Description
[回路構成]
図1は、記録装置の制御回路の主要構成の例を示すブロック図である。図1において、電源回路101は、電源部として動作し、AC電源から記録ヘッド3を駆動するためのDC電圧を提供する。電源回路101において、記録ヘッド3に供給されるヘッド電源に用いられるDC電圧の出力をVMと表記する。
図1〜図3を用いて、ヘッド電源の制御シーケンスを説明する。図2は、記録装置が印刷指令を受け取り、記録ヘッド3に電源電圧が印加されていない状態から記録ヘッド3に電源を投入して印刷動作を行う際の流れを示す。図3は、図2の制御に伴うタイミングチャートを示す。図3(a)の縦軸は電解コンデンサの電圧[V]を示し、横軸は時間の経過を示す。図3(b)の縦軸は電流値[A]を示し、横軸は時間の経過を示す。なお、図3(b)では、縦軸において、原点から上を充電電流とし、原点から下を放電電流として示す。図3(c)の縦軸はヘッド電源制御ブロック102の出力端子PO1の電圧レベルを示し、横軸は時間の経過を示す。なお、図3(a)〜図3(c)の時間の経過のタイミングは対応しているものとする。
ここで、本実施形態に係るCPU123の動きについて説明する。CPU123は、印刷動作に関する制御全体の管理とヘッド電源が正常に動作していることを管理する。以下に詳細を示す。
ヘッド電源制御ブロック102について説明する。図4は、ヘッド電源制御シーケンサ122内の状態遷移を説明するための図である。図4(a)では、ヘッド電源がオフされている状態をスタンバイ401としている。印刷ジョブが投入されると、ヘッドの電源をオンにするために、状態は充電402に遷移する。充電402における電流値の切り替えは図4(b)に示される様に、電解コンデンサ105の電圧値がVth1を超えると、402_1の充電1から充電2に遷移する。その際、上述したように、充電電流の値は、Ichg1からIchg2に切り替えられる。同様に、402_2の充電2から402_3の充電3に遷移すると、充電電流の値は、Ichg2からIchg3に切り替えられる。充電が完了すると、図4(a)の保持403の状態に移行する。これに伴い充電電流の値はIkeepに切り替えられる。なお、印刷動作を急ぐ場合には印刷動作404の状態に直接遷移しても構わない。
