【発明の実施の形態】
次に本発明の実施例のについて、図面を参照して、詳細に説明する。図１は本実施例の回路構成を示すブロック図、図２および図３は本実施例を折り畳み型携帯電話機において実現した場合の外観図であり、図２は携帯電話機を閉じた状態、図３は携帯電話機を開いた状態を示す図である。
【００１３】
図１によれば、本実施例の回路構成は、携帯電話機の主電源である電池３と、電池３の電圧値をＡ／Ｄ変換するＡ／Ｄコンバータ２と、本実施例の回路動作を制御するＬＥＤ制御部１と、電池３の残量を区別して点灯するＬＥＤ４、５、６と、電池３の残量確認を行うためのキー７と、残量確認を行うためのキー７の操作と連動して電池充電の一時停止を制御する充電制御部８とその制御信号（Ｓｉｇ１／Ｓｉｇ２）により構成されている。
【００１４】
Ａ／Ｄコンバータ２は、携帯電話機の主電源である電池３の電圧値をＡ／Ｄ変換し、ＬＥＤ制御部１に入力する。ＬＥＤ制御部１には電池残量に応じて数段階の電池レベルが設定されており、 ＬＥＤ制御部１は、Ａ／Ｄコンバータ２から入力されるＡ／Ｄ変換値により電池レベルを監視し、電池レベルの変化有無を判断する。本実施例では、電池レベルは、３段階に設定してあるものとし、電池残量が３分の２以上の状態を「電池レベル３」、３分の１から３分の２の状態を「電池レベル２」、３分の１以下の状態を「電池レベル１」とする。また、充電制御部８は電池３の充電制御を行うとともに、常時ＬＥＤ制御部１に対して充電中または非充電中の状態報告（Ｓｉｇ２）を行っている。なお、充電時においては、Ａ／Ｄコンバータ２への入力は充電電圧印可された状態の電池電圧となるため、ＬＥＤ制御部１は電池残量に関わらず「充電中」と判断する。
【００１５】
ＬＥＤ４、ＬＥＤ５、ＬＥＤ６はそれぞれ発光色の異なるＬＥＤであり、携帯電話機の着信時の表示や充電中か否かの状態表示を目的として設置されており、本発明での電池残量表示をする場合には、ＬＥＤ制御部１の制御により、例えば電池レベル１に対してはＬＥＤ４、電池レベル２に対してはＬＥＤ５、電池レベル３に対してはＬＥＤ６が選択される。図２の外観図に示すように、折り畳んだ状態においても目視確認できるよう、ＬＥＤ４、５、６は背面より発光する構造となっている。
【００１６】
電話番号や電池残量等の各種情報の表示を行う表示部１０、および通話時や待ち受け時の各種操作を行うキー９については、図３の外観図に示すように、いずれも携帯電話機を折り畳んだ際に内側となる面に配置されているため、携帯電話機を開いた場合においてのみ目視確認できる。また、キー７は電池レベルの確認を行うためのキーであり、図２に示すように、折り畳んだ状態でも押下可能な位置（ここでは携帯電話機側面）に配置されている。
【００１７】
通常動作時において、ＬＥＤ制御部１は、キー７が押下されたことを検出すると、電池レベルに応じて選択されたＬＥＤを一定時間点灯させる。
【００１８】
一方充電時においては、前述の通りＬＥＤ制御部１は電池残量に関わらず「充電中」と判断し、充電中の状態の表示としてＬＥＤ６を連続点灯している。従って、充電時における電池レベル確認については、ＬＥＤ制御部１はキー７が押下を検出すると、充電制御部８に対して充電停止信号（Ｓｉｇ１）を出力して充電を一旦停止させ、電池レベルの判断結果に応じてＬＥＤの選択切り換えを行い、ＬＥＤを一定時間点灯させる。ＬＥＤの点灯が完了すると、ＬＥＤ制御部１は充電制御部８に対して充電開始信号（Ｓｉｇ２）を出力し充電を再開させる。充電再開後、再度充電中の状態の表示としてＬＥＤ６を連続点灯する。
【００１９】
次に、本実施例の動作について、図面を用いて説明する。図４は通常使用時における、電池レベルに応じたＬＥＤ選択切替フローチャート、図５は選択されたＬＥＤを点灯させるフローチャート、図６は電池の充電時における本実施例の動作を示すフローチャートである。
【００２０】
図４によれば、まずＡ／Ｄコンバータ２が電池３の電圧値をＡ／Ｄ変換し、ＬＥＤ制御部１に入力する（Ｓ１１）。ＬＥＤ制御部１は入力されたＡ／Ｄ変換値により電圧レベルを監視し、電圧レベルの変化有無を判断する（Ｓ１２）。Ｓ１３において、電池レベルが変化した場合、ＬＥＤ制御部１は電池レベルの変化に応じてＬＥＤの選択切り替えを行い（Ｓ１４）、Ｓ１１へ戻る。Ｓ１３において、電池レベルが変化しなかった場合は、ＬＥＤの選択切り替えは行わずにＳ１１へ戻る。
【００２１】
図５によれば、まずＬＥＤ制御部１がキー７押下による電池レベル確認要求の有無を検出する（Ｓ２１）。Ｓ２２において、電池レベル確認要求有りの場合、ＬＥＤ制御部１は電池レベルに応じて選択されている発光色のＬＥＤを一定時間点灯させ（Ｓ２３）、Ｓ２１に戻る。Ｓ２２において、電池レベル確認要求無しの場合は、ＬＥＤの点灯は行わず、再びＳ２１に戻る。
【００２２】
