しかしながら発光ダイオードを用いた時計、あるいは、
従来の文字板を使用した時計よりも薄暗い場所では表示
が見難かったり完全に見えないという欠点を有している
。However, watches using light emitting diodes or
Compared to watches using conventional dials, they have the disadvantage that the display is difficult to see or cannot be seen at all in dimly lit places.
そこでランプ等の照明装置をムーブメントの中に入れる
事が望ましいが、その際に問題となるのは、時計の様に
狭い空間に適当に配置し、尚且つ、衝撃時に破損しない
事が望ましい。Therefore, it is desirable to put a lighting device such as a lamp inside the movement, but the problem in doing so is that it should be placed appropriately in a narrow space like a watch, and it should also not be damaged by impact.
又万−ランプが切れた場合に於いても簡単に交換出来る
事が望ましい。It is also desirable that the lamp can be easily replaced even if it burns out.
本発明は上記の点に着目し、液晶表示デジタル時計にラ
ンプ機能を付加した時計の簡単なムーブメント構造を提
供する。The present invention focuses on the above points and provides a simple movement structure for a liquid crystal display digital timepiece with a lamp function added thereto.
以下図面に基づいて本発明を詳細に説明するが、本発明

略してある。The present invention will be described in detail below based on the drawings, but parts unrelated to the gist of the invention are omitted for the sake of simplification of the drawings.
第１図は本発明の平面図であり、一部セル部分を破断し
てある。FIG. 1 is a plan view of the present invention, with some cells cut away.
第２図は第１図のＩ−１断面図である。FIG. 2 is a sectional view taken along line I-1 in FIG. 1.
第１，２図に於い１は液晶セル、２は前記液晶セルを支
持するセル支持枠、３は基板支持受でチューブ４が押し
込まれている。In FIGS. 1 and 2, 1 is a liquid crystal cell, 2 is a cell support frame for supporting the liquid crystal cell, and 3 is a substrate support into which a tube 4 is pushed.
５は液晶セル１を押えるセル押えでありネジ６により固
定される。Reference numeral 5 denotes a cell holder for holding down the liquid crystal cell 1, and is fixed with screws 6.
７は上偏光板、８は下偏光板で液晶セル１に接着されて
いる。7 is an upper polarizing plate, and 8 is a lower polarizing plate, which are bonded to the liquid crystal cell 1.
９は反射板であり、１０はスペーサーであり、下偏光板
８と反射板９の間を光が通過するための隙間を確保する
スペーサーである。9 is a reflecting plate, and 10 is a spacer, which secures a gap for light to pass between the lower polarizing plate 8 and the reflecting plate 9.
１１は回路基板、１２は液晶セル１と回路基板１１の電
気的導通を取るコネクターである。11 is a circuit board; 12 is a connector for electrically connecting the liquid crystal cell 1 and the circuit board 11;
１３はランプであり１４はランプ接点バネであり、ピン
２１で位置決めされ、ビョウ１５によってセル支持枠２
に固定されている。Reference numeral 13 indicates a lamp, and reference numeral 14 indicates a lamp contact spring, which is positioned by a pin 21 and attached to the cell support frame 2 by a pin 15.
is fixed.
前記ランプ接点バネ１４の１４ａ部が弾性部を有してお
り、ネジ６を締めた時に１４ａ部が回路基板１１上の電
極とバネ接触し、電気的導通が取れる。A portion 14a of the lamp contact spring 14 has an elastic portion, and when the screw 6 is tightened, the portion 14a comes into spring contact with an electrode on the circuit board 11, thereby establishing electrical continuity.
又、ランプ接点バネ１４の１４ｂ部分でランプ１３のリ
ード線１５とハンダ等で固着されている。Further, a portion 14b of the lamp contact spring 14 is fixed to the lead wire 15 of the lamp 13 with solder or the like.
１７はランプスイッチバネでピン１８で位置決めされ、
ビョウ１９，２０でセル支持枠２に固定されている。17 is a lamp switch spring positioned by pin 18;
It is fixed to the cell support frame 2 with brackets 19 and 20.
ランプ１３の他方のリード線１６はランプ１３の１７ａ
部分にハンダ等で固着されている。The other lead wire 16 of the lamp 13 is 17a of the lamp 13.
It is fixed to the part with solder etc.
ランプスイッチバネ１７はセル支持枠２の２ａ部分で支
持されている。The lamp switch spring 17 is supported by a portion 2a of the cell support frame 2.
ランプスイッチバネ１７の先端１７ｂは弾性を有してお
る。The tip 17b of the lamp switch spring 17 has elasticity.
今、ランプＭＡバネ１４の１４ａ部が回路基板１１のマ
イナス極と電気的導通が取られているとする。Now, it is assumed that a portion 14a of the lamp MA spring 14 is electrically connected to the negative pole of the circuit board 11.
一方ケース（図示せず）上のプッシュボタン２２（２点
鎖線で図示してある）がプラスになっているとすれば前
記プッシュボタン２２がランプスイッチバネ１７の１７
ａ部と接すれば、ランプ１３は点灯する。On the other hand, if the push button 22 (indicated by a two-dot chain line) on the case (not shown) is positive, then the push button 22 is at 17 of the lamp switch spring 17.
When it comes into contact with part a, the lamp 13 lights up.
以上詳述した如く、ランプ接点バネ及びランプスイッチ
バネをセル支持枠に固定して一体化し、かつ各々の部材
の一部を弾性部材にしておけば、セル支持枠を組立でた
だけで簡単に回路基板との電気的導通が取れ、又、ラン
プが切れた時もセル支持枠を交換するだけで良く、実用
上多犬の効果を有する。As detailed above, if the lamp contact spring and the lamp switch spring are fixed to the cell support frame and integrated, and some of the members are made of elastic members, it is easy to assemble the cell support frame. Electrical continuity with the circuit board can be established, and even when the lamp burns out, it is only necessary to replace the cell support frame, which has many practical effects.
