Description

  The present invention relates to a ball game machine such as a pachinko machine or an arrangement ball machine.

  In a ball game machine such as a pachinko machine, an image display means such as a liquid crystal type is disposed in the approximate center of the game area on the front of the game board, and a symbol start winning means is provided in the center of the left and right sides below the image display means. The winning means are arranged one above the other, and a plurality of ordinary winning means are arranged adjacent to one side or both left and right sides thereof.

  The non-opening and closing type winning means such as the symbol starting winning means and the normal winning means include a mouth member that forms an upward winning opening on the front and rear surfaces of the mounting plate that contacts the front surface of the game board, and a game ball that has won from the winning opening. And a guide rod that guides the game board to the back side of the game board. The guide rod is inserted into the mounting hole and is attached to the game board from the front side.

  When such a non-opening and closing type winning means is adopted, generally two or three life nails are arranged above the entrance of the winning opening, and the game ball passing between the nail is the winning opening. To win a prize.

  In this type of winning means, the interval between the nail is very important in determining the winning rate of the game ball to the winning opening, and the adjustment work is very complicated and requires high skill. It has become. Various measures have been taken to facilitate this nail adjustment.

  For example, an adjustment plate provided with a plurality of adjustment portions corresponding to the distance between the left and right life nails in the vertical direction is provided on the front side of the mouth member of the winning means so that the vertical adjustment is possible. There is one in which the distance between the left and right life nails is changed (Patent Document 1).

JP-A-9-38280

  In this conventional winning means, the distance between the left and right life nails is changed by moving the adjustment plate in the vertical direction with respect to the mouth member, so that the handling during the adjustment is relatively easy. When the base side is not driven at an appropriate interval with respect to the game board, there is a problem that nail adjustment cannot be performed properly.

  For example, if the base side of the left and right life nails is an appropriate interval that is slightly larger than the diameter of the game ball, the game is performed by making the left and right life nails substantially parallel to the adjustment plate on the front side of the mouth member. The winning percentages of the game balls near the board and the glass plate can be adjusted to be substantially the same.

  However, if the distance between the bases of the left and right nail is sufficiently larger than the diameter of the game ball, even if the front plate side distance between the left and right life nails is adjusted to be small with the adjustment plate, it is still closer to the game board side. The ball that stops with the game ball resting on the nail if the front end side distance between the left and right nail is too small to reduce the win rate on the game board side. Problems such as stopping occur.

  Conversely, if the distance between the left and right life nails is smaller than the diameter of the game ball, the front end side distance between the left and right life nails is increased so that the ball stops near the game board. If it is going to prevent, there will be a problem that the winning rate of the game ball in the vicinity of the glass plate becomes large.

  In order to prevent ball stopping, etc., it is necessary to adjust one or both of the right and left life nails in an arc shape, etc., but the life nails that have already been driven into the game board are curved in an arc shape and adjusted. There is a problem that requires the most difficult skills to do.

  Therefore, in the conventional non-opening / closing type winning means or nail adjustment method, it is assumed that the base side of the life nail is a proper and proper interval, and as long as there is variation in the interval on the base side, it is easy to achieve an appropriate winning rate. There is a problem that it cannot be adjusted.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a ball game machine capable of appropriately and easily adjusting a winning rate of a game ball regardless of variations in obstacle means on the entry portion side. .

The ball supply tray 8 and the ball tray 9 are mounted on the front plate 6 and are covered with an upper plate cover 11 and a lower plate cover 12 from the front side.

  At the front center portion of the upper plate cover 11, a rotation effect means 13 that also functions as an operation button is disposed obliquely upward, and a chance button 14 is disposed on the left side thereof. As shown in FIG. 2, the glass door (viewing door) 5 includes a door frame 15 and a glass plate (transparent plate) 16 mounted on the back side of the door frame 15. A game board 17 is detachably attached to the front frame 4 on the back side of the glass door 5 so as to correspond to the glass door 5. The glass door 5 is an example of a visual door, and the glass plate 16 is an example of a transparent plate.

