- FIG. 26 is a schematic perspective view for explaining the driving mechanism of the hands of the electronic timepiece 10 according to the present invention.
- the rotational power extracted by the rotor 21 inserted into the opening in the motor stator 20 shown in the figure is the fifth wheel 22, the fourth wheel 23, the third wheel 24, the central wheel 25, and the sun wheel 26. These are transmitted to the hour wheel 27 while being decelerated through the gears.
- the hour hand 11 is fixed to the hour wheel 27, the minute hand 12 is fixed to the central wheel 25, and the second hand 13 is fixed to the fourth wheel 23.

- the upper teeth 27a are attached integrally with the cylindrical portion 27c of the hour wheel 27, and the lower teeth 27b are attached so as to rotate integrally with the cylindrical portion 27c by a spring mechanism 27d. When the winding stem 28 is rotated by this mechanism, the upper teeth 27a are rotated.
- the hour hand 11 is rotated in conjunction with the rotation, whereas the cylindrical portion 27c and the lower teeth 27b are separated by elastic deformation of the spring mechanism 27d. Therefore, since the minute wheel 26 does not rotate, the rotation of the winding stem 28 and the rotation of the minute hand 12 and the second hand 13 are not interlocked. By such a mechanism, a time adjustment operation for rotating only the hour hand 11 independently of the minute hand 12 and the second hand 13 is realized.

- 202-7 is the timepiece of the clock
- 202-8 is the hour character
- 202-9 is the "1" area of the subdivision area

- the 24 o'clock position of the hour hand 203 should be originally “3” and “4”. However, even if the interval between “2” and “3” corresponds to the 24 o'clock position of the pointer due to the accuracy of the stylus, the interval between “2” and “3” is set at the 24 o'clock position of the pointer in the processing inside the watch. It may be stored so as to correspond to. By performing such processing, high styling accuracy is not required, and the styling process can be simplified and the cost can be reduced accordingly.
- This association is performed by setting a dedicated mode for storing data corresponding to the 24 o'clock position in a storage area (not shown) in the watch when the hour hand 203 is attached. This association is essentially only performed at the time of needle attachment, but may be performed each time when a pointer deviation due to impact or the like occurs.

That is, the entire system of the present invention is characterized by the decode circuit 1 and the hand position information circuit 2, and a general clock microcomputer system can be used for the other parts.
- the hand position information circuit 2 is activated by the CPU 3 in a time difference correction mode in which the hour hand 203 moves at a high speed. In other states such as the normal use state, the hour hand 203 moves at a low speed or is stopped, and the hand position information circuit 2 is stopped. While the needle position information circuit 2 is stopped, the output of the decode circuit 1 can be directly processed by the CPU 3 without passing through the needle position information circuit 2 or through the needle position information circuit 2.
- the CPU 3 can directly process the output of the decode circuit 1 to stop the hand position information circuit 2 and the hour hand 203 can be moved at a high speed.

- the needle position information circuit 2 can be converted into “No” by converting it through an appropriate decoder (not shown). Processing is performed with values of “0”, “1” to “6”.
- region data the values “0”, “1” to “6” after the processing in the needle position information circuit 2 are referred to as region data.
- the decoding circuit 1 can be formed with a simple configuration using, for example, two contact springs and three input terminals PK1 to PK3. Of course, it is not limited to this.
- the hand position information circuit 2 holds an hour hand movement start area and a movement stop area from the hour hand detection area data input from the decoding circuit 1 according to the movement of the hour hand 203, and outputs it to the CPU 3 by a method described later.

- the stop circuit 151 is a circuit that acquires decode data (hereinafter referred to as movement stop area data) of an area where the hour hand has stopped. The stop circuit 151 continues to stop even after the start circuit 150 is activated. When the start circuit 150 acquires and stops the start area data, the stop circuit 151 is activated by the control circuit 105 to execute the stop area data acquisition operation. When the acquisition of the stop area data ends, the control circuit 105 stops the stop circuit 151.
- the start circuit 150 operates first, and the stop circuit 151 operates after the operation of the start circuit 150 ends. That is, the start circuit 150 and the stop circuit 151 each operate independently and do not operate simultaneously. This is because it is not necessary to perform the simultaneous operation due to the role of each circuit, thereby realizing low power consumption of the hand position information circuit 2.
- the timing at which the stop circuit 151 starts operation may be the same as the timing at which the start circuit 150 ends operation. In this case, since the stop circuit 151 starts operating without waiting for the end of the operation of the start circuit 150, the time until stop determination can be shortened when the hour hand movement stops immediately after the start of movement.
- the stop circuit 151 operates after the operation of the start circuit ends.

