[0009] An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, an electronic timepiece 1 includes a housing 101 that houses an analog display unit 20 and a circuit board (not shown), and two bands 102 attached to the housing 101. The electronic timepiece 1 is a wristwatch worn on a user's wrist by wrapping the band 102 around the wrist. Hereinafter, the direction parallel to the dial of the analog display unit 20 and extending from the center of the dial toward the 3 o'clock direction is defined as the +X direction, the direction parallel to the dial and extending from the center of the dial toward the 12 o'clock direction is defined as the +Y direction, and the normal direction to the dial is defined as the +Z direction. The housing 101 is rectangular with rounded corners when viewed from the +Z direction. A touch operation unit 30 (touch panel) capable of detecting touch operations using an operating tool such as a user's finger is provided on the side of the housing 101 facing the +X direction. As shown in FIG. 2, the touch operation unit 30 has a substantially planar operation surface 30a that extends in the Y direction when viewed from the +X direction. An operation button 41 that can be pressed is provided on the side surface of the housing 101 on the -X direction side. The shape of the housing 101 is not limited to being approximately rectangular. For example, the housing 101 may be approximately circular when viewed from the +Z direction, and the operation surface 30a of the touch operation unit 30 may be curved according to the shape of the housing 101.

[0010] 3, the electronic watch 1 includes a CPU 11 (Central Processing Unit) (control unit, control means), a RAM 12 (Random Access Memory), a storage unit 13, an analog display unit 20, a touch operation unit 30, a button operation unit 40, a timing unit 50, and an alarm unit 60. The various units of the electronic watch 1 are connected via a data transmission path such as a bus.

[0011] The CPU 11 is a processor that controls the operation of the electronic watch 1 by reading and executing the program 131 stored in the storage unit 13 and performing various arithmetic processing. The electronic watch 1 may have multiple processors (e.g., multiple CPUs), and the multiple processes performed by the CPU 11 of this embodiment may be executed by these multiple processors. In this case, the control unit is made up of the multiple processors. In this case, the multiple processors may be involved in a common process, or the multiple processors may independently execute different processes in parallel. The RAM 12 provides working memory space for the CPU 11 and stores temporary data.

[0012] The storage unit 13 is a non-transitory recording medium readable by the CPU 11 as a computer, and stores a program 131 and various data. The storage unit 13 has a non-volatile memory such as a flash memory. The program 131 is stored in the storage unit 13 in the form of a program code readable by the computer. The data stored in the storage unit 13 includes selection operation setting data 132 and movement amount setting data 133 (movement amount setting information), which will be described later.

[0013] The analog display unit 20 has an hour hand 21, a minute hand 22, a second hand 23, and a function hand 24 (multiple hands). Of these, the hour hand 21, minute hand 22, and second hand 23 rotate around a rotation axis located in the center of the dial of the analog display unit 20, as shown in FIG. 1, to display the current hour, minute, and second, respectively. The function hand 24 is a small hand that rotates within a small circular dial (sub-dial) located on the -Y direction side of the center of the dial. The function hand 24 displays, for example, the status of the electronic timepiece 1, such as the operating mode, the day of the week, etc. Hereinafter, when two or more of the hour hand 21, minute hand 22, second hand 23, and function hand 24 are referred to collectively, they will be referred to as "hands 21 to 24."

[0014] The analog display unit 20 further includes gear train mechanisms 241-244, which are multiple gear trains connected to the hour hand 21, minute hand 22, second hand 23, and function hand 24, respectively; stepping motors 251-254 that rotate the gear train mechanisms 241-244, respectively; and a motor drive circuit 26 that drives the stepping motors 251-254. The hour hand 21 rotates by an angle corresponding to one second in response to the stepping movement of the stepping motor 251 transmitted via the gear train mechanism 241. The minute hand 22 rotates by an angle corresponding to one second in response to the stepping movement of the stepping motor 252 transmitted via the gear train mechanism 242. The second hand 23 rotates by an angle corresponding to one second in response to the stepping movement of the stepping motor 253 transmitted via the gear train mechanism 243. The function hand 24 rotates by a predetermined angle in response to the stepping movement of the stepping motor 254 transmitted via the gear train mechanism 244. The rotation angle of the second hand 23 corresponding to one second is 6 degrees, the rotation angle of the minute hand 22 is 1 / 60 of the rotation angle of the second hand 23, and the rotation angle of the hour hand 21 is 1 / 12 of the rotation angle of the minute hand.