  As shown in FIG. 1, a guide rail 18 for guiding a game ball launched from the launching unit is arranged in a substantially arc shape on the front surface of the game board 17, and in a game area 19 inside the guide rail 18. Various game parts such as an image display means 20, a normal symbol starting means 21, a special symbol starting means 22, a variable winning means 23, a normal winning unit 24, a normal symbol displaying means 25, a special symbol displaying means 26, etc. are arranged. A large number of game nails are arranged between the game parts 20 to 26.

  In the lowermost part of the game area 19, an out port 27 for guiding the out ball to the back side is provided. The game area 19 is visible through the glass plate 16 of the glass door 5.

  The guide rail 18 has an outer rail 18a and an inner rail 18b. The image display means 20 is arranged in the upper part of the game center 19 in the left-right direction, and the special symbol starting means 22 and the variable winning means 23 are arranged vertically below the image display means 20. The normal winning unit 24 includes a plurality of non-opening / closing type winning openings as described later, and is provided on both the left and right sides of the variable winning means 23. The special symbol starting means 22 has a non-opening / closing type winning opening 22a and an opening / closing type winning opening 22b. The normal symbol starting means 21 is disposed between the image display means 20 and the guide rail 18.

  The image display means 20 includes an image display unit 28 such as a liquid crystal display, and a decorative frame 30 having a display window 29 corresponding to the image display unit 28 and mounted on the front surface of the game board 17. The decorative frame 30 is provided with a protruding portion 31 protruding forward from the game board 17 from the upper side to the left and right side portions, and a normal symbol display means 25 and a special symbol display means 26 on the front surface of the upper portion side of the protruding portion 31. And are attached.

  The normal symbol display means 25 is for variably displaying normal symbols, and is composed of a plurality of light emitting elements corresponding to a plurality of types of normal symbols (for example, two types of “O” and “X”). On condition that the starting means 21 detects a game ball, the two light-emitting elements blink for a predetermined time so that they are alternately turned on, and a random value lottery is selected in advance when the normal symbol starting means 21 detects a game ball. The light emitting element on the “◯” side in the hit state is turned on when the hit determination value is matched, and the light emitting element on the “×” side in the off state is turned on and stopped in other cases. In addition, the normal symbol after change will be in a hit mode with a predetermined probability of about 1/10.

  The special symbol display means 26 is constituted by a segment type or the like that can display the special symbols by changing the light emitting part. The special symbols change for a predetermined time on condition that the special symbol starting means 22 detects the game ball. Then, when the random number value drawn at the time of detection of the game ball by the special symbol starting means 22 coincides with a predetermined jackpot determination value, it is stopped in a predetermined jackpot mode, and in other cases it stops in a missed mode. It has become.

  The open / close type winning opening 22b of the special symbol starting means 22 is opened only for a predetermined time (short time) when the stop symbol after the fluctuation of the normal symbol display means 25 is in a hit state. The variable winning means 23 has an opening / closing plate 23a. When the special symbol after the change of the special symbol display means 26 becomes a big hit state and the special gaming state occurs, the opening / closing plate 23a opens to the front side and falls from above. To play game balls. During the special game state, when the predetermined time (for example, about 30 seconds) elapses from the opening of the opening / closing plate 23a, or when a predetermined number (for example, 10) of game balls wins, the operation of closing the opening / closing plate 23a is performed for one round. And this operation is continued a predetermined number of times (for example, 16 rounds).

  The image display unit 28 is at an appropriate timing according to the progress of the game, such as a change display of the effect symbols 33a, 33b, 33c corresponding to the special symbol of the special symbol display means 26, an operation instruction to display the operation instruction image 34 of the rotation effect means 13, and the like. Various effect images are displayed at any time. That is, when the special symbol is changed by the special symbol display means 26, one or a plurality of, for example, three effect symbols 33a to 33c are variably displayed on the image display unit 28 in synchronization with the change of the special symbol. At this time, the effect symbols 33a to 33c change for a predetermined time through a predetermined effect symbol variation pattern determined by lottery on the condition that the special symbol start means 22 detects the game ball, and then synchronize with the end of the variation of the special symbol. Stop sequentially in a predetermined order (for example, left, right, middle, etc.).

