interrupt request signal from the CTC and receives an interrupt request, it executes a game control timer interrupt process. When the game control timer interrupt process is started, the CPU 103 first executes a predetermined switch process, thereby causing the gate switch 21, the first start port switch 22A, the second start port switch 22B, and the count through the switch circuit 110. The state of the detection signal input from various switches such as the switch 23 is determined. Subsequently, by executing predetermined main-side error processing, abnormality diagnosis of the pachinko gaming machine 1 is performed, and a warning can be generated if necessary according to the diagnosis result. Thereafter, by executing a predetermined information output process, for example, data such as jackpot information, start information, probability variation information supplied to a hall management computer installed outside the pachinko gaming machine 1 is output.

  Subsequent to the information output process, a game random number update process for updating at least a part of game random numbers such as random number values MR1 to MR4 used on the main board 11 side by software is executed. Thereafter, the CPU 103 executes special symbol process processing. In the special symbol process, the value of the special symbol process flag provided in the game control flag setting unit (not shown) is updated according to the progress of the game in the pachinko gaming machine 1, and the first special symbol display 4A or 2 Various processes are selected and executed in order to perform control of display operation in the special symbol display 4B and setting of opening / closing operation of the special winning opening in the special variable winning ball apparatus 7 in a predetermined procedure.

  Following the special symbol process, the normal symbol process is executed. The CPU 103 executes the normal symbol process, thereby determining the normal symbol variation display mode using the random number MR4 for determining the normal symbol display result, and performing the display operation (for example, turning on the segment LED) on the normal symbol display 20. ), Etc., to control the normal symbol variation display, the tilting operation setting of the movable wing piece in the normal variable winning ball apparatus 6B, and the like.

  After executing the normal symbol process, the CPU 103 transmits a control command from the main board 11 to a sub-side control board such as the effect control board 12 by executing a command control process. As an example of these, in the command control process, the output port included in the I / O 105 corresponds to the setting in the command transmission table specified by the value of the transmission command buffer provided in the game control buffer setting unit. After setting the control data in the output port for transmitting the effect control command to the control board 12, the predetermined control data is set in the output port of the effect control INT signal and the effect control INT signal is turned on for a predetermined time. Then, by turning it off, etc., it is possible to transmit the effect control command based on the setting in the command transmission table. After executing the command control process, after setting the interrupt enabled state, the game control timer interrupt process is terminated.

  In the special symbol process, the CPU 103 first executes a start winning determination process. After executing the start winning determination process, the CPU 103 selects and executes one of processes according to the value of the special figure process flag provided in the game control flag setting unit.

  In the start winning process, it is determined whether or not there is a first start prize or a second start prize by the first start port switch 22A or the second start port switch 22B. Random number value MR1, jackpot type determination random value MR2 and fluctuation pattern determination random value MR3 are extracted, and in the case of the first starting prize, the highest number of empty entries in the first special figure reservation storage unit In the case of the second start winning prize, it is stored at the top of the empty entry in the second special figure reservation storage unit.

  In the special symbol normal process, the first special symbol indicator 4A and the second special symbol indicator 4B are based on the presence / absence of reserved data stored in the first special symbol storage unit and the second special symbol storage unit. It is determined whether or not to start the special game. In the special symbol normal process, whether the variation display result of the special symbol or the effect symbol is “big hit” based on the numerical data indicating the random value MR1 for determining the special symbol display result, Make a decision (predetermined) before being displayed. Further, in the special symbol normal process, in response to the special symbol variation display result in the special symbol game, the confirmed special symbol (the jackpot symbol or the like in the special symbol game by the first special symbol indicator 4A or the second special symbol indicator 4B). One of the lost symbols) is set.

  In the variation pattern setting process, a variation pattern is selected from a plurality of variations using numerical data indicating a variation pattern determination random value MR3 based on a result of prior determination as to whether or not the variation display result is “big hit”. The process to decide on is included.

