Description

  The present invention relates to a gaming machine for playing with a game ball as a medium.

  As this type of gaming machine, pachinko and other bullet ball gaming machines are well known.

  The gameability of a ball game machine is not limited to competing for the winning of a game ball to a specific winning opening that triggers in order to win a jackpot that results in a special gaming state. There are also cases where the player enjoys various effects that are provided in the center of the game board and are operated by operating various devices called so-called “instruments”.

Conventionally, the following documents are known as patent documents according to the present invention.
JP 2004-65485)

  By the way, in various effects by an effect device and other effect devices, unexpectedness and high game play are required, and game machine manufacturers are researching day and night for that purpose.

  The present invention has been made in view of such a situation, and a problem to be solved is to provide a game machine having a surprising effect different from that in the past.

  The present invention employs the following means in order to solve the above problems.

  That is, the gaming machine of the present invention is a game machine in which a game ball is played in the middle of a fall in a gaming machine in which a player aims to win a prize by naturally dropping a game ball provided for gaming on the game board. The game ball collides with the stage having a plurality of holes and the direction in which the game ball can move in and out of the hole of the stage and exits the hole. And an obstacle execution means for causing the obstacle to appear in and out of the hole, and the protrusion and execution means is a cylindrical body disposed under the stage and having a plurality of protrusions, A driving unit that rotationally drives the cylindrical body; and a control unit that controls the driving unit, and the obstacle is one of the plurality of protrusions when the cylindrical body is rotated by the driving unit. Receiving the pressing force of the hole Characterized in that it is pushed up on Luo stage.

According to the present invention, when the drive unit rotates the cylindrical body while being controlled by the control unit, the protrusion provided on the cylindrical body also rotates together with the cylindrical body.
In order to make an obstacle appear and disappear with respect to the stage, it may be pushed up directly by the projection of the cylindrical body, or a cam or other mediator is interposed between the projection and the obstacle, and the mediator is moved by the pressing force of the projection. It may be actuated to push the obstacle onto the stage by an intermediary. In any case, the obstacle may be pushed up on the stage by the pressing force of the plurality of protrusions.

  When there is an obstacle on the stage, the game ball that rolls on the stage is obstructed by the obstacle or forced to change its direction of travel. It is also a rule that the obstacles appear and disappear irregularly with respect to the stage depending on the formation and arrangement of the plurality of protrusions on the cylindrical body and the control of the control unit that controls the driving unit that rotates the cylindrical body. It can also be haunted.

  The plurality of protrusions may include a relatively long protrusion and a short protrusion. If the lengths of the protrusions are different, the duration of the pressing force due to the protrusions acting on the obstacle changes, and the longer the protrusion, the longer the pressing force duration. For this reason, the obstacle stays on the stage for such a long time. If the obstacle stays on the stage for a long time, the probability of the game ball hitting the obstacle increases, the direction of the game ball flowing down changes, and the game ball may be temporarily stopped by the obstacle. As a result, the speed at which the game ball flows down also changes. Of course, all the protrusions may have the same length.

The control unit can actuate the driving unit when a predetermined condition is met during the game, and can rotate or turn the cylindrical body in a direction and an angle determined in advance according to the condition.
An example of the predetermined condition is that a game ball enters a specific winning opening such as a start opening.
If a plurality of obstacles are prepared and the predetermined conditions are met, a plurality of obstacles may appear on the stage at the same time. The road can be formed by a plurality of obstacles. If a start opening and other winning openings are arranged at the end of the guideway, the winning rate is increased and the interest is enhanced. The predetermined direction may be either one of the clockwise direction or the counterclockwise direction, or both of these directions. Rotation means turning more than one turn, and turning means turning within a certain range of angles. Say.

  The obstacle may be a rotatable eccentric cam provided in the hole. The eccentric cam does not protrude on the stage due to its own weight when the protrusion is not in contact, and protrudes on the stage according to the rotation of the cylindrical body when the protrusion is in contact. Keep it. Since the cam that rotates in the eccentric state is an obstacle because it is in the eccentric state, the movement as the obstacle can be changed and the interest is enhanced.

