Description

【0001】
【発明の属する技術分野】
本発明は、複写機、プリンタ、ファックス等の複数の機能を有する電子写真方式のデジタル複合機に関し、特に省エネ技術に関するものである。
【0002】
【従来の技術】
複写機のデジタル化によって本来のコピー機能のほかに複写機のリソース(スキャナや電子写真プロッタ)を使い、通信機能を組み合わせてFAX機能やプリンタ機能を併せ持つデジタル複合機が登場してきた。FAX機能は機器が省電力状態においても着信を監視し、機器を復帰させるため回線通信部などの一部回路を通電している。
また、プリンタ機能においては、プリント要求で機器を復帰させるためI/F回路などの一部回路を通電している。さらに、コピー機能においても圧板開閉などのコピーを取ろうとする行為をいち早く検知し、機器を素早く復帰させるために圧板開閉検知回路のなど一部の回路に通電している。
【0003】
【発明が解決しようとする課題】
省電力からの復帰は多くのユーザーにとっては便利なものとなるが、復帰要因を検知するため省電力時の消費電力が増えることになる。また、ユーザーの業務形態、機器の使用状況などの条件により、上述した機器の省電力からの立ち上がり検知はすべての場合に必要とは限らない。むしろ、電力を浪費しないことが望まれるケースもある。
例えば、FAX受信の使用頻度は高いので復帰要因として必要だが、プリンタ使用頻度は低いので、使いたい時に操作にて機器を立ち上げる使い方をし、省電力時の電力をさらに低くしたい場合がある。またコピー機能は手動で、省電力時の電力を押さえたい場合もある。
そこで本発明は、省電力時においてユーザーが所望しない復帰要因の回路に供給する電力を遮断することで、ユーザーの使用形態に応じたさらなる省電力を図ることが可能なデジタル複合機を提供することを目的する。
【0004】
【課題を解決するための手段】
上記目的を達成するために、請求項1記載の発明は、一部の回路のみ通電されている省電力状態から複数の復帰要因によって機器すべてに通電し起動するデジタル複合機において、前記復帰要因を検知する復帰要因検知手段別に設けられた電力遮断手段と、前記復帰要因検知手段別に関連付けられた電力供給禁止情報を記憶する記憶手段と、前記電力供給禁止情報の入力手段と、前記電力供給禁止情報により省電力時の復帰要因検知手段の電力を遮断する制御を行なうメイン制御手段と、を備えたことを特徴とする。
請求項2記載の発明は、請求項1記載のデジタル複合機において、復帰要因検知手段は、FAX受信検知部、プリント要求検知部、及び圧板開閉検知部であることを特徴とする。
【0005】
【発明の実施の形態】
以下、図面により本発明の実施の形態を詳細に説明する。図1は本発明の実施の形態に係るデジタル複合機の機能ブロック図である。図1において、操作部1は、操作キーおよび表示素子で構成される。この操作部1によりオペレータは動作モードの指定やデータの入力を行うことができる。さらに本例ではオペレータの押下操作により機器を省電力状態に移行させるためと、省電力状態から復帰させるための節電キー1−1を備えている。
スキャナ部2は、光源、CCD等の固体撮像素子及びメカ機構等で構成され、読み取った画像を電気変換し画像信号にする。プロッタ部3は、電子写真方式を採用しておりスキャナ部2から送られてくる画像信号やFAX受信画像、プリンタ展開画像などの画像信号を転写紙に画像形成する。
【0006】
メイン制御部4は、前述の操作部1、スキャナ部2、プロッタ部3の動作を制御する(また、本例では詳細を述べないが画像処理、画像メモリを有し、ソフトウェアによってFAX機能、プリンタ機能も実現している)。メイン制御部4はOFF信号0〜3を通じて遮断機21―1〜21−4をOFFできる構成となっている。
本発明では、省電力時に電力供給をOFFするユニット(スキャナ部2、プロッタ部3)と、省電力時の復帰要因を検知する復帰要因検知回路(復帰要因検知手段)別に遮断機21が設けられており、これらをメイン制御部4で制御することで機器は省電力状態となる。但し、メイン制御部4には省電力状態であっても電力が供給される構成となっているので、省電力状態からの復帰要因を監視できる。メイン制御部4の詳細は図2を用いて後述する。
FAX受信検知部5は、復帰要因検知回路の一つである。機器が省電力状態であり回路に電力が供給されている時は、FAX受信時に復帰要因信号1をメイン制御部4に送る。
プリント要求検知部(プリンタデータ受信検知部)6は、復帰要因検知回路の一つである。機器が省電力状態であり回路に電力が供給されている時は、プリント要求の受信時に、プリント要求による復帰要因信号2をメイン制御部4に送る。
圧板開閉検知部7は、機器が省電力状態で回路に電力が供給されているとき、圧板開閉を検知し、復帰要因信号3をメイン制御部4に送る。PSU8は、商用電源を各部に供給する。
【0007】
図2は図1に示すメイン制御部の詳細ブロック図である。図2において、CPU11は、本実施形態のデジタル複合機の制御を実際に行う素子である。ROM12は、デジタル複合機全体を制御するプログラムおよび制御に必要なデータが格納されている。RAM13は、CPU11が制御上データや状態を一時的に記憶するために使用される。
