Description

  The present invention relates to a gaming machine that performs a game.

  A gaming machine such as a pachinko gaming machine or a slot machine is provided with a number of control boards (circuit boards) such as a game control board (circuit board) for controlling the game. A game control microcomputer including a CPU, RAM, ROM, and the like is mounted on the control board, and a program (game control program) for controlling the progress of the game is stored in the ROM. When the mounted microcomputer is replaced with a microcomputer in which a malicious program is written, it becomes possible to illegally pay out prizes.

  Therefore, this type of control board is stored in the board case, and when the board case is opened, it is in a sealed state so that the trace remains, and the control board may have been cheated. There are things that make it easier to discover.

  Moreover, as this kind of substrate case, it consists of a 1st covering body and a 2nd covering body, and the 1st covering body side adhering part of a 1st covering body is slid by moving with respect to a 1st covering body. And the second covering body side fixing portion of the second covering body can be fixed to be in a sealed state. In addition, for example, in order to confirm whether a board in which a shop clerk or the like is stored is replaced with an unauthorized board, the second covering body side fixing portion is connected to the second covering body via a connecting portion. In addition, by cutting the connecting portion in the sealed state, there is one in which the second covering body side fixing portion is separated from the second covering body so that the sealing state can be released (for example, Patent Documents) 1).

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 decorative LED may be arranged around each structure (for example, the normal winning ball device 6A, the normal variable winning ball device 6B, the special variable winning ball device 7, etc.) in the game area 10 of the pachinko gaming machine 1. . At the lower right position of the gaming machine frame 3, a hitting operation handle (operation knob) operated by a player or the like to launch a game ball as a game medium toward the game area 10 is provided. For example, the hitting operation handle adjusts the resilience of the game ball according to the operation amount (rotation amount) by the player or the like. The hitting operation handle only needs to be provided with a single shot switch or a touch ring (touch sensor) for stopping driving of a shooting motor provided in a hitting ball shooting device (not shown).

  A gaming ball paid out as a prize ball or a gaming ball lent out by a predetermined ball lending machine can be supplied to a predetermined position of the gaming machine frame 3 below the gaming area 10 to a launching device (not shown). An upper plate (hit ball supply tray) that is held (stored) is provided. Below the gaming machine frame 3, there is provided a lower plate that holds (stores) surplus balls overflowing from the upper plate so as to be discharged to the outside of the pachinko gaming machine 1.

  For example, a stick controller 31A that can be held and tilted by the player is attached to a member that forms the lower plate, for example, at a predetermined position on the front side of the upper surface of the lower plate main body (for example, a central portion of the lower plate). Yes. The stick controller 31A includes an operation stick that the player holds, and a trigger button is provided at a predetermined position of the operation stick (for example, a position where the index finger of the operator is hooked when the player holds the operation stick). Yes. The trigger button can be operated in a predetermined direction by performing a push-pull operation with a predetermined operation finger (for example, an index finger) in a state where the player holds the operation stick of the stick controller 31A with an operation hand (for example, the left hand). What is necessary is just to be comprised. 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 inside the lower plate body or the like below 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.

  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 the necessary initial setting after setting the interrupt prohibition. 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 has been 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.

  The cover-side weld portion 223 formed in this manner is a weld plate that is connected to the rear sides of the support plates 270a and 270b that extend to the left side from the side wall 202d of the cover plate 202a via connection pieces 280a to 280d. The unit 271 is provided. Specifically, the welding plate portion 271 is substantially omitted from a front view 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 wall portion of the side wall 202d and the inner surfaces of the support plates 270a and 270b. They are arranged with a U-shaped gap S1 therebetween.

  The connecting pieces 280a and 280b connect the support plate 270a and the welding plate portion 271 and the connecting pieces 280c and 280d connect the support plate 270b and the welding plate portion 271. That is, the connecting pieces 280 a to 280 d 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 pieces 280a to 280d is formed in a plate shape as shown in FIG. 7, and a gap S1 is formed around the connecting pieces, so that it can be cut by a tool such as a cutter or a nipper. .

  On the front surface of the connecting piece 280a, a fitting convex part 281 having a substantially horizontally long rectangular shape in front view and a substantially semicircular shape in horizontal sectional view is formed with a guide piece 282 and a welding plate formed on the inner surface of the support plate 270a. It extends in the vertical direction, that is, in a direction orthogonal to the sliding movement direction of the cover member 202 relative to the base member 201 so as to straddle the portion 271. Specifically, as shown in FIG. 7C, the fitting convex portion 281 is formed to bend in the left-right direction so as to bulge to the front side, and is shorter than the vertical width dimension of the fitting concave portion 266. It has a width dimension, and can be fitted into the fitting recess 266 when the cover member 202 is located at the second position as described later (see FIG. 12A).