Further, it is determined whether the area data match for a predetermined time (ST4-9). If they coincide with each other for a predetermined time (ST4-9: YES), the area data is stored as a movement stop position (ST4-10), and the stop circuit stops (ST4-11).

- the stop flag circuit 119 determines that there is a possibility of a state, and generates a stop flag S19 (ST6-9). If S2 and S3 are not equal (ST6-7: NO), it is determined that the hour hand 203 is not in a stopped state but moving, S19 is not generated (ST6-8), and the process is performed again from the fetching of the area data SD of the decode circuit 1 (ST6-5).

- the CPU 3 acquires the area data of the stop position holding register 112.
- the CPU determines date feed from the area data of the start position holding register stop position holding register, and performs processing.
- the clocks S5 and S8 for taking in the register are configured to be generated only when the holding operation of the corresponding register is necessary. As a result, unnecessary clock operations are suppressed and low power consumption is achieved.
- the processing of the hand position information circuit in the first embodiment is effective when the hour hand moves in the range of “1” to “6” in the detection area.
- the “0” area is divided into “1” to “6” areas and the decode signal corresponding to each area is output, the hand position of the hour hand can be grasped at all times, Start and stop can be detected quickly.
- the purpose of this system is to determine whether or not the hour hand has crossed the 24 o'clock position, there are few merits by obtaining position information of the hour hand other than a plurality of areas before and after the 24 o'clock position.
- the areas other than the “1” to “6” areas before and after the 24 o'clock position are represented as one “0” area and represented by one decoded data.
- the direction of rotation of the hour hand is also determined even when it passes through the “0” region, stops at the “0” region, or when the “0” region is the start position. There is something that can be done.
- FIG. 9A to FIG. 9D will be used to describe problems that occur when passing through the “0” area, stopping at the “0” area, or starting at the “0” area. I will explain.
- FIG. 9A, FIG. 9B, FIG. 9C, and FIG. 9D show the difference in the area data acquired by the start position holding register 111 and the stop position holding register 112 depending on the presence / absence of the “0” area processing. Is shown.

- the hour hand detection area data and the area data of the start position holding register 111 and the stop position holding register 112 to be output to the CPU 3 are shown, and the D4 column indicates the necessity of date feeding. This necessity indicates whether or not the date feeding is originally necessary in each of the routes of “A” and “I”, and the area data of the start position holding register 111 and the stop position holding register 112. It does not indicate the result determined from.
- FIGS. 9B and 9D show the case where the above-described processing is performed on the “0” region, and FIGS. 9B and 9A, and FIGS. 9D and 9C explain the same hour hand movement pattern.

- the “0” region process is performed, so that the start position holding register value holds “6”, which is the next region of the “0” region, and stops.
- the value of the position holding register 112 holds “4”. Therefore, the CPU 3 determines the hour hand very easily depending on whether or not the region from “3” to “4” with the 24 o'clock position as a boundary is included between the start position holding register value 111 and the stop position holding register value 113. Rotation direction and date feed can be determined.
- the movement from “1” to “4” causes the date feed to cross the hour hand detection areas “3” to “4” corresponding to the 24 o'clock position.
- the movement from “6” to “4” does not correspond to the above-mentioned day feeding condition, and no date feeding is performed.
- the hour hand detection area “2” moves from “0” to “0”. Therefore, in the route “a”, “2”-“3”-“4”-“5”-“6”- The hour hand detection area changes in the order of “0”, and the hour hand detection area changes in the order of “2”-“1”-“0” in the route “A”.
- the route “a” requires a date feed to cross the 24 o'clock position, and the route “a” does not require a date feed.
- the start position holding register value is held at “2” in the route “a”, and the stop position holding register value is one of the stopped “0” areas.
- the previous area “6” is retained.
- the start position holding register value is “2”
- the stop position holding register value is the area “1” immediately before the “0” area in which the stop position holding value is stopped. Accordingly, in the case of the route “A”, the CPU 3 moves the hour hand from the detection region “2” to “6” and performs day feeding to cross the hour hand detection regions “3” to “4” corresponding to the 24 o'clock position.