[0015] The stepping motors 251-254 are each step-driven based on the voltage waveform of a drive pulse input from the motor drive circuit 26, rotating the hands 21-24 in the forward direction (the direction in which time advances) or the reverse direction (the direction in which time retreats) by the predetermined rotation angle described above. Among these, the stepping motors 251-253 are driven by a drive pulse of 1 pps (pulse per second) while the time is being displayed. The stepping motors 251-254 are also driven by drive pulses of up to several tens to several hundred pps in the forward and reverse directions, allowing the hands 21-24 to rotate rapidly in the forward or reverse direction. The hands 21-24 are connected to separate wheel train mechanisms and stepping motors, and can therefore rotate independently of each other. The motor drive circuit 26 outputs drive voltage pulses with appropriate timing and pulse width to drive the stepping motors 251-254 to perform stepwise movements in response to a control signal input from the CPU 11.

[0016] The hour hand 21 and minute hand 22 may be designed to rotate in unison. That is, the hour hand 21 and minute hand 22 may be connected to a train wheel mechanism for the hour hand 21 and a train wheel mechanism for the minute hand 22, respectively, which transmit the step motion of a common stepping motor. Furthermore, the method of movement of the hands 21 to 24 is not limited to step movement using the stepping motors 251 to 254, but may be sweep movement (continuous movement) using a sweep motor that rotates continuously at a constant speed.

[0017] The touch operation unit 30 detects whether or not a finger F is in contact (touching) with the operation surface 30a and the touch position, and outputs a signal related to the detection result to the CPU 11. The touch operation unit 30 includes a touch sensor 31 and a sensor control unit 32 that performs processing related to the detection of the finger F using the touch sensor 31. As shown in FIG. 4 , the touch sensor 31 is stored inside the housing 101 at a position along the inner wall of the housing 101. The touch operation unit 30 also includes a protective layer 101a that protects the touch sensor 31. The protective layer 101a protects the touch sensor 31, and its surface functions as the operation surface 30a of the touch operation unit 30. The protective layer 101a is made up of a portion of the housing 101 that overlaps with the touch sensor 31 when viewed from the +X direction. The protective layer 101a may be continuous with other portions of the housing 101, or the boundary with other portions of the housing 101 may be visible for the purpose of making the area of ​​the operation surface 30a easier to understand. Alternatively, the touch operation unit 30 including the touch sensor 31 and the protective layer 101a may be prepared as a separate structure from the housing 101, and the touch operation unit 30 may be fitted into an opening provided in the housing 101. In this case, the protective layer 101a functions as part of the housing 101 after being fitted into the opening.

[0018] The touch sensor 31 of this embodiment is a capacitance-type sensor. Specifically, the touch sensor 31 is a self-capacitance type sensor that detects contact of the finger F with the operation surface 30a based on changes in capacitance C generated between the finger F and the touch sensor 31. The touch sensor 31 has multiple electrodes (not shown) arranged in the Y direction. The sensor control unit 32 detects the capacitance C between the multiple electrodes and the finger F, and detects contact of the finger F with the operation surface 30a when the capacitance C generated between any electrode and the finger F increases to or exceeds a predetermined threshold Ct as the finger F approaches. The sensor control unit 32 also identifies the touch position of the finger F based on the position of an electrode among the multiple electrodes where the capacitance C is equal to or greater than the threshold Ct. The sensor control unit 32 transmits a signal related to the detection result of the contact and the touch position to the CPU 11. The touch operation unit 30 configured as described above can detect a tap operation in which the finger F touches the operation surface 30a and then releases the finger F, a long press operation in which the finger F continues to touch the operation surface 30a, and a slide operation in which the touch position is slid across the operation surface 30a. It should be noted that the value of the capacitance C itself does not have to be used to detect contact, and a value corresponding to the capacitance C may be used. In this case, the threshold value Ct may also be converted into a value corresponding to the capacitance C. At least a part of the processing executed by the sensor control unit 32 of the touch sensor 31 may be executed by the CPU 11.

[0019] 5, the magnitude of the capacitance C generated by the approach or contact of the finger F is proportional to the value of S / d. Here, d is the distance between the surface (sensor surface) of the touch sensor 31 and the finger F, and S is the area of ​​the finger F and the portion of the electrode of the touch sensor 31 that functions as a capacitive electrode. Therefore, the capacitance C increases as the finger F approaches the operation surface 30a (as the distance d decreases), and after the finger F comes into contact with the operation surface 30a, the capacitance C increases as the contact area with the operation surface 30a increases by pressing the finger F against the operation surface 30a (as the area S increases).

