Description

  The present invention relates to a gaming machine in which a display screen for displaying various images can be concealed by a mechanically concealing means.

  For example, in a pachinko machine, there is a liquid crystal display or other display means in the game area, and the display means variably displays symbols for lottery drawing or displays various effect images, notification images, etc. according to the game state. It is common.

Furthermore, in order to make the effect by the image display on the display means more effective, the concealment means that can be changed between a closed state that conceals at least a part of the display screen and an open state that is open (for example, it can be opened and closed in the vertical direction). There is already known a pachinko machine provided with a curtain or the like and performing an effect in which the opening / closing operation of the concealing means is combined with the image display on the display means (for example, Patent Document 1).
JP 2002-253799 A

  In a conventional pachinko machine equipped with a concealing means as described above, if an operation abnormality occurs such as the concealing means being unable to open or close, it becomes impossible or difficult to continue the game regardless of the state of the abnormality. It was necessary to take measures such as forcibly stopping the game by giving an error notification.

  That is, for example, when the concealment means hides the display screen and the operation in the opening direction becomes impossible, the player cannot continue viewing the game normally because the player cannot visually recognize the image displayed on the display screen. Even if the concealing means cannot operate in the closing direction with the display screen open, the game proceeds on the assumption that the concealing means hides at least a part of the display screen. This is because the game cannot be continued normally.

  As described above, in the conventional pachinko machine equipped with the concealing means, the game is interrupted every time the concealing means operates abnormally even though the concealing means is merely a production means, and the game progresses smoothly. There were not a few problems in this regard.

  In view of such a conventional problem, an object of the present invention is to provide a gaming machine that does not hinder the progress of a game as much as possible even if an operation abnormality occurs in the concealing means.

The present invention includes a display means 31 capable of variably displaying game information on the display screen 32a, a display control means 115 for controlling the display of the display means 31, and a closed state and an open state for hiding at least a part of the display screen 32a. In a gaming machine comprising a concealing means 34 that can be changed to an open state and an opening / closing control means 105 that performs opening / closing control of the concealing means 34 based on a predetermined opening / closing command, the concealing means 34 is in the closed state. A closing state detecting means 42 for detecting this, and an error determining means 106 for determining an abnormal operation of the concealing means 34. The display control means 115 controls the opening / closing control means 105 based on the opening / closing command. wherein in synchronization with the opening and closing operation of the concealed device 34 is configured to display a moving image of the opening and closing operation by the concealing means 34 on the display unit 31 by the switching control hand 105, the operation of the concealing means 34 by the error judging means 106 on the condition that the closed state is not detected by the closed state detecting means 42 in spite of reaching the maximum operation amount in the closing operation of the concealing means 34. When an abnormality is determined, the concealing means 34 is operated in the opening direction, and thereafter the concealing means 34 is not opened / closed even when the opening / closing command is issued .

  According to the present invention, even when the concealing unit 34 is abnormal and becomes inoperable, at least when the concealing unit 34 is stopped with the display screen 32a opened, it is displayed on the display screen 32a. Information that can be recognized by the player regarding the game information is substantially the same as when the concealing means 34 is operating normally, and the game can be continued without any sense of incongruity until the abnormality is canceled. That is, even if an operation abnormality occurs in the concealing means 34, the progress of the game is not hindered as much as possible.

A function for transmitting a variation control command of a normal symbol such as is provided.

  The normal profit state generating means 85 is a special symbol starting means based on the fact that the determination result by the hit determination function of the normal symbol processing means 84 is a hit determination, and the normal symbol after the fluctuation of the normal symbol display means 61 becomes a hit mode. A normal profit state in which the 26 open / close claws 26a are opened for a predetermined time is generated.

  The special random number creation processing means 86 is used for selection of a stop symbol when the special symbol after change becomes a big hit mode, in addition to the random number for jackpot determination used for determining whether or not the special symbol after change is set as the big hit mode. A special random number generating process for repeatedly generating a random number for a jackpot symbol, a random number for variation pattern selection used for selecting a variation pattern for a special symbol, and other predetermined random numbers is performed.

  By the special random number generation processing by the special random number generation processing means 86, for example, the big hit determination random number is repeatedly generated in the range of 294 from 0000H to 0125H, and the big hit symbol random number is generated in the range of 10 from 00H to 09H.

  The special start port check processing means 87 performs processing based on the detection of the game ball by the special symbol start means 26, and is generated by the special random number generation processing means 86 on condition that the special symbol start means 26 detects the game ball.

  The special symbol processing means 89 performs processing related to special symbols, and includes a jackpot determination processing means 94, a special stop symbol selection processing means 95, a variation pattern selection processing means 96, and the like.

