Abstract
Description
【発明の詳細な説明】 本発明は時計の電池寿命表示装置に関するものである。[Detailed description of the invention] The present invention relates to a battery life display device for a watch.
従来、秒針を有した3針時計では秒針を例えば2秒ごと
に運針して電池寿命表示を行なうものがあるが、秒針を
有さない2針時計ではこの方法は適用できない。そのた
め発光素子を点灯して電池寿命表示を行なうなど、寿命
表示用の構成を必要とするものであった。Conventionally, some three-hand watches with a second hand display battery life by moving the second hand every two seconds, but this method cannot be applied to two-hand watches without a second hand. Therefore, a configuration for displaying battery life is required, such as lighting a light emitting element to display battery life.
そこで本発明は分針を振動させることによって電池寿命
表示を行なうようにしたものである。Therefore, the present invention displays the battery life by vibrating the minute hand.
以下本発明の一実施例を図面に基づいて説明する。第1
図において、Qは水晶発振器、Dは分周器、Aは電池寿
命の検出回路、Bは制御回路、DRはモータMの駆動回
路である。モータMの回転は輪列(図示せず。)を介し
て分針常および時針りを歩進する。An embodiment of the present invention will be described below based on the drawings. 1st
In the figure, Q is a crystal oscillator, D is a frequency divider, A is a battery life detection circuit, B is a control circuit, and DR is a motor M drive circuit. The rotation of the motor M advances the minute hand and the hour hand through a gear train (not shown).
モータMは第3図に示すようなステップモータテ、ロー
タRの静的安定位置α−αはステータSのノツチの位置
によって決まる。b−bは動的安定位置である。The motor M is a step motor as shown in FIG. 3, and the static stable position α-α of the rotor R is determined by the position of the notch of the stator S. bb is the dynamic stable position.
以上の構成において、電池電圧が十分あるときは検出回
路Aから出力は発生せず制御回路Bから1分ごとにパル
スが発生しモータMの駆動コイル(図示せず。)には第
2図工のごとくパルスが印加される。これによってロー
タRは180°回転され、分針は1分歩進される。In the above configuration, when the battery voltage is sufficient, no output is generated from the detection circuit A, and a pulse is generated from the control circuit B every minute, and the drive coil of the motor M (not shown) is A pulse is applied as shown in FIG. As a result, the rotor R is rotated by 180 degrees, and the minute hand is advanced by one minute.
そして電池が消耗して検出回路Aから出力が発生すると
、制御回路Bからは1〜5秒ごとにパルスが発生し駆動
コイルには第2図■のごとくパルスが印加される。ロー
タRが回転した後、同極性のパルスが印加されると、ロ
ータRは静的安定位置から動的安定位置まで回転する。When the battery is exhausted and an output is generated from the detection circuit A, a pulse is generated from the control circuit B every 1 to 5 seconds, and the pulse is applied to the drive coil as shown in FIG. 2 (2). After the rotor R rotates, when pulses of the same polarity are applied, the rotor R rotates from a static stable position to a dynamic stable position.
したがって同極性のパルスが連続的に印加されると、ロ
ータRは静的安定位置と動的安定位置の間を往復するこ
とになり、表示時刻が狂うことなく分針溝が振動する。Therefore, when pulses of the same polarity are continuously applied, the rotor R reciprocates between the static stable position and the dynamic stable position, and the minute hand groove vibrates without the displayed time being out of order.
これによって電池寿命を知ることができる以上のように
本発明によれば、2針時計において新たに表示装置を付
加することなく電池寿命を表示することができる。According to the present invention, the battery life can be displayed in a two-hand watch without adding a new display device.
