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.

  A normal symbol display 20 is provided above the second holding display 25B. As an example, the normal symbol display 20 is composed of 7 segments, dot matrix LEDs, and the like, like the first special symbol display 4A and the second special symbol display 4B, and a plurality of types of identification information different from the special symbols. Is displayed (variable display) so that it can be variably displayed. Such a normal symbol variation display is referred to as a general game (also referred to as a “normal game”).

  Above the normal symbol display 20, a universal figure holding display 25 </ b> C is provided. The general-purpose hold indicator 25C includes, for example, four LEDs, and displays the general-purpose hold storage number as the number of effective passing balls that have passed through the passing gate 41.

A trigger sensor that detects a predetermined instruction operation such as a push / pull operation on the trigger button may be built in the operation rod.

  A controller sensor unit 35 </ b> A for detecting a tilting operation with respect to the operating rod may be provided in the lower pan body inside the stick controller 31 </ b> A. For example, the controller sensor unit includes two transmissive photosensors (parallel sensors) arranged in parallel to the board surface of the game board 2 on the left side of the center position of the operating rod when viewed from the player side facing the pachinko gaming machine 1. And a pair of transmission type photosensors (vertical sensor pairs) arranged perpendicularly to the surface of the game board 2 on the right side of the center position of the operation rod when viewed from the player side. What is necessary is just to be comprised including a shape photosensor.

  The member that forms the upper plate includes, for example, a push button 31B that allows a player to perform a predetermined instruction operation by a pressing operation or the like at a predetermined position on the front side of the upper surface of the upper plate body (for example, above the stick controller 31A). Is provided. The push button 31B only needs to be configured to be able to detect the pressing operation from the player mechanically, electrically, or electromagnetically. A push sensor 35B that detects a pressing operation performed by the player on the push button 31B may be provided inside the main body of the upper plate at the position where the push button 31B is installed.

  Next, the progress of the game in the pachinko gaming machine 1 will be schematically described. In the pachinko gaming machine 1, the normal symbol display 20 executes the normal symbol variation display such that the game ball that has passed through the passing gate 41 provided in the gaming area 10 is detected by the gate switch 21 shown in FIG. 2. The normal symbol indicator is displayed on the basis of the fact that the normal symbol start condition for starting the normal symbol variation display is satisfied, for example, that the previous general symbol game has been completed The usual game by 20 is started.

  In this ordinary game, after a normal symbol change is started, when a predetermined time which is a normal symbol change time elapses, a fixed normal symbol which is a normal symbol change display result is stopped and displayed (derived display). 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 effect 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 variation design”) that has not been stopped yet when the effect design that is stopped and displayed in the display area of the effect display device 5 forms 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 variation speed of the effect symbol is reduced, or a character image (effect image imitating a person) different from the effect symbol is displayed in the display area of the effect 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 effect 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 game effect lamp 9, and the like are in the reach state. An operation mode different from the previous 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.

  The confirmed effect symbol which is a normal big hit combination (non-probable variation big hit combination) is variably displayed in, for example, the “left”, “middle” and “right” effect symbol display areas 5L, 5C and 5R in the effect display device 5. Among the effect symbols having the symbol numbers “1” to “8”, any one of the effect symbols having the even symbol 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 effect display areas 5L, 5C, and 5R of “middle” and “right”. 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 is, for example, a symbol number “1” that is variably displayed in each of the effect symbol display areas 5L, 5C, and 5R of the “left”, “middle”, and “right” in the effect display device 5. Among the effect symbols of “8”, the effect symbol whose symbol number is “7” is a predetermined effective line in the effect symbol display areas 5L, 5C, 5R of “left”, “middle”, and “right”. What is necessary is just to be able to be stopped and displayed all together. The effect symbol having the symbol number “7” constituting the probability variation jackpot combination is referred to as a probability variation symbol. 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.

The control command transmitted from the main board 11 to the effect control board 12 via the relay board 15 is, for example, an effect control command transmitted and received as an electric signal. In the effect control command, for example, a change pattern designation command indicating a change pattern indicating a change pattern such as a change time of an effect symbol, a type of reach effect, and the presence or absence of a pseudo-continuous, and an image display operation in the effect display device 5 are controlled. Display control commands used for the purpose, voice control commands used for controlling the sound output from the speakers 8L, 8R, lamp control commands used for controlling the lighting operation of the game effect lamp 9 and the decoration LED, etc. It is included.

  The game control microcomputer 100 mounted on the main board 11 is, for example, a one-chip microcomputer, and includes a ROM (Read Only Memory) 101 for storing a game control program, fixed data, and the like, and a game control work area. A RAM (RandomAccessMemory) 102 to be provided; a CPU (Central Processing Unit) 103 that executes a control program by executing a game control program; a random number circuit 104 that updates numeric data indicating a random number value independently of the CPU 103; And an I / O (Input / Output port) 105.

  As an example, in the game control microcomputer 100, a process for controlling the progress of the game in the pachinko gaming machine 1 is executed by the CPU 103 executing a program read from the ROM 101. At this time, the CPU 103 reads out fixed data from the ROM 101, the CPU 103 writes various fluctuation data in the RAM 102, temporarily stores the fluctuation data, and the CPU 103 temporarily stores various fluctuation data in the RAM 102. The CPU 103 receives the input of various signals from outside the game control microcomputer 100 via the I / O 105, and the CPU 103 goes outside the game control microcomputer 100 via the I / O 105. A transmission operation for outputting various signals is also performed.

  As shown in FIG. 2, the effect control board 12 is provided with an effect control CPU 120 that performs a control operation according to a program, a ROM 121 that stores an effect control program, fixed data, and the like, and a work area for the effect control CPU 120.