  By the special symbol normal process and the variation pattern setting process, the variation pattern including the variation display time of the confirmed special symbol, the special symbol, and the effect symbol which are the variation display result of the special symbol is determined. That is, the special symbol normal processing and the variation pattern setting processing are performed using the special symbol display result determination random number MR1, the jackpot type determination random value MR2, and the variation pattern determination random value MR3. The process which determines the fluctuation | variation display mode of is included.

  In the special symbol variation process, the first special symbol display unit 4A and the second special symbol display unit 4B perform a setting process for varying the special symbol, and the elapsed time after the special symbol starts variation. Processing to measure is included. In the special symbol stop process, the first special symbol display unit 4A or the second special symbol display unit 4B stops the variation of the special symbol, and the definite special symbol which is the variation display result of the special symbol is stopped and displayed (derived). ) Includes a process for performing setting. Then, it is determined whether or not the big hit flag provided in the game control flag setting unit is on.

  The process for pre-opening the big hit includes processing to start the round in the big win gaming state and set the big winning opening to the open state based on the fact that the fluctuation display result is “big hit”, etc. It is. In the big hit opening process, the winning prize opening is determined based on the process of measuring the elapsed time since the big winning opening is in the open state, the measured elapsed time, the number of game balls detected by the count switch 23, and the like. A process for determining whether or not it is time to return from the open state to the closed state is included. After the big hit opening process, the process of determining whether or not the number of executions of the round that sets the grand prize opening state has reached the maximum number of opening of the big winning opening, or when the maximum number of opening of the big winning opening has been reached Includes processing for making a setting for transmitting a jackpot end designation command. In the jackpot end process, there is a waiting time corresponding to a period in which an ending effect as an effect operation for informing the end of the jackpot gaming state is performed by an effect device such as the image display device 5, the speakers 8L and 8R, the effect LED 9 or the like. This includes a process of waiting until it elapses, and a process of performing various settings (setting of a probability change flag and a time reduction flag) for starting the probability change control and the time reduction control in response to the end of the big hit gaming state.

  In the big hit ending process, the big hit type buffer value stored in the game control buffer setting unit (not shown) is read to identify whether the big hit type is “non-probable variable big hit” or “probable big hit”. . If it is determined that the identified big hit type is not “non-probable variation big hit”, setting for starting the probability variation control (setting of the probability variation flag) is performed. In addition, when the specified big hit type is “non-probable variable big hit”, the setting for starting the time reduction control (in advance corresponding to the setting of the time reduction flag and the upper limit value of the special game that can be executed during the time reduction control). A predetermined count initial value (“100” in the present embodiment) is set in the short-time counter.

  Next, the operation of the effect control board 12 will be described. First, the effect control CPU 120 starts executing the main process when the power is turned on. In the main processing, first, initialization processing is performed for clearing the RAM area, setting various initial values, and initializing a timer for determining an activation control activation interval (for example, 2 ms). Thereafter, the effect control CPU 120 shifts to a loop process for monitoring the timer interrupt flag. When the timer interrupt occurs, the effect control CPU 120 sets a timer interrupt flag in the timer interrupt process. If the timer interrupt flag is set (turned on) in the main process, the effect control CPU 120 clears the flag and executes the following process.

  The effect control CPU 120 first analyzes the received effect control command and performs a process of setting a flag according to the received effect control command (command analysis process). In this command analysis process, the effect control CPU 120 confirms the content of the command transmitted from the main board 11 stored in the reception command buffer. The effect control command transmitted from the game control microcomputer 100 is received by an interrupt process based on the effect control INT signal and stored in a buffer area formed in the RAM. In the command analysis process, which command is the effect control command stored in the buffer area is analyzed.

  Next, the effect control CPU 120 performs effect control process processing. In the effect control process, the process corresponding to the current control state (effect control process flag) is selected from the processes corresponding to the control state, and display control of the image display device 5 is executed.