- TM4 since the hour hand is in the “0” region, the first stop register 102 becomes “0”, and after one clock, the second stop register 103 also becomes “0”, and the stop flag circuit 119 becomes “1”. " Since the stop flag circuit 119 continues “1” for a certain time, it is determined that the hour hand stops. However, since the area data in the first stop register 102 is “0”, the output of the second 0-position determination circuit 121 is TM5. At the timing, the stop position selector 122 is switched to the fourth stop register 116 side, the area before moving to the “0” area is held in the stop position holding register 122, and the CPU 3 reads.

- the third stop register 115 holds the output of the first stop register 102 already synchronized with the port clock SP or the like, so the output of the decode circuit 1 operating asynchronously with the hand position information circuit 2 is held.
- metastable caused by simultaneous change of clock and data can be prevented, and the certainty of processing is further improved.
- FIG. 15 is a second modification example of FIG. 10. The difference from FIG. 10 is that the first, second, and third stop registers all operate using S8 as a clock, and the stop position selector 122 The input signal is that the first stop register 102 and the third stop register 115 are selected.
- the third stop register 115 holds the output S3 of the second stop register 103 using the output S8 of the control circuit 105 as a clock. Then, the output S 2 of the first stop register 102 and the output S 15 of the third stop register 115 are input to the stop position selector 122.
- the stop position selector 122 selects S15 if the output S21 of the second 0 position determination circuit 121 is “1”, but selects S2 if the output S21 is “0” and outputs it to the stop position holding register 112.
- the first, second, and third stop registers 102, 103, and 115 constitute a shift register, and hold the area data SD that is serially output from the decode circuit 1.
- the outputs of both the first and second stop registers 102 and 103 are compared by a stop flag circuit 119, and if they match, a stop flag S19 is generated. If this S19 continues for a certain period, the stop circuit 107 generates a stop determination S7.
- the second 0 position determination circuit 121 selects the input of the selector 122 according to whether or not the output S2 of the first stop register 102 is “0” area data. That is, when the second 0 position determination circuit 121 detects that the area data of S2 is “0” area data, the selector 122 is the area data in which the hour hand is positioned before the hour hand enters the “0” area. The output S15 of the third stop register 115 is selected, and the control circuit 105 generates S6 and takes the area data S15 into the stop position holding register 112.
- the stop position selector 122 selects S2 which is the area data where the current hour hand is located, and the control circuit 105 generates S6 and enters the stop position holding register 112.

