Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of occurrence of a system failure and malfunction of an electronic time piece itself due to battery voltage reduction caused by a heavy load, or the malfunction of a pointer position detection function due to the malfunction of a light receiving element when the electronic time piece includes both an optical pointer position detection function and an illumination function. <P>SOLUTION: When the pointer position detection function and the illumination function are required simultaneously, the priority is given to the pointer position detection function, and the illumination function is blocked during the pointer position detection time. In particular, when the pointer position detection time comes during the illumination, the illumination is temporarily stopped and restored after completing the pointer position detection. Conversely, when the illumination time comes during the pointer position detection, the execution of the illumination is kept waiting until the completion of the pointer position detection. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、衝撃等が加わることによって表示されている時刻（指針位置）がずれた場合でも指針位置ずれの補正量に基づいて自動的に補正することが出来る指針位置検出機能付き電子時計に関する。   The present invention relates to an electronic timepiece having a pointer position detection function that can automatically correct a time (pointer position) displayed due to an impact or the like even when the displayed time (pointer position) is shifted based on a correction amount of a pointer position shift.

腕時計等のアナログ電子時計は、時刻針である時針、分針、秒針の回転位置によって現在時刻を視認することが出来る。ところで、このようなアナログ電子時計は、衝撃等が加わった場合において、内部の駆動モータであるステップモータが一定のステップで回転せずにどちらかの方向に複数ステップ回転し、指針（特に秒針）の位置が時計内で設定される基準時刻の位置とずれることがある。   An analog electronic timepiece such as a wristwatch can visually recognize the current time according to the rotational positions of the hour hand, the minute hand, and the second hand, which are time hands. By the way, in the case of such an analog electronic timepiece, when an impact or the like is applied, a step motor as an internal drive motor does not rotate in a fixed step but rotates in a plurality of steps in either direction, and a pointer (particularly a second hand) May deviate from the position of the reference time set in the watch.

このため、従来より、衝撃等が加わった場合などにおいて、指針位置がずれているか否かを検出するための透過光学式の指針位置検出手段を備えた電子時計が提案されている（例えば、特許文献１参照）。以下、図面に基づいて特許文献１より、従来の指針位置検出機能を有する電子時計を説明する。   For this reason, conventionally, there has been proposed an electronic timepiece equipped with a transmission optical type pointer position detecting means for detecting whether or not the pointer position is shifted when an impact or the like is applied (for example, a patent) Reference 1). Hereinafter, a conventional electronic timepiece having a hand position detecting function will be described from Patent Document 1 with reference to the drawings.

図４は、特許文献１に開示された従来の指針位置検出機能を有する電子時計の構造を示すものであって、特許文献１の内容をモディファイした断面図である。１は秒針ステップモータのロータであり、該ロータ１は５番車２を介して秒針車３を駆動し、文字板４の外側で該秒針車３に嵌合された秒針（図示せず）を駆動する。前記５番車２と前記秒針車３には前記ロータ１の６０ステップに１回だけ重なる透過孔２１と透過孔３１がそれぞれ設けられている。
また、５は赤外線等を発光する発光素子で第１の基板６１上に実装され、７は前記発光素子５からの光を受光する為の受光素子で第２の基板６２上に実装されており、前記５番車２の透過孔２１と前記秒針車３の透過孔３１が重なったときに、前記発光素子５からの光を受光するような位置に対向して配置されている。
８、９はそれぞれ前記ロータ１を駆動するためのコイル、ステータであり、１０は前記ロータ１や５番車２や秒針車３を受けるための輪列受けで、１１は前記ロータ１や５番車２を受けるための地板で、前記輪列受け１０と対向して配置される。 FIG. 4 is a cross-sectional view showing the structure of a conventional electronic timepiece having a function of detecting a hand position disclosed in Patent Document 1, and is a modified sectional view of the contents of Patent Document 1. Reference numeral 1 denotes a rotor of a second hand step motor. The rotor 1 drives a second hand wheel 3 via a fifth wheel 2 and a second hand (not shown) fitted to the second hand wheel 3 on the outside of the dial 4. To drive. The fifth wheel 2 and the second hand wheel 3 are each provided with a transmission hole 21 and a transmission hole 31 that overlap only once with 60 steps of the rotor 1.
Reference numeral 5 denotes a light emitting element that emits infrared rays or the like, and is mounted on the first substrate 61. Reference numeral 7 denotes a light receiving element for receiving light from the light emitting element 5, which is mounted on the second substrate 62. When the transmission hole 21 of the fifth wheel 2 and the transmission hole 31 of the second hand wheel 3 overlap with each other, they are arranged to face each other so as to receive light from the light emitting element 5.
8 and 9 are coils and stators for driving the rotor 1, respectively, 10 is a wheel train receiver for receiving the rotor 1, the fifth wheel 2 and the second hand wheel 3, and 11 is the rotor 1 and the fifth wheel. A base plate for receiving the vehicle 2 and disposed opposite the train wheel receiver 10.

