  In general, a front door of a gaming machine is configured to be openable and closable around a hinge shaft disposed between a housing frame and the front door. The weight of the front door is determined by placing the sliding surface of the front door side hinge plate on the sliding surface of the case frame side hinge plate that projects horizontally from the front door housing frame side to the lower side of the front door. I support. Therefore, the sliding surface of the door side hinge plate and the sliding surface of the housing frame side hinge plate are relatively slid while the weight of the front door is applied.

  Therefore, when opening and closing the front door, wear powder is generated between the sliding surface of the door-side hinge plate and the sliding surface of the housing frame-side hinge plate. The wear powder is easily oxidized because it is in a fine powder form. On the other hand, wear powder due to friction is easily generated between the hinge shaft and the bearing hole that supports the hinge shaft.

  Therefore, since the electrical conduction state is hindered by oxidized wear powder or non-conductive wear powder, a stable electrical conduction state is maintained between the front door side hinge plate and the housing frame side hinge plate. It will be difficult to keep. Therefore, in the conventional one, a dedicated ground wire is connected between the front door side and the housing frame side to maintain electrical continuity between the front door side and the housing frame side. .

  When wiring this dedicated ground wire, it is necessary to prevent the opening and closing of the front door and the ground wire from interfering with each other, increasing the manufacturing cost of the gaming machine and increasing the product price. Was invited. Also, if a ground wire is wired between the front door side and the housing frame side, when removing or assembling the front door during maintenance, the ground wire is removed or attached at the same time. There was a problem that work efficiency deteriorated.

  The present invention has been made in view of the above-described problems, and is a game capable of obtaining electrical continuity between the front door side and the housing frame side without wiring a dedicated ground wire. The purpose is to provide a machine. Another object of the present invention is to facilitate maintenance accompanying the removal of the front door in the gaming machine by eliminating the wiring of the dedicated ground wire. Another object is to reduce the manufacturing cost and product price of gaming machines.

  The present invention includes a housing frame configured in a box shape with an open front surface, a front door arranged to be openable and closable so as to close the opening of the housing frame, and the front door with respect to the housing frame. A hinge shaft that is supported so as to be freely opened and closed, and a conductive housing frame side hinge plate that is provided on the housing frame and supports the weight of the front door, wherein the hinge shaft is at least a bottom surface of the front door. In the gaming machine provided between the housing frame side hinge plate, electrical conduction between the conductive door side hinge plate provided on the bottom surface of the front door and the housing frame side hinge plate. The door-side hinge plate or the housing provided with a contact conducting member that is secured to the door-side hinge plate or the housing frame-side hinge plate, and the contact conducting member is provided with the contact conducting member. It always abuts against the housing frame side hinge plate or the door side hinge plate facing the frame side hinge plate. A contact portion of the conductive, said by comprising a conductive elastic member which urges the abutting portion toward the housing frame hinge plate or the door-side hinge plate, and a most important feature.

  According to the present invention, the contact portion of the contact conducting member provided on the door side hinge plate or the housing frame side hinge plate always abuts on the housing frame side hinge plate or the door side hinge plate. The electroconductive elastic member which urges like this was provided. By interposing this conductive elastic member, it is possible to ensure an electrical conduction state between the door side hinge plate and the housing frame side hinge plate.

  In addition, according to the present invention, since the electrical continuity between the door side hinge plate and the housing frame side hinge plate can be ensured, the front wire is not required without wiring separately. It is possible to prevent the occurrence of a potential difference between the door side and the housing frame side.

  Further, as in the case where the opening and closing operation of the front door is frequently performed, wear powder is generated between the sliding surface of the door side hinge plate and the sliding surface of the housing frame side hinge plate, Further, even if the wear powder is oxidized or the wear powder is non-conductive wear powder, in the gaming machine according to the present invention, the door-side hinge plate and the housing frame side are separated by the contact conductive member. An electrical conduction state between the hinge plate and the hinge plate can be maintained.

  Furthermore, by using materials with excellent conductivity and wear resistance, such as phosphor bronze, beryllium copper, white, white copper, silicon copper, aluminum bronze, etc. as contact conductive members, contact conductive members and door side hinge plates, etc. In addition, it is possible to reduce poor conduction due to oxidized wear powder while suppressing the generation of wear powder due to sliding between them.

  Further, according to the present invention, the contact conducting member is disposed at a position away from the sliding surface of the door-side hinge plate and the sliding surface of the housing frame-side hinge plate where a large amount of wear powder is likely to be generated. Can be kept. Therefore, the electrical conduction between the front door side hinge plate and the housing frame side hinge plate is not disturbed by the abrasion powder generated on the sliding surface, and the electrical connection state by the contact conducting member is not hindered. It becomes possible to maintain the conduction state.