  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 attachment 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 if 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 illustrated in FIG. 8A, the back surface 11 b 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 201 a of the base member 201, and the short side 201 c of the base member 201 is The cover member 202 is brought close to the base member 201 so that the side wall 202c 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 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 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 insertion 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. 11B).

  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, the base member 201 and the cover member 202 are aligned (combined), and the opening of the base member 201 is obtained. Is in a closed state (locked state) where it is closed, and a state described later is possible. 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. .

  As described above, in order to change the substrate case 200 of the present embodiment from the closed state to the open state, first, the cover member 202 must be slid along the base plate 201a of the base member 201 unless the cover member 202 is slid. The locked state of the member 202 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 mounting 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 on the cover side sealing portion 224. The cover-side welded portion 223 is disposed at a position facing the base-side welded portion 207 (see FIGS. 8B and 9).

  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 is restricted. As a result, the cover member 202 cannot be opened unless at least a part of the cover member 202 is destroyed.

  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. A U-shape made of a synthetic resin material having translucency so as to cover the affixed sealing seal 400, as shown in FIG. The seal protection cover 228 (see FIG. 3) is mounted so as to sandwich the cover member 202 and the base member 201, and the seal seal 400 is protected and shipped.

  In this way, by sticking the seal seal 400 (see FIG. 3) so as to straddle the cover side seal portion 224 and the base side seal portion 229, the cover member 202 is moved from the second position to the base member 201. When the cover member 202 is opened, the seal state (second seal state) remains when the cover member 202 is opened because the seal sticker 400 is broken by the movement when it is slid to one position.

  In addition, after the sealed state, for example, when it is necessary to release the sealed state for inspection of the main substrate 11, it is necessary to separate the cover-side welded portion 223 from the cover member 202, so that the welding is performed again. I can't. In such a case, the sealing state can be set again using the attachment sealing piece 230. In this case, first, the mounting hole 234 of the mounting 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 attachment 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 is attached in an attached state that cannot be opened unless a predetermined portion of the substrate case 200 (for example, the connecting piece 233 of the attachment sealing piece 230) is cut (destroyed).

  Further, when opening the substrate case 200 for inspection of the main substrate 11, it is necessary not only to cut the connecting piece 233 of the mounting sealing piece 230, but also the one-way screw 240 a screwed into the screw hole 210 and the cover member. Since the cylindrical portion of the mounting sealing piece 230 cut from 202 remains unremovable from the base member 201, a one-way screw 240a is attached to the mounting sealing piece 230 and is similarly attached to the base member 201. It is not possible.

  Next, the detail of a 1st sealing state is demonstrated based on FIGS.

  As shown in FIGS. 15A and 15B, the connecting pieces 280a, 280b, and 280d as the connecting portions have a quadrangular prism shape, and the connecting pieces 265a to 265c are in a state where the cover member 202 is disposed at the second position. The adjacent facing surface 283 includes an outer surface 283a of the fitting convex portion 281 and a flat surface 283b formed around the fitting convex portion 281. That is, the facing surface 283 protrudes toward the connecting pieces 265a to 265c from a virtual straight line L1 that connects two points P1 and P2 on the flat surface 283b of the facing surface 283 and a virtual straight line L1 ′ that connects points P1 ′ and P2 ′. It has the fitting convex part 281 which is a convex part.

  On the other hand, the connection pieces 265a to 265c as the connection corresponding portions have a quadrangular prism shape, and the facing surface 269 close to the connection pieces 280a, 280b, and 280d in the state where the cover member 202 is disposed at the second position has a fitting recess. The inner surface 269a of the H.266 has a flat surface 269b formed around the fitting recess 266. That is, the opposing surface 269 is connected to the connecting pieces 280a, 280b, and 280d from the virtual straight line L2 connecting the two points P11 and P12 on the flat surface 269b and the virtual straight line L2 ′ connecting the two points P11 ′ and P12 ′. It has the fitting recessed part 266 which is a recessed part dented in the direction to leave | separate. Two points P11 and P12 on the flat surface 269b are two points P1 and P2 on the flat surface 283b, and two points P11 ′ and P12 ′ on the flat surface 269b are two points P1 ′ and P2 ′ on the flat surface 283b. It is a position corresponding to each.

