In this state, the detected part 180a of the movable piece 180 does not enter between the light projecting part and the light receiving part of the detection part 183a, and the light irradiated from the light projecting part of the detection part 183a to the light receiving part may be blocked. Therefore, the passage of medals is not detected by the detector 183.

  On the other hand, as shown in FIG. 6B, when the medal flows down in the direction from the medal insertion unit 4 side toward the hopper tank 34a, and passes the position corresponding to the insertion medal sensor 31b in the medal receiving flow path 29b. In other words, the movable piece 180 is operated so that the medal comes into contact with the tip portion 180b of the movable piece 180 and the tip portion 180b is withdrawn from the medal receiving passage 29b. Then, as the movable piece 180 is operated along with the passage of the medal, the detected portion 180a provided at the end of the movable piece 180 enters between the light projecting portion and the light receiving portion of the detecting portion 183a, and the light is projected. By blocking the light irradiated from the head to the light receiving portion, the passage of the medal is detected by the detector 183.

  Further, when the medal passes the position corresponding to the inserted medal sensor 31b in the medal receiving flow path 29b, the medal contacts the movable piece 180 to operate the movable piece 180. At this time, the frictional force with the movable piece 180 and the urging force by the urging member 181 that urges the movable piece 180 act on the medal, and the flow-down deceleration of the medal is a speed equal to or less than a predetermined value. To slow down. Further, as shown in FIGS. 4 and 5, the movable piece 180 of the inserted medal sensor 31b is disposed on the medal insertion unit 4 side, that is, on the upstream side from the detection range A of the inserted medal sensors 31a to 31c, and receives the medal receiving unit. The medal flowing down the flow path 29b is decelerated to a speed equal to or lower than a predetermined value, and then flows down to the detection range A.

  Further, as shown in FIG. 6C, an object such as a medal (a medal or an illegal instrument used for fraud (for example, a medal attached with a thread or an object resembling a medal)) is on the hopper tank 34a side. In the case of a reverse flow from the medal insertion part 4 side, even if an object such as the medal contacts the movable piece 180, the movable piece 180 does not operate, and the medal passes through the tip 180b of the movable piece 180. The movable piece 180 is restricted from moving from the movable piece 180 to the medal insertion unit 4 side with respect to an object such as a medal that is in contact with the movable piece 180. It has become. The movable piece 180 is arranged so that the medal is positioned within the detection range A of the inserted medal sensors 31a to 31c when restricting the movement of the backward flowing medal, and the movement is restricted by the movable piece 180. Objects such as medals are detected by inserted medal sensors 31a and 31c.

  7A is a cross-sectional view taken along the line DD in FIG. 4A in the medal selector 29, and FIG. 7B is a side view of the medal selector 29 from the direction E in FIG. 4A. .

  As shown in FIG. 7A, the inserted medal sensors 31a and 31c are formed in a substantially concave shape, a light projecting portion is provided on one end side of the concave portion, a light receiving portion is provided on the multi-end side, and the light projecting portion side is provided. The medal selector 29 is arranged so that one end and one end on the light receiving unit side are positioned on the side surface of the medal receiving channel 29b. When the medal is positioned within the detection range A of the inserted medal sensors 31a to 31c, or when the medal flows backward and the movement is restricted by the movable piece 180 (see, for example, FIG. 5A), the medal is Positioned between one end on the light projecting unit side and one end on the light receiving unit side, the end of the medal and the end of the inserted medal sensors 31a and 31c can be in contact with each other. Since one end on the light projecting unit side and one end on the light receiving unit side of the inserted medal sensors 31a and 31c are positioned on the side surfaces of the medal receiving channel 29b, the medal in the medal receiving channel 29b is tilted and the medal receiving channel is received. Returning the medal by going out of the path 29b or tilting an improper instrument inserted into the medal receiving flow path 29b and used for fraud (for example, a medal attached with a thread or an object resembling a medal) It can prevent taking out from the flow path 29c.

  Further, as shown in FIG. 7B, an outlet through which the medal can flow out from the medal receiving flow path 29b inside the main body part to the outside on the hopper tank 34a is provided on the left side wall of the main body part of the medal selector 29. 142 is provided. The outlet 142 is formed in a rectangular shape having a width slightly wider than the thickness of the medal. When the medal flows down the outlet 142 and flows out to the hopper tank 34a, the medal is the inner surface of the outlet 142, that is, the medal. The wall of the selector 29 can be contacted, and the medal is prevented from tilting. Further, when the medal flows backward in the outlet 142 and the movement is restricted by the movable piece 180 (for example, see FIG. 5A), a part of the medal has entered the outlet 142. Thus, the medal is prevented from tilting. By preventing the medal from being tilted by the outflow port 142, the medal in the medal receiving channel 29b tilts and goes out of the medal receiving channel 29b, or is inserted into the medal receiving channel 29b. It is possible to prevent an illegal instrument from being tilted and taken out from the medal return channel 29c.

  Next, the medal backflow prevention device 48 in the medal selector 29 will be described with reference to FIG.

  The medal backflow prevention device 48 is provided inside the medal selector 29, is connected to the game control board 40, and is controlled by the main control unit 41 to an ON state (excited state) and an OFF state (non-excited state). The backflow prevention solenoid 48a (see FIG. 3), the movable piece 48b (see FIG. 8) that swings in conjunction with the excitation of the backflow prevention solenoid 48a and can move in and out of the medal receiving passage 29b, and the backflow prevention solenoid 48a are turned off. In this state, a biasing member (not shown) that biases the movable piece 48b so as not to protrude into the medal receiving passage 29b is configured as a main member.

  As shown in FIG. 8A, the movable piece 48b has an object (such as a medal) whose movement is restricted by the movable piece 180 of the inserted medal sensor 31b when one end side of the movable piece 48b protrudes into the medal receiving passage 29b. For example, when there is a medal, an illegal instrument, etc.), it is provided at a position where it can contact an object such as the medal. Further, as shown in FIG. 8B, the movable piece 48b is urged so as not to protrude into the medal receiving passage 29b when the backflow prevention solenoid 48a is controlled to be in an OFF state (non-excited state). When the backflow prevention solenoid 48a is energized by a member (not shown) and the backflow prevention solenoid 48a is in the OFF state, the medal inserted from the medal insertion portion 4 flows down through the medal receiving passage 29b and flows out from the outlet 142. It has come to be.

  On the other hand, as shown in FIG. 8C, when the backflow prevention solenoid 48a is controlled to be in an ON state (excited state), the movable piece 48b has a predetermined direction (an arrow in FIG. 8C). A one end side of the movable piece 48b is projected into the medal receiving flow path 29b by being rotated in the A direction), and an object such as a medal is received by the medal receiving flow path 29b by the one end side of the projected movable piece 48b. The inside is prevented from moving backward from the outflow port 142 side to the medal insertion part 4 or the medal return channel 29c side.

  Specifically, as shown in FIG. 8D, when the medal flowing down the medal receiving flow path 29b flows backward and the movement of the medal is restricted by the movable piece 180 of the insertion medal sensor 31b, the backflow prevention solenoid 49a. Is controlled to be in the ON state, one end side of the movable piece 48b projects into the medal receiving flow path 29b, and the medal is received by the clamping surface 48c of the movable piece 48b and the wall 29b 'on the opposite side of the medal receiving flow path 29b. It is designed to be pinched. Further, when a medal is sandwiched between the movable piece 48b and the wall 29b ′ of the medal receiving flow path 29b on one end side of the movable piece 48b that can project into the medal receiving flow path 29b, the outer peripheral surface of the medal is A contact portion 48d that can be contacted is formed, and when the clamped medal moves backward, the contact portion 48d comes into contact with the outer edge portion of the medal to restrict the movement of the medal. Yes. Similarly to the case where the medal flows backward in the medal receiving flow path 29b, the backflow prevention solenoid 49a is also turned on when the illegal instrument inserted into the medal receiving flow path 29b and used for fraudulent action is flowed back. By being controlled, the unauthorized piece is sandwiched between the movable piece 48b and the wall 29b ′ of the medal receiving passage 29b to restrict the movement.

