The left side is a view of the working state seen from the side, and the right side is a view seen from the top. In this state, the viewpoint of the worker HM is about the front of the upper speaker 4b, so that the display device 9 can be viewed from the front. FIG. 5B is a diagram showing a state in which the front door 2 of the slot machine A is largely opened (second opening angle Y degree) and the work is performed while standing between the front door 2 and the housing 1. In this state, the viewpoint of the worker HM is between the liquid crystal driver board case 39 and the main board case 23. When the front door 2 side is seen in this state, the state shown in FIG. . At this time, the viewpoint of the worker HM substantially coincides with the position of the operation portion of the main board case 23 when the front door 2 is closed. In the slot machine A, the size and position of the window portion 7 are set so that the display device 9 can be viewed from this viewpoint. That is, it is preferable that the window portion (transparent portion) is provided in a region corresponding to a line connecting the arrangement position of the operating means of the main substrate case, particularly the main substrate case, and the upper side portion of the display 9.

  Next, the configuration of the opening angle detection mechanism 22 will be described. FIG. 6A is a cross-sectional view of the shaft 20a cut in the horizontal direction with the front door 2 attached to the housing 1. FIG. A part 2 ′ of the front door 2 is provided with a fitting part for fitting the shaft 20 a and the blade 21. FIG. 6B is a perspective view of the opening angle detection mechanism portion from the front side of the housing. A lower portion of the shaft 20a is normally hidden behind a support bracket of the shaft 20a, but is provided with a first gear portion 44, which is configured as one member with the shaft 20a. A second gear portion 46 is provided on the housing side via a support shaft 45. By the first link portion including the first gear portion 44 and the second gear portion 46, the horizontal rotation due to the opening of the front door 2 is converted into the vertical rotation.

  As shown in FIG. 6C, a third gear portion 47 is provided adjacent to the second gear portion 46. FIG. 6C is a view of the mechanism of FIG. 6B viewed from the Z direction. The second gear portion 46 and the third gear portion 47 are configured as one member, and the third gear portion 47 is rotated by the rotation of the second gear portion 46. The third gear portion 47 is provided so as to engage with the rack 48, and the rack 48 is movable on the track 48 '. The second link portion formed by the third gear portion 47 and the rack 48 converts vertical rotation into vertical movement.

  With the configuration of the first link portion and the second link portion, the horizontal rotation due to the opening of the front door 2 is converted into a vertical movement operation. That is, when the front door 2 is gradually brought close to the open state from the closed state, the shaft 20a and the first gear portion 44 rotate in the direction P. This rotation is transmitted as rotation of the second gear portion 46 in the Q direction by the action of the first link portion. As the second gear portion 46 rotates, the third gear portion also rotates in the Q direction. This rotation is transmitted as movement of the rack 48 in the R direction by the action of the second link portion.

  On the track of the rack 48, an engaging claw 50 biased by a biasing means such as a spring 49 is provided, and the engaging claw 50 is in contact with the rack 48. The rack 48 is provided with a first notch 51a at a position in contact with the engaging claw 50 in the state of the opening angle X shown in FIG. The engagement claw 50 is fitted into the portion 51a so that the movement of the rack 48 is temporarily fixed. By this temporary fixing, the rotation of the shaft 20a is fixed, and the front door is temporarily fixed at the opening angle X. This temporary fixing is released by further moving the door in the opening direction.

  Further, a second notch 51b is provided at a position in contact with the engaging claw 50 in the state of the opening angle Y shown in FIG. The engaging claw 50 is fitted and the movement of the rack 48 is temporarily fixed. By this temporary fixing, the front door is temporarily fixed at the opening angle Y as described above. The biasing means such as the spring 49, the engaging claw 50, and the notch 51 (51a, 51b) serve as an opening restricting means for restricting movement of the front door 2 in the opening direction at a predetermined position. . Due to the function of the opening restriction means, it is not necessary to support the front door 2 with an arm or the like by temporarily fixing the front door 2 during work, thereby improving work efficiency.

  Further, as shown in FIG. 6 (c), on the track 48 ', a first opening angle sensor 52 comprising a light projecting part 52a and a light receiving part 52b, and a first light emitting part 53a and a light receiving part 53b are also provided. Two open angle sensors 53 are provided. When the rack 48 moves to a predetermined position, these sensors enter the light receiving part and turn on when the light from the light projecting part reflects to one side of the rack 48 as shown by the dotted line. It is. The first opening angle sensor 52 is turned on when the light from the light projecting unit 52a enters 52b at one end of the rack 48 when the opening angle X is in the state shown in FIG. With this configuration, it is possible to detect that the opening angle has reached X. Similarly, the second opening angle sensor 53 senses that the opening angle has reached Y. The first opening angle sensor 52 and the second opening angle sensor 53 function as an opening angle detection unit that detects the opening angle of the front door 2. The opening angle detection mechanism 22 detects the opening angle in a state where the opening angle is temporarily fixed in the state of X and Y by the action of the opening restricting means and the opening angle detecting means. It is possible to reliably detect that Y has been reached.

  The first opening angle X described above is preferably an angle that allows the operator to insert the arm with a margin, that is, an angle having a gap of about 15 cm between the housing 1 and the front door 2. Since the width of the slot machine is about 45 cm, the actual angle is preferably about 20 to 30 degrees. On the other hand, the second opening angle Y is preferably set to an angle that allows the operator's shoulder width to enter with a margin, that is, an angle having a gap of about 50 cm between the housing 1 and the front door 2. The actual angle is preferably about 60 to 100 degrees.

  FIG. 7 is a diagram showing an electrical block configuration of the slot machine A. The control unit 100 of the slot machine A includes a main control unit 101, a first sub control unit 102, and a second sub control unit 103.

The CPU 105 functions as a setting value change execution unit 108 that changes a probability setting value, which will be described later, and a display mode change unit 109 that performs change control for changing the mode of displaying the setting value. Further, the CPU 105 includes a random number generator capable of generating a random number value (0 to 65535), and also functions as a lottery means 110 for performing a lottery during a game using this random number.

  The ROM 106 of the main control unit 101 includes a lottery table storage unit 111 that stores a lottery table in which a random value and a result of success / failure are associated with each other for use in the lottery by the CPU 105 described above. The lottery table storage unit includes a plurality of tables having the same random number value but different results, and stores them as probability setting values. In this embodiment, the lottery table storage unit 111 stores six lottery tables, which can be switched as set values. This lottery table will be described later.

