Description

  The present invention relates to an electronic timepiece that displays a date and time using a rotary display.

  2. Description of the Related Art Conventionally, there are electronic timepieces that can display the current time using a pointer (rotating display) such as an hour hand or a minute hand. Some electronic timepieces can switch and display the current time and information other than the current time using a rotary display. For example, Patent Document 1 discloses a technique for displaying a radio wave reception state by rotating a second hand. In addition, there are electronic clocks that can switch and display local time in cities and regions around the world, alarm setting time, remaining time related to the timer function, counting time related to the stopwatch function, and the like.

Thus, when switching the information to be displayed by the rotation display body, the rotation display body is fast-forwarded and rotated at a higher speed than the rotation operation at the time of displaying the current time, and moved to the position related to the information display after the switching. Is done.
Further, this fast-forward rotation operation can be executed not only when the information to be displayed is switched, but also when the current time displayed by the rotary display body is corrected.

JP 2004-226350 A

  However, the user of the electronic timepiece cannot obtain desired information from the electronic timepiece while the rotary display body is rotating fast forward. Since the amount of rotation in the fast-forward rotation operation varies each time depending on the information displayed after switching and the position of the rotation display body before the fast-forward rotation operation starts, the user of the electronic timepiece waits until the desired information is obtained. There is a problem that time cannot be assumed.

(First embodiment)
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a first embodiment of the invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an internal configuration of an electronic timepiece according to an embodiment of the present invention.

  The electronic timepiece 1 of the present embodiment includes a date wheel 2, an hour hand 3, a minute hand 4, a second hand 5 (hereinafter, the date wheel 2 to the second hand 5 are collectively referred to as hands 2 to 5 (rotating display)), A first stepping motor 32 that rotates the date wheel 2 through a train wheel mechanism 22 in which a plurality of gears are arranged, a hour hand 3 through a train wheel mechanism 23, and a wheel train mechanism 24. A second stepping motor 33 that rotates the minute hand 4 and a third stepping motor 35 that rotates the second hand 5 via the train wheel mechanism 25 (hereinafter, the first stepping motor 32, the second stepping motor 33, and the third stepping). The motor 35 is also collectively referred to as stepping motors 32, 33, and 35), a drive circuit 39 that outputs drive pulses to the stepping motors 32, 33, and 35, and a CPU (Central Processing Unit) 4 (Control means), ROM (Read Only Memory) 42, RAM (Random Access Memory) 43, power supply unit 44, operation unit 45, oscillation circuit 46, frequency divider circuit 47, clock circuit 48, An antenna 49 and a standard radio wave receiver 50 are provided.

  The hour hand 3, the minute hand 4, and the second hand 5 are all pointers having a normal hand shape, and are arranged so as to be rotatable with respect to the same rotation axis on the dial and indicate one direction. The hour hand 3, the minute hand 4, and the second hand 5 can have any thickness or decorative shape as long as the pointing direction can be easily read. On the other hand, the date wheel 2 is an annular (disk-shaped) pointer, and is arranged so as to be rotatable around the rotation shaft at the lower part of the dial. On the upper surface of the date indicator 2, date signs representing dates “1” to “31” are sequentially provided on the peripheral portion thereof. By rotating the date indicator 2, a small transmission mark provided on the dial is provided. Any one date indicator is selectively exposed from the window (window). The transmission small window may be covered with a transparent member such as glass or acrylic resin.

  Each of the gear train mechanisms 22 to 25 has a configuration in which a plurality of gears mesh with each other and rotate at a predetermined gear ratio, and the last gear in each of the gear train mechanisms 22 to 25 is a stepping connected to each gear train mechanism. In conjunction with the step rotation of the motors 32, 33, and 35, a rotation operation of a predetermined angle is transmitted to the date wheel 2, hour hand 3, minute hand 4, and second hand 5, respectively, thereby indicating a desired position (rotation position). . The gear train mechanism 23 includes a plurality of gears that rotate in conjunction with the rotation of an intermediate gear (intermediate wheel) of the gear train mechanism 24, and the gear rotates at a gear ratio different from the gear ratio of the gear of the gear train mechanism 24. It is supposed to be. As a result, the train wheel mechanism 23 and the train wheel mechanism 24 transmit rotation operations at different angles to the hour hand 3 and the minute hand 4 in conjunction with the step rotation of the second stepping motor 33.

The first stepping motor 32 is driven (step-driven) by each of a plurality of drive pulses input from the drive circuit 39 at a predetermined time of the day, for example, 24:00, and the rotor rotates 180 degrees stepwise. The date indicator is advanced by one day by rotating the date indicator 2 by a plurality of step rotation operations corresponding to the driving pulse.
The second stepping motor 33 is driven by a drive pulse inputted once every 10 seconds from the drive circuit 39, the rotor rotates 180 degrees stepwise, rotates the minute hand 4 once per step, and the hour hand 3 1 Rotate 1/12 degrees per step. Therefore, the minute hand 4 makes one round in 360 steps (1 hour), and the hour hand 3 makes one round in 4320 steps (12 hours).
The third stepping motor 35 is driven by a drive pulse input once per second from the drive circuit 39, so that the rotor rotates by 180 degrees and the second hand 5 is rotated by 6 degrees per step. Accordingly, the second hand 5 makes one round in 60 steps (1 minute).
The pointers 2 to 5 can be fast-forwarded and rotated at 16 pps (pulse per second), 24 pps, and 32 pps in the forward direction and the reverse direction, respectively.

  The drive circuit 39 outputs a drive pulse of a predetermined voltage to the stepping motors 32, 33, and 35 in accordance with a control signal from the CPU 41 to rotate the rotor of the stepping motors 32, 33, and 35 once at a predetermined angle (180 degrees in this embodiment). Step rotation is performed.

  There is play (backlash) between the plurality of gears constituting each of the gear train mechanisms 22 to 25. Accordingly, when the rotation direction of the hands 2 to 5 is switched between the forward rotation direction and the reverse rotation direction, the step train motors 32 to 33 are rotated while the stepping motors 32, 33, and 35 are rotated a predetermined number of times (the number of idling steps). The intermediate gears are idle, and the pointers 2 to 5 are not rotated.

