TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gaming machine such as a pachinko machine provided with a variable winning device having a shutter and an electric driving means for operating the shutter.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as one type of gaming machine, a pachinko machine equipped with a special symbol display device for variably displaying a plurality of symbols and the like in a predetermined arrangement has been known.
[0003]
In this type of pachinko machine, according to the display symbol (stop symbol) when the variable display is stopped on the display device, a “special game state” which is in a state advantageous to the player after the reach state, and a “special game state” after the reach state A "disengagement reach state" that does not enter the special game state, or a "disengagement state" that does not go through the reach state and does not become the special game state is generated. The stop symbols include a special game symbol (big hit symbol) for generating a special game state, a detachable reach symbol for generating a detached reach, and a detached symbol for generating a detached state.
[0004]
In the pachinko machine as described above, a game state that changes according to a player's operation satisfies a predetermined condition (for example, a game ball wins an operating port, etc.), and a special symbol display device is used. , The symbol variation display is started. In addition, a stop symbol corresponding to the game situation is selected from the special game symbol, the off-reach symbol, and the off symbol, and the variable display is stopped at the selected stop symbol. Then, when stopping at the big hit symbol, the special variable winning device (variable winning device) is switched so as to be in an advantageous state (big hit state) for the player. More specifically, the player can acquire a large amount of premium balls by tilting the shutter to open a large winning opening and allowing many gaming balls to win there.
[0005]
Such a variable winning device generally has a large winning opening, and a shutter is provided in front of the large winning opening. The shutter is operated by a special winning opening solenoid provided on the side of the special winning opening, and opens and closes the special winning opening. More specifically, when the solenoid is in an excited state (driving state), the shutter is tilted substantially horizontally, thereby opening a special winning opening. In addition, when the solenoid is in the non-excited state (non-driven state), the shutter is in a substantially vertical state, whereby the special winning opening is closed.
[0006]
[Problems to be solved by the invention]
However, in recent years, various fraudulent activities have been reported with respect to the variable winning device. As a typical example of the misconduct, a thin long resin plate called a “cell” is inserted into the pachinko machine (between the game board and the glass plate) from a game ball passage or the like of the upper plate of the pachinko machine, and the shutter is released. Forcibly tilting the large winning opening to an open state, and illegally winning a large amount of game balls in the large winning opening in the open state. When such misconduct is performed, a large amount of prize balls are illegally derived, and as a result, there has been a case where a great deal of damage is caused to the game arcade.
[0007]
As a specific method of opening the special winning opening using the above-mentioned “cell”, a method of directly tilting the shutter by hooking the tip of the “cell” to the shutter, or operating the plunger of the solenoid (setting the plunger There is a method of tilting the shutter by immersing the shutter against the urging force of the coil spring). In particular, in the former fraud, the operation target member who intends to perform the fraud is a shutter that can be directly visually recognized from the outside, and therefore, the fact is that the fraud is performed relatively frequently.
[0008]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to provide a pachinko machine equipped with a variable prize device having a shutter and an electric drive unit for operating the shutter. Another object of the present invention is to provide a gaming machine capable of more reliably preventing fraud without impairing the function of the variable winning device.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, in the first aspect of the present invention, the player takes the second state, thereby making it easier for the player to enter the winning opening of the game medium than when the player takes the first state. A shutter, and an electric driving means for operating the shutter, wherein the shutter always takes a first state, and the shutter takes a second state on condition that a specific condition is satisfied. In a gaming machine provided with a variable winning device having a control means for driving and controlling the electric drive means,
When the shutter is in the first state, holding means is provided for holding the shutter in the first state against a force acting on the shutter to cause the shutter to assume the second state. The holding function of the holding means is disabled when the shutter is taken to the second state by the dynamic driving means.,
The holding unit includes an operation unit that can be externally operated, and the holding function of the holding unit is disabled even when a predetermined operation is performed on the operation unit.That is the gist.
[0010]
Also,The operation unit may be externally operable at a position separated from the shutter. In addition, after the holding function of the holding unit is invalidated by a first external operation on the operation unit, thereafter, the holding function is disabled by a second external operation on the shutter. The shutter may be in the second state. Further, the operation section may be constituted by a lever exposed from an opening formed at a position apart from the winning opening, and in order to prevent a game ball from hitting the lever. May be provided. Also,The winning opening can be closed by the shutter taking a first state, and the winning opening can be opened by the shutter taking a second state by tilting.May be.