[0020] The smaller the threshold Ct, the higher the operation detection sensitivity of the touch operation unit 30. The sensor control unit 32 of the touch operation unit 30 in this embodiment can switch the threshold Ct between a first threshold Ct1 and a second threshold Ct2, which is smaller than the first threshold Ct1, under the control of the CPU 11. Hereinafter, the operation detection sensitivity of the touch operation unit 30 when the threshold Ct is set to the first threshold Ct1 will be referred to as the "first sensitivity," and the operation detection sensitivity of the touch operation unit 30 when the threshold Ct is set to the second threshold Ct2 will be referred to as the "second sensitivity." The second sensitivity is higher than the first sensitivity. When the touch operation unit 30 has the first sensitivity, the touch operation unit 30 detects contact of the finger F when the finger F is in contact with the operation surface 30a with a contact area equal to or larger than a certain value. On the other hand, when the touch operation unit 30 has the second sensitivity, the touch operation unit 30 detects contact of the finger F even when the finger F is in slight contact with the operation surface 30a.

[0021] The button operation unit 40 has operation means such as the operation button 41 shown in FIG. 1 and a crown (not shown), and outputs to the CPU 11 an operation signal corresponding to an operation performed on the operation means.

[0022] The timekeeping unit 50 includes an oscillation circuit, a frequency dividing circuit, a timekeeping circuit, etc. The frequency dividing circuit divides the clock signal generated by the oscillation circuit, and the timekeeping circuit counts the divided signal, thereby counting and holding the current date and time.

[0023] The notification unit 60 includes a piezoelectric speaker and outputs a predetermined notification sound at a timing according to a control signal transmitted from the CPU 11. Note that the method of notification by the notification unit 60 is not limited to outputting the notification sound from a piezoelectric speaker. For example, the notification unit 60 may include a light-emitting unit and may be able to notify by emitting light from the light-emitting unit. Furthermore, the notification unit 60 may include a vibration unit and may be able to notify by vibrating the vibration unit.

[0024] Next, the operation of the electronic timepiece 1 will be described. As described above, the hands 21 to 24 of the analog display unit 20 move stepwise under the control of the CPU 11, but the CPU 11 cannot detect the position of each hand 21 to 24. Therefore, if the hands 21 to 24 deviate from their appropriate positions for some reason, the hands 21 to 24 will continue to move with that deviation. For example, if any of the hands 21 to 23 deviates from the current time position, the time measured by the timing unit 50 and the time displayed by the hands 21 to 23 will remain different. Therefore, the CPU 11 of this embodiment can switch the operation mode of the electronic timepiece 1 between a time display mode that displays the current time and a correction mode that corrects the positions of the hands 21 to 24 to appropriate positions. In the correction mode, the positions of the hands 21 to 24 can be corrected by intuitive operation of the touch operation unit 30. The electronic timepiece 1 may also be capable of operating in operation modes other than the time display mode and the correction mode, such as a stopwatch mode or a timer mode.

[0025] 6 and 7, the hand position correction process executed by the CPU 11 to correct the positions of the hands 21 to 24 will be described below. The hand position correction process is initiated when the electronic timepiece 1 is powered on and started up. When the hand position correction process is initiated, the CPU 11 switches the operation mode of the electronic timepiece 1 to time display mode (step S1). Note that if the electronic timepiece 1 is already in time display mode when started up, step S1 is skipped. The CPU 11 sets the operation detection sensitivity of the touch operation unit 30 to a first sensitivity (step S2). Here, the CPU 11 sends a control signal to the sensor control unit 32 of the touch operation unit 30, and sets the threshold Ct used to determine whether or not a finger F is in contact to a first threshold Ct1. Thereafter, the touch operation unit 30 detects contact of the finger F when the capacitance C between the touch sensor 31 and the finger F is equal to or greater than the first threshold Ct1, and outputs a signal related to the detection result, including the detected position of the finger F, to the CPU 11.