  In the electronic timepiece 1 of the present embodiment, when moving the pointer in the reverse direction, the stepping motor performs the reverse rotation operation for the number of idle steps or the number of steps beyond that (reverse step number). In order to eliminate the idling associated with the rotation in the forward rotation direction, it is necessary to perform a swing-back operation that causes the stepping motor to perform the forward rotation operation. The number of reversing steps is different for each of the hands 2 to 5, and among them, the number of reversing steps related to the hour hand 3 (hereinafter referred to as the number of hour hand reversing steps) is the number of reversing steps related to the minute hand 4 (hereinafter referred to as the number of reversing steps). This is larger than the minute hand swing back step number). Accordingly, when the hour hand 3 and the minute hand 4 that have been moved in the forward rotation direction are moved in the reverse rotation direction, the hour hand 3 and the minute hand 4 in the period in which the number of steps to reversely rotate the second stepping motor 33 is equal to or less than the number of minute hand swing back steps. Both the minute hand 4 is not rotated, and only the minute hand 4 is rotated in the reverse direction during a period greater than the number of minute hand swingback steps and less than the number of hour hand swingback steps, while the hour hand 3 and the minute hand are rotated during a period greater than the number of hour hand swingback steps. 4 are rotated in the reverse direction. The number of swingback steps related to the pointers 2 to 5 is stored in advance in the ROM 42 and read out during the swingback operation.

The CPU 41 performs various arithmetic processes in the electronic timepiece 1 and performs overall control of the entire operation.
The ROM 42 stores various control programs executed by the CPU 41 and setting data. In the setting data, the number of steps for reversing according to the pointers 2 to 5, the time difference from Coordinated Universal Time (UTC) relating to cities and / or regions in the world, and daylight saving time information are stored.
The RAM 43 is a volatile memory that provides a working memory space to the CPU 41 and stores programs, temporary data, and the like read from the ROM 42 and expanded. The temporary data stored in the RAM 43 includes current time data (hour, minute, second) counted by the time counting circuit 48, hour / minute hand current position data (0 to 4319) indicating the current positions of the hour hand 3 and the minute hand 4, and a second hand 5 Second hand current position data (0 to 59) indicating the current position of the hand, hour / minute hand rotation direction data (0: forward rotation, 1: reverse rotation) indicating the rotation direction in the rotating operation of the hour hand 3 and the minute hand 4, hour hand 3, minute hand to be described later Hour / minute hand set position data (0-4319) indicating the position of the movement destination of the hour hand 3 and minute hand 4 in the fast-forward rotation operation of the 4 and second hand 5, and second hand set position data indicating the position of the movement destination of the second hand 5 in the fast-forward rotation operation (0 to 59), the number of movement steps of the hour hand 3 and the minute hand 4 in the entire rapid feed rotation operation, and the remaining number of movement steps of the hour hand 3 and the minute hand 4 in the rapid feed rotation operation are included. In addition, the RAM 43 stores an alarm time related to an alarm time setting mode, which will be described later, a timer setting time related to the timer mode, and a setting value related to each rotation speed of the hands 2 to 5.

  The power supply unit 44 supplies power to each unit of the electronic timepiece 1 via the CPU 41. The power supply unit 44 is not particularly limited. For example, a combination of a solar cell and a secondary battery enables continuous power supply for a long time.

The operation unit 45 includes an external operation switch such as a push button crown, receives operations such as pressing and rotation by the user, converts them into electrical signals, and outputs them to the CPU 41.
The operation unit 45 and the CPU 41 can acquire the time data by the standard radio wave receiving unit 50 and correct the display time by the hands 2 to 5 according to the acquisition result in response to an operation on the operation unit 45 by the user. It is like that.
Further, the operation unit 45 and the CPU 41 can set the operation mode of the electronic timepiece 1 to any one of a plurality of operation modes in accordance with the operation of the operation unit 45 by the user. The operation mode of the electronic timepiece 1 is not particularly limited, but in addition to the normal time display mode, the world time mode for displaying the world time, the alarm time setting mode for setting the alarm time, the timer mode, There is a stopwatch mode.
Of these, in the world time mode, cities or regions of the world are designated by the user's operation on the operation unit 45, and the date and time counted by the timing circuit based on the time difference and daylight saving time information relating to the designated city or region are appropriate. The time is converted, and the display indicating the converted local time is made by the pointers 2 to 5. In the alarm time setting mode, the alarm time designated by the user's operation on the operation unit 45 is displayed by the hands 2 to 5 and stored in the RAM 43. In the timer mode, the timer setting time designated by the user's operation on the operation unit 45 is displayed by the pointers 2 to 5 and stored in the RAM 43, and when an operation related to the start of the timer operation is performed, the operation starts from the timer setting time. The remaining time obtained by subtracting the elapsed time after the start is displayed by the pointers 2 to 5. In the stopwatch mode, when the hands 2 to 5 are moved to the position of 0: 0: 0 and an operation related to the start of the operation of the stopwatch is performed, an indication of the elapsed time after the start of the operation is displayed by the hands 2 to 5 Done.

  The oscillation circuit 46 oscillates and outputs a predetermined frequency signal. The frequency dividing circuit 47 divides the frequency signal input from the oscillation circuit 46 to generate and output a signal of each frequency used in the electronic timepiece 1. The time counting circuit 48 counts the number of times a signal having a predetermined frequency (for example, 1 Hz) output from the frequency dividing circuit 47 is input, and adds it to time data to hold the current time.

  The standard radio wave receiver 50 uses the antenna 49 to receive a standard radio wave in which time information is encoded and transmitted by radio waves in a long wavelength band, and demodulates and decodes the encoded signal (time code). It outputs to CPU41. The tuning frequency to the long wavelength band radio wave by the standard radio wave receiver 50 is adjusted according to the transmission frequency from the standard radio wave transmission station to be received under the control of the CPU 41. The time data acquired from the decoded time code is sent from the CPU 41 to the timer circuit 48 and overwritten, whereby the current time data is overwritten and corrected.

Next, the fast forward rotation operation of the hour hand 3, the minute hand 4, and the second hand 5 will be described.
In the electronic timepiece 1 of the present embodiment, for example, in a state where the accurate time is not displayed due to the battery being exhausted, the battery is replaced, and time data is acquired by the standard radio wave receiving unit 50 according to an operation on the operation unit 45 by the user. In this case, the hour hand 3, the minute hand 4 and the second hand 5 are moved to a position indicating an accurate current time by performing a fast-forward rotating operation in which the hour hand 3, the second hand 5 and the second hand 5 are rotated at a higher speed than the normal time display.
Further, in the electronic timepiece 1, when the operation mode of the electronic timepiece 1 is changed, the hour hand 3, the minute hand 4 and the second hand 5 are fast-forwarded and rotated, and the hour hand 3, The minute hand 4 and the second hand 5 are moved. Here, the positions of the hour hand 3, the minute hand 4, and the second hand 5 in the changed operation mode are positions related to the time in the specified city in the world time mode, and the latest stored in the RAM 43 in the alarm time setting mode. In the timer mode, the position is related to the latest timer setting time stored in the RAM 43. In the stopwatch mode, the position is 0 hour, 0 minute, 0 second.
Further, the rotation direction in the fast-forward rotation operation related to the hour hand 3 and the minute hand 4 is set to a direction in which the rotation amount in the fast-forward rotation operation is reduced.