- the input of the selector 122 may be selected according to the above. The operation is the same as that described with reference to FIG.
- FIG. 16 shows a circuit configuration of the third embodiment. The difference from FIG. 10 is that the start HR circuit 109 is not provided and the second start position holding register 113 is added.
- the CPU 3 performs processing related to timekeeping even when entering the mode for correcting the hour hand.
- the CPU 3 receives the above-described start HR signal S9 and stop HR signal S10 from the needle position information circuit 2, the CPU 3 interrupts the processing that has been performed and stores the start position holding register 111 and the stop position holding register 112 from the needle position information circuit 2. Prioritize the reading process. Therefore, in order to efficiently perform the processing of the CPU 3, it is better that the processing interruption by HR is less.
- the start HR and the stop HR are not prepared separately, but the area data of the start position holding register stop position holding register is read into the CPU 3 by the stop HR. Thereby, the processing interruption by HR is only required once, and the number of HR signal lines can be reduced.
- the second start position holding register 113 receives the output S11 of the start position holding register 111, stores the data of S11 by the output S6 of the control circuit 105, and outputs it to the CPU 3.
- S6 is a signal that causes the stop position holding register 112 to hold the stop area data of the hour hand.
- the second start position holding register 113 holds the output S11 of the start position holding register 111 at the same timing as the stop position holding register 112. To do.
- the movement start area data of the hour hand is held in the start position holding register 111.
- the movement stop area data is stored in the stop position holding register 112 when the movement stop of the hour hand is detected.
- the movement start area data is fetched from the start position holding register 111 to the second start position holding register 113 at the same timing as the holding, and the area data acquisition request signal S10 is issued from the stop HR circuit 110 to the CPU 3.
- the CPU 3 reads the data in the second start position holding register 113 and the stop position holding register 112, and performs date feeding processing. The operation is the same as that described with reference to FIG.
- the movement start area data before resuming movement is stored in the first position.
- the movement start area data at the time of re-moving can be held in the start position holding register 111 while being held in the second start position holding register 113 and transferred to the CPU 3. Therefore, even if the user moves the hour hand again when correcting the hour hand, the operation intention can be reflected and the convenience is improved. Further, not only can the number of control lines used for communication between the CPU 3 and the hour hand position information circuit be reduced, but the area data acquisition timing can be narrowed down to one, so that the processing of the CPU 3 is not interrupted. Efficiency can be improved.
- FIG. 17 is a time chart showing the time-series data flow of FIG.
- the stop position data of the hour hand is held in the stop position holding register 112 and the CPU 3 performs reading, but the data of the start position holding register 111 is transferred to the second start position holding register 113 at the same timing.
- the CPU 3 can read the data of the start position and the stop position at a time.
- FIG. 18 is an example of the stop determination circuit 107 illustrated in FIGS. 5, 10, 14, 15, and 16.
- the stop determination circuit 107 is a circuit that determines that the movement of the hour hand has stopped if the area data output from the decoding circuit does not change for a certain period.
- a timer is provided to measure the period in which the area data matches, but the timer value is provided with first timer data that is a normal determination time and second timer data that is a determination time longer than the first timer data. .
- the second timer data is selected, the time until it is determined to be stopped becomes longer. Therefore, even if the hour hand is stopped for a short time, it is not determined to be stopped, and the choke stops when the user moves the hour hand. However, it is not necessary to enter a day feeding process that is not necessary. If the calendar display is changed by the date feeding process, a lot of power is consumed. Therefore, by selecting the second timer data under the conditions described later, such as when the power supply voltage is lowered, the frequency of useless date feeding processing is reduced. It becomes possible.
- the stop determination circuit 107 stores the reset circuit 107-12, the counter 107-5, the comparator 107-6, the stop determination holding circuit 107-10, the first timer data 107-7, and the second timer data 107-8. Storage section 107-11 and selector 107-9.
- the output S6 of the stop flag circuit 119 is input to the enable of the counter 107-5 and the reset circuit 107-12, the output of the reset circuit 107-12 is input to the reset of the counter 107-5, and the output of the counter 107-5 Is input to the comparator 107-6.
- the output of the power supply voltage measurement circuit 211 is input to the CPU 3, and the date feed motor 213 is driven by a drive signal output from the CPU 3.
- the storage unit 107-11 stores the first timer data 107-7 and the second timer data 107-8, and the selector 107-9 date timer data is selected by the control signal of the CPU 3, and is sent to the comparator 107-6. Entered.