  In other words, the facing surface 283 and the facing surface 269 are opposed to and close to each other in a state where the cover member 202 is disposed at the second position, and have shapes corresponding to each other. The shapes corresponding to each other need not be shapes that perfectly match each other when they are abutted with each other. It is only necessary to have a complementary relationship that supplements the other. Therefore, of the opposing surface 283 and the opposing surface 269, one of the opposing surfaces 283 is a fitting protrusion as a protruding portion that protrudes toward the connecting piece 265a side from a virtual straight line connecting two points on the flat surface 283b of the opposing surface 283. In the case of having the portion 281, the other facing surface 269 having a shape corresponding to the facing surface 283 is in a direction away from the connecting piece 280 a from an imaginary straight line connecting two points on the flat surface 269 b of the facing surface 269. It has the fitting recessed part 266 which is a recessed part to dent. Further, the facing surface 283 includes a convex outer surface 283a and a flat surface 283b, and the facing surface 269 includes a concave inner surface 269a and a flat surface 269b. That is, it is a non-flat surface.

  In other words, one of the facing surface 283 and the facing surface 269 is a recess that is recessed in a direction away from the connecting piece 280a from a virtual straight line connecting two points on the flat surface 269b of the facing surface 269. When the fitting recess 266 is provided, the other facing surface 283 having a shape corresponding to the facing surface 269 protrudes toward the connecting piece 265a from an imaginary straight line connecting two points of the flat surface 283b of the facing surface 283. It has the fitting convex part 281 as a convex part to do.

  As shown in FIGS. 10 to 12, when the cover member 202 is disposed at the first position with respect to the base member 201 and then slid from the first position toward the second position, the back surface of the base-side welding surface 261 a is displayed. The cover-side welding surface 271a is disposed to face the side, and the cover-side non-welding surface 271b is disposed to face the back side of the base-side non-welding surface 261b.

  Further, the connecting piece 280a is arranged to overlap the rear side of the connecting piece 265a, the connecting piece 280b is arranged to overlap the rear side of the connecting piece 265b, and the connecting piece 280d is overlapped to the rear side of the connecting piece 265c. Be placed. That is, the base member 201 includes the connection pieces 265a to 265c as connection corresponding parts that are close to the connection pieces 280a, 280b, and 280d as the connection parts in a state where the cover member 202 is located at the second position, and the connection piece 280a. , 280b, 280d, and the facing surfaces 269 of the connecting pieces 265a to 265c are arranged close to each other and facing each other.

  The connecting piece 280c does not overlap with any of the connecting pieces 265a to 265c. The left and right width dimensions of the connecting pieces 265a to 265c are longer than the connecting pieces 280a, 280b, and 280d. Further, the left side portion of the welding plate portion 271 of the cover side welding portion 223 and the left side portions of the connecting pieces 280b and 280d and the support plates 270a and 270b are accommodated in the accommodation recess 268. Then, the fitting convex portion 281 of the connecting piece 280a is fitted into the fitting concave portion 266 of the connecting piece 265a (see FIG. 12C).

  In this embodiment, when the cover member 202 is slid from the first position to the second position with respect to the base member 201, the engagement piece 220 is engaged with the engagement groove 250, but FIG. As shown in FIG. 3, the fitting convex portion 281 of the connecting piece 280a moves so as to slide on the rear end surface of the support plate 260b before being fitted into the fitting concave portion 266 of the connecting piece 265a, and then into the fitting concave portion 266. Mating. That is, when the fitting convex portion 281 reaches the support plate 260b, the fitting convex portion 281 rides on the rear end face and slides and then fits into the fitting concave portion 266.

  In a state where the fitting convex portion 281 is fitted in the fitting concave portion 266, when the cover member 202 is slid to the right side, the left side surface of the fitting convex portion 281 comes into contact with the inner surface of the fitting concave portion 266 so as to resist. Therefore, as will be described later, even when the connecting pieces 280a, 280b, and 280d are cut and the cover-side welded portion 223 is separated from the main body and the cover member 202 can be slid to the right, it is difficult to slide. .

  When an external force of a predetermined value or more is applied to the cover member 202 toward the right side, the fitting convex portion 281 deviates from the fitting concave portion 266, so that it can be slid from the second position toward the first position. After moving the cover member 202 to the second position in this manner, as described above, when the base-side welding surface 261a and the cover-side welding surface 271a are ultrasonically welded, the outer welding ridge 274 and the inner welding ridge 275 are formed. By melting, the base-side welding surface 261a and the cover-side welding surface 271a are integrated. That is, the welding plate portion 261 connected to the base member 201 via the connection pieces 265a to 265c and the welding plate portion 271 connected to the cover member 202 via the connection pieces 280a to 280d are welded and integrated. Is done.

  As a result, the sliding movement of the cover member 202 from the second position to the first position with respect to the base member 201 is restricted, and the deviation of the fitting convex part 281 from the fitting concave part 266 is restricted. Is opened, it becomes a sealed state (first sealed state) where traces remain.