In this embodiment, when the fast feed rotation operation of the hour hand 3, the minute hand 4 and the second hand 5 is performed, first, the rotation amount of the hour hand 3 and the minute hand 4 related to the entire fast feed rotation operation (hereinafter also referred to as the hour / minute hand fast feed rotation amount). A preliminary operation is performed in which the hour hand 3 and the minute hand 4 are rotated in the direction opposite to the rotation direction in the fast-forward rotation operation by the rotation amount corresponding to the rotation amount, and then rotated by the same rotation amount in the rotation direction in the fast-forward rotation operation and returned to the original position. Done. In the present embodiment, the amount of rotation of the hour hand 3 and the minute hand 4 in each rotation direction in this preliminary operation is 30 steps (5 minutes) when the hour / minute hand rapid feed rotation amount is 359 steps or less (corresponding to less than 1 hour). If the hour / minute hand rapid feed rotation amount is 360 steps or more and 719 steps or less (corresponding to 1 hour or more and less than 2 hours), it is 60 steps (corresponding to 10 minutes), and the hour / minute hand rapid feed rotation amount is When it is 720 steps or more (corresponding to 2 hours or more), it is 90 steps (corresponding to 15 minutes). In the present embodiment, an operation combining the fast-forward rotation operation of the hour hand 3, the minute hand 4, and the second hand 5 and the above-described preliminary operation is referred to as a fast-forward operation. Further, the control for performing the preliminary operation corresponds to the rotation amount information display control.
After the preliminary operation is completed, the hour hand 3 and the minute hand 4 are fast-forwarded and rotated. Here, the rotation speed in the fast-forward rotation operation is set in accordance with the remaining amount of the hour / minute hand rapid-feed rotation amount, that is, the amount obtained by subtracting the rotation amount in the performed fast-forward rotation operation from the entire rotation amount of the fast-forward rotation operation. . In this embodiment, the rotational speed in the fast-forward rotation operation is 32 pps when the remaining amount of hour / minute hand rapid feed rotation amount is 360 steps or more (corresponding to one hour or more), and the remaining amount of hour / minute hand rapid feed rotation amount is It is 24 pps when it is 180 steps or more and 359 steps or less (corresponding to 30 minutes or more and less than 1 hour), and 16 pps when the remaining amount of the hour / minute hand rapid feed rotation amount is 179 steps or less (corresponding to less than 30 minutes) It is.
As described above, in the electronic timepiece 1 of the present embodiment, the hour hand 3 and the minute hand 4 are rotated in the reverse direction to the fast feed rotation operation by the rotation amount corresponding to the hour / minute hand fast feed rotation amount in the preliminary operation. As the rotational speed of the minute hand 4 in the fast-forward rotation operation gradually decreases in accordance with the remaining amount of the hour / minute hand fast-forward rotation amount, information (rotation amount information) related to the rotation amount in the fast-forward rotation operation can be transmitted to the user.

  FIG. 2 is a diagram for explaining an example of a fast-forward operation executed in the electronic timepiece 1. In FIG. 2, in the state where 7:23:40 is displayed, time data indicating 9: 41: 8, which is the correct current time, is acquired by the standard radio wave receiver 50, and the hour hand 3, the minute hand 4, and the second hand The operation until 5 is moved to the current time position is shown.

FIG. 2A is a diagram showing the positions of the hour hand 3, the minute hand 4, and the second hand 5 at the time of starting the fast-forwarding operation.
When the fast-forward operation is started, the second hand 5 is fast-forwarded and rotated in the forward direction at a speed of 32 pps, and is moved to the position of “8 seconds” that is the destination of the fast-forward rotation operation (FIG. 2B). .
Next, since the hour / minute hand rapid feed rotation amount is 720 steps or more (2 hours or more), the hour hand 3 and the minute hand 4 are rotated in the reverse direction at a speed of 32 pps by 90 steps (15 minutes) (FIG. 2 (c)). )) After that, a preliminary operation is performed in which the rotational operation (FIG. 2D) is performed in the forward rotation direction at a speed of 32 pps for 90 steps.
Next, a fast-forward rotation operation in the forward direction of the hour hand 3 and the minute hand 4 is executed. That is, first, when the hour hand 3 and the minute hand 4 are rotated at a speed of 32 pps, and the remaining amount of the hour / minute hand rapid feed rotation amount is less than 359 steps (FIG. 2 (e)), the rotation speed is changed to 24pps, When the remaining amount of rotation is less than 179 steps (FIG. 2 (f)), the rotation speed is changed to 16pps. Thereafter, the hour hand 3 and the minute hand 4 are fast-forwarded and rotated to a position of 9:41 according to the current time at a rotational speed of 16 pps (FIG. 2 (g)).
The second hand 5 may be moved in the same manner as in a normal time display operation after being moved to the position of “8 seconds” as shown in FIG.

  Next, a fast-forward process related to a fast-forward operation in the electronic timepiece 1 of the present embodiment will be described.

  FIG. 3 is a flowchart showing a control procedure by the CPU 41 for fast-forward processing.

  This fast-forwarding process is performed when the hour hand 3 and the minute hand 4 are moved in accordance with the overwriting correction of the time data by the standard radio wave receiving unit 50 and the CPU 41 according to the operation by the user or when the operation mode of the electronic timepiece 1 is changed. Called and executed when the pointed position is changed from the current position.

  When the fast-forward process is started, the CPU 41 first stores various data related to the fast-forward process to be executed in the RAM 43 (step S101). That is, the CPU 41 causes the RAM 43 to store hour / minute hand set position data and second hand set position data indicating the positions to which the hour hand 3, minute hand 4 and second hand 5 are moved in the fast-forward operation. Further, the CPU 41 specifies the rotation directions of the hour hand 3 and the minute hand 4 using the hour / minute hand set position data and the second hand set position data, the hour / minute hand current position data and the second hand current position data, and obtains the hour / minute hand rotation direction data. It is stored in the RAM 43. Further, the CPU 41 calculates the number of movement steps and stores it in the RAM 43.