  Further, in the present embodiment, the effect display device 5 is disposed on the back side of the game board 2 and can be visually recognized through the opening 2c formed in the game board 2. Note that a frame-shaped center decorative frame 51 is provided in the opening 2 c in the game board 2. An effect unit (not shown), which will be described later, is provided between the back of the game board 2 and the effect display device 5, and various motors provided in the effect unit (not shown) are provided on the effect control board 12. A plurality of electronic components such as a solenoid, a sensor, and a light emitting diode (LED) are connected.

  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, the process for returning the internal state of the pachinko gaming machine 1 to the state at the time of the previous power supply stop may be executed before entering the loop process.

  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 becomes 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 is reached Includes processing for making a setting for transmitting a jackpot end designation command. In the big hit end process, a waiting time corresponding to a period in which an ending effect as an effect operation for notifying the end of the big hit gaming state is executed by an effect device such as the effect display device 5, the speakers 8L and 8R, the game effect lamp 9 or the like. And a process for 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.

  Furthermore, since the groove 273 is formed in a size that allows the protrusions 263 and 263 to be loosely fitted, that is, a size that fits in a state having play (a size that can be accommodated in a non-contact state), During welding, which will be described later, the inner surface of the groove 273 and the outer surface of the protrusions 263, 263 are not in contact with each other.

  On the cover side welding surface 271a, an outer welding protrusion 274 formed in a substantially rectangular frame shape protrudes, and on the inner side, an inner welding protrusion 275 formed in a substantially circular frame shape protrudes. ing. The outer welding ridges 274 and the inner welding ridges 275 have their centers arranged at the same position, and are each divided into two on a virtual straight line passing through the center in the left-right direction. That is, on the imaginary straight line passing through the center of each of the outer welding ridges 274 and the inner welding ridges 275, the air in the inner region surrounded by the outer welding ridges 274 during the welding is outside the inner region. Relief passages 276 and 277 are formed for escape.

  The escape passages 276 and 277 have a predetermined width, and are formed at two locations on each of the outer welding projection 274 and the inner welding projection 275. Since these are all arranged on a virtual straight line passing through the center and pointing in the left-right direction, the outer welding protrusion 274 and the inner welding protrusion 275 are line-symmetric with respect to the virtual straight line passing through the center in the left-right direction. Has been placed. Moreover, the outer side welding protrusion 274 and the inner side welding protrusion 275 are formed in the longitudinal cross-section substantially triangular shape tapering toward the base side welding surface 261a (illustration omitted), and the top part contact | abuts to the base side welding surface 261a. It is like that.

  The cover-side weld portion 223 formed in this way is connected to support plates 270a and 270b extending to the left side from the left side wall 202d of the cover member 202 via the connection portions 280a and 280b. Is provided. Specifically, the welding plate portion 271 is viewed from the front with respect to a guide piece 282 having a substantially U-shaped front view formed at a position corresponding to the welding plate portion 271 on the inner wall of the left side wall 202d and the support plates 270a and 270b. The substantially U-shaped gap S <b> 1 (a region surrounded by diagonal lines in FIG. 7A) is disposed.

  The connecting portion 280a connects the support plate 270a and the welding plate portion 271 and the connecting portion 280b connects the support plate 270b and the welding plate portion 271. These connecting portions 280a and 280b are extended in a direction orthogonal to the sliding movement direction of the cover member 202 with respect to the base member 201. Further, each of the connecting portions 280a and 280b is formed in a plate shape as shown in FIG. 7, and a gap S1 is formed in the periphery thereof, so that it can be cut by a tool such as a cutter, nipper, or yarn saw. ing.

  A connecting wall 284 protrudes forward from the right side of the welding plate portion 271. Further, a connecting wall 285 protruding from the front surface of the guide piece 282 is provided at a position facing the connecting wall 284 across the gap S1. The connecting wall 284 and the connecting wall 285 are connected by a connecting tube portion 286 having a cylindrical portion, and the insertion piece 264 of the base member 201 is inserted at a position corresponding to the connecting tube portion 286 in the connecting wall 285. A possible opening 287 is formed. In addition, the right side of the connection cylinder part 286 is open | released to the front side, and the front-end | tip of the insertion piece 264 inserted in the opening 287 can be visually recognized now.

  That is, the welding plate portion 271 having the cover-side welding portion 223 has three connection portions of the connection portions 280a and 280b and the connection cylinder portion 286 with respect to the body of the cover member 202 such as the support plates 270a and 270b and the left side wall 202d. Are connected through.

  Next, a sealing state between the base member 201 and the cover member 202 will be described. First, as shown in FIG. 3, the main board 11 is attached to the front surface (back surface) side of the cover member 202 via the mounting screws 238. At this time, with the mounting surface 11a of the main board 11 facing the front surface of the cover member 202, the main board 11 is fitted and positioned in the cover member 202, and mounting screws 238 are attached to the four corners of the main board 11. The cover member 202 is attached to a screw hole (not shown).

  In this way, even when the cover member 202 is illegally opened, the cover member 202 is accommodated in a state where the main board 11 is mounted on the front side of the cover member 202 so as to cover the mounting surface 11a. As long as the main board 11 is not removed from the mounting board 11a, the electronic parts such as the CPU 103 and the ROM 101 mounted on the mounting surface 11a cannot be illegally operated.

  Next, as shown in FIG. 10A, the back surface 11b of the main substrate 11 attached to the front surface side of the cover member 202 is opposed to the back surface of the base plate 201a of the base member 201, and the right side wall 201c of the base member 201 is The cover member 202 is brought close to the base member 201 so that the right side wall 202 c of the cover member 202 protrudes, and each engagement piece 220 of the cover member 202 is inserted from the open end of each engagement groove 250 of the base member 201. At this time, the outer surface of the side wall 201b of the base member 201 is covered by the right side wall 202c of the cover member 202, and the side wall 201b of the base member 201 is sandwiched between the side wall 202b of the cover member 202 and the guide wall 217. The cover member 202 is guided to move in the left-right direction with respect to the member 201. Thus, the cover member 202 is disposed at the first position shifted to the right side with respect to the base member 201. The first position is a detachable position where the cover member 202 can be detached from the back side with respect to the base member 201. By disposing the cover member 202 in the detachable position, the opening of the base member 201 can be opened. In a disengageable state (disengaged state).