  Next, based on FIG. 13, in order to release the sealed state (first sealed state), the connecting pieces 280a to 280d are cut using a tool such as a cutter CT (or a yarn saw), and the cover side welded portion A situation when the cover member 202 can be slid from the second position to the first position by separating 223 from the main body of the cover member 202 will be described. In the following, only the cutting state of the connecting piece 280a among the connecting pieces 280a to 280d will be described, and description of the cutting state of the other connecting pieces 280b to 280d will be omitted.

  As shown in FIG. 13, when cutting the connecting piece 280a, the cutter CT is arranged along the sliding movement direction of the cover member 202 from the back surface of the connecting piece 280a to the connecting piece 280a, and the cutter CT is directed toward the front side. While reciprocating left and right, cut and cut. Then, as shown in FIGS. 13A and 13B, the blade CTA of the cutter CT is cut until it reaches the flat surface 283b of the facing surface 283 and is close to the facing surface 269 (flat surface 269b) of the connecting piece 265a. When the cutting groove 290a is formed from the back surface of the connecting piece 265a to the flat surface 283b, the blade CTA of the cutter CT does not reach the front end of the fitting convex portion 281 in the connecting piece 280a, so the connecting piece 280a is They are integrated via the fitting convex portion 281. That is, it is not completely cut (see FIG. 13B).

  Here, since the blade CTA of the cutter CT is formed in a straight line shape, it is necessary to cut the cutter CT further to the front side as shown in FIG. 14 when attempting to cut to the front end of the fitting convex portion 281. However, since the fitting convex portion 281 enters the fitting concave portion 266, the positions near the left and right of the fitting concave portion 266 in the connecting piece 265a are also cut. That is, not only the connecting piece 280a but also the cutting grooves 290b and 290c (cutting traces) are formed not only on the connecting piece 265a but also on the left and right sides of the fitting recess 266 in the connecting piece 265a whose width is longer than the connecting piece 280a. 14A, even when the blade CTA of the cutter CT is cut while being inclined with respect to the flat surfaces 283b, 269b, the cutting grooves 290b, 290c (a trace of cutting) is formed. That is, traces of cutting remain on the facing surface 269 on the connecting piece 265a side.

  As described above, the facing surface 283 of the connecting piece 280a and the facing surface 269 of the connecting piece 265a are non-flat surfaces having convex portions and concave portions in part, so that the connecting piece 280a is not damaged so as not to damage the connecting piece 265a. In order to cut, it is necessary to cut the straight blade CTA of the cutter CT along the facing surface 283. However, the outer surface 283a of the fitting convex portion 281 is a curved surface, and when the fitting convex portion 281 is fitted into the fitting concave portion 266, the outer surface 283a of the fitting convex portion 281 can be visually recognized from the outside. Since it becomes difficult, it is more difficult to move and cut the blade CTA along this than to cut a flat opposing surface. Further, since these facing surfaces 283 and 269 are arranged close to each other, if the blade CTA of the cutter CT protrudes even slightly, the facing surface 269 of the connecting piece 265a is damaged, leaving a trace of cutting. It becomes easy.

  In this way, not only the connecting piece 280a on the cover member 202 side but also the cutting piece 265a on the base member 201 side is left with a cutting trace, so that the cutting grooves 290a to 290c which are the cut traces increase. In order to become conspicuous, when the connecting piece 280a is illegally cut by an unauthorized person, it is easy to find that there is a possibility that the connecting piece 280a has been illegally cut.

  As described above, the board case 200 of the pachinko gaming machine 1 according to the present invention is restricted from being removed from the base member 201 from the first position, which is a detachable position where the cover member 202 can be detached from the base member 201. The base side welded portion 207 and the cover side welded portion 223 can be welded to the first sealed state by cutting the connecting pieces 280a to 280d. Thus, the first sealing state can be released, and the base member 201 can be connected to the connection pieces 265a to 265c which are connection corresponding parts close to the connection pieces 280a, 280b, and 280d when the cover member 202 is located at the second position. The opposing surfaces 269 and 283 of the connecting piece 280a and the connecting piece 265a have shapes corresponding to each other, and the opposing surface 283 is the opposing surface 2 Two points on the flat surface 283b in the 3 P1, P2 connecting the virtual straight line L1 and the two points P1 ', P2' and has a fitting projection 281 projecting from the other side imaginary straight line L1 'connecting.

