<P>PROBLEM TO BE SOLVED: To solve the following problem: a conventional Pachinko game machine has a symbol variable display device disposed roughly at the center of a game board surface, the display device being simply surrounded by center decoration generators, thereby causing the distribution of game balls along the board surface above the center decoration generators and the downflow track patterns of game balls passing around the center accessory generators to be monotonous. <P>SOLUTION: Outline members 46 (46A and 46B), and 47 of the center accessory generators provided around the symbol variable display are deformed periodically by a generator drive, so that the downflow track patterns, or so-called "ball paths", on the Pachinko game machine are variously changed, and the center accessory generators are periodically changed to be advantageously formed and disadvantageously formed to players. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention is provided so as to surround a variable symbol display device such as a liquid crystal display arranged almost at the center of the game board surface, and its contour portion acts as a guide wall for a game ball flowing down the game area in the game board surface. The present invention relates to a pachinko machine equipped with decorative objects.

  A variable display device made up of a liquid crystal display, digital display, reel display, etc. is arranged almost at the center of the game board surface in the current pachinko gaming machine, and its periphery is made of a synthetic resin called a center ornament. A center accessory in a form surrounded by an accessory is provided. This center accessory tends to increase in size rapidly in order to enhance the effect of the liquid crystal display or the like, and accordingly, the space for arranging the game nails on the game board surface is becoming narrower. Therefore, most of the game nails above the game board surface do not contribute to the diversification of the flow trajectory pattern of the game balls, so-called “ball stripes”, and the game balls launched above the game board Is merely dropped downward from the upper surface of the center ornament along the contours on both the left and right sides, and the flow pattern of the game balls on the upper and left and right sides of the center accessory is monotonous.

JP-A-10-277221

  For this reason, in Patent Document 2 below, in order to change the flow path pattern of the game ball in various ways, a flow path changing member that appears in a direction orthogonal to the game board surface is provided on the game board surface on the side of the center decoration accessory. A pachinko game machine provided is proposed. However, this flow path changing member can only change the local flow path, and cannot change the ball flow of the game balls launched into the game board surface over the entire game board surface. In addition, since the flow path changing member is configured to appear and disappear perpendicular to the game board surface, when the size of the flow path changing member is increased, there is a problem that the game ball is caught between the change member and the front glass and is stagnated.

On the other hand, in Patent Document 3 below, a seesaw-shaped guide member is arranged on the upper part of the center role of the game board surface, and the game balls launched at the substantially upper center of the game board surface are distributed to the left and right according to the game state. Pachinko machines with a configuration have been proposed. However, this pachinko machine automatically changes the inclination of the guide member to a predetermined inclination according to the gaming state, and distributes the game balls to the left and right so that it is always advantageous for the player. Thus, even if the game ball distribution on the upper part of the center role can be achieved, the pachinko gaming machine using the large liquid crystal display and the large center decoration feature targeted by the present invention is applied to the entire game board surface. There was a problem that it was impossible to realize the flow trajectory pattern of a wide variety of game balls.

JP 2004-121805 JP

The present invention was made paying attention to the problem of the ball flow in the game board surface in such a conventional pachinko gaming machine, and the contour part of the center decoration accessory arranged at the approximate center of the game board surface is periodically formed. By changing it, the player can change the game ball's left and right board sorting operation at the upper part of the center accessory and the flow pattern of the game ball passing through the left and right sides of the center ornament. It is intended to enhance the interest of pachinko machines by periodically changing to an advantageous form or an unfavorable form.

In order to solve the above-mentioned problem, the invention according to claim 1 includes a main control unit that controls the operation of an electrical gaming device provided in a game board, and a variable symbol display that is arranged substantially at the center of the game area of the game board. Device and a center ornament attached to the game board surface so as to surround the symbol variable display device, and an outer surface of the contour member constituting the upper surface and the left and right side surfaces of the center ornament accessory is A pachinko gaming machine comprising a ball guide wall in the gaming area, wherein the contour member has a structure that is at least partially displaceable along the gaming board surface, and is controlled by the main control unit It is driven at a constant cycle by the underlying accessory driving means. Note that the concept of the fixed period of the above configuration is not limited to, for example, the case where the contour member performs one reciprocating motion or one rotation and the operation time is one unit, and this is repeated with a constant periodicity. The invention also includes the concept of repeatedly executing a combination operation pattern of a plurality of operations or operation times having different reciprocation times or rotation times per unit as one unit. In addition, “under the control of the main control unit” means that it is under direct control as in the case of receiving a direct signal, or indirect control as in the case of being controlled by another control mechanism receiving the signal. It is meant to include both below.