  In addition, the ROM 106 also displays a setting value change program 112 for switching the above setting values, a display mode determination program 113 for controlling the display mode of the setting values, and abnormalities occurring in various places of the gaming machine. An abnormal information display program 114 for performing the above is provided. Further, although not shown, a stop data table for determining the stop position of the reel is also provided.

  The RAM 107 of the main control unit temporarily stores a setting value temporary storage unit 115 for temporarily storing a setting value before being confirmed in the middle of the change, a display state flag such as a setting value, and the like. Display mode temporary storage unit 116, a credit number storage unit 117 for electronically storing the number of inserted medals, and the like.

  A signal from the operation unit 119 is input to the main control unit 101 via the interface 118. The operation unit 119 is a part operated by the player during the game, and signals from this part are collected on the door relay board 41 provided on the front door side shown in FIG. Sent to the main control unit 101 via 42. The operation unit 119 includes the stop switches 12a to 12c, the betting number setting switch 8, and the start switch 11 described above. Similarly, a signal from a medal detection sensor 120 installed in a medal sorting device (not shown) for detecting and sorting medals inserted from the medal slot 10 is also input to the main control unit 101. In response to this signal, the stored number of credits in the credit number storage unit 117 is updated. The start switch 11 is also used as a confirming operation means for confirming a set value when a set value to be described later is changed.

  In addition, a signal from a setting change unit 121 including a key switch 26 and a setting change switch 27 provided on the main board is input to the main control unit 101 via an interface 118. The main control unit receives the signals from these and changes the set values. Further, a signal from the front door opening detection unit 122 including the front door opening sensor SW, the first opening angle detection sensor 52, and the second opening angle detection sensor 53 is also input to the main control unit 101 via the interface 118. It has become.

  Further, signals from the stop selection switch 28a, the settlement selection switch 28b, and the door opening sensor 29 provided on the main board are also input via the interface 118.

  The main control unit 101 drives the display unit 9, the reel drive unit 124, the payout device 37, the door opening notification device 125, the abnormality notification lamp 126, and the like via the driver circuit 123. As described above, the display unit 9 displays the number of credits during the game, but the setting value is displayed in the setting change mode. In addition, the display 9 displays information on the abnormality that has occurred in each part of the gaming machine as an error, and when an abnormality occurs, it takes priority over the display of the number of credits and the set value. Thus, the main control unit controls the error code to be displayed. A drive signal to the display device 9 is transmitted from the connection terminal portion 42 shown in FIG.

  The reel driving unit 124 includes a left reel driving unit 124a, a middle reel driving unit 124b, and a right reel driving unit 124c that are provided corresponding to the reels 6a to 6c, respectively. Each of the reel driving units 124a to 124c has a stepping motor, and rotates the reel according to the operation of the start switch, and displays a predetermined symbol on the reel on the window unit 7 according to the operation of the stop switch. The stepping motor is driven so as to stop in the state. The door portion opening alarm 125 is for notifying that the door portion 25 provided on the main board 23 is open, and is composed of an LED or the like. With this door part opening alarm 125, forgetting to tighten the door part 25 can be prevented. The abnormality notification lamp 126 is made up of an LED or the like, and is used to notify a control abnormality or a gaming state abnormality that has occurred in the gaming machine.

  The first sub-control unit 102 is connected to the main control unit 101 via the relay board 104 and receives the signal from the main control unit 101 and controls the effect display device 3 and the like. The first sub-control unit 102 includes a CPU 127 that controls the overall operation of the first sub-control unit 102, a ROM 128 that stores effect data and the like, a RAM 129 that temporarily stores the state of the effect being executed, and the like. The effect display device 3 is connected to the first sub-control unit 102 via a driver circuit 130, and the effect display device 3 receives the drive signal from the first sub-control unit 102 and displays it on the liquid crystal. Control is performed so that the frames are read sequentially. By this control, an effect display related to the lottery result of the main control unit is performed.

  The second sub-control unit 103 is connected to the main control unit 101 via the relay board 104 and the first sub-control unit 102, and receives signals from the main control unit 101 and controls speakers, lamps, and the like. It has a function. The second sub-control unit 103 includes a CPU 131 that controls the overall operation of the second sub-control unit 103, a ROM 132 that stores effect data and the like, a RAM 133 that temporarily stores the state of the effect being executed, and the like. The second sub-control unit 103 is connected to the upper speaker 4, the lower speaker 17, the effect lamp 135 and the like via a driver circuit 134, and the second sub-control unit 103 performs these effects by driving them. .

  Next, the operation of the slot machine A during the game will be described below. FIG. 8 is a flowchart showing the control of the main control unit during the normal game.

  First, when a game is started, a bet number setting process is performed in step S100. When the bet number is not set, the operation of the start switch is not effective. When a medal is newly inserted from a state where the bet number is not set, this medal is detected by the medal sensor 120, and up to three inserted medals are automatically set as the bet number. Further, when the re-gamer wins in the previous game, the bet number is automatically set, so the bet number setting process is not performed. In cases other than the above, when the player presses the betting number setting switch 8, the number of medals operated from the credit number storage unit is subtracted, and this number is set as the betting number. Then, the remaining credit number is displayed on the display unit 9. At the same time, the winning line corresponding to the number of bets is activated, and that effect is displayed on the activated line display. The bet number can be changed until the start switch is operated.

  In step S101, the operation of the start switch 11 is waited. When the start switch 11 is operated, a lottery process in step S102 and a reel rotation process in step S103 are performed. In the lottery process of step S102, a random number generated by a random number generator included in the CPU of the main control unit is extracted at the operation timing of the start switch 11, and a lottery table stored in the lottery table storage unit 111 of the ROM of the main control unit. This is a process for determining whether or not it is correct. Which lottery table is used as the lottery table differs depending on the value in the set value temporary storage unit 115. The lottery result determined based on the lottery table includes a small role for paying out a predetermined number of medals, a re-gamer that can execute the next game without inserting a new game medium, and a predetermined game from the next game. A bonus combination for starting a bonus game that increases the winning probability of several small combinations, and a loss are included. And according to each combination, the symbol combination arranged on an effective line is defined. In the following description, the determination of each combination by lottery will be referred to as “winning”, and the combination of symbols according to the combination on a predetermined effective line will be referred to as “winning”.