  By doing in this way, when cutting the connection pieces 280a to 280d in order to release the first sealing state by separating the cover-side weld portion 223 from the main body of the cover member 202, the connection pieces 280a and 265a One of the opposing surfaces 283 is a virtual straight line L1 connecting two points P1 and P2 on a flat surface 283b of an arbitrary opposing surface 283 on the opposing surface 283, or a virtual straight line L1 ′ connecting two points P1 ′ and P2 ′. By having the fitting convex portion 281 protruding further to the other side, it becomes difficult to cut along the facing surface 283, and the connecting piece 265a adjacent to the connecting piece 280a is easily cut together. Therefore, since traces of cutting are likely to remain not only in the connecting piece 280a but also in the connecting piece 265a, it is easy to discover that the first sealing state may be illegally released.

  In this embodiment, the virtual straight lines L1 and L1 ′ are virtual lines connecting two points on the flat surface of the facing surface 283 on the facing surface 283, but the present invention is not limited to this. Alternatively, it may be an imaginary straight line connecting any two points other than the flat surface as long as it is any two points on the facing surface.

  In this embodiment, the cover member 202 is provided with connecting pieces 280a to 280d as connecting portions, and the base member 201 is provided with connecting pieces 265a to 265c as connecting corresponding portions. The connecting member may be provided on the base member 201, and the connecting member may be provided on the cover member 202.

  In the present embodiment, four connecting pieces 280a to 280d as connecting portions are provided, but the present invention is not limited to this, and the number of connecting portions may be three or less, Five or more may be sufficient. Moreover, one may be sufficient.

  Further, in the present embodiment, one of the connection pieces 280a, 280b, 280d and the connection pieces 265a to 265c, one of the connection pieces 280a and the connection piece 265a, is flat on the opposite surface 283. Although it has the fitting convex part 281 which protrudes in the other side from the virtual straight line L1 which connects two points P1 and P2 on the surface 283b and the virtual straight line L1 'which connects two points P1' and P2 ', this invention is this. However, it is not limited to the above, and one of the other connecting pieces 280b and 280d and the connecting pieces 265b and 265c has a convex surface protruding to the other side from a virtual straight line connecting any two points on the opposing surface. May have a part. That is, the facing surfaces of the plurality of connecting portions and the corresponding connecting portions corresponding to the plurality of connecting portions each have a convex portion that protrudes to the other side from a virtual straight line connecting any two points on the facing surface. May be.

  In this embodiment, welding is described as an example of a method for fixing the base-side welded portion 207 and the cover-side welded portion 223, but the present invention is not limited to this, and the base-side welded portion. 207 and the cover-side welded portion 223 are integrated by assembling with a one-way screw 240a or the like. It may be.

  That is, as another example, for example, the second covering body side fixing portion may be the mounting sealing piece 230 and the first covering body side fixing portion may be the periphery of the screw hole 210 in the base member 201. In this case, the connecting portion is the connecting piece. 233, the connection corresponding portion is around the screw hole 210 in the base member 201, and one of the opposing surfaces of the connection piece 233 and the periphery of the screw hole 210 in the base member 201 is an arbitrary surface on the opposite surface. What is necessary is just to have the convex part which protrudes in the other side from the virtual straight line which connects two points.

  Further, in the present embodiment, the connection pieces 265a to 265c for connecting the main body of the base member 201 and the base-side welded portion 207 are described as an example of the connection corresponding portion, but the present invention is limited to this. Instead, the connection corresponding part may not be a connection piece or the like for connecting the main body of the base member 201 and the base-side welded part 207, but may be constituted by a flat plate part or the like.

  In this embodiment, the main board 11 is applied as an example of the circuit board. However, the present invention is not limited to this, and the circuit board is another circuit board such as the effect control board 12. May be.

  Further, the base member 201 has an accommodation recess 268 as an accommodation portion that accommodates at least a part of the cover-side weld portion 223 when the cover member 202 is slid to the second position, so that the cover-side weld portion 223 is accommodated. Since at least a part of the cover is covered with the housing recess 268 and it is difficult to release the fixed state between the base-side welded portion 207 and the cover-side welded portion 223, it is possible to suppress fraud.

  Further, the other facing surface 269 of the connecting piece 280a and the connecting piece 265a has a fitting recess 266 into which the fitting projection 281 of the one facing surface 283 is fitted, and the cover member 202 is moved from the second position. When sliding to the first position, the left side surface of the fitting convex portion 281 comes into contact with the inner surface of the fitting concave portion 266 so that resistance is applied. Therefore, as will be described later, the connecting pieces 280a, 280b, 280d are cut off. Even in a state where the cover-side welded portion 223 is separated from the main body and the cover member 202 can be slid to the right, it is difficult to slide. In this way, the connecting pieces 280a to 280d are cut, and in particular, even if the connecting piece 280a is completely cut to the fitting convex portion 281, the fitting convex portion 281 is fitted into the fitting concave portion 266. Thus, it is difficult to slide the cover member 202 to the first position side, so that it is possible to suppress fraud.

