[0030]
(2) Operation of the embodiment
First, when the user turns on the portable information terminal 100 and brings it close to the external device 200 (see FIG. 3A), the synchronization is established between the external device 200 (master) and the portable information terminal 100 (slave). Establishment processing, connection authentication processing, and the like are performed (see FIG. 3B).
After the above process is completed and communication is started between the external device 200 and the portable information terminal 100, when the wireless communication unit 110 of the portable information terminal 100 receives data including the reference time Ts from the external device 200, The wireless communication unit 110 issues a command to the CPU 121 that the internal time Tc of the portable information terminal 100 should be corrected, alarm notification, etc. should be performed using the reference time Ts.
[0031]
When the CPU 121 receives the command and the reference time Ts from the wireless communication unit 110, the CPU 121 reads and executes the time correction / alarm notification program stored in the ROM 122.
FIG. 4 is a flowchart showing the flow of the internal time correction / alarm notification process executed by the CPU 121, and FIGS. 5 and 6 are schematic diagrams for explaining the internal time correction / alarm notification process. Note that C1 to C10 and S1 to S10 illustrated in FIGS. 5 and 6 indicate ranges in which the internal time Tc and the reference time Ts can exist, respectively. In the following description, it is assumed that the alarm time Ta is set to 12:00 (alarm flag; “1”).
[0032]
a) When the internal time Tc has not passed the alarm time Ta (Tc <Ta)
When the CPU 121 receives the reference time Ts from the wireless communication unit 110, the CPU 121 reads the internal time Tc set in the counter circuit 32c and also reads the alarm time Ta stored in the alarm time storage area 123a. The alarm time Ta is compared (step S1 → step S2).
[0033]
Here, for example, as shown in FIG. 5A, the internal time Tc has not passed the alarm time Ta (= 12: 00), and the time difference between the alarm time Ta and the internal time Tc is the first value. If it is smaller than the threshold value T1 (= 5 minutes) (step S2; YES), the CPU 121 proceeds to step S3.
The CPU 121 compares the reference time Ts with the alarm time Ta, and as indicated by S1 in FIG. 5A, the reference time Ts is the same as or exceeds the alarm time Ta, and the reference time Ts. If the time difference between the alarm time Ta and the alarm time Ta is determined to be equal to or smaller than the second threshold value T2 (= 5 minutes) (step S3; YES), the alarm flag storage area 123b is referred to. Since the alarm flag is set to “1”, the CPU 121 generates a drive signal to notify the user of the arrival of the alarm time, and transmits it to the notification unit 125 (step S4). The CPU 121 sets the difference Δt between the reference time Ts and the internal time Tc in the counter circuit 32c to correct the internal time Tc (= Ts) (step S5), while the notification unit 125 sounds an alarm sound for a predetermined time. The alarm flag is set to “0” and the process is terminated.
[0034]
On the other hand, as shown in FIG. 5B, the CPU 121 has the same reference time Ts as the alarm time Ta or has passed the alarm time Ta, and the time difference between the reference time Ts and the alarm time Ta is second. When it is larger than the threshold value T2 (step S3 → step S7), the process proceeds to step S8, the alarm flag is set to “0” without notifying the user of the arrival of the alarm time, and the reference time Ts The difference Δt from the time Tc is set to correct the internal time Tc (= Ts) (step S5), and the process is terminated.
[0035]
Further, as shown in FIG. 5C, the CPU 121 determines that the time difference between the alarm time Ta and the internal time Tc is the first threshold value T1 even when the internal time Tc has not passed the alarm time Ta. If it is determined that the above is true (step S2; NO), the process proceeds to step S6.
If the CPU 121 determines in step 6 that the internal time Tc is smaller than the alarm time Ta (step S6; YES), the CPU 121 proceeds to step S7 and compares the reference time Ts with the alarm time Ta. When the CPU 121 determines that the reference time Ts matches the alarm time Ta or has passed the alarm time Ta as shown in FIG. 5C (step S7; YES), the CPU 121 proceeds to step S8 and informs the user of the alarm time. Without notifying the arrival, the alarm flag is set to “0”, the difference Δt between the reference time Ts and the internal time Tc is set in the counter circuit 32c, and the internal time Tc (= Ts) is corrected (step S5). The process ends.
[0036]
Further, as shown in FIG. 5D, the CPU 121 determines that the time difference between the alarm time Ta and the reference time Ts is the same even when the reference time Ts is the same as the alarm time Ta or the alarm time Ta has not elapsed. 2 (step S3 → step S7), the alarm flag is not inverted (alarm flag; “1”), and the process proceeds to step S5, where the counter circuit 32c receives the reference time Ts and the internal time. The difference Δt from the time Tc is set to correct the internal time Tc (= Ts), and the process ends.
[0037]
Further, as shown in FIG. 5E, the CPU 121 determines that the time difference between the internal time Tc and the alarm time Ta is equal to or greater than the first threshold value T1, and the reference time Ts has not passed the alarm time Ta. (Step S2 → step S6 → step S7), the alarm flag is not inverted (alarm flag; “1”), and the process proceeds to step S5, where the counter circuit 32c is set to the difference Δt between the reference time Ts and the internal time Tc. Is set to correct the internal time Tc (= Ts), and the process ends.
