Abstract

PURPOSE:To permit immediate identification of whether a battery is branded new or not when said battery is switched on and to make displaying of an accurate usable time possible by displaying in converting the voltage of the battery to a battery life time upon switching of said battery and substracting the display at every specified period. CONSTITUTION:When a battery E is switched on, the voltage thereof is detected with a detecting circuit A, and the remaining life time of the battery is converted to, for example, a usable number of days or months by a converting circuit M. On the other hand, differential pulses are generated from a differentiating circuit K upon switching of the battery E, and are supplied to a subtraction counter DC with slight delay, so that the output of the circuit M is preset. Pulses are supplied at every specified period, for example, every one day or one month from a clock circuit to the terminal P2 of the circuit DC, by which the pulses are subtracted. The life time of the battery is displayed on a display device DP via the output of the counter DC.

Description

【発明の詳細な説明】 本発明は時計などの電池寿命表示装置ＶＣ関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery life display device VC for a watch or the like.

起こりうるものである。Conventionally, for example, when displaying the battery life of a watch, a battery was inserted and the battery life was displayed. There is a device that starts a counter from 7 and crocodile, and after a certain period of time has elapsed, displays the battery life based on the output of the counter. However, according to this, there is no problem if a new battery is used, but if a slightly worn-out battery is inserted, the battery will run out before the life display is displayed. Since it is difficult to tell whether a battery is new or not by looking at it, the above-mentioned problem often occurs.

とに減算していくようにしたものである。Therefore, according to the present invention, when a battery is inserted, the voltage is displayed as the remaining battery life time, and this display is subtracted at regular intervals.

The setting is such that, for example, when tsv, 1.4V, and tsV are detected, 1 nocilus is generated from bs. These are a KFi differential circuit, a d delay circuit, and a G gate circuit.

。In the above configuration, each time the battery I is inserted, its voltage is detected by the detection circuit M, and converted by the variable circuit M into the remaining 90 battery life hours, or the number of days or months that can be used. On the other hand, when the battery IC is turned on, the differential signal 25 is input to the differentiating circuit, and is slightly delayed and supplied to the subtraction counter DC, so that the output of the conversion circuit M is preset. A clock circuit (not shown) is applied to terminal P2 of the subtraction circuit DC at a fixed period, for example, every day or #i.
Every month, Nokurusuka is supplied and subtracted. It is displayed on the display device #DP via the output of the subtraction counter DC.

カウンタＤＣにプリセットして誤差時間を修正するもの
である。In this way, the remaining battery life time is subtracted at regular intervals, or in the case of devices with loads such as alarm clocks and hourly clocks, the degree of battery consumption varies depending on the frequency of use. Therefore, the control circuit B generates a pulse when the battery voltage reaches 1.5V, 1.4V, and t3VK, and corrects the error time by presetting the output of the conversion circuit M for each voltage and t into the subtraction counter DC. It is something to do.

That is, since the Fi battery voltage drops when the load is driven, the voltage is kept high so that the voltage of any battery is not detected.
