Description

  The present invention relates to a ball game machine, and particularly has a feature in a technique that enables an enlargement of a central device.

  In general, in a ball game machine, a game ball bulleted at the upper part of the game area flows down with various paths. And, as the flow path of the game balls is diversified, the behavior of the game balls does not become monotonous, and the player can always be expected to enter the entrance, and a high preference can be obtained. The flow path of the game ball is affected by the arrangement of various game members (such as obstacle nails, ball entrances (including winning entrances, passing gates, etc.), windmills, and attackers). Therefore, it is not desirable that the degree of freedom of arrangement of the various game members is restricted in order to make the game balls flow down more effectively in a limited game area. For this reason, a liquid crystal display screen having a size of about 4 to 6 inches and a center accessory set so as to surround the liquid crystal display screen and surrounding it are provided. A certain area width is ensured in the area, and a thing provided with a entrance is becoming mainstream (see Patent Document 1).

  However, considering the adoption of a large central device that enables a variety of gaming modes with excellent visibility, the area occupied by the central device in the gaming area increases, so the arrangement of game members other than the central device has great restrictions. receive. For example, when the right and left game areas of the central device are narrowed due to the enlargement of the central device, and a entrance and a windmill are arranged in the narrowed game region, the flow path of the game balls around these game members It is difficult to give various changes to the game, and the behavior of the game ball tends to be monotonous. In addition, if the entrance is located at the top of the game area (e.g., directly above the central device), the flow path of the game ball entering the entrance is shortened, so the entrance is below the game area. It is considered that the flow path can be predicted more easily than in some cases, and a player with high skill can aim at the entrance. In addition, since it is difficult to secure a flow path of game balls in the game area around the central device, it is necessary to cause the central device to introduce and derive game balls. Therefore, a technique for causing the game balls to flow down in the central device is important in maintaining and improving the preference. Accordingly, an object of the invention described in claim 1 is to enable an enlargement of the central device without impairing the preference.

A pachinko machine 1 according to an embodiment of the present invention is a fever machine or a model called a first type.
(Front structure of pachinko machine 1)
As shown in FIG. 1, a game board 2 is detachably mounted on the surface side of the pachinko machine 1. On the game board 2, a guide rail 3 (see FIG. 2) for guiding the shot hit is planted in a substantially arc shape, and an area partitioned by the guide rail 3 is a game area 4 (see FIG. 4). It is composed. The front of the game board 2 is covered with a glass plate 22 (see FIG. 9) as a transparent plate. The glass plate 22 is actually a double glass plate 22a, 22b, and the game area 4 is precisely formed between the inner glass plate 22a and the game board 2. The distance between the inner glass plate 22a and the game board 2 is set to 20 mm. The game area 4 is an area partitioned by the first rail member 3a, the second rail member 3b, the return rubber 3c, and the decorative member 3d (see FIG. 2). A game ball is guided to the game area 4 through the gap between the first rail member 3 a and the second rail member 3 b on the left half surface of the game area 4. A return rubber 3c is attached to the left top portion of the decorative member 3d so that the game ball is reflected to the center of the game area 4. In the present embodiment, the game area 4 is set by the first rail member 3a extending to the return rubber 3c and the second rail member 3b extending to the decorative member 3d. The game area 4 may be set in various configurations other than this, but the description thereof is omitted. A backflow prevention device 3e is provided at the upper left end.

  A starting entrance 7 that can be opened and closed is provided in the central portion below the central device 5, and an attacker 8 (also called a big prize device) is provided below the starting entrance 7. The attacker 8 is normally unable to enter the ball, but when the open / close plate 8a is tilted forward and the large winning opening (not shown) behind it is opened, it becomes extremely easy to win. When a game ball is received at the starting entrance 7, the special symbol displayed on the liquid crystal display board 5a (see FIG. 2) starts to change, and this is a specific display mode, for example, 777, which is the same three-digit number. When the stop display is made, a special gaming state is established, and the attacker 8 is opened a predetermined number of times (for example, 16 times) to accept the game ball. Further, the entrance 9 to the entrance 12 are collectively provided on the left and right of the attacker 8, and together with the start entrance 7 and the attacker 8, the entrance group N (see FIG. 2) is configured. The area in which the entrance group N can be arranged is lower than the lower end of the center accessory 6 that is a component of the central device 5, and with respect to the height L of the game area 4 (see FIGS. 3 and 4). The height is about one third (27% in FIG. 3). Here, each of the entrances 7 to 12 constituting the entrance gate group N is used as a trigger for paying out a prize ball. At the lowermost part of the game board 2 (the lowest point of the second rail member 3 b), an out port 13 for receiving an out ball and wind turbines 14 are provided at the lower left and right of the center accessory 6.

  Further, a glass frame 15 covering the front surface of the game board 2 is provided on the front frame 16 so as to be freely opened and closed. Immediately below the game board 2, an upper tray portion 17 that can be opened and closed by a hinge (not shown) and a lower tray portion 18 that cannot be opened and closed are located, and these are mounted on the front frame 16. A speaker 20 is provided on the lower left side of the upper plate portion 17 to generate sound effects according to the gaming state. In addition, a launching handle 21 is provided on the right side of the lower plate part 18, and a game ball launching device unit 147 (see FIG. 14) that ejects a game ball supplied from the upper plate part 17 to the game area 4. It is connected, and can play a game ball with strength according to the degree of the turning operation of the launch handle 21. The firing handle 21 is provided with a touch switch 21a, and a firing stop switch 21b is provided near the upper left of the firing handle 21.

(Dimensional relationship between game area 4 and central device 5)
Although it is possible to dispose the entrance into the game area 4 above the central device 5, in this embodiment, the entrance of the game ball is an obstacle, so generally no entrance is provided. The central device 5 includes a 5-inch size liquid crystal display panel 5a (sometimes referred to as a special symbol display device because it displays a special symbol), and a center accessory 6 ( 6 to 12), a special symbol control board 170 (see FIG. 15), and the like, and has a horizontally long shape. The outer peripheral shape of the center accessory 6 is a horizontally long substantially oval shape or substantially oval shape (the aspect ratio which is the ratio of the maximum height to the maximum width is approximately 1.1 to 1.7, preferably approximately 1.3 to 1. 7, particularly preferably 1.3 to 1.4). The outer dimensions of the center accessory 6 may be appropriately changed depending on the distribution conditions of the game balls. It is possible to replace the liquid crystal display panel 5a with another display body such as a large CRT or LED. Further, in the present embodiment, the central device 5 is configured to include the center accessory 6, but the center accessory 6 is not necessarily included.

When the large center accessory 6 is mounted on the game board 2, the area of the game area 4 remaining in the periphery of the central device 5 is reduced. That is, as shown in FIG. 2, the width of the center accessory left and right sphere passage region J, which is the width of the game region 4 on the left and right of the center accessory 6, is W ₁ = 33 mm (hereinafter, center agent left and right sphere passage region width W ₁ In addition, the height of the guide Ryukyu receiving area H ₁ of the game area 4 above the center accessory 6 is about 70 mm.

  For example, assuming that the entrance is arranged on the left and right of the central device 5, for example, in the vicinity of the center accessory left and right sphere passage area J (see FIG. 2), the single entrance is usually about 20 mm in width of the ball receiving portion. Including the mounting base, the full width of the entrance is about 40 mm, making it difficult to install the entrance. Therefore, even if the entrance is attached from the back side of the game board 2 and only the base of the entrance is protruded from the front side of the game board 2, the width of the base is about 20 mm. The remaining space is about 13 mm. Eventually, although it is possible to place obstacle nails and entrances, it is difficult to let the game balls flow down.

  In addition, although it is possible to install a entrance into the game area 4 above the central device 5, a cage (not shown) that guides the game ball that has entered the entrance to the bottom on the back side of the game board 2 is provided. The rear part of the central device 5 (the case of the liquid crystal display panel 5a, the display control board, etc.) must be avoided, and the installation is possible but may not be preferable. Therefore, it is preferable that the central device 5 be arranged as high as possible above the game area 4 in order to ensure the freedom of arrangement of the entrance and the attacker below the game area 4. If it is arranged above, the effective space below the game area 4 is expanded, but there is a relation that the entrance cannot be arranged above. Therefore, a design that takes these relationships into consideration is desirable.

Furthermore, have fallen in FIGS. 10 and above the center won game 6 in 11 is disposed a guide portion 64 comprising a plurality of failure (nails etc.), induction gutter ball socket in the width of the area width W ₂ The game balls are configured to easily enter the ball inlets 50a and 50b. The game balls that have entered the ball entrances 50a and 50b flow down onto the stage 44 via the warp rods 52a and 52b (see FIGS. 7 and 8) and are collected above the start entrance 7 so The possibility of entering the ball opening 7 is increased. By the way, in the conventional ball game machine (not shown), in order for the game ball to be launched at a position where it can easily enter the starting entrance (not shown), the player uses the firing force of the launching device (not shown). Although it is adjusted and fired, even if it is adjusted (fixed) so that the firing force of the launching device (not shown) is constant, there is a possibility that the launch force may be contrary to the adjustment due to variations in the launch force. Therefore, in some cases, a game ball (not shown) is launched at a position where the possibility of entering the starting entrance (not shown) is extremely low against the player's will, and there is a risk of causing a disadvantage to the player. is there. In contrast, in the pachinko machine 1 of this embodiment, if it is a game ball is launched into the game region 4 relatively in the wide-induced gutter ball socket width of the region width W ₂ of width, as the game ball with the aforementioned Since the balls are collected at the ball entrances 50a and 50b, the game balls can easily enter the ball entrances 50a and 50b, and as a result, the possibility of entering the start entrance 7 is increased. Therefore, there is an excellent effect that the possibility that the variation of the firing force of the launching device (not shown), the skill of the player, etc. will affect the entry of the game ball into the start entrance 7 becomes extremely low.

The dimensional relationship of the game board 2 will be described with reference to FIGS. The relationship of dimensional surfaces between the central device 5 and the surrounding game area 4 will be described with reference to FIG. Vertical distance of _{H 2} from the top of the central unit 5 to the top of the game area 4 is 67 mm, the vertical distance _{H 3} from the apex of the central unit 5 to the apex central nail 34 mm, the height _{H 4} of the center won game 6 to 221mm Is set. Furthermore, induction gutter ball socket area width _{W 2} is 90 mm, the horizontal distance _{W 3} between the left and right ends vertices nail in the upper region of the center won game 6 top 151 mm, inlet 66a, 66b (see FIGS. 10 and 11) each width _{W 5} is 14mm, the inlet 66a, 66b (FIGS. 10 and 11 refer) horizontal distance _{W 6} is 59mm left and right upper nail, the width _{W 7} of the center won game 6 309 mm, center won game lateral sphere some upper region width of the passage area width _{W 1} is left width _{W 8} is 33 mm, the right width _{W 9} is set to 32 mm. Windmill 14 width of the left and right areas (see FIG. 2) is disposed in the left width _{W 10} is 47 mm, the right width _{W 11} is set to 46 mm. Expanding the maximum transverse width _{W 12} of the starting ball entrance opening 7 is 49 mm, the normal width _{W 13} is set to 13 mm. Further, from the horizontal line S passing through the lowest point of the first rail member 3a, the uppermost part of the center accessory 6, the central horizontal line of the liquid crystal display panel 5a, the starting entrance vertex, and the lowest point of the center accessory 6 are passed. A horizontal line, a horizontal line indicating the center height of the attacker 8, the top point of the entrance 12 and the vertical distances H ₅ , H ₆ , H ₇ , H ₈ , H ₉ , H ₁₀ , H to the top of the entrance 11 ₁₁ are set to 329 mm, 201 mm, 93 mm, 108 mm, 48 mm, 67 mm, and 91 mm, respectively. Maximum transverse width _{W 14} of the game region 4 is set to 394Mm. A height H ₁₅ assuming a screen of a 10-inch liquid crystal display panel 5a indicated by a two-dot chain line is 147 mm, a width W ₁₅ is 207 mm, a height H ₁₆ assuming a screen of the 8-inch liquid crystal display panel 5a is 117 mm, and W ₁₆ is It is set to 166 mm.

Moreover, when the area measurement (on CAD) of the game area 4 is performed, it becomes about 123,988 mm ² . The area of a perfect circle whose diameter is the vertical dimension (L = 396 mm) of the game area 4 is about 123,163 mm ² and is almost equal to the result of the area measurement. Therefore, in the embodiment, the area of the game area 4 is the diameter L It is calculated by approximating with a perfect circle. The measurement dimension L is a vertical distance from the lowest point to the highest point of the game area 4. Moreover, the area of each member in the embodiment is as follows (see FIG. 5).
Central device 5 (Large) Approximately 58,463mm ²
Central device (A) (slightly large) Approximately 37,416mm ²
Central device (B) (slightly large) Approximately 30,426mm ²
The area of the central device in (A) is calculated assuming that the scale of the central device 5 is 0.8 times (area ratio 0.64). However, the approximate dimensions of each part of the warp hooks 52a, 52b are naturally determined based on the diameter of the game ball and the wall thickness of the wall, and it is necessary to secure a dimension through which the game ball can pass. It is considered that the vertical and horizontal dimensions and the external dimensions of the ornament covering the bag are not significantly different from those of the central device 5. Therefore, when the central device (A) is used, it is considered that the actual projected area of the central device is actually larger than the calculated value. From the above, in the case of the central device 5, the ratio of the area of the central device 5 to the gaming area 4 at that time is 47%. In the case of the central device (A), the ratio of the area of the central device 5 to the game area 4 at that time is 30%. The area ratio of the central device (B) is 25% (about 4: 1), and the area is the minimum area. (C) is an extension of the central device 5 to the full left and right area, but the area is not measured. As described above, the central device 5 is characterized by occupying approximately 25% (1/4) or more, preferably approximately 30% or more, particularly preferably approximately 47% or more of the surface area of the game area 4. Here, the area means a projected area. Playfield central horizontal line Y ₁ of the game region 4, in the embodiment, substantially coincides with the central horizontal line Y ₂ of the liquid crystal display panel 5a. Ball entrance opening group N are collectively arranged so as to avoid the central unit 5 to the lower region than playfield central horizontal line Y _1. That is, the height of the area where the entrance group N is arranged is the height from the lowermost part of the game area 4 to the lower end of the center accessory 6, and the left and right of the arranged area are full.