  The jackpot determination processing means 94 performs a jackpot determination as to whether or not the changed special symbol is to be a jackpot mode by random number lottery. The special symbol display means 62 is in a state where it can be displayed in a variable manner and is stored in the special random number storage means 88. When one or more jackpot determination random number values are stored (when the number of special hold is one or more), the jackpot determination random number value stored first in the special random number storage means 88 is taken out and used for the jackpot determination The jackpot / miss determination is performed based on whether or not the random value matches a predetermined jackpot determination value.

  The special stop symbol selection processing means 95 selects the stop symbol after the fluctuation of the special symbol, and stores the big hit / loss determination result by the big hit determination processing means 94 and the special random number storage means 88 together with the random number for jackpot determination. The stop symbol after the change of the special symbol is selected on the basis of the jackpot symbol random value.

  For example, when the determination result by the jackpot determination processing means 94 is a jackpot determination, any one of “0” to “9” which is a jackpot pattern is selected based on the random number value for the jackpot symbol, and the jackpot determination When the determination result by the processing means 94 is a detachment determination, “-” which is a symbol of the detachment mode is selected. When the stop symbol of the special symbol is selected, for example, the special stop symbol number for setting the stop symbol of the special symbol is 00H to 09H corresponding to the symbols “0” to “9” of the big hit mode, Any of 0AH corresponding to “−” which is a symbol of the detachment mode is set.

  The variation pattern selection processing unit 96 selects a variation pattern of the production special symbol, and selects one of a plurality of types of special symbol variation patterns based on the determination result of the big hit / loss by the big hit determination processing unit 94. Is configured to do.

  In the present embodiment, it is roughly divided into a reach jackpot variation pattern A that stops in a jackpot manner via a reach state, a reach loss variation pattern B that stops in a breakout manner via a reach state, and a reach state. There are three types of special symbol variation patterns which are broadly classified as a non-reach variation variation pattern C that stops in a disengagement mode without any problem. Further, the reach jackpot variation pattern A and the reach loss variation pattern B include, for example, the operation of the display concealment effect means 33 during the display variation, that is, the reach jackpot opening / closing variation pattern A1 and the reach failure opening / closing variation pattern B1 accompanied by the opening / closing operation of the book 34. And a reach jackpot variation pattern A0 and a reach-out variation pattern B0 that are not accompanied by the opening / closing operation of the book 34. The five types of variation patterns A0, A1, B0, B1, and C can be provided with one or a plurality of variation patterns having different variation times and variation contents.

  When the special stop symbol selection processing by the special stop symbol selection processing means 95 and the special symbol variation pattern selection processing by the variation pattern selection processing means 96 are completed, the special symbol variation is sent to the effect control board 72 via the control command transmission means 91. The pattern designation command and the special stop symbol designation command are transmitted, and then the special symbol stop command is transmitted in accordance with the passage of the variation time corresponding to the variation pattern selected by the variation pattern selection processing means 96. Yes.

  The special profit state generation means 90 is advantageous to the player based on the fact that the determination result by the jackpot determination processing means 94 is a jackpot determination and the special symbol after the change of the special symbol display means 62 becomes a jackpot mode such as “7”. A special profit state is generated, and after the special symbol after the change of the special symbol display means 62 becomes a big hit mode, the opening operation state in which the big winning means 27 is in an open state is set a predetermined number of times with an interval time between them. It is repeatedly generated (for example, 15 times).

  The control command transmission means 91 is for transmitting a predetermined control command to the sub-control board side such as the effect control board 72 by one-way communication to give a control command, and that the gaming machine main body 1 is turned on. Based on the function of transmitting the power-on command to the effect control board 72 and the like, and based on the control of the normal symbol processing means 84, normal symbols such as a normal symbol variation pattern designation command, a normal stop symbol designation command, a normal variation stop designation command, etc. A function for transmitting a variation control command to the effect control board 72 side, a special symbol variation pattern designation command, a special stop symbol designation command, a special symbol stop command, and other special symbol variation control commands based on the control of the special symbol processing means 89 Is transmitted to the effect control board 72 side, and the voice and lamp control functions are sent to the effect control board 72 side according to various game states. And a function of transmitting the command.

  The effect control board 72 controls the display means such as the display concealment effect means 33, the sound output means 9, and the lamp 65. The control command transmission / reception means 101, the display concealment control means 102, the sound control means 103, the lamp control means. 104 etc. are provided.

  The control command transmission / reception means 101 transmits various commands related to symbol display control to the symbol control board 73 side out of the control commands received from the main control substrate 71 and the control command received from the main control substrate 71 side. And a function for transmitting an error display designation command relating to various errors to the symbol control board 73 side.

  The display concealment control unit 102 performs control related to the display concealment effect unit 33. The display concealment control unit 105 controls the opening / closing operation of the book 34 based on a predetermined opening / closing command, and the error determination unit determines an operation abnormality of the book 34. 106 or the like, and performs origin return processing, sensor state confirmation processing, normal opening / closing processing, etc. of the display hiding effect means 33 at a predetermined timing.