  Further, the fitting convex portion 281 is formed to extend from the connecting piece 280a to the welding plate portion 271 of the cover side welding portion 223 and the guide piece 282 formed on the inner surface of the support plate 270a of the cover member 202. The base member 201 side at a location where it is difficult to notice when it is cut, such as a boundary portion between the connecting piece 280a and the welding plate portion 271 of the cover side welding portion 223 or a boundary portion between the connecting piece 280a and the guide piece 282 of the cover member 202 This makes it easier to leave traces of cutting.

  Specifically, for example, as shown in FIG. 13C, the connecting piece 280a is arranged so that the cutter CT is along the edge 282a facing the left-right direction of the guide piece 282 or the edge 271d facing the left-right direction of the welding plate portion 261. When cut, the cutting groove 290a is formed on the extended line of the edge 282a and the edge 271d, so that the cutting groove 290a is less conspicuous than when the cutting groove 290a is formed at a position shifted forward and backward with respect to the edge 282a and the edge 271d. Therefore, it is conceivable that the unauthorized person tries to cut the connecting piece 280a along the edge 282a or the edge 271d so as not to stand out.

  In this embodiment, since the upper end of the connection piece 280a extends to the support plate 270a of the cover member 202, the connection piece 280a may be cut along the inner surface of the support plate 270a. Since 280a is connected not only to the inner surface of the support plate 270a but also to the guide piece 282, it is not cut only by cutting along the inner surface of the support plate 270a. Therefore, in order to cut the connection piece 280a, it corresponds to the gap S1. It is necessary to cut at the part to be.

  Here, as shown by the dotted line in FIG. 13C, the upper and lower ends of the fitting convex portion 281 and the fitting concave portion 266 are transparent through the connecting piece 280a made of a synthetic resin material having translucency. Therefore, for example, when the upper and lower ends of the fitting convex portion 281 and the fitting concave portion 266 are formed along the edge 282a and the edge 271d, the edge 282a and the edge 271d are aligned as described above. When the cutting groove 290a is formed by cutting, the upper and lower ends of the fitting convex portion 281 and the fitting concave portion 266 appear to overlap with the rear side of the cutting groove 290a, so that the cutting groove 290a becomes less conspicuous. .

  Therefore, as shown by the dotted line in FIG. 13C, the fitting convex portion 281 and the fitting concave portion 266 are formed so as to straddle the welding plate portion 271 and the guide piece 282, and thus along the edge 282a and the edge 271d. When the cutting groove 290a is formed by cutting the cutting groove 290a, the cutting groove 290a is formed at a position shifted in the vertical direction with respect to the upper and lower ends of the fitting convex portion 281 and the fitting concave portion 266, and on the rear side of the cutting groove 290a. Since the upper and lower sides of the fitting convex portion 281 and the fitting concave portion 266 do not appear to overlap each other, it is easy to discover that the cutting groove 290a is formed, that is, there is a possibility that the fitting groove 290a has been illegally cut.

  In the present embodiment, the fitting convex portion 281 is formed to extend from the connecting piece 280a to the welding plate portion 271 of the cover side welding portion 223 and the guide piece 282 of the cover member 202. It is not limited to this, and it may be formed so as to straddle at least one of the welding plate portion 271 and the guide piece 282 from the connecting piece 280a.

  Further, the opposing surfaces 269 and 283 have flat surfaces 269b and 283b parallel to the sliding movement direction of the cover member 202, and the fitting convex portion 281 protrudes from the flat surfaces 269b and 283b. When the joint convex portion 281 is cut, a trace of cutting becomes conspicuous.

  Further, the connecting pieces 280b and 280d are accommodated in the accommodating recess 268 when the cover-side welded portion 223 is accommodated in the accommodating recess 268. By doing so, unless the receiving recess 268 is destroyed, the cutter CT or the like cannot be inserted into the receiving recess 268 and the connecting pieces 280b and 280d cannot be cut.

  Next, Modifications 1 to 3 of the present invention will be described with reference to FIGS. 16A is a perspective view illustrating a state where the base-side welded portion and the cover-side welded portion as the first modification are viewed from the back side, and FIG. 16B is a perspective view illustrating the state viewed from the front side. is there. 17A is a front view showing a state in which the base-side welded portion and the cover-side welded portion are welded, FIG. 17B is a cross-sectional view taken along the line H-H in FIG. 17A, and FIG.