In this embodiment, the central device 5 is used. However, when the central device (A) is used, the area occupied by the central device 5 is reduced, and there is room left and right or above the central device 5. Will increase. For example, in (A), a display body of about 8 inches, which is slightly larger than a generally adopted size (4 to 6 inches), is fully used, and the center accessory 6 of the embodiment is simply reduced in size accordingly. It corresponds to a case. In this case, if the width dimension of the center accessory left and right sphere passage area width W ₁ (area where the game ball can flow down) is calculated based on the difference in screen width dimension of FIG. 3, (W ₁₅ −W ₁₆ ) / 2. = (207.4-165.9) /2=20.75mm, increasing by about 20mm to the left and right respectively. Therefore, since the center won game lateral sphere passing area width _{W 1} of the central unit 5 is about 33 mm, each of the width of the lateral area is approximately 53mm (= 33 + 20). When a single entrance (not shown: for example, a small one with a width of about 20 mm) is arranged in this area, about 16.5 mm (= (53-20) on both sides of the entrance (not shown). / 2) can be secured, but since the diameter of the game ball is 11 mm, the path of the game ball deviating from the entrance is only 2.75 mm (= (16.5-11) / 2) left and right. Can not. For this reason, the game ball deviating from the entrance can only flow down almost directly, and it is difficult to give a sufficient change to the behavior of the game ball to enhance the preference. Furthermore, since the total number of entrances is stipulated in the game rules, and the total number of entrances (total number of winnings) must be maintained above the specified number, the number of entrances with the increase in the size of the central device 5 Cannot be reduced easily. Therefore, in order to make the central device 5 larger than the current state without reducing the total number of entrances, it is essential to solve the problem of the entrance entrance arrangement. For this reason, no entrance is installed in the center accessory left and right ball passage area J, and the entrance group N is concentrated and arranged in the area as described above. In addition, according to the current game rules, the total number of balls entered is defined to be 5 or more in a normal gaming state in which the movable accessory does not operate, and the number of starting ports is one third ( It must be greater than or equal to the decimal point. In the present embodiment, the total number of entrances is five and the number of starting ports is one, which satisfies this rule. If the total number of entrances is more than that, it may be necessary to appropriately change the placement of entrances.

FIG. 4 shows the projection plane of the game area 4 with diagonal lines. In the figure, T ₁ is a central vertical line of the game area 4, and T ₂ is a central vertical line of the accessory arrangement. Both center lines do not coincide with each other, T ₂ is deviated to the right with respect to T ₁ , and the offset amount is set to 4 mm. A horizontal line S indicates the lower limit of the game area 4.

The diagonal lines in FIG. 5 indicate the projection plane of the central device 5 with diagonal lines. The projection surface of the central device (A) is indicated by a two-dot chain line curve. In the case of FIG. 5, the possible range of the height M of the area where the entrance gate group N can be arranged is approximately 25% to 60% of the height L (see FIG. 3) of the game area 4 in the case of the central device (B). In the case of the central device (A), it is approximately 25% to 55%, and in the case of the central device 5, it is approximately 25% to 35%. Also, if the central unit 5, the possible range of the percentage of the maximum transverse width W ₁₄ of the center won game lateral sphere passing area width W ₁ of the game area 4 _(see FIGS. 3 and 4) is approximately 0% to 25% In the case of the central device (A), it is generally 0% to 15%, and in the case of the central device (B), it is generally 0% to 10%. In the above, 0% means that the central device 5 is substantially biased to the left and right regions as illustrated in the case where the central device 5 is biased to one side (narrow side thereof) or as illustrated in the central device (C) of FIG. This is a case of expansion.

(Configuration of central device 5)

By the way, the depth of the central device 5 is set to such a width that the behavior of the game ball on the stage 44 is appropriate. That is, as shown in FIG. 9, for its depth is set maximum height of the center won game 6 against (corresponding to H ₄ in FIG. 3), approximately 50% (approximately 11cm). The range is approximately 5 cm to 20 cm, preferably approximately 10 cm to 15 cm, and particularly preferably approximately 11 cm to 12 cm.

  A safe ball assembly cage 118 installed on the back of the game board 2 is disposed on the back side of the inclined plate 33. All game balls that have passed through the entrance holes 45 to 47 flow into the safe ball assembly cage 118. The safe ball assembly cage 118 has a structure in which game balls that have passed through a ball hole 79 formed in the game board 2 in communication with the starting ball slot 7 and the like flow in.

The uppermost surface of the center won game 6 formed induced gutter ball socket area K (see FIGS. 10 and 11), it is one configured from a portion of a length corresponding to the induction gutter ball socket area width W ₂ It is. As shown in FIGS. 7 and 8, a pair of ball inlets 50 a and 50 b are provided on the upper portion of the decorative portion 31 with a space left and right, and the ceiling plate of the frame 32 is provided at the pair of ball inlets 50 a and 50 b. 35 and a pair of warp rods 52a and 52b communicating with the ball inlets 50a and 50b disposed along the wall plates 34a and 34b are connected. The warps 52a and 52b are bent into an L shape inside the center accessory 6 and extend horizontally outward, and further bent into an inverted L shape at the back and extended vertically downward, facing the large opening 36. The wall plates 34a and 34b (see FIG. 8) communicate with a pair of ball outlets 53a and 53b provided at the lower back corners, respectively. That is, the warp rods 52a and 52b extend along the upper surface of the large opening 36 on the back side of the mounting substrate 30 and reach the ball outlets 53a and 53b. Further, start passage openings 54 a and 54 b are provided at the left and right ends of the decoration portion 31, and the game balls that have flowed into the start passage openings 54 a and 54 b are opened to the left and right lower ends of the decoration portion 31.

Small inclined surfaces 51a and 51b (see FIG. 10) inclined downward inward are formed at the outer end portions of the ball inlets 50a and 50b, so that the guide to the warp rods 52a and 52b is smooth. Induced gutter ball socket area width W _2, the two spheres inlet 50a, represents the dimension obtained by adding the width of the opening width and the partition portion 63 of 50b. Sphere inlet 50a as viewed from the plane in the exemplary embodiment, each opening width 22mm of 50b, the width of the partition part 63 is 46 mm, inductive gutter ball socket area width _{W 2} is set to 90 mm. In addition, when providing _two ball | bowl inlets 50a and 50b like this embodiment, it is thought that the minimum dimension of the induction | guidance | derivation Ryukyu socket area | region width W2 will be 24 mm. This dimension value is obtained by setting the opening widths of the ball inlets 50a and 50b to 11 mm (22 mm in total) and the width of the partition part 63 to 2 mm, and adding them up. In general, since a game ball is manufactured with a positive / negative tolerance (for example, 0.05 mm) on a diameter of 11 mm, the opening widths of the ball inlets 50a and 50b are set slightly larger than 11 mm in consideration of the positive / negative tolerance. Moreover, 2 mm of the width | variety of the partition part 63 mentioned above is the minimum board thickness required in order to perform resin molding favorably, when partitioning both the ball | bowl inlets 50a and 50b with one sheet | seat made from resin. Further, a normal symbol display device 60 is installed at the center of the decoration portion 31, and four holding lamps 61a to 61d are installed near the lower side thereof.

  As described above, by configuring the central device 5, the game ball B that has entered the ball inlets 50 a and 50 b passes through the warps 52 a and 52 b and is discharged from the ball outlets 53 a and 53 b to the stage 44. Flows out. Most of the game balls B pass through the stage 44 and are discharged out of the center accessory 6 and fall into a region where the starting entrance 7 and entrances 9 to 12 are present (see FIG. 2). On the other hand, the game ball B that has entered the start passage openings 54a and 54b is detected by the normal symbol operation gate passage detection switches 55a and 55b and falls to the game area 4 below. In this embodiment, when the game ball B is detected by the normal symbol operation gate passage detection switches 55a and 55b, the number of the normal symbol display device 60 is variably displayed, and the stopped number is a predetermined number (for example, 7). Then, the blade member of the starting entrance 7 is configured to be opened for a predetermined time (for example, 0.5 seconds). As a result, the player always has a sense of expectation that the game ball B on the stage 44 will enter the start entrance 7 and can always enjoy a thrilling game.

(Configuration of guide section 64)
The guide part 64 is demonstrated with reference to FIG.10 and FIG.11. The guide portion 64 is composed of a plurality of obstacle nails. The central portion of the guide portion 64 is composed of an outflow restricting portion 65 composed of three nail groups arranged in a mountain shape. The outflow restricting portion 65 is disposed so as to surround the upper portion of the guide Ryukyu receiving region K, and has a triangular shape. A space is formed, and in the outflow restricting portion 65, introduction ports 66a and 66b (nail gaps) for introducing game balls into the guide Ryukyu receiving region K are formed. Hindered guide portion 64 that game balls flow down to the center won game lateral ball passage region width W _1, it can be secured interest for games by increasing the probability of introducing a sphere inlet 50a, to 50b. Further, in order to bring the game ball to the center, obstacle nails are also arranged on both sides of the outflow restricting portion 65 so as to be symmetrically inclined, so that the game ball is smoothly guided to the ball guide surfaces 62a and 62b. Due to the action of these ball guiding surfaces 62a and 62b, there is a possibility that the game ball slides down here and is reflected by the obstacle nail near the start passage openings 54a and 54b and enters the start passage openings 54a and 54b. .

  The operation of the guide Ryukyu receiving area K will be described with reference to FIGS. There is an effect that the game ball that has once reached the guide Ryukyu receiving area K through the introduction ports 66a and 66b is unlikely to flow out of this area. By the way, conventionally, in addition to the problem of variation in the launching force of the game ball launcher (not shown), it becomes difficult to enter the starting entrance 7 with the increase in the size of the central unit 5, The problem of becoming monotonous has arisen. That is, if an excessively large number of game balls flow down the left and right sides of the game area 4 while avoiding the central device 5, the game balls are far away from the start entrance 7 and are difficult to enter the start entrance 7. Although it is possible to arrange obstacle nails so that the game balls can easily gather at the start entrance 7, the game balls are traversed from the left and right of the central device 5 toward the start entrance 7. Therefore, the behavior of the game ball tends to be monotonous and unnatural. Therefore, in order to eliminate such inconvenience, it is possible to give a variety of behavior to the game balls in the central device 5 by guiding more game balls through the central device 5 to the entrance gate group N. Therefore, it is possible to prevent the behavior of the game ball from becoming monotonous.

(Operation of this embodiment)
When the player holds the firing handle 21 and rotates it, a ball game is played. The game ball shot on the game board 2 falls from the upper side to the lower side in the game area 4 while the course is changed by an obstacle nail or a windmill. A part of such game balls detours around the center accessory 6 or passes through the start passage openings 54 a and 54 b of the center accessory 6, and a part thereof falls into any entry entrance of the game area 4. The prize is won, and the rest becomes an out ball and is discharged to the back side of the game board 2. On the other hand, some game balls flow into the warp rods 52a and 52b from the ball inlets 50a and 50b of the center accessory 6, and flow into the stage 44 through the ball outlets 53a and 53b. The game ball that has flowed into the stage 44, for example, rolls on the inclined plate 33 while colliding with the obstacle protrusion 40 and changing the course, and some of the game balls flow into the entrances 41 to 43 and enter the entrance holes 45 to 45. 47 passes through and is collected by the safe ball assembly cage 118 and processed as a winning ball. The game balls that have not flowed into the entrances 41, 42, 43 fall from the inclined plate 33, return to the game area 4 from the stage 44, and enter any entrance of the game area 4, Or it becomes an out ball and is discharged to the back side of the game board 2. In this way, in addition to the game area 4 formed on the front surface of the game board 2, the stage 44 is provided in the center accessory 6, so that the area for the game is widened as a whole, and the preference of the ball game is increased. Can be improved.

  Further, in a state where no game ball is won at the starting entrance 7, the lottery process (whether or not is judged) is not executed in the electronic control device 160, and the result is not displayed. When a game ball wins at the starting entrance 7, the special symbol starts to fluctuate, and the electronic control device 160 executes a lottery process (whether or not), and a special symbol indicating the result (win / fail) is displayed on the display unit 38. Is displayed. In the present embodiment, the special symbol is a nine-division display in which nine special symbols are displayed in a variable stop state at once. FIG. 19 illustrates a jackpot symbol. The attacker 8 is not released when stopped and displayed in a mode other than the specific display mode, and the special game is executed when the attacker 8 is stopped and displayed in the specific display mode (for example, 777). .

