The oscillating unit in this embodiment includes a 32 kHz crystal resonator, an oscillating circuit, a frequency dividing circuit, and the like (not shown), and generates a pulse signal every second. The oscillation unit calculates the pulse signal generated by the oscillation unit and measures the current time. The time measured is sent to the control unit 22 as the current time.

  When the user operates an operation button provided on the operation unit 14 and the current time measured by the time measuring unit 13 is matched with a time signal based on a standard time reported from a radio or a television, the time measuring unit 13 A time approximate to the standard time can be measured.

  The time display unit 19 displays the time (hour, minute) by digital display using liquid crystal according to the time data sent from the control unit 22.

  The alarm control unit 20 controls the output operation of the alarm output unit 21 that outputs an alarm such as a voice, vibration, or melody by a signal output from the control unit 22.

  The control unit 22 includes a differential time storage unit 15, an offset time calculation unit 16, an alarm time determination unit 17, and an alarm time storage unit 18. In addition, each function part which comprises the control part 22 may implement | achieve each function, when hardware resources which consist of CPU, RAM, etc. which abbreviate | omitted illustration and software cooperate organically.

  In the difference time storage unit 15, a difference time that is a deviation time from the current time intended by the user is stored when the user inputs an operation button provided in the operation unit 14.

  The offset time calculation unit 16 obtains the current time measured by the time measurement unit 13 and the difference time stored in the difference time storage unit 15, and calculates the offset time obtained by adding the difference time to the current time. .

  The time display unit 19 acquires the offset time calculated by the offset time calculation unit 16 and displays it on the display unit of the electronic timepiece 1.

  The alarm time storage unit 18 stores an alarm time intended by the user to output an alarm when the user inputs an operation button provided on the operation unit 14.

  The alarm time determination unit 17 has a current time determination mode that compares the current time acquired from the time measuring unit 13 with the alarm time acquired from the alarm time storage unit 18. In the current time determination mode, when the current time matches the alarm time, a signal instructing the alarm control unit 20 to output an alarm is output.

  Next, processing until the electronic timepiece 1 outputs an alarm will be described.

  In the present embodiment, it is assumed that the difference time, which is a deviation time from the standard time intended by the user, is 5 minutes and is stored in the difference time storage unit 15. When the sign of the difference time is plus, it indicates that the offset time is ahead of the current time, and when the sign of the difference time is minus, it indicates that the offset time is behind the current time. Further, it is assumed that the alarm time at which an alarm intended by the user is output is 12:30 and is stored in the alarm time storage unit 18.

  FIG. 2 is a diagram illustrating processing until the offset time is displayed in the first embodiment. The process flow will be described with reference to the block diagram of FIG. 1 according to the flowchart shown in FIG. The upward arrow in FIG. 2 indicates that it is the same as the time in the previous step.

  In step S32, the offset time calculation unit 16 adds the difference time of 5 minutes acquired from the difference time storage unit 15 to the current time of 12:00 acquired from the time measurement unit 13, thereby obtaining the offset time of 12:05. calculate.

  FIG. 3 shows a flowchart processed by the alarm time determination unit 17. In step S40, it is determined whether or not the current time matches the alarm time at which an alarm is to be output. If they match (Yes), the detection signal A is output to the alarm control unit 20 (step S41). If they do not match (No), the process ends.

The difference time stored in the difference time storage unit 15 is 5 minutes, and the alarm time stored in the alarm time storage unit 18 is 12:30.

  In case 1, since the current time is 12:00, the offset time calculation unit 16 calculates the offset time of 12:05, and the time display unit 19 displays the time of 12:05. Similarly, in case 2, since the current time is 12:25, the off-offset time is calculated as 12:30, and the displayed time is 12:30. In case 3, since the current time is 12:30, the off-offset time is calculated as 12:35, and the displayed time is 12:35.

  In Case 1 and Case 2, the current time does not match the alarm time, so the alarm time determination unit 17 does not output a detection signal. In case 3, the current time coincides with the alarm time, so the alarm time determination unit 17 outputs the detection signal A to the alarm control unit 20.

  As described above, the electronic timepiece 1 of the present embodiment includes the timekeeping unit 13 that measures the current time, the operation unit 14 for the user to input, and the difference that stores the difference time input from the operation unit 14.