  The obstacle may be a windmill. Further, an eccentric cam can be provided between the windmill and the cylindrical body. Since the windmill moves with respect to the stage by the eccentric cam and rotates at the same time, the change in the flow of the game ball hitting the windmill is large, which is more interesting than the case where the obstacle simply appears.

  Where the game ball flows down from one end side, which is the upstream side of the stage, toward the other end side, which is the downstream side, and where the game ball dropped from the other end of the stage is easy to win in the game board It is preferable to have a winning opening because it is easy to win. An example of the winning opening in this case is a starting port.

It is also conceivable that the tubular body can be seen entirely or partially from the player side.
Since the movement of the cylindrical body affects the winning of the game ball to the winning opening, if the player can grasp even a part of the movement of the cylindrical body, the expectation for winning can be enhanced.

According to the present invention, since it is difficult to predict when and where the game ball rolling on the stage hits the eccentric cam , the direction in which the game ball flows down on the stage cannot be predicted. In addition, the game ball may be temporarily stopped by the eccentric cam . Therefore, the flow of game balls changes and is not monotonous. Therefore, an unprecedented production effect can be expected.

  Hereinafter, preferred embodiments of a gaming machine according to the present invention will be described with reference to the drawings.

The case where Example 1 is applied to the pachinko gaming machine 1 will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the pachinko gaming machine 1 is a first type gaming machine called a so-called seven machine or a fever machine.

  In the pachinko gaming machine 1, when the player operates the handle 10 and puts the pachinko ball B into the start opening 5 which is a specific winning opening provided in the game board 3, the pattern provided in the center of the game board is displayed. A center accessory 7 having the variable display device 6 as a main component operates. Then, after the symbol variation display device 6 is activated, the symbol variation display device 6 is stopped. At that time, if a combination of symbols representing a certain picture or number is aligned with the display screen 6 a of the symbol variation display device 6, a big hit is obtained. Note that a passing ball detection sensor 19 (see FIG. 12) is provided at the start port 5, and when the pachinko ball B is detected by the passing ball detection sensor 19, the symbol variation display device 6 is activated.

  When the jackpot is reached, the big winning opening (commonly called “attacker”) 9 is actuated and opened widely, and the open state is maintained until 30 seconds or 10 pachinko balls are won. There is a specific area called “V zone” (not shown) in the big prize opening. If one of the ten pachinko balls B that won the prize passes the V zone, the big prize opening 9 is once closed and then the big prize is won again. The opening / closing operation is repeated until the mouth 9 opens and reaches a predetermined number of times (number of rounds).

  In addition, an electric tulip 11 is provided between the start opening 5 and the special winning opening 9, and the center accessory 7-starting opening 5-electric tulip 11-large winning opening 9 are arranged in a straight line. Various devices are arranged line-symmetrically around these. A large number of nails 12 are arranged on the entire surface of the game board 3 with a certain regularity at an appropriate interval.

  The various devices include, for example, the ramp windmill 13, the passage gate 15 located below the lamp windmill 13, the plastic windmill 17 scattered below the passage gate 15, and various winning chuckers 18 located further below the plastic windmill 17. -Side lamps and other electrical decorations 21 provided along the periphery of the game board 3 in the vicinity of the plastic windmill 17 may be mentioned.

  Further, below the symbol variation display device 6 of the center accessory 7, a pachinko ball B passing through a number of nails 12 planted around the center accessory 7 or passing through a warp route (not shown). , The stage 8 is a place to play in the center accessory 7 before entering the starting port 5.

  After the pachinko ball B entering the stage 8 flows down from the one end side which is upstream of the stage 8 toward the other end side which is downstream, the pachinko ball B which has dropped from the other end of the stage 8 is the start port 5. In order to make it easier to win a prize, not only the installation position on the game board has been devised, but also various stages are provided on the stage itself to enhance the interest of the player.

Hereinafter, the stage 8 will be described in detail.
3 and 4 are enlarged perspective views of the stage 8. The stage 8 has a stage portion 81 having a long rectangular shape extending in the front-rear direction.