[0026] The CPU 11 moves the hands 21 to 23 to display the current time (step S3). Here, the CPU 11 sends a control signal to the motor drive circuit 26 to operate the stepping motors 251 to 253, thereby moving the hands 21 to 23, and causes the hands 21 to 23 to display the hours, minutes, and seconds of the current time being measured by the timekeeping unit 50. The CPU 11 also moves the function hand 24 at necessary times, such as when switching the day of the week indicated by the function hand 24.

[0027] The CPU 11 determines whether a long press operation on the operation surface 30a of the touch operation unit 30 has been detected (step S4). This long press operation is one form of a "second operation" on the touch operation unit 30 and is a predetermined operation for switching the operation mode of the electronic timepiece 1 from the time display mode to the correction mode. Note that the second operation is not limited to a long press operation on the touch operation unit 30 and may be another predetermined operation on the touch operation unit 30, such as a double tap. Furthermore, the switching operation is not limited to the second operation on the touch operation unit 30 and may be an operation of pressing or long pressing one of the operation buttons 41. The CPU 11 determines that a long press operation has been performed when the duration of the state in which the capacitance C between the touch sensor 31 and the finger F is equal to or greater than the first threshold Ct1 exceeds a predetermined reference time. In step S4, the operation detection sensitivity of the touch operation unit 30 is set to the first sensitivity, which is the lower of the two settings. Therefore, contact is not detected unless the finger F is in contact with the operation surface 30a with a contact area equal to or greater than a certain value. This makes it less likely that the electronic timepiece 1 will switch to the correction mode unintentionally. If it determines that a long press operation has not been performed ("NO" in step S4), the CPU 11 returns the process to step S3. If it determines that a long press operation has been performed ("YES" in step S4), the CPU 11 switches the operation mode of the electronic timepiece 1 to the correction mode (step S5), and executes the subsequent steps S6 to S15 related to the correction mode.

[0028] The CPU 11 sets the operation detection sensitivity of the touch operation unit 30 to the second sensitivity (step S6). Here, the CPU 11 sends a control signal to the sensor control unit 32 of the touch operation unit 30 to switch the threshold Ct used to determine whether or not a finger F is in contact with the touch sensor 31 from the first threshold Ct1 to the second threshold Ct2. Thereafter, the touch operation unit 30 detects contact with the finger F when the capacitance C between the touch sensor 31 and the finger F is equal to or greater than the second threshold Ct2, and outputs a signal related to the detection result, including the detected position, to the CPU 11. The CPU 11 determines whether or not an operation on the touch operation unit 30 has been detected (step S7). If the CPU 11 determines that an operation has not been detected ("NO" in step S7), the CPU 11 detects whether a predetermined waiting time has elapsed (whether a timeout has occurred) (step S8). If the CPU 11 determines that the waiting time has elapsed ("YES" in step S8), the CPU 11 returns the process to step S1 and switches the operation mode to the time display mode. If it is determined that the waiting time has not elapsed ("NO" in step S8), the CPU 11 returns the process to step S7.

[0029] If it is determined that an operation on the touch operation unit 30 has been detected ("YES" in step S7), the CPU 11 determines whether the detected operation is a long press operation (step S9). The long press operation here is an operation that is predetermined and stored in the memory unit 13 as a third operation for switching the operation mode of the electronic watch 1 from correction mode to time display mode. The third operation may be an operation different from the second operation. If it is determined that the operation is a long press operation ("YES" in step S9), the CPU 11 returns the process to step S1 and switches the operation mode to time display mode.

[0030] If it is determined that the detected operation is not a long press operation ("NO" in step S9), the CPU 11 determines whether the detected operation is one of a plurality of predetermined selection operations (plural operations) that are different from one another (step S10). Here, the CPU 11 determines whether the detected operation is a selection operation by referring to the selection operation setting data 132 shown in FIG. 8. In the example shown in FIG. 8, the second hand 23 is associated with a single tap as a selection operation, i.e., an operation of touching the operation surface 30a with a finger F and then immediately releasing it. The minute hand 22 is associated with a double tap as a selection operation, i.e., an operation of repeating a single tap twice in succession. The hour hand 21 is associated with a triple tap as a selection operation, i.e., an operation of repeating a single tap three times in succession. The function hand 24 is associated with a multi-touch as a selection operation, i.e., an operation of touching two different positions on the operation surface 30a with a finger F. Note that these are only examples of selection operations, and any other operation may be used. These selection operations are accepted only after switching to the correction mode, and are not accepted in any operation mode other than the correction mode (the time display mode in this embodiment).