  When the cover member 202 is slid from the first position toward the left side, each engagement piece 220 comes into contact with the end of each engagement groove 250 as shown in FIG. The left end portion of the side welded portion 223 is disposed at a second position where the sliding movement is restricted by contacting the covering wall 267. At this time, the locking pieces 203 and 203 of the base member 201 are inserted into the locking holes 222 and 222 of the cover member 202 on the right short side. On the left short side, the screw covering piece 602 is locked to the locked piece 602a of the base member 201, the locking piece 603 is locked to the locked piece 603a of the base member 201, and the cover side The left end portion of the welded portion 223 is accommodated in the accommodating recess 268 of the covering wall 267 and abuts against the inner wall of the accommodating recess 268 (see FIG. 15D).

  Further, the protrusion 215 formed on the side wall 201b is fitted into the concave groove 216 formed on the guide wall 217 so that the cover member 202 cannot move from the second position to the first position unless an external force exceeding a predetermined value is applied. become. Since the right portion of the protruding surface of the protrusion 215 has a larger inclination angle with respect to the side wall 201b than the left portion, when the cover member 202 is moved from the first position to the second position with respect to the base member 201, the guide wall 217 The right end is not easily caught by the protrusion 215, and when the cover member 202 is moved from the second position to the first position with respect to the base member 201, the fitting state is released by the inner surface of the groove 216 contacting the protrusion 215. It becomes difficult to be done.

  Thus, by arranging the cover member 202 in the second position, the cover member 202 is assembled to the base member 201, and the base member 201 and the cover member 202 are aligned (combined). It will be in the closed state (locking state) by which an opening is closed, and will be in the state which can be sealed later. The second position is a separation regulating position where the separation of the cover member 202 to the back side of the base member 201 is regulated by the engagement pieces 220 being engaged with the engagement grooves 250. . In addition, each engagement piece 220 and each engagement groove 250 constitute a slide movement support unit that supports (guides) the cover member 202 slidably between the first position and the second position with respect to the base member 201. To do.

  As described above, in order to change the substrate case 200 of this embodiment from the closed state to the open state, first, the cover member 202 is slid from the second position to the first position side along the base plate 201a of the base member 201. Otherwise, the locked state of the cover member 202 with respect to the base member 201 cannot be released, and the detachment of the cover member 202 from the base member 201, that is, the lifting, is effectively restricted by the locking action.

  Further, in the closed state, the mounting hole 234 of the sealing piece 230 is disposed at a position facing the screw hole 210, the mounting hole 227 is disposed at the position facing the screw hole 209, and the mounting hole 610 is formed in the cover side sealing portion 224. The cover-side welded portion 223 is disposed at a position opposite to the base-side welded portion 207 (see FIG. 15D).

  Here, for example, when the manufacturer of the pachinko gaming machine 1 stores the main board 11 in the board case 200 and ships to a game shop or the like, the cover side welding part 223 which is the welding part and the base side welding are provided. The part 207 is brought into a sealed state (also referred to as a first sealed state) by, for example, ultrasonic welding (caulking) using an ultrasonic welding machine or the like. As described above, since the cover-side welded portion 223 and the base-side welded portion 207 are welded, the sliding movement of the cover member 202 relative to the base member 201 from the second position to the first position side is restricted. The cover member 202 cannot be opened unless at least a part of the cover 201 or the cover member 202 is destroyed. That is, when the substrate case 200 is opened, a sealed state (first sealed state) remains. .

  In addition, after the closing screw 226 is inserted into the mounting hole 610 from the front side and screwed into the screw hole 611 of the cover side sealing portion 224, the sealing seal 400 (straddling the cover side sealing portion 224 and the base side sealing portion 229 is straddled. (See Fig. 3). In this way, by sticking the seal sticker 400 so as to straddle the cover side seal part 224 and the base side seal part 229, the cover member 202 is sealed when the base member 201 is slid from the second position to the first position. Since the seal 400 is broken, when the substrate case 200 is opened, it becomes a sealed state (also referred to as a second sealed state or a sealed state) in which traces remain.

  In addition, a U-shaped seal protective cover 228 (see FIG. 3) made of a synthetic resin material having translucency is attached so as to sandwich the cover member 202 and the base member 201 so as to cover the attached seal seal 400, The one-way screw 219 attached to the sealing piece 228a (see FIG. 3) protruding from the lower surface of the seal protection cover 228 is inserted into the insertion hole 218 of the cover member 202, and the screw member 222c inserted into the locking cylinder 222b. The seal protective cover 228 is attached to the cover member 202 by being screwed into a screw hole (not shown) of (see FIG. 3).

  That is, once the one-way screw 219 is attached to the screw hole of the screw member 222c (see FIG. 3), even if a tool such as a screwdriver is inserted into the operation groove, the one-way screw 219 cannot be rotated in reverse. Since it is an attachment member that cannot be removed from the connector, it cannot be removed unless the connecting piece or the like of the sealing piece 228a is cut (broken). Therefore, unless the sealing piece 228a is cut and separated from the seal protection cover 228, the seal protection cover 228 cannot be removed and the cover member 202 cannot be opened. That is, when the substrate case 200 is opened, the trace is left. The remaining sealing state (third sealing state) is obtained.

  In addition, after the sealing member 640 is fitted into the fitting recess 620d of the sealing piece 620, the one-way screw 623 attached from the rear side to the attachment hole 620c is screwed into the screw hole 642, thereby the sealing member 640. Is attached to the sealing piece 620.