  Thus, the movable piece 48b projects into the medal receiving flow path 29b when the backflow prevention solenoid 48a is controlled to be in the ON state (excited state), and the medal receiving flow path 29b is formed by the clamping surface 48c and the contact portion 48d. By preventing the backflow of an object such as a medal, it is possible to prevent the object such as the medal from being taken out from the medal insertion unit 4 or the medal return channel 29c.

  Next, a main process executed by the main control unit 41 as a basic process and a game start waiting process executed in the main process will be described with reference to FIGS.

  The main control unit 41 of this embodiment repeatedly loops the process according to the control state until the detection state of the various switches connected to the game control board 40 changes as the main process, and the detection state of the various switches A process of shifting in stages according to changes is executed. The main process is repeatedly executed for each unit of game, and one period of the main process corresponds to one unit of game.

  Further, the main control unit 41 executes a timer interrupt process (main) at regular time intervals (about 0.56 ms in this embodiment). Note that the execution interval of the timer interrupt process (main) is set to a time longer than the sum of the time taken to repeat the process repeated in accordance with the control state in the main process and the execution time of the timer interrupt process (main) Therefore, the process that is repeated according to the control state between the current and next timer interrupt processes (main) is completed at least once. In addition, the timer interrupt process (main) is based on input status data (input data indicating the current input status of various switches) based on the input status of various switches and sensors input to the input port of the main control unit 41. , Update data indicating that the previous and current input data are in the same state, and edge data indicating that the determined data has changed from the previous time) and updating the RAM 41c to a predetermined area, or main processing to update the RAM 41c. A process of outputting a drive control signal for driving the reel motors 32L, 32C, 32R and the flow path switching solenoid 30 based on predetermined data set in the predetermined area is included.

  In the main process, a game start waiting process for waiting until the game is started, an internal lottery process for performing an internal lottery in accordance with the start of the game, and a reel control for performing control for rotating and stopping the reels 2L, 2C, and 2R The game end setting process for performing various settings when the process, all the reels 2L, 2C, 2R are stopped and the game is ended is repeatedly executed sequentially. In the game start waiting process in the main process, the main control unit 41 performs a process of changing the ON / OFF setting of the flow path switching solenoid 30 when a predetermined condition is satisfied as described later. In the internal lottery process, the reel control process, and the game end setting process, the process for changing the ON / OFF setting of the flow path switching solenoid 30 is not performed.

  In the game start wait process executed in the main process, various processes from the end of the previous game to the start of the next game are performed. In the game start wait process, first, the game display unit 13 is a process for setting the display of various indicators, etc., to the state at the start of the game, a process for determining whether or not the hopper tank 34a is in a full tank state, When the re-game player wins in the previous game, error processing is controlled to end the error state by shifting to the error state that disables the progress of the game, and the full state is released. Processing (not shown) for setting the number of bets necessary for giving and starting the next game is performed.

  Thereafter, as shown in FIG. 9, a single interrupt process is performed to wait until the timer interrupt process is performed once (Sa1), and various switches input to the input port of the main control unit 41 by the timer interrupt process. Wait until the input status data of the sensor etc. is updated.

  After the timer interrupt process is performed in step Sa1, reference is made to control state data that can specify the current set bet value, current credit value, etc., set in a predetermined area of the RAM 41c. Then, it is determined whether or not a medal can be inserted (Sa2).

  When it is specified that the number of bets is less than the prescribed number (3 in this embodiment) or the credit value is less than the maximum value (50 in this embodiment). It is determined that a medal can be inserted. Thereafter, whether or not ON edge data indicating that the confirmed data has changed from the OFF state to the ON state among the edge data included in the input state data set in the predetermined area of the RAM 41c is set for the insertion port sensor 26. Whether or not the insertion port sensor 26 has detected a medal is determined based on whether or not (Sa3).

  In step Sa3, when ON edge data is set for the insertion port sensor 26 and it is determined that the insertion port sensor 26 detects a medal, the flow path switching solenoid 30 set in a predetermined area of the RAM 41c. As a value of a control timer (hereinafter referred to as a flow path switching control timer), a predetermined value (a predetermined time in which it is estimated that the player does not continuously insert medals from the medal insertion unit 4, for example, A value corresponding to 10 seconds) is set to start measuring a predetermined time (Sa4), and then the flow path switching solenoid 30 is set to ON (Sa5).

  When the flow path switching solenoid 30 is set to ON, the main control unit 41 is turned on (predetermined driving voltage) with respect to the flow path switching solenoid 30 from a solenoid drive circuit (not shown) provided in the main control unit 41. ) Drive control signal is output. As a result, a predetermined voltage is applied to the flow path switching solenoid 30 and the energized state (excited state) is controlled.

  The channel switching control timer is updated by subtraction every time a timer interrupt process (main) is performed, and when the timer value becomes 0, it can be specified that a predetermined time has elapsed. In addition, the flow path switching control timer is determined to be in a state in which a medal can be inserted in the step Sa2 even during timing, and the insertion port sensor 26 is determined based on the ON edge data in the step Sa3. When it is determined that a predetermined value is detected, the predetermined value is set again in the step Sa4, so that the measurement of the predetermined time is newly started, and based on the timer value for flow path switching control. It is possible to specify whether or not a predetermined time has elapsed since the insertion port sensor 26 detected the medal last.

  In step Sa3, when ON edge data is not set for the insertion port sensor 26 and it is determined that the insertion port sensor 26 has not detected a medal, or in step Sa5, the flow path switching solenoid 30 is turned ON. After the setting, a medal insertion signal process for performing various processes based on the detection status of the inserted medal sensors 31a to 31c is performed (Sa6).

  In the medal insertion signal processing, transitions of detection signals of the insertion medal sensors 31a to 31c are predetermined transitions (for example, as shown in FIG. 10A, the insertion medal sensor 31b, the insertion medal sensor 31a, the insertion medal). The transition from the OFF state to the ON state in the order of the sensor 31c, or after the confirmed data of the inserted medal sensor 31b changes from the ON state to the OFF state, one of the inserted medal sensor 31a or the inserted medal sensor 31b is confirmed. From the ON state to the OFF state, the other determined data changes from the ON state to the OFF state, and then the determined data of the inserted medal sensor 31c matches the transition that changes from the ON state to the OFF state). To do. Further, when the detection state of at least one of the inserted medal sensors 31a, 31b, and 31c is turned on, an elapsed time from when the inserted medal sensors 31a, 31b, and 31c are turned on is calculated. A medal passage time timer for measurement is initialized and set to 0, and time measurement by the timer is started. The medal passage time timer is incremented and updated every time the timer interrupt process (main) is performed, and the elapsed time since the medal is detected by the inserted medal sensors 31a to 31c based on the timer value. The time, that is, the time during which medals pass the detection range A of the inserted medal sensors 31a to 31c can be specified.

  Then, based on the detection signals of the inserted medal sensors 31a to 31c and the medal passage time timer, the transition of the detection signal coincides with the predetermined transition, and a predetermined time range (a genuine medal is detected within the detection range A). In this embodiment, the time range is from 10.08 milliseconds to 99.68 milliseconds, and the time range is the detection range of the medal insertion sensors 31a to 31c. Based on the actual measurement value of the time required for passing the token, the shape of the medal receiving channel 29b of the medal selector 29, the arrangement of the inserted medal sensors 31a to 31c in the medal receiving channel 29b, the characteristics of the inserted medal sensors 31a to 31c, and the like. If it is determined that the medal has passed the detection range A of the inserted medal sensors 31a to 31c, the authentic medal It determined to have passed successfully, perform the medal insertion processing for adding the medals bet number or credit. In the medal insertion process, it is determined whether or not the bet amount has reached the specified number (3 in this embodiment) with reference to the currently set bet number stored in the predetermined area of the RAM 41c. If the bet number has not reached the specified number, 1 is added to the current bet number. Thus, one bet number is set in response to one medal being inserted from the medal insertion unit 4. Further, it is determined whether or not the bet number has reached the specified number (3 in this embodiment), and when it is determined that the specified number of bets has already been set, 1 is added to the credit counter. . As a result, one credit is added in response to the insertion of one medal from the medal insertion unit 4.

