The front door 5 is configured to open the lower door 8 and then open the upper door 7. A display window 10 is provided in the upper door 7, and a first reel 12 a, a second reel 12 b, and a third reel 12 c are rotatably incorporated in the back of the display window 10. As is well known, various patterns are arranged on the outer periphery of the first to third reels 12a to 12c at a constant pitch, and three patterns per reel are observed through the corresponding display window 10 when the reels are stopped. It has come to be. An LCD panel 13 is disposed on the side of the display window 10. The LCD panel 13 is provided for performing an effect by displaying an image or a moving image for effect during a game.

  An operation panel 15 is provided on the lower door 8 below the display window 10 and the LCD panel 13. In addition to the MAX bet button 16 and the 1 bet button 17, the operation panel 15 locks the front door 5 in addition to various operation buttons such as the stop buttons 18a to 18c, the start lever 19, and the payout button 20. A key insertion hole 21 for inserting a key is provided. The operation panel 15 below the LCD panel 13 is provided with a medal slot 23 for inserting gaming medals. Since the functions of these operation buttons and start lever 17 are well known, the details are omitted. Further, below the operation panel 15, a medal outlet 26 and a medal tray 27 for paying out a payout number of game medals when a game is won in the slot machine 2 and a prize is obtained. Is provided.

  As shown in FIG. 2, a reel unit 30 is placed on the upper part in the housing 3. The reel unit 30 is a unit in which the first to third reels 12a to 12c are united together with each stepping motor. The motor driving board on which an IC for driving and stopping control of each stepping motor is mounted, and each reel is rotating. A photo sensor for detecting the passage of the signal piece provided at the reference position of the reel is also incorporated. A control circuit device 32 for controlling the operation of each part of the slot machine 2 is assembled at the rear part of the reel unit 30.

  A hopper device 33 and a power supply device 34 are placed in the lower part of the housing 3. The hopper device 33 operates when a game is obtained in the slot machine 2 and a prize is obtained, and a game medal corresponding to the prize is paid out to the medal tray 27. A storage tank 35 for storing game medals inserted from the medal insertion slot 23 is provided at the top of the hopper device 33.

  On the rear surface of the upper door 7, a display unit 36 that controls the LCD panel 13 is incorporated in the upper part of the display window 10. A selector 38 to be described later is provided on the back surface of the lower door 8 and below the medal slot 23. Further, the left side plate 3a in front of the housing 3 is provided with bearing portions 40 that rotatably support the upper door 7 and the lower door 8 with a predetermined interval. On the right side plates 7a, 8a in front of the upper door 7 and the lower door 8, a rotation shaft 41 inserted through the bearing portion 40 is provided at a position corresponding to the bearing portion 40. The rotation shaft 41 is connected to the bearing portion 40. The upper door 7 and the lower door 8 are assembled so as to be freely opened and closed. The left side plate 8 b of the lower door 8 is provided with a locking device 45 that is a locking means for locking the lower door 8. When locking the lower door 8, the lower door 8 is closed after the upper door 7 is closed, and the protrusion 43 provided on the right side plate 3 b of the housing 3 and the fixing plate 46 constituting the locking device 45 are provided. When the locking claw is engaged, the lower door 8 is locked. That is, the lower door 8 is not opened unless the engagement of the locking claw is released by operating the locking device 45. On the other hand, the upper door 7 is not provided with the locking device 45 as described above, but is locked by the engagement of the locking claw like the lower door 8, and the upper door 7 is pulled by pulling a locking / unlocking lever (not shown). It can be opened. If the lower door 8 is closed after the upper door 7 is closed, the upper door 7 can be opened without locking the upper door 7 because the tongue 7b provided on the upper door 7 is covered with the lower door 8. It will never be done.

  As shown in FIG. 3, the locking device 45 includes a fixed plate 46, a coil spring 47, a key cylinder 48, and the like. At one edge portion of the fixed plate 46, hooking claws 50 having hooks at the tips are formed at two locations, upper and lower. Further, a connecting piece 51 and a mounting piece 53 are formed to protrude from the opposite edge portion where the locking claw 50 is provided. On one side surface of the fixed plate 46, a restricting piece 52 is provided so as to protrude. As shown in the figure, elongated holes 46a are formed on the upper and lower sides of the fixed plate 46, respectively, and the mounting position is adjusted by sandwiching a spacer (not shown) between the fixed plate 46 and the left side plate 8b of the lower door 8. Then, the pin 55 is fixed to a stop hole (not shown) formed in the left side plate 8b of the lower door 8 through the long hole 46a. Thereby, the fixed plate 46 is slidably attached in the vertical direction. As shown in FIG. 2, the fixing plate 46 is disposed with the tip of the locking claw 50 facing the inside of the housing 3.