[0031] If it is determined that the detected operation is not a selection operation ("NO" in step S10), the CPU 11 quickly moves the hour hand 21, minute hand 22, and second hand 23 around once to notify the user that the operation is invalid (step S11). Note that the movement of the hands that notifies the user of the invalid operation is not limited to this, and may be a movement of all the hands moving back and forth within a certain range. In addition, the notification unit 60 may also issue a predetermined notification. Alternatively, the invalid operation may be notified only by a notification from the notification unit 60, without moving the hands.

[0032] If the CPU 11 determines that the detected operation is any of the selection operations ("YES" in step S10), the CPU 11 identifies the hand associated with the selection operation in the selection operation setting data 132 as the hand to be corrected (step S12). The CPU 11 also moves the hand to be corrected in a predetermined hand movement pattern to notify the user of the hand to be corrected (step S13). For example, as shown in FIG. 9, if a single tap is detected as the selection operation, the CPU 11 identifies the second hand 23 as the hand to be corrected. To notify the user of the hand to be corrected, the CPU 11 moves the second hand 23 back and forth within a certain angular range centered on the current position of the second hand 23. The certain angular range may be, for example, about ±5 graduations (±5 seconds in the display unit of the second hand 23) with the scale 201 representing one second of the second hand 23 (one minute of the minute hand 22) as the unit. The reciprocating period of the second hand 23 may be about one second to several seconds. The reciprocating movement may be repeated a predetermined number of times (for example, three times). Instead of moving the pointer to be corrected back and forth, the pointer may be rotated once.

[0033] The CPU 11 references the movement amount setting data 133 and acquires the setting of the movement amount of the pointer to be corrected (step S14). As shown in FIG. 10, the movement amount setting data 133 stores, for each of the pointers 21 to 24, the operation amount of the first operation on the touch operation unit 30 and the movement amount of the pointer corresponding to the operation amount, in association with each other. In this embodiment, the first operation is a slide operation in which the touch position is slid on the operation surface 30a, and the operation amount is the slide amount of the slide operation. The "operation amount" in the movement amount setting data 133 is expressed as a numerical value when the operation amount when the touch position is slid from one end to the other end in the Y direction of the touch operation unit 30 is set to "10". Furthermore, the "movement amount" in the movement amount setting data 133 is expressed as a value in units of the scale 201. For example, since the "operation amount" for the second hand 23 is set to "1" and the "movement amount" to "4," if the hand to be adjusted is the second hand 23, the second hand 23 is moved by four graduations in response to a slide operation that slides the second hand 23 by 1 / 10 of the length of the operation surface 30a. Similarly, if the hand to be adjusted is the minute hand 22, the minute hand 22 is moved by two graduations in response to a slide operation that slides the second hand 23 by 2 / 10 of the length of the operation surface 30a. Furthermore, if the hand to be adjusted is the hour hand 21, the hour hand 21 is moved by one graduation in response to a slide operation that slides the second hand 23 by 4 / 10 of the length of the operation surface 30a. Furthermore, if the hand to be adjusted is the function hand 24, the function hand 24 is moved by one graduation on the small dial in response to a slide operation that slides the second hand 23 by 6 / 10 of the length of the operation surface 30a. If the detected amount of slide operation is equal to or greater than an integer multiple of the "amount of operation" defined in the movement amount setting data 133, the hands may be moved by an amount of movement obtained by multiplying the "amount of movement" in the movement amount setting data 133 by the integer. Alternatively, an amount of operation of "1" may be set as a reference amount of operation, and the hands may be moved by an amount of movement obtained by multiplying the detected amount of slide operation by the movement amount per reference amount of operation described below for each hand. If an amount of movement of "1" is set as the reference amount of movement, the amount of movement of the second hand 23 per reference amount of operation is "4", the amount of movement of the minute hand 22 per reference amount of operation is "1 (= 2 / 2)", the amount of movement of the hour hand 21 per reference amount of operation is "1 / 4", and the amount of movement of the function hand 24 per reference amount of operation is "1 / 6".Thus, the movement amount per reference operation amount associated with the second hand 23 ("4") is larger than the movement amount per reference operation amount associated with the minute hand 22 ("1"), which in turn is larger than the movement amount per reference operation amount associated with the hour hand 21 ("1 / 4"). Furthermore, the movement amount per reference operation amount associated with the function hand 24 ("1 / 6") is smaller than the movement amount per reference operation amount associated with the hour hand 21. This allows the second hand 23 and minute hand 22, whose positions are often corrected by relatively large amounts of movement, to move significantly with a small amount of operation, while the hour hand 21, whose position is expected to be corrected by a relatively small amount of movement, is prevented from moving too much with a slide operation or a long press operation. It is also possible to register the movement amount per reference operation amount as the "movement amount" in the movement amount setting data 133, and omit the "operation amount."