- the output of the comparator 107-6 is input to the stop determination holding circuit 107-10, and the output of the stop determination holding circuit 107-10 is output to the stop HR circuit 110, the control circuit 105, the second 0-position determination circuit 121 as S7. Is input.
- a route S8 in which the movement detection circuit 104 in FIG. 10 detects the movement of the hour hand is generated, and the first stop register 102 and the second stop register 103 hold the area data output from the decode circuit 1 serially.
- the first stop register and the second stop register are shift registers that operate with a common clock. When the position area data of the decode circuit output changes, the value of the first stop register and the second stop register is one clock. Unlikely, if there is no change, it will be the same value.
- the stop flag circuit 119 compares the first stop register 102 and the second stop register 103 and detects that the position area data match, and the stop flag S19 indicates that the stop register 1 and the second stop register have the same value. , “1” continues to be output.
- the operation of the stop determination circuit 107 will be described using the flowchart of FIG. It is determined whether S19 of the stop flag circuit is “1”, that is, whether the stop state has been reached (ST20-1). If S19 is “1” (ST20-1: YES), the counter 107-5 counts. Is executed (ST20-2).
- the specific configuration of the counter 107-5 and the clock to be counted are omitted because they are not the essential part of the present invention, but may be freely selected as long as the present invention can be realized.
- the timer value set in advance in the storage unit 107-11 is compared with the value of the counter 107-5 (ST20-3). If they become equal (ST20-3: YES), it is determined that the hour hand has stopped and S7 Is generated (ST20-4). If S19 is “0” (ST20-1: NO), the counter 107-5 is cleared by the reset circuit 107-12 and continues to be stopped (ST20-5).
- a plurality of timer setting data are prepared in the storage unit 107-11, the first timer data 107-7 sets a normal stop determination time, and the second timer data 107-8 is longer than the first timer data.
- Set the stop judgment time is, for example, 1.5 to 2 times the normal stop determination time.
- the normal stop determination time is a time suitable for stop determination obtained from the rotation speed of the hour hand during the correction operation and the clock frequency of the hand position information circuit 2.
- FIG. 21 is a flowchart showing the timer value selection process.
- the date feeding motor 212 is driven for driving the date plate (ST21-1). If the date feed motor 212 is driven (ST21-1: YES), the second timer data is selected as the timer value (ST21-4).
- the power supply voltage measurement circuit 211 determines whether or not the battery voltage is lower than the specified value (ST21-2). If the battery voltage is lower than the specified value (ST21-2: YES), the second timer data is selected as the timer value (ST21-4). Otherwise (ST21-2: NO), the first timer is used as the timer value. Data is selected (ST21-3).
- the date feeding process is performed, but it takes time to complete the date feeding operation.
- the second timer data 107-8 during the date feeding process for example, there is a re-movement of the hour hand that crosses the 24 o'clock position by a correction operation during the date feeding process. Even if the operation of the crown operation is stopped and the hour hand is stopped for a short time, the stop determination time becomes long, so that the hour hand position information circuit 107 is difficult to determine that the hour hand stops. Therefore, the frequency of receiving the start HR signal S9 and the stop HR signal S10 requesting the reading process from the hour hand position information circuit 107 during the date feeding process is reduced, and the burden on the CPU 3 can be reduced.
- the date feeding process occurs as much as the hour hand reciprocates, and time-consuming date feeding and date returning operations are unnecessarily repeated.
- the date feeding process does not react to the hour hand stop for a short time while the date feeding process is being performed. You don't have to spend
- the power supply voltage is measured by the power supply voltage measurement circuit 201, and the CPU 3 selects the second timer data even when the voltage is lower than the specified voltage.
- the pulse driving is continuously performed for the day feeding motor, and thus power is consumed. If the date feed is continuously repeated while the power supply voltage is decreasing, the voltage may further decrease and may fall below the minimum voltage at which the system operates. Therefore, while the power supply voltage is decreasing, the second timer data 107-8 is selected to increase the stop determination time, and the user reacts to an instantaneous operation stop during the hour hand operation. Avoid continuous daily feeding to the minimum necessary. As a result, the number of processes of the CPU 3 is reduced, and the power reduction can be suppressed.
- the CPU 3 may select the second timer data 107-8 while the heavy load function accompanied by the power reduction such as the hand position detection circuit 203 is operating. Or you may make it select 2nd timer data from the beginning by the setting by a user irrespective of the said conditions. In this way, it is possible to set a timer time suitable for the user's operational feeling. In this case, if three or more timer values can be selected, the user's operational feeling can be dealt with in detail.