  The key cylinder 48 is fixed to the back side of the key insertion hole 21 provided in the operation panel 15. On the rear surface of the key cylinder 48, a rotation shaft that rotates in conjunction with the operation of the key 56 inserted into the key cylinder 48 through the key insertion hole 21 is provided. The connecting member 60 is crimped to the rotating shaft. In the connecting member 60, connecting portions 60a and 60b are formed at two positions at a predetermined pitch interval, and the connecting piece 51 enters between the connecting portions 60a and 60b. As a result, when the key 56 is rotated counterclockwise (A direction in the figure), the connecting portion 60a presses the connecting piece 51 downward (C direction in the figure), and the fixing plate 46 has a locking claw. 50 and slide 43 are disengaged (see FIG. 6). When the key 56 is rotated clockwise (B direction in the figure), the connecting portion 60b presses the connecting piece 51 upward (D direction in the figure), and the fixing plate 46 is connected to the locking claw 50. It slides to the engagement position (refer FIG. 5) which the protrusion 43 engages.

  The attachment piece 53 is provided below the fixed plate 46, and one end of the coil spring 47 is attached to the attachment piece 53. An attachment piece 54 is also provided inside the left side plate 8 b of the lower door 8, and the other end of the coil spring 47 is attached. Therefore, the coil spring 47 always applies an urging force in the upward direction that engages the locking claw 50 with the protrusion 43. In other words, in the present embodiment, when the lower door 8 is closed, the closed state is maintained unless the key 56 is unlocked by the biasing force of the coil spring 47. That is, it is configured to be held locked.

  A solenoid 62 that restricts the fixed plate 46 from sliding to the release position is provided below the key cylinder 48. The operation of the solenoid 62, which is a part of the unlocking restricting means, is controlled by a CPU described later. When the upper door 7 and the lower door 8 are closed and the lower door 8 is locked, the solenoid 62 is deenergized. Therefore, the driving iron core 65 protrudes from the bobbin 63, and the driving iron core 65 and the regulating piece 52 come into contact with each other. Accordingly, the movable plate 65 restricts the fixed plate 46 from sliding from the engagement position to the release position. Further, when the fixing plate 46 is slid from the engagement position to the release position, a magnetic field is generated by a coil (not shown) wound in the bobbin 63 when the CPU energizes the solenoid 62. The driving iron core 65 is drawn into the bobbin 63. As a result, the drive iron core 65 is retracted from the lower portion of the restricting piece 52, and the fixing plate 46 is allowed to slide from the engagement position to the release position.

  As shown in FIG. 4, the selector 38, which is a discriminating means, includes a medal passage 70, a guide plate 71, a first medal sensor 72, a second medal sensor 73, and the like. The medal passage 70 includes a vertical path 75, an inclined path 76, and a curved path 77. The vertical path 75 communicates with a guide passage that guides the gaming medal inserted from the medal slot 23 to the selector 38, and drops the gaming medal in the vertical direction. The ramp 76 rolls the gaming medal that has fallen from the vertical path 75 diagonally downward. The curved path 77 has a substantially U-shape, and changes the traveling direction of the gaming medal that has rolled on the inclined path 76 to the right by approximately 90 degrees to guide the gaming medal to the storage tank 35. .

  The medal passage 70 has a lower passage width wider than an upper passage width. Therefore, the game medal that has rolled from the vertical path 75 rolls on the inclined road 76 in a state inclined from the standing state. A guide plate 71 that forms part of the upper side of the ramp 76 is provided on the upper side parallel to the ramp 76. The guide plate 71 has one end surface 71a, a shaft portion 80, and the other end surface 71b provided with a medal sorting solenoid and a spring (not shown). The medal sorting solenoid is controlled by a CPU provided in the control circuit device 32.