  Further, even when the medals are paid out, even if the medals or the medals and the medal tray are rubbed against each other and the front door is charged with static electricity, the static electricity charged on the front door is transmitted through the contact conducting member. It flows out to the body frame side hinge plate. For this reason, the player does not feel discomfort due to static electricity.

  Further, in the present invention, the front door side and the housing frame side can be used regardless of the position of the front door in the closed state, the front door opened state, or the intermediate state. The potential difference generated during the period can be removed through the contact conducting member. Therefore, the hall clerk or the like can be used when the power of the gaming machine is turned on or off, when the setting is changed, when the sound effect volume is set, or when the error is cleared when the game medium is jammed. Even when the door is opened and closed directly by hand, the front door is not charged with static electricity, so that a hall clerk or the like can open and close the front door with peace of mind.

  Further, according to the present invention, an electrically conductive state between the front door side and the housing frame side without wiring a ground wire between the front door side and the housing frame side. Can be obtained. Thereby, the manufacturing process of the gaming machine can be simplified, and the manufacturing cost and product price of the gaming machine can be reduced. Further, since the ground wire is not necessary, maintenance accompanied with removal of the front door is facilitated.

  Further, the contact conducting member urges a force in the direction of lifting the door side hinge plate, so that the sliding surface of the door side hinge plate and the sliding surface of the housing frame side hinge plate are in between. The applied load can be reduced, the frictional force when opening and closing the front door can be reduced, and the opening and closing operation of the front door can be performed smoothly.

  In the present invention, the contact conductive member slidably accommodates the abutting portion and includes an accommodating portion for accommodating the conductive elastic member, and the abutting portion protrudes from the accommodating portion with a small diameter. And a large-diameter engaging portion accommodated in the accommodating portion, and the accommodating portion includes an engaging opening that allows the protruding portion to protrude and engages the engaging portion. can do.

According to the present invention, since the housing portion slidably houses the contact portion of the contact conducting member, the contact portion is always directed toward the housing frame side hinge plate or the door side hinge plate. I can guide you. In addition, the housing portion is provided with a locking opening that allows the protruding portion to protrude and engages a large-diameter locking portion of the contact conducting member to prevent the contact conducting member from falling off. Thereby, dropping of the contact portion can be prevented.
As a result, the contact portion of the gaming machine is removed so that the contact portion can be slidably received while the contact portion of the contact conduction member prevents the contact conduction member from falling off. Becomes easier.

Further, in the present invention, the shape of the contact portion can be formed into a spherical shape. By forming the contact portion in a spherical shape, the contact portion can perform a rolling motion with respect to the door side hinge plate or the housing frame side hinge plate.
As described above, the contact portion of the contact conducting member performs a rolling motion with respect to the door-side hinge plate or the housing frame-side hinge plate, thereby reducing the frictional force when opening and closing the front door. The opening and closing of the front door can be lightened.

  In the present invention, a metal door-side ground plate is disposed on the inner peripheral edge of the front door, and the door-side hinge plate is fixed to the door-side ground plate in a state of ensuring electrical continuity, and the housing Adopting a structure in which a metal housing frame side grounding plate is arranged on the inner peripheral edge of the frame and the housing frame side hinge plate is fixed to the housing frame side grounding plate in a state of ensuring electrical continuity.

The “cherry small part”, “bell small part”, and “watermelon small part” described above may be simply referred to as “small part”.

  “Replay” is established by displaying “replay-replay-replay” as a combination of symbols along the valid line 8. When “Replay” is established, it is possible to enter the same gaming state as when the same number of medals are automatically inserted, and the player can play the next unit game without newly inserting medals. . That is, when “Replay” is established, it is possible to play a game again under the same conditions as the previous game without inputting the game value.

  By displaying “7-7-7” as a combination of symbols along the valid line 8, “BB” (so-called big bonus) is established. When “BB” is established, medals are not paid out, but in a predetermined number of unit games or a predetermined number of unit games performed until a predetermined number of game values are paid out, “RB” (so-called Regular bonuses) are more likely to be randomized.

  “RB-BAR-BAR” is displayed as a combination of symbols along the valid line 8 to establish “RB”. Even if “RB” is established, medals are not paid out, but “RB” is performed in a predetermined number of unit games thereafter.

  In addition, any of the above-mentioned small roles such as “cherry small portion”, “bell small portion”, “watermelon small portion”, and “replay”, or bonuses such as “BB” and “RB” When a symbol combination that does not correspond to the above is displayed, “losing” is established.