According to this configuration, since the center ornament is periodically changed in shape, the game ball launched on the center ornament has a constant left-right distribution operation on the game board surface due to the deformation of the center ornament. The game ball that passes through both the left and right sides of the center ornament is changed in various ways along the left and right sides of the center ornament that changes constantly. Since the flow path pattern of the sphere is complicated, the playability can be further improved. Moreover, according to the present invention, when a player performs a fixed game with a handle using a game ball or a coin and the firing strength of the game ball is constant, the flow path of the game ball at any time due to a change in form of the center ornament Since the pattern changes, the player must always adjust the firing strength appropriately according to the change in the shape of the center ornament, and the pachinko machine's gaming intervention is maintained and fixed games are It has an effect that can be prevented.

  Claims 2 to 8 specify specific embodiments of the contour member of the center ornament in the pachinko gaming machine according to the present invention.

  In other words, in the embodiment shown in claim 2, the contour member located on the upper surface side of the center ornament accessory has a mountain shape in which at least a part thereof protrudes upward toward the game area side, which is an accessory. The driving means reciprocates in the left-right direction along the game board surface at a constant cycle.

  According to said structure, the mountain-shaped outline member located in the upper surface side of a center decoration accessory reciprocates to the left and right with a fixed period, and thereby the right and left ball flow of the center accessory in the said game area is Since the apex of the mountain-shaped outline part that can be distributed and the game ball is periodically moved, the player can adjust the launch intensity of the launcher while paying attention to the position of the apex. Is fostered.

  In the embodiment shown in claim 3, the contour members located on the left and right sides of the center decorative accessory have a shape in which at least a part thereof protrudes laterally toward the game area side, which is formed by the accessory driving means. It is reciprocated at a constant cycle in the vertical direction along the game board surface.

  According to the above configuration, the contour members on the left and right sides of the center ornament that is reciprocated in the vertical direction at regular intervals come into contact with the game balls flowing down the game area around the center ornament, Various changes can be made to the sphere flow.

  In the embodiment shown in claim 4, the contour members located on both the left and right sides of the center decoration accessory have a shape in which at least a part thereof protrudes laterally toward the game area side, and each of them is driven by an accessory. It is driven in the left-right asymmetric direction along the vertical direction by the means.

  According to such a configuration, the contour shape of the entire center ornament character becomes substantially asymmetric in the left-right direction, and the flow path of the game ball guided thereby becomes more diversified, and the player pays attention to the shape of the center ornament character. On the other hand, a new game characteristic is cultivated that adjusts the firing strength of the game ball while judging whether it is advantageous to pass the game ball through the left or right of the center role.

In the embodiment shown in claim 5, the contour member of the center ornament includes the first contour member located on the upper part of the ornament accessory and the second contour members located on the left and right sides of the ornament accessory, The contour members to be linked are connected in a link form, and at least one of these contour members is driven with a fixed period by the accessory driving means, so that the contour members are interlocked with each other and the entire center ornament accessory The shape changes.

  By adopting such a configuration, the center decorative accessory can be displaced in a constant cycle by synchronizing at least one of the contour members to the accessory driving means, and by synchronizing the other contour members connected by the link mechanism. Therefore, although the outline shape of the entire center ornament can be changed in a complicated manner, the apparatus can be configured at low cost.

In the embodiment shown in claim 6, the contour members located on the left and right sides of the center accessory are composed of a plurality of block bodies that can be displaced in the horizontal direction along the game board surface, and each block body has a predetermined phase shift. The outer shape of the contour member formed at the protruding end of each block body is changed by reciprocating in the horizontal direction at a constant cycle by the accessory driving means.

  According to such a configuration, since the contour shape of the both sides of the center decorative accessory is determined by the arrangement of the protruding ends of the block bodies, it is possible to realize a more complicated contour shape change. There is an advantage that the flow path of the game ball flowing down along the path becomes more complicated.

  In the embodiments of claim 7 and claim 8, the contour member of the center ornament is composed of a plurality of annular members having an arbitrary outer shape surrounding the design variable display device, and these are arranged in the thickness direction. By overlapping each other so that they can rotate independently, each annular member is rotated around the symbol variable display device in different directions by the accessory driving means, or rotated at different rotation cycles in the same direction. The outer peripheral shape obtained by synthesizing the contour of each annular member is changed.