  Also, in response to the game ball passing through the normal symbol operation gate passage detection switches 55a and 55b, the normal symbol display device 60 starts to change the normal symbol, and this stops at a predetermined display mode, for example, the number 7 When displayed, the blade member of the starting entrance 7 is opened (widened) for a predetermined time (for example, 0.5 seconds), the probability of entering the starting entrance 7 is increased, and the blade member is increased as the predetermined time elapses. On the other hand, when the stop display is performed in a manner other than the predetermined display mode, the blade member does not open and the probability of entering the starting entrance 7 remains unchanged. In place of the starting entrance 7, this can be replaced with a starting passage gate (not shown), and the special symbol can be changed and stopped due to the passage of the game ball.

  The above-mentioned special game is similar to a known pachinko machine called the first type, but will be described briefly. The opening / closing plate 8a (see FIG. 2) is tilted to make the attacker 8 very easy to win. Then, when about 30 seconds have elapsed after the attacker 8 is opened, or when the number of winning balls to the attacker 8 reaches 10, the open / close plate 8a is raised to close the open / close plate 8a. At this time, if any of the winning balls that have been opened this time has passed the V region (not shown) of the attacker 8, the attacker 8 is opened again and closed in the same manner as described above. When there is no game ball that has won a prize during the opening of the attacker 8 and has passed the V region (not shown), or when the number of opening of the attacker 8 reaches a specified number (16 in this embodiment), The attacker 8 is not reopened and the special game ends. According to the above-described embodiment, in the stage 44, there is an effect that a noticeable change can be given to the behavior of the game ball and visibility can be improved.

  A predetermined number of time-saving functions may be added depending on the type of jackpot after the jackpot. That is, the special symbol is shortened in the variation time, the regular symbol displayed on the normal symbol display device 60 is also shortened in the variation time, and when the normal symbol is hit, the opening time of the start entrance 7 is, for example, 4 Seconds are extended. The number of time reductions can be set according to various general techniques. For example, the number of time reductions can be made constant or can be changed according to conditions.

The safe balls are collected by the safe ball gathering box 118 ′ and processed as winning balls. In addition, the game balls that have not flowed into the entrances 41 ′ to 43 ′ return to the game area 4 ′ from the secondary game board 186 and enter any of the entrances in the game area 4 ′, or Thus, it is discharged to the back side of the game board 2 ′ (see FIG. 16).

  In this way, in addition to the game area 4 ′ formed on the front surface of the game board 2 ′, the secondary game board 186 is provided in the central device 5 ′ so as to be detachable (see FIG. 17). This area is widened, so that it is possible to improve the preference of the ball game, and the exchange is possible, so that the game can be interesting. In addition, a plywood auxiliary game board 186 is used to drive the obstacle nail 40 ′ as a game member and the entrances 41 ′ to 43 ′ are attached with screws, so that they are arranged on the game board 2 ′. The same gaming members as can be used. Therefore, it is not necessary to prepare a special game member for the auxiliary game board 186. Further, the obstacle nail 40 ′ can be bent and adjusted with, for example, a hammer, so that it is possible to improve the game preference on the secondary game board 186 by such adjustment.

(Second modification of the central device 5)
Next, a central device 205, which is a second modification in which a gaming device such as a prize opening device or a gaming member such as an obstacle projection is provided on the stage, will be described with reference to FIGS. In addition, the pachinko machine 201 of this form changes the stage structure of the center apparatus 5, makes it removable, and moves the position of a start winning apparatus to a stage. Accordingly, illustrations and descriptions of common parts are omitted as appropriate, and portions to be described are illustrated and described below. In the drawing, elements corresponding to those of the above-described embodiment are described by adding 200 to the same product number, and new numbers are assigned to new elements.

  As shown in FIGS. 19 to 21, a stage attachment hole 257 is provided in the floor 248 of the frame body 232, and the stage 244 is attached thereto. Specifically, as shown in FIG. 22, the edge of the stage mounting hole 257 has a stepped shape, and the stepped portion 258 of the stage 244 is fitted into the stepped portion and can be rotated around the pin 267. A rectangular locking piece 268 supports four places on the back, top, bottom, left and right of the stage 244. If the longitudinal direction of these locking pieces 268 protrudes to the stage 244 side, the stage 244 is fixed (the state shown in the figure), and if the locking piece 268 is rotated to remove the longitudinal direction from the stage 244, the stage 244 is removed. be able to.

  As shown in FIG. 21, on the upper surface side of the stage 244, an obstacle projection 240 as a gaming member and a start winning device 207 as a gaming device are installed. The start winning device 207 is a tulip-type winning device including a pair of blade members 207a. When the blade member 207a is opened, it becomes easy to win. In addition, as shown in FIG. 22, the stage 244 is provided with a ball hole 241 for dropping a game ball that has entered the start winning device 207 so as to guide the game ball that has won the start winning device 207. Are connected to the entrance hole 241. A drive unit 249 for opening and closing the blade member 207a is disposed on the back side of the stage 244.

  As shown in FIGS. 19 and 22, a central decorative portion 231 b, a left decorative portion 231 a, and a right decorative portion 231 c are arranged on the front side of the central device 205. The central decorative portion 231b, the left decorative portion 231a, and the right decorative portion 231c protrude from the front surface of the mounting board 230 (that is, the front surface side of the game board 202). The central decoration portion 231b is provided with a pair of ball inlets 250a and 250b, and warp rods 252a and 252b are connected to the ball inlets 250a and 250b. The other ends of the warp rods 252a and 252b are connected to ball outlets 253a and 253b provided in the frame body 232. The ball outlets 253a and 253b are opened toward the inside of the frame body 232, and the game balls that have flowed into the ball inlets 250a and 250b are guided by the warp rods 252a and 252b and are moved onto the stage 244 from the ball outlets 253a and 253b. leak.

  In the central device 205 of the pachinko machine 201, the stage 244 can be attached and detached by operating the locking piece 268 (see FIG. 22). Therefore, when changing the shape and function of the stage 244, the obstacle protrusion 240, the start winning device 207, etc., only the stage 244 needs to be changed. For example, the entire central device 205 or the frame 232 holding the stage 244 is changed. There is no need, and it is possible to eliminate inconveniences such as complication of design work and cost increase due to changes in them (such as the central device 205). Moreover, since the obstacle protrusion 240 and the start winning device 207 are arranged on the stage 244 installed in the central device 205 and the stage 244 is used as the second game area, the whole (formed on the game board 202). The effective space of the game area can be expanded (with the same game area as the conventional game area and the second game area described above). When a large variable display device is installed in a ball and ball game machine such as a pachinko machine, the effective space of the game area is reduced, so it is difficult to arrange game devices and game members, etc. It might be. However, if these are arranged on the stage as in the second modification, the game can be prevented from being adversely affected and the effective space can be expanded. Therefore, it is particularly effective when a large-sized variable display device is provided. It is. In addition, game devices and game members arranged in a ball game machine may be common to a plurality of models and may be different for each model. If some or all of the game devices and game members that are different for each model are arranged on the stage, the number of changes in the model change is reduced, and the design work can be simplified.

(Third modification of the central device 5)
The central device 305 of the third modification shown in FIGS. 23 to 25 is obtained by changing the stage structure of the central device 205 of the second modification, and the other configurations are the same. In addition, the pachinko machine of this form is changed from the first type of pachinko machine 1 to a third type of pachinko machine called a right object. Accordingly, illustrations and descriptions of common parts are omitted as appropriate, and portions to be described are illustrated and described below. In the drawing, elements corresponding to the above-described modification are described by adding 300 to the same product number, and new numbers are assigned to new elements. As shown in FIGS. 23 to 25, on the stage 344 of the central device 305 of this example, a large number of obstacle protrusions 340 are erected, and a third type starting port 307 and a distribution device 370 as game devices are arranged. ing. The third type starting port 307 includes an annular outer edge member 372 having a notch 371 through which a game ball can pass, and a rotating member 374 that has a recessed portion 373 that can receive the game ball and rotates within the outer edge member 372. A drive unit (not shown) for driving the rotating member 374 is disposed on the back side of the stage 344. As shown in FIG. 25, the stage 344 is provided with a ball outflow hole 375 through which a game ball passes. In addition, on the back side of the stage 344, a ball assembly cage (not shown) similar to that shown in the second modification is arranged and connected to the ball outflow hole 375. With such a configuration, when the recess 373 is in a position aligned with the notch 371, the game ball can pass through the notch 371 and flow into the recess 373, and the game ball received in the recess 373 is rotated by the rotation member 374. At the same time, when the recessed portion 373 reaches the ball outflow hole 375, it falls from the ball outflow hole 375 and flows out into the ball assembly cage.

  As shown in FIG. 25, the distribution device 370 is provided with an opening / closing plate 376. The open / close plate 376 can be changed between a closed position (shown in the figure) that is substantially parallel to the surface of the stage 344 and an open position that is substantially upright on the stage 344, and the open / close plate 376 is opened and closed on the back side of the stage 344. A drive mechanism (not shown) for driving is installed. For this reason, when the open / close plate 376 is in the closed position, the game ball does not flow into the sorting device 370, but when the open / close plate 376 is in the open position, the game ball easily flows in. In addition, the inside of the sorting apparatus 370 is divided into three, and the central part is a specific area 377 and the left and right are a normal area 378. A game ball that has flowed into the sorting apparatus 370 has a specific area 377 or a normal area 378. pass.

  In the pachinko machine provided with the central device 305, a game similar to that of the publicly known type 3 pachinko machine is performed. When the winning symbol is displayed, the opening / closing plate 376 of the sorting apparatus 370 is set to the open position for the set time. When the game ball that has flowed into the sorting device 370 during this release period passes through the specific area 377, the special game is started. In the special game, when a game ball enters the third type starting port 307 (more precisely, after passing through the ball outflow hole 375), the attacker is opened, and it becomes very easy to win. This attacker may replace the attacker 208 shown in FIG. 18 with an attacker for the third kind pachinko machine. For simplicity, the V region passing sensor of the attacker 308 (not shown because it corresponds to the attacker 8 in FIG. 1) is removed, and only 10 count sensors can be used. The attacker is closed when 30 seconds have elapsed after opening or when the number of winning balls for the attacker reaches ten. Then, when a game ball enters the third type starting port 307 again, the attacker is opened and closed in the same manner as described above. Each time the player enters the third type starting port 307, the attacker is repeatedly opened and closed, and the special game ends when the number of times the attacker has opened reaches the specified number (16 in the third modified embodiment).

  Similarly to the central device 205 of the second modified form, the central device 305 can also be attached to and detached from the stage 344, and a gaming device (the third type starting port 307, the sorting device 370) and a gaming member (the obstacle protrusion 340) are attached to the stage 344. Since it is arranged, the same effect as the second modified embodiment can be obtained. In addition, the stage of the center role described in the second modification and modification includes not only the above-described gaming device (start winning device, type 3 starting port, etc.) and gaming members (such as obstacle protrusions), but also other A gaming member such as a gaming device, a entrance, a lamp, a windmill, or the like may be provided.

  The distribution device here is a configuration in which, for example, a game ball entered into a tulip type entry device enters a so-called crune having a plurality of holes, and when the entered game ball enters a set hole You may comprise so that it may become a special game, and another structure may be sufficient. In addition, when employ | adopting a tulip type entrance device, if this is not open | released, it is preferable to comprise so that entrance is impossible. Also, game devices such as a variable display device, an attacker, a third type starting port, and a starting winning device are not limited to these configurations. For example, the method of attaching and detaching the stage is not limited to the above examples, and various implementations are possible. If the stage is made of wood, foam resin, etc., it becomes possible to drive game nails and adjust the nail (by changing the angle of the game nails by hitting the game nails etc., for example, changing the entrance rate to the entrance device etc. ) Is possible. In this case, the stage may be made of a material other than wooden or foamed resin as long as it does not interfere with the game nail.

(Fourth modification of the central device 5)
Next, a central device 405 which is a fourth modification in which a gaming device such as a winning device and gaming members such as obstacle protrusions are provided on the stage will be described with reference to FIGS. In addition, the pachinko machine of this form changes the stage structure of the central apparatus 5 of the above-mentioned embodiment. The present modification is to increase the preference by increasing the flow path length and the play time of the game ball in the central device to change the behavior of the game ball, and to effectively use the space of the central device. Accordingly, illustrations and descriptions of common parts are omitted as appropriate, and portions to be described are illustrated and described below. In the drawing, elements corresponding to those in the above-described embodiment are described by adding 400 to the same product number, and new elements are given new numbers.

  The central device 405 is a center game 406 that is discharged after the game ball B (see FIG. 27) is introduced and played, and a compound game kit (hereinafter referred to as a game kite) that plays the game ball B introduced into the center game 406. 469), a liquid crystal display board 405a having a 4-inch liquid crystal display screen visibly fixed to the center accessory 406, and a back plate 434c is provided around the liquid crystal display board 405a.