  As described above, the symbol combination table shown in FIG. 4 defines the symbol combinations related to winning, the display combination corresponding to the winning combination, and the number of payouts. When the symbol combination displayed on the display windows 3L, 3C, and 3R matches the symbol specified in the symbol combination table, the display combination and the number of payouts are determined according to the symbol combination. The If the symbol combination displayed on the display windows 3L, 3C, and 3R does not match the symbol combination defined in the symbol combination table, a non-winning “losing” is determined.

  Next, the gaming state will be described. The game state indicates a game state during a unit game or a unit game performed several times, and includes a basic “general game state” and an “RB game state” advantageous to the player.

  The “RB gaming state” is a gaming state in which a probability lottery table that is easy to win a display combination that can acquire medals is selected when internal lottery is performed, and it is advantageous for a player to easily acquire a gaming value. It is in a gaming state. The “probability lottery table” will be described later.

  In the establishment of “RB”, an end condition for ending the “RB gaming state” is defined. As an ending condition for the “RB gaming state”, a condition that a predetermined number of possible games (for example, 12 times) has been consumed, or a condition that a predetermined number of possible winnings (for example, 8 times) has been consumed. , And ends when one of the conditions is satisfied. The possible number of games is the number of unit games that can be played during the “RB” operation, and the possible number of winnings is the number of unit games that can be won during the “RB” operation.

  Next, a probability lottery table referred to in the internal lottery process of step 5 (hereinafter, abbreviated as “S”) in FIG. 8 to be described later will be described with reference to FIGS. The probability lottery table is provided for each gaming state such as the general gaming state and the “RB gaming state”, and is stored as a predetermined data table in a ROM 32 (see FIG. 7) described later. FIG. 5 shows a general gaming state probability lottery table, and FIG. 6 shows an RB gaming state probability lottery table.

  The random number range of these probability lottery tables is a number from 0 to 65535, and one random number value is extracted from this random number range in the process of S3 in FIG. The winning combination is determined depending on whether the winning combination belongs to the random number range. For example, when the extracted random number is 20000 in the general gaming state, referring to the general gaming state probability lottery table in FIG. 5, since this random number belongs to the replay random number range, the winning combination is replay.

  The probability that this replay is determined as a winning combination is 8980/65536, which is obtained by dividing 8980 random values belonging to the numbers in the replay random number range 11880 to 20859 by the total number 65536 of numerical values belonging to the random number range. . The process for determining the winning combination is the same for other game states and other winning combinations.

  Next, the main circuit configuration of the pachislot machine 1 shown in FIG. 7 will be described. FIG. 7 shows peripheral devices (actuators) electrically connected to the main control circuit 55 and control signals transmitted from the main control circuit 55 around the main control circuit 55 that controls game processing operations in the pachislot machine 1. The circuit configuration of the sub-control circuit 56 and the like controlled based on this is shown.

  The peripheral device, the sub control circuit 56 and the like are connected to the main control circuit 55 through the interface circuit 38. The sub control circuit 56 controls the liquid crystal display device 5, the LEDs 57, the lamps 58, and the like based on the control signal from the main control circuit 55, and the speakers 21L, 21R based on the instructions of the volume control unit 59. Controls the output volume.

  The main control circuit 55 has a configuration in which a microcomputer 30 disposed on a circuit board is a main component, and a circuit for random number sampling and a clock pulse generation circuit are added thereto. The microcomputer 30 includes a CPU 31 that performs a control operation according to a preset program, and a ROM 32 and a RAM 33 that are storage means.

  The CPU 31 includes a clock pulse generation circuit 34 and a frequency divider 35 that generate a reference clock pulse, a random number generator 36 that generates a random number to be extracted (sampled), and a random number generated by the random number generator 36. A sampling circuit 37 is connected.

  As a means for sampling the random number generated by the random number generator 36, a random number is generated in the microcomputer 30, that is, based on the operation program of the CPU 31, and the generated random number is sampled. It is also possible to configure to acquire a random value. In this case, the random number generator 36 and the sampling circuit 37 can be omitted, or the random number sampling operation can be left as a backup.

  In the ROM 32 of the microcomputer 30, various “probabilities” for performing internal lottery using a program for realizing the processing in the CPU 31 and a random number value obtained by random number sampling performed each time the start lever 6 is operated (start operation). Corresponding to the operation of the “lottery table”, “bonus operating table” in which various information setting values to be set when the bonus is established, the left stop button 7L, the middle stop button 7C, and the right stop button 7R. A “stop control table” for determining a stop mode of the left reel 3L, the middle reel 3C, and the right reel 3R, a control signal for performing various control commands to be transmitted to the sub control circuit 56, and the like are stored.

