にとどめられる。A considerable amount of space is required to attach a currently commercially available light-receiving element to a liquid crystal display, but if the method of the present invention, in which the light-receiving element is formed directly on the panel glass surface by vapor deposition, etc., it can be mounted easily. The space for this is kept to a minimum.
この方式は腕時計の如く収容体積に限定のあるものでは
非常なる優位性が得られるものである。This method is extremely advantageous for items such as wristwatches, which have a limited storage volume.
又、必要に応じてネサ膜と同一面に受光素子を形成する
ことにより、引き出し線等がネサ膜と同一面上に構成で

ことが可能である。Dots for distinguishing hours and minutes shown in Figure 2a, Figure 2b
It is possible to form a mark such as a name plate shown in FIG.
つまり、この手段により表示体部のパネルガラス面に形
成された受光素子に静的な表示と外部指令信号の検出と
いう２つの機能を与えることができ、しかも必要最少限
のスペースで済ませることが可能である。In other words, by this means, it is possible to give the light-receiving element formed on the panel glass surface of the display body the two functions of static display and detection of external command signals, and it can be done using the minimum necessary space. It is.
この手段は、時計の如く収容限度のあるものについては
可能な限り小型化しなければならない必要性から非常に
有効である。This method is very effective because it is necessary to reduce the size of an item such as a watch that has a limited storage capacity as much as possible.
受光素子としてｃｄｓ等の光導電素子を用いた場合には
、次に示す如く外部から光によって与えられる指令信号
を検出し、時計体内部の電子回路を無接触で動作可能と
する。When a photoconductive element such as a CDS is used as a light receiving element, a command signal given by light from the outside is detected as shown below, and the electronic circuit inside the watch body can be operated without contact.
第３図に示す回路で、ｃｄｓ８は入射光のない時暗抵抗
が高く光が照射されると低抵抗となる機能を利用すれば
、次段の相補型ＭＯＳインバーター９をスイッチングさ
せることが可能である。In the circuit shown in Fig. 3, the CDS8 can switch the complementary MOS inverter 9 in the next stage by using the function that the dark resistance is high when there is no incident light and the resistance becomes low when the light is irradiated. be.
液晶表示時計で、この原理を応用すれば時、分、秒の修
正スイッチ、時間計測と時刻表示の切り換えスイッチ、
各種切り換えスイッチ等のスイッチとして使用でき、し
かも従来のスイッチの様に接触型のものでなく、光によ
る完全無接触のスイッチとして使用可能である。If you apply this principle to a liquid crystal display watch, you can use a switch to correct hours, minutes, and seconds, a switch to change between time measurement and time display,
It can be used as a switch such as various changeover switches, and it can be used as a completely non-contact switch using light instead of a contact type switch like conventional switches.

発明の受光素子を働かすことが可能である。Further, as shown in FIG. 4, a detection circuit 10 detects a standard time signal given from the outside, and a counter 12 counts the deviation from the signal from the time standard source 11 inside the watch body. The present invention can be used as an external command signal detection means for a timepiece having an internal mechanism for controlling the gate 14 to vary the frequency division ratio of the frequency dividing circuit 13 to adjust the rate of the timepiece body, that is, a liquid crystal display timepiece having a logical adjustment means. It is possible to make use of several light receiving elements.
