Description

  The present invention relates to a gaming machine in which a game effect is performed in a plurality of effect modes.

  Conventionally, a pachinko machine, which is a kind of gaming machine, includes a variable display of a liquid crystal display type, for example, and a symbol combination game for deriving a symbol combination by varying a plurality of types of symbols on the variable display has been performed. . Then, the player can recognize the big hit or miss from the symbol combination derived in the symbol combination game and finally stopped and displayed.

  In such a pachinko machine, for example, various effects such as a reach effect and a notice effect are performed in order to enhance the interest of the game. The reach effect is an effect that is performed after the reach is formed (reach combination is displayed) in the symbol combination game, until the jackpot combination or the combination of losing is stopped or temporarily stopped. In addition, the notice effect is an effect in which a specific character or the like appears on the variable display device during the symbol combination game and notifies in advance that there is a high possibility of being a big hit. In the pachinko machine, a plurality of types of reach effects and notice effects are prepared, and the player's expectation for the big hit is changed. In other words, these effects are effects that have a high rate of appearance (appearance rate) as an effect in the symbol combination game but have a low expectation of being a big hit, or effects that have a low rate of appearance (appearance rate) but have a high expectation of being a big hit. The expectation that becomes a big hit of the player is changed according to the size of the expectation.

By the way, even if many kinds of effects are prepared as described above, the player cannot always see all the effects but can only see a part of the effects. In particular, the player sees the production having the highest occurrence rate and the low expectation of being a big hit, and the production having the low occurrence rate and the high expectation of a big hit is less likely to see. Therefore, if a player plays a game several times with the same or the same type of pachinko machine, the player will grasp the characteristics of the production (the appearance rate of the production and the degree of expectation for the jackpot), and the Depending on the type, you can not have a sense of expectation for the big hit, lack of interest and get bored. Therefore, conventionally, a pachinko machine has been proposed that can change the rate at which the effects appear and the expectation level of the effects based on a predetermined opportunity (see Patent Document 1 and Patent Document 2). In the pachinko machines of Patent Documents 1 and 2, a special mode with different appearance ratio and expectation is prepared, and the mode is selected at the time of power-on or when winning for the first time after power-on. Depending on the situation, the rate of occurrence and the degree of expectation are varied. In the pachinko machines of Patent Documents 1 and 2, it is said that the player can enjoy a variety of games without the player's rate and expectation of appearance appearing fixedly.
JP 11-319235 A (paragraph numbers [0053] to [0055], FIG. 14) Japanese Patent Laid-Open No. 10-15175 (paragraph numbers [0167], [0168])

  However, the pachinko machines disclosed in Patent Documents 1 and 2 have the following problems. That is, in the pachinko machines disclosed in Patent Documents 1 and 2, when a prize is won for the first time after power-on or after power-on, a random number lottery is performed inside the machine, and a special mode is selected based on the lottery result.

  For this reason, it has been difficult for amusement stores to set the proportion of pachinko machines that have selected a special mode in an island where a plurality of pachinko machines are installed. That is, when the mode is set when the power is turned on, if the power is turned on during business hours due to a failure of the pachinko machine, the mode set at the time of opening the store is changed. In addition, when the mode is set when winning for the first time after the power is turned on, the mode is changed by the player's operation. Therefore, for example, the amusement store side cannot intentionally increase the proportion of pachinko machines in which a special mode in which the player is interested, such as a mode in which premium effects are likely to appear, is set.

  The present invention has been made paying attention to such problems existing in the prior art, and its purpose is that only the amusement store side can select a special effect mode from a plurality of effect modes according to the intention of the amusement shop side.

In a gaming machine having a plurality of production modes consisting of production modes, the front frame is opened, the middle frame is opened, the dish member is opened, or the locking means is unlocked. Detect at least one of To a detection means, a measurement means for measuring the number of outputs of a detection signal indicating that the detection means has detected, a determination means for determining whether or not the number of outputs has reached a predetermined number of 2 or more, and a gaming machine When the determination result of the determination means becomes affirmative during a predetermined selection period from when the power is turned on, selection means for selecting the special effect mode is provided.

  The invention according to claim 2 is the invention according to claim 1, further comprising display means for performing a symbol variation game for variably displaying a plurality of types of symbols, wherein the selection period is the first symbol from the time of power-on. The gist is that it is a period until a variable game is played.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, there are a plurality of types of the special effect mode, and the selection unit is responsive to the number of detection signals output by the measurement unit. The gist is to select one special effect mode from a plurality of special effect modes.

  A fourth aspect of the present invention is the invention according to any one of the first to third aspects, further comprising a notifying means for notifying a type of the effect mode selected by the selecting means. And

  According to a fifth aspect of the present invention, in the invention according to any one of the first to fourth aspects, the detection means is a position on the front side of the middle frame, and the front frame is closed. The gist is to detect the opening of the front frame by being arranged at a position covered by the front frame when being done.

  According to the present invention, only the game shop side can set the special effect mode from the plurality of effect modes by the intention of the game shop side.

Hereinafter, an embodiment in which the present invention is embodied in a pachinko gaming machine (hereinafter referred to as a “pachinko machine”) that is a kind of the present invention will be described with reference to FIGS.
In FIG. 1, the front side of the pachinko machine 10 is schematically shown, and a vertical rectangular middle frame 12 for setting various game components is opened and closed on the front side of the opening of the outer frame 11 that forms the outline of the machine body.

In addition, on the front side of the middle frame 12, a vertical rectangular front frame 14 having a glass frame on which a protective glass 27 for see-through protection of the game board 13 disposed inside the machine is mounted can be opened and closed in a horizontally opened state. It is assembled. In FIG. 2, a state in which the front frame 14 is opened is illustrated. As shown in FIGS. 1 and 2, the horizontal width of the middle frame 12 (the width in the horizontal direction in the figure) and the horizontal width of the front frame 14 are the same, and the vertical width of the middle frame 12 (the vertical width in the figure) is the front frame. It is formed longer than the vertical width of 14.

  Further, on the lower side of the front frame 14 and on the front side of the middle frame 12, there is an upper ball tray 15 as a dish member for storing game balls to be supplied to the launching device 19 provided in the lower portion of the middle frame 12. It is assembled so that it can be opened and closed in a horizontally open state. These middle frame 12, front frame 14 and upper ball tray 15 are provided with locks 28 as locking means so that they cannot be opened unless the locks 28 are unlocked with a predetermined key. . This predetermined key is normally managed only by the amusement shop side to prevent fraud. Therefore, the middle frame 12, the front frame 14, and the upper ball tray 15 can be opened only by a game store. Further, an opening sensor 29 is provided on the front side of the middle frame 12 as detection means for detecting the opening of the front frame 14. As shown in FIG. 2, the open sensor 29 is located on the front side of the middle frame 12 and is covered by the front frame 14 when the front frame 14 is closed (in FIG. 2, the pachinko machine 10 Is located in the upper right). When the front frame 14 is opened (see FIG. 2), the open sensor 29 outputs an open signal indicating that the front frame 14 is opened to the main control board 30 (main CPU 30a).

  In addition, a frame lamp 16 a is provided on the front side of the front frame 14, and a game board lamp 16 b is provided in the game area 13 a of the game board 13. The frame lamp 16a and the game board lamp 16b are turned on (flashing) or turned off to perform a light emission effect based on the light emission decoration. In addition, a speaker 17 that outputs various sounds (sound effects) and performs sound effects based on the sound output is provided below the outer frame 11. A lower ball tray 18 and a launching device 19 are attached to the lower part of the middle frame 12.

  In the approximate center of the game area 13a of the game board 13, a display device 21 having a liquid crystal display type variable display H is provided. In the display device 21, a game effect (display effect) based on a variable image (or image display) of the variable display H is performed. In the variable display H, a symbol combination game (symbol changing game) for deriving a symbol combination by varying a plurality of types of symbols in a plurality of columns is performed in association with the display effect. In the present embodiment, a combination of three columns of symbols is derived in the symbol combination game, and eight types of symbols of 0, 1, 2, 3, 4, 5, 6, and 7 constituting each combination are derived. It is a number. Therefore, in this embodiment, the variable display H becomes a display means for performing the symbol combination game.