  Various information is stored in the RAM 33. For example, the extracted random number value, various flags (for example, “BB in-operation flag”, “RB in-operation flag”), the number of medal credits, game state information, and the like are stored. A control signal is output from the main control circuit 55 to the sub control circuit 56 by communication in one direction.

  As a main actuator whose operation is controlled by a control signal from the microcomputer 30, a hopper (for payout) that pays out a predetermined number of medals out of medals stored by a command from the hopper drive circuit 42 is used. 43 including the drive unit), left reel 3L, middle reel 3C, and stepping motors 40L, 40C, and 40R that rotationally drive the right reel 3R.

  A motor drive circuit 39 for driving and controlling the stepping motors 40L, 40C, and 40R and a hopper drive circuit 42 for driving and controlling the hopper 43 are connected to the output unit of the CPU 31 via the interface circuit 38. Each of these drive circuits receives a control signal such as a drive command output from the CPU 31 and controls the operation of each actuator. The motor drive circuit 39 can perform control to rotate the stepping motors 40L, 40C, and 40R at an arbitrary speed or to stop at any position.

The main input signal generating means for generating an input signal necessary for the microcomputer 30 to output a control command includes a reel stop signal circuit 46, a start switch 6S, a inserted medal sensor 50, a 1BET button 11, a BET button 12, There are a MAXBET button 13, a C / P switch 14, a reel position detection circuit 41, a payout completion signal circuit 45, and the like, which are also connected to the CPU 31 via the interface circuit 38.
The start switch 6S detects the operation of the start lever 6 and generates a start switch signal. The inserted medal sensor 50 detects a medal inserted into the medal slot 15.

  The CPU 31 can count the number of inserted medals after the inserted medal sensor 50 detects the insertion of medals, and can store a maximum of 50 medals as credits in the RAM 33. Further, the CPU 31 subtracts the medals credited to the RAM 33 according to the number of medals inserted into the medal slot 15 by the number corresponding to the operation of the 1BET button 11, the 2BET button 12, and the MAXBET button 13, The valid line 8 can be activated and the BET lamps 9a, 9b, 9c can be turned on.

  The reel stop signal circuit 46 stops the corresponding left reel 3L, middle reel 3C, and right reel 3R according to the operation of each left stop button 7L, middle stop button 7C, and right stop button 7R. Generate a signal. The reel position detection circuit 41 receives a reset pulse from the reel position detection circuit 41 that detects the reference positions of the left reel 3L, the middle reel 3C, and the right reel 3R, and receives the left reel 3L, the middle reel 3C, and the right reel. A signal for specifying the position of the symbol on the reel 3R is supplied to the CPU 31.

  That is, the CPU 31 inputs the reset pulse output from the reel position detection circuit 41, and then counts the number of drive pulses supplied to each of the stepping motors 40L, 40C, 40R, whereby the left reel 3L, the middle reel 3C. And the position of the symbol on the right reel 3R can be specified. The payout completion signal circuit 45 generates a signal for detecting completion of the medal payout when the count value of the medal detection unit 44 (the number of medals paid out from the hopper 43) reaches the designated number data value. .

  The random number generator 36 generates random values belonging to a certain numerical range (0 to 65535), and the sampling circuit 37 samples one random value at an appropriate timing after the start lever 6 is operated. An internal winning combination is determined based on the sampled random number, a probability lottery table stored in the ROM 32, and a conventionally known internal winning combination determination table (not shown).

  After the rotation of the left reel 3L, the middle reel 3C, and the right reel 3R is started, the number of drive pulses supplied to each of the stepping motors 40L, 40C, 40R is counted, and the counted value is a predetermined area of the RAM 33. Is written to. The photo interrupter 743 (see FIG. 4) obtains a reset pulse every time the left reel 3L, the middle reel 3C, and the right reel 3R make one rotation, and the reset pulse is input to the CPU 31 via the reel position detection circuit 41. Is done.

  Each time the reset pulse thus obtained is input, the count value of the drive pulse counted in the RAM 33 is cleared to “0”. Thus, in the RAM 33, the rotation positions of the left reel 3L, the middle reel 3C, and the right reel 3R are within the range in which the left reel 3L, the middle reel 3C, and the right reel 3R rotate once. The corresponding count value is stored.

  The ROM 32 stores the symbol combination table shown in FIG. The symbol combination table is referred to when a display combination is confirmed after all the left reel 3L, middle reel 3C, and right reel 3R are stopped, or when a winning combination is established and medals are paid out.

  In accordance with the internal lottery process performed based on the sampled random number value described above, the CPU 31 starts from the reel stop signal circuit 46 at the timing when the player operates the left stop button 7L, the middle stop button 7C, and the right stop button 7R, respectively. Based on the output reel stop signal and the number of sliding symbols determined based on the winning combination, a signal for controlling stop of the left reel 3L, middle reel 3C and right reel 3R is output to the motor drive circuit 39. .

