In the following description, the ball passage formed in the back mechanism board will be described mainly with reference to the drawing of the posture as seen from the rear. It will be described as a method.

上部裏機構盤40は、この機構盤の基体となるベースフレーム40Aと、ベースフレーム40Aの上部に取り付けられた球貯留払出アッセンブリ40B、及び球貯留払出アッセンブリ40Bの下側に位置してベースフレーム40Aの下部に取り付けられた球通路アッセンブリ40Cからなり、ベースフレーム40Aに球貯留払出アッセンブリ40B及び球通路アッセンブリ40Cが組付けられて一体の上部裏機構盤40が形成される。   The upper back mechanism board 40 is positioned below the base frame 40A as a base of the mechanism board, the ball storage / dispensing assembly 40B attached to the upper part of the base frame 40A, and the ball storage / discharging assembly 40B. The ball storage assembly 40C and the ball storage assembly 40B and the ball assembly 40C are assembled to the base frame 40A to form an integrated upper back mechanism board 40.

ベースフレーム40Aは、平坦な支持プレート部と、この支持プレート部の外周に曲げ起こし成形されたリブ、支持プレート部の右側縁上下に形成された上部裏機構盤ヒンジ43などからなり、球貯留払出アッセンブリ40B及び球通路アッセンブリ40Cの前方全体を一体的に覆うように、これらのアッセンブリ40B,40Cの後方からの投影形状よりも大きめの逆L字状に形成されている。ベースフレーム40A各部には、球貯留払出アッセンブリ40B及び球通路アッセンブリ40Cをネジ固定するための雌ネジ部、ベースフレーム40Aを前枠後面側に閉止保持させるためのナイロンファースナー49の装着孔などが形成されており、例えば板厚1.2〜2.3mm程度の鋼板を、打ち抜き、曲げ、バーリング及びタッピング加工し、並びにヒンジピンをカシメ固着等して図示する形状に成形し、必要に応じてクロメート処理等の表面処理を施して構成される。   The base frame 40A includes a flat support plate portion, ribs bent and formed on the outer periphery of the support plate portion, upper back mechanism board hinges 43 formed above and below the right edge of the support plate portion, and the like. In order to integrally cover the entire front of the assembly 40B and the ball passage assembly 40C, they are formed in an inverted L shape larger than the projected shape from the rear of the assemblies 40B and 40C. Each part of the base frame 40A has a female screw part for screwing the ball storage / dispensing assembly 40B and the ball passage assembly 40C, a mounting hole for the nylon fastener 49 for closing and holding the base frame 40A on the rear side of the front frame, and the like. For example, a steel plate with a thickness of about 1.2 to 2.3 mm is punched, bent, burred and tapped, and the hinge pin is caulked and formed into the shape shown in the figure, and if necessary, chromate treatment, etc. Constructed with surface treatment.

球貯留払出アッセンブリ40Bは、遊技球を貯留する貯留タンク部を有し球払出装置の取り付けベースともなるアッセンブリベース41を基体とし、ここにタンクレール部の上方を覆うレールカバー、遊技球の払い出し処理を行う球払出装置42、遊技球の流下を規制可能な球止め機構(不図示)などが取り付けられて構成される。アッセンブリベース41には、遊技球を貯留する貯留タンク部41a、貯留タンク部41aと滑らかに繋がって貯留タンク部に貯留された遊技球を1列に整列させて下方の球払出装置42に導くタンクレール部41b、球払出装置42を着脱可能に装着保持する機構装着部41cなどが設けられており、例えば導電性のフィラーを混入した樹脂材料を用いて一体に成型される。   The ball storage / dispensing assembly 40B has a storage tank portion for storing game balls and has an assembly base 41 serving as a mounting base for the ball dispensing device as a base. Here, a rail cover that covers the upper portion of the tank rail portion, and a game ball payout process And a ball stop mechanism (not shown) capable of restricting the flow of the game ball are attached. The assembly base 41 includes a storage tank portion 41a for storing game balls, and a tank that is smoothly connected to the storage tank portion 41a and that aligns the game balls stored in the storage tank portion in a row and guides them to the lower ball payout device 42. A mechanism mounting portion 41c that detachably mounts and holds the rail portion 41b and the ball payout device 42 is provided, and is integrally molded using a resin material mixed with a conductive filler, for example.

貯留タンク部41aは、平面視横長で上面及び右面開放の箱状をなし底面が緩く右傾してタンクレール部41bに繋がっている。タンクレール部41bは、貯留タンク部41aの前後の壁面と滑らかに繋がって通路幅が徐々に狭くなるように形成され、底面は貯留タンク部よりも幾分大きな傾斜角をもって右傾して形成される。タンクレール部41bの下流部では通路幅が遊技球の直径よりもわずかに大きい程度のU字溝状になっており、貯留タンク部41aから供給された遊技球を整列させる整列通路が形成される。整列通路の上方にはこの通路を上下に重なって流下する遊技球を平らに均す重錘式の球均し振り子が揺動自在に枢支され、整列通路の下流端部には球払出装置42の導入口に繋がる出口開口が形成されている。このため、貯留タンク部41aに貯留された遊技球がタンクレール部41bを流下する過程で1列に整列され、出口開口から球払出装置42の導入口に導かれる。   The storage tank portion 41a is horizontally long in a plan view and has a box shape with an upper surface and an open right surface, and the bottom surface is gently inclined to the right and is connected to the tank rail portion 41b. The tank rail portion 41b is formed so as to be smoothly connected to the front and rear wall surfaces of the storage tank portion 41a so that the passage width is gradually narrowed, and the bottom surface is inclined to the right with a somewhat larger inclination angle than the storage tank portion. . In the downstream portion of the tank rail portion 41b, a U-shaped groove having a passage width slightly larger than the diameter of the game ball is formed, and an alignment passage for aligning the game balls supplied from the storage tank portion 41a is formed. . Above the alignment passage, a weight-type ball leveling pendulum that flattens the game balls flowing down with this passage vertically is pivotally supported, and a ball dispensing device is provided at the downstream end of the alignment passage. An outlet opening connected to the inlet 42 is formed. For this reason, the game balls stored in the storage tank portion 41a are aligned in a row in the process of flowing down the tank rail portion 41b, and are led from the outlet opening to the introduction port of the ball dispensing device 42.

球払出装置42は、外周に遊技球を受け入れる球受容溝を有して左右に延びる軸まわりに回動可能に設けられたスプロケット状の球送り回転盤と、この球送り回転盤を正・逆方向に回転駆動する球払出モータ、球送り回転盤及び球払出モータを収容するハウジングなどを主体として構成され、機構装着部41cに着脱可能に装着されて係止保持される。ハウジングの上端部にはタンクレール41bの出口開口と連絡して遊技球を受け入れる導入口が開口形成され、ハウジングの下端部には、後方に第1球払出口、前方に第2球払出口が前後に並んで開口形成されている。   The ball payout device 42 has a ball receiving groove for receiving a game ball on its outer periphery, and is provided with a sprocket-like ball feed rotating disk provided so as to be rotatable about an axis extending in the left and right directions. A ball payout motor that rotates in a direction, a ball feed rotating disk, a housing that houses the ball payout motor, and the like are mainly configured, and are detachably attached to and held by the mechanism mounting portion 41c. An inlet for receiving a game ball is formed at the upper end of the housing so as to communicate with the outlet opening of the tank rail 41b, and a first ball outlet for the rear and a second ball outlet for the front are formed at the lower end of the housing. Openings are formed side by side.

球払出装置42では、導入口から導入された遊技球がハウジング内で球送り回転盤の球受容溝に受け入れられ、球送り回転盤の回動方向に応じてハウジング内を後方または前方に転動してハウジング下端の第1球払出口または第2球払出口から払い出される。例えば、球払出モータが正転され球送り回転盤が正方向(図10に示す側面視において時計廻り、以下同じ)に回動されると、球送り回転盤の球受容溝に受け入れられた遊技球が球送り回転盤の回動とともにハウジング内を時計廻りに転動し、ハウジングの下端部後方の第1球払出口から払い出される。また球払出モータが逆転され球送り回転盤が逆方向(図10に示す側面視において反時計廻り、以下同じ)に回動されると、球受容溝に受け入れられた遊技球が球送り回転盤の回動とともにハウジング内を反時計廻りに転動し、ハウジングの下端部前方の第2球払出口から払い出される。   In the ball dispensing device 42, the game ball introduced from the introduction port is received in the ball receiving groove of the ball feed rotating disk within the housing, and rolls backward or forward in the housing depending on the rotation direction of the ball feeding rotating disk. Then, it is paid out from the first ball payout outlet or the second ball payout outlet at the lower end of the housing. For example, when the ball payout motor is rotated forward and the ball feed rotating disk is rotated in the forward direction (clockwise in the side view shown in FIG. 10, the same applies hereinafter), the game received in the ball receiving groove of the ball feeding rotating disk The ball rolls clockwise in the housing along with the rotation of the ball feed rotating disk, and is paid out from the first ball payout outlet behind the lower end of the housing. When the ball dispensing motor is reversed and the ball feed rotating disk is rotated in the reverse direction (counterclockwise in the side view shown in FIG. 10, the same applies hereinafter), the game ball received in the ball receiving groove is With this rotation, the inside of the housing rolls counterclockwise and is paid out from the second ball outlet in front of the lower end of the housing.