  As shown in FIG. 26, a floating cage 469 simulating a highway junction, separation zones 457a to 457d, architectural models 458a and 458b, and an exit gate 467 are fixed to a stage 444 that forms the bottom surface inside the frame 432, and It occupies approximately 1/3 to 2/3 rank of the accessory 406 in the vertical direction. That is, as shown in FIG. 27, the floating rod 469 having an open U-shaped cross section has a main passage 470 having a relatively large cross section and a first sub passage 471 having a relatively small cross section branched from the main passage 470. Or a seventh sub-passage 477. The main passage 470 is installed between the left and right ball outlets 453a and 453b, and is inclined gently and low from the left and right ends to the center. In addition, first to fourth passage outlets 481 to 484 and separation bands 457a to 457d (see FIG. 26) are formed in the central portion of the stage 444 in the left-right direction, and a tree model is disposed on them. . In addition, architectural models 458a and 458b simulating a two-story building are disposed on the left and right sides of the stage 444. An exit gate 467 is provided at the front portion of the third passage outlet 483, and the exit gate 467 is located almost immediately above the starting entrance 407. A portion of the stage 444 provided with the gate-shaped exit gate 467 is inclined low toward the front end side.

  As shown in FIG. 27, first to seventh auxiliary passages 471 to 477 are branched from the main passage 470. The first sub-passage 471 branches from the left end front portion of the main passage 470 and curves, extends forward of the stage 444 and reaches the first passage outlet 481. The second sub-passage 472 branches from the front end of the right end of the main passage 470, extends to the left side of the main passage 470 while curving, passes under the main passage 470 from the front to the back and from the back to the front, and exits from the second passage. 482 has been reached. The third sub-passage 473 is bent from the left end deep part of the main passage 470, passes under the main passage 470, extends forward of the stage 444, and reaches the third passage outlet 483. The fourth sub passage 474 branches from the right end deep part of the main passage 470 and curves, passes under the main passage 470, extends forward of the stage 444, and reaches the fourth passage outlet 484. The fifth sub-passage 475 branches off from the left middle inner part of the main passage 470, is bent and is connected to a part of the second sub-passage 472 so that the game balls B can join. The sixth and seventh auxiliary passages 476 and 477 are branched from the center front and the rear portion of the main passage 470, respectively, bent and connected to the intermediate portions of the second and fourth auxiliary passages 472 and 474, respectively. B is able to join. That is, the main passage 470 and the second to fifth sub-passages 472 to 475 intersect three-dimensionally, and gradually incline from the end connected to the main passage 470 toward the passage outlets 481 to 484. An inclination angle (so-called bank angle) in the width direction is appropriately set in each passage in consideration of the fact that the game ball B can flow smoothly and a centrifugal force is generated in the curved portion. The arrangement of the passage outlets 481 to 484 is set so that the game balls B that have flowed out have different easiness of passing through the outlet rogate 467. In the present modified embodiment, the third passage outlet 483 and the outlet gate 467 are arranged on substantially the same straight line, and the game ball B released from the third passage outlet 483 is easy to pass through the outlet gate 467. Since the exit gate 467 is located almost immediately above the starting entrance 407, the game ball B that has passed through the exit gate 467 easily enters the starting entrance 407. The low surface portion 478 of the main passage 470 is formed substantially horizontally, and the momentum of the game ball B is distributed so as to be evenly distributed without being biased to any of the sixth sub passage 476 and the seventh sub passage 477. Is weakened.

  As a modification, the structure, number, arrangement, etc. of the main passage 470 or the sub passages 471 to 477 can be appropriately set. They are U-shaped in cross section, but instead of this, a cylindrical shape may be used, and the cross-sectional shape can be arbitrarily set within a range in which the game ball B can pass. The idle rod 469 may be integrally formed or may be configured to connect parts. Further, if at least one of the sub passages 471 to 477 is a detachable attachment type, it is easy to change the course. The number of stages 444 is not limited. For example, a plurality of stages may be provided, or a stage having a function different from that of the stage 444 (for example, a function of collecting and distributing the game balls B) may be provided. As described above, various modifications can be made by those skilled in the art. The separation bands 457a to 457d or the exit gate 467 may be omitted, or may be replaced with another game member (for example, a tulip type variable winning device). Arrangement of game members such as obstacle nails, windmills, or blocks in the main passage 470 of the floating cage 469 in consideration of prevention of ball clogging and effective distribution of the game balls B to each sub-passage Is possible. Further, a movement or stop may be changed by providing a roller to change the moving speed or moving direction of the game ball B, or temporarily stopping at a position advantageous to the player. Furthermore, a sensor for detecting the passage of the game ball B may be attached at an appropriate place, and the screen of the liquid crystal display board 405a may be changed or the starting entrance 407 may be opened due to the detection of this sensor. In this modified embodiment, the main passage 470 and the sub passages 471 to 477 have a U-shaped cross section as shown in FIGS. 29 (a) and 29 (b), but a cylindrical passage 470a as shown in FIG. 29 (c). Or a U-shaped passage 470b as shown in FIG. Further, the material of the ridge may be any of transparent, translucent, and non-transparent. Furthermore, you may comprise by the metal mesh channel | path 470c as shown in the figure (e).

  Next, the behavior of the game ball in the central device 405 will be described. As shown in FIGS. 26 and 27, when the game ball B enters the ball inlet 450a or 450b, it passes through the warp bar 452a or 452b, flows out of the ball outlet 453a or 453b, and flows out to the main passage 470. When entering the first sub-passage 471 from the main passage 470, it flows out from the first passage outlet 481 to the stage 444. When entering the second sub-passage 472 from the main passage 470, it flows out from the second passage outlet 482 to the stage 444. When entering the third sub-passage 473 from the main passage 470, it flows out from the third passage outlet 483 to the stage 444, and generally passes through the exit gate 467. When entering the fourth sub-passage 474 from the main passage 470, it flows out from the fourth passage outlet 484 to the stage 444. When entering the fifth sub-passage 475 from the main passage 470, it passes through the second sub-passage 472 and flows out from the second passage outlet 482 to the stage 444. When entering the sixth sub-passage 476 from the main passage 470, it passes through the second sub-passage 472 and flows out from the second passage outlet 482 to the stage 444. When entering the seventh sub passage 477 from the main passage 470, it passes through the fourth sub passage 474 and flows out from the fourth passage outlet 484 to the stage 444.

  In this manner, the game ball B that has flowed into the game basket 469 can be caused to flow down in various ways. Therefore, the behavior of the game ball B in the central device 405 can be complicated, the flow path length and the play time can be increased, and the preference can be improved. Also, as described above, there is a possibility of a special game (described later) when winning at the starting entrance 407, so the player is very concerned about whether or not to win the starting entrance 407. Therefore, it will be anxious whether the game ball B falls from which position of the central device 405, especially whether it passes the 3rd channel | path exit 483 and the exit gate 467. Therefore, the interest of the game can be enhanced. A person skilled in the art can make various modifications to the shape, structure, and combination of the central device 405. For example, all of the game balls B that have entered the warp kites 452a and 452b are guided to the game kite 469. By doing so, the game ball B may be returned to the outside of the center accessory 406 or guided to the stage 444.

  A central device 405 ′ shown in FIG. 28 as a modification of the central device 405 will be described. This is because the exits of the first passage outlet 481 to the fourth passage outlet 484 are shortened, or a change is made such that the position of the floating rod 469 itself is retreated, so that there is a gap between them and the outlet gate 467. A space is formed, and a plurality of pins 490 project vertically from the space. Since the flow path of the game ball B discharged from the first passage outlet 481 to the fourth passage outlet 484 is changed by the pin 490, whether or not the game ball B passes through the output rogate 467 when released from the passage outlet. This makes it difficult to predict and improves preference. In addition, about the structure which is common in central apparatus 405 'and central apparatus 405, it shows in figure and description is abbreviate | omitted and quotes the same product number as the above-mentioned change form.

  According to this modification, the behavior of the game ball that has flowed into the central device can be complicated, the flow path length of the game ball and the play time can be increased, and the preference can be improved. It is possible to randomly move the game ball guiding unit by changing the course of the game ball flowing into the stage in various ways. Therefore, the behavior of the game ball in the game ball guiding unit, the subsequent drop position, and the like change variously, so that the preference is improved and the space is effectively used. In addition, since a plurality of passages are three-dimensionally crossed, it is possible to smoothly flow down the game balls along the long path while combining the behavior of the game balls in various directions. The preference is improved.

(Fifth modification of the central device 5)
Next, a central device 505, which is a fifth modification in which a gaming device such as a winning device and a gaming member such as an obstacle projection are provided on the stage, will be described with reference to FIGS. In addition, the pachinko machine of this form changes the stage structure of the central apparatus 5 of the change form mentioned above. The present modification is to provide a course changing means composed of a movable member in the central device, to change the behavior of the game ball to enhance the preference, and to effectively use the space of the central device. Accordingly, illustrations and descriptions of common parts are omitted as appropriate, and portions to be described are illustrated and described below. In the drawing, the elements corresponding to the above-described modification are described by adding 500 to the same product number, and a new number is assigned to a new element.

  As shown in FIG. 30, an upper stage 544 and a lower stage 546 are provided stepwise inside the frame body 532. Note that the upper stage 544 and the lower stage 546 are inclined, and the back side is slightly higher than the near side. In addition, a vertical plate 544a is connected to the front side of the upper stage 544, and a ball guide path 544b projects from the center thereof. Further, a course changing member 523 is disposed so as to protrude on the upper stage 544. A recess 546b is formed between the pair of inclined plates 546a at the center of the lower stage 546. The upper stage 544 is provided with a movement hole 524, and the course changing member 523 is supported by an upper movement protrusion 525 or a lower movement protrusion 526 that penetrates the movement hole 524. As shown in FIG. 32, the upper movement protrusion 525 is erected on the upper slide plate 527. The upper slide plate 527 is provided with a moving protrusion protruding hole 528, and the lower moving protrusion 526 passes through the moving protrusion protruding hole 528. Also, rack teeth 529 are provided on the lower surface of the upper slide plate 527 (see FIGS. 34 and 35), and the rack teeth 529 mesh with a gear 548 fixed to the output shaft 547 of the stepping motor 545. . The stepping motor 545 is fixed to the back plate 534c via the mounting plate 549. The upper slide plate 527 is inserted into a slide groove 557 provided on the back surface of the vertical plate 544a connected to the front side of the upper stage 544 and a slide groove 558 provided on the front surface side of the back plate 534c. The slide grooves 557 and 558 (see FIG. 32) are slidable.

  The lower movement protrusion 526 is erected on the lower slide plate 567. Rack teeth 568 are provided on the upper surface of the lower slide plate 567 (see FIG. 33), and the rack teeth 568 also mesh with the gear 548 as shown in FIG. As shown in FIGS. 31 and 32, the lower slide plate 567 (see FIG. 33) is inserted into a slide groove 569 provided on the back surface of the vertical plate 544a and a slide groove 570 provided on the back plate 534c. The slide grooves 569 and 570 can slide freely.

  With such a configuration, when the stepping motor 545 is operated, the upper slide plate 527 and the lower slide plate 567 can be moved in opposite directions. Note that the stepping motor 545 is controlled by a control circuit (not shown) and repeats normal rotation and reverse rotation for each set number of steps. Accordingly, the upper slide plate 527 and the lower slide slope 567 move reciprocally.

  The operation of the central device 505 will be described. During the operation of the pachinko machine, the stepping motor 545 operates (forward and reverse), and the upper slide plate 527 and the lower slide plate 567 repeat reciprocating movement (see FIGS. 36A and 36B). Accordingly, the course changing member 523 supported by the upper moving projection 525 standing on the upper slide plate 527 or the lower moving projection 526 standing on the lower slide plate 567 also repeats reciprocating movement on the upper stage 544. .

  As shown in FIGS. 30 and 31, if there is a game ball that has entered the ball inlets 550a and 550b, the game balls are moved by the warp rods 552a and 552b and released onto the upper stage 544 from the ball outlets 553a and 553b. The Since the upper stage 544 is slightly inclined toward the front side, the game ball that has reached the upper stage 544 rolls toward the lower stage 546. However, since the course changing member 523 repeats reciprocating movement so as to cross the rolling path, most of the game balls rolling on the upper stage 544 come into contact with or collide with the course changing member 523. Can be changed. Many of these game balls fall from the upper stage 544 to the lower stage 546, move on the lower stage 546 and fall from the recess 546b, or fall before reaching the recess 546b. Since the starting entrance 507 is installed directly below the center accessory 506, the game ball that has dropped from the recess 546b wins the start entrance 507 rather than the game ball that has dropped before reaching the recess 546b. It is highly possible. A part of the game ball rolling on the upper stage 544 flows into the ball guiding path 544b and falls from the tip thereof, but the ball guiding path 544b is located immediately above the starting entrance 507. Therefore, it can be said that the game ball dropped from here has a higher possibility of winning the starting entrance 507 than the game ball dropped from the recess 546b of the lower stage 546.

  In this way, the course of the game ball that has flowed onto the upper stage 544 can be changed in various ways, and can be randomly moved on the upper stage 544. Therefore, the behavior of the game ball on the upper stage 544, the subsequent drop position, and the like change variously, so that the preference is improved and the space is effectively used. In addition, as described above, there is a possibility of a special game when winning the starting entrance 507 (not shown because it corresponds to the starting entrance 7 in FIG. 1). I am very concerned about whether or not to win a prize. Therefore, it will be anxious depending on which position of the center accessory 506 the game ball falls from, particularly whether or not it falls from the ball guide path 544b. Therefore, the interest of the game can be enhanced.