  If the symbol stopped on the active line 8 after the internal winning is in a stop mode indicating winning, the CPU 31 updates the credit counter set in the RAM 33 according to the mode set by the C / P switch 14. . Alternatively, a payout command signal is output to the hopper drive circuit 42 to pay out a predetermined number of medals from the hopper 43.

  At this time, the medal detection unit 44 counts the number of medals to be paid out from the hopper 43, and when the counted number reaches a specified number, a medal payout completion signal is input from the payout completion signal circuit 45 to the CPU 31. The As a result, the CPU 31 stops driving the hopper 43 via the hopper drive circuit 42 and ends the “medal payout process”.

  The sub control circuit 56 controls the display of the liquid crystal display device 5 based on the control signal from the main control circuit 55, the LEDs 57 (the payout display unit 18, the credit display unit 19, the bonus game information display unit 20) and the lamps 58. Lighting control of (BET lamps 9a, 9b, 9c, decorative lamp 24) and sound output control from the speakers 21L, 21R are performed. The sub-control circuit 56 adjusts the sound from the speakers 21L and 21R based on the detection of the operation of the volume control unit 59.

  The sub control circuit 56 is configured on a circuit board different from the circuit board constituting the main control circuit 55, and includes a sound / lamp control circuit and an image control circuit (not shown). Based on the control signal transmitted from the main control circuit 55, the sound / lamp control circuit and the image control circuit can perform various kinds of determination and output of effect data (including image information, light emission pattern information, and sound information). Process.

  Next, the control process by the main control circuit 55 of the pachislo machine 1 will be described based on the flowchart of the main process shown in FIG. This flowchart shows a processing procedure executed by the control program stored in the ROM 32 and is executed by the CPU 31.

  In Sl, first, the CPU 31 performs an initialization process at the start of the game and an initialization process for the designated storage area in accordance with the set game state flag. When the initialization process at the start of the game is performed in S1, the storage contents stored in the RAM 33 are initialized, the communication port is initialized, the communication data is initialized, and the like.

  When the unit game is finished, the initialization process for the end of the unit game, that is, the information in the predetermined storage area of the RAM 33 at the end of the unit game is deleted. Specifically, erasing of data in the writable area of the RAM 33 used for the previous unit game, writing of parameters necessary for the next unit game to the write area of the RAM 33, starting of the sequence program for the next unit game Specify the address.

  Next, in S2, a medal insertion and start check process is performed. Specifically, for example, based on a replay operating flag, it is determined whether or not a replay has been established in the previous unit game, and if the replay has been established, a bet is placed in the previous unit game. The counter value of the inserted number set in the RAM 33 is updated according to the number of medals. On the other hand, when the replay is not established, the RAM 33 receives the input signal from the inserted medal sensor 50 that detects the number of medals inserted into the medal slot 15 or the input signal from the BET buttons 11, 12, and 13. The counter value of the set number of inserted sheets is updated.

  Further, the lighting of the BET lamps 9a, 9b, 9c is controlled and the number of effective lines is set according to the counter value of the inserted number. For example, if the counter value of the inserted number is 3, the display combination described later is determined based on the combination of symbols displayed on all the effective lines 8.

  In addition, a medal for playing a unit game is inserted (for example, the counter value of the inserted number is 1 or more, or the counter value of the inserted number is 3 which is the maximum value) The presence / absence of an input signal from the start switch 6S based on the operation of the start lever 6 is checked on the condition that 4.1 seconds have elapsed since the start of the unit game.

  In next S <b> 3, the CPU 31 performs a process of extracting a random value used for internal lottery. In this random number extraction process, one random number value is extracted from the random number value in the range of “0 to 65535” generated by the random number generator 36 via the sampling circuit 37, and the extracted random number value is obtained. It is stored in the random value storage area of the RAM 33. The random number extracted in the process of S3 is used in an internal lottery process (S5) described later.

  In the next S4, the CPU 31 refers to whether the “RB in-operation flag” is in the “on” state, the “BB in-operation flag” is in the “on” state, or the like, and the currently set gaming state Process to monitor.

  In the next S5, the CPU 31 selects a probability lottery table corresponding to the gaming state from the probability lottery tables shown in FIGS. 5 to 6 based on the gaming state information acquired in the processing of S4. An internal lottery process is performed based on the random number value extracted in the process of S3.

  This internal lottery process determines the internal winning combination by determining to which random value range the extracted random value belongs. Next, the CPU 31 transmits information on the internal winning combination and game state for displaying the game state and outputting the sound to the sub-control circuit 56, and notifies the player as necessary.

