Description

  The present invention relates to a gaming machine such as a pachinko machine.

  Conventionally, a locking device for locking an inner frame to an outer frame is incorporated in a gaming machine such as a pachinko machine. The locking device includes, for example, a cylinder lock that is inserted and rotated by inserting a key, two hook members that are pivotally supported and can be locked to a locked portion, and a lock that is associated with the operation of the key. It is well known to have a connecting rod that transmits the rotation of the shaft to the flange member.

  By the way, in the pachinko hall sima, a large number of pachinko machines are arranged side by side, and ball lending machines are arranged between adjacent pachinko machines. Due to the installation of this ball lending machine, adjacent pachinko machines are arranged at a slightly wider interval than the width of the ball lending machine, and a slight gap is generated between the pachinko machine and the ball lending machine. For this reason, it is possible to insert a wire such as a wire through the gap and apply a force directly to the flange member, particularly the lower flange member. When one of the hook members is tilted in this way (for example, the lower side), the movement is transmitted to the other (upper) hook member via the connecting rod, and as a result, the upper and lower hook members are tilted in conjunction with each other. Then, there is a risk of detachment from the locked portion. That is, there is a risk that a locking device that would otherwise be unlocked without using a dedicated key could be unlocked without using that key.

  Therefore, a locking device that can suppress such unauthorized unlocking has been proposed. The locking device includes a pair of hook members on the upper and lower sides, and the other hook member that is not unlocked in response to an unauthorized unlocking operation performed on one of the hook members. It is provided with a transmission cutoff mechanism that cuts off the transmission. That is, even if one hook member is tilted by a wire such as a wire, the transmission is cut off by the transmission blocking mechanism so that the other hook member is not interlocked.

  At the time of filing this application, the applicant knows the following as a document describing the above prior art.

JP2002-301251

However, even a pachinko machine equipped with the above-described transmission blocking mechanism may be unlocked if an unauthorized unlocking operation is simultaneously performed on a pair of upper and lower saddle members. That is, although transmission from one heel member to the other heel member is blocked by the transmission blocking mechanism, if both heel members are tilted together by an unauthorized unlocking operation, both heel members are separated from the locked portions. There was a risk of withdrawal. For this reason, in the above-described locking device, unauthorized unlocking cannot be reliably prevented, and anxiety about unauthorized unlocking remains.
Accordingly, an object of the present invention is to provide a gaming machine capable of reliably preventing unauthorized unlocking by a wire rod or the like.

  Effective means for solving the above problems will be described below. In addition, the effect | action etc. are demonstrated as needed.

  Means 1: a predetermined base member, an opening / closing member supported to be openable / closable with respect to the base member, and a lock provided on either the opening / closing member or the base member and unlocked by a key And at least one hook member that is provided on one of the opening / closing member and the base member and that is engaged with and released from the locked portion provided on the other, and the key according to the unlocking operation of the key. The transmission mechanism that transmits the operation of the lock to the collar member and disengages it from the locked portion, and the collar member disengages with respect to the direct unlocking operation to the collar member that is performed without using the key. And a locking mechanism that prohibits displacement to the side.

  Here, the “opening / closing member” may be any member that can be opened and closed with respect to the base member. For example, when the outer frame is a base member, the inner frame supported by the outer frame is referred to as the opening / closing member. In the case where the inner frame is used as a base member, the front frame supported by the inner frame can be used as the opening / closing member.

  According to the structure of the means 1, at the time of locking, the hook member is locked to the locked portion, and the opening / closing member is kept closed. When the key is unlocked, the lock operates according to the operation. The operation of the lock is transmitted to the eaves member through the transmission mechanism, the eaves member is detached from the locked portion, and the opening / closing member can be opened. On the other hand, when a direct unlocking operation (that is, an unauthorized unlocking operation) is performed on the scissors member with a wire or the like without using a key, the scissors member may be displaced to the detachment side by the lock mechanism. It is forbidden. As a result, the collar member continues to maintain the state of being locked to the locked portion and prevents the opening / closing member from opening. Therefore, it is possible to reliably prevent unauthorized unlocking by a wire or the like.

  Means 2: a predetermined base member, an opening / closing member supported so as to be openable / closable with respect to the base member, and a lock provided on either the opening / closing member or the base member and unlocked by a key A first hook member and a second hook member that are provided on either the opening / closing member or the base member, and are respectively locked and detached from two locked portions provided on the other; and A transmission mechanism that transmits the movement of the lock according to the unlocking operation of the key to the first and second hook members and disengages from the locked portion; and the operation that is performed without using the key. A first locking mechanism that prohibits the first hook member from displacing to the disengagement side with respect to a direct unlocking operation to the first hook member; and the second lock mechanism that is performed without using the key. For direct unlocking operation on the heel member, the second heel member is on the detachment side. Game machine characterized by comprising a second locking mechanism which prohibits the displacement.

  According to the structure of the means 2, at the time of locking, the first hook member and the second hook member are locked to the locked portion, and the opening / closing member is kept closed. When the key is unlocked, the lock operates according to the operation. The operation of the lock is transmitted to the first hook member and the second hook member through the transmission mechanism, respectively, and these hook members are detached from the locked portions, so that the opening / closing member can be opened. On the other hand, when a direct unlocking operation (unauthorized unlocking operation) is performed on the first hook member with a wire or the like without using a key, the first lock mechanism causes the first hook member to Displacement to the departure side is prohibited. In addition, when a direct unlocking operation (unauthorized unlocking operation) is performed on the second hook member, the second lock mechanism prohibits the second hook member from being displaced to the detachment side. The As a result, the first hook member and the second hook member continue to maintain the state of being locked to the locked portion, and prevent the opening / closing member from opening. Therefore, it is possible to reliably prevent unauthorized unlocking by a wire or the like.

  Means 3: In addition to the structure of Means 2, the first lock mechanism and the second lock mechanism are composed of a single lock mechanism that prohibits displacement of the first hook member and the second hook member. A gaming machine characterized by

  According to the configuration of the means 3, the displacement of the two flange members is prevented by one locking mechanism. In other words, the unauthorized unlocking operation for the first collar member and the unauthorized unlocking operation for the second collar member are prevented by the same locking mechanism. For this reason, it becomes possible to comprise a locking device with few parts, and a locking device can be reduced in size.

  Means 4: In addition to any one of the structures from means 1 to means 3, the flange member is supported so as to be tiltable by a shaft, and is locked and detached from the locked portion by the tilting. The transmission mechanism is connected to the collar member so as to be able to transmit power, and includes a coupling collar that moves in an unlocking direction in accordance with an unlocking operation of the key, and the locking mechanism is performed without using a key. A game machine comprising a movement blocking means for blocking the connection rod from moving in the unlocking direction with respect to a direct unlocking operation to the rod member. In addition, the number of eaves members may be one or more.

  Here, the position where the connecting rod is connected to the hook member (having the hooking claw portion at the tip) is not particularly limited, and may be, for example, between the hooking claw portion and the shaft. The position on the opposite side of the latching claw portion with respect to the shaft may be used. In the former case, the unlocking direction of the hook member and the unlocking direction of the connecting hook are the same direction. In the latter case, the unlocking direction of the hook member is opposite to the unlocking direction of the connecting hook. It becomes the direction.

  According to the configuration of the means 4, when the key is unlocked, the connecting rod moves in the unlocking direction, and the movement is transmitted to the rod member. Then, the collar member tilts and is detached from the locked portion. On the other hand, when an unauthorized unlocking operation is performed on the scissors member with a wire rod or the like without using a key, the movement restraining means prevents the connecting scissors from moving in the unlocking direction, thereby Continues to be locked to the locked portion. In this way, since the displacement of the flange member is prevented by preventing the movement of the connecting rod, unauthorized unlocking can be prevented without providing a complicated mechanism such as a transmission blocking mechanism.

  Means 5: In addition to the constitution of means 4, the movement preventing means has a contact position that restricts movement by contact and a non-contact position that does not restrict movement of the connection rod moving in the unlocking direction. And an elastic member that urges the contact piece toward the contact position, and resists the elastic force of the elastic member according to the unlocking operation of the key. The game machine further comprises a lock release portion that displaces the contact piece from the contact position to the non-contact position side.

  According to the configuration of the means 5, when the connecting rod tries to move in the unlocking direction by unauthorized unlocking to the flange member, the contact is brought into contact with the contact piece and the movement is prevented. In particular, since the contact piece is always urged toward the contact position, the movement of the connecting rod can be reliably prevented. On the other hand, the abutting piece is biased toward the abutting position by the elastic member. However, when an appropriate key unlocking operation is performed, the abutting piece is displaced to the non-abutting position by the unlocking portion. That is, by displacing the contact piece against the elastic force of the elastic member, the locked state is released and the connecting rod can be moved in the unlocking direction.

  Means 6: In addition to the structure of means 5, the abutment piece is disposed at a position where it can be directly operated when the opening / closing member is opened, and from the contact position to the non-contact position side by the operation. A game machine characterized in that it is supported so as to be displaceable.

  By the way, according to the configuration of the means 1 to the means 5, for example, when the opening / closing member is opened and the adjustment operation inside the gaming machine is performed, if the connecting rod returns to the locking direction for some reason, the locking mechanism is activated. The member cannot be tilted. In this case, in a gaming machine that does not include means for releasing the lock mechanism, the opening / closing member cannot be closed unless an appropriate unlocking operation is performed again using the key. In addition, in an assembly factory for gaming machines, an operation of attaching an opening / closing member (for example, an inner frame) to which a locking device is attached to a base member (for example, an outer frame) is performed. It cannot be tilted, that is, the opening / closing member cannot be closed. That is, there is a concern that a dedicated key is required in the assembly factory and the work process is increased, so that the burden on the worker increases.

  However, according to the configuration of the sixth aspect, in a state where the opening / closing member is opened, the contact piece can be displaced from the contact position to the non-contact position side by manual operation. In other words, when the open / close member is closed with respect to the base member, the connecting rod cannot be moved in the unlocking direction unless the key is used, but when the open / close member is open, in addition to the unlocking operation using the key, The connecting rod can also be moved in the unlocking direction by displacing the contact piece to the non-contact position side. That is, even when the adjustment work inside the gaming machine is performed, even when the connecting rod moves in the locking direction, the contact member is displaced, so that the hook member can be removed without performing the unlocking operation with the key. Can be tilted. Also, when the locking device is assembled at the assembly factory, the locked state can be released without using a key.

  Means 7: In addition to the constitution of means 6, the gaming machine further comprises an unauthorized operation preventing part that shields the abutting piece when the opening and closing member is closed and prevents a direct operation on the corresponding piece. . The unauthorized operation preventing unit may be a dedicated member for shielding the contact piece, but an existing member can also be used.

  By the way, according to the configuration of the means 6, it is possible to move the connecting rod in the unlocking direction by displacing the contact piece to the non-contact position side. The possibility of being done arises. In other words, when the contact piece is directly operated by a wire such as a wire and moved to the non-contact position with the opening and closing member closed, the unlocking operation can be performed on the eaves member along with the unauthorized operation. Become.

  However, according to the structure of the means 7, when the opening / closing member is closed, the contact piece is shielded by the unauthorized operation preventing portion and is prevented from being directly operated by a wire such as a wire. For this reason, when the open / close member is closed, the contact piece is prevented from being displaced to the non-contact position. That is, the locked state of the flange member can be ensured.

  Means 8: In addition to the configuration of means 7, the unauthorized operation preventing portion is provided on the side of the opening / closing member or the base member having the locked portion, and the contact is made when the opening / closing member is closed. A gaming machine characterized in that it is arranged at a position to shield the piece.

  According to the configuration of the means 8, since the unauthorized operation preventing portion is provided on the side having the locked portion, in the state in which the opening and closing member is opened, the contact piece is not directly shielded and is not directly covered. Enables operation. That is, it is possible to perform the work without the unauthorized operation preventing unit, and it is possible to prevent the workability from being deteriorated by the unauthorized operation preventing unit.

  Means 9: In addition to the constitution of means 7, the unauthorized operation preventing portion is provided on the side of the opening / closing member or the base member having the contact piece, and when the opening / closing member is closed, the contact piece A game machine characterized by shielding only a direction in which an unauthorized operation medium such as a wire may enter. Here, the “direction in which the unauthorized operation medium may enter” refers to an intrusion direction when an unauthorized operation medium such as a wire rod enters the vicinity of the contact piece from the outside of the gaming machine by an unauthorized operation. When the contact piece is disposed on the opening / closing member side, the contact piece passes between the base member and the opening / closing member and is directed to the front side from the back side of the opening / closing member.

  According to the configuration of the means 9, the unauthorized operation preventing portion is provided on the side having the contact piece, but is configured to shield only the direction in which the wire or the like may enter the contact piece. Yes. In other words, since the other direction is not shielded, the contact piece can be directly operated by opening the opening / closing member. In addition, since the unauthorized operation prevention part can be arranged in the vicinity of the contact piece (right side, right behind, etc.), it is possible to unitize including the unauthorized operation prevention part, and handling and assembly are easy. Become.

  Means 10: In addition to the structure of means 9, the unauthorized operation preventing part is a component part of the locking mechanism. Here, when the “lock mechanism” includes, for example, an abutting piece and a convex portion that abuts on the abutting piece, the convex portion may be used as an unauthorized operation preventing portion.

  According to the means 10, since one component part of the lock mechanism is used, it is not necessary to separately provide an unauthorized operation preventing part, and it can be configured inexpensively and easily. In addition, since it is arranged in the vicinity of the contact piece, it is possible to reliably prevent the unauthorized operation medium from entering even if it is relatively small.

  Means 11: In addition to any one of the means from means 1 to means 10, when the scissor member is displaced to the detachment side by the unlocking operation of the key, the scissor member regardless of the operation of the key performed thereafter A gaming machine, further comprising a detachment holding mechanism that holds the wing on the detachment side.

  By the way, the means 1 to means 10 are configured to maintain the scissors member on the disengagement side only when the unlocking operation with the key is continued (that is, only when the biasing operation is performed in a predetermined direction), that is, with the hand from the key. When separated, the structure in which the flange member is displaced to the locking side can be employed. However, according to this configuration, when adjusting the inside of the gaming machine or the like, the key urging operation must always be continued, or the unlocking operation must be performed again when the opening / closing member is closed. This is because when the hook member is in the locked state, the locking mechanism is actuated and the displacement to the disengagement side is prohibited, and when the opening and closing member is closed as it is, the hook member collides with the locked portion and the hook member or the hooked member is engaged. This is because the stop portion may be damaged. When the key urging operation is continued as described above, one hand is blocked by the operation, and there is a possibility that the adjustment work becomes difficult. On the other hand, when the unlocking operation is performed again, the adjustment work is facilitated. However, since an operation that was not necessary in the past is necessary, the opening / closing member is closed without performing an appropriate unlocking operation. There is a risk of damaging members.

  However, according to the configuration of the means 11, when the hook member is displaced to the detachment side by the unlocking operation of the key, the hook member is held on the detachment side by the detachment holding mechanism. That is, even if the hand is released from the key, the collar member does not return to the locking side. For this reason, even if adjustment work is performed with both hands, the opening / closing member can be closed without performing the unlocking operation again. Therefore, the burden on the operator is reduced, collision between the eaves member and the locked portion is avoided, and damage to the eaves member and the like can be prevented.

  Means 12: In addition to the constitution of means 11, the collar member is supported by a shaft so as to be tiltable, and is latched and detached from the locked portion by the tilting, and the transmission mechanism includes the collar member And a connecting rod that moves in the unlocking direction in accordance with the unlocking operation of the key, and the detachment holding mechanism returns the connecting rod that has moved in the unlocking direction to the locking direction. A gaming machine comprising return prevention means for preventing this.

  According to the configuration of the means 12, when the key is unlocked, the connecting rod moves in the unlocking direction, and the movement is transmitted to the rod member. Then, the collar member tilts and is detached from the locked portion. On the other hand, in a state in which the hook member is detached from the locked portion, the return blocking means prevents the connecting rod from returning in the locking direction, thereby maintaining the state of the hook member. In this way, since the displacement of the hook member is prevented by preventing the movement of the connecting rod, the connecting rod can be directly connected to the flange member.