  On the other hand, based on the detection signals of the inserted medal sensors 31a to 31c, when the transition of the detection signal does not coincide with the predetermined transition or when the medal is less than the predetermined time range based on the medal passage time timer, When it is determined that the detection range A of the sensors 31a to 31c has passed, if it is not possible to specify that the medal has passed the detection range A even after the time exceeding the predetermined time range has elapsed, an abnormality related to the passage of the medal Is detected, and an error flag that can specify that an abnormality relating to the passage of medals has been detected is set in a predetermined area of the RAM 41c.

  As described above, the inserted medal sensor 31b includes the movable piece 180. When the medal flows backward from the hopper tank 34a side to the medal insertion portion 4 side, the movable piece 180 does not operate and the medal is not operated. Is restricted from moving to the medal insertion unit 4 side, and the medal is detected by the insertion medal sensor 31c. As described above, in the case where the medal flows backward and the movement of the medal insertion unit 4 is restricted by the movable piece 180, the transition of the detection state of the insertion medal sensors 31a to 31c is, for example, as shown in FIG. In addition, during the period in which the inserted medal sensors 31a and 31b are in the OFF state, only the inserted medal sensor 31c is in the ON state, or the inserted medal sensor 31c detects the medal and the detected state is in the ON state. Is out of the predetermined time range described above.

  On the other hand, in the medal insertion signal processing, as described above, when the detection state of at least one of the insertion medal sensors 31a, 31b, and 31c is turned on, the medal passage time timer is initialized to measure the time. When it is not possible to specify that the medal has passed the detection range A even if a time exceeding the predetermined time range has elapsed based on the medal passage time timer, it is determined that an abnormality relating to medal passage has been detected. Therefore, even when the movement of a medal or the like flowing backward in the medal inflow channel 29a is restricted by the movable piece 180, the time during which the detection state of the inserted medal sensor 31c or the inserted medal sensor 31a is in the ON state is the above-described time. By being out of the predetermined time range, it can be detected as an abnormality related to the passage of medals.

  Further, in the medal insertion signal process, when the transition of the detection signals of the insertion medal sensors 31a to 31c does not coincide with a predetermined transition, it is determined that an abnormality related to the passage of the medal is detected. As a transition of the detection signal of the inserted medal sensors 31a to 31c, for example, when a medal or the like flows backward in the medal inflow channel 29a, the inserted medal sensor 31b on the upstream side in the medal inflow channel 29a is turned on. Previously, an abnormality relating to the passage of medals can be detected when a transition in which the downstream inserted medal sensors 31a and 31c are in the ON state is specified.

  In the medal insertion signal processing, when an abnormality that may cause the medal or the like to flow backward in the medal inflow channel 29a is detected among the abnormalities related to the medal passage (for example, as described above, the insertion medal sensor When the time during which the detection states 31a to 31c are in the ON state is outside the predetermined time range, the inserted medal sensors 31a and 31c on the downstream side are turned on before the inserted medal sensor 31b on the upstream side. In the case of transition, etc.), an error flag (back flow) that can specify that there is a possibility that a medal or the like is flowing backward in the medal inflow channel 29a is set in a predetermined area of the RAM 41c as the above error flag. .

  Further, in the medal insertion signal process, the medal passage status in the detection range A of the insertion medal sensors 31a to 31c is determined based on the transition of the detection signals of the insertion medal sensors 31a to 31c. Then, as a result of the determination, medal passing state data that can specify whether the medal has not passed through the detection range, is in a passing state, or has passed has been stored in a predetermined area of the RAM 41c. Set.

  After performing the medal insertion signal processing in the step of Sa6, it is determined whether or not the error flag is set with reference to a predetermined area of the RAM 41c (Sa7). When the error flag is set, it is determined whether or not the error flag is an error flag (backflow), so that there is an abnormality that may cause a medal or the like to flow backward among the abnormalities related to the passage of medals. It is determined whether or not an occurrence has occurred (Sa8), and if it is determined that an abnormality that may have caused a reverse flow of medals or the like has occurred, the backflow prevention solenoid 48a is set to ON (Sa9). Then, after the backflow prevention solenoid 48a is set to ON in step Sa9, or if it is determined in step Sa8 that there is no abnormality that may cause a medal or the like to flow backward, error processing is performed ( Sa10).

  In the error process, after shifting to an error state that disables the progress of the game, the process waits until the reset / setting switch 38 or the reset switch 23 is turned on as a condition for canceling the error state. When the release condition is satisfied, the error prevention state is canceled and the error processing is terminated after the backflow prevention solenoid 48a is set to the OFF state regardless of whether or not the backflow prevention solenoid 48a is in the ON state. To do. After the error processing is finished, the medal insertion signal processing is performed again, and when an abnormality is detected in the transition of the detection signals of the insertion medal sensors 31a to 31c, the error processing is performed again.

  For example, when it is determined that an abnormality that may cause a medal or the like to flow backward has occurred, the backflow prevention solenoid 48a is controlled to be in the ON state and the front door is controlled in the error state. When 1b is opened and the reset / setting switch 38 or the reset switch 23 is operated without removing an object such as a medal sandwiched by the medal backflow prevention device 48 in the medal selector 29, the medal backflow prevention device 48 Regardless of whether or not an object such as a medal that has been clamped is removed, the backflow prevention solenoid 48a is controlled to be in the OFF state, and the error processing is ended. At this time, when an object such as a medal sandwiched by the medal backflow prevention device 48 is not removed while being controlled in the error state, the backflow prevention solenoid 48a is controlled to be in the OFF state, An object such as a medal is released from being held by the medal backflow prevention device 48. When an object such as a medal is an unauthorized instrument that is not a regular medal and the movement by the movable piece 180 of the inserted medal sensor 31b is restricted even after the holding by the medal backflow prevention device 48 is released. In this case, an abnormality is detected in the transition of the detection signals of the inserted medal sensors 31a to 31c by the medal insertion signal processing performed after the error processing is ended, and the error processing is performed again. On the other hand, when an object such as a medal sandwiched by the medal backflow prevention device 48 is removed when the error state is controlled, or when the medal backflow prevention device 48 is released from being held, When the object flows down to the outlet 142 side of the medal selector 29 and is taken into the slot machine 1, no abnormality is detected in the medal insertion signal processing performed after the error processing is completed. The error processing is not performed again.

  When it is determined that the error flag is not set in step Sa7, and after the error processing is ended in step Sa10, the medal passing state data set by the medal insertion signal processing and the current slot machine 1 credit value The final medal (the medal that will reach the maximum value (50 in this embodiment) by accepting the medal detected by the inserted medal sensors 31a to 31c and adding the credit) is accepted. It is determined whether it is in the middle (Sa11). In step Sa7, based on the medal passing state data, it is specified that the medal is passing through the detection range A of the inserted medal sensors 31a to 31c, and the current credit value is a value that is one less than the maximum value (this book In the embodiment, when 49) is specified, it is determined that the final medal is being received, and the flow path switching solenoid 30 is set to OFF (Sa12).

  When the flow path switching solenoid 30 is set to OFF, the main control unit 41 drives the flow path switching solenoid 30 in an OFF state (0 V) from a solenoid drive circuit (not shown) included in the main control unit 41. A control signal is output. As a result, no voltage is applied to the flow path switching solenoid 30 and the flow path switching solenoid 30 is controlled to a non-energized state (non-excited state).

  If it is determined in step Sa2 that it is not possible to insert a medal, if it is determined in step Sa11 that the final medal is not accepted, the number of wagers is set after the flow path switching solenoid 30 is set OFF in step Sa12. Operation to accept the operation of various switches according to the status of credit or credit, or the operation to accept the operation by the corresponding switch by identifying the operation of the switch for which the operation is enabled An input reception process is performed (Sa13).

