Description

  The present invention relates to a gaming machine that uses a game ball to play a game.

  As a prior art related to this type of gaming machine, a stage portion is formed on a decorative member arranged almost at the center of the gaming area, and a game ball is rolled on the inclined surface member of this stage portion, thereby making the game interesting. There is a prior art to add (see, for example, Patent Document 1). In this prior art, when a game ball flowing down the game area is received by the stage portion, the game ball rolls back and forth or left and right on the inclined surface member, and some of the game balls are directly below the center of the stage portion. It will fall towards the prize opening, and some will fall in the direction away from the prize opening. Since the stage part is provided on the game board surface at a position that is easily caught by the player, the player is interested in the movement of the game ball on the stage part, and the player can feel fun there.

  Furthermore, in the prior art, the inclined surface member is formed separately from the decorative member, and when the decorative member is removed from the game board, the inclined surface member can be separated from the decorative member. For this reason, if the existing inclined surface member is removed from the decorative member and replaced with an inclined surface member having a different inclination angle, it is considered that various game ball rolling modes can be obtained in the stage portion even with the same pachinko machine.

JP 2001-149546 A (page 2-3, FIG. 2, FIG. 3, FIG. 5)

  However, in the prior art, although the inclined surface member is separate from the decorative member, the mounting structure of the inclined surface member with respect to the decorative member is complicated, and thus there is a problem that work efficiency when attaching and detaching the inclined surface member is poor. is there.

  That is, the decorative member is roughly composed of an attachment substrate and a frame main body, and the inclined surface member is attached in a state of being sandwiched between the attachment substrate and the frame main body (Patent Document 1: Paragraph 0028). The mounting board and the frame main body are screwed to each other with the inclined surface member sandwiched between them. To remove this screw, all of the ball guide cover and the LCD display on the back side of the game board are used. It is necessary to remove the frame main body together with the mounting board from the game board (Patent Document 1: FIGS. 3 and 5). However, since two LED boards are mounted on the frame main body, and wiring to these LED boards is connected from the back side of the game board, when removing the frame main body together with the mounting board, the game board first It is necessary to pull out the wiring connected to the LED substrate on the back side.

  As described above, in the prior art, even when only the inclined surface member is attached / detached, the game board is removed from the frame body before that, or various members and wirings connected to the decorative member are removed on the back side of the game board. Because it is necessary, there is a lot of extra work and work efficiency is extremely poor.

  Then, this invention makes it a subject to provide the technique which can perform the attachment or detachment operation | work of the part used as object easily.

(Solution 1)
The gaming machine of the present invention has a game board in which a game area in which a game ball flows down is formed on the front side facing the player, and removably supports the game board and can be opened and closed on the front side of the game board. A frame body having a front door, and an opening window provided with a transparent plate that is formed on the front door and allows the game area to be seen through from the front side with the front door closed. A rolling part that rolls a game ball in the middle of flowing down the game area is arranged in the game area, and the game ball that has rolled in the rolling part is released from the rolling part and is again played by the game. In the gaming machine flowing down the area, the game board is formed by penetrating the game board in the front-rear direction, and is opened in the game area, and is arranged on the back side of the game board so as to be larger than the through hole. In this arrangement, from the front side through the through hole A rear unit that can be recognized, a ball guide member that is provided in the rear unit and that forms the rolling part in the through hole in a state where the rear unit is attached to the back side of the game board; and the game board A front unit attached to the front side of the game unit and disposed in the game area; a guide path formed in the front unit for guiding a game ball from the game area toward the rolling part; and the game A detachable space is formed in the through hole in a state where the front unit is removed from the board, and allows the ball guiding member to be attached to and detached from the rear unit from the front side of the game board.

  The detachable space and the front unit may have the following configurations. First, an attachment / detachment space is formed in the through hole of the game board, and the ball guiding member is attached / detached from the front side of the game board to the rear unit in a state where the rear unit is attached to the game board. Is acceptable. The front unit is detachably attached to the game board from the front side thereof, and closes the attach / detach space when attached to the game board, while being detached from the game board. It forms a space.

  In the gaming machine of the present invention, the game progresses while the launched game ball flows down the game area. Further, when the game ball is received by the rolling part in the process of flowing down, the game ball rolls variously there, so that the game is interesting by the rolling mode at that time. The game balls rolled at the rolling part are discharged from there and flow down the game area again, and win a winning opening below the rolling part or become an out ball without winning.

  In the gaming machine of the present invention, the front door is positioned on the front side of the game board supported by the frame. The front door guides the game balls flowing down the game area, and prevents interference from outside the game machine into the game area (the player's body touching or inserting foreign objects). For this reason, the front door is normally closed when the gaming machine is in use, but an opening window is formed in the front door, so that the gaming area can be viewed from the front side through the opening window.

  The rear unit is attached to the back side of the game board. The game board has a through hole, and is positioned so as to be visible from the front side through the through hole. Since the rear unit is disposed so as to extend over a range larger than the through hole, the rear unit has an outer shape that is larger than the opening area of the through hole. In this way, if the rear unit has a relatively large outer shape, there is an advantage that elements such as an operation mechanism, a movable body, and a display device for performing a stunning operation can be installed in the rear unit. .

  Further, since the ball guide member forming the rolling part is attached to the rear unit, the rolling part arranged in the game area is positioned in the through hole. When the game ball flowing down the game area is guided to the rolling part through the guide passage, the game ball is guided by the ball guide member to roll. Also, the game ball is released from the rolling part and flows down the game area again. At this time, if an element such as an operation mechanism or a display device for performing a rendering operation is provided in the rear unit as described above, the player can visually recognize the operation mechanism or the display device and then play a game ball at the rolling unit. Since the player's line of sight is also directed to the movement of the game, the game can be effectively excited by the rolling mode of the game ball at the rolling part.

  On the other hand, the gaming machine of the present invention adopts a configuration in which a detachable space is formed in the through hole of the game board, and the ball guide member is allowed to be detached from the front side through this detachable space. The detachable space may or may not be formed depending on how the front unit is attached to the game board. Normally, since the detachable space is not formed in the state where the front unit is attached to the game board, the ball guiding member cannot be detached in this state, and the inadvertent dropping is effectively restricted. On the other hand, when it is necessary to attach or detach the ball guiding member, a detachable space is formed by removing the front unit. In this state, the ball guiding member is allowed to be attached and detached. Can be replaced. The front unit can be attached and detached with the front door of the frame opened.

  As described above, according to the gaming machine of the present invention, since the ball guiding member can be detachably held in a normal use state, the ball guiding member may fall off the rear unit or be displaced due to an impact at the time of a game ball collision. There is no trouble in smooth progress of the game. On the other hand, when it becomes necessary to attach and detach the ball guiding member, the above-mentioned attaching / detaching space is formed simply by opening the front door of the frame and removing the front unit. The guide member can be easily attached and detached.

  In this regard, if priority is given to facilitating the attachment / detachment work, it is conceivable that the inclined surface member is detachably provided to the decorative member in the above-described prior art. However, simply configuring the inclined surface member to be detachable causes the following problems.

  That is, if the inclined surface member is structured to be detachable at any time with respect to the decorative member or the like, for example, when a game ball hits the inclined surface member (or the vicinity thereof) during use of the gaming machine, the inclined surface member is caused by the impact. There is a possibility that it may fall off, or the slanted surface member may be unlocked and displaced. In such a situation, there is a problem that the game can no longer be continued in a normal state, and the progress of the smooth game is hindered.

  Also, the fact that the inclined surface member is detachable at any time means that the inclined surface member can be easily removed simply by opening the front door of the gaming machine so that it can be directly touched by the inclined surface member. Become. For this reason, for example, when an employee opens the front door during a game hall opening time and removes a clogged ball on the game board surface, the inclined surface member may come off or be displaced only by touching the employee's hand. There is a risk of For this reason, employees must work carefully so as not to touch the inclined surface member as much as possible, and if they accidentally drop the inclined surface member, it must be restored one by one, There is a problem that the work is extremely complicated.

  On the other hand, in the structure of the present invention, even if the front door is opened, the ball guiding member cannot be attached / detached unless the front unit is removed, so that the above-described problems are not caused.

(Solution 2)
In the solution 1, the gaming machine of the present invention is formed on a part of the front unit and a fixing member that fixes the ball guide member to the rear unit, and the front unit is mounted on the game board. And a shielding area that shields the fixing member from being visible from the front side.

  In this case, since the ball guiding member is firmly fixed by the fixing member, it is possible to reliably prevent a situation where the ball guiding member is inadvertently dropped during normal use. Further, since the fixing member is not visible from the front side, the player is not aware of the presence of the fixing member, and is hardly aware that the ball guiding member itself is detachable. Therefore, from the player's point of view, a visual unity is generated in the components including the front unit, the ball guide member, and the rear unit, so that the appearance of the gaming machine as a whole is improved.

  In addition, since it is difficult to be aware that the ball guide member itself is detachable, even if there is a player who intends to cheat, the ball guide member is subjected to some modification (replacement with an illegal modified product, etc.) It does not lead to the idea to try and is effective in deterring fraud.

(Solution 3)
In solving means 1 and 2, the gaming machine of the present invention further comprises a winning opening provided at a position below the front unit in the gaming area and into which a gaming ball flowing down in the gaming area can flow. The ball guiding member includes a first guiding path that is guided in a manner in which a game ball that rolls on the rolling portion is sent out toward the winning opening, and a game ball that rolls on the rolling portion. And a second guide route that is sent to the gaming area below in a different manner from the first guide route.

  In the present solution, when the game ball is guided to the first guide route by the ball guide member, the probability of winning a winning prize opening is higher than when the game ball is guided to the second guide route. In this case, the guiding mode of the ball guiding member greatly affects the winning probability to the winning opening.

  In this way, when the ball guiding member guides the game ball, if the player's profit (winning probability at the winning opening) is greatly affected, the characteristics and performance of the ball guiding member remain as they are. Performance). For this reason, for example, in the performance evaluation performed in the development process of a gaming machine, the characteristics of the ball guiding member are those that greatly increase the player's profit (the game ball is guided in an extremely high winning probability manner). Etc.), the characteristics of the ball guide member need to be changed and replaced with another ball guide member to perform performance evaluation again.