  In the next process of S6, the CPU 31 determines whether the player has operated any of the left stop button 7L, the middle stop button 7C, or the right stop button 7R, and the value of the unit game monitoring timer is 0. Monitor whether or not

  If it is determined that one of the left stop button 7L, middle stop button 7C, or right stop button 7R has been operated, the CPU 31 slides the reel on which the symbol is drawn based on the information of the internal winning combination. The number of symbols is determined to determine the stop position, the reel corresponding to the stop switch that has been stopped is decelerated, and stopped at a predetermined stop position.

  Next, in the process of S7, the CPU 31 determines whether or not all the reels are stopped. When it is determined that all the reels are stopped, all the left reels 3L, the middle reels 3C, and the right reels are determined. A combination of symbols displayed on the effective line 8 is obtained from the information regarding the stop position of 3R. By comparing the combination of symbols displayed on the effective line 8 with the symbol combination table shown in FIG. 4, the winning combination of the small role and the number of payouts are determined, the replay is established, the bonus is established, or the loss is determined. At the same time, information such as the number of unit games digested is stored in a predetermined storage area of the RAM 33.

  In the next S8, a medal payout process is performed based on the payout number set in S7. In this medal payout process, when the credit mode is selected by the C / P switch 14, the value of the credit counter set in the RAM 33 is updated based on the payout number information. By transmitting this updated information to the sub-control circuit 56, the value of the credit counter displayed on the credit display unit 19 is updated.

  When the payout mode is selected by the C / P switch 14, the hopper 43 is driven and controlled by the hopper drive circuit 42 based on the payout number information to pay out medals to the medal tray 17 (see FIG. 1). .

  When the medal is paid out, the CPU 31 updates the number of acquired medals. Thereafter, the CPU 31 transmits a payout end control signal to the sub-control circuit 56. This payout end control signal includes information indicating that the medal payout has been completed.

  In the next S9, using the current gaming state, processing is branched to a processing routine corresponding to the gaming state. For example, when the “RB in-operation flag” is “off”, or the “BB in-operation flag” is “off” and the current gaming state is neither “BB” nor “RB”. In step S10, processing proceeds to step S10. Further, when the “RB in-operation flag” is “ON”, or the “BB in-operation flag” is “ON” and the current gaming state is “BB” or “RB”, the processing of S11 is performed. Process to branch to.

  In S10, the CPU 31 determines whether or not the conditions for shifting to the “BB” or “RB” gaming state are complete based on the display combination determined in S7 and the number of payouts. If the condition for transitioning to the gaming state of “RB” is satisfied, the “RB in-operation flag” is set to “on” and the game possible number counter is set to “12”, and a winning is possible Set “8” in the number counter.

  If the condition for transition to the “BB gaming state” is satisfied, a process of setting the “BB operating flag” to “ON” is performed, and a value of “350” is set to the bonus end number counter. . If the condition for shifting to any gaming state is not satisfied, the gaming state flag is not changed.

  On the other hand, in S11, the CPU 31 determines whether or not to end the gaming state of “BB” or “RB” based on the display combination determined in S7, the number of payouts, and the currently set gaming state. Judgment is performed, and processing for ending the gaming state of “BB” or “RB” is performed.

  For example, if the current game state is “RB” and the game state is “RB” and there are 8 winnings, or if 12 unit games are consumed, When the “RB” end condition is satisfied, a process of setting the “RB in-operation flag” to “off” is performed. At the same time, a process of clearing the game possible number counter and the winning possible number counter is performed.

  Also, for example, when the current gaming state is “BB” and the gaming state of “BB” is consumed three times, when 30 unit games are consumed, or 350 or more medals have been paid out. If any one of the “BB” termination conditions is satisfied as in the case of the above, the “BB in-operation flag” is set to “off”. At the same time, a process of clearing the bonus end number counter is performed. If none of the game states satisfy the end condition, the game state flag is not changed, and the process returns to S1.

  Next, a state in which the front door 100 of the pachislot machine 1 is opened and the back surface of the front door 100 and the inside of the housing frame 2 are made visible will be described with reference to FIG.

  As shown in FIG. 9, the main control circuit 55, the left reel 3 </ b> L, the middle reel 3 </ b> C, the right reel 3 </ b> R, the hopper 43, and the like are accommodated in the housing frame 2 that forms the rear side of the pachislot machine 1. ing. The front door 100 constituting the front surface of the pachislot machine 1 is supported so as to be openable and closable via an upper hinge portion 110 and a lower hinge portion 120 provided between the front frame 100 and the housing frame 2. Since the front door 100 is configured to be openable and closable with respect to the housing frame 2, hall personnel can turn on and off the pachislot machine 1, change settings, and set sound effects. It is possible to open the front door 100 by hand when canceling an error such as when a medal is jammed or during other work.

