Description
【発明の詳細な説明】
本発明は時計のベル用モータ駆動回路に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a motor drive circuit for a watch bell.
ベルによってアラーム音を発生する時計において、Ｍｆ
ｉｎな構成で音量を調整するには駆動トランジスタの
ベースに可変抵抗を挿入して調整することが考えられる
が、以下の欠点があるため実用化は困難であった。In a clock that generates an alarm sound by a bell, Mf
In order to adjust the volume with an in-line configuration, it is conceivable to insert a variable resistor into the base of the drive transistor, but it has been difficult to put it into practical use because of the following drawbacks.
電池電圧が１．５ Ｖの状態でボリウムを小さく絞った
とき小さな音量になるように抵抗値を選ぶと、電池電圧
が１．２ｖ程度に低下したときベル音が鳴らなくなって
しまう。逆Ｋ １．２ Ｖ程度でもベル音が鳴るように
抵抗値を選ぶと、１．５ Ｖのときには飽和してしまっ
てボリウムによる調整がきかなくなってしまう。If you choose a resistance value so that the volume will be small when the volume is turned down when the battery voltage is 1.5 V, the bell will stop ringing when the battery voltage drops to about 1.2 V. If the resistance value is chosen so that a bell sound will be heard even at 1.2 V, the resistance will be saturated at 1.5 V and adjustment using the volume control will no longer be possible.
すなわちボリウムによって有効に調整が行なえる電圧範
囲が狭く、実用に供さないものであった０そこで本発明
は一定時間ごとに大電流によって直流モータを付勢する
ことてより電池電圧が低下してもベル音を鳴らせるよう
にしたものである。In other words, the voltage range that can be effectively adjusted by the volume control is narrow, making it impractical. Therefore, the present invention energizes the DC motor with a large current at regular intervals to reduce the battery voltage. It is also designed to make a bell sound.

５は直流モータで、ンユモク（図示せず。）を駆動して
リン（図示せず。）を打撃するものである。Reference numeral 5 denotes a DC motor that drives a nyumoku (not shown) to strike a phosphor (not shown).
６は直流モータ５の駆動トランジスタ、７は音量調整用
抵抗である。８はアラームスイッチ、９は鳴止めスイッ
チ、１０は第１および第２の駆動回路を構成する駆動制
御回路である。6 is a drive transistor for the DC motor 5, and 7 is a volume adjustment resistor. 8 is an alarm switch, 9 is a ring stop switch, and 10 is a drive control circuit constituting the first and second drive circuits.
以上の構成において、設定時刻にアラームスイッチ８が
閉じて端子ａが第２図ａのように１’ １ Ｉ＋になる
と駆動制御回路１０の端子すから第２図すの一定周期の
駆動パルスが生じる。このうち最初の駆動パルスによっ
て直流モータ５が起動される。In the above configuration, when the alarm switch 8 is closed at the set time and the terminal a becomes 1' 1 I+ as shown in FIG. . The DC motor 5 is started by the first drive pulse.
一方、端子Ｃからは第２図Ｃのように上記最初の駆動パ

タ５には定常駆動出力が供給される。On the other hand, an output is generated from the terminal C after the first drive pulse is generated, as shown in FIG. 2C, and is supplied to the drive transistor 6 via the resistor 7. As a result, a steady drive output is supplied to the DC motor 5.
また端子すからの一定周期の駆動パルスは直接駆動トラ
ンジスタ６に供給されるため、直流モータ５には一定周
期で定常駆動出力より大きな駆動出力が供給され付勢さ
れる。Furthermore, since the drive pulses at a constant period from the terminal are directly supplied to the drive transistor 6, the DC motor 5 is supplied with a drive output larger than the steady drive output at a constant cycle and is energized.
したがって抵抗７によってボリウムを絞った状態で電池
電圧が低下し、従来ではベル音が停止した状態でも、駆

す。また駆動パルスは抵抗７を介さないため、抵抗７と
して大きな抵抗値のものを用いしかもボリウムが絞られ

鳴らすことができる。Therefore, when the volume is turned down by the resistor 7, the battery voltage decreases, and even when conventionally the bell sound has stopped, the bell sound can be heard by being energized by the drive pulse. Further, since the driving pulse does not pass through the resistor 7, even if a large resistance value is used as the resistor 7 and the volume is turned down, the driving pulse can make a bell sound at a constant period.
以上のように本発明によれば、直流モータは一定周期で
大きな駆動出力で付勢されるため、電池電圧が低下して
もベル音を鳴らすことができる。As described above, according to the present invention, since the DC motor is energized with a large drive output at regular intervals, it is possible to make a bell sound even if the battery voltage decreases.