  The origin return process is a process for returning the book 34 to a predetermined origin position, for example, a fully open position. For example, when the gaming machine main body 1 is turned on and the presentation control board 72 is supplied with power. Although it is performed, in the present embodiment, it is also performed at the start of each variation of the special symbol.

  The origin return process is performed, for example, according to the procedure shown in FIG. First, under the control of the opening / closing control means 105, the driving operation of the driving means 35 is started in the direction in which the notebook 34 is moved in the opening direction (S1). As a result, the driving means 35 is driven in the forward direction, whereby the winding shaft 36 rotates in the forward direction, and the pad 34 is sequentially wound around the winding shaft 36 from the upper end side.

  If the open state detection means 41 is turned on until the operation amount after the start of the drive operation reaches the maximum operation amount (S2: Yes), the drive operation of the drive means 35 is stopped at that time ( S4), the origin return process ends. Thereby, the book 34 stops in an open state (origin position). Of course, when the notebook 34 is at the origin position when the power is turned on, the open state detecting means 41 has already been turned on, so that the origin return process ends with the notebook 34 still stopped.

  Here, the maximum operation amount is equal to or equal to the operation amount required for movement between the closed state in which the closed state detection unit 42 is ON (detection state) and the open state in which the open state detection unit 41 is ON. Is set to a larger value. The maximum operation amount is set by, for example, the time required for movement between the closed state in which the closed state detecting unit 42 is ON (detected state) and the open state in which the open state detecting unit 41 is ON, and the driving unit. It may be determined whether or not the elapsed time since the start of driving 35 has reached the time set as the maximum operation amount.

  Alternatively, when a stepping motor is used as the driving means 35, the maximum operation amount is set according to the number of steps of the driving means 35 required for the notebook 34 to move between the closed state and the open state. It may be determined whether or not the number of steps from the start of driving reaches the number of steps set as the maximum operation amount.

  On the other hand, when the operation amount after the drive operation is started reaches the maximum operation amount without the open state detecting means 41 being turned on (S3: Yes), the open direction non-detection error processing (S5) is performed. After this is done, the origin return process ends.

  This open direction non-detection error process (S5) is performed in the procedure as shown in FIG. 8, for example. First, the open direction undetected error flag and the closed direction undetected error flag are checked (S11), and if any of them is already ON (S11: Yes), the subsequent processing is performed. In this case, the open direction non-detection error process ends.

  If neither the opening direction undetected error flag nor the closing direction undetected error flag is ON (S11: No), the driving operation of the driving means 35 is started at a low speed in the direction in which the book 34 is operated in the opening direction. (S12). As a result, the driving means 35 is driven in the forward direction at a low speed, whereby the winding shaft 36 rotates in the forward direction, and the pad 34 is sequentially wound around the winding shaft 36 from the upper side at a low speed.

  The reason why the winding operation of the book 34 is performed again at a low speed is because the torque of the driving means 35 is considered to be a cause of the failure of the first driving operation in the opening direction. If the cause is insufficient torque, the abnormality may be resolved by driving again at a low speed.

  If the open state detecting means 41 is turned on until the amount of operation after the drive operation at the low speed reaches the maximum amount of operation (S13: Yes), the drive operation of the drive unit 35 is performed at that time. The process is stopped (S15), and the open direction non-detection error process ends. Thereby, the book 34 stops in an open state (origin position).

  On the other hand, when the operation amount after the start of the low-speed driving operation reaches the maximum operation amount without the open state detection means 41 being turned on (S14: Yes), the error determination means 106 makes a check 34. The opening direction undetected error flag is set to ON (S16), and a padding operation error display designation command is transmitted to the symbol control board 73 side (S17), and the opening direction undetected error processing is completed. To do.

  The sensor state confirmation process is a process for confirming the state of the sensor of the display concealment effect means 33, that is, the open state detection means 41 and the closed state detection means 42. For example, the main control is performed when the gaming machine body 1 is turned on. This is performed based on the transmission of a power-on command from the board 71 to the effect control board 72 side.

  In the sensor state confirmation process, for example, as shown in FIG. 9, an opening operation confirmation process (S21), a closing operation confirmation process (S22), and an opening operation confirmation process (S23) are sequentially performed.

  Since the procedure of the opening operation confirmation process (S21, S23) is the same as the above-described origin return process (FIG. 7), the description thereof is omitted.

  The closing operation confirmation process (S22) is performed, for example, according to a procedure as shown in FIG. First, under the control of the opening / closing control means 105, the driving operation of the driving means 35 is started in the direction in which the notebook 34 is moved in the closing direction (S31). Thereby, the drive means 35 is driven in the reverse direction, whereby the take-up shaft 36 rotates in the reverse direction, and the padding 34 is sequentially fed out from the take-up shaft 36.

  If the closed state detection unit 42 is turned on until the operation amount after the drive operation starts reaches the maximum operation amount (S32: Yes), the drive operation of the drive unit 35 is stopped at that time ( S34), the closing operation confirmation process ends. Thereby, the book 34 stops in a closed state.