  Further, as shown in FIG. 9, a control circuit based on a fraudulent act performed by inserting a wire or the like into the gap between the front door 100 and the housing frame 2 during the game on the inner peripheral edge of the opening in the housing frame 2. An overhang for preventing malfunction of 55 is formed. The projecting portion is formed of a metal frame side ground plate 2LP, 2RP, 2UP, 2DP. These casing frame side grounding plates 2LP, 2RP, 2UP, and 2DP are secured to each other with a screw through a wiring (not shown) while securing electrical continuity by fastening with screws.

  On the other hand, metal door side grounding plates 100LP, 100RP, 100UP, and a medal tray bottom plate 100DP are arranged on the inner peripheral edge of the back surface of the front door 100. The door-side ground plates 100LP, 100RP, 100UP, and the medal tray bottom plate 100DP are secured to each other by being screwed together. Furthermore, the door side ground plates 100LP, 100RP, 100UP and the medal tray bottom plate 100DP are electrically connected to the housing frame side ground plate 2LP of the housing frame 2 through the conductive lower hinge 120. ing. The medal tray bottom plate 100DP is a metal bottom plate disposed at the bottom of the medal tray 17 shown in FIG. 1 and can secure electrical continuity with medals stored in the medal tray 17. It is.

  Moreover, the upper hinge part 110 of the pachi-slot machine 1 shown in FIG. 9 includes an attachment / detachment mechanism for attaching / detaching the hinge shaft. One lower hinge portion 120 includes a mechanism for fitting and removing the hinge shaft, and a contact conducting member that enables electrical conduction between the front door 100 and the housing frame 2.

  The structure of the upper hinge part 110 is demonstrated using FIG. Moreover, the structure of the lower hinge part 120 is demonstrated using FIGS. 11-13.

FIG. 10 is a top view of the upper hinge part 110 provided with an attachment / detachment mechanism for attaching / detaching the hinge shaft in a rotatable manner, and is a cross-sectional view taken along the line XX shown in FIG.
As shown in FIG. 10, the housing frame side hinge plate 111 spot welded to the housing frame side grounding plate 2LP fixed to the housing frame 2 side is provided on the housing frame 2 side of the upper hinge portion 110. And a hinge shaft 112 that supports the front door 100 so as to be opened and closed.

  Further, on the front door 100 side of the upper hinge portion 110, a hinge base plate 114 spot-welded to a door-side ground plate 100RP having a U-shaped cross section fixed to the front door 100 side, and a hinge base plate 114 And a door side hinge plate 116 having a support groove 115 for receiving and supporting the hinge shaft 112 in the back portion. The door side hinge plate 116 has a lock lever 117 that allows the hinge shaft 112 to be removed along the support groove 115 by releasing the restriction while positioning the hinge shaft 112 behind the support groove 115. And a pivot shaft 118 that pivotally supports the lock lever 117.

  Between the door side hinge plate 116 and the lock lever 117, by urging the force in the direction in which both parts are pulled together, the lock lever 117 is urged in the clockwise direction shown in FIG. A tension spring 119 is provided to prevent the hinge shaft 112 from falling off the support groove 115 in a normal use state.

  When an operator such as a hall attendant or a pachislot machine 1 maintenance operator performs the operation of removing the front door 100, the operator first rotates the lock lever 117 counterclockwise to lock the hinge shaft 112. Is released. Then, the operator can move the front door 100 in the lower left direction in FIG. 10 to move the hinge shaft 112 in the F direction of the support groove 115 and remove the hinge shaft 112 from the support groove 115.

  Next, the structure of the lower hinge part 120 is demonstrated using FIGS. 11-14. 11 is a cross-sectional view taken along the line XI shown in FIG. 9, and FIG. 12 is a cross-sectional view taken along the line XII shown in FIGS. 9 and 11. FIG. 13 is a cross-sectional view taken along arrow XIII shown in FIG. 11, and is a cross-sectional view taken along the hinge shaft portion of the lower hinge portion 120. FIG. 14 is a perspective view in which only the door side hinge plate, the housing frame side hinge plate, the hinge shaft, and the contact conducting member are taken out from the pachislot machine 1 and observed from an oblique direction for easy understanding.

