In FIG. 1, reference numeral 100 denotes a microcomputer that controls the apparatus. The microcomputer 100 includes a CPU 101, a ROM 102, a RAM 103, an AD converter 104, a timer 105, a clock 106, and an IO 107.

Reference numerals 308 and 309 denote voltage dividing resistors for dividing the charging voltage and inputting it to the AD converter 104 in the microcomputer 100.

図２は本発明実施例のモード切り替え動作を示すフローチャートである。本機器の動作モードは充電モード、停止モード、起動モードの３つが存在する。ここで、充電モードとは、２次電池２００を充電するための動作モードである。起動モードとは、携帯機器が通常の使用可能な状態となるように起動し、起動完了後は使用可能な状態を維持するための動作モードである。停止モードとは、携帯機器の機能がモードの切り替え動作を除き停止している状態である。   FIG. 2 is a flowchart showing the mode switching operation of the embodiment of the present invention. There are three operation modes of the device: a charging mode, a stop mode, and a startup mode. Here, the charging mode is an operation mode for charging the secondary battery 200. The activation mode is an operation mode for starting the mobile device so as to be in a normal usable state and maintaining the usable state after the completion of the activation. The stop mode is a state in which the function of the mobile device is stopped except for the mode switching operation.

モードの切り替え動作は、一定の時間毎（例えば２秒毎）に実行する。まず、Ｓ２０１で充電電圧をマイコン１００のＡＤコンバータ１０４にて測定する。この電圧は本機器が充電器５００に載っている時にのみ発生する。次に、現在のモードに応じて処理が分岐する。なお、ＡＤコンバータ１０４にて測定された充電電圧は、マイコン１００のＲＡＭ１０３に順次記憶され、現在および過去の所定回数分（例えば、２回分）の充電電圧を記憶している。   The mode switching operation is executed at regular time intervals (for example, every 2 seconds). First, the charging voltage is measured by the AD converter 104 of the microcomputer 100 in S201. This voltage is generated only when the device is on the charger 500. Next, the process branches according to the current mode. The charging voltage measured by the AD converter 104 is sequentially stored in the RAM 103 of the microcomputer 100, and the charging voltage for the current and past predetermined times (for example, twice) is stored.

まず、現在のモードが充電モードの場合について説明する。
Ｓ２０２にてモードが充電モードか確認する。充電モードなので、Ｓ２０３に進み、Ｓ２０１で測定した充電電圧の有無を確認する。充電電圧が「有り」の場合、Ｓ２０４にて充電モードを再度設定して終了する。
Ｓ２０３にて充電電圧が「無し」の場合は、Ｓ２０５に進み、ＲＡＭ１０３に記憶されている前回（２秒前）の充電電圧を確認する。前回の充電電圧が「有り」の場合には、Ｓ２０４に進み充電モードを設定して終了する。前回の充電電圧が「無し」の場合には、Ｓ２１３に進み起動モードを設定して終了する。つまり、充電電圧が「２回連続無し」の場合に起動モードに切り替わり、それ以外の場合に充電モードを維持することとなる。 First, the case where the current mode is the charging mode will be described.
In S202, it is confirmed whether the mode is a charge mode. Since it is the charging mode, the process proceeds to S203, and the presence / absence of the charging voltage measured in S201 is confirmed. If the charging voltage is “present”, the charging mode is set again in S204 and the process is terminated.
When the charging voltage is “none” in S203, the process proceeds to S205, and the previous charging voltage (2 seconds before) stored in the RAM 103 is confirmed. When the previous charging voltage is “present”, the process proceeds to S204, where the charging mode is set and the process ends. If the previous charging voltage is “none”, the process proceeds to S213, where the start mode is set and the process ends. That is, when the charging voltage is “no two consecutive times”, the mode is switched to the start mode, and otherwise the charging mode is maintained.

次に、現在のモードが起動モードの場合について説明する。
Ｓ２０２にて充電モードか確認し、充電モードではないのでＳ２１０に進む。Ｓ２１０にて起動モードか確認する。起動モードなので、Ｓ２１１に進み、Ｓ２０１で測定した充電電圧の有無を確認する。
Ｓ２１１にて充電電圧が「有り」の場合は、Ｓ２１２に進み、ＲＡＭ１０３に記憶されている前回（２秒前）および前々回（４秒前）の充電電圧を確認する。前回および前々回の充電電圧のいずれも「有り」の場合には、Ｓ２０４に進み充電モードを設定して終了する。前回および前々回の充電電圧のいずれか一方が「無し」の場合には、Ｓ２１３に進み起動モードを設定して終了する。つまり、充電電圧が「３回連続有り」の場合に充電モードに切り替わることとなる。 Next, the case where the current mode is the startup mode will be described.
In S202, it is confirmed whether the charging mode is set. Since the charging mode is not set, the process proceeds to S210. In S210, it is confirmed whether the activation mode is set. Since it is a starting mode, it progresses to S211 and the presence or absence of the charging voltage measured by S201 is confirmed.
If the charge voltage is “Yes” in S211, the process proceeds to S212, and the previous (2 seconds before) and last (4 seconds) charge voltages stored in the RAM 103 are confirmed. If both of the previous and previous charging voltages are “present”, the process proceeds to S204, where the charging mode is set and the process ends. If either one of the previous and previous charging voltages is “None”, the process proceeds to S213, where the start mode is set and the process ends. That is, when the charging voltage is “continuous 3 times”, the mode is switched to the charging mode.