  As shown in FIG. 4, the guide plate 71 guides the game medal with the shaft portion 80 as a rotation fulcrum by the exciting action of the medal sorting solenoid and the restoring force of the spring, and the game medal on the ramp 76. It is provided so as to be freely rotatable between the discharge positions where it is dropped off. When a game medal is inserted, the medal selection solenoid is turned on, and the excitation action works, so that the guide plate 71 is biased toward the wall surface of the ramp 76 as shown by the solid line in the figure. Become. Further, one end surface 71a of the guide plate 71 guides the outer diameter edge portion of the game medal that rolls through the inclined path 76. At this guide position, the game medal rolls between the wall surface of the ramp 76 and one end 71 a of the guide plate 71. At this time, one end 71a of the guide plate 71 guides the outer diameter edge of the game medal slightly regulated. Further, when the credit is added up to the upper limit, or when the game is being executed, the medal selection solenoid is turned off, and the guide plate 71 at the guide position is inclined by the restoring force of the spring as shown by the dotted line in the figure. It rotates to the discharge position which leaves | separates from the wall surface of 76. As a result, the gaming medal rolling from the vertical path 75 to the inclined path 76 is not guided by the guide plate 71, and thus falls off the inclined path 76 in the direction of the arrow due to the weight of the medal. It is dropped from between the passage covers 81 (see FIG. 2) provided in the discharge port 26 and discharged from the discharge port 26. Further, when an improper medal (fake) having an outer diameter or thickness that is either larger or smaller than the outer diameter or thickness of a regular gaming medal is inserted, even if the guide plate 71 is in the guide position, Since the guide cannot be correctly guided, the irregular medal falls between the selector 38 and the passage cover 81 and is discharged from the discharge port 26.

  A first medal sensor 72 and a second medal sensor 73 are provided on the wall surface of the ramp 76. The first and second medal sensors 72 and 73 are, for example, reflection type photoelectric sensors integrally including a light projecting unit and a light receiving unit, and the first medal sensor 72 and the second medal are sequentially arranged from the vertical path 75 side. The sensors 73 are provided in this order. When the game medal passes through the slope 76, if the light path of the light projecting portion of the first medal sensor 72 or the second medal sensor 73 is blocked, the light projected from the light projecting portion is reflected on the game medal. When this reflected light is received by the light receiving unit, the photoelectric sensor is turned on. Thereby, the gaming medals inserted by the control circuit device 32 are counted based on the detection signal in which the first and second medal sensors 72 and 73 are simultaneously turned on.

  The slot machine 2 includes a solenoid 62 that is an unlocking restricting means, a transmission / reception antenna 86, and a reading means for restricting or permitting the sliding of the fixing plate 46 and preventing unauthorized unlocking of the lower door 8. An RFID reader / writer (R / W) 87 and the like are provided.

  In order to allow the fixed plate 46 to slide, an identification medal 85 is inserted from the medal insertion slot 23. The identification medal 85 is a game medal provided with a wireless non-contact ID tag (RFID tag) 89 as an identification information storage medium. That is, the game medal and the identification medal 85 have the same diameter. The RFID tag 89 includes a coiled antenna 90 and an IC chip 91 connected to the antenna 90. The IC chip 91 is provided with a memory capable of recording various kinds of information and a communication circuit for communicating with the RFID R / W 87 via the transmission / reception antenna 86, and identification information is stored in the memory. Since the RFID tag 89 is very thin, the identification medal 85 in which the RFID tag 89 is incorporated and the game medal are substantially the same. Therefore, due to the shape of the identification medal 85, the identification medal 85 is not dropped from the ramp 76 of the selector 38 and falls to the discharge port. In addition, since the outer diameter and thickness of the identification medal 85 are substantially the same as those of the game medal, it is preferable that the color of the identification medal 85 is different from the color of the game medal.

  The transmission / reception antenna 86 is provided on the wall surface of the vertical path 75 of the selector 38 and is connected to the RFID R / W 87. The transmission / reception antenna 86 accumulates radio waves received from the RFID R / W 87 as electric power by electromagnetic induction, and operates the IC chip 91 of the RFID tag 89 using this as energy. The RFID R / W 87 reads information stored in the IC chip 91 and writes new information to the IC chip 91.

