Abstract

PURPOSE:To know a battery voltage by providing an external data device with a level meter which displays the voltage level and its changeover switch, and displaying the battery voltage of the electronic timepiece on the level meter. CONSTITUTION:The source voltage of the external data device A is displayed on the level meter 1 through a power circuit 3 and the switch 2 all the time. Then, the voltage level of transmitted data from the data transmitting circuit 6 of the electronic timepiece is equal to the source voltage of the timepiece and the voltage level is detected by a voltage detecting circuit 4 from the data received by a data receiving circuit 5. Then, the switch 2 is turned on to display the source voltage of the timepiece B on the level meter 1.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the display of battery voltage in electronic watches [Prior Art] Conventional electronic watches only notify the battery consumption when the battery voltage drops below a certain level. Therefore, it was not possible to know the battery voltage of the electronic watch.

〔the purpose〕

The present invention is intended to solve these problems, and its purpose is to provide a level meter for determining the battery voltage of an electronic watch.

〔overview〕

The battery voltage level meter for an electronic watch of the present invention is an external data device that receives data from the electronic watch via a cable, and includes a level meter that displays a voltage level on the external data device, and a level meter that displays the voltage level on the external data device. A changeover switch is installed, and the level meter displays the power supply voltage of the external data device and, by changing the changeover switch, displays the battery voltage of the electronic timepiece. do.

〔Example〕

Hereinafter, the present invention will be described in detail based on examples.

FIG. 1 shows a block diagram for displaying the battery voltage of an electronic watch. The external data device A includes a level meter 1 for displaying voltage, a switch 2 for switching between the power supply voltage of the external data device A and the battery voltage of the electronic clock B, a power supply circuit 3 for supplying power, and a power supply circuit 3 for the electronic clock B. It is comprised of a voltage detection circuit 4 that detects battery voltage and a data reception circuit 5 that receives data from an electronic clock B. The data transmission circuit 6 of the electronic watch B transmits the data of the electronic watch B.

The power supply voltage of external data device A is the power supply voltage of external data device A.
The signal is then applied to the level meter 1 via the switch 2 and displayed at all times.

On the other hand, since the voltage level of the transmitted data of electronic timepiece B is equal to the battery voltage of electronic timepiece B, the voltage level of the transmitted data is displayed instead of the battery voltage.

- Transmission data from the electronic timepiece B is transmitted by the data transmission circuit 6 of the electronic timepiece B, and is received by the data reception circuit 5 of the external data device A via the cable 1. The voltage level of the received data is detected by the voltage detection circuit 4 and is applied to the switch 2 . When the switch 2 is turned on, the level meter 1, which has been displaying the power supply voltage of the external data device A, displays the battery voltage of the electronic clock B.

〔effect〕

As described above, according to the present invention, the battery voltage of the electronic timepiece can be displayed on the level meter simply by connecting the electronic timepiece and an external data device with a cable and turning on a switch. In addition, this allows the user to know the state of battery consumption in more detail. Furthermore, in the cable that connects an external data device and an electronic watch, the battery voltage of the electronic watch is displayed using the transmitted data, so there is no need for a core wire that transmits the battery voltage in addition to the core wire that transmits data. In small-sized devices, the size of the cable connection is important, so displaying battery voltage using transmitted data is very effective. It has the above effects. 1