  In this modification, the course changing member is reciprocated left and right, but it may be moved up and down, back and forth, obliquely and rotationally, or a combination thereof. Also, the movement speed of the route changing member may be changed, or the movement or stop may be changed, for example, temporarily stopped at a position advantageous to the player. The structure, number, position, etc. of the slide plate, the course changing member, the motor, the gears, etc. can be variously changed. Next, an example in which the number of slide plates is three will be described as an example of such a change.

(Modification)
The modification shown in FIG. 38 is obtained by slightly changing the drive mechanism. Parts corresponding to the fifth modification form are given dashes, and new numbers are assigned to the additional elements. In this example, the upper slide plate 527 ′, the middle slide plate 571, and the lower slide plate 567 ′ are used. Similar to the fifth modification, the upper slide plate 527 ′ includes rack teeth 529 ′ on the lower surface, and the lower slide plate 567 ′ includes rack teeth 568 ′ on the upper surface. On the other hand, the middle slide plate 571 is provided with rack teeth 572 and 573 on both upper and lower surfaces. The rack teeth 529 ′ of the upper slide plate 527 ′ and the rack teeth 572 of the middle slide plate 571 mesh with the gear 548 ′ fixed to the output shaft 547 ′ of the stepping motor 545 ′, and the rack of the middle slide plate 571 is engaged. The teeth 573 and the rack teeth 568 ′ of the lower slide plate 567 ′ are in mesh with a driven gear 575 that is rotatably supported by a shaft pin 574 that is fixed to the main body side of a center accessory (not shown). Although not shown in the drawings, the moving projections erected on the lower slide plate 567 ′ extend through both the movement projection projection holes of the middle slide plate 571 and the movement projection projection holes of the upper slide plate 527 ′. The movement protrusions erected on the middle slide plate 571 extend through the movement protrusion protrusion holes of the upper slide plate 527 ′.

  With the configuration as described above, the course changing member can be moved by each of the upper slide plate 527 ′, the middle slide plate 571, and the lower slide plate 567 ′. It is possible to randomly move on the stage by changing the course of the game ball flowing into the stage in various ways. Accordingly, the behavior of the game ball on the stage, the subsequent drop position, and the like change variously, so that the preference is improved and the space is effectively used.

  Examples of the course changing member include obstacle protrusions and obstacle nails arranged on the stage, but the above-described effects can be improved by making them movable. Therefore, in the ball game machine, a moving member that moves on the stage and a drive mechanism that drives the moving member are provided as the course changing means. The moving member moves on the stage by, for example, circling or reciprocating along a fixed trajectory. The movement of the moving member may be regular or irregular, but even if it is regular, for example, the timing at which the game ball flows into the stage itself cannot be predicted, so the interference state between the game ball and the moving member is random. It becomes.

(Sixth modification of the central device 5)
Next, a central device 605 that is a sixth modification in which a gaming member is provided on the stage will be described with reference to FIGS. In addition, the pachinko machine of this form is provided with a transport member in addition to the route change member of the central device 505 of the fifth modified form, and changes the behavior of the game ball to improve the preference and effectively use the space of the central device. Is to plan. Accordingly, illustrations and descriptions of common parts are omitted as appropriate, and portions to be described are illustrated and described below. In the drawing, the elements corresponding to the above-described modification are described by adding 600 to the same product number, and a new number is assigned to a new element.

  As shown in FIG. 39, the upper stage 644 of the center accessory 606 is provided with an oval moving hole 624. Note that the upper stage 644 and the lower stage 646 are inclined in the same manner as in the fifth modification. Further, the upper stage 644 is provided with a ball separating member 668 standing between the moving hole 624 slightly on the right side of the center and the ball guiding path 644b. Six moving protrusions 625 are inserted into the moving hole 624, and six course changing members 623 supported by the moving protrusion 625 are arranged on the upper stage 644. Although details will be described later, the course changing member 623 circulates on the upper stage 644 along the movement hole 624. The shortest distance between the course changing member 623 and the ball separating member 668 during the circulation is less than the radius of the game ball.

  As shown in FIGS. 40A and 40B, the course changing member 623 includes a front plate 626 and a back plate 627, and the back plate 627 is provided with an insertion hole 628 for inserting the moving projection 625. . Three of the six course changing members 623 have a magnet 629 enclosed in a front plate 626, and a game ball can be attracted by the magnet 629.

  A drive mechanism 670 is incorporated below the upper stage 644 as shown in FIGS. 41 and 42. The drive mechanism 670 includes a mechanism attachment plate 657 for supporting each part. A stepping motor 645 is attached to the motor attachment plate 679 fixed to the mechanism attachment plate 657, and a drive pulley 648 is attached to the stepping motor 645. Specifically, as shown in FIG. 42, the output shaft 647 and the drive pulley 648 are connected by fitting the shaft fixing hole 649 of the drive pulley 648 to the output shaft 647 of the stepping motor 645.

  As shown in FIG. 42, a shaft pin 674 having a flange-shaped support portion 658 is erected on the mounting portion 659 fixed to the mechanism mounting plate 657. The shaft pin 674 passes through the shaft mounting hole 672 of the driven pulley 671, and the driven pulley 671 is rotatable about the shaft pin 674. A stop member 673 fitted to the tip of the shaft pin 674 prevents the driven pulley 671 from falling off. On the side surfaces of the driving pulley 648 and the driven pulley 671, a gear-like convex portion 675 is provided. In addition, the driving pulley 648 and the driven pulley 671 are provided with a flange-like belt support portion 676 at the lower side surface. A belt 678 (see FIG. 43) having a concave portion 677 corresponding to the convex portion 675 is wound around the driving pulley 648 and the driven pulley 671, and the convex portion 675 and the concave portion 677 are engaged with each other. In addition, the above-described moving projections 625 are erected on the upper edge portion of the belt 678 at substantially equal intervals.

  In the pachinko machine of the sixth modified form, the stepping motor 645 is operated throughout its operation, and the belt 678 is rotated counterclockwise. Therefore, the course changing member 623 supported by the moving protrusion 625 circulates counterclockwise along the moving hole 624 on the upper stage 644. As shown in FIG. 39, if there is a game ball that has entered the ball inlets 650a and 650b, the game ball is moved by the warp rods 652a and 652b and discharged from the ball outlets 653a and 653b onto the upper stage 644. Since the upper stage 644 is slightly inclined toward the front side, the game ball reaching the upper stage 644 rolls toward the lower stage 646. However, as shown in FIG. 44, since the course changing member 623 circulates so as to cross the rolling path, most of the game balls rolling on the upper stage 644 are in contact with the course changing member 623 or collide. At this time, some game balls that have contacted or collided with the course changing member 623 containing the magnet 629 may be attracted by the magnet. In addition, most of the game balls that have contacted or collided with the course changing member 623 that does not incorporate the magnet 629 (see FIGS. 40A and 40B), or that have not been attracted to the magnet 629, from the upper stage 644 to the lower stage 646. And fall on the lower stage 646 to fall from the recess 646b or before reaching the recess 646b. Since the starting ball entrance 607 is installed directly below the center accessory 606, the game ball dropped from the recess 646b wins the start entrance port 607 more than the game ball dropped before reaching the recess 646b. It is highly possible.

  On the other hand, the game ball attracted by the magnet 629 is transported as the course changing member 623 circulates, but when it reaches the vicinity of the ball separation member 668, the ball separation member 668 (see FIG. 44) contacts the game ball. The game ball is released from being attracted by the magnet 629. Most of the released game balls flow into the ball guide path 644b and fall from the tip thereof. Also, some game balls that have rolled on the upper stage 644 without being attracted by the magnet 629 flow into the ball guide path 644b and fall from the tip thereof. Since the ball guide path 644b is located immediately above the starting entrance 607 (not shown because it corresponds to the starting entrance 7 in FIG. 1), the game ball dropped from here is a recess 646b of the lower stage 646. It can be said that there is a higher possibility of winning the starting entrance 607 than the game ball that has fallen.

  In this way, the path of the game ball that has flowed onto the upper stage 644 is changed in various ways to randomly move on the upper stage 644, or is attracted by the magnet 629, transported, and released near the entrance of the ball guide path 644b. You can also Therefore, the behavior of the game ball on the upper stage 644, the subsequent drop position, and the like change variously, so that the preference is improved and the space is effectively used. In addition, as described above, there is a possibility of a special game when winning at the starting entrance 607, so the player is very concerned about whether or not to win the starting entrance 607. Therefore, it will be anxious whether the game ball is dropped from which position of the center accessory 606, particularly whether it is attracted and transported by the magnet 629 and dropped from the ball guide path 644b. Therefore, the interest of the game can be enhanced.

  In this modified form, the course changing member is moved around, but it may be moved up and down, front and rear, obliquely and rotationally, or a combination thereof. In addition, the movement speed and the moving direction of the course changing member may be changed, or the movement and stop may be changed, for example, temporarily stopped at a position advantageous to the player. Although it is configured to be attracted and transported by a magnet, it may be transported by other means. Further, the number of conveying members (the course changing member 623 including the magnet 629 in the case of the sixth modified embodiment) is not particularly limited as long as it is one or more. The structure, number, position, and the like of the moving hole, the course changing member, the motor, the belt, and the like can be variously changed. For example, a plurality of moving holes may be provided and the course changing member may be moved correspondingly. Further, for example, if the route changing member is a detachable attachment type, it can be easily changed to a route changing member having a different shape and design depending on the model of the gaming machine. Furthermore, the number of stages is not limited. For example, the lower stage shown in the fifth and sixth modifications may not be provided, or a stage having a function different from those of the upper and lower stages may be provided. The power source is not limited to a motor such as a stepping motor, but may be a solenoid or a linear motor.

(Seventh modification of the central device 5)
The central device 705, which is the seventh modification shown in FIGS. 45 to 49, incorporates the structure of a baseball board in place of the course changing member and the transport member of the central device 605 of the sixth modification, and also devise the software. In addition, as shown in FIG. 45, the size and arrangement of the central device 705 in the game board 702 are slightly changed. Accordingly, illustrations and descriptions of common parts are omitted as appropriate, and portions to be described are illustrated and described below. In the drawing, the elements corresponding to the above-described modified form are described by adding 700 to the same product number, and a new number is assigned to a new element.

  45 to 47, the frame 732 of the central device 705 includes a liquid crystal display panel 705a, two large and small LED display panels 705b and 705c having an LED dot matrix, and S, B, and O drawn on the back plate 734c. A plurality of LEDs 705d arranged corresponding to the characters are attached. Inside the frame body 732, a lower stage 744, an upper stage 746, and a vertical plate 744a forming a step are provided, and a ball outlet 744b is opened in the vertical plate 744a. The lower stage 744 has a recess 746b at the center, and the recess 746b is provided with a slight inclination from the back side toward the front side. Inclined portions 746a that incline toward the recessed portion 746b are provided on the left and right sides of the recessed portion 746b. End portions 746c connected to the inclined portions 746a are also slightly inclined toward the inclined portions 746a. Therefore, if there is a game ball on the lower stage 744, the game ball is guided toward the recess 746b by these inclinations, and falls from the recess 746b to the near side.

  The upper stage 746 is provided with a slight inclination from the back side toward the front side, and a figure simulating a baseball field diamond is drawn on the upper stage 746 (see FIGS. 46 and 47). On the upper stage 746, one batter doll 723 and two defensive dolls 725 are arranged. As shown in FIG. 48, the batter 723 has a structure that reciprocally rotates around a rotation shaft 747 within a set range, and the bat portion 726 is swung back and forth according to the rotation. In the seventh modification, a stepping motor (not shown) is used as a drive source for the batter 723, but other types of motors, rotary solenoids, and the like can be used as the drive source. The defensive doll 725 is attached to a support column 727 that reciprocates in a moving hole 724 provided in the upper stage 746, and reciprocates on the upper stage 746 within a range regulated by the moving hole 724. In the seventh modified embodiment, as a mechanism for reciprocatingly driving the defensive doll 725, a motor and a rack and pinion mechanism (both not shown) that periodically rotate forward and backward are employed, but this is different. It does not matter as a structure.

  As shown in FIG. 47, the upper stage 746 is surrounded by a fence 728, and a hit zone 729, an out zone 759, and a ball outlet 758 are provided. The hit zone 729 and the out zone 746 are used as receiving holes for a part of the game balls from the upper stage 746, and the game balls that have flowed into the hit zone 729 correspond to the hit zones 729 below the floor of the upper stage 746. The game ball that has been detected by the hit sensor 770 (see FIG. 47 and FIG. 49) installed on the ball and then flows out from the ball outlet 744b onto the lower stage 744 and flows into the out zone 759 is detected by the sensor or the like. Without flowing out from the ball outlet 744b onto the lower stage 744. Further, the upper edge of the hit zone 729 is an advertisement area 772, and as illustrated in FIG. 47, a company name, a product name, etc. are drawn corresponding to each hit zone 729. Further, a large number of audience dolls 767 are arranged between the fence 728 and the frame body 732. That is, the upper stage 746 and its surroundings have a structure simulating a baseball field.