  The stage portion 81 is an area where the pachinko ball B mounted on the stage portion 81 moves in the middle of dropping and has a plurality of holes 812 (four in this embodiment). The hole 812 has a rod-like obstacle 83 that can be moved in and out of the stage portion 81.

  The obstacle 83 changes the advancing direction of the pachinko ball B when it hits the pachinko ball B flowing down on the stage portion 81 when the obstacle 83 exits from the hole 812, and reciprocates up and down and is moved to a predetermined position. Stop if necessary. The hole 812 is hereinafter referred to as an obstacle in / out hole. In addition, the lift, which is the distance that the obstacle 83 rises, corresponds to the thickness of the stage portion 81 in this embodiment.

  Under the stage portion 81, as shown in FIGS. 5 to 11, there are a pair of intrusion execution means 84 for causing the obstacle 83 to appear and retract with respect to the obstacle appearance hole 812. The intrusion execution means 84 is in a locking relationship with the drum 841 as a cylindrical body having a plurality of protrusions 842 scattered on the outer peripheral surface, and the protrusion 842 of the drum 841, and the protrusion that rotates and abuts when the drum 841 rotates. The case body 82 has a heart-shaped cam 844 that rotates in accordance with 842.

  The protrusions 842 have relatively long protrusions and short protrusions, all of which have the same length, on the contrary, all of which have different lengths. You can choose from a variety of settings.

  The pair of drums 841 are juxtaposed in the longitudinal direction of the stage portion 81, as is apparent from FIGS. On each drum 841, a pair of the heart-shaped cams 844 are arranged in parallel with each other in parallel with the drum 841 while being separated from each other on the same axis.

  Further, the obstacle 83 is in a state of hanging from the stage portion 81 on the heart-shaped cam 844, and the lower end of the obstacle 83 is always in contact with the heart-shaped cam 844. Although illustration is omitted for the sake of simplicity, the obstacle 83 is configured to reciprocate up and down, but does not fall out or escape from the obstacle in / out hole 812.

  The drum 841 has a rotation shaft 841a connected to a drive shaft (not shown) of the stepping motor 24 (see FIGS. 12 to 14), and rotates clockwise or counterclockwise together with the rotation shaft 841a according to the rotation of the stepping motor 24. It is rotated clockwise. When the drum 841 is rotated, the heart-shaped cam 844 is pressed by one of the protrusions 842 of the drum 841, so that the heart-shaped cam 844 rotates in the direction opposite to the rotation direction of the drum 841. The obstacle 83 that is always in contact appears and disappears with respect to the stage 8 while being guided by the obstacle appearance hole 812 of the stage portion 81 (see FIGS. 5 to 7).

  In order to enable the protrusions and recesses by any of the protrusions 842, the installation positions of the drum 841 and the heart-shaped cam 844, which are the constituent members of the protrusion / extraction means 84, the length of the protrusions 842, and when the drum 841 rotates. The position of the protrusion 842 that contacts the heart-shaped cam 844 with respect to the obstacle in / out hole 812 in the drum 841, the outline of the heart-shaped cam 844, and the like are determined. The rotating shaft 841a and the cam shaft 844a are supported by a bearing portion (not shown) provided as appropriate on the case body 82.

  The heart-shaped cam 844 is loosely fitted around the cam shaft 844a so that the cam body 844b can rotate around the cam shaft 844a in an eccentric state. That is, the cam shaft 844b is fixed to the case body 82 and does not rotate, but the cam body 844b rotates. Further, the cam body 844b is configured not to be displaced in the axial direction with respect to the cam shaft 844a.

  Since the cam body 844b is loosely fitted to the cam shaft 844a in an eccentric state, the heart-shaped cam 844 has no protrusion on the cam body 844b, that is, the protrusion 842 of the drum 841 is not in contact with the cam body 844b. At that time, the cam body 844b settles by its own weight at a position where it is naturally stabilized by gravity (see FIG. 8).