  Means 13: In addition to the constitution of means 12, the return preventing means is provided between a locking position where movement is restricted by locking and a non-locking position where movement is not restricted with respect to the connecting rod moving in the locking direction. And a second elastic member for urging the locking piece toward the locking position.

  According to the structure of the means 13, even if the connecting rod tries to move in the locking direction, it is locked by the locking piece and prevented from moving. Moreover, since this latching piece is always urged | biased by the latching position side with the elastic member, the movement of a connection rod can be blocked | prevented reliably.

  Means 14: In addition to the structure of means 13, holding that displaces the locking piece from the locking position to the non-locking position side against the elastic force of the second elastic member when the opening / closing member is closed A gaming machine, further comprising a release portion and a third elastic member that urges the connecting rod in the locking direction.

  By the way, according to the structure of the means 13, since the locking piece prevents the connecting rod from moving in the locking direction, the locking piece is locked at the locking position when locking after the opening / closing member is closed. It is necessary to displace from to the non-locking position side. As this mechanism, for example, it is conceivable to include a lock transmission mechanism that transmits the operation of the lock according to the operation of the key to the locking piece and displaces the locking piece to the non-locking position side. However, according to this mechanism, a locking operation with a key is required, and there is a risk of forgetting to lock. In addition, the structure of the locking device becomes complicated, and there is a concern that the device will be enlarged.

  However, according to the configuration of the means 14, when the opening / closing member is closed, the holding piece is displaced from the locking position to the non-locking position side by the holding release portion. That is, the locked state is released by displacing the locking piece against the elastic force of the elastic member. Moreover, since the connecting rod is urged in the locking direction by the third elastic member, the connecting rod moves in the locking direction when the locked state is released, and the hook member is displaced to the locking side. That is, when the opening / closing member is closed, the flange member is displaced and locked accordingly. For this reason, a locking operation with a key becomes unnecessary, and forgetting to lock is prevented. Further, a complicated mechanism such as transmitting the rotation of the lock to the locking piece can be omitted, and the apparatus can be simplified.

  Means 15: In addition to any one of the means from means 1 to means 14, the base member is an outer frame forming an outer shell, and the opening and closing member is an inner frame supported to be openable and closable with respect to the outer frame. A gaming machine characterized by being.

  According to the configuration of the means 15, it is possible to reliably prevent the inner frame from being opened due to unauthorized unlocking. In particular, because important parts that control the gaming machine, such as a control board, are attached to the inner frame, it is possible to maintain and manage with high safety by preventing unauthorized operation of these parts. Become.

A front frame, at least one front frame hook member that is locked and released from a locked portion provided on the front frame, and the operation of the lock according to the unlocking operation of the key. A gaming machine further comprising a front frame transmission mechanism that transmits to a member and disengages from the locked portion.

  According to the configuration of the means 16, the locking device is provided on the inner frame, and the hook member of the locking device is locked to the locked portion of the outer frame, thereby preventing the inner frame from being opened with respect to the outer frame. Further, the locking device is provided with a front frame hook member, and the front frame hook member is locked to the locked portion of the front frame, thereby preventing the front frame from being released from the inner frame. . That is, the opening of the two opening / closing members is prevented by a set of locking devices. Note that the operation of the lock for detaching the hook member and the operation of the lock for removing the front frame hook member may be a single operation. For example, the operation of the lock may be counterclockwise and counterclockwise. If it is made to respond | correspond to mutually different operation like a rotation direction, it will become possible to detach | separate separately and usability can further be improved.

  Means 17: In addition to any one of the means from means 1 to means 16, the inner frame configured to be openable and closable on the left and right other sides around the left and right one side, and supporting the game board, A game area partitioned into a substantially circular shape by a rail member provided on the front surface of the game board, and the left and right other side portions can be opened and closed centered on the left and right side portions on the front surface side of the inner frame.

FIG. 1 is a front view of the pachinko machine 10, and FIG. 2 is a perspective view showing a state in which an inner frame 12 and a front frame set 14 are opened with respect to an outer frame 11 to be described later.

  As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 is supported on one side of the outer frame 11 so as to be openable and closable. ing. The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. Therefore, the structure can be easily reused as compared with the conventional structure in which the plates are assembled using nails and rivets. In the present embodiment, the outer dimension of the outer frame 11 is 809 mm (inner dimension 771 mm), and the outer dimension in the left and right direction is 518 mm (inner dimension 480 mm). The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. Note that ABS resin is suitable as a material for the inner frame 12 because it is relatively inexpensive, easy to be plated, and resistant to impact. The opening / closing axis of the inner frame 12 is set so as to extend vertically to the opposite side of the handle installation position when viewed from the front of the pachinko machine 10, so that the inner frame 12 can be opened forward with the opening / closing axis as the axis. It has become. That is, the inner frame 12 can be opened without causing the inner frame 12 and the game ball launching handle 18 to interfere with each other. The outer frame 11 may be made of a light metal such as resin or aluminum.

  A lower tray unit 13 is attached to the inner frame 12 at the lowermost portion, and a front frame set 14 is attached so as to cover the inner frame 12 in a range excluding the lower tray unit 13. In particular, an annular rib protruding forward is formed on the periphery of the inner frame 12, and the front frame set 14 is fitted so as to enter the inside of the rib. For this reason, when the front frame set 14 is closed, no gap is formed between the inner frame 12 and the front frame set 14, and insertion of wires or the like due to fraud can be prevented. The lower plate unit 13 is fixed to the inner frame 12 with a fastener such as a screw. The front frame set 14 is attached to the inner frame 12 so as to be openable and closable. Like the inner frame 12, the front frame set 14 is located on the front side with an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10. It can be opened. The front frame set 14 is configured by integrally forming a glass frame portion that supports glass and the upper plate 19, and can improve the strength compared to the conventional structure that is configured as a separate member. Even when the glass frame portion is enlarged as in the pachinko machine 10 of this example, an appropriate strength can be ensured. Further, the front frame set 14 is made of ABS resin like the inner frame 12, and has a characteristic that it is relatively inexpensive, can be easily plated, and is resistant to impact. FIG. 3 is a front view showing a state in which the front frame set 14 is removed from the pachinko machine 10 (however, in FIG. 3, the structure in the game area on the game board 30 is shown as blank for convenience).

  The lower tray unit 13 is provided with a lower tray 15 as a ball receiving tray at a substantially central portion, so that game balls discharged from the outlet 16 can be stored in the lower tray 15. Most of the lower dish unit 13 is formed of ABS resin like the inner frame 12, but the surface layer forming the lower dish 15 and the front panel 22 at the back of the lower dish are particularly flame retardant. Molded with ABS resin. For this reason, this part is difficult to burn. Reference numeral 17 denotes a ball removal lever for discharging the game ball in the lower tray 15 downward. A game ball launching handle 18 is disposed on the right side of the lower plate 15 so as to protrude to the front side. Reference numeral 241 denotes a sound output port from the speaker. An ashtray 23 is provided on the left side of the lower plate 15. Note that the ashtray 23 is cantilevered on the left side surface of the lower plate 15, and can be rotated until the upper surface opening portion faces downward with an open / close axis extending in the left-right direction as an axis. In other words, it is possible to discharge the butts contained in the ashtray 23 by the turning operation.

  On the other hand, the front frame set 14 above the lower plate 15 is integrally provided with a glass frame portion for supporting glass and an upper plate 19 as a ball tray. Here, the upper tray 19 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device while aligning them in a line. In a conventional pachinko machine, a front decorative frame that can be opened and closed with respect to the inner frame is provided below the glass frame, and an upper plate is provided on the front decorative frame, but the front decorative frame is omitted in the present embodiment. The upper plate 19 is provided directly to the front frame set 14. Similar to the lower plate 15, the upper plate 19 has a structure in which the surface layer is formed of flame-retardant ABS resin.

  In FIG. 3, the inner frame 12 is mainly composed of a resin base 20 whose outer shape is rectangular. A substantially circular window hole 21 is formed at the center of the resin base 20, and a substantially square wiring hole 24 is formed at the upper left side of the resin base 20. A game board 30 is detachably mounted on the rear side of the resin base 20. The game board 30 is made of a rectangular plywood, and is attached in a state in which the peripheral edge thereof is in contact with the back side of the resin base 20 (inner frame 12). Accordingly, a substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20. The game board 30 also has a wiring hole 24 a formed on the upper left side, and overlaps the wiring hole 24 of the resin base 20. The vertical length of the game board 30 is 476 mm, and the horizontal length is 452 mm (same size as before).

  An opening switch 25 is attached above the wiring hole 24 in the resin base 20 so as to detect that the front frame set 14 is opened. Also, a grounding metal part 26 partially protruding forward is provided on the upper right side of the resin base 20, and when the front frame set 14 is closed, the reinforcing plate 132 of the front frame set 14 (see FIG. 5). And the reinforcing plate 132 is grounded.

  Next, the configuration of the game board 30 will be described with reference to FIG. The game board 30 is provided with a general winning port 31, a variable winning device 32, a first starting port 34, a second starting port 33, a variable display unit 35 and the like arranged in a through hole formed by router processing. 30 It is attached from the front side with wood screws or the like. As is well known, a game ball enters the general winning port 31, the variable winning device 32, and the second starting port 33, and a predetermined number of prize balls enter the upper plate 19 (or the lower plate 15) by the output of a detection switch described later. Will be paid out. In addition, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices etc. are guided through the out port 36 to a ball discharge path (not shown). It has become. The game board 30 is provided with a large number of nails for appropriately dispersing and adjusting the falling direction of the game balls, and various members (acts) such as a windmill.

  The variable display device unit 35 is provided with a first symbol display device 41 for variably displaying the first symbol and a second symbol display device 42 for variably displaying the second symbol. The first symbol display device 41 includes a first symbol display unit 43 and a holding lamp 44, and the display symbol (first symbol) by the display unit 43 varies each time the game ball passes through the first starting port 34. Let The number of times that the game ball passes through the first start opening 34 is held up to a maximum of 4 times, and the number of times of holding is lit and displayed by the hold lamp 44.

  The second symbol display device 42 is configured as a liquid crystal display device, and the display content is controlled by a display control device 45 (see FIG. 7). The second symbol display device 42 displays, for example, three symbol rows of left, middle and right. Each symbol row is constituted by a plurality of symbols, and these symbols are variably displayed on the second symbol display device 42 so as to be scrolled for each symbol row. Each time the game ball wins the second start opening 33, the display symbol (second symbol) is changed. The number of times that the game ball has passed through the second starting port 33 is held up to a maximum of 4 times, and the number of times of holding is lit and displayed by the hold lamp 46. In the present embodiment, the second symbol display device 42 (liquid crystal display device) includes an 8 inch large liquid crystal display. The variable display device unit 35 is provided with a center frame 47 so as to surround the second symbol display device 42.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is repeatedly operated between an open state in which a game ball is easy to win and a normal closed state in the event of a big win. ing.

  The game board 30 is provided with a rail unit 50 for guiding the game ball launched from the game ball launching device to the upper part of the game board 30 and is fired as the game ball launching handle 18 is rotated. The game balls are guided to a predetermined game area through the rail unit 50. The rail unit 50 includes a rail base unit 50a having an inner rail portion 51 and an outer rail mounting portion 52 which are formed of a ring-shaped resin molded product and are integrally formed inside and outside, and on the inner side surface of the outer rail mounting portion 52. It is composed of a stainless outer rail 55 which is attached and has a long shape. The inner rail portion 51 is formed in a substantially annular shape except for about ¼ of the upper portion, and an outer rail mounting portion 52 is formed so that a part (mainly the left side portion) faces the inner rail portion 51. . In such a case, a guide rail is formed by the inner rail portion 51 and the outer rail mounting portion 52 (outer rail 55), and each of the rails 51 and 52 is formed by a portion (a portion on the left side) parallel to each other at a predetermined interval. A guide passage is formed. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened. Further, the outer rail 55 is provided in order to make the flight of the game ball smoother.

  A return ball preventing member 53 is attached to the tip of the inner rail portion 51 (the upper left portion in FIG. 4). As a result, it is possible to prevent a situation in which the game ball once guided from the ball guide passage between the inner rail portion 51 and the outer rail attachment portion 52 to the upper portion of the game board 30 returns to the ball guide passage again. It has become. Further, a return rubber 54 is attached to the outer rail mounting portion 52 at a position corresponding to the maximum flying portion of the game ball (upper right portion in FIG. 4: a portion corresponding to the tip of the outer rail mounting portion 52). . Therefore, the game ball launched at a predetermined momentum or more hits the return rubber 54 and is rebounded while being braked.

  An arc-shaped flange 56 projecting outward is formed on the outer peripheral portion of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into a plurality of through holes formed in the flange 56. The rail unit 50 can be fastened to 30. In particular, the interval between fastening by screws or the like is narrower on the launch side, and the strength against the launch of the game ball is secured by firmly fastening to the game board 30. Furthermore, in the present embodiment, the top, bottom, left, and right ends of the rail unit 50 are formed in a substantially straight line (flat) when viewed from the front. That is, the flange 56 is cut off at each of the upper, lower, left and right ends of the rail unit 50, and the rail diameter can be expanded in a limited area in the pachinko machine 10, that is, the game area on the game board 30 can be expanded. ing.

  A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail portion 51 and the outer rail attachment portion 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail portion 51 to the lower end portion of the rail unit 50, and a foul ball that flows backward in the ball guide passage without reaching the game area is a foul ball passage 63 (see FIG. 3). To lead to. Note that the lower right corner and the lower left corner of the game board 30 are spaces for directly sticking seals and plates (S1, S2 in the figure) such as certificate stamps, etc., in order to secure this attachment space. The notches 58 and 59 are formed in the flange 56.

  Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner peripheral portion (inner and outer rails) of the rail unit 50. In particular, in this embodiment, the game area partitioned on the board surface of the game board 30 is far more than conventional. It is greatly configured. In the present embodiment, the distance from the uppermost point of the outer rail mounting portion 52 to the lower part of the game board 30 is 445 mm (58 mm longer than the conventional product), and the inner rail portion 51 extends from the extreme left position of the outer rail mounting portion 52. The distance to the extreme right position is 435 mm (50 mm longer than the conventional product). The distance from the extreme left position of the inner rail portion 51 to the extreme right position of the inner rail portion 51 is 418 mm.

  In the present embodiment, when the game area is viewed from the front of the pachinko machine 10, the area of the guide rail that is a parallel part of the inner and outer rails 51 and 52 among the areas surrounded by the inner rail portion 51 and the outer rail mounting portion 52. The area is excluded. Accordingly, since the game area does not include the guide rail portion, the left limit position toward the game area is specified not by the outer rail mounting portion 52 but by the inner rail portion 51. Similarly, the right limit position toward the game area is specified by the inner rail portion 51. The lower limit position of the game area is specified by the lower end position of the game board 30. Further, the upper limit position of the game area is specified by the outer rail mounting portion 52.

  Therefore, in the present embodiment, the width of the game area (maximum width in the left-right direction) is 418 mm, and the height of the game area (maximum width in the vertical direction) is 445 mm. Here, the width of the gaming area is preferably at least 380 mm. More preferably, it is 390 mm or more, 400 mm or more, 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and further 460 mm or more. Of course, it may be 470 mm or more. That is, the width of the game area is preferably as large as possible from the viewpoint of expanding the game area. The height of the game area is preferably at least 400 mm. More preferably, it is 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and more preferably 460 mm or more. Of course, it is good also as 470 mm or more, 480 mm or more, and 490 mm or more. That is, the width of the game area is preferably as large as possible from the viewpoint of expanding the game area. In addition, about the combination of the said width | variety and height, it is good also as what combined the said numerical value arbitrarily.