[0034] Furthermore, CPU 11 determines the direction of movement (correction direction) based on the direction of the slide operation. For example, CPU 11 moves the hands clockwise in response to a slide operation of sliding operation surface 30a in the -Y direction, and moves the hands counterclockwise in response to a slide operation of sliding operation surface 30a in the +Y direction.

[0035] When step S14 ends, the CPU 11 determines whether a slide operation as the first operation has been detected (step S15). If it determines that a slide operation has been detected (step S15: YES), the CPU 11 derives the movement amount of the hand corresponding to the amount of operation of the detected slide operation based on the setting acquired in step S14 (step S16). For example, the CPU 11 derives the movement amount of the hand by multiplying the detected amount of operation by a set value of the movement amount per reference amount of operation. The CPU 11 also sends a control signal to the motor drive circuit 26 to move the hand to be corrected by the derived movement amount (step S17). For example, as shown in FIG. 11, if a slide operation in the −Y direction with an operation amount of “3” is detected, the CPU 11 multiplies the detected operation amount of “3” by the movement amount of the second hand 23 per reference amount of operation of “4” to derive the movement amount of the second hand 23 as “12.” In response to this, the CPU 11 moves the second hand 23 clockwise by 12 graduations as shown in FIG.

[0036] When step S17 is completed, or when it is determined in step S15 that a slide operation has not been detected ("NO" in step S15), the CPU 11 detects whether a long press operation on the touch operation unit 30 has been detected, or whether a predetermined waiting time has elapsed (step S18). When it is determined that a long press operation has not been detected and the waiting time has not elapsed ("NO" in step S18), the CPU 11 returns the process to step S15. Thereafter, every time the CPU 11 detects a slide operation, it executes steps S16 and S17 to move the hand to be corrected and correct its position.

[0037] In step S18, if it is determined that a long press operation has been detected or that the standby time has elapsed ("YES" in step S18), CPU 11 returns the process to step S1 and switches the operation mode to the time display mode. This fixes the corrected position of the hands to be corrected, and thereafter the correct time, etc., reflecting the corrections are displayed by the hands.

[0038] The electronic watch 1 may be operated in an operation mode other than the time display mode, and may also be switched from each of these operation modes to the correction mode in response to a long press operation (second operation) on the touch operation unit 30. In this case, when the electronic watch 1 is operated in an operation mode other than the correction mode, the operation detection sensitivity of the touch operation unit 30 is set to the first sensitivity.

[0039] Furthermore, although a slide operation has been exemplified as the first operation, the present invention is not limited to this. For example, the first operation may be a long press operation in which the operation surface 30a of the touch operation unit 30 is continuously touched. In this case, the operation amount of the first operation is the duration of the long press operation. Furthermore, the "operation amount" in the movement amount setting data 133 may be a value in which a predetermined reference duration (for example, 1 second) is set to "1."

[0040] Next, a modification of the above embodiment will be described. Differences from the above embodiment will be described below. As shown in FIG. 12, the electronic timepiece 1 of this modification has a digital display unit 70 (display unit) instead of the function hand 24. The digital display unit 70 has a dot-matrix or segment liquid crystal panel and a drive circuit that drives the liquid crystal panel under the control of the CPU 11, and displays various information digitally. In this modification, when the CPU 11 determines that any of the selection operations has been performed in step S10 of FIG. 6, it causes the digital display unit 70 to display the hand to be corrected. In FIG. 12, in response to the second hand 23 being selected as the hand to be corrected, the digital display unit 70 displays "Sec" representing the second hand 23.

[0041] As described above, the electronic timepiece 1 according to this embodiment includes a plurality of hands 21-24, a touch operation unit 30 that accepts touch operations, and a CPU 11. When the CPU 11 detects one of a plurality of different selection operations on the touch operation unit 30 that are pre-associated with the plurality of hands 21-24, it identifies the hand among the plurality of hands 21-24 that corresponds to the detected selection operation as the hand to be corrected. This allows the hand to be selected by a simple and intuitive operation on the touch operation unit 30. Therefore, since there is no need to use multiple buttons or a crown, the hand can be selected with a simple operation. This allows the desired hand position to be corrected in a short amount of time.