  Then, the player can recognize the big hit or miss from the symbol combination finally displayed on the variable display H. When the symbols of all the columns displayed on the variable display H are of the same type, the big hit can be recognized from the symbol combination ([111] [777] or the like). The symbol combination that can recognize the jackpot is a jackpot combination. When the jackpot combination is finally (deterministic) displayed, the player is given a jackpot gaming state. Further, when the symbols of all the columns displayed on the variable display H are of different types, it is possible to recognize the deviation from the symbol combination ([234] [122] [767], etc.). A combination of symbols that can recognize this deviation is a combination of deviations.

  Also, below the display device 21, a start winning opening 23 including an opening / closing blade 22 that opens and closes by an operation of an actuator (solenoid, motor, etc.) (not shown) is disposed. Behind the start winning opening 23, a start opening sensor SE1 (shown in FIG. 3) for detecting a winning game ball is provided. The start winning opening 23 can give a start condition for the symbol combination game in response to detection of winning of a game ball.

  Also, below the start winning opening 23, a large winning opening 24 provided with a large winning opening door 26 that opens and closes by the operation of an actuator (solenoid, motor, etc.) (not shown) is disposed. The big winning opening 24 is derived by the symbol combination game, and the big winning opening door 26 opens and closes in association with the symbol combination finally displayed being a big hit combination so that it is opened or closed. It has become. When the big hit gaming state is given, the big winning opening 24 is opened by the opening / closing operation of the big winning opening door 26 so that the game ball can be won, so that the player has a chance to acquire a large number of winning balls. Obtainable.

Next, the control configuration of the pachinko machine 10 will be described with reference to FIG.
A main control board 30 that controls the entire pachinko machine 10 is mounted on the back side of the pachinko machine 10. The main control board 30 executes various processes for controlling the entire pachinko machine 10, performs arithmetic processing on various control signals (control commands) for controlling the game according to the processing results, and outputs the control signals ( Control command). In addition, an overall control board 31, a display control board 32, a lamp control board 33, and a sound control board 34 are mounted on the rear side of the machine. The overall control board 31 comprehensively controls the display control board 32, the lamp control board 33, and the sound control board 34 based on the control signal (control command) output from the main control board 30. The display control board 32 is based on the control signal (control command) output from the main control board 30 and the overall control board 31 and the display mode of the display device 21 (variable display H) (display images such as symbols, backgrounds, characters, etc.) ) To control. The lamp control board 33 changes the light emission mode (lighting (flashing) / lighting timing, etc.) of the frame lamp 16a and the game board lamp 16b based on control signals (control commands) output from the main control board 30 and the overall control board 31. Control. The sound control board 34 controls the sound output mode (sound output timing, etc.) of the speaker 17 based on the control signal (control command) output from the main control board 30 and the overall control board 31.

  Accordingly, in the present embodiment, the main control board 30 is a main control device that controls the entire pachinko machine 10. In addition, the overall control board 31 of this embodiment is a sub-control device that executes various controls according to the control signal output by the main control board 30.

Hereinafter, specific configurations of the main control board 30, the overall control board 31, and the display control board 32 will be described.
The main control board 30 is provided with a main CPU 30a. A ROM 30b and a RAM 30c are connected to the main CPU 30a. An open sensor 29 is connected to the main CPU 30a. Since the main CPU 30a inputs an opening signal from the opening sensor 29 while the front frame 14 is opened, the main CPU 30a can detect that the front frame 14 is opened. Further, the main CPU 30a is configured to sequentially update various random number values at predetermined intervals.

  The ROM 30b stores a main control program for controlling the pachinko machine 10 and a plurality of types of effect patterns. The RAM 30c stores various information (such as various random values) that can be appropriately rewritten during the operation of the pachinko machine 10.

  The effect pattern indicates a pattern that is a base of the effect performed by the pachinko machine 10. In the ROM 30b, a plurality of types of effect patterns are classified and stored for the jackpot effect and for the off-stage effect. The jackpot effect is an effect in which the symbol combination game is developed so as to display the jackpot combination. The outlier effect is an effect in which the symbol combination game is developed so as to display a combination of outliers. In the present embodiment, the effect pattern for the jackpot effect is indicated as “effect pattern P1”, and the effect pattern for the off-line effect is indicated as “effect pattern P2”.

  The main CPU 30a executes various processes such as jackpot determination, determination of the final stop symbol to be finally displayed, and determination of the effect pattern based on the main control program. For example, the main CPU 30a executes a big hit determination at the start of the symbol combination game. When the determination result of the big hit determination is affirmative (in the case of a big hit), the main CPU 30a determines the final stop symbols so that all the columns are of the same type, and also determines the effect pattern P1. On the other hand, when the determination result of the big hit determination is negative (in the case of losing), the main CPU 30a determines the final stop symbol of each column and the effect pattern P2 so that the symbols of all the columns are not of the same type.

  The main CPU 30a, which has determined the effect pattern and the final stop symbol, outputs a predetermined control command to the overall control board 31 (overall CPU 31a) at a predetermined timing. Specifically, the main CPU 30a first designates an effect pattern and outputs an effect pattern designation command for instructing the start of symbol variation. Next, the main CPU 30a outputs a symbol designation command for designating a final stop symbol for each column. After that, the main CPU 30a instructs a change stop based on the change time set in the designated effect pattern, and outputs an all symbol stop command for ending the symbol combination game.

Next, the overall control board 31 will be described.
As shown in FIG. 3, the overall control board 31 is provided with an overall CPU 31a. The general CPU 31a sequentially updates the values of various random numbers every predetermined cycle. Further, a ROM 31b and a RAM 31c are connected to the overall CPU 31a. The ROM 31b stores a control program for comprehensively controlling the control boards 32-34. The RAM 31c stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10. For example, information such as the value of the mode flag and the notice pattern distribution random number is stored (set) in the RAM 31c.

  When a predetermined control command is input from the main CPU 30a at a predetermined timing, the overall CPU 31a outputs a predetermined control command at a predetermined timing accordingly. More specifically, when the overall CPU 31a inputs an effect pattern designation command, the overall CPU 31a outputs the effect pattern designation command to each of the control boards 32-34. In addition, when the overall CPU 31 a inputs a symbol designation command or an all symbol stop command, the overall CPU 31 a outputs each command to the display control board 32.

  Further, the pachinko machine 10 of the present embodiment is configured such that a big hit notice is performed in a display effect during the symbol combination game, and whether or not the general control board 31 (the general CPU 31a) executes the big hit notice. It comes to decide. The jackpot notice is an effect (an effect that suggests the possibility of success or failure) for informing the player in advance that there is a possibility of a big hit. In the present embodiment, the notice character Ka or the notice character Kb is made to appear (display) on the variable display H so as to make a jackpot notice, and two types of effect contents of the jackpot notice are prepared. Hereinafter, when the jackpot notice in which the notice character Ka and the notice character Kb appear is distinguished and described, the jackpot notice in which the notice character Ka appears is referred to as “hit notice YKa”, and the jackpot notice in which the notice character Kb appears is “ It is indicated as “Large hit notice YKb”.

  When the general CPU 31a inputs an effect pattern designation command, the notice pattern assignment random number and the notice pattern assignment table Y1 (FIG. 4 (a)) stored in the ROM 31b and the notice pattern assignment table Y2 (FIG. 4 (b)). ) Or the notice pattern allocation table Y3 (FIG. 4C) is executed. In the notice determination process, the overall CPU 31a determines whether or not to execute the jackpot notice, and determines the effect of the jackpot notice when the jackpot notice is executed. The notice pattern distribution random number is a random number that is sequentially updated by the overall CPU 31a every predetermined period, and the overall CPU 31a sets the updated value in the setting area of the RAM 31c and rewrites the value before the update. In the present embodiment, the numerical values that can be taken by the notice pattern distribution random numbers are 50 different integers from 0 to 49.