  The CPU 41 causes the second hand 5 to rotate fast forward to the second hand set position indicated by the second hand set position data (step S102). That is, the CPU 41 causes the drive circuit 39 to output the number of drive pulses corresponding to the difference between the second hand set position data and the second hand current position data to the stepping motor 35 to rotate the second hand 5 at a speed of 32 pps. Move to the set position.

  The CPU 41 determines whether or not the rotation direction in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 is the forward rotation direction (that is, whether or not the hour / minute hand rotation direction data is 0) (step S103). When it is determined that the rotation direction in the fast-forward rotation operation is the normal rotation direction (“Yes” in step S103), the CPU 41 executes the forward rotation fast-forward pre-processing to perform the above-described preliminary operation (step S104). ). Details of the forward rotation fast forward pre-processing will be described later.

  The CPU 41 substitutes the value of the movement step number for the remaining movement step number and stores it in the RAM 43 (step S105).

  The CPU 41 executes a fast feed speed setting process for setting the rotation speed in the fast feed rotation operation of the hour hand 3 and the minute hand 4 (step S106). Details of the fast-forward speed setting process will be described later.

  The CPU 41 causes the drive circuit 39 to output a drive pulse to the stepping motor 33 to move the hour hand 3 and the minute hand 4 by one step in the forward rotation direction (step S107).

The CPU 41 determines whether or not the remaining number of steps is 0 (step S108). If it is determined that the number of remaining steps is not 0 (“No” in step S108), the CPU 41 shifts the process to step S106. The CPU 41 repeats the processing from step S106 to step S108 until the remaining number of steps becomes zero, thereby causing the hour hand 3 and the minute hand 4 to perform a fast-forward rotation operation in the forward direction. Here, the CPU 41 controls the execution timing of step S107 so that the speed of the fast-forward rotation operation becomes the rotation speed (any one of 32 pps, 24 pps, and 16 pps) set in the fast-forward speed setting process for each repetition.
If it is determined that the remaining number of steps is 0 (“Yes” in step S108), the CPU 41 ends the fast-forward process.

  In step S103, when it is determined that the rotation direction in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 is the reverse rotation direction ("No" in step S103), the CPU 41 executes the reverse rotation rapid feed pre-processing and described above. A preliminary operation is performed (step S109). The details of the reverse fast-forward preprocessing will be described later.

  When the reverse rotation fast feed processing is completed, the CPU 41 causes the drive circuit 39 to output a drive pulse for rotating the rotor in the reverse rotation direction by the number of minute hand swing back steps to the stepping motor 33 at a speed of 32 pps. Among them, the gears up to the minute hand 4 are made free of play with respect to the rotation operation in the reverse rotation direction (step S110). Hereinafter, the same processing as step S110 is also referred to as processing for bringing the gears up to the minute hand 4 to the reverse side.

  The CPU 41 substitutes the value of the moving step number for the remaining moving step number and stores it in the RAM 43 (step S111).

  CPU41 performs the rapid feed speed setting process which sets the rotational speed in the rapid feed rotation operation of the hour hand 3 and the minute hand 4 (step S112). This fast-forward speed setting process is the same process as step S106.

  The CPU 41 causes the drive circuit 39 to output a drive pulse to move the hour hand 3 and the minute hand 4 one step in the reverse direction (step S113).

  The CPU 41 determines whether or not the remaining number of steps is 0 (step S114). If it is determined that the number of remaining steps is not 0 (“No” in step S114), the CPU 41 shifts the processing to step S112. The CPU 41 repeatedly performs the processing from step S112 to S114 until the remaining number of steps becomes zero, thereby causing the hour hand 3 and the minute hand 4 to perform fast-forward rotation in the reverse direction. Here, the CPU 41 controls the execution timing of step S113 so that the speed of the fast-forward rotation operation becomes the rotation speed (any one of 32 pps, 24 pps, and 16 pps) set in the fast-forward speed setting process for each repetition.

If it is determined that the number of remaining steps is 0 (“Yes” in step S114), the CPU 41 subtracts the minute hand swing back step number from the hour hand swing back step number for the stepping motor 33 by the drive circuit 39. The drive pulse for rotating the rotor in the reverse rotation direction by the number of steps is output at a speed of 32 pps, and then the drive pulse for rotating the rotor in the forward rotation direction by the number of hour hand swing back steps is output at a speed of 32 pps. The gears related to the hour hand 3 and the minute hand 4 of the mechanisms 23 and 24 are made free of play in the normal rotation direction (the gears are moved toward the normal rotation side) (step S115).
When the process of step S115 ends, the CPU 41 ends the fast-forward process.

  FIG. 4 is a flowchart showing a control procedure by the CPU 41 for forward rotation fast-forward preprocessing.

  When the forward rotation rapid feed pre-processing is started, the CPU 41 determines whether or not the value of the hour / minute hand set position data is larger than the value of the hour / minute hand current position data (step S201). When it is determined that the value of the hour / minute hand set position data is larger than the value of the hour / minute hand current position data (“Yes” in step S201), the CPU 41 calculates the hour from the value of the hour / minute hand set position data. A value obtained by subtracting the value of the minute hand current position data is substituted and stored in the RAM 43 (step S202). When it is determined that the value of the hour / minute hand set position data is equal to or smaller than the value of the hour / minute hand current position data (“No” in step S201), the CPU 41 sets the hour / minute hand set position data to the number of movement steps. The value obtained by adding 4320 to the value and subtracting the value of the hour / minute hand current position data is substituted and stored in the RAM 43 (step S203).

  When the process of step S202 or step S203 is completed, the CPU 41 performs a process of moving the gears up to the minute hand 4 to the reverse side (step S204).

  The CPU 41 determines whether the number of movement steps is 359 or less, 360 or more and 719 or less, and 720 or more (step S205). If the number of movement steps is 359 or less, the drive circuit 39 causes the stepping motor 33 to be determined. On the other hand, a driving pulse for rotating the rotor in the reverse rotation direction is output to rotate the hour hand 3 and the minute hand 4 in the reverse rotation direction for 30 steps (step S206). On the other hand, when the moving step number is 360 or more and 719 or less, the CPU 41 rotates the hour hand 3 and the minute hand 4 in the reverse direction of 60 steps (step S207). If the number of movement steps is 720 or more, the CPU 41 rotates and moves the hour hand 3 and the minute hand 4 in the reverse direction of 90 steps (step S208). The rotational speeds of the hour hand 3 and the minute hand 4 in steps S206 to S208 are 32 pps.