次に、充電時における動作について図６を参照すると、まずＬＥＤ制御部１がキー７押下による電池レベル確認要求の有無を検出する（Ｓ３１）。Ｓ３２において、電池レベル確認要求有りの場合、ＬＥＤ制御部１は充電制御部８に対して充電停止信号（Ｓｉｇ１）を出力し充電を停止させ（Ｓ３３）、充電中を表示するＬＥＤ６を消灯する（Ｓ３４）。充電停止後、Ａ／Ｄコンバータ２は電池３の電圧値をＡ／Ｄ変換し、ＬＥＤ制御部１に入力する（Ｓ３５）。ＬＥＤ制御部１は入力されたＡ／Ｄ変換値により電池レベルを判断し（Ｓ３６）、電池レベルに応じてＬＥＤの選択切り換えを行い（Ｓ３７）、ＬＥＤを一定時間点灯させる（Ｓ３８）。ＬＥＤ点灯完了後、ＬＥＤ制御部１は充電制御部８に対して充電開始信号（Ｓｉｇ２）を出力し充電を再開させ（Ｓ３９）、充電中を表示するＬＥＤ６を再度点灯し（Ｓ４０）、Ｓ３１に戻る。Ｓ３２において、電池レベル確認要求無しの場合は、再びＳ３１に戻る。
【００２３】
次に、本発明の他の実施例について図面を用いて説明する。図７は、本実施例の回路構成を示すブロック図、図８および図９は本実施例を折り畳み型携帯電話機において実現した場合の外観図であり、図８は携帯電話機を折り畳んだ状態、図９は携帯電話機を開いた状態を示す図である。
【００２４】
図７によれば、本実施例の回路構成は、携帯電話機の主電源である電池３と、電池３の電圧値をＡ／Ｄ変換するＡ／Ｄコンバータ２と、本実施例の回路動作を制御するＬＥＤ制御部１と、電池３の残量を区別して点灯するＬＥＤ１１と、電池３の残量確認を行うためのキー７と、残量確認を行うためのキー７の操作と連動して電池充電の一時停止を制御する充電制御部８とその制御信号（Ｓｉｇ１／Ｓｉｇ２）により構成されている。
【００２５】
初めに、Ａ／Ｄコンバータ２は電池３の電圧値をＡ／Ｄ変換し、ＬＥＤ制御部１に入力する。ＬＥＤ制御部１は、入力されたＡ／Ｄ変換値により電池レベルを判定し、電池レベルに応じてＬＥＤ１１の点灯回数を設定する。ＬＥＤ１１は携帯電話機の着信時の表示や、充電中か否かの状態表示を目的として設置されており、本実施例での電池残量表示をする場合には、ＬＥＤ制御部１の制御により、例えば電池レベル１に対しては点灯回数１回、電池レベル２に対しては点灯回数２回、電池レベル３に対しては点灯回数３回と設定する。図８の外観図によれば、ＬＥＤ１１は、折り畳んだ状態においても目視確認できるよう背面より発光する構造となっている。また、電池３への充電制御は充電制御部８により行われる。なお、充電時においては、Ａ／Ｄコンバータ２への入力は充電電圧印可された状態の電池電圧となるため、ＬＥＤ制御部１は「充電中」と判断する。
【００２６】
電話番号や電池残量等の各種情報の表示を行う表示部１０、および通話時や待ち受け時の各種操作を行うキー９については、図９の外観図に示すように、いずれも携帯電話機を折り畳んだ際に内側になる面に配置されているため、携帯電話機を開いた場合においてのみ有効となる。また、キー７は電池レベルの確認を行うためのキーであり、図８をみると折り畳んだ状態でも押下可能な位置（ここでは携帯電話機側面）に配置されている。
【００２７】
通常動作時において、ＬＥＤ制御部１は、キー７が押下されたことを検出すると、電池レベルに応じて設定された回数分ＬＥＤ１１を点灯させる。
【００２８】
一方充電時においては、前述の通りＬＥＤ制御部１は電池残量に関わらず「充電中」と判断し、充電中の状態の表示として、ＬＥＤ１１を連続点灯している。従って、充電時における電池レベル確認については、ＬＥＤ制御部１はキー７が押下を検出すると、充電制御部８に対して充電停止信号（Ｓｉｇ１）を出力して充電を一旦停止させ、電池レベルの判断結果に応じた回数分ＬＥＤ１１の点灯を行う。ＬＥＤの点灯が完了すると、ＬＥＤ制御部１は充電制御部８に対して充電開始信号（Ｓｉｇ２）を出力し充電を再開させる。充電再開後、再度充電中の状態の表示としてＬＥＤ１１を連続点灯する。
【００２９】
次に、本実施例における動作を、通常動作時と充電時に分けて説明する。
【００３０】
まず通常使用時における動作について、図１０および図１１に基づいて説明する。まず、図１０は電池レベルに応じたＬＥＤ点灯回数を設定する動作についてのフローチャートである。図１０を参照すると、まずＡ／Ｄコンバータ２が電池３の電圧値をＡ／Ｄ変換し、ＬＥＤ制御部１に入力する（Ｓ４１）。ＬＥＤ制御部１は入力されたＡ／Ｄ値により電圧レベルを監視し、電圧レベルの変化有無を判断する（Ｓ４２）。Ｓ４３において、電池レベルが変化した場合、ＬＥＤ制御部１は電池レベルの変化に応じてＬＥＤ１１の点灯回数を設定（変更）し（Ｓ４４）、Ｓ４１へ戻る。Ｓ４３において、電池レベルが変化しなかった場合は、ＬＥＤ１１の点灯回数の設定は変更せずに、Ｓ４１へ戻る。
【００３１】
次に、上記フローで設定された回数分ＬＥＤ１１を点灯させる動作について、図１１のフローチャートに基づいて説明する。図１１を参照すると、まずＬＥＤ制御部１がキー７押下による電池レベル確認要求の有無を検出する（Ｓ５１）。Ｓ５２において、電池レベル確認要求有りの場合、ＬＥＤ制御部１は電池レベルに応じた回数分ＬＥＤ１１を点灯させ（Ｓ５３）、Ｓ５１に戻る。Ｓ５２において、電池レベル確認要求無しの場合は、ＬＥＤ１１の点灯は行わず、再びＳ５１に戻る。
【００３２】