  In the present embodiment, the ratio of the area of the game area to the surface of the game board 30 is about 70%, which is much larger than the conventional area ratio. Note that the area ratio of the game area to the surface of the game board 30 has been only about 50% in the past, so it can be said that the game area is considerably expanded on the premise that the game board 30 is shared. It should be noted that the external shape of the pachinko machine 10 is almost uniform among manufacturers for the convenience of installation in the game hall, and in the situation where the size of the game board 30 must be the same, the surface of the game board 30 as described above. Increasing the ratio of the area of the gaming area to about 20% is very significant from the viewpoint of expanding the gaming area. Here, the ratio is preferably at least 60% or more. More preferably, it is 65% or more, More preferably, it is 70% or more. Further, if it is 75% or more exceeding the case of this embodiment, it is more desirable. Furthermore, it may be 80% or more.

  Further, the ratio of the area of the game area to the area of the front side of the entire pachinko machine 10 is about 40%, which is a much larger area ratio than before. The area ratio of the game area to the area of the front side of the entire pachinko machine 10 is desirably 35% or more. Of course, it may be 40% or more, 45% or more, or 50% or more.

  In addition, the 1st starting port 34 located in the both sides of the variable display apparatus unit 35 has a guide mechanism in which the game ball which passed this 1st starting port 34 is approached toward the center. Thereby, even when the game area is expanded in the left-right direction, the game ball can be guided toward the center second starting port 33 and the variable winning device 32, and the game area is expanded. As a result, a decrease in interest due to the difficulty of winning the game ball is suppressed. Furthermore, by extending the game area in the left-right direction, a windmill, a first start port 34, a plurality of nails (guide nails for guiding a game ball to the center), and other accessories are arranged. Thus, the behavior of the game ball in the game areas on the left and right sides of the variable display device unit 35 can be made more interesting. Further, since the game area is also expanded in the vertical direction, it is possible to arrange various windmills, the first start port 34, a plurality of nails, and other accessories, and the game in the vertical direction in the game area. The behavior of the sphere can be made even more interesting.

  Returning to the description of FIG. 3, in the resin base 20, below the window hole 21 (game board 30), a launch rail 61 for guiding the game ball immediately after being launched from the game ball launcher is attached. Yes. The firing rail 61 is fixedly attached to the resin base 20 via a metal plate 62 behind the firing rail 61, and is configured to extend linearly at a predetermined firing angle (launch angle). In particular, in the pachinko machine 10 of this example, since the game board 30 is larger than the conventional one, the launch position of the launch rail 61 is reduced while lowering the launch position of the game ball so as to match the curvature of the rail unit 50. To make it longer. The launch rail 61 is formed in a substantially M-shaped cross section with a wide width, and stabilizes the launch of the game ball. Accordingly, the game ball that is launched in accordance with the turning operation of the game ball launching handle 18 is first launched obliquely upward along the launch rail 61, and thereafter, into the predetermined game area through the ball guide path of the rail unit 50 as described above. Guided.

  In the case of this pachinko machine 10, it has already been described that the game area is greatly expanded compared to the conventional case, but under such a configuration, the curvature of the guide rail must be reduced, so that the launch ball is stabilized. Need some ingenuity. Therefore, in the present embodiment, the launch position of the game ball is lowered and the inclination angle (launch angle) of the launch rail 61 is made somewhat larger than that of the existing one (that is, the launch rail 61 is raised) to further launch. The length of the rail 61 is made longer than the existing one so as to ensure a sufficiently long ball guiding distance. Thereby, the game ball launched from the game ball launching device can be guided to the guide rail in a more stable state. Particularly in this case, the launch rail 61 is formed so as to extend from the launch position of the game ball launcher to a position beyond the center position (out port 36) of the game area.

  Further, there is a gap of a predetermined interval between the firing rail 61 and the rail unit 50 (guidance rail), and a foul ball passage 63 is formed below the gap. Therefore, if the game ball fired from the game ball launching device does not reach the return ball prevention member 53 and returns to the inside of the guide rail as a foul ball, the foul ball passes through the foul ball passage 63 to the lower plate 15. To be discharged. Incidentally, in the case of the present embodiment, the length of the firing rail 61 is about 240 mm, and the length of the gap at the tip of the firing rail (the length on the extension line of the firing rail 61) is about 40 mm.

  When the foul sphere flows backward in the guide rail, most of the foul sphere flows along the outer rail mounting portion 52 and drops downward when reaching the lower end of the outer rail mounting portion 52. May be ramped in the guide rail and jump to the inner rail 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage 63. Thereby, all of the foul balls are surely guided to the foul ball passage 63. This suppresses interference between the foul ball and the next game ball to be launched.

  Although detailed disclosure of the drawings is omitted, one game ball is supplied to the game ball launching device one by one from the ball outlet on the front frame set 14 side (ball outlet leading from the most downstream portion of the upper plate 19). At this time, since the launch position of the game ball is lowered in the present embodiment, the drop from the exit of the ball on the front frame set 14 side to the launch position becomes large, but in the vicinity of the base end portion of the launch rail 61, its right side and Guide members 65 and 66 were installed on the front side. Thereby, the game ball supplied from the ball exit on the front frame set 14 side is always set at a predetermined launch position, and a stable launch operation can be realized. In addition, the game ball launcher is provided with a hitting ball basket, and the game ball is shot with the rotation of the hit ball bowl around the shaft portion. Therefore, while aiming to reduce the weight of the hitting ball by changing the material to light metal such as aluminum and reducing the size of the shaft, the head portion of the hitting ball (on the side opposite to the shaft) is secured to ensure sufficient firing force. A weight is provided at the end. Thereby, sufficient and stable launch of the game ball can be realized. By providing the weight portion of the hitting ball projecting upward, it is possible to easily pick or hit the hitting ball, and it is easy to adjust the hitting strength of the hitting tip.

  In addition, the code | symbol 67 in FIG. 3 is the discharge port connected to the upper plate 19, and a game ball is discharged to the upper plate 19 through this discharge port 67. FIG. An opening / closing shutter 68 having an opening / closing shaft extending in the left-right direction on the lower side is attached to the discharge port 67, and the shutter 68 is supported so as to be opened forward with the opening / closing shaft as an axis. Further, the shutter 68 is biased to the closed side by an elastic body such as a spring and presses the upper side against the biasing force of the elastic body to be in a substantially horizontal state and opens the discharge port 67. That is, in the state where the front frame set 14 is opened (the state shown in FIG. 3), the shutter 68 closes the discharge port 67 by the urging force of the elastic body, thereby preventing the game ball from being discharged. On the other hand, in a state where the front frame set 14 is closed, the shutter 68 is pushed open by the ball passage rod 69 (see FIG. 2) protruding from the back surface of the front frame set 14, and the game ball can be discharged. Accordingly, in the present pachinko machine 10 in which the front decorative frame is omitted and the upper plate 19 is directly provided to the front frame set 14, the game balls in the payout passage and the like are spilled off when the front frame set 14 is opened. Inconvenience can be prevented.

  The resin base 20 is provided with a substantially rectangular small window 71 at the lower right portion of the window hole 21. Accordingly, a seal or the like (S1 in FIG. 4) stretched at the lower right corner of the game board 30 can be viewed through the small window 71. Further, a sticker or the like can be attached from the small window 71.

  Further, support metal fittings 81 and 82 are attached to the left end portion of the inner frame 12 in FIG. 3 as a support mechanism for the front frame set 14. The upper support fitting 81 is provided with a support hole 83 having a notch on the front side of the figure, and the lower support fitting 82 is provided with a protruding shaft 84 protruding in the vertical direction.

  Next, the front frame set 14 will be described with reference to FIGS. FIG. 5 is a rear view of the front frame set 14. The front frame set 14 is formed with a substantially elliptical window 101 so that most of the game area can be visually recognized from the outside. Specifically, the window portion 101 has a shape in which a substantially central portion on the left and right sides is curved relatively gently as compared with the upper and lower sides. The substantially central portion may be linear. In the present embodiment, the distance between the upper end of the window portion 101 (the uppermost portion of the outer rail mounting portion 52 and the upper end of the game area) and the upper end of the front frame set 14 (the so-called upper and lower width of the upper frame portion) is 61 mm. It is significantly shorter than the prior art with an upper frame width of about 85 mm to 95 mm. As a result, the upper area of the game area can be easily secured, and the large variable display device unit 35 can also be arranged relatively upward. The distance between the upper end of the front frame set 14 is desirably 80 mm or less, more desirably 70 mm or less, and further desirably 60 mm or less. Of course, as long as a predetermined strength can be ensured, it may be 50 mm or less.

  Further, the shortest distance between the left end of the window portion 101 and the left end of the front frame set 14 when viewed from the front of the pachinko machine 10 (the left-right width of the so-called left side frame portion: shown on the right side in FIG. 5), The frame width on the opening / closing axis side is set to be relatively large in order to increase the strength and support strength of the front frame set 14 itself. In this case, as apparent from comparison between FIGS. 1 and 3, not only the left end portion of the outer rail mounting portion 52 but also the left end portion of the inner rail portion 51 is not limited to the left side in the state where the front frame set 14 is closed. Covered by the part frame part. That is, at least a part of the guide rail overlaps and is covered with the left frame portion of the front frame set 14 when viewed from the front of the pachinko machine 10. Even if it becomes difficult to visually recognize the game ball in this way, it is only a passing point where the game ball is guided to the game area, and it is difficult to see the game ball in the game area where the player mainly enjoys the game. It doesn't mean. Therefore, there is no trouble in actual game. Moreover, while such a trouble does not arise, sufficient intensity | strength and support strength of the front frame set 14 are securable. Incidentally, the distance in the left-right direction between the left end position of the outer rail mounting portion 52 and the left end position of the outer frame 11 when viewed from the front of the pachinko machine 10 is 21 mm, the right end position of the game area (the right end position of the inner rail portion 51) and the outside The distance in the left-right direction from the right end position of the frame 11 is 44 mm.

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state at the time of big hit or predetermined reach. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting means such as an LED is provided. In the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks when the jackpot is informed that the jackpot is being hit. Further, the upper plate 19 is also provided around the upper plate 19 with an upper plate illumination unit 104 having a built-in light emitting means such as an LED. In addition, on the left and right sides of the central illumination unit 103, there are provided a prize ball lamp 105 that is lit during the payout of a prize ball and an error display lamp 106 that is lit when a predetermined error occurs. In addition, a transparent resin is attached so that a portion of the inner frame 12 surface, the surface of the game board 30 and the like, especially the stamp S1 directly attached to the game board 30 can be visually recognized so as to be adjacent to the lower end of the annular illumination part 102. A small window 107 is provided. Note that the surface of the transparent resin in the small window 107 has a planar shape so that the certificate paper S1 can be recognized from the outside by a reading device.

  In addition, a ball lending operation unit 120 is disposed below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. If the ball lending operation unit 120 is operated in a state where a bill or a card is inserted into a card unit (ball lending unit) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. . The ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. Is done. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. Note that the ball lending operation unit 120 is not necessary for a pachinko machine in which game balls are lent directly to the upper plate 19 from a ball lending device or the like without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  Various reinforcing members made of metal are provided on the back side of the front frame set 14 so as to surround the window portion 101. Specifically, as shown in FIG. 5, reinforcing plates 131, 132, 133, and 134 are respectively attached to the back side of the front frame set 14 and on the top, bottom, left, and right sides of the window portion 101. These reinforcing plates 131 to 134 are connected in contact with each other, but resin parts 135 for avoiding direct contact are interposed at the connecting portions of the left and upper reinforcing plates 132 and 133 in the drawing. Thereby, the reinforcement board 132 and the reinforcement board 133 are electrically insulated, a conductor does not become loop shape, and generation | occurrence | production of the noise by a magnetic field is suppressed. The right reinforcing plate 131 in FIG. 5 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof. The engaging claw 131a is a hole portion of the inner frame 12 with the front frame set 14 closed. It is comprised so that it may be engaged with 12a (refer FIG. 3). With this configuration, the front frame set 14 is configured to include the upper plate 19, and even if the upper and lower pivot support positions are extended, the front frame set 14 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front frame set 14 is suppressed.

  The lower reinforcing plate 134 is provided with a resin rail side wall member 136 at a position facing the firing rail 61 (see FIG. 3). The rail side wall member 136 becomes the side wall of the firing rail 61 when the front frame set 14 is closed. Therefore, the game ball is prevented from spilling from the launch rail 61.

  The reinforcing plates 131 to 134 described above also have a function as a metal frame for supporting the glass, and a part of the reinforcing plates 131 to 134 is folded back to form a glass holding groove. The glass holding grooves are formed in two rows on the front and rear sides, and a pair of front and rear glasses 137 having a rectangular shape are held in each glass holding groove. Thereby, the two glass 137 is attached to the front and back at a predetermined interval.

  As described above, in the pachinko machine 10 according to the present embodiment, the game area is expanded. Therefore, when the front frame set 14 is closed, one of the guide rails configured by the inner and outer rails 52 and 53 is used. The part is covered with the front frame set 14. Therefore, in the guide rail, a portion where the front open portion cannot be covered with the glass 137 is formed. In such a case, for example, when the game ball launched from the game ball launching device returns without reaching the return ball prevention member 53, the game ball spills out (jumps out) from the guide rail, and the outer rail mounting portion 52 There is a risk of being caught between the glass 137 and the like. Therefore, in the present embodiment, a rail cover 140 for covering the front side open portion of the guide rail is attached to the front frame set 14.

  The rail cover 140 is a substantially flat plate having a substantially arc shape, and is formed of a transparent resin. The rail cover 140 has an arc shape corresponding to the shape of the guide rail, and covers the section from the base end portion of the guide rail to the vicinity of the tip end portion along the peripheral edge of the window portion 101. It is attached to the back side of the set 14. In particular, the size and shape of the rail cover 140 on the inner diameter side substantially match those of the inner rail portion 51. When the rail cover 140 is attached, the surface side of the rail cover 140 is in contact with the glass 137. When the front frame set 14 is closed, the back surface of the rail cover 140 covers almost the entire area of the guide rail. Thereby, the collision of the game ball with the glass 137 can be prevented in most sections of the guide rail. Therefore, adverse effects such as breakage due to contact with the glass 137 can be suppressed.

  Further, a portion where the guide rail protrudes from the side edge portion of the glass 137 is provided at the right end portion of the rail cover 140 (that is, the portion which becomes the right end in the state of FIG. 5 where the rail cover 140 is attached to the front frame set 14). A covering portion 141 for covering is provided. Thereby, it is possible to prevent the occurrence of problems such that the game ball spills out of the guide rail (jumps out) or gets caught between the outer rail mounting portion 52 and the glass 137.

  Further, on the back side of the rail cover 140, a ridge 142 is formed that extends in an arc along the inner edge of the rail cover 140 and protrudes toward the front side of FIG. The ridge 142 is configured to overlap the inner rail 52 substantially integrally with the rim 142 in a state of entering the guide rail when the front frame set 14 is closed. Therefore, for example, even if a wire or the like is intruded through a gap between the front frame set 14 and the inner frame 12 to perform an illegal act, it is very difficult to infiltrate the wire or the like into the game area inside the guide rail. Become. As a result, fraudulent acts performed using a wire or the like can be prevented. In addition, it is good also as a structure which forms the protrusion 142 in a wider range, for example along the whole region of the inner edge of the rail cover 140. According to this structure, it becomes difficult to infiltrate a wire etc. in a wider range, a wire etc. It is possible to more reliably prevent fraud performed using

  Further, support metal fittings 151 and 152 are attached to the right end portion of the front frame set 14 in FIG. 5 (left end portion when viewed from the front of the pachinko machine 10) as a support mechanism for the inner frame 12. Therefore, the front frame set 14 can be opened and closed with respect to the inner frame 12 by assembling the support brackets 151 and 152 on the front frame set 14 side to the support brackets 81 and 82 (see FIG. 3) on the inner frame 12 side. It comes to be installed. In particular, the upper support fitting 81 is provided with a support hole 83 having a notch opened forward, and the lower support fitting 82 is provided with a protruding shaft 84 protruding in the vertical direction. In a state where the front frame set 14 is opened so as to be in a vertical state with respect to 12, the engagement state between the projection shaft 84 and the support bracket 152 is released by lifting the front frame set 14 once, and further, from this state, By pulling the frame set 14 forward, the engagement state between the support hole 83 and the support fitting 153 is released. That is, the front frame set 14 can be removed from the inner frame 12 by the above operation.