球払出装置42は、下部裏機構盤50に取り付けられた球払出制御基板82により作動が制御され、球払出制御基板82から入力された指令信号に基づいた回動方向及び回動角度で球送り回転盤か回転作動される。本実施形態では、所定の入賞条件が成立したときに球送り回転盤を時計廻りに回動させて後方の第1球払出口から遊技球を払い出させ、所定の球抜き操作が行われたときに球送り回転盤を反時計廻りに回動させて前方の第2球払出口から遊技球を排出させるように構成した例を示している。   The operation of the ball dispensing device 42 is controlled by a ball dispensing control board 82 attached to the lower back mechanism board 50, and the ball feeding device 42 is fed in a rotation direction and a rotation angle based on a command signal input from the ball dispensing control board 82. Turntable or turn-operated. In the present embodiment, when a predetermined winning condition is satisfied, the ball feeding rotary disk is rotated clockwise to pay out the game ball from the first first ball payout outlet, and a predetermined ball removing operation is performed. There is shown an example in which the ball feeding rotary disk is sometimes rotated counterclockwise to discharge the game ball from the front second ball outlet.

球通路アッセンブリ40Cは、全体として前後方向幅が比較的厚く左右方向幅が薄い矩形断面で上下方向に長い桟状をなし、上下の端部が左方に屈曲されて背面視コの字状に形成されている。球通路アッセンブリ40Cは、左側面が開放されて内部に前後2列の屈曲した通路溝が形成された通路形成部材44と、この通路形成部材の開放面を覆う通路カバー45などからなり、球払出装置42から払い出された遊技球を前後2列の球通路に沿って転動流下させ、下端の第1出口または第2出口に導出させる。   The ball passage assembly 40C as a whole has a rectangular cross section with a comparatively thick front-rear width and a thin left-right width, and has a vertically long cross-section. The upper and lower ends are bent leftward to form a U-shape when viewed from the back. Is formed. The ball passage assembly 40C is composed of a passage forming member 44 having a left side opened and formed with two front and rear bent passage grooves, a passage cover 45 covering the open surface of the passage forming member, and the like. The game balls paid out from the device 42 are caused to roll down along two front and rear rows of ball passages and are led out to the first outlet or the second outlet at the lower end.

通路形成部材44には、図10に示すように、前後に蛇行しつつ上下に延びるS字状の中央通路壁44cと、この中央通路壁44cの前方及び後方(図10における左側と右側)に遊技球の直径よりも幾分大きめの間隔をおいて略平行に上下に延びる前方通路壁44f及び後方通路壁44rを有し、中央通路壁44cを挟んで前後に各1列の平断面視凹状の通路溝を形成する。そして通路形成部材44の開放面に通路カバー45を取り付けることで2列の球通路46,47が背面視において前後に重複して形成され、左右方向の幅が球通路1列分の幅に抑制された球通路アッセンブリ40Cが構成される。   As shown in FIG. 10, the passage forming member 44 has an S-shaped central passage wall 44c that meanders back and forth while extending vertically, and forward and rearward (left and right sides in FIG. 10) of the central passage wall 44c. It has a front passage wall 44f and a rear passage wall 44r extending up and down approximately parallel to each other with a space slightly larger than the diameter of the game ball, and each row of concave portions in a plan view in front and rear with the central passage wall 44c in between. The passage groove is formed. Then, by attaching the passage cover 45 to the open surface of the passage forming member 44, two rows of spherical passages 46, 47 are formed overlapping in the front-rear direction in the rear view, and the width in the left-right direction is suppressed to the width of one row of the spherical passages. A ball passage assembly 40C is formed.

前述した球払出装置42の第1球払出口及び第2球払出口は、球通路アッセンブリ40Cの上端部において開口する球通路46の入り口(第1球入り口)46a、及び球通路47の入り口(第2球入り口)47aの配設位置に合わせて形成されており、本実施形態においては後列側の球通路が遊技球を上下の球皿6,7に導く球払出通路L6の下降通路(球払出下降通路)46、前列側の球通路が遊技球を機体の外部に導く球排出通路L7の下降通路(球抜き下降通路)47になっている。   The first ball discharge outlet and the second ball discharge outlet of the ball discharge device 42 described above are the entrance (first ball entrance) 46a of the ball passage 46 opened at the upper end of the ball passage assembly 40C, and the entrance ( It is formed in accordance with the arrangement position of the second ball entrance) 47a, and in this embodiment, the ball passage on the rear row side is a descending passage (ball) of the ball payout passage L6 that guides the game balls to the upper and lower ball dishes 6, 7. The pay-out descending passage (46) and the ball passage on the front row side are a descending passage (ball withdrawal descending passage) 47 of the ball discharge passage L7 for guiding the game balls to the outside of the machine body.

球通路アッセンブリ40Cは、球入り口の直下で右斜め下方に屈曲され、通路形成部材44の右側面が、ベースフレーム40Aの右側縁(すなわち球貯留払出アッセンブリ40Bの右側への最大張り出し位置)に合わせて形成されている。またベースフレーム40Aの左側縁は右側にオフセットされた球通路アッセンブリ40Cの左側面に合わせて形成されており、球払出装置42よりも下側の上部裏機構盤40の幅が上方の幅よりも狭く構成されている。   The ball passage assembly 40C is bent right diagonally downward just below the ball entrance, and the right side surface of the passage forming member 44 is aligned with the right edge of the base frame 40A (that is, the maximum protruding position to the right side of the ball storage and discharge assembly 40B). Is formed. The left side edge of the base frame 40A is formed to match the left side surface of the ball passage assembly 40C offset to the right side, and the width of the upper back mechanism board 40 below the ball dispensing device 42 is larger than the upper width. It is narrowly configured.

球通路アッセンブリ40Cの上下中間部では、球抜き下降通路47と球払出下降通路46とが中央通路壁44cを挟んで隣接し、前後平行に複数回折り返されてS字状に蛇行形成されている。このため、これらの下降通路46,47を転動流下する遊技球の速度を過度に増加させることがなく、静粛かつ滑らかに流下させ得るとともに、複数列の球通路でありながら簡明な構造で前後方向の厚さを最小限に抑えた構成になっている。通路形成部材44の溝底面(右側面)には、長孔状の監視窓が形成され遊技球の球流れを視認可能になっている。   In the upper and lower intermediate portions of the ball passage assembly 40C, the ball removal lowering passage 47 and the ball dispensing lowering passage 46 are adjacent to each other with the central passage wall 44c interposed therebetween, and are bent back and forth in parallel to form a serpentine shape in an S shape. . For this reason, the speed of the game balls rolling down the down passages 46 and 47 does not increase excessively, and can flow down quietly and smoothly, and it has a simple structure with a simple structure even though it is a plurality of ball passages. It has a configuration that minimizes the thickness in the direction. A slot-like monitoring window is formed on the groove bottom surface (right side surface) of the passage forming member 44 so that the ball flow of the game ball can be visually recognized.

球通路アッセンブリ40Cの下部は、左斜め下方に折り曲げられて傾斜通路とされ、球通路アッセンブリ40Cの下端部に下方に開く第1球出口46b,第2球出口47bが形成される。球払出下降通路46の出口である第1球出口46bと、球抜き下降通路47の出口である第2球出口47bとは、前後方向及び左右方向ともににオフセットされており、傾斜通路が短く形成された球抜き下降通路47の第2球出口47bが前方右側に、傾斜通路が長く形成された球払出下降通路46の第1球出口46bが後方左側に位置して互い違いに配設される。   The lower part of the spherical passage assembly 40C is bent obliquely downward to the left to form an inclined passage, and a first spherical outlet 46b and a second spherical outlet 47b that open downward are formed at the lower end of the spherical passage assembly 40C. The first ball outlet 46b, which is the outlet of the ball paying down passage 46, and the second ball outlet 47b, which is the outlet of the ball lowering passage 47, are offset both in the front-rear direction and in the left-right direction, so that the inclined passage is short. The second ball outlets 47b of the ball removal descending passages 47 are arranged on the front right side, and the first ball outlets 46b of the ball paying down passages 46 formed with the long inclined passages are located on the rear left side and are alternately arranged.

球貯留払出アッセンブリ40B及び球通路アッセンブリ40Cは、それぞれベースフレーム40Aの上部及び下部にネジ固定され、遊技球の貯留、払出、球止め及び球抜き機能を備えた上部裏機構盤40が形成される。上部裏機構盤40は、ベースフレーム40Aの右側縁に設けられた上部裏機構盤ヒンジ43,43と、前枠2の右側縁上部に取り付けられた前枠側上ヒンジ金具23,23の、ヒンジピンとピン受容孔との嵌合を利用して前枠2の後面側に着脱可能に装着され、ヒンジ連結された状態で後方に横開き開閉可能に配設される。   The ball storage / dispensing assembly 40B and the ball passage assembly 40C are screwed to the upper and lower portions of the base frame 40A, respectively, to form an upper back mechanism board 40 having a function of storing, dispensing, stopping and removing the ball. . The upper back mechanism board 40 includes hinge pins of upper back mechanism board hinges 43 and 43 provided at the right edge of the base frame 40A and front frame side upper hinge fittings 23 and 23 attached to the upper right edge of the front frame 2. And the pin receiving hole are detachably mounted on the rear surface side of the front frame 2 and are arranged so as to be opened and closed laterally rearward in a hinged state.

上部裏機構盤40は、上記のように上部裏機構盤40を前枠2の後面側にヒンジ連結させた状態で、上部裏機構盤40の上端(ベースフレーム40Aの上端)が外枠1における上枠杆の内面の高さ位置よりも低く、上部裏機構盤40の下端(球通路アッセンブリ40Cの下端)が収容枠に収容された遊技盤10の下端面と略同一の高さ位置に配設されるように構成されている。   In the state where the upper back mechanism board 40 is hinged to the rear side of the front frame 2 as described above, the upper back mechanism board 40 has the upper end (the upper end of the base frame 40A) at the outer frame 1. The lower end of the upper back mechanism board 40 (the lower end of the ball path assembly 40C) is arranged at a height position substantially the same as the lower end face of the game board 10 housed in the housing frame. It is comprised so that it may be installed.