指針位置検出機能は、時計制御用の集積回路（図示せず）にて例えば６０秒分カウントされる毎に前記発光素子５を駆動し、前記透過孔２１と前記透過孔３１を通して前記受光素子７が受光を検出した場合、前記秒針はずれることなく正しい位置にあると判断する。逆に、前記受光素子７が受光を検出しなかった場合、前記秒針はずれた位置にあると判断し、ずれの補正量に基づいて自動的に前記秒針位置を補正する。
特開昭６１−１１８６８３号公報 The pointer position detection function drives the light emitting element 5 every time it is counted for 60 seconds by an integrated circuit for clock control (not shown), for example, and passes through the transmission hole 21 and the transmission hole 31 to receive the light receiving element 7. When the received light is detected, it is determined that the second hand is in a correct position without being displaced. Conversely, if the light receiving element 7 does not detect light reception, it is determined that the second hand is in a shifted position, and the second hand position is automatically corrected based on the correction amount of the shift.

ところで、最近では指針表示によるアナログ電子時計においても照明を備えるものが多くなってきている。また、指針表示と液晶表示素子等のデジタル表示を併用するコンビネーション電子時計においては、照明の具備は周知慣用の技術である。コンビネーション電子時計においては、デジタル表示にＬＥＤや可視光有機ＥＬデバイスなどの自発光デバイスを使用することも多くなってきている。   By the way, recently, there are an increasing number of analog electronic timepieces that are provided with illumination. Further, in a combination electronic timepiece using both a pointer display and a digital display such as a liquid crystal display element, the provision of illumination is a well-known and commonly used technique. In combination electronic timepieces, self-luminous devices such as LEDs and visible light organic EL devices are often used for digital display.

しかしながらこのような照明付き、もしくは発光機能付きの指針表示式電子時計におい
て、透過光学式の指針位置検出を導入する場合、以下のような問題を有していた。 However, when such a pointer display type electronic timepiece with illumination or light emission function is introduced, the following problems have been encountered when introducing transmission optical type pointer position detection.

すなわち、透過光学式の指針位置検出を実現する場合、発光素子（多くは赤外ＬＥＤ）を使用するため、照明駆動時に指針位置検出を実行すると、時計にとって重負荷である発光素子が複数同時に駆動されるため、電池電圧の著しい低下を招き、システムダウンや時計自体の誤動作、あるいは受光素子（多くはフォトトランジスタ）の誤動作による指針位置検出の誤動作を引き起こす恐れがある。   That is, when realizing transmission optical type pointer position detection, light emitting elements (mostly infrared LEDs) are used. Therefore, when pointer position detection is performed during illumination driving, a plurality of light emitting elements, which are heavy loads for the watch, are driven simultaneously. As a result, the battery voltage is significantly reduced, and there is a risk of malfunction of the pointer position detection due to system down, malfunction of the watch itself, or malfunction of the light receiving element (mostly phototransistor).

また、指針位置検出は、歯車の透過孔を通過した発光素子の光を受光素子が検出することで行われるが、その際に照明が駆動されると、照明光により非透過位置でも受光素子が誤って受光し、その結果指針位置がずれた状態に補正されてしまう恐れがある。   The pointer position is detected by the light receiving element detecting the light of the light emitting element that has passed through the transmission hole of the gear. When the illumination is driven at that time, the light receiving element is detected even at the non-transmissive position by the illumination light. There is a possibility that the light is erroneously received and, as a result, the pointer position is corrected to be shifted.

