- the command analysis circuit 3 sets, for each signal line COMy, a pulse in which an LED connected to the signal line can be energized alternately at a constant period, and a period in which the pulse is applied for each signal line COMy. A signal having a first potential and a second potential different from the first potential is generated for a period in which no pulse is applied.

- the setting circuit 5 receives a setting signal for instructing a setting common to each signal line from the effect CPU, and adjusts a signal output from each signal line according to the setting signal. For example, the setting circuit 5 inverts the signal value output from the command analysis circuit 3 to the gradation control circuit 7 when receiving the inversion signal INV that is one of the setting signals from the effect CPU. That is, during a period in which a signal having the first potential is output from the command analysis circuit 3 to a certain signal line SEGx, the gradation control circuit 7 cannot energize the LED connected to the signal line SEGx. On the other hand, during a period in which a signal having the second potential is output from the command analysis circuit 3, the gradation control circuit 7 can energize the LED connected to the signal line SEGx.

Further, for example, when the gaming machine equipped with the light source control device 1 is in a standby state, the light source control device 1 uses the brightness adjustment signal ADJ to uniformly reduce the light emission intensity of all the LEDs. The power consumption of the gaming machine can be suppressed.
- the dynamic control circuit 6 is connected to each signal line COMy, and has a switching element (not shown) such as a transistor for each signal line. For example, for each signal line COMy, a signal for the signal line received from the command analysis circuit 3 is input to the switching element. Then, while the signal has the first potential, the switching element conducts the corresponding signal line COMy to a power source (not shown), while if the signal has the second potential, the corresponding signal line COMy.

Abstract
Description
そこで、配線の量及び演出用のプロセッサユニットの端子の数を減らすために、演出用のプロセッサユニットと各LEDとの間に設置され、LEDの発光強度及び発光タイミングを制御する光源制御装置が遊技機に搭載されることがある。
また、特開2006-218137号公報には、ドライバICを有する発光体の駆動システムが開示されており、このドライバICは、コントローラから、それぞれシリアルデータ線及びクロックデータ線がカスケード接続され、それぞれコントローラからのシリアル信号とパラレル信号とを変換する変換回路と、発光体を動作させる駆動回路とを有する。