  As shown in FIGS. 11 to 13, on the housing frame 2 side of the lower hinge portion 120, a metal housing frame side hinge plate 121 spot welded to the housing frame side grounding plate 2 LP and the front door And a hinge shaft 122 that supports 100 to be freely opened and closed. The hinge shaft 122 is fixed by welding to the housing frame side hinge plate 121. The housing frame side hinge plate 121 and the housing frame side ground plate 2LP are electrically connected to each other, and the case frame side ground plate 2DP is connected to the housing frame side ground plate 2DP using screws B (see FIGS. 12 and 13). By fastening together, electrical conduction is achieved among the housing frame side hinge plate 121, the housing frame side ground plate 2LP, and the housing frame side ground plate 2DP.

  In addition, on the front door 100 side of the lower hinge portion 120, a metal door-side hinge plate 126 fixed to the door-side ground plate 100RP having a U-shaped cross section fixed to the inside of the front door 100 by spot welding. It has. The door-side hinge plate 126 has a support hole 125 (see FIGS. 13 and 14) that supports the hinge shaft 122 and allows the hinge shaft 122 to be fitted and removed.

  By configuring the lower hinge portion 120 in this manner, the front door 100 can be rotated around the hinge shaft 122 to open and close the front door 100. When the front door 100 is closed, a housing groove 100G (see FIG. 5) in which an overhanging portion of the housing frame side grounding plate 2DP fixed to the lower inner periphery of the housing frame 2 is formed in the front door 100. 11 and FIG. 12). Accordingly, it is possible to prevent an illegal act performed by inserting a wire or the like into the gap between the front door 100 and the housing frame 2.

  In addition, a sliding surface 121C (see FIGS. 12 to 14) orthogonal to the hinge shaft 122 is formed around the hinge shaft 122 of the housing frame side hinge plate 121 so as to protrude. By bringing the sliding surface 121C into contact with the periphery of the support hole 125 of the door-side hinge plate 126 facing each other, the weight of the front door 100 can be supported. Initially, electrical continuity can be obtained between the housing frame side hinge plate 121 and the door side hinge plate 126 via the sliding surface 121C of the housing frame side hinge plate 121.

  However, as the front door 100 is repeatedly opened and closed, wear powder is generated between the sliding surface 121C and the door-side hinge plate 126, and the wear powder is interposed between the case frame-side hinge plate 121 and the door. The contact resistance with the side hinge plate 126 increases. Therefore, conventionally, a separate ground wire is connected between the housing frame side grounding plate 2LP on the housing frame 2 side and the door side grounding plate 100RP on the front door 100 side, so that the housing frame on the housing frame 2 side is provided. Electrical conduction was achieved between the side ground plates 2LP, 2RP, 2UP, and 2DP and the door side ground plates 100LP, 100RP, 100UP on the front door 100 side and the medal tray bottom plate 100DP.

  However, if a dedicated ground wire is separately wired between the front door and the housing frame, the manufacturing cost of the pachislot machine 1 is increased and the product price is increased. Also, during maintenance involving removal of the front door 100, it is necessary to remove and reconnect the ground wire, resulting in a problem that work efficiency deteriorates.

  Therefore, in the present invention, the contact conductive member 130 is separately arranged at a position different from the sliding surface 121C, and the contact portion 132 (see FIGS. 13 and 14) of the contact conductive member 130 is used as the door-side hinge plate 126. By energizing it toward the door, an electrical conduction state between the door side hinge plate 126 having conductivity and the casing frame side hinge plate 121 having conductivity is ensured. The contact conducting member 130 is fixed while ensuring conductivity by press-fitting or screwing into the housing frame side hinge plate 121.

  Next, the structure of the contact conduction member 130 will be described with reference to FIG. As shown in FIG. 13, the contact conducting member 130 includes an accommodation portion 133 that accommodates the contact portion 132 while slidably guiding the contact portion 132. The abutting portion 132 includes a small-diameter protruding portion 134 that protrudes from the accommodating portion 133 and a large-diameter locking portion 135 that is accommodated in the accommodating portion 133 and is slidably guided through the abutting portion 132. . An upper portion of the accommodating portion 133 is provided with a locking opening 136 that allows the protruding portion 134 to protrude and engages with the locking portion 135.

  In addition, the accommodating portion 133 is disposed between the locking portion 135 and the bottom surface of the accommodating portion 133 to urge the abutting portion 132 toward the door-side hinge plate 126 and to accommodate the abutting portion 132 and the accommodating portion 133. A conductive elastic member 137 that ensures electrical continuity with the bottom surface of the portion 133 is provided. The contact portion 132 and the conductive elastic member 137 may be made of a material having excellent conductivity such as phosphor bronze, beryllium copper, white, white copper, silicon copper, or aluminum bronze in order to ensure high conductivity. In addition, the surface of the contact portion 132 and the conductive elastic member 137 can be plated with gold, silver, copper, rhodium, or the like having excellent conductivity.