  From this background, when the guidance mode of the ball guiding member greatly affects the winning probability at the winning opening, as a result of the performance evaluation in the development process of the gaming machine, the opportunity to change the characteristics of the ball guiding member and repeat the performance test However, even in this case, if the front unit is removed with the front door open, the above-mentioned attaching / detaching space is formed and the attaching / detaching work of the ball guiding member can be easily performed. Can greatly contribute to the reduction of

(Solution 4)
The gaming machine of the present invention also has the following configuration independently. That is, the gaming machine of the present invention has a game board in which a game area in which a game ball flows down is formed on the front side facing the player, and detachably supports the game board and opens and closes on the front side of the game board. A frame having a possible front door, and an opening window provided with a transparent plate that is formed on the front door and allows the game area to be seen through from the front side with the front door closed. A rolling part that rolls a game ball in the middle of flowing down the game area is disposed in the game area, and a game ball that has been rolled in the rolling part is released from the rolling part and is again In the gaming machine flowing down the game area, a through-hole formed through the game board in the front-rear direction, and attached to the game board from the back side, through the opening window and the through-hole from the front side It is arranged to be visible, A rear unit having a movable decorative body capable of performing a stunning operation in the through hole, and attached to the game board from the front side thereof, and arranged on the front side of the rear unit with the game board in between And a front unit that decorates the periphery of the through hole in the game area, a guide passage that is formed in the front unit and guides a game ball from the game area toward the rolling part, A prize opening disposed below the through hole in the game area, and a detachable attachment to the rear unit to form the rolling part, and a game guided from the gaming area to the rolling part A ball guiding member capable of guiding the ball according to a mode of rolling the ball along a predetermined path and discharging the rolled game ball toward the winning opening; and formed in the through hole, From the game board It is opened with the front unit removed, and this opening allows the ball guiding member to be attached and detached from the front side through the through hole, while the front unit is attached to the game board And a detachable space that makes the ball guiding member detachable by the closure.

  Due to the structure of the gaming machine of the present invention, the front door is positioned on the front side of the game board supported by the frame. Normally, the front door is closed when the gaming machine is in use, but an opening window is formed in the front door, so that the gaming area can be viewed from the front side through the opening window. The ball guiding member is attached to the rear unit, and the rear unit is attached to the game board from the back side. At this time, the rear unit is visible from the front side through a through hole formed in the game board, and when the game ball flowing down the game area is guided to the rolling part through the guide passage, the ball guide member then Guided to rolling. However, a front unit is attached to the front side of the game board, and the rear unit is positioned behind the front unit. For this reason, normally, the ball guiding member may be inadvertently dropped or misaligned during use of the gaming machine, or the ball guiding member may come off simply by touching the ball guiding member with some beat with the front door open. Never do.

  On the other hand, the gaming machine of the present invention adopts a configuration in which a detachable space is formed in the through hole of the game board, and the ball guide member is allowed to be detached from the front side through this detachable space. The detachable space is formed with the front unit removed from the game board, but when the front unit is attached to the game board, the detachable space is not formed, so the front unit is usually attached to the game board. In this state, the ball guiding member cannot be attached and detached, and its inadvertent dropping is effectively regulated. On the other hand, when it is necessary to attach or detach the ball guide member, the detachment space is formed by removing the front unit, and the ball guide member can be attached and detached in this state. Can be replaced. The front unit can be attached and detached with the front door of the frame opened.

  As described above, according to the gaming machine of the present invention, the ball guiding member can be held detachably in a normal use state, so that the smooth progress of the game is not hindered. On the other hand, when it becomes necessary to attach and detach the ball guiding member, the above-mentioned attaching / detaching space is formed simply by opening the front door of the frame and removing the front unit. The guide member can be easily attached and detached.

  In addition, the above-described ball guiding member adds an interest to the game by a mode of guiding the game ball, and sometimes plays a mode that greatly affects the player's profit (a mode in which the winning probability at the winning opening changes to high or low). Sphere can be guided.

  In this way, when the player's profits are affected by the manner in which the ball guiding member guides the game ball, the characteristics and performance of the ball guiding member are largely reflected in the performance of the gaming machine (playing ball performance) as it is. Become. For this reason, for example, in the performance evaluation performed in the development process of a gaming machine, the characteristics of the ball guiding member are those that greatly increase the player's profit (the game ball is guided in an extremely high winning probability manner). Etc.), the characteristics of the ball guide member need to be changed and replaced with another ball guide member to perform performance evaluation again.

  In this case, in order to replace only the ball guiding member with another one, if the game board is purposely removed from the frame body and the rear unit is further removed from the game board, the work efficiency is low and the work is extremely troublesome. Therefore, the gaming machine of the present invention employs a configuration in which a detachable space is formed in the through hole of the game board, and the ball guiding member is allowed to be detached from the front side through this detachable space.

  However, if the ball guiding member is normally allowed to be attached and detached at any time, the ball guiding member may be inadvertently dropped or displaced during use of the gaming machine, or the ball guiding member may be moved to any shape with the front door open. There is a possibility that the ball guiding member may come off just by touching the body.

  Therefore, in the gaming machine according to the present invention, the ball guide member is normally made non-detachable by making the structure in which the detachable space is not formed with the front unit attached to the game board, and the inadvertent dropping is effective. Is regulated. On the other hand, when it is necessary to attach or detach the ball guiding member, a detachable space is formed by removing the front unit, and the ball guiding member is allowed to be attached or detached in this state.

  As a result, it is possible to increase the work efficiency in the process of developing the gaming machine and greatly reduce the man-hours for developing the gaming machine. In addition, after the game machine is introduced as a product into the amusement hall, the situation where the ball guide member is inadvertently dropped is effectively avoided, so that a game machine having a structure that can sufficiently withstand long-term use is provided. Can do. In addition, since it is not necessary for maintenance staff to perform maintenance / inspection work with excessively cautious attention, the convenience of operating a gaming machine is increased.

(Solution 5)
In the solving means 1 to 4, the rear unit has a positioning member for positioning both the ball guiding member and the front unit with respect to the rear unit.

  Normally, the ball guide member is attached to the rear unit, and therefore, in the production process of the gaming machine, the ball guide member is attached together with the rear unit from the back side of the game board. However, the rear unit is provided with a positioning member that positions the ball guiding member with respect to the rear unit, assuming that the ball guiding member is attached and detached from the front side of the game board. On the other hand, the front unit is attached to the front side of the game board, but by positioning the front unit with respect to the rear unit, the front unit is appropriately arranged with respect to the game board. ing.

  In this case, the rear unit can be provided with a positioning member for each of the ball guiding member and the front unit. However, in this solution, the positioning member is provided with a function for positioning both of them separately. There is no need to provide a space for positioning the positioning member, and the space in the limited game area can be used effectively.

(Solution 6)
Alternatively, in the solving means 1 to 4, the gaming machine according to the present invention includes a first engagement piece formed on one of the front unit and the rear unit and a second engagement piece formed on the other side. And engaging the first engagement piece and the second engagement piece with each other with the front unit and the rear unit attached to the game board, respectively. A positioning mechanism that positions the front unit and the rear unit relative to each other; and the first and second engaging pieces formed on the ball guide member, with the ball guide member attached to the rear unit. And an engaging portion that positions the ball guiding member with respect to the rear unit by engaging with at least one of the rear unit.

  In this solution, an engagement piece is provided in each of the front unit and the rear unit, and when the front unit and the rear unit are attached to the game board, both engagement pieces are engaged with each other and the front unit and the rear unit are engaged. The rear unit and the rear unit can be positioned relative to each other. In this case, compared with the case where the front unit and the rear unit are each independently attached to the game board, both are positioned more accurately, so that the mounting accuracy between the front unit and the rear unit is increased, and these The visual unity between them can be enhanced.

  Further, since the engaging piece also has a function of positioning the ball guiding member, it is not necessary to provide another engaging piece only for the ball guiding member. For this reason, there is an advantage that the ball guiding member can be attached with a simple structure, and the ball guiding member can be arranged by effectively utilizing the space of the limited game area.

(Solution 7)
In the solving means 1 to 6, the gaming machine of the present invention is formed in the front unit and is capable of emitting light toward the front, and a rear surface of the front unit attached to the rear unit. And a light emitter that enables light emission in the light emitting region by emitting light forward from this position.

  In this case, a light emitting region is formed in the front unit, and the light emitter is provided not in the front unit but in the rear unit, although the light emitting operation is performed in this light emitting region. For this reason, the light emitters are irrelevant when attaching and detaching the front unit, and even if the wiring is connected to the light emitters or the light emitters are mounted on a mounting board or the like, the presence of them is not considered. The front unit can be attached and detached quickly and easily.

  The gaming machine of the present invention not only has a structure that is excellent in parts replacement convenience, but can also ensure stable operation over a long period of time.

  Hereinafter, embodiments in which the present invention is applied to a pachinko machine will be described with reference to the drawings.

(1. Configuration of pachinko machine)
FIG. 1 and FIG. 2 specifically show the configuration of the pachinko machine 1 according to an embodiment. The pachinko machine 1 includes a frame body and a game board 4, and the frame body includes an outer frame 2, a main body frame 3, a front frame 5, and the like. Among these, the outer frame 2 is configured by combining upper, lower, left and right wooden frame members in a rectangular shape, and a lower plate 6 for receiving the lower surface of the main body frame 3 is provided at the front lower portion thereof. The left side edge of the outer frame 2 is connected to the left end of the main body frame 3 via a hinge mechanism 7. As shown in FIG. 2, the main body frame 3 is located on the front side of the outer frame 2. Can be opened and closed. The main body frame 3 is configured by integrally molding the front frame body 8, the game board mounting frame 9, and the mechanism mounting frame 10 with a synthetic resin material. Among these, the front frame body 8 is formed on the front side of the main body frame 3, and its outer shape has a size that matches the outer shape of the outer frame 2 excluding the lower plate 6.

  The game board mounting frame 9 is formed integrally with the rear portion of the front frame body 8, and the game board 4 is mounted on the game board mounting frame 9 so as to be fitted from the front. The game board 4 can also be opened and closed from the main body frame 3 to the front side via the hinge mechanism 25, and the game board 4 can be attached to and detached from the main body frame 3 along with this opening and closing operation. A catch lock 9a (a so-called “snap lock”) is provided at the lower opening edge of the game board mounting frame 9 where the game board 4 is fitted. As shown in the drawing, when the catch lock 9a is tightened in a state where the game board 4 is fitted in the game board mounting frame 9, the game board 4 is fixed to the game board mounting frame 9 so as to be strongly pressed downward.

  Further, lock members 4 c are respectively attached to the upper right corner and the lower right corner of the game board 4. The lock member 4c has a plate shape elongated in the width direction of the game board 4, and the game board 4 is locked to the game board mounting frame 9 with its front end protruding rightward from the game board 4. It works as a nail. In other words, the lock member 4c has either a protruding position in which the tip portion protrudes laterally from the right end of the game board 4 or a retracted position retracted inward (center direction) from the right end of the game board 4. 4 is locked.