[0011]
(Action)
According to the gaming machine of the first aspect, the electric drive means is set to the non-drive state by the control device so that the shutter always takes the first state. In addition, the controller drives and controls the electric driving means under the necessary condition that the specific condition is satisfied, whereby the shutter is operated and the second state is established. By taking the shutter in the second state, it becomes easier for the game medium to enter the winning opening than when the shutter is in the first state.
[0012]
By the way, according to the gaming machine, when the shutter is in the first state, even if an attempt is made to exert a force acting on the shutter to cause the shutter to take the second state based on cheating, the holding means , The shutter is held in the first state. Therefore, it is possible to suppress the shutter from forcibly entering the second state by the wrongdoer. On the other hand, when the electric drive unit is driven, the holding function of the holding unit is disabled. For this reason, when the drive of the electric drive is properly controlled by the controller, the shutter can be in the second state without any hindrance.Further, the holding means has an operation unit which can be operated externally, and the holding function of the holding means is invalidated even when a predetermined operation is performed on the operation unit.
[0013]
Also,Claim 6According to the gaming machine of the present invention, in addition to the operation of the gaming machine of the first invention, the winning opening is closed by the shutter taking the first state, and the shutter takes the second state by tilting. As a result, the winning opening can be opened. Therefore, the winning means is held closed by the holding means even if the shutter is tilted to open the winning opening due to dishonest act or to exert an acting force. Therefore, it is suppressed that the winning opening is forcibly opened by the wrongdoer. On the other hand, when the electric driving unit is driven, the holding function of the holding unit is invalidated, so that when the electric driving unit is properly driven and controlled, the shutter is tilted without any hindrance, The winning opening is opened.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a pachinko machine as a gaming machine will be described below in detail with reference to the drawings.
[0015]
As shown in FIG. 1, a front frame 2 is attached to the outer frame 1 so as to be rotatable about a rotation axis. In the figure, the front frame 2 is in a closed state. A game board 3 (see FIG. 2), a glass door frame 4 having a glass plate, an upper plate 5, a lower plate 6, a handle 7, and the like are mounted on the front frame 2. A speaker 8 is embedded in the front frame 2 on the side of the upper plate 5. The speaker 8 emits various sound effects as the game progresses, and notifies the player of the game state by voice.
[0016]
Next, the configuration on the gaming surface of the gaming board 3 will be described. As shown in FIG. 2, the gaming board 3 is provided with a symbol operating port 12, a symbol display device 13, a special winning port 14, a starting port 15, a variable winning device 21 having a large winning port 16, and the like. I have.
[0017]
The symbol operation port 12 is provided at a lower center portion of the game board 3. The symbol display device 13 is provided at the center of the game board 3 and includes a display unit 13a composed of an LCD (liquid crystal display), on which a plurality of symbol columns are displayed. For example, three symbol columns (not shown) of a left symbol column, a middle symbol column, and a right symbol column are displayed as these symbol columns (other symbol columns may be displayed).
[0018]
In the symbol display device 13, the symbol variation of each symbol row is started based on the winning (or passing) of the game ball B to the symbol operating port 12. The "winning" here includes not only the case of paying out the premium ball, but also the simple passing without paying out the premium ball. When the symbol change in all the symbol rows is stopped, the combination of the displayed symbols is a predetermined combination, that is, the combination of the symbols when the same type of symbols are arranged on a straight line (hit line). , May be. Examples of this combination include “7”, “7”, and “7”. Such a combination of symbols is hereinafter referred to as a "winning symbol". In addition, as a display mode of the symbol in the symbol display device 13, in addition to the above-mentioned one line, five lines (three upper and middle lower horizontal lines and two oblique lines) and two lines (upper and lower horizontal lines) are used. It may be a type having a hit line called two lines or two oblique lines or three lines (one horizontal center line and two oblique lines).
[0019]
In a pachinko machine, a reach game state (reach state) occurs before the occurrence of the above-mentioned "hit". Here, the reach state refers to a state immediately before the occurrence of a hit, for example, symbol fluctuation in the right symbol row stops at the same type of symbol as the left symbol row on the hit line, and thereafter, the middle symbol If the symbol change in the row is stopped with the same type of symbols as the stopped symbols in the left and right symbol rows, a state of a winning combination is finally included. In addition, in the above-mentioned reach state, the symbol fluctuation of the middle symbol row finally stops at a symbol (hit symbol) of the same type as the stop symbol of both the left and right symbol rows and becomes a hit state. , And those that stop at a different type of symbol (this is referred to as a “missing reach symbol”) and do not enter a hit state (hereinafter, referred to as a “missing reach state”).