  The CPU 41 causes the drive circuit 39 to output a driving pulse for rotating the rotor in the forward rotation direction by the number of minute hand swingback steps to the stepping motor 33 at a speed of 32 pps, and to the minute hand 4 of the wheel train mechanisms 23 and 24. The gear is made free of play in the forward rotation direction (step S209). Hereinafter, the same processing as that in step S209 is also referred to as processing for bringing the gears up to the minute hand 4 to the forward rotation side.

  The CPU 41 determines whether or not a predetermined standby time has elapsed after the end of step S209 (step S210). The process of step S210 is performed based on the output of a counter circuit (not shown), and the predetermined standby time is set to a time sufficient for the user to recognize the stop of the minute hand 4, for example, 1 second. If it is determined that the predetermined standby time has not elapsed ("No" in step S210), the CPU 41 executes the process of step S210 again.

When it is determined that the predetermined standby time has elapsed (“Yes” in step S210), the CPU 41 determines whether the number of movement steps is 359 or less, 360 or more and 719 or less, or 720 or more. (Step S211). When it is determined that the number of movement steps is 359 or less, the CPU 41 outputs a driving pulse for rotating the rotor in the normal rotation direction to the stepping motor 33 by the driving circuit 39 to move the hour hand 3 and the minute hand 4. Rotate 30 steps in the forward rotation direction (step S212). If it is determined that the number of movement steps is 360 or more and 719 or less, the CPU 41 rotates and moves the hour hand 3 and the minute hand 4 in the forward rotation direction by 60 steps (step S213). If it is determined that the number of movement steps is 720 or more, the CPU 41 rotates and moves the hour hand 3 and the minute hand 4 in the forward rotation direction of 90 steps (step S214). The rotational speed of the hour hand 3 and the minute hand 4 in steps S212 to S214 is 32 pps.
When any of the processes in steps S212 to S214 ends, the CPU 41 ends the forward rotation fast-forward pre-processing.

  FIG. 5 is a flowchart showing a control procedure by the CPU 41 of the reverse fast-forward preprocessing.

  When the reverse rotation rapid feed pre-processing is started, the CPU 41 determines whether or not the value of the hour / minute hand set position data is larger than the value of the hour / minute hand current position data (step S301). When it is determined that the value of the hour / minute hand set position data is larger than the value of the hour / minute hand current position data (“Yes” in step S301), the CPU 41 sets 4320 to the value of the hour / minute hand current position data. And the value obtained by subtracting the value of the hour / minute hand set position data is substituted and stored in the RAM 43 (step S302). When it is determined that the value of the hour / minute hand set position data is equal to or less than the value of the hour / minute hand current position data (“No” in step S301), the CPU 41 sets the hour / minute hand current position data to the number of movement steps. A value obtained by subtracting the value of the hour / minute hand set position data from the value is substituted and stored in the RAM 43 (step S303).

  When the process of step S302 or step S303 ends, the CPU 41 determines whether the number of movement steps is 359 or less, 360 or more and 719 or less, and 720 or more (step S305), and steps S306 to S306 are performed according to the determination result. One of the processes of S308 is performed. The processes in steps S306 to S308 are the same as the processes in steps S206 to S208 of the forward rotation fast-forward process, except that the rotation direction in the rotation operation of the hour hand 3 and the minute hand 4 is the forward rotation direction. Omitted.

  The CPU 41 performs a process of moving the gears up to the minute hand 4 to the reverse side (step S309), and determines whether or not a predetermined waiting time has elapsed after the end of step S309 (step S310). The process of step S310 is the same as the process of step S210.

The CPU 41 determines whether the number of moving steps is 359 or less, 360 or more and 719 or less, or 720 or more (step S311), and performs any one of steps S312 to S314 according to the determination result. The processes in steps S312 to S314 are the same as the processes in steps S212 to S214 of the forward rotation fast-forward process, except that the rotation direction in the rotation operation of the hour hand 3 and the minute hand 4 is the reverse rotation direction, and thus description thereof is omitted. To do.
In the processes of steps S312 to S314, since the play of the gears related to the hour hand 3 remains at the start of these processes, the rotation amount in the rotating operation of the hour hand 3 is determined from the number of hour hand swing back steps. Although the number of steps obtained by subtracting the number of minute hand swing back steps is insufficient, this shortage is compensated by the operation of rotating the rotor of the stepping motor 33 in the above-described step S115 in the reverse rotation direction.

When any of the processes in steps 312 to S314 is completed, the CPU 41 performs a process of bringing the gears up to the minute hand 4 to the forward rotation side (step S315). Note that when the processing of step S315 and step S110 performed next to step S315 is performed, the gears of the gear train mechanisms 23 and 24 return to the state before the start of step S315, so that steps S315 and S110 are performed. This process can be omitted.
When the process of step S315 ends, the CPU 41 ends the pre-reverse fast-forward preprocessing.

  FIG. 6 is a flowchart showing a control procedure by the CPU 41 of the fast-forward speed setting process.

  When the fast-forward speed setting process is started, the CPU 41 substitutes a value obtained by subtracting 1 from the remaining moving step number for the remaining moving step number, and stores it in the RAM 43 (step S401).

The CPU 41 determines whether the remaining movement step number is 179 or less, 180 or more and 359 or less, and 360 or more (step S402). If the remaining movement step number is 179 or less, the hour hand 3 and the minute hand 4 Is set to 16 pps (hereinafter referred to as hour / minute hand rapid feed speed) (step S403), and when the remaining moving step number is 180 or more and 359 or less, the hour / minute hand rapid feed speed is set to 24 pps. (Step S404) If the number of remaining moving steps is 360 or more, the hour / minute hand rapid feed speed is set to 32 pps (Step S405) and stored in the RAM 43, respectively.
When any one of steps S403 to S405 is completed, the CPU 41 ends the fast-forward speed setting process.