不揮発性メモリ14は、メイン制御部4の電源がOFFしてもデータを保持することができ、本実施例はバッテリーバックアップされた不揮発RAMを使用している。不揮発性メモリ(不揮発RAM)14は、ユーザー入力の設定データなどの記憶に用い、復帰要因検知回路の電力供給禁止情報も記憶している。
I/Oポート15を介してCPU11は、制御対象の駆動やセンサ信号の検知を行い、操作部1、スキャナ部2、プロッタ部3の制御を行う。さらにOFF信号0〜3の出力および復帰要因信号1〜3の検知を行う。
その他、本例では図示していないが、メイン制御部4中に画像処理部、画像メモリを備えており、コピー画像処理や、FAX送受信画像・プリンタ受信データの蓄積・展開などの処理を行う。
また、復帰要因検知回路に電力供給する、また電力供給しないの設定は操作部1を通じてオペレータが行い、設定内容を不揮発性メモリ14に記憶する。図4に設定画面例を示す。図4はFAX受信の復帰は望むがプリント要求および圧板開閉は復帰要因として望まない例である。
【0008】
続いて本発明の動作説明を行う。図3は本発明のデジタル複合機の省電力処理フローチャートである。ユーザーの節電キー1−1の押下や、一定時間操作されない場合などの条件で機器は省電力処理に移行する。はじめにOFF信号0を制御し遮断器0で電源を切り離すことで、スキャナ部2、プロッタ部3の電力をOFFとする(S1)。続いて、メイン制御部4の不揮発性RAM14で記憶している復帰要因検知回路の電力供給禁止情報を確認し、FAX受信検知部5の電力供給が禁止されていれば(S2でY)、OFF信号1をOFFとし(S3)、FAX受信検知部5の電力供給を停止する。
電力供給が禁止されていなければ(S2でN)OFF信号1をONとし(S4)、受信データが無いか確認し(S5)、もし受信データがあれば省電力状態から復帰する(S6)。プリント要求検知部6および圧板開閉検知部7についてもFAX受信検知と同様の処理がなされる(S7〜S14)。さらに、節電キー1−1が押され(S15でY)、オペレータが省電力状態の解除を指示してないか確認する。以上の動作を復帰要因が検知できるまで続けることとなる。
上記説明した省電力処理を行うことで、不揮発RAM14が記憶している復帰要因検知回路の電力供給禁止情報によって、復帰要因検知回路の電源を遮断することができるので遮断数に応じたさらなる省電力が可能となる。また、復帰要因の必要に応じて電力供給を許可すれば、操作性が向上した機器として使用することも可能となる。
【0009】
【発明の効果】
以上説明したように、本発明によれば、省電力状態からの復帰要因を検知する復帰要因検知手段別に電力遮断手段を備え、ユーザーにより入力可能な禁止情報により、省電力時の復帰要因検知手段の電力を供給するか否かを設定できるので、ユーザーの使用形態に応じたさらなる省電力のデジタル複合機を提供できる。

If there is received data, the process returns from the power saving state (S6). The print request detection unit 6 and the pressure plate open / close detection unit 7 perform the same processing as the FAX reception detection (S7 to S14). Further, it is confirmed whether the power saving key 1-1 has been pressed (Y in S15) and the operator has not issued an instruction to cancel the power saving state. The above operation is continued until the return factor can be detected.
By performing the above-described power saving processing, the power supply of the return factor detection circuit can be shut off based on the power supply prohibition information of the return factor detection circuit stored in the nonvolatile RAM 14, so that further power saving according to the number of cutoffs Becomes possible. If power supply is permitted according to the need for a return factor, the device can be used as a device with improved operability.