[0020]
The special winning opening 14 is generally called an electric accessory, and is provided at an upper portion of the symbol display device 13. The specific winning opening 14 is also a winning device provided with a blade 14a. The blade 14a is operated by a specific winning opening solenoid (not shown). That is, when the solenoid is in the excited state, the blade 14a is opened, and the game ball B can be won in the specific winning opening 14. In a normal state, the solenoid is in a non-excited state. In this state, the specific winning opening 14 is closed, and it is difficult (impossible) to win the game ball B in the specific winning opening 14.
[0021]
In the present embodiment, when the symbol is hit on the symbol display device 13 and stopped at the symbol, the blade 14a is opened for a predetermined time α (for example, α = 5.9 seconds). Then, a predetermined number (for example, three) or more of the game balls B wins the specific winning opening 14, and based on the fact that the winning is detected, a big hit state described later occurs.
[0022]
By the way, when a predetermined number (for example, three) or more game balls B win the specific winning opening 14 and a big hit state occurs, the special device is activated. The operation of the special device is a necessary condition for operating the special electric accessory, generating a jackpot state as a special game state advantageous to the player, and acquiring more prize balls. In the present embodiment, the special electric accessory is an electric accessory that opens the entrance of the special winning opening 16.
[0023]
Further, the starting port 15 is a winning port related to winning of the game ball B for activating the special electric accessory, and includes the rotating body 17 and a winning port (not shown). The starting port 15 is provided on the right side of the symbol display device 13 and has a passage for the game ball B. The entrance 15 a of this passage is open at the upper end of the starting port 15. A rotating body 17 having a ball receiving portion 17a is supported in the middle of the passage. A driving motor (not shown) is drivingly connected to the rotating body 17, and the rotating body 17 is always rotated at a constant speed by the motor. When the game ball B enters the entrance 15a when the ball receiving portion 17a is not opposed to the entrance 15a of the passage, the game ball B is made to stand by at that position. When the ball receiving portion 17a faces the entrance with the rotation of the rotating body 17, the game ball B enters the ball receiving portion 17a. The game ball B is carried downward by the rotation of the rotating body 17, and is guided to a winning opening (not shown) when the ball receiving portion 17a reaches a predetermined position other than the uppermost position. By the winning of the game ball B, the special electric accessory described above is operated.
[0024]
The rotation speed of the rotator 17 is set to a value that makes one rotation over a slightly longer time than one opening of the special winning opening 16. This is to suppress a problem that the game ball B is detected by the start-up switch 43 described later during opening of the special winning opening 16 and the game is shifted to the next round even though the round is in progress. is there.
[0025]
The variable winning device 21 having the large winning port 16 is provided below the symbol operating port 12. A winning passage is provided in the back of the special winning opening 16, and the game ball B that has won the special winning opening 16 is guided to a winning ball collecting unit (not shown) through the winning passage. In addition, a shutter 22 is provided in front of the special winning opening 16. The shutter 22 is operated (tilted) by a special winning opening solenoid 23 as an electric driving means provided on a side of the special winning opening 16 to open and close the special winning opening 16. The cycle of opening and closing the special winning opening 16 is repeated a fixed number of times (for example, 16 times), which corresponds to the above-described jackpot state. The large winning opening 16 is closed when one of the following two conditions is satisfied first after being opened. The conditions are (1) a predetermined number (for example, 10) of the gaming balls B winning in the special winning opening 16 and (2) a predetermined time (for example, 9.5 seconds) has elapsed since the opening of the special winning opening 16. It is to be.
[0026]
Further, in the present embodiment, the game board 3 is provided with various detection switches in order to detect a gaming state of the pachinko machine that changes according to the operation of the player. As the detection switch, a symbol operating switch 41 provided corresponding to the symbol operating port 12, a specific winning opening switch 42 provided corresponding to the specific winning opening 14, provided corresponding to the starting port 15. And a count switch 44 provided corresponding to the special winning opening 16. The symbol operating port switch 41 detects a winning of the game ball B to the symbol operating port 12, the specific winning port switch 42 detects a winning of the gaming ball B to the specific winning port 14, and a starting port switch. 43 detects the winning of the game ball B to the starting port 15 (winning to the above-mentioned not-shown winning port). The count switch 44 detects the winning of the game ball B into the big winning opening 16.