  Next, an effect random number update process for updating the count value of a counter for generating an effect random number such as a jackpot symbol determination random number is executed, and then the process proceeds to a timer interrupt flag monitoring process.

  FIG. 4 is a block diagram showing various configurations around the relay board 53. As described in FIG. 2, the effect control board 12 is provided with the effect control CPU 120 and the display control unit 123. The display control unit 123 includes a VDP 123a (Video Display Processor) and a converter 123b. Based on the command from the effect control CPU 120, the VDP 123 a uses the image information stored in the ROM 121 and the RAM 122, and uses the video signal for the image display device 5 and the video signal (RGB signal) for the sub-image display device 51. ). The video signal for the image display device 5 is output to the image display device 5 via the cable 66 and displayed. On the other hand, the video signal for the sub-image display device 51 is subjected to video compression by V-by-One in the converter 123b and converted into a compressed video signal. The compressed video signal for the sub-image display device 51 is input to the conversion board 511 via the signal line 534 of the relay board 53. The conversion board 511 converts the compressed video signal in the V-by-One format into a video signal (RGB signal). The compressed video signal is input to the sub-image display device 51 via the cable 65 and displayed.

  As described above, the relay substrate 53 is provided with driving means for driving the moving part 52 and the inclined part 54. The drive means includes a serial parallel IC 531 and motor drive units 532 and 533. The serial parallel IC 531 receives the serial control information DAT output from the effect control board 12 via the cable 61. The serial parallel IC 531 converts the control information DAT in the serial form into a parallel form, and distributes and outputs it to the motor drive units 532 and 533. The motor drive units 532 and 533 drive and control the moving unit 52 and the inclined unit 54 using the distributed control information DAT. The serial parallel IC may be configured to output the control information DAT input in this way without distributing the control information DAT to the moving unit 52 and the inclined unit 54. In this case, address information addressed to the motor drive unit 532 and the motor drive unit 533 is assigned to the control information DAT, and the motor drive units 532 and 533 extract the control information DAT to which address information addressed to itself is assigned. use. Although not shown, a clock signal for synchronization is input to the serial parallel IC in addition to the control information DAT. Further, the power POW is supplied to the serial parallel IC 531 and the motor driving units 532 and 533 using the cable 61. The cable 61 is configured by bundling a signal line for transmitting control information DAT and a power line for transmitting power POW.

  The motor drive unit 532 outputs a drive signal for driving the first motor 521 serving as a drive source for the moving unit 52 based on the control information DAT received from the serial parallel IC 531 and the supplied power POW. In addition, the motor drive unit 533 outputs a drive signal for driving the first motor 521 serving as a drive source of the tilting unit 54 based on the control information DAT received from the serial parallel IC 531 and the supplied power POW.

  As described above, the relay board 53 of the present embodiment is provided with driving means for driving the moving portion 52 and the inclined portion 54 such as the signal line 534 for transmitting the compressed video signal and the motor driving portions 532 and 533. Since both the compressed video signal and the driving means are signals and configurations related to the sub-image display device 51, handling by one relay board 53 in this way shortens the wiring and simplifies wiring. It is possible to improve the degree of freedom. The compressed video signal passing through the signal line 534 is a high-band differential signal due to compression by V-by-One. When passing through a twisted pair cable in which two electric wires are twisted, although having resistance against external noise, when passing through the signal line 534 on the relay substrate 53, attention to external noise is required. In the present embodiment, the signal line 534 that requires attention to external noise, such as the high-bandwidth compressed video signal, has a feature in the configuration within the laminated substrate.

  The relay substrate 53 of this embodiment is configured by a six-layer laminated substrate. FIG. 5 is a schematic view showing a cross section of the relay substrate 53. This figure is a diagram schematically showing the cables 61 to 64 connected to the relay board 53 and the state of signals in each layer. It is different.