Ｓ２１１にて充電電圧が「無し」の場合は、Ｓ２１４に進み、ＲＡＭ１０３に記憶されている前回（２秒前）および前々回（４秒前）の充電電圧を確認する。前回および前々回の充電電圧のいずれか一方のみが「有り」の場合には、Ｓ２１３に進み起動モードを設定して終了する。前回および前々回の充電電圧のいずれも「有り」の場合には、Ｓ２２１に進み起動モードを設定して終了する。つまり、充電電圧が今回は「無し」であって前回および前々回が共に「有り」の場合に停止モードに切り替わることとなる。   When the charge voltage is “none” in S211, the process proceeds to S214, and the previous (2 seconds before) and last (4 seconds) charge voltages stored in the RAM 103 are confirmed. When only one of the previous and previous charging voltages is “present”, the process proceeds to S213, the start mode is set, and the process is terminated. If both of the previous and previous charging voltages are “present”, the process proceeds to S221 and the start mode is set and the process ends. That is, when the charging voltage is “none” this time and both “presence” and “previous” are both “present”, the mode is switched to the stop mode.

次に現在のモードが停止モードの場合について説明する。
Ｓ２０２にて充電モードか確認し、充電モードではないのでＳ２１０に進む。Ｓ２１０にて起動モードか確認し、起動モードではないのでＳ２２０に進む。Ｓ２２０にて、Ｓ２０１で測定した充電電圧の有無を確認する。
Ｓ２２０にて充電電圧が「無し」の場合は、Ｓ２２１に進み、停止モードを設定して終了する。 Next, the case where the current mode is the stop mode will be described.
In S202, it is confirmed whether the charging mode is set. Since the charging mode is not set, the process proceeds to S210. In S210, it is confirmed whether the activation mode is selected. Since the activation mode is not selected, the process proceeds to S220. In S220, the presence or absence of the charging voltage measured in S201 is confirmed.
If the charge voltage is “none” in S220, the process proceeds to S221, the stop mode is set, and the process ends.

Ｓ２２０にて充電電圧が「有り」の場合は、Ｓ２２２に進み、ＲＡＭ１０３に記憶されている前回（２秒前）および前々回の充電電圧を確認する。前回および前々回の充電電圧のいずれも「有り」の場合には、Ｓ２０４に進み充電モードを設定して終了する。前回および前々回の充電電圧のいずれか一方が「無し」の場合には、Ｓ２２１に進み停止モードを設定して終了する。つまり、充電電圧が「３回連続有り」の場合に充電モードに切り替わることとなる。   If the charge voltage is “Yes” in S220, the process proceeds to S222, and the previous (two seconds before) and previous charge voltages stored in the RAM 103 are confirmed. If both of the previous and previous charging voltages are “present”, the process proceeds to S204, where the charging mode is set and the process ends. If either one of the previous and previous charging voltages is “none”, the process proceeds to S221 and the stop mode is set and the process ends. That is, when the charging voltage is “continuous 3 times”, the mode is switched to the charging mode.

以上のように、携帯機器の外部に動作モードの切り替えスイッチがなくても、携帯機器を充電器に載せるタイミングに応じて動作モードを切り替えることができる。
なお、第１の実施形態においては、Ｓ２０５，Ｓ２１２，Ｓ２１４，Ｓ２２２におけるモードの切り替え条件は、上記の説明および図２におけるフローチャートに限定されることはなく、予めマイコン１００に任意に決定した切り替え条件を設定することができる。例えば、Ｓ２１２およびＳ２２２の充電モードへの切り替え条件を、５回連続充電電圧がある場合に充電モード切り替えるように設定しても良い。 As described above, the operation mode can be switched according to the timing of placing the portable device on the charger without the operation mode changeover switch outside the portable device.
In the first embodiment, the mode switching conditions in S205, S212, S214, and S222 are not limited to the above description and the flowchart in FIG. Can be set. For example, the switching condition to the charging mode in S212 and S222 may be set so that the charging mode is switched when there are five continuous charging voltages.

さらに、ＬＥＤ４０１を動作モードに対応して点灯させることにより動作モードを可視化することも可能である。例えば、停止モード時は消灯、起動モード時は２秒間に１回点灯、充電モード時は２秒間に２回点灯とするということで実現できる。   Further, the operation mode can be visualized by turning on the LED 401 corresponding to the operation mode. For example, it can be realized by turning off the light in the stop mode, lighting once in 2 seconds in the start mode, and lighting twice in 2 seconds in the charging mode.