  The reel rotation process in step S103 is a process of rotating the reels 6a to 6c by transmitting a drive signal to the reel drive unit 124. By this reel rotation processing, the stop switch operation becomes effective after the rotation speed of the reel becomes constant.

  Subsequently, in step S104, it is detected whether or not the stop switch 12 has been operated. When the operation is performed, stop control processing for stopping the corresponding reel is performed in step S105. This stop control process refers to the reel stop table stored in the ROM 106 based on the stop operation position that is the position where the stop operation has been performed for each reel and the result determined in the lottery process described above. This is performed by stopping the rotation of the reel at a position (hereinafter referred to as a reel stop position). The reel stop position is determined so that the reel stops within a predetermined number of symbols, in this case within 4 frames, as viewed from the stop operation position. When there is a symbol corresponding to the lottery result within 4 frames from the stop operation position, this symbol is arranged on the effective line. In this stop control process, the priorities of the combinations arranged on the active line are performed in the order of replay, bonus, and small combination. When the re-gamer is elected, the re-gamer is controlled to be aligned on the active line. If a bonus flag is established and a small role is won at the same time due to a lottery win or a bonus carry-over described later, the bonuses are controlled to be preferentially aligned. However, it is limited to the case where it can be stopped within 4 frames.

  Next, in step S106, it is determined whether all the reels 6a to 6c are stopped. If NO, the process returns to step S104 and the stop control process is performed. If all reels are stopped, it is determined in step S107 whether or not the winning symbol is on the active line. If YES, the winning combination is determined in step S108. If the winning combination is a small combination, the payout device 37 is driven to pay out a predetermined number of medals. On the other hand, if the winning combination is a re-game player, an automatic bet number setting process for automatically resetting the bet number set in the current game as the bet number in the next game is performed in step S112. In this case, since the number of credits is not subtracted from the credit, it is possible to play the next game without inserting a new game medium (including the consumption of credit). In this case, since the betting number setting process for the next game is automatically performed, the betting number setting process is not performed for the next game. If the winning combination is a bonus, the bonus game mode is set, and the next game is shifted to the bonus game.

  If the determination in step S107 is NO, it is determined if the bonus is won by lottery in step S110, that is, if the bonus is won by lottery but is not aligned on the effective line as a result of stop control. If YES, carryover processing is performed in step S111. This carry-over process is performed by storing the establishment of the bonus flag in the RAM of the main control unit. In a game in which the bonus flag is established, the number of established bonus flags is not added even if a bonus is won. The memorization of the bonus flag is continued until the bonus combination is won. In the present embodiment, a case where a plurality of bonus flags are not established is shown, but this is not limiting, and a plurality of flags are accumulated by winning a bonus when the bonus flag is established. The winning combination of the corresponding bonus combination may be avoided by the stop control until a predetermined condition is established during the game, for example, the winning of a specific small combination.

  The bonus game mode is a mode in which the random number width corresponding to the small combination is changed by changing the lottery table used in step S102. As a result of this change, the winning probability of a small role by lottery has increased to about 10 times. Further, during this mode, the bonus combination lottery is not performed or even if it is won, it is invalidated. As described above, this bonus game is an advantageous state for a player who can win a large amount of medals because a small role is frequently won.

  Next, processing during the bonus game will be described with reference to FIG. Since the processing from step S113 to step S119 is the same as the processing from step S100 to step 106 in FIG. 8, the description thereof is omitted here. If the determination in step 119 is YES, it is determined in step 120 whether or not a winning according to the lottery has been established on the active line. If there is no winning combination, the process returns to step S113 to play the next game. If there is a win, the winning combination is determined in step 121. If the game is replayed, an automatic betting number setting process is performed in step S122, and the process returns to step S113 to play the next game. In the case of a small role, the payout device 37 is driven in step 123 to pay out a corresponding number of medals, and in step 124, it is determined whether or not the bonus game has ended. This bonus game is terminated when the added value of the number of payouts reaches a certain number, for example, 345. For this reason, every time a small role is established, the payout number is counted in the RAM of the main control unit, and when the predetermined number is reached, the bonus game is canceled and the game returns to the normal game. As a bonus game, for example, a plurality of BB1 payouts of 345, 125 BB2, etc. are provided. In addition, here, an example is shown in which the normal game is returned immediately after the bonus game is ended. However, after the bonus game is ended, a predetermined number of replay times (hereinafter referred to as RT games) are performed, and then the normal game is returned. Also good. Further, the bonus game may be terminated by other conditions, such as a specific small role being established a predetermined number of times, instead of a predetermined number of payouts being reached. Further, the type of bonus may be one type or three or more types.

  The RT game is a game in which an RT game mode is set in which the probability that a replay is won by lottery is increased by switching the random number width of the lottery table. The replay probability is set to about 1 / 7.3 in the normal game, but increases to about 1 / 1.3 in the RT game. In this case, the probabilities of the combinations, bonuses, and small combinations other than the replay do not change, but the random number range allocated to the out-of-game is allocated to the replay. In addition, the trigger for starting the RT game may not be after the end of the bonus game, but may be when a specific small role is won during the normal game. During this RT game, a replay is won with a high probability, so it is possible to expect a bonus win with a small amount of medal consumption.

  In addition, the slot machine A has six types of lottery tables (settings) as lottery tables used during the normal game. FIG. 10 shows a part of the lottery table. In this table, the probability of a lottery winning by assigning a random value is schematically shown. The vertical column of the table represents each setting, and the horizontal column represents the probability of winning in each setting. The setting values represented by 1 to 6 are generally called setting values. As is apparent from the table, the probability of the bonus (BB1, BB2) is different for each set value. The probability of BB1 is 1/596 in setting 1, whereas it is as high as 1/345 in setting 6. For this reason, the probability of becoming a bonus game state in which a large number of medals are paid out differs for each set value. In addition, when a small combination such as small combination 2 having a different probability for each set value is used as an RT game entry combination, the probability of becoming an RT game mode varies for each set value. For this reason, the store side sets the set value of each unit in view of the operating profit and the game table with customers.