  In the operation input acceptance process, when the medal is not passing based on the transition of the medal insertion signal and the credit value set in the predetermined area of the RAM 41c is 1 or more, the operation of the MAXBET switch 6 is performed. Enable acceptance. Further, when a medal is not passing based on the transition of the medal insertion signal, if the bet number set in the predetermined area of the RAM 41c is a specified number, the acceptance of the operation by the start switch 7 is validated. Further, when the medal is not passing based on the transition of the medal insertion signal, the acceptance of the operation by the settlement switch 10 and the setting key switch 37 is validated.

  In the operation input reception process, when the operation of the start switch 7 is detected in a state where the operation by the start switch 7 is valid, a start flag indicating that the start switch 7 has been operated is displayed in the main control unit 41. Setting to a predetermined register invalidates the acceptance of operation by the start switch 7. Further, when an operation by the settlement switch 10 is detected in a state where the operation by the settlement switch 10 is valid, a settlement flag indicating that the settlement switch 10 has been operated is set in a predetermined register of the main control unit 41. The reception of the operation by the settlement switch 10 is invalidated. Further, when an operation by the MAXBET switch 6 is detected in a state where the operation by the MAXBET switch 6 is valid, a MAXBET flag indicating that the MAXBET switch 6 has been operated is set in a predetermined register of the main control unit 41. , The acceptance of the operation by the MAXBET switch 6 is invalidated.

  After performing the operation input receiving process in the step of Sa13, whether or not the settlement switch 10 is operated based on the flag set in the predetermined register of the main control unit 41 (Sa14), the MAXBET switch 6 is operated. It is determined whether the start switch 7 has been operated (Sa16).

  In step Sa14, if it is determined that the settlement flag is set in the predetermined register and the settlement switch 10 is operated, the flow path switching solenoid 30 is set to OFF (Sa18), and is set by inserting a medal. A settlement process is performed for returning the medals for the number of bets and the medals for the credits stored to the player (Sa19).

  In the checkout process, after controlling the sub-control unit 91 to transmit a checkout command (start) that can specify that the checkout process is to be started, medals for the number of bets set by inserting medals and The hopper motor 34b is driven for a time corresponding to the total number of medals stored in the credits, and control is performed so that the medals corresponding to the number are returned from the medal payout opening 9. Then, after finishing returning the medals for the number of sheets, control is performed to transmit to the sub-control unit 91 a settlement command (end) that can specify that the settlement process is to be terminated, and the settlement process is terminated. To do.

  After the settlement process is performed in the step Sa19, a predetermined period (this embodiment) in which the sub-control unit 91 performs later-described settlement related notification in response to the settlement process performed by the main control unit 41. Then, the settlement related notification waiting process for 10 seconds is performed (Sa20). Then, after a predetermined period of time has elapsed, the process returns to the step Sa1 to perform a one-time interrupt process, and based on the input state data of various switches updated by the timer interrupt process (main) being performed. The process of step Sa16 is performed.

  In step Sa15, when it is determined that the MAXBET flag is set in the predetermined register and the MAXBET switch 6 is operated, a bet number setting process for setting a bet number using credits is performed (Sa21).

  In the betting number setting process, the number of medals up to a prescribed number within a possible range is set as the betting number based on the current credit value set in the predetermined area of the RAM 41c, and the number of medals set as the betting number is set. Process to subtract from credit. Thus, the bet amount is set using the credit based on the operation of the MAXBET switch 6 by the player. In the bet number setting process, when one or more bets are set using credits, a bet number setting flag indicating that the bet number is set is set in a predetermined register of the main control unit 41. Further, when one or more bets are set using credits, settings are made so that the 1 to 3 BETLEDs 14 to 16 corresponding to the set bets are turned on, and the display on the credit display 11 is a credit after subtraction. Set to be the value of.

  After performing the betting number setting process in the step of Sa21, it is determined whether or not the betting number is set by operating the MAXBET switch 6 based on whether or not the betting number setting flag is set in the predetermined register ( Sa22). If the bet number setting flag is set in the predetermined register and it is determined that the bet number has been set, the flow path switching solenoid 30 is set to OFF (Sa23).

  If it is determined in step Sa22 that the bet amount setting flag is not set in the predetermined register and the bet amount is not set by operating the MAXBET switch 6, the flow path switching solenoid 30 is turned off in step Sa19. After the setting, the process returns to the step Sa1 and waits for one interrupt, and the processing of the steps Sa2 to Sa16 is performed based on the input state data of various switches updated by the timer interruption processing (main). I do.

  In the step Sa16, when it is determined that the start flag is not set in the predetermined register and the start switch 7 is not operated effectively, the flow started in the step Sa4 with reference to the predetermined area of the RAM 41c. Based on the path switching timer, it is determined whether or not a predetermined time has elapsed since the insertion port sensor 26 last detected a medal (Sa24), and the flow path switching timer is 0 and the predetermined time has elapsed. If it is determined that the flow is switched, the flow path switching solenoid 30 is set to OFF (Sa25).

  When it is determined in step Sa24 that the flow path switching timer is not 0 and the predetermined time has not elapsed, and after the flow path switching solenoid 30 is set to OFF in step Sa25, the flow proceeds to step Sa1. Returning, the process of waiting for one interrupt is performed, and the processing of steps Sa2 to Sa16 is performed based on the input state data of various switches updated by the timer interrupt process (main).

  On the other hand, if it is determined in step Sa16 that the start flag is set in the predetermined register and the start switch 7 is effectively operated, a random number value for internal lottery is obtained from the random number circuit included in the main control unit 41. Then, a process for setting a predetermined area in the RAM 41c and various processes for starting a game when the start switch 7 is effectively operated are performed, the game start waiting process is terminated, and the process returns to the main process. Thereafter, in the main process, an internal lottery is performed by an internal lottery process using a random value acquired when a valid operation of the start switch 7 is detected in the game start waiting process, and an effective operation of the start switch 7 is performed. One game is started by the rotation of the reels 2L, 2C, 2R being started by the reel control process in response to the detection of.

  As described above, the main control unit 41 according to the present embodiment detects the effective operation of the start switch 7 in the state where the prescribed number of bets is set in the game start waiting process of the main process, After the switching solenoid 30 is set to OFF and controlled to a non-energized state (non-excited state), processing for starting a game is performed. Thus, after the game start waiting process, the flow path switching solenoid 30 is maintained in a non-energized state when the internal lottery process, the reel control process, and the game end time setting process are performed.

  Also, the main control unit 41 turns on the flow path switching solenoid 30 when a medal is inserted from the medal insertion unit 4 and detected by the insertion port sensor 26 in a state where the medal can be inserted in the game start waiting process. It is set to be controlled to the energized state. Thereby, the flow path switching plate 147 in the medal selector 29 is switched from the outflow position to the receiving position, and the medal inserted from the medal insertion unit 4 can be taken into the hopper tank 34a side.

  In addition, the main control unit 41 determines that a predetermined condition (determination that the final medal is being accepted, operation of the settlement switch 10, and setting of the bet number by the MAXBET switch 6 in the game start waiting process) When the start switch 7 is operated in a state where the specified number of bets is set, and a predetermined time has elapsed since the last medal is detected by the insertion slot sensor 26), the flow path is established. Regardless of whether the switching solenoid 30 is set to ON or OFF, the flow path switching solenoid 30 is set to OFF and controlled to a non-energized state.

  For example, as shown in FIG. 11, after one game is completed, a medal can be inserted during a period from when a medal is inserted through the medal insertion unit 4 until the insertion sensor 26 detects the medal ( Even if the number of bets is less than the prescribed number (3 in this embodiment) or the credit value is less than the maximum value (50 in this embodiment), the flow path switching solenoid 30 is Set to OFF. When the medal is detected by the insertion port sensor 26 in a state where the medal can be inserted, the flow path switching solenoid 30 is set to ON. Thereafter, until a predetermined condition (determined that the final medal is being received) is satisfied, the flow path switching solenoid 30 is maintained at the ON setting and is controlled to be in an energized state.

