Description

【０００１】
【産業上の利用分野】
本発明は、景品球や貸球を遊技客に払い出すパチンコ球放出装置に関する。
【０００２】
【従来の技術】
一般に、パチンコ機の機構板には、パチンコ球の流れ順に、パチンコ球を貯める球タンクと、球タンクのパチンコ球を複数列に分けて流すパチンコ球導出樋と、該パチンコ球導出樋の流下端に接続するパチンコ球放出装置と、該パチンコ球放出装置に連通してパチンコ球を景品球や貸球として上球皿（図示せず）に導くパチンコ球排出樋が設けられている。
【発明が解決しようとする課題】
前記パチンコ球放出装置は、複数列に分かれているパチンコ球導出樋にそのまま接続することができ、一個単位での放出が可能で低コストであるのが望ましい。
【０００３】
【課題を解決するための手段】
本発明は上記に鑑みなされたもので、パチンコ球が通る球通路と、該球通路内に爪車の係合爪を臨ませてパチンコ球の流れを制御する球制御用回転体とを有し、前記球通路の上流側を複列構造に形成すると共に球通路の下流側を単列構造に形成し、球通路の上流側にあるパチンコ球の球圧が球制御用回転体のほぼ回転中心に向かって作用するように球通路の上流側と球制御用回転体の配置を設定し、前記球制御用回転体をモータ駆動により回転させて球通路の上流側の各列から下流側に対して一個ずつ交互にパチンコ球を流出させるようになし、さらに球通路の終端にパチンコ球一個分の広さの球出口を形成すると共に球通路の下流側に前記球出口に向けてパチンコ球を誘導する誘導部を設けたパチンコ球放出装置を提供する。
【０００４】
【作用】
球通路の上流側が複列構造になっているため、複数列のパチンコ球導出樋にそのまま接続することができる。そして、球制御用回転体が各列から交互に一個ずつパチンコ球を流出させると、それが誘導部に案内されてパチンコ球一個分の広さの球出口を通ってパチンコ球排出樋に放出される。従って球出口を通過するパチンコ球を検出すれば、球通路の上流側が複列構造になっていても一つのスイッチでパチンコ球の放出を検出することができる。
【０００５】
【実施例】
以下に本発明の実施例を図面を参照しつつ説明する。なお、図１はパチンコ球放出装置の一部切欠斜視図、図２はパチンコ球放出装置の縦断面図、図３は図２のＷ−Ｗ線断面図、図４は図２のＸ−Ｘ線断面図、図５はパチンコ機の裏面図である。
【０００６】
図５において、パチンコ機Ｐの機構板１には、パチンコ球の流れ順に、パチンコ球を貯める球タンク２と、球タンク２のパチンコ球を流すパチンコ球導出樋３と、該パチンコ球導出樋３の流下端に接続するパチンコ球放出装置４と、該パチンコ球放出装置４に連通してパチンコ球を景品球や貸球として上球皿（図示せず）に導くパチンコ球排出樋５が設けられている。
【０００７】
また、機構板１にはさらに、入賞したパチンコ球（入賞球）を集める入賞球集合樋６と、該入賞球集合樋６の入賞球を一個づつ処理して入賞信号を発する入賞球処理装置７が設けられている。
【０００８】
パチンコ球放出装置４は、前記のようにパチンコ球導出樋３とパチンコ球排出樋５の間に介装されており、二枚のプレート８ｆ，８ｒ間に形成した球通路９によって両樋３，５を結ぶ。球通路９は、上流側の入口通路９ａ，中間の球切り通路９ｂ，下流側の排出通路９ｃに区分される。入口通路９ａは、中央の仕切板９ｄを介して二列に区画された複列構造になっており、側面にパチンコ球検出用の近接スイッチ１０，１０を有する。一方、下流側の排出通路９ｃは、仕切のない単列構造になっており、図２に示すように、パチンコ球一個が通過可能な広さの通路を球出口としてプレート８ｆ，８ｒの中央に配置したもので、下端に通過スイッチ１１を一個装着し、プレート８ｆ，８ｒから通過スイッチ１１に向けて漏斗状に誘導部１４を設けてなる。
【０００９】
球通路９の中間に位置する球切り通路９ｂには球制御用回転体１２が設けられている。球制御用回転体１２は、丸棒状の胴部１２ａの外周に二組の爪車Ｒ１，Ｒ２を突設してなり、各爪車Ｒ１，Ｒ２が二列の入口通路９ａに対応する。この二組の爪車Ｒ１，Ｒ２は、夫々三枚の係合爪１２ｂ，１２ｂ，１２ｂで構成されている。各爪車Ｒ１，Ｒ２は、図４のように、互いの係合爪１２ｂ，１２ｂ…の角度が６０度づつずれるように設定されており、一方の爪車Ｒ１の係合爪１２ｂがＹ字状態であると、他方の爪車Ｒ２の係合爪１２ｂが逆Ｙ字状態になる。従って、パチンコ球を供給した初期状態では、一方の爪車Ｒ１が図３のように係合爪１２ｂ，１２ｂの背と腹の間でパチンコ球Ｂ１を受け、もう一方の爪車Ｒ２が図４のように係合爪１２ｂ頂部の後述する球止め部１２ｃでパチンコ球を受け止める。
【００１０】
各係合爪１２ｂ，１２ｂ…は、パチンコ球の押出側（腹側）を、その球面がフィットする凹弧形に、また、反対の背側を凸弧形にした形態で、さらに、頂部に爪車Ｒ１，Ｒ２の回転中心を中心とする円弧状の球止め部１２ｃを設けてなり、その高さをパチンコ球より低く設定してなる。
【００１１】
球制御用回転体１２は、図２〜図４のように入口通路９ａの中心直下に配置されている。球制御用回転体１２の胴部１２ａは、プレート８ｆに設置されたステッピングモーター１３の回転軸１３ａに固着されており、該ステッピングモーター１３の駆動によって球制御用回転体１２が図３，図４において反時計回りに回転する。
【００１２】