  In addition, the pachinko machine 10 according to the present embodiment is provided with a plurality of (three types in the present embodiment) presentation modes that allow a game presentation to be performed in different presentation modes. In the present embodiment, an effect mode 1 as a normal effect mode, an effect mode 2 and an effect mode 3 as special effect modes are provided. The effect mode may shift to another effect mode after a predetermined selection period has elapsed, that is, when the symbol combination game is executed a plurality of times. In addition, when the predetermined variation pattern is selected, the event mode transitions when the symbol combination game displayed in the symbol combination game, the random combination lottery performed for each symbol combination game, For example, it is executed a predetermined number of times. The special performance mode is less likely to shift than the normal performance mode. That is, the probability of shifting from the normal effect mode to the special effect mode is set lower than the probability of shifting from the special effect mode to the normal effect mode.

  The contents of the production mode will be specifically described. In the effect mode 1, the effect mode 2 and the effect mode 3, the appearance rates of the jackpot notice YKa and the jackpot notice YKb (indicating the rate at which the jackpot notice is performed) are different.

  More specifically, in the effect mode 1, the big hit notice YKa is performed in any of the symbol combination games that are not the symbol combination game that is the big hit effect. On the other hand, in the effect mode 1, the jackpot notice YKb is not performed in any of the symbol combination games that are out of the symbol combination game that is the jackpot effect. That is, in the production mode 1, the appearance rate of the jackpot notice YKb is 0%.

  In the effect mode 2, the symbol combination game in which the jackpot notice YKb is a jackpot effect is only performed in any of the symbol combination games in which the jackpot notice YKa is a jackpot effect. To be done. In other words, in the production mode 2, the appearance rate of the jackpot notice YKb in the case of the offense effect is 0%, whereas the appearance rate of the jackpot notice YKb in the case of the jackpot effect is not 0%. Therefore, in the effect mode 2, the appearance rate of the jackpot notice (the jackpot notice YKa and the jackpot notice YKb) is different from the effect mode 1.

  In the effect mode 3, the jackpot notice YKa and the jackpot notice YKb are played in any of the symbol combination games that are different from the symbol combination game that is the jackpot effect. That is, in the production mode 3, the appearance rate of the jackpot notice YKb is not 0%. For this reason, in the effect mode 3, the appearance rate of the jackpot notice (the jackpot notice YKa and the jackpot notice YKb) is different from the effect mode 1. Moreover, in the production mode 3, the appearance rate of the jackpot notice YKb in the case of a loss production is not 0%. For this reason, in the effect mode 3, the appearance rate of the jackpot notice (the jackpot notice YKa and the jackpot notice YKb) is different from the effect mode 2.

  As described above, the appearance rate of the jackpot notice is changed depending on the production mode. And in the production mode 2 and the production mode 3 which are special production modes, the big hit notice YKb which is not performed in the production mode 1 which is a normal production mode is performed. For this reason, it can be said that the special effect mode is an effect mode that improves the interest of the player than the normal effect mode. Also, in the effect mode 2, the jackpot notice YKb is performed only in the symbol combination game that is a big hit, so the jackpot notice YKb in the effect mode 2 is an effect that enhances the player's expectation more than the jackpot notice YKb in the effect mode 3. It can be said.

  In the present embodiment, as described above, in order to vary the appearance rate of the jackpot notice in effect mode 1 to effect mode 3, three types of notice pattern distribution tables Y1, Y2, and Y3 are stored in the ROM 31b. (FIG. 4). The notice pattern distribution table Y1 is a table that the overall CPU 31a refers to in the notice determination process in the case of the effect mode 1, and the notice pattern distribution table Y2 is a table that is referred to in the effect mode 2, and the notice pattern The distribution table Y3 is a table referred to in the case of the production mode 3. Hereinafter, specific configurations of the notice pattern distribution table Y1, the notice pattern distribution table Y2, and the notice pattern distribution table Y3 will be described with reference to FIG.

  In the notice pattern allocation table Y1, Y2, Y3, “no notice”, “notice pattern YA”, or “notice pattern YB” is selected according to the designated production pattern P1, P2 based on the value of the notice pattern assignment random number. Either one is determined. The overall CPU 31a determines not to execute the jackpot notice by determining “no notice”, and determines to execute the jackpot notice by determining “notice pattern YA” or “notice pattern YB”. Further, the overall CPU 31a determines the contents of the effect of the big hit notification by determining either “notice pattern YA” or “notice pattern YB”. The notice pattern YA is a pattern in which the effect content of the jackpot notice YKa is specified, and the notice pattern YB is a pattern in which the effect content of the jackpot notice YKb is specified.

  In the notice pattern distribution table Y1, the effect pattern P1 for the big hit effect includes the values “0” to “19” of the notice pattern distribution random numbers in “No notice” and the notice pattern distribution random numbers in “Notice pattern YA”. Values “20” to “49” are associated with each other. In the effect pattern P2 for the big hit effect, the values “0” to “39” of the notice pattern distribution random numbers are set to “no notice”, and the values “40” to “49” of the notice pattern assignment random numbers are set to “the notice pattern YA”. "Is associated. Therefore, in the case of the production mode 1, the general CPU 31a determines whether there is “no notice” or “the notice pattern YA” in the notice determination process, regardless of which of the effect pattern P1 or the effect pattern P2. It has become.

  On the other hand, in the notice pattern distribution table Y2, the effect pattern P1 for the big hit effect includes the values “0” to “9” of the notice pattern distribution random numbers for “no notice” and the notice pattern distribution for the “notice pattern YA”. The random number values “10” to “39” are associated with the “notice pattern YB” and the random number values “40” to “49” of the notice pattern distribution. That is, unlike the notice pattern distribution table Y1, in the effect pattern P1 of the notice pattern distribution table Y2, “notice pattern YB” is associated with the value of the notice pattern distribution random number. In the notice pattern distribution table Y2, for the effect pattern P2, the correspondence of the value of the notice pattern distribution random number is the same as that in the notice pattern distribution table Y1. Therefore, in the case of the production mode 2, the general CPU 31a may determine the notice pattern YB when the production pattern P1 for the big hit production is designated. As a result, in the effect mode 2, unlike the effect mode 1, the jackpot notice YKb may appear in the symbol combination game (the symbol combination game based on the effect pattern P1) that becomes the jackpot effect.

  In the notice pattern distribution table Y3, the effect pattern P1 for the big hit effect includes the values “0” to “9” of the notice pattern distribution random numbers for “no notice” and the notice pattern distribution for the “notice pattern YA”. The random number values “10” to “39” are associated with the “notice pattern YB” and the random number values “40” to “49” of the notice pattern distribution. In addition, in the notice pattern allocation table Y3, the effect pattern P2 for the off effect is “no notice” and the random numbers “0” to “29” of the notice pattern assignment random numbers, and the notice pattern assignment to the “notice pattern YA”. The random number values “30” to “44” are associated with the “notice pattern YB” and the random number values “45” to “49” of the notice pattern distribution.

  That is, in the advance notice pattern distribution table Y3, unlike the advance notice pattern assignment table Y1, the “notice pattern YB” and the value of the advance notice pattern assignment random number are associated with each other. Therefore, in the case of the effect mode 3, the general CPU 31a may determine the notice pattern YB when the effect pattern P1 or the effect pattern P2 is designated. As a result, in the effect mode 3, unlike the effect mode 1, a big hit notice YKb may appear in the symbol combination game. Also, unlike the notice pattern distribution table Y2, in the effect pattern P2 of the notice pattern distribution table Y3, “notice pattern YB” and the value of the notice pattern distribution random number are associated with each other. Therefore, in the case of the effect mode 3, the general CPU 31a may determine the notice pattern YB when the effect pattern P2 for the off effect is designated. As a result, in the effect mode 3, unlike the effect mode 2, the jackpot notice YKb may appear in the symbol combination game (the symbol combination game based on the effect pattern P2) that is an outlier effect.