  Incidentally, as shown in FIG. 10, the inner frame 12 is provided with a key unit 27 that is unlocked by a key. The inner frame 12 and the front frame set 14, and the front frame set 14 and the outer frame 11 Can be locked to each other. Specifically, as shown in FIG. 2, a hook-like locked portion 271 that protrudes rearward is provided at the right end of the back surface of the front frame set 14 so as to be lined up and down. When the inner frame 12 and the inner frame 12 are overlapped, each locked portion 271 is inserted into a locking portion through-hole 272 formed at the right end of the inner frame 12. On the other hand, the key unit 27 is inserted through the first hook member 273 and the second hook member 274 that are locked and detached from the locked portion 271 and the key hole 275 provided in the lower portion of the inner frame 12. The key operation is transmitted to the first hook member 273 and the second hook member 274 in response to an unlocking operation of the key (for example, a counterclockwise rotation operation), and these are engaged portions 271 of the front frame set 14. And a first key unlocking transmission mechanism 276 that is released from the first key unlocking mechanism.

  On the other hand, on the right side surface of the inner periphery of the outer frame 11, a quadrangular locked portion (not shown) protruding inward is provided side by side. On the other hand, the third hook member 279 and the fourth hook member 280 that extend toward the locked portion 278 and are locked and detached from the locked portion 278 are different from the above. The operation of the key is transmitted to the third hook member 279 and the fourth hook member 280 in accordance with the unlocking operation of the key (for example, the clockwise rotation operation), and these are detached from the locked portion 278 of the outer frame 11. A second key unlocking transmission mechanism 281 is provided. That is, since the key unit 27 is provided with the first key unlocking transmission mechanism 276 and the second key unlocking transmission mechanism 281, when the key is rotated counterclockwise, the right end of the front frame set 14 becomes the inner frame. 12, and only the front frame set 14 can be opened with the support mechanism as an axis. Further, when the key is rotated in the clockwise direction, the inner frame 12 can be rotated about the support fitting 282 as an axis. The first hook member 273 and the second hook member 274, and the third hook member 279 and the fourth hook member 280 are connected by the first key unlocking transmission mechanism 276 and the second key unlocking transmission mechanism 281 respectively. However, even if an unauthorized unlocking operation is performed on any one of the collar members, it is configured not to be transmitted to the other collar member that has not been unlocked. In other words, if an unauthorized unlocking operation is performed on one of the collar members by using a wire rod or the like without using a key, the collar member may be detached from the locked portion. Since the signal is not transmitted to the other hook member that is not present, the hook member continues to be locked to the locked portion. That is, the front frame set 14 or the inner frame 12 is prevented from being opened by an unauthorized unlocking operation.

  Next, a specific configuration of the key unit 27 (locking device) will be described in detail with reference to FIGS. 38 is a side view of the pachinko machine 10, FIG. 39 is a side view of the key unit 27, and FIGS. 40 and 41 are a side view and a rear view showing the upper half and the lower half of the key unit 27, respectively.

  As shown in FIG. 38, the key unit 27 is attached to the first hook member 273 and the second hook member 274 that are locked to the locked portion 271 of the front frame set 14, and the locked portion 278 of the outer frame 11. A third hook member 279 and a fourth hook member 280 to be locked are provided, and the inner frame 12 and the front frame set 14, and the outer frame 11 and the inner frame 12 can be locked, respectively. .

  As shown in FIGS. 39 to 41, the key unit 27 includes a vertically elongated frame body 600, and the frame body 600 is fixed to the inner frame 12. Here, a metal plate bent into a substantially right angle to form an angle is used as the frame 600. In order to distinguish two plate-like portions that are substantially orthogonal to each other in the frame 600, one is referred to as an “attachment portion 601” and the other is referred to as a “support portion 602”. The attachment portion 601 is attached to the back surface of the inner frame 12 by a fastener such as a screw, and the support portion 602 is substantially orthogonal to the back surface.

  A lock that is unlocked by a dedicated key (not shown) is attached to the mounting portion 601. Here, the cylinder lock 603 is used as the lock, but other types of locks may be used. The cylinder lock 603 is operated by a key inserted for unlocking. Here, the cylinder lock 603 is rotated in the clockwise direction when viewed from the front of the pachinko machine 10, and the direction in which the key is turned when the inner frame 12 is opened. The counterclockwise direction is set as the direction in which the key is turned when the front frame set 14 is opened. The cylinder lock 603 includes a lock shaft 604 that rotates in accordance with the operation of the key. A cam plate 607 having a first protrusion 605 and a second protrusion 606 is attached to the lock shaft 604.

  As shown in FIG. 40, a support piece 610 that is vertically bent so as to be parallel to the support portion 602 is formed at the upper portion of the attachment portion 601, particularly at a position corresponding to the locked portion 278 of the outer frame 11. Has been. A third flange member 279 is supported on the support piece 610 by a shaft 611 so as to be tiltable in the vertical direction. Similarly, as shown in FIG. 41, a support piece 612 parallel to the support portion 602 is formed at a lower portion of the attachment portion 601, particularly at a position corresponding to the locked portion 278 of the outer frame 11. A fourth rod member 280 is supported on the piece 612 so as to be tiltable by a shaft 613. The third hook member 279 and the fourth hook member 280 are configured to be locked to the locked portion 278 when being in a substantially horizontal state and to be detached from the locked portion 278 when being tilted upward. Has been. Here, the third hook member 279 and the fourth hook member 280 correspond to the hook member of the present invention, and in particular, the third hook member 279 is the first hook member of the present invention, and the fourth hook member 280 is the present invention. Respectively corresponding to the second collar member.

  Between the support part 602 and each support piece 610,612, the connection rod 615 is arrange | positioned so that a reciprocation is possible to an up-down direction. The upper end portion of the connecting rod 615 is directly connected to the third flange member 279 by the connecting pin 617a, and the lower end portion of the connecting rod 615 is directly connected to the fourth rod member 280 by the connecting pin 617b. The frame 600 is formed with a plurality of restricting projections 616 for restricting the movement of the connecting rod 615 in the front-rear direction and the left-right direction, and the connecting rod 615 is sandwiched by these restricting projections 616. On the other hand, of the reciprocating movement of the connecting rod 615 in the vertical direction, the downward movement is related to unlocking. That is, as the connecting rod 615 moves downward, the third rod member 279 and the fourth rod member 280 are displaced from the state of FIG. 42A to the state of FIG. . Therefore, among the up and down directions that are the reciprocating direction of the connecting rod 615, “downward” is referred to as “unlocking direction” and “upper” is referred to as “locking direction”. Here, the connecting rod 615 corresponds to the inner frame connecting rod of the present invention.

  As shown in FIG. 41, the connecting rod 615 has an elongated shape in the vertical direction, and a rotation transmission portion 620 with which the first protrusion 605 is brought into contact with the rotation of the cam plate 607 is formed in a part thereof. Yes. The cam plate 607 and the rotation transmission unit 620 convert the rotational motion of the lock shaft 604 into a linear motion and transmit it to the connecting rod 615. When the key is rotated in the clockwise direction to open the inner frame 12, the first protrusion 605 comes into contact with the rotation transmitting unit 620 from above and pushes down the connecting rod 615. In this way, the connecting rod 615 is moved in the unlocking direction in accordance with the key unlocking operation. A first coil spring 618 is stretched between the connecting rod 615 and the mounting portion 601, and the connecting rod 615 is biased in the locking direction (upward). That is, when the key is rotated in the clockwise direction, the connecting rod 615 moves in the unlocking direction against the elastic force of the first coil spring 618. Here, the first coil spring 618 corresponds to the third elastic member of the present invention. A combination of the connecting rod 615, the cam plate 607, and the rotation transmission unit 620 is a second key unlocking transmission mechanism 281 and corresponds to the transmission mechanism of the present invention.

  By the way, when the third hook member 279 and the fourth hook member 280 are directly connected to the connecting hook 615, both the hook members 279 and 280 are tilted in conjunction with each other. If either one of them is tilted upward, there is a possibility that the two flange members 279 and 280 are detached from the locked portion 278. In other words, there is a risk that the key unit 27 that should normally be unlocked without using a dedicated key may be unlocked without using the key.

  Therefore, in the present embodiment, a lock mechanism 625 is provided that prohibits the third hook member 279 and the fourth hook member 280 from being displaced toward the detachment side with respect to an unauthorized unlocking operation performed without using a key. Yes. The lock mechanism 625 will be described in detail with reference to FIGS. 43 and 44. 43 is an enlarged rear view around the lock mechanism 625, and FIG. 44 is a side view showing the operation of the lock mechanism 625. The locking mechanism 625 includes a first convex portion 633 and a second convex portion 634 that protrude to the left side (the right side in FIG. 44) from the connecting rod 615, and an abutment piece 627 that can abut on the convex portions 633 and 634. , An attachment piece 629 bent vertically from the lower portion of the contact piece 627 and supported by the attachment portion 601 by the shaft 630, a hooking claw portion 629a formed at the lower end of the attachment piece 629, a hooking claw portion 629a, The second coil spring 631 is stretched between the mounting portions 601. That is, the contact piece 627 and the attachment piece 629 are rotatably supported, and are urged by the elastic force of the second coil spring 631 so that the contact piece 627 contacts the connecting rod 615. In this state, even if the connecting rod 615 attempts to move in the unlocking direction, the lower ends of the first convex portion 633 and the second convex portion 634 formed integrally with the connecting rod 615 are near the end portion of the contact piece 627. Therefore, the connecting rod 615 is prevented from moving downward (unlocking direction). For this reason, even if an unauthorized unlocking operation is performed on the third hook member 279 and the fourth hook member 280, the upward tilting of these hook members 279, 280 is prevented, and as a result, the inner frame 12 Is reliably prevented. Here, a combination of the contact piece 627 and the two convex portions 633 and 634 corresponds to the movement preventing means of the present invention.

  Further, a curved portion 628 that is curved so as to warp with respect to the connecting rod 615 is formed at the upper end of the contact piece 627, and the second protrusion 606 of the cam plate 607 is formed between the curved portion 628 and the connecting rod 615. It has been inserted (see FIG. 44 (a)). For this reason, when the key is rotated in the clockwise direction to open the inner frame 12, the second protrusion 606 rotates while being in contact with the curved portion 628, and the contact piece 627 is rotated about the shaft 630 as a fulcrum. . Thereby, the 1st convex part 633 and the 2nd convex part 634, and the contact piece 627 do not contact | abut, and it becomes possible to move the connection rod 615 in an unlocking direction (refer FIG.44 (b)). That is, the contact piece 627 is biased to the contact position side by the second coil spring 631, but when there is an appropriate key unlocking operation, the contact piece 627 is displaced to the non-contact position side. That is, by displace the contact piece 627 against the elastic force of the second coil spring 631, the locked state is released and the connecting rod 615 can be moved in the unlocking direction. Here, the combination of the second protrusion 606 and the curved portion 628 corresponds to the unlocking portion of the present invention, and the second coil spring 631 corresponds to the elastic member of the present invention.

  The contact piece 627 is disposed at a position where it can be operated when the inner frame 12 is opened. For this reason, in a state where the inner frame 12 is opened, in addition to an appropriate unlocking operation with a key, the contact piece 627 is displaced (rotated) from the contact position to the non-contact position by manual operation. It becomes possible to move the hook 615 in the unlocking direction. Therefore, for example, when the connection rod 615 moves in the locking direction while the adjustment work inside the pachinko machine 10 is being performed, the unlocking operation with the key is performed by rotating the contact piece 627. Without this, the third hook member 279 and the fourth hook member 280 can be tilted. That is, even when the dedicated key is not at hand, the locked state can be released. In addition, since the bending part 628 is formed in the front-end | tip of the contact piece 627, when turning the contact piece 627 by manual operation, a fingertip can be put on the bending part 628.

  In addition, in order to prevent an unauthorized operation to the contact piece 627 when the inner frame 12 is closed, an unauthorized operation prevention that covers the contact piece 627 at a predetermined portion of the outer frame 11 corresponding to the contact piece 627 is prevented. A cover 635 is provided (see FIG. 38). Here, the unauthorized operation prevention cover 635 corresponds to the unauthorized operation prevention unit of the present invention.

  By the way, the key unit 27 includes a detachment holding mechanism 640 that holds the third and fourth hook members 279 and 280 on the release side when the third and fourth hook members 279 and 280 are tilted to the release side. Is provided. The detachment holding mechanism 640 will be described in detail with reference to FIGS. 45 and 46. The disengagement holding mechanism 640 is inserted between the latching piece 645 and the coupling rod 615, and is formed between the latching piece 645 and the coupling rod 615. 615 and a locking member 642 that moves in the vertical direction.

  The locking member 642 is a plate-like rotating piece 641 that is pivotally supported by the shaft 652 with respect to the connecting rod 615, and protrudes rearward (upward in the drawing in FIG. 46) from the upper part of the rotating piece 641. A locking rod 650 extending toward the 645 side, an L-shaped hooking portion 649 positioned below the locking rod 650 and protruding toward the coupling rod 615, and a release protruding rearward from the lower end of the rotating piece 641 And a lever 651. When the connecting rod 615 moves in the locking direction (arrow A direction), the locking rod 650 is inserted (engaged) into the latching groove 646 of the locked piece 645, and this insertion causes the connecting rod 615 to be locked. It is prevented from returning to (arrow B). A third coil spring 648 is stretched between the hook portion 649 and the mounting portion 601, whereby the locking member 642 is biased in the locking direction (clockwise in FIG. 46) with the shaft 652 as a fulcrum. ing. Note that a triangular notch 643 is formed on the end face of the connecting rod 615 corresponding to the hook portion 649, and the hook portion 649 can be displaced with rotation. According to this, as shown in FIG. 46A, when the connecting rod 615 is positioned on the locking side, the locking rod 650 is positioned on the end surface of the locked piece 645 (the upper surface in FIG. 46). Therefore, the movement of the connecting rod 615 is not restricted. However, as shown in FIG. 46B, when the connecting rod 615 is located on the unlocking side, the locking rod 650 faces the latching groove 646. Therefore, the locking rod 650 is inserted into the latching groove 646 by the elastic force of the third coil spring 648, and the movement of the connecting rod 615 (moving in the locking direction) is prevented. Here, the combination of the locking member 642, the third coil spring 648, and the locked piece 645 corresponds to the return prevention means of the present invention, and in particular, the locking member 642 corresponds to the locking piece of the present invention. The third coil spring 648 corresponds to the second elastic member of the present invention.

  The release lever 651 is to displace the locked piece 645 from the locked position to the unlocked position against the elastic force of the third coil spring 648 when the inner frame 12 is closed. That is, the rotating piece 641 is rotated counterclockwise by contact with the inner frame 12, the engagement state between the hooking portion 649 and the hooking groove 646 is released, and the connecting rod 615 is moved (in the locking direction). Movement). At this time, since the connecting rod 615 is urged in the locking direction by the first coil spring 618, the connecting rod 615 moves in the locking direction when the engaged state is released. Thus, by closing the inner frame 12, the connecting rod 615 moves to the locking direction side and is naturally locked. Here, the release lever 651 corresponds to the holding release portion of the present invention.

  On the other hand, as shown in FIGS. 47 and 48, the first flange member 273 is vertically moved by the shaft 653 at a position slightly above the center of the support portion 602, particularly at a position corresponding to the locked portion 271 of the front frame set 14. It is supported so that it can tilt in the direction. Similarly, the second flange member 274 is supported by the shaft 654 so as to be tiltable in the vertical direction at the lower end of the support portion 602, particularly at a position corresponding to the locked portion 271 of the front frame set 14. The first hook member 273 and the second hook member 274 are configured to be locked to the locked portion 271 when in a substantially horizontal state and to be detached from the locked portion 271 when tilted upward. Yes. Here, the 1st collar member 273 and the 2nd collar member 274 are equivalent to the collar member for front frames of this invention.