[0042] Furthermore, after identifying the hand to be corrected, if the CPU 11 detects a slide operation (first operation) on the touch operation unit 30, it corrects the position of the hand to be corrected by moving the hand to be corrected according to the amount of slide operation. This makes it possible to specify the amount of correction to the position of the hand and correct it with a simple and intuitive operation on the touch operation unit 30. Therefore, the desired position of the hand can be corrected in a short time.

[0043] Furthermore, by defining the slide operation as the first operation and the slide amount as the operation amount of the first operation, the amount of movement of the pointer (the amount of correction to the position of the pointer) can be specified in an intuitive manner by adjusting the slide amount of the slide operation.

[0044] The first operation may be a long press operation in which the operation surface of the touch operation unit 30 is continuously touched, and the operation amount of the first operation may be the duration of the long press operation. This makes it possible to specify the movement amount of the needle (the correction amount of the needle position) by an intuitive method of adjusting the duration of the long press operation.

[0045] Furthermore, the CPU 11 derives the amount of movement of the hand to be corrected according to the amount of slide operation detected based on movement amount setting data 133, in which the amount of movement of the hand according to the amount of slide operation is predetermined and associated with each of the multiple hands 21 to 24, and moves the hand to be corrected by the derived amount of movement. This allows the amount of movement of the hand according to the amount of slide operation or long press operation to be different for each hand. Therefore, it is possible to move some hands by a large amount with a small amount of operation, and move other hands by a small amount with a large amount of operation.

[0046] The multiple hands 21 to 24 include an hour hand 21, a minute hand 22, and a second hand 23, and in the movement amount setting data 133, the movement amount per reference operation amount associated with the second hand 23 is larger than the movement amount per reference operation amount associated with the minute hand 22, which is larger than the movement amount per reference operation amount associated with the hour hand 21. This allows the second hand 23 and minute hand 22, whose positions are often corrected by relatively large movement amounts, to move the hands by a large amount with a small amount of operation, and the hour hand 21, whose position is often corrected by a relatively small movement amount, to be prevented from moving too much with a slide operation or a long press operation.

[0047] Furthermore, when the CPU 11 detects a predetermined switching operation by the user, it switches the operation mode of the electronic timepiece 1 to a correction mode for correcting the positions of the multiple hands 21-24, and when the electronic timepiece 1 is operating in an operation mode other than the correction mode, it sets the operation detection sensitivity of the touch operation unit 30 to a first sensitivity, and when the electronic timepiece 1 is operating in the correction mode, it sets the operation detection sensitivity of the touch operation unit 30 to a second sensitivity higher than the first sensitivity. This makes it easier to operate the touch operation unit 30 in the correction mode, which requires operation using the touch operation unit 30. Furthermore, in a mode in which switching from the time display mode to the correction mode is performed by performing a long press operation on the touch operation unit 30, setting the sensitivity to the first sensitivity in the time display mode makes it less likely that the mode will switch to the correction mode unintentionally.

[0048] Furthermore, by treating a long press operation (second operation) on the touch operation unit 30 as a switching operation, switching from the time display mode to the correction mode can also be performed by operating the touch operation unit 30. Therefore, a series of operations from switching the operation mode to correcting the positions of the hands 21 to 24 can be performed using only the touch operation unit 30.

[0049] Furthermore, when a hand to be corrected is identified, the CPU 11 moves the hand to be corrected in a predetermined movement pattern, thereby enabling the user to visually recognize the hand to be corrected in an easily understandable manner.

[0050] Furthermore, the electronic watch 1 according to the modified example includes a digital display unit 70, and when the CPU 11 identifies a hand to be corrected, it causes the digital display unit 70 to display a representation of the hand to be corrected. This also allows the user to visually recognize the hand to be corrected in an easily understandable manner.

[0051] Furthermore, in the control method for the electronic timepiece 1 according to this embodiment, when one of a plurality of different selection operations on the touch operation unit 30 that are pre-associated with the plurality of hands 21 to 24 is detected, the hand corresponding to the detected selection operation is identified as the hand to be corrected from among the plurality of hands 21 to 24. This allows the hand to be selected for correction by a simple and intuitive operation, so that the desired hand position can be corrected in a short time.