次にパチンコ球放出装置４の放出動作について、先ず、球制御用回転体１２のプレート８ｒ側の爪車Ｒ１から説明する。図３の実線で示すように、爪車Ｒ１がＹ字状に停止している状態では、上の二枚の係合爪１２ｂ，１２ｂの背と腹の間にパチンコ球Ｂ１が止まり、このパチンコ球Ｂ１の重心が回転軸１３ａの中心を通る直線上にあるため球圧が球制御用回転体１２の回転中心に向かって作用する。
【００１３】
この状態でステッピングモーター１３を作動させて球制御用回転体１２を図３において反時計回りに６０度回転させると、図３一点鎖線のようにパチンコ球Ｂ１が係合爪１２ｂの背に載ったまま球切り通路９ｂの途中で止まる。このとき、パチンコ球Ｂ１の上にあったパチンコ球Ｂ２は図３一点鎖線のように係合爪１２ｂの球止め部１２ｃ上で受け止められている。この状態でパチンコ球Ｂ２を含む上のパチンコ球の球圧が球止め部１２ｃに加わるが、球止め部１２ｃが爪車Ｒ１の回転中心を中心とする円弧形状であるため、前記球圧は回転軸１３ａの中心に向かう。従って、パチンコ球の球圧は球制御用回転体１２の回転に対して殆ど抵抗にならない。
【００１４】
そして、図３一点鎖線の状態からさらに球制御用回転体１２を６０度回転させると、パチンコ球Ｂ１が球切り通路９ｂから抜け、誘導部１４で案内されて排出通路９ｃの中央の球出口に落下し、続いて通過スイッチ１１で検出されてパチンコ球排出樋５に放出される。このとき、パチンコ球Ｂ１の上にあったパチンコ球Ｂ２は係合爪１２ｂと係合爪１２ｂの間で受けられて待機している。
【００１５】
次に、上記したようにプレート８ｒ側の爪車Ｒ１が図３実線のＹ字状態にあるとき、プレート８ｆ側の爪車Ｒ２は図４に示すように逆Ｙ字状態になっていて、パチンコ球Ｂ３を係合爪１２ｂの球止め部１２ｃで受け止めている。そして、球制御用回転体１２が６０度回転すると爪車Ｒ２がＹ字状態になり、上の２つの係合爪１２ｂ，１２ｂの背と腹の間でパチンコ球Ｂ３を保持して次の回転を待つ。次に、球制御用回転体１２が６０度回転すると前記爪車Ｒ１と同様にパチンコ球Ｂ３が球切り通路９ｂで待機し、さらに球制御用回転体１２が６０度回転すると排出通路９ｃに放出される。
【００１６】
以後、球制御用回転体１２が６０度回転する毎に各爪車Ｒ１，Ｒ２から交互に一個づつパチンコ球が放出されるから、例えば、通常の１５個用の入賞信号に対しては球制御用回転体１２を（２＋１／２）回転させればよい。同様に７個用の入賞信号に対しては球制御用回転体１２を（１＋１／６）回転させ、また、図５に示したような球貸装置１８から２５個の球貸命令を受けた場合は球制御用回転体１２を（４＋１／６）回転させればよい。
【００１７】
なお、図示した実施例のように爪車Ｒ１，Ｒ２を偶数組設け、係合爪１２ｂ，１２ｂの背と腹でパチンコ球を受けるＹ字状態と、係合爪１２ｂの球止め部１２ｃでパチンコ球を受ける逆Ｙ字状態を交互に繰り返す設定にしておけば、球制御用回転体１２の停止位置が常に自動的に補正される。すなわち、爪車Ｒ１（Ｒ２）は図３実線のようにＹ字状態にあって係合爪１２ｂ，１２ｂの背と腹の間の窪みで球圧を受けているとき最も安定する。一方、そのとき他方の爪車Ｒ２（Ｒ１）は、係合爪１２ｂの球止め部１２ｃでパチンコ球を受け止めている状態であるから球圧の抵抗を殆ど受けずに軽い力でも回転し得る。従って、もし球制御用回転体１２の停止位置が一定にならなくとも、Ｙ字状態側の爪車Ｒ１，Ｒ２が球圧の作用で安定した位置に戻されるため、球制御用回転体１２の停止位置が常に自動的に補正されるのである。
【００１８】
【発明の効果】
本発明のパチンコ球放出装置は、複数列に分かれているパチンコ球導出樋にそのまま接続することができ、しかも一個単位で放出することができる。その上、放出球の検出構造がスイッチ一個でよいため低コストになる効果がある。

[0007]
Further, the mechanism board 1 further includes a winning ball set 集める 6 that collects winning pachinko balls (winning balls), and a winning ball processing device 7 that processes the winning balls of the winning ball set 樋 6 one by one and generates a winning signal. Is provided.
[0008]
As described above, the pachinko ball discharge device 4 is interposed between the pachinko ball lead-out rod 3 and the pachinko ball discharge rod 5, and both balls 3, 3 are formed by the ball passage 9 formed between the two plates 8 f and 8 r. Tie five. The spherical passage 9 is divided into an upstream inlet passage 9a, an intermediate spherical cutting passage 9b, and a downstream discharge passage 9c. The entrance passage 9a has a double-row structure divided into two rows via a central