  In the following description, the same components as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  First, Modification 1 will be described with reference to FIGS. In the above embodiment, the fitting concave portion 266 is formed in the connecting piece 265a on the base member 201 side, and the fitting convex portion 281 is formed on the connecting piece 280a on the cover member 202 side, but the present invention is limited to this. Instead, as in the first modification, a fitting convex portion 300 is formed on a part of the facing surface 301 of the connecting piece 265a on the base member 201 side, and the facing surface 303 of the connecting piece 280a on the cover member 202 side. The fitting recessed part 302 may be formed in the.

  That is, as shown in FIG. 19, in the first modification, the facing surface 301 of the connecting piece 265 a that is the connecting corresponding portion is from a virtual straight line L <b> 3 that connects two points P <b> 21 and P <b> 22 on the flat surface 303 c of the facing surface 301. It has the fitting convex part 300 which is a convex part which protrudes in the connection piece 280a side. Specifically, the facing surface 301 is an outer surface of the fitting convex portion 300, and a sealing-side contact surface that comes into contact with the cover member 202 when the cover member 202 is slid to the second position in order to obtain a sealed state. 301a, a seal release side contact surface 301b that comes into contact with the cover member 202 when the cover member 202 is slid to the first position to release the sealed state, and the fitting convex portion 300. And a flat surface 301c.

  On the other hand, the facing surface 303 of the connecting piece 280a as the connecting portion is composed of inner surfaces 303a and 303b of the fitting recess 302 and a flat surface 303c formed around the fitting recess 302. In other words, the facing surface 303 has a fitting recess 302 that is a recess that is recessed in a direction away from the connecting piece 265a from a virtual straight line L4 connecting the two points P31 and P32 at the corners of the facing surface 303.

  Moreover, in the said Example, although the fitting recessed part 266 was described as an example of the to-be-fitted part, this invention is not limited to this, The to-be-fitted part which a fitting part can fit is provided. If so, it may be a hole or the like.

  Further, as shown in FIGS. 17C and 17D, the fitting convex portion 300 has a sealing-side contact surface 301a that comes into contact with the cover member 202 when the cover member 202 is slid to the second position. The sealing-side contact surface 301a is inclined rearward in the slide movement direction (left side). By doing so, when the cover member 202 is moved to the second position, the cover member 202 comes into contact with the sealing-side contact surface 301a and can easily get on, so that the cover member 202 can be smoothly moved to the second position. .

  Further, the fitting convex portion 300 has a seal release side contact surface 301b that comes into contact with the cover member 202 when the cover member 202 is slid to the first position, and the seal release side contact surface 301b is slid. It is substantially orthogonal to the moving direction (left-right direction). By doing in this way, when the cover member 202 is moved from the second position to the first position, the connection piece 280a of the cover member 202 comes into contact with the sealing release side contact surface 301b, so that the movement is restricted. It is possible to make it difficult to release the first sealing state.

  As shown in FIG. 18, when cutting the connecting piece 280a, the cutter CT is arranged along the sliding movement direction of the cover member 202 from the back surface of the connecting piece 280a to the connecting piece 280a, and the cutter CT is moved toward the front side. While reciprocating left and right, cut and cut. Then, as shown in FIGS. 18A and 18B, when the blade CTA of the cutter CT reaches the flat surface 303c of the opposing surface 303, it cuts to the fitting convex portion 300 of the other connecting piece 265a.

  As described above, since the facing surface 303 of the connecting piece 280a and the facing surface 301 of the connecting piece 265a are non-flat surfaces having convex portions and concave portions in part, the connecting piece 280a is not damaged so as not to damage the connecting piece 265a. In order to cut, it is necessary to cut the blade CTA of the cutter CT along the facing surface 303. However, when the fitting convex portion 300 is fitted in the fitting concave portion 302, it is more difficult to move and cut the blade CTA along the facing surface 301 than to cut the flat facing surface. Since the facing surfaces 303 and 301 are disposed close to each other, if the blade CTA of the cutter CT protrudes from the facing surface 303 even a little, the facing surface 301 is damaged, so that traces of cutting tend to remain.

  Further, the facing surface 301 has a sealing side contact surface 301a that contacts the connecting piece 280a of the cover member when the cover member 202 is slid to the second position, and the sealing side contact surface 301a is in the sliding movement direction. It is inclined up and down. By doing in this way, it becomes easy to slide the cover member 202 to the 2nd position side.

  Further, the facing surface 301 has a seal release side contact surface 301b that contacts the connecting piece 280a of the cover member when the cover member 202 is slid to the second position, and the seal release side contact surface 301b is slid It is substantially orthogonal to the moving direction. By doing in this way, since it becomes difficult to slide the cover member 202 to the 1st position side, it can be made difficult to cancel | release a 1st sealing state.