  The stop symbol after the change of the effect symbols 33a to 33c is a jackpot effect mode in which all the special symbols are stopped when the special symbol is stopped in the jackpot mode, and at least a part of the off symbol effect is different when the special symbol is stopped in the miss mode. It becomes an aspect.

  For example, numerical symbols from 0 to 9 are used for the production symbols 33a to 33c, and when the special symbols are stopped in a big win mode, the production symbols 33a to 33c are jackpot productions such as “7/7/7”. When it stops in the mode and the special symbol stops in the off mode, the effect symbols 33a to 33c stop in the off mode such as “2, 4, 5”.

  In the operation instruction of the rotation effect means 13, a predetermined game state that gives the player a sense of expectation, such as when a highly reliable effect symbol variation pattern in which the special symbol after variation becomes a big hit mode is drawn, for example, When the two effect symbols 33a and 33c except for one effect symbol 33b become the same reach, an operation instruction image 34 for instructing the operation of the rotation effect means 13 is displayed at a predetermined position of the image display unit 28. Is done.

  Then, for example, when the special symbol starting means 22 detects a game ball, lottery is drawn, and when a special game state occurs after the changed special symbol becomes a big hit mode, the operation instruction image 34 If the light emitting cover 35 of the rotation effecting means 13 is pressed at an appropriate timing during symbol variation according to the above, the light emitting portion in the light emitting cover 35 rotates in a blinking light emission state while rotating, and the special jackpot mode thereafter A notice of the suspension of the symbol and the occurrence of a special gaming state following this will be given.

  Note that the rotation effect means 13 may rotate the light regardless of whether or not the player operates. In addition, during rotation light emission of the rotation effect means 13, an effect image indicating the rotation light emission of the rotation effect means 13 may be displayed on the image display unit 28.

  As shown in FIGS. 3 and 4, the obstacle means 62, 63 includes one or two game nails 62 a, upstream of the unit nail row 41 a provided on the game board 17 near the upper side of the restriction means 64, 65. 63a and one game nail 62b, 63b provided on the game board 17 in the vicinity of the upper side of the mounting plate 43 on the opposite side of the reinforcing means 66, 67 with respect to the regulating means 64, 65, and its unit nail row Between the most upstream game nails 62a, 63a of 41a and the game nails 62b, 63b in the vicinity of the upper side of the mounting plate 43 are entry portions 60, 61 where game balls begin to enter the winning holes 38, 39.

  The game nails 62a and 63a and the game nails 62b and 63b constitute life nails arranged on both sides of the entry portions 60 and 61, and by adjusting the distance between the game nails 62a and 63a and the game nails 62b and 63b, It is possible to adjust the mouth width in the board surface direction of the game board 17 of the entry sections 60 and 61. Accordingly, the game nails 62a and 63a and the game nails 62b and 63b also constitute obstacle protrusions capable of adjusting the mouth width.

  Note that the entry portions 60 and 61 are disposed below the cut portion 41b between the unit nail rows 41a of the guide nail row 41 and below the unit nail row 41a on the downstream side, and open toward the cut portion 41b. ing.

  As shown in FIGS. 2 to 8, the restricting means 64 and 65 are disposed on the entry portions 60 and 61 side and project from the front surface of the game board 17 to the front side of the mounting plate 43, Inclined guide portions 64b and 65b that incline rearward from the lower ends of the restricting portions 64a and 65a to the front surface of the mounting plate 43 are provided above and below, and the lower ends thereof are integrally connected to the upper end of the mounting plate 43. The restricting portions 64a and 65a are disposed at the entrance portions 60 and 61 between the pair of game nails 62a, 62b, 63a and 63b or in the vicinity thereof.