[0052] Furthermore, the program 131 according to this embodiment causes the CPU 11 of the electronic timepiece 1 to function as a control means, and when the control means detects one of a plurality of different selection operations on the touch operation unit 30 that are pre-associated with the plurality of hands 21 to 24, the control means identifies the hand among the plurality of hands 21 to 24 that corresponds to the detected selection operation as the hand to be corrected. This allows the hand to be selected by a simple and intuitive operation, making it possible to correct the desired hand position in a short time.

[0053] The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, in the above-described embodiment, the operation detection sensitivity of the touch operation unit 30 is switched between two levels, but it may be switched between three or more levels. That is, the threshold value Ct may be switched between three or more different threshold values ​​Ct. For example, the threshold value Ct and the operation detection sensitivity may be different for each type of hand to be corrected.

[0054] Furthermore, in the above embodiment, a self-capacitance touch sensor 31 has been exemplified, but this is not limiting, and a mutual capacitance touch sensor may also be used. A mutual capacitance touch sensor detects contact or approach of a finger F when the capacitance formed between the transmitting electrode and the receiving electrode becomes smaller than a threshold Ct as the finger F approaches (as capacitance is generated between the finger F). Therefore, in the mutual capacitance method, the operation detection sensitivity of the touch operation unit 30 can be increased by increasing the threshold Ct. Furthermore, a touch sensor using a detection method other than the capacitance method, for example, a resistive film method or an optical method, may also be used.

[0055] Furthermore, in the above embodiment, the case where the positions of the hands 21 to 24 are corrected when there is a discrepancy between the internal time of the electronic timepiece 1 (the time measured by the timing unit 50) and the positions of the hands 21 to 24 is described as an example, but this is not limited thereto. For example, the method of correcting the hand position of the above embodiment may be used to correct the internal time of the electronic timepiece 1. That is, if the internal time of the electronic timepiece 1 differs from the current time and the display by the hands 21 to 24 is inaccurate, the positions of the hands 21 to 24 may be corrected using the method of the above embodiment, and once the corrected positions are confirmed ("YES" in step S18), the internal time of the electronic timepiece 1 may be corrected to the time indicated by the hands 21 to 24. The method of the above embodiment may also be used to correct the displayed time to match the time zone of the current location (time difference correction). In this case, the hour hand 21 may be corrected in one-hour increments.

[0056] Furthermore, in the above embodiment, an electronic timepiece 1 was illustrated as having the hour hand 21, minute hand 22, second hand 23, and function hand 24, but the electronic timepiece 1 only needs to have at least the hour hand 21 and minute hand 22, and the second hand 23 and / or function hand 24 may be omitted. Furthermore, in addition to the hour hand 21 and minute hand 22, the electronic timepiece 1 may also have sub-hour hands and sub-minute hands used to display the local time in cities around the world, alarm time, etc. Furthermore, the positions of these sub-hour hands and sub-minute hands may be adjustable in a correction mode.

[0057] Furthermore, while the above embodiment illustrates an example in which the positions of the actual hands 21-24 (physical hands) are corrected, this is not limiting. The electronic timepiece 1 may also be equipped with a display device such as a liquid crystal display that can display the hands 21-24 and the dial, and instead of the actual hands 21-24, the positions of the hands 21-24 digitally displayed by the display device may be corrected in the same manner as in the above embodiment.

[0058] Alternatively, the selection of the pointer to be corrected may be accepted by touching the touch operation unit 30, and the amount of correction for the position of the selected pointer may be specified by using the operation button 41 or the crown.

[0059] In the above description, an example has been disclosed in which a flash memory in the storage unit 13 is used as a computer-readable medium for the program according to the present invention, but this is not limiting. Other computer-readable media may include information recording media such as a hard disk drive (HDD), a solid state drive (SSD), and a CD-ROM. Furthermore, a carrier wave may also be used as a medium for providing data for the program according to the present invention via a communication line.

[0060] Furthermore, it goes without saying that the detailed configuration and detailed operation of each component of the electronic timepiece 1 in the above embodiment can be modified as appropriate without departing from the spirit of the present invention.

[0061] Although the embodiments of the present invention have been described, the scope of the present invention is not limited to the above-described embodiments, but includes the scope of the invention described in the claims and its equivalents. [Explanation of symbols]
