Description

  The invention described in the claims of the present application includes a battery forming a power supply unit of an electronic device main body device and a power supply unit of an electronic device remote operation control unit provided separately from the electronic device main body device. The present invention relates to a battery electromotive force state display device capable of displaying the battery electromotive force state of each battery.

  In the field of electronic equipment such as a compact disc (CD) player and a mini disc (MD) player, a remote operation control device that is provided separately from the main body device and controls the operation of the main body device, etc. Those equipped with are widely put into practical use. Such an electronic device is not only a stationary type in which the main body apparatus is installed and used in a predetermined place, but the main body apparatus is relatively small and is carried and used. Often it is portable.

  In either of these stationary electronic devices and portable electronic devices, in order to improve usability, the remote operation control device is not connected to the main device by wire, and the operation control for the main device is performed wirelessly. It is known to perform by communication. A remote operation control device that performs operation control on the main body device by wireless communication is required to have a power supply unit that supplies operation power, but in order to improve operational convenience, usually the power supply The unit is constituted by a battery attached to the remote control device.

  In the case of the portable electronic device described above, since the main body device is carried, the power supply unit of the main body device is usually constituted by a battery attached to the main body device. Therefore, in a portable electronic device equipped with a remote operation control device that performs operation control on the main device by wireless communication, both the main device and the remote operation control device normally constitute respective power supply units. A battery is to be attached.

  Batteries constituting a power supply unit in various electronic devices and the like are required for the power supply unit when the electromotive force gradually decreases according to the use state after the start of use, and the electromotive force falls below a predetermined level. It becomes impossible to supply only the power, and the function of the power supply unit is lost. Therefore, in each of the main body device and the remote control device to which the battery constituting the power supply unit is attached, the attached battery is attached in order to avoid a situation in which the function of forming the power supply unit is lost. It is desired that the user can recognize the electromotive force state of the battery, and that the attached battery can be replaced with a new battery before the attached battery loses the function of forming the power supply unit.

  Under such circumstances, conventionally, an electronic apparatus including a main body device and a remote operation control device provided separately from the main body device, and an electromotive force state of a battery constituting a power supply unit of the main body device, or It has been proposed that the user can recognize the electromotive force state of the battery constituting the power supply unit of the remote operation control device on the main device side or the remote operation control device side (for example, a patent). References 1 and 2).

  In an electronic device provided with a conventionally proposed main body device and a remote operation control device, in which the electromotive force state of the battery constituting the power supply unit of the main body device can be confirmed, the main body device, For example, it is a small acoustic device to which a headphone is connected, and the remote operation control device provided separately from the main body device is an operation key used for remote operation of the small acoustic device, for example. The operation mode name sound corresponding to the signal indicating the operation mode from the key is emitted from the headphone connected to the small acoustic device, and the pitch of the operation mode name sound of the battery constituting the power supply unit of the small acoustic device is It is made to change according to a consumption condition (battery electromotive force fall state). In addition, the above-described battery consumption state is displayed on a display unit provided in the small acoustic device. Thereby, the electromotive force state of the battery constituting the power supply unit of the small acoustic device can be confirmed audibly and visually.

  In addition, in an electronic device provided with a conventionally proposed main body device and a remote operation control device, in which an electromotive force state of a battery constituting a power supply unit of the remote operation control device can be confirmed, For example, the main body device is a television receiver, and the remote operation control device provided separately from the main body device is, for example, a transmitter used for remote operation of the television receiver. Display or notification that the battery constituting the power supply unit of the device has been exhausted (battery electromotive force has decreased) is performed using an image display screen or a speaker in the television receiver. Thereby, the electromotive force state of the battery forming the power supply unit of the transmitter can be confirmed audibly or visually.

  Thus, when the electromotive force state of the battery constituting the power supply unit of the electronic device main body device or the electronic device remote operation control device is displayed on the electronic device main body device or the electronic device remote operation control device, for example, as shown in FIG. As shown, a display unit 11 having a liquid crystal display panel is used.

The display unit 11 shown in FIG. 9 is provided, for example, in an electronic device remote control device attached to an audio signal reproduction device which is an electronic device main body device, and an electromotive force of a battery constituting a power supply unit of the audio signal reproduction device The figure 12 representing the state is displayed on one screen of the display area on the display panel. The graphic 12 is displayed as having a different shape, for example, as shown in A, B, C, and D of FIG. 10 according to the electromotive force state of the battery constituting the power supply unit of the audio signal reproducing device. A graphic 12 shown in A of FIG. 10 indicates that the electromotive force of the battery constituting the power supply unit of the audio signal reproducing device is almost not lowered, and the graphic 12 shown in B of FIG. The figure 12 shown in FIG. 10C shows that the electromotive force of the battery constituting the power supply unit of the audio signal reproducing apparatus has considerably decreased, indicating that the electromotive force of the battery constituting the power supply unit of the reproducing apparatus is slightly lowered. The graphic 12 shown in D of FIG. 10 shows that the battery is in a state where the electromotive force of the battery constituting the power supply unit of the audio signal reproducing device is significantly reduced, that is, the battery is replaced with a new battery. It means that the time to do it has arrived. Such a display graphic representing the battery electromotive force state such as the graphic 12 is usually relatively large in order to facilitate visual inspection.