  Then, in the state where the flow path switching solenoid 30 is set to ON, medals are sequentially inserted from the medal insertion unit 4 so that the bet number reaches a specified number, and credits are added to the final medal. (The medal whose credit reaches the maximum value (50 in this embodiment by receiving the medal being detected by the inserted medal sensors 31a to 31c) is detected by the inserted medal sensors 31a to 31c. By determining that the final medal is being received, the flow path switching solenoid 30 is set to OFF and is controlled to be in a non-energized state.

  When the final medal is detected, after the flow path switching solenoid 30 is set to OFF, the number of bets has reached the specified number and the credit has reached the maximum value. When the medal is inserted from the medal insertion unit 4, the medal is returned from the medal payout opening 9.

  Further, for example, as shown in FIG. 12, in a state where a medal can be inserted after one game is finished, the medal is detected by the insertion port sensor 26, so that the flow path switching solenoid 30 is set to ON. After that, when a bet is set using credits by operating the MAXBET switch 6 in a state where a medal is inserted from the medal insertion unit 4 and a bet number less than the prescribed number is set, When the bet number is set by the MAXBET switch 6, the flow path switching solenoid 30 is set to OFF and is controlled to be in a non-energized state.

  After the bet number is set by using the credit by operating the MAXBET switch 6, at least the credit for the medal used for setting the bet number is vacant and the medal can be inserted. . In this state, it is established that the bet number is set by the MAXBET switch 6, and even after the flow path switching solenoid 30 is set to OFF, a medal is inserted from the medal insertion unit 4 and the medal is inserted. However, when the medal is detected by the insertion port sensor 26, the flow path switching solenoid 30 is set to ON again.

  The main control unit 41 according to the present embodiment is configured so that the credit value is increased when the MAXBET switch 6 is operated in a state where medals are inserted from the medal insertion unit 4 and a bet number less than the prescribed number is set. When the bet number cannot be set using credits or when a medal is inserted from the medal insertion unit 4 and a specified number of bets is set, the MAXBET switch 6 is operated, If the bet number cannot be set using credits, the bet number is not set by the MAXBET switch 6, so the flow path switching solenoid 30 is not set to OFF.

  Further, for example, as shown in FIG. 13, in a state where a medal can be inserted after one game is completed, the medal is detected by the insertion port sensor 26, so that the flow path switching solenoid 30 is set to ON. After that, when a medal is inserted further, the medal is detected by the insertion slot sensor 26 every time a medal is inserted. On the other hand, every time a medal is detected by the insertion port sensor 26, the main control unit 41 sets a predetermined value (for example, a value corresponding to 10 seconds) to the flow path switching control timer, The elapsed time since the last medal is detected by the sensor 26 is counted. Then, based on the flow path switching control timer, it is specified that a predetermined time (for example, 10 seconds) has passed since the last medal was detected by the insertion port sensor 26, so that the flow path switching solenoid 30. Is set to OFF and controlled to a non-energized state.

  A state in which a medal can be inserted even after the passage switching solenoid 30 is set to OFF after a predetermined time (for example, 10 seconds) has elapsed since the last medal was detected by the insertion port sensor 26. In this case, a medal is inserted from the medal insertion unit 4 and the medal is detected by the insertion port sensor 26, whereby the flow path switching solenoid 30 is set to ON again.

  Further, for example, as shown in FIG. 14, in a state where a medal can be inserted after one game is finished, the medal is detected by the insertion port sensor 26, so that the flow path switching solenoid 30 is set to ON. After that, when a medal is inserted from the medal insertion unit 4 and a predetermined number of bets are set, the start switch 7 is operated, so that the flow path switching solenoid 30 is set to OFF and the power is not supplied. It will be controlled by the state.

  Further, for example, as shown in FIG. 15, when the settlement switch 10 is operated in a state where a medal can be inserted after one game is finished, based on the operation of the settlement switch 10. Then, the flow path switching solenoid 30 is set to OFF and controlled to a non-energized state. Then, the main control unit 41 performs a settlement process, and drives the hopper motor 34b so as to return all the medals for the number of bets set and the medals for the credits. Thereafter, the setting of the flow path switching solenoid 30 is maintained in the OFF state, the settlement related notification waiting process is performed, and the process waits until a predetermined time (in this embodiment, 10 seconds) elapses. During the settlement process and during the settlement process, the main control unit 41 does not refer to the detection state of the insertion port sensor 26 and does not set the flow path switching solenoid 30 to ON, so that a medal is inserted from the medal insertion unit 4. Even in the case where the token is played, the medal is returned from the medal payout exit 9.

  After the settlement related notification waiting process is completed, the bet number is not set and no credit is stored, and the medal can be inserted, so that the medal is inserted from the medal insertion unit 4. Thus, when the medal is detected by the insertion port sensor 26, the flow path switching solenoid 30 is set to ON.

  On the other hand, the sub-control unit 91 issues a notification during settlement for notifying that the settlement process is being performed on the main control unit 41 side during the period in which the settlement process is being performed on the main control unit 41 side. It is possible to perform a settlement-related notification that performs a predetermined notification related to the settlement being performed during the period in which the settlement-related notification waiting process is performed on the main control unit 41 side. is there.

  By receiving the settlement command (start) from the sub-control unit 91 and the main control unit 41, the settlement command (end) is received when it is specified that the settlement process is started on the main control unit 41 side. Thus, during the period up to the time when it is specified that the settlement process is terminated on the main control unit 41 side, the notification during settlement is controlled. In the checkout notification control, the liquid crystal display 51 displays a checkout image indicating that the checkout process is being performed (for example, a character image of “Checkout in progress”). Further, a notification mode during settlement indicating that the settlement process is being performed for the effect effect LED 52 (for example, predetermined LEDs provided on the upper front side and the left and right ends of the slot machine 1 among the LEDs included in the effect effect LED 52 ( (Not shown) is controlled to flash in a red mode.

  After the notification during the settlement, the settlement is performed for a predetermined time (in this embodiment, the same 10 seconds as the settlement-related notification waiting process is performed on the main control unit 41 side). Checkout related notification for performing notification related to the event is performed. In the checkout related notification control, the checkout related notification image (for example, “Thank you for your hard work. The image for notifying the content related to the end of the game is displayed on the liquid crystal display 51. Further, the production effect LED 52 is controlled to a payment related notification mode (for example, a mode similar to the notification mode during payment) indicating that the payment related notification is being performed. Also, notification sounds related to the settlement (for example, “Thank you for your hard work. Please beware of forgotten things.” Etc.) to notify the contents related to the settlement being completed and the game being terminated. Are output from the speakers 53 and 54.

  The sub-control unit 91 may perform a game by performing an inter-game effect between games after performing the settlement-informing notification and the settlement-related notification in the same manner as before the settlement-informing notification is started. It is notified that it is in a possible state.

  In this way, the sub-control unit 91 performs the settlement-related notification for a predetermined time after performing the notification during the settlement, so that the settlement during the settlement and the settlement-related notification are combined for at least the predetermined time. Since the notification is made based on the fact that the slot machine 1 has been performed, the store clerk or the like of the store where the slot machine 1 is installed can recognize that the payment process has been performed in the slot machine 1. ing.

  As a conventional slot machine, in the energized state, the flow-down passage for medals inserted from the outside serves as an intake-side passage for taking in medals, and in the non-energized state, the flow-down passage includes a discharge-side passage for discharging medals to the outside. In order to achieve this, a flow path switching solenoid for switching the flow path of medals is provided, and this flow path switching solenoid is controlled to be energized when a medal can be inserted, while a medal cannot be inserted. There is a configuration that controls to a non-energized state when the state becomes unclear.

  In such a configuration, the flow path switching solenoid constituting the switching means for performing the operation of switching the flow-down path of the medal, which is the game medium, to the intake-side path and the discharge-side path is in a state where the medal can be inserted. The power is controlled from time to time, and when the medal cannot be inserted, it is controlled to the non-energized state. In the energized state, the flow path switching solenoid generates heat as a current corresponding to the applied voltage flows. However, when the medal can be inserted, the medal is not inserted. However, if the switching means continues to operate, the flow path switching solenoid may be deteriorated at an early stage due to being energized for a long time.