  On the other hand, although not shown in FIG. 2, locking holes are formed in the inner edge of the game board mounting frame 9 at positions corresponding to the upper and lower lock members 4c. For this reason, if the upper and lower lock members 4c are locked at the protruding positions in a state where the game board 4 is fitted in the game board mounting frame 9, the game board 4 is held in a state where the tip ends thereof enter the locking holes. Locks to the game board mounting frame 9 to prevent it from falling forward. Conversely, the game board 4 can be easily removed from the game board mounting frame 9 by releasing the upper and lower lock members 4 c from the protruding position and releasing the locking with the game board mounting frame 9.

  The board surface (front surface) of the game board 4 is provided with a guide rail 11 formed in an annular shape, and the guide rail 11 includes an outer rail and an inner rail. On the board surface of the game board 4, a substantially circular game area 12 is defined inside the guide rail 11. In addition, the structure (board | board surface structure) in the game area | region 12 is mentioned later.

  A bass speaker 14 is built in via a mounting plate 13 at the position of the lower left corner of the front frame 8. A launch rail 15 is provided at the position of the lower right corner of the front frame 8, and the launch rail 15 plays a role of guiding the game ball toward the launch path of the game board 4. A lower front member 16 is attached to the front frame 8 at a position below the launch rail 15 and the bass speaker 14. A lower pan 17 is formed at a substantially central position of the lower front member 16, and a firing handle 18 is provided at a right position thereof.

  As shown in part in FIG. 2, a locking device 19 is attached to the right side end of the main body frame 3 (front frame body 8) on the back side thereof. The locking device 19 has a function of locking the entire body frame 3 with respect to the outer frame 2 or locking the front frame 5 with respect to the body frame 3. The locking device 19 has two types of frame locking latches 21 and door locking latches 23, and one of the frame locking latches 21 corresponds to the closing tool 20 of the outer frame 2. For example, when the main body frame 3 is pushed into the outer frame 2 from the state shown in FIG. 2, the two frame locking latches 21 on the upper and lower sides respectively engage with the corresponding stoppers 20, thereby The outer frame 2 is fixed in a locked state.

  The other door locking latch 23 corresponds to the closing tool 22 provided on the rear surface of the front frame 5. For example, when the front frame 5 is pushed into the main body frame 3 from the state shown in FIG. At the top and bottom, the three door locking latches 23 are respectively engaged with the corresponding closing devices 22, whereby the front frame 5 is fixed in a locked state on the main body frame 3.

  The locking device 19 also has a cylinder lock 24. With the main body frame 3 and the front frame 5 closed, for example, an administrator / employee of the hall inserts a dedicated key into the key hole of the cylinder lock 24. When turned in one direction, the engagement between the frame locking latch 21 and the closing tool 20 of the outer frame 2 is released, and the main body frame 3 is unlocked. When the key is turned in the opposite direction, the engagement between the door locking latch 23 and the closing tool 22 of the front frame 5 is released, and the front frame 5 is unlocked. Since the front end of the cylinder lock 24 passes through the front frame 8 and the lower front member 16 and is exposed to the front surface of the lower front member 16, an unlocking operation is performed by inserting a key from the front of the pachinko machine 1. Can be easily performed.

  In the present embodiment, the main body frame 3 is unlocked with respect to the outer frame 2 by rotating the key in the clockwise direction (twisting operation), and the key is rotated in the counterclockwise direction (twisting operation). ), The front frame 5 is unlocked with respect to the main body frame 3. Thus, either the main body frame 3 or the front frame 5 can be unlocked only by changing the direction of the key turning operation. Further, when the main body frame 3 is locked in the closed state, the locking device 19 does not release the engagement between the frame locking latch 21 and the closing tool 20 of the outer frame 2 by an external operation using something other than the key. Thus, a lock mechanism for locking the displacement of the frame locking latch 21 is further provided.

  Thereby, when the main body frame 3 is locked in the closed state, the frame locking latch 21 is locked by the locking mechanism. The main body frame 3 (entire frame 8) has a rib projecting on the side closer to the gap between the outer frame 2 and the main body frame 3 (front frame 8) than the frame locking latch 21 (on the right side in FIG. 2). Even if a player who intends to cheat inserts a wire or the like through the gap between the outer frame 2 and the main body frame 3 (front frame 8) and directly operates the frame locking latch 21, the wire or the like Will abut the ribs and prevent further entry. Therefore, it is possible to suppress an act of illegally unlocking the main body frame 3 using a wire or the like from the gap between the outer frame 2 and the main body frame 3 (front frame 3).

  The front frame 5 is also called a glass frame or a glass door, and the front frame 5 is attached to the front side of the main body frame 3 through a hinge mechanism 25 so as to be opened and closed.

The upper speaker 29 and the lower speaker 14 also output a warning sound for notifying that an illegal act has been executed and an information sound for notifying that an error relating to a game has occurred.

  Due to the structure of the pachinko machine 1, the frame (outer frame 2, main body frame 3, front frame 5) is a part constituting the main body, and the board material of the game board 4, that is, the game board is detachably supported by the main body. It has become a part. The outer frame 2 plays a role of fixing the pachinko machine 1 to the island facility of the game hall (hall), and the main body frame 3 plays a role of detachably supporting the entire game board 4 including the game board. The game board is made of a strength member such as a plywood board, and various components (obstacles, accessories, winning devices, ornaments, electronic devices / control boards) are attached to the front and back of the game board.

(2. Board configuration)
FIG. 3 shows the game board 4 alone. As described above, the game board 4 is configured with the game board 4a molded in a rectangular shape as a strength member, and the game area 12 is formed in a circular shape on the front surface thereof. In the game area 12, a number of obstacle nails are driven in a predetermined arrangement, and a windmill 40 for guiding the ball is provided at an appropriate position. In the upper half of the game area 12, a remarkably large effect device 42 is arranged, and this effect device 42 has a design symbolizing the model of the pachinko machine 1, the game concept, and the like.

  The rendering device 42 has an elliptical outer shape that is flattened in the vertical direction, but has angular portions in some places. In particular, when viewed from the front, the top portion of the rendering device 42 protrudes in a mountain shape, and the upper edge portion extending left and right from the portion corresponding to the mountain top has a gentle downward slope. In addition, the left edge of the effect device 42 has a shape that is lumpy in the vertical direction, and thus has an outer shape in which the upper end and the lower end of the left edge are respectively squared. On the other hand, the right edge portion of the effect device 42 is curved in an arc shape along the outer edge of the game area 12, and the outline thereof is a smooth curve in contrast to the left edge portion. Further, the lower edge portion of the effect device 42 has a downward slope that is linearly narrowed toward the center, and is bent in the horizontal direction at the center position.

  A liquid crystal display device 50 is installed inside the effect device 42, and the liquid crystal display device 50 has a relatively large display screen. In addition, various decorative bodies 43a, 43b, and 43c and movable decorative bodies 44a, 44b, and 44c are arranged inside the rendering device 42 so as to surround the display screen of the liquid crystal display device 50, and the movable decorative body 44a. ˜44c, other decorative bodies 43d, 43e, and the like are arranged along the peripheral edge of the rendering device 42.

  In addition, fixed decorative bodies 45a, 45b, and 45c are installed at positions deeper than the movable decorative bodies 44a, 44b, and 44c when viewed from the front, respectively, and in areas around the fixed decorative bodies 45a, 45b, and 45c. Further, another decorative member 46 is installed. The decorative member 46 is laid so as to extend to both the left and right sides and the upper region of the liquid crystal display device 50. Therefore, when the rendering device 42 is viewed from the front side, the decorative member 46 is the decorative bodies 43a, 43b, 43c and movable decorative bodies 44a, 44b, and 44c are positioned as background areas.

  As described above, the rendering device 42 is visually provided with a design that symbolizes the game concept of the pachinko machine 1, and therefore, the individual decorative bodies 43a to 43e, the movable decorative bodies 44a to 44c, and the fixed decorative body 45a. ~ 45c, the decorative member 46 is uniquely shaped.

  An upper start port 52 is disposed in the game area 12 below the stage device 42, and a lower start port 54 integrated with the ball entry device 56 is disposed immediately below the game region 12. A pair of left and right opening / closing members 56a are attached to the ball entry device 56. When the opening / closing member 56a is displaced to the left and right as shown in FIG. On the contrary, when the opening / closing member 56a is displaced to the closed state, the game ball does not win the lower start port 54. The ball entrance device 56 is also designed to symbolize the game concept of the pachinko machine 1, as with the effect device 42.

  A pair of gates 58 are arranged at left and right positions of the ball entry device 56. Further, an attacker device 60 is disposed at a position below the ball entry device 56. The attacker device 60 has an opening / closing member 60 a for opening and closing the special winning opening 62. As shown in the figure, when the opening / closing member 60a is displaced so as to fall down toward the front side, the game ball flowing down from above is guided by the opening / closing member 60a and can enter the big prize opening 62, and conversely opens and closes. When the member 60a is displaced to a position along the board surface, the special winning opening 62 is closed and the game ball does not win.

  In addition, a pair of general winning ports 66 are arranged at left and right positions of the attacker device 60. In addition, a pair of left and right side decoration members 64 are arranged along the lower edge of the game area 12, and a general winning opening 66 is formed in each of the side decoration members 64. These side decoration members 64 also have a design that symbolizes the game concept of the pachinko machine 1, similar to the production device 42, and a visual sense of unity with the production device 42 is given to the modeling.

  In the side decoration member 64, various information is displayed as the game progresses, and the display of various information can be displayed by lighting / flashing of the LED incorporated in each side decoration member 64. . For this reason, for example, the right side decorative member 64 is formed with four light emitting regions 64a, each of which has a small circular shape, and four are arranged in a diamond shape. . Further, two light emitting regions 64b and 64c are formed above the light emitting region 64a, and each of the light emitting regions 64b and 64c has a bone of an animal (a rod shape like a femur and a bulge that becomes a joint at both ends). Designed in the shape of a certain thing). The left side decorative member 64 is also formed with a total of four light emitting areas 64d and 64e. These light emitting areas 64d and 64e are both small circles and are arranged so as to draw one row in the vertical direction. Hereinafter, the outline of the light emitting regions 64a to 64e will be described.