  According to this configuration, the time obtained by adding the difference time input from the operation unit to the current time is displayed as an offset time, so that the time deviated from the current time by the difference time intended by the user can be obtained. Can be displayed. Further, it is determined whether or not the current time coincides with the alarm time. If the current time coincides, the alarm control unit is instructed to output the alarm so that the current time becomes the time when the alarm should be output. Can output an alarm.

(Second embodiment)
In the second embodiment, a case where an offset time determination mode for determining whether or not the offset time matches the alarm time will be described.

  FIG. 5 is a block diagram showing a functional configuration of the electronic timepiece 1a in the second embodiment. The block diagram of FIG. 5 is obtained by adding an arrow indicating that the offset time calculation unit 16 outputs to the alarm time determination unit 17 to the block diagram of FIG.

  FIG. 6 is a flowchart of processing performed by the alarm time determination unit 17 in the second embodiment. In step S <b> 45, the offset time calculation unit 16 outputs the calculated offset time to the alarm time determination unit 17. The alarm time determination unit 17 has an offset time determination mode for determining whether or not the acquired offset time matches the alarm time. In the offset time determination mode, the alarm time determination unit 17 outputs the detection signal B to the alarm control unit 20 when they match (Yes) (step S46). If they do not match (No), the process ends.

  FIG. 7 illustrates a current time determination mode in which the alarm time determination unit 17 determines whether or not the current time matches the alarm time, and an offset time determination mode that determines whether or not the offset time matches the alarm time. It is a figure which shows the circuit provided with the switch which switches.

  The user can select at least one of the current time determination mode and the offset time determination mode from the operation unit 14. A mode switching signal input from the operation unit 14 by the user is input to at least one of the mode switching switch A50a and the mode switching switch B50b. When a mode switching signal is input to the mode switch A50a, the current time determination mode is selected, and when a mode switching signal is input to the mode switch B50b, the offset time determination mode is selected.

  The comparator 51 performs processing based on whether the current time described with reference to the flowchart of FIG. 3 and the alarm time match, and whether the offset time described with reference to the flowchart of FIG. 6 matches the alarm time. And a process including

  When the current time determination mode is selected, the comparator 51 determines whether or not the alarm time at which the alarm stored in the alarm time storage unit 18 is to be output matches the current time measured by the time measuring unit 13. Determine. When the offset time determination mode is selected, the comparator 51 determines whether the alarm time to be output of the alarm stored in the alarm time storage unit 18 matches the offset time calculated by the offset time calculation unit 16. Determine whether or not.

  The comparator 51 outputs the detection signal A to the alarm control unit 20 when the alarm time matches the current time when the current time determination mode is selected, and when the offset time determination mode is selected. When the alarm time coincides with the offset time, the detection signal B is output to the alarm control unit 20.

  As described above, the alarm time determination unit 17 of the electronic timepiece 1a in the second embodiment has the current time determination mode described in the first embodiment, and further determines whether or not the offset time matches the alarm time. An offset time determination mode. In the offset time determination mode, when the offset time matches the alarm time, the alarm time determination unit 17 instructs the alarm control unit 20 to output an alarm by outputting the detection signal B.

  According to this configuration, the alarm time determination unit 17 determines whether or not the offset time matches the alarm time. If the offset time matches, the user is instructed to output an alarm to the alarm control unit 20. Therefore, a deviation time from the current time intended is secured, and an alarm can be output at the offset time intended by the user.

  The alarm time determination unit 17 has a current time determination mode for determining whether or not the current time matches the alarm time, and an offset time determination mode for determining whether or not the offset time matches the alarm time. The alarm time determination unit 17 selects at least one of the current time determination mode and the offset time determination mode based on the information input from the operation unit 14.

  According to this configuration, an alarm can be output at at least one of the time when the current time becomes the alarm time or the time when the offset time becomes the alarm time.

  FIG. 8A shows a pulse signal that the alarm control unit 20 outputs to the alarm output unit 21 as the detection signal A when the alarm time determination unit 17 determines that the current time matches the alarm time. FIG. 8B shows a pulse signal that the alarm control unit 20 outputs to the alarm output unit 21 as the detection signal B when the alarm time determination unit 17 determines that the offset time and the alarm time match.

  When the pulse signal is ON, an alarm is output, and when it is OFF, the alarm output is stopped. The ON time Ta shown in the figure is shorter than the ON time Tb.