  The restricting portions 64a and 65a have a flat front surface and project forward from the rear end edge of the entrance of the winning openings 38 and 39. Therefore, the front-rear width on the side of the entry portions 60, 61 formed between the pair of game nails 62a, 62b, 63a, 63b is restricted from the interval between the conventional game board 17 and the glass plate 16, and the restriction portions 64a, 65a. The game ball that has entered through the front side of the restricting portions 64a and 65a wins the winning openings 38 and 39.

  Note that the upper peripheral edges of the restricting portions 64a and 65a are appropriately chamfered to prevent cornering. The restricting portions 64a and 65a may have a structure that can limit the front-rear width of the entry portions 60 and 61, and the front surfaces thereof do not need to be flat. The back sides of the restricting portions 64a and 65a are hollow.

  As shown in FIGS. 2 to 8, the reinforcing means 66 and 67 have hollow box-like protrusions 66 a and 67 a that open to the rear side, and are located on the center side of the game area 19 with respect to the regulating means 64 and 65. The protrusions 66a and 67a are integrally formed on one end side of the restricting means 64 and 65, and the lower side is integrally formed on the upper end side of the mounting plate 43, respectively. The projecting bodies 66a and 67a have a projecting height that is the same as or slightly lower than the mouth members 44 and 45, and guide portions 66b that guide the game balls to the winning ports 38 and 39 on the restricting means 64 and 65 side. , 67b and retracting portions 66c, 67c that avoid interference with the side walls 44b, 45b of the mouth members 44, 45 are provided.

  The guide portions 66b and 67b are formed in a flat shape in the vertical direction, and are substantially flush with the inner surfaces of the side walls 44b and 45b of the mouth members 44 and 45. The guide portions 66b and 67b may slightly protrude from the inner surfaces of the side walls 44b and 45b of the mouth members 44 and 45 toward the winning ports 38 and 39, or may be provided slightly apart from the inner surfaces of the side walls 44b and 45b. Further, the guide portions 66b and 67b may be curved or bent in the protruding or recessed direction. The guides 66b and 67b are sufficient if they can guide the game ball to the winning prize openings 38 and 39. The upper ends of the restricting means 64 and 65 and the reinforcing means 66 and 67 are close to the lower side of the lowermost guide nail row 41 and are inclined along the inclination of the guide nail row 41.

  The left normal winning unit 24 is provided with an inclined guide stand 68 for guiding the game ball toward the guide nail row 41 side at the end opposite to the special symbol starting means 22. The normal winning unit 24 on the right side is also substantially the same as the first winning port 38 and the second winning port 39 side of the left normal winning unit 24.

  When playing a game with this pachinko machine, if a game ball is driven into the game area 19 of the game board 17 by the launching means, the game ball will fall in the game area 19 along the front surface of the game board 17 and the normal symbol starting means. 21, or wins one of the winning openings 38, 39, 40, the special symbol starting means 22, and the variable winning means 23 of the normal winning unit 24. The game balls that have fallen without winning in the winning openings 38, 39, 40, etc. are guided by the inner rail 18b and discharged from the out opening 27.

  When the normal symbol starting means 21 detects a game ball, the normal symbol of the normal symbol display means 25 fluctuates for a predetermined time and stops in either the specific mode or the non-specific mode. If the normal symbol stops in a specific manner, the open / close-type winning opening 22b of the special symbol starting means 22 is opened for a predetermined time. When a game ball wins in one of the two upper and lower winning holes 22a, 22b of the special symbol starting means 22, the special symbol on the special symbol display means 26 fluctuates for a predetermined time and is synchronized with the fluctuation of the special symbol. Thus, the effect symbols 33a to 33c of the image display means 20 vary in a predetermined effect symbol variation pattern.

  When the special symbol starting means 22 detects a game ball, for example, when the special symbol after the change is in a special mode and a special game in which a special gaming state occurs is drawn, during the change of the special symbol, When two effect symbols 33a and 33c of the effect symbols 33a to 33c displayed on the image display means 20 reach a reach for displaying the same symbol, the effect symbols 33a to 33c are displayed as indicated by dotted lines in FIG. In addition, an operation instruction image 34 for instructing an operation of the rotation effect means 13 is displayed on the image display means 20.