  In the embodiments described above and below, as the setting values, those with different bonus winning probabilities between the setting values are shown, but the present invention is not limited thereto, and the setting values As long as the probability of being in an advantageous state with respect to the acquisition of game media is different. As this advantageous state, in addition to the bonus game state described above, a replay high probability state such as an RT game, an AT game in which a winning combination or a stop operation order is notified, and the like can be exemplified. Moreover, as an advantageous state, it may straddle a plurality of games or may be an advantageous state that ends in one game. That is, as long as the probability of a bonus game state, a replay high probability state, a role that triggers entry into an AT game or the like, or a probability that a predetermined game medium is paid out varies between set values, It is included in the concept.

  Next, the setting value changing operation will be described. FIG. 11 is a flowchart showing the control of the main control unit during a setting value changing operation. First, in step S200, it is confirmed whether or not the setting change mode is set. The transition from the normal mode to the setting change mode is performed by turning on the power again with the key switch 26 on the main board rotated to the right. In step S200, it is confirmed whether or not the key switch is turned in the power-on state. If YES, the process proceeds to the setting change mode. In step S201, it is confirmed whether a display prohibition state is set. And it waits, without displaying on the indicator 9, until a display prohibition state is cancelled | released. If the display prohibition state is cancelled, the display mode is read in step S202, and the setting value display process is performed in step S203. The display mode in the normal display state of each set value 1 to 6 is displayed on the display 9 in a mode as shown in FIG.

  When the setting change switch 27 is operated in step S204, if the current setting value is 6 in step S205, the setting value is changed to 1 in step 206. If the value is other than 6, the set value is incremented by 1 in step S207. For example, when the setting value is 4, the setting value is changed to 5. In step S208, the display of the set value displayed on the display unit 9 is updated to the changed value. That is, the main control unit 101 sequentially displays the setting values 1 to 6 in FIG. 12 by switching on / off the segments. These changes are performed by a setting value changing program in the ROM 106. Steps 204 to S208 are performed every time the setting change switch 27 is operated. When the start switch 11 is operated in step S209, the changed set value is confirmed, and the setting value is stored in the set value temporary storage unit 115 of the RAM 107. The operation of the setting change switch 27 is effectively accepted until the start switch 11 is operated. Thereafter, the key switch 26 is turned to the left and returned to the original position to return to the normal mode. The display of these set values is difficult to confirm when the display 9 is viewed upside down. In particular, it is further difficult under the situation where the setting change switch 27 is operated to continuously change the setting value. Therefore, in the present invention, reverse display control as described later is performed.

  Subsequently, the setting of the display mode performed by the main control unit when displaying the set value on the display 9 will be described below.

  FIG. 13 is a flowchart showing flag processing related to the display mode on the display unit 9 performed by the main control unit using the display mode determination program in the ROM 113 and the display mode temporary storage unit in the RAM 116.

  First, in step S300, it is confirmed whether or not the front door 2 is opened based on a signal from the front door opening sensor SW. If YES, 0 is set as the value of the display permission flag F0 in step S301. The display permission flag F0 is such that setting value display is not permitted when the value is 0, and setting value display is permitted when the value is 1. And it waits for the 1st opening angle detection sensor 52 to turn on by step S302. If NO, timing is started, and if a predetermined time has elapsed with the value of F0 being 0 in step S303, an abnormality notification process in step S304 is performed. This abnormality notification process is performed by the abnormality notification lamp 126, the upper speaker 4, the lower speaker 17, and the like. This abnormality notification process is due to the fact that the door opening angle is continuously maintained for a predetermined time in a state of X degrees or less. In this state, there is a high possibility that an illegal act by opening a door inconspicuously and allowing a foreign object to enter through the gap, so that this state has continued for a predetermined time, for example, 20 to 30 seconds. It is determined that there is an abnormality and is notified.

  If the determination in step S302 is YES, a process of rewriting the value of the display permission flag F0 to 1 is performed in step S305. At the same time, 0 is set as the value of the display reverse flag F1 in step S306. The display reverse flag F1 is for setting the reverse display mode as the display mode of the display 9. When the value is 0, the normal display mode is set, and when the value is 1, the reverse display mode is set. Then, when it is determined in step S307 that the second opening angle sensor 53 is turned on thereafter, it is determined that the opening angle has reached Y degrees, and the value of the display reverse flag F1 is set to 1 in step S308. To.

  FIG. 14 shows a display mode setting process performed by the main control unit using the display mode determination program stored in the ROM 113 and the display mode temporary storage unit stored in the RAM 116, which is subjected to the flag processing described above.

  First, in step S400, the state of the display permission flag F0 is confirmed. If it is 0, the display prohibited state is set in step S401. In this display prohibited state, the set value is not displayed on the display unit 9. Accordingly, when an action is taken to open the front door 2 slightly and operate the setting change switch or the like to change the setting value illegally, the current setting value cannot be visually recognized. These actions cannot be prevented. If the value of F0 is 1, the determination in step S400 is NO, and then the state of the display reverse flag F1 is confirmed in step S402. When the value of F1 is 0, the normal display mode is set in step S403, and the normal set value display shown in FIG. 12 is performed. When the value of F1 is 1, the determination in step 402 is NO, and the reverse display mode is set in step S404. By reading the display mode set by these processes in step S202 of FIG. 11, the set value according to the display mode is displayed.

  FIG. 15 shows a set value display displayed on the display 9 in the reverse display mode. As shown in the figure, the setting values 1 to 6 are displayed in the same manner as the display mode of FIG. When working in the working state shown in FIG. 5B, that is, in the state of the opening angle Y or more, the display device 9 is viewed upside down, so the set value is displayed in the state of FIG. When the display of the set value 6 is viewed in this state, it becomes as shown in FIG. 16 and it can be easily confirmed that the set value is 6. For this reason, even when the front door 2 is largely opened and the setting change switch is operated in the housing, the change display for sequentially changing the setting values of the display 9 can be easily confirmed. There is no need to check from the front of the door, and workability is improved.

  Further, the slot machine A has a function of displaying an abnormality of the gaming machine that has occurred during the game or during maintenance work as a code display on the display unit 9. FIG. 17 shows the type and code of abnormality information displayed on the display 9 and the display state on the display 9. The slot machine A monitors the state of each part in units of CPU interrupt of the main control unit 101, and has a function of detecting an abnormality described below. The display of the code information is performed by an abnormality information display program 114 provided in the ROM 106 of the main control unit.