- the start circuit output is input to the enable of the counter, and the output of the counter is input to the comparator 107-6.
- the stop flag circuit 119 is composed of a combinational circuit such as an exclusive OR, a hazard is likely to occur when the input signal is switched. If a hazard is propagated to the enable signal that controls the operation of the counter 107-5, the reliability of the counter value is lowered.
- the start signal synchronized with the clock is generated according to the ON period of the stop flag signal S19 as shown in FIG. 19 and input to the enable of the counter, so that it is not affected by the hazard of the stop flag signal. Counter malfunction can be prevented.
- the stop determination period of the stop determination circuit 107 in the hour hand position information circuit 2 is set shorter than the time required for the hour hand to pass through the “0” region. As a result, when the hour hand passes through the “0” region, a stop determination always occurs during the passage of the “0” region.

This represents the area data of the start position holding register stop position holding register.
- the stop determination time t1 is longer than the “0” region passing time, and the stop is performed within the time when the hour hand passes the “0” region. No judgment is made.
- the hour hand passes through the “0” area and stops at “6”. Therefore, the start position holding register holds “6” which is the next area of the “0” area, and the stop position holding register 112 stops.
- the area “6” is held and taken into the CPU 3. Therefore, the CPU 3 recognizes that the hour hand movement is “5” ⁇ “6”, and therefore the date advance (date return) process is not performed. That is, although the hour hand 203 straddles the 24 o'clock position, an erroneous determination that does not perform the date advance (date return) process occurs.
- the stop determination time t1 is smaller than the “0” area passing time of the hour hand, and the hour hand passes the “0” area. A stop judgment is always made during the period.

This makes it difficult to react to the time hand stop for a short period of time, and the daily feeding process can be minimized to avoid wasting power.