  As described above, the electronic timepiece 1 according to the present embodiment includes the hour hand 3, the minute hand 4, the second hand 5, and the CPU 41. The CPU 41 controls the rotation operation of the hour hand 3, the minute hand 4, and the second hand 5, and the hour hand 3 When the minute hand 4 is caused to perform a fast feed rotation operation, rotation amount information relating to the rotation amount in the fast feed rotation operation is based on hour / minute hand set position data indicating the position of the movement destination of the hour hand 3 and the minute hand 4 by the fast feed rotation operation. Is rotated by the hour hand 3 and the minute hand 4. According to such a configuration, the rotation operation of the hour hand 3 and the minute hand 4 can easily indicate information related to the rotation amount in the fast-forward rotation operation of the hour hand 3 and the minute hand 4. As a result, the user who cannot know in advance the position of the hour hand 3 and the minute hand 4 at the end of the fast-forward rotation operation and the amount of rotation in the fast-forward rotation operation, the waiting time until the end of the fast-forward rotation operation, that is, desired information from the electronic timepiece 1 is obtained. It is possible to assume a waiting time until the user is obtained and to improve user convenience.

  Further, in the rotation amount information display control, the CPU 41 rotates the hour hand 3 and the minute hand 4 for performing the fast feed rotation operation according to the rotation amount in the fast feed rotation operation before starting the fast feed rotation operation (control). means). According to this, information on the rotation amount in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 can be indicated by the rotation amount of the hour hand 3 and the minute hand 4 before the start of the fast-forward rotation operation.

  Further, the rotation operation of the hour hand 3 and the minute hand 4 according to the rotation amount in the fast-forward rotation operation is performed so that the rotation direction in the rotation operation is opposite to the rotation direction in the fast-forward rotation operation. Thereby, the information regarding the rotation amount in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 can be shown more easily by the rotation amount in the rotation operation in the reverse direction of the hour hand 3 and the minute hand 4 which are easy to catch the eyes of the user.

  Further, in the rotation amount information display control, the CPU 41 gradually decreases the speed of the rotation operation of the hour hand 3 and the minute hand 4 performing the fast feed rotation operation in accordance with the remaining rotation amount in the fast feed rotation operation (control unit). According to this, information on the remaining rotation amount in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 can be shown in an intuitively easy-to-understand manner by changing the rotation speed of the hour hand 3 and the minute hand 4.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. In the fast-forwarding operation according to the second embodiment, the fast-forwarding rotation operation of the hour hand 3 and the minute hand 4 is performed, and the ratio of the rotation amount related to the fast-forwarding rotation operation that has been performed with respect to the hour-minute hand fast-forwarding rotation amount is indicated by the second hand 5. The second embodiment is different from the first embodiment in that the preliminary operation by the hour hand 3 and the minute hand 4 is not performed, and the hour-minute hand rapid feed speed is constant. Hereinafter, differences from the first embodiment will be mainly described.

FIG. 7 is a diagram for explaining an example of the fast-forward operation according to the second embodiment.
FIG. 7A is a diagram showing the positions of the hour hand 3, the minute hand 4, and the second hand 5 at the time of starting the fast-forward operation.
When the fast-forwarding operation is started, the second hand 5 is rotated at the position of “0 second” at 32 pps in the forward rotation direction (FIG. 7B).
Next, the fast feed rotation operation of the hour hand 3 and the minute hand 4 is started (FIG. 7C). The speed of this fast-forward rotation operation is 32 pps. Further, the second hand 5 indicates the ratio of the rotation amount in the fast-forward rotation operation that has already been performed among the rotation amounts of the entire fast-forward rotation operation of the hour hand 3 and the minute hand 4 with 1 turn of the second hand 5 as 1 by the indicated position of the second hand. It is rotated. That is, the second hand 5 is rotated in the forward rotation direction together with the hour hand 3 and the minute hand 4, and when the quarter of the fast-forward rotation operation is performed and the hour hand 3 and the minute hand 4 are moved to the position of 7:57, The second hand 5 is moved to a position of “15 seconds” corresponding to a quarter turn (FIG. 7D). Further, at the time when 1/2 of the fast-forward rotation operation is performed and the hour hand 3 and the minute hand 4 are moved to the position of 8:32, the second hand 5 is positioned at “30 seconds” corresponding to 1/2 turn. (FIG. 7E). Further, when 3/4 of the fast-forward rotation operation is performed and the hour hand 3 and the minute hand 4 are moved to the position of 9: 6, the second hand 5 is positioned at “45 seconds” corresponding to 3/4 round. (Fig. 7 (f)). Then, when the hour hand 3 and the minute hand 4 are rotated to the position of 9:41, which is the movement destination position in the fast-forwarding operation, the second hand 5 makes one round from the start of the fast-forwarding operation, and the position of “0 second”. (Fig. 7 (g)). Thereafter, the second hand 5 is fast-forwarded and rotated at a speed of 32 pps and is moved to the “8 second” position related to the second hand setting position (FIG. 7H).

In the second embodiment, the RAM 43 stores the number of moved steps of the hour hand 3 and the minute hand 4 in the fast forward rotation operation of the hour hand 3 and the minute hand 4, and the hour / minute hand fast forward rotation based on the number of the moved steps and the number of moved steps. The ratio of the rotation amount related to the fast-forward rotation operation that has been performed with respect to the amount is calculated.
It should be noted that the second hand 5 is accompanied by the fast feed rotation of the hour hand 3 and the minute hand 4 so that the ratio of the rotation amount in the unexecuted fast feed rotation operation to the rotation amount of the entire fast feed rotation operation of the hour hand 3 and the minute hand 4 is indicated by the second hand 5. May be rotated so as to make one turn in the reverse direction.
Further, in the second embodiment, the control for indicating the ratio of the rotation amount related to the fast-forward rotation operation that has been performed with respect to the hour / minute hand fast-forward rotation amount by the second hand 5 corresponds to the rotation amount information display control.

  Next, the fast-forward process of the hands in the electronic timepiece 1 of the second embodiment will be described.

  FIG. 8 is a flowchart showing a control procedure by the CPU 41 of the fast-forward process according to the second embodiment.

  When the fast-forward process is started, the CPU 41 first stores various data related to the fast-forward process to be executed in the RAM 43 (step S501). The process in step S501 is the same as the process in step S101 related to the fast-forward process in the first embodiment.

  The CPU 41 causes the drive circuit 39 to output the number of drive pulses corresponding to the second hand current position data to the stepping motor 35 to rotate the second hand 5 at a speed of 32 pps and move it to the position of “0 second” (step) S502).

  The CPU 41 determines whether or not the rotation direction in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 is the forward rotation direction (that is, whether or not the hour / minute hand rotation direction data is 0) (step S503). If it is determined that the rotation direction in the fast-forward rotation operation is the normal rotation direction (“Yes” in step S503), the CPU 41 assigns 0 to the number of moved steps and stores it in the RAM 43 (step S504).