  The first layer (first wiring layer) is a layer that forms one surface of the relay substrate 53, and connectors 536 to 540 are provided on the exposed surface. Connectors 536 to 540 are connected to a connector (not shown) on the cable 61 side, and are electrically connected to each component. In addition, on the exposed surface of the first layer, wiring (not shown) for leading various signal paths led out from the connectors 536 to 540 to necessary positions is provided. This wiring is formed as a wiring pattern formed by etching or the like.

  The second layer (one ground layer) and the fourth layer (second ground layer) are provided to protect the signal line 534 from external noise. The second layer and the fourth layer are configured to have electrodes (solid pattern) having a large area. These electrodes are electrically connected to a ground line included in the cable 61 or the like, and form the first ground line of this embodiment.

  The third layer (second wiring layer) is a layer in which the signal line 534 is provided. In this embodiment, it is sandwiched between the first ground line of the second layer and the second ground line of the fourth layer, so that even the planar signal line 534 is resistant to external noise. Yes. The compressed video signal input from the cable 63 is input to the relay board 53 via the connector 537. In the relay board 53, the compressed video signal passes through the first ground line of the second layer and the signal line 534 whose both surfaces are protected by the second ground line of the third layer, and is connected to the cable via the connector 538. 64 to the conversion board 511. Since the cables 63 and 64 have a twisted pair configuration and the compressed video signal is a differential signal, the compressed video signal has high durability against external noise when passing through the cables 63 and 64. However, when passing through the signal line 534 formed flat in the relay substrate 53, the compressed video signal is easily affected by external noise. Thus, the ground lines provided in the second layer and the fourth layer are provided in order to suppress the influence of external noise in the signal line 534 of the relay board 53. In the present embodiment, the ground layer is also provided around the signal line 534 in the third layer, thereby further suppressing the influence of external noise on the compressed video signal.

  The fourth layer (power supply layer) has a power supply line 535 for supplying power to the serial parallel IC 531 and the motor drive units 532 and 533. The power POW input from the connector 536 passes through the power line 535 formed in the fourth layer, and is supplied to the serial parallel IC 531 and the motor driving units 532 and 533 provided in the sixth layer. In the power supply line 535 of this embodiment, a compressed video signal is input / output with the second layer (first ground layer), the third layer (second wiring layer), and the fourth layer (second ground layer) interposed therebetween. It is arranged on a different side from the connectors 537 and 538. It is conceivable that the power supply POW passing through the power supply line 535 fluctuates (swings) due to fluctuations in the power supplied to the pachinko gaming machine 1 or the like. The fluctuation of the power supply POW becomes the external noise of the compressed video signal passing through the signal line 534. However, since the signal line 534 is shielded (shielded) by the fourth layer (second ground layer) in particular, the power supply POW Even when fluctuation occurs, it is possible to suppress the influence on the compressed video signal passing through the signal line 534.

  The fifth layer (third wiring layer) is a layer that forms the other surface of the relay substrate 53, and a serial parallel IC 531 and motor driving units 532 and 533 constituting driving means are arranged on the surface. . The control information DAT input from the connector 536 is sent to the serial parallel IC 531 via the wiring provided in the first layer (first wiring layer) or the wiring provided in the sixth layer (third wiring layer). Entered. The control information DAT converted into the parallel form by the serial parallel IC 531 is input to the motor drive units 532 and 533 and converted into drive signals. The drive signal output from the motor drive unit 532 is output to the first motor 521 of the moving unit 52 via the connector 539 and the cable 62a. The drive signal output from the motor drive unit 533 is output to the second motor 541 of the inclined unit 54 via the connector 540 and the cable 62b.