  As shown in FIGS. 40 and 41, a first connecting rod 660 is disposed between the support portion 602 and the connecting rod 615 so as to be able to reciprocate in the vertical direction. The upper end portion of the first connection rod 660 is connected to the first flange member 273 via the second connection rod 661, and the lower end portion of the first connection rod 660 is connected to the second flange member 274 via the third connection rod 662. It is connected to.

  Further, a fifth coil spring 668 that urges the second connecting rod 661 downward (locking direction) is spanned between the mounting portion 601 and the second connecting rod 661, and the mounting portion 601 and the third connecting rod 662 are spanned. A sixth coil spring 674 that urges the third connecting rod 662 downward (locking direction) is suspended between the two.

  An opening (not shown) is formed in a portion of the connecting rod 615 corresponding to the cam plate 607, and a key is placed in the counterclockwise direction on the first connecting rod 660 located on the back side of the opening. A rotation transmission portion (not shown) that contacts the second protrusion 606 of the cam plate 607 when rotated to the right is formed. For this reason, when the key is rotated counterclockwise in order to open the front frame set 14, the second protrusion 606 comes into contact with the rotation transmitting portion from below and pushes up the first connecting rod 660. In this way, the first connecting rod 660, the second connecting rod 661, and the third connecting rod 662 move in the unlocking direction with the key unlocking operation. Here, a combination of the first connecting rod 660, the second connecting rod 661, the third connecting rod 662, the cam plate 607, and the rotation transmitting portion is the first key unlocking transmission mechanism 276, which is the front surface of the present invention. It corresponds to a frame transmission mechanism.

  Incidentally, the second connecting rod 661 and the first connecting member 273, and the third connecting rod 662 and the second connecting member 274 are directly connected by the connecting pin 669, respectively. 661, and the first connecting rod 660 and the third connecting rod 662 are connected to be extendable and contractable as follows. That is, as shown in FIG. 48, the second connecting rod 661 and the third connecting rod 662 are provided with guide portions extending along the length thereof, and the first connecting rod 660 is provided with an engaging protrusion. The engaging projection is inserted into the guide portion so as to be able to reciprocate. Here, an elongated hole 667 elongated in the vertical direction is formed as a guide portion, and a connection pin 666 fixed to the upper end and the lower end of the first connection rod 660 is provided as an engagement protrusion. The connecting pin 666 is engaged in the long hole 667. Therefore, the second connecting rod 661 and the third connecting rod 662 can be expanded and contracted with respect to the first connecting rod 660 by sliding the connecting pin 666 within the long hole 667.

  For this reason, even if an unauthorized unlocking operation is performed on one of the first hook member 273 and the second hook member 274, the movement of the hook member corresponding to the unlocking operation is not performed on the other hook member that is not unlocked. Transmission to the member can be blocked. That is, when the first connecting rod 660 is moved upward (unlocking direction) by the key from the locked state shown in FIG. 48A, the connecting pin 666 and the elongated hole 667 are engaged with each other. As shown in b), the first connecting rod 660 and the third connecting rod 662 move together, but if the second rod member 274 is displaced to the detachment side by an unauthorized unlocking operation, the connecting pin 666 and Since the long hole 667 is not engaged, only the third connecting rod 662 moves upward as shown in FIG. 5C, and the first connecting rod 660 does not move. Therefore, even if the second collar member 274 is tampered with, it is not transmitted to the first collar member 273, so that the front frame set 14 can be prevented from being opened.

  The key unit 27 is provided with a pressing mechanism that presses a switch (not shown) provided in the front frame set 14 when the front frame set 14 is closed.

In this embodiment, various control boards are divided into two mounting bases to form two control board units, and these control board units are individually attached to the inner frame 12 or the back of the game board 30. ing. In this case, the main board and the sound lamp control board are mounted on one mounting base to form a unit, and the dispensing control board, launch control board, and power supply board are mounted on the other mounting base to form a unit. Here, for convenience, the former unit is referred to as “first control board unit 201”, and the latter unit is referred to as “second control board unit 202”.

  In addition, since the dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally referred to as a back pack, the unit is referred to as a “back pack unit 203”. The detailed configuration of each unit 201 to 203 will be described later. In addition, an external relay terminal board 230 for outputting various signals relating to the gaming state such as “hit signal” to the inner frame 12 is detachably attached by attaching means such as screws and locking claws. It has been. Here, when a simple attachment means such as locking by a locking claw is adopted, the external relay terminal board 230 can be easily attached and detached, and operations such as maintenance can be performed smoothly.

  The first control board unit 201, the second control board unit 202, and the back pack unit 203 are configured so that they can be attached and detached without using any tools or the like in units of units. It is provided and can be opened and closed with respect to the inner frame 12 or the back surface of the game board 30. This is also a device for making it possible to easily check a hidden configuration or the like even if the units 201 to 203 and other configurations are arranged one behind the other.

  Actually, the units 201 to 203 are arranged and attached as shown in the schematic diagram of FIG. In FIG. 8, the first control board unit 201 having a substantially L shape is arranged in the approximate center of the pachinko machine 10, and the second control board unit 202 is arranged therebelow. Further, the back pack unit 203 is arranged in a region partially overlapping the first control board unit 201.

The backpack unit 203 is fixedly held to the main body of the pachinko machine by the fastening part M7 and the locking parts M8, M9. In particular, the locking portion M8 located in the vicinity of the tank 355 is subjected to a relatively large load by the game ball stored in the tank 355, and here, the I-type locking piece is rotated and locked. A structure that is stronger than the ny latch, such as a structure, is used.

  In this case, the development directions of the units 201 to 203 are not the same, and the first control board unit 201 opens to the left when viewed from the back of the pachinko machine 10, whereas the second control board unit 202 and the back pack unit. 203 is configured to open to the right.

  On the other hand, FIG. 9 is a rear view showing the configuration in a state where the game board 30 is assembled to the inner frame 12. FIG. 10 is a perspective view of the inner frame 12 as viewed from the rear, and FIG. 11 is a perspective view of the game board 30 as viewed from the rear. Here, the back side structure of the inner frame 12 and the game board 30 will be described with reference to FIGS.

  The game board 30 is installed in a square frame-shaped installation area surrounded by the resin base 20 and does not fall off by a plurality of (four in this embodiment) locking fixtures 211 and 212 provided on the inner frame 12. So that it is fixed. The locking fixtures 211 and 212 can be manually rotated and can be switched between a fixed position (lock position) and a fixed release position (unlock position). FIG. 9 shows a locked state. The locking fixtures 211 at the three left and right sides of the game board 30 are L-shaped fittings formed by bending metal pieces, and are configured not to protrude outward from the inner frame 12 when the game board 30 is fixed. Note that the locking fixture 212 at one lower portion of the game board 30 is an I-shaped fastener made of resin.

  A variable display device unit 35 is disposed in the center of the game board 30. In the variable display device unit 35, a frame cover 213 made of resin (for example, made of ABS) that covers the center frame 47 (see FIG. 4) from behind is provided to protrude rearward, and at the rear end of the frame cover 213, A second symbol display device 42 as a liquid crystal display device and a display control device 45 are detachably attached in a state where they are overlapped in the front-rear direction. In the frame cover 213, an LED control board for driving LEDs and the like built in the center frame 47 are disposed.

  A back frame set 215 is attached to the back surface of the game board 30 so as to surround the variable display device unit 35. The back frame set 215 is a thin resin-molded product (for example, made of ABS) provided so as to stick to the back surface of the game board 30, and a game ball collecting mechanism for collecting game balls won in various winning openings. Is formed. Specifically, below the back frame set 215, there is one place on the downstream side corresponding to the game board opening of the above-described general winning opening 31, variable winning apparatus 32, and second starting opening 33 (see FIG. 3 respectively). A collection passage 216 is formed to gather in Also, below the game board 30, a discharge passage board 217 made of resin (for example, made of polycarbonate resin) is also attached to the inner frame 12, and a discharge ball is sent to the outside of the pachinko machine 10 in the discharge passage board 217. A discharge passage 218 for guiding is formed. Therefore, as illustrated in phantom lines in FIG. 9, all the game balls won in the general winning opening 31 etc. gather through the collection passage 216 of the back frame set 215, and further, the discharge passage 218 of the discharge passage board 217 is formed. Through the pachinko machine 10. In addition, the out port 36 (see FIG. 3) similarly communicates with the discharge passage 218, and the game balls that have not won any prize opening are discharged to the outside of the pachinko machine 10 through the discharge passage 218.

  In the above configuration, with the lower end surface of the game board 30 as a boundary, a back frame set 215 (collection passage 216) is provided on the upper side, and a discharge passage board 217 (discharge passage 218) is provided on the lower side. The game board 30 is provided without overlapping (overlapping) in the front-rear direction. Therefore, when the game board 30 is removed from the inner frame 12, there is no inconvenience that the discharge passage board 217 prevents the game board 30 from being removed.

  The discharge passage board 217 is provided just behind the upper plate 19 on the front surface of the pachinko machine 10, and a wire or the like is inserted from a ball discharge port (ball passage rod 69 in FIG. 2) leading to the upper plate 19. Further, an illegal act of causing the wire or the like to enter the game area side through a gap between the inner frame 12 and the discharge passage board 217 can be considered. Therefore, in the pachinko machine 10, a plate 219 that extends in front of the pachinko machine 10 so as to almost integrally overlap the inner frame 12 is provided just behind the upper plate 19 of the discharge passage board 217. Therefore, even if a wire or the like tries to enter from the gap between the inner frame 12 and the discharge passage board 217, it is obstructed by the plate 219, and it becomes very difficult to make the wire or the like enter the game area. As a result, it is possible to prevent an illegal act such as forcibly opening the variable winning device 32 (large winning opening) using a wire or the like.

  In addition, on the back surface of the game board 30, a winning detection mechanism for detecting the passage of game balls such as various winning holes is provided.

Further, the specific area switch 222 and the count switch 223 are connected to the special winning opening relay board 227, and the special winning opening relay board 227 is also connected to the main board. On the other hand, the operation port switch 224 is directly connected to the main board without passing through the relay board.

  Although not shown in the drawings, the variable prize winning device 32 is provided with a big prize opening solenoid for opening the big prize opening and a winning ball sorting plate solenoid for guiding the winning ball to a specific area. The port 33 is provided with an operating port solenoid for opening the electric accessory. In FIG. 9, reference numeral 228 denotes a set handle having a hitting ball and the like, and reference numeral 229 denotes a firing motor.

  The detection results detected by the winning detection mechanism are taken into a main board, which will be described later, and a payout command (the number of game balls to be paid out) corresponding to the winning situation is transmitted from the main board to the payout control board. The Then, a predetermined number of game balls are paid out by the output of the payout control board. In such a case, a conventional method (so-called evidence ball method) in which game balls won in various winning openings are once collected in a winning ball processing device and paid out after the winning ball processing device confirms the presence of winning balls one by one in order. Unlike the above, in the pachinko machine 10 according to the present embodiment, the winning of a game ball is electrically detected for each winning opening and the payout is immediately made (that is, the winning ball processing apparatus is abolished in the pachinko machine 10). doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly.

  The back frame set 215 is provided with an attachment mechanism for attaching the first control board unit 201. Specifically, as this attachment mechanism, a support fitting 231 extending in the vertical direction is provided at the lower left corner when viewed from the back of the game board 30, and the support fitting 231 has a pair of upper and lower support holes 231 a on the same axis.

  An attachment mechanism for attaching the second control board unit 202 and the back pack unit 203 is provided on the back surface of the inner frame 12. Specifically, a long support fitting 235 is attached to the right end of the inner frame 12, and the configuration is shown in FIG. As shown in FIG. 12, the support metal fitting 235 has a long plate-like metal fitting body 236, and the support hole 237 for the second control board unit is formed at two lower positions so as to stand up from the metal fitting body 236. At the same time, support hole portions 238 for the back pack unit are formed at two upper positions. Coaxial support holes are formed in the support hole portions 237 and 238, respectively. In addition, as an attachment mechanism for the second control board unit, the inner frame 12 is provided with a pair of upper and lower fastening holes (ny latch holes) 239 at the left end below the game board installation area. As a mounting mechanism for the back pack unit, the inner frame 12 is provided with a pair of upper and lower fastening holes (nylatching holes) 240 at the left end of the game board installation area. However, the support bracket for the second control board unit and the support bracket for the back pack unit can be provided as separate members. Reference numerals 241, 242, and 243 denote rotational fixtures for sandwiching and supporting the back pack unit 203 with the game board 30.

  In addition, in the rear configuration of the inner frame 12, a game ball for distributing a game ball paid out from a payout mechanism, which will be described later, to either the upper plate 19, the lower plate 15, or the discharge passage 218, at the lower right portion of the game board 30. A distribution unit 245 is provided. That is, the opening 245 a of the game ball distribution unit 245 communicates with the upper plate 19, the opening 245 b communicates with the lower plate 15, and the opening 245 c communicates with the discharge passage 218. The game ball distribution unit 245 is configured as a separate member with respect to the back pack unit 203 and is directly fixed to the inner frame 12. That is, even if there is an illegal act on the back pack unit 203, the game ball distributing unit 245 is prevented from being lifted.

  Also, a resin speaker box 246 is attached to the lower end portion of the inner frame 12 to surround the back of the speaker installed on the lower plate 15, and this speaker box 246 improves the sound quality in the low frequency range. ing.

  Next, the first control board unit 201 will be described with reference to FIGS. 13 is a front view of the first control board unit 201, FIG. 14 is a perspective view of the unit 201, FIG. 15 is an exploded perspective view of the unit 201, and FIG. 16 is an exploded perspective view of the unit 201 viewed from the back. .

  The first control board unit 201 has a mounting base 251 having a substantially L shape, and the main control device 261 and the sound lamp control device 262 are mounted on the mounting base 251. Here, the main control device 261 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, a port that communicates with various devices, and various lotteries. It has a main board including a random number generator used, a clock pulse generation circuit used for time counting and synchronization, and the main board is accommodated in a board box 263 made of a transparent resin material or the like. It is configured. The substrate box 263 includes a substantially rectangular parallelepiped box base and a box cover that covers the opening of the box base. The box base and the box cover are connected to each other by a sealing unit 264 so that they cannot be opened, and thereby the substrate box 263 is sealed.

  As long as the sealing unit 264 is configured to connect the box base and the box cover so that they cannot be unsealed, any configuration can be applied. Here, as shown in FIG. 14 and the like, five sealing members are connected. The box base and the box cover are connected so as not to be opened by inserting a locking claw into the long hole of the sealing member. The sealing process by the sealing unit 264 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if the unauthorized opening is performed. It is possible to perform the opening / sealing process again even after the operation. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit 264. And when opening the board | substrate box 263 by the malfunction of the accommodated main board | substrate etc., the connection of the sealing member in which the latching claw was inserted, and another sealing member is cut | disconnected. Thereafter, when the sealing process is performed again, a locking claw is inserted into the long hole of another sealing member. If the history of opening the substrate box 263 is left in the substrate box 263, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 263.

  The voice lamp control device 262 is a voice lamp including, for example, a CPU that controls voice and lamp display in accordance with instructions from the main control device 261 (main board) or the display control device 45, and other ROM, RAM, various ports, and the like. The audio lamp control board is housed in a board box 265 made of a transparent resin material or the like. A power relay board 266 is mounted on the sound lamp control device 262, and power supplied from a power board described later is output to the display control device 45 and the sound lamp control device 262 via the power relay board 266. It is like that.

  The mounting base 251 is formed of a colored (for example, green, blue, etc.) resin material (for example, made of polycarbonate resin), and has two substrate mounting surfaces 252 and 253 that are flat on the surface. These substrate mounting surfaces 252 and 253 extend in a direction orthogonal to each other and are formed with a step in the front-rear direction. However, the mounting base 251 may be a colorless transparent or translucent resin molded product.