  If the player presses the rotation effect means 13 at an appropriate timing when the operation instruction image 34 is displayed, the rotation effect means 13 rotates and emits red light, and then the special symbol stops in a special manner. The notice effect such as notifying that the special gaming state will occur will be performed. Then, after the special symbol stops in a special mode, a special game in which the variable winning means 23 performs a predetermined opening / closing operation occurs. In this special game, the opening / closing plate 23a of the variable winning means 23 is opened to the front side, and the game ball falling from above is guided into the variable winning means 23 by the opening / closing plate 23a. It is possible to play the game in an advantageous state that is easy to play.

  If there is a game ball that falls between the image display means 20 and the inner rail 18b and falls on the guide stand 68 of the left normal winning unit 24, the game ball is, for example, along the lowermost guide nail row 41 or the like. While being guided to the center side of the game area 19, it falls from the interrupted portion 41 b to the inner rail 18 b, or falls from the interrupted portion 41 b and wins the first winning port 38 or the second winning port 39. Falls to the inner rail 18b without winning. The game ball that has fallen on the inner rail 18b is guided to the out port 27 along the inner rail 18b.

  For example, a game ball that wins the first winning opening 38 enters the lower side of the unit nail row 41a from the entry portion 60 between the upper and lower game nails 62a and 62b and collides with or collides with the guide portion 66b of the reinforcing means 66. Without winning, the first prize opening 38 is won. Then, the game ball that has won the first winning opening 38 is guided to the back side of the game board 17 through the guide passage 51 and the discharge passage 52 and discharged.

  When the game ball enters the entry portion 60 between the upper and lower game nails 62a and 62b, there is a restriction portion 64a of the restriction means 64 on the game board 17 side, and the game ball is on the game board 17 side between the game nails 62a and 62b. Since the restricting portion 64a restricts the front-rear width of the entry portion 60 toward the front side so as not to pass, the game ball always passes near the glass plate 16 side between the game nails 62a and 62b. Therefore, the nail adjustment (mouth width adjustment) of the pair of game nails 62a and 62b may be performed in consideration of the winning rate of the game balls near the glass plate 16 between the pair of game nails 62a and 62b. Such nail adjustment is possible, and the nail adjustment can be easily and appropriately performed regardless of variations in the distance between the bases of the game nails 62a and 62b.

  For example, when driving a pair of game nails 62a and 62b which are life nails into the game board 17, it is desirable that the distance between the base sides of the game nails 62a and 62b is appropriate. However, in practice, there may be some variation in the distance between the bases of the game nails 62a and 62b due to the nature of the game board 17 and the error of the nailing machine.

  However, by providing a restricting portion 64a of the restricting means 64 projecting forward from the front surface of the game board 17 on the game board 17 side, all game balls can pass between the game nails 62a and 62b closer to the game board 17 side. Without passing through the glass plate 16 side. Therefore, as shown in FIG. 9 (a), when the distance between the bases of the game nails 62a and 62b is sufficiently larger than the diameter of the game balls, the front sides of the game nails 62a and 62b approach at appropriate intervals. Conversely, as shown in FIG. 9B, when the diameter of the game ball is smaller than that shown in FIG. 9B, the pair of game nails 62a and 62b is arranged such that the front sides of the game nails 62a and 62b are separated at an appropriate interval. Both or one of them may be adjusted as appropriate.

  Therefore, when nailing the game nails 62a and 62b, high nailing accuracy is not required, and the nailing operation can be performed easily and efficiently. In addition, when adjusting the nail of the game nail 62a, 62b thereafter, the nail adjustment may be performed in consideration of the space on the front side of the game nail 62a, 62b. However, it is possible to easily and appropriately adjust without requiring a high skill for adjusting the nail.