  Specifically, as shown in FIG. 12 (A), when the sealing member 640 is attached to the sealing piece 620, the protrusion 640b is inserted into the fitting portion formed by the fitting recess 620d and the notch recess 206, Part of the cylindrical portion 640a and the protruding portion 640b are fitted into the fitting recess 620d. As a result, the restriction protrusion 641 is inserted into the restriction hole 624. The fitting recess 620d is formed in a non-circular shape when viewed from the front, and the two restricting protrusions 641 are inserted into the restricting holes 624, so that the mounting hole 620c of the sealing member 640 with respect to the sealing piece 620 is centered. Rotation is restricted (see FIG. 12C).

  As shown in FIG. 12B, in a state where the sealing member 640 is held by the sealing piece 620, the one-way screw 623 is inserted into the mounting hole 620c and screwed into the screw hole 642, whereby the sealing member 640 is attached to the sealing piece 620. The sealing member 640 is disposed so as to protrude toward the base member 201 when attached to the sealing piece 620.

  Thus, by assembling the base member 201 and the cover member 202 and attaching the sealing member 640 to the sealing piece 620 in a state where the cover member 202 is disposed at the second position with respect to the base member 201, As shown in FIG. 13A, when the cover member 202 is slid from the second position to the first position side (left side in FIG. 13) with respect to the base member 201, the inclined surface of the rib 645 of the sealing member 640 is obtained. When 645b contacts the left side wall 201d of the base member 201, the sliding movement of the cover member 202 relative to the base member 201 toward the first position is restricted.

  That is, when the cover member 202 is moved in the opening direction with respect to the base member 201 while being held by the sealing piece 620, the sealing member 640 contacts the base member 201 and opens the cover member 202 ( It is arranged at a position where the sliding movement to the first position side) can be prevented. Further, for example, unlike the case where the one-way screw 623 attached to the sealing piece 620 is screwed into the base member 201, the sliding movement of the cover member 202 relative to the base member 201 to the first position side is restricted. The stop member 640 is not connected to the base member 201 while being held by the sealing piece 620, and is disposed separately from the base member 201.

  Specifically, the cover member 202 is supported by the slide movement support means including the engagement piece 220 and the engagement groove 250 so as to be slidable between the first position and the second position with respect to the base member 201. Thus, since it cannot be detached from the base member 201 unless it is moved to the first position, the sealing member 640 comes into contact with the base member 201 and the cover member 202 is moved from the second position to the first position, that is, in the opening direction. If it cannot be moved, the substrate case 200 cannot be opened. Thus, by assembling the base member 201 and the cover member 202 and attaching the sealing member 640 to the sealing piece 620 in a state where the cover member 202 is disposed at the second position with respect to the base member 201, As shown in FIG. 13B, the connecting piece 621 is cut and the sealing piece 620 and the sealing member 640 cannot be opened unless they are separated from the cover member 202. That is, when the opening is opened, the trace is left. It will be in the remaining sealing state (4th sealing state).

  In this embodiment, the manufacturer places the board case 200 in the first to fourth sealing states at the manufacturing stage, and then ships to a game shop or the like. Even if it is not shipped after shipment, it may be shipped in at least one of the first to fourth sealed states, or may be shipped without any sealed state. .

  In addition, since the sealing member 640 is attached to the sealing piece 620 by the one-way screw 623, it is difficult to remove the sealing member 640 by removing the one-way screw 623, but the user can pick and rotate the sealing member 640. Thus, it is conceivable to remove the one-way screw 623 from the sealing piece 620. However, the fitting recess 620d and the sealing member 640 are formed in a non-circular shape, the two restricting protrusions 641 are inserted into the restricting holes 624, and the protrusion 640b is formed by the fitting recess 620d and the notch recessed portion 206. Since the rotation of the sealing member 640 relative to the sealing piece 620 is restricted by being inserted into the fitted portion, the sealing member 640 is rotated relative to the sealing piece 620 as described above. Removal of the one-way screw 623 from the sealing piece 620 can be prevented.

  Further, since the rib 645 of the protrusion 640b has a sloped surface 645b and is formed in a wedge shape, as shown in FIG. 13A, when the cover member 202 is moved to the first position side. The inclined surface 645b comes into contact with the left side wall 201d obliquely. Therefore, when the cover member 202 is slid, the inclined surface 645b is gradually pressed into contact with the left side wall 201d, so that the sealing member 640 and the connecting piece 621 are prevented from being damaged by an impact when the cover member 202 is touched. .

  In addition, when the cover member 202 is slid, the inclined surface 645b rides on the notch recess 206 of the left side wall 201d, so that the friction of the engagement piece 220 with respect to the engagement groove 250 gradually increases and is difficult to slide. Therefore, opening can be made difficult.

  Further, since the concave groove 630 described above is formed at a position corresponding to the notch concave portion 206 in the left side wall 201d, the cover member 202 is forcibly slid to the first position side in the fourth sealing state. Since the left side wall 201d is easily damaged, it is easy to find that there is a possibility that the left side wall 201d has been opened illegally.

  In addition, after the fourth sealing state is set, for example, when it is necessary to release the fourth sealing state for inspection of the main substrate 11, the connecting piece 621 is cut as shown in FIG. By cutting with CT or the like, the sealing member 640 is separated from the cover member 202 together with the sealing piece 620, so that the cover member 202 can be moved to the first position side. As described above, the sealing member 640 is held only by the cover member 202 of the base member 201 and the cover member 202 by the one-way screw 623 and attached by connecting the base member 201 and the cover member 202 by the one-way screw 623. It is not a thing.

  Therefore, when the connecting piece 621 is cut by the cutter CT or the like, the sealing member 640 is separated from the cover member 202 together with the sealing piece 620, and the sealing member 640 does not remain on the base member 201 side as in the past. When the cover member 202 is returned to the second position after being opened illegally, the cut trace does not become difficult to understand.