  The main control device 261 (main substrate) is arranged in a landscape orientation on one substrate mounting surface 252 and the audio lamp control device 262 (audio lamp control substrate) is arranged in a portrait orientation on the other substrate mounting surface 253. It is arranged in the direction. In particular, the main control device 261 is disposed on the near side when viewed from the back of the pachinko machine 10, and the sound lamp control device 262 is disposed on the back side. In this case, since the substrate mounting surfaces 252 and 253 are formed with steps in the front-rear direction, the control devices 261 and 262 are mounted in a state where the main controller 261 and the sound lamp controller 262 are mounted on the substrate mounting surfaces 252 and 253. Are arranged with a part of them stacked one after the other. That is, as can be seen in FIG. 14 and the like, the main controller 261 is arranged in a state where a part (about 1/3 in the present embodiment) is floated. Therefore, the sound lamp control device 262 can be expanded to an area overlapping with the main control device 261, and the enlargement of the control board can be dealt with satisfactorily. Also, each control device can be installed efficiently. Further, in a state where the first control board unit 201 is mounted on the game board 30, a space is secured behind the board mounting surface 252, and the variable winning device 32 and its electric wiring can be installed without difficulty.

  As shown in FIGS. 15 and 16, the board mounting surface 252 for the main board has horizontally elongated through holes 254 at two positions on the left and right. Correspondingly, the substrate box 263 of the main control device 261 is provided with rotating fixtures 267 at two places on the left and right sides of the back surface thereof. When the main controller 261 is mounted on the board mounting surface 252, the fixing tool 267 is passed through the through hole 254 of the board mounting surface 252, and the fixing tool 267 is rotated in this state to lock the main control apparatus 261. The Therefore, even if the main control device 261 is arranged in a state where it floats as described above, inconveniences such as dropping off of the main control device 261 can be avoided. Further, since the main control device 261 cannot be removed unless the fixture 267 is unlocked from the back side of the first control board unit 201 (board mounting surface 252), it is expected to have a deterrent effect against illegal acts such as board removal. it can. A grid-like rib 255 is provided on the back surface of the substrate mounting surface 252 for the main substrate.

  The mounting base 251 is provided with a pair of upper and lower support shafts 256 on the left end surface of FIG. 14 and the like. By attaching the support shafts 256 to the support fitting 231 shown in FIG. The game board 30 is supported to be openable and closable. Further, the mounting base 251 is provided with a pair of upper and lower nai latches 257 as fasteners at the right end portion and a long hole 258 at the upper end portion, and the nai latch 257 is fitted into the fastening hole 232 shown in FIG. The first control board unit 201 is fixed to the game board 30 by locking the locking claw pieces 233 shown in FIG. The support fitting 231 and the support shaft 256 are in the support shaft portion M1 of FIG. 8, the fastening hole 232 and the ny latch 257 are in the fastening portion M2, the locking claw piece 233 and the long hole 258 are in the locking claw portion M3, Each corresponds.

  Incidentally, as shown in FIG. 8, the first control board unit 201 is attached to the back surface of the game board 30 so that the back pack unit 203 is partially covered. Specifically, the back pack unit 203 covers each of a part of the fastening portion M <b> 2 (the nail latch 257) and the first control board unit 201 of the first control board unit 201. Therefore, if the back pack unit 203 is not removed, all the fastening portions M2 cannot be operated, and the first control board unit 201 cannot be opened and closed with respect to the game board 30. The main controller 261 cannot be removed by an operation from the back side of the substrate unit 201. Therefore, also from this configuration, it is possible to expect a deterrent effect against fraudulent acts such as substrate removal. In addition, not only the back pack unit 203 but also a member that is attached to the game board 30 separately from the first control board unit 201, such as a cover that covers an appropriate unit, at least a part of the first control board unit 201 is provided. The same effect can be expected from the coating.

  Next, the second control board unit 202 will be described with reference to FIGS. 17 is a front view of the second control board unit 202, FIG. 18 is a perspective view of the unit 202, and FIG. 19 is an exploded perspective view of the unit 202.

  The second control board unit 202 has a horizontally long mounting base 301 on which a payout control device 311, a base plate 303, a firing control device 312, a power supply device 313 and a card unit connection board 314 are mounted.

With the substrate, the payout of prize balls and rental balls is controlled. In addition, the launch control board of the launch control apparatus 312 controls the launch motor 229 in accordance with the operation of the game ball launch handle 18 by the player. Is generated and output. The card unit connection board 314 is electrically connected to the ball lending operation unit 120 on the front surface of the pachinko machine and a card unit (not shown). The card unit connection board 314 takes a ball lending operation command from the player and outputs it to the payout control device 311. is there. Note that the card unit connection board 314 is not necessary in a cash machine in which game balls are rented directly from the ball lending device or the like to the upper plate without using a card unit.

  The payout control device 311, the firing control device 312, the power supply device 313, and the card unit connection substrate 314 are respectively configured to be accommodated in substrate boxes 315, 316, 317, and 318 made of a transparent resin material or the like. In particular, in the dispensing control device 311, similarly to the main control device 261 described above, the box base and the box cover constituting the substrate box 315 are connected to each other by the sealing unit 319 so that the substrate box 315 is sealed. .

  The payout control device 311 is provided with a state return switch 321. For example, when the state return switch 321 is pressed when a payout error occurs, such as a ball jam in the payout motor unit, the payout motor is rotated forward and reverse so that the ball jam is eliminated (return to the normal state). It has become.

  The power supply device 313 is provided with a RAM erase switch 323. This pachinko machine 10 has a backup function, so that even if a power failure occurs, it maintains the state at the time of a power failure, and can be restored to the state at the time of a power failure when returning from a power failure (power recovery) It has become. Therefore, if the power is turned off in the normal procedure (for example, when the hall is closed), the state before the power is turned off is stored. If you want to return to the initial state when the power is turned on, turn on the power while holding down the RAM erase switch 323. We are going to throw it in.

  The mounting base 301 is made of, for example, a colorless and transparent resin molded product, and a flat board mounting surface 302 is provided on the surface thereof. In this case, the launch control device 312, the power supply device 313 and the card unit connection board 314 are directly mounted side by side on the board mounting surface 302 of the mounting base 301, and the payout control apparatus 311 is mounted on the board box 317 of the power supply apparatus 313. Has been.

  Further, the mounting base 301 is provided with a pair of upper and lower support shafts 305 at the right end in FIG. 17 and the like.

Each of the air holes 354a has a long hole shape, and the air holes 354a are adjacent to each other at a relatively close position. Therefore, the back surface of the back pack 351 can be easily opened by cutting the resin portion between the adjacent vent holes 354a. That is, a predetermined test or the like can be easily performed by cutting the resin portion between the vent holes 354a to expose the display control device 45 and the like inside.

  In addition, a payout mechanism portion 352 is disposed on the base portion 353 so as to bypass the protective cover portion 354. That is, a tank 355 opened upward is provided at the uppermost portion of the back pack 351, and game balls supplied from the island facilities of the game hall are sequentially supplied to the tank 355. Below the tank 355, for example, a tank rail 356 that has two rows (two rows) of ball passages in the horizontal direction and that is gently inclined toward the downstream side is connected. Further, the tank rail 356 is arranged vertically on the downstream side of the tank rail 356. A case rail 357 is connected. The payout device 358 is provided at the most downstream portion of the case rail 357, and a required number of game balls are paid out appropriately according to a predetermined electrical configuration such as a payout motor. The game balls paid out from the payout device 358 are supplied to the upper plate 19 through the payout passage 359 and the like shown in FIG.

  A vibrator 360 for applying vibration to the tank rail 356 is attached to the tank rail 356. Therefore, if a clogged ball occurs near the tank rail 356, the clogged ball is eliminated by driving the vibrator 360.

  Here, the vibrator 360 is formed as a unit in which a vibration generator such as a vibration motor is built in a casing, and is attached to the side surface of the tank rail 356 using a female screw. The vibrator 360 may be attached to the tank rail with the entire casing in close contact with the tank rail 356. In this example, the vibrator 360 is attached to the tank rail 356 via an elongated attachment leg. Thereby, the whole vibrator 360 formed as a unit vibrates well, and this vibration is smoothly transmitted to the tank rail 356. The mounting legs are integrally projected from the side surface of the tank rail 356, but may be integrally projected from the vibrator 360, or the tank rail 356 and the vibrator 360 may be May be formed individually and interposed between the tank rail 356 and the vibrator 360.

In addition, the rail body 361 is provided with a partition wall 363 extending in the longitudinal direction, and the game balls are divided into two hands by the partition wall 363. The two ball passages partitioned by the partition wall 363 are slightly wider than the diameter of the game ball. One or two ridges 364 are provided on the bottom surface of each spherical passage partitioned by the partition wall 363, and an opening 365 is provided on the side of the ridge 364.

  In addition, a rectifying plate 367 is disposed on the rail body 361 so as to cover the ceiling portion of the downstream half. The rectifying plate 367 has a bowed shape so as to limit the height of the ball passage in the tank rail 356 toward the downstream side, and a convex portion 368 extending in the longitudinal direction is formed on the lower surface thereof. . Thereby, each game ball flowing in the tank rail 356 finally flows out downstream without being stacked up and down. Therefore, even if a large group of game balls flow into the tank rail 356, the game balls are prevented from being bitten and the ball clogging in the tank rail 356 is eliminated. The rail body 367 is formed of a black conductive polycarbonate resin, whereas the rectifying plate 367 is formed of a transparent polycarbonate resin. The rectifying plate 367 is detachably provided, and by removing the rectifying plate 367, maintenance in the tank rail 356 can be easily performed.

  Returning to the description of FIGS. 20 and 21, the payout mechanism unit 352 is provided with a payout relay board 381 that relays a payout command signal from the payout control device 311 to the payout device 358, and takes in the main power from outside.

Lines 530 and 531 are provided. The output of the main controller 261 is connected to the input of the input port 527, and the CPU 521, ROM 522, work RAM 523, and image controller 526 are connected to the output of the input port 527 and one output port is connected via the bus line 530. 528 is connected. A first symbol display device 41 (display unit 43) and an audio lamp control device 262 are connected to the output of the output port 528. Further, an output port 529 is connected to the image controller 626 through a bus line 531, and a second symbol display device 42 which is a liquid crystal display device is connected to an output of the output port 529.

  The CPU 521 of the display control device 45 controls the display of the second symbol display device 42 and the first symbol display device 41 based on the display command transmitted from the main control device 261.

It is displayed on the symbol display device 42.

  The power supply unit 313 includes a power supply unit 541 for supplying power to each part of the pachinko machine 10, a power failure monitoring circuit 542 for monitoring power interruption due to a power failure, and a RAM erase switch connected to the RAM erase switch 323. A circuit 543. The power supply unit 541 supplies necessary operation power to the main control device 261, the payout control device 311 and the like through a power supply path (not shown). As an outline, the power supply unit 541 takes in an AC 24 volt power supply supplied from the outside, and generates a + 12V power supply for driving various switches and motors, a + 5V power supply for logic, a backup power supply for RAM backup, and the like.

Note that operation power (+12 V power, +5 V power, etc.) is supplied to the launch control device 312 via the payout control device 311.

  The power failure monitoring circuit 542 is a circuit for outputting a power failure signal S1 to each NMI terminal of the CPU 501 of the main control device 261 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power failure) has occurred when this voltage is less than 22 volts. The power failure signal S1 is output to the main controller 261 and the payout controller 311. Based on the output of the power failure signal S1, the main control device 261 and the payout control device 311 recognize the occurrence of the power failure and execute the power failure processing (NMI interrupt processing in FIG. 33).

  The power supply unit 541 normally outputs an output of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the process at the time of a power failure even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain the value. Therefore, the main control device 261 and the payout control device 311 can normally execute and complete the power failure process.

When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal S2 to the main controller 261 and the payout controller 311. When the power of the pachinko machine 10 is turned on while the RAM erase switch 323 is pressed (including power-on due to power failure cancellation), the data in the respective RAMs 503 and 513 are cleared in the main controller 261 and the payout controller 311. The

  By the way, as shown in FIG. 24, the second symbol display device (liquid crystal display device) 42 has three symbol rows of left, middle, and right, and the upper symbol, the middle symbol, the lower symbol for each symbol row. Three symbols of each symbol (second symbol) are variably displayed. In the present embodiment, the series of symbols is composed of a main symbol with numbers “0” to “9” and a sub-pattern consisting of rhombus-shaped symbols, in ascending or descending order of the numbers. A main symbol is displayed, and a sub symbol is arranged between each main symbol to form a series of symbol rows. The main symbol and the sub symbol are variably displayed from top to bottom with periodicity.

  In such a case, in the left symbol row and the right symbol row, the series of symbols is displayed in descending order (that is, in order of increasing the number of the main symbols), and in the middle symbol row, the series of symbols is also in ascending order (that is, (In order of decreasing main symbol number). Then, the variable display stops in the order of left symbol row → right symbol row → middle symbol row, and at the time of the stop, five effective lines on the second symbol display device 42, that is, upper line L1, middle line L2, lower line L3, A special game video is displayed as a jackpot if the main symbol is aligned with a jackpot symbol combination (in this embodiment, the same main symbol combination) in either the right-up line L4 or the left-upline L5. Yes.

  Next, the operation of the pachinko machine 10 configured as described above will be described.

  In the present embodiment, the CPU 501 in the main control device 261 performs lottery (big hit lottery) of the second symbol display device 42, setting of symbol display, and the like using various counter information during the game. Specifically, 25, the jackpot random number counter C1 used for the jackpot lottery of the second symbol display device 42, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the second symbol display device 42, and the second Reach random number counter C3 used for reach lottery when the symbol display device 42 fluctuates and changes, random number initial value counter CINI used for initial value setting of the jackpot random number counter C1, and variation pattern selection of the second symbol display device 42 Fluctuation type counters CS1 and CS2 to be used, and left, middle and right outliers used for setting left out, middle and right outliers Counter CL, CM, has been with the use of the CR.

  Among these, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. Each counter is periodically updated, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. In addition, the RAM 503 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). Each value of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 is stored in time series in accordance with the winning history of the game balls.

  For details of each counter, the jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is a loop counter similar to the jackpot random number counter C1 (value = 0 to 676), and is updated once for each timer interruption and is repeatedly updated within the remaining time of normal processing. The jackpot random number counter C1 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the second start port 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “337,673”. Yes, the value of the random number that becomes a big hit at a high probability is 10, and the value is “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”. The high probability means a state where the jackpot is won by a predetermined probability variation pattern and the subsequent jackpot probability is increased as added value, that is, the time of so-called probability change, and the normal time (low probability) is such When not in a certain state.

  The jackpot symbol counter C2 determines a symbol when the fluctuation of the second symbol display device 42 is stopped at the time of a jackpot. In the present embodiment, the second symbol display device 42 has five effective lines. Since ten specific symbols (main symbols) are set, 50 counter values (0 to 49) are prepared. In other words, the jackpot symbol counter C2 is configured so that one by one is added in order within the range of 0 to 49, and after reaching the maximum value (that is, 49), it returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the second start port 33.

  Further, the reach random number counter C3 is configured to increment one by one within a range of 0 to 238, for example, and returns to 0 after reaching the maximum value (that is, 238). In this state, the reach random number counter C3 causes the last stop symbol to stop after the reach has occurred by shifting the last stop symbol by one before and after the reach symbol, and the last stop symbol after the reach has also occurred. “Reach other than front / rear off” that stops other than before and “completely out” that does not generate reach, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to reach other than front / rear detachment, and C3 = 22 to 238 corresponds to complete detachment. The reach lottery may be set individually according to the state of the lottery probability of the second symbol display device 42, the number of suspended balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in the present embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the second start port 33.