  First, four light emitting areas 64a arranged on the right side function as a special symbol display. The special symbol is for displaying to the outside that a special symbol lottery (a big hit lottery) has been performed in the pachinko machine 1 and that the winning result has been obtained. For example, if there is a prize for the upper start opening 52 or the lower start opening 54 in the normal game state (non-hit game) in the pachinko machine 1, the four light emitting areas 64a start blinking in various patterns. Then, the variation state of the special symbol is displayed. By such a change start of special symbols (so-called “start”), the player can recognize that the big hit lottery has been performed (or that the lottery result will come out from now on). Thereafter, when a certain amount of time has elapsed, the blinking operation of the light emitting area 64a is stopped, and the special symbol is stopped and displayed in such a manner that the lottery result (winning result) at that time is displayed. As for the special symbol stop display mode, in a simple example, if all the four light emitting areas 64a are lit, a win (big hit) is indicated, and if any one of the four light emitting areas 64a is extinguished, the selection is lost. The aspect which represents is mentioned (however, there exists an aspect other than these). Thereby, the player can visually recognize whether or not the big hit lottery is won. In the present embodiment, by using the liquid crystal display device 50 in addition to the four light emitting areas 64a, decorative designs (for example, designs of numbers “0” to “9”) are changed and stopped and displayed. Various effects related to the special symbol variation display and stop display can be performed.

  Further, four light emitting areas 48 are formed at the lower edge of the effect device 42 in relation to the special symbol display, and these four light emitting areas 48 function as a start memory lamp for special symbols. That is, the four light emitting areas 48 are individually designed in the form of numbers “1”, “2”, “3”, “4”, and the four light emitting areas 48 are “1” from left to right. "To" 4 "are arranged in order. These four light emitting areas 48 can represent the starting memory numbers (1 to 4) of special symbols by the light emission (lighting) modes of “1” to “4”.

  Specifically, if there is a winning at the upper start opening 52 or the lower start opening 54 during the game, the start condition of the special symbol is stored as a trigger, and if the special symbol is in a variable display in this state, The light emitting area 48 corresponding to “1” emits light (lights up), and it is displayed that the start memory number is 1. On the other hand, if the special condition does not fluctuate in the state where the start condition is stored (including the case where the stop state is changed from the fluctuating state), the special symbol fluctuating display starts based on the stored start condition. Is done. In this case, the storage of the start condition is erased, and the light emission of the light emitting area 48 corresponding to the start storage number “1” is stopped (turned off). In the present embodiment, since the upper limit of the start memory number is 4, when the upper limit is reached, no more start conditions are stored.

  Next, of the two light emitting areas 64b and 64c disposed above the light emitting area 64a, the light emitting area 64c located on the right side can function as a normal symbol display by lighting and blinking. The normal symbol is used to indicate that the normal symbol lottery is performed in the pachinko machine 1 and the result of the winning is obtained. For example, when a game ball passes through the gate 58 in the normal game state (non-hit game) in the pachinko machine 1, the light emitting area 64c starts to light up or blink in response to this, thereby displaying the normal symbol fluctuation state. Is done. On the other hand, the left light-emitting area 64b is turned on or off so that the internal game mode (a high probability game mode with a relatively high jackpot probability or a low probability game mode with a relatively low jackpot probability). ) Can be displayed.

  Of the four light emitting areas 64d and 64e that are arranged vertically on the left side decorative member 64, the lower two light emitting areas 64e are turned on and flashed to obtain the starting memory number (1 to 4) of normal symbols. Can be displayed. In addition, one of the upper two light emitting areas 64d is turned on when a big hit is made, so that the type of the big hit can be displayed. The jackpot type will be described later together with the configuration related to the control of the pachinko machine 1.

(3. Configuration of the production device)
FIG. 4 shows a specific manner of attaching the effect device 42 to the game board 4a. The production device 42 is roughly divided into two units divided forward and backward across the game board 4a. Specifically, the front unit 42a is located on the front side of the game board 4a, and the front unit 42a is attached to the game board 4a from the front side. Conversely, the rear unit 42b is located on the back side of the game board 4a, and the rear unit 42b is attached to the game board 4a from the back side. The liquid crystal display device 50 is attached to the rear unit 42b from the back side.

(3-1. Through hole)
The game board 4a is formed with a through hole 4b formed by penetrating the plywood material in the thickness direction (front-rear direction). The through hole 4b is greatly opened from the center of the game area 12 to a slightly higher range, and the shape of the opening substantially matches the outer shape of the front unit 42a.

(3-2. Mounting mode of the front unit)
The front unit 42a is formed in an annular shape so as to constitute the outer peripheral portion of the effect device 42. Therefore, the inner portion of the front unit 42a is in a state of being greatly opened. The front unit 42a is formed in a shape in which the rear part 42r facing the game board 4a is fitted into the through hole 4b when viewed in the front-rear direction, and the rear part 42r is formed in the through hole 4b. The front unit 42a is attached to the game board 4a while being fitted in the game board 4a. In the present embodiment, no parts (for example, solenoids, LEDs, boards, etc.) that perform electrical operations are attached to the front unit 4a. For this reason, when attaching the front unit 42a, since there is no need to connect any electrical wiring through the through hole 4b, the front unit 42a is not particularly concerned about the electrical connection relationship with other components, It can be detachably attached to the game board 4a alone.

  The front unit 42a is formed with a flange portion 42n so as to surround the outer periphery, and the flange portion 42n extends in parallel with the front surface of the game board 4a. Therefore, the front unit 42a can bring the flange portion 42n into close contact with the front surface (the decorative sheet surface) of the game board 4a in a state where the half portion 42r is fitted in the through hole 4b. The flange portion 42n is formed with a screw hole at an appropriate position. When the front unit 42a is attached to the game board 4a, the front unit 42a is screwed through the screw hole of the flange portion 42n. ing.

  Further, the front unit 42a is formed with an engagement piece (first or second engagement piece) 42s that protrudes rearward from the rear portion 42r. There are a total of three engagement pieces 42s, one on the upper edge of the front unit 42a and two on the lower edge (only one is shown in FIG. 4). When inserted from the front side of the game board 4a through the hole 4b, it protrudes further rearward from the back side of the game board 4a.

  On the other hand, in the state where the front unit 42a is attached to the game board 4a, the front half part 42f, the decorative bodies 43b, 43d, 43e, etc. are all located on the front side of the game board 4a. On the contrary, the two decorative bodies 43c positioned at the lower edge are positioned in the through hole 4b together with the rear half portion 42r. The front half part 42f of the front unit 42a and the decorative bodies 43b, 43d, 43e are set to have substantially the same thickness as the guide rail 11 and the panel decoration 4c, for example. For this reason, when the front unit 42a is attached to the game board 4a, the front half part 4f and the decorative bodies 43b, 43d, 43e project forward from the board surface within the game area 12, thereby guiding the flow of the game ball. -Also functions as a guiding member.

(3-3. Mounting mode of rear unit)
On the other hand, the rear unit 42b is attached to the back surface of the game board 4a without particularly forming a fitting relationship with the through hole 4b. Similarly, the rear unit 42b is screwed to the game board 4a through a screw hole of a flange portion (not shown in FIG. 4).

  Most of the rear unit 42b is located on the back side of the game board 4a in the mounted state. In particular, the fixed decorative bodies 45a, 45b, 45c and the decoration member 46 are slightly smaller than the back side of the game board 4a. Located behind. For this reason, when the player faces the game board 4, it is visually recognized that the fixed decorative bodies 45 a, 45 b, 45 c and the decorative member 46 are disposed at positions deeper from the through hole 4 b. You can feel the depth.

  However, the decorative unit 43a and the movable decorative bodies 44a, 44b, and 44c are attached to the rear unit 42b, and the decorative body 43a and the movable decorative bodies 44a, 44b, and 44c are both rear unit 42b (especially a decorative member). 46) to the front side. Therefore, when the rear unit 42b is attached to the game board 4a, the decorative body 43a and the movable decorative bodies 44a, 44b, 44c are in a state of entering the through hole 4b from the back side.

  The rear unit 42b is disposed over a wider area than the through hole 4b on the back surface of the game board 4a. That is, the rear unit 42b has an outer shape larger than the opening area of the through hole 4b, and only a part of the rear unit 42b is visible from the front side through the through hole 4b. For this reason, in the present embodiment, the rear unit 42b cannot be attached or detached by passing through the through hole 4b from the front side of the game board 4a.

(3-4. Positioning mechanism)
Furthermore, the rear unit 42b is formed with engagement holes 42h at three locations corresponding to the engagement pieces 42s of the front unit 42a (only the lower two locations are shown in FIG. 3). The joint hole 42h is formed in the engagement pieces (first or second engagement pieces) 68a, 68b and the like of the rear unit 42b. When the front unit 42a and the rear unit 42b are attached to the game board 4a from the front and rear, the three engagement pieces 42s reach the rear unit 42b through the through holes 4b and are respectively inserted into the corresponding engagement holes 42h. . Further, in this state, the individual engaging pieces 42s are engaged with the engaging holes 42h (engaging pieces 68a, 68b, etc.), whereby the front unit 42a and the rear unit 42b are positioned relative to each other. Note that the term “engagement” here does not indicate a restraining force in the front-rear direction, but a positional shift of the front unit 42a or the rear unit 42b in the up / down / left / right / oblique directions (directions along the board surface). It is a restraint.

  Ball guiding members 70 and 72 are arranged at the lower edge of the rendering device 42, that is, at a portion below the screen of the liquid crystal display device 50. The ball guiding members 70 and 72 can guide the game ball on the upper surface thereof and can give various changes in the rolling direction. As shown by a two-dot chain line in FIG. 4, the ball guide member 72 has a structure that can be separated to the front side together with the front unit 42a. The ball guide members 70 and 72 will be described in detail later.

FIG. 5 shows the rendering device 42 in a state of being disassembled into components. As already described, the production device 42 is roughly divided into a front unit 42a and a rear unit 42b, which are detachable from each other, but the rear unit 42b has two more spheres. The guide members 70 and 72 and the internal decoration body 74 are detachably attached.

  As shown in FIG. 5, the rear unit 42b is formed with a back wall 68 at a position below the display screen of the liquid crystal display device 50. The back wall 68 is formed by the rear unit 42b and the game board 4a. In the state attached to the board, it is positioned substantially parallel to the board surface. The back wall 68 expands so as to connect between the left and right edges of the rear unit 42b, and has a substantially inverted trapezoidal shape when viewed from the front.

(4-1. Engagement piece)
Engagement pieces 68a and 68b are respectively formed at both end portions of the back wall 68, and both of the engagement pieces 68a and 68b protrude from the back wall 68 toward the front side. The left and right engagement pieces 68a and 68b are formed in a flat cylindrical shape, and the left engagement piece 68a is flattened in the vertical direction when viewed from the front, and the right engagement piece 68b is flattened in the horizontal direction. ing. The engagement holes 42h are formed in the engagement pieces 68a and 68b, respectively. As shown in FIG. 5, an engagement piece 68s for forming a third engagement hole 42h is formed at the upper position of the rear unit 42b.