  As shown also in FIG. 5, the control circuit device 32 is provided with a CPU 93 as a control means, an EEPROM 95 as a storage means, and a timer 96 as a time measuring means. The CPU 93 executes control processing for each unit of the slot machine 2. The EEPROM 95 stores various data processed by the CPU 93 and registration information.

  When the identification medal 85 provided with the RFID tag 89 is inserted from the medal insertion slot 23, the identification medal 85 passes through the front surface of the transmission / reception antenna 86 provided on the vertical path 75. At this time, the identification information stored in the RFID tag 89 is read out to the RFID R / W 87 via the transmission / reception antenna 86. The read identification information and registration information stored in advance in the EEPROM 95 are sent by the CPU 93 to the collation unit 96 (collation means). In the collation unit 96, the identification information and the registration information are collated.

  When the identification information matches the registration information, the collation unit 97 outputs an unlock signal to the CPU 93. In response to this unlock signal, the CPU 93 causes the timer 96 to start measuring a predetermined time. Further, the CPU 93 energizes the solenoid 62 for a predetermined time that is counted. As a result, as shown in FIG. 6, the driving iron core 65 of the solenoid 62 is pulled into the bobbin 63, so that the fixing plate 46 is engaged with the rotation of the key 56 in the counterclockwise direction (A direction in the figure). Slide from the alignment position to the release position (see FIG. 6) in the direction C in the figure. Thereby, since the engagement of the latching claw 50 and the projection 43 is released and unlocked, the lower door 8 can be opened. When the lower door 8 is opened, the fixing plate 46 is slid again to the upper engagement position by the inelastic force of the torsion spring 47.

  When the timer 96 finishes counting the predetermined time, the CPU 93 stops energizing the solenoid 62 and resets the timer 96. As a result, the driving iron core 65 that has been drawn into the bobbin 63 protrudes again and comes into contact with the regulating piece 52 provided on the fixed plate 46. Therefore, if the rotation operation with the key 56 is not performed within a predetermined time, the lower plate 8 cannot be unlocked because the fixing plate 46 is restricted from sliding to the release position by the driving iron core 65.

  When the identification information does not match the registration information, and when a medal (for example, a game medal) for which no identification information is recorded is inserted, the timer 96 does not measure the predetermined time, and the solenoid 62 Since the energization is also stopped, the driving iron core 65 is in contact with the restricting piece 52 while protruding from the bobbin 63 (see FIG. 5). Thereby, even if the rotation operation with the key 56 is performed, the lower plate 8 cannot be unlocked because the fixing plate 46 remains restricted to slide to the release position.

  Further, when the identification medal 85 passes through the front surface of the transmission / reception antenna 86 of the vertical path 75, the CPU 93 sends insertion history information to the RFID R / W 87. The RFID R / W 87 writes the input history information into the memory of the IC chip 91 provided in the RFID tag 89 via the transmission / reception antenna 86. The insertion history information is, for example, the date and time when the identification medal 85 is inserted into the slot machine 2. By reading this input history information from the IC chip 91 of the RFID tag 89, it is possible to confirm when the front door 5 is opened.

  When the identification information is read from the identification medal 85, the CPU 93 sends a discharge signal to the selector 38 regardless of whether or not the read identification information matches the registered information. In response to the discharge signal, the selector 38 turns off the power supply to the medal selection solenoid. As a result, the guide plate 71 moves to the discharge position, and the identification medal 85 that has rolled from the vertical path 75 to the inclined path 76 falls off the inclined path 76 without being guided by the guide plate 71 at the top. The dropped identification medal 85 falls between the selector 38 and the passage cover 81 and is discharged from the discharge port 26. When a game medal is inserted from the medal slot 23, the identification information is not read even if the game medal passes through the vertical path 75 of the selector 38, so that the guide plate 71 remains in the guide position. In this way, the slope 76 rolls and is guided to the storage tank 35.