  On the other hand, when the operation amount after the start of the driving operation reaches the maximum operation amount without the closed state detecting means 42 being turned on (S33: Yes), the closing direction non-detection error processing (S35) is performed. After being performed, the closing operation confirmation process ends.

  This closing direction non-detection error process (S35) is performed, for example, according to the procedure shown in FIG. First, the open direction undetected error flag and the closed direction undetected error flag are checked (S41). If any of them is already ON (S41: Yes), the subsequent processing is performed. In this case, the closing direction non-detection error process ends.

  If neither the opening direction undetected error flag nor the closing direction undetected error flag is ON (S41: No), it is determined by the error determining means 106 that the book 34 is operating abnormally, and the closing direction undetected error flag is ON. (S42), a symbol operation error display designation command is transmitted to the symbol control board 73 side (S43).

  As described above, it is very unlikely that the error is determined without performing the driving in the closing direction again in the case of the abnormal driving operation in the closing direction due to insufficient torque of the driving means 35. This is because, if the drive in the closing direction is further performed when 34 is already in the closed state, the book 34 may be reversely wound around the take-up shaft 36 to cause a new abnormality.

  Thereafter, the drive operation of the drive means 35 is started at a low speed in the direction in which the notebook 34 is moved in the opening direction (S44). As a result, the driving means 35 is driven in the forward direction at a low speed, whereby the winding shaft 36 rotates in the forward direction, and the pad 34 is sequentially wound around the winding shaft 36 from the upper side at a low speed.

  If the open state detection means 41 is turned on until the amount of movement after the low-speed driving operation reaches the maximum amount of movement in the opening direction of the notebook 34 (S45: Yes), at that time. The driving operation of the driving means 35 is stopped (S47), and the closing direction non-detection error process is ended. In this case, since the drive in the opening direction has been normally performed, the book 34 stops in the open state (origin position) while the close direction non-detection error flag is ON.

  On the other hand, when the operation amount after the start of the low-speed driving operation reaches the maximum operation amount without the open state detecting means 41 being turned on (S46: Yes), the closing direction undetected error here. The process ends. In this case, not only the driving in the closing direction but also the driving in the opening direction cannot be performed normally. For example, when the drive means 35 is abnormal, the book 34 stops at a position between the open state and the closed state. For example, when the abnormality is caused by the detection means 41, 42, there is a possibility that the state is stopped due to an open state or the like.

  The normal opening / closing process is a process of opening / closing the book 34 in synchronization with the change of the special symbol and the effect special symbol, and the reach jackpot opening / closing variation pattern A1 or opening / closing variation with the opening / closing operation of the book 34 from the main control board 71 side. When a special symbol variation pattern designation command corresponding to the pattern B1 is received, the drive unit 35 is controlled by the control of the opening / closing control unit 105 to open / close the notebook 34 with a predetermined opening / closing pattern corresponding to the variation pattern. It is like that. Here, the special symbol variation pattern designating command corresponding to the reach jackpot opening / closing variation pattern A1 or the reach off / opening variation pattern B1 accompanying the opening / closing operation of the book 34 is an example of a predetermined opening / closing command.

  In the normal opening / closing process, a process similar to the closing operation confirmation process (FIG. 10) is performed when the notebook 34 is driven in the closing direction, and a process similar to the opening operation confirmation process (FIG. 7) is performed when the book 34 is driven in the opening direction. Each one is going to be done.

  Further, the opening / closing control means 105, when the error determination means 106 determines that the book 34 is operating abnormally, that is, when either the open direction undetected error flag or the close direction undetected error flag is ON. Is configured such that the opening / closing operation of the book 34 is not performed even when a special symbol variation pattern designation command corresponding to the reach jackpot opening / closing variation pattern A1 or the reach off / opening variation pattern B1 accompanying the opening / closing operation of the book 34 is received.

  The voice control means 103 performs voice output control of the voice output means 9 such as a speaker. The voice control means 103 performs a predetermined output from the voice output means 9 based on a voice control command from the main control board 71 side, a special symbol variation control command, or the like. Sound effects are output.

  The lamp control means 104 controls the display of the lamp 65 and the like, and causes the lamp 65 and the like to emit light in a predetermined pattern based on a lamp control command, a special symbol variation control command, etc. from the main control board 71 side. It has become.

  The symbol control board 73 performs display control of the normal symbol display means 61, the special symbol display means 62, the production special symbol display means 31, and the like. The control command receiving means 110, the normal symbol display control means 111, and the special symbol display control. Means 112, effect special symbol variation data storage means 113, effect stop symbol selection means 114, effect special symbol display control means (display control means) 115, error display control means 116, and the like.

  The control command receiving unit 110 receives a control command transmitted from the effect control board 72 and a control command transmitted from the main control board 71 via the effect control board 72.