本発明の目的は上記問題点を解決し、指針表示式電子時計において、発光機能と指針位置検出機能を両立させることが出来る技術を提供することである。   An object of the present invention is to solve the above-described problems and provide a technique capable of achieving both a light emitting function and a pointer position detecting function in a pointer display type electronic timepiece.

上記課題を解決するために、本発明の指針位置検出機能付き電子時計は、下記記載の構成を採用する。   In order to solve the above problems, the electronic timepiece with a pointer position detection function of the present invention employs the following configuration.

指示部材と、該指示部材を駆動する指示部材駆動手段と、前記指示部材以外の重負荷を駆動する重負荷駆動手段と、前記指示部材の位置を検出する指示部材位置検出装置と、前記重負荷駆動手段、前記指示部材駆動手段および前記指示部材位置検出装置の駆動を制御する制御手段とを備え、該制御手段は、前記重負荷駆動手段と前記指示部材位置検出装置の同時駆動を禁止することを特徴とする。   An indicating member, an indicating member driving means for driving the indicating member, a heavy load driving means for driving a heavy load other than the indicating member, an indicating member position detecting device for detecting the position of the indicating member, and the heavy load Drive means, control means for controlling the indication member position detection device, and control means for controlling the drive of the indication member position detection device, the control means prohibiting simultaneous driving of the heavy load drive means and the indication member position detection device. It is characterized by.

これにより、時計にとっての重負荷が緩和され、電池電圧の著しい低下を招くことが無くなるため、時計自体の安定動作が保たれ、且つ指針位置検出を正確に実行出来る。   As a result, the heavy load on the timepiece is alleviated and the battery voltage is not significantly reduced, so that the stable operation of the timepiece itself can be maintained and the pointer position detection can be performed accurately.

また、前記制御手段は、前記重負荷駆動手段の駆動中に前記指示部材位置検出装置の駆動タイミングとなった場合、前記重負荷駆動手段を停止し、前記指示部材位置検出装置の駆動を実行することを特徴とする。   Further, the control means stops the heavy load driving means and executes driving of the pointing member position detecting device when the driving timing of the pointing member position detecting device is reached during driving of the heavy load driving means. It is characterized by that.

これにより、時計にとっての重負荷を緩和しつつ、指針位置検出を優先して実行出来る。   As a result, the hand position detection can be prioritized and executed while alleviating the heavy load on the watch.

また、前記制御手段は、前記指示部材位置検出装置の駆動終了後、前記重負荷駆動手段の駆動を再開することを特徴とする。   Further, the control means restarts the driving of the heavy load driving means after the end of driving of the pointing member position detecting device.

これにより、時計にとっての重負荷を緩和しつつ、重負荷機能を自動復帰させることで使い勝手を良くすることが出来る。   As a result, ease of use can be improved by automatically returning the heavy load function while alleviating the heavy load on the watch.

また、前記制御手段は、前記指示部材位置検出装置の駆動中に前記重負荷駆動手段の駆動タイミングとなった場合、前記指示部材位置検出装置の駆動終了まで前記重負荷駆動手段の駆動を待機し、前記指示部材位置検出装置の駆動終了後に前記重負荷駆動手段の駆動を実行することを特徴とする。   The control means waits for driving of the heavy load driving means until the end of driving of the pointing member position detecting device when the driving timing of the heavy load driving means comes during driving of the pointing member position detecting apparatus. The driving of the heavy load driving means is performed after the end of driving of the pointing member position detecting device.

これにより、時計にとっての重負荷を緩和しつつ、指針位置検出を優先して実行出来ると共に、指針位置検出終了後、重負荷機能を速やかに実行させることで使い勝手を良くすることが出来る。   As a result, it is possible to preferentially execute the hand position detection while alleviating the heavy load on the timepiece, and improve the usability by promptly executing the heavy load function after the end of the hand position detection.

また、前記重負荷が第１の発光素子であり、前記重負荷駆動手段が前記第１の発光素子を駆動する発光素子駆動手段であり、前記指示部材位置検出装置は、前記第１の発光素子とは異なる第２の発光素子と、該第２の発光素子から照射される光を検出する受光素子を含む光学式指示部材位置検出装置であることを特徴とする。   Further, the heavy load is a first light emitting element, the heavy load driving means is a light emitting element driving means for driving the first light emitting element, and the pointing member position detecting device includes the first light emitting element. An optical pointing member position detection device including a second light emitting element different from the above and a light receiving element for detecting light emitted from the second light emitting element.