  The pulse signal shown in FIG. 8A is output while repeating a pulse of ON time Ta at regular intervals. The pulse signal shown in FIG. 8B is output while repeating a pulse that is a combination of a pulse having an ON time Ta and a pulse having an ON time Tb at regular intervals. Further, the OFF time Tc shown in FIG. 8A is different from the OFF time Td shown in FIG. 8B.

  Thus, the alarm output mode in the current time determination mode is different from the alarm output mode in the offset time determination mode.

  According to this configuration, the user can distinguish and recognize whether the current time is the time when the alarm time is reached or the offset time is the time when the alarm time is reached.

  In the present embodiment, it has been described that the pulse signal output from the alarm output unit 21 is distinguished by the ON time or OFF time. However, the time when the alarm time is reached is the current time or the offset time. The method for distinguishing between them includes the difference in the melody output from the alarm output unit 21, the difference in the frequency when the mobile communication terminal such as a watch or a mobile phone is vibrated, the message displayed on the display unit, and the message as voice. The method by the difference etc. may be used.

(Third embodiment)
In the third embodiment, a case will be described in which the standard time is received from the outside and the current time measured by the time measuring unit is corrected.

  FIG. 9 is a block diagram showing a functional configuration of the radio timepiece 1b in the third embodiment. This radio timepiece 1b is provided with an antenna 10, a CDMA receiving unit 11 as a receiving unit, and a current time correcting unit 12 in addition to the functional configuration of the electronic timepiece 1 described in the first embodiment.

  The CDMA receiving unit 11 includes time information indicating a standard time synchronized with the Universal Coordinated Time (UTC), is CDMA (Code Division Multiple Access) -modulated for mobile communication, and is transmitted from a base station. A radio wave is received by the antenna 10 in response to an instruction from the control unit 22, time data is extracted from the received radio wave, and is output to the current time correction unit 12. In the present embodiment, the CDMA receiving unit 11 converts a received radio wave high-frequency signal into a baseband signal, AD-converts it into a digital signal, and converts two digital signals (I signal, The sync channel signal including the time data is acquired by demodulating the sync channel signal with respect to the Q signal and decoding the demodulated sync channel signal. Since the data of the sync channel signal has a predetermined data length and the time information is stored in a predetermined area, the time data can be easily extracted by tracing from the head of the data.

  The current time correction unit 12 acquires time data as the standard time from the CDMA reception unit 11, receives an instruction from the control unit 22, and the acquired standard time matches the current time measured by the time measuring unit 13. As described above, the current time measured by the time measuring unit 13 is corrected.

  Next, a process until the radio timepiece 1b corrects the current time based on the standard time received from the outside and outputs an alarm will be described.

  In the present embodiment, it is assumed that the difference time, which is a deviation time from the standard time intended by the user, is 5 minutes and is stored in the difference time storage unit 15. Further, it is assumed that the alarm time at which an alarm intended by the user is output is 12:30 and is stored in the alarm time storage unit 18.

  As described in the first embodiment, when the sign of the difference time is plus, it indicates that the offset time is ahead of the standard time, and when the sign of the difference time is minus, the offset time is Indicates that it is later than the standard time.

  FIG. 10 is a diagram for explaining processing from the correction of the current time based on the standard time in the third embodiment to the display of the offset time. FIG. 10 is obtained by adding step S30 and step S31 to the flowchart of FIG. 2 referred to in the first embodiment.

  The processing flow will be described with reference to the block diagram of FIG. 9 according to the flowchart shown in FIG. An upward arrow in FIG. 10 indicates that the time is the same as the time in the previous step. Before starting the process, the current time measured by the time measuring unit 13 is 12:00. The offset time calculated by the offset time calculation unit 16 is 12:05 because the difference time is 5 minutes. The display time displayed on the time display unit 19 is 12:05 because the offset time is displayed.

  In step S <b> 30, the CDMA receiver 11 acquires 12:13, which is the standard time, through the antenna 10. At this time, since there is an accuracy error when the time measuring unit 13 measures time, the current time measured by the time measuring unit 13 is assumed to be 12:10. It should be noted that the time counting unit 13 includes a highly accurate oscillation unit, and minimizing the accuracy error when measuring time can minimize the time difference between the standard time and the current time. It is assumed that the time difference between the standard time and the current time is 3 minutes. Further, the offset time and the display time at this point are 12:15 because the difference time is 5 minutes.