Abstract
Description
まず、本発明の基本原理を説明する。
図1Aは、時計の時刻表示面100-4を簡易的に示し、本発明で設定する時針判定領域を説明するものである。日付を更新する24時位置100-5の前後に特定のA領域100-1,B領域100-2を設置し、A,Bを除く領域をC領域100-3とする。
図1Bは、時針203の位置と、その位置に対応する後述のデコード回路1の出力との関係を示す対応図である。
後述の方法により、指針駆動の開始位置と停止位置に対応するデコードデータを記憶し、指針駆動停止後に両者を比較することで、24時位置の通過の有無とその方向を判断している。
次に、上記基本原理を達成するための具体的な回路構成を、図面に基づき説明する。
針位置情報回路2における開始回路150は、開始回路150の動作が許可されると(ST4-1)、定期的にデコーダ回路1から出力される領域データを取得する(ST4-2)。そして、連続して取得した時針検出領域データを比較し(ST4-3)、領域データが不一致の場合(ST4-3:NO)に、時針203が移動を開始したと認識し、移動開始時点の時針検出領域データを移動開始位置として記憶する(ST4-4)。一方、比較した領域データが変わらなければ(ST4-3:YES)、時針の移動が無いと判定し、さらに比較を続ける。
時針の移動開始を検出すると、制御回路は開始回路150を停止し(ST4-5)、続いて停止回路151の動作を許可し(ST4-6)、定期的にデコーダ回路1から領域データを取得する(ST4-7)。停止回路151では新たに読み込んだ領域データと、1サンプリング前に読み込んだ領域データとを比較し(ST4-8)、データが一致した時(ST4-8:YES)は時針203が停止したと認識し、さらに領域データが所定時間一致しているかどうかを判定する(ST4-9)。所定時間一致していれば(ST4-9:YES)、その領域データを移動停止位置として記憶して(ST4-10)、停止回路は停止する(ST4-11)。
続いて、詳細な実施形態を順次説明する。
次に図5の動作について、図6のフローチャートを用いて説明する。
第1開始レジスタ101は、CPU3から供給されるポートクロック信号SPの変化タイミングでデコード回路1から領域データSDを取得する(ST6-1)。ここでの変化タイミングとは、信号の立ち上がりエッジ、もしくは、立ち下がりエッジのいずれかを指すものとする。
また、移動開始検出を意味するS4の発生により制御回路105は、第1停止レジスタ102と第2停止レジスタ103用の動作クロックであるS8を発生させる(ST6-4)。
次に、針位置情報回路2の情報を取得するCPU3の動作を、図7に示すフローチャートにて説明する。
図8は、図5に示す針位置情報回路2の動作をタイムチャ-トにより示したものであり、図5に記した信号線の時系列なデータの流れを表している。なお、線が引かれている時間範囲は、アクティブ「1」を表し、線が引かれていない時間範囲はネガティブ「0」を表している。また、ここでは時針203が領域“1”から“4”に移動した例で説明している。
第1の実施形態における針位置情報回路の処理は、検出領域における“1”~“6”の範囲で時針が移動した場合に有効である。一方、“0”領域に対して、“1”~“6”の領域のように細かく分割して、各領域に対応するデコード信号を出力すれば、時針の針位置を常時把握でき、移動の開始と停止が速やかに検出できる。しかし、本システムの目的は時針が24時位置をまたいだかどうかの判定であるから、24時位置の前後における複数の領域以外は、時針の位置情報を得ることによるメリットは少ない。また、デコードデータの組み合わせ数が増えてしまうと、前述のように2又の接点バネと3本の入力端子PK1~3により簡単な構成で構成することができなくなり、コストと大きさの面で不利となる。従って、本実施形態では24時位置の前後の“1”~“6”領域以外は“0”領域として、1つのデコードデータで現す。
図9Aと図9BにおけるD1列の時針移動パターンは、AゾーンとBゾーンとの間で、一方から他方に移動するものである。図9Aと図9BにおけるD2列の時針移動例では、時針203が検出領域“1”から“4”に移動しており、“ア”のルートでは“1”-“2”-“3”-“4”と時針の検出領域は変わり、“イ”のルートでは“1”-“0”-“6”-“5”-“4”と時針の検出領域は変わる。“ア”のルートでは、24時位置をまたぐため日送りが必要であり、“イ”のルートでは日送り不要である。
図9Cと図9DにおけるD1列の時針移動パターンは、Aゾ-ンあるいはBゾ-ンからCゾ-ンに移動するケ-スで、“0”領域で時針が停止する場合である。
図10は、第2の実施形態における針位置情報回路2の一例を示すブロック図である。
時針の位置が“0”領域かどうか判定する回路である第1、第2の0位置判定回路120、121を開始回路150と停止回路151に設けており、“0”領域からの移動開始、“0”領域での停止を検知する。
針位置情報回路2は、図5の回路に加えて、第1の0位置判定回路120と第2の0位置判定回路121と、開始位置セレクタ130と、第3停止レジスタ115と第4停止レジスタ116と停止位置セレクタ122とを備えている。他の回路構成は同じであるので、すでに説明した同一の構成には同一の番号を付与して説明を省略する。
次に図10に示した第2の実施形態における針位置情報回路2の回路動作について、図11と図12のフローチャートを用いて説明する。図11はメインルーチンを示し、図12は開始位置の“0”領域処理の内容を示すサブルーチンを示す。
第1開始レジスタ101は、ポートクロックSDの変化タイミングでデコード回路1から出力される領域データを保持する(ST11-1)。第1開始レジスタ101の出力S1と第2停止レジスタ103の出力S3とを移動検出回路104で比較し(ST11-2)、領域データが異なっていれば(ST11-2:NO)、時針203が移動を開始したと判定してS4を発生する(ST11-3)。S1とS3が等しければ(ST11-2:YES)、時針203の移動は無いため、S1とS3の比較を続ける。ここで、第2停止レジスタ103の出力S3は、前回時針が移動して停止した時の領域データである。ここまでは、第1の実施形態と同じ動作である。