  On the other hand, in the slot machine 1 of this embodiment, the medal receiving flow path 29b for guiding the inserted medals to the hopper tank 34a side, and the medal return flow path for guiding the inserted medals to the medal payout outlet 9 side. 29c, a flow path switching plate 147 for switching the flow path so that the inserted medal flows into one of the medal receiving flow path 29b or the medal return flow path 29c, and a switching means for operating the flow path switching plate 147. A flow path switching solenoid 30 and a main control unit 41 capable of controlling the energization state / non-energization state of the flow path switching solenoid 30, and the main control unit 41 stores the inserted medal as a credit, The bet number is set by detecting a medal flowing down the medal receiving channel 29b, and the MAXBET switch 6 is operated by the player as a predetermined operation. The betting number can be set by using credits, and the flow path switching plate 147 is inserted when the flow path switching solenoid 30 is controlled to be in a non-energized state. In which the inserted medal flows into the medal receiving flow path 29b when the flow path switching solenoid 30 is controlled to be energized. The main control unit 41 is configured to be in a position at a position, and the regulation necessary for starting a game using credits when the MAXBET switch 6 is operated while the flow path switching solenoid 30 is energized. When the number of bets (3 in the present embodiment) is set, the flow path switching solenoid 30 is set to OFF and controlled to a non-energized state.

  In such a configuration, the slot machine 1 controls the flow path switching solenoid 30 constituting the switching means to be in an energized state, so that the player inserts a medal from the medal insertion unit 4 or the MAXBET switch 6 as a predetermined operation. In any of the operations, a predetermined number of bets necessary for starting a game can be set. In addition, when the prescribed number of bets necessary for the start of the game is set by a predetermined operation of the player while the flow path switching solenoid 30 is energized, the flow path switching solenoid 30 is controlled to be in a non-energized state. A situation where there is no need to insert a medal from the medal insertion unit 4 in order to start the game, and there is a high possibility that the player has a willingness to start a game, and a low possibility of further inserting a medal After that, the flow path switching solenoid 30 can be controlled to be in a non-energized state, and the time during which the flow path switching solenoid 30 is in the energized state is shortened to prevent deterioration of the flow path switching solenoid 30. Can do. Further, by shortening the time during which the flow path switching solenoid 30 is in the energized state, heat generation due to the energized state of the flow path switching solenoid 30 is reduced, and the influence of the heat generated on the members around the flow path switching solenoid 30 is affected. Can be reduced.

  In this embodiment, the main control unit 41 controls the flow path switching solenoid 30 to be in a non-energized state when the bet number is set by operating the MAXBET switch 6 as a predetermined operation of the player. Even if a specified number of bets (3 in this embodiment) necessary to start a game by a predetermined operation is set, or a bet number less than the specified number is set by a predetermined operation In this configuration, the flow path switching solenoid 30 is controlled to be in a non-energized state. However, the main control unit 41 operates at least when the MAXBET switch 6 is operated as a predetermined operation and a prescribed number of bets are set. Any configuration may be used as long as the path switching solenoid 30 is controlled to be in a non-energized state, and the flow path switching solenoid 30 is not controlled to be in a non-energized state when a bet number less than a prescribed number is set by a predetermined operation of the player. It may be configured to control so as to maintain the energized state.

  Further, in the present embodiment, as a predetermined operation of the player, when the bet number is set using credits by operating the MAXBET switch 6, the flow path switching solenoid 30 is controlled to be in a non-energized state. However, the predetermined operation may be a player's operation for setting a bet number using credits. For example, the bet number is set using credits by operating an operation means other than the MAXBET switch 6. In the slot machine that can be used, the operation of the operation means may be applied as the predetermined operation. For example, the slot machine can set the bet number using a credit by touching a predetermined member In this case, the predetermined operation may be touching the predetermined member, for example, by holding a part of the player's body over the predetermined member. In possible slot machine to set the bet number with the door, as the predetermined operation may be applied that holds the part of the body to the predetermined member.

  Further, in the present embodiment, the main control unit 41 sets the flow path switching solenoid 30 to OFF by effectively operating the start switch 7 in a state where the specified number of bets has been set, and the main control unit 41 does not operate. In a state in which one game is finished and a medal can be inserted, the medal is detected by the insertion port sensor 26, and the flow path switching solenoid 30 is set to ON to control the energized state. In other words, even if the medal can be inserted after the end of one game, the flow path switching solenoid 30 is controlled to be in a non-energized state until the medal is detected by the slot sensor 26. However, as shown in FIG. 16, when the main control unit 41 is in a state where a medal can be inserted after the end of one game, the flow control solenoid 30 is turned on when the one game is ended. Set to may be controlled energized. Even in such a configuration, as in the present embodiment, when the bet amount is set using credits by operating the MAXBET switch 6 as a predetermined operation of the player, the flow path switching solenoid 30 is not turned on. By adopting a configuration in which the energized state is controlled, the flow path switching solenoid 30 can be controlled to be in a non-energized state after it becomes unnecessary to insert a medal from the medal insertion unit 4 in order to start the game. This can shorten the time during which the flow path switching solenoid 30 is in the energized state.

  In the present embodiment, the main control unit 41 performs the betting number setting process when the operation of the MAXBET switch 6 is detected in the game start waiting process, and the betting number is set by the betting number setting process. In this case, the flow path switching solenoid 30 is set to OFF and controlled to be in a non-energized state, that is, the flow path switching solenoid 30 is controlled to be in a non-energized state after the betting number is set by the betting number setting process. However, the main control unit 41 may be configured to control the flow path switching solenoid 30 to a non-energized state when at least the MAXBET switch 6 is operated to set a bet amount using credits. In a situation where the bet amount can be set using credits by operating the MAXBET switch 6, the MAXBET switch 6 is operated. It is, it may be configured to set the betting amount after setting the flow channel switching solenoid 30 to OFF.

  In this embodiment, the main control unit 41 sets the flow path switching solenoid 30 to OFF after performing the betting number setting process when the operation of the MAXBET switch 6 is detected in the game start waiting process. As shown in FIG. 17A, the bet number is set by the bet number setting process, and the 1 to 3 BET LEDs 14 to 16 corresponding to the set bet number are turned on. After the setting, the flow path switching solenoid 30 is controlled to be in a non-energized state, but the main control unit 41 is operated by operating the MAXBET switch 6 as shown in FIG. 17B, for example. In a situation where the bet number can be set using credits, the MAXBET switch 6 is operated to set the bet number after setting the flow path switching solenoid 30 to OFF. The 1 to 3 BETLEDs 14 to 16 corresponding to the set bet number may be turned on.

  In the present embodiment, the main control unit 41 performs the betting number setting process when the operation of the MAXBET switch 6 is detected in the game start waiting process, and the betting number is set by the betting number setting process. In this case, after setting the 1 to 3 BETLEDs 14 to 16 corresponding to the set number of bets to be turned on, the flow path switching solenoid 30 is set to OFF and controlled to a non-energized state, that is, the set bet After setting to turn on all 1 to 3 BETLEDs 14 to 16 corresponding to the number, the flow path switching solenoid 30 is set to OFF, but the flow path switching solenoid 30 is set to OFF to be in a non-energized state. The timing to control is, for example, so that at least one of the 1 to 3 BET LEDs 14 to 16 corresponding to the set bet number is lit. It may be the timing before setting, or the timing before setting to turn on one LED among the 1 to 3 BETLEDs 14 to 16 corresponding to the set bet number, and may be the timing before setting to turn on the other LEDs. The timing before at least one 1 to 3 BETLEDs 14 to 16 corresponding to the set bet number may be turned on, or at least a part of 1 to 3 BETLEDs 14 to 16 corresponding to the set bet number is turned on. The subsequent timing may be used, or the timing after all the 1 to 3 BETLEDs 14 to 16 corresponding to the set bet number are turned on.