[0038]
b) When the internal time Tc has passed the alarm time Ta (Tc ≧ Ta)
When the CPU 121 receives the reference time Ts from the wireless communication unit 110, the CPU 121 reads the internal time Tc set in the counter circuit 32c and also reads the alarm time Ta stored in the alarm time storage area 123a. The alarm time Ta is compared (step S1 → step S2).
[0039]
Here, for example, as shown in FIG. 6A, when the internal time Tc is the same as the alarm time Ta or the alarm time Ta has passed (step S2 → step S6), the CPU 121 proceeds to step S9.
In the CPU 121, the internal time Tc matches the alarm time Ta or the alarm time Ta has elapsed, and the time difference between the reference time Ts and the alarm time Ta is smaller than the third threshold value T3 (= 5 minutes). (Step S9; YES), the process proceeds to step S10.
[0040]
As shown in FIG. 6A, the CPU 121 determines that the reference time Ts is the same as the alarm time Ta or the alarm time has not elapsed, and the time difference between the reference time Ts and the alarm time Ta is the fourth threshold value. If it is determined that the time is equal to or less than T4 (= 5 minutes) (step S10; YES), the process proceeds to step S11, and the alarm flag is set to “0” in order to prevent the alarm sound from sounding twice. Then, the CPU 121 sets the difference Δt between the reference time Ts and the internal time Tc in the counter circuit 32c, corrects the internal time Tc (= Ts) (step S5), and ends the process. As a result, even if the corrected internal time Tc reaches the alarm time Ta again, no alarm sound is generated from the notification unit 125.
[0041]
On the other hand, as shown in FIG. 6B, the CPU 121 determines that the reference time Ts is the same as the alarm time Ta or the alarm time even when the internal time Tc is the same as the alarm time Ta or the alarm time Ta has elapsed. If it is determined that Ta has not elapsed and the time difference between the reference time Ts and the alarm time Ta is equal to or greater than the fourth threshold value T4 (step S10 → step S12), an alarm is issued to sound the alarm sound again. Set the flag to “1”. Then, the CPU 121 sets the difference Δt between the reference time Ts and the internal time Tc in the counter circuit 32c, corrects the internal time Tc (= Ts) (step S5), and ends the process. As a result, when the corrected internal time Tc reaches the alarm time Ta again, an alarm sound is generated from the notification unit 125.
[0042]
If the CPU 121 determines that the time difference between the internal time Tc and the alarm time Ta is greater than or equal to the third threshold T3 (step S9; NO), the process proceeds to step S12 as shown in FIG. 6C.
If the CPU 121 determines in step 12 that the reference time Ts is the same as the alarm time Ta or the alarm time Ta has not elapsed (step S12; YES), as shown in FIG. Set the alarm flag to "1" to play the sound again. Then, the CPU 121 sets the difference Δt between the reference time Ts and the internal time Tc in the counter circuit 32c, corrects the internal time Tc (= Ts) (step S5), and ends the process. As a result, when the corrected internal time Tc reaches the alarm time Ta again, an alarm sound is generated from the notification unit 125.
[0043]
Further, as shown in FIG. 6D, the CPU 121 determines that the time difference between the reference time Ts and the alarm time Ta is the same even when the reference time Ts is the same as the alarm time Ta or the alarm time Ta has elapsed. 4 is greater than the threshold value T4 (step S10 → step S12), the process proceeds to step S5 without changing the alarm flag, and the difference Δt between the reference time Ts and the internal time Tc is set in the counter circuit 32c. Then, the internal time Tc (= Ts) is corrected, and the process ends.
[0044]
Further, as shown in FIG. 6E, the CPU 121 has a time difference between the internal time Tc and the alarm time Ta that is equal to or greater than a third threshold value T3, and the reference time Ts has passed the alarm time Ta. (Step S9 → Step S12), the process proceeds to Step S5 without changing the alarm flag, sets the difference Δt between the reference time Ts and the internal time Tc in the counter circuit 32c, and sets the internal time Tc (= Ts). Correct and finish the process.
[0045]
As described above, according to the portable information terminal 100 according to the present embodiment, when the reference time Ts is received from the external device 200 when the internal time Tc has not passed the alarm time Ta, the internal time Tc and the alarm Only when the time Ta, the reference time Ts, and the alarm time Ta satisfy the predetermined conditions (see FIG. 5A), an alarm sound for notifying the arrival of the alarm time sounds. Therefore, when the condition is not satisfied, for example, when the internal time Tc and the alarm time Ta are set to 10:00 and 12:00, respectively, the user who owns the portable information terminal 100 exceeds the time zone (for example, When the reference time Ts (= 15: 00) is received in a foreign country having a time difference of 5 hours, the internal time Tc is corrected to 15:00 based on the reference time Ts, but no alarm sound is generated. . That is, even when the internal time Tc reaches the alarm time Ta, if it is meaningless to sound the alarm sound, the alarm sound is not sounded. For this reason, it becomes possible to reduce mental pains such as annoying thoughts by the alarm sound.