  The CPU 41 causes the drive circuit 39 to output a drive pulse to the stepping motor 33 to move the hour hand 3 and the minute hand 4 by one step in the forward rotation direction (step S505).

  When the process of step S505 is completed, the CPU 41 executes a progress status display process for displaying the progress status of the fast-forward rotation operation of the hour hand 3 and the minute hand 4 by the second hand 5 (step S506). Details of the progress status display processing will be described later.

  The CPU 41 determines whether or not the number of moved steps is equal to the number of moved steps (step S507). When it is determined that the number of moved steps is different from the number of moved steps (“No” in step S507), the CPU 41 shifts the process to step S505. The CPU 41 repeats the processing from step S505 to S507 until the number of moved steps equals the number of moving steps, thereby causing the hour hand 3 and the minute hand 4 to perform a fast-forward rotation operation in the forward rotation direction. Here, the CPU 41 controls the execution timing of step S505 so that the speed of the fast-forward rotation operation is 32 pps.

  If it is determined in step S503 that the rotation direction in the fast-forward rotation operation is the reverse rotation direction ("No" in step S503), the CPU 41 performs a process of bringing the gears up to the minute hand 4 to the reverse rotation side (step S508). ).

  The CPU 41 assigns 0 to the number of moved steps and stores it in the RAM 43 (step S509).

  The CPU 41 causes the drive circuit 39 to output a drive pulse to the stepping motor 33 to move the hour hand 3 and the minute hand 4 one step in the reverse direction (step S510).

  When the process of step S510 ends, the CPU 41 executes a progress status display process (step S511). The process in step S511 is the same as the process in step S506.

  The CPU 41 determines whether or not the number of moved steps is equal to the number of moved steps (step S512). When it is determined that the number of moved steps is different from the number of moved steps (“No” in step S512), the CPU 41 shifts the process to step S510. The CPU 41 repeatedly executes the processing from step S510 to S512 until the number of moved steps equals the number of moved steps, thereby causing the hour hand 3 and the minute hand 4 to perform a fast-forward rotation operation in the reverse direction. Here, the CPU 41 controls the execution timing of step S510 so that the speed of the fast-forward rotation operation is 32 pps.

  When it is determined that the number of moved steps is equal to the number of moving steps (“Yes” in step S512), the CPU 41 performs a process of moving the gears related to the hour hand 3 and the minute hand 4 to the forward rotation side (step S513). .

After the processing of step S513 is completed, or when it is determined in step S507 that the number of moved steps is equal to the number of movement steps (“Yes” in step S507), the CPU 41 sets the second hand 5 based on the second hand set position data. It is moved to the indicated second hand setting position (step S514). That is, the CPU 41 causes the drive circuit 39 to output the number of drive pulses corresponding to the difference between the second hand set position data and the second hand current position data to the stepping motor 35 to rotate the second hand 5 at a speed of 32 pps. Move to the second hand set position.
When the process of step S514 ends, the CPU 41 ends the fast-forward process.

  FIG. 9 is a flowchart showing a control procedure by the CPU 41 of the progress status display process.

  When the progress status display process is started, the CPU 41 substitutes the number obtained by adding 1 to the number of moved steps and stores the number in the RAM 43 (step S601).

The CPU 41 moves the second hand 5 to a position represented by mod (int ((number of moved steps / number of moving steps) × 60), 60) (step S602). Here, when a and b are real numbers, mod (a, b) represents a remainder when a is divided by b when 0 ≦ a, and (a + b) when a <0. Represents the remainder when. Int (a) represents the integer part of a. When the calculated position and the second hand current position data are different from each other, the CPU 41 causes the drive circuit 39 to output a drive pulse to the stepping motor 35 to rotate the second hand 5 to thereby calculate the calculated position. Move to.
If the position of the second hand 5 at the start of the process in step S602 is equal to the position calculated as described above, the CPU 41 ends the process in step S602 without moving the second hand 5.
When the process of step S602 ends, the CPU 41 ends the progress status display process.

  As described above, the electronic timepiece 1 according to the second embodiment includes a plurality of rotation display bodies (the hour hand 3, the minute hand 4, and the second hand 5), and the CPU 41 performs the fast-forward rotation operation in the rotation amount information display control. 3 and the second hand 5 different from the minute hand 4 are caused to perform a rotation operation indicating rotation amount information (control means). Thereby, the information regarding the remaining rotation amount in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 can be indicated by the second hand without affecting the fast-forward rotation operation of the hour hand 3 and the minute hand 4.

  Further, in the rotation amount information display control, the CPU 41 causes the second hand 5 to perform a rotation operation according to the ratio of the rotation amount in the fast-forward rotation operation that has already been performed to the rotation amount in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 ( Control means). Thereby, the progress status of the fast-forward rotation operation of the hour hand 3 and the minute hand 4 can be intuitively shown.

(Modification)
Next, a modification of the second embodiment will be described. The fast-forwarding operation according to the present modification is different from the second embodiment in that the hour hand 3 and the minute hand 4 are fast-forwarded and the remaining time of the fast-forwarding rotational operation is indicated by the second hand 5. Hereinafter, differences from the second embodiment will be mainly described.

In the fast-forward operation according to this modification, the remaining of the fast-forward rotation operation of the hour hand 3 and the minute hand 4 based on the difference between the hour / minute hand set position data and the hour / minute hand current position data and the set value of the rotation speed of the hour hand 3 and the minute hand 4. A time (second) is calculated, and remaining time data R indicating the remaining time is stored in the RAM 43. When the remaining time is 30 seconds or more (that is, when R ≧ 30), the second hand 5 is fixed at the position of “30 seconds”, and when the remaining time becomes less than 30 seconds (that is, R <30). The second hand 5 is rotated in accordance with the remaining time and moved to the position of “R seconds”. By the rotation operation of the second hand 5, the remaining time of the fast-forward rotation operation of the hour hand 3 and the minute hand 4 is displayed.
Note that the display period of the remaining time by the second hand 5 is not limited to a range of less than 30 seconds and can be arbitrarily set, but is preferably set to a range of less than 1 minute so that the user can easily grasp the remaining time.
In the present modification, the control for indicating the remaining time of the fast-forward rotation operation by the second hand 5 corresponds to the rotation amount information display control.

FIG. 10 is a flowchart showing a control procedure by the CPU 41 of the fast-forward process according to this modification.
This flowchart deletes step S502 from the fast-forward process according to the second embodiment, adds steps S515 to S517 between steps S501 and S503, and steps S506 and S511 to step S518 and step S519, respectively. It has been changed. The other steps are the same as those in the second embodiment, and a description thereof will be omitted.