  Next, a second modification of the present invention will be described based on FIGS. In the embodiment, as an example of the connecting portion, the connecting pieces 280a to 280d that connect the cover side welded portion 223 and the main body of the cover member 202 are the upper and lower support plates on the main body side of the cover member 202. Although connected to 270a and 270b, that is, connected in a direction substantially orthogonal to the sliding movement direction of the cover member 202, the present invention is not limited to this, and the sliding movement of the cover member 202 is performed. It may be connected in the direction.

  Specifically, an insertion piece 310 projects from the right side surface of the welding plate portion 261 of the base side welding portion 207. Further, the cover-side welded portion 223 and the side wall 202d are connected by a connecting cylinder 320 as a connecting portion in which an insertion hole 321 facing the left-right direction in which the insertion piece 310 can be inserted is formed. The insertion hole 321 is opened on the left side so that the insertion piece 310 can be inserted, and the right side is closed.

  As shown in FIG. 22, the connecting cylinder 320 as the connecting portion is formed in a square cylinder shape, and the insertion hole 321 is also formed in a substantially square shape in cross section, so that the opposing surfaces 322 of the connecting cylinder 320 are connected to each other. The four flat surfaces 322a to 322d are formed in a square frame shape. In this case, the facing surface 322 has, for example, a substantially triangular recess recessed in a direction away from the insertion piece 310 from a virtual straight line L5 connecting two arbitrary points P41 and P42 (for example, facing corners) on the facing surface 322. Two are provided on both sides of the virtual straight line L5.

  On the other hand, the insertion piece 310 is formed in a substantially quadrangular prism shape in sectional view, and the opposing surface 311 of the insertion piece 310 is configured by a plurality of flat surfaces 311a to 311d that are connected to each other and formed in a rectangular frame shape. In this case, the opposing surface 311 is, for example, a substantially triangular convex portion that protrudes toward the connecting cylinder 320 from a virtual straight line L6 that connects two arbitrary points P51 and P52 (for example, opposing corners) on the opposing surface 311. Two are provided on both sides of the virtual straight line L6.

  Here, as shown in FIG. 21A, when cutting the connecting cylinder 320 as the connecting portion, a direction substantially orthogonal to the sliding movement direction of the cover member 202 from the back surface of the connecting cylinder 320 to the connecting cylinder 320. The cutter CT is arranged on the front, and the cutter CT is reciprocated up and down toward the front while cutting and cutting. In this case, as shown in FIG. 21 (B), the connecting cylinder 320 covers the periphery of the insertion piece 310. Therefore, when the cutter CT is cut forward, the insertion piece 310 is cut. End up.

  As described above, the facing surface 322 of the connecting tube 320 and the facing surface 311 of the insertion piece 310 are non-planar surfaces having convex portions and concave portions in part, so that the connecting tube 320 is not damaged. In order to cut, it is necessary to cut the blade CTA of the cutter CT along the facing surface 322, that is, cut from four sides along the flat surfaces 322a to 322d. Therefore, it is more difficult than cutting the flat opposing surface, and the opposing surfaces 322 and 311 are arranged close to each other, so that the blade CTA of the cutter CT can protrude from the opposing surface 322 even a little. In this case, since the facing surface 311 is damaged, a trace of cutting tends to remain.

  In addition, the trace of the cutting | disconnection formed in the insertion piece 310 can be visually recognized through this connection cylinder 320 because the connection cylinder 320 is formed of the permeable member. Further, the insertion piece 310 and the insertion hole 321 may not be rectangular in sectional view, may be substantially circular in sectional view, and can be variously changed.

  Moreover, in the said Example and modification, in the state in which the cover member 202 was located in the 2nd position, the opposing surface 283 of the connection pieces 280a, 280b, 280d which is a connection part is connection piece 265a-265c as a connection corresponding | compatible part. However, the present invention is not limited to this, and may be in contact with each other.

  Moreover, in the said Example and modification, the fitting convex parts 281 and 300 were formed in a part of opposing surface 283,301, and the fitting recessed parts 266 and 302 were formed in a part of opposing surface 269,303. However, this invention is not limited to this, The whole region of the opposing surface of a connection part may be formed as a fitting convex part. Moreover, the some convex part may be formed in the opposing surface of a connection part, and in such a case, an opposing surface will be formed in uneven | corrugated shape.

  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. In other words, the facing surface is not formed by a single flat surface, but may be formed by a plurality of flat surfaces or curved surfaces. 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. Furthermore, like the modification 2, it may be provided so that one opposing surface of a connection part and a connection corresponding | compatible part may cover all the other opposing surfaces.

  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.