  In addition, after the first sealing state, for example, when it is necessary to release the first sealing state for inspection of the main substrate 11, the cover-side welded portion 223 needs to be separated from the cover member 202. The base side welded part 207 and the cover side welded part 223 cannot be welded again to obtain the first sealed state. In addition, when it is necessary to release the second sealing state, it is difficult to peel the sealing seal 400 so as not to break, and thus the second sealing state cannot be achieved. Further, when it is necessary to release the third sealing state, it is necessary to separate the sealing piece 228a from the seal protection cover 228. Therefore, the sealing piece 228a is connected to the seal protection cover 228 to obtain the third sealing state. Can not do it. Further, when it is necessary to release the fourth sealing state, it is necessary to separate the sealing piece 620 from the cover member 202. Therefore, the sealing piece 620 is connected to the cover member 202 to be in the fourth sealing state. I can't.

  Thus, when the 1st-4th sealing state is cancelled | released, it can be set as a sealing state again using the sealing piece 230. FIG. In this case, first, the mounting hole 234 of the sealing piece 230 in the cover member 202 matches the screw hole 210 in the closed state. Here, when the one-way screw 240a accommodated in the sealing piece 230 is screwed into the screw hole 210 by a screwdriver, the cover member 202 is attached to the base member 201 so as not to be detached.

  That is, once the one-way screw 240a is attached to the screw hole 210, even if a tool such as a screwdriver is inserted into the operation groove, the one-way screw 240a cannot be reversely rotated, that is, cannot be removed from the screw hole 210 again. Therefore, the substrate case 200 cannot be opened unless a predetermined portion of the substrate case 200 (for example, the connecting piece 233 of the sealing piece 230) is cut (broken), that is, the substrate case 200 is opened. In such a case, a sealed state (fifth sealed state) in which the trace remains is obtained.

  Further, when the substrate case 200 is opened for the inspection of the main substrate 11 or the like, not only the connecting piece 233 of the sealing piece 230 needs to be cut, but also the one-way screw 240a screwed into the screw hole 210 and the cover member 202. Since the cylindrical portion of the sealing piece 230 cut off from the base member 201 remains without being removed from the base member 201, the one-way screw 240 a is attached to the sealing piece 230 and cannot be attached to the base member 201 in the same manner. .

  Next, the case where a 1st sealing state is cancelled | released is demonstrated based on FIGS. As shown in FIG. 14, the cover-side welded portion 223 is opposed to the back side of the base-side welded portion 207 by sliding the cover member 202 from the first position to the second position with respect to the base member 201. The Further, the insertion piece 264 is inserted into the connecting cylinder portion 286 from the opening 287.

  As shown in FIG. 15A, when the substrate case 200 is opened after the first sealing state is established, the tool is connected to the connecting portions 280a and 280b of the cover member 202 using a tool such as a cutter CT, a nipper or a thread saw. If the cover side welded part 223 fixed to the base side welded part 207 is cut off from the main body of the cover member 202 by cutting the tube part 286, the cover side welded part 207 remains in the state where the cover side welded part 223 remains. The member 202 can be opened by sliding to the first position side.

  In the first sealing state, the connecting portions 280a and 280b are covered with the covering wall 267 when the cover member 202 is disposed at the second position, so that the connecting portions 280a and 280b are cut with the cutter CT. Since it is difficult to insert the cutter CT into the housing recess 268 inside the 267, there is a high possibility that the cutter CT will be cut together with the covering wall 267. Therefore, when the connecting portions 280a and 280b are cut and opened, there is a high possibility that a cut trace remains on the covering wall 267, so that it is easy to find that there is a possibility of opening.

  Further, when the connecting cylinder portion 286 is cut using the gap S1, as shown in FIG. 14B, the cover member 202 slides in the sliding direction of the connecting cylinder portion 286 from the back side of the connecting cylinder portion 286. It is conceivable that the cutter CT is arranged in a substantially orthogonal direction, and cut and cut while reciprocating the cutter CT up and down toward the front side. In this case, since the periphery of the insertion piece 264 is covered with the connection cylinder part 286, when the cutter CT is cut toward the front side, the insertion piece 264 is easily cut along with the connection cylinder part 286.

  However, if the insertion piece 264 is not cut together with the connecting tube portion 286 when it is attempted to open it illegally, traces of the unauthorized opening are conspicuous, and therefore the connecting tube portion 286 is not cut or damaged. It is conceivable to try to disconnect.

  As shown in FIG. 16, outer surfaces 286 a to 286 c that are opposed surfaces facing the insertion piece 264 in the connecting cylindrical portion 286, and outer surfaces 264 a to 264 c that are opposed surfaces facing the connecting cylindrical portion 286 in the insertion piece 264 are: It is a non-flat surface having a convex part or a concave part in part. Specifically, the outer surfaces 264a to 264c, which are opposing surfaces of the insertion piece 264, which is a connecting portion, are connected by a virtual straight line (eg, virtual straight line L1) that connects any two points (eg, P1 and P2) on the opposing surface. It has a convex part (for example, a corner part of insertion piece 264) which protrudes in the cylinder part 286 side.

  Therefore, in order to cut the connecting tube portion 286 without damaging the insertion piece 264, it is necessary to cut the blade of the cutter CT from three sides along the outer surfaces 286a to 286c as shown in FIG. It is extremely difficult to insert and apply the cutter CT from the front side to the connecting tube portion 286 on the front side in the space surrounded by the support plates 270a and 270b, and the connection tube portion 286 and the insertion piece 264 face each other. It becomes difficult compared with the case where the surface is a single flat surface. Further, since these outer surfaces 264a to 264c and 286a to 286c are arranged close to each other, if the blades of the cutter CT protrude even slightly from the outer surfaces 286a to 286c, the outer surfaces 264a to 264c are damaged, so that traces of cutting remain. It becomes easy.

  In addition, the cutting trace formed in the insertion piece 264 can be visually recognized through the connection cylinder part 286 because the connection cylinder part 286 is formed of a permeable member. Further, the insertion piece 264 and the insertion hole 321 do not have to be rectangular in sectional view, may be substantially circular in sectional view, and can be variously changed.