  When the process of step S501 ends, the CPU 41 calculates the remaining time (R seconds) based on the hour / minute hand set position data, the hour / minute hand current position data, and the setting values of the rotational speeds of the hour hand 3 and the minute hand 4, and the remaining time. Is less than 30 seconds (step S515). If it is determined that the remaining time is less than 30 seconds (“Yes” in step S515), the CPU 41 rotates the second hand 5 at a speed of 32 pps and moves it to the “R second” position (step S516). ). If it is determined that the remaining time is 30 seconds or more (“No” in step S515), the CPU 41 rotates the second hand 5 at a speed of 32 pps and moves it to the “R second” position (step S517). ).

  Further, when the process of step S505 is completed, the CPU 41 executes a remaining time display process for displaying the remaining time of the fast-forward rotation operation of the hour hand 3 and the minute hand 4 by the second hand 5 (step S518). Further, the CPU 41 executes the remaining time display process even when the process of step S510 is completed (step S519).

  FIG. 11 is a flowchart showing a control procedure by the CPU 41 of the remaining time display process.

  When the remaining time display process is started, the CPU 41 substitutes the number obtained by adding 1 to the number of moved steps and stores the number in the RAM 43 (step S701).

  The CPU 41 assigns the value of int ((number of moved steps−number of moved steps) / 32) to the remaining time data R and stores it in the RAM 43 (step S702). Here, “32” is the value of the fast feed rotation speed (pps) of the hour hand 3 and the minute hand 4, and when the fast feed rotation operation is performed at a rotation speed other than 32 pps, the value of the rotation speed is used.

The CPU 41 determines whether or not the remaining time (R seconds) indicated by the remaining time data is less than 30 seconds (step S703). If it is determined that the remaining time is less than 30 seconds (“Yes” in step S703), the CPU 41 rotates the second hand 5 at a speed of 32 pps and moves it to the “R second” position (step S704). ). If the second hand 5 is already in the “R second” position at the start of the process in step S703, the CPU 41 ends the process in step S703 without moving the second hand 5.
If it is determined that the remaining time is 30 seconds or longer (“No” in step S703), the CPU 41 ends the remaining time display process.

  As described above, in the rotation amount information display control, the CPU 41 of the electronic timepiece 1 according to this modification causes the second hand 5 to perform a rotation operation indicating the remaining time of the fast-forward rotation operation of the hour hand 3 and the minute hand 4 (control means). ). Accordingly, the remaining time of the fast feed rotation operation can be notified to the user without affecting the fast feed rotation operation of the hour hand 3 and the minute hand 4.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, in each of the above-described embodiments and modifications, the description has been given using the example in which the hour hand 3 and the minute hand 4 are rotated in conjunction with each other. However, the present invention is applied to an electronic timepiece in which the hour hand 3 and the minute hand 4 are rotated independently. May be applied.

  Further, in the first embodiment, the example in which the preliminary operation is performed in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 has been described, but the fast-forward rotation operation of an arbitrary pointer (rotation display body) provided in the electronic timepiece. In this case, a preliminary operation can be performed with the guideline. For example, the preliminary movement may be performed by the second hand 5 in the fast-forward rotation operation of the second hand 5. Further, in an electronic timepiece provided with function hands other than the hour hand 3, the minute hand 4, and the second hand 5, a preliminary operation may be performed by the function hands in the fast forward rotation operation of the function hands. Further, the preliminary operation may be performed a plurality of times, for example, twice in the fast-forward rotation operation of the hour hand 3 and the minute hand 4. The user can reconfirm the positions of the hour hand 3 and the minute hand 4 at the start of the fast-forwarding operation, and can more reliably assume a waiting time until the end of the fast-forwarding rotation operation, thereby improving user convenience. Further, before performing the preliminary operation in the fast-forward rotation operation of the hour hand 3 and the minute hand 4, for example, the second hand 5 is moved to the position of the minute hand 4 at the start of the fast-forward operation, and the preliminary operation is performed after overlapping the minute hand 4. May be. Also in this case, the user can reconfirm the positions of the hour hand 3 and the minute hand 4 at the time of starting the fast-forwarding operation, can more reliably assume the waiting time until the end of the fast-forwarding rotation operation, and can improve user convenience. .

  In the first embodiment, the preliminary operation related to the fast feed rotation operation of the hour hand 3 and the minute hand 4 has been described using an example in which the hour hand 3 and the minute hand 4 are rotated in the direction opposite to the fast feed rotation operation. Instead of this, an operation of rotating the hour hand 3 and the minute hand 4 in the same direction as the fast-forward rotation operation may be a preliminary operation. In this case, it is preferable that the mode of the rotation operation of the preliminary operation is different from the mode of the fast-forward rotation operation so that the user can distinguish between the preliminary operation and the fast-forward rotation operation. For example, the speed of the preparatory rotation operation can be made different from the speed of the fast-forward rotation operation. Alternatively, the fast-forward rotation operation may be started after a predetermined waiting time has elapsed after the preliminary operation is completed.

  In the first embodiment, the preliminary operation using the hour hand 3 and the minute hand 4 and the operation for gradually decreasing the speed of the fast-forward rotation operation of the hour hand 3 and the minute hand 4 have been described. One of the operations may not be performed, and the information related to the rotation amount in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 may be indicated only by the other operation.

  Further, in the second embodiment and the modified example, the description has been given using the example in which the display relating to the rotation amount in the fast-forward rotation operation of the hour hand 3 and the minute hand 4 is performed by the rotation operation of the second hand 5, respectively. The display related to the rotation amount in the fast-forward rotation operation related to any one of the plurality of hands (rotation display body) may be displayed by the rotation operation of any other hand. For example, when the date indicator 2 is operated to fast-forward and rotate, the second hand 5 displays the ratio of the amount of rotation in the executed rotation operation and the ratio of the remaining amount of rotation in the amount of rotation in the fast-forward rotation operation related to the date indicator 2. Also good. Further, in the electronic timepiece provided with the function hands, display related to the rotation amount in the fast-forward rotation operation of other hands may be performed by the rotation operation of the function hands.

Moreover, you may implement combining the said 1st Embodiment and 2nd Embodiment (or modification). That is, a preliminary operation may be performed in the fast feed rotation operation of the hour hand 3 and the minute hand 4, and a display relating to the rotation amount in the fast feed rotation operation of the hour hand 3 and the minute hand 4 may be performed by the rotation operation of the second hand 5.