このように、球通路アッセンブリ40Cでは、球払出下降通路46と球抜き下降通路47とを前後に重ねて配設することにより球通路アッセンブリ40Cの幅を球通路1列分の幅に抑制し、さらにこれらの球通路を上部裏機構盤40の右側縁に合わせて右方にオフセットして下降させることで、上部裏機構盤40の幅を更に狭く、具体的には球通路2列分の幅にも満たない寸法内で構成している。このため上部裏機構盤40の前方に位置する遊技盤10の後方に広いスペースを確保することができ、例えば、遊技盤10に配設される図柄表示装置を大型化し、あるいは各種入賞装置の選択や配置の自由度を拡大し、または化粧板11の裏面側に取り付けられる各種回路基板の大きさや配設位置の自由度を拡大することができる。   In this way, in the ball passage assembly 40C, the ball discharge lowering passage 46 and the ball removal lowering passage 47 are disposed so as to overlap in the front-rear direction, thereby suppressing the width of the ball passage assembly 40C to the width of one row of the ball passages. Further, these ball passages are lowered to the right by being aligned with the right edge of the upper back mechanism board 40, thereby lowering the width of the upper back mechanism board 40, specifically, the width of two rows of the ball passages. It is constituted within the dimension which is less than. For this reason, a wide space can be secured behind the game board 10 located in front of the upper back mechanism board 40. For example, the symbol display device arranged on the game board 10 can be enlarged or various winning devices can be selected. Further, the degree of freedom of arrangement can be expanded, or the size of various circuit boards attached to the back side of the decorative board 11 and the degree of freedom of arrangement position can be increased.

上部裏機構盤40の下側に設けられる下部裏機構盤50は、図6に球払出制御基板82及び電源基板83が装着された状態の背面図を示し、図13にこれらの回路基板82,83を取り外した状態の背面図(部分断面図)を示すように、この機構盤の基盤となる下部ベース51を主体として構成される。   The lower back mechanism board 50 provided on the lower side of the upper back mechanism board 40 is shown in a rear view in a state where the ball payout control board 82 and the power supply board 83 are mounted in FIG. 6, and FIG. As shown in a rear view (partial cross-sectional view) in a state where 83 is removed, the lower base 51 serving as a base of the mechanism panel is mainly configured.

下部ベース51は、この部材の基板となるベースプレート部51aと、ベースプレート部51aの右端部に前方に膨出成型されたヒンジ台座51b、ベースプレート部51aの前面側に形成された集合樋56(56L,56R)、ベースプレート部51aの後面側に形成された基板装着部などを主体として構成され、ベースプレート部51aを挟む前面側に主として遊技球を流下させる球処理関係の構造、後面側に主として回路基板を搭載する基板関係の装着構造が設けられる。下部ベース51は、例えば導電性のフィラーを混入して導電性を持たせた樹脂材料を用い、射出成型等の成形手段で一体に形成される。   The lower base 51 includes a base plate portion 51a serving as a substrate of the member, a hinge base 51b bulging forward at the right end portion of the base plate portion 51a, and a collecting rod 56 (56L, 56) formed on the front side of the base plate portion 51a. 56R), which is mainly composed of a board mounting portion formed on the rear surface side of the base plate portion 51a, and has a ball processing-related structure in which game balls mainly flow down to the front side sandwiching the base plate portion 51a, and a circuit board mainly on the rear surface side. A mounting structure related to the board to be mounted is provided. The lower base 51 is integrally formed by a molding means such as injection molding using, for example, a resin material that is made conductive by mixing a conductive filler.

ベースプレート部51aは、全体として背面視矩形で横長の扉状をなし、周縁にはベースプレート部を取り囲むリブが後方に突出して成型されている。ヒンジ台座51bは、正面視における形状が縦長矩形で前方に突出するブロック状に形成されており、このヒンジ台座51bの前面側上下には下部裏機構盤ヒンジ54を固定するためのネジ受容孔が形成され、台座内部にはネジ受容孔の後方に位置してネジ受容ボス及びこのネジ受容ボスを補強するリブが形成されている。   The base plate portion 51a as a whole has a rectangular shape in a rear view and has a horizontally long door shape, and a rib surrounding the base plate portion protrudes rearward at the periphery. The hinge pedestal 51b has a vertically long rectangular shape in front view and is formed in a block shape projecting forward. Screw receiving holes for fixing the lower back mechanism board hinge 54 are provided on the front and upper sides of the hinge pedestal 51b. A screw receiving boss and a rib for reinforcing the screw receiving boss are formed in the pedestal so as to be positioned behind the screw receiving hole.

集合樋56は、ベースプレート部51aから前方に突出して成型された左右の壁面56L,56Rを主体として構成される。これらの左右の壁面56L,56Rは、図13中の部分断面に壁面の形成位置及び形状を示すように、全体として上方の開口幅が広く下端の球排出口58に向けて幅が狭くなるV字状に形成されており、下部裏機構盤50を前枠後面側に閉鎖した閉鎖姿勢において、前後の前枠2及びベースプレート部51aと左右の壁面56L,56Rとの間に遊技球を流下させる遊技済み球排出通路57が形成される。   The collecting rod 56 is mainly composed of left and right wall surfaces 56L and 56R which are formed to protrude forward from the base plate portion 51a. These left and right wall surfaces 56L and 56R have a wide upper opening width as a whole and a narrower width toward the lower ball discharge port 58, as shown in the partial cross section in FIG. In a closed posture in which the lower back mechanism board 50 is closed to the rear side of the front frame, the game balls flow down between the front and rear front frames 2 and the base plate portion 51a and the left and right wall surfaces 56L and 56R. A played ball discharge passage 57 is formed.

集合樋56における左右壁面の上端の形成位置は、遊技領域PAを入賞装置に落入することなく落下してアウト口18から排出されるアウト球の排出位置、及び遊技領域PAを転動落下する途中で入賞装置に落入し入賞球導出孔を通って化粧板11の裏面側に導かれたセーフ球の排出範囲(例えば、詳細図示省略するが、化粧板11の裏面にネジ固定されセーフ球を集合させる球寄せカバーの排出開口範囲)をカバーするとともに、前述した上部裏機構盤40の第1及び第2球出口46b,47bの排出範囲を含むように設定されている。一方、集合樋56の下端部では、下部裏機構盤50の閉鎖姿勢において球排出口58の前方に位置して、左右の壁面56L,56Rの間に滑らかに張り出す整流突起28が前枠2から後方に突出して形成されている。   The formation positions of the upper ends of the left and right wall surfaces of the collective basket 56 fall without dropping the game area PA into the winning device, and the position where the out ball discharged from the out port 18 is discharged and the game area PA rolls and drops. The discharge range of the safe sphere that falls into the winning device on the way and is guided to the back side of the decorative board 11 through the winning sphere outlet hole (for example, although not shown in detail, the safe sphere is screwed to the back of the decorative board 11 and screwed. Is set to include the discharge ranges of the first and second ball outlets 46b and 47b of the upper back mechanism board 40 described above. On the other hand, at the lower end portion of the collecting rod 56, the rectifying projection 28 that is positioned in front of the ball outlet 58 in the closed posture of the lower back mechanism panel 50 and smoothly projects between the left and right wall surfaces 56L, 56R is the front frame 2. It protrudes backward from.

このため、上下の裏機構盤40,50を閉鎖した遊技状態において、遊技盤10から排出された遊技済み球(アウト球及びセーフ球)、及び後に詳述する上部裏機構盤40の球抜き下降通路47を通って第2球出口47bから排出された遊技球が、集合樋56の左右の壁面56L,56Rに受け止められて遊技済み球排出通路57に集合され、下部の整流突起28により落下速度が低減されるとともに斜め後方に誘導されて、下端の球排出口58から遊技施設側の遊技球回収装置に向けて排出される。   For this reason, in the gaming state in which the upper and lower back mechanism boards 40, 50 are closed, the game-completed balls (out balls and safe balls) discharged from the game board 10 and the lower back mechanism board 40, which will be described in detail later, are lowered. The game balls discharged from the second ball outlet 47b through the passage 47 are received by the left and right wall surfaces 56L, 56R of the collective basket 56 and gathered in the game-completed ball discharge passage 57. Is reduced and is guided obliquely backward and discharged from the ball discharge port 58 at the lower end toward the game ball collecting device on the game facility side.

ベースプレート部51aの後面側には、シールド板81を着脱可能に係止保持するシールド板装着構造52と、透明な樹脂ケースに収められた球払出制御基板82及び電源基板83を各々着脱可能に係止保持する基板装着構造53とからなる基板装着部が形成されている。   On the rear surface side of the base plate portion 51a, a shield plate mounting structure 52 for detachably engaging and holding the shield plate 81, a ball payout control board 82 and a power supply board 83 housed in a transparent resin case are detachably connected. A substrate mounting portion is formed which includes a substrate mounting structure 53 that holds and holds.

