  Embodiments according to the gaming machine of the present invention will be described below with reference to the drawings. First, a functional flow of a gaming machine (hereinafter referred to as a pachislot machine) in the present embodiment will be described with reference to FIG.

  When a player inserts a medal and operates the start lever, one value (hereinafter, random number value) is extracted from random numbers in a predetermined numerical range (for example, 0 to 65535).

  The internal lottery means performs lottery based on the extracted random number value and determines an internal winning combination. By determining the internal winning combination, a combination of symbols that permits display along a winning determination line described later is determined. The types of symbol combinations include those related to “winning” in which merits such as paying out medals, re-games, bonuses, etc. are given to players, and other so-called “loses”. Is provided.

  Subsequently, after a plurality of reels have been rotated, when a stop button is pressed by the player, the reel stop control means determines the corresponding reel based on the internal winning combination and the timing when the stop button is pressed. Control to stop the rotation of.

  Here, in the pachislot, basically, the control of stopping the rotation of the corresponding reel is performed within a specified time (190 msec) from when the stop button is pressed. In the present embodiment, the number of symbols that move with the rotation of the reel within the specified time is referred to as “the number of sliding symbols”, and the maximum number is determined as four symbols.

  The reel stop control means displays the symbol combination as much as possible along the winning determination line using the specified time when an internal winning combination permitting display of the symbol combination related to winning is determined. Stop the reel rotation so that On the other hand, for the combination of symbols that are not permitted to be displayed by the internal winning combination, the reel rotation is stopped so that the combination is not displayed along the winning determination line using the specified time.

  Thus, when the rotation of the plurality of reels is all stopped, the winning determination means determines whether or not the combination of symbols displayed along the winning determination line is related to winning. When it is determined that the prize is related to a prize, a bonus such as a medal payout is given to the player. A series of flows as described above is performed as one game in the pachislot.

  Also, in the pachislot, in the above-described series of flows, various effects can be achieved by using video display performed by a liquid crystal display device, light output performed by various lamps, sound output performed by a speaker, or a combination thereof. Done.

  When the player operates the start lever, an effect random number value (hereinafter referred to as effect random number value) is extracted separately from the random value used for determining the internal winning combination. When the effect random number value is extracted, the effect content determining means determines, by lottery, what is to be executed this time from among a plurality of types of effect contents associated with the internal winning combination.

  When the content of the production is determined, the production execution means is linked to each opportunity such as when the rotation of the reel is started, when the rotation of each reel is stopped, or when the presence / absence of a prize is determined. To proceed with the production. In this way, in the pachislot, the player is given the opportunity to know or predict the determined internal winning combination (in other words, the combination of symbols to be aimed at) by executing the production contents associated with the internal winning combination. As a result, the player's interest is improved.

  In the pachislot in this embodiment, in addition to the above configuration, an authentication means (identification) that performs authentication using a non-contact information tag between the case housing the main control board and the attachment part of the case in the pachislot An information reading unit 400 (identification information reading devices 501 and 701 (described later)) is provided.

  This identification information reading means 400 has a non-contact information tag attached to the case and a pachislot side information reading device, and the information reading device is stored in the non-contact information tag from the non-contact information tag on the case side. By reading the identification information, it is authenticated whether the proper case (main control board) is correctly attached.

  Each of the non-contact information tag and the information reader has a coiled antenna element, and the information reader is caused by electromagnetic induction of a magnetic field generated between the coil of the non-contact information tag and the coil of the information reader. The identification information stored in the memory of the contactless information tag can be read without contact. The coil of the non-contact information tag is attached to the tip of the protruding portion of the case to which the non-contact information tag is attached, and thereby the coil is disposed at a position separated from the board surface of the main control board housed in the case. Thus, the deterioration of the electromagnetic conversion characteristics between the coil of the non-contact information tag and the coil of the information reader can be suppressed.

  When the identification information read from the non-contact information tag is regular identification information, the information reader can determine that a regular non-contact information tag (that is, a regular case) is attached. . The regular case means a case in which a regular main control board is stored.

  As described above, when the identification information read from the non-contact information tag in the information reading device is regular identification information, the game is executed in the pachislot, whereas the read identification information is not regular identification information. In such a case, processing such as prohibiting the execution of the game or performing a predetermined warning notification is executed.

  In addition, when the information reader cannot correctly read the identification information from the non-contact information tag, the case where the non-contact information tag is not attached at the proper position (case where there is a possibility of fraud) In this case, as in the above-mentioned case where the legitimate identification information could not be read, the execution of the game can be restricted, because it can be determined that the case is attached or the case itself is not attached. Or, a predetermined warning notification is performed.

  This makes it possible to determine when the case (main control board) is not correctly attached or when a case that is not a regular case is attached (when an illegal act is performed).

Note that a medal sensor, which will be described later, is provided on the path through which the medal passes in the selector 31, and detects that an appropriate medal has passed.

(Main board mounting configuration)
The main board 301 is housed in a resin case 310 which is a board housing case, and the case 310 containing the main board 301 is fixed to a predetermined mounting portion of the cabinet 20 by fixing means such as screws. Has been. In the present embodiment, a configuration in which the main board 301 is fixed to the cabinet 20 side will be described. However, the configuration is not limited to this, and the main board 301 may be fixed to the front door 30 side.

  FIG. 4 is a side view showing the case 310 in a state where the main board 301 is accommodated, and FIG. 5 is a plan view showing the case 310. As shown in FIGS. 4 and 5, the case 310 is constituted by an upper case 311 and a lower case 312 that constitute the casing portion, and the main substrate 301 is accommodated inside the upper case 311 and the lower case 312. It is made to do. The main board 301 is fixed in the case between the upper case 311 and the lower case 312 by fixing means such as screws. The case 310 is provided with a screw hole 314 that penetrates from the upper case 311 to the lower case 312, and the case 310 can be screwed to a predetermined position of the cabinet 20 of the pachislot machine 10 through the screw hole 314. It is made like that. Incidentally, a screw 525 (described later) used for screwing is preferably made of resin. By using a resin screw instead of a metal screw, in the exchange of information by electromagnetic induction between the non-contact IC tag 401 and the information reading device 501 described later, there is a metal part in the vicinity. Degradation of electromagnetic conversion characteristics can be suppressed.

  In addition, metal parts are not arranged in a predetermined area AR1 in which a non-contact IC tag 401 (described later) of the case 310 is provided, and this also suppresses deterioration of electromagnetic conversion characteristics. Has been made.

  The upper case 311 of the case 310 is provided with a protruding portion 315 that protrudes in a direction away from the main substrate 301 at a substantially central portion of the surface portion facing the substrate surface of the stored main substrate 301. A plate-like non-contact information tag (hereinafter, referred to as a non-contact IC tag) 401 is fixed.

  That is, as shown in FIG. 6, a recess 317 is formed on the protruding tip surface portion of the protruding portion 315 of the upper case 311 so as to match the outer shape of the non-contact IC tag 401. As shown in FIG. A non-contact IC tag 401 is fixed to the recess 317 by adhesion or the like. In the case of the present embodiment, the shape and formation position of the recess 317 (relative positional relationship with the screw hole 314) are formed in a predetermined shape and position according to the pachislot 10 to which the case 310 is attached. As a result, as shown in FIG. 8, when the case 310 to which the non-contact IC tag 401 is attached is fixed to the protrusion 521 formed on the cabinet 20 side of the pachislot 10 using the screw 525, the non-contact IC At a position where an antenna coil 403 (described later) of the tag 401 and an antenna coil 503 of the information reading device 501 fixed on the cabinet 20 side are separated from the substrate surface of the main substrate 301 in a direction orthogonal to the substrate surface. It is made to confront.

  Note that at least a portion of the case 310 where the non-contact IC tag 401 is provided (a portion including the protruding portion 415) and a portion where the antenna coil 503 of the information reading device 501 of the cabinet 20 is provided are each formed of a resin member. In addition, deterioration of electromagnetic conversion characteristics between the antenna coils is suppressed. Preferably, if the upper case 311 and the lower case 312 are all made of a resin material, it is possible to further suppress the deterioration of electromagnetic conversion characteristics.

