Next, the operation of the prior art will be described with reference to the circuit block diagram of the electronic timepiece shown in FIG. The display means A12 always displays the time using the time display signal S28 output from the time counting means 3. Any one of time display, calendar display, altitude display, inspection display, and memory display is displayed on the display means B13 by the output of the mode signal generating means 5. First, when it is desired to display the time on the display means B13, by selecting the mode switch 4, the mode signal generating means 5 outputs the time calendar mode signal S24, and the in-mode state generating means 6 indicates that the time calendar mode has been selected.

Perform normal time display.

When it is desired to display an altitude display on the display means B13, by selecting the mode switch 4, the mode signal generating means 5 outputs the altitude mode signal S26, and the in-mode state generating means 6 selects the altitude measurement. At the same time, the altitude measurement means 10 and the memory means 19 are enabled. The altitude measuring means 10 receives the function information reference signal S22, performs altitude measurement using the altitude circuit 14, outputs an altitude display signal S31, and displays the altitude on the display means B13. If it is desired to store an altitude value at a certain point during altitude measurement, the in-mode state generating means 6 generates an in-mode state signal S27 and stores it in the memory means 19 by operating the push button B142. When it is desired to display the inspection mode on the display unit B13, the system is reset by pressing the push button A141 and the push button B142 simultaneously for 2 to 2.5 seconds or more, the clock is initialized, and the interrupt switch 143 is turned on. By generating the interrupt signal S38 in the state, the inspection circuit 15 and the memory means 19 are enabled. The mode signal generating means 5 forcibly sets the altitude mode signal S26.
Is output, the altitude measurement means 10 is enabled, and the inspection circuit 15 operates. When the inspection circuit 15 operates, an inspection display signal S37 is output and the display is performed on the display means B13.

In the inspection mode, the inspection circuit 15 operates to start the altitude measurement, and the data is stored in the memory means 19 at a certain interval without operating the push button B142.
Points are memorized. Since the data can be stored in the memory means 19 at regular intervals, the data can be stored in the pressure chamber (a device for changing the atmospheric pressure, which is a device that cannot be accessed because it is sealed) without performing a switch operation.
By changing the pressure in the pressure chamber, it is possible to check the accuracy of the pressure sensor. To return to the normal time display or altitude display from the inspection circuit, push button A14 again.
1. When the push button B142 is simultaneously depressed for 2 to 2.5 seconds or more to reset the system to the initial state, and when the interrupt switch 143 is turned off, the interrupt signal S38 is not generated, and the normal time display state is displayed. You can return to the initial state.

[Problems to be solved by the invention]

However, most of the conventional electronic timepieces cannot be inserted unless a system reset is performed in order to activate a test circuit, and there is a disadvantage that the time set must be set again after the test is completed. Further, a dedicated switch such as the interrupt switch 143 must be provided, and there is a disadvantage that a considerable space is required in a narrow range such as the inside of the timepiece. Even if a system reset is not performed, the test circuit is enabled by a complicated switch operation so that the user does not easily operate the test circuit.

Upon receiving the mode switch signal S23 output from the mode switch 4, the mode signal generating means 5 outputs the time calendar mode signal S24 and selects the time calendar time counting means 7. By keeping the push button A141 pressed for 1 to 1.5 seconds, the state is shifted to the correction state, the year setting of the date / time measuring means 8 is adjusted to the past date before shipment, and the day setting of the day / time measuring means 9 is further set. After the setting, the normal state is returned from the corrected state to the normal state (for example, the setting of the date / time-measuring means 8 is set in January 1998, in accordance with the day of the past that was not set in the date / time-measuring means 8 before shipping). On the first day of the month, it is originally Thursday, so it is set to a day other than Thursday, for example, Wednesday). The date / time information S32 output from the date / time measuring means 8 matches the specific date / time signal S39 output from the specific date / time means 18 and the day information S33 output from the day / time measuring means 9 and the specific day of the week. When the specific day signal S34 output from the means 16 matches, a match signal S35 is output.

When the coincidence signal S35 is output, the power save counter 21 of the power save means 20 is enabled, and the power save counter 21 starts counting. Tell that.

Receives the counter information S43 output from the power saving means 20, adds the counter value, returns the current value to the current time, and outputs a time display signal AS28, a calendar step signal S36, and a calendar display signal S30. By displaying the display means A12 based on the time display signal AS28 and displaying the display means B13 based on the calendar display signal S30, the power save state can be ended.

Next, a third embodiment will be described with reference to a circuit block diagram of the electronic timepiece of FIG. 5 and a top view of FIG. FIG.
The same components as those of the first and second embodiments described with reference to FIG. 4 are denoted by the same reference numerals, and description thereof is omitted.

The present embodiment is a function that allows the user to arbitrarily set the city and the time difference when the user wants to display the city and the time difference other than the pre-registered city and the time difference.
It is intended for watches with the so-called arbitrary city registration function.

Numeral 30 denotes an optional registered city setting means comprising a set city memory 31, a set time difference memory 32, and a temporary save memory 45, which will be described later. Upon receipt, the state is enabled, and city information S54 and time difference information S55 are output. Reference numeral 31 denotes a set city memory for registering a city set by operating the push button B142.
Reference numeral 2 denotes a set time difference memory for registering the time difference set by operating the push button B142, and 45 denotes a stage in which the contents of the set city memory 31 and the set time difference memory 32 are temporarily stored once the arbitrary registration city mode signal is first received. This is a temporary save memory for storing.