  The normal symbol display control means 111 performs display control of the normal symbol display means 61 based on the normal symbol fluctuation control command from the main control board 71 side, and is designated when the normal symbol fluctuation pattern designation command is received. The normal symbol variation display is started on the normal symbol display means 61 in accordance with the normal symbol variation pattern, and when the normal variation stop designation command is received, the normal symbol is displayed in the stop symbol designated by the normal stop symbol designation command. It is configured to stop and fix the fluctuation.

  The special symbol display control means 112 performs display control of the special symbol display means 62 based on the special symbol variation control command from the main control board 71 side, and is designated when the special symbol variation pattern designation command is received. When the special symbol display means 62 starts the variation display of the special symbol according to the special symbol variation pattern and receives the special variation stop designation command, the stop symbol designated by the special stop symbol designation command, that is, the jackpot mode is set. It is configured to stop and confirm the variation of the special symbol at any one of “0” to “9” corresponding to “−” corresponding to the detachment mode.

  In the effect special symbol variation data storage means 113, the variation data of the effect special symbol by the effect special symbol display means 31 is stored in advance for each special symbol variation pattern. In the effect special symbol variation data corresponding to the reach jackpot opening / closing variation pattern A1 and the reach-uneven opening / closing variation pattern B1, the synchronism with the opening / closing pattern of the book 34 set corresponding to these variation patterns A1, B1 An open / close scene of a notebook is incorporated in the symbol variation image.

  The effect stop symbol selecting means 114 selects the stop symbol after the change of the effect special symbol, and is based on the special symbol change pattern specifying command and the special change stop specifying command received from the main control board 71 side. If the symbol variation pattern corresponds to the jackpot, the stop symbol corresponding to the jackpot mode such as “7, 7, 7”, “4, 4, 4” based on the stop symbol designated by the special variation stop designation command If the special symbol variation pattern is a reach deviating variation pattern, a random symbol lottery or the like will be used to select a stop symbol corresponding to a loss of reach such as “7, 5, 7”, or a special symbol variation pattern if the special symbol variation pattern is a non-reach variation pattern. A stop symbol corresponding to a non-reach outage such as “5, 6, 7” or the like is selected by lottery or the like.

  The effect special symbol display control means 115 performs display control of the effect special symbol display means 31 on the basis of the special symbol variation control command from the main control board 71 side, and when the special symbol variation pattern designation command is received. Then, the effect special symbol variation data storage means 113 reads the effect special symbol variation data corresponding to the special symbol variation pattern, starts the variation display based on the effect special symbol variation data on the effect special symbol display means 31, and the special variation When the stop designation command is received, the special symbol variation is stopped and confirmed by the stop symbol selected by the effect stop symbol selecting means 114.

  The error display control means 116 is for displaying an error on the effect special symbol display means 31 based on the error display designation command transmitted from the main control board 71, the effect control board 72, etc. The error display designation command Is configured to display an error at a predetermined timing.

  In this embodiment, when a screen operation error display designation command is received from the production control board 72 side, a screen operation error display is performed until a predetermined time (for example, 30 seconds) elapses after receiving the screen operation error display designation command. After receiving a padding operation error display designation command until a predetermined time (for example, 30 seconds) has elapsed after receiving a special symbol fluctuation pattern designation command corresponding to the reach jackpot opening / closing fluctuation pattern A1 or the reach off / opening fluctuation pattern B1 after receiving the designation command An error is displayed within each period of the demo.

  Next, the processing operation in the pachinko machine having the above-described configuration will be described more specifically with a focus on the processing operations related to the special symbol, the special effect design, and the display concealment production means 33.

  When power is turned on to the gaming machine main body 1 and power is supplied to the main control board 71, the effect control board 72, etc., the origin return process (FIG. 7) is performed under the control of the display concealment control means 102 of the effect control board 72. Is called.

  If there is no abnormality in the display concealment effect means 33 by this origin return processing, regardless of the stop position of the book 34 when the power is turned on, the book return 34 is opened (origin position) by the origin return processing, that is, detected. The unit 43 is wound up to a position detected by the open state detection means 41 and stops (S4) (see FIG. 12), but the drive means 35, the pad 34, the open state detection means 41, etc. are abnormal, and the drive means 35 If the open state detecting means 41 is not turned on even if the maximum movement amount is operated in the open direction, open direction non-detection error processing (FIG. 8) is performed.

  In this open direction non-detection error process, the drive operation in the open direction of the drive unit 35 is performed again in consideration of the possibility that the first drive operation abnormality in the open direction is due to insufficient torque of the drive unit 35. It is performed at a low speed (S12). If the open state detecting means 41 is not normally turned on even by this low speed driving, the error judging means 106 determines that the book 34 is operating abnormally and the open direction undetected error flag is turned on (S16). Then, a padding operation error display designation command is transmitted to the symbol control board 73 (S17).