シールド板装着構造52は、微弱な制御信号を取り扱う球払出制御基板82の前方に形成されており、図13中に略示するように、ベースプレート部51aから側断面視T字状に後方に突出成型したシールド板支持脚52aと、ベースプレート部51aが背面視コの字状に切り離されて前後に弾性変形可能な楔状のロックアーム部52bとからなり、シールド板81に形成した矩形ダルマ穴状の支持脚受容スロットをシールド板支持脚52aに係合させて左方にスライドさせたときに、シールド板支持脚52aと支持脚受容スロットが係合し、ロックアーム部52bがシールド板のアーム受容孔に嵌入して、シールド板81を係止保持可能になっている。   The shield plate mounting structure 52 is formed in front of a ball payout control board 82 that handles weak control signals, and protrudes rearward from the base plate portion 51a in a T-shape in a side sectional view as schematically shown in FIG. The shield plate supporting leg 52a is formed into a rectangular dharma hole shape formed on the shield plate 81. The shield plate support leg 52a and the base plate portion 51a are cut into a U-shape when viewed from the back, and are wedge-shaped lock arm portions 52b that can be elastically deformed in the front and rear directions. When the support leg receiving slot is engaged with the shield plate support leg 52a and slid leftward, the shield plate support leg 52a and the support leg receiving slot are engaged, and the lock arm portion 52b is the arm receiving hole of the shield plate. The shield plate 81 can be locked and held.

シールド板81の左右方向寸法は球払出制御基板82の幅寸法よりも大きく形成されており、シールド板81及び球払出制御基板82を基板装着部に装着した状態でシールド板81の左端側が基板ケースよりも左方に延びて配設され、後面側が開放された放熱部81hが形成されるようになっている(図6を参照)。放熱部81hの左端上部は一部が切り起こされて差し込み型接続端子(例えばUL規格におけるE78965等)の雄型端子形状に設定された接続端子部81tが形成されており、アース線の端末に圧着された雌型の差し込み型接続端子を嵌合接続することで、比較的微弱な制御信号を取り扱う球払出制御基板82の前方全体を確実にアース電位に地落させて安定かつ十分なシールド効果を得られるようになっている。シールド板81は、例えば板厚0.8〜1.2mm程度の鋼板を打ち抜き、曲げ加工等して図示する形状に成形し所要の表面処理を施して構成される。   The horizontal dimension of the shield plate 81 is formed larger than the width dimension of the ball payout control board 82, and the left end side of the shield plate 81 is the board case when the shield board 81 and the ball payout control board 82 are mounted on the board mounting portion. Further, a heat radiating portion 81h is formed so as to extend leftward and open on the rear side (see FIG. 6). A part of the upper left end of the heat dissipating part 81h is cut and raised to form a connecting terminal part 81t which is set to a male terminal shape of a plug-in connecting terminal (for example, E78965 in UL standard). By fitting and connecting the crimped female plug-in connection terminals, the entire front of the ball payout control board 82 that handles relatively weak control signals is surely grounded to the ground potential, thereby providing a stable and sufficient shielding effect. Can be obtained. For example, the shield plate 81 is formed by punching a steel plate having a thickness of about 0.8 to 1.2 mm, forming it into a shape as illustrated by bending, and performing a required surface treatment.

基板装着構造53は、例えば図13における球払出制御基板82の装着部に示すように、ベースプレート部51aから側断面視L字状に後方に突出成型したベース側フック部53aと、ベースプレート部51aが背面視コの字状に切り離されて前後に弾性変形可能なロックアーム部53bとからなり、基板ケースの前面側に突出成型した側断面視逆L字状(または舌片状)のケース側レール部をベース側フック部53aに係合させて左方にスライドさせたときに、ロックアーム部52bがケース側レール部の右側端部と係合して球払出制御基板82を係止保持可能に構成される。   For example, as shown in the mounting portion of the ball payout control substrate 82 in FIG. 13, the substrate mounting structure 53 includes a base side hook portion 53 a that is projected rearward from the base plate portion 51 a in an L shape in a side sectional view, and a base plate portion 51 a. The case side rail is formed in a reverse L-shape (or tongue-like shape) as viewed from the side, and is formed of a lock arm portion 53b that is cut into a U-shape when viewed from the rear and elastically deformable in the front-rear direction. The lock arm portion 52b engages with the right end portion of the case side rail portion so that the ball payout control board 82 can be locked and held when the portion is engaged with the base side hook portion 53a and slid leftward. Composed.

また図13における電源基板83の装着部に示すように、ベースプレート部51aに、電源基板83の基盤ケースから前方に突出して形成された舌片状の支持脚を受容して支持する支持脚受容穴53cと、支持脚固定ネジを受容するネジ受容孔53dとを形成し、電源基板の支持脚を支持脚受容孔に嵌入支持させて支持脚受容孔53dに支持脚固定ネジを螺合締結することで電源基板83を係止可能な装着構造などが適用される。   Further, as shown in the mounting portion of the power supply board 83 in FIG. 13, a support leg receiving hole for receiving and supporting a tongue-like support leg formed to protrude forward from the base case of the power supply board 83 to the base plate portion 51a. 53c and a screw receiving hole 53d for receiving the support leg fixing screw, and the support leg of the power supply board is inserted and supported in the support leg receiving hole, and the support leg fixing screw is screwed and fastened to the support leg receiving hole 53d. A mounting structure that can lock the power supply board 83 is applied.

そして、ヒンジ台座51bの前面に下部裏機構盤ヒンジ54,54をネジ固定し、シールド板81をシールド板装着構造52に装着することで、ベースプレート部51aの前面側に主として遊技球を流下させる球処理関係の構造、後面側に主として回路基板を搭載する基板装着関係の構造を有する下部裏機構盤50が形成される。下部裏機構盤50は、下部ベース51の右側縁上下に設けられた下部裏機構盤ヒンジ部54,54と前枠2の右側縁上下に取り付けられた前枠側下ヒンジ金具24,24の、ヒンジピンとピン受容孔との嵌合を利用して前枠2の後面側に着脱可能に装着され、ヒンジ連結された状態で後方に横開き開閉可能に配設される。   Then, the lower back mechanism board hinges 54 and 54 are screwed to the front surface of the hinge base 51b, and the shield plate 81 is attached to the shield plate attachment structure 52, whereby the game ball mainly flows down to the front side of the base plate portion 51a. A lower back mechanism board 50 having a processing-related structure and a substrate mounting-related structure in which a circuit board is mainly mounted on the rear side is formed. The lower back mechanism board 50 includes lower back mechanism board hinges 54 and 54 provided above and below the right edge of the lower base 51 and front frame side lower hinge fittings 24 and 24 attached above and below the right edge of the front frame 2. It is detachably mounted on the rear surface side of the front frame 2 by utilizing the fitting of the hinge pin and the pin receiving hole, and is arranged so that it can be opened and closed laterally rearward while being hinged.

下部裏機構盤50は、下部裏機構盤50を前枠2の後面側にヒンジ連結させた状態で、下部裏機構盤50の上端(下部ベース51の上端)が収容枠に収容された遊技盤10の下端面(化粧板11の下端面)よりも下方に位置し、下部裏機構盤50の下端が外枠1における幕板の上面よりも上方に位置するように構成している。このため、上部裏機構盤40を開放すれば下部裏機構盤50を前枠2に閉止させた状態のままで、遊技盤10を収容枠に着脱することができる。   The lower back mechanism board 50 is a game board in which the lower back mechanism board 50 is hinged to the rear side of the front frame 2 and the upper end of the lower back mechanism board 50 (the upper end of the lower base 51) is housed in the housing frame. 10 is located below the lower end surface (lower end surface of the decorative plate 11), and the lower end of the lower back mechanism panel 50 is positioned above the upper surface of the curtain plate in the outer frame 1. For this reason, if the upper back mechanism board 40 is opened, the game board 10 can be attached to and detached from the housing frame while the lower back mechanism board 50 is kept closed by the front frame 2.

そして、上記のように前枠2の後面側に開閉可能にヒンジ連結された上部裏機構盤40及び下部裏機構盤50を前枠2の後方を覆うように閉止し、上部裏機構盤40の上部に設けられたナイロンファースナー49、下部裏機構盤50の左部に設けられたナイロンファースナー59を押圧ロックすることで、上下の裏機構盤40,50が前枠2の後面側に閉鎖状態で係止保持される。   Then, the upper back mechanism board 40 and the lower back mechanism board 50 that are hingedly connected to the rear side of the front frame 2 as described above are closed so as to cover the rear of the front frame 2, and the upper back mechanism board 40 The upper and lower back mechanism boards 40, 50 are closed to the rear side of the front frame 2 by pressing and locking the nylon first fastener 49 provided at the upper part and the nylon first fastener 59 provided at the left part of the lower back mechanism board 50. It is locked and held in the state.

一方、下部裏機構盤50の前方に位置する遊技補助盤20の後面側に、前枠2から後方に突出して賞球連絡バケット25が膨出成型され、その前方に閉鎖保持される上球皿6のあて板61から後方に突出して上球皿連絡ダクト65が成型されている。   On the other hand, on the rear side of the game assisting board 20 located in front of the lower back mechanism board 50, the prize ball connecting bucket 25 protrudes rearward from the front frame 2 and is bulged and held in front of the upper ball dish. An upper ball tray connecting duct 65 is formed so as to protrude rearward from the six contact plates 61.

賞球連絡バケット25は、収容枠よりも後方の上面と前枠2を貫通する前面とが開放された上面及び前面開放の箱状に形成されており、この賞球連絡バケット25の内側に、左右の側壁及び底壁に囲まれた断面視U字溝状の賞球連絡通路26が形成される。賞球連絡通路26は、一定の通路幅で前後方向に延びる誘導通路部26aと、この誘導通路部26aと繋がり通路幅が前方に向けて拡大する拡大通路部26bとからなり、誘導通路部26aの後端に形成された側断面視R状の誘導壁26r、及びこの誘導壁26rと滑らかに繋がって前方に下傾する底壁により誘導通路部26aに受容した遊技球を前枠2の前面側に流下させるようになっている。   The prize ball communication bucket 25 is formed in a box shape with an upper surface opened from the upper surface behind the housing frame and a front surface penetrating the front frame 2 and a front open box shape. A prize-ball connecting passage 26 having a U-groove shape in cross section, which is surrounded by the left and right side walls and the bottom wall, is formed. The prize ball communication passage 26 includes a guide passage portion 26a that extends in the front-rear direction with a constant passage width, and an enlarged passage portion 26b that is connected to the guide passage portion 26a and expands the passage width toward the front, and the guide passage portion 26a. The front wall of the front frame 2 receives the game ball received in the guide passage portion 26a by the guide wall 26r formed in the rear end of the side cross section R-shaped and the bottom wall smoothly connected to the guide wall 26r and tilted downward. It is designed to flow down to the side.

賞球連絡バケット25の形成位置は、上下の裏機構盤40,50が前枠に閉鎖保持された状態において、賞球連絡バケット25が集合樋の左右の側壁56L,56Rの間に突出して賞球連絡通路26が遊技済み排出通路57の上部に位置し、誘導通路部26aの後端部(誘導壁26r)が球払出下降通路46の第1球出口46bの直下に配設され、球抜き下降通路47の第2球出口47bが賞球連絡通路26の右側方に配設されるように設定されている(図12中に二点鎖線で付記する第1球出口46b、第2球出口47bを参照)。   The prize ball contact bucket 25 is formed in such a manner that the prize ball contact bucket 25 protrudes between the left and right side walls 56L, 56R of the assembly basket in a state where the upper and lower back mechanism panels 40, 50 are closed and held by the front frame. The ball communication passage 26 is positioned above the game-exited discharge passage 57, and the rear end portion (guide wall 26r) of the guide passage portion 26a is disposed directly below the first ball outlet 46b of the ball payout lowering passage 46. The second ball outlet 47b of the descending passage 47 is set so as to be disposed on the right side of the prize ball communication passage 26 (the first ball outlet 46b and the second ball outlet indicated by a two-dot chain line in FIG. 12). 47b).

このため、上下の裏機構盤40,50が前枠に閉鎖保持された状態では、球払出下降通路46の第1球出口46bから落下した遊技球は、遊技済み球排出通路56に流入することなく誘導通路部26aの後端部に流入して賞球連絡通路26を前方に流下する一方、球抜き下降通路47の第2球出口47bから落下した遊技球は、賞球連絡バケット25の右側方を落下して集合樋の右側壁面56Rに受け止められ、遊技済み球排出通路56を流下して下端の球排出口58から遊技施設側の球回収装置に排出される。   For this reason, in a state where the upper and lower back mechanism boards 40 and 50 are closed and held in the front frame, the game balls that have fallen from the first ball outlet 46 b of the ball pay-out descending passage 46 flow into the game-completed ball discharge passage 56. Without flowing into the rear end portion of the guide passage portion 26a and flowing down the prize ball communication passage 26, the game ball falling from the second ball outlet 47b of the ball removal descending passage 47 is placed on the right side of the prize ball connection bucket 25. The ball falls down and is received by the right wall surface 56R of the collective basket, flows down the game-completed ball discharge passage 56, and is discharged from the ball discharge port 58 at the lower end to the ball collection device on the game facility side.

賞球連絡バケット25の前方に位置する上球皿連絡ダクト65は、前後面が開放された角形ダクト状に形成されており、この上球皿連絡ダクト65の内側に上下左右の通路壁に囲まれて前後に延びる上球皿通出通路66が形成される。上球皿通出通路66の通路幅は、拡大通路部26bの前端の開口幅よりも幾分大きめに形成されるとともに、底壁が後方の拡大通路部26bと前方の球皿部64との間を繋いで前方に下傾して形成されている。   The upper ball tray connecting duct 65 located in front of the prize ball connecting bucket 25 is formed in a square duct shape with the front and rear surfaces open, and is surrounded by upper, lower, left and right passage walls inside the upper ball tray connecting duct 65. Accordingly, an upper ball tray passage 66 extending forward and backward is formed. The upper ball tray outlet passage 66 has a passage width slightly larger than the opening width at the front end of the enlarged passage portion 26b, and a bottom wall formed between the rear enlarged passage portion 26b and the front ball tray portion 64. It is formed by tilting forward and connecting between them.

上球皿連絡ダクト65の底壁は、誘導通路部26aの前方への延長線(賞球連絡バケット25の左側壁内面の延長線)よりも外側に位置する後部領域が一部斜めに切りかかれるとともに、左側壁がこれに合わせて切り欠かれており、上球皿6の閉鎖姿勢において、遊技補助盤20の前面側に、左斜め下方に開く開口部67が形成されるようになっている。   The bottom wall of the upper ball tray connecting duct 65 is partly cut obliquely at the rear region located outside the extension line to the front of the guide passage portion 26a (extension line of the inner surface of the left side wall of the prize ball connecting bucket 25). At the same time, the left side wall is cut out accordingly, and in the closed position of the upper ball tray 6, an opening 67 is formed on the front side of the game assisting board 20 that opens obliquely downward to the left. .

遊技補助盤20に取り付けられた補助盤カバー31の背後では、発射レール22と外レール12との間が所定間隔隔てられて上方に開くファール球回収口32が形成され、その下側にファール球回収口32に落入したファール球を流下させるファール球回収通路33が形成されている(図14を参照)。また上球皿連絡ダクト65の下側ではカバー面が前方に膨出されて上方に開口する受け皿部35が形成され、その底壁が外レール部21aの下方に延びて受け皿部35に受容した遊技球を流下させる下球皿通出通路36が形成されている。   In the back of the auxiliary board cover 31 attached to the game auxiliary board 20, a foul ball collection port 32 is formed which is opened at a predetermined distance between the firing rail 22 and the outer rail 12, and a foul ball is formed below the foul ball collection port 32. A foul ball collection passage 33 is formed through which the foul ball dropped into the collection port 32 flows (see FIG. 14). Further, a cover surface bulges forward to form a tray portion 35 that opens upward on the lower side of the upper ball tray communication duct 65, and a bottom wall thereof extends below the outer rail portion 21 a and is received by the tray portion 35. A lower ball tray outlet passage 36 is formed through which the game balls flow down.

ファール球回収通路33と下球皿通出通路36とは遊技補助盤の中央下部で合流し、上面及び前面が開放された箱状の下球皿連絡バケット37を介して下球皿7に繋がっている。また外レール部21aの下側には、補助盤カバー31の前方壁面から後方に突出して放物面状の整流壁38が形成されており、下球皿通出通路36を流下する遊技球が滑らかに下球皿連絡バケット37に導かれるようになっている。なお下球皿通出通路36の上下に延びる側壁部には、この球通路が遊技球で満たされたときに、その状態を検出する球払出通路充満検出器39が設けられている。   The foul ball collection passage 33 and the lower ball tray outlet passage 36 merge at the lower center of the game auxiliary board, and are connected to the lower ball tray 7 through a box-shaped lower ball tray connection bucket 37 whose upper surface and front surface are open. ing. In addition, a parabolic rectifying wall 38 is formed on the lower side of the outer rail portion 21a so as to protrude rearward from the front wall surface of the auxiliary board cover 31, and a game ball flowing down the lower ball tray outlet passage 36 is formed. It is smoothly guided to the lower ball tray contact bucket 37. A side wall portion extending vertically from the lower ball tray outlet passage 36 is provided with a ball discharge passage full detector 39 for detecting the state when the ball passage is filled with a game ball.

このため、上部裏機構盤の第1球出口46bから賞球連絡通路26の後端部に流入した遊技球は、通常では、誘導壁26r及び誘導通路部26aの左右の通路壁にガイドされて左右側壁の延長線の範囲内で賞球連絡通路26を前方に流下し、上球皿連絡ダクト65内の上球皿通出通路66を通って上球皿6の球皿部64に導かれる。しかし例えば上球皿通出通路66が開口部67の付近まで遊技球で満たされた状態で、さらに第1球出口46bから賞球連絡通路26に遊技球が流入したような場合には、流入した遊技球が開口部67の付近に位置する遊技球に弾かれて開口部67から下方の球受け皿35に転落し、下球皿通出通路36を転動流下して下球皿連絡バケット37に流入し下球皿7の球皿部に導かれる。   For this reason, the game ball that has flowed into the rear end portion of the winning ball communication passage 26 from the first ball outlet 46b of the upper back mechanism board is normally guided by the left and right passage walls of the guide wall 26r and the guide passage portion 26a. The prize ball connecting passage 26 flows forward within the extension line of the left and right side walls, and is guided to the ball tray portion 64 of the upper ball tray 6 through the upper ball tray outlet passage 66 in the upper ball tray connecting duct 65. . However, for example, when the upper ball tray passage 66 is filled with game balls up to the vicinity of the opening 67 and the game balls flow into the prize ball communication passage 26 from the first ball outlet 46b, the inflow The played game ball is bounced by the game ball located in the vicinity of the opening 67 and falls from the opening 67 to the lower ball receiving tray 35, and rolls down the lower ball tray outlet passage 36 to lower ball tray connecting bucket 37. And is guided to the ball tray portion of the lower ball tray 7.

すなわち、上下の裏機構盤40,50及び上球皿6が前枠2に閉止保持され、遊技に供される遊技状態では、上部裏機構盤40の第1球出口46bが賞球連絡バケット26の直上部に配設されて、球払出下降通路46〜賞球連絡通路26を介して上球皿6または下球皿7の球皿部に繋がる球払出通路L6が形成され、上部裏機構盤40の第2球出口47bが賞球連絡バケット25の側部上方に配設されて、球抜き下降通路47〜遊技済み球排出通路57を介して球排出口58に繋がる球排出通路L7が形成される。   That is, in the gaming state in which the upper and lower back mechanism boards 40 and 50 and the upper ball tray 6 are held closed by the front frame 2 and used for gaming, the first ball outlet 46b of the upper back mechanism board 40 is connected to the winning ball contact bucket 26. , A ball payout passage L6 that is connected to the ball tray portion of the upper ball tray 6 or the lower ball tray 7 through the ball payout lowering passage 46 to the prize ball communication passage 26 is formed. The second ball outlet 47b of 40 is disposed above the side portion of the winning ball communication bucket 25, and a ball discharge passage L7 is formed which is connected to the ball discharge port 58 via the ball removal descending passage 47 to the game-completed ball discharge passage 57. Is done.

さらに球払出通路L6は、賞球連絡通路26〜上球皿通出通路66〜上球皿6の球皿部64に繋がる上球皿払出通路L66と、賞球連絡通路26〜開口部67〜下球皿通出通路36〜下球皿7の球皿部に繋がる下球皿払出通路L67とからなり、上球皿6への遊技球の貯留状態に応じて流下通路及び配分が変化する。   Furthermore, the ball payout passage L6 includes an award ball communication passage 26, an upper ball tray discharge passage 66, an upper ball tray payout passage L66 connected to the ball plate portion 64 of the upper ball tray 6, and a prize ball communication passage 26 through an opening 67. The lower ball tray discharge passage 36 to the lower ball tray discharge passage L67 connected to the ball tray portion of the lower ball tray 7 and the flow down passage and distribution change according to the storage state of the game balls in the upper ball tray 6.

そこで、本構成のパチンコ機PMにおける遊技球の流れ(各球通路の作用)について以下説明する。パチンコ機PMは、図1に示すように上球皿6及びガラス扉5が閉止施錠された状態で遊技に供され、遊技者が上球皿6の球皿部64に遊技球を貯留させて発射ハンドル8の操作レバーを回動操作することにより開始される。操作レバーが回動操作されると、球皿部64に貯留された遊技球が球送りカセット69によって1球ずつ発射レール22に送り出され、遊技球発射装置21のハンマーにより打ち出される。   Therefore, the flow of game balls (action of each ball passage) in the pachinko machine PM having this configuration will be described below. As shown in FIG. 1, the pachinko machine PM is provided to the game with the upper ball tray 6 and the glass door 5 closed and locked, and the player stores the game ball in the ball tray portion 64 of the upper ball tray 6. The operation is started by rotating the operation lever of the firing handle 8. When the operation lever is turned, the game balls stored in the ball tray portion 64 are sent one by one to the launch rail 22 by the ball feed cassette 69 and are launched by the hammer of the game ball launcher 21.

ハンマーに打ち出された遊技球のうち、遊技領域PAに到達できずに外レール12に沿って戻ってきた遊技球は、ファール球回収口32に落入してファール球回収通路33を通り下球皿連絡バケット37を介して下球皿7に回収される。   Of the game balls launched by the hammer, the game balls that have returned along the outer rail 12 without reaching the game area PA fall into the foul ball collection port 32, pass through the foul ball collection passage 33, and fall below the ball. It is collected in the lower ball tray 7 via the dish connection bucket 37.

ハンマーに打ち出された遊技球のうち、遊技領域PAに到達した遊技球は、遊技領域内に打ち込まれた多数本の遊技釘や風車に弾かれながら遊技領域PAを転動落下し、落下過程で入賞装置に落入して化粧板11の裏面側に導かれ、あるいは入賞装置に落入することなく落下してアウト口18から化粧板11の裏面側に導かれ、ともに下部裏機構盤50の集合樋56に受け止められて集合され、遊技済み球排出通路57を通って下端の球排出口58から遊技施設の球回収装置に排出される。   Of the game balls launched by the hammer, the game balls that have reached the game area PA roll and fall in the game area PA while being hit by a large number of game nails and windmills that are driven into the game area. The player enters the winning device and is guided to the back side of the decorative plate 11 or falls without entering the winning device and is guided to the back side of the decorative plate 11 from the out port 18. The balls are received and gathered by the gathering basket 56 and are discharged from the ball discharge port 58 at the lower end through the game-completed ball discharge passage 57 to the ball collection device of the game facility.

遊技球が入賞装置に落入すると、各入賞装置に設けられた入賞球検出器から入賞検出信号が出力され、球払出制御基板82は入賞装置の種別に応じた払出指令信号を球払出装置42に出力し、球払出装置42は払出指令信号に応じた回転方向(正転方向)及び回転角度分だけ球払出モータを回転作動させて、所定数量(例えば、5球,10球,13球等)の遊技球を第1払出口から球払出下降通路46に払い出す。球払出下降通路46に払い出された遊技球は、この球通路下端の第1球出口46bから直下に位置する賞球連絡通路26の誘導通路部26aに流入する。   When the game ball falls into the winning device, a winning detection signal is output from a winning ball detector provided in each winning device, and the ball payout control board 82 outputs a payout command signal according to the type of the winning device. The ball payout device 42 rotates the ball payout motor by the rotation direction (forward rotation direction) and the rotation angle according to the payout command signal, and a predetermined quantity (for example, 5 balls, 10 balls, 13 balls, etc.) ) From the first payout outlet to the ball payout descending passage 46. The game ball paid out to the ball paying down passage 46 flows into the guide passage portion 26a of the prize ball communication passage 26 located directly below the first ball outlet 46b at the lower end of the ball passage.

ここで、誘導通路部26aは一定の通路幅で前方に下傾して形成され、第1球出口46bはこの誘導通路部26aの後端に形成された誘導壁26rの直上に位置して配設されている。このため、誘導通路部26aの後端部に流入した遊技球は、上球皿通出通路66が開口部67近傍まで遊技球で充満されるようになるまでは、誘導通路部26aの左右の通路壁にガイドされて左右側壁の延長線の範囲内で賞球連絡通路26を前方に流下し、上球皿連絡ダクト65内の上球皿通出通路66を通って上球皿6の球皿部64に導かれる。すなわち上球皿6が遊技球で充満される以前では、球払出装置42から払い出された遊技球が、球払出下降通路46〜賞球連絡通路26〜上球皿通出通路66〜上球皿6の球皿部に至る上球皿払出通路L66を通って上球皿6に導かれ、開口部67から下球皿通出通路36に転入して下球皿7の球皿部に至る下球皿払出通路L67を通って下球皿7に導かれる遊技球はほとんど生じない。   Here, the guide passage portion 26a is formed with a constant passage width and tilted forward, and the first ball outlet 46b is disposed directly above the guide wall 26r formed at the rear end of the guide passage portion 26a. It is installed. For this reason, the game balls that have flowed into the rear end portion of the guide passage portion 26a are left and right of the guide passage portion 26a until the upper ball tray passage passage 66 is filled with the game balls up to the vicinity of the opening 67. Guided by the passage wall, the prize ball communication passage 26 flows forward within the extension line of the left and right side walls, passes through the upper ball tray outlet passage 66 in the upper ball tray connection duct 65, and the ball of the upper ball tray 6. Guided to the pan 64. That is, before the upper ball tray 6 is filled with the game balls, the game balls paid out from the ball payout device 42 are moved from the ball payout descending passage 46 to the prize ball communication passage 26 to the upper ball tray outlet passage 66 to the upper ball. The ball is guided to the upper ball tray 6 through the upper ball tray discharge passage L66 leading to the ball tray portion of the tray 6, and is transferred from the opening 67 to the lower ball tray outlet passage 36 to reach the ball tray portion of the lower ball tray 7. Little game balls are guided to the lower ball tray 7 through the lower ball tray payout passage L67.

遊技の展開に伴い、遊技球発射装置21から遊技領域PAに発射される遊技球の数量よりも入賞に対して払い出される遊技球の数量の方が多い状態が続くと、上球皿6の貯留球数が徐々に増加し、これに伴って球皿部64に貯留される貯留球が傾斜上方に遡って球皿部64を覆い、さらに球皿部64と段差がある上球皿通出通路66の出口前方で複数段に積み上がって球皿部全体が遊技球で満たされた状態になってくる。   As the game progresses, if the number of game balls to be paid out for winning is larger than the number of game balls launched from the game ball launcher 21 to the game area PA, the upper ball tray 6 is stored. The number of balls gradually increases, and accordingly, the stored balls stored in the ball tray part 64 go up the slope to cover the ball dish part 64, and further, there is a step difference from the ball dish part 64. At the front of the exit 66, the balls are stacked in a plurality of stages, and the entire ball tray is filled with game balls.

そして上球皿通出通路66の入り口部が遊技球で満たされ、開口部67の近傍まで遊技球が停留するようになると、上球皿連絡通路66に新たに流入する遊技球が既に停留していた遊技球に弾かれて左方向に誘導され、あるいは開口部67の近傍に停留していた遊技球が新たに上球皿連絡通路66に流入した遊技球に押圧されて左方向に押し出され、開口部67から受け皿部35に転入するようになる。受け皿部35に転入した遊技球は、下球皿通出通路36を滑らかに転動流下し、下球皿連絡バケット37を介して下球皿7に至る下球皿払出通路L67を通って下球皿7に導かれる。   When the entrance of the upper ball tray passage 66 is filled with game balls and the game ball stops near the opening 67, the game ball newly flowing into the upper ball tray connection passage 66 has already stopped. The game ball that has been bounced by the game ball that has been guided and guided to the left or stopped in the vicinity of the opening 67 is pushed by the game ball that has newly flown into the upper ball tray communication passage 66 and pushed leftward. Then, it comes into the tray part 35 through the opening 67. The game ball that has been transferred to the tray part 35 smoothly rolls down the lower ball tray outlet passage 36 and passes through the lower ball tray discharge passage L67 that reaches the lower ball tray 7 via the lower ball tray connecting bucket 37. Guided to the ball tray 7.

ここで、上球皿通出通路66に遊技球が貯留され始めた時期に、開口部67から受け皿部35に転落する遊技球は、既に上球皿通出通路66に停留していた遊技球(便宜的に停留球という)と接触して開口部67の方向に弾かれた遊技球と、後方に停留した遊技球に押圧されて開口部67の方向に押し出された遊技球とがある。   Here, when the game ball starts to be stored in the upper ball tray passage 66, the game ball that falls from the opening 67 to the tray portion 35 has already stopped in the upper ball tray passage 66. There are a game ball that is played in the direction of the opening 67 in contact with the ball (for convenience) and a game ball that is pushed in the direction of the opening 67 by being pressed by the game ball that is parked rearward.

このうち、前者については、停留球に接触して弾かれた遊技球の転動方向がほぼ左側方に位置する開口部67に向かう遊技球に限られ、誘導通路部26bの作用によりまっすぐ前方に向けて流入してきた遊技球を、大きな反射角で反射するような場合に限られる。また、後者については、停留球の後方に繋がる遊技球から当該停留球に作用する押圧力のベクトルと、停留球よりも前方に位置する遊技球から当該停留球に作用する押圧力のベクトルとを合成した合力が左方向(開口部67の開口前方)に向かうものに限られる。すなわち、停留球に作用する合力は、当該停留球とその前後に位置する遊技球との球面同士の当接角度位置関係による押圧力の作用方向及び押圧力の大きさにより定まり、その合力が左方向となる停留球だけが押し出されて開口部67から受け皿部35に転入する。   Among these, for the former, the rolling direction of the game ball bounced in contact with the stationary ball is limited to the game ball heading toward the opening 67 located substantially on the left side, and straight forward by the action of the guide passage portion 26b. This is limited to the case where the game ball flowing in is reflected at a large reflection angle. For the latter, a vector of pressing force acting on the stationary ball from the game ball connected to the rear of the stationary ball and a vector of pressing force acting on the stationary ball from the gaming ball located in front of the stationary ball. The resultant resultant force is limited to the direction toward the left (front of the opening of the opening 67). That is, the resultant force acting on the stationary ball is determined by the acting direction of the pressing force and the magnitude of the pressing force due to the contact angle positional relationship between the spherical surfaces of the stationary ball and the game ball positioned before and after the stationary ball, and the resultant force is Only the stationary ball in the direction is pushed out and transferred into the tray portion 35 from the opening 67.

従って、上球皿通出通路66に遊技球が貯留され始めた時点では、開口部67から受け皿部35に転入する遊技球は上記条件を満たすわずかな数量となり、球払出装置42から遊技球が払い出されるごとに少数ずつ開口部67から受け皿部35に転落し、下球皿払出通路L67を流下して下球皿7に導出される。これにより、遊技者は球払出通路L6が充満される以前の早期の段階で、上球皿払出通路L66が徐々に満たされつつあることを認識することができ、遊技球が少しずつ下球皿7に流下し始めた時点で、遊技施設の呼び出しランプ等を用いて遊技施設の係員を呼び、球箱を受け取って球抜き作業の準備を行うことができる。   Therefore, when the game balls start to be stored in the upper ball tray outlet passage 66, the number of game balls transferred into the tray portion 35 from the opening 67 becomes a small quantity satisfying the above condition, and the game balls are transferred from the ball dispensing device 42. Each time it is paid out, a small number falls from the opening 67 to the tray part 35, flows down the lower ball dish discharge passage L 67, and is led out to the lower ball dish 7. Thereby, the player can recognize that the upper ball tray payout passage L66 is gradually filled at an early stage before the ball payout passage L6 is filled, and the game balls are gradually added to the lower ball tray. When the player starts to flow down to 7, the game facility staff can be called using a game facility call lamp or the like to receive the ball box and prepare for the ball removal work.

このように払い出された遊技球が少しずつ下球皿7に流下する予告報知の状態で、さらに遊技球が次々払い出されると、払い出された遊技球が上球皿通出通路66の上流まで停留するようになり、とくに開口部67の存在しない右側では遊技球が盛り上がった状態で充満されるようになり、一部は賞球連絡バケット25側の賞球連絡通路66にも停留するようになる。   When the game balls that have been paid out in this manner are informed in advance to flow down to the lower ball tray 7 little by little, if the game balls are further paid out one after another, the game balls that have been paid out will be upstream of the upper ball tray outlet passage 66. In particular, the game ball is filled in a raised state on the right side where the opening 67 does not exist, and a part of the game ball also stops in the prize ball communication passage 66 on the prize ball connection bucket 25 side. become.

そして上記のように、上球皿通出通路66が上流端まで遊技球で充満され、さらに賞球連絡通路66にも遊技球が停留するようになると、通路内に停留する遊技球数の増加に伴って開口部67近傍の停留球に作用する押圧力が増大し、これによって開口部67に押し出される遊技球が増加する。また誘導通路部26aの効果により賞球連絡通路26をほぼまっすぐに前方に流下して上球皿通出通路66に流入していた遊技球が、通路前方に停留した遊技球に弾かれて拡大通路部26bを流下し、あるいは停留球が存在しない拡大通路部26bに押し出されて通路拡大部26bを流下し、開口部67から受け皿部35に転入するようになる。   As described above, when the upper ball tray passage 66 is filled with game balls up to the upstream end, and the game balls are also stopped in the prize ball connection passage 66, the number of game balls stopped in the passage is increased. Along with this, the pressing force acting on the stationary ball in the vicinity of the opening 67 increases, whereby the number of game balls pushed out to the opening 67 increases. Also, the game balls that have flowed almost straight down the prize ball communication passage 26 and flowed into the upper ball tray passage 66 due to the effect of the guide passage portion 26a are bounced and expanded by the game balls stopped in front of the passage. It flows down the passage portion 26 b or is pushed out by the enlarged passage portion 26 b where no stationary ball is present and flows down the passage enlarged portion 26 b, and then moves into the tray portion 35 from the opening 67.

このため、上球皿通出通路66が遊技球で充満され賞球連絡通路66にも遊技球が停留するようになると、開口部67から受け皿部35に転入する遊技球の数量が増加し、球払出装置42から遊技球が払い出されるごとに、あるいは遊技球の発射により球皿部64の貯留球が消費されて上球皿通出通路66が漸次流下し停留球への押圧力が変動するごとに、開口部67から受け皿部35に転入して下球皿払出通路L67を流下し下球皿7に導出されるようになる。   For this reason, when the upper ball tray passage 66 is filled with game balls and the game balls stop in the prize ball communication passage 66, the number of game balls transferred from the opening 67 to the tray portion 35 increases. Each time a game ball is paid out from the ball payout device 42 or when the game ball is fired, the stored ball in the ball tray portion 64 is consumed, the upper ball tray outlet passage 66 gradually flows down, and the pressing force to the stationary ball fluctuates. Every time, it moves into the tray part 35 from the opening 67 and flows down through the lower ball tray discharge passage L67 to be led out to the lower ball tray 7.

この状態では、新たに払い出された遊技球の多くは下球皿払出通路L67を通って下球皿7に払い出される。すなわち、上球皿の球皿部64が充満されて以降上球皿通出通路66が充満されるまでは、逐次少数の遊技球が下球皿7に導出される一方、上球皿通出通路66が充満されて以降では、多数の遊技球が下球皿7に払い出されるようになり、これにより遊技者は上球皿球払出通路L66が充満状態に近いことを的確に認識することができる。そこで、遊技者は予告報知の段階で準備した球箱を下球皿7の球抜き口の下側に配設し、下球皿7への払出状況や貯留状態を見ながら下部球抜き機構の球抜きレバーを操作して球抜き作業を行うことができる。   In this state, most of the newly paid game balls are paid out to the lower ball tray 7 through the lower ball tray payout passage L67. That is, a small number of game balls are sequentially led out to the lower ball tray 7 until the upper ball tray outlet passage 66 is filled after the ball tray portion 64 of the upper ball tray is filled. After the passage 66 is filled, a large number of game balls are paid out to the lower ball tray 7, and thereby the player can accurately recognize that the upper ball tray ball discharge passage L66 is almost full. it can. Therefore, the player arranges the ball box prepared at the notice notification stage below the ball outlet of the lower ball tray 7, and observes the state of paying out to the lower ball tray 7 and the storage state of the lower ball removing mechanism. The ball removal operation can be performed by operating the ball removal lever.

さて、以上では通常の遊技状態における遊技球の流れについて説明したが、次に球抜き操作が行われたときの遊技球の流れについて説明する。球抜き操作は、いわゆる打ち止めと称される定量制限に達して貯留タンク部41aに残留した遊技球を遊技施設の回収装置に排出させるときや、営業終了後に貯留タンク部41aに残留した遊技球を全量排出させるときなどに行われ、例えばパチンコ機PMの前面に設けられた球抜き操作孔(不図示)にハートキーと称される球抜き操作用のジグを挿入し、機体内部の球抜きスイッチを押圧操作することにより行われる。   Now, the flow of the game ball in the normal game state has been described above. Next, the flow of the game ball when the ball removal operation is performed will be described. The ball removal operation is performed when the game ball remaining in the storage tank unit 41a is discharged to the collection device of the game facility after reaching a quantitative limit called so-called “stopping”, or when the game ball remaining in the storage tank unit 41a after the business is over. For example, a ball removal switch called a heart key is inserted into a ball removal operation hole (not shown) provided on the front surface of the pachinko machine PM, and the ball removal switch inside the machine body. It is performed by pressing.