  Next, the non-contact IC tag 401 and the information reading device 501 will be described. In the case of the present embodiment, as the non-contact IC tag 401, a proximity type tag called an RFID (Radio Frequency Identification) tag that is used to exchange information using electromagnetic induction between coils is used. FIG. 9 is a schematic diagram showing a proximity non-contact IC tag 401 and an information reading device 501 for reading information from the non-contact IC tag 401. In FIG. 9, the case 310 to which the non-contact IC tag 401 is attached is omitted.

  As shown in FIG. 9, the non-contact IC tag 401 has a configuration in which an IC chip 402 and an antenna coil 403 are arranged on a resin sheet material. The IC chip 402 and the antenna coil 403 are laminated with a sheet material (not shown).

  The information reading device 501 has a configuration in which an information reading unit 502 is connected to an antenna coil 503. The antenna coil 503 is provided in the cabinet 20 of the pachi-slot 10 (FIG. 3).

  FIG. 10 is a block diagram showing a proximity non-contact IC tag 401 and an information reading device 501 for reading information from the non-contact IC tag 401. As shown in FIG. 10, the non-contact IC tag 401 includes an IC chip 402 that stores identification information, and an antenna coil 403 connected to the IC chip 402. Identification information is stored in advance in the IC chip 402 and is read by the information reading device 501 in a non-contact manner.

  That is, the information reading apparatus 501 includes a coil antenna 503, a transmission modulation unit 514, a reception demodulation unit 515, a clock oscillator 516, and a control unit 511. The control unit 511 generates a 13.56 MHz signal generated in the clock oscillator. By amplifying the signal by the transmission modulation unit 514 and applying it to the antenna coil 503, an alternating magnetic field of 13.56 MHz is generated from the antenna coil 503.

  In the non-contact IC tag 401, when the antenna coil 401 is held over the antenna coil 503 on the information reading device 501 side, a part of the magnetic field passes through the antenna coil 403, thereby generating an alternating voltage. This AC voltage is supplied to the IC chip 402 of the non-contact IC tag 401.

  The IC chip 402 includes a control unit 411, a power supply unit 412, a clock recovery unit 413, a transmission modulation unit 414, and a reception demodulation unit 415. The power supply unit 412 converts the alternating voltage generated in the antenna coil 403 into direct current. Thus, the voltage is reduced to a low voltage and supplied to the control unit 411. Incidentally, the electric power that can be obtained by the control unit 411 decreases as the non-contact IC tag 401 moves away from the information reading device 501.

  In this way, the control unit 411 operates with the electric power obtained from the antenna coil 403 through the power supply unit 412.

  Further, in the non-contact IC tag 401, since the clock oscillator is not provided, the clock regeneration unit 413 shapes the waveform based on the 13.56 MHz AC voltage generated in the antenna coil 403, so that the control unit 411 Get a usable clock. Thus, the non-contact IC tag 401 generates various timings based on the frequency of the magnetic field generated by the information reading device 501 (the clock of the information reading device 501), and operates in synchronization with this clock.

  When the non-contact IC tag 401 is held over the antenna coil 503 of the information reader 501, the reflection on the carrier wave (calling signal) emitted by the information reader 501 is changed according to the identification information stored in the non-contact IC tag 401. . The control unit 511 of the information reading device 501 reads the identification information stored in the non-contact ID tag 401 based on this reflection change.

  As described above, in the pachislot machine 10 of the present embodiment, as a configuration for attaching the case 310 containing the main board 301 to the cabinet 20, for example, using fastening means such as screws, the case 310 is attached to the cabinet 20. It is made to fix to a predetermined position.

  In the case 310, a protruding portion 315 is formed at a predetermined position, and a screw serving as a fastening means between the case 310 and the cabinet 20 is passed through the protruding tip surface portion of the protruding portion 315. A recess 317 is formed in which the positional relationship with the screw hole 314 is precisely defined.

  Thereby, in a state where the case 310 is fixed to the cabinet 20, the antenna coil 403 of the non-contact information tag 401 fixed to the case 310 and the antenna coil 503 of the information reading device 501 fixed to the cabinet 20 side are accurate. It will be confronted to face directly. The induced electromotive force generated in the antenna coil 403 is proportional to the change per unit time of the magnetic flux passing through the antenna coil 403, so that the antenna coils 403 and 503 are correctly opposed to each other between the antenna coils 403 and 503. Since the magnetic flux passing between the two coils is the largest, an induced electromotive force due to electromagnetic induction generated between the two coils can be sufficiently obtained. In this case, the non-contact IC tag 401 can return identification information in response to an inquiry from the information reading device 501.

  In contrast, when the case 310 is fixed to the cabinet 20 and the antenna coils 403 and 503 are deviated, the magnetic flux passing through the antenna coils 403 and 503 is reduced, so that induction induced between the two coils is generated. Electric power cannot be obtained sufficiently. As a result, in the information reading device 501, the identification information of the non-contact IC tag 401 cannot be read although the case 310 is attached. That is, in a case where the projecting portion 315 is not provided, or in a case where the projecting portion 315 is provided, the formation position (that is, the formation position of the recess 317) is different from the normal position. The attachment position of the non-contact IC tag 401 fixed to the case is not a normal position. In this case, in a state where the case is fixed to the cabinet 20, the antenna coil 403 of the non-contact IC tag 401, The relative position of the information reading device 501 with respect to the antenna coil 503 is not exactly the directly facing position, and as a result, it is difficult for the information reading device 501 to read the identification information of the non-contact IC tag 401. .

  Even when the case 310 to which the non-contact IC tag 401 is attached at an accurate attachment position is fixed to the cabinet 20, the non-contact IC tag 401 fixed to the case 310 is a regular tag. If not, the information reading device 501 can detect that the read identification information is not correct identification information even if the identification information can be read. That is, when a non-authorized case containing an improperly created main board is attached, the non-contact IC tag 401 provided in the case is not a regular tag and is stored in the tag. The identification information is also different from the regular identification information. Thus, even when the information reading device 501 can read the identification information, if the read identification information is not regular identification information, the information non-contact IC tag 401 (that is, the regular identification information) It can be detected that the case 310) is not attached. Here, the regular case means a case in which the regular main board 301 is stored.

  The main board 301 is fixed by fixing means such as a screw in the case 310. For example, as a technique for preventing the main board 301 from being illegally replaced with another main board, for example, the main board 301 is used. A method in which the upper case 311 and the lower case 312 are completely fixed by welding or the like in a state in which the substrate 301 is stored, or a seal or the like is affixed to a fitting position of the upper case 311 and the lower case 312 in a fixed state A method or the like can be used.

  According to the method in which the upper case 311 and the lower case 312 are completely fixed by welding or the like, in order to replace the main board 301 illegally, the case is broken. It becomes difficult to fix. Further, according to the method of sticking the seal at the fitting position of the upper case 311 and the lower case 312, when the upper case 311 and the lower case 312 are removed for the purpose of replacing the main board 301, the seal is broken. This leaves a trace of fraud. Thereby, for example, the staff in the hall can monitor this to prevent fraud.

  As described above, the information reader 501 can read the identification information of the regular non-contact IC tag 401 only when the regular case 310 containing the regular main board 301 is attached to the cabinet 20. It has become.

  The information reading device 501 stores regular identification information in an internal memory (not shown) of the control unit 511 in advance, and always reads from the non-contact IC tag 401 while the power supply of the pachislot 10 is inserted. When the process of reading the identification information is executed and the proper identification information is correctly read, the main control circuit 50 controls the progress of the game to the permitted state by notifying the main control circuit 50 to that effect. The On the other hand, when it becomes difficult to read the identification information or when it is determined that the read identification information is not legitimate identification information, the information reading device 501 notifies the main control circuit 50 accordingly. Thus, for example, the progress of the game is restricted or a predetermined warning is notified by the main control circuit 50.

  Thereby, for example, when the case 310 is exchanged from a regular case to a non-regular case due to a fraud, it is possible to immediately detect the fraud.