  A screw boss 68c is formed above the left and right engaging pieces 68a and 68b, respectively, and this boss 68c also protrudes to the front side (only the left boss 68c is shown in FIG. 5). It is shown). In addition, two bosses 68d are formed at the lower end portion of the back wall 68 at positions that are symmetrical from the center. These boss portions 68d also project from the back wall 68 to the front side. A screw through hole 68e is formed at a position above the two boss portions 68d.

  The ball guiding members 70 and 72 and the internal decoration body 74 are all detachable from the back wall 68 from the front side. When viewed from the state shown in FIG. 5, the inner decorative body 74 is first attached to the back wall 68, the back side ball guiding member 72 is attached from the front side, and finally the front side ball is attached. The guide member 70 is attached.

  Among these, a U-shaped cutout 74 a is formed at the lower edge of the internal decoration body 74, and when the internal decoration body 74 is in close contact with the back wall 68, the cutout 74 a is located on the lower side. Interference with the two bosses 68d can be avoided. Although not shown in FIG. 5, two screw holes are formed on the back side of the internal decorative body 74, and these screw holes correspond to the through holes 68 e of the back wall 68, respectively.

(4-2. Engagement part)
Engagement hole portions (engagement portions) 70a and 72a are formed at both ends of the rear and front ball guide members 70 and 72, respectively. These engagement holes 70a and 72a are formed so as to penetrate the ball guiding members 70 and 72 in the front-rear direction, and the opening shape thereof is slightly larger than the outer shape of the engagement pieces 68a and 68b. The ball guide members 70 and 72 are formed with screw holes at positions corresponding to the boss portions 68c and 68d, respectively. 5, screw holes 72b and 72c are shown only for the rear-side ball guiding member 72, but similar screw holes (reference numerals 70b and 70c are also distinguished for the front-side ball guiding member 70. ) Is formed.

(4-3. Attaching the internal decorative body)
When the inner decorative body 74 is pressed against the back wall 68 from the state shown in FIG. 5, the inner decorative body 74 is positioned between the engagement pieces 68a and 68b. In this state, the internal decoration body 74 is screwed through the two through holes 68e from the back side of the rear unit 42b. The thickness dimension in the front-rear direction of the internal decoration body 74 is set to be smaller than the protruding dimensions of the left and right engagement pieces 68a and 68b and the boss portions 68c and 68d. Therefore, in the state in which the internal decoration body 74 is first attached, the left and right engagement pieces 68a and 68b and the boss portions 68c and 68d are still projected to the front side.

(4-4. Attaching the back side ball guide member)

Therefore, normally, the attaching operation of the effect device 42 to the game board 4a is performed only for the rear unit 42b and the front unit 42a.

(5. Shielding area)
FIG. 6 shows a part of the left edge portion and the lower edge portion of the rendering device 42. When the front unit 42a and the rear unit 42b are attached to the game board 4a as described above, the front unit 42a is positioned on the front side of the rear unit 42b. At this time, the front unit 42a is in close contact with the front side of the screw holes 70b and 70c of the ball guide member 70 on the near side, and in this state, the screw holes 70b and 70c are shielded so that they cannot be seen from the front side. ing. In the present embodiment, the engaging pieces 68a and 68b are also shielded by the lower edge of the front unit 42a, so that all the configurations relating to the attachment and detachment and positioning of the ball guiding member 70 are visible from the front side. It is no longer being done. Note that the engaging piece 68s in the upper position is also shielded from the front side by the upper edge of the front unit 42a.

(6. Warp passage)
As shown in FIG. 6, a ball introduction port 76 that opens toward the side game area 12 is formed on the left side surface of the front unit 42a, that is, the left side surface of the decorative body 43b. In the front unit 42a, an upper warp passage 78a extending from the ball introduction port 76 to the inside is formed. The upper warp passage 78a is gently inclined downward from the sphere introduction port 76 to the lower right, and then is bent from the center of the decorative body 43b to the back and gently inclined downward.

  Thereafter, the upper warp passage 78a ends at the rear end position of the front unit 42a, and is connected to the lower warp passage 78b at a rear position from there. The lower warp passage 78b is formed so as to extend inside the left side edge of the rear unit, and when the lower warp passage 78b comes into contact with the innermost portion continuing from the upper warp passage 78a, the lower warp passage 78b It goes down all at once, bending down. The lower warp passage 78b bends to the right at the lower end position of the left edge of the rear unit 42b and is opened to the right at the end position. A warp outlet 78c is formed at the end of the lower warp passage 78b, and the warp outlet 78c communicates with the upper surface of the ball guiding member 72 on the back side.

  Therefore, when a game ball flowing down the game area 12 jumps into the ball introduction port 76, it is guided to the inside of the effect device 42 through the upper warp passage 78a and the lower warp passage 78b, and guided to the back side from the warp outlet 78c. Released onto member 72.

  Thereafter, the game ball rolls so as to sequentially transfer from the back-side ball guide member 72 to the front-side ball guide member 70, and finally from the ball guide member 70 via the lower edge of the front unit 42a. It spills downward or enters the discharge passage 72d and is discharged directly from the lower discharge port 72e. At this time, the game ball released from the discharge port 72e passes directly between the two obstacle nails (life nails) arranged immediately below it, and wins the upper start port 52 with a relatively high probability. Can do. On the other hand, most of the game balls that spill through the upper edge of the front unit 42a are bounced back by the obstacle nail and the direction of the fall changes randomly, so that only a relatively low probability wins the upper start opening 52. No longer. Hereinafter, the manner of guiding the game ball by the ball guiding members 70 and 72 will be described.

(8. Guiding mode by ball guiding member)
7 to 9 show the manner of guiding the game ball by the ball guiding members 70 and 72 and the manner of releasing the game ball from the front unit 42a. As described above, the game balls guided through the upper warp passage 78a and the lower warp passage 78b are delivered from the warp outlet 78c onto the ball guiding member 72 on the back side. An upper stage 80 is formed on the far side ball guiding member 72 at the farthest position (close to the screen of the liquid crystal display device 50) when viewed from the front, and an intermediate stage 82 is formed on the front side of the upper stage 80. ing.

  Of these, the upper stage 80 has a valley shape with a lower center, but the middle stage 82 has a mountain shape with a higher center. In addition, a recess 80 a that is inclined toward the front side is formed at the center position of the upper stage 80. Therefore, the game ball decelerates while rolling left and right on the upper stage 80, eventually enters the central recess 80a, and moves from here to the middle stage 82. At this time, some of the game balls that have entered the central depression 80a do not move immediately onto the middle stage 82, but roll in such a manner that they slightly swing in the left-right direction within the depression 80a. .

  When the game ball moves onto the middle stage 82, the rolling direction is assigned to either the left or right, and the game ball rolls along the inclination as it is. At both end portions of the middle stage 82, the side wall 82a is shaped to bend toward the near side as it approaches the both end portions. For this reason, when the game ball approaches the both side ends of the middle stage 82, it is guided to the near side along the curved side wall 82a, and spills onto the ball guide member 70 on the near side as it is.

  A lower stage 84 is formed on the upper surface of the sphere guide member 70 on the near side, and guide walls 84 a that are continuous with the side wall 82 a of the middle stage 82 are formed on both ends thereof. These guide walls 84a are curved and formed so as to go from both sides of the lower stage 84 to the front side, opposite to the side walls 82a. Therefore, the game ball guided to the side wall 82a of the middle stage 82 and spilled to the near side as described above is guided to make a U-turn along the guide wall 84a.

  The lower stage 84 is shaped such that the upper surface is wavy, and the central portion is slightly raised, and the left and right portions are recessed from the central portion so as to draw a gentle curve. In addition, the central portion and the left and right portions thereof are formed with recessed portions 84b and 84c, respectively, and the recessed portion 84b in the central portion has a downward slope toward the back side, and the recessed portions on the left and right portions thereof. On the contrary, the portion 84c has a downward slope toward the near side.

  As shown in FIG. 9, the discharge passage 72 d descends behind the lower stage 84 and is bent forward from a position below the lower stage 84 to be gently inclined. The discharge passage 72d leads to the inside of the front unit 42a, and opens to the front side at the discharge port 72e.

  Accordingly, among the game balls rolling on the lower stage 84, the left and right portions of the game ball pass through the hollow portion 84c and reach the central hollow portion 84b, and the discharge passage from the hollow portion 84b (first guide path). Since the game ball that has entered 72d is released directly downward from the discharge port 72e as described above, it is guided in such a manner that it wins the upper start port 52 with a relatively high probability (FIGS. 7 and 9).

  On the other hand, the left and right recesses 84c (second guide path) are guide paths for sending the game ball from the lower stage 84 to the lower edge of the front unit 42a. For this reason, among the game balls rolling on the lower stage 84, there was no momentum to reach the central portion, or there was momentum to reach the central portion, but either left or right after passing through the depression 84b The game balls that have fallen enter the hollow portions 84c on the left and right portions, and spill out from here. Note that some of the game balls that have entered the recess 84c roll so as to slightly swing left and right here. In any case, the game ball that has entered the recess 84c is eventually guided to the near side along the inclination and is sent to the lower game area 12 through the upper surface of the lower edge of the front unit 42a. It will be.

  The lower edge portion of the front unit 42a is formed in a valley shape having a lower central portion. Further, this central portion (portion above the discharge port 72e) is slightly inclined toward the front side, and further has a width that allows the game ball to roll in the left-right direction. Therefore, the game balls that have moved from the recess 84c of the lower stage 84 to the lower edge of the front unit 42a are collected at the center, where they change position while rolling in the left-right direction, and eventually downward. Spill down. In this case, since the game ball falls from various positions when viewed in the left-right direction, the game ball is guided in such a manner as to win the upper start opening 52 only with a relatively low probability (FIGS. 8 and 9).

(9. Performance evaluation of ball guide member)
The above is the two stages of guidance by the lower stage 84, that is, the front-side ball guiding member 70, but the proportion of the game balls guided in the form of passing through the discharge passage 72d depends on the curved shape and the depression of the lower stage 84. It varies depending on the surface shapes of 84b and 84c. For example, if the depression 84b in the central portion is extremely greatly depressed from the upper surface of the lower stage 84 in the surrounding area, the game ball easily enters the depression 84b, and as a result, the game ball passes through the discharge passage 72d. The ratio induced by is relatively high. On the other hand, if the depression 84b in the central portion is not so depressed as compared with the upper surface of the lower stage 84 in the vicinity, the game ball is less likely to enter the depression 84b, and as a result, the game ball is released into the discharge passage 72d. The ratio induced in the mode passing through is relatively low (other various factors are conceivable, but are omitted here).