  In the game start waiting process, the main control unit 41 of the present embodiment has a predetermined number of bets (3 in the present embodiment) required for starting a game by the player operating the MAXBET switch 6 as a predetermined operation. When set, the flow path switching solenoid 30 is set to OFF and controlled to be in a non-energized state regardless of whether the flow path switching solenoid 30 is in a non-energized state or in an energized state. With such a configuration, the flow path switching solenoid 30 can be reliably controlled to be in a non-energized state after the possibility that a medal is further inserted from the medal insertion unit 4 is low.

  The slot machine 1 of the present embodiment includes an insertion port sensor 26 that detects a medal inserted from the medal payout opening 9 on the upstream side of the flow path switching plate 147, and the main control unit 41 can insert a medal. In a state where the specified number of bets has not been set or the credit has not reached the maximum value 50 in the period from the end of one game to the start of the next game. When a medal is detected by H.26, the flow path switching solenoid 30 is set to ON and controlled to be energized. In such a configuration, the main control unit 41 controls the flow path switching solenoid 30 to the non-energized state until a medal is detected by the insertion port sensor 26 even in a state where a medal can be inserted from the medal insertion unit 4. It is possible to reduce the time during which the flow path switching solenoid 30 is in the energized state and prevent the flow path switching solenoid 30 from deteriorating.

  In this embodiment, in the period from the end of one game to the start of the next game, when the prescribed number of bets is not set or the credit has not reached the maximum value 50, Regardless of whether or not a re-game is given, the medal can be inserted, but in the period from the end of one game to the start of the next game, the re-game is given If the specified number of bets has not been set or the credit has not reached the maximum value 50, the medal insertion may be disabled.

  In the present embodiment, the main control unit 41 sets the flow path switching solenoid 30 to ON and controls the energized state when a medal is detected by the slot sensor 26 in a state where the medal can be inserted. As shown in FIG. 18, when a medal is detected by the insertion slot sensor 26 in a state where the medal can be inserted, the medal detected by the insertion slot sensor 26 is detected after the medal is detected. Performs inflow passage passage time waiting control that waits for a predetermined time required to flow down the medal inflow passage 29a and reach the passage switching plate 147 (hereinafter, referred to as inflow passage passage time). It is good also as a structure which sets the flow-path switching solenoid 30 to ON after the passage of time, and controls to an energized state. With this configuration, after the medal is detected by the insertion port sensor 26, the flow path switching solenoid 30 can be controlled to be in a non-energized state for the inflow flow path passage time, and the flow path switching solenoid 30 is The time in the energized state can be further shortened. The inflow passage passage time is based on an actual measurement value of the time required for the medal to be detected by the insertion port sensor 26 and reaching the passage switching plate 147, the shape of the medal receiving passage 29b of the medal selector 29, and the like. The time obtained by subtracting the time required from the time at which at least the flow path switching solenoid 30 is set to ON until the flow path switching plate 147 actually moves to the receiving position from the time obtained by actual measurement or the like. It is preferable to set to.

  The slot machine 1 according to the present embodiment includes a start switch 7 that a player operates to start a game, and an insertion port that detects a medal inserted from the medal payout port 9 on the upstream side of the flow path switching plate 147. The main control unit 41 is in a state in which medals can be inserted (a state in which a prescribed number of bets has not been set in a period from the end of one game to the start of the next game). (In a state in which the credit has not reached the maximum value 50), the medal is detected by the insertion port sensor 26, and the flow path switching solenoid 30 is controlled to be in the energized state. When the specified number of bets (3 in this embodiment) is set by the operation of or when the start switch 7 is operated in a state where the specified number of bets is set , Is configured to control to set the flow channel switching solenoid 30 is turned OFF in the non-energized state. In such a configuration, the main control unit 41 controls the flow path switching solenoid 30 to be in an energized state by detecting the medal inserted from the medal insertion unit 4 by the insertion port sensor 26, and then plays the game by a predetermined operation. When a prescribed number of bets necessary for starting the game is set, or when the start switch 7 is operated, the flow path switching solenoid 30 is set to OFF and controlled to a non-energized state so that a medal can be obtained. The flow path switching solenoid over a period from when it is detected by the slot sensor 26 until when a predetermined number of bets necessary for starting the game is set by a predetermined operation or when the start switch 7 is operated. 30 is kept in the energized state, so that the flow path switching solenoid 30 is switched to the energized state every time a medal is detected by the slot sensor 26 during the period. It is not necessary to perform obtaining control, can reduce the control load of the channel switching solenoid 30 by the main control unit 41.

  The slot machine 1 according to this embodiment is inserted from a medal payout port 9 and a checkout switch 10 that is operated to return a medal that is set for the number of bets and a medal that is stored in the credit. And a sub-control unit 91 that controls the production, and the main control unit 41 determines that the checkout switch 10 is turned on by the player. Based on the operation, it is possible to perform a settlement process for returning all medals stored in the credit, and the sub-control unit 91 operates based on the operation of the settlement switch 10 by the player. For the period during which the settlement process is performed by the control unit 41, during the settlement, and for a predetermined period (in this example, 10 seconds) after the period during which the settlement process is performed. The main control unit 41 sets the flow path switching solenoid 30 in a non-energized state for a period during which the settlement process is performed and a predetermined period thereafter (10 seconds in this embodiment). By performing the control, the flow path switching solenoid 30 is controlled to be in a non-energized state during the period in which the sub-control unit 91 side performs the settlement in-progress notification and the settlement-related notification. Then, after the settlement-in-progress notification and the settlement-related notification are terminated, a medal is detected by the insertion port sensor 26, so that the flow path switching solenoid 30 is set to ON and controlled to be in an energized state. In such a configuration, the main control unit 41 is in a period during which the sub-control unit 91 side performs the settlement-in-progress notification and the settlement-related notification, and from the end of the notification until the insertion port sensor 26 detects a medal. In this period, the flow path switching solenoid 30 is controlled to be in a non-energized state, so that the time during which the flow path switching solenoid 30 is in the energized state is reduced during a period when the possibility that a medal is inserted from the medal insertion unit 4 is low. Can do.

  In the game start waiting process, the main control unit 41 according to the present embodiment detects the medal by the insertion port sensor 26 in a state where a medal can be inserted after the end of one game. Set to ON to control the energized state. Further, every time a medal is detected by the insertion port sensor 26, a predetermined value (for example, a value corresponding to 10 seconds) is set in the flow path switching control timer to start timing, and finally the insertion port sensor 26 is set. Then, control is performed so that it can be determined whether or not a predetermined time (for example, 10 seconds) has elapsed after the medal is detected. Then, the passage switching solenoid 30 is set to OFF by specifying that a predetermined time has passed after the medal is detected by the insertion port sensor 26 based on the passage switching control timer. It is the structure controlled to a non-energized state. In such a configuration, in a state where a medal can be inserted, the medal is inserted by a player or the like and detected by the insertion port sensor 26 to control the flow path switching solenoid 30 to the energized state. When the predetermined time elapses without being turned on, or when the predetermined time elapses without the operation of the MAXBET switch 6, the operation of the start switch 7, or the operation of the checkout switch 10, 30 can be controlled to be in a non-energized state, and the time during which the flow path switching solenoid 30 is in the energized state can be shortened. However, a medal is detected by the slot sensor 26 in a state where a medal can be inserted. Thus, after the flow path switching solenoid 30 is set to ON, the flow path switching solenoid 30 is not turned on when a predetermined time has elapsed. Without the control to the state, the player operates the MAXBET switch 6, the start switch 7, and the checkout switch 10 to set the flow path switching solenoid 30 to OFF and control it to a non-energized state. Even with this configuration, it is possible to sufficiently shorten the time during which the flow path switching solenoid 30 is energized.