partition plate 9d, and has proximity switches 10 and 10 for detecting pachinko balls on the side surface. On the other hand, the discharge passage 9c on the downstream side has a single-row structure without a partition, and as shown in FIG. 2, a passage having a width through which one pachinko ball can pass is used as a ball outlet in the center of the plates 8f and 8r. One passing switch 11 is mounted at the lower end, and a guiding portion 14 is provided in a funnel shape from the plates 8f and 8r toward the passing switch 11.
[0009]
Sphere control rotor 12 is provided in the ball cutting path 9b is located between the ball passage 9. The ball control rotator 12 is formed by projecting two sets of claw wheels R1 and R2 on the outer periphery of a round bar-shaped body 12a, and each claw wheel R1 and R2 corresponds to two rows of inlet passages 9a. The two sets of claw wheels R1 and R2 are each composed of three engagement claws 12b, 12b and 12b. As shown in FIG. 4, each claw wheel R1, R2 is set so that the angles of the engagement claws 12b, 12b... Are shifted by 60 degrees, and the engagement claw 12b of one claw wheel R1 is Y-shaped. In this state, the engaging claw 12b of the other claw wheel R2 is in an inverted Y-shape. Therefore, in the initial state in which the pachinko balls are supplied, one pawl wheel R1 receives the pachinko ball B1 between the back and the abdomen of the engaging claws 12b and 12b as shown in FIG. 3, and the other pawl wheel R2 is shown in FIG. Thus, the pachinko ball is received by a ball stopper 12c described later on the top of the engaging claw 12b.
[0010]
Each of the engaging claws 12b, 12b... Has a concave arc shape that fits the spherical surface of the push-out side (abdominal side) of the pachinko sphere, and a convex arc shape on the opposite back side. An arc-shaped ball stopper 12c centering on the rotation center of the claw wheels R1, R2 is provided, and the height thereof is set lower than that of the pachinko ball.
[0011]
As shown in FIGS. 2 to 4, the ball control rotator 12 is disposed immediately below the center of the inlet passage 9 a. The body 12a of the ball control rotator 12 is fixed to a rotating shaft 13a of a stepping motor 13 installed on the plate 8f, and the sphere control rotator 12 is driven by the stepping motor 13 as shown in FIGS. Rotate counterclockwise at.