  In addition, one of the two variation type counters CS1 and CS2 is incremented by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. For example, the other variation type counter CS2 is incremented one by one within a range of 0 to 240, for example, and reaches the maximum value (that is, 240) and then returns to 0. In the following description, CS1 is also referred to as “first variation type counter”, and CS2 is also referred to as “second variation type counter”. The first variation type counter CS1 determines the reach type of the second symbol, such as so-called normal reach, super reach, premium reach, and other rough symbol variation modes, and the second variation type counter CS2 determines the final stop symbol ( In the present embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol.

  The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of CS1 and CS2 are acquired when the second symbol display device 42 determines the variation pattern at the start of variation of the second symbol.

  The left, middle, and right out symbol counters CL, CM, and CR are displayed in the left column second symbol, the middle column second symbol, and the right column second symbol when the big symbol lottery of the second symbol display device 42 is lost. This is for determining stop symbols (out-of-band symbols). Since each column displays either 20 main symbols or 20 secondary symbols, 20 (0 to 19) each. Counter values are provided. The left, upper, middle and lower symbols are determined by the out symbol counter CL, the upper, middle and lower symbols are determined by the out symbol counter CM, and the right symbol column is determined by the out symbol counter CR. The top, middle and bottom symbols are determined.

  In this embodiment, the value of each counter CL, CM, CR is updated at random by using the value of the built-in R register in the CPU 501. That is, when each outlier symbol counter CL, CM, CR is updated, the value of the lower 3 bits of the R register is added to the previous value, and when the addition result exceeds the maximum value, 20 is subtracted to determine the current value. The Each outlier symbol counter CL, CM, CR is updated in the normal process so that the update times do not overlap, and the combination of these outlier symbol counters CL, CM, CR is the reach other than the front / rear symbol buffer of the RAM 503, reach other than front / rear out It is stored in either the symbol buffer or the completely off symbol buffer. Then, when determining the variation pattern at the start of variation of the second symbol, the buffer value of any one of the front and rear outreach symbol buffer, the non-front and rear outreach symbol buffer, and the complete out symbol symbol buffer is acquired according to the value of the reach random number counter C3. The

  The size and range of each counter is only an example and can be arbitrarily changed. However, it is desirable that the big hit random number counter C1, the reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case.

  Although not shown, the first symbol random number counter C4 is used for the lottery of the first symbol display device 41. The first symbol random number counter C4 is configured as a loop counter that is incremented one by one within a range of, for example, 0 to 250 and returns to 0 after reaching the maximum value (that is, 250). The first symbol random number counter C4 is updated periodically (once every timer interruption in the present embodiment), and is acquired when the game ball passes through the first starting port 34 on either the left or right side. The number of random number values to be won is 149, and the range is “5 to 153”.

  Next, each control device executed by the CPU 501 in the main control device 261 will be described with reference to the flowcharts of FIGS. The processing of the CPU 501 is broadly divided into main processing that is started when the power is turned on, timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 msec), and power failure to the NMI terminal (non-maskable terminal). There is an NMI interrupt process activated by the input of a signal. For convenience of explanation, the timer interrupt process and the NMI interrupt process are described first, and then the main process is described.

  FIG. 31 is a flowchart showing the timer interrupt process. This process is executed by the CPU 501 of the main controller 261 every 2 msec, for example.

  In FIG. 31, first, in step S601, reading processing of various winning switches is executed. That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 261 is read, and the state of the switch is determined and the detection information (winning detection information) is stored.

  Thereafter, in step S602, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the random number initial value counter CINI update value is stored in the corresponding buffer area of the RAM 503. Alternatively, in the subsequent step S603, the big hit random number counter C1, the big hit symbol counter C2, and the reach random number counter C3 are updated. Specifically, the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are each incremented by 1 and their counter values reach the maximum values (in the present embodiment, 676, 49 and 238, respectively). Each time it is cleared to 0. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 503.

  Thereafter, in step S604, a start winning process associated with winning in the second starting port 33 is executed. The start winning process will be described with reference to the flowchart of FIG. 32. In step S701, whether or not the game ball has won the second start opening 33 is determined based on the detection information of the operation opening switch 224. If it is determined that the game ball has won the second start opening 33, in the subsequent step S702, whether or not the number N of the operation reserved balls of the second symbol display device 42 is less than the upper limit value (4 in the present embodiment). Is determined. The process proceeds to step S703 on the condition that there is a winning at the second start port 33 and the number N of actuated balls is <4, and the number N of actuated balls is incremented by one.

  In subsequent step S704, a random number related to the winning of the second symbol is acquired. Specifically, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 updated in step S603 are stored in the first area among the free storage areas of the reserved ball storage area of the RAM 503. Then, after the start winning process, the CPU 501 once ends the timer interrupt process.

  FIG. 33 is a flowchart showing the NMI interrupt process, and this process is executed by the CPU 501 of the main controller 261 when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 261 at the time of power-off is stored in the backup area 503a of the RAM 503.

  That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal S2 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 261. Then, the CPU 501 interrupts the control being executed and starts the NMI interrupt process of FIG. 33 is stored in the ROM 502 of the main controller 261. For a predetermined time after the power failure signal S1 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 261 can be executed, and the NMI interrupt processing is executed within the predetermined time.

  In the NMI interrupt processing of FIG. 33, first, in step S801, the used registers are saved in the backup area 503a of the RAM 503, and in the subsequent step S802, the value of the stack pointer is stored in the backup area 503a. Further, in step S803, the information on occurrence of power interruption is set in the backup area 503a, and in step S804, a power interruption notification command indicating that the power has been interrupted is transmitted to another control device.

  In step S805, a RAM determination value is calculated and stored in the backup area 503a. The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. In step S806, RAM access is prohibited. After that, an infinite loop is entered in preparation for the case where the power supply is completely shut down and processing cannot be executed.

  The NMI interrupt process is also executed in the payout control device 311 in the same manner, and the state of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513. Similarly, the power is supplied from the power supply unit 541 so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal S1 is output. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal S1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 in the payout control device 311 and the CPU 511 interrupts the control being executed. The NMI interrupt process of FIG. 33 is started. The contents are as described with reference to FIG. 33 (however, the transmission of the power-off notification command in step S804 is excluded).

  FIG. 26 is a flowchart showing an example of a main process executed by the CPU 501 in the main control device 261. This main process is started upon reset when the power is turned on.

  First, in step S101, an initial setting process associated with power-on is executed. Specifically, in order to set a predetermined value in the stack pointer and wait for the sub-side control devices (such as the sound lamp control device 262 and the payout control device 311) to become operable, for example, Wait processing is performed for about 1 second. In step S102, a payout permission command is transmitted to the payout control device 311. In subsequent step S103, RAM access is permitted.

  Thereafter, data backup processing is executed for the RAM 503 in the CPU 501. That is, in step S104, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed (ON). In subsequent step S105, the information on occurrence of power interruption is set in the backup area 503a of the RAM 503. It is determined whether or not. In step S106, a RAM determination value is calculated. In subsequent step S107, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the backup. The RAM determination value is a checksum value at a work area address of the RAM 503, for example. Note that it is possible to determine the effectiveness of backup based on whether or not the keywords written in a predetermined area of the RAM 503 are correctly stored.

  As described above, the pachinko machine 10 is turned on while pressing the RAM erase switch 323 when it is desired to return to the initial state when the power is turned on, for example, when the hall starts business. Therefore, if the RAM erase switch 323 is ON, the process proceeds to a RAM initialization process (step S114, etc.). Similarly, when the information on occurrence of power interruption is not set, or when a backup abnormality is confirmed by a RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 503 (step S114 or the like). That is, in step S114, the used area of the RAM 503 is cleared to 0, and in the subsequent step S115, initialization processing of the RAM 503 is executed. In step S116, interrupt permission is set, and the process proceeds to normal processing described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal. Execute the process (process when power is restored). That is, in step S108, the stack pointer before the power interruption is restored, and in step S109, the information on the occurrence of the power interruption is cleared. In step S110, a command for returning the sub-side control device to the gaming state at the time of power-off is transmitted, and in step S111, the used register is returned from the backup area 503a of the RAM 503. Further, in steps S112 and S113, the interrupt permission / non-permission is returned to the state before power-off, and then the address before power-off is returned.

  Next, the flow of normal processing will be described with reference to the flowchart of FIG. In this normal process, the main process of the game is executed. As an outline, the processing of steps S201 to S207 is executed as a periodic processing with a period of 4 msec, and the counter update processing of steps S209 and S210 is executed with the remaining time.

  In FIG. 27, first, in step S201, output data such as a command updated in the previous process is transmitted to each control device on the sub side. Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. Further, a stop symbol command, a variation pattern command, a confirmation command, etc. are transmitted to the display control device 45 when the second symbol display device 42 displays the variation of the second symbol. In addition, after the start of the second symbol variation, each time normal processing is performed in the order of variation pattern command-> left symbol sequence stop symbol command-> right symbol sequence stop symbol command-> middle symbol sequence stop symbol command. The command is sent once every 4 msec), and the confirmation command is sent when the fluctuation time elapses.

  Next, in step S202, the variation type counters CS1 and CS2 are updated. Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of the variation type counters CS1 and CS2 are stored in the corresponding buffer area of the RAM 503. In subsequent step S203, updating of each outlier symbol counter CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row is executed.

  The update process of each out symbol counter CL, CM, CR will be described in detail. As shown in FIG. 28, in step S301, it is determined whether or not it is time to update the out symbol counter CL in the left symbol row. In step S302, It is determined whether or not it is time to update the middle symbol row out of symbol counter CM. If the update timing of the left symbol sequence (YES in step S301), the process proceeds to step S303, and the outlier symbol counter CL of the left symbol sequence is updated. Further, if the update timing of the middle symbol row (YES in step S302), the process proceeds to step S304, and the out-of-middle symbol counter CM is updated. Further, if the update timing of the right symbol sequence (both NO in steps S301 and S302), the process proceeds to step S305, and the outlier symbol counter CR of the right symbol sequence is updated. In updating the outlier symbol counters CL, CM, CR in steps S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 20 is subtracted when the addition result exceeds the maximum value, The result of the calculation is out of sync and is used as the current value of the symbol counters CL, CM, CR.

  According to the CL, CM, and CR update processing, the left symbol row, middle symbol row, and right symbol row outlier symbol counters CL, CM, and CR are sequentially updated one by one in one normal process. The update times of the values do not overlap. As a result, every time the normal process is executed three times, one set of the off symbol counters CL, CM, CR is updated.

  Thereafter, in step S306, it is determined whether or not the combination of the updated outlier symbol counters CL, CM, CR is a combination of jackpot symbols. If the combination is a jackpot symbol combination, the processing of steps S307 to S312 is performed. Skip and end this process. On the other hand, if the combination of the off symbol counters CL, CM, and CR is not a jackpot symbol combination, the process proceeds to step S307.

  In step S307, it is determined whether or not the combination of the updated out symbol counters CL, CM, and CR is a reach symbol combination. It is determined whether or not. If the off symbol counters CL, CM, and CR are combinations of front and rear outreach, the process proceeds to step S309, and the combination of out symbol symbols CL, CM, and CR at that time is stored in the front and rear outreach symbol buffer of the RAM 503. If the out symbol counters CL, CM, CR are a combination of reach other than front / back off, the process proceeds to step S310, and the combination of the out symbol counters CL, CM, CR at that time is stored in the reach symbol buffer other than front / back out of RAM 503. .

  If the combination is other than the reach symbol, in step S311, it is determined whether or not the combination of the out symbol counters CL, CM, CR is a combination of out symbols, and if it is a combination of out symbols, In step S312, the combination of the off symbol counters CL, CM, and CR at that time is stored in the off symbol buffer of the RAM 503. When both of steps S307 and S311 are NO, the symbols are aligned on the left, middle, and right, that is, it corresponds to a jackpot state. In such a case, the off symbol counters CL, CM, and CR are stored in the buffer. The process is terminated without any processing.

  After the removal symbol counter update process, in step S204 in FIG. 27, the winning ball counting signal and the payout abnormality signal received from the payout control device 311 are read. Thereafter, in step S205, a second symbol variation process for performing variation display of the second symbol by the second symbol display device 42 is executed. By this second symbol variation process, jackpot determination, setting of a variation pattern of the second symbol, and the like are performed. However, details of the second symbol variation process will be described later.

  Thereafter, in step S206, a big prize opening / closing process for opening or closing the big prize opening of the variable prize winning device 35 in the case of the big win state is executed. That is, the big winning opening is opened for each round of the big hit state, and it is determined whether the maximum opening time of the big winning opening has passed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. At this time, the continuous winning opening is allowed on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  In step S207, display control of the first symbol by the first symbol display device 41 is executed. Briefly, on the condition that the game ball has passed through the first starting port 34, the first symbol random number counter C4 is acquired each time and the first symbol is displayed on the display unit 43 of the first symbol display device 41. Is displayed. Then, the first symbol lottery is carried out based on the value of the first symbol random number counter C4. When the first symbol hit state is reached, the second start port 33 is opened for a predetermined time. Although the description is omitted, the first symbol random number counter C4 is also updated by the timer interrupt process shown in FIG. 31, like the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3. .

  Thereafter, in step S208, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 msec in the present embodiment) has elapsed since the start of the previous normal process. Then, the random number initial value counter CINI and the variation type counters CS1 and CS2 are repeatedly updated within the remaining time until the next normal processing execution timing (steps S209 and S210). That is, in step S209, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503.

  In step S210, the update of the variation type counters CS1 and CS2 is executed (same as the previous step S202). Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of the variation type counters CS1 and CS2 are stored in the corresponding buffer area of the RAM 503.

  Here, since the execution time of each process of steps S201 to S207 changes according to the state of the game, the remaining time until the execution timing of the next normal process is not constant and varies. Therefore, the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) can be updated at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. .

  Next, the second symbol control process of step S205 will be described with reference to the flowchart of FIG.

  In FIG. 29, in step S401, it is determined whether or not it is currently a big hit. Note that the jackpot includes a special game displayed on the second symbol display device 42 and a predetermined time after the special game is ended. In a succeeding step S402, it is determined whether or not the second symbol display device 42 is displaying the variation of the second symbol. Then, when the big symbol is not being won and the variation of the second symbol is not being displayed, the process proceeds to step S403, and it is determined whether or not the number N of the operation reserved balls of the second symbol display device 42 is larger than zero. At this time, if the jackpot is being hit or if the number N of working suspension balls is 0, this processing is terminated as it is.

  Further, if it is neither a big hit nor a change display of the second symbol and if the number N of activated balls is> 0, the process proceeds to step S404. In step S404, 1 is subtracted from the number N of pending operation balls. In step S405, a process for shifting the data stored in the reserved ball storage area is executed. This data shift process is a process of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area.

  Thereafter, in step S406, a change start process is executed. Here, the details of the variation start processing will be described with reference to the flowchart of FIG. 30. In step S501, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1 stored in the execution area of the reserved ball storage area. To do. Specifically, whether or not the jackpot is determined based on the relationship between the jackpot random number counter value and the mode at that time, as described above, among the numerical values 0 to 676 of the jackpot random number counter C1 at the normal low probability, "337, “673” is a winning value, and “67, 131, 199, 269, 337, 401, 463, 523, 601, 661” is a winning value at high probability.

  If it is determined that the game is a jackpot, in step S502, a symbol corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, a table not showing the jackpot symbol (value of the jackpot symbol counter C2). And a symbol representing the correspondence between the symbol and the symbol), and the symbol is set as a stop symbol command. At this time, the numbers 0 to 49 of the jackpot symbol counter C2 correspond to any of the 50 jackpot symbols on all five active lines, and any one of the 50 jackpot symbols is set in the stop symbol command. Is done. When these jackpot symbols are gathered with a predetermined specific symbol, the process proceeds to a probable variation state, but when they are gathered with a non-specific symbol (non-specific symbol), the probabilistic state is not entered.

  Next, in step S503, the variation pattern at the time of the big hit is determined, and the variation pattern is set in the variation pattern command. At this time, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are checked, and the reach of the second symbol such as normal reach, super reach, premium reach, etc. based on the value of the first variation type counter CS1. The type and other rough symbol variation modes are determined, and the elapsed time until the final stop symbol (in this embodiment, the middle symbol) stops after the occurrence of reach based on the value of the second variation type counter CS2 (in other words, A more detailed symbol variation mode such as the number of variation symbols) is determined. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like. Needless to say, the symbol variation mode may be determined based on the value of only one of the first variation type counter CS1 and the second variation type counter CS2.