  Such a center ornament accessory can realize a complicated contour shape change by rotating a plurality of annular members at a constant period by a driving means, and a flow pattern of a game ball that flows down while contacting this Can be increased.

  Furthermore, in the embodiment of claim 9, a through gate or a warp route entrance is provided in the middle of at least one of the plurality of flow paths of the game ball that change in contact with the contour member of the center ornament accessory. And a game ball entrance such as a general prize opening or a start opening.

    With such a configuration, along with the periodic change of the outer shape of the contour member of the center ornament accessory, the flow path pattern of the game ball inevitably changes periodically, and the probability of entering each entrance is It will be rich in change and will enhance the interest of the ball game.

  Furthermore, the invention according to claim 10 is the pachinko gaming machine according to any one of claims 1 to 9, wherein game nails are planted in a displaceable displacement region of the contour member and in the periphery of the displacement region. It is assumed that a non-nailing area that is not provided is provided.

  With such a configuration, the contour member can be suitably deformed, and it can be prevented that it becomes an obstacle to flow down on the board surface of the game ball.

FIG. 1 shows an overall configuration of a pachinko gaming machine 1 to which the present invention is applied.
A rectangular game board 2 is detachably held on the front surface of the game board holding frame 1 constituting the main body of the pachinko gaming machine. A front door 4 having a round window holding a two-piece transparent glass 3 is arranged in front of the game board 2, and the front door 4 is provided with hinges 5 and 5 provided at the left end of the game board holding frame 1. It is installed so that it can be opened and closed. At the lower part of the game board holding frame 1, an upper plate 6, a lower plate 7, a launch handle 8, and a pair of speakers 9, 9 are provided. In addition, a switch unit 10 having three push buttons used in a production game is attached to the front surface of the upper plate 6.

The game board 2 is provided with a guide rail 11 made of a metal band for guiding the shot ball that has been fired in an arc shape, and an area defined by the guide rail 11 is formed from a round window of the front door 4. It is configured as a visually recognizable game area 12.
A center accessory 13 is attached to the accessory attachment hole 2b provided substantially at the center of the game area 12 of the game board 2, and a symbol variable display device 14 comprising a liquid crystal display unit is disposed at the center of the center accessory 13. ing. In addition to the liquid crystal display unit, the symbol variable display device 14 provided in the center accessory 13 includes various examples such as an LED, a CRT, and a rotating drum. The outer peripheral portion of the center accessory 13 is constituted by a center ornament accessory 15 that forms a main part of the present invention. Details of the configuration of the center ornament accessory 15 will be described later.

A large number of game nails 16 are provided in the game area 12 at the upper part of the center accessory 13 to collide with the game balls B fired toward the game center B and distribute the game balls B. The game nails 16 are also arranged on the game board surface 2a below the center accessory 13, and the interval and arrangement thereof are appropriately set so that the game balls B passing through the game nails 16 perform unpredictable operations. .
On the other hand, a through gate 17 is provided in the game area 12 on the left side of the center accessory 13, and in the lower game area 12, a start winning opening 18, 19 having two upper and lower stages, a big winning opening 20, The normal winning openings 21, 22, 23, 24, the out holes 25, etc. are arranged. Furthermore, in the lower game area 12, the digital display 26 for a normal figure for displaying the result of the normal symbol lottery executed when the game ball B passes through the through gate 17, the start prize A special figure digital display 27 for displaying a result of a special symbol lottery executed when the ball enters the mouth 18.19 is arranged. In the figure, 28 is a leaf spring attached to the end of the guide rail 11 to prevent the game ball B launched into the game area 12 from flowing backward, and 29 is provided in the middle of the guide rail 11. Return rubbers 30 for causing the game ball B, which has been strongly launched into the game area 12, to collide and change the direction, are windmills arranged on the left and right of the center accessory 13.

A pachinko gaming machine to which the present invention is applied generally has the above-described configuration, and a player can use a launching handle 8
When the game ball B is launched into the game area 12 by operating the, the fired game ball B repeatedly collides with the game nail 16 planted in the game area 12, and the game area 12 cannot be predicted due to gravity. It flows down while drawing a simple downflow trajectory. At this time, the game balls B are distributed to the left and right of the game area 12 while being in contact with the upper surface of the center accessory 13. When the game balls B distributed to the left and right pass through the through gate 17, the game balls B pass through the through gate 17 by the action of the main control unit 70 (not shown) disposed on the back of the game board holding frame 1. The normal symbol lottery is executed at the timing of passing, and when this is won, the electric tulip 31 provided above the start winning opening 19 is opened for a predetermined time and the game ball B easily enters the starting winning opening 19 A state arises.

