An example of the present invention will be described below with reference to the drawings.

 FIG. 1 is a block diagram showing the structure of the timepiece device.

Reference numeral 3 denotes a known clock circuit, and the time by the clock circuit 3 is displayed on a display 5 via a display switching device 4. The display 5 is also provided with various displays of the other circuit 6 of the device main body to which the timepiece device is mounted. The display switching device 4 is configured to switch the display of the clock circuit 3 and the display of the other circuit 6 according to a command from the control device 1.

An operation command from the operation device 2 is input to the control device 1, and various controls are performed according to the command. The operation device 2 is provided with a clock key 20. When the clock key 20 is operated, the control device 1 controls the display switching device 4 to display the time information from the clock circuit 3 on the display 5. It is configured as follows.

The control device 1 is also provided with a clock adjustment mode by software. In this mode, the control device 1 controls the clock circuit 3 so as to adjust the time, minute, second, etc. in a predetermined time unit. It is configured. In the clock adjