Description

本発明は、遊技盤を着脱可能に収容保持する収容枠が設けられた前枠と、入賞状態に応じて遊技球を払い出す球払出機構及び遊技盤から排出された遊技球を機体の外部に排出する遊技済み球排出機構が設けられて前枠の後面側に取り付けられた裏機構盤とを備えた弾球遊技機の盤構造に関する。   The present invention includes a front frame provided with a storage frame for detachably storing and holding a game board, a ball payout mechanism for paying out game balls according to a winning state, and game balls discharged from the game board outside the machine body. The present invention relates to a board structure of a ball game machine including a back mechanism board provided with a discharged ball discharging mechanism for discharging and attached to the rear side of a front frame.

上記のような前枠及び裏機構盤を備えた弾球遊技機として、例えばパチンコ機や雀球遊技機、アレンジボール機などが広く知られている。この種の遊技機の代表例とされるパチンコ機では、ベニヤとも称される化粧板の前面に、多数本の遊技釘とともに風車、固定入賞具、図柄表示装置、種々の可動入賞装置や可動装飾装置などの遊技部品が取り付けられた遊技盤が用いられ、この遊技盤が開閉搭載枠たる前枠に取り付けられ、その後方に裏機構盤と称される機構セット盤が取り付けられて一体のパチンコ機が形成される。   As a ball game machine provided with the front frame and the back mechanism board as described above, for example, a pachinko machine, a sparrow ball game machine, an arrangement ball machine, and the like are widely known. In a pachinko machine that is a typical example of this type of gaming machine, a windmill, a fixed prize device, a symbol display device, various movable prize winning devices and movable decorations are mounted on the front surface of a decorative board, also called a veneer, together with a number of game nails. A game board to which game parts such as devices are attached is used, this game board is attached to a front frame which is an open / close mounting frame, and a mechanism set board called a back mechanism board is attached to the back of the game board, and an integrated pachinko machine Is formed.

パチンコ機では、機体のベースとなる前枠や裏機構盤が一定期間一定の仕様で設定される一方、製造工場における生産機種の変更や、遊技施設におけるいわゆる盤面換え等を容易に行い得るように、遊技盤を着脱可能に収容する収容枠が前枠の前面側または後面側に形成され、この収容枠に機種ごとに異なるゲージ設定で形成された遊技盤を収容させ係止保持させることで、生産機種の変更や盤面換えを容易に行えるように構成されている。   In pachinko machines, the front frame and the back mechanism board, which are the bases of the machine body, are set with constant specifications for a certain period of time, while changing the production model at the manufacturing plant and so-called board change at the amusement facility can be performed easily. The storage frame for detachably storing the game board is formed on the front side or the rear side of the front frame, and by holding and holding the game board formed with different gauge settings for each model in this storage frame, It is configured to make it easy to change production models and change the panel.

一方、遊技盤の後方に取り付けられる裏機構盤は、遊技盤における入賞状態に応じて遊技球を払い出す球払出機構、遊技盤から排出された遊技球を機体の外部に排出する遊技済み球排出機構が設けられるとともに、パチンコ機の作動を制御する電源基板や球払出制御基板、主制御基板などの各種回路基板が、不正改造されないように基板ケースに収められた状態で着脱可能に取り付けられる。裏機構盤には、上記球払出機構等を構成する球払出通路や溢れ球通路、球抜き通路、遊技済み球排出通路など、遊技球の流下経路に応じた複数の球通路を形成する必要があることから、前後を仕切る仕切壁を挟んで球通路が交差する前後2層の通路構成とされ、かつ遊技盤の後方に位置して前枠の後面側ほぼ全体を覆う大型の枠状に一体成型されていた。   On the other hand, the back mechanism board attached to the back of the game board is a ball payout mechanism that pays out game balls according to the winning state of the game board, and a game-completed ball discharge that discharges game balls discharged from the game board to the outside of the machine body. A mechanism is provided, and various circuit boards such as a power supply board, a ball payout control board, and a main control board that control the operation of the pachinko machine are detachably attached in a state of being housed in a board case so as not to be tampered with. In the back mechanism board, it is necessary to form a plurality of ball passages corresponding to the flow-down path of the game balls, such as a ball payout passage, an overflow ball passage, a ball removal passage, and a game-completed ball discharge passage constituting the ball payout mechanism and the like. Therefore, it is a two-layered front and rear passage structure where the ball passage intersects across the front and rear partition walls, and is integrated in a large frame shape that is located behind the game board and covers almost the entire rear side of the front frame It was molded.

このため、例えば収容枠を前枠の後面側に有し、遊技盤を前枠の後方から着脱する形態(遊技盤後方脱着形態)のパチンコ機では、裏機構盤が前枠の後面側にヒンジ機構を介して横開き開閉可能に取り付けられており、遊技盤を着脱交換する場合や、裏機構盤前面側の球通路(例えば球抜き通路や遊技済み球排出通路)の清掃作業を行う場合などには、前枠を外枠の前方に開放し裏機構盤を前枠の後方に横開き開放した状態で上記各作業を行えるように構成されていた(例えば特許文献1を参照)。また収容枠を前枠の前面側に有し、ガラス扉を開放した状態で遊技盤を前枠の前方から着脱する形態(遊技盤前方脱着形態)のパチンコ機では、裏機構盤が前枠の前面側に回動レバー等により着脱可能に取り付けられており、裏機構盤前面側の球通路の清掃作業を行う場合などには、前枠を外枠の前方に開放し裏機構盤全体を前枠から取り外して作業を行えるように構成されていた(例えば特許文献2を参照)。   For this reason, for example, in a pachinko machine having a housing frame on the rear side of the front frame and the game board being attached to and detached from the rear of the front frame (game board rear detaching form), the back mechanism board is hinged to the rear side of the front frame. It is attached through a mechanism so that it can be opened and closed sideways, and when the game board is removed or replaced, or when the ball path on the front side of the back mechanism panel (for example, a ball removal path or a game ball discharge path) is cleaned. Is configured such that each of the above operations can be performed with the front frame opened to the front of the outer frame and the back mechanism panel opened laterally to the rear of the front frame (see, for example, Patent Document 1). In addition, in a pachinko machine having a storage frame on the front side of the front frame and the game board being detached from the front of the front frame with the glass door open (game board front attachment / detachment form), the back mechanism board is the front frame When the ball path on the front side of the back mechanism panel is cleaned, the front frame is opened to the front of the outer frame and the entire back mechanism panel is moved forward. It was comprised so that it could remove and work from a frame (for example, refer to patent documents 2).

特開2003−144713号公報(第3〜5頁、第2〜6図)Japanese Patent Laid-Open No. 2003-144713 (pages 3 to 5 and FIGS. 2 to 6) 特開2004−194881号公報(第3〜4頁、第2〜5図)Japanese Patent Application Laid-Open No. 2004-194881 (pages 3-4, FIGS. 2-5)

しかしながら、従来の裏機構盤は、その上下左右方向の寸法が、遊技盤の脱着形態によらず何れも前枠とほぼ同様の大きさを有して一体に形成されており、裏機構盤を開閉しまたは着脱するには、この比較的大型の裏機構盤全体を開放または着脱する必要があった。このため、例えば遊技盤後方脱着形態のパチンコ機において遊技盤の着脱交換を行う場合や、大入賞口内部(裏側)の球詰まり処理など遊技盤裏面側の保守作業を行う場合、あるいは裏機構盤前面側の一部通路の保守作業を行うような場合に、裏機構盤全体を開放して作業を行う必要があり、裏機構盤を開放したときに遊技球がこぼれ落ちないように球抜き作業を行ったり、関連するコネクタケーブルの嵌脱作業を行ったりする付帯作業を含めると結構な作業工数がかかるという問題があった。   However, the conventional back mechanism board is integrally formed so that the dimensions in the vertical and horizontal directions have almost the same size as the front frame regardless of the attachment / detachment mode of the game board. In order to open / close or attach / detach, it was necessary to open or attach / detach the relatively large back mechanism panel. For this reason, for example, when a game board is attached / detached and replaced in a pachinko machine that is attached / detached at the rear of the game board, when maintenance work is performed on the back side of the game board such as a ball clogging process inside the prize winning opening (back side), or the back mechanism board When performing maintenance work on a part of the passage on the front side, it is necessary to open the entire back mechanism board, and work to remove the balls so that the game balls do not fall out when the back mechanism board is opened. Including incidental work such as performing or connecting / disconnecting related connector cables, there is a problem that it takes a considerable amount of work.

また裏機構盤を係止する回動レバーを解放位置にして係合を解除させ、裏機構盤を前枠後方に取り外すように構成された形態のパチンコ機では、上記問題に加えて、球貯留タンクに貯留された遊技球を全量球抜きしなければ裏機構盤を取り外すことができず、実際に行うべき作業(遊技盤の交換作業や球詰まり処理作業)よりも裏機構盤を取り外すための作業の方が工数がかかって繁雑に耐えないという問題や、遊技を中断される遊技者に多大な迷惑をかけるという問題も指摘されていた。   In addition to the above problem, the pachinko machine configured to release the engagement by turning the lever that locks the back mechanism board to the release position and remove the back mechanism board to the rear of the front frame, The back mechanism board cannot be removed unless all of the game balls stored in the tank are removed, and it is necessary to remove the back mechanism board rather than the actual work (game board replacement work or ball clogging work). It was pointed out that the work requires more man-hours and cannot withstand the complications, and that it causes great inconvenience to players who are interrupted.

本発明は上記のような事情に鑑みてなされたものであり、余計な付帯工数をかけることなく、作業目的に応じて適切かつ迅速に作業を行うことができる弾球遊技機の盤構造を提供することを目的とする。   The present invention has been made in view of the circumstances as described above, and provides a board structure for a ball game machine capable of performing work appropriately and quickly in accordance with the work purpose without incurring extra man-hours. The purpose is to do.

上記目的達成のため、本発明は、遊技球が落入可能な入賞装置を有する遊技盤を着脱可能に収容保持する収容枠が設けられた前枠と、入賞装置に遊技球が落入したときに遊技球を払い出す球払出機構及び遊技盤から排出された遊技球を機体の外部に排出する遊技済み球排出機構が設けられ前枠の後面側に取り付けられる裏機構盤とを備えた弾球遊技機に関するものである。そのうえで、本発明の盤構造では、裏機構盤を、球払出機構を有して遊技盤の後方に設けられた上部裏機構盤と、遊技済み球排出機構を有して上部裏機構盤の下側に設けられた下部裏機構盤とから構成し、遊技盤の後方に位置する上部裏機構盤を前枠の後面側に独立して開閉可能に配設し、下部裏機構盤の後面側に、弾球遊技機を作動させるための複数の回路基板を装着する基板取付部を設けるとともに、基板取付部に複数の回路基板が装着された状態で当該複数の回路基板の前方を一体的に覆う金属板を設け、金属板の面積は複数の回路基板の装着面積よりも大きく設定され、基板取付部に複数の回路基板が装着された状態で、金属板が少なくとも何れかの回路基板の前方から側方に延びて配設されるように構成し、回路基板の前方から側方に延びて配設された金属板の延出部に、アース線を嵌脱自在に接続する接続端子部と、回路基板が発生した熱を放出する放熱部と、前枠に設けられた前枠側ヒンジ部材と係合連結されて下部裏機構盤を前枠の後面側に開閉可能に支持させる下部裏機構盤ヒンジ部とを形成する。 In order to achieve the above object, the present invention provides a front frame provided with a storage frame for detachably storing and holding a game board having a winning device into which a game ball can be dropped, and a game ball dropped into the winning device. A ball ball having a ball payout mechanism for paying out game balls and a back mechanism board attached to the rear side of the front frame, provided with a game ball discharge mechanism for discharging game balls discharged from the game board to the outside of the machine body It relates to gaming machines. In addition, in the board structure of the present invention, the back mechanism board has a ball payout mechanism and an upper back mechanism board provided at the rear of the game board, and a game-completed ball discharge mechanism and under the upper back mechanism board. consist of a lower back mechanism Release provided on the side, independently of the rear side of the front frame upper back mechanism plate located behind the game board and arranged to be opened and closed, the rear surface side of the lower back mechanism Release A board mounting portion for mounting a plurality of circuit boards for operating the ball game machine is provided, and the front of the plurality of circuit boards is integrally covered with the plurality of circuit boards mounted on the board mounting portion. A metal plate is provided, the area of the metal plate is set larger than the mounting area of the plurality of circuit boards, and the plurality of circuit boards are mounted on the board mounting portion, the metal plate is at least from the front of any circuit board Configured to extend sideways, from the front side of the circuit board A connecting terminal portion for removably connecting a ground wire to an extending portion of the metal plate arranged extending in the direction, a heat radiating portion for releasing heat generated by the circuit board, and a front frame provided on the front frame A lower back mechanism board hinge portion is formed which is engaged with and connected to the side hinge member and supports the lower back mechanism board on the rear side of the front frame so as to be openable and closable .

また、上記した上部裏機構盤及び下部裏機構盤を、前枠の後面側に各々独立して開閉可能に配設する。   Further, the upper back mechanism board and the lower back mechanism board described above are disposed on the rear side of the front frame so as to be independently opened and closed.

なお、下部裏機構盤の上端面の形状及び配設位置を、遊技盤が収容枠に収容保持され下部裏機構盤が前枠に閉止された状態で、下部裏機構盤の前方に位置する遊技盤の下端面よりも下方に位置するように設定し、下部裏機構盤を前枠に閉止させた状態で遊技盤を収容枠に着脱可能に構成することが望ましい。   Note that the shape and arrangement position of the upper end surface of the lower back mechanism board is determined so that the game board is located in front of the lower back mechanism board in a state where the game board is housed and held in the housing frame and the lower back mechanism board is closed to the front frame. It is desirable to set the game board so as to be positioned below the lower end surface of the board, and to detachably attach the game board to the housing frame in a state where the lower back mechanism board is closed to the front frame.

上記盤構造では、前枠の後面側に配設される裏機構盤が、球払出機構を有する上部裏機構盤と遊技済み球排出機構を有する下部裏機構盤とから構成され、このうち遊技盤の後方に位置する上部裏機構盤が、前枠の後面側に独立して開閉可能に配設される。このため、例えば前述した遊技盤後方脱着形態のパチンコ機において、大入賞口内部の球詰まり処理を行う場合や、球払出機構の保守作業を行うような場合に、遊技盤の後方に位置する上部裏機構盤のみを開放して作業を行うことができ、下球皿の球抜き作業や下部裏機構盤側の回路基板と前枠側の回路基板とを接続するコネクタケーブルの嵌脱作業のような本来的に必要のない余計な付帯工数を削減することができる。また球払出機構を有する上部裏機構盤が開閉可能に設けられているため、球貯留タンクに貯留された遊技球を全量球抜きすることなく遊技盤の保守作業等を行うことができる。   In the above-mentioned board structure, the back mechanism board disposed on the rear side of the front frame is composed of an upper back mechanism board having a ball payout mechanism and a lower back mechanism board having a played ball discharge mechanism, and of these, the game board The upper back mechanism board located behind is disposed on the rear side of the front frame so as to be opened and closed independently. For this reason, for example, in the pachinko machine of the above-mentioned game board rear attachment / detachment form, when performing ball clogging processing inside the big prize opening, or when performing maintenance work of the ball payout mechanism, the upper part located behind the game board Only the back mechanism panel can be opened, and work can be performed, such as the ball removal work of the lower bowl and the connector cable connecting and disconnecting the circuit board on the lower back mechanism board side and the circuit board on the front frame side. It is possible to reduce unnecessary incidental man-hours that are not essentially necessary. Since the upper back mechanism board having the ball payout mechanism is provided so as to be openable and closable, maintenance work of the game board can be performed without removing all the game balls stored in the ball storage tank.

また、上部裏機構盤及び下部裏機構盤を、前枠の後面側にそれぞれ独立して開閉可能に配設する盤構造によれば、上記効果に加えて、目的とする作業の内容に応じて上下何れかの裏機構盤を単独で開放して保守作業等を行うことができるため、作業目的に応じた裏機構盤(例えば下部裏機構盤)のみを選択的に開放して作業を行うことで作業効率を向上させることができる。   Further, according to the panel structure in which the upper back mechanism panel and the lower back mechanism panel are independently opened and closed on the rear surface side of the front frame, in addition to the above effects, depending on the content of the intended work Since maintenance work etc. can be performed by opening either the upper or lower back mechanism board alone, only the back mechanism board (for example, the lower back mechanism board) according to the work purpose is selectively opened for work. The work efficiency can be improved.

さらに、下部裏機構盤の上端面の形状及び配設位置を、下部裏機構盤の前方に位置する遊技盤の下端面よりも下方に位置するように設定し、下部裏機構盤を前枠に閉止させた状態で遊技盤を収容枠に着脱可能に構成することにより、遊技盤の保守作業や盤面換え作業等において、下部裏機構盤を前枠に閉止させた状態のまま遊技盤を着脱することができ、付帯工数を含めた作業工数を大幅に削減することができる。   Furthermore, the shape and arrangement position of the upper end surface of the lower back mechanism board is set so as to be positioned below the lower end surface of the game board located in front of the lower back mechanism board, and the lower back mechanism board is used as the front frame. By configuring the game board so that it can be attached to and detached from the storage frame in the closed state, the game board can be attached and detached while the lower back mechanism board is closed to the front frame in game board maintenance work and board surface change work, etc. The work man-hours including incidental man-hours can be greatly reduced.

従って、以上のような本発明の盤構造によれば、余計な付帯工数をかけることなく、作業目的に応じて適切かつ迅速に作業を行うことができる弾球遊技機の盤構造を提供することができる。   Therefore, according to the board structure of the present invention as described above, it is possible to provide a board structure of a ball game machine capable of performing work appropriately and quickly according to the work purpose without taking extra man-hours. Can do.

If necessary, the surface treatment such as chromate treatment is performed. The outer peripheral edge of the base frame 410 is formed so that the end of the flat support plate portion 411 is bent backward and ribs 412, 412... Having a height of about 5 to 10 mm surround the periphery of the support plate portion. In addition, the bending rigidity is increased, and the entire front of the ball storage / dispensing assembly 420 and the ball passage assembly 430 is covered to enhance the electromagnetic shielding effect.

ベースフレーム410の右側縁部には、上下2箇所に上部裏機構盤ヒンジ部413,413が形成されている。上下の上部裏機構盤ヒンジ部は、ベースフレーム410が前方に水平に曲げ起こされて舌片状に突出するヒンジプレート413b,413bと、各ヒンジプレートの先端側にカシメ固着されて下方に突出するヒンジピン413c,413dとからなり、ベースフレーム410に一体に形成されている。上下のヒンジピン413c,413dは、下方のヒンジピン413dの方が上方のヒンジピン413cよりも幾分長めに設定されるとともに、各ヒンジピンの先端には先細円錐状の導入部が形成されている。   On the right edge of the base frame 410, upper back mechanism board hinges 413 and 413 are formed at two locations, upper and lower. The upper and lower upper back mechanism board hinges are hinge plates 413b, 413b that are bent and raised horizontally in the forward direction and project in a tongue-like shape, and are caulked and fixed to the tip side of each hinge plate and project downward. It consists of hinge pins 413c and 413d and is formed integrally with the base frame 410. The upper and lower hinge pins 413c and 413d are set such that the lower hinge pin 413d is slightly longer than the upper hinge pin 413c, and a tapered conical introduction portion is formed at the tip of each hinge pin.

一方、前枠2の右側縁に、上記上部裏機構盤ヒンジ部413,413に対応して、前枠側上ヒンジ金具213,213が取り付けられている。前枠側上ヒンジ金具は、前枠2の後面にネジ固定されたヒンジベース213a,213aと、このヒンジベースから水平に後方に突出する舌片状のヒンジプレート213b,213bとからなり、各ヒンジプレートの先端側にヒンジピン413c,413dの軸径よりもわずかに大きめの内径を有するピン受容孔213c,213dが穿設されている。前枠側上ヒンジ金具213,213は、上下のヒンジプレート213b,213bの配設間隔が、上部裏機構盤ヒンジ部のヒンジプレート413b,413bの間隔に合わせて前枠後面の所定高さ位置に配設される。   On the other hand, front frame side upper hinge fittings 213 and 213 are attached to the right edge of the front frame 2 corresponding to the upper back mechanism board hinge portions 413 and 413. The front-frame-side upper hinge fitting includes hinge bases 213a and 213a fixed to the rear surface of the front frame 2 by screws and tongue-like hinge plates 213b and 213b that protrude rearward horizontally from the hinge base. Pin receiving holes 213c and 213d having an inner diameter slightly larger than the shaft diameter of the hinge pins 413c and 413d are formed on the front end side of the plate. The front frame side upper hinge metal fittings 213 and 213 are arranged at a predetermined height position on the rear surface of the front frame so that the upper and lower hinge plates 213b and 213b are arranged in accordance with the interval between the hinge plates 413b and 413b of the upper back mechanism board hinge portion. Arranged.

なお、ベースフレーム410を、導電性のフィラー(例えば金属繊維や炭素繊維)を混入した樹脂材料を用いて一体的に成型し、その右側縁の上下2箇所に、上部裏機構盤ヒンジ部413,413と同様のヒンジプレート及びヒンジピンを有する上部裏機構盤ヒンジ金具をねじ固定するように構成しても良い。   The base frame 410 is integrally molded using a resin material mixed with a conductive filler (for example, metal fiber or carbon fiber), and the upper back mechanism board hinge part 413 is formed at two locations on the upper right and lower sides of the base frame 410. An upper back mechanism board hinge fitting having a hinge plate and a hinge pin similar to 413 may be fixed with screws.

球貯留払出アッセンブリ420は、入賞に対する褒賞としての遊技球(賞球)を貯留する貯留タンク部421a、貯留タンク部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425に導くタンクレール部421b、及び球払出装置425を着脱可能に装着保持する機構装着部421cを有し、導電性のフィラーを混入した樹脂材料を用いて一体成型されたアッセンブリベース421を基体とし、ここにタンクレール部421bの上方を覆うレールカバー423、タンクレール部421bの下流部に設けられて遊技球の流下を規制可能な球止め機構(不図示)、アッセンブリベースの機構装着部421cに設けられタンクレール部421bから導かれた遊技球を払い出す球払出装置425などが組付けられて構成される。   The ball storage / dispensing assembly 420 has a storage tank portion 421a for storing game balls (prize balls) as rewards for winning, and the game balls stored in the storage tank portion that are smoothly connected to the storage tank portion are aligned in a row. An assembly integrally formed using a resin material mixed with a conductive filler, having a tank rail portion 421b that leads to a lower ball dispensing device 425 and a mechanism mounting portion 421c that detachably mounts and holds the ball dispensing device 425 A base 421 is used as a base, and a rail cover 423 that covers the upper side of the tank rail portion 421b, a ball stop mechanism (not shown) that is provided downstream of the tank rail portion 421b and can regulate the flow of the game ball, and an assembly base A ball payout device 425 for paying out a game ball guided from the tank rail portion 421b provided in the mechanism mounting portion 421c is assembled. Configured are.

貯留タンク部421aは、平面視横長で上面及び右面開放の箱状をなし底面は緩く右傾してタンクレール部421bに繋がっている。タンクレール部421bは、平面視において貯留タンク部421の前後の壁面と滑らかに繋がり通路幅が徐々に絞られて狭くなるロート状をなし、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421b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421a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上下連通して開口する出口開口が形成されている。このため、タンクレール部を流下する遊技球が流下する過程で1列に整列され、出口開口から直下に位置する球払出装置425の導入口に導かれるようになっている。   The storage tank portion 421a is horizontally long in plan view and has a box shape with the top surface and the right surface open, and the bottom surface is gently inclined to the right and is connected to the tank rail portion 421b. The tank rail portion 421b has a funnel shape that is smoothly connected to the front and rear wall surfaces of the storage tank portion 421 in a plan view and gradually narrows down the passage width, and the bottom surface is inclined to the right with a slightly larger inclination angle than the storage tank portion. Formed. A downstream portion of the tank rail portion 421b has a U-shaped groove shape having a passage width slightly larger than the diameter of the game ball, and an alignment passage for aligning the game balls supplied from the storage tank portion 421a is formed. . Above the alignment passage, a weight-type ball leveling pendulum that leveles the game ball flowing down with the passage above and below is pivotally supported, and the downstream end of the alignment passage communicates vertically. An outlet opening is formed. For this reason, the game balls flowing down the tank rail portion are aligned in a row in the process of flowing down, and are guided from the outlet opening to the introduction port of the ball dispensing device 425 located immediately below.

球払出装置425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(貯留タンク部側から見た側面視において時計廻り・反時計廻り)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、アッセンブリベースの機構装着部421c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421bの出口開口と位置整合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 425 has a ball receiving groove for receiving a game ball on the 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-right direction. Assembly base mechanism mainly composed of a ball dispensing motor that rotates in a direction (clockwise or counterclockwise when viewed from the side viewed from the storage tank side), a ball feed rotating disk, and a housing that houses the ball dispensing motor. The mounting portion 421c is detachably mounted and held. The upper end of the housing is formed with an opening for receiving a game ball in alignment with the outlet opening of the tank rail 421b. The lower end of the housing has a first ball payout outlet at the rear and a second ball payout at the front. The outlet is formed in an opening side by side.

このため、導入口から導入された遊技球は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とともに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7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(上記同様に図7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。   For this reason, the game ball introduced from the introduction port is received in the ball receiving groove of the ball feed rotating disk in the housing and rolls backward or forward in the housing along with the rotation of the ball feeding rotating disk, It is paid out from the first ball payout exit or the second ball payout exit. 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. 7, 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 payout motor is reversed and the ball feed rotating disk is rotated in the reverse direction (same as above, counterclockwise in the side view shown in FIG. 7, the same applies hereinafter), the game ball received in the ball receiving groove is The inside of the housing rolls counterclockwise with the rotation of the feed turntable and is paid out from the second ball payout outlet in front of the lower end portion of the housing.

球払出装置425は、下部裏機構盤45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払い出させるように構成した例を示している。なお遊技作動時における球払出装置45の具体的な制御形態については後に説明する。   The operation of the ball dispensing device 425 is controlled by a ball dispensing control board 82 attached to the lower back mechanism board 45, and the ball feeding device 425 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. An example is shown in which the ball feed rotating disk is sometimes rotated counterclockwise so that the game ball is paid out from the front second ball payout opening. A specific control form of the ball payout device 45 during the game operation will be described later.

球通路アッセンブリ430は、全体として前後方向幅が比較的厚く左右方向幅が狭い矩形断面で上下方向に長い桟状をなし、上下の端部が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430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431と、この通路形成部材の開放面を覆う通路カバー432などからなり、球払出装置425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 430 as a whole has a rectangular cross section with a comparatively thick front-rear width and a narrow left-right width, and is formed in a cross-shaped shape that is long in the vertical direction. Yes. The ball passage assembly 430 is composed of a passage forming member 431 having a left side opened and formed with two front and rear bent passage grooves, a passage cover 432 covering the open surface of the passage forming member, and the like. The game balls paid out from the device 425 are caused to roll down along the two rows of the front and rear ball passages and led to the first outlet or the second outlet at the lower end.

通路形成部材431には、図7に示すように、前後に蛇行しつつ上下に延びるリブ状の中央通路壁431cと、この中央通路壁431cの前方及び後方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431f及び後方通路壁431rを有し、中央通路壁431cを挟む前後に各1列の蛇行した平断面視凹状の通路溝を形成する。そして通路形成部材431の開放面に通路カバー432を取り付けることで、前後2列の球通路435,436が形成され、球通路アッセンブリ430が構成される。   As shown in FIG. 7, the passage forming member 431 has a rib-like central passage wall 431c that meanders back and forth while extending vertically, and is slightly larger than the diameter of the game ball in front and rear of the central passage wall 431c. A front passage wall 431f and a rear passage wall 431r extending up and down substantially parallel to each other are formed, and one row of meandering passage grooves each having a concave shape in plan view are formed before and after sandwiching the central passage wall 431c. Then, by attaching the passage cover 432 to the open surface of the passage forming member 431, the front and rear two rows of ball passages 435 and 436 are formed, and the ball passage assembly 430 is formed.

球通路アッセンブリの上端部において上方に開口する球通路435の入り口(第1球入り口)435a及び球通路436の入り口(第2球入り口)436aは、それぞれ球払出装置425の第1球払出口及び第2球払出口の配設位置に合わせて形成されており、後列側の球通路435が賞球としての遊技球を球皿6,7に導く球払出通路、前列側の球通路436が遊技球を機体の外部に導く球抜き通路になっている。   The entrance (first sphere entrance) 435a and the entrance (second sphere entrance) 436a of the ball passage 435 opening upward at the upper end of the ball passage assembly are respectively a first ball discharge outlet of the ball discharge device 425 and The ball passage 435 on the rear row side is formed in accordance with the arrangement position of the second ball payout outlet, the ball payout passage for guiding the game balls as prize balls to the ball trays 6 and 7, and the ball passage 436 on the front row side. It is a ball passage that guides the ball to the outside of the aircraft.

球通路アッセンブリ430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431の右側面がベースフレーム410の右側縁に合わせて形成されている。またベースフレーム410の左側縁はこのように右側に寄せられた球通路アッセンブリの左側面に合わせて形成され、上部裏機構盤41の左右方向幅が球払出装置近傍の幅よりも狭くなっている。このため、第1及び第2球入り口435a,436aから流入した遊技球の落下速度が屈曲部で緩和されるとともに、上部裏機構盤41の幅が狭小化された領域で遊技盤30の後面側に広いスペースを確保でき、例えば、遊技盤30に配設される入賞装置の配設位置の自由度を拡大し、あるいは遊技盤30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。   The ball passage assembly 430 is bent right diagonally downward just below the ball entrance, and the right side surface of the passage forming member 431 is formed to match the right edge of the base frame 410. Further, the left side edge of the base frame 410 is formed in accordance with the left side surface of the ball passage assembly that is brought to the right side in this way, and the lateral width of the upper back mechanism board 41 is narrower than the width in the vicinity of the ball dispensing device. . For this reason, the falling speed of the game balls flowing in from the first and second ball entrances 435a and 436a is moderated by the bent portion, and the rear side of the game board 30 in the region where the width of the upper back mechanism board 41 is narrowed. A wide space can be secured, for example, the degree of freedom of the arrangement position of the winning device arranged on the game board 30 is expanded, or the size and arrangement position of various circuit boards attached to the back side of the game board 30 The degree of freedom can be expanded.

球通路アッセンブリ430の上下中間部では、球抜き通路436及び球払出通路435が中央通路壁431cを挟んで隣接し、前後平行に複数回折り返されて蛇行形成されている。このため、上下に延びるこれらの球通路を転動流下する遊技球の速度を過度に増加させることなく軽快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。   In the middle of the upper and lower parts of the ball passage assembly 430, a ball removal passage 436 and a ball discharge passage 435 are adjacent to each other with the central passage wall 431c interposed therebetween, and are bent in a plurality of directions in parallel in the front-rear direction. For this reason, it is possible to lightly flow down without excessively increasing the speed of the game balls rolling down these ball passages extending vertically, and the thickness in the front-rear direction with a simple structure while being a plurality of ball passages. The configuration is minimized.

球通路アッセンブリ430の下部は、左斜め下方に折り曲げられて球払出通路435及び球抜き通路436が傾斜通路とされ、球通路アッセンブリ430の下端部に下方に開く第1球出口435b,第2球出口436bが形成される。球払出通路435の出口である第1球出口435bと球抜き通路436の出口である第2球出口436bとは前後左右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通路436の第2球出口436bが前方右側に、傾斜通路が長く形成された球払出通路435の第1球出口435bが後方左側に位置して配設される。   A lower portion of the ball passage assembly 430 is bent obliquely downward to the left to form a ball discharge passage 435 and a ball removal passage 436 as inclined passages, and a first ball outlet 435b and a second ball opened downward to the lower end of the ball passage assembly 430. An outlet 436b is formed. The first ball outlet 435b, which is the outlet of the ball payout passage 435, and the second ball outlet 436b, which is the outlet of the ball discharge passage 436, are offset to the front, rear, left and right, and the first ball outlet passage 436 having a short inclined passage is formed. The two-ball outlet 436b is disposed on the front right side, and the first ball outlet 435b of the ball dispensing path 435 formed with a long inclined path is positioned on the rear left side.

このように構成される球貯留払出アッセンブリ420及び球通路アッセンブリ430は、それぞれベースフレーム410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一体の上部裏機構盤41が形成される。上部裏機構盤41は、ベースフレーム410の右側縁上下に設けられた上部裏機構盤ヒンジ部413,413と前枠2の右側縁上下に取り付けられた前枠側上ヒンジ金具213,213のヒンジピンとピン受容孔との嵌合を利用して前枠2の裏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 420 and the ball passage assembly 430 configured as described above are screwed to the upper and lower portions of the base frame 410, respectively, and are integrated upper portions having functions for storing, discharging, stopping and removing the ball. A back mechanism board 41 is formed. The upper back mechanism board 41 has hinge pins of upper back mechanism board hinge parts 413 and 413 provided above and below the right edge of the base frame 410 and front frame side upper hinge fittings 213 and 213 attached above and below the right edge of the front frame 2. And the pin receiving hole are detachably mounted on the back side of the front frame 2 and are arranged to be opened and closed laterally rearward in a hinged state.

ここで、上部裏機構盤ヒンジ部413,413における上下のヒンジプレート413b,413bの間隔と、前枠側上ヒンジ金具213,213における上下のヒンジプレート213b,213bの間隔とは同一に設定される一方、上部裏機構盤ヒンジ部413,413における上下のヒンジピン413c,413dにはピン先端部に円錐状の導入部が形成されるとともに、ヒンジピンの長さは下方のヒンジピン413dの方が長く形成されている。このため、上部裏機構盤ヒンジ部413,413と前枠側上ヒンジ金具213,213とを連結させる際には、まず下方のヒンジピン413dとピン受容孔213dに着目してこれらを先に位置合わせして嵌合させ、次いで上方のヒンジピン413cとピン受容孔213cを位置合わせして嵌合させればよく、容易に上下2箇所のヒンジ部とヒンジ金具とを嵌合させてヒンジ連結できるようになっている。   Here, the distance between the upper and lower hinge plates 413b and 413b in the upper back mechanism board hinge portions 413 and 413 and the distance between the upper and lower hinge plates 213b and 213b in the front frame side upper hinge fittings 213 and 213 are set to be the same. On the other hand, the upper and lower hinge pins 413c and 413d in the upper back mechanism board hinge portions 413 and 413 are formed with a conical introduction portion at the tip of the pin, and the length of the lower hinge pin 413d is longer. ing. For this reason, when connecting the upper back mechanism board hinges 413 and 413 and the front frame side upper hinge fittings 213 and 213, first, focus on the lower hinge pin 413d and the pin receiving hole 213d and align them first. And then the upper hinge pin 413c and the pin receiving hole 213c may be aligned and fitted so that the upper and lower hinge portions and the hinge fitting can be easily fitted and hinged. It has become.

上部裏機構盤41は、上記のように上部裏機構盤41を前枠2の裏面側にヒンジ連結させた状態で、上部裏機構盤41の上端(ベースフレーム410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配設されてこれらの間に数mm程度のクリアランスが確保され、上部裏機構盤41の下端(球通路アッセンブリ430の下端)が収容枠に収容された遊技盤30の下端面(化粧板31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 41 is hinge-connected to the back side of the front frame 2 as described above, the upper end of the upper back mechanism board 41 (the upper end of the base frame 410) is in the outer frame 1.

For example, a steel sheet having a thickness of about 1.2 to 2.3 mm is formed by punching, bending, caulking, etc., and subjected to a predetermined surface treatment as necessary.

プレート部481には、ベースプレート部451の後面側に形成された基盤取り付け部の各装着構造の配設位置に合わせて、ベース側フック部や支持脚受容穴及び支持脚固定ネジ等の各係合部を後方に挿通させる係合部挿通孔が開口形成されるとともに、プレート部481及び屈曲部482の前後面に、ベースプレート部451及びヒンジ台座452に形成されたネジ孔の形成位置に合わせて、シールド板480を固定するためのネジ488を挿通させるネジ挿通孔が形成されている。   The plate portion 481 has various engagements such as a base-side hook portion, a support leg receiving hole, and a support leg fixing screw in accordance with the arrangement position of each mounting structure of the base mounting portion formed on the rear surface side of the base plate portion 451. An engagement portion insertion hole that allows the portion to be inserted rearward is formed, and in accordance with the formation positions of the screw holes formed in the base plate portion 451 and the hinge base 452 on the front and rear surfaces of the plate portion 481 and the bent portion 482, A screw insertion hole for inserting a screw 488 for fixing the shield plate 480 is formed.

プレート部481の左端側は、球払出制御基盤82の装着位置よりも左方に延出されて後面側が開放された放熱部486が形成されている。放熱部486の左端上部には一部がZ字状に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487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と嵌合させることで、複数の回路基盤に対して1本のアース線で簡単に接続できるとともに、シールド部材480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。   The left end side of the plate portion 481 is formed with a heat radiating portion 486 that extends leftward from the mounting position of the ball payout control base 82 and is open on the rear side. A connection terminal portion 487 is formed on the upper left end of the heat radiating portion 486, part of which is cut and raised in a Z-shape and set to a male terminal shape of a plug-in connection terminal (for example, E78965 in the UL standard). By fitting with a female plug-in connection terminal crimped to the end of the ground wire, it can be easily connected to a plurality of circuit boards with a single ground wire, and the shield member 480 can be reliably connected to the ground potential. It is possible to obtain a stable and sufficient shielding effect by dropping the ground.

プレート部481の右端側は、電源基盤83の装着位置よりも右方に延出されてヒンジ台座452の前後面及び右側面を囲む平面視コの字状の屈曲部482が形成されており、前後面及び右側面が開放された放熱部としても機能する。そしてヒンジ台座452の前方座面を覆う屈曲部482の前方辺に、下部裏機構盤ヒンジ部483,483が形成されている。   A right end side of the plate portion 481 is formed in a U-shaped bent portion 482 extending in the right direction from the mounting position of the power supply base 83 and surrounding the front and rear surfaces and the right side surface of the hinge base 452. It also functions as a heat dissipating part with open front and rear surfaces and right side surface. Lower back mechanism board hinge portions 483 and 483 are formed on the front side of the bent portion 482 that covers the front seat surface of the hinge base 452.

下部裏機構盤ヒンジ部483,483は、屈曲部482の前方辺の上下が水平に切り起こされて前方に突出する舌片状のヒンジプレート483b,483bと、各ヒンジプレートの先端側にカシメ固着されて下方に突出するヒンジピン483c,483dとからなり、シールド部材480に一体に形成されている。上下のヒンジピン483c,483dは、下方のヒンジピン483dの方が上方のヒンジピン483cよりも幾分長めに設定されるとともに、各ヒンジピンの先端には先細円錐状の導入部が形成されている。   The lower back mechanism board hinges 483 and 483 are formed by tongue-like hinge plates 483b and 483b that are projected forward by horizontally cutting and raising the front side of the bent part 482, and crimped to the tip side of each hinge plate. The hinge pins 483c and 483d projecting downward are formed integrally with the shield member 480. The upper and lower hinge pins 483c and 483d are set so that the lower hinge pin 483d is somewhat longer than the upper hinge pin 483c, and a tapered conical introduction portion is formed at the tip of each hinge pin.

一方、前枠2の右側縁に、下部裏機構盤ヒンジ部483,483に対応して、前枠側下ヒンジ金具283,283が取り付けられている。前枠側下ヒンジ金具は、前枠2の後面にネジ固定されたヒンジベース283a,283aと、このヒンジベースから水平に後方に突出する舌片状のヒンジプレート283b,283bとからなり、各ヒンジプレートの先端側にヒンジピン483c,483dの軸径よりもわずかに大きめの内径を有するピン受容孔283c,283dが穿設されている。前枠側下ヒンジ金具283,283は、上下のヒンジプレート283b,283bの配設間隔が、下部裏機構盤ヒンジ部のヒンジプレート483b,483bの間隔に合わせて前枠後面の所定高さ位置に配設される。   On the other hand, front frame side lower hinge fittings 283 and 283 are attached to the right edge of the front frame 2 corresponding to the lower back mechanism board hinge portions 483 and 483. The lower hinge bracket on the front frame side includes hinge bases 283a and 283a fixed to the rear surface of the front frame 2 and tongue-like hinge plates 283b and 283b that protrude rearward horizontally from the hinge base. Pin receiving holes 283c and 283d having an inner diameter slightly larger than the shaft diameter of the hinge pins 483c and 483d are formed on the front end side of the plate. The front frame side lower hinge fittings 283 and 283 are arranged so that the upper and lower hinge plates 283b and 283b are arranged at a predetermined height position on the rear surface of the front frame in accordance with the interval between the hinge plates 483b and 483b of the lower back mechanism board hinge. Arranged.

シールド部材480は、プレート部481を下部ベースのベースプレート部451に載置して左方にスライドさせ、コの字状の屈曲部482をヒンジ台座452の前後面を挟むように係合させて、ヒンジ台座452の前後面およびベースプレート部451の各部に形成されたネジ受容穴にネジ488を螺合させて締め込むことで、下部ベース450に一体的に固定され、ベースプレート部451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関係の構造を有する下部裏機構盤45が形成される。下部裏機構盤45は、下部ベース450の右側縁上下に設けられた下部裏機構盤ヒンジ部483,483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283,283のヒンジピンとピン受容孔との嵌合を利用して前枠2の裏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 shield member 480 is configured such that the plate portion 481 is placed on the base plate portion 451 of the lower base and slid to the left, and the U-shaped bent portion 482 is engaged so as to sandwich the front and rear surfaces of the hinge base 452. A screw 488 is screwed into and tightened into a screw receiving hole formed in each of the front and rear surfaces of the hinge base 452 and the base plate portion 451 so as to be integrally fixed to the lower base 450 and mainly on the front side of the base plate portion 451. A lower back mechanism board 45 having a ball processing-related structure for flowing down the game ball and a board-related structure in which a circuit board is mainly mounted on the rear surface side is formed. The lower back mechanism board 45 includes hinge pins of lower back mechanism board hinge portions 483 and 483 provided above and below the right edge of the lower base 450 and front frame side lower hinge fittings 283 and 283 attached above and below the right edge of the front frame 2. And the pin receiving hole are detachably mounted on the back side of the front frame 2 and are arranged to be opened and closed laterally rearward in a hinged state.

ここで、下部裏機構盤ヒンジ部483及び前枠側下ヒンジ金具283の上下ヒンジプレートの配設間隔が同一に設定される一方、下部裏機構盤ヒンジ部483における上下のヒンジピン483c,483dの長さは、下方のヒンジピン483dの方が上方のヒンジピン483bよりも長く形成されている。このため、下部裏機構盤ヒンジ部483と前枠側上ヒンジ金具283とを連結させる際に、まず下方のヒンジピン483dとピン受容孔283dに着目してこれらを先に嵌合させ、次いで上方のヒンジピン483cとピン受容孔283cを嵌合させればよく、容易に上下2箇所のヒンジ部とヒンジ金具とを嵌合させてヒンジ連結できるようになっている。   Here, the arrangement intervals of the upper and lower hinge plates of the lower back mechanism board hinge portion 483 and the front frame side lower hinge fitting 283 are set to be the same, while the lengths of the upper and lower hinge pins 483c and 483d in the lower back mechanism board hinge portion 483 are set. The lower hinge pin 483d is longer than the upper hinge pin 483b. For this reason, when connecting the lower back mechanism board hinge part 483 and the front frame side upper hinge metal fitting 283, first focusing on the lower hinge pin 483d and the pin receiving hole 283d, and then fitting them first. The hinge pin 483c and the pin receiving hole 283c only have to be fitted, and the hinge parts at the upper and lower two places and the hinge fitting can be easily fitted to be hinged.

下部裏機構盤45は、上記のように下部裏機構盤45を前枠2の裏面側にヒンジ連結させた状態で、下部裏機構盤45の上端(下部ベース450の上端)が収容枠に収容された遊技盤30の下端面(化粧板31の下端面)よりも下方に位置し、下部裏機構盤45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、下部裏機構盤45をヒンジ連結させた状態で遊技盤30は下部裏機構盤45よりも上方に位置しており、上部裏機構盤41を開放すれば下部裏機構盤45を前枠2に閉止させた状態のままで、遊技盤30を収容枠に着脱することができる。   In the lower back mechanism board 45, the upper end of the lower back mechanism board 45 (the upper end of the lower base 450) is housed in the housing frame in a state where the lower back mechanism board 45 is hinged to the back side of the front frame 2 as described above. The lower board surface of the game board 30 is positioned below the lower surface (the lower surface of the decorative plate 31), and the lower edge of the lower back mechanism board 45 is positioned above the upper surface of the curtain plate in the outer frame 1. Yes. For this reason, the game board 30 is positioned above the lower back mechanism board 45 with the lower back mechanism board 45 hinged, and if the upper back mechanism board 41 is opened, the lower back mechanism board 45 is moved to the front frame. The game board 30 can be attached to and detached from the storage frame while being kept closed to 2.

そして、上記のように前枠2の裏面側に開閉可能にヒンジ連結された上部裏機構盤41及び下部裏機構盤45を前枠2の後方を覆うように閉止し、上部裏機構盤41におけるベースフレーム410の上部、下部裏機構盤45における下部ベース450の左部に設けられた各閉止保持部材、例えば図示するナイロンファースナー418,458を利用して閉鎖状態に係止保持させる。そして、下部裏機構盤45におけるプレート部後面の基盤装着部に、基盤ケースに収められた球払出制御基盤82及び電源基盤83を装着固定し、これらの回路基盤とパチンコ機の各部に取り付けられた他の回路基盤、あるいは球払出装置425等の電気部品とをコネクタ接続することでパチンコ機PMが構成される。   Then, as described above, the upper back mechanism board 41 and the lower back mechanism board 45 hinged to be openable and closable on the back side of the front frame 2 are closed so as to cover the rear of the front frame 2, and the upper back mechanism board 41 Each of the closing holding members provided on the upper portion of the base frame 410 and the left portion of the lower base 450 in the lower back mechanism board 45, for example, nylon fursners 418 and 458 shown in the figure, are used to be locked and held. Then, the ball payout control base 82 and the power base 83 housed in the base case are mounted and fixed to the base mounting part on the rear surface of the plate part in the lower back mechanism board 45, and attached to each part of the circuit base and the pachinko machine. The pachinko machine PM is configured by connecting other circuit boards or electrical components such as the ball payout device 425 with connectors.

ところで、下部裏機構盤45の前方に位置する前枠裏面側では、前枠2から後方に突出して上面及び前面開放の箱状の賞球出口樋235が形成されており、上球皿6の閉鎖姿勢において前方に位置する上球皿の皿本体と繋がっている。また賞球出口樋235は、上下の裏機構盤41,45が閉鎖されると、下部裏機構盤45における左右の集合樋455,455の間に位置して配設され、賞球出口樋235の開口直上に上部裏機構盤41における球払出通路435の第1球出口435bが、賞球出口樋235よりも右側の上方に上部裏機構盤41における球抜き通路436の第2球出口436bが配設される。   By the way, on the back side of the front frame located in front of the lower back mechanism board 45, a box-shaped prize ball exit bar 235 that protrudes rearward from the front frame 2 and is open on the upper surface and the front surface is formed. In the closed position, it is connected to the main body of the upper ball tray located forward. Further, the prize ball exit bowl 235 is disposed between the left and right collective bowls 455 and 455 in the lower back mechanism board 45 when the upper and lower back mechanism boards 41 and 45 are closed. A first ball outlet 435b of the ball payout passage 435 in the upper back mechanism board 41 is located immediately above the opening of the upper back mechanism board 41, and a second ball outlet 436b of the ball removal passage 436 in the upper back mechanism board 41 is located on the upper right side of the prize ball outlet bowl 235. Arranged.

すなわち、上下の裏機構盤41,45の閉鎖姿勢では、上部裏機構盤41の第1球出口435bが賞球出口樋235の直上に位置して球払出通路435が賞球出口樋235を介して上球皿6に繋がり、上部裏機構盤41の第2球出口436bが賞球出口樋235の側部上方に位置して球抜き通路436が遊技済み球通路456に繋がるように配設される。   That is, in the closed posture of the upper and lower back mechanism boards 41, 45, the first ball outlet 435 b of the upper back mechanism board 41 is positioned immediately above the prize ball outlet bowl 235, and the ball payout passage 435 passes through the prize ball outlet bowl 235. And the second ball outlet 436b of the upper back mechanism board 41 is located above the side of the prize ball outlet bowl 235 so that the ball removal passage 436 is connected to the game-completed ball passage 456. The

このため、遊技盤30において所定の入賞条件が成立すると、球払出制御基盤82から球払出装置425に入賞条件に応じた球払出指令信号が出力され、これを受けた球払出装置425が球払出指令信号に基づいて球送り回転盤を正方向に所定回転角度分(例えば払い出される遊技球の球数で13個に相当する回転角度分)だけ回転作動させて、第1球払出口から遊技球を払い出させる。払い出された遊技球は、前後に蛇行する球払出通路435を通って流下速度が緩和され、下端の第1球出口435bから賞球出口樋235に落下しこの賞球出口樋235に案内されて上球皿6に流下する。   For this reason, when a predetermined winning condition is established in the game board 30, a ball payout command signal corresponding to the winning condition is output from the ball payout control base 82 to the ball payout device 425, and the ball payout device 425 receiving the ball payout device 425 receives this. Based on the command signal, the ball feeding rotary disk is rotated in the forward direction by a predetermined rotation angle (for example, a rotation angle corresponding to 13 game balls to be paid out) to play a game ball from the first ball payout exit. To pay out. The game balls that have been paid out pass through the ball payout passage 435 meandering back and forth, the flow speed is reduced, and the game balls are dropped from the first ball outlet 435b at the lower end to the prize ball exit bowl 235 and guided to the prize ball exit bowl 235. Then flow down to the upper ball tray 6.

一方、遊技盤30において何れかの入賞装置に落入したセーフ球、及び入賞装置に落入することなく遊技領域PAの下端まで落下してアウト口38から排出されたアウト球は、下部裏機構盤45の集合樋455に受け止められて遊技済み球排出通路456に集合され、この通路下端の球排出口456bから基体外部(遊技島の球回収装置)に排出される。   On the other hand, the safe ball dropped into any winning device on the game board 30 and the out ball dropped to the lower end of the game area PA without falling into the winning device and discharged from the out port 38 are the lower back mechanism. The balls 45 are received by the collecting bowl 455 of the board 45 and gathered in the game-completed ball discharge passage 456, and discharged from the ball discharge port 456b at the lower end of the passage to the outside of the base (the ball collection device on the game island).

また、パチンコ機PMにおいて所定の球抜き操作、例えばハートキーと称される作業用の操作ピンによりパチンコ機の前面側から機体内部の球抜きスイッチが押圧操作されて、球払出制御基盤82から球払出装置425に球抜き指令信号が出力されると、球払出装置425は球抜き指令信号に基づいて球送り回転盤を逆方向に所定回転角度分(例えば貯留タンク部421aに貯留された遊技球を全量排出させる時間に相当する回転角度分)だけ回転作動させて、第2球払出口から遊技球を払い出させる。払い出された遊技球は、前後に蛇行する球抜き通路436を通って流下速度が緩和され、下端の第2球出口436bから集合樋455に落下し遊技済み球排出通路456を通って下端の球排出口456bから基体外部に排出される。   Also, a predetermined ball removal operation in the pachinko machine PM, for example, a ball removal switch inside the machine body is pressed from the front side of the pachinko machine by a work operation pin called a heart key, and the ball payout control base 82 When a ball removal command signal is output to the payout device 425, the ball payout device 425 moves the ball feed rotary disk in the reverse direction by a predetermined rotation angle (for example, a game ball stored in the storage tank unit 421a) based on the ball removal command signal. The game ball is paid out from the second ball payout opening by rotating the rotation by the rotation angle corresponding to the time for discharging the entire amount. The paid-out game balls are slowed down the flow velocity through the ball passage 436 meandering back and forth, fall from the second ball outlet 436b at the lower end to the collecting bowl 455, and pass through the game-completed ball discharge passage 456 at the lower end. It is discharged out of the substrate from the ball discharge port 456b.