  The ratio at which the game balls are guided in the manner of passing through the discharge passage 72d as described above is related to the performance evaluation of the ball guide member 70 performed in the development process of the pachinko machine 1. That is, in the development process of the pachinko machine 1, a performance test is performed on the pachinko machine 1 produced in the prototype stage by trial shooting of a game ball, in which the performance of the ball guiding member 70 (the ratio of guidance to the discharge passage 72d) ) Is verified. As a result of the performance evaluation, if it is necessary to review the work, a specific shape of the ball guiding member 70 is changed, a test shot is performed again, and the performance evaluation is repeated on a daily basis. Alternatively, performance evaluation is also performed in which a plurality of ball guiding members 70 having different curved surface shapes are sequentially changed one by one and tested, and individual ball guiding performances are compared and examined. In this performance evaluation, the present embodiment adopts an advantageous structure related to the attaching / detaching operation of the ball guiding member 70, and the specific contents thereof will be described below.

(10. Detachable space)
FIG. 10 specifically shows how the ball guide member 70 is attached and detached after the pachinko machine 1 is assembled. Here, “after assembly” refers to a state in which the pachinko machine 1 can be operated, that is, after being assembled into a state in which a game ball can be launched to play a game, a prize ball can be paid out, or a production operation can be performed. means. Accordingly, here, the front unit 42a and the rear unit 42b are already attached to the game board 4a, and the game board 4 is attached to the game board mounting frame 9 with all necessary components attached. Has been.

  As shown in FIG. 10, even after the pachinko machine 1 is assembled, it is possible to remove only the front unit 42a of the effect device 42 from the game board 4a by opening the front frame 5 thereof. Is possible. That is, since the front unit 42a is screwed to the game board 4a through the flange portion 42n at a plurality of locations, if the screws are loosened and removed, the front unit 42a is pulled to the near side. This can be easily detached from the game board 4a. In FIG. 10, even the main body frame 3 is shown as being opened from the outer frame 2 to the front side, but it is not essential here to open the main body frame 3. Therefore, in the following description, it is assumed that only the front frame 5 is open.

  When the front unit 42a is removed, the through hole 4b into which the front unit 42a has been fitted is exposed to the front side. At this time, the detachable space 86 of the ball guiding member 70 is formed (opened) in the lower portion of the through hole 4b. The attaching / detaching space 86 is positioned as a work path / space for attaching / detaching the front ball guiding member 70 to / from the rear unit 42b from the front side of the game board 4a. It is defined as a path / space having a projected area almost the same as or larger than the external dimension.

  Therefore, when the front unit 42a is attached to the game board 4a in a normal completed state, a part of the front side of the ball guide member 70 (a part including the engagement pieces 68a and 68b and the screw holes 70b and 70c) Since it is shielded by the lower edge portion of the front unit 42a, the detachable space 86 is not formed (closed) in this state.

  On the other hand, as shown in FIG. 10, when the front unit 42a is further removed from the game board 4a with the front frame 5 opened, the detachable space 86 is formed (opened). In this state, the developer / designer of the pachinko machine 1 can perform an operation of removing the existing ball guiding member 70 and replacing it with another newly prepared ball guiding member 70. At this time, the developer / designer can release the fastening at the two locations by first pushing the tool to the head of the screw exposed to the front surface through the attachment / detachment space 86, and turning the tool as it is to loosen the screw. When the developer / designer pulls the ball guiding member 70 toward the front side through the attachment / detachment space 86, the engagement hole portion 70a and the engagement pieces 68a, 68b of the rear unit 42b are disengaged. Only the ball guiding member 70 can be removed. At this time, the fastening of the back-side ball guiding member 72 is also released together, but the back-side ball guiding member 72 is in a state in which the engaging hole portion 72a is fitted to the engaging pieces 68a and 68b. Therefore, the back-side ball guiding member 72 is not dropped together with the front-side ball guiding member 70.

  When the existing ball guiding member 70 is removed as described above, the rear ball guiding member 72 remains in the rear unit 42b. Next, the designer / developer positions another ball guide member 70 prepared as a replacement in the attachment / detachment space 86, and the left and right engagement hole portions 70a are engaged with the engagement pieces 68a and 68b of the rear unit 42b. The ball guiding member 70 is pushed in so as to fit. If the engagement hole portions 70a and 70b are accurately fitted to the engagement pieces 68a and 68b, the ball guide member 70 is accurately inserted into the rear unit 42b simply by pushing the ball guide member 70 as it is. Positioned. Accordingly, the front-side ball guide member 70 is positioned so as to be superimposed on the back-side ball guide member 72. Then, the developer / designer screws the ball guiding members 70 and 72 together through the attachment / detachment space 86 to complete the attachment to the rear unit 42b.

  When the replacement of the ball guiding member 70 is completed in this way, the developer / designer simply attaches the front unit 42a to the game board 4a from the state shown in FIG. 10 and then closes the front frame 5 only. Thus, a performance test can be performed by a test shot of the pachinko machine 1.

(11. Summary of Embodiment)
As described above, the pachinko machine 1 according to the embodiment has the following remarkable utility.

  (1) Even after the pachinko machine 1 is assembled, it is possible to relatively easily replace the ball guiding member 70 as necessary. In this case, it is only necessary to open the front frame 5 and remove the front unit 42a of the effect device 42, so that the game board 4 is removed from the game board mounting frame 9 one by one, and the control board box and the rear unit 42b on the rear side are further removed. There is no need to remove the game board 4a from the game board 4a. In particular, in the present embodiment, the outer shape of the rear unit 42b is larger than the opening area of the through hole 4b, and the rear unit 42b itself cannot be detached from the front side of the game board 4a. The ball guide member 70 can be attached and detached through the through hole.

  (2) In the development process of the pachinko machine 1, the ball guide member 70 is frequently replaced and performance evaluation is performed per work day. In this embodiment, such performance evaluation is performed. Even when trial and error are repeated while changing the specific shape of the ball guide member 70 according to the result, the man-hours for development of the pachinko machine 1 are greatly reduced by greatly improving workability. be able to.

  (3) As described above, the front unit 42a has a light emitting area 48 for displaying the number of start memories stored in a special symbol. Not equipped at all. Therefore, when replacing the ball guiding member 70, it is not necessary to repeat the electrical wiring operation every time the front unit 42a is attached / detached. Therefore, the replacing operation of the ball guiding member 70 can be performed quickly and easily. it can.

  (4) On the other hand, normally, in the assembled state of the pachinko machine 1, since the detachable space 86 is not formed (closed) by the front unit 42a, the ball guiding member 70 is inadvertently dropped. There is nothing. Therefore, since it can sufficiently withstand long-term performance tests and actual operation in an amusement hall, it can greatly contribute to the reliability, durability, quality improvement, etc. of the pachinko machine 1.

  (5) In addition, since the fixing member (fastener) such as a screw for fixing the ball guiding member 70 is not visible from the front side in the attached state of the front unit 42a, the ball guiding member 70 can be detached from the player. It is not conscious that it is. For this reason, even if there is an unauthorized player who intends to make some modification to the structure of the pachinko machine 1, another illegally modified part of the ball guiding member 70 (extremely remodeled with a high percentage of winning in the upper starting opening 52). ), And the effect of preventing fraudulent acts can be achieved.

  (6) In one embodiment, since the fixing member (fastener) such as a screw for fixing the ball guiding member 70 is covered with the decorative body 43c of the front unit 42a, the appearance of the rendering device 42 is impaired. There is no.

(12. Control of pachinko machine)
FIG. 11 schematically shows a configuration for controlling the operation of the pachinko machine 1. The control of the pachinko machine 1 is roughly divided into a main board group and a peripheral board group, and among these, the main board group plays game operations (winning detection, winning judgment, special symbol display, prize ball payout, etc.) ), And a group of peripheral boards controls production operations (light emission decoration, sound output, liquid crystal display, etc.). All of these boards are installed on the back side of the pachinko machine 1 and are normally visible or operated from the front side unless the main body frame 3 is opened after unlocking the main body frame 3. There is no. In addition to this, the pachinko machine 1 is equipped with a power supply board, a launch control board, an interface board (in the case of a CR machine), and the like. Is omitted.

(12-1. Main board group)
The main board group includes a main board 101 and a payout board 105. The main board 101 includes a CPU 102 as a central processing unit, a ROM 103 as a read-only memory, a RAM 104 as a readable / writable memory, and the like. Among these, the CPU 102 executes a game control program stored in the ROM 103 and controls various games performed in the pachinko machine 1 in accordance with the execution. In addition, the CPU 102 creates commands (effect command, payout command, etc.) to be transmitted to the peripheral board group and the payout board 105. The RAM 104 temporarily stores information such as various data generated in various processes executed on the main board 101 and input signals.

  The main board 101 is connected to a gate switch 174a, start port switches 170a and 170b, a count switch 175a, a general prize opening switch 113a, and the like. Detection signals are input to the main board 101 from these switches. The Specifically, the gate switch 174a is installed corresponding to the gate 58 in the game area 12, and when the game ball passes through the gate 58 in the process of flowing down, the passage is detected by the gate switch 174a, and is detected. A signal is input to the main board 101. The start port switch 170a is installed corresponding to the upper start port 52, and the start port switch 170b is installed corresponding to the lower start port 54. Therefore, when a game ball wins the upper start port 52 or the lower start port 54, a detection signal is input to the main board 101 from the corresponding start port switches 170a and 170b. The count switch 175a is installed in correspondence with the big winning opening 62. When a game ball wins the big winning opening 62 during the big hit game, a detection signal is inputted from the count switch 175a to the main board 101. The general winning opening switch 113a is arranged corresponding to the general winning opening 66, and when a game ball wins the general winning opening 66, a detection signal is input from the general winning opening switch 113a to the main board 101.

  And CPU102 performs the process according to these input detection signals. That is, the CPU 102 determines the solenoids 171a and 176a, the special symbol display 141, the normal symbol display 144, the special symbol start memory lamp 147 (light emitter), the universal diagram start memory LED 148, the status display LED 145 based on the input detection signal. Each drive signal is output to the big hit type display LED 146 and the like. Further, the CPU 102 outputs a payout command for instructing payout of the game ball according to the winning to the payout board 105.