  Further, since the restricting means 64 has a simple structure having a restricting portion 64a and an inclined guide portion 64b, it can be implemented easily and inexpensively. Moreover, since the reinforcing means 66 is provided on the downstream side of the restricting means 64, and the restricting means 64 is reinforced by the reinforcing means 66, the restricting means 64 protrudes upward from the mounting plate 43. The damage of the restricting means 64 before assembly can be reduced.

  Further, since the reinforcing means 66 is provided with a game ball guiding portion 66b, even when the game ball rebounds toward the reinforcing means 66, the game ball can be promptly guided to the first winning opening 38. . Further, the restricting means 64 and the reinforcing means 66 are integrally provided on the mounting plate 43, and the first port member 44 having the first winning port 38 is mounted on the front surface of the mounting plate 43, so that the first port member 44 is mounted on the mounting plate. There is an advantage that the structure can be simplified as compared with the case where it is integrally formed with 43.

  FIG. 10 illustrates a second embodiment of the present invention. In this embodiment, the restricting means 65 is provided in a protruding shape on the upper side of the mounting plate 43. The restricting means 65 has a larger width on the lower side than on the upper side. Thus, by increasing the left and right width of the lower side of the restricting means 65, the attachment strength of the restricting means 65 itself to the attachment plate 43 is improved, and the reinforcing means 67 in the first embodiment can be omitted. In this embodiment, a game nail 63c is provided in place of the reinforcing means 67.

  In this embodiment, the side edge of the restricting means 65 on the side of the game nail 63b has a recessed portion 65c that is recessed in a square shape, and the game nail 63b is disposed in the recessed portion 65c. For this reason, the top side of the restricting portion 65a of the restricting means 65 can be disposed between the pair of game nails 63a and 63b. Other configurations are the same as those of the first embodiment.

  11 and 12 illustrate a third embodiment of the present invention. In this embodiment, the obstacle means 62 including three game nails (life nails) 62 a to 62 c is arranged corresponding to the normal winning means 69 on the game board 17 on the upper side of the normal winning means 69. The normal winning means 69 includes a mounting plate 43 mounted on the game board 17 and a mouth member 44 mounted on the front surface of the mounting plate 43 and having a winning port 38.

  The game nails 62a to 62c of the obstacle means 62 constitute obstacle protrusions whose distances can be adjusted. The attachment plate 43 is integrally provided with a restricting means 64 disposed between the three game nails 62a to 62c. The restricting means 64 has recesses 70a to 70c corresponding to the game nails 62a to 62c, and a restricting portion 64a is provided on the entry portion 60 side between the game nails 62a to 62c. Other configurations are the same as those of each embodiment.

  Thus, also when arrange | positioning the three game nails 62a-62c, it can implement similarly to each embodiment by arrange | positioning the control means 64 between each game nail 62a-62c.

  13 and 14 illustrate a fourth embodiment of the present invention. In this embodiment, the normal symbol starting means 21 is employed. The normal symbol starting means 21 is provided with a vertical passage port 72 and a start detection switch 74 for detecting a game ball passing through the passage port 72 in a protruding portion 73 protruding from the front surface of the mounting plate 43. A game ball passes through the passage 72 from the top to the bottom on the front side.

  Three (or two) game nails 62a to 62c corresponding to the passage opening 72 are provided on the game board 17 above the normal symbol starting means 21, and are located between the game nails 62a to 62c. The restricting means 64 is provided so as to protrude upward from the mounting plate 43. Other configurations are the same as those of each embodiment.

  Thus, even in the case of the normal symbol starting means 21 having the passage port 72, the restricting means 64 that protrudes upward from the mounting plate 43 can be integrally provided in the same manner as each embodiment.

  15 to 17 illustrate a fifth embodiment of the present invention. In this embodiment, the restricting means 64, 65 are a protruding plate 64d protruding in a trapezoidal shape upward from the mounting plate 43 of the normal winning means 69, and a plurality of vertical protrusions 64e in the left-right direction on the front side of the protruding plate 64d.