  Further, the case 310 is formed with a protrusion 315, and the non-contact IC tag 401 is fixed to the tip of the protrusion 315. Thus, by attaching the non-contact IC tag 401 to the tip of the protrusion 315, the non-contact IC tag 401 is fixed at a position separated from the main board 301 housed in the case 310. Become.

  In the case 310 in which the non-contact IC tag 401 is fixed at a position separated from the main substrate 301 by disposing various circuit elements and the like on the main substrate 301, the information reading with the non-contact IC tag 401 is performed. When information is exchanged with the apparatus 501 by electromagnetic induction, it is possible to effectively avoid the deterioration of electromagnetic conversion characteristics caused by metal parts such as circuit elements of the main board 301. In particular, the non-contact IC tag 401 is attached at a position separated from the substrate surface of the main substrate 301 accommodated in the case 310 in a direction orthogonal to the substrate surface, so that the outer shape of the case 310 is the main substrate. Although the thickness increases in the thickness direction of 301, it is possible to avoid an increase in size in a plane parallel to the substrate surface of main substrate 301. In particular, in the component parts such as the main board 301, since the thickness thereof is small, restrictions on the installation space in the thickness direction are reduced. Therefore, as in the configuration of the present embodiment, by attaching the non-contact IC tag 401 to a position separated in the thickness direction of the main substrate 301, the non-contact IC tag 401 can be attached without being greatly limited by space. It becomes possible.

(Front door open / close detection device)
As described above with reference to FIG. 3, the front door 30 is supported so as to be openable and closable with respect to the cabinet 20. In the pachislot machine 10, the front door 30 detects whether or not the front door 30 is open. Opening detection device 600 is provided. As shown in FIG. 11, the door opening detection device 600 includes an information reading device 701 provided in a part of the cabinet 20, and a cabinet in a state where the front door 30 is a part of the front door 30 and is closed. And a non-contact information (IC) tag 601 having an antenna coil 603 provided at a position facing the antenna coil 703 of the information reading device 701 on the 20th side. Note that a part of the front door 30 where the non-contact IC tag 601 is provided (a part including a protruding part 655 described later) and a part where the antenna coil 703 of the information reading device 701 of the cabinet 20 is provided (a part including the protruding part 755). Are each formed of a resin member so as to suppress deterioration of electromagnetic conversion characteristics between antenna coils.

  The configurations of the non-contact IC tag 601 and the information reading device 701 are the same as those of the non-contact IC tag 401 and the information reading device 501 described above with reference to FIG. As a result, as shown in FIG. 11, in the closed state where the front door 30 is closed, the information reading unit 702 of the information reading device 701 can read the identification information of the non-contact IC tag 601. On the other hand, as shown in FIG. 12, in the opened state where the front door 30 is opened, it is difficult for the information reading unit 702 of the information reading device 701 to read the identification information of the non-contact IC tag 601. It is in a state.

  As a result, when it becomes difficult for the information reading device 701 to read the identification information of the non-contact IC tag 601, the main control circuit 50 notifies the main control circuit 50 (described later) to that effect. It can be detected that the front door 30 is opened. In this case, the main control circuit 50 can prevent fraud by executing a process such as limiting the progress of the game or performing a predetermined warning notification.

  Incidentally, the mounting structure of the antenna coil 603 of the non-contact IC tag 601 and the antenna coil 703 of the information reading device 701 shown in FIGS. 11 and 12 is the mounting structure of the non-contact IC tag 401 in the case 310 described above with reference to FIG. Similarly to the above, these antenna coils 603 and 703 are provided at the distal ends of the protruding portions 655 and 715 protruding from the periphery. Thereby, for example, when there are metal parts such as metal parts around the antenna coil 603 in the front door 30 and the electromagnetic conversion characteristics between the coils in the cabinet 20, the electromagnetic conversion characteristics are influenced around the antenna coil 703 in the cabinet 20. Even when there is a metal part or the like that provides the antenna coil 603, the position where the antenna coils 603 and 703 face each other can be kept away from the metal part or the like. Thereby, deterioration of the electromagnetic conversion characteristics by the antenna coils 603 and 703 can be suppressed, and the open state of the front door 30 can be reliably detected.

  Note that in the attachment example of the non-contact IC tag 601 and the information reading device 701 shown in FIGS. 11 and 12, the case where the protrusions 655 and 715 are formed on both the non-contact IC tag 601 side and the information reading device 701 side will be described. However, the present invention is not limited to this, and it may be provided in either one. In this case, when there are metal parts around the antenna coil 603 on the front door 30 side, a protrusion 655 is provided on the front door 30 side (that is, the attachment side of the non-contact IC tag 601). In the case where metal parts are present around the antenna coil 703 on the cabinet 20 side, the projecting portion 755 is provided on the cabinet 20 side (that is, the mounting side of the information reader 701). Degradation of conversion characteristics can be suppressed.

  FIG. 13 is a block diagram showing a proximity non-contact IC tag 601 and an information reading device 701 for reading information from the non-contact IC tag 601. As shown in FIG. 13, the non-contact IC tag 601 includes an IC chip 602 that stores identification information, and an antenna coil 603 connected to the IC chip 602. The IC chip 602 stores identification information in advance and can be read by the information reading device 701 in a non-contact manner.

  That is, the information reading apparatus 701 includes a coil antenna 703, a transmission modulation unit 714, a reception demodulation unit 715, a clock oscillator 716, and a control unit 711. The control unit 711 generates a 13.56 MHz signal generated in the clock oscillator. The antenna coil 703 generates an alternating magnetic field of 13.56 MHz by being amplified by the transmission modulation unit 714 and applied to the antenna coil 703.

  In the non-contact IC tag 601, when the antenna coil 601 is held over the antenna coil 703 on the information reading device 701 side, a part of the magnetic field passes through the antenna coil 603, thereby generating an alternating voltage. This AC voltage is supplied to the IC chip 602 of the non-contact IC tag 601.

  The IC chip 602 includes a control unit 611, a power supply unit 612, a clock regeneration unit 613, a transmission modulation unit 614, and a reception demodulation unit 615. These functions are the control of the contactless IC tag 401 described above with reference to FIG. The same as the unit 411, the power supply unit 412, the clock recovery unit 413, the transmission modulation unit 414, and the reception demodulation unit 415.

  When the non-contact IC tag 601 is placed over the antenna coil 703 of the information reader 701, the reflection of the carrier wave emitted by the information reader 701 is changed according to the identification information stored in the non-contact IC tag 601. The control unit 711 of the information reading device 701 reads the identification information stored in the non-contact ID tag 601 based on the change in reflection.

  As described above, when the front door 30 is closed, the antenna coil 603 of the non-contact information tag 601 of the front door 30 and the antenna coil 703 of the information reading device 701 fixed to the cabinet 20 side are accurately detected. They will face each other so that they face each other. The induced electromotive force generated in the antenna coil 603 is proportional to the change per unit time of the magnetic flux passing through the antenna coil 603, so that when the antenna coils 603 and 703 are correctly facing each other, between the antenna coils 603 and 703. Since the magnetic flux passing between the two coils is the largest, an induced electromotive force due to electromagnetic induction generated between the two coils can be sufficiently obtained. In this case, the non-contact IC tag 601 can return identification information in response to an inquiry from the information reading device 701. On the other hand, when the front door 30 is open, the antenna coils 603 and 703 do not face each other, so that no induced electromotive force can be obtained between the two coils. As a result, the information reading device 701 cannot read the identification information of the non-contact IC tag 601.

  The information reading device 701 stores regular identification information in an internal memory (not shown) of the control unit 711 in advance, and always detects from the non-contact IC tag 601 while the power supply of the pachislot 10 is inserted. When the process of reading the identification information is executed and the proper identification information is correctly read, the main control circuit 50 controls the progress of the game to the permitted state by notifying the main control circuit 50 to that effect. The On the other hand, when it becomes difficult to read the identification information, the information reading device 701 notifies the main control circuit 50 to that effect, so that the main control circuit 50 causes the progress of the game, for example. It is restricted or a predetermined warning is notified.