[0027]
In the present embodiment, based on the detection results of the respective switches including the symbol operating port switch 41, the specific winning port switch 42, the starting port switch 43, and the count switch 44, the symbol display device 13, the specific winning port A control device 50 is provided for controlling the driving of the solenoid, the special winning opening solenoid 23, and the like. The control device 50 constituting the control means includes a read-only memory (ROM), a central processing unit (CPU), a random access memory (RAM), and the like. The ROM stores a predetermined control program and initial data in advance, and the CPU executes various arithmetic processes according to the control program of the ROM. The RAM temporarily stores the calculation result by the CPU in various symbol random number buffers, symbol random number areas, stopped symbol areas, and the like.
[0028]
Now, a characteristic portion in the present embodiment will be described. As described above, the variable winning device 21 in the present embodiment includes the special winning opening 16, the shutter 22, and the special winning opening solenoid 23. As shown in FIGS. 3, 4, and 5, the special winning opening 16 is formed in an opening substantially at the center of a mounting member 24 mounted on the game board 3. Further, the shutter 22 is pivotally supported at its lower part so as to be tiltable with respect to the mounting member 24.
[0029]
A back box 25 is mounted on the back side of the mounting member 24, and the big winning opening solenoid 23 and the electric wiring board 30 are mounted on the back box 25. The large winning opening solenoid 23 includes a main body 26, a plunger 27, and a coil spring 28 (see FIGS. 6, 7 and the like), and the plunger 27 can protrude and retract from the main body 26. The coil spring 28 is provided between the distal end portion of the plunger 27 and the main body 26, and is normally operated by the urging force of the coil spring 28 (the non-excited state (off state: non-driven state of the special winning opening solenoid 23). ), The plunger 27 projects from the main body 26. On the other hand, when the solenoid 23 is in the excited state (on state: driving state), the plunger 27 is immersed in the main body 26 against the urging force of the coil spring 28.
[0030]
Further, an arm 29 is attached and fixed (or integrally formed) to the tip of the plunger 27, and the arm 29 moves up and down together with the plunger 27. A pair of upper and lower projections 31 and 32 extending toward the shutter 22 (player side) are integrally formed on the arm 29, and a groove 33 is formed between the projections 31 and 32. On the other hand, a convex portion 34 is formed integrally with a lower portion of one side of the shutter 22. The projection 34 can be accommodated in the groove 33 between the projections 31 and 32.
[0031]
With this structure, when the solenoid 23 is excited and the plunger 27 is immersed in the main body 26, the arm 29 (projection 31) moves upward as shown in FIG. Is lifted by the raised projection 31, and the shutter 22 tilts. As a result, the special winning opening 16 is in an open state (second state), and it becomes easy for the game ball B to win the special winning opening 16. However, the width (height) of the groove 33 is formed to be larger than the width of the projection 34, and the projection 31 does not hit the projection 34 when the arm 29 is slightly moved upward. ing. That is, the tilting of the shutter 22 is started only after the arm 29 moves upward by a predetermined amount or more.
[0032]
After that, when the solenoid 23 is de-energized and the plunger 27 projects from the main body 26, the arm 27 (projection 32) moves downward as shown in FIG. Is pressed down by the lowered projection 32, and the shutter 22 returns to the vertical state. As a result, the special winning opening 16 is closed (first state), and it is difficult (impossible) for the game ball B to win the special winning opening 16.
[0033]
The mounting member 24 is provided with a housing 35 that forms a winning ball passage or the like so as to extend to the back of the special winning opening 16. The housing 35 is provided with the count switch 44 and the like.
[0034]
Further, a pair of support members 36 are formed at one side lower portion of the mounting member 24 so as to protrude, and a lock lever 37 is rotatably supported by the support members 36. One end of the lock lever 37 is exposed from an opening 24a formed in a lower portion of one side of the attachment member 24 at a position separated from the special winning opening 16, so that a person related to the game arcade (for example, a clerk) can use the glass door. After the frame 4 is opened, the lock lever 37 can be turned (up and down) from the front side of the mounting member 24. A step 38 is formed in the lower portion of the lock lever 37 in the vicinity of the shaft support, and an engagement protrusion 39 extending toward the lock lever 37 is integrally formed on the shaft support of the shutter 22. Further, a weight 37a is buried in the other end of the lock lever 37, and the engagement projection 39 is always engaged with the step 38 by the action of the weight 37a (see FIG. 7A ) See). In the present embodiment, the lock lever 37, the engagement protrusion 39, and the like constitute a holding unit. When the engagement protrusion 39 is engaged with the step 38, the shutter 22 is tilted. Even if stress is applied to the shutter 22, the shutter 22 is not tilted.