  The code “CJ” indicates “selector medal clogging” in which the medal is jammed in the medal sorting device, and is determined by the medal remaining in the medal detection sensor unit of the medal sorting device for a predetermined time or more. The code “Cr” is caused by “medal passage abnormality at the time of insertion” which is determined by the medal detection sensor to be abnormal when the medal is inserted. Possible failure. The code “CC” is caused by “medal passage abnormality when insertion is not possible” which is determined by the medal detection sensor to be abnormal when the medal cannot be inserted. A sensor failure is considered.

  The code “HE” indicates “medal shortage” in which medals to be paid out by the payout device 37 are insufficient, and is due to the lack of medals in the medal storage device 36. The code “HJ” indicates “payout device medal jamming” in which medals are jammed at the payout port of the payout device 37. The code “HC” indicates “payout sensor abnormality” in which the state of the payout sensor provided for confirming that a predetermined number of medals have been paid out at the payout port of the payout device has become abnormal. It is determined when the detection of the payout sensor signal less than the time width is detected a predetermined number of times. Possible causes are fraudulent behavior or failure of the payout sensor. The code “HA” indicates “payout device abnormality” in which the state of the payout device 37 is abnormal, and is determined by a medal being paid out when the medal payout device drive power is OFF. . Possible causes are fraudulent behavior or failure of the payout sensor.

The code “FL” indicates “auxiliary medal storage container full” in which the auxiliary medal storage container 38 is full. The code “AE” indicates “program abnormality”. When a combination of symbols different from the lottery result stops on the active line, the number of cards inserted when the start switch operation is accepted is abnormal (for example, three bets). This is determined when the set value becomes abnormal when the power is turned on (when the number of models accepting the number is 4). These causes may be failure of each part or fraud. The abnormality information is displayed on the display unit 9 as shown in FIG. This display is given priority over both the case where the number of credits during the game is displayed and the case where the set value is displayed during the setting change. In the case of these abnormalities, the program progress of the gaming machine is immediately stopped together with the abnormality display, or the program progress of the gaming machine is stopped after the game currently in progress.

  Among the abnormalities indicated by the various codes, for the abnormalities other than the code “AE”, after the cause of the abnormality is eliminated, the lock device 14 is rotated to the left by the key or the setting change switch 27 is operated. , Can return to normal state. The code “AE” can be restored by turning the power OFF / ON while the setting change switch 27 is operated, or by changing the mode to the one-time setting change mode and performing the setting determination operation again. In order to eliminate many of these abnormalities, it is necessary to operate the housing 1 with the front door 2 opened. In addition, since these abnormalities do not always occur independently, it is necessary to check whether or not each abnormal state has been resolved while visually confirming the display device 9 even during the operation state for returning to the normal state. That is, the work is performed while viewing the display 9 in the state of FIG.

  From the above point of view, in the slot machine A, even when these abnormal information are displayed as codes, the code information displayed on the display unit 9 is turned upside down by performing the same control as the control in the set value display described above. Display mode. FIG. 18 shows a code display of the abnormality information in the reverse display mode. The meaning of each display mode is the same as that in FIG. 17, but the mode is different. When the display mode is rotated 180 degrees, the display mode is almost the same as that in FIG.

  With this control, even if the display 9 has to be visually recognized in the upside down manner in the work state of FIG. 5B, the display is changed to the state of FIG. 18 in these states. Therefore, it is possible to clearly know which abnormal state has been canceled, and work efficiency is improved.

  Further, in the code display of the set value and the abnormality information, as shown in FIG. 19, it may be distinguished whether the normal display or the reverse display is performed by lighting the dot SD. This control makes it possible to clearly recognize the current set value or the currently occurring abnormality and further improve the work efficiency. In the above, the abnormalities related to the internal control state of gaming machines such as slot machines are listed. It is good also as a structure which displays a code | cord | chord also as a connection state. The inter-machine is electrically connected to the slot machine, accepts valuable values such as money, banknotes, prepaid cards, etc., and pays out medals corresponding to this valuable value through the dispensing device 37 of the slot machine. It has become. Further, when the inter-machine and the slot machine are not connected, the slot machine is controlled so that the game cannot be progressed. According to these configurations, when the game cannot proceed due to poor connection or the like, the abnormality can be quickly identified and resolved, which is beneficial for business.

  The control executed in the first embodiment described above is performed based on a program stored in a ROM as a storage medium mounted on the main control unit. The CPU, ROM, and RAM of the main control unit are mounted on the main control board as a one-chip microcomputer formed in a chip shape.

  According to the first embodiment described above, the probability setting value is displayed or the abnormality information is displayed while sharing the display on the game medium during the game. Thereby, there is no need to provide a dedicated display for displaying the probability setting value or the abnormality information or to provide a plurality of displays. As a result, the cost of the gaming machine main body can be reduced, illegal acts can be effectively prevented, and the work efficiency when the set value is changed or when the abnormality is canceled can be improved.

  Further, according to the first embodiment described above, the configuration in which the detection of the opening angle is performed by the detection means for detecting two fixed angles is shown. However, the detection angle of the detection means can be set in a plurality of stages or continuously. It may be adjustable to any value.

  According to this configuration, since the detection angle can be adjusted to an optimum angle for work on the store side, a gaming machine with higher workability can be obtained. Moreover, it is preferable that not only the detection angle of the detection means but also the angle at which the front door is temporarily fixed can be adjusted simultaneously.

  In the first embodiment described above, an example in which both the first opening angle detection sensor 52 and the second opening angle detection sensor 53 are installed has been described, but instead, only the first opening angle detection sensor 52 is installed. It is good. In this case, information such as a set value is not displayed until the first opening angle. This makes it possible to prevent fraudulent acts that are performed by slightly opening the front door 2. In addition, the configuration in which the set value display is not displayed by the opening angle is not limited to the configuration in which the set value display and the display relating to the number of game media are combined, but also when a dedicated set value display is provided. The same effect can be achieved.

  Further, only the second opening angle sensor 53 may be installed. In this case, since the second opening angle Y is detected to change the mode of the display device 9, the state of the display device 9 can be easily confirmed during the operation, and the work efficiency is improved. The control of the main control unit described above serves as display control means for controlling the display state of the display 9. Further, the present invention is not limited to each configuration as described above, and when the control method by the display control means is applied, as described above, there is an effect of improving workability.

  Next, a second embodiment according to the present invention will be described.