  Thereby, for example, when the front door 30 is opened by an illegal act, the illegal act can be detected immediately.

  Further, the front door 30 is formed with a protrusion 655, and a non-contact IC tag 601 is fixed to the tip of the protrusion 655. As described above, the non-contact IC tag 601 is attached to the tip of the protruding portion 655, so that the non-contact IC tag 601 is in a state of being separated from other metal parts provided on the front door 30. . Further, the cabinet 20 has a protrusion 755, and the antenna coil 703 of the information reading device 701 is fixed to the tip of the protrusion 755. As described above, the antenna coil 703 is attached to the tip of the projecting portion 755, so that the antenna coil 703 is in a state of being separated from other metal components provided in the cabinet 20. As a result, when the antenna coil 603 on the non-contact IC tag 601 side and the antenna coil 703 on the information reading device 701 side face each other and electromagnetic induction action occurs between them, suppression of deterioration of electromagnetic conversion characteristics due to a metal negative product or the like is suppressed. can do.

The start switch 110S, which is a start operation detecting means, detects that the start lever 110 has been operated by the player (start operation).

  The medal sensor 40S detects that the medal received in the medal insertion slot 40 has passed through the selector 31 described above. The bet switch 132S detects that the bet button 132 has been pressed by the player. Further, the settlement switch 134S detects that the settlement button 134 has been pressed by the player.

(Peripheral devices and circuits)
Peripheral devices whose operations are controlled by the microcomputer 60 include stepping motors 71L, 71C, 71R, a 7-segment display 114, and a hopper 150. Further, a circuit for controlling the operation of each peripheral device is connected to the output port of the microcomputer 60.

  The motor drive circuit 72 controls driving of stepping motors 71L, 71C, 71R provided corresponding to the reels 120L, 120C, 120R. The reel position detection circuit 70 detects a reel index indicating that the reel has made one rotation by means of an optical sensor having a light emitting part and a light receiving part in accordance with each reel 120L, 120C, 120R.

  The stepping motors 71L, 71C, 71R have a configuration in which the momentum is proportional to the number of output pulses and the rotation axis can be stopped at a specified angle. The driving force of the stepping motors 71L, 71C, 71R is transmitted to the reels 120L, 120C, 120R via gears having a predetermined reduction ratio. Each time one pulse is output to the stepping motors 71L, 71C, 71R, the reels 120L, 120C, 120R rotate at a constant angle.

  The main CPU 61 counts the number of times the pulses are output to the stepping motors 71L, 71C, 71R after detecting the reel index, thereby rotating the rotation angles of the reels 120L, 120C, 120R (mainly, how many symbols the reels have) The position of each symbol arranged on the surface of the reels 120L, 120C, 120R is managed.

  The display unit drive circuit 115 controls the operation of the 7-segment display 114. The hopper drive circuit 152 controls the operation of the hopper 150. The payout completion signal circuit 153 manages the detection of medals performed by the medal detection unit 151 provided in the hopper 150, and checks whether or not the medals discharged from the hopper 150 have reached the payout number.

  As described above with reference to FIG. 10, the information reading device 501 reads the identification information stored in advance in the non-contact IC tag 401 (FIG. 10), and when the read identification information is regular identification information, This is notified to the main CPU 61. On the other hand, when the read identification information is not regular identification information, or when it is difficult to read the identification information, the information reading device 501 notifies the main CPU 61 to that effect.

  The main CPU 61 is configured to execute a game by receiving a reading result from the information reading device 501. That is, when the reading result from the information reading device 501 is a result of reading regular identification information, the main CPU 61 continues the game without limiting the progress of the game. On the other hand, when the reading result from the information reading device 501 is not legitimate identification information, or when it is a result of failure to read information without contact, the main CPU 61 restricts the progress of the game. In addition, a command for warning notification is sent to the sub-control circuit 80. The restriction of the progress of the game means a process of interrupting the game that has been executed so far, and the warning notification means that, for example, a regular case (main board 301) is attached to the liquid crystal display device 210. Displaying information such as character information indicating that there is no information and symbols suggesting this, flashing various lamps 212 provided in the pachislot 10 in a specific pattern, or outputting a specific warning sound from the speaker 214 This means a notification process.

Further, the sub CPU 81 turns on and off the lamp 212 in accordance with the lamp data designated by the contents of the effect.

[Configuration of data table stored in main ROM]
This completes the description of the circuit configuration of the pachi-slot 10. Next, the configuration of various data tables stored in the main ROM 62 will be described with reference to FIGS.

[Design arrangement table]
The symbol arrangement table will be described with reference to FIG. The symbol arrangement table defines the position of each symbol in the rotation direction of each of the reels 120L, 120C, and 120R and data (hereinafter referred to as symbol code) specifying the type of symbol arranged at each position.

  In the symbol arrangement table, when the reel index is detected, the symbol position existing in the middle of the display window is set to “0”, and “0” to ““ 20 ”is assigned. Therefore, by managing the number of symbols that have been rotated since the reel index was detected, by referring to the symbol arrangement table, the position of the symbol that exists mainly in the middle of the display window and the type of the symbol can be determined. It can always be managed.

[Design combination table]
The symbol combination table will be described with reference to FIG. In the present embodiment, when the symbol combination displayed by each reel 120L, 120C, 120R along the winning determination line matches the symbol combination defined by the symbol combination table, it is determined to be a prize, Benefits based on the results of pachislot games such as medal payout, replay operation, and bonus game operation are given to the player.

  The symbol combination table defines a symbol combination, a display combination, and a payout number that are predetermined according to the type of privilege. The display combination is data for identifying a combination of symbols displayed along the winning determination line.

  The display combination is represented as 1-byte data in which a unique symbol combination is assigned to each bit. For example, when the symbol “bell” of each reel 120L, 120C, 120R is displayed along the winning determination line, “bell (00000010)” is determined as the display combination.

  Further, when a numerical value of 1 or more is determined as the payout number, medals are paid out. In the present embodiment, when a cherry, bell, or watermelon is determined as a display combination, medals are paid out. The number of payouts is defined according to the number of inserted sheets. Basically, a larger number of paid-out sheets is determined when the number of inserted sheets is small.

  In addition, when replay is determined as the display combination, replaying is performed. When BB is determined as the display combination, the bonus is activated. If the symbol combination displayed along the winning determination line does not match any of the symbol combinations defined by the symbol combination table, it is a so-called “losing”.

[Bonus operating table]
With reference to FIG. 18, the bonus operation time table will be described. The bonus operation time table defines data to be stored in various storage areas provided in the main RAM 63 when the bonus operation is performed.

  The in-operation flag is data for identifying the type of bonus that is activated. In the present embodiment, BB (a combination continuous action device related to a first type special combination) and RB (a first type special combination) are provided as bonus types. The operation of RB is continuously performed while the operation of BB is performed.

  The operation of BB is ended when the medals that have reached the prescribed number are paid out. The operation of the RB is ended when a game that reaches the specified number of times is performed, when there is a winning that reaches the specified number of times, or when the operation of the BB ends. The bonus end number counter, the possible game number counter, and the possible winning number counter are data for managing whether or not the specified number of times or the specified number of times as a trigger end timing of the bonus has been reached.

  More specifically, numerical values defined by the bonus operation time table are stored in the respective counters, and the subtraction is performed through the operation of the bonus. As a result, the operation of the corresponding bonus is completed on condition that the value of each counter is updated to “0”.

[Internal lottery table] / [Internal winning combination determination table]
[Internal lottery table]
The internal lottery table will be described with reference to FIGS. 19 and 20. The internal lottery table defines a data pointer and a lottery value according to the winning number. The data pointer is data acquired as a result of lottery performed with reference to the internal lottery table, and is data for designating an internal winning combination defined by an internal winning combination determination table described later. The data pointer is provided with a small role / replay data pointer and a bonus data pointer.