  Preliminary pattern sorting tables Y1 to Y3 having such a configuration are stored in the ROM 31b, and when the general CPU 31a inputs the production pattern designation command, the value of the preliminary announcement pattern distribution random number is extracted from the RAM 31c, and the production mode is the production mode. In the case of 1, the notice determination process is performed based on the notice pattern distribution table Y1. In addition, when the production pattern designation command is input, the general CPU 31a performs a notice determination process based on the notice pattern distribution table Y2 in the case of the effect mode 2, and in the notice pattern distribution table Y3 in the case of the effect mode 3. Based on the previous notice determination process. When the general CPU 31a determines the notice pattern YA or the notice pattern YB based on the result of the notice determination process, the general CPU 31a outputs a notice pattern designation command for designating the notice pattern together with the effect pattern designation command to the display control board 32 (sub CPU 32a). To do.

Next, the display control board 32 will be described.
The display control board 32 includes a sub CPU 32a, and a ROM 32b and a RAM 32c are connected to the sub CPU 32a. The ROM 32b stores a display control program and various image data (image data such as symbols, backgrounds, characters, characters, etc.) for controlling the display contents of the variable display device H (variations of symbols and actions of characters). Yes. The RAM 32c stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  When the sub CPU 32a receives a control command from the overall control board 31 (overall CPU 31a), the sub CPU 32a performs control according to the input control command based on the display control program. Specifically, when the sub CPU 32a inputs an effect pattern designation command, the display contents of the variable display H are displayed so as to start the symbol combination game by variably displaying the symbols in the effect pattern designated by the effect pattern designation command. To control. Then, when the sub CPU 32a inputs all symbol stop commands, the variable display H displays the symbol combinations of the stop special symbol left, the stop special symbol, and the stop special symbol specified by the input special symbol designation command. Thus, the display content of the variable display H is controlled. By this control, the symbol combination game is performed on the variable display H. In addition, when the sub CPU 32a inputs the notice pattern designation command, the variable display H to display the big hit notice (hit notice YKa or big hit notice YKb) with the notice pattern designated by the notice pattern designation command together with the symbol combination game. Controls the display content of.

  Then, the general CPU 31a of the present embodiment selects any one of the production mode 1 to the production mode 3 and sets the selected production mode during the period from when the power is turned on until the first symbol combination game is started. It has become. More specifically, if the front frame 14 is opened and closed several times during the period from when the power is turned on until the first symbol combination game is started, the general CPU 31a selects the production mode 2 or the production mode 3. In other cases, the production mode 1 is selected.

Hereinafter, various processes executed when the main CPU 30a and the overall CPU 31a select the effect mode will be described.
When the open signal is input from the open sensor 29, the main CPU 30a determines whether or not 0 is set in the set period flag. The setting period flag is a flag indicating whether or not it is a selection period in which the effect mode can be set, and is set in the RAM 30c. When 0 is set in this setting period flag, it indicates that it is a selection period. The set period flag is set to 0 from when the pachinko machine 10 is turned on until the first presentation pattern designation command is output to the overall CPU 31a. That is, the selection period of the present embodiment is from when the power is turned on to when the first symbol combination game is started.

  When this determination result is affirmative (when the setting period flag is set to 0), the main CPU 30a adds 1 to the open / close count value indicating the open / close count of the front frame 14, and rewrites the open / close count value. Note that the open / close count value is stored in the RAM 30c, and is set to 0 (initial value) when the power is turned on.

  Next, the main CPU 30a determines whether or not the open / close count value has reached a predetermined value (10 times in the present embodiment). That is, the main CPU 30a determines whether the selectable condition is satisfied. If the determination result is affirmative, the main CPU 30a outputs a mode change signal that instructs the overall control board 31 (overall CPU 31a) to change the effect mode. Therefore, in the present embodiment, the main CPU 30a serves as a measurement unit that measures the number of times the release signal (detection signal) is output. Further, the main CPU 30a serves as a determination unit that determines whether or not the number of outputs of the release signal (detection signal) has reached a predetermined number.

  When the overall CPU 31a receives a mode change signal from the main CPU 30a, the overall CPU 31a sets the special effect mode as the effect mode. That is, the overall CPU 31a sets the production mode 2 or the production mode 3. Specifically, the overall CPU 31a determines one effect mode from the special effect modes by random number lottery. Then, the overall CPU 31a sets 1 or 2 to the mode flag indicating the rendering mode based on the random number lottery result, and stores it in the RAM 31c. The mode flag is a flag indicating the type of the effect mode. When 0 is set, the effect mode 1 is set. When 1 is set, the effect mode 2 is set. Indicates that the production mode 3 is set. When the power is turned on, 0 is set in the mode flag. Accordingly, in the present embodiment, the overall CPU 31a serves as a selection unit that selects the special effect mode.

  As described above, unless the selectable condition that the front frame 14 is opened and closed a plurality of times is satisfied, the special effect mode is not selected. Since the lock 28 must be unlocked to open the front frame 14, those who can satisfy the selection condition are those at the amusement store. Therefore, only the game store side can set the special performance mode. Also, the special effect mode is not set unless the selection period is from when the power is turned on until the first symbol combination game is started. The period from when the power is turned on until the first symbol combination game is started usually corresponds to the opening of the amusement store. Therefore, the special effect mode can be set only when the store is opened. And in order to open and close several times, a game store will open and close with the intention of changing the production mode. For this reason, even if the front frame 14 is opened and closed once for adjustment of the pachinko machine 10, it is possible to prevent the effect mode from changing.

  Next, the timing at which the effect mode is switched in the present embodiment will be described with reference to FIG. FIG. 5A shows a case where the front frame 14 is not opened and closed a predetermined number of times (10 times) from when the power is turned on until the first symbol combination game is started. FIG. 5B shows the case where the front frame 14 is opened and closed a plurality of times from when the power is turned on until the first symbol combination game is started.

  As shown in FIG. 5A, when the power is turned on (time point A1), the mode flag is set to 0, and the normal effect mode (effect mode 1) is set as the effect mode. At this time, 0 is set in the setting period flag. Here, even if the front frame 14 is released once after the power is turned on until the first symbol combination game is started (time point A2), the main CPU 30a does not output a mode change signal. Do not set the special performance mode. That is, even if the front frame 14 is opened and the gaming machine is adjusted (for example, setting of a nail) during the period from when the power is turned on until the first symbol combination game is started, the number of times the front frame 14 is opened and closed If it is less than or equal to the number of times, the special performance mode is not set.

  When the first symbol combination game is started (time point A3), the main CPU 30a sets 1 to the setting period flag. For this reason, after that, even if the front frame 14 is opened and closed a plurality of times, the effect mode cannot be set.

  Further, as shown in FIG. 5B, after the power is turned on (time B1) and the mode flag is set to 0, every time the front frame 14 is opened (time B2 to B10), the main control board 30 The (main CPU 30a) inputs an open signal from the open sensor 29 and adds 1 to the open / close count value. The main control board 30 (main CPU 30a) outputs a mode change signal to the general control board 31 (general CPU 31a) when the number of times of opening and closing after power-on reaches a predetermined value (10) (time point B11). .

  The general CPU 31a inputs the mode change signal to set the special effect mode (effect mode 2 or effect mode 3) as the effect mode. Here, description will be made assuming that the rendering mode 2 is set as the special rendering mode as a result of the random lottery. Therefore, the overall CPU 31a sets 1 to the mode flag.

  Thereafter, when the first symbol combination game is started (time B12), the overall CPU 31a sets 1 to the setting period flag. For this reason, after this, even if the front frame 14 is opened, the production mode cannot be set.

