Description

以上の課題を解決するため、本発明に係る電子時計の一態様は、第１の情報を指示する第１の表示針と、駆動源からの駆動力を前記第１の表示針に伝える動力伝達機構と、前記第１の表示針の回転軸と同軸の回転により第２の情報を指示する第２の表示針と、前記第１の表示針の回転を減速して前記第２の表示針を回転させる減速機構と、前記第１の表示針により前記第１の情報が指示される領域であって、前記同軸を中心とする中心角がθ１である第１の表示領域と、前記第２の表示針により前記第２の情報が表示される領域であって、前記同軸における角度ｄθによって複数の表示単位に分割された第２の表示領域と、を備え、前記減速機構の減速比を１／Ｎとしたときに、ｄθ＞θ１／Ｎの関係が満たされることを特徴とする。 To solve the above problems, one embodiment of an electronic timepiece according to the present invention, a power transmission for transmitting a first display hands for indicating the first information, the driving force from the driving source to the first display hands mechanism and the the rotation of the rotary shaft and the axis of the first display hand and the second display hands for indicating the second information, the first said decelerating the rotation of the display hand in the second display hands A first speed reduction mechanism for rotating the first display area, a first display area in which the first information is indicated by the first display needle, the central angle about the coaxial axis being θ1, and the second display area. And a second display area divided into a plurality of display units by the angle dθ on the same axis , and the reduction ratio of the reduction mechanism is 1 When / N, the relationship of dθ> θ1 / N is satisfied.

本発明に係る電子時計の他の態様は、第１の情報を指示する第１の表示針と、駆動源からの駆動力を前記第１の表示針に伝える動力伝達機構と、前記第１の表示針の回転軸と同軸で回転する回転板と、前記第１の表示針の回転を減速して前記回転板を回転させる減速機構と、前記第１の表示針により前記第１の情報が指示され、前記同軸を中心とする中心角がθ１である第１の表示領域を含む文字板とを備え、前記文字板には開口部が形成され、前記回転板には、当該回転板が回転すると前記開口部から視認可能な位置に前記第２の情報が表示され、前記同軸における角度ｄθによって複数の表示単位に分割された第２の表示領域と、を備え、前記減速機構の減速比を１／Ｎとしたときに、ｄθ＞θ１／Ｎの関係が満たされることを特徴とする。
この態様によれば、第１の表示針がθ１だけ振れたとしても、回転板はθ１／Ｎだけ振れることになる。ここで、ｄθ＞θ１／Ｎとなるので、仮に、第１の表示針がθ１だけ回転しても、第２の表示領域における表示単位の角度ｄθ未満となる。よって、第１の表示針が指示する第１の情報が変更された場合に、第２の情報の誤読を低減することができる。 Another aspect of the electronic timepiece according to the present invention includes a first display hands for indicating the first information, and a power transmission mechanism for transmitting the driving force from the driving source to the first display hand, the first a rotating plate which rotates at the rotational axis and the axis of the display hands, the rotation speed reduction mechanism which decelerates rotation of the rotating plate of the first display hand, the first information by the first display needle And a dial including a first display area having a center angle of θ1 centered on the coaxial axis , the dial having an opening, and the rotating plate rotating the rotating plate. Then, the second information is displayed at a position that is visible from the opening, and a second display area that is divided into a plurality of display units by the angle dθ on the coaxial line , and the reduction ratio of the reduction mechanism is When 1 / N, the relationship of dθ> θ1 / N is satisfied.
According to this aspect, even if the first indicator hand swings by θ1, the rotating plate swings by θ1 / N. Here, since dθ> θ1 / N, even if the first display hand is rotated by θ1, it is less than the display unit angle dθ in the second display area. Therefore, when the first information indicated by the first display hand is changed, misreading of the second information can be reduced.

図３は、第１の表示針４１の回転範囲と連動する第２の表示針４２の回転範囲を示している。図示の例で第２の表示針４２は、表示単位４４ａを指し示している。第２の表示針４２が表示単位４４ａに位置する場合、表示モードは時刻表示を行うＴＩＭＥモードとなる。このＴＩＭＥモードでは、時刻表示に加え、クロノグラフ機能（ストップウォッチ）が有効となる。そして、ボタン１３を押下するとセンターの計測表示針１１が１／５秒刻みで運針を開始し、同時に６時情報表示部４の第１の表示針４１が電池残量のＦを示す位置から５４°右回転し、"ＭＥＡＳ"位置を示す。このとき、第２の表示針４２は第１の表示針４１の回転に連動して４．５°右に回転する。"ＴＩＭＥ"の表示単位４４ａは、３０°の幅を持っている。従って、第２の表示針４２は"ＴＩＭＥ"の表示単位４４ａの内にある。同様に、電池残量のＦを示す位置から５４°左回転し、第１の表示針４１が電池残量"Ｅ"を指し示す場合、第２の表示針４２は４．５°左回転するが、"ＴＩＭＥ"の表示単位４４ａの内にある。 FIG. 3 shows the rotation range of the second display hand 42 that is linked with the rotation range of the first display hand 41. In the illustrated example, the second display hand 42 points to the display unit 44a. If the second display hand 4 2 is positioned on the display unit 44a, the display mode is a TIME mode for time display. In the TIME mode, in addition to the time display, the chronograph function (stopwatch) is enabled. When the button 13 is pressed, the center measurement display hand 11 starts to move in 1/5 second increments, and at the same time, the first display hand 41 of the 6 o'clock information display unit 4 starts from a position indicating F of the remaining battery level. ° Turn right to indicate "MEAS" position. At this time, the second indicator hand 42 rotates to the right by 4.5 ° in conjunction with the rotation of the first indicator hand 41. The display unit 44a of “TIME” has a width of 30 °. Accordingly, the second indicator hand 42 is within the “TIME” display unit 44a. Similarly, when the battery indicator F is turned 54 ° to the left from the position indicating F and the first indicator hand 41 indicates the battery level “E”, the second indicator hand 42 is turned 4.5 ° counterclockwise. , "TIME" display unit 44a.