  The slot machine 1 of this embodiment is inserted with a medal receiving flow path 29b for guiding inserted medals to the hopper tank 34a side, and a medal return flow path 29c for guiding the inserted medals to the medal payout exit 9 side. A flow path switching plate 147 for switching the flow path so that the medal is flowed into one of the medal receiving flow path 29b or the medal return flow path 29c, and a flow path switching solenoid constituting a switching means for operating the flow path switching plate 147 30 and inserted medal sensors 31a to 31c for detecting medals flowing down the medal receiving flow path 29b. In the medal receiving flow path 29b, the medal is positioned upstream of the detection range A of the inserted medal sensors 31a to 31c. The movable piece 180 of the insertion medal sensor 31b is arranged as a decelerating means for decelerating the flow speed of the medals. In such a configuration, the medal and the movable piece 180 are brought into contact with each other until the medal inserted from the medal insertion unit 4 reaches the detection range A, and a frictional force or the like is applied to the medal. Therefore, the medal inserted from the medal insertion unit 4 is allowed to pass through the detection range A of the inserted medal sensors 31a to 31c at a speed equal to or lower than a predetermined value, and the inserted medal sensors 31a to 31c are used. Medals can be detected accurately.

  The slot machine 1 of the present embodiment includes a medal receiving flow path 29b for guiding medals inserted from the medal insertion section 4 to the hopper tank 34a side, and a medal return flow path for guiding the inserted medals to the medal payout exit 9 side. 29c, a flow path switching plate 147 for switching the flow path so that the inserted medal flows into one of the medal receiving flow path 29b or the medal return flow path 29c, and a switching means for operating the flow path switching plate 147. A flow path switching solenoid 30 and insertion medal sensors 31a to 31c for detecting medals flowing down the medal receiving flow path 29b. In the medal receiving flow path 29b, the detection range A of the inserted medal sensors 31a to 31c is larger. The movable piece 180 of the insertion medal sensor 31b is arranged on the upstream side as a decelerating means for decelerating the flow speed of the medal, When the movable piece 180 of the incoming medal sensor 31b comes into contact with a medal flowing down from the medal insertion portion 4 side to the hopper tank 34a side, the movable piece 180 moves out of the medal receiving passage 29b and passes the medal to the hopper tank 34a side. On the other hand, when it comes into contact with a medal that flows backward from the hopper tank 34a side to the medal insertion unit 4 side, the medal is not operated and the medal insertion unit 4 side is limited by restricting the movement of the medal. It is the structure which regulates to move to. In such a configuration, even if the medal may flow backward to the medal insertion unit 4 in the passage where the medal inserted from the medal insertion unit 4 flows down, the movable piece of the insertion medal sensor 31b. Since the movement of medals is regulated by 180, it is possible to prevent the medals from being illegally moved to the medal insertion unit 4 side. Further, the movable piece 180 of the inserted medal sensor 31b can decelerate the flow speed of the medal and can restrict the movement of the medal toward the medal insertion unit 4 side. There is no need to use other means to regulate the movement to the 4 side, and the cost can be reduced.

  The slot machine 1 according to the present embodiment includes insertion medal sensors 31a to 31c that detect medals flowing down a medal receiving passage 29b that guides medals inserted from the medal insertion unit 4 to the hopper tank 34a side. The movable piece 180 of 31b can restrict the movement of the medals flowing backward from the hopper tank 34a side to the medal insertion unit 4 side, and the main control unit 41 performs the medal insertion signal process performed in the game start waiting process. The medal is detected by the inserted medal sensors 31a to 31c for a period longer than a predetermined period, so that it is determined that an abnormality related to the passage of the medal is detected, and error processing is performed. The movable piece 180 has a medal at a position where a backward medal is detected by the inserted medal sensor 31c. It is configured to be disposed to move to regulate. In such a configuration, the movable piece 180 of the inserted medal sensor 31b restricts movement of the medal to the medal insertion unit 4 at a position where the medal is detected by the inserted medal sensor 31c. When moved to the medal insertion unit 4 side, the movement of the medal can be restricted, and the medal can be detected by the insertion medal sensor 31c. Abnormality can be determined.

  In this embodiment, the movable piece 180 of the inserted medal sensor 31b is arranged so as to restrict the movement of the medal at the position where the backward medal is detected by the inserted medal sensor 31c. Any configuration may be used as long as it restricts the movement of the backward medal so that it is detected by at least one of the inserted medal sensors 31a to 31c used in the abnormality determination in the unit 41.

  Next, the state of the movable piece (first backflow prevention means) of the inserted medal sensor and the movable piece (second backflow prevention means) of the medal backflow prevention device in and out of the medal receiving flow path will be described with reference to FIG.

  As described above, the movable piece 180 (sometimes referred to as first backflow prevention means) of the insertion medal sensor 31b provided in the medal selector 29 causes the medal to flow from the medal insertion portion 4 through the medal receiving passage 29b. When flowing down toward the outlet 142, the medal is retracted from the medal receiving flow path 29b and does not protrude into the medal receiving flow path 29b. On the other hand, when the medal is not flowing down, the biasing member is attached. The state of projecting into the medal receiving passage 29b by the force is brought about. When a medal moves in the medal receiving flow path 29b from the outlet 142 in the direction of the medal insertion portion 4 and backflows, the movement of the medal is limited in a state of protruding into the medal receiving flow path 29b, It is designed to prevent backflow.

  As a result, as shown in FIG. 19, the movable piece 180 (first backflow prevention means) of the insertion medal sensor 31b causes an object such as a medal to flow in the medal receiving passage 29b from the medal insertion portion 4 toward the outlet 142. Thus, the transition of the detection state of the inserted medal sensors 31a to 31c is a normal transition (for example, after the ON state of the inserted medal sensor 31b which is a physical sensor is detected, the other inserted medal sensors 31a and 31c are in the ON state. Or the like so that the medal receiving flow path 29b does not protrude. When the medal does not flow down the medal receiving flow path 29b, the medal receiving flow path 29b is always used. It will be in a state of protruding inward.

Further, as described above, the movable piece 48b of the medal backflow prevention device 48 provided inside the medal selector 29 (sometimes referred to as second backflow prevention means), the backflow prevention solenoid 48a is in the OFF state (non-excitation state). If the backflow prevention solenoid 48a is controlled to be in the ON state (excited state), it does not protrude into the medal receiving flow path 29b. It is like that.
Accordingly, as shown in FIG. 19, the movable piece 48b (second backflow prevention means) of the medal backflow prevention device 48 allows the object such as a medal to pass through the medal receiving flow path 29b from the outflow port 142 toward the medal insertion portion 4. By moving and flowing backward, the transition of the detection state of the inserted medal sensors 31a to 31c is abnormal (for example, before the ON state of the inserted medal sensor 31b which is a physical sensor is detected, the other inserted medal sensors 31a). , 31c such that the ON state of 31c is detected, etc.), the backflow prevention solenoid 48a is controlled to be in the ON state, and is operated so as to protrude into the medal receiving flow path 29b. Become. And it is maintained in the position which protrudes in the medal | token receiving flow path 29b over the period when the backflow prevention solenoid 48a is controlled by the ON state. After that, the error condition release condition is satisfied, and the backflow prevention solenoid 48a is controlled to be in the OFF state, so that it does not protrude into the medal receiving flow path 29b.

  Further, the movable piece 48b (second backflow prevention means) of the medal backflow prevention device 48 is used when the time during which the detection states of the inserted medal sensors 31a to 31c are in the ON state is outside the predetermined time range described above, that is, a medal or the like. Even when an abnormality that may cause a reverse flow occurs, an object such as a medal flows backward to detect an abnormality in the detection state transition of the inserted medal sensors 31a to 31c. When the backflow prevention solenoid 48a is controlled to be in the ON state, the backflow prevention solenoid 48a is operated so as to protrude into the medal receiving passage 29b. And the cancellation | release condition of an error state is satisfied, and it will be in the state which does not protrude in the medal | token receiving flow path 29b because the backflow prevention solenoid 48a is controlled by the OFF state.

  Some conventional gaming machines have a configuration in which a backflow preventing member for preventing backflow of medals inserted from the outside is provided. In such a configuration, although the inserted medal or the like is prevented from being taken out from the medal slot by the backflow prevention member, it is possible to drop the thrown object into the return slot and take it out to the outside. For example, when a fraud that misdetects insertion of a medal using a medal with a thread attached (so-called thread hanging), it is possible to take out a member that has been used improperly from the return port. There is a risk that the traces made will not remain.