As described above in detail, the present embodiment has the following effects.
(1) When the opening and closing of the front frame 14 is repeated a predetermined number of times during the period from when the power to the pachinko machine 10 is turned on until the first symbol combination game is started, the general CPU 31a selects the special effect mode as the effect mode. And set. Since the front frame 14 can be opened only by the game store side, only the game store side can set the special effect mode. Moreover, since the simple condition of opening the front frame 14 is set as a selectable condition, the special effect mode can be easily set. In addition, since the special effect mode is not selected unless it is operated a plurality of times, for example, even if the power is turned off and the front frame 14 is opened and closed once due to a malfunction of the pachinko machine 10, the special effect mode is not selected. That is, since the special effect mode is not selected unless it is intentionally opened and closed a plurality of times, it is possible to prevent the special effect mode from being selected when the game shop side does not intend.

  (2) The period during which the special effect mode can be set is a period from when the power is turned on until the first symbol combination game is performed. For this reason, the special effect mode can be set only when the game shop side opens. That is, the front frame 14 may be opened during business operations due to a failure of the pachinko machine 10 (ball clogging or the like), but the selectable condition is not satisfied by the opening. Therefore, only the amusement shop side can surely set the special effect mode only when the store is opened. In addition, since the first symbol combination game is started from the time when the power is turned on, for example, in order to set the special effect mode even when the power is simultaneously turned on for a large number of pachinko machines 10 Enough time can be secured.

  (3) The selectable condition for setting the special performance mode is that the front frame 14 is opened and closed a plurality of times. For this reason, it is possible to set the special effect mode at the same time as adjusting the nail arranged on the game board 13 when the game store is opened. Therefore, it is possible to save time and labor on the game store side. While the pachinko machine 10 may be turned on during business, the front frame 14 is usually closed to prevent the player from touching the nails placed on the game board 13. Turn on the power. For this reason, only the amusement shop side can surely set the special effect mode.

  (4) The open sensor 29 is a position on the front surface side of the middle frame 12 and is disposed at a position covered by the front frame 14 when the front frame 14 is closed (see FIG. 2). Since the opening sensor 29 is disposed at such a position, it is possible to prevent a person other than the game store from operating the opening sensor 29 illegally. Further, since the opening sensor 29 is configured by a mechanical type (push button type), the game store side opens the opening sensor 29 with the front frame 14 opened without opening and closing the front frame 14 a predetermined number of times. It is also possible to set the special production mode by operating directly.

The middle frame collar piece 124 is formed from one side surface of the middle frame locking collar 121 so as to protrude toward the back side (outer frame 111 side) of the pachinko machine 110 when attached to the middle frame 112. The middle frame collar 124 is bent so that the tip is directed upward when attached to the middle frame 112. Each middle frame collar 124 is formed so as to be engageable with an engagement piece 118 (see FIG. 11) disposed on the right frame portion 111 a of the outer frame 111. When the middle frame collar 124 is engaged with the engagement piece 118, the middle frame 112 cannot be opened with respect to the outer frame 111. The engaging piece 118 is a flat plate member fixed to the right frame portion 111 a of the outer frame 111.

  Further, as shown in FIG. 10, the front frame locking rod 122 is provided with front frame collar pieces 125 each having a hook-shaped tip projecting at three positions in the vertical direction. The front frame collar piece 125 is formed from one side surface of the front frame locking collar 122 so as to protrude toward the machine surface side (front frame 113 side) of the pachinko machine 110 when attached to the middle frame 112. Further, the front frame flange 125 is bent so that the tip is directed downward when attached to the middle frame 112. And the front frame collar 125 is formed so that engagement with the engagement hole 119 (refer FIG. 8) arrange | positioned at the open | release side edge part of the front frame 113 is possible. When the front frame flange 125 is engaged with the engagement holes 119, the front frame 113 cannot be opened with respect to the middle frame 112.

  The middle frame locking rod 121 and the front frame locking rod 122 are provided with through holes 121a to 121c and 122a to 122c at three locations, respectively. The middle frame locking rod 121 is fixed to the right frame portion 112a of the middle frame 112 through the through holes 121a to 121c by three caulking pins 126a to 126c. The front frame locking rod 122 is fixed to the right frame portion 112a of the middle frame 112 through the through holes 122a to 122c by the three caulking pins 126a to 126c in a state where the front frame locking rod 122 is arranged outside the middle frame locking rod 121. Is done. The caulking pin 126a is connected to the middle frame locking rod 121 and the front frame locking rod 122 through a through hole 121a formed in the upper portion of the middle frame locking rod 121 and a through hole 121a formed in the upper portion of the front frame locking rod 122. Is fixed. The caulking pin 126c fixes the middle frame locking rod 121 and the front frame locking rod 122 through a through hole 121c formed in the lower portion of the middle frame locking rod 121 and a through hole 121c formed in the lower portion of the front frame locking rod 122. is doing. The caulking pin 126b includes a through-hole 121b formed between the through-hole 121a and the through-hole 121c, and a through-hole 122b formed between the through-hole 122a and the through-hole 122c. Locking rod 122 is fixed. The through holes 121a to 121c and 122a to 122c are formed in a vertically long shape along the vertical direction (longitudinal direction of the middle frame locking rod 121 or the front frame locking rod 122), and the middle frame locking rod 121 and the front frame locking The flange 122 is slidable in the vertical direction along the through holes 121a to 121c and 122a to 122c.

  The locking mechanism actuating member 123 includes a mounting portion 127, a cylinder lock 128, and a cam 129 in which two protrusions 129a and 129b are formed. The outer cylinder 128b of the cylinder lock 128 is fixed to the mounting portion 127 along the front-rear direction of the pachinko machine 110 so that the key hole of the cylinder lock 128 faces the machine surface side. The attachment portion 127 is formed by an inner side surface of the right frame portion 112a of the middle frame 112 (on the side surface opposite to the side on which the middle frame locking rod 121 is attached) by caulking pins 126b and 126c to which the middle frame locking rod 121 and the front frame locking rod 122 are fixed. ). A cam 129 is fixed to a cylinder (inner cylinder) 128a of the cylinder lock 128, and the cam 129 is fixed to the outer cylinder 128b together with the cylinder 128a. The cam 129 is fixed to the side of the cylinder 128a where the keyhole is not formed.

  The protrusions 129a and 129b included in the cam 129 are formed so as to protrude in the direction perpendicular to the rotation direction (that is, from the center toward the outer periphery). Further, the protrusion 129a is formed with the other protrusion 129b with an interval of approximately 90 degrees. When the cam 129 is fixed to the cylinder 128a, the protrusion 129a disposed at the upper part is bent and formed in a substantially Z shape, and when the cylinder 128a is rotated, a locus drawn by the tip of the protrusion 129a, The locus drawn by the tip of the projection 129b is shifted in the front-rear direction of the pachinko machine 110.

  When the cam 129 is fixed to the cylinder 128a, the projection 129b disposed below the projection 129a is formed in the slit 112f formed in the middle frame 112 along the vertical direction and the middle frame locking rod 121. The engagement hole 131 formed in the front frame locking rod 122 can be engaged through the engagement hole 131. Therefore, when the cylinder 128a of the cylinder lock 128 is rotated counterclockwise (X direction shown in FIG. 10), the protrusion 129b engages with the engagement hole 130 of the front frame locking rod 122. When a force is further applied to rotate the cylinder 128a counterclockwise, the front frame locking rod 122 is slidable in the vertical direction, so that it is pushed upward by the protrusion 129b. As a result, the engagement between the front frame collar 125 and the engagement hole 119 of the front frame 113 is released, and the front frame 113 can be released from the middle frame 112.