  In the present embodiment, random numbers extracted from a predetermined numerical range “0 to 65535” are sequentially subtracted by lottery values corresponding to each winning number, and whether or not the result of the subtraction is negative ( An internal lottery is performed by determining whether or not a so-called “digit” has occurred.

  Therefore, the larger the numerical value defined as the lottery value, the higher the probability that the data (that is, the data pointer) to which it is assigned is determined. The winning probability of each winning number can be represented by “the lottery value corresponding to each winning number / the number of all random numbers that may be extracted (65536)”.

  FIG. 19 shows an internal lottery table for a general gaming state. FIG. 20 shows the internal lottery table for RB operation. In the present embodiment, depending on the situation such as whether or not the bonus is activated, the type of internal winning combination and the winning probability that are determined are varied by using different types of internal lottery tables. , The expectation that the player holds is undulating.

[Internal winning combination determination table]
The internal winning combination determination table will be described with reference to FIGS. 21 and 22. The internal winning combination determination table defines an internal winning combination in accordance with the data pointer. When the data pointer is determined, the internal winning combination is uniquely acquired.

  The internal winning combination is data for identifying a combination of symbols of each of the reels 120L, 120C, and 120R that is permitted to be displayed along the winning determination line. Like the display combination, the internal winning combination is represented as 1-byte data in which a unique symbol combination is assigned to each bit. When the data pointer is “0”, the content of the internal winning combination is “lost”, which indicates that any display of symbol combinations defined by the symbol combination table described above is not permitted.

  FIG. 21 shows a small winning combination / replay internal winning combination determining table. The small winning combination / replay internal winning combination determination table defines an internal winning combination relating to the payout of medals or an internal winning combination relating to the operation of replay. FIG. 22 shows a bonus internal winning combination determination table. The bonus internal winning combination determination table defines internal winning combinations related to the operation of the bonus.

[Configuration of storage area provided in main RAM]
This completes the description of the contents of the data table stored in the main ROM. Next, the configuration of various storage areas provided in the main RAM will be described with reference to FIGS.

[Internal winning combination storage area] / [Cover holding combination storage area]
[Internal winning combination storage area]
With reference to FIG. 23, the configuration of the internal winning combination storing area will be described. The internal winning combination storing area stores the internal winning combination represented by the above-mentioned 1-byte data. When the bit is set to “1”, display of the corresponding symbol combination is permitted. When all bits are “0”, the content is lost.

  The main RAM is provided with a display combination storage area in which the display combination is stored. The configuration of the display combination storing area is the same as the configuration of the internal winning combination storing area. When “1” is set in the bit, the corresponding symbol combination is displayed along the winning determination line.

[Coverage storage area]
With reference to FIG. 24, the structure of the carryover combination storage area will be described.

  As a result of the aforementioned lottery, when an internal winning combination relating to the operation of the bonus is determined, this is stored in the carryover combination storage area. The internal winning combination (hereinafter referred to as the carryover combination) related to the operation of the bonus stored in the carryover combination storage area is retained without being cleared until the corresponding symbol combination is displayed on the winning determination line. It has become. And while the carryover combination is stored in the carryover combination storage area, it is stored in the internal winning combination storage area regardless of the result of the lottery described above.

[Operation flag storage area]
With reference to FIG. 25, the configuration of the operating flag storage area will be described.
The operating flag storage area stores an operating flag consisting of 1 byte. The operating flag has a unique bonus assigned to each bit. When “1” is set in the bit, the corresponding bonus is activated. The state when all bits are “0” is defined as a general gaming state.

[Program flow executed in pachislot]
This completes the description of the configuration of the various storage areas provided in the main RAM 63 (FIG. 4). Next, the contents of the program executed by the main CPU 61 of the main control circuit 50 will be described with reference to FIGS.

[Main flowchart by control of main CPU of main control circuit]
First, with reference to FIG. 26, a main flowchart by the control of the main CPU 61 will be described. When power is turned on to the pachi-slot 10, first, the main CPU 61 performs an initialization process (S1).

  Next, the main CPU 61 clears the designated storage area in the main RAM 63 (S2). For example, data stored in a storage area that needs to be erased for each game, such as an internal winning combination storage area or a display combination storage area, is cleared.

  Next, the main CPU 61 performs medal acceptance / start check processing which will be described later with reference to FIG. 27 (S3). In this process, input checks of the medal sensor 31 and the start switch 110 are performed.

  Next, the main CPU 61 extracts a random value and stores it in a random value storage area provided in the main RAM 63 (S4). Next, the main CPU 61 performs an internal lottery process which will be described later with reference to FIG. 28 (S5). In this process, the internal winning combination is determined by lottery based on a random value. Next, the main CPU 61 transmits a start command to the sub control circuit 80 (S6). The start command includes a parameter for specifying an internal winning combination.

  Next, the main CPU 61 requests the start of rotation of all reels 120L, 120C, 120R (S7). When the start of rotation of all reels 120L, 120C, and 120R is requested, the stepping motors 71L, 71C, and 71R are driven by an interrupt process (FIG. 33 described later) that is executed at a constant cycle (1.1173 msec). Controlled, rotation of each reel 120L, 120C, 120R is started.

  Next, the main CPU 61 performs a reel stop control process which will be described later with reference to FIG. 29 (S8). In this process, the input of the stop switch 112S is checked, and the rotation of the reel is stopped based on the timing when the stop buttons 112L, 112C, and 112R are pressed and the internal winning combination.

  Next, the main CPU 61 searches for a combination of symbols displayed along the winning determination lines 126a to 126e, and determines a payout number or the like based on the result (S9). As a result of the search, when the symbol combination displayed along the winning determination lines 126a to 126e matches the symbol combination defined by the symbol combination table, the corresponding display combination and the number of payouts are determined. Next, the main CPU 61 transmits a display command to the sub control circuit 80 (S10). The display command includes parameters that specify the display combination, the number of payouts, and the like.

  Next, the main CPU 61 performs medal payout processing (S11). Based on the determined payout number, the hopper 150 is driven and the credit number is updated. Next, the main CPU 61 updates the bonus end number counter based on the payout number (S12). The numerical value determined as the payout number is subtracted from the bonus end number counter.

  Next, the main CPU 61 determines whether or not the bonus operating flag is on (S13). When determining that the bonus operating flag is on, the main CPU performs a bonus end check process which will be described later with reference to FIG. 31 (S14). It is checked whether or not to end the bonus operation with reference to various counters for managing the bonus end timing.

  The main CPU 61 performs a bonus operation check process which will be described later with reference to FIG. 30 after S14 or when it is determined in S13 that the bonus operating flag is not on (S15). In this process, it is checked whether or not the bonus operation is started.

  Next, the main CPU 61 performs identification information reading result check processing (S16). In this process, the main CPU 61 checks the reading results from the non-contact IC tags 401 and 601 stored in the main RAM 63 (FIG. 13). This read result is stored in the main RAM 63 as information from the information reading devices 501 and 701 in an input port check process (S162) of an interrupt process (FIG. 31) described later.

  The main CPU 61 determines whether or not at least one of the reading results of the information reading devices 501 and 701 read from the main RAM 63 is warning information (S17). If a negative result is obtained in this step S17, this means that there is no warning state, that is, that the legitimate identification information has been correctly read from the non-contact IC tags 401 and 601 in the information reading devices 501 and 701. The main CPU 61 returns to S2 and repeats the same processing. As described above, when the regular case 310 (the regular main board 301) is attached to the cabinet 20 and the front door 30 is closed, it is necessary to limit the progress of the game or to issue a warning notification. Since there is no game, these processes are not executed, and the progress of the game is continued.

  On the other hand, if a positive result is obtained in step S17, this indicates a warning state, that is, reading from the non-contact IC tag 401 or 601 in at least one of the information reading devices 501 or 701. Means that the received information is not legitimate identification information or that the information reading device 501 or 701 has failed to read the identification information from the non-contact IC tag 401 or 601, and the main CPU 61 starts from step S 17. The process moves to step S18, and a warning process described later with reference to FIG. 32 is executed. This warning process limits the progress of the game, and a predetermined warning notification is given on the liquid crystal display device 210, the lamp 212, the speaker 214, and the like. When this process ends, the main CPU 61 proceeds to S2.