In the drawing, according to the rotational positions of a total of four heart-shaped cams 844, when no obstacle 83 protrudes from the stage portion 81 (see FIG. 7), only one protrudes (see FIG. 8). The length, number, and arrangement of the protrusions 842 of the drum 841 and the position of the heart-shaped cam 844 so that the case of two protrusions (see FIG. 9) and the case of four protrusions (see FIG. 10) are obtained. Although the case where the length of the obstacle 83 is set is illustrated, it is needless to say that the present invention is not limited to this.

  When four obstacles 83 protrude from the stage portion 81, the guide for facilitating winning to the starting port 5 installed near the downstream end of the stage portion 81 by the four protruding obstacles 83. A path G is established in the stage unit 81 (see FIG. 10). The guide path G formed by the four obstacles 83 may have a dimension between the obstacles 83 located on the side thereof larger than the diameter of the pachinko ball B. If it is smaller than the sphere B, it is possible to prevent the pachinko sphere B from falling out of the sphere B, and it is preferable because it is easier to win the starting port 5 more reliably. In this embodiment, the guide path G is formed when the longest protrusions 842L (only two protrusions 842L are shown in the drawing, although there are actually many) are in contact with the four heart-shaped cams 844. It is like that.

  When the passing ball detection sensor 19 detects that the pachinko ball B has passed through the start port 5, the drum 841 is positioned at a position suitable for projecting four obstacles 83 from the stage portion 81 by adjusting the driving of the stepping motor 24. Is controlled to form a guide path G. When the guide path G is formed on the stage portion 81, the pachinko ball B is easy to win continuously from the start port 5. The position in the rotation direction of the drum 841 when the guide path G is formed is referred to as a reference position for convenience.

  As described above, the pachinko gaming machine 1 employs the stepping motor drive adjustment system S that drives the stepping motor 24 so that the obstacle 83 appears and disappears on the stage portion 81. The stepping motor drive adjustment system S will be described in the description of control described later.

  12, the pachinko gaming machine 1 includes a power supply device 29, a main control device 30 that controls the entire gaming machine, and a pachinko gaming machine based on a command signal output from the main control device 30. Based on a command signal output from the main control device 30 and a sub-control device 32 including a sound control device that controls a sound control device such as a lamp control device and loudspeaker (speaker) for controlling the lamp 1 and other electrical decorations. The drive control device 33 as a control unit that controls the drive of the stepping motor 24 that is a drive unit, lamps and other electrical decorations that operate based on command signals output from the sub-control device 32, amplifiers, mixers, speakers, and the like The sound generation device and other effect device 34 for performing other effects.

  The main control device 30 and the sub control device 32 are respectively provided with a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) (not shown). (Only those necessary for explanation are shown.)

  In order to drive the stepping motor 24 via the drive control device 33, an input signal from the passing ball detection sensor 19 is input to the CPU of the main control device 30 via an input interface (not shown).

  The drive control device 33 includes the stepping motor drive adjustment system S. The stepping motor drive adjustment system S controls the output of the stepping motor 24 and the rotation direction based on a command signal output from the CPU of the main controller 30 via an output interface (not shown).

The rotation direction of the drum accompanying the rotation of the stepping motor 24 is either clockwise or counterclockwise, alternately rotating at a predetermined interval, or alternately clockwise or counterclockwise at a predetermined angle. It may be a turn that rotates. How to operate depends on the program to operate the stepping motor drive adjustment system S. In short, when a predetermined condition is met during the game (when the pachinko ball B enters the start port 5 as described above), the stepping motor 24 rotates or turns the drum 841 at a predetermined direction and angle. Then, the guide path G is operated to form on the stage.

  The command signal for starting the operation of the stepping motor 24 or controlling the rotation direction is, for example, an appropriate handle operation detection sensor 10a for detecting that the handle 10 is operated when the handle 10 is operated, or a passing ball detection. This signal is output based on an input signal from the sensor 19 to the CPU.