  Further, when the cam 129 is fixed to the cylinder 128a, the protrusion 129a disposed above the protrusion 129b causes the cylinder 128a to rotate in the clockwise direction (the direction opposite to the X direction shown in FIG. 10). It can be engaged with an engagement hole 131 formed in the middle frame locking rod 121 through a slit 112 f formed in the frame 112. For this reason, when the cylinder 128 a of the cylinder lock 128 is rotated clockwise, the protrusion 129 a is engaged with the engagement hole 131 of the middle frame locking rod 121. When a force is further applied to rotate the cylinder 128a clockwise, the cylinder 128a is pushed by the protrusion 129a and moves downward. As a result, the engagement between the middle frame collar 124 and the engagement piece 118 of the outer frame 111 is released, and the middle frame 112 can be released from the outer frame 111. Therefore, in this embodiment, when the protrusion 129b rotates the cam 129 in the X direction, the driving force from the cam 129 is applied to the front frame locking rod 122 via the slit (through hole) 112f of the right frame 112a. It becomes the first protrusion that transmits and releases the engagement with the front frame 113. Further, when the protrusion 129a rotates the cam 129 in the direction opposite to the X direction, the driving force from the cam 129 is transmitted to the middle frame locking rod 121 through the slit (through hole) 112f of the right frame 112a. Thus, the second protrusion is released from the engagement with the middle frame 112.

  And the locking mechanism action | operation member 123 of the locking device 120 is accommodated in the accommodation recessed part 112e formed in the lower frame part 112d of the middle frame 112, as shown in FIG. The housing recess 112e is provided at the right end of the lower frame portion 112d, and is open on the front side and the right side (right frame portion 112a side) of the pachinko machine. Specifically, the accommodation recess 112e is formed in an L-shaped horizontal section. That is, the housing recess 112e is formed with a machine front side opening that opens to the machine front side and a side opening that opens to the right frame 112a side. The machine front side opening is formed so that the keyhole of the cylinder lock 128 accommodated in the accommodation recess 112e is exposed to the machine front side. The side opening has a size that allows the locking mechanism actuating member 123 installed in the right frame 112a to pass therethrough.

  The right opening (side opening) is closed by the right frame 112 a of the middle frame 112. Further, the opening on the front side (machine surface side opening) is closed by a cover member 132 that constitutes the lower frame portion 112d. The cover member 132 is formed with a through-hole 132a for exposing the front side portion of the cylinder lock 128 (that is, only the key hole). In other words, the cover member 132 is formed so as to expose the machine front side portion of the cylinder lock 128 (that is, only the keyhole) and completely close the machine front side opening of the other housing recess 112e. In the present embodiment, the cover member 132 and the right frame portion 112a constitute a closing member. The opening on the machine front side has a size that allows the cylinder lock 128 accommodated in the accommodation recess 112e to pass through, and the side opening is closed by the right frame 112a. The lock 128 can be exchanged.

  Further, the locking mechanism operating member 123 is provided with an unlocking detection sensor 140 for detecting that the cylinder lock 128 is unlocked. As shown in FIG. 12A, when the protrusion 129b of the cam 129 moves onto the unlock detection sensor 140 and the light emitted from the unlock detection sensor 140 is blocked, the unlock detection sensor 140 , Detecting that the cylinder lock 128 is not unlocked. On the other hand, as shown in FIG. 12B, when the protrusion 129b of the cam 129 rotates in the X direction and moves from above the unlock detection sensor 140, the light emitted from the unlock detection sensor 140 is blocked. Disappear. At this time, the unlock detection sensor 140 detects that the cylinder lock 128 is unlocked. The same applies when the protrusion 129b rotates in the direction opposite to the X direction. In this embodiment, the protrusion 129b moves and the front frame 113 or the middle frame 112 is released regardless of whether the cam 129 is rotated in the X direction or in the direction opposite to the X direction. The Rukoto. Therefore, either the front frame 113 or the middle frame 112 is opened by providing only one unlock detection sensor 140 for detecting the movement of the protrusion 129b without providing a sensor for detecting the movement of the protrusion 129a. Can be detected. Moreover, in this embodiment, the unlock detection sensor 140 comprises an unlock detection means.

  Further, the middle frame 112 is provided with a door opening detection switch 141 for detecting that the front frame 113 is opened or that the middle frame 112 is opened. As shown in FIG. 13, the door opening detection switch 141 is housed in a housing hole 142 provided on the upper right side of the middle frame 112. The accommodation hole 142 penetrates in the front-rear direction, and the door opening detection switch 141 accommodated in the accommodation hole 142 can contact the front frame 113 and the outer frame 111 when closed as shown in FIG. It has become. The door open detection switch 141 is fixed to the switch holder 143 and is fixed to the middle frame 112 via the switch holder 143. One end (left end portion) of the switch holder 143 in the longitudinal direction is fixed to the middle frame 112 so as to be rotatable about a fixed shaft. Further, the switch holder 143 is applied with an elastic force so as to rotate to the rear side (the outer frame 111 side) of the pachinko machine 110 by a spring 144 attached to a fixed shaft.

  In addition, a lever 145 that is rotatably fixed is provided on an end of the door opening detection switch 141 opposite to the fixed shaft and on the side surface of the front frame 113. Further, the door opening detection switch 141 is provided with a push button 146 on the side surface on the front frame 113 side. The push button 146 is disposed in the vicinity of the fixed shaft of the lever 145, and the lever 145 is pressed against the front frame 113 by the push button 146 of the door opening detection switch 141. For this reason, when the front frame 113 is opened, the lever 145 is not subjected to the pressing force from the front frame 113 as shown in FIG. 13, and the lever 145 is pushed by the push button 146 to rotate and push. The button 146 does not receive a pressing force from the lever 145. Thereby, since the push button 146 is restored, the door opening detection switch 141 detects that the front frame 113 or the middle frame 112 is opened.

  When the middle frame 112 is opened, the switch holder 143 rotates to the outer frame 111 side by the elastic force of the spring 144 as shown in FIG. Then, a gap is formed between the front frame 113 and the door opening detection switch 141, and the lever 145 does not receive the pressing force from the front frame 113. Thereby, since the push button 146 is restored, the door opening detection switch 141 detects that the front frame 113 or the middle frame 112 is opened. In the present embodiment, the door opening detection switch 141 constitutes a front frame detection unit. Further, the door opening detection switch 141 constitutes a middle frame detection means.

The pachinko machine 110 is provided with various effect devices for performing game effects.
For example, as shown in FIG. 6, on the front side of the front frame 113, there is provided a frame lamp 16a that is turned on (flashes) or turned off to perform a light emission effect based on the light emission decoration. In the game area of the game board 114, a game board lamp 16b that is turned on (flashes) or turned off to perform a light emission effect based on the light emission decoration is provided. In addition, speakers 17 that output various sounds (sound effects) and perform sound effects based on the sound output are provided on both the left and right sides of the upper portion of the front frame 113 (shown by broken lines). A speaker 17 that outputs various sounds (sound effects) and performs sound effects based on the sound output is also provided on the left side of the lower part of the outer frame 111. In addition, a display device 21 having a variable display H on which a symbol combination game is played is disposed in the approximate center of the game area of the game board 114. The pachinko machine 110 is provided with a main control board 30, an overall control board 31, a display control board 32, a lamp control board 33, and an audio control board 34 on the back side of the machine. The main control board 30 is configured to be able to input an opening signal indicating opening of the machine frame (the front frame 113 and the middle frame 112) from the door opening detection switch 141. The main control board 30 is configured to be able to input an unlocking signal indicating that the locking device 120 is unlocked from the unlocking detection sensor 140.

  In the second embodiment, the production mode can be selected from the output order and the output count of the opening signal from the door opening detection switch 141 and the unlocking signal from the unlocking detection sensor 140. Hereinafter, in the second embodiment, various processes executed when the main CPU 30a and the overall CPU 31a select the effect mode will be described.

  When the unlock signal is input from the unlock detection sensor 140, the main CPU 30a determines whether 0 is set in the setting period flag. When the determination result is affirmative (when the setting period flag is set to 0), the main CPU 30a rewrites the unlocking count value by adding 1 to the unlocking count value indicating the unlocking count of the locking device 120. Note that the unlock count value is stored in the RAM 30c, and is set to 0 (initial value) when the power is turned on.

  Then, the main CPU 30a determines whether or not the unlock count value has reached a predetermined value (5 times in the present embodiment). When the determination result is affirmative (when the unlocking count value reaches 5), the main CPU 30a sets 1 to the unlocking flag indicating that the unlocking count value has reached a predetermined value.