球抜きスイッチが押圧操作されると、球抜きスイッチから球払出制御基板82に球抜き操作信号が入力され、球払出制御基板82は球抜き操作信号に基づいて球抜き指令信号を球払出装置42に出力する。球払出装置42は球抜き指令信号に応じた回転方向(逆転方向)及び回転角度分だけ球払出モータを回転作動させて、設定条件を満たす数量の遊技球を第2払出口から球抜き下降通路47に排出させる。具体的には、予め設定された所定時間球払出モータを逆転作動させ、あるいは球貯留アッセンブリ40Bに内蔵された球有無検出器で球貯留部の遊技球が全量排出されたことが検出されるまで球払出モータを逆転作動させ、貯留タンク部41aに貯留された遊技球を球払出装置42の第2球払出口から球抜き下降通路47に排出させる。   When the ball removal switch is pressed, a ball removal operation signal is input from the ball removal switch to the ball dispensing control board 82. The ball dispensing control board 82 sends a ball removal command signal to the ball dispensing device 42 based on the ball removal operation signal. Output to. The ball payout device 42 rotates the ball payout motor by the rotation direction (reverse direction) and the rotation angle in accordance with the ball discharge command signal, and the number of game balls satisfying the set condition are discharged from the second payout opening to the ball discharge downward passage. 47 to discharge. Specifically, the ball payout motor is reversely operated for a predetermined time set in advance, or until it is detected by the ball presence / absence detector built in the ball storage assembly 40B that all the game balls in the ball storage unit have been discharged. The ball payout motor is operated in reverse, and the game balls stored in the storage tank portion 41a are discharged from the second ball payout outlet of the ball payout device 42 to the ball removal descending passage 47.

球抜き出下降通路47に排出された遊技球は、この球通路下端の第2球出口47bから賞球連絡バケット25の右側方を通って落下し、集合樋の右側壁56Rに受け止められて遊技済み球排出通路57を流下し、下端の球排出口58から遊技施設側の球回収装置に排出される。すなわち、球抜き操作が行われたときには、球払い出しモータが払い出し作動と反対方向に回転駆動されて、球払出装置42の第2払出口から遊技球が排出され、球抜き下降通路47〜遊技済み球排出通路57〜球排出口58に至る球排出通路L7を通って遊技施設側の球回収装置に導かれる。   The game balls discharged to the ball withdrawal / lowering passage 47 fall from the second ball outlet 47b at the lower end of the ball passage through the right side of the prize ball connection bucket 25, and are received by the right side wall 56R of the collective basket. It flows down the used ball discharge passage 57 and is discharged from the ball discharge port 58 at the lower end to the ball collection device on the game facility side. That is, when the ball removal operation is performed, the ball payout motor is driven to rotate in the direction opposite to the payout operation, and the game ball is discharged from the second payout outlet of the ball payout device 42, and the ball removal descending passage 47 to the game completed. Through the ball discharge passage L7 extending from the ball discharge passage 57 to the ball discharge port 58, the ball is guided to the ball collection device on the game facility side.

以上説明したように、本構成の球通路構造では、上部裏機構盤40の上部に設けた球払出装置42の下側に、球払出通路L6の賞球下降通路46と、球排出通路L7の球抜き下降通路47とを前後に重ねて設け、かつこれらの球通路を前後方向に屈曲するS字状の中央通路壁44cを隔てて隣接して形成している。このため、賞球下降通路46及び球抜き下降通路47の両通路について静粛かつ滑らかな払い出し及び球抜きを確保しながら、これらの球通路が形成された上部裏機構盤40の左右方向の幅を減少させて窓口開口を拡大することができ、これにより遊技盤から後方に突設可能な領域を拡大してゲージ設定の自由度を拡大することができる。   As described above, in the ball passage structure of this configuration, the award ball lowering passage 46 of the ball payout passage L6 and the ball discharge passage L7 are provided below the ball payout device 42 provided in the upper portion of the upper back mechanism board 40. The ball removal descending passage 47 is provided so as to overlap in the front-rear direction, and these ball passages are formed adjacent to each other with an S-shaped central passage wall 44c bent in the front-rear direction. For this reason, the width of the upper back mechanism board 40 formed with these ball passages in the left-right direction is secured while ensuring quiet and smooth payout and ball removal for both the award ball lowering passage 46 and the ball removal lowering passage 47. The window opening can be enlarged by reducing the area, and thereby the area that can be projected rearward from the game board can be expanded to increase the degree of freedom in setting the gauge.

また、本構成の球通路構造では、前枠2の後面側に開閉可能に取り付けられた下部ベース51の閉鎖姿勢において、下部ベース51の前面側に左右の側壁56L,56Rを有する遊技済み球排出通路57が形成され、これら側壁の間に突出する賞球連絡バケット25により球払出下降通路46と上球皿通出通路66との間を繋ぐ賞球連絡通路26が遊技済み排出通路57の通路内に配設されるように構成している。このため、裏機構盤の通路構成を簡明化できるとともに、遊技済み球排出通路57に球詰まりが生じた場合でも、下部ベース51の後面側に取り付けられた回路基板や電気部品等を取り外すことなく下部ベース51(裏機構盤50)を後方に開放して球抜き処理することができる。   Further, in the ball path structure of this configuration, in the closed posture of the lower base 51 attached to the rear side of the front frame 2 so as to be openable and closable, the game-completed ball discharge having left and right side walls 56L and 56R on the front side of the lower base 51 A path 57 is formed, and a prize ball communication path 26 that connects between the ball paying-down path 46 and the upper ball tray outlet path 66 by the prize ball connection bucket 25 protruding between the side walls is a path of the game-completed discharge path 57. It is comprised so that it may be arrange | positioned in. For this reason, the passage structure of the back mechanism board can be simplified, and even when a ball clogging occurs in the game-completed ball discharge passage 57, without removing a circuit board or an electrical component attached to the rear side of the lower base 51. The lower base 51 (back mechanism panel 50) can be opened rearward for ball removal.

また、本構成の球通路構造では、球払出通路L6の途上における賞球連絡通路26を、一定の通路幅で前方に延びる誘導通路部26aと、通路幅が前方に向けて拡大する拡大通路部26bとから構成するとともに、賞球連絡通路26の前方に誘導通路部26aの延長線よりも外側に位置して開口部67を設け、この開口部67と下球皿7との間を繋いで下球皿通出通路36を形成している。このため、上球皿6が充満状態のときに遊技球を下球皿7に導く下球皿払出通路を裏機構盤BSPに形成する必要がなく、従来裏機構盤に設けられていた下球皿払出通路を削除して裏機構盤の通路構成を簡明化できることに加えて、球払出通路L6に球詰まりが生じた場合でも前枠2や裏機構盤40,50を開放することなく、上球皿6を開放することで前枠前面側で球詰まり処理を行うことが可能となり、球詰まり処理の作業性を大幅に改善することができる。   Further, in the ball passage structure of this configuration, the winning ball communication passage 26 in the middle of the ball payout passage L6 has a guide passage portion 26a extending forward with a constant passage width, and an enlarged passage portion in which the passage width expands forward. 26b, and an opening 67 is provided in front of the prize ball communication passage 26 outside the extension line of the guide passage portion 26a. The opening 67 and the lower ball tray 7 are connected to each other. A lower ball tray outlet passage 36 is formed. For this reason, it is not necessary to form a lower ball tray payout passage for guiding the game ball to the lower ball tray 7 when the upper ball tray 6 is full in the back mechanism board BSP, and the lower ball provided in the conventional back mechanism board has been provided. In addition to simplifying the passage structure of the back mechanism board by deleting the dish delivery path, the top frame 2 and the back mechanism boards 40 and 50 can be opened without opening the front frame 2 and the back mechanism boards 40 and 50 even when a ball clogging occurs in the ball delivery path L6. By opening the ball tray 6, it becomes possible to perform a ball clogging process on the front side of the front frame, and the workability of the ball clogging process can be greatly improved.

さらに、上球皿6の球皿部が遊技球で充満される以前においては、賞球連絡通路26に流入した遊技球が誘導通路部26aに誘導されて通路側壁の延長線内で前方に流下し、上球皿通出通路66を通って上球皿6の球皿部に払い出される一方、上球皿6が遊技球で充満し上球皿通出通路66を遡って貯留されるようになると、球払出装置42から払い出された遊技球が下球皿通出通路36を通って少しずつ下球皿7に流下し、かつその流下量が充満状態に応じて変化して、上球皿払出通路が満たされつつあることを予告報知する。このため、遊技者は上球皿払出通路66が充満される以前に球払出通路L6が満たされつつあることを認識することができ、余裕を持って球箱を準備することができる。   Further, before the ball tray portion of the upper ball tray 6 is filled with game balls, the game balls flowing into the prize ball communication passage 26 are guided to the guide passage portion 26a and flow forward in the extension line of the passage side wall. Then, the upper ball tray 6 is paid out to the ball tray portion of the upper ball tray 6 through the upper ball tray outlet passage 66, while the upper ball tray 6 is filled with game balls and is stored retroactively through the upper ball tray outlet passage 66. Then, the game balls paid out from the ball payout device 42 flow little by little to the lower ball tray 7 through the lower ball tray outlet passage 36, and the amount of the flow changes according to the full state. A notice is given that the dish dispensing passage is being filled. Therefore, the player can recognize that the ball payout passage L6 is being filled before the upper ball tray payout passage 66 is filled, and can prepare the ball box with a margin.

従って、以上説明した本構成の球通路構造によれば、弾球遊技機の球通路構成を簡明化して生産コスト低減に寄与するとともに、球詰まり処理作業の繁雑さを解消し、かつ球払出通路が充満されるまでに余裕を持って球箱を準備可能な球通路構造を提供することができる。   Therefore, according to the ball passage structure of the present configuration described above, the ball passage configuration of the ball game machine is simplified to contribute to the reduction of production cost, the complexity of the ball clogging processing work is eliminated, and the ball payout passage is provided.