  Moreover, the opposing surface of a connection part and a connection corresponding | compatible part may be formed in the curved surface instead of the flat surface. That is, the facing surface is not limited to one formed by a plurality of flat surfaces (for example, the outer surfaces 264a to 264c, 286a to 286c) or a curved surface as described above, but may be composed of a single flat surface. Good. For example, the opposing surface may be formed in a substantially arc shape in a side view, may be formed in an uneven shape, or may be formed in a mountain-and-valley shape. Further, in the above, one opposing surface of the connecting portion and the connecting corresponding portion is provided so as to cover all of the other opposing surface. For example, any one of the outer surfaces 286a to 286c of the connecting cylinder portion 286 is provided. May be provided so as to cover at least a part, such as open.

  As described above, the board case 200 of the pachinko gaming machine 1 as an embodiment of the present invention has the base member 201 as the first member and the cover member 202 as the second member, and is the main board as the circuit board. After assembling the substrate case 200 for housing the substrate 11, the fitting recess 620d of the sealing piece 620 as the sealing member holding portion provided in the base member 201, the base member 201 and the cover member 202, the sealing piece And a sealing member 640 that places the substrate case 200 in the fourth sealing state by being held in the fitting recess 620d of 620, and the sealing member 640 is held in the fitting recess 620d of the sealing piece 620. In this state, when the cover member 202 is moved to the first position side that is the opening direction with respect to the base member 201, the cover member 202 abuts on the base member 201 to be in the first position side It is positioned to prevent movement of the.

  By doing so, when the connecting piece 621 is cut to open the substrate case 200, the sealing member 640 is completely separated from the cover member 202, and the base member 201 and the cover member 202 are assembled again. However, since the fitting recess 620d of the sealing piece 620 does not return to the state before cutting (the state before cutting cannot be reproduced), it is easy to discover that the substrate case 200 has been opened illegally.

  Further, the substrate case 200 supports the cover member 202 so as to be slidable from the second position, which is the sealing position, to the first position side over a predetermined section (for example, a section from the first position to the second position). An engagement piece 220 and an engagement groove 250 are provided as slide movement support means, and the sealing member 640 contacts the base member in the section from the first position to the second position and moves toward the first position side of the cover member 202. To prevent movement. Thus, the structure can be simplified because the sealing member 640 only has to abut against the base member 201 in the section where the cover member 202 is restricted to slide movement toward the first position by the slide movement support means.

  Further, the sealing member 640 is held by being attached to the fitting recess 620d of the sealing piece 620 by a one-way screw 623 that is a screw member, and the sealing member 640 rotates in the rotational direction of the one-way screw 623 with respect to the fitting recess 620d. Rotation restricting means (for example, formed by a non-circular fitting recess 620d and a sealing member 640, two restriction projections 641 and a restriction hole 624, a fitting recess 620d and a notch recess 206). By providing the fitting portion and the protrusion portion 640b, it is possible to prevent the one-way screw 623 from being removed from the fitting recess 620d by rotating the sealing member 640.

  The projection 640b of the sealing member 640 has a wedge-shaped portion (for example, a portion where the inclined surface 645b is formed in the rib 645), and the wedge-shaped portion moves the cover member 202 to the first position side. Since the sealing member 640 is gradually brought into contact with the base member 201 by contacting the base member 201 and preventing the movement toward the first position side, the cover member 202 is fitted by the impact of the contact. Damage to the joint recess 620d and the sealing member 640 can be prevented.

  In addition, the sealing member 640 has a protrusion 640b that fits into the notch recess 206 of the base member 201 while being held in the fitting recess 620d, so that the sealing member 640 is rotated to remove the one-way screw 623. In addition to this, it is possible to prevent damage to the fitting recess 620d of the cover member 202 and the sealing member 640 due to the impact of contact.

  The substrate case 200 includes a base-side weld portion 207 as a first fixing portion provided on the base member 201 and a second fixing portion connected to the cover member 202 via a connecting cylinder portion 286 as a connecting portion. A cover-side welded portion 223, and the base-side welded portion 207 and the cover-side welded portion 223 are fixed (for example, ultrasonic welded) to achieve the first sealed state. The member 201 has an insertion piece 264 as a connection corresponding portion that comes into contact with or closes to the connection cylinder portion 286 in a state where the cover member 202 is located at the second position that is the sealing position, and the connection cylinder portion 286 and the insertion piece H.264 has a shape corresponding to each other (see FIG. 16), and the outer surfaces 264a to 264c, which are one of the connecting cylinder 286 and the insertion piece 264, are arbitrary on the opposite surface. Point (e.g., P1, P2) virtual straight line (e.g., a virtual straight line L1) connecting with a corner portion of the insertion piece 264 of the protrusion protruding to the other side of.

  By doing in this way, when cutting the connection cylinder part 286 in order to cut | disconnect the cover side welding part 223 from the cover member 202 and cancel | release a sealing state, one of the connection cylinder part 286 and the insertion piece 264 is carried out. The outer surfaces 264a to 264c, which are opposing surfaces, are inserted pieces 264 as convex portions that protrude to the other side from a virtual straight line (for example, virtual straight line L1) connecting any two points (for example, P1 and P2) on the opposing surface. With this corner portion, it becomes difficult to cut along the facing surface, and the insertion piece 264 that is close to or in contact with the connecting tube portion 286 is easily cut together. Therefore, since the trace of cutting is likely to remain not only in the connecting cylinder portion 286 but also in the insertion piece 264, it is easy to discover that there is a possibility that the sealing state has been illegally released.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above-described embodiment, the cover member 202 is slidably provided between the first position and the second position with respect to the base member 201, and the sealing member 640 is provided on the cover member 202 that is moved when opening. Although the present invention is not limited to this, the present invention is not limited to this. For example, a substrate case 200A as Modification Example 1 shown in FIG. The member 640 may be held by a sealing piece 620 provided on the base member 201. In this case, the cover member 202 is moved when the cover member 202 is slid to the first position side with respect to the base member 201. It should just be arrange | positioned on the track | orbit when moving the cover member 202 to a 1st position side, ie, the position which contact | abuts and prevents the movement to the 1st position side of this cover member 202

  That is, in the substrate case 200 that is opened by moving one of the base member 201 and the cover member 202 with respect to the other, the sealing member 640 is a sealing piece provided on the cover member 202 that is moved when opening. In addition to what is held by 620, it may be held by the sealing piece 620 provided on the base member 201 that is not moved when opening.