  The special figure start memory lamp 147 is a light emitter (LED) for emitting light from the light emitting area 48a of the front unit 42a. The special figure start memory lamp 147 is attached to the rear unit 42b together with the substrate. ing. For this reason, in this embodiment, the electrical wiring and the boards of the special figure start memory lamp 147 are not attached to the front unit 42a at all.

  The payout board 105 also includes a payout CPU 106 as a central processing unit, a payout ROM 107 as a read-only memory, a payout RAM 108 as a readable / writable memory, and the like. When a winning of a game ball is detected by the above-described start port switches 170a, 170b, count switch 175a, general winning port switch 113a, etc., a detection signal is input to the main board 101 from each switch. In the main board 101, a payout command for instructing the payout board 105 to pay out a specified number of game balls is transmitted from the CPU 102 based on the input detection signal. Then, the payout board 105 processes the payout command received from the main board 101, and outputs a drive signal to the payout device 109 (payout motor) to execute payout of a specified number of game balls. As a result, the specified number of game balls are actually paid out by the payout device 109.

  Further, a launch device 135 having a launch motor is connected to the payout board 105, and the launch device 135 can perform an operation of launching a game ball toward the game area 12 using the power of the launch motor. . When the player operates the operation handle 18 (twisting operation), the firing motor of the launching device 135 is driven, and thereby a game ball is launched.

  Although not shown in FIG. 11, the launching device 135 incorporates a touch sensor for detecting that the player's body is touching the operation handle 18. The launching device 135 is in a state where the firing motor can be driven when it is detected that the player is touching the operation handle 18. In this state, when the operation handle 18 is twisted clockwise from the initial position, the launching device 135 actually drives the firing motor to launch the game ball.

  Alternatively, a lower plate full tank switch is provided for detecting that the lower plate 17 is full, that is, the lower plate 17 is filled with paid out game balls, and a detection signal from the lower plate full tank switch is input. When the operation is performed, the operation of the operation handle 18 is controlled to be unacceptable, and thereby the driving of the firing motor by the launching device 135 can be made impossible. That is, the game balls paid out from the payout device 109 are temporarily stored in the upper plate 28. However, when a number of game balls that cannot be stored in the upper plate 28 are paid out, the game balls cannot be stored. Are stored in the lower plate 17 communicating with the upper plate 28. In this state, the game ball is further paid out by the payout device 109, and when the lower plate 17 is finally full, a detection signal is output from the lower plate full tank switch, so that the operation of the operation handle 18 is accepted. Controlled to an impossible state. Further, in this case, when the detection signal from the lower pan full switch is not output, control may be performed to return to a state where the operation handle 18 can be accepted.

(12-2. Peripheral board group)
The peripheral board group includes a sub-integrated board 111, a lamp driving board 119, an accessory control board 115, a display control board 120, and the like. Of these, the sub-integrated board 111 includes an integrated CPU 112, an integrated ROM 113, and an integrated RAM 114. The sub-integrated board 111 also includes a sound source IC 128 that performs control related to sound output, and also includes a sound ROM 127 as a read-only memory related to sound output. The integrated CPU 112 executes a process based on the effect command received from the main board 101 by executing the effect control program stored in the integrated ROM 113. Further, the integrated RAM 114 temporarily stores information such as various data and input / output signals generated in various processes executed by the sub-integrated board 111, effect commands received from the main board 101, and the like. When the integrated CPU 112 reads the effect command stored in the RAM 114, the integrated CPU 112 transmits a display command to the display control board 120 based on the read effect command, or sends a lamp lighting signal or solenoid to the lamp drive board 119. A drive signal is transmitted, or a drive signal is output to the frame lamp 27. In addition, the sub integrated substrate 111 reads out a sound output mode based on the effect command from the sound source IC 128 from the sound ROM 127 and outputs a drive signal corresponding to the read sound output mode to the upper speaker 29 and the lower speaker 14.

  The lamp driving board 119 transmits a lamp lighting signal received from the sub-integrated board 111 to the game board lamp, and transmits a solenoid driving signal received from the sub-integrated board 11 to the solenoid. The game board lamp and the solenoid are equipped in the effect device 42, and among these, the game board lamp is used for the light emitting effect in the effect device 42, and the solenoid is used to drive the movable decorative bodies 44a, 44b and 44c. Used. The lamp driving board 119 distributes the lamp lighting signal transmitted from the sub-integrated board 111 to each lamp (LED) and delivers it to the game board lamp, and also transmits the solenoid driving signal transmitted from the sub-integrated board 111 to the solenoid. The sub-integrated board 111 performs substantial control of the game board lamp and solenoid. Hereinafter, the lamp driving substrate 119 may be omitted for explanation.

  The display control board 120 includes a display CPU 121 as a central processing unit, a display ROM 122 as a read-only memory, and a display RAM 123 as a readable / writable memory. Among these, the display CPU 121 controls the liquid crystal display device 50 based on a display command from the sub-integrated substrate 111.

(12-3. Games on the game board)
Next, a game realized by the game board 4 provided with the various components and devices described above will be described. First, when the player twists the operation handle 18, a game ball is launched by the launching device 135 provided on the back side of the pachinko machine 1. When the game ball launched from the launching device 135 rises along the launch rail 15 and the guide rail 11, it is released to the upper part of the game area 12, and thereafter flows down while colliding with the obstacle nail or the like in the game area 12.

(12-3-1. Normal design)
When the game ball flowing down the game area 12 passes through the gate 58, the passage of the game ball is detected by the gate switch 174a. Based on this detection signal, the normal symbol display 144 (display area 64c) displays the fluctuation display of the normal symbol ( The display mode in which the LEDs are alternately lit in green and red is started.

  That is, when a game ball is detected by the gate switch 174a, the CPU 102 of the main board 101 extracts the normal random number per symbol from a counter that updates the normal random number per symbol within a predetermined range. Then, the CPU 102 determines whether or not to win based on the normal symbol determination random number at the start of the variation of the normal symbol by the normal symbol display 144, and in accordance with the determination result (in this embodiment, the hit) If there is a red lighting display, if it is off, a green lighting display is finally displayed).

  Further, when the game ball passes through the gate 58 while the normal symbol display 144 is displaying the fluctuation of the normal symbol, the random numbers determined by the normal symbol extracted by the CPU 102 are stored in the RAM 104 up to a predetermined number (four in this embodiment). Remembered. At this time, the stored number of determination random numbers per normal symbol is displayed according to the lighting mode of the normal diagram start storage LED 148 (light emitting area 64e). Specifically, when the passage of the game ball is detected by the gate switch 174a while the passage of the gate 58 is effective (when the number of start memories of the normal symbol is less than 4), the normal start memory LED 148 is detected each time. The lighting mode of is switched.

  In the present embodiment, for example, when the normal chart start memory number is 1, only one lower general chart start memory LED 148 (light emitting area 64e) is lit, and then when the general chart start memory number increases to 2, In addition to the lower side, the upper common start memory LED 148 (light emitting area 64e) is turned on (a mode in which two lights are turned on). Further, when the number of normal start memories increases to 3, the upper normal start memory LED 148 that has been simply lit up so far switches to a blinking state, and the lower normal start memory LED 148 remains in a simple lit state. When the normal start memory number reaches the maximum of 4, the two normal start memory LEDs 148 are in a blinking state. On the other hand, each time the normal symbol display is started on the normal symbol display 144, the number of memory for starting the normal symbol decreases by one. In this case, the normal symbol start is performed in the opposite manner to the above. The storage LED 148 is lit and blinks.

  In the present embodiment, when the CPU 102 determines that the winning is based on the random number for determining the normal symbol at the start of the variation of the normal symbol, the normal symbol display 144 (light emitting area 64c) is lit red after a predetermined period. It is stopped and displayed. After that, the solenoid 171a is switched to the operating state (energized state) to expand the left and right opening / closing members 56a, and control is performed to open the ball entry device 56 for a predetermined period (for example, 0.5 seconds). . As a result, it becomes possible to win the lower start opening 54. Thereafter, when a predetermined period of time elapses, the solenoid 171a is returned to a non-operating state (non-energized state) to return the opening / closing member 56a to the initial position and to control the ball entry device 56 to a closed state.

  On the other hand, when the CPU 102 determines that the normal symbol change starts based on the normal random number per symbol, the normal symbol display 144 (light emitting area 64c) is lit in green after a predetermined period. Only the stop display is made, and in particular, the ball entrance device 56 is not controlled to be in an open state. Therefore, in this case, it is still impossible to win the lower start opening 54, but it is still possible to win the upper start opening 52.

(12-3-2. Special design / decorative design)
When a game ball flowing down in the game area 12 wins the upper start port 52 or the lower start port 54, the winning of the game ball is detected by the start port switch 170a or the start port switch 170b. In this case, if the special symbol variation display is in a state where it can be started (for example, it is not in the big hit game or the special symbol / decorative symbol variation display state), the special symbol indicator 141 (four In the light emitting area 64a), the special symbol variation display is started, and the liquid crystal display device 50 starts the variation display of the decorative symbols (for example, designed numbers “0” to “9”). In the present embodiment, the special symbol is represented by a combination of lighting of the four light emitting areas 64a. Three decorative symbols are displayed on the screen of the liquid crystal display device 50, ie, a left decorative symbol, a middle decorative symbol, and a right decorative symbol, and all of these decorative symbols are sequentially scrolled on the screen in a certain direction. In this way, the display is changed.

  The change display of the special symbol or the decorative symbol is stopped after a predetermined period of time, and when the special symbol is displayed in a specific mode (a combination of lighting of the plurality of light emitting areas 64a that are big hits: jackpot symbol), At the same time, the stop symbols of the decorative symbols (the state in which all the left, middle and right decorative symbols are stopped) are also displayed in a specific manner (the same decorative symbol combination: jackpot symbol). In this case, the CPU 102 of the main board 101 starts control of the “hit game state”. Note that the period during which the variable display is performed is determined within a range of several seconds to several tens of seconds according to the jackpot determination random number or other random numbers.

  In the big hit gaming state, the CPU 102 controls the solenoid device 176a to operate to open the attacker device 60. That is, when the solenoid 176a is actuated, the opening / closing member 60a pivots with its lower edge portion as a fulcrum so as to fall down toward the front side of the pachinko machine 1, thereby making it possible to win a prize winning opening 62. Such opening control of the attacker device 60 is performed by a count switch 175a that a predetermined time (for example, 30 seconds) elapses or that a predetermined number (for example, 10) of game balls has won the big winning opening 62. This is continued until either condition is detected.