  In step S31, the current time measured by the timer unit 13 is corrected. Since the standard time is 12:13, the current time correction unit 12 corrects the current time to 12:13, which matches the standard time.

  In step S32, the offset time calculation unit 16 calculates an offset time. The offset time of 12:18 is obtained by adding the difference time of 5 minutes to the current time of 12:13.

  In step S33, the time display unit 19 displays the offset time 12:18 calculated by the offset time calculation unit 16.

  As described with reference to FIGS. 3 and 4 in the first embodiment, in the third embodiment as well, it is determined whether or not the current time matches the alarm time at which an alarm is to be output. Outputs the detection signal A to the alarm control unit 20.

  As described above in the third embodiment, the radio timepiece 1b includes time information indicating standard time, and acquires time information by receiving and restoring a signal encoded by a CDMA communication method. A CDMA receiving unit 11 and a current time correction unit 12 that corrects the current time to match the standard time based on the time information are provided.

  According to this configuration, the time information indicating the standard time information can be received from the radio wave transmitted from the base station transmitted by the CDMA system, so that the current time with high accuracy with the standard time can be measured. As a result, in the current time determination mode, the time at which the alarm is output has a high matching accuracy with the standard time. In addition, since many base stations are installed in a wide range and the opportunity for reception increases, the opportunity to correct the current time also increases, and even if the movement range of the radio clock or mobile communication terminal becomes wide, it matches the standard time It is possible to measure the current time with high accuracy.

(Fourth embodiment)
In the fourth embodiment, the radio timepiece 1b described in the third embodiment further includes a current time determination mode for determining whether or not the current time matches the alarm time, and whether or not the offset time matches the alarm time. A case where an offset time determination mode for determining whether or not is provided will be described.

  FIG. 11 is a block diagram showing a functional configuration of the radio timepiece 1c according to the fourth embodiment. The block diagram of FIG. 11 is obtained by adding an arrow indicating that it is output from the offset time calculation unit 16 to the alarm time determination unit 17 to the block diagram showing the functional configuration of FIG.

  As described with reference to FIGS. 6 and 7 in the second embodiment, also in the fourth embodiment, the alarm time determination unit 17 determines whether or not the current time matches the alarm time. Mode and an offset time determination mode for determining whether or not the offset time matches the alarm time. Based on information input from the operation unit 14, the alarm time determination unit 17 determines whether the current time determination mode and the offset time determination At least one mode can be selected from the modes.

  According to this configuration, the current time correction unit 12 matches the current time measured by the time measuring unit 13 with the standard time based on the time information indicating the standard time acquired by the CDMA reception unit 11, thereby obtaining the standard time. It is possible to measure the current time with high coincidence accuracy. As a result, in the current time determination mode, the time at which the alarm is output becomes highly accurate with the standard time.

  Furthermore, in the offset time determination mode, the alarm time determination unit 17 determines whether or not the offset time matches the alarm time, and if they match, by instructing the alarm control unit 20 to output an alarm, A difference time, which is a deviation time from the standard time intended by the user, is ensured, and an alarm can be output at a deviation time intended by the user.

  The embodiments described in the first and second embodiments can also be applied to mobile communication terminals such as mobile phones and information processing terminals incorporating a clock function.

  The embodiments described in the third and fourth embodiments can also be applied to mobile communication terminals such as mobile phones and information processing terminals that incorporate a clock function for correcting time by radio waves.

  The embodiment described above can output an alarm at each standard time in two countries having a time difference. For example, the time difference is stored as a difference time in the difference time storage unit, the standard time of one country is timed by the time measuring unit as the current time, and the offset time obtained by adding the difference time is displayed as the standard time of the other country Like that.

  In this way, an alarm can be output when the current time, that is, the standard time of one country becomes the alarm time. Alternatively, the alarm can be output when the offset time, that is, the standard time of the other country becomes the alarm time. Such usage can also be applied to cases where there is a time difference depending on the region in one country because the country is large.

  It can also be applied to daylight saving time systems implemented in Western countries. For example, the time difference between the standard time and the daylight saving time is stored as a difference time in the difference time storage unit, the standard time is counted as the current time by the time counting unit, and the offset time obtained by adding the difference time is displayed as the daylight saving time. To.

  In this way, an alarm can be output when the standard time becomes the alarm time. Alternatively, an alarm can be output when the offset time, that is, daylight saving time, becomes the alarm time.