これにより、発光機能と指針位置検出機能を両方備えることが出来る。
また、光学式指針位置検出実行時に発光することが無いので、発光機能動作による光学式指針位置検出の誤動作を防止することが出来る。 Thereby, both a light emission function and a pointer position detection function can be provided.
Further, since no light is emitted when the optical pointer position detection is executed, it is possible to prevent malfunction of the optical pointer position detection due to the light emitting function operation.

また、前記第１の発光素子が電子時計の表示面を照明する照明手段であることを特徴とする。   Further, the first light emitting element is illumination means for illuminating the display surface of the electronic timepiece.

これにより、発光機能と指針位置検出機能を両方備えることが出来る。   Thereby, both a light emission function and a pointer position detection function can be provided.

また、前記表示手段として、液晶表示素子を有することを特徴とする。   The display means includes a liquid crystal display element.

これにより、発光機能と指針位置検出機能を両方備えたコンビネーション電子時計を実現することが出来る。   As a result, a combination electronic timepiece having both a light emitting function and a pointer position detecting function can be realized.

また、前記第１ならびに第２の発光素子が自発光表示素子であることを特徴とする。   The first and second light emitting elements are self-luminous display elements.

これにより、有機ＥＬデバイスといった視認性の良い発光機能を備えることが出来る。   Thereby, a light-emitting function with good visibility such as an organic EL device can be provided.

上記の如く本発明によれば、指針表示式電子時計において、発光機能と指針位置検出機能を両立させることが出来る技術を提供出来る。   As described above, according to the present invention, it is possible to provide a technique capable of making the light emission function and the pointer position detection function compatible in the pointer display type electronic timepiece.

次に、図２に基づいて本発明の一実施形態を説明する。尚、従来例の図４と同じ部分は同じ符号を付して説明を省略する。   Next, an embodiment of the present invention will be described with reference to FIG. The same parts as those in the conventional example shown in FIG.

図２において、１２は照明用の発光素子であり、例えば可視光ＬＥＤ等からなる。６３
は前記発光素子１２が実装される第３の基板である。また、１３は前記第３の基板に重ねて配置される液晶表示素子である。 In FIG. 2, reference numeral 12 denotes a light emitting element for illumination, which includes, for example, a visible light LED. 63
Is a third substrate on which the light emitting element 12 is mounted. Reference numeral 13 denotes a liquid crystal display element disposed on the third substrate.

次に、図３(ａ)、図５（ａ）に基づいて本発明の第１の実施形態による動作を説明する。
第１実施例は、照明実行中に指針位置検出のタイミングになった場合の例である。 Next, the operation according to the first embodiment of the present invention will be described with reference to FIGS. 3 (a) and 5 (a).
The first embodiment is an example when the timing for detecting the pointer position is reached during the execution of illumination.

図３(ａ)は、前記制御手段１０１による指針位置検出機能と照明機能の制御フローの一例である。まず、指針位置検出機能付き電子時計の通常運針状態中に指針位置検出制御が開始される（Ｓ１）。ここで例えば、６０秒に１回の前記発光素子５と前記受光素子７を駆動する指針位置検出タイミングであれば（Ｓ２）、前記重負荷１０５である照明用の発光素子１２が点灯中かを判断する（Ｓ３）。指針位置検出タイミングでなければ通常運針状態を継続する。照明点灯中であれば、前記発光素子５と前記受光素子７の駆動からなる指針位置検出機能と前記照明用の発光素子１２の同時駆動を禁止するため前記照明を中断し（Ｓ４）、前記指針位置検出機能を優先して実行する（Ｓ５）。指針位置検出機能を実行後、照明中断中であったか判断し（Ｓ６）、中断中であれば該照明の駆動を再開する（Ｓ７）。   FIG. 3A is an example of a control flow of the pointer position detection function and the illumination function by the control means 101. First, the pointer position detection control is started during the normal hand movement state of the electronic timepiece with the pointer position detection function (S1). Here, for example, if it is the pointer position detection timing for driving the light-emitting element 5 and the light-receiving element 7 once every 60 seconds (S2), it is determined whether the light-emitting element 12 for illumination that is the heavy load 105 is being lit. Judgment is made (S3). If it is not the pointer position detection timing, the normal hand movement state is continued. If the illumination is on, the illumination is interrupted in order to prohibit simultaneous operation of the pointer position detection function including driving of the light emitting element 5 and the light receiving element 7 and the illumination light emitting element 12 (S4), and the pointer The position detection function is prioritized and executed (S5). After executing the pointer position detection function, it is determined whether the illumination has been interrupted (S6), and if it has been interrupted, the driving of the illumination is resumed (S7).