[Medal reception / start check processing]
Next, with reference to FIG. 27, the medal acceptance / start check process will be described. First, the main CPU 61 determines whether or not the automatic insertion counter is 0 (S31). When it is determined that the automatic insertion counter is 0, the medal passage permission is performed (S32). The solenoid of the selector 31 is driven, and the passage of medals in the selector 31 is prompted.

  When determining that the automatic insertion counter is not 0, the main CPU 61 copies the automatic insertion counter to the insertion number counter (S33). Next, the main CPU 61 clears the automatic insertion counter (S34). S33 and S34 are processes for replaying.

  After S32 or S34, the main CPU 61 sets 3 as the maximum value of the insertion number counter (S35). Next, the main CPU 61 determines whether or not the bonus operating flag is on (S36). When determining that the bonus operating flag is on, the main CPU 61 changes the maximum value of the insertion number counter (S37). For example, the maximum value is changed to 2.

  The main CPU 61 determines whether or not the passage of medals has been detected after S37 or when it is determined in S36 that the bonus operating flag is not on (S38). When determining that the passage of medals has been detected, the main CPU 61 determines whether or not the inserted number counter has reached the maximum value (S39). When determining that the insertion number counter has not reached the maximum value, the main CPU 61 adds 1 to the insertion number counter (S40). Next, the main CPU 61 stores 5 in the valid line counter (S41). Next, the main CPU 61 transmits a medal insertion command to the sub control circuit (S42). The medal insertion command includes a parameter for specifying the number of inserted coins.

  When the main CPU 61 determines in S39 that the inserted number counter is the maximum value, the main CPU 61 adds 1 to the credit counter (S43). The main CPU 61 checks the bet switch 132S after S43, after S42, or when it is determined that the passage of medals is not detected in S38 (S44). A numerical value corresponding to the bet button 132 is added to the inserted number counter while being subtracted from the credit counter.

  Next, the main CPU 61 determines whether or not the insertion number counter has reached the maximum value (S45). When it is determined that the insertion number counter has not reached the maximum value, the process proceeds to S38, whereas when it is determined that the insertion number counter has reached the maximum value, it is determined whether or not the start switch is on (S46). .

  When determining that the start switch is not on, the main CPU 61 proceeds to S38, whereas when determining that the start switch is on, the main CPU 61 prohibits medal passage (S47). The selector solenoid is not driven, and medals are expelled. When this process ends, the main CPU 61 ends the medal acceptance / start check process.

[Internal lottery processing]
Next, the internal lottery process will be described with reference to FIG. First, the main CPU 61 as a winning combination determining means determines an internal lottery table and the number of lotteries (S71). The operating flag storage area is referred to, and the internal lottery table and the number of lotteries are determined according to whether or not the bonus is activated. The number of lotteries indicates the number of times that a lottery value is subtracted and a determination is made as to whether a digit has occurred for each winning number defined by the internal lottery table.

  Next, the main CPU 61 obtains a random value stored in the random value storage area and sets it as a random number for determination (S72). Next, the main CPU 61 sets 1 as the initial value of the winning number (S73).

  Next, the main CPU 61 refers to the internal lottery table and acquires a lottery value corresponding to the winning number (S74). Next, the main CPU 61 subtracts the lottery value from the determination random number value (S75). Next, the main CPU 61 determines whether or not a digit has been made (S76). When the main CPU 61 determines that the digit is not set, the main CPU 61 subtracts 1 from the number of lotteries and adds 1 to the winning number (S77).

  Next, the main CPU 61 determines whether or not the number of lotteries is 0 (S78). When the main CPU 61 determines that the number of lotteries is not 0, the process proceeds to S64. On the other hand, when the number of lotteries is determined to be 0, the main CPU 61 sets 0 as a small role / replay data pointer and serves as a bonus data pointer. 0 is set (S79).

  When the main CPU 61 determines in S76 that a digit has been made, the main CPU 61 obtains a small role / replay data pointer and a bonus data pointer according to the current winning number (S80). After S80 or S79, the main CPU 61 refers to the small winning combination / replay internal winning combination determination table and acquires the internal winning combination based on the small winning combination / replay data pointer (S81).

  Next, the main CPU 61 stores the acquired internal winning combination in the internal winning combination storing area (S82). Next, the main CPU 61 determines whether or not the data stored in the carryover combination storage area is 0 (S83). When the main CPU 61 determines that the data stored in the carryover combination storage area is 0, the main CPU 61 refers to the bonus internal winning combination determination table and acquires the internal winning combination based on the bonus data pointer (S84). ). Next, the main CPU 61 stores the acquired internal winning combination in the carryover combination storing area (S85).

  After determining that the data stored in the carryover combination storage area is not 0 after S85, the main CPU 61 calculates the logical sum of the carryover combination storage area and the internal winning combination storage area, and the result Is stored in the internal winning combination storing area (S86). That is, the internal winning combination relating to the bonus operation is carried over. When this process ends, the internal lottery process ends.

[Reel stop control process]
Next, the reel stop control process will be described with reference to FIG. First, the main CPU 61 as stop control means determines whether or not an effective stop button 112L, 112C, 112R has been pressed (S101). When the main CPU 61 determines that the effective stop buttons 112L, 112C, and 112R are not pressed, the main CPU 61 stands by until it is pressed.

  When the main CPU 61 determines that the valid stop buttons 112L, 112C, and 112R have been pressed, the main CPU 61 invalidates the operation of the corresponding stop button (S102). The valid and invalid states of the stop buttons 112L, 112C, and 112R are managed in a predetermined storage area provided in the main RAM 63.

  Next, the main CPU 61 sets 5 as the number of checks (S103). In the present embodiment, since the maximum number of sliding pieces is set to “4”, when the stop button 112L, 112C, 112R is pressed, the position of the symbol in the middle stage of the corresponding display window is included, and then 4 Up to the position of the individual symbol is the target of the check. That is, any of the five numerical values “0”, “1”, “2”, “3”, and “4” is determined as the number of sliding frames.

  Next, based on the internal winning combination, the main CPU 61 determines the number of checks including the position of the symbol in the middle of the corresponding display window (hereinafter referred to as stop start position) when the stop button 112L, 112C, 112R is pressed. Among the positions of the symbols within the range, the position of the symbol with the highest priority is searched (S104). In this process, the position of the symbol that can display the combination of symbols permitted to be displayed by the internal winning combination along the winning determination line is determined as the position of the symbol with the highest priority.

  Next, the main CPU 61 determines the number of sliding symbols based on the search result (S105). The number of symbols from the stop start position to the symbol position with the highest priority is determined as the number of sliding symbols. Next, the main CPU 61 proceeds to wait for a scheduled stop position (S106). When a transition is made to waiting for the planned stop position, the driving of the stepping motor is controlled by an interrupt process to be described later, and the corresponding reels 120L, 120C, 120R are waited for the position of the symbol with the highest priority to reach the middle stage of the corresponding display window. The rotation of is stopped.

  Next, the main CPU 61 transmits a reel stop command to the sub control circuit 80 (S107). The reel stop command includes a parameter for specifying the type of the stopped reel.

  Next, the main CPU 61 determines whether or not there are stop buttons 112L, 112C, and 112R whose operations are valid (S108). That is, it is determined whether there is a reel that is still rotating. When the main CPU 61 determines that there are stop buttons 112L, 112C, and 112R that are effective in operation, the main CPU 61 proceeds to S101, while when it determines that there are no stop buttons 112L, 112C, and 112R that are effective in operation, Exit.

[Bonus activation check process]
Next, the bonus operation check process will be described with reference to FIG. First, the main CPU 61 determines whether or not the display combination is BB (S121). When the main CPU 61 determines that the display combination is BB, the main CPU 61 refers to the bonus operation time table and performs the BB operation processing (S122). In this process, the BB operating flag is turned on, and a predetermined value is set in the bonus end number counter.