When a game ball B enters the start winning opening 18 or 19, a special symbol lottery is executed by the main control unit 70 in response to this, and when the special symbol lottery is won, The “big hit gaming state” is executed in which the large winning opening 20 is repeatedly opened a predetermined number of times.
The special drawing digital display 27 displays the lottery result regardless of the result of the lottery executed when the winning entrances 18 and 19 are entered. On the liquid crystal display unit provided at the center, the symbol variable display effect related to the lottery result is executed. In other words, when the special symbol lottery is won, after the symbol change display is performed on the liquid crystal display unit, a special symbol such as “7” (big hit symbol) is stopped and displayed after that 20 is opened and enters special gaming state. Even during the transition to the special game state, the liquid crystal display unit performs image display regarding the progress of the game state, round progress display for notifying the number of times the special winning opening 20 is opened, and the like.

As shown in FIGS. 1 to 3, the center accessory 13 is fitted with a frame member 35 of a center decorative accessory 15 made of synthetic resin in an accessory mounting hole 2b provided substantially at the center of the game board 2. The variable symbol display device 14 composed of a liquid crystal unit or the like is accommodated and held in a display device holding hole 36 provided in the center of the frame member 35.
The frame member 35 has a stage surface 37 to which the game ball B can be guided at a lower portion thereof, and the game ball B that has entered from the warp inlets 38 provided on both side surfaces passes through the warp passage 39 on the stage surface 37. It is supposed to move into. On the stage surface 37, a communication hole 40 into which the game ball B can enter is opened upward, and the game ball B that has entered the ball luckily here is from a discharge port 41 provided substantially on the same surface as the game board surface 2a. Although it is released to the game area 12, since this discharge port 41 is located immediately above the start winning port 18 provided on the game board surface 2a, it is possible to enter the starting winning port 18 with a very high probability. .
In addition, the game ball B that cannot roll into the communication hole 40 by rolling on the stage surface 37 is discharged from the discharge part 42 at the front end to the game area 12.

  In addition, on the outer peripheral portion of the center decoration accessory 15, nailed areas AL, AC, and AR are formed. The left nailed area AL is a nailed area provided in the left board surface area of the center decorative accessory 15, and is equivalent to one game ball from the movable area of the left contour member 46A protruding from the left board surface of the center decorative accessory. It is larger than the diameter and is about 1.5 balls wide. Similarly, the central nailed area AC is a nailed area provided in the upper part of the center decorative accessory 15, and is provided in the movable area of the upper contour member 47. The right nailed area AR is a nailed area provided in the right board surface area of the center decorative accessory 15, and is equivalent to one game ball from the movable area of the right contour member 46B protruding from the left board surface of the center decorative accessory. It is wider than the diameter and is about 1.5 balls wide. By providing the upper no-nail region, the upper contour member 47 and the obstacle nail 16 do not interfere with each other. Further, by providing the left nailed area AL and the right nailed area AR, the distance from at least the nail closest to the left and right contour member 46 is 1 to 1.5 balls, and the game sphere is defined as the contour member. There is no possibility that the game ball is stopped by being sandwiched between the obstacle nails or the contour member is damaged.

  Further, a fall prevention obstacle nail 16 ′ is disposed below the left non-nail area AL and the right non-nail area AR. This is a obstacle nail for changing the course of the game ball, although there is a possibility that a game ball that falls linearly in the no-nail region may be generated by providing the left and right no-nail region. In addition, the above-described windmill 30 is disposed below the non-nailed areas AL and AR so that the game balls whose course has been changed by the contour member can be appropriately distributed.

As shown in FIG. 3, the frame member 35 is formed with receiving recesses 43, 44, 45 on the upper and left and right sides, respectively, and each receiving recess 43, 44, 45 has a configuration described below. The shape changeable contour members 46 and 47 are accommodated.
First, the right and left contour members 46 and 46 and the upper contour member 47 all have similar forms, but here, the contour member 46 provided on the right side surface portion of the center decorative accessory 15 will be described as a representative example thereof. . The ribs 48 and 49 formed on the bottom of the housing recess 45 of the frame member 35 are rotatably supported at both ends of a screw shaft 50 having a helical gear portion 50a engraved on the outer periphery via a bearing member (not shown). . A nylon spur gear 51 is fixed to one end of the screw shaft.