  As shown in FIG. 47, four advertisement hold lamps 774 of LEDs are arranged on the upper edge of the central portion of the fence 728. The partition portion 763 is provided with a pair of ball inlets 750 a and 750 b, and warp rods 752 a and 752 b arranged along the outer surface of the frame body 732 are connected to the ball inlets 750 a and 750 b. The other ends of the warp rods 752a and 752b are connected to a ball outlet 758 via a path (not shown), and the game balls that have entered the ball inlets 750a and 750b are discharged from the ball outlet 758 onto the upper stage 746.

  As shown in FIG. 47, the game ball released from the ball exit 758 onto the upper stage 746 rolls to the near side of the upper stage 746, that is, to the batter 723 side, and if the timing is good, the bat 726 of the batter doll 723 Be blown. Some of the hit game balls flow into the hit zone 729, but for example, some of them are bounced back by the defensive doll 725 and fall from the upper stage 746 to the lower stage 744, and others flow into the out zone 759. As a result, the player can feel as if he is a batter or watching baseball. Further, start passage openings 754a and 754b are opened on the side surfaces of the left decoration portion 731a and the right decoration portion 731c (the start passage openings 754a of the left decoration portion 731a are not shown), and the start passage openings 754a and 754b The inflowing game ball has a structure that falls downward from an outlet (not shown) provided at the lower ends of the left decorative portion 731a and the right decorative portion 731c.

(A form in which software control of advertisement display is performed in the seventh modified form)
The advertisement image data is stored in the advertisement ROM 868, which is different from the pachinko machine of FIG. 1 (see FIG. 15) in that the advertisement ROM 868 can be attached to and detached from the main control board 841 and the ROM can be updated. . Further, as shown in FIG. 49, a hit sensor 770 is additionally connected to the terminal board 853. The main control board 841 can acquire a hit signal from the hit sensor 770, a start signal from the winning ball detection switch 822, and a winning signal from other winning holes, and is installed on the game board 702 including opening / closing of the opening / closing plate 708a. It is possible to control the operation of the winning device or the like. Further, the display on the liquid crystal display panel 705a, the LED display panels 705b and 705c, and the LED 705d can be controlled. In the following description, step is abbreviated as S. The determination routine shown in FIG. 50 is a well-known one, and it is determined whether or not a start ball has been entered (S201), a determination is made (S202), and a display is instructed to the liquid crystal display panel 705a in accordance with the determination (S203). It is determined whether or not it is a win (S204), and if it is a win, a special game is performed (S205).

  As shown in FIG. 51, when a predetermined advertisement condition is satisfied, if a hit signal from the hit sensor 770 is input to the main control board 841 (S301: YES), the hit sensor 770 that has sent the hit signal. (Position of hit zone 729) is stored in the set area of RAM 862 to store that there was a hit signal, and one advertisement hold lamp 774 is lit (S302). In this embodiment, a maximum of four memories with the hit signal are stored. If there are already four memories, the fifth and later are not stored. When there is no hit signal (S301: NO) or following the processing of S302, the main control board 841 determines whether or not the position of the hit sensor 770 is stored in the RAM 862 (S303). If there is (S303: YES), the oldest one of the memories is read, the advertisement image data associated with the position of the hit sensor 770 is read from the advertisement ROM 868, and transferred to the special symbol control board 870, Display is instructed (S304). The advertisement image data selected here corresponds to the advertisement drawn on the hit zone 729 (for example, the advertisement of ΔΔ bank is drawn on the hit zone 729 corresponding to the position of the hit sensor 770). (Sometimes, Δ △ bank advertisement image data is selected).

  Then, the storage of the position of the oldest hit sensor 770 is deleted from the RAM 862, one advertisement hold lamp 774 is turned off (S305), and this process is terminated. In addition, when the position of the hit sensor 770 is not stored (S303: NO), the main control board 841 ends the advertisement process as it is.

  The special symbol control board 870 that has received the advertisement image data displays the advertisement image on the liquid crystal display panel 705a as follows, as shown in FIG. One advertisement is set to end in about 10 seconds, and the display of one advertisement image is ended when the set time elapses. As shown in FIG. 52, the special symbol control board 870 determines whether or not the symbols are being displayed on the liquid crystal display panel 705a (S401). Judgment is made (S402). If it is not during the special game (S402: NO), the special symbol control board 870 displays the advertisement image on the liquid crystal display board 705a in the first mode (only the advertisement image) shown in FIG. 53 (a) (S403). . If the special game is being played (S402: YES), the special symbol control board 870 displays the advertisement image on the entire screen of the liquid crystal display panel 705a as shown in FIG. The advertisement image is displayed on the liquid crystal display panel 705a (S404).

  If the variable display is in progress (S401: YES), it is determined whether or not the special symbol control board 870 is a reach (S405). If the reach is not reached (S405: NO), the special symbol control board 870 displays the advertisement image on the entire screen of the liquid crystal display panel 705a as shown in FIG. The advertisement image is displayed on the liquid crystal display board 705a in the second mode in which (the left symbol 7 in the figure is stationary and the middle and right symbols are changing) is displayed (S406).

  On the other hand, if it is reach (S405: YES), the special symbol control board 870 displays an advertisement image in the upper right corner of the liquid crystal display panel 705a as shown in FIG. 54 (a), and the central part of the liquid crystal display panel 705a. In a third mode (see FIG. 54 (a)) for displaying a success / failure display symbol (in FIG. 54, the left and right symbols 7 are stationary and the middle symbol is changing), the liquid crystal display panel 705a An advertisement image is displayed (S407). Subsequently, the special symbol control board 870 continues the third mode until the symbol display is confirmed (S408: NO) (S407), and if the symbol display is confirmed (S408: YES), the result is determined (S408: YES). S409).

  If it is a hit here (S409: YES), an advertisement image is displayed on the liquid crystal display panel 705a in the fourth mode (S404). If it is off (S409: NO), the second mode (see FIG. 53 (b)). The advertisement image is displayed on the liquid crystal display panel 705a (S410). After the processing of S403, S404, S406, or S410, the special symbol control board 870 ends the display of the advertisement image after the elapse of the set time described above, and ends this processing. When the advertisement image is not displayed, only the success / failure determination symbol is displayed as shown in FIG.

  The display mode of these advertisement images is an example, and other modes may be used. For example, as shown in FIGS. 56 (a) and 56 (b), the advertisement image is scrolled upward from the lower side of the screen, or the advertisement image is lowered along the right side of the screen as shown in FIG. 57 (a). It is also possible to scroll from the top to the top, or to scroll the advertisement image from the right side to the top side of the screen as shown in FIG. In addition, as shown in FIG. 58, it is possible to superimpose and display the success / failure display pattern with the advertisement image as a background. At this time, for example, processing of making the advertisement image easy to see by reducing or thinning the success / failure display symbol may be performed (in the example of FIG. 58, both reduction processing and thinning processing are performed).

  As described above, when entering the hit zone 729, the advertisement image selected according to the position (the advertisement image corresponding to the advertisement drawn on the hit zone 729) is displayed. The advertisement image can be displayed, and the execution of the advertisement display can be prevented from becoming monotonous, thereby improving the interest. In addition, there are a plurality of display modes, which are appropriately selected and changed according to the situation of the pachinko game, so that the advertisement display can be changed and the interest can be improved. In particular, in this embodiment, since the correspondence between the hit zone 729 and the advertisement is determined in advance, the player is expected to enter the hit zone 729 corresponding to the player's desired advertisement. be able to. Further, not only the starting entrance 707 but also the entrance into the hit zone 729 for displaying an advertisement can be noted, and the interest can be further enhanced. In an actual baseball stadium, a large display for reproducing play and displaying advertisements is often installed. In this embodiment, the baseball stadium is imitated on the upper stage 746 of the center actor 706. Since an advertisement is displayed on the liquid crystal display board 705a, a realistic feeling similar to an actual baseball field can be given.

  Further, in this modified embodiment, a prize ball is not paid out when a ball enters the hit zone 729, but a prize ball may be paid out based on the ball entered into the hit zone 729. Further, the determination of whether or not to display the advertisement may be made based on the occurrence of the jackpot. In this case, it can be considered that the presence or absence of advertisement display is related to the jackpot symbol. Specifically, advertisements are displayed only when jackpots occur on special symbols such as probability variation symbols and lucky number symbols, or ads are displayed only when jackpots occur on normal symbols other than these. Can be considered.

  Examples of the advertisement image display means include a display device including a liquid crystal display board, a CRT, a dot matrix, and the like. Advertisement images can be various such as character images, moving images, still images, and combinations thereof. Examples of the contents include commercial advertisements for companies, products, services, etc., public notices such as public relations of public offices, news distributed from mass media, and the like.

  The advertisement variation condition may be an event that occurs due to the execution of the ball game. For example, the entrance entrance and passage entrance (also referred to as a passing gate) are set as the advertisement fluctuation area, and the advertisement fluctuation condition may be satisfied when a game ball passing there is detected by a sensor or a switch. . Also, the advertising variation condition may be established when a known reach is reached or a big hit occurs, or the number of game balls shot into the game board surface becomes a set number (for example, 1,000 shots). The advertisement variation condition may be satisfied every time. Of course, other than these may be used. For example, in order to display an advertisement image of a product or the like that the player likes or wants to know, the player may fire a game ball aiming at a specific winning opening set in the advertisement fluctuation area, etc. It will also improve the interest of the ball game.

  Changes in the advertisement image include a change in the advertisement content (for example, switching from an advertisement for the X company to an advertisement for the Y company), a change in the display mode without changing the advertisement content (for example, while maintaining the X company, a part of the image is changed) Examples include modification by enlargement, reduction, etc., changing the advertisement image from a moving image to a still image, changing the scroll direction from vertical to horizontal, etc., and changing the display position and display size on the screen. It should be noted that there are a plurality of entrances and passages set as advertisement fluctuation areas, and when entering the entrance of A, the advertisement image of company X is displayed, and when entering the entrance of B, Y A configuration in which an advertisement image of a company is displayed is also possible.

  The image data of the advertisement image may be stored in various storage media in addition to the ROM, which may be read out sequentially and used, for example, sent from the hall computer of the amusement store to each ball game machine, It may be transmitted from a facility (host, server, etc.) outside the game store to the hall computer via a wired or wireless telephone line or the like and supplied to each ball game machine. When a storage medium such as a ROM is used, it can be updated so that, for example, a new product can be released or an advertisement image can be displayed according to the season or fashion. As the storage medium, various other general media such as a CD-ROM and a magneto-optical disk (MO disk, DVD) can be used.

  In addition, a determination means for determining whether or not to win when a predetermined determination execution condition is satisfied, a determination display means for displaying this determination, and a special game advantageous to the player due to the determination being successful. Some have special game execution means to execute. As the determination display means, a display device having a liquid crystal display panel, CRT, dot matrix or the like is often used, and as described above, these can also be used as advertisement image display means.

  A determination means for determining a hit / miss when a predetermined determination execution condition is satisfied, and a special game execution means for executing a special game advantageous to the player due to the determination being successful, The image control means instructs the advertisement image display means to display the determination result, and the advertisement image display means displays the instructed determination result. With this configuration, the ball game machine having the display device as described above is slightly improved (for example, a ROM for storing image data is added and software for controlling the display device is installed). The present invention can be implemented to the extent that it changes. Therefore, it is not necessary to use special devices and parts, and new burdens in development, design, manufacturing, and the like can be reduced. Furthermore, when the advertising fee is acquired from the advertiser by displaying the advertising image, it is possible to reduce the selling price of the ball game machine as much as it is.

(Mode of updating advertisement contents in the central device of the seventh modified mode)
In the above modification, the advertisement content is updated by updating the advertisement ROM 868. However, as shown in FIG. 59, a communication line can be used for updating the advertisement content, and an example will be described. An advertisement management device connected to a public communication line such as a telephone line is installed in the game hall, and this advertisement management device receives advertisement data periodically, for example, and distributes it to each ball game machine in the game. is there. In this example, the advertisement management device temporarily stores the received advertisement data, and distributes and stores the advertisement data to each ball game machine after the line connection is terminated. Each ball game machine displays an advertisement image using the advertisement data. Such an advertisement management apparatus can be realized by using a personal computer, for example, or may be shared by a hall computer. The Internet can also be used for receiving advertisement data. The distribution of the advertisement data may be performed directly by the advertiser or may be performed, for example, via a gaming machine manufacturer.

  As described above, an advertisement displaying an advertisement image on a pachinko machine 701 (see FIG. 45) that gives a player a game value due to a winning or the like being established by the behavior of a game ball shot on the game board surface. Image display means and image control for instructing the advertisement image display means to change or switch between display and non-display of the advertisement image due to establishment of a preset advertisement fluctuation condition by execution of the ball game Therefore, the advertisement image can be displayed in relation to the ball game, thereby improving the interest. In the above modification, the main control board 841 functions as image control means and determination means, and also functions as special game execution means in cooperation with the attacker 708. Further, the advertisement ROM 868 of the main control board 841 corresponds to the image storage means. The special symbol control board 870 and the liquid crystal display panel 705a cooperate to function as advertisement image display means.