  Next, the main CPU 61 clears the carryover combination storage area (S123). Next, the main CPU 61 transmits a bonus start command to the sub-control circuit (S124). When this process ends, the bonus operation check process ends.

  When determining that the display combination is not BB in S121, the main CPU 61 determines whether or not the display combination is replay (S125). When determining that the display combination is replay, the main CPU 61 copies the value of the insertion number counter to the automatic insertion counter (S126).

  When determining that the display combination is not replay in S125, the main CPU 61 determines whether or not the BB operating flag is on (S127). When the main CPU 61 determines that the BB operating flag is not on, the main CPU 61 ends the bonus operation check process. On the other hand, when the main CPU 61 determines that the BB operating flag is on, whether or not the RB operating flag is on. Is determined (S128).

  When the main CPU 61 determines that the RB in-operation flag is on, the main CPU 61 ends the bonus operation check process. On the other hand, when the main CPU 61 determines that the RB in-operation flag is not on, the main CPU 61 refers to the bonus operation time table. Time processing is performed (S129). In this process, the RB operating flag is turned on, and predetermined values are set in the winning possible number counter and the possible gaming number counter. When this process ends, the bonus operation check process ends.

[Bonus end check process]
Next, the bonus end check process will be described with reference to FIG. First, the main CPU 61 determines whether or not the bonus end number counter is 0 (S141). When determining that the bonus end number counter is 0, the main CPU 61 performs BB end time processing (S142). In this process, the BB operating flag and the RB operating flag are turned off, and various counters for managing the end timing of the bonus are cleared. Next, the main CPU 61 transmits a bonus end command to the sub-control circuit (S143). When this process ends, the bonus end check process ends.

  When the main CPU 61 determines that the bonus end number counter is not 0 in S141, the main CPU 61 updates the winning possible number counter or the possible gaming number counter (S144). The possible game number counter is decremented by 1, and when there is a win, the possible pay number counter is decremented by one. Next, the main CPU 61 determines whether or not the winning possible number counter or the possible gaming number counter is 0 (S145).

  When the main CPU 61 determines that the winning count counter or the possible game count counter is not 0, the main CPU 61 ends the bonus end check process, whereas when determining that the winning count counter or the possible game count counter is 0, Processing at the end of RB is performed (S146). In this process, the RB operating flag is turned off, and the winning possible number counter and the possible gaming number counter are cleared. When this process ends, the bonus end check process ends.

[Warning]
Next, warning processing will be described with reference to FIG. First, the main CPU 61 saves the register (S151), and then transmits a warning notification command to the sub-control circuit 80. As a result, the sub control circuit 80 stores the warning notification command in the message queue (S304), and performs a predetermined warning notification in accordance with the warning notification command stored in the message queue.

  Further, the main CPU 61 executes a game stop process (S153). In this game stop process, the main CPU 61 prohibits acceptance of operations of various operation means (the bet button 132, the start lever 110, the stop buttons 112L, 112C, and 112R). Thereby, in the state where it can be determined that the normal identification information cannot be correctly read from the non-contact IC tag 401 (that is, the state where the normal main board 301 is not attached), the progress of the game is stopped. The game will be limited.

  In this way, when a predetermined warning notification and game stop processing are executed, for example, when the legitimate main board 301 is removed illegally or replaced with another board, the game progresses. Is stopped, and a predetermined warning notification is performed.

  In the case of the present embodiment, a predetermined operation procedure for canceling the warning processing state (game stop, warning notification) is set in advance. For example, when a specific operation such as maintaining the start lever 110 in a predetermined direction for a predetermined time or more is performed, the main CPU 61 obtains an affirmative result in step S154, thereby causing the sub control circuit 80 to Then, the warning notification release command is transmitted to cancel the previous warning notification state (S155), and further the operation stop state is canceled by receiving the operation input of various operation means (S156). Then, after restoring the register (S157), the main CPU 61 ends the warning process and returns to S2 of the main flowchart shown in FIG.

[Interrupt processing under the control of the main CPU (1.1173 msec)]
Next, an interrupt process (1.1173 msec) controlled by the main CPU 61 will be described with reference to FIG. First, the main CPU 61 saves a register (S161). Next, the main CPU 61 performs an input port check process (S162). In this process, signals input from various switches such as a stop switch are checked. In this process, the main CPU 61 checks the reading result of the identification information of the non-contact IC tag 401 in the information reading device 501. This read result is stored in the main RAM 63 (FIG. 14). Based on the stored read result, the warning process described above with reference to FIG. 32 is executed, and the main board communication task process performed by the sub CPU described later In FIG. 34, when the information is read out to the sub control circuit 80 and warning notification is required, a predetermined warning notification processing is executed in the effect registration task processing by the sub CPU in FIG. The information reading device 501 periodically outputs the result of reading the identification information from the non-contact IC tag 401 to the main control circuit 50 (described later).

  Next, the main CPU 61 performs a reel control process (S163). In this process, the driving of the stepping motors 71L, 71C, and 71R is controlled so that when the start of rotation of all the reels 120L, 120C, and 120R is requested, the rotation of each reel is started and then rotated at a constant speed. Is done. In addition, when the number of sliding pieces is determined, the driving of the stepping motors 71L, 71C, 71R is controlled so that the rotation of the corresponding reel is continued for the number of sliding pieces and the rotation is decelerated and stopped. .

  Next, the main CPU 61 performs a lamp and 7-segment driving process (S164). Next, the main CPU 61 restores the register (S165). When this process ends, the interrupt process ends.

[Main board communication task]
With reference to FIG. 34, the main board communication task performed by the sub CPU 81 will be described. First, the sub CPU 81 performs a reception check on the command transmitted from the main control circuit (S301). Next, when receiving a command, the sub CPU 81 extracts the type of the command (S302).

  Next, the sub CPU 81 determines whether or not a command different from the previous one has been received (S303). If the sub CPU 81 determines that a command different from the previous command has not been received, the process proceeds to S301. On the other hand, if the sub CPU 81 determines that a command different from the previous command has been received, the sub CPU 81 stores the command in the message queue (S304). The received command includes a warning notification command notified from the main control circuit 50 based on the reading result of the identification information from the non-contact IC tags 401 and 601.

[Direction registration task]
Next, an effect registration task performed by the sub CPU 81 will be described with reference to FIG. First, the sub CPU 81 extracts a message from the message queue (S311). Next, the sub CPU 81 determines whether there is a message (S312). When the sub CPU 81 determines that there is a message, it copies the game information from the message (S313). For example, various data such as an internal winning combination, a type of reel that has stopped rotating, a display combination, an operating flag, and the like specified by parameters are copied to a storage area provided in the sub-RAM.

  Next, the sub CPU 81 performs an effect content determination process which will be described later with reference to FIG. 36 (S314). In this process, depending on the type of the received command, the contents of the effect are determined and the effect data is registered.

  The sub CPU 81 registers animation data after S314 or when it is determined that there is no message in S312 (S315). Next, the sub CPU 81 registers sound data (S316). Next, the sub CPU 81 registers lamp data (S317). The registration of animation data, the registration of sound data, and the registration of lamp data are performed based on the effect data registered in the effect content determination process. When this process ends, the process proceeds to S311.

  In this processing, the sub CPU 81 includes the warning notification command notified from the main control circuit 50 based on the reading result of the identification information from the non-contact IC tags 401 and 701 in the message taken out from the message queue. In this case, the sub CPU 81 registers warning notification data in the animation data registration processing (S315), registers warning notification data in the sound data registration processing (S316), and lamp data registration processing (S316). In S317), warning notification data is registered. As a result, the liquid crystal display device 210 gives a warning notification by characters or the like, the speaker 214 gives a warning notification by a warning sound or the like, and the lamp 212 gives a warning notification by blinking in a predetermined pattern.

[Production content decision processing]
Next, a flowchart of effect content determination processing executed by the sub CPU 81 as effect content determination means will be described with reference to FIG. First, the sub CPU 81 determines whether or not it is a start command reception time (S321). When determining that the start command is received, the sub CPU 81 extracts the effect random number, determines the effect number by lottery based on the internal winning combination, and registers it (S322). The production number is data for designating production contents to be executed this time.