しかし、上記のように、遊技機には数百個のLEDが搭載されることがあるので、全てのLEDを制御するためには、10個またはそれ以上の光源制御装置が必要となることがあった。このように多数の光源制御装置が使用されると、遊技機全体のコストが高くなってしまう。また、演算用のプロセッサユニットは多数の光源制御装置を制御しなければならないので、そのプロセッサユニットの制御負荷が大きいという問題があった。
この遊技機において、複数の光源のそれぞれのアノードは、複数の第1の信号線の何れかと接続され、カソードが複数の第2の信号線の何れかと接続され、かつ、接続される第1の信号線と第2の信号線の組が光源ごとに異なる。
また演出制御部は、遊技の状態に応じて、複数の光源のうちの一つの発光量を複数のビットにより規定する階調データを複数の光源のそれぞれごとに含む制御コマンドを生成し、その制御コマンドを光源制御装置へシリアル伝送する。
そして光源制御装置は、その制御コマンドを受信するインターフェース部と、複数の第1の信号線のそれぞれに対して、一定周期で交互に、複数の光源のうちのその第1の信号線に接続された光源を通電可能とする第1の期間を設定する第1の信号を生成し、かつ、複数の第2の信号線のそれぞれに対して、複数の光源のうちのその第2の信号線に接続された光源のアノードが接続された第1の信号線に対して、第1の期間が設定されている間に、制御コマンドに含まれたその光源に対応する階調データに表された発光量に応じて、その光源を通電可能とする第2の期間を設定する第2の信号を生成するコマンド解析部と、複数の第1の信号線のそれぞれに対して、第1の信号において設定された第1の期間の電位が第1の期間以外の電位よりも高くなるように電圧を印加するダイナミック制御部と、複数の第2の信号線のそれぞれに対して、第2の信号において設定された第2の期間中、複数の光源のうちのその第2の信号線に接続された光源を通電可能とする階調制御部とを有する。
また、LED10-1、10-5、10-9、10-13のカソードは、信号線SEGAに接続されている。同様に、LED10-2、10-6、10-10、10-14のカソードは、信号線SEGBに接続されている。さらに、LED10-3、10-7、10-11、10-15のカソードは、信号線SEGCに接続されている。そしてLED10-4、10-8、10-12、10-16のカソードは、信号線SEGDに接続されている。
各信号線COM1~COM4、SEGA~SEGD及びDISCは、それぞれ、後述する本発明の一つの実施形態による光源制御装置と接続される。
したがって、光源制御装置は、信号線COM1~COM4及びSEGA~SEGDの電位を調整することで、LED10-1~10-16のうちの任意のLEDを点灯させることができる。
また、LEDのカソードに接続される信号線SEGxの数も4本でなくてもよい。
光源制御装置1が有するこれらの各部は、それぞれ、別個の回路として回路基板(図示せず)上に実装されてもよく、あるいは、これらの各部が集積された集積回路として回路基板上に実装されてもよい。
またインターフェース回路2は、演出用CPUから、制御コマンドが制御対象とする光源制御装置を特定するための識別信号を受信する。そしてインターフェース回路2は、制御コマンド、クロック信号及び識別信号をコマンド解析回路3へ渡す。
またインターフェース回路2は、複数の光源制御装置1がカスケード接続されている場合に、受け取った制御コマンド及びクロック信号を次の段の他の光源制御装置へ転送する。
なお、制御コマンドの詳細については後述する。
デバイスアドレス302は、制御コマンド300が制御対象とする光源制御装置を特定するための識別情報であり、本実施形態では、7ビット長のビット列で表される。デバイスアドレス302は、上述したように、コマンド解析回路3により、識別信号ADRと一致するか否か判定され、一致する場合、光源制御装置1が、制御コマンド300の制御対象であると判定される。
制御データ303は、さらに、制御コマンドに含まれる階調データ304の数を規定する階調データ数を含んでいてもよい。これにより、光源制御装置1が同時に制御可能な最大LED数よりも少ない数のLEDが光源制御装置1に接続されている場合、制御コマンドを短縮できる。
なお、各階調データ304の先頭からの順序は、他のLEDの配列と対応していてもよい。
コマンド解析回路3は、デバイスアドレスが識別情報ADRと一致しなければ制御コマンドを廃棄する。一方、デバイスアドレスが識別情報ADRと一致すれば、コマンド解析回路3は、制御コマンドのフォーマットに従って、制御コマンドから制御データを抽出し、その制御データに含まれる階調制御ビットを参照して、各階調データのビット長を確認する。そしてコマンド解析回路3は、制御コマンドのうちの階調データが格納された部分を階調制御ビットに規定されたビット数で区切ることにより、各階調データを抽出し、その階調データをレジスタ4に記憶させる。
図4において、波形401~404は、それぞれ、信号線COM1~COM4に印加される信号波形を表し、波形405~408は、それぞれ、信号線SEGA~SEGDに印加される信号波形を表す。各信号波形に対する横軸は時間を表す。また、縦軸は信号線に印加される電位を表し、Hは高電位を、Lは低電位をそれぞれ表す。