  Next, the operation of the slot machine 2 configured as described above will be described. In order to change the game settings of the slot machine 2 or adjust various devices, it is necessary to unlock the lower door 8 and open the front door 5 in the order of the lower door 8 and the upper door 9. In this case, the operator of the game hall unlocks the lower door 8 using the key 56 and the identification medal 85. As shown in the flowchart of FIG. 7, first, an identification medal 85 in which identification information is recorded is inserted from the medal insertion slot 23. The inserted identification medal 85 passes through the vertical path 75 communicating with the medal slot 23. At this time, the identification information stored in the RFID tag 89 provided on the identification medal 85 is read by the RFID R / W 87 via the transmission / reception antenna 86 provided on the vertical path 75, and the IC chip of the RFID tag 89 is read. In 91, the date and time when the identification medal 85 is inserted is recorded as the insertion history information. When the identification information is read out by the RFID R / W 87, the CUP 93 turns off the medal selection solenoid and moves the guide plate 71 from the guide position to the discharge position. Then, since the identification medal 85 that has passed through the vertical path 75 and rolled to the ramp 76 is not guided by the guide plate 71, the identification medal 85 falls off the ramp 76 and is discharged from the discharge port.

  The read identification information is sent to the verification unit 97. In the collation unit 97, the identification information and the registration information recorded in the EEPROM 95 are collated. When the identification information matches the registration information, the timer 96 starts measuring a predetermined time. The CPU 93 energizes the solenoid 62 only for a predetermined time that is counted. Accordingly, the driving iron core 65 that has been in contact with the restriction piece 52 is retracted from the lower portion of the restriction piece 52. When the key 56 inserted into the key insertion hole 21 is rotated counterclockwise, the fixing plate 46 slides from the engagement position to the release position, and the engagement between the locking claw 50 and the projection 43 is released, so that the lower door 8 is moved. Unlocked. The front door 5 is opened by opening the upper door 7 after opening the lower door 8.

  If the identification information and the registration information do not match, as shown in FIG. 5, the driving iron core 65 that is in contact with the restriction piece 52 of the fixed plate 46 is not retracted from under the restriction piece 52. Even when the key 56 inserted into the hole 21 is rotated counterclockwise, the driving iron core 65 restricts the sliding of the fixed plate 46 to the lower release position. Thereby, the lower door 8 is not unlocked. Therefore, even if an attempt is made to open the front door 5 using only the illegally acquired key 56, it will not be opened.

  Further, in the above embodiment, when the identification information matches the registration information, a predetermined time is counted, and the fixing plate 46 is allowed to slide for the predetermined time. However, as shown in the flowchart of FIG. When the information matches the registered information, the fixed plate 46 may be allowed to slide regardless of the predetermined time.

  In this case, when the identification medal 85 is inserted and the read identification information matches the registered information, the solenoid 62 is energized and the driving iron core 65 is drawn into the bobbin 63. Therefore, the fixing plate 46 is allowed to slide in order for the driving iron core 65 to retreat from under the restriction piece 52 provided on the fixing plate 46. When the rotation operation by the key 56 is performed, the fixing plate 46 slides to the release position, so that the projection 43 and the engagement claw 50 are disengaged and the lower door 8 is unlocked. If the identification information does not match the registration information, the driving iron core 65 is not pulled into the bobbin 63, and the sliding of the fixing plate 46 remains restricted, so the lower door 8 is not unlocked.

  In the above embodiment, the insertion history information when the identification medal 85 is inserted is written in the memory of the IC chip 91 of the RFID tag 89 provided in the identification medal 85. However, the present invention is not limited to this, and is provided in the slot machine 2. The input history information may be written in the EEPROM 95 provided. Alternatively, the worker may carry an identification medal individually and provide identification information for each worker. In this case, registration information corresponding to the identification information provided individually is stored in the EEPROM 95. Thereby, when writing the insertion history information in the EEPROM 95, it is possible to confirm when and when the lower door 8 is opened by writing the input date and time and the individual identification information. Can be prevented and detected.

  In addition, the identification information and registration information corresponding to the identification information are recorded in advance in the RFID tag 89 and the EEPROM 95 of the identification medal 85. However, the present invention is not limited to this, and the identification information is recorded on the RFID tag 89 by the RFID R / W 87. You may write. In this case, the identification information written in the RFID tag 89 is sent to the CPU 93. The CPU 93 records this identification information in the EEPROM 95 as registration information. Thereby, when the identification medal 85 is lost or stolen, the identification information and the registration information can be easily changed. Therefore, even if the illegally acquired identification medal 85 is used, the new identification information and By changing to registered information, the front door 5 is not unlocked illegally.