  Moreover, in the said Example, although the base member 201 and the cover member 202 were supported so that sliding movement to the area between a 1st position and a 2nd position was carried out, this invention is limited to this. Instead, for example, as in the case 2B of the second modification shown in FIG. 18A, the cover member 202 is shown in a predetermined section from the sealing position with respect to the base member 201 (for example, a solid line in FIG. 18A). Rotation shaft 650 provided on the cover member 202 and a bearing provided on the base member 201 as rotation support means for supporting the rotation in the opening direction over a rotation section from a position to a position indicated by a two-dot chain line). In the structure including the portion 651, the sealing member 640 may abut against the base member 201 in the predetermined section to prevent the cover member 202 from moving in the opening direction.In this manner, the sealing member 640 contacts the base member 201 and rotates in a section where the movement of the cover member 202 in the opening direction relative to the base member 201 is restricted by the rotation support means. Since it is sufficient that the movement is restricted, the structure can be simplified.

  Further, in the substrate case 200B shown in FIG. 18A, the sealing member 640 is provided on the sealing piece 620 provided on the cover member 202 side, but the substrate of Modification 3 shown in FIG. 18B. As in the case 200C, the cover member 202 is opened relative to the base member 201 from a sealing position over a predetermined section (for example, a rotating section from a position indicated by a solid line to a position indicated by a two-dot chain line in FIG. 18A). As the rotation support means for supporting the rotation toward the surface, a rotation shaft 650 provided on the base member 201 and a bearing portion 651 provided on the cover member 202 are provided. It may be provided on the sealing piece 620 provided on the cover member 202 rotated with respect to 201.

  Moreover, in the said Example and the modifications 1-3, the cover member 202 extends over a predetermined area with respect to the base member 201 by a slide movement support means or a rotation support means in a predetermined area from a sealing position (2nd position). However, the present invention is not limited to this, and the predetermined section has a sealing position as in the above-described embodiment and the first to third modifications. It may be supported in a part of the section from the opening position to the opening position, or may be supported in the entire section from the sealing position to the opening position.

  Further, when the substrate case 200 is opened, the cover member 202 may be opened even if the cover member 202 is moved in an arbitrary direction with respect to the base member 201 material. Even in such a case, even when the cover member 202 is moved in an arbitrary opening direction, the sealing member is in a position where it can abut against the base member 201 and prevent the cover member 202 from moving in the opening direction. It only has to be arranged.

  Further, in the embodiment, when the cover member 202 is slid from the second position to the first position side with respect to the base member 201, the movement of the sealing member 640 comes into contact with the base member 201 to be restricted. It was. That is, the cover member 202 is in a state in which it can hardly move to the first position side at the second position by the sealing member 640. However, the present invention is not limited to this, for example, the base member by sliding movement. If the cover member 202 is in a state where the cover member 202 can be detached from the main member 201 or the main board 11 is not released so that it is not easy to perform an illegal act, the cover member 202 moves toward the first position with respect to the base member 201. The movement may be regulated by the sealing member 640 when it moves by a predetermined amount (for example, when it moves between the second position and the first position).

  Moreover, in the said Example, although the fitting recessed part 620d of the sealing piece 620 connected with the main body of the cover member 202 via the connection piece 621 was described as an example of the sealing member holding | maintenance part, this invention was described. However, the sealing member holding portion may be provided on the main body of the cover member 202 without a connecting piece or the like. Further, although the sealing piece 620 is provided outside the cover member 202, it may be provided inside the cover member 202.

  Moreover, in the said Example, the sealing member 640 cannot be removed unless the connection piece 621 etc. of the sealing piece 620 are cut | disconnected (destroyed) with the one-way screw 623. In other words, a trace will remain when it is removed. The board case 200 can be brought into a sealed state by being attached to the sealing piece 620, but the present invention is not limited to this, and the sealing member 640 is a base member. If the substrate case 200 can be brought into a sealed state by being held by the sealing piece 620 after the 201 and the cover member 202 are assembled, for example, an ultrasonic wave is applied to the sealing piece 620. It may be fixed by welding or the like, or may be attached to the sealing piece 620 by an attaching means other than a one-way screw. May be locked to Futomehen 620 by the locking means can not be released. Further, instead of the sealing member 640, for example, a part of the one-way screw 623 protruding from the sealing piece 620 may be used.

  In the embodiment, the main board 11 on which the game control microcomputer 100 for controlling the game is mounted is described as an example of the circuit board. However, the effect control microcomputer for controlling the effect is mounted. Other circuit boards such as the effect control board 12 may be used.

  Further, in the substrate case 200 and the seal sticker 400 in the above embodiment, a serial number that is identification information for identifying each main board 11 and the seal sticker 400 may be displayed (printed). By doing in this way, it can be made easy to recognize which main substrate 11 and the seal seal 400 are installed. In addition, as identification information for identifying each main substrate 11 and the seal sticker 400, the identification information is encoded, thereby displaying (printing) a two-dimensional code readable by a predetermined reader. You may do it.

  FIG. 19A is a diagram showing a serial number and a two-dimensional code displayed (printed) as identification information on the identification information table portion of the seal sticker 400. In FIG. 19A, the serial number and the two-dimensional code can be read visually.