  Since the serial parallel IC 531, the motor drive unit 532, and the control information DAT handled by the motor drive unit 533 and the drive signal are temporally fluctuating signals, it may be an external noise of the compressed video signal. In particular, since the drive signals for driving the first motor 521 and the second motor 541 are signals having a large current value, the influence on the compressed video signal is expected to be large. In the present embodiment, a processing unit (serial parallel IC 531, motor driving units 532, 533) that processes a signal (control information DAT, drive signal) different from the compressed video signal is input / output on the relay board 53. The connectors 537 and 538 are arranged on a different side. By adopting such an arrangement, when the serial parallel IC 531 and the motor drive units 532 and 533 process the signal, the generated external noise affects the compressed video signal passing through the connectors 537 and 538 and the cables 63 and 64. It is possible to suppress this. In particular, since the second layer (first ground layer) and the fourth layer (second ground layer) are shielded (shielded), the suppression effect can be greatly expected.

  Next, the configuration of each layer of the relay substrate 53 will be described with reference to FIGS. 6A and 6B are diagrams showing the configuration of the first layer (first wiring layer) of the relay substrate 53. FIG. 6A is a front view of the first layer, and FIG. 6B is the first layer. The side view of is shown. As described with reference to FIG. 5, connectors 536 to 540 are provided in the first layer. The connectors 536 to 540 are means for connecting the cables 61 to 64, and are electrically connected to various configurations by connecting to a connector (not shown) provided on the cables 61 to 64 side. As for the connectors connected to the cables 61 to 64, a side type that extends the cable in the left-right direction in the drawing, and a top type that produces the cable in the upward direction in the drawing are used depending on the arrangement form. . In the example of FIG. 6, the side type is used for the connectors of the cables 61 and 63, and the top type is used for the connectors of the cables 62a, 62b, and 64.

  As the connectors 536 to 540, connectors 536 and 537 having pin electrodes and connectors 538, 539 and 540 having no pin electrodes are used according to the size, the cable to be used, and the like. The connectors 536 to 540 are fixed to the corresponding connector electrodes 536a to 540a by soldering. The connector electrodes 536a and 537a of the connectors 536 and 537 having pin electrodes are through holes that penetrate the relay board 53 and the surroundings thereof. Electrode. By passing the pin electrodes of the connectors 536 and 537 through the through holes and soldering, the connectors 536 and 537 can be firmly fixed on the relay substrate 53. On the other hand, the connectors 538, 539, and 540 having no pin electrode are fixed to the connector electrodes 538a, 539a, and 540a formed exposed on the surface of the first layer by soldering. Further, the connectors 538, 539, and 540 having no pin electrode are provided with relatively small through holes in order to conduct to other layers. The electrode formed on the inner wall of the through hole is electrically connected to the wiring of the other layer. A connector having a pin electrode and a connector having no pin electrode can be appropriately determined according to the connector to be used and the cable. In this embodiment, as can be seen from FIGS. 6 to 11, the through holes of the connector electrodes 536 a to 540 a are provided through all the layers of the relay substrate 53. This is to facilitate the manufacture of the relay board 53. For example, the connector electrodes 537a and 538a need only penetrate through the first layer and the second layer, but can be easily manufactured by forming through all the layers. The connector electrodes 537a and 538a can be formed so as to penetrate only the first layer and the second layer, thereby improving the shielding performance. In addition to the connector electrodes 536a to 540a shown in FIGS. 6 to 11, the relay substrate 53 is provided with a plurality of through holes for conducting the electrodes between different layers. However, these through holes are not shown. ing.

  FIG. 7 is a front view of the second layer (first ground layer) of the relay substrate 53. In the second layer, a first ground line indicated by diagonal lines is arranged. The first ground line in the second layer is formed of an electrode (solid substrate) having an area that occupies substantially the entire area in the second layer, as indicated by hatching. The first ground line is electrically connected to one upper right electrode of the connector electrode 536a to which the ground line is connected. Therefore, the entire first ground line has the same potential as the ground line. The fourth layer (second ground layer) shown in FIG. 9 is the same, and a second ground line indicated by diagonal lines is formed. The first ground line and the second ground line are preferably connected to the ground line at a plurality of locations. For example, when the current consumption in the first motors 521 and 541 is large, a plurality of ground wires are connected to the connector electrodes 539a and 540a to which the motor driving units 532 and 533 are electrically connected in order to ensure grounding. ing. The first ground line and the second ground line may be electrically connected to a plurality of ground lines using not only the connector electrode 536a but also the connector electrodes 539a and 540a. It becomes possible to more reliably ground the first ground line and the second ground line. In addition, the first ground line and the second ground line are regions in which the ground line is not provided in the second layer and the fourth layer in addition to forming so as to occupy substantially the entire area of the second layer and the fourth layer. The form which has this may be sufficient. In such a configuration, it is possible to use a region where the ground line is not provided in the second layer and the fourth layer for wiring or the like.