  On the other hand, if it is determined in step S501 that it is not a big hit, it is determined in step S504 whether or not a reach has occurred based on the value of the reach random number counter C3 stored in the execution area of the reserved ball storage area If the reach has occurred, it is further determined in step S505 whether the reach is out of front or back based on the value of the reach random number counter C3. In the present embodiment, the value of the reach random number counter C3 is any one of 0 to 238, of which “0, 1” corresponds to the out-of-front reach and “2-21” corresponds to the reach other than the back-and-forth out- “22 to 238” corresponds to no reach (complete detachment).

  If the front / rear out of reach has occurred, the process proceeds to step S506, and the left, middle, and right out of symbol counters CL, CM, CR stored in the front / rear out of reach symbol buffer of the RAM 503 are set as stop symbol commands. In step S507, a variation pattern at the time of front / rear out of reach is determined, and the variation pattern is set as a variation pattern command. At this time, as in step S503, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are checked, and the normal reach, super reach, and premium reach are determined based on the value of the first variation type counter CS1. Etc., until the reach stop type (in the present embodiment, the middle symbol) is stopped after the reach occurrence based on the value of the second variation type counter CS2 More detailed symbol variation modes such as the elapsed time (in other words, the number of variation symbols) are determined.

  If a reach other than front / rear out occurs, the process proceeds to step S508, and the left, middle, and right out-of-line counters CL, CM, CR stored in the reach symbol buffer other than front / rear out of RAM 503 are stopped. Set to. Also, in step S509, a fluctuation pattern at the time of reach other than front / rear deviation is determined, and the fluctuation pattern is set as a fluctuation pattern command. At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503, as in step S503 and the like.

  If it is neither big hit nor reach, the process proceeds to step S510, and the left, middle, and right out symbol counters CL, CM, and CR stored in the complete out symbol buffer of the RAM 503 are set as stop symbol commands. In step S511, the fluctuation pattern at the time of complete deviation is determined, and the fluctuation pattern is set in the fluctuation pattern command. At this time, since the reach does not occur, the player's interest is reduced, and various symbol variation modes are not required. Therefore, in the present embodiment, in step S511, the symbol variation mode is determined using only the first variation type counter CS1 (that is, without using the second variation type counter CS2). As described above, when the setting of the symbol stop command and the variation pattern command is completed at the time of jackpot, when the reach occurs, and when the reach does not occur, this processing ends.

  Returning to the description of FIG. 29, if step S402 is YES, that is, when the second symbol variation table is in progress, the process proceeds to step S407 to determine whether or not the variation time has elapsed. At this time, the variation time of the second symbol is determined according to the variation pattern of the second symbol, and when this variation time has elapsed, an affirmative determination is made in step S407. In step S408, the stop symbol set for stopping the change is set as a confirmation command, and then this process is terminated.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 34 is a flowchart showing the main process of the payout control device 311. This main process is started upon reset when the power is turned on.

  First, in step S901, an initial setting process associated with power-on is executed. Specifically, a predetermined value set in advance is set in the stack pointer, and an interrupt mode is set. In step S902, the process waits until a payout permission command transmitted from main controller 261 is received. When the payout permission command is received, the process proceeds to step S903 to permit the RAM access, and in step S904, the external interrupt pector is set.

  Thereafter, a data backup process is executed for the RAM 513 in the CPU 511. That is, in step S905, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed (ON). In subsequent step S906, the information on occurrence of power interruption is set in the backup area 513a of the RAM 513. It is determined whether or not. In step S907, a RAM determination value is calculated. In subsequent step S908, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the backup. The RAM determination value is, for example, a checksum value at a work area address in the RAM 513. It should be noted that it is possible to determine the effectiveness of backup based on whether or not the keywords written in a predetermined area of the RAM 513 are correctly stored.

  If the RAM erase switch 323 is ON, the process proceeds to a RAM initialization process (step S915, etc.). Similarly, when the occurrence information of power interruption is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 513 (step S915 or the like). That is, in step S915, the entire area of the RAM 513 is cleared to 0, and in the subsequent step S916, initialization processing of the RAM 513 is executed. In step S917, the CPU peripheral device is initialized, and in step S918, interrupt permission is set, and the process proceeds to a payout control process described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal. Execute the process (process when power is restored). That is, in step S909, the stack pointer before the power interruption is restored, and in step S910, the information on the occurrence of the power interruption is cleared. In step S911, CPU peripheral devices are initialized, and in step S912, the used registers are restored from the backup area 513a of the RAM 513. Further, in steps S913 and S914, the interruption permission / non-permission is returned to the state before the power interruption, and then the address before the power interruption is returned.

  Next, the flow of the payout control process will be described with reference to the flowchart of FIG.

  In FIG. 35, in step S1001, a command from the main control device 261 is acquired, and the total number of prize balls is stored. In step S1002, the launch control apparatus 312 is set for launch permission. In step S1003, the state return switch 321 is checked, and if it is determined that the state return operation has started, the state return operation is executed.

  Thereafter, in step S1004, setting of the lower pan full tank state or the lower pan full tank release state is executed in accordance with the change in the state of the lower pan 15. That is, when the lower pan 15 is detected based on the detection signal of the lower pan full switch, when the lower pan is full, the lower pan full state is set, and when the lower pan full is not reached , Set the lower pan full release state. In step S1005, setting of a tank ball absence state or a tank ball absence release state is executed in accordance with a change in the state of the tank ball. In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when there is no tank ball, the setting of the tank ball no state is executed. Cancel the setting.

  Thereafter, in step S1006, the presence / absence of a state to be notified is determined. If there is a state to be notified, the 7-segment LED provided in the payout control device 311 is notified.

  In steps S1007 to S1009, prize ball payout processing is executed. In this case, if the prize ball is not paid out and the total number of prize balls stored in step S1001 is not 0 (both NO in steps S1007 and S1008), the process proceeds to step S1009 and a prize ball control process (described later). FIG. 36) is started. Further, if the prize ball cannot be paid out or the total number of prize balls is 0 (YES in any of steps S1007 and S1008), the process proceeds to a lending payout process.

  Thereafter, in steps S1010 to S1012, a rental ball payout process is executed. In this case, if it is not possible to pay out the rent and if a rent-out request from the card unit has been received (NO in step S1010, YES in S1011), the process proceeds to step S1012 and a renting control process (described later). FIG. 37) is started. Further, if a rental ball cannot be paid out or a rental ball payout request has not been received (YES in step S1010 or NO in S1011), the subsequent ball removal process is executed.

  In step S1013, the state return switch 321 is checked to execute the ball removal process by driving the payout motor 358a on the condition that the ball removal disabled state is not set and the ball removal operation is not started. In the subsequent step S1014, the control of the vibrator 360 (vibrator control) is executed on condition that the ball is clogged. Thereafter, the process returns to the top of the payout control process.

  In the prize ball control process shown in FIG. 36, in step S1101, the payout motor 358a is driven to execute prize ball payout. In subsequent step S1102, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1103, where the payout motor 358a is driven to execute a retry process, and a stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

  If the rotation of the payout motor 358a is normal, the process proceeds to step S1104, and it is determined from the detection result of the payout count switch whether or not the game balls to be paid out as prize balls are normally counted. If the game ball count is not normal, the process proceeds to step S1105, where the payout motor 358a is driven to execute a retry process and the payout motor 358a is stopped, and then the process returns to the payout control process of FIG.

  Further, if the game ball count is normal, the process proceeds to step S1106, and it is determined whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout has been completed. If the payout has been completed, a stop process for the payout motor 358a is executed in step S1107, and then the process returns to the payout control process in FIG.

  In the ball lending control apparatus shown in FIG. 37, in step S1201, the payout motor 358a is driven to execute lending of a lending ball. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1203, the payout motor 358a is driven to execute a retry process, and a stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

  If the rotation of the payout motor 358a is normal, the process proceeds to step S1204, and it is determined from the detection result of the payout count switch whether or not the game balls to be paid out as rented balls are normally counted. If the count of the gaming machine is not normal, the process proceeds to step S1205, the payout motor 358a is driven to execute a retry process, and a stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

  If the game ball count is normal, the process proceeds to step S1206, where it is determined whether or not the game ball count by the payout count switch has reached a predetermined number of rented balls (25) and the payout is completed. If the payout has been completed, a stop process of the payout motor 358a is executed in step S1207, and then the process returns to the payout control process of FIG.

  Thus, in the pachinko machine 10 described above, in the key unit 27 in which the third hook member 279 and the fourth hook member 280 are removed from the locked portion 278 by unlocking the dedicated key, Even if the members 279 and 280 are improperly moved with a wire or the like, the lock mechanism 625 is actuated and the flange members 279 and 280 are prohibited from being displaced to the detachment side. As a result, the eaves members 279 and 280 continue to be locked to the locked portion 278 and the inner frame 12 is prevented from opening. Therefore, unauthorized unlocking by a wire or the like can be surely prevented, and safety can be improved. In particular, the lock mechanism 625 employs a structure that prevents the connecting rod 615 from moving in the unlocking direction, so that a mechanism that locks the third rod member 279 (first lock mechanism) and the fourth rod member 280 are provided. A locking mechanism (second locking mechanism) can be configured by a single locking mechanism 625. This also enables the connecting rod 615 to be directly connected to the third rod member 279 and the fourth rod member 280. For this reason, the configuration of the key unit 27 can be further simplified and the size can be reduced.

  In the pachinko machine 10 described above, the lock mechanism 625 includes the contact piece 627, and the first protrusion 633 and the second protrusion 634 formed on the connection rod 615 are brought into contact with the contact piece 627, thereby connecting the connection rod 627. The movement of 615 is blocked. The contact piece 627 is always urged toward the contact position. For this reason, it becomes possible to prevent the movement of the connecting rod 615 reliably. Further, when the key unlocking operation is performed, the contact piece 627 is rotated by the second protrusion 606, and the contact piece 627 is displaced to the non-contact position. For this reason, the locked state can be easily released according to the unlocking operation of the key. That is, even if the lock mechanism 625 is provided, the unlocking operation can be performed without impairing usability.

  In the pachinko machine 10 described above, when the inner frame 12 is opened, the contact piece 627 can be displaced from the contact position to the non-contact position side by a manual operation. For this reason, the locked state can be released without using a key. For example, when the key unit 27 is assembled in an assembly factory, the number of steps in the assembly work is reduced and the burden on the operator is reduced. be able to.

  In the pachinko machine 10 described above, the third hook member 279 and the fourth hook member 280 are held in a state of being displaced toward the release side by the release holding mechanism 640. For this reason, even if adjustment work is performed with both hands, the inner frame 12 can be closed without performing the unlocking operation again. Accordingly, the burden on the operator is reduced, and the hook members 279, 280 and the locked portion 278 do not collide when the inner frame 12 is closed, thereby preventing the hook members 279, 280 from being damaged. be able to. In particular, by engaging the locking rod 650 and the latching groove 646, the movement of the coupling rod 615 is restricted, and the locking rod 650 is constantly biased toward the engagement side by the third coil spring 648. Thus, it is possible to reliably hold the state displaced toward the separation side.

  On the other hand, when the inner frame 12 is closed, a release lever 651 for releasing the engagement between the locking rod 650 and the latching groove 646 is provided, and the connecting rod 615 is locked by the first coil spring 618. Since it is biased in the direction, when the inner frame 12 is closed, the connecting rod 615 can be moved accordingly and the third rod member 279 and the fourth rod member 280 can be displaced to the locking side. For this reason, it will be locked naturally and it can prevent forgetting to lock.

  Further, in the pachinko machine 10 described above, the key unit 27 is provided with the first hook member 273 and the second hook member 274 so as to prevent the front frame set 14 from being opened with respect to the inner frame 12. That is, the locking and unlocking of the inner frame 12 and the front frame set 14 can be individually operated by a set of key units 27. For this reason, usability can be further improved. In particular, the key-unlocking transmission mechanism 276 that transmits the operation of the cylinder lock 603 to the first hook member 273 and the second hook member 274 includes a first connecting rod 660, a second connecting rod 661, Since it is composed of the three connecting rods 662, even if one of the first rod members 273 and the second rod member 274 is illegally tilted, it is prevented from being transmitted to the other rod member. . That is, even if an unauthorized operation using a wire rod or the like is performed on one of the collar members, the front frame set 14 can be prevented from being opened by the other collar member.

  The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to these embodiments, and various improvements can be made without departing from the scope of the present invention as described below. And design changes are possible.

  That is, in the pachinko machine 10 of the above embodiment, the one provided with the two flange members 279 and 280 for locking the inner frame 12 with respect to the outer frame 11 is shown, but the number of the flange members is particularly limited. Instead, it may be one or three or more. Moreover, although what was detached | separated by tilting the eaves members 279 and 280 upward was shown, you may employ | adopt the structure which detach | leaves by tilting downward contrary to this, and by operation | movement other than tilting. You may comprise so that it may detach | leave and latch to a to-be-latched part.

  In the pachinko machine 10 of the above-described embodiment, the lock mechanism 625 has been shown to prevent the movement of the connecting rod 615, but is configured to directly prevent the displacement of the third rod member 279 and the fourth rod member 280. Also good. However, when the structure that prevents the movement of the connecting rod 615 as in this example is adopted, the lock mechanism 625 can be formed in the vicinity of the cylinder lock 603, and the lock is made according to the rotation of the cylinder lock 603. The lock release unit for releasing the state can be configured relatively easily.

  In the pachinko machine 10 of the above-described embodiment, as the detachment holding mechanism 640, the locking member 642 is pivotally supported on the connecting rod 615 and moved up and down together with the connecting rod 615, but is formed integrally with the frame body 600. The locking member 642 may be pivotally supported on the locked piece 645 and the locking rod 650 of the locking member 642 may be locked to the connecting rod 615. Even if comprised in this way, there can exist the same effect.

  In the pachinko machine 10 of the above embodiment, the lock mechanism 625 is provided only for locking the inner frame 12 with respect to the outer frame 11, and the front frame set 14 for the inner frame 12 is not provided with the lock mechanism 625 for locking. The locking mechanism 625 may also be provided for locking the front frame set 14. However, as described above, the front frame set 14 is fitted so as to enter the inside of the annular rib formed on the peripheral edge of the inner frame 12, and it is difficult to insert a wire or the like. Even if the lock mechanism 625 is not provided, safety can be ensured. In addition, by omitting the configuration corresponding to the lock mechanism 625 and the detachment holding mechanism 640, the number of parts of the key unit 27 can be reduced, and it can be manufactured at a relatively low cost.

  In the above embodiment, the unauthorized operation prevention cover 635 provided at a predetermined portion of the outer frame 11 is shown as an unauthorized operation prevention unit for preventing unauthorized operation on the contact piece 627. You may do it. Specifically, as shown in FIG. 49, if the size of the plate-like first convex portion 633 located behind the contact piece 627 is enlarged, the bending portion 628 of the contact piece 627 is changed. The rear is shielded by the first convex portion 633, and it is possible to prevent the wire from entering the bending portion 628. That is, in this case, the existing first convex portion 633 functions as an unauthorized operation preventing portion. If comprised in this way, it becomes possible to unitize an unauthorized operation prevention part as a part of key unit 27, and handling and an assembly | attachment become easy. In addition, even if the unauthorized operation prevention unit is provided as a part of the key unit 27, the inner frame 12 is shielded by only the direction in which the wire or the like may enter (that is, the rear). By opening the contact piece 627, the contact piece 627 can be directly operated.

  Further, in the above embodiment, the pachinko machine 10 is shown as a gaming machine, but the present invention can be applied to a gaming machine other than the pachinko machine, for example, a slot machine, an allapachi, an arrangement ball, or the like. That is, the present invention can be applied to any gaming machine that opens and closes an opening / closing member with respect to a base member.