Reference numeral 33 designates a predetermined city, which is a specific city means for outputting the specific city signal in S50. Numeral 34 designates a predetermined time difference, and a specific time difference means for outputting the specific time difference signal of S51. 50 is an arbitrary city time difference memory 51 described later,
This is a city time difference storage means in which a pre-registered city and a time difference are stored. The means is enabled by a city time difference selection signal S60, and outputs a city time difference display signal S53. An optional city time difference memory 51 receives and stores the city information S54 and the time difference information S55.

In FIG. 6, reference numeral 40 denotes a city time difference display signal S.
A city display unit that receives 53 and displays the city.
Reference numeral 41 denotes a time difference display unit for receiving the city time difference display signal S53 and displaying the time difference, both of which are displayed in the display means B13.

Next, the operation of the present invention will be described with reference to the circuit block diagram of FIG. 5 and the top view of FIG. In FIG. 5, the specific city means 33 is preset to "YMT", and the specific time difference means 34 is preset to "+25".

In FIG. 6, the city is displayed on the city display section 40.
The time difference display section 41 always displays the time difference.

In the time calendar mode, since the time calendar mode signal S24 is output, any one stored in the city time difference storage means 50 is displayed on the city display 40 and the time difference display 41. Here, if the push button B142 is operated, the city time difference selection signal S60 is output, and the city and the time difference stored in advance in the city time difference storage means 50 are selected in order, and the city time difference display signal S5
3 is displayed on the display means B13. If the city and time difference are already stored in the arbitrary city time difference memory 51,
The push button A142 is operated to be selected after "NYC-5", and a city time difference display signal S53 is output and displayed on the display means B13. FIG. 6 shows a state where “TYO + 9” is selected.

Subsequently, the push button A141 is set to 1-1.
By pressing and holding for 5 seconds, the state is changed to a correction state, and an arbitrary city and an arbitrary time difference are inputted by using setting means (not shown). The input value is displayed on the city display section 40 and the time difference display section 41. When the setting of the time difference with the arbitrary city is completed and the push button A141 is operated, the time is stored in the arbitrary city time difference memory 51 and output to the matching circuit 17.

Next, the case of shifting to the power save mode will be described. The city of the set city memory 31 registered and displayed in the correction state in the arbitrary registration city mode state is adjusted to the city that cannot be normally set, and the set time difference memory 32 is returned to the normal state according to the unusable time difference (for example, Y from Yabadai, where there is no set city
Set to MT and set the time difference to 25 since the time difference can only be 0 to 23 hours). The city information S54 output from the set city memory 31 matches the specific city signal S50 output from the specific city means 33, and the time difference information S55 output from the set time difference memory 32 and the specific time difference output from the specific time difference means 34. When the signals S51 match, a match signal S35
Is output.

When the coincidence signal S35 is output, the power save counter 21 of the power save means 20 is enabled, and the power save counter 21 starts counting and outputs the power save state signal S42 at the same time. The mode generating means 5 which has received the power save state signal S42 outputs the power save state to the in-mode state generating means 6, the time / calendar clocking means 7, the optional registered city setting means 30, and the city time difference storage means 50. .
In response to this output, the time / calendar timer 7 enters the disable state. The output of the time display signal AS28 is stopped by setting the time counting means 3 to the disable state, and the display means A12 stops the hand movement. Similarly, the time difference storage means 50 is in the disable state. Urban time difference storage means 50
Is set to the disable state, so that the city time difference storage signal S5
3 is stopped, and the display means B13 turns off the display.
Accordingly, the hand operation stops and the display turns off, and the state shifts to the power saving state. During this time, the power save counter 21 continues counting at one second intervals until the power save state is released.

To end the power save, the user operates the push button A141 or the push button B142. With this operation, the power saving means 20 cancels the power saving state. When the power save is released, the power save state signal S42 is transmitted to the mode signal generating means 5. Further, it outputs a counter information signal S43.

The mode signal generating means 5 outputs a time calendar mode signal S24 for enabling the time calendar clocking means 7 to enable the time calendar clocking means 7. Optional registration city setting means 30
And an arbitrary registration city mode signal S60 for enabling the city time difference storage means 50.

Time counting means 3 in enabled state
Receives the counter information S43 output from the power saving means 20, adds the counter value, restores the current time, and then outputs the time display signal AS28 and the calendar step signal S36. The hand movement of the display means A12 is restarted based on the signal of the time display signal AS28.

Similarly, the enabled optional registered city setting means 30 sends the information saved in the temporary save memory 45 to the set city memory 31 and the set time difference memory 32, and outputs the city information S54 and the time difference information S55.

Similarly, the enabled arbitrary city time difference memory 50 receives the city information S54 and the time difference information S55, and outputs a city time difference display signal S53. The display means B13 is displayed again based on the signal of the city time difference display signal S53.

The power saving state can be ended by displaying the display means A12 based on the signal of the time display signal AS28 and displaying the display means B13 based on the signal of the city time difference display signal S53.

As is apparent from the above description, according to the present invention, even when it is desired to activate the inspection circuit, the inspection can be performed without performing the system reset, so that it is not necessary to set the time again after the inspection. In addition, it is possible to shift to the inspection or power save state without providing an interrupt switch, and it is possible to secure a space inside the timepiece. In addition, by setting the date before the product was already shipped, and by setting a day that cannot be the original date, the inspection can be operated without the user's notice, or a predetermined circuit including a power saving circuit. It became possible to work.

Further, by setting a nonexistent city and a further impossible time difference, it is possible to operate the inspection without noticing the user or to operate a predetermined circuit including a power saving circuit.

As described above, according to the present invention, the mode of the timepiece is shifted by setting the control means for controlling the additional function to a specific state, so that no special switch is required. Also, it became possible to change the mode of the watch.