  Next, the sub CPU 81 registers the production data at the start based on the registered production number (S323). The effect data is data that designates animation data, sound data, and lamp data. When the effect data is registered, corresponding animation data and the like are determined, and effects such as video display are executed. When this process ends, the effect content determination process ends.

  Next, when determining that the start command is not received, the sub CPU 81 determines whether or not the reel stop command is received (S324). If the sub CPU 81 determines that the reel stop command is received, the sub CPU 81 registers the stop effect data based on the registered effect number and the type of the stop button (S325). When this process ends, the effect content determination process ends.

  Next, when determining that the reel stop command is not received, the sub CPU 81 determines whether or not the display command is received (S326). When determining that the display command is being received, the sub CPU 81 registers the display effect data based on the registered effect number (S327). When this process ends, the effect content determination process ends.

  Next, when determining that the display command is not received, the sub CPU 81 determines whether or not the bonus start command is received (S328). If the sub CPU 81 determines that the bonus start command has been received, the sub CPU 81 registers the bonus start effect data (S329). When this process ends, the effect content determination process ends.

  Next, when determining that the bonus start command is not received, the sub CPU 81 determines whether or not the bonus end command is received (S330). When the sub CPU 81 determines that the bonus end command is not received, the sub CPU 81 ends the effect content determination process. On the other hand, if the sub CPU 81 determines that the bonus end command is received, the sub CPU 81 registers the bonus end effect data (S331). . When this process ends, the effect content determination process ends.

[Information reading process]
Next, with reference to FIG. 37, a flowchart of information reading processing in the information reading device 501 (FIGS. 8 to 10) provided in the cabinet 20 of the pachislot 10 will be described. This information reading process is a process that is always executed by the information reading device 501 and reads the identification information from the non-contact IC tag 401 of the case 310 (FIGS. 4 and 5) in which the main board 301 is accommodated in a non-contact manner. It is processing.

  First, the control unit 511 (FIG. 10) of the information reading device 501 determines whether or not a predetermined time has passed by an internal counter (S341). When it is determined that the predetermined time has elapsed, the control unit 511 moves the process from step S341 to step S342, and reads the identification information via the antenna coil 503 (FIG. 10).

  In this reading process, the control unit 511 determines whether or not the regular case 310 is attached based on the reception level detected by the reception demodulation unit 515. That is, in the present embodiment, the position of the protruding portion 315 (that is, the attachment position of the non-contact IC tag 401) in the case 310 (FIGS. 4 and 5) is accurately defined. For example, as shown in FIG. In addition, when the case 310E having a different position of the protruding portion 315 is attached, the position of the antenna coil 503 of the information reading device 501 and the position of the antenna coil 403 of the non-contact IC tag 401 on the case 310E side are shifted.

  In this case, the induced electromotive force generated in the coil is proportional to the change per unit time of the magnetic flux passing through the coil, and the reception obtained by the information reading device 501 is reduced by reducing the magnetic flux passing through the antenna coils 403 and 503. The level is also reduced. Thereby, the control unit 511 determines whether or not the reception level is equal to or higher than a preset threshold value (S343). If the reception level is equal to or higher than the threshold value, there is a possibility that the regular case 310 is attached. In this case, the process proceeds from step S343 to step S344, and it is determined whether or not the received identification information is regular identification information. Incidentally, the control unit 511 stores regular identification information in the internal memory in advance.

  If an affirmative result is obtained here, this means that regular identification information has been received, and the control unit 511 shifts the processing from step S344 to step S345 to the main control circuit 50. Notifies the normal state (that the correct identification information has been correctly received).

  On the other hand, if a negative result is obtained in step S343 described above, this means that a case 310E in which the reception level is not equal to or higher than the threshold and the position of the protruding portion 315 is different may be attached. The control unit 511 moves the process from step S343 to step S346, and notifies the main control circuit 50 of an error state (identification information has not been received correctly).

  If a negative result is obtained in step S344 described above, this means that although the reception level is equal to or higher than the threshold, the read identification information is not regular identification information. In other words, this means that the attached case (main board 301) may not be a regular one. In this case, the control unit 511 moves the process from step S344 to step S346, and notifies the main control circuit 50 of an error state (the read information was not legitimate identification information).

  Thus, the information reading apparatus 501 determines whether or not the attached case 310 (main board 301) is legitimate by executing the information reading process shown in FIG. The control circuit 50 can be notified.

[Information reading process]
Next, with reference to FIG. 39, a flowchart of information reading processing in the information reading device 701 (FIGS. 11 to 13) provided in the cabinet 20 of the pachislot 10 will be described. This information reading process is a process that is always executed by the information reading device 701, and is a process of reading identification information from the non-contact IC tag 601 of the front door 30 (FIG. 3) in a non-contact manner.

  First, the control unit 711 (FIG. 13) of the information reading device 701 determines whether a predetermined time has passed by an internal counter (S351). When it is determined that the predetermined time has elapsed, the control unit 711 moves the process from step S351 to step S352, and reads the identification information via the antenna coil 703 (FIG. 13).

  In this reading process, the control unit 711 determines whether a signal from the non-contact IC tag 601 is received based on the reception level detected by the reception demodulation unit 715. That is, when the front door 30 is not closed, the positions of the antenna coil 703 of the information reading device 701 and the antenna coil 603 of the non-contact IC tag 601 on the front door 30 side are shifted.

  In this case, the induced electromotive force generated in the coil is proportional to the change per unit time of the magnetic flux passing through the coil, and the reception obtained by the information reading device 701 is reduced by reducing the magnetic flux passing through the antenna coils 603 and 703. The level is also reduced. Accordingly, the control unit 711 determines whether or not the reception level is equal to or higher than a preset threshold value (S353). If the reception level is equal to or higher than the threshold value, the front door 30 may be closed. In this case, the process proceeds from step S353 to step S354, and it is determined whether or not the received identification information is regular identification information. Incidentally, the control unit 711 stores regular identification information in the internal memory in advance.

  If an affirmative result is obtained here, this means that regular identification information has been received, and the control unit 711 moves the process from step S354 to step S355 to the main control circuit 50. Notify that the door is closed.

  On the other hand, if a negative result is obtained in step S353 described above, this means that the reception level is not equal to or higher than the threshold value, and the front door 30 may be opened. Then, the process moves from step S353 to step S356, and the main control circuit 50 is notified that the door is open.

  If a negative result is obtained in step S354 described above, this means that although the reception level is equal to or higher than the threshold value, the read identification information is not regular identification information. That is, some signal is received, but the signal may not be from a regular non-contact IC tag 601. In this case, the control unit 711 moves the process from step S354 to step S356 and notifies the main control circuit 50 that the door is open.

  Thus, the information reading device 701 can determine whether or not the front door 30 is closed by executing the information reading process shown in FIG. 39, and notify the main control circuit 50 of the result.

[Operation and Effect of Embodiment]
In the configuration described above, the pachi-slot 10 detects whether or not the case 310 containing the regular main board 301 is attached by the non-contact IC tag 401 and the information reading device 501 as identification information reading means. Has been made.

  The antenna coil 403 of the non-contact IC tag 401 is provided at the tip of the protruding portion 315 formed on the case 310. As described above, the tip of the projecting portion 315 is provided on the main substrate 301 because it is separated from the main substrate 301 accommodated in the case 310 in a direction perpendicular to the substrate surface. The distance from the circuit element increases. Thereby, the influence by the circuit element of the main board | substrate 301 can be suppressed with respect to the electromagnetic conversion characteristic produced between the antenna coils 403 and 503. FIG.

  Further, in case 310, at least a portion including protruding portion 315 (a portion to which non-contact IC tag 401 is attached) is formed of resin, so that deterioration of electromagnetic conversion characteristics can be suppressed.

[Other embodiments]
In the above-described embodiment, the proximity type non-contact information tags 401 and 601 using electromagnetic coupling and the proximity type information reading devices 501 and 701 for reading information are described.