(First modification of software for a pachinko machine equipped with a central device of a seventh modification)
In this modification, the software is changed as shown in FIGS. 62 and 63, and the game board configuration is changed as shown in FIGS. 60 and 61. Accordingly, illustrations and descriptions of common parts are omitted as appropriate, and portions to be described are illustrated and described below. In the drawing, elements corresponding to the above-described modified form are described by adding a dash to the same product number, and a new number is assigned to a new element. Here, as shown in FIG. 60, in addition to the starting entrance 707 ′, which is a well-known tulip-type variable winning device, it is also opened and closed by well-known tulip-type variable winning devices 709a, 709b, 709c, and an opening / closing plate 708a ′. And an attacker 708 ′ having two winning entrances 710 ′ and 712 ′. As shown in FIG. 61, the upper stage 746 ′ is surrounded by a fence 728 ′, and a single hit zone 729 corresponding to a receiving entrance, a double strike zone 748, a home run zone 759 and a ball exit 758 ′ are provided. The single hit zone 729, the two-stroke zone 748, and the home run zone 759 serve as receiving holes for a part of game balls from the upper stage 746 ′, and the game balls that flow into these zones enter the zones 729, 748, and 759, respectively. Correspondingly, it is detected by zone sensors 770a, 770b, 770c (shown in parentheses in FIG. 61) installed under the floor of the upper stage 746 ′, and then flows out to the back side of the game board 702 ′.

  As shown in FIG. 61, the game ball released from the ball exit 758 ′ onto the upper stage 746 ′ rolls to the near side of the upper stage 746 ′, that is, the batter doll 723 ′, and some of the game balls to the defensive doll 725 ′. The course is changed by contact. If the timing is good, the batter 723 'of the batter 723' is hit. Some of the hit game balls flow into the single hit zone 729, the double hit zone 748 or the home run zone 759, but for example, they are bounced back by the defensive doll 725 'and fall from the upper stage 746' to the lower stage 744 '. . In this way, with the configuration imitating the game, you can feel as if you are a batter or watching baseball. In the first modification, the circuit configuration shown in FIG. 49 is slightly changed. Although the circuit configuration is not shown, the difference is that the main control board 841 ′ (not shown because it corresponds to the main control board 841 shown in FIG. 49) has variable winning devices 709a, 709b, 709c (see FIG. 60). Are connected to zone sensor 770a to 770c (shown in parentheses in FIG. 61), a starting entrance 707 ′ (see FIG. 60), variable winning devices 709a, 709b, It is possible to control the opening and closing of the 709c and the attacker 708 ′.

  A game control main process that is repeatedly executed by the main control board 841 ′ during operation of the pachinko machine 701 ′ will be described with reference to FIGS. 62 and 63. As shown in FIG. 62, the main control board 841 'first executes a privilege granting subroutine (S500). The main control board 841 ′ determines whether or not the start winning signal is input from the starting entrance 707 ′ (S520). If the start winning signal is input (S520: YES), the reserved memory is 4 It is determined whether or not there are (hold full) (S530). If the number of reserved storages is three or less (S530: NO), the main control board 841 'makes a hit / fail determination (S540). Here, the determination is performed based on whether or not the count value of the determination random number generation counter matches a winning value (for example, 7).

  Next, the main control board 841 'determines whether or not the result of the hit can be displayed on the liquid crystal display panel 705a' (S550). In this modification, it is determined that display is not possible (S550: NO) when a special game, which will be described later, is being executed or when the liquid crystal display board 705a 'is displaying a symbol indicating that the game is not successful. If display is possible (S550: YES), the main control board 841 ′ will display a special symbol indicating a win if the determination is successful (for example, a symbol with three digits aligned, such as 777), and if it is off, the main control board 841 ′ In such a manner, a symbol that does not have three digits is instructed to the liquid crystal display panel 705a '(S560). A three-digit symbol is displayed in a variable manner on the liquid crystal display panel 705a '. For example, the three-digit symbol indicated by the main control board 841' is displayed by stopping in the order of left, right, and center.

  If display is not possible (S550: NO), the main control board 841 'turns on one additional hold lamp (S570) and stores the determination result in S540 as hold storage (S580). On the other hand, if the start winning signal is not input (S520: NO), the main control board 841 'determines whether or not there is a pending storage (S590). If there is an on-hold storage (S590: YES), it is determined whether or not display is possible (S600) as in the above-described S550, and if display is possible (S600: YES), as in S560, a winning special symbol or special off-line is obtained. The design is instructed to the liquid crystal display panel 705a '(S610), and the reserved storage instructed to be displayed here is deleted (S620).

  In addition, after the processing of S560, S580 or S620, or when there are four hold memories (S530: YES), when there is no hold memory (S590: NO), when display is impossible (S600: NO) Then, the process proceeds to S630, for example, various processes necessary for a special game and other pachinko games are performed, and then the game control main process is temporarily ended.

  As shown in FIG. 63, in the privilege granting subroutine described above, the main control board 841 ′ determines whether or not the game ball detection signal from the zone sensor 770c is input, that is, whether or not there is a game ball that has passed through the home run zone 759. Is determined (S501). If there is a game ball that has passed through the home run zone 759 (S501: YES), the main control board 841 'opens (widens) the three variable winning devices 709a, 709b, 709c in synchronization (S502). If there is no game ball that has passed through the home run zone 759 (S501: NO), the main control board 841 ′ determines whether or not a game ball detection signal from the zone sensor 770b is input, that is, a game that has passed through the two-stroke zone 748. It is determined whether there is a sphere (S503). If there is a game ball that has passed through the double hit zone 748 (S503: YES), the main control board 841 'releases the two variable winning devices 709a and 709b in synchronization (S504).

  If there is no game ball that has passed the two-stroke zone 748 (S503: NO), the main control board 841 ′ passes through the single shot zone 729 as to whether or not a game ball detection signal from the zone sensor 770a is input. It is determined whether there is a game ball that has been played (S505). If there is a game ball that has passed through the single hit zone 729 (S505: YES), the main control board 841 'opens one variable winning device 709b (S506).

  When there is no game ball that has passed through the single hit zone 729 (S505: NO) or after the processing of S502, S504, or S506, the main control board 841 'exits the privilege grant subroutine and returns to the game control main process. The variable winning devices 709a, 709b, and 709c have an opening time of about 0.5 seconds, and seven winning balls are paid out for each winning of the variable winning devices 709a, 709b, and 709c.

  In the pachinko machine 701 ′ of this modified example, as shown in FIG. 61, when the game ball bounced by the batter doll 723 ′ as the course changing member passes through the home run zone 759, the variable winning devices 709a, 709b, 709c are opened, The variable winning devices 709a and 709b are released when the two-stroke zone 748 is passed, and the variable winning device 709b is released when the single-stroke zone 729 is passed. Depending on whether the player enters the ball, the benefits obtained by the player change, the game becomes more complex, and the interest is improved. In addition, since a different privilege is provided for each of the plurality of entrances (home run zone 759, 2 strike zone 748, single hit zone 729), it is possible to give the player the expectation of entering the entrance more advantageous, This also makes it possible to improve the taste. Since benefits may or may not be granted when entering the entrance, benefits as expected by the player may be granted or benefits different from the player's expectation may be granted, It will improve your taste. Since there are a plurality of entrances, a privilege can be determined in advance for each entrance, and the privilege can be selected according to the entrance into which the game ball has entered. The player wishes to enter the entrance corresponding to the privilege he expects, but it does not always meet the expectation, so the preference is improved. Regardless of the type of entrance, all of the variable prize-winning devices 709a to 709c may be opened, and the bonus granting mode may be changed by changing the number of times and the opening time. For example, 3 times for the home run zone 759, 2 times for the 2-stroke zone 748, 1 time for the single-stroke zone 729, and 2 times for the home run zone 759, 1 second for the 2-stroke zone 748, In the single shot zone 729, it can be made variously such as 0.5 seconds. In these cases, the number of variable winning devices can be reduced. Since the batter 723 'changes the course of the game ball received from the game board 704', the play path of the game ball on the upper stage 746 'becomes complicated. If a plurality of ball inlets 750a 'and 750b' are provided, it is impossible to predict where to enter the ball. The upper stage 746 ′ has a structure for guiding the game ball from the upstream side to the downstream side, and the batter 723 ′ is arranged on the downstream side relative to the ball outlet 758 ′ so that the path of the game ball on the upper stage 746 ′ Is changed from the downstream side to the upstream side. For this reason, some of the game balls that play on the upper stage 746 ′ move from the upstream side to the downstream side, and some of the game balls change their course from the downstream side to the upstream side. Therefore, compared with the case where the game ball is simply guided from the upstream side to the downstream side, the path of the game ball becomes richer and the preference is enhanced. Further, a limited space on the game board can be effectively used by using a part of the center combination 706 'for the arrangement of the display surface. As described above, the main control board 841 'functions as a privilege giving means in cooperation with the variable winning devices 709a, 709b, 709c by executing a privilege granting subroutine. Since this privilege granting means grants a player a privilege on a game selected from a plurality of aspects, whether or not the grant can be determined by entering the receiving ball, the preference is enhanced.

  Note that when any two or more of the variable winning devices 709a, 709b, and 709c are opened, it is not always necessary to synchronize, and the opening time and the opening timing may be different from each other. You may provide the entrance (for example, "out" entrance) where a privilege is not provided. In addition, when the variable winning devices 709a, 709b, and 709c are not in operation, it may be possible or impossible depending on the arrangement of the nails.

(Second modification of software for a pachinko machine equipped with a central device of a seventh modification)
In this modification, the software of the first modification is changed. Accordingly, illustrations and descriptions of common parts are omitted as appropriate, and portions to be described are illustrated and described below. The game control main process executed by the main control board 841 ′ is the same.

  As shown in FIG. 64, in the privilege granting subroutine in the second modification, the main control board 841 ′ determines whether or not a game ball detection signal from the zone sensor 770c is input, that is, a game ball that has passed through the home run zone 759. It is determined whether or not there is (S701). If there is a game ball that has passed through the home run zone 759 (S701: YES), the main control board 841 ′ additionally lights up a maximum of three hold lamps 761 ′ within a range not exceeding the upper limit (four in this modification). (S702). Specifically, if the number of hold lamps 761 ′ that are already lit is 0 or 1, three hold lamps 761 ′ are additionally lit, and if two hold lamps 761 ′ are already lit, two hold lamps 761 ′. If there are three hold lamps 761 ′ that are already lit, one hold lamp 761 ′ is additionally lit. If all four hold lamps 761 ′ are already lit, no additional lamps are lit.

  Subsequently, the main control board 841 ′ makes a hit / miss determination for the number of the holding lamps 761 ′ additionally lit in S <b> 702 (S <b> 703). This determination is made based on the count value of the determination random number generation counter built in the main control board 841 ′. For example, if three hold lamps 761 ′ are turned on, the count value at that time is hit. A first determination is made based on whether or not the value matches the value, and a second determination is made based on whether or not a value obtained by adding 1 to the count value matches the winning value. A third determination is made depending on whether or not the value obtained by adding the value matches the winning value. Note that the determination method is not limited to this.

  Next, the main control board 841 'stores these determination results as reserved storage (S704). Note that the number of reserved memories is up to four, which corresponds to the number of reserved lamps 761 '. If there is no game ball that has passed through the home run zone 759 (S701: NO), the main control board 841 ′ does not execute S702 to S704, and whether or not the game ball detection signal from the zone sensor 770b is input, that is, It is determined whether or not there is a game ball that has passed through the two-stroke zone 748 (S705). If there is a game ball that has passed the double hit zone 748 (S705: YES), the main control board 841 ′ additionally lights up a maximum of two hold lamps 761 ′ within a range not exceeding the upper limit (four in this modification). (S707). Specifically, if two or less hold lamps 761 ′ are already lit, two hold lamps 761 ′ are additionally lit. If three hold lamps 761 ′ are already lit, one hold lamp 761 ′ is turned on. If the four hold lamps 761 ′ are already lit, the additional lighting is not performed.

  Subsequently, the main control board 841 ′ determines whether or not the holding lamp 761 ′ additionally lighted in S707 is hit based on the count value of the determination random number generation counter in the same manner as S703 described above (S708). The result is stored as a hold storage (S709). Then, after the process of S709 or when there is no game ball that has passed through the double hit zone 748 (S705: NO), the main control board 841 'exits the privilege granting subroutine and returns to the game control main process. In this way, if there is a game ball that has passed through the home run zone 759 or the two-stroke zone 748, a determination of a hit is made unless the reserved memory is full (four in this modification). Since it becomes easy to give the player a chance to start changing the symbol, and a chance to win a special game other than winning the starting entrance 707 ', that is, the possibility of a special game, can be prevented from becoming monotonous. In particular, when the number of reserved memories reaches a set value (for example, 3 or 4), if the symbol variation time is shortened or the probability that it is determined that the winning is improved, the player can easily obtain such benefits. The effect of preventing the game from becoming monotonous is great.

(Third modification of software for a pachinko machine equipped with a central device of a seventh modification)
In this modification, the software of the first modification is changed to the flowchart shown in FIG. 66, and the center accessory 706 ′ of the pachinko machine shown in FIG. 60 is replaced with the center accessory 706 ″ shown in FIG. This is almost the same configuration as the center combination 706 of the seventh modified form in FIG. 47, and the configuration other than the arrangement of the out zone and the hit zone is the same as that of the modified form. A double dash is attached to and a description thereof is omitted as appropriate.