信号波形401~404に示されるように、各信号線COM1~COM4に対しては、何れか一つの信号線にのみ、高電位を持つパルスがCOM1からCOM4へ順に、交互に印加される。そしてそのパルス幅は、例えば、1msecである。したがって、この場合、4msecを一周期として、信号線COM1~COM4の何れにも、各周期中に一度、パルスが印加される。
波形501、502に示されるように、時刻t1にて信号線COM1に印加されたパルスが印加された期間が終了し、信号線COM2に対してパルスが印加される期間が開始する。しかし、波形500に示されるように、P点では、残留電荷により、時刻t1を経過した後も、電位は直ぐには低下せず、残留電荷が放出されるにつれて徐々に低下する。ここで、信号線COM2とSEGAに接続されたLED10-5を点灯させるべく、時刻t1の直後に信号線SEGAの電位が下げられると、信号線COM1の電位と信号線SEGA間の電圧がLED10-1が点灯する最小電圧よりも大きくなり、その結果として、時刻t1の直後から信号線COM1の残留電荷が十分に放出されるまでの期間、LED10-1も誤点灯することになる。
図6において、波形601~604は、それぞれ、信号線COM1~COM4に印加される信号波形を表す。また波形605は、放電用信号線DISCが通電可能な期間と通電不能な期間の時間変化を表す。そして波形606~609は、それぞれ、信号線SEGA~SEGDに印加される信号波形を表す。各信号波形601~604、606~609に対する横軸は時間を表す。また、縦軸は信号線に印加される電位を表し、Hは高電位を、Lは低電位をそれぞれ表す。さらに、波形605に対して、横軸は時間を表し、縦軸の'可'は通電可能であることを表し、'不'は通電不能であることを表す。
なお、放電期間は、LEDが誤点灯しない程度に信号線COMyの残留電荷が放電される期間の最小値、例えば、20μsecに設定される。
また、制御コマンドの制御データに、放電期間を設定するか否かを表す放電設定フラグを含めてもよい。この場合、コマンド解析回路3は、その放電設定フラグの値を参照することにより、放電期間を設定するか否かを切り替えてもよい。例えば、放電設定フラグが、放電期間を設定することを表す値(例えば、'1')に設定されていれば、コマンド解析回路3は、図6に示されるように、各信号線COMyに印加されるパルスの立ち上がりと同時に開始される放電期間を設定し、その放電期間中、放電用信号線DISCを通電可能とする。
一方、放電設定フラグが、放電期間を設定しないことを表す値(例えば、'0')に設定されていれば、コマンド解析回路3は、図4に示されるように、放電期間を設定せずに、各信号線に対する信号波形を決定する。
またコマンド解析回路3は、各信号線SEGxについて、LED10-1~10-16のうちのその信号線に接続されたLEDのアノードが接続された信号線COMyに対してパルスが印加される期間内に、制御コマンドに含まれたそのLEDに対応する階調データに表された発光量に応じて、そのLEDを通電可能とする期間を設定する。そしてコマンド解析回路3は、各信号線SEGx及び放電用信号線DISCのそれぞれについて、通電可能となる期間中、第1の電位を持ち、通電不能となる期間に対してその第1の電位と異なる第2の電位を持つ信号を生成する。そしてコマンド解析回路3は、各信号線SEGx及び放電用信号線DISCに対応する信号を、設定回路5を介してパラレルに階調制御回路7へ出力する。
そしてコマンド解析回路3は、新たな制御コマンドを受信するまで、レジスタ4に記憶された階調データに従って、各LEDの発光量を特定する。したがって、光源制御装置1により制御される各LEDの発光パターンは、光源制御装置1が新たな制御コマンドを受信するまで、前回の制御コマンドに規定された発光パターンのまま維持される。
また、設定回路の機能は、コマンド解析回路が有するプロセッサが実行してもよい。この場合には、コマンド解析回路は、各信号線COMy、SEGx及びDISCへの信号を、演出用CPUから受け取った設定信号に基づいて修正した後に、ダイナミック制御回路及び階調制御回路へ出力する。
なお、さらに他の変形例では、定電流回路8は、各信号線COMyとダイナミック制御回路6との間に接続される可変抵抗器を有してもよい。この場合も、各可変抵抗器の抵抗値が、設定回路5が受信した輝度調整信号ADJに規定された比率だけ、各LEDの発光輝度が低下するように調節されることで、光源制御装置は、各LEDの発光量を一律に調整できる。
図8は、上記の実施形態またはその変形例による光源制御装置を備えた弾球遊技機100の概略斜視図である。また図9は、弾球遊技機100の概略背面図である。図8に示すように、弾球遊技機100は、上部から中央部の大部分の領域に設けられ、遊技機本体である遊技盤101と、遊技盤101の下方に配設された球受け部102と、ハンドルを備えた操作部103と、遊技盤101の略中央に設けられた表示装置104と、遊技盤101の前面において表示装置104の周囲及び遊技盤101の下方に配置され、遊技の演出に用いられる役物部105とを有する。また遊技盤101の側方にはレール106が配設されている。また遊技盤101上には多数の障害釘(図示せず)及び少なくとも一つの入賞装置107が設けられている。
そして光源制御装置112は、制御コマンド及び輝度調整信号ADJに従って、各LEDを所定の発光強度で明滅させる。