  FIG. 20 shows a slot machine A ′ according to the second embodiment of the present invention. The difference from the first embodiment is that a transmissive liquid crystal display device LC (shaded portion) is disposed in the portion of the window portion 7 formed in the front panel DP. The transmissive liquid crystal display device LC is provided for the purpose of producing effects around the reels 6a to 6c during the game. Other configurations are the same as those of the first embodiment, and thus the description thereof is omitted here.

  FIG. 21 is a longitudinal sectional view (L-L ′ sectional view) of the portion of the transmissive liquid crystal display device LC described above and its periphery. The transmissive liquid crystal display device LC is provided at the back position of the window portion 7 formed on the front panel DP, and includes a liquid crystal display panel 300 and a backlight unit 301. The backlight unit 301 includes a light guide plate 302 disposed on the back surface of the liquid crystal display panel and a lighting device such as a cold cathode tube 303 (303a, 303b). Light from the cold cathode fluorescent lamps 303 provided on the upper and lower sides is guided into the light guide plate 302, and the entire surface of the liquid crystal display panel 300 is illuminated by this light. These transmissive liquid crystal display devices LC are attached to the back surface of the front panel DP by a mounting frame 304. Light sources 305 (305a, 305b) for reel illumination are provided on the upper and lower sides of the transmissive liquid crystal display device LC. The reels 6a to 6c are illuminated by the light source 305 for reel illumination. The liquid crystal display panel 300 controls the orientation of the liquid crystal disposed between the two glasses by voltage, and enables various displays by transmitting light from the backlight unit 301 behind. The light guide plate 302 that constitutes the backlight 301 is made of synthetic resin or the like, and is formed to have approximately the same size as the liquid crystal display panel 300. Further, when the liquid crystal display panel 300 is in a transmissive state due to the orientation of the liquid crystal of the liquid crystal display panel 300, the rear reels 6a to 6c are configured to have sufficient light transmittance so that the rear reels 6a to 6c can be visually recognized through the light guide plate 302. Has been. The cold cathode tube 303 is formed in a cylindrical shape and is provided in contact with the upper and lower sides of the light guide plate 302.

  Then, as shown in FIG. 22, the transmissive liquid crystal display device LC has a plurality of control patterns in which the area of the effect screen is in a predetermined state. FIG. 22A is a diagram of effect display performed in a state where the reels 6a to 6c are stopped. The shaded portion is the portion where the effect image is displayed. In this state, effect display is performed on the entire surface of the transmissive liquid crystal display device LC. FIG. 22B is a diagram of effect display performed in a state where the reels 6a to 6c are rotating. In this state, a non-image display area in which the effect image is not displayed is formed in an area located in front of the reel (area without hatching). As a result, the rear reels 6a to 6c can be seen through. FIG. 22C is an effect display diagram when the setting change operation is performed. In this state, when the display device 9 is viewed from the back surface, a non-image display area in which an effect image is not displayed in the area on the line of sight.

  FIG. 23 is a diagram showing an electrical block configuration of the slot machine A ′. The difference from the first embodiment is that a liquid crystal display panel 300 and a backlight unit 301 for illuminating the liquid crystal display panel 300 are connected to the first sub-control unit 102 via a driver circuit. The ROM 106 of the main control unit is provided with a transmission mode command program for commanding the transmission mode of the transmissive liquid crystal display device LC. Furthermore, the ROM 128 of the first sub-control unit 102 stores transmission mode data 308 that designates a transmission region for the purpose of forming transmission image data to be displayed on the transmission liquid crystal display device LC. The first sub-control unit 102 also stores effect image data for effect display on the liquid crystal display panel 300. Further, the RAM 129 is also provided with a transmission flag storage unit 309 that stores a flag state for controlling the transmission mode. Since the other configuration is the same as that of the first embodiment, the same reference numerals are given and description thereof is omitted. The main control unit 101 determines the control state of the gaming machine and instructs the first sub control unit 102 about the transmission state of the transmissive liquid crystal display device LC. The first sub-control unit 102 controls the liquid crystal display panel 300 and the backlight unit 301 based on this command.

  FIG. 24 is a flowchart showing transmission region control in the main control unit 101 of the slot machine A ′. First, in step S500, 0 is written as the value of the transparency flag F3, and flag transmission processing for transmitting the value of F3 to the first sub-control unit 102 is performed in step S501. The transmission flag F3 is a flag for controlling the shape of the transmission region of the liquid crystal display panel 300. 0 is an initial value, and indicates a state in which the entire liquid crystal display panel 300 is used as an effect screen without forming a transmission region. In step S502, it is determined whether the reels 6a to 6c are rotating. This determination is made when any one of the reels 6a to 6c is rotating. If the reel is rotating, 1 is written as the value of the transmission flag F3 in step S503, and a flag transmission process for transmitting the value of F3 to the first sub-control unit 102 is performed in step S504. If the reel is not rotating, it is determined in step S505 whether the setting change mode is in effect. If it is in the setting change mode, 2 is written as the value of the transparency flag F3 in step S506, and flag transmission processing is performed to transmit the value of F3 to the first sub-control unit 102 in step S507. On the other hand, if it is not in the setting change mode in step S505, the processing is terminated as it is. These processes are performed by a transmission mode command program stored in the ROM 307 of the main control unit 101.

  FIG. 25 is a flowchart showing the transmission area control in the first sub-control unit 102 of the slot machine A ′. First, in step S600, the value of the transparency flag F3 transmitted from the main control unit 101 is received and stored in the transparency flag temporary storage unit 309 of the RAM 129. In step S602, the value of the transmission flag F3 is determined. If F3 = 0 in step S602, the process is terminated without forming a transmission region. On the other hand, if F3 = 1 in step S603, the transmissive area pattern 1 is formed in step S604. This transmissive area pattern 1 is the transmissive area pattern shown in FIG. 22B, and when this transmissive area pattern is formed, the reels 6a to 6c can be visually recognized from the front surface. In forming the transmissive area pattern, the first sub-control unit 102 synthesizes the effect image pattern in which the transmissive area is formed using the transmission mode data 308 of the ROM 128 and the effect image data similarly stored in the ROM 128. Is done. If F3 = 2 in step S605, the transmissive area pattern 2 is formed in step S605. This transmissive area pattern 2 is the transmissive area pattern shown in FIG. 22C, and when this transmissive area pattern is formed, the display is started from the back surface of the front door 2 in the working state of FIG. 5B. The portion 9 becomes visible. The transmissive region pattern is also formed by the same process as that of the transmissive region pattern 1.