  The stepping motor 24 is driven after a while after the player operates the handle 10, and the obstacle 83 appears and disappears irregularly with respect to the hole 812 via the drum 841 and the heart-shaped cam 844.

  Specifically, while the handle 10 is being operated by the player, the drum 841 is rotated by the stepping motor 24, and the heart-shaped cam 844 receives the pressing force of one of the protrusions 842 of the drum 841 so that the heart cam 844 rotates in the direction of rotation of the drum 841. The obstacle 83 that rotates in the opposite direction and is in contact with the heart-shaped cam 844 is pushed up onto the stage 81 from the obstacle in / out hole 812 (see FIGS. 5 to 7).

  However, when the cam main body 844b of the heart-shaped cam 844 does not contact any one of the protrusions 842, the cam main body 844b rotates clockwise or counterclockwise to a position where it naturally stabilizes due to gravity and settles with its own weight (FIGS. 5 and 5). 8). The obstacle 83 does not protrude from the stage portion 81 at the position where the weight is settled.

  However, since the stepping motor 24 is driven while the handle 10 is being operated, the obstacle 83 protrudes from the stage portion 81. Therefore, the obstacle 83 repeatedly appears and disappears with respect to the stage unit 81 while the player operates the handle 10.

  Note that the game control program and other programs related to the pachinko gaming machine 1 are installed in the ROM in an executable file format, and the functions and processing procedures of the embodiment according to the present invention include a bus and a memory (not shown). It is implement | achieved by being read by the main control apparatus 30 via.

  These programs can be recorded on a computer-readable recording medium (for example, a ROM (Read Only Memory), an MO (Magnet Optical), a CD (Compact Disk), an FD (FLEXIBLE Disk), or the like).

  As shown in FIG. 12, the power supply device 29 converts an AC voltage (AC24V) supplied from the outside by a power plug into a plurality of types of DC voltages, and then controls the main control device 30, the sub-control device 32, and the drive control device 33. , Supplied to the rendering device 34 and the like.

  Then, when the pachinko ball B passes through the start port 5, the passing ball detection sensor 19 detects the pachinko ball B, and the stepping motor drive adjustment system S causes the four obstacles 83 to protrude to the stage 8, and thereby the start port 5 is programmed to control the rotation of the stepping motor 24 so that a guide path G for guiding the pachinko ball B can be established.

  Such a stepping motor drive adjustment system S will be described with reference to FIG. 13 which is a system configuration diagram thereof, FIG. 14 which shows an electric circuit according to the system, and the above-described drawings.

  The stepping motor drive adjustment system S is controlled by a program stored in the ROM of the main controller 30 in order to operate the system S.

  When an input signal from the passing ball detection sensor 19 is input to the CPU of the main controller 30 via an input interface (not shown), a start signal is started from the CPU of the main controller 30. The start signal is converted into a pulse signal by the controller 33a, converted into a motor drive current by a driver 33b also included in the drive control device 33, and the stepping motor 24 is moved (see FIG. 13).

  Further, as can be seen from the electric circuit of FIG. 14, when the signal output from the CPU of the main control device 30 goes to the transistor 40, the current of the specific voltage of the power supply device 29 flows to the transistor 40 and is connected to the ground. The stepping motor 24 rotates.

  In order to ensure the guide path G, the position of the drum 841 (the drum rotation shaft 841a) is detected by the rotation angle detection sensors 27a and 27b (see FIGS. 12 and 14). Then, when the output signals of the rotation angle detection sensors 27a and 27b are input to the CPU of the main controller 30, the pachinko ball B wins the starting port 5 and forms the guide path G, and the drum 841 is used as the reference. Control suitable for returning to the position is performed.

  Next, the flow until the guide path G is established in the stage unit 81 by the obstacle 83 will be described with reference to the flowchart in FIG.

  In step (hereinafter referred to as S) 1, the handle 10 is operated. The stepping motor 24 is driven by the operation of the handle 10.

  In S <b> 2, the drum 841 of the appearing and executing means 84 is rotated by driving the stepping motor 24.