  As described above, if the identification information (serial number or two-dimensional code) is displayed (printed) so as to be visually readable, it may be easily copied and misused. Therefore, the film member 2000 is affixed on the display of the identification information as shown in FIG. 19B so that the display of the identification information (serial number or two-dimensional code) is difficult or impossible to see. Also good.

  The film member 2000 can be seen through by seeing through a specific visualization member 3000 as shown in FIG. 20A, and the serial that has been difficult or impossible to see by the film member 2000. Any display that can visually recognize the number, the two-dimensional code, or the like may be used.

  The film member 2000 shown in FIG. 19B includes, for example, an optically transparent adhesive layer, a circular polarizing filter layer provided on the adhesive layer, and a cholesteric liquid crystal layer provided on the circular polarizing filter layer. Any multi-layered member may be used.

  The circular polarizing filter layer has a left circle on the observation surface side (opposite side of the adhesive layer in the film member) when natural light is incident from the adhesive layer side (identification information side when the film member is attached to the seal). It is adjusted to selectively transmit polarized light.

  The cholesteric liquid crystal layer is embossed to perform hologram display. Here, the rotational direction of the circularly polarized light selectively reflected by the cholesteric liquid crystal layer and the rotational direction of the circularly polarized light transmitted through the circularly polarizing filter layer from the adhesive layer side to the observation surface side are set in opposite directions. Yes. That is, the cholesteric liquid crystal layer selectively reflects right circularly polarized light, and the left circularly polarized light is selectively transmitted from the adhesive layer side toward the observation surface side.

  The visualization member 3000 shown in FIG. 20A may be made of, for example, a left circular polarization filter.

  When viewing the identification information display part to which the film member 2000 is attached, the hologram display is visually recognized as shown in FIG. In this case, the hologram display becomes an obstacle, and the serial number and the two-dimensional code as identification information cannot be visually recognized. The serial number and the two-dimensional code need only be at least difficult to visually recognize by hologram display, and may not be completely invisible. The two-dimensional code may be almost visually recognizable if it cannot be read by the reading device.

  Here, as shown in FIG. 20B, when the identification information display part to which the film member 2000 is attached is visualized through the visualization member 3000 made of a left circular polarization filter, the reflected light from the cholesteric liquid crystal layer is visible. Can not. On the other hand, the left circularly polarized light contained in the reflected light from the serial number or the two-dimensional code as identification information is transmitted through the circularly polarizing filter layer, the cholesteric liquid crystal layer, and the left circularly polarizing filter. That is, when viewing through the visualization member 3000 made of the left circular polarization filter, the hologram display is not visually recognized, and the serial number and the two-dimensional code as identification information can be clearly recognized. The two-dimensional code can be read by a reading device through a visualization member including a left circular polarization filter.

  Thus, on the display of the identification information display unit, the film member 2000 that makes it difficult or impossible to visually recognize a serial number, a two-dimensional code, or the like when pasted without a specific visualization member 3000 is pasted. Thus, it is possible to prevent the identification information from being read by a third party with a simple configuration. Moreover, since a display can be visually recognized only by visually observing through the visualization member 3000, it can suppress that the confirmation work of the display by an administrator becomes troublesome.

  Although the example which affixes the film member 2000 on the seal seal | sticker 400 was shown, you may affix on any location of a slot machine or a pachinko game machine. For example, it may be affixed to the substrate case instead of directly affixing to the seal seal, and as a result, the display of the seal seal may be difficult or impossible to visually recognize. In addition, if identification information such as a production number is displayed on the game board, the identification information such as the production number may be difficult or impossible to visually recognize by attaching the film member 2000 to the game board. Good.

  The identification information display unit to which the film member 2000 is affixed is preferably a flat surface part capable of closely attaching the visualization member 3000. Since the visualization member 3000 can be in close contact, the identification information can be confirmed smoothly.

  It is desirable that a space for bringing the visualization member close is provided around the identification information display unit to which the film member 2000 is attached. By providing such a space, the identification information can be confirmed smoothly.

  Although the film member 2000 has been described as having an adhesive layer and being attached, it may be placed on the identification information display unit without having an adhesive layer. In this case, it is preferable to provide a holding member for holding the film member 2000 around the identification information display unit or the identification information display unit.

  FIG. 19B shows an example in which one film member 2000 is pasted on the display of the identification information display unit, but a plurality of film members 2000 such as pasting a film member 2000 for each identification information display unit. You may make it stick. At this time, as each film member 2000, you may use the film member 2000 which becomes visible by the different visualization member 3000. FIG. Thereby, security can be improved.

  You may make it provide the holding member for hold | maintaining the visualization member 3000 in the vicinity of the identification information display part to which the film member 2000 is affixed. Thereby, since the administrator who is going to confirm the information displayed on the identification information display part can confirm in a state where the visualization member 3000 is held on the holding member, the confirmation work is facilitated. In particular, when reading a two-dimensional code, the work is carried by holding a reading device. Therefore, the work efficiency can be improved by holding the visualization member 3000 by the holding member.

  Further, in the above embodiment, the pachinko gaming machine 1 is illustrated as an example of the gaming machine, but the present invention is not limited to this. For example, a predetermined number of gaming balls are inside the gaming machine. The number of loaned balls that are enclosed in a circulating manner and lent in response to a loan request by a player and the number of prize balls that are awarded in response to winnings are added, while the number of game balls used in the game is subtracted. The present invention can also be applied to so-called enclosed game machines that are stored in the memory.

  In the above embodiment, a pachinko gaming machine is applied as an example of a gaming machine. However, for example, a game can be started by setting a predetermined number of bets for one game using a gaming value. At the same time, the display result is derived to a variable display device capable of variably displaying a plurality of types of symbols that can be identified, whereby one game is completed, and a prize is awarded according to the display result derived to the variable display device. The present invention can also be applied to slot machines that can be generated.

  In the above embodiment, a spherical game ball (pachinko ball) is applied as an example of the game medium. However, the present invention is not limited to the spherical game medium, and for example, a non-spherical game medium such as a medal. It may be.