  When an opening signal is input from the door opening detection switch 141, the main CPU 30a determines whether 1 is set in the unlocking flag. When the determination result is affirmative (when the unlock flag is set to 1), the main CPU 30a adds 1 to the open / close count value indicating the open / close count value of the front frame 113 or the middle frame 112, and sets the open / close count value. rewrite.

  Then, the main CPU 30a determines whether or not the opening / closing frequency value has reached a predetermined value (5 times in the present embodiment). When the determination result is affirmative (when the number of opening / closing times reaches 5), the main CPU 30a outputs a mode change signal that instructs the overall control board 31 (overall CPU 31a) to change the effect mode.

  And general CPU31a will set special production mode as production mode, if a mode change signal is inputted from main CPU30a. That is, the overall CPU 31a sets the production mode 2 or the production mode 3. Specifically, the overall CPU 31a determines one effect mode from the special effect modes by random number lottery. Then, the overall CPU 31a sets 1 or 2 to the mode flag indicating the rendering mode based on the random number lottery result, and stores it in the RAM 31c. Accordingly, in the present embodiment, the overall CPU 31a serves as a selection unit that selects the special effect mode. Further, in the present embodiment, the main CPU 30a serves as a measurement unit that measures the number of outputs of the release signal (detection signal) and the unlock signal separately. Further, the main CPU 30a determines whether the unlock signal (detection signal) has been output a predetermined number of times and whether the release signal (detection signal) has been output a predetermined number of times. It becomes a judgment means.

  As described above, if the selectable condition that the front frame 113 or the middle frame 112 is opened and closed a predetermined number of times after the locking device 120 is unlocked a predetermined number of times is not selected, the special effect mode is not selected. For this reason, those who can satisfy the selection condition are those at the game store side, and only the game store side can set the special effect mode. Further, the game store normally does not open and close the front frame 113 or the middle frame 112 a plurality of times after unlocking the locking device 120 a plurality of times in order to adjust the pachinko machine 110. For this reason, the amusement store performs an unlocking operation and an opening / closing operation with the intention of changing the production mode, and even if the front frame 113 or the middle frame 112 is opened / closed for adjustment of the pachinko machine 110, the production mode Can be prevented from changing.

  Next, the timing at which the effect mode is switched in the second embodiment will be described with reference to FIG. FIG. 16A shows a case where the locking device 120 is not unlocked a predetermined number of times (five times) from when the power is turned on until the first symbol combination game is started. In FIG. 16B, the locking device 120 is unlocked a predetermined number of times (five times) from when the power is turned on until the first symbol combination game is started. Is shown when it is not opened a predetermined number of times (five times). In FIG. 16C, the front frame 113 is unlocked a predetermined number of times (5 times) after the locking device 120 is unlocked a predetermined number of times (5 times) from when the power is turned on until the first symbol combination game is started. ) Shown when opened and closed.

  As shown in FIG. 16A, when the power is turned on (time point A11), 0 is set in the mode flag, and the normal effect mode (effect mode 1) is set as the effect mode. At this time, 0 is set in the setting period flag. Here, even after the locking device 120 is unlocked once (time point A12) from when the power is turned on until the first symbol combination game is started (time A12), the front frame 113 or the middle frame 112 may be released multiple times ( At time points A13 to A15), the main CPU 30a does not output a mode change signal. When the first symbol combination game is started (time point A16), the main CPU 30a sets 1 to the setting period flag. Thereafter, the production mode cannot be set.

  As described above, from the time the power is turned on until the first symbol combination game is started, the locking device 120 is unlocked, the front frame 113 or the middle frame 112 is opened, and then the gaming machine is adjusted (for example, Even if the setting of the nail is performed, if the number of times of unlocking of the locking device 120 is less than 5, the special effect mode is not set.

  As shown in FIG. 16B, when the power is turned on (time point B11), the mode flag is set to 0, and the normal effect mode (effect mode 1) is set as the effect mode. At this time, 0 is set in the setting period flag. Here, if the locking device 120 is unlocked a plurality of times during the period from when the power is turned on until the first symbol combination game is started (time points B12 to B16), the main CPU 30a unlocks the signal every time it is unlocked. And 1 is added to the unlock count value. When the unlock count value reaches a predetermined value (five times), the main CPU 30a sets the unlock flag to 1 (time point B16). Thereafter, even if the front frame 113 or the middle frame 112 is opened only once (time point B17), the main CPU 30a does not output a mode change signal. When the first symbol combination game is started (time point B18), the main CPU 30a sets 1 to the setting period flag. Thereafter, the production mode cannot be set. As described above, the unlocking operation of the locking device 120 is performed five times or more from when the power is turned on until the first symbol combination game is started, and then the front frame 113 or the middle frame 112 is released, and then the game Even if the machine is adjusted (for example, setting of a nail), if the number of times of opening / closing the front frame 113 or the middle frame 112 is less than 5, the special effect mode is not set.

  Then, as shown in FIG. 16C, when the power is turned on (time C11), 0 is set in the mode flag, and the normal effect mode (effect mode 1) is set as the effect mode. At this time, 0 is set in the setting period flag. Here, when the locking device 120 is unlocked between the time when the power is turned on and the time when the first symbol combination game is started (time points C12 to C16), the main CPU 30a inputs an unlocking signal every time it is unlocked. Then add 1 to the unlock count value. When the unlock count value reaches a predetermined value (five times), the main CPU 30a sets 1 to the unlock flag (time C16). If the front frame 113 or the middle frame 112 is released a plurality of times from the time when the unlock flag is set to 1 until the first symbol combination game is started (time C17 to C21), the main CPU 30a is released. Each time a release signal is input, 1 is added to the release count value. Then, when the number of times of opening reaches a predetermined value (5 times) (time C21), the main CPU 30a outputs a mode change signal to the overall control board 31 (overall CPU 31a).

  The general CPU 31a inputs the mode change signal to set the special effect mode (effect mode 2 or effect mode 3) as the effect mode. Here, description will be made assuming that the rendering mode 2 is set as the special rendering mode as a result of the random lottery. Therefore, the overall CPU 31a sets 1 to the mode flag. Thereafter, when the first symbol combination game is started (time C22), the overall CPU 31a sets 1 to the setting period flag. For this reason, after this, even if the front frame 113 or the middle frame 112 is opened, the effect mode cannot be set.

As described above in detail, this embodiment has the following effects in addition to the effects (1) to (3) of the first embodiment.
(5) The opening order of the machine frame (front frame 113 or middle frame 112) and the locking device 120 is predetermined. That is, the machine frame cannot be opened until the locking device 120 is unlocked. For this reason, the detection signal from the door open detection switch 141 cannot be input unless the detection signal from the unlock detection sensor 140 is input. Therefore, in this embodiment, the general CPU 31a inputs the detection signal from the unlock detection sensor 140 a predetermined number of times in accordance with the output order of the detection signal, and then inputs the detection signal from the door opening detection switch 141 a predetermined number of times. The production mode is set. Thereby, the production mode can be set according to the adjustment of the pachinko machine 10, and the effort for setting the production mode can be reduced.

  (6) A plurality of detection means such as the unlock detection sensor 140 and the door opening detection switch 141 are provided, and the number of times of detection signal output is measured separately, and when each inputs a predetermined number of times, the overall CPU 31a performs the special effect mode. I set it. For this reason, it is possible to reduce the possibility that the special performance mode is erroneously set as compared with the case where there is one detection means.

In addition, the said embodiment can be embodied in another embodiment (another example) as follows.
In the first embodiment, the selectable condition for selecting the special performance mode is that the front frame 14 is open. However, if the condition is that only the amusement shop can do it, it may be changed. good. For example, the selectable condition may be that at least one of the front frame 14, the middle frame 12, and the upper ball tray 15 that can be opened only at the amusement store side is repeatedly opened and closed a predetermined number of times. Alternatively, it may be set as a selectable condition that the lock 28 has been unlocked a predetermined number of times or more (turned the key a plurality of times).