FIG. 4 shows a cross-sectional view taken along the line IV-IV in FIG. A nylon spur gear 51 fixed to one end of the screw shaft 50 includes a spur gear 55 attached to an output shaft 54 of a stepping motor 53 fixed to the back of the game board 2 via a motor base 52, an idle gear 56, Meshed via 57. A female screw portion 59 of the moving bearing 58 is screwed into the helical gear portion 50a of the screw shaft 50. A sprocket 60 is rotatably supported on the moving bearing 58, and meshes with a synthetic resin chain 61 having one end fixed to the frame member 35. The other end of the chain 61 is connected to the chain 61 by a predetermined amount. It is connected to the frame member 35 via a spring 62 for applying tension. Note that the link plate 63 on the front side of the chain 61 shown in FIG. 2 has a substantially triangular shape, and serves to conceal the sprocket 60 from being exposed from the front of the gaming machine.

  As shown in FIG. 4, the center ornament accessory 15 is close to the transparent glass 3 (having a double glass structure) with a gap that prevents the game ball from flowing down. The game ball falls along the outer edge while colliding with the outer peripheral portion of the center ornament accessory 15 and the contour member.

Therefore, when the output shaft 54 of the stepping motor 53 is driven forward / reversely, the screw shaft 50 rotates forward / reversely in conjunction with this, and the moving bearing 58 and the sprocket 60 screwed to the screw shaft 50 are connected to the screw shaft 50. It is reciprocated along the length direction. The driving of the stepping motor 53 is controlled by the main control unit 70 so that the moving bearing 58 and the sprocket 60 reciprocate at a constant cycle.
Thus, along with the vertical movement of the moving bearing 58 and the sprocket 60, the chain 61 constituting the contour member 46 is deformed as shown in FIGS. 2 (a) and 2 (b), and the portion pushed outward by the sprocket 60 is the apex. As the slope of the upper part and the lower part changes every moment, the game ball B flowing down around the center accessory 13 flows down on both sides of the center accessory 13 along this, so that the flow path pattern changes at any time. It will be.

  Further, as shown in FIG. 2 (a), the movable region ML of the left contour member (the region indicated by the dashed line) and the movable region MR of the right contour member are upstream of the warp route 39 to the stage (game The contour member is deformed in this region. Further, the above-described nailless areas AL and AR are provided along the outer peripheries of the movable areas ML and MR. Further, in FIG. 2 (a), the following relationship is established with respect to the maximum deformation distance indicated by D, that is, the maximum difference between the distance when one end of the contour member is in the retracted position and the protruding position. . When the diameter of the game ball is d, the contour member is designed to be deformed in a range of 1 / 40d ≦ D ≦ 2d. This is because if D is smaller than this, the effect of changing the flow path of the sphere is diminished, whereas if it is larger, it is necessary to increase the movable region, and the degree of freedom in designing the gauge is reduced due to this relationship. Because it will do.

  The deformation speed of the contour member, that is, the speed at which the projecting state is changed from the retracted state is set to 1/2 d or less per minute, where d is the diameter of the game ball. This is because if the speed is higher than this, the flow of the game ball is affected too much, which may cause an obstacle to the game.

  The contour members 46A, 46B, 47 are deformed at a constant cycle, but the cycle is different for each contour member. For example, the left contour member 46A completes one cycle in 4 hours, the right contour member 46B in 6 hours, and the upper contour member 47 in 3 hours. That is, the time required to return to the same shape as when the power is turned on is after 12 hours which is the least common multiple of these. In addition, when the power is turned off and then turned on again, each contour member is controlled to return to a predetermined initial posture. The return to the predetermined initial posture is performed by detecting a position of a moving bearing 58 described later or a rotational position of the sprocket 60 by a photoelectric sensor (not shown) and correcting it to the initial position. If an advantageous shape in which the ball flow-down state is advantageous is defined as the initial posture, the advantageous state can be caused by the shape of the contour member when the power is turned on, and the fun of the game can be enhanced. Further, if the sensor position for initial position detection can be set and changed to a plurality of values, it is possible to freely change the setting of the advantageous time zone.