  8A is a front view of the third layer (second wiring layer) of the relay board 53, and FIG. 8B is a cross-sectional view of the relay board 53 taken along line AB in FIG. 8A. (Second to fourth layer portions). In the third layer, the connector electrode 537a and the connector electrode 538a are electrically connected by a signal line 534 including two unit signal lines 534u. A differential compressed video signal is transmitted using the two unit signal lines 534u. Since the upper layer (second layer) and the lower layer (fourth layer) occupied by the two unit signal lines 534u are shielded (shielded) by the ground line, the compressed video signal passing through the signal line 534 is external. The configuration is less susceptible to noise. Further, in the present embodiment, the periphery of the connector electrodes 537a and 538a and the two unit signal lines 534u is surrounded by a ground line indicated by hatching, so that the configuration is less susceptible to external noise. The ground line of the third layer is electrically connected to the upper right one electrode to which the ground line is connected, as in the second and fourth layers. In the present embodiment, the ground line of the third layer is provided over substantially the entire area of the third layer. However, in the third layer, an area where the ground line is not provided is left, and the area other than the signal line 534 is connected. It is good also as using for.

  FIG. 8B shows a state where the signal line 534 is electromagnetically shielded (shielded) between A and B shown in FIG. The unit signal line 534u constituting the signal line 534 is electromagnetically shielded (shielded) by an upper layer (second layer) ground line and a lower layer (fourth layer) ground line. The gap X from the side surface of the unit signal line 534u to the ground layer of the third layer is the same distance in the entire signal line 534. The gap X is determined so that the signal line 534 has a predetermined resistance value in the use band of the compressed video signal. The parameters used for determining the gap X include the use band of the compressed video signal, the width a of the unit signal line 534u, the interval b, the thickness c, the material constituting the unit signal line 534u, and, in this embodiment, the upper layer. Since the ground lines are provided in the (second layer) and the lower layer (fourth layer), the distance d from the third layer ground line to the second layer (fourth layer) ground line is used. . Based on these parameters, the optimum gap X is determined by simulating on a computer.

  FIG. 10 is a front view of the fifth layer (power supply layer) in the relay substrate 53. In the relay board 53, a black line is a power line 535. The power supply line 535 supplies the power POW supplied from the connector electrode 536a to the serial parallel IC 531 and the motor driving units 532 and 533.

  FIG. 11 is a front view of the sixth layer (third wiring layer) in the relay substrate 53. In the sixth layer, serial parallel IC 531, motor drive ICs 532 a to 532 d constituting motor drive unit 532, and motor drive ICs 533 a to 533 d constituting motor drive unit 533 are arranged. These components are arranged on the exposed surface (back surface) of the relay substrate 53 as shown in FIG. Therefore, in FIG. 11, the serial parallel IC 531, the motor drive ICs 532 a to 532 d constituting the motor drive unit 532, and the motor drive ICs 533 a to 533 d constituting the motor drive unit 533 are arranged when viewed through the sixth layer. ing. The sixth layer is provided with wiring by electrodes that electrically connect the respective components, but is not shown here.

  As described above, the relay substrate 53 of the present embodiment is formed of a multilayer substrate, and at least a part of the region where the signal line 534 through which a predetermined signal (compressed video signal) passes is provided in the second layer. In addition, since it is sandwiched between the first ground line and the second ground line provided on the fourth layer, the configuration is improved in resistance to external noise.