[0046]
Further, according to the portable information terminal 100, when the internal time Tc is the same as the alarm time Ta or the reference time Ts is received from the external device 200 in a state where the alarm time Ta has elapsed, the internal time Tc, the alarm time Ta, and the reference Only when the time Ts and the alarm time Ta satisfy the predetermined conditions (see FIG. 6A), the alarm sound is prevented from ringing twice. For example, when the reference time Ts (= 11: 58) is received in a state where the internal time Tc and the alarm time Ta are set to 12:03 and 12:00, respectively, the internal time Tc is 11 based on the reference time Ts. However, even if the corrected internal time Tc reaches the alarm time Ta again, the alarm sound does not sound because the alarm sound is sounded once at a close time. For this reason, it becomes possible to reduce mental pains such as annoying thoughts by the alarm sound. In the present embodiment, the case where the portable information terminal 100 receives the reference time Ts from the external device 200 has been described as an example, but the case where the external device 200 receives the reference time Ts from the portable information terminal 100 is also described. Applicable.
[0047]
(3) Modification
Although one embodiment of the present invention has been described above, the above embodiment is merely an example, and various modifications can be made to the above embodiment without departing from the spirit of the present invention. As modifications, for example, the following can be considered.
<Modification 1>
In the above-described embodiment, the case where the first to fourth threshold values T1, T2, T3, and T4 are all set to 5 minutes has been described as an example. It can be appropriately changed according to the design and the like. For example, the first to fourth threshold values T1, T2, T3, T4 are set to 10 minutes, 1 hour, 15 minutes 45 seconds, 1 hour 10 minutes 30 seconds, etc., depending on the hour, minute, second, etc. It is also possible to set the configured time as each threshold value.
Further, when the reference time Ts is received in a state where the internal time Tc has not passed the alarm time Ta, for example, the time difference between the internal time Tc and the alarm time Ta is smaller than the first threshold value described above, and An alarm sound may be sounded when the received reference time Ts has passed the alarm time Ta. Similarly, when the reference time Ts is received when the internal time Tc has passed the alarm time Ta, for example, the time difference between the internal time Tc and the alarm time Ta is smaller than the above-described third threshold value. In addition, when the received reference time Ts has not passed the alarm time Ta, the alarm sound may be prevented from sounding twice.
[0048]
<Modification 2>

In such a configuration, the user selects an alarm mode by operating an operation button or the like in advance. When the CPU 121 receives the reference time Ts from the external device 200 via the wireless communication unit 110, the CPU 121 confirms information related to the set alarm mode stored in the RAM 123 or the like. Here, when the first alarm mode is selected, the flow shown in FIG. 4 is executed. On the other hand, when the second alarm mode is selected, it is confirmed whether the internal time Tc has passed the alarm time Ta and whether the reference time Ts has passed the alarm time Ta.

<Modification 4>
FIG. 7 is a block diagram illustrating a configuration of the portable information terminal 100 according to the fourth modification. 7 other than the RAM 123 is the same as that shown in FIG.
The world time storage area 123c is a storage area for storing a time difference Tj between a current time (hereinafter referred to as world time) Tw and an internal time Tc in various cities (for example, New York, London, etc.) in the world. The world time storage area 123c stores a time difference table TT in which each city name described above is associated with the time difference Tj.

[0051]
When the user who owns the portable information terminal 100 performs an input operation to display the world time, a command to display the world time is sent from the input unit 140 to the CPU 121. When the command is received, the CPU 121 acquires the internal time Tc from the time measuring circuit 32, and acquires the city name and the time difference Tj corresponding to the command from the time difference table TT. The CPU 121 supplies the display unit 130 with the world time Tw obtained by adding the internal time Tc and the time difference Tj and the city name corresponding to the world time Tw, whereby the world time Tw and the corresponding city name are obtained.

Or less (step Sa1 → step Sa2). When the CPU 121 determines that the time difference is smaller than the threshold value T5 (step Sa2; YES), in order to correct the world time Tw obtained as described above, the reference time Ts and the internal time Tc are added to the world time Tw. The world time Tw (= Tw + Δt) is corrected by adding the difference Δt (step Sa3). Similarly, the difference Δt between the reference time Ts and the internal time Tc is set in the counter circuit 32c to set the internal time Tc (= Ts). ) Is corrected (step Sa4), and the process is terminated.
[0054]
On the other hand, when the CPU 121 determines that the time difference between the internal time Tc and the reference time Ts is equal to or greater than a preset threshold value T5 (step Sa2; NO), the CPU 121 skips step Sa3 and proceeds to step Sa4. The difference Δt between the reference time Ts and the internal time Tc is set in the counter circuit 32c to correct the internal time Tc (= Ts), and the process is terminated.