  In addition, although not shown in the drawing, the multi-color LED is arranged on the center ornamental accessory 15, and these light emission patterns are formed by a substrate (the effect lamp substrate 87 described later) under the control of the main control unit. It comes to control. These are controlled so as to change the light emission state intermittently or continuously corresponding to the deformation state of the contour member described above. These light emission states allow the player to know at a glance what the deformed state of the contour member, that is, the state of the game ball flow distribution state is. These light emission pattern controls function as deformation state suggesting means for suggesting the deformation state of the contour member, and this light emission pattern is stored in the ROM of the effect control board 73. In this embodiment, the light emission pattern control of these LEDs is shown as the deformation state suggestion means, but instead of this, on the symbol variable display device 14 (effect display device), the hitting points that provide an advantageous ball flow, etc. You may display.

  The configuration of the contour member 47 provided on the upper part of the center ornament accessory 15 is substantially the same as the configuration of the contour members 46 and 46 on the left and right sides, but a pulley 64 in which one end of the chain 61 is pivotally supported by the frame member 35. Only the point supported by is different from the configuration of the contour members 46 and 46. In the configuration of the contour member 47, members denoted by the same reference numerals as the contour member 46 indicate the same members, and the description thereof is omitted here.

  FIG. 5 shows a VV cross-sectional view in FIG. As shown in FIG. 5, a sprocket 60 is rotatably supported inside the moving bearing 58, and the link plate 63 is once screwed to the chain 61 to conceal each deformation mechanism of the contour member. It is like that. Further, as described above, the obstacle nail is implanted so that there is a gap of one game ball to 1.5 balls between the chain 61 in mesh with the sprocket 60 and the obstacle nail 16. . This is because the non-nailed areas AL, AC, and AR are provided as described above.

  Thus, the chain 61 constituting the contour member 47 is formed with a straight mountain-shaped inclined portion on the left and right with the portion pushed upward by the sprocket 60 as the apex, and along with the horizontal movement of the moving bearing 58 and the sprocket 60, Since the position of the apex is displaced in the left-right direction, the game ball B launched toward the upper part of the center ornament accessory 15 corresponds to the amount of deviation between the position flowing down from the gap of the game nail 16 and the position of the sprocket 60. To the left and right of the center role. Further, the game balls B distributed to the left and right are guided by the contour members 46 and 46 located on the left and right of the center ornament 15 and distributed as a more complicated flow path pattern.

Note that the sprocket 60 of the contour members 46 and 46 located on the left and right of the center decorative accessory 15 is when the sprocket 60 of one contour member 46 is lowered as shown in FIGS. 2 (a) and 2 (b). In the preferred embodiment, the sprocket 60 of the other contour member 46 is controlled so as to rise, and is controlled so as to move in a so-called asymmetric direction. This is one way to prevent the uniform flow pattern of the ball. For example, if these are controlled symmetrically, the player launches the game ball B to either the left or right of the game area 12. However, since the conditions are almost the same, the player periodically stops.
In that respect, if driving is performed so that the left and right are deformed asymmetrically, when either one of the contour members 46 is disadvantageous for the player, the other is advantageous for the player. If the nail 16 and each winning opening are arranged in a balanced manner, the player launches the game ball B aiming at an advantageous position, and can prevent hitting. Further, the sprocket 60 of the contour member 47 located on the upper part of the center decorative accessory 15 is also moved left and right in synchronization with the movement of the contour members 46, 46, or moved to the left and right at different periods, Complex flow path patterns can be realized.

  Thus, the contour members 46 and 47 of the center ornament 15 are individually driven, and each of them is deformed at a constant cycle, so that, for example, a through gate 17 is added to one of the complicated flow path patterns of the plurality of game balls B. If the entrances such as the warp route 39 and the like are arranged, the situation in which the entry can be made easily and the situation in which the entry is difficult occur periodically depending on the deformation mode of the contour members 46, 47. Taking the case of FIG. 1 as an example, if the apex of the contour member 46 located on the left side of the center decorative accessory 15 is rising, it becomes easy for a game ball to enter the left warp route entrance 38, When the apex of the contour member 46 located on the right side is lowered, it becomes difficult for the game ball to enter the warp route entrance 38 on the right side, so that the player can deform the contour members 46 and 47 of the center ornament accessory 15. While observing the aspect, it is necessary to adjust the launch handle 8 and launch the game ball B to an appropriate position.

FIG. 6 is a block diagram of a control system for carrying out the control of the pachinko gaming machine of the present invention.
The arrows in the figure indicate the direction of the control signal, and the power supply path to each board and a part of the state signal path unrelated to the present invention are omitted.