  Further, the relay board 53 of the present embodiment has connectors 537 and 538 to which predetermined signals are input and output with the fifth layer (power supply layer) on which the power supply line 535 is disposed sandwiching the second to fourth layers. By arranging them on the side different from the surface (first layer) on which is placed, the ground lines of the second layer and the fourth layer act as electromagnetic shields (shields), and the power supply POW fluctuates. Even if it occurs, it is possible to suppress the influence on the compressed video signal.

  Furthermore, the relay board 53 of the present embodiment has a ground line surrounding the signal line 534 in the third layer (second wiring layer), thereby improving the electromagnetic shielding performance with respect to the signal line 534. Is possible.

  Further, in the relay board 53 of this embodiment, the gap between the signal line 534 and the ground line of the third layer (second wiring layer) is the same as that of the ground line of the third layer (second wiring layer) and the second layer (second wiring layer). The distance d between the ground lines of the first ground layer) and the distance d between the ground line of the third layer (second wiring layer) and the ground line of the fourth layer (second ground layer) are set. Considering the distance between the upper and lower layers (second layer and fourth layer) with respect to the third layer in which the signal line 534 is disposed, the signal line 534 has a suitable impedance characteristic, and reflection within the signal line is reduced. In addition, it is possible to improve signal quality and noise resistance.

  Further, the predetermined signal (compressed video signal) of the present embodiment is a serial video signal. When the video signal is in the serial form, the use band becomes high due to the large amount of information (V-by-One is 105 M to 840 Mbps, V-by-One HS is 600 M to 3.65 Gbps). . A signal having such a high frequency is easily affected by external noise, but by adopting the configuration of the relay substrate 53 of the present embodiment, improvement in resistance to external noise can be expected.

  Further, the predetermined signal (compressed video signal) of the present embodiment is a differential video signal. When the video signal is in a differential form, it is possible to improve resistance to external noise by using a twisted pair form cable for transmission. In addition, a twisted pair cable does not require a strict shield for noise countermeasures, so a supplementary flexible cable can be used, and the flexibility of wiring in the pachinko gaming machine 1 can be improved. It becomes.

  In the previous embodiment described with reference to FIG. 5 and the like, the signal line 534 in the third layer (second wiring layer) is allowed to pass through the relay substrate 53.

At that time, the processing for the compressed video signal is provided with a surface different from the surface on which the driving means is disposed, such as the serial parallel IC 531 and the motor driving unit 532, that is, connectors 537 and 538 for inputting and outputting the compressed video signal. It is preferable to carry out in terms of surface. By performing processing on the compressed video signal on a surface different from the surface on which the driving unit is arranged on the relay substrate 53, it is possible to suppress external noise generated by the driving unit from affecting the compressed video signal. . In particular, in this embodiment, since the ground line acts as an electromagnetic shield for external noise generated by the driving means in the second layer (first ground layer) and the third layer (fourth ground layer), compression is performed. Improving the tolerance of the video signal against external noise.

  FIG. 12 is a schematic diagram showing a cross section of the relay board 53 that performs various processes on the compressed video signal. Since the arrival of the signal relating to the driving means constituted by the serial parallel IC 531 and the motor driving units 532 and 533 is the same as in FIG. 5, the description thereof is omitted here. The present embodiment is different in that a video IC is provided on a surface different from the driving unit on the relay substrate 53.

The converter 123b performs compression by V-by-One and converts the four video signals into one compressed video signal. This compressed video signal is a serial-type differential signal. Since the compressed video signal is a signal obtained by compressing four video signals, it is expected that the amount of information becomes large, the use band becomes high, and it is easily affected by external noise. Since the signal line 534 provided on the relay board 53 has the excellent shielding performance described with reference to FIG. 5 and the like, it can be resistant to external noise even when a compressed video signal having a high use band passes.