In the first embodiment, the upper ball tray 15 and the lower ball tray 18 are separate members, but may be integrally formed.
In the above embodiment, the selection period is from when the power is turned on until the first symbol combination game is started (the first effect pattern designation command is output), but the game store prepares for the opening of the pachinko machine 10 As long as it is a period during which adjustment is performed, it may be arbitrarily changed. For example, the selection period may be a period from when the power is turned on until a predetermined period (for example, 10 minutes) elapses. In such a case, the special effect mode can be set even after the symbol combination game is performed to check the operation of the variable display H. Further, the selection period may be from when the power is turned on until a plurality of game control signals related to a predetermined symbol variation game (for example, an effect pattern designation command, an all symbols stop command, a symbol designation command, etc.) are input.

  The overall CPU 31a of the above embodiment has set one effect mode from the special effect modes by random lottery, but can specify any effect mode from the effect modes included in the special effect mode. May be. For example, the production mode may be designated in accordance with the number of times of opening signal output (number of times the front frame 14 is opened and closed). That is, when the number of outputs of the release signal is 5, the mode may be changed to the production mode 2, and when the number of output is 10, the mode may be changed to the production mode 3. Thereby, the amusement store can set an arbitrary production mode from a plurality of special production modes.

  In the above embodiment, the type of effect mode may be arbitrarily selected. For example, the production mode may be changed every time the number of times of opening signal output increases by three. That is, when the number of output of the release signal is 3, the mode is changed to the production mode 2, when the output number is 6, the mode is changed to the production mode 3, when the number of output is 9, the mode is changed to the production mode 1. The production mode may be changed. Also, for example, in the second embodiment, when the number of times the release signal is output is 3 to 5 and the number of times the unlock signal is output is 3 to 5, the rendering mode 2 is set and the release signal is opened. When the signal output count is 6 times or more and the unlock signal output count is 6 times or more, the effect mode 3 may be set.

In the above embodiment, the open sensor 29 is a push button type, but may be arbitrarily changed. For example, a touch sensor type (contact type) may be used.
In the above embodiment, the normal production mode may be set until a predetermined selection period elapses after the power to the pachinko machine 10 is turned on. In this case, for example, a switch that can set the normal effect mode may be provided, or the normal effect mode may be set by turning the operation handle of the launching device 19 when the front frame 14 is opened. In this way, when the special effect mode is set by mistake, it is not necessary to turn off the power to the pachinko machine 10 and start again.

  In the above embodiment, the appearance rate of the jackpot notice is changed by changing the special effect mode, but the appearance rate of the reach effect may be changed. The reach effect refers to an effect that is performed during the period from when a reach is formed (reach combinations are displayed) to when a jackpot combination or a combination of outliers is displayed or once displayed. Moreover, you may change the display content of a symbol by changing special production modes. Moreover, you may change a number symbol to a character symbol by changing to special production mode. Moreover, you may increase / decrease the number of effective lines in which the displayed symbol combination becomes effective by changing to special effect mode. Further, by changing to the special effect mode, the background displayed on the variable display H may be changed, or the music to be output and the light emission pattern of the lamp may be changed.

○ Although the special effect mode of the above embodiment is two, it may be changed to an arbitrary number. One may be sufficient and three or more may be sufficient.
In the above embodiment, the notification mode may be notified by the notification means. For example, the general CPU 31a may output a command indicating the type of effect mode to the display control board 32 based on the mode flag, and the sub CPU 32a may display the type of effect mode on the variable display H based on the command. good.

  In the above embodiment, the main control board 30 (main CPU 30a) measures the number of outputs of the open signal and determines whether the number of outputs has reached a predetermined number of times. You can go. For example, the overall control board 31 (overall CPU 31a) may perform this.

  In the first embodiment, the opening mode 29 for detecting the opening of the front frame 14 is provided, and it is determined whether or not the number of outputs of the detection signal from the opening sensor 29 has reached a predetermined value. Had changed. As another example, in addition to the opening sensor 29, an unlock detection sensor as an unlock detection means for detecting that the lock 28 has been unlocked is provided, and the number of outputs of detection signals output from these sensors is set for each. The effect mode may be changed by separately measuring and determining whether or not the number of times of output has reached a predetermined value. In addition, as an effect mode change condition, an output order of detection signals output from each of the plurality of sensors may be set in advance, and whether to execute the change may be determined depending on whether the output order matches the output order.

  Specifically, the overall CPU 31a sets the number of times the unlock detection signal is output each time an unlock detection signal for detecting that the lock 28 is unlocked is input from the unlock detection sensor until the selection period elapses. measure. Then, each time the unlocking detection signal is input, the overall CPU 31a determines whether or not the number of times of output of the unlocking detection signal has reached a predetermined number of times of 2 or more (for example, 3 times). When this determination result is affirmative, the overall CPU 31a measures the number of times the detection signal is output each time a detection signal for detecting that the front frame 14 is opened is input from the opening sensor 29 until the selection period elapses. . Then, every time the detection signal is input, the overall CPU 31a determines whether or not the number of output of the detection signal has reached a predetermined number of times of 2 or more (for example, 5 times). If the determination result is affirmative, the overall CPU 31a may set a special effect mode.

  In addition, instead of the opening sensor 29 and the unlocking detection sensor, a middle frame detection sensor as a middle frame detection means for detecting that the middle frame 12 has been opened, and a dish member for detecting that the upper ball tray 15 has been opened. You may use the plate member detection sensor as a detection means. Moreover, in the said another example, although two sensors were used, you may use combining 3 or more. In the above example, the number of output of the detection signal from the opening sensor 29 is measured after the number of times of output of the unlock detection signal reaches the predetermined number. However, the number of times of output for each sensor (for each signal) during the selection period. When each reaches a predetermined number of times set in advance, the effect mode may be changed. Moreover, in the said another example, after determining the output frequency | count of an unlocking detection signal, the output frequency | count of the detection signal was determined, However, You may change the determination order arbitrarily.

  The opening order of the front frame 14, the middle frame 12, the upper ball tray 15, and the lock 28 is determined in advance by its structure. For example, unless the lock 28 is unlocked, the front frame 14 and the middle frame 12 cannot be opened. For this reason, the output order of the output signals output from the opening sensor 29, the unlock detection sensor, the middle frame detection sensor, and the dish member detection sensor is predetermined. That is, the output order of the detection signals is determined according to the opening order of the front frame 14, the middle frame 12, the upper ball tray 15, and the lock 28, such as the detection signal is output from the release sensor 29 after the unlock detection signal is output. It has been. For this reason, in the another example, the overall CPU 31a may determine the number of times each detection signal is output in the order of output. In this way, the effect mode can be set according to the adjustment of the pachinko machine 10, and the effort for setting the effect mode can be reduced.

  In the second embodiment, a lower ball tray open detection sensor that detects the opening of the lower ball tray 117 may be provided. The general CPU 31a measures the number of outputs of the detection signal from the lower ball tray opening detection sensor after the unlock flag is set to 1, and the special effect is obtained when the number of times of output reaches the predetermined number. A mode may be set.

  In the second embodiment described above, the output order of the opening signal from the door opening detection switch 141 and the unlocking signal from the unlocking detection sensor 140 is considered, but it may not be considered. That is, the number of outputs of the opening signal from the door opening detection switch 141 and the number of times of outputting the unlocking signal from the unlocking detection sensor 140 are measured separately, and the special effect mode is set when the number of outputs reaches a predetermined number. You may make it set.

  In the second embodiment, the output order of the opening signal from the door opening detection switch 141 and the unlocking signal from the unlock detection sensor 140 may be changed. For example, after the opening signal is input a predetermined number of times, the number of times the unlocking signal is output may be measured, and the special effect mode may be set when the output number reaches the predetermined number.

In the second embodiment, instead of the door opening detection switch 141, a lower ball tray opening detection sensor for detecting the opening of the lower ball tray 117 may be provided.
