Abstract

PURPOSE:To use the power of a power supply efficiently by providing an electronic equipment capable of employing a plural kind of power supplies with a means selecting a plural kind of functions in response to the kinds of the power supplies. CONSTITUTION:The connection of a dry cell 1 is detected by a detector 3, the connection of an AC adapter 2 is detected by a detector 4, and the detecting values are input to a control section 12. A power-supply secondary side unit 5 produces electronic-equipment exclusive voltage from the dry cell 1 or the AC adapter 2, and supplies power supply control sections 9-11 with electricity. The power supply control sections 9-11 feed a printer 6, an indicator 7 and an interface circuit with power. The control section 12 selects the power supply control sections 9-11 in response to the capacity of a power supply connected. The interface circuit at the low priority order is not supplied with electricity when only the dry cell 1 is connected, and all load is fed with electricity when the AC adapter 2 is connected. Accordingly, the power of the power supply is used efficiently.

の機能を選択するものである。In the figure, 1 is a dry battery as a power source, 2 is an AC adapter as a power source, 3 is a detector for checking the presence or absence of the dry cell battery 1, 4 is a detector for checking the presence or absence of the AC adapter 2, and 5 is a dry cell battery 1 or an anal adapter. 2 is a power supply secondary side unit that produces a dedicated voltage for electronic devices, 6 is a printer, 7 is a display, 8 is an interface circuit that can be attached to the main body, 9 is a power supply control section of the printer 6, and 1O is a power supply control unit of the display 7. A power supply control section 11 is a power supply control section of the interface circuit 8, and 12 is a control section, which serves as a selection means and selects a predetermined function according to the power supply capacity of the power source used.

次に、動作を説明する。Next, the operation will be explained.

電力供給能力が充分なＡＣアダプタ２が本体に装着され
た場合は、検出器４から制御部１２へ検出信号が出力さ
れ、制御部１２により各電源供給コントロール部９．１
０．１１へ電源供給信号が送られ、電子機器の全機能の
動作が許可される。When the AC adapter 2 with sufficient power supply capacity is attached to the main body, a detection signal is output from the detector 4 to the control unit 12, and the control unit 12 controls each power supply control unit 9.1.
A power supply signal is sent to 0.11, allowing all functions of the electronic device to operate.

他方、電力供給能力の劣る乾電池１が本体に装着された
場合は、検出器３から制御部１２へ検出信号が出力され
、制御部１２により電源供給コントロール部１１に信号
が送られ、本体機能の優先順位の低いインターフェイス
回路８への電力供給が停止され、乾電池ｌの供給可能な
電力で動作しつる機能に限定し、本体動作を許可する。On the other hand, when a dry battery 1 with poor power supply capacity is installed in the main body, a detection signal is output from the detector 3 to the control section 12, and the control section 12 sends a signal to the power supply control section 11, which controls the main body functions. The power supply to the lower priority interface circuit 8 is stopped, and the main body operation is allowed to operate with the power that can be supplied by the dry cell battery 1, and is limited to the operating function.

なお、未実施例では、乾電池１が本体に装着されている
場合、本体機能の優先順位が低いものの使用を禁止する
例を説明したが、使用者がプリンタ６、表示器７．イン
ターフェイス８の中から禁止する機能を選択するように
してもよい。In the unimplemented example, an example was explained in which when the dry cell battery 1 is installed in the main body, the use of the main body functions with a low priority is prohibited, but the user does not want to use the printer 6, the display 7, etc. The function to be prohibited may be selected from the interface 8.