[0035]
At the same time, a lever pin 29 a is formed on the arm 29 so as to project perpendicular to the lock lever 37. The lever pin 29a is in contact with the lower end of the other end of the lock lever 37, and when the arm 29 moves upward, the lever pin 29a locks against the gravity of the weight 37a. The other end side of 37 is lifted, whereby the engagement state of the engagement protrusion 39 and the step portion 38 is released. In addition, on both sides of the special winning opening 16, resin side decorations 40 for preventing the game balls B from hitting the lock lever 37 are provided.
[0036]
Next, the operation and effect of the present embodiment will be described.
[0037]
According to the present embodiment, as shown in FIG. 7A, when the special winning opening solenoid 23 is in the non-excited state, the shutter 22 is maintained in the vertical state, and the special winning opening 16 is closed. At this time, even if an attempt is made to exert a force to pry open the shutter 22 by fraudulent action using a “cell” or the like, the engaging projection 39 of the shutter 22 is engaged with the step 38 of the lock lever 37 by the holding means. The shutter 22 remains in the vertical state. Therefore, it is possible to suppress the shutter 22 from being forcibly tilted by a fraudulent person, and to prevent fraudulent behavior.
[0038]
On the other hand, when the special winning opening solenoid 23 is driven, the holding function of the holding means is invalidated. More specifically, as shown in FIG. 7B, when the solenoid 23 is in the excited state and the arm 29 moves upward, first, the lever pin 29a is turned on the lock lever 37 against the gravity of the weight 37a. Lift the other end. Thereby, the engagement state of the engagement protrusion 39 and the step portion 38 is released.
[0039]
Thereafter, as the arm 29 further moves upward, as shown in FIG. 7C, the protrusion 34 of the shutter 22 is lifted by the protrusion 31 of the arm 29 that has moved upward, and the shutter 22 tilts. As a result, the special winning opening 16 is in an open state, and the winning of the game ball B to the special winning opening 16 is facilitated. That is, when the special winning opening solenoid 23 is properly driven and controlled, the shutter 22 can be in the open state without any hindrance. As a result, the function and effect described above can be obtained without impairing the function as the variable winning device 21.
[0040]
Further, in the present embodiment, the arm 29 is provided on the special winning opening solenoid 23, and the shutter 22 is tilted based on the operation of the arm 29. For this reason, the degree of freedom (arrangement position) and the like of the special winning opening solenoid 23 can be given.
[0041]
Further, in the present embodiment, one end side of the lock lever 37 is exposed from the opening 24a so that the lock lever 37 can be externally operated. For this reason, for example, when the ball is clogged in the winning passage, or when it is desired to pay out the service ball based on insufficient payout or the like, a person related to the game arcade (a clerk or the like) opens the glass door frame 4 and By operating the one end side of the lock lever 37 downward, the engaged state can be easily released. As a result, even if a situation in which the shutter 22 is to be opened legitimately occurs other than when the big hit state occurs, it is possible to sufficiently cope with the situation.
[0042]
Further, in the present embodiment, since the exposed position of the lock lever 37 is separated from the shutter 22, the lock lever 37 may be operated by a person who uses fraud by using a “cell” or the like. Therefore, it is very difficult to tilt the shutter 22 at a time. As a result, the above-described operation and effect of preventing fraud can be achieved more reliably.
[0043]
Further, in the present embodiment, the width (height) of the groove 33 of the arm 29 is formed larger than the width of the projection 34 of the shutter 22. Therefore, when the arm 29 is slightly moved upward, the tilting operation of the shutter 22 is not started because the projection 31 does not hit the projection 34, and the engagement state of the engagement projection 39 and the step 38 is first released. You. After that, the tilting of the shutter 22 is started only after the arm 29 moves upward by a predetermined amount or more. For this reason, it is possible to suppress a problem that occurs when the release operation and the tilting operation of the shutter 22 are performed (for example, the shutter 22 becomes unable to tilt by starting the tilting operation before the release). be able to.