  When the screen operation error display designation command is transmitted to the symbol control board 73 side, the special effect symbol display means 31 is first controlled by the error display control means 116 until a predetermined time (for example, 30 seconds) elapses from the reception of the command. A display indicating an operation error of the book 34 is performed on the top.

  When a power-on command is transmitted from the main control board 71 to the effect control board 72 side after the power is turned on to the gaming machine main body 1, a sensor state confirmation process (under the control of the display concealment control means 102 of the effect control board 72 ( FIG. 9) is performed.

  In this sensor state confirmation process, the operation of the open state detecting means 41 is confirmed by operating the pad 34 in the opening direction by the opening operation confirmation process (FIG. 7) similar to the origin return process described above, and then the closing operation confirmation process. (FIG. 10), the screen 34 is moved in the closing direction to confirm the operation of the closed state detecting means 42 (see FIG. 13), and the screen 34 is further moved in the opening direction by the opening operation confirmation process (FIG. 7). The operation of the open state detecting means 41 is confirmed and returned to the origin (see FIG. 12).

  If there is an abnormality in the opening operation confirmation process in this sensor state confirmation process, the open direction non-detection error process (FIG. 8) is performed in the same way as in the origin return process, and there is an abnormality in the closing operation confirmation process. In this case, a closing direction undetected error process (FIG. 11) is performed.

  In this closing direction non-detection error processing, it is very unlikely that the first drive operation abnormality in the closing direction is due to insufficient torque of the driving means 35. The determination means 106 determines that the operation of the pad 34 is abnormal, the closing direction non-detection error flag is turned ON (S42), and the pad operation error display designation command is transmitted to the symbol control board 73 side (S43). A display indicating an operation error of the book 34 is performed on the symbol display means 31 for a predetermined time (for example, 30 seconds).

  Thereafter, it is driven at a low speed until the book 34 is opened. If the drive process in the opening direction is normally performed, the closing direction undetected error flag is ON, but the book 34 is opened. Thus, the display screen 32a becomes visible.

  When the player operates the launch handle 14 during the game, the launching means 13 continuously launches game balls into the game area 23. When the launched game ball falls in the game area 23 and wins the special symbol starting means 26, the special starting opening check processing means 87 requires that the special reserved number is less than the upper limit number (for example, four). In addition, the jackpot determination random number value and jackpot symbol random value acquired by the special random number creation processing means 86 are stored in the special random number storage means 88 in association with the special reserved number at that time.

  When the special symbol display means 62 is variably displayed and one or more jackpot determination random numbers are stored in the special random number storage means (when the number of special hold numbers is one or more), the jackpot determination processing means In step 94, the jackpot determination random number value stored in the special random number storage means 88 is retrieved first, and the jackpot determination random number value is determined based on whether or not the jackpot determination random number value matches a predetermined jackpot determination value. A determination is made.

  Then, based on the determination result, the special stop symbol selection processing means 95 selects either “0” to “9” which is the symbol of the big hit mode or “−” which is the symbol of the off mode as the special stop symbol. Further, the fluctuation pattern selection processing means 96 selects any one of the reach big hit fluctuation patterns A0, A1, the reach-out fluctuation patterns B0, B1, and the non-reach-out fluctuation pattern C. Thereafter, a special symbol variation pattern designation command and a special stop symbol designation command are transmitted to the effect control board 72 side via the control command transmission means 91, and thereafter, corresponding to the variation pattern selected by the variation pattern selection processing means 96. A special symbol stop command is transmitted with the passage of the fluctuation time.

  The special symbol variation pattern designation command, special stop symbol designation command, and special symbol stop command transmitted to the effect control board 72 side are further transferred to the symbol control board 73 side by the control command transmission / reception means 101.

  On the symbol control board 73 side, when the special symbol fluctuation pattern designation command and the special fluctuation stop designation command are received from the main control board 71 side, the production stop symbol selection means 114 based on them receives “7/7/7”. Stop symbol corresponding to jackpots such as “4, 4, 4”, stop symbol corresponding to losing reach such as “7, 5, 7”, etc. Stop corresponding to losing without reach such as “5, 6, 7” Any one of the symbols is selected as a stop symbol of the effect special symbol.

  Then, under the control of the special symbol display control means 112, the special symbol variation display is started on the special symbol display means 62 in accordance with the special symbol variation pattern designated by the special symbol variation pattern designation command. The control means 115 starts the variation display of the effect special symbol based on the effect special symbol variation data read from the effect special symbol variation data storage means 113 corresponding to the special symbol variation pattern.

  Thereafter, based on the reception of the special variation stop designation command from the main control board 71 side, the special symbol is the stop symbol designated by the special stop symbol designation command, and the production special symbol is selected by the production stop symbol selection means 114. Stop and confirm each stop symbol.

  When the variation pattern is the reach jackpot opening / closing variation pattern A1 or the unreachable opening / closing variation pattern B1 that accompanies the opening / closing operation of the notebook 34, the opening / closing scene of the notebook is incorporated in the production special symbol variation data corresponding thereto. In addition, the moving image including the opening / closing scene of the book is displayed on the effect special symbol display means 31.