[0012]
Next, the discharge operation of the pachinko ball discharge device 4 will be described first from the claw wheel R1 on the plate 8r side of the ball control rotor 12. As shown by the solid line in FIG. 3, in a state where the claw wheel R1 is stopped in a Y shape, the pachinko ball B1 stops between the back and the abdomen of the upper two engaging claws 12b and 12b, and this pachinko ball Since the center of gravity of B1 is on a straight line passing through the center of the rotation shaft 13a, the ball pressure acts toward the rotation center of the ball control rotating body 12.
[0013]
In this state, when the stepping motor 13 is operated and the ball control rotating body 12 is rotated 60 degrees counterclockwise in FIG. 3, the pachinko ball B1 is placed on the back of the engaging claw 12b as shown in FIG. It stops in the middle of the ball cutting passage 9b. At this time, the pachinko sphere B2 on the pachinko sphere B1 is received on the ball stopper 12c of the engaging claw 12b as shown by a one-dot chain line in FIG. In this state, the ball pressure of the upper pachinko sphere including the pachinko ball B2 is applied to the ball stopper 12c. However, since the ball stopper 12c has an arc shape centered on the rotation center of the claw wheel R1, the ball pressure is rotated. Heading to the center of the shaft 13a. Accordingly, the ball pressure of the pachinko sphere is hardly resistant to the rotation of the ball control rotor 12.
[0014]
Then, when the ball control rotator 12 is further rotated 60 degrees from the state of the one-dot chain line in FIG. 3, the pachinko ball B1 comes out of the ball cutting passage 9b and is guided by the guide portion 14 to the central ball outlet of the discharge passage 9c. Then, it is detected by the passing switch 11 and discharged to the pachinko ball discharge basket 5. At this time, the pachinko ball B2 on the pachinko ball B1 is received between the engaging claw 12b and the engaging claw 12b and is waiting.
[0015]
Next, as described above, when the pawl wheel R1 on the plate 8r side is in the Y-shape in FIG. 3, the pawl wheel R2 on the plate 8f side is in the inverted Y-shape as shown in FIG. The ball B3 is received by the ball stopper 12c of the engaging claw 12b. When the ball control rotator 12 rotates 60 degrees, the ratchet wheel R2 becomes Y-shaped, and the pachinko ball B3 is held between the back and the abdomen of the upper two engaging claws 12b and 12b to perform the next rotation. wait. Next, when the ball control rotator 12 rotates 60 degrees, the pachinko ball B3 waits in the ball cutting passage 9b as in the case of the ratchet wheel R1, and when the sphere control rotator 12 rotates 60 degrees, it is discharged into the discharge passage 9c. Is done.
[0016]
Thereafter, every time the ball control rotator 12 rotates 60 degrees, pachinko balls are released one by one from each of the ratchet wheels R1 and R2, so that, for example, the ball control is performed for the normal 15 winning signals. The rotating body 12 may be rotated (2 + 1/2). Similarly, for the seven winning signals, the ball control rotating body 12 is rotated (1 + 1/6), and 25 ball lending commands are received from the ball lending apparatus 18 as shown in FIG. In this case, the sphere control rotator 12 may be rotated (4 + 1/6).
[0017]
As shown in the illustrated embodiment, an even number of sets of claw wheels R1 and R2 are provided, a Y-shaped state for receiving pachinko balls at the back and abdomen of the engaging claws 12b and 12b, and pachinko balls at the ball stoppers 12c of the engaging claws 12b. If the reverse Y-shaped state for receiving is set to repeat alternately, the stop position of the ball control rotating body 12 is always automatically corrected. That is, the ratchet wheel R1 (R2) is most stable when it is in the Y-shape as shown by the solid line in FIG. 3 and is subjected to the ball pressure in the recess between the back and the abdomen of the engaging claws 12b and 12b. On the other hand, at this time, the other ratchet wheel R2 (R1) is in a state in which the pachinko ball is received by the ball stopper 12c of the engaging claw 12b, so that it can rotate even with a light force without receiving any resistance of the ball pressure. Therefore, even if the stop position of the ball control rotating body 12 is not constant, the Y-shaped side wheel R1, R2 is returned to a stable position by the action of the ball pressure. The stop position is always automatically corrected.
[0018]
【The invention's effect】
The pachinko sphere discharge device of the present invention can be connected as it is to the pachinko sphere outlets divided into a plurality of rows, and can be discharged in units of one. In addition, since the detection structure of the emitted sphere is only one switch, the cost can be reduced.