  In S3, it is determined whether or not the start opening 5 has been won. If the determination is affirmative, the process proceeds to S4. If the determination is negative, this routine is repeated until a positive determination is made.

  In step S4, the stepping motor 24 is rotationally controlled by the stepping motor drive adjustment system S so that the two drums 841 come to the reference position. If a positive determination is made in S4, the process proceeds to S5. If a negative determination is made, this routine is repeated until a positive determination is made.

  In S5, the stepping motor 24 is stopped, and the two drums 841 come to the reference position.

  In S6, it is determined whether or not a predetermined time has elapsed since S3, and the stepping motor 24 is stopped until the predetermined time has elapsed. While the stepping motor 24 is stopped, the guide path G is established. If an affirmative determination is made, the process proceeds to S7, and if a negative determination is made, this routine is repeated until an affirmative determination is made. The predetermined time here is, for example, the time until the electric tulip 11 is opened and closed.

  In step S7, the stepping motor 24 is driven again. By the driving, the obstacle 83 repeats the operation of appearing and retracting with respect to the stage unit 81.

Next, the function and effect of the pachinko gaming machine 1 configured as described above will be described.
According to the pachinko gaming machine 1, when the pachinko ball B rolling on the stage unit 81 hits the obstacle 83, its progress is changed. Since the obstacle 83 appears irregularly, the player does not know when and where the pachinko ball B rolling on the stage unit 81 hits the obstacle 83. For this reason, the direction in which the pachinko ball B flows down cannot be accurately predicted on the stage portion 81. Therefore, an unprecedented production effect can be expected.

  Further, it is difficult for the player to predict which projection 842 hits the heart-shaped cam 844 at which point. For this reason, since it is difficult for the player to determine which obstacle 83 appears or disappears, the interest increases accordingly.

  Further, when the pachinko ball B wins the start opening 5, four obstacles 83 project and establish the guide path G, so the pachinko ball B flowing down on the stage portion 81 is guided to the guide path G, and the start opening Facilitating winning 5

  It should be noted that by changing the shape of the cam, it is possible to cause the obstruction 83, which is a follower (driven side), to perform a specific operation according to the theme of the pachinko gaming machine 1. For example, by changing the heart shape to an egg shape, the operation of the obstacle 83 along another theme can be intended. In addition, since the contact side end of the obstacle with the cam is flattened to have a tappet shape, the contact range between the cam and the obstacle can be expanded, so the design range of the cam can be expanded.

  The plurality of protrusions 842 are exemplified by a mixture of long protrusions and short protrusions. However, when the protrusion lengths are different, the duration of the pressing force by the protrusions 842 acting on the obstacle 83 changes, and the protrusions 842 The longer the is, the longer the pressing time lasts. For this reason, the obstacle 83 is maintained on the stage 81 for a longer time.

  If the obstacle 83 is kept on the stage part 81 for a long time, the probability that the pachinko sphere B hits the obstacle 83 is increased, and the direction in which the pachinko sphere B flows down is changed. The pachinko sphere B flows down at a different speed, which is interesting.

A second embodiment will be described with reference to FIGS.
The difference between the second embodiment and the first embodiment is that the guideway G is established between the point that the obstacle becomes the windmill 83A and the time when the game state becomes a so-called probability variation state until the probability variation state ends. It is that it is done. Therefore, only the differences will be described.

  The difference between the windmill 83A and the rod-shaped obstacle 83 of the first embodiment is that a windmill portion 830 having a plurality of blades 833 is provided in the upper half of the obstacle 83. The drum 841 and the heart-shaped cam 844 of the intrusion execution means 84 are formed and arranged so that the guide path G is established by the four windmills 83A (only one is shown in the drawing). Note that the hole 812 may be bottomed.

  FIG. 18 shows a flow chart corresponding to FIG. 15 according to the first embodiment. Here, the flowchart of FIG. 15 according to the first embodiment differs from the flowchart of FIG. 18 according to the second embodiment in the formation time of the guide path G. It is formed to protrude from the obstacle in / out hole 812, and when the probability variation state ends, the four windmills 83A are housed in the obstacle in / out hole 812 and are not formed.