次に、充電時における動作について図１２に基づいて説明する。図１２を参照すると、まずＬＥＤ制御部１がキー７押下による電池レベル確認要求の有無を検出する（Ｓ６１）。Ｓ６２において、電池レベル確認要求有りの場合、ＬＥＤ制御部１は充電制御部８に対して充電停止信号（Ｓｉｇ１）を出力し充電を停止させ（Ｓ６３）、充電中を表示する”ＬＥＤ１１の連続点灯”を停止する（Ｓ６４）。充電停止後、Ａ／Ｄコンバータ２は電池３の電圧値をＡ／Ｄ変換し、ＬＥＤ制御部１に入力する（Ｓ６５）。ＬＥＤ制御部１は入力されたＡ／Ｄ値により電池レベルを判断し（Ｓ６６）、電池レベルに応じてＬＥＤの点灯回数を設定し（Ｓ６７）、設定された回数分ＬＥＤを点灯させる（Ｓ６８）。ＬＥＤ点灯完了後、ＬＥＤ制御部１は充電制御部８に対して充電開始信号（Ｓｉｇ２）を出力し、充電を再開させ（Ｓ６９）、充電中を表示する”ＬＥＤ１１の連続点灯”を再開し（Ｓ７０）、Ｓ６１に戻る。Ｓ６２において、電池レベル確認要求無しの場合は、再びＳ６１に戻る。
【００３３】
【発明の効果】
以上説明したように、本発明の折り畳み型携帯電話機の電池残量確認装置によれば、折り畳み時においても押下可能な位置に配置されたキーを押下することで、各電池レベルに応じたＬＥＤの点灯をさせ、本体を折り畳んだ状態においても電池レベルを確認することができる。これにより、折り畳み型携帯電話における電池レベルの確認を、本体を開くことなく行うことができるという効果がある。
【００３４】
また充電中においては、携帯電話機を充電器から外すことなく電池レベル確認を行うことが可能となる効果がある。
【００３５】
さらに、キーを押した際の一定時間のみＬＥＤを点灯させるので、余分な消費電流の増加も少なく、他のＬＥＤ表示とＬＥＤ兼用することにより、追加の部品も必要とはならない。

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a circuit configuration of the present embodiment, FIGS. 2 and 3 are external views when the present embodiment is realized in a foldable mobile phone, FIG. 2 shows a state in which the mobile phone is closed, FIG. FIG. 4 is a diagram showing a state in which the mobile phone is opened.
[0013]
According to FIG. 1, the circuit configuration of the present embodiment includes a battery 3 that is a main power source of a mobile phone, an A / D converter 2 that performs A / D conversion on the voltage value of the battery 3, and a circuit operation of the present embodiment. Operation of the LED control unit 1 to be controlled, LEDs 4, 5, 6 that are lit while distinguishing the remaining amount of the battery 3, the key 7 for checking the remaining amount of the battery 3, and the operation of the key 7 for checking the remaining amount The charging control unit 8 controls the suspension of battery charging in conjunction with the control signal and its control signal (Sig1 / Sig2).
[0014]
The A / D converter 2 performs A / D conversion on the voltage value of the battery 3 that is the main power source of the mobile phone, and inputs it to the LED control unit 1. The LED control unit 1 has several battery levels set according to the remaining battery level. The LED control unit 1 monitors the battery level based on the A / D conversion value input from the A / D converter 2, Determine whether the battery level has changed. In this embodiment, it is assumed that the battery level is set in three stages, the state where the remaining battery level is more than two-thirds is “battery level 3”, and the state where one-third to two-thirds is “ The state of “battery level 2” or less than one third is defined as “battery level 1”. In addition, the charging control unit 8 performs charging control of the battery 3 and constantly reports a state of charging or non-charging to the LED control unit 1 (Sig2). At the time of charging, the input to the A / D converter 2 is the battery voltage in a state where the charging voltage is applied, and therefore the LED control unit 1 determines that “charging” regardless of the remaining battery level.
[0015]
LED4, LED5, and LED6 are LEDs having different emission colors, and are installed for the purpose of displaying when a mobile phone receives an incoming call or whether the battery is being charged. When displaying the remaining battery level according to the present invention For example, under the control of the LED control unit 1, for example, the LED 4 is selected for the battery level 1, the LED 5 is selected for the battery level 2, and the LED 6 is selected for the battery level 3. As shown in the external view of FIG. 2, the LEDs 4, 5, and 6 are structured to emit light from the back surface so that they can be visually confirmed even in the folded state.
[0016]
As shown in the external view of FIG. 3, the display unit 10 for displaying various information such as a telephone number and the remaining battery level and the key 9 for performing various operations during a call or standby are folded. Since it is arranged on the inner surface, it can be visually confirmed only when the mobile phone is opened. Further, the key 7 is a key for confirming the battery level, and as shown in FIG. 2, the key 7 is disposed at a position where it can be pressed even in the folded state (here, the side surface of the mobile phone).
[0017]
During normal operation, when the LED control unit 1 detects that the key 7 has been pressed, the LED selected according to the battery level is lit for a certain period of time.
[0018]
On the other hand, at the time of charging, as described above, the LED control unit 1 determines that the battery is being charged regardless of the remaining amount of the battery, and the LED 6 is continuously lit as an indication of the charging state.