  When any of the above conditions is satisfied, the CPU 102 returns the solenoid 176a to a non-operating (non-energized) state, and raises the opening / closing member 60a that has been tilted forward until then along the board surface. As a result, the special winning opening 62 is closed, and the attacker device 60 is controlled to be closed. In the big hit gaming state, the CPU 102 repeatedly executes a control in which one cycle of opening and closing (hereinafter also referred to as a round) is performed until the attacker device 60 is opened and then returned to the closed state. 15 rounds), the big hit gaming state is ended there. As described above, since the big winning opening 62 is opened when the game state is changed to the big hit gaming state, the upper starting opening 52, the lower starting opening 54, and the general winning opening can be obtained by winning a game ball in the opened large winning opening 62. Since it is possible to acquire a large amount of game balls in a shorter time than winning game balls at 66, etc., it is possible to enhance the interest of the player.

  In the present embodiment, the left, middle and right decorative symbols are controlled to stop in the order of left decorative symbol → right decorative symbol → middle decorative symbol. The decorative symbol stop symbol is a symbol in which all the left, middle and right decorative symbols are stopped when the left, middle and right decorative symbols start to change and the middle decorative symbol is stopped. A combination of

  Further, in the present embodiment, the specific mode displayed when the special symbol is stopped includes a special mode (a combination of lighting of a plurality of light emitting areas 64a that are probable big hits), and the special symbol at the stop is a special mode. When displayed, the stop symbol of the decorative symbol is also in a special mode (probability big hit symbol: in this embodiment, a combination of the same odd symbols). In this case, it becomes a so-called “probable big hit”, and after the big hit gaming state is finished, the probability that the next big hit gaming state (winning probability) becomes high (in this embodiment, the probability variation state has a probability of 1/70. In other than the probability variation state, the probability is 1/490.) That is, when the special symbol at the time of stoppage is a special mode, it becomes a more advantageous state for the player in the “probability variation state” after the jackpot game is over.

  When the probability variation state is reached after the big hit game is over, so-called time reduction control is performed with the following contents. That is, in the probability variation state, the special symbol display 141 (four light emitting areas 64a) changes the time from the start of the special symbol variation display to the stop display of the special symbol, and the normal symbol display 144 (light emission). In the region 64c), control is performed to shorten the fluctuation time from the start of the normal symbol fluctuation display to the stop display of the normal symbol compared to the normal state. At the same time, control is performed to increase the probability that the result of the normal symbol variation display on the normal symbol display 144 (light emitting area 64c) will be “winning”. Further, when the normal symbol variation display is “winning”, the opening time of the opening / closing member 56a is extended from the normal state (in this embodiment, 0.5 seconds in the normal state, the short-time state and the probability variation). (In this state, 0.8 seconds), and control for increasing the number of times the pitching device 56 is opened more than in the normal state (in this embodiment, once in the normal state, three times in the short-time state and the probability variation state). Done.

  On the other hand, even if the special symbol at the time of stoppage is displayed in a specific mode, if it is a non-special mode (a combination of lighting of a plurality of light emitters that become a non-probable big hit) different from the above-mentioned special mode, The stop symbol of the decorative symbol is also in a non-special mode (non-probable big hit symbol: in this embodiment, a combination of the same even number symbols), and the time reduction control is performed with the following contents. That is, after the end of the big hit gaming state, the number of times the special symbol variable display is executed on the special symbol display 141 (four light emitting areas 64a) reaches a predetermined number (100 times in the present embodiment). Then, control is performed to shorten the variation time of the special symbol and the variation time of the normal symbol from the normal state. In addition, when the result of the normal symbol variation display is “winning”, the control for extending the opening time of the opening / closing member 56a from the normal state and the control for increasing the number of opening times of the opening / closing member 56a from the normal state is performed. Executed. In these short-time states, the winning probability to the lower start port 54 increases until the number of special symbol fluctuation displays executed by the special symbol indicator 141 reaches a predetermined number of times, and within a certain period of time. Since the number of executions of the special symbol variation display can be increased (that is, the lottery opportunity for the big hit is increased), the player is more advantageous to that extent. In the probability variation state described above, in addition to the time reduction control, the probability that the normal symbol variation display result is “hit” on the normal symbol display 144 is increased, which is more advantageous to the player than the time reduction state. It becomes a state. The normal state means a state that is not the probability variation state or the time-short state described above.

  In the present embodiment, a game ball is won at the upper start opening 52, and three game balls are paid out as a specified number when detected by the start opening switch 170a. When a winning is made and detected by the start switch 170b, a predetermined number of four game balls are paid out. Thus, the reason why the number of payouts is different between the upper start port 52 and the lower start port 54 is as follows.

  In other words, the lower start port 54 is normally closed by the opening / closing member 56a and has a structure in which there is no chance of winning unless the result of the normal symbol variation display is “winning”, whereas the upper start port 52 is Since it is a structure that can always accept a game ball from above, if there are too many payouts per game ball to the upper start opening 52, the player will be too advantageous compared to the game hall operator. . If it does so, winning a prize to a starting opening (upper starting opening 52 and lower starting opening 54) will be controlled as a measure of a disadvantage elimination of a game hall operator, and it will be judged whether it will be in a lottery game (a big hit game state as a result) ) May cause discomfort to the player. On the other hand, if the number of payouts for winning at the upper start opening 52 is too small, the number of game balls required for the lottery game increases, resulting in excessive investment and inconvenience to the player. It will give you a profit.

  On the other hand, the lower start port 54 provides a game advantageous to the player in the short-time state and the probability variation state, and the lower start port 54 is controlled by extending the opening time and the number of opening times of the opening / closing member 56a. The probability of winning is increased. However, if the number of payouts for winning a game ball is too small, the number of payouts will be reduced relative to the number of shot balls, and the remaining number of game balls will gradually decrease in spite of the advantageous game state. By doing so, the player will be uncomfortable. In consideration of these events, in this embodiment, the number of payouts (three or four) for each of the upper start port 52 and the lower start port 54 is set.

  In addition, the display result of the special symbol on the special symbol display 141 corresponds to the display result of the decorative symbol on the liquid crystal display device 50. That is, when it is determined that a big hit is not made at the start of the variation of the special symbol, the LED (four light emitting areas 64a) is turned on according to a mode different from the above specific mode, that is, a mode out of the special mode. In addition to the stop display, the liquid crystal display device 50 displays an image of a decorative symbol in a manner of loss (a loss symbol: a symbol other than a jackpot symbol, in this embodiment, a combination of at least two types of identification information (symbols)). .

  Also, the decorative symbol is a symbol for the production different from the special symbol, and the contents of the special symbol variation display (flashing of the four light emitting areas 64a) are expressed in a dramatic manner by the variation display of the ornamental decoration symbol. This enhances the visual effect. In other words, when the LED of the special symbol display 141 is turned on and displayed in a specific manner, control to shift to the big hit gaming state is performed, but by any chance, the display result of the decorative symbols in the liquid crystal display device 50 becomes a specific manner. However, when the LED in the special symbol display 141 is not lit and displayed in a specific manner, control for shifting to the big hit gaming state is not performed.

  Further, in this embodiment, it is possible to control to one type of big hit gaming state in which “15 times” is set as the number of rounds executed in the big hit gaming state, but the benefits given to the player as the big hit gaming state are different. It may be configured to be controllable to multiple types of big hit gaming states. For example, it may be configured to control to a plurality of types of jackpot gaming states with different numbers of rounds executed in the jackpot gaming state. In this case, after determining the big hit based on the big hit determination random number, the number of rounds to be executed in the big hit gaming state may be determined, or different round numbers may be set based on the big hit determination random number It may be determined whether to control any one of the plurality of types of big hit gaming states.

  In the present embodiment, the state display LED 145 (light emitting region 64b) is controlled to be lit in red in the above-described probability variation state, and is controlled to be lit in green in the short-time state. Then, when the short-time state or the probability variation state ends and the normal state is reached, or when the game state shifts to the big hit gaming state, the state display LED 145 (light emitting area 64b) is turned off.

  In the present embodiment, the jackpot type display LED 146 (two light emitting areas 64d) is turned on during the jackpot game. Specifically, one or both of the upper and lower two light emitting areas 64d that become the big hit type display LED 146 are turned on according to the type of the big hit gaming state. In this embodiment, since it is possible to control only one type of big hit gaming state, it is not necessary to turn on the big hit type display LED 146, but when configured to be controllable to a plurality of types of big hit gaming state, By controlling on / off of the big hit type display LED 146 corresponding to the big hit game state, the type of the big hit game state can be easily grasped from the outside.

  For example, as a plurality of types of jackpot gaming states, the first jackpot gaming state in which “2 times” is set as the number of rounds executed in the jackpot gaming state, and the number of rounds executed in the jackpot gaming state is “15 times”. It is assumed that the second big hit gaming state in which "" is set is executable. In this case, the LED corresponding to the upper light emitting area 64d of the big hit type display LED 146 is turned on during execution of the first big hit gaming state, and the LED corresponding to the lower light emitting area 64d is executed during execution of the second big hit gaming state. You may make it perform control to light. Thus, it is understood that the pachinko machine 1 according to the present embodiment can be adapted to a configuration that can be controlled to a plurality of types of big hit gaming states.

(13. Modifications / Additional matters)
The present invention can be implemented with various modifications without being limited to the above-described embodiment.

  (1) In the above-described embodiment, in addition to the front-side ball guide member 70 to be evaluated, up to the back-side ball guide member 72 is detachable from the rear unit 42b. However, the back-side ball guiding member 72 may be formed integrally with the rear unit 42b. That is, the back-side ball guiding member 72 is not directly related to the evaluation of the ball guiding performance unlike the front-side ball guiding member 70, and therefore the present invention can be implemented even if it is a structure integrated with the rear unit 42b. This is because there is no hindrance.

  (2) In one embodiment, when the game balls that have not been guided to the discharge passage 72d by the ball guide member 70 move to the lower edge of the front unit 42a, they are collected in the central portion (above the discharge port 72e). However, the game ball may be dropped from a position left and right away from the central portion. In this case, since the winning probability when the game ball is guided to the discharge passage 72d can be relatively increased, the effect of increasing the player's expectation for the movement of the game ball on the ball guide member 70 is increased.

  (3) In one embodiment, the ball guide member 72 on the back side is screwed to the rear unit 42b together with the ball guide member 70 to be exchanged, but these may be fixed separately.

(4) In one embodiment, the engagement piece 42s protruding toward the front unit 42a is formed, and the engagement hole 42h for receiving the engagement piece 42h is formed toward the rear unit 42b. The positional relationship may be reversed.

  (5) In addition, the specific forms of the front unit 42a and the rear unit 42b mentioned in the embodiment are merely examples, and it goes without saying that these can be appropriately modified.