  By performing the processing shown in FIGS. 24 and 25, when the reel is rotating, the transmissive liquid crystal display device LC is controlled so as to form the transmissive region of FIG. Inside, the transmissive liquid crystal display device LC is controlled so that the transmissive region of FIG. 22C is formed. As a result, in the slot machine A ', it is possible to produce an effect with a high effect in the peripheral area of the reels 6a to 6c, and the visibility to these is not disturbed while the reels 6a to 6c are rotating. Further, during the setting change operation, the display 9 is controlled so that the portion of the display 9 can be seen from the back side, so that the convenience during work is improved even in the configuration in which the display 9 is used as the set value display unit.

  Other controls during the game or abnormal process control are the same as those in the first embodiment described above, and thus the description thereof is omitted here.

  In the second embodiment, the example in which the setting change mode is determined in step S505 in FIG. 24 and the transmissive region pattern 2 is formed has been shown. However, instead of the process in step S505, the second release is performed. Processing for determining whether or not the angle sensor 53 is on may be used. In this case, it is detected that the opening angle of the front door 2 has reached Y degrees, and the transmissive region pattern 2 is formed. By this control, the frequency of performing control for forming the transmissive region pattern 2 can be reduced, and the control burden is reduced.

  In addition, the formation of the transparent area pattern 2 in the second embodiment is not limited to the setting change mode, and may be performed with a predetermined probability when the reel being played is not rotating. At this time, a display device having the same size as that of the transmissive region pattern 2 appears behind the transmissive liquid crystal display device LC on which the transmissive region pattern 2 is formed. It is good also as composition which performs. The display of the information related to the lottery includes a display for informing a state in which the bonus flag is established, or the number of remaining games in a specific game state such as a bonus game or an RT game.

  When it is set as said structure, formation control of the transmissive area | region pattern 2 can be used for the expectation improvement with respect to the alerting | reporting of the various information in a game, and the interest of a game can be raised.

Moreover, in said 2nd Embodiment, it is set as the structure which has arrange | positioned the effect display apparatus 3 in the upper part of the front door 2 similarly to 1st Embodiment, However, The effect performed with this effect display apparatus 3 is a transmissive liquid crystal display. It is good also as a structure which makes it the structure performed with the apparatus LC, and excluded the production | presentation display apparatus 3. FIG.

  Next, a third embodiment according to the present invention will be described.

  FIG. 26 shows a slot machine A ″ according to the third embodiment of the present invention. The appearance of the slot machine with the front door 2 closed is almost the same as in the first and second embodiments, but the front door 2 covers the upper side of the reel block 33 as shown in FIG. It is separated into an upper front door 2a and a lower front door 2b that covers the lower side, and each is separately attached to be rotatable. And although the figure of the state which removed the upper front door 2a is shown in the figure, the upper front door 2a is hingedly attached as shown by the arrow S, and is attached.

  A hook engaging structure including a hook 400 and a hook hole 401 is formed in part at a portion where the upper front door 2a and the lower front door 2b are in contact with each other. When the locking device 14 is rotated to the right, the lower front door 2b can be opened in advance, and when the locking device 14 is rotated to the left, the upper front door 2a can be opened in advance. become able to. With these structures, the way of opening the upper front door 2a and the lower front door 2b can be appropriately selected as necessary.

  The reel block placement surface BP is provided in a plate shape on the left and right sides of the inside of the housing, and the end surface of the reel block placement surface on the front door 2 side, the joint surface FP of the upper front door 2a, and the lower side The joint surface SP of the front door 2b is formed so as to substantially coincide with the end surface on the housing side. For this reason, when the lower front door 2b is opened while the upper front door 2a is closed, the upper portion of the casing side reel block is kept closed. On the other hand, when the upper front door 2a is opened while the lower front door 2b is closed, the lower side of the casing side reel block is kept closed.

  An opening angle detection mechanism 22a is provided at the hinge portion of the upper front door 2a. Although not shown, the opening angle detection mechanism 22b is provided in the hinge portion of the lower front door 2b as well as the hinge portion of the upper front door 2a. Since the configuration of the other parts is the same as that of the first embodiment, description thereof is omitted.

  The opening angle detection mechanism 22b provided in the lower front door 2b has the same configuration as the opening angle detection mechanism 22 in the first embodiment, and corresponds to the first opening angle sensor 52 in the first embodiment. The opening angle is detected by a lower second opening angle sensor 503 corresponding to the first side opening angle sensor 502 and the second opening angle sensor 53. The opening angle detection mechanism 22a provided in the upper front door 2a has substantially the same configuration as the opening angle detection mechanism 22 in the first embodiment, but corresponds to the second opening angle sensor 53 in the first embodiment. Only the upper first opening angle sensor 602 corresponding to the first opening angle sensor 52 is provided.

  The detection signals from the lower first opening angle sensor 502, the lower second opening angle sensor 503, and the upper first opening angle sensor 602 are all input to the main control unit 101. Since the electrical block configuration other than this configuration is the same as that of the first embodiment, the description thereof is omitted here.

  FIG. 27 shows flag processing related to the display mode on the display unit 9, which is performed using the display mode determination program in the ROM 113 and the display mode temporary storage unit in the RAM 116 in the main control unit 101 of the slot machine in the present embodiment. It is a flowchart.

  First, in step S700, it is confirmed whether the upper front door 2a or the lower front door 2b is opened. Each of the upper front door 2a and the lower front door 2b is provided with a sensor for detecting opening, and this determination is performed based on these signals. If either one is open, 0 is set as the value of the display permission flag F0 in step S701. Subsequently, in step S702, it is confirmed whether or not the upper first opening angle sensor 602 is turned on. If this determination is NO, timing is started, and the process proceeds to step S703 to determine whether or not a predetermined time has elapsed in the state of F0 = 0. If a predetermined time has elapsed in the state of F0 = 0, abnormality notification processing is performed in step S704. This is because there is a high possibility that a fraudulent act that is performed by slightly opening the door is performed. If YES, the process goes to step S705 to check whether the lower first opening angle sensor 502 is once turned on. In the case of NO, timing is started in the same manner as described above, and the determination process in step S703 is performed. This is because when the set value is changed, it is necessary to once operate the power supply, and therefore it is necessary to open the lower front door 2b accommodating the power supply to an angle at which one end can be operated. If it is determined that there has been no operation to open this one end, it is highly possible that an illegal act has been performed, so an abnormality notification is given. The determination processing in step S705 includes determining that the lower first opening angle sensor 502 has been on for a predetermined time (for example, 1 second or longer). This determination can prevent post-detection due to an instantaneous rise such as noise.