移動開始の検出を示すS4発生後、移動開始位置の“0”領域判定を行う(ST11-4)。以下、図12にて説明を行う。
再び図11に戻って、時針203の移動開始検出を示すS4の発生により、制御回路105はS8クロックを発生させ(ST11-5)、S8の変化タイミングでデコード出力1の領域データSDを第1停止レジスタ102に保持する(ST11-6)と同時に、第1停止レジスタ102の出力S2を第2停止レジスタ103で保持する(ST11-7)。
第2の0位置判定回路121は、第1停止レジスタ102の出力S2が“0”領域のデータかどうかを判定し(ST11-15)、判定信号S21を停止位置セレクタ122に入力する。停止位置セレクタ122は、S21が「1」の時に(ST11-15:YES)一つ前の検出領域データである第4停止レジスタ116の出力S16を選択し(ST11-16)、S21が「0」の時には(ST11-15:NO)、現在位置している検出領域データである第3停止レジスタ115の出力S15を選択する(ST11-17)。停止判定を示すS7発生により停止HR回路110は、S10を発生してCPU3に領域データ取得を促し(ST11-18)、CPU3は停止位置保持レジスタ112の領域データS12を取り込む(ST11-19)。CPU3は、開始位置保持レジスタ111の出力S11と停止位置保持レジスタ112の出力S12とを逐次取得して、時針が24時位置を跨いだことを判定する。
図14は、図10の変形例であり図10との違いは、第3停止レジスタ115の入力を第1停止レジスタ102の出力としている点である。このように第3停止レジスタ115が、既にポートクロックSPなどに同期化されている第1停止レジスタ102の出力を保持するので、針位置情報回路2と非同期に動作するデコード回路1の出力を保持する際に、クロックとデータが同時変化して発生するメタステ-ブルを防ぐことができ、処理の確実性が一段と向上する。
図15は、図10の第2の変形例であり、図10との違いは、第1、第2、第3停止レジスタが全てS8をクロックとして動作している点と、停止位置セレクタ122の入力信号が、第1停止レジスタ102と第3停止レジスタ115を選択している点である。
第1、第2、第3停止レジスタ102、103、115は、シフトレジスタを構成しており、シリアルにデコード回路1から出力される領域データSDを保持する。第1、第2停止レジスタ102、103の双方の出力を停止フラグ回路119で比較し、一致すれば停止フラグS19を発生する。このS19が一定期間続けば、停止回路107で停止判定S7を発生させる。
図16に第3の実施形態の回路構成を示す。図10との違いは、開始HR回路109が無く、第2の開始位置保持レジスタ113が追加されている点である。
図10に示した例では、時針の移動開始領域データを開始位置保持レジスタ111に保持するが、図16に示した例は、時針の移動停止検出により移動停止領域データを停止位置保持レジスタ112に保持するのと同じタイミングで、開始位置保持レジスタ111から第2開始位置保持レジスタ113に移動開始領域データを取り込み、停止HR回路110からCPU3に領域データの取得要求信号S10が発せられるものである。その後、CPU3は第2の開始位置保持レジスタ113と停止位置保持レジスタ112のデータを読み込み、日送り処理を行う。前記動作以外は、図10で説明した動作と同じである。この構成によって、CPU3が前記の移動開始領域データと移動停止領域データを読み込んでいる途中に、使用者の操作によって時針203の移動が再開されたとしても、移動再開前の移動開始領域データを第2の開始位置保持レジスタ113に保持してCPU3に転送しつつ、再移動時の移動開始領域データを開始位置保持レジスタ111に保持することができる。従って、ユーザが時針修正の際に時針を再移動させたとしても、操作意図を反映でき利便性が向上する。また、CPU3と時針位置情報回路との通信に使用する制御線を減らすことができるばかりではなく、領域データの取得タイミングが1つに絞られるため、CPU3の処理を小分けに中断することが無くなり、効率化を図ることが可能となる。
図18は、図5、10、14、15、16で図示した停止判定回路107の1例である。
次に図18に示された停止判定回路107の動作を説明する。ここでは、まず図10の針位置情報回路2における停止フラグ回路119の出力信号S19について説明する。
図21を用いて、記憶部107-11内の第1タイマデータ107-7と第2タイマデータ107-8の選択処理を説明する。
図19は、図18の回路の変形例である。入力S19からカウンタ回路に至る構成が図18とは異なり、停止フラグ前縁検出回路117-1と停止フラグ後縁検出回路117-2とスタート回路117-3とが追加されている。
第4の実施形態を図22で説明する。第4の実施形態は、時針位置情報回路2における停止判定回路107の停止判定期間を、時針が“0”領域通過に要する時間より短く設定するものである。これにより、時針が“0”領域を通過する場合は、“0”領域通過中に必ず停止判定が発生する。
次に動作を説明する。時針が移動し始めると、開始位置保持レジスタ111に領域”5”が保持される。時針は移動を続けて“0”領域に入ると、位置領域データがしばらく変わらないため、停止フラグ回路119はS19を発生し続ける。停止判定回路107では、停止判定時間t1が“0”領域通過時間より小さいため、“0”領域を通過中に停止判定が発生する。すると、第2の実施形態で説明した“0”領域処理により、停止位置保持レジスタ112に“0”領域の一つ前の領域である”1”が保持され、CPU3に取り込まれる。CPU3は、時針の移動が”5”→”1”の領域であるため、日送り(日戻し)処理を行う。
図23は、第4の実施形態における停止判定時間t1の設定方法を示したものである。図23は、時針の“0”領域通過の間に必ず停止判定となるように停止判定時間t1を定めるうえで、停止判定時間t1の最小値と最大値とを設定する手法を示したものであり、(a)は停止判定期間t1の最小値について、(b)は停止判定期間t1の最大値について示している。(1)は、時針の移動ルートと停止判定時間について表したものであり、(2)は、時針の移動に伴いデコード回路1から出力される領域データを、左から右に時系列に示したものである。