  That is, FIG. 18 is different from FIG. 15 in determining whether or not S32 in FIG. 18 resulting in S3 in FIG. 15 has changed in probability, and S62 in FIG. 18 similarly reaching S6 in FIG. It is only the point which becomes the step which determines whether the probability fluctuation | variation was complete | finished. Therefore, the same steps are the same as the other steps in FIG.

  In the case of the second embodiment, the pachinko sphere B rotates the vane plate 833 of the windmill 83A, so that the progress of the pachinko sphere B is changed. In addition, an unprecedented game mode can be enjoyed by turning the windmill on the stage portion 81. Further, since the guide path G is established during the probability variation, the pachinko ball B flowing down on the stage portion 81 is guided by the guide path G and facilitates winning at the start port 5.

A third embodiment will be described with reference to FIGS. 19 and 20.
The third embodiment differs from the first and second embodiments in that the obstacle is a triangular eccentric cam 83B, the absence of the heart-shaped cam 844, and the eccentric cam 83B being rotated by the protrusion 842 of the drum 841. It is a point to do. Therefore, only the differences will be described.

  When the protrusion 842 of the drum 841 is not in contact with the eccentric cam 83B, the eccentric cam 83B is settled by its own weight at a position where the eccentric cam 83B is naturally stabilized by gravity, and does not protrude onto the stage portion 81. Further, when the protrusion 842 comes into contact with the eccentric cam 83B, it receives the pressing force of one of the protrusions 842 depending on how the drum 841 rotates, and protrudes onto the stage portion 81 (see FIG. 19). Then, the eccentric cam 83B is rotated by the protrusion 842 of the drum 841, and when the four eccentric cams 83B all project on the stage portion 81, the guide path G is established by the four eccentric cams 83B.

In the case of the third embodiment as well, as the first and second embodiments, since the guide path G is established, the pachinko ball B flowing down on the stage portion 81 is guided by the guide path G, and it is easy to win the start opening 5. To do.
Because it is in an eccentric state, the eccentric cam that performs its own movement is an obstacle, so the movement as an obstacle can be changed and the interest will be enhanced.

Example 4 will be described with reference to FIG.
The fourth embodiment is different from the first embodiment in that, for example, a sponge, a spring, or other elastic member 831 is positioned on the extension line of the obstacle 83 at the top 83 a of the obstacle 83 that exits from the obstacle in / out hole 812. It is in the point which was made to adhere to by adhesives etc.

In this manner, in addition to the operational effects of the first embodiment, when the pachinko ball B hits the sponge or other elastic member 831, an unexpected movement is caused to the pachinko ball B due to the elastic force of the elastic member 831. Become.
In the case of the fourth embodiment, as in the first to third embodiments, since the guide path G is established, the pachinko ball B flowing down on the stage portion 81 is guided by the guide path G, and the winning to the start port 5 is facilitated. To do.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the scope of the present invention.
For example, instead of having the guide path G formed when the pachinko ball B enters the start port 5, the pachinko ball B has won a passing gate (through chucker) that rotates a so-called sub-digital (not shown). Of course, the program may be programmed so that the guide path G is formed. In this case, in the flowchart of FIG. 15, S3 changes from “Did you win the starting gate?” To “Did you win the passing gate?”.

  By forming the case body 82 with a transparent member, the timing at which the obstacle moves up and down by the heart-shaped cam or / and the drum can be known. Then, since the timing of launching the pachinko ball B can be achieved, the interest of the player can be enhanced thereby. If the case body 82 is partially transparent rather than completely transparent, the heart-shaped cam 844 and a part of the drum 841 are visible to the player, which is different from the case where the entire case body 82 is visible.

  In addition, if the stage 8 is formed smaller than the in / out execution means 84 so that the pachinko ball B flowing down the stage 8 falls from the stage 8 and hits the heart-shaped cam 844 or the drum 841, Although it becomes difficult to enter, it is interesting to be able to change the direction in which the pachinko ball B flows down after falling from the stage 8.