  If the determination in step S705 is YES, the display permission flag F0 = 1 is set in step S706, and at the same time, 0 is set as the value of the display reverse flag F1 in step S707. In step S708, it is confirmed whether or not the lower second opening angle sensor is turned on. This process is a process for detecting that the opening angle of the lower front door 2b on which the indicator 9 is disposed is equal to or greater than Y degrees. If it is turned on, the display reverse flag F1 = 1 is set in step S709.

  The display mode setting process and the setting value display process performed in response to the flag process are performed according to the same flowcharts as those in FIGS. 14 and 11 of the first embodiment. Further, the display process of the abnormality information is the same as that of the first embodiment except for the flag process, and the description thereof is omitted here.

  A characteristic point in the third embodiment is that the lower front door 2b is once opened to an open angle at which an internal operation is possible, and is set in a display permission state. With this control, once the power supply is operated, with the lower front door 2b closed or slightly opened, the upper front door 2a is opened to perform setting change work and abnormal state release work. Can do. For this reason, it becomes possible to perform work while visually recognizing the display 9 in a normal manner. In addition, even when the work is performed with the lower front door 2b greatly opened, the display mode on the display 9 is derived as the upside down mode as in the first embodiment. It can be easily confirmed and the work efficiency is improved.

  In each of the above embodiments, the opening angle detection mechanism 22 is shown as detecting the movement by converting the rotation in the horizontal direction into the vertical movement by the link mechanism, but the present invention is not limited to this, and the opening is detected. Any device that can detect that the angle has reached a predetermined position is applicable. For example, as shown in FIG. 28A, a rotation angle is detected by detecting a slit provided on the disk surface, or a semiconductor magnetoresistive element as shown in FIG. 28B is used. There may be.

  FIG. 28A shows an example in which the rotation angle is detected by a slit provided on the disk surface. A disc 701 provided inside a part (hinge portion) 1 ′ of the housing is connected to the shaft 20a via a rotary shaft 700 so that the shaft 20a and the disc 701 rotate as the front door 2 is opened. It has become. The left side of FIG. 28A is a view of the hinge portion as viewed from the front, and FIG. 28B is a cross-sectional view (MM ′ cross-sectional view) of the disk 701. . A sensor placement portion 702 is provided inside the part 1 ′ of the housing, and a first opening angle sensor 52 including a light projecting portion 52a and a light receiving portion 52b, a light projecting portion 53a, A second opening angle sensor 53 comprising a light receiving portion 53b is installed.

  As shown in the drawing on the right side, the disk 701 has a slit for allowing light from the light projecting portion 52a of the first opening angle sensor to pass from the point where the opening angle becomes X to the maximum opening angle. 703 and a slit 704 for allowing light from the light projecting portion 53b of the second opening angle sensor to pass from the point where the opening angle becomes Y to the maximum opening angle. With this structure, the first opening angle sensor 52 is turned on after the opening angle reaches X, and the second opening angle sensor 53 is turned on after the opening angle reaches Y. . In these configurations, the same effect can be obtained by performing the same control as in each embodiment.

  FIG. 28B shows an example in which the rotation angle is detected by a semiconductor magnetoresistive element. The shaft 20a is provided inside a part (hinge portion) 1 ′ of the housing and is connected to a gear 705 made of a magnetic material via a rotating shaft 706. When the front door 2 is opened, the shaft 20a and the gear 20 are connected. 705 rotates. Note that the left side of FIG. 28B is a view of the hinge portion as viewed from the front, and FIG. 28B is a view of the interior of the hinge portion as viewed from below (NN ′ cross-sectional view). ). A sensor unit including a magnet 707 and a semiconductor magnetoresistive element 708 is provided from a part 1 ′ of the housing, and the opening angle is detected by detecting a magnetic field that changes due to a change in distance from the gear 705. It has become. By counting the number of changes in the magnetic field, it is possible to know how much the opening angle is. Therefore, by performing this calculation, the same control as in each embodiment can be realized.

  Note that the type of sensor used to detect the open angle is not limited to the above, and other types of sensors can be used as long as they can detect the open angle, such as a reflective sensor or a conduction switch.

  In each of the above embodiments, the credit number display portion of the display unit 9 is shared as a set value display portion or an abnormality information display portion. However, the present invention is not limited to this, and is provided on the front surface of the gaming machine. Any display device may be used as long as it is arranged and displays predetermined information during a game. For example, the payout number display portion of the display device 9 may be shared as a set value display portion or an abnormality information display portion.

  Moreover, in each said embodiment, although the example which makes the indicator 9 directly visible from the back surface of the front door 2 through the window part 7 was shown, this invention is not restricted to this, The indicator 9 is let to pass through the window part 7. It is good also as visual recognition from the back of front door 2 indirectly. For example, the display 9 is arranged on the front panel surface DP instead of on the upper operation panel surface PN1, and the display device 9 is made visible by arranging a reflective surface on the upper operation panel surface. In this case, it is preferable that the display device 9 is disposed on the front panel surface DP below the window portion 7 and the reflection surface is disposed on the upper operation panel surface PN1 facing the display surface of the display device 9. The size of the reflecting surface is preferably formed to be approximately the same as or slightly larger than the display 9. At this time, the display surface of the display unit 9 is attached so as to form an angle of about 120 degrees with the upper operation panel surface, and the reflection surface provided on the upper operation panel surface PN1 is provided with a slight inclination toward the housing side. The transparent part of the window part 7 can be irradiated with light from the vessel 9. At this time, it is preferable to use a surface having a reflectance of 50% or more in the visible light (400 to 700 nm) region as the reflecting surface. However, it is not necessary to have a complete mirror surface, and it is sufficient if the display light can be reflected to such an extent that the display content of the display 9 can be visually recognized even on a rough surface. According to this structure, even if it is a case where the indicator 9 is attached to the front panel DP, it does not cause trouble during work. In this case, when the opening angle Y is reached, it is preferable to display the left-right reverse mode instead of the vertical reverse mode display in each embodiment described above.