  As shown in FIG. 65, the fence 728 ″ of the center actor 706 ″ is provided with an out zone 759 ″ and a hit zone 729 ″ corresponding to the entrance, and the upper stage 746 ″ is moved from the near side to the far side. Some of the moved game balls flow into either the out zone 759 ″ or the hit zone 729 ″. The game ball that has flowed into the hit zone 729 ″ is placed under the floor of the upper stage 746 ″. The game ball detected by the zone sensor 770 ″ (shown in parentheses in FIG. 65) and flowing into the out zone 759 ″ flows out to the back side of the game board 702 ″ as it is.

  Next, a privilege granting subroutine executed as a subroutine for the main control board 841 ″ as a subroutine for game control main processing (similar to the modification shown in FIG. 62 and not shown and described) will be described. As shown in FIG. In the privilege grant subroutine, the main control board 841 ″ determines whether there is a game ball detection signal from the zone sensor 770 ″, that is, whether there is a game ball that has passed the hit zone 729 ″ (S801). If there is no game ball detection signal from the zone sensor 770 "(S801: NO), the bonus control subroutine is exited and the process returns to the game control main process.

  As shown in FIG. 66, if there is a game ball that has passed the hit zone 729 "(S801: YES), the main control board 841" has a built-in lottery counter (the integer values from 0 to 9 are repeatedly counted in ascending order). A lottery is performed based on the count value (S802), the normal symbol display device 760 "is variably displayed, and the number corresponding to the count value is displayed statically (S803). Depending on whether or not (that is, based on the lottery result), the number of open variable winning devices 709a ", 709b", 709c "is determined (S804). That is, if the displayed number is 7, the variable winning devices 709a ", 709b", 709c "are released synchronously (S805), and if 5, the variable winning devices 709a", 709c "are released synchronously. (S806) If it is 3, the variable winning device 709b "is opened (S807). If it is other than 7, 5, or 3, nothing is performed and the privilege giving subroutine is exited and the game control main process is returned. Also, after executing any one of S805, S806, or S807, the privilege granting subroutine is exited and the process returns to the game control main process. The variable winning devices 709a ", 709b" and 709c "have the same opening time and number of winning balls as in the first modification.

  In this modified example, when the game ball passes the hit zone 729 ″, a lottery is performed, and the variable winning devices 709a ″, 709b ″, 709c ″ are released according to the lottery result, so that the benefits obtained by the player change However, the game becomes more complicated and the interest is improved. Note that the number of times of opening and the opening time may be varied depending on the lottery result. In the case of the number of times of opening, for example, if the lottery is 7, it will be 3 times, if it is 5, if it is 3, if it is once, if it is the opening time, for example, if it is 7, 2 seconds, 5 if 1 seconds, 3 if 0.5 seconds, etc. Can be various.

  Further, when any two or more of the variable winning devices 709a ″, 709b ″, and 709c ″ are opened, it is not always necessary to synchronize, and the opening time and the opening timing may be different from each other. The control board 841 ″ functions as a privilege granting means in cooperation with the variable prize winning devices 709a ″, 709b ″, 709c ″ by executing the privilege granting subroutine.

(Eighth modification of the central device 5)
67 to 72, the central device 805 which is the eighth modified form is movably disposed at the lower stage of the central device 505 which is the fifth modified form, and a drive mechanism for driving the stage is provided. It has been changed by removing the moving member, and in particular, the stage can be moved to a storage position for storing game balls on the stage and a release position for dropping the stored game balls to the board surface side. And The display surface of the display device is arranged inside the frame, and the discharge port is opened upward near the lower side of the display surface. Thereby, it is possible to enhance the interest of the ball game by changing the behavior of the game ball inside the central device, in particular, the fall position or the drop direction of the game ball. Accordingly, illustrations and descriptions of common parts are omitted as appropriate, and portions to be described are illustrated and described below. In the drawing, elements corresponding to the fifth modification form are described as being in the 800s by adding 300 to the same product number, and new elements are given new numbers.

  As shown in FIGS. 67 to 70, the left wall plate 834 a facing the frame body 832 is provided with a ball outlet 853 a on the upper side of the upper stage 846 and on the near side of the entry preventing member 826. Further, the upper stage 846 is provided with a discharge port 825 between the entry preventing member 826 and the back plate 834c. As shown in FIG. 68, the lower end of the warp hook 852b is connected to a holding portion 857 connected to the lower side of the discharge port 825, and the game ball that has entered the ball inlet 850b passes through the warp hook 852b to the holding portion 857. Carried.

  As shown in FIGS. 68 to 70, a discharge member 859 having an inclined surface 858 having a deep back side and a low front side is slidably inserted into the holding portion 857. The lower end of the discharge member 859 is connected to the plunger 847 of the electromagnetic solenoid 845. When the electromagnetic solenoid 845 is not energized, it is moved to the lowered position by the return spring 848 as shown in FIGS. When energized, the plunger 847 is pushed up to the raised position as shown in FIG. Therefore, when the release member 859 is in the lowered position, the game ball can be received and held in the holding portion 857 as shown in FIGS. 68 and 69. As shown, the game ball can be pushed up from the holding portion 857 and released to the front side of the entry preventing member 826.

  As shown in FIGS. 67 to 71, the lower stage 844 includes an inclined portion 846a, a concave portion 846b, an upper surface plate 864 having end portions 846c at the left and right ends, and a front plate 865 suspended therefrom. As shown in the figure, the upper surface plate 864 is provided with a central movement protrusion 866, a left movement protrusion 867, and a right movement protrusion 868 that protrude to the back side. On the other hand, as shown in FIG. 67, the vertical plate 844a of the upper stage 846 is provided with moving grooves 870a, 870b, 870c, and these central moving protrusion 866, left moving protrusion 867 and right moving protrusion 868 are inserted so as to be movable up and down. I am letting.

  As shown in FIGS. 69 and 70, the attachment portion 873 of the link member 872 is bonded to the central movement protrusion 866 of the lower stage 844. As shown in FIGS. 71 and 72, the link member 872 is provided with a long pin engagement hole 874, and a pin 876 erected on the cam disk 875 is inserted into the pin engagement hole 874. . An output shaft 879 of a motor 878 is fitted in the shaft fixing hole 877 of the cam disk 875, and the cam disk 875 is rotationally driven by the motor 878. 69 and 70, the motor 878 is fixed to the back surface of the vertical plate 844a of the upper stage 846 via mounting legs 871 (see FIG. 71 for the shape). With this configuration, as shown in FIGS. 72 (a), (b), and (c), when the motor 878 is operated, the cam disk 875 rotates, and the pin 876 moves along the circular path. As the pin 876 moves, the link member 872 moves up and down, and the lower stage 844 connected to the link member 872 moves up and down. The motor 878 is operated throughout the operation of the pachinko machine, and the lower stage 844 is repeatedly raised and lowered. In this modified embodiment, the attachment portion 873 of the link member 872 is bonded to the central moving projection 866 of the lower stage 844. However, as a connecting means for both the members 873 and 866, for example, various general means such as screwing and fitting can be used. The technology can be applied.

  In this pachinko machine, as shown in FIGS. 67 to 69, the game balls that have entered the ball inlet 850a of the central ornament portion 831b are discharged onto the upper stage 846 from the ball outlet 853a via the warp hook 852a. The game ball that has entered the ball entrance 850b is carried to the holding unit 857 via the warp rod 852b, and is released from the holding unit 857 through the discharge port 825 when the discharge member 859 is moved to the raised position by energizing the electromagnetic solenoid 845. Then, it gets over the entry preventing member 826 and falls onto the upper stage 846. At this time, the game ball released from the discharge port 825 appears as if it has jumped out of the display portion 838, and therefore, its behavior can be enhanced.

  The game ball that has reached the upper stage 846 via any path rolls on the upper stage 846 and falls onto the lower stage 844 and further falls downward from the lower stage 844. At this time, if the lower stage 844 is moved up and down as described above, when the lower stage 844 is lifted, the starting entrance 807 (not shown because it corresponds to the starting entrance 7 in FIG. 1). Although it is unlikely that a game ball that has fallen far from the lower stage 844 will win the starting entrance 807, when the lower stage 844 is at the descending end, for example, the distance from the starting entrance 807 becomes extremely short. There is a high possibility that the game ball dropped from the stage 844 will win the starting entrance 807. Therefore, the player will be delighted by comparing the path of the game ball on the upper stage 846 and the lower stage 844 with the lift position of the lower stage 844, and the pachinko game can be enhanced. Further, since the lower stage 844 is moved up and down, a pachinko game that is novel and highly attractive can be provided. Furthermore, if the player sees the state of the lower stage 844, it can be easily determined whether or not the player can easily win the starting entrance 807.

  The number of stages may be one or more, and only a part of a plurality of stages or a part obtained by dividing one stage into a plurality of parts may be moved. The drive mechanism can be realized by using transmission means such as an insulator, a gear, and a belt using, for example, a motor or a solenoid as a drive source. Of course, these are merely examples, and other configurations may be used. Examples of the moving direction of the stage include up-and-down movement, horizontal movement in the left and right and front and rear directions, and swing movement about a part of the stage, for example, the front end side. Also, the stage can be divided into a plurality of parts and each can be moved independently. For example, when moving up and down, it can be said that when the stage is lowered, the drop position from the stage is close to the lower prize-winning device, so that it is easy to win. In addition, for example, the stage can be divided into two parts, left and right, and moved as a whole into a V shape, or a horizontal or mountain shape. When the V shape is reached, the game ball accurately falls from the center. After all, it can be said that it becomes easier to win a prize apparatus below. Further, for example, when a set condition is satisfied or when a set game state (for example, time reduction or probability change) is reached, the stage is stopped at a position that is advantageous to the player or stays at such a position. You may lengthen the time. Alternatively, it may be movable between a storage position for storing game balls on the stage and a release position for dropping the stored game balls to the board surface side. Thereby, since a plurality of game balls can be temporarily stored and dropped at once, or the game balls can be dropped intermittently, it is possible to enhance the interest of the ball game. Further, the display unit 838 of the liquid crystal display panel is usually arranged inside the frame body 832 of the present modified embodiment, and the discharge port 825 opens upward near the lower side of the display unit 838. With such a configuration, the game ball released from the discharge port 825 appears as if it has jumped out of the display unit 838, so that its behavior can enhance interest.

(Modification of the central device of the eighth modification)
A central device 805 ′ shown in FIGS. 73 to 77, which is a modification of the eighth modification, is an example in which the lower stage is swung and a game ball is temporarily stored thereon. In addition, since the structure of a pachinko machine main body and a game board is the same as that of an 8th modification, illustration and description are abbreviate | omitted. Accordingly, illustrations and descriptions of common parts are omitted as appropriate, and portions to be described are illustrated and described below. In the drawing, elements corresponding to the eighth modification are described by adding dashes to the same product numbers and corresponding, and new elements are given new numbers.

  As shown in FIGS. 73, 74, 76 and 77, an upper stage 846 ′ which is a part of the frame 832 ′ is arranged inside the frame 832 ′, and the vertical plate 844a ′ of the upper stage 846 ′ is arranged. A moving groove 870a ′ is provided at the center. A rear opening 837 ′ is provided in the back plate 834c ′ of the frame body 832 ′, and a display portion 838 of a liquid crystal display panel 805a ′ (a main body portion is shown only in FIGS. 76 and 77) is provided in the rear opening 837 ′. 'Is inset. As shown in FIGS. 73 to 77, a wall outlet 834a 'on the left side of the frame 832' is provided with a ball outlet 853a 'that opens to the upper side of the upper stage 846'.

Therefore, when the electromagnetic solenoid 878 ′ is not energized and the plunger 879 ′ is lowered by the return spring 872 ′ as shown in FIG. 76, the lower stage 844 ′ swings on the drive protrusion 866 ′ side. The storage position is lower than the shafts 867 ′ and 868 ′ (the position at which the game ball mounting surface is inclined lower toward the back side). In this storage position, the game ball can be stored on the lower stage 844 'by the cooperation of the lower stage 844' and the vertical plate 844a 'as shown in FIG. On the other hand, when the electromagnetic solenoid 878 'is energized, the drive projection 866' is pushed up by the plunger 879 'as shown in FIG. 77, and the lower stage 844' is swung upward to the release position. Therefore, if a game ball is stored on the lower stage 844 ', the game ball is released from the storage by the lower stage 844' and falls.

  In this modification, the lower stage 844 ′ is normally set at the storage position, and each time a set number (seven in this modification) of game balls enter the ball inlets 850a ′ and 850b ′ (for example, the ball outlet 853a). The electromagnetic solenoid 878 'is energized to set the lower stage 844' as the discharge position (every seven game balls are detected by a sensor installed near ', 853b'). Further, when the time is short as described above, the lower stage 844 ′ is set to the discharge position almost in synchronization with the opening of the starting entrance 807 ′, so that the game ball dropped from the lower stage 844 ′ is the starting entrance 807. It will be extremely easy to win a prize.

  In this way, the stored game balls (which may not be stored depending on the game situation) are dropped from the lower stage 844 ′ at a stroke, so the possibility of winning the starting entrance 807 ′ is increased. , The player's expectation also increases. Further, since the game ball is stored on the lower stage 844 'and then dropped, a novel and highly interesting pachinko game can be provided. Furthermore, if the player sees the state of the lower stage 844 ', it can be easily determined whether or not the player can easily win the starting entrance 807'. Note that the timing and conditions for changing the lower stage 844 'between the storage position and the discharge position are merely examples, and may be changed at other timings and conditions.