尚、指針位置検出機能は、前記発光素子５と前記受光素子７の駆動が約２ｍｓ程度の極めて短い時間で実行されるため、その間に照明を中断しても人間の視覚的には全く影響を与えることはない。   The pointer position detection function is executed in a very short time of about 2 ms because the light emitting element 5 and the light receiving element 7 are driven. Therefore, even if the illumination is interrupted during that time, there is no visual impact on humans. Never give.

次に、図３(ｂ) 、図５（ｂ）に基づいて本発明の第２の実施形態による動作を説明する。
第２実施例は、指針位置検出実行中に、外部操作などにより、照明実行タイミングになった場合の例である。 Next, the operation according to the second embodiment of the present invention will be described with reference to FIGS. 3 (b) and 5 (b).
The second embodiment is an example when the illumination execution timing comes due to an external operation or the like during execution of the pointer position detection.

図３(ｂ)は、前記制御手段１０１による指針位置検出機能と照明機能の制御フローの第二の例である。まず、例えば、ユーザのボタン操作等により照明点灯制御が開始される（Ｓ８）。ここで、指針位置検出機能が実行中であれば（Ｓ９）、前記照明を点灯させることなく待機する。前記指針位置検出機能が実行終了すれば、前記照明の点灯を開始する（Ｓ１０）。   FIG. 3B is a second example of the control flow of the pointer position detection function and the illumination function by the control means 101. First, for example, illumination lighting control is started by a user button operation or the like (S8). Here, if the pointer position detection function is being executed (S9), the process waits without turning on the illumination. When the execution of the pointer position detection function is completed, the lighting of the illumination is started (S10).

尚、指針位置検出機能は、前記発光素子５と前記受光素子７の駆動が約２ｍｓ程度の極めて短い時間で実行されるため、その間照明を待機して遅らせても人間の視覚的には全く影響を与えることはない。   The pointer position detection function is executed in a very short time of about 2 ms because the light emitting element 5 and the light receiving element 7 are driven. Therefore, even if the illumination is waited and delayed during that time, it is completely unaffected by human vision. Never give.

尚、指針位置検出機能を備えたアナログ電子時計機能に、液晶表示素子を追加したコンビネーション電子とすることで、時刻だけでなくカレンダやクロノ等様々な機能を付加した多機能な電子時計を提供することが出来る。   In addition, by using a combination electronic with a liquid crystal display element added to an analog electronic timepiece function with a pointer position detection function, a multi-function electronic timepiece is provided in which not only the time but also various functions such as calendar and chrono are added. I can do it.

また、可視光ＬＥＤや有機ＥＬデバイス等の自発光表示素子を備えることで、視認性に優れた使い勝手の良い電子時計を提供することが出来る。   In addition, by providing a self-luminous display element such as a visible light LED or an organic EL device, an easy-to-use electronic timepiece having excellent visibility can be provided.

以上のように、本発明によれば光学式の指針位置検出機能と照明機能を両方備えた場合でも、重負荷による電池電圧低下に伴う時計自体のシステムダウンや誤動作、あるいは受光素子の誤動作による指針位置検出機能の誤動作がなく、安定した時計動作や機能を提供することが可能となる。   As described above, according to the present invention, even when both the optical pointer position detection function and the illumination function are provided, the pointer itself is caused by a system down or malfunction due to a battery voltage drop due to heavy load, or a malfunction of the light receiving element. There is no malfunction of the position detection function, and it is possible to provide stable clock operations and functions.