  On the other hand, when the effect control board 72 side receives a special symbol fluctuation pattern designation command from the main control board 71 side, the fluctuation pattern designated by the command is the reach jackpot opening / closing fluctuation pattern A1 accompanying the opening / closing operation of the notebook 34 or the reach deviation. Corresponding to the normal opening / closing process of the book 34 by the opening / closing control means 105 on the condition that the opening / closing variation pattern B1 and neither the opening direction undetected error flag nor the closing direction undetected error flag is ON. Thus, a process for controlling the driving means 35 to open and close the notebook 34 in accordance with a predetermined opening / closing pattern is performed. As a result, the notebook 34 opens and closes so as to cover the front side of the notebook image 34a on the display screen 32a in synchronization with the opening and closing operation of the notebook displayed on the special effect display unit 31 (see FIG. 14). Therefore, when the notebook 34 is normally opened and closed, the player does not see the notebook image 34 a displayed on the display screen 32 a hidden behind the notebook 34.

  In this normal opening / closing process, a process similar to the closing operation confirmation process (FIG. 10) is performed when the notebook 34 is driven in the closing direction, and a process similar to the opening operation confirmation process (FIG. 7) is performed when the book 34 is driven in the opening direction. Is done. That is, for example, when there is an abnormality during the operation of the book 34 in the closing direction, the closing direction non-detection error process (FIG. 11) is performed, and the error determination means 106 is performed without driving the closing direction again. As a result, the closing direction undetected error flag is turned ON (S42), a padding operation error display designation command is transmitted to the symbol control board 73 side (S43), and a predetermined time (for example, 30 seconds) is displayed on the effect special symbol display means 31. ) A display showing an operation error of the book 34 is performed.

  Thereafter, the book 34 is driven at a low speed until it is in the open state. When the drive process in the opening direction is normally performed, the closing direction undetected error flag is ON, but the book 34 is in the open state. The display screen 32a becomes visible.

  On the other hand, for example, when there is an abnormality during the operation of the book 34 in the opening direction, an opening direction non-detection error process (FIG. 8) is performed. That is, the drive operation in the opening direction of the drive means 35 is performed again at a low speed (S12), and the open direction non-detection error flag is set when the open state detection means 41 is not normally turned on even by the low speed drive. Turned ON (S16), a padding operation error display designation command is transmitted to the symbol control board 73 (S17), and a display showing the operation error of the padding 34 is performed on the effect special symbol display means 31 for a predetermined time (for example, 30 seconds). Is called.

  When an abnormal operation of the book 34 is detected in the origin return process or sensor state confirmation process performed after power-on, or the subsequent normal opening / closing process, and the open direction undetected error flag or the close direction undetected error flag is turned ON. Is displayed on the special effect symbol display means 31 at a predetermined timing, and the normal opening / closing process of the book 34 by the opening / closing control means 105 is not performed, but the other game operations remain as they are. Will continue.

  Therefore, for example, when the reach big hit opening / closing fluctuation pattern A1 or the reach-off opening / closing fluctuation pattern B1 accompanied by the opening / closing operation of the book 34 is selected by the special stop symbol selection processing means 95 thereafter, the effect control board 72 and the symbol control board 73 are selected. A special symbol variation pattern designation command or the like corresponding to these variation patterns A1 and B1 is transmitted to the side, and the special symbol and the effect special symbol are variably displayed as usual without the opening / closing operation of the notebook 34 being performed.

  Even in such a case, in the pachinko machine according to the present embodiment, since the opening / closing scene of the padding similar to the opening / closing operation of the padding 34 is displayed as a moving image on the effect special symbol display means 31, at least the padding 34 displays the display screen 32a. When the player is stopped in an open state, the information that the player can recognize regarding the change in the special effect design is substantially the same as when the notebook 34 is operating normally, and until the error is released. The game can be continued without any discomfort.

  When the error state is canceled and the power is turned on again, the open direction non-detection error flag and the close direction non-detection error flag are reset, and the normal game is resumed.

  As described above, in the pachinko machine of the present embodiment, the special effect symbol display control means 115 displays the special effect symbol display in synchronization with the opening / closing operation of the concealment means 34 under the control of the opening / closing control means 105 based on the opening / closing command. Since the moving image of the opening / closing operation by the concealing unit 34 is displayed on the unit 31, even when the concealing unit 34 is abnormal and becomes inoperable, at least the concealing unit 34 opens the display screen 32 a. When stopped in the state, the information that the player can recognize regarding the variation of the special effect design is substantially the same as when the concealing means 34 is operating normally, and remains until the error is released. You can continue playing without a sense of incongruity. That is, there is an advantage that even if an operation abnormality occurs in the concealing means 34, the progress of the game is not hindered as much as possible.