以上のように構成されるパチンコ機PMでは、裏機構盤が上部裏機構盤41と下部裏機構盤45とからなり、それぞれ独立して前枠2の後方に着脱及び開閉が可能に取り付けられている。このため、パチンコ機PMの保守作業や点検作業等を行おうとする作業者は、目的とする作業内容に応じて上下何れかの裏機構盤を単独で開放して効率的に作業を行うことができる。例えば、遊技盤30の裏面側に設けられた入賞検出器を交換するような場合には上部裏機構盤41のみを開放して交換作業を行い、前枠下部の裏面側に設けられた遊技球発射装置9のロータリーソレノイドや発射制御基盤の保守作業を行う場合には下部裏機構盤45のみを開放して保守作業を行うことができる。   In the pachinko machine PM configured as described above, the back mechanism panel is composed of the upper back mechanism panel 41 and the lower back mechanism panel 45, which are independently attached to the rear of the front frame 2 so as to be detachable and openable. Yes. For this reason, an operator who wants to perform maintenance work, inspection work, etc. of the pachinko machine PM can efficiently work by opening either the upper or lower back mechanism panel depending on the intended work content. it can. For example, when a prize detector provided on the back side of the game board 30 is to be exchanged, only the upper back mechanism board 41 is opened and exchange work is performed, and a game ball provided on the back side of the lower part of the front frame. When performing maintenance work on the rotary solenoid of the launching device 9 or the launch control board, only the lower back mechanism panel 45 can be opened to perform the maintenance work.

また本構成のパチンコ機PMでは、下部裏機構盤45の上端面の形状及び配設位置を、下部裏機構盤45の前方に位置する遊技盤30の下端面よりも下方に位置するように設定し、下部裏機構盤45を前枠に閉止させた状態で遊技盤30を収容枠に着脱可能に構成している。このため、遊技盤30を取り外して行う保守作業や、遊技盤30を着脱交換する盤面換え作業等において、下部裏機構盤45を前枠2に閉止させた状態のまま遊技盤30を着脱することができ、付帯工数を含めた作業工数を大幅に削減することができる。   Further, in the pachinko machine PM of this configuration, the shape and arrangement position of the upper end surface of the lower back mechanism board 45 are set to be lower than the lower end face of the game board 30 positioned in front of the lower back mechanism board 45. The game board 30 is configured to be detachable from the housing frame in a state where the lower back mechanism board 45 is closed to the front frame. For this reason, in the maintenance work performed by removing the game board 30 or the board surface changing work for attaching and detaching the game board 30, the game board 30 is attached and detached while the lower back mechanism board 45 is closed to the front frame 2. The work man-hours including incidental man-hours can be greatly reduced.

下部裏機構盤45では、下部裏機構盤の後面側に球払出制御基盤82及び電源基盤83を装着する基板装着部460を設け、これら複数の回路基板の前方を一体的に覆うシールド部材480を設けている。シールド部材480は球払出制御基盤82及び電源基盤83を合わせた装着面積よりも大きく形成し、シールド部材480の左右側部がこれらの回路基盤82,83の前方からそれぞれ左右側方に延びて配設されるように構成している。このため、両回路基板の間を通って斜めに入射しようとする電気的ノイズを遮断するとともに、両回路基盤の左右側方から斜めに入射しようとする電気的ノイズを低減することができ、ノイズに対する耐性を高めたパチンコ機を提供することができる。また、左右側方に延出されたシールド部材480の後面を開放状態とし、回路基板が発生した熱を放出する放熱部486等を形成することで、熱だまりの問題を解決して回路基板の冷却効果を向上させることができる。   In the lower back mechanism board 45, a board mounting portion 460 for mounting the ball payout control base 82 and the power supply base 83 is provided on the rear side of the lower back mechanism board, and a shield member 480 that integrally covers the front of the plurality of circuit boards is provided. Provided. The shield member 480 is formed larger than the combined mounting area of the ball payout control base 82 and the power supply base 83, and the left and right sides of the shield member 480 extend from the front of the circuit bases 82 and 83 to the left and right sides, respectively. It is configured to be installed. For this reason, it is possible to cut off the electrical noise that is going to enter diagonally through both circuit boards, and to reduce the electrical noise that is going to enter obliquely from the left and right sides of both circuit boards. It is possible to provide a pachinko machine with increased resistance to the above. In addition, the rear surface of the shield member 480 extending to the left and right sides is opened, and the heat dissipation part 486 and the like for releasing the heat generated by the circuit board are formed, thereby solving the problem of heat accumulation and the circuit board. The cooling effect can be improved.

さらに、電源基板83の前方から右方に延びるシールド部材480の屈曲部に、前枠側下ヒンジ金具283と係合連結して下部裏機構盤45を開閉可能に支持させる下部裏機構盤ヒンジ部483を形成することで、下部裏機構盤全体の構成を簡明化して生産コストを低減できるとともに、ヒンジ機構を含めた下部裏機構盤の強度を向上させることができる。また下部裏機構盤ヒンジ部483が放熱部としても機能するため、回路基板の冷却効果を向上させることができる。なおシールド部材480が互いのヒンジプレートを介して前枠側下ヒンジ金具283に電気的に接続されるため、前述した接続端子部487に代えて、前枠側下ヒンジ金具283にアース線を固定しても良く、このような構成によれば着脱及び揺動開閉される下部裏機構盤45のシールド部材480にアース線を張り渡して配線するよりも更に組み立て作業を容易化することができる。   Further, a lower back mechanism board hinge portion that engages and connects with the front frame side lower hinge fitting 283 to a bent portion of the shield member 480 extending rightward from the front of the power supply board 83 and supports the lower back mechanism board 45 so as to be opened and closed. By forming 483, the overall structure of the lower back mechanism board can be simplified to reduce production costs, and the strength of the lower back mechanism board including the hinge mechanism can be improved. Moreover, since the lower back mechanism board hinge part 483 functions also as a thermal radiation part, the cooling effect of a circuit board can be improved. Since the shield member 480 is electrically connected to the front frame side lower hinge fitting 283 via the hinge plates, the ground wire is fixed to the front frame side lower hinge fitting 283 instead of the connection terminal portion 487 described above. Alternatively, according to such a configuration, the assembling work can be further facilitated than the case where the ground wire is stretched over the shield member 480 of the lower back mechanism board 45 that is attached, detached, or swingably opened and closed.

従って、以上説明したような本発明の盤構造によれば、余計な付帯工数をかけることなく作業目的に応じて適切かつ迅速に作業を行うことができるとともに、部品点数や組立工数を削減してパチンコ機の生産コストを低減しつつ電気的なノイズに対するシールド効果を向上させた弾球遊技機の盤構造を提供することができる。   Therefore, according to the panel structure of the present invention as described above, the work can be performed appropriately and quickly according to the work purpose without taking extra incidental man-hours, and the number of parts and assembly man-hours can be reduced. It is possible to provide a board structure for a ball game machine that improves the shielding effect against electrical noise while reducing the production cost of pachinko machines.