  An error determination means 106 for determining an operation abnormality of the concealing means 34 is provided, and the opening / closing control means 105 is concealed even if an opening / closing command is issued when the error determination means 106 determines an operation abnormality of the concealing means 34. Since the configuration is such that the opening / closing operation 34 is not performed, a new problem or the like due to an excessive load on the driving means 35 can be prevented.

  An open state detecting means 41 for detecting that the concealing means 34 is in an open state is provided, and the error determining means 106 is controlled by the open state detecting means 41 in spite of reaching the maximum operation amount in the opening operation of the concealing means 34. Since it is configured to determine that the operation is abnormal on the condition that the open state is not detected, it is possible to reliably detect the operation abnormality in the opening direction of the concealing unit 34 with simple control.

  The concealing means 34 is constituted by a paddle that is suspended from the front side of the display screen 32a and winds up the upper end side thereof and is held so as to be able to be fed out. The opening / closing control means 105 is the maximum in the opening operation of the concealing means 34. If the open state is not detected by the open state detection means 41 even though the operation amount has been reached, the concealing means 34 is further operated in the open direction at a low speed, and the error determination means 106 has the maximum open operation amount. However, when the open state detecting means 41 does not detect the open state, it is determined that the operation is abnormal. Therefore, the opening operation cannot be normally performed due to insufficient torque of the driving means 35. In some cases, normal operation can be performed with high probability, and smooth game progress can be achieved with as few error judgments as possible.

  Closed state detecting means 42 for detecting that the concealing means 34 is in the closed state is provided, and the error determining means 106 is detected by the closed state detecting means 42 in spite of reaching the maximum operation amount in the closing operation of the concealing means 34. Since it is configured to determine that the operation is abnormal on the condition that the closed state is not detected, it is possible to reliably detect the operation abnormality in the closing direction of the concealing unit 34 with simple control.

  The opening / closing control means 105 is configured to operate the concealment means 34 in the opening direction when the error determination means 106 determines that the operation is abnormal on the condition that the closed state is not detected by the closed state detection means 42. Even if an operation abnormality in the closing direction of the concealing means 34 occurs, if there is no abnormality in the operation in the opening direction, the concealing means 34 is opened and the display screen 32a is made visible so that the game remains as it is. Can continue.

  The concealing means 34 is composed of a notebook that is suspended on the front side of the display screen 32a and winds up the upper end side thereof and is held so as to be able to be fed out. When the concealing means 34 is closed, its maximum operation amount is reached. Nevertheless, when the closed state is not detected by the closed state detecting unit 42, the error determining unit 106 is configured to determine that the operation is abnormal at that time, and therefore the torque of the driving unit 35 may be insufficient. In the case of an abnormal operation in the closing direction with very little possibility, there is an advantage that an error can be determined quickly and a new abnormality due to the reverse winding of the concealing means 34 can be prevented.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to this embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the concealing means 34 is not limited to a paddle that winds and lowers on the upper side of the display screen 32a, and may be anything such as a curtain or sliding door that opens and closes to the left and right.

  In the embodiment, when the reach jackpot opening / closing fluctuation pattern A1 and the reach-off opening / closing fluctuation pattern B1 accompanied by the opening / closing operation of the book 34 are selected, the animation of the opening / closing scene of the book is always displayed on the effect special symbol display means 31 correspondingly. Is displayed, but, for example, only when the opening / closing operation of the notebook 34 is not performed by the opening / closing control means 105 due to an abnormal operation of the notebook 34, the special effect design using the variation data including the opening / closing scene of the notebook is used. The change display may be performed.

  In this case, the effect special symbol display control means 115 may switch to the effect special symbol change display using the change data including the opening / closing scene of the note on the basis of, for example, receiving the note operation error display designation command. Good.

  As a special symbol variation pattern, in addition to the variation pattern A1 or the like that actually operates the notebook 34, the variation pattern A1a or the like that displays the opening / closing scene of the notebook on the production special symbol display means 31 without moving the notebook 34 or the like. It may be provided. In that case, the jackpot reliability or the like may be different between the two variation patterns. When such a configuration is adopted, if an error display is performed when a padding operation error display designation command is received as in the embodiment, even if an operation abnormality has occurred in the concealing means 34, the player Can distinguish the variation patterns A1 and the like from A1a and the like, and can recognize the difference in the jackpot reliability.

  You may comprise the concealing means 34 so that it can be manually opened from the back side of the front frame 3, for example. With this configuration, even when an abnormality that cannot be easily recovered, such as a failure of the drive means 35, the hall clerk manually opens the concealing means 34 and the player directs the special special symbol display means 31. The game can be continued by making the display screen 32a visible.

  The configuration of the control system, for example, the configuration of each control board is arbitrary. For example, the special symbol display control means 112 may be provided on the main control board 71 side.

  The present invention is not limited to pachinko machines, and can be implemented in various game machines such as slot machines as well as various ball game machines such as arrange ball machines and sparrow ball game machines.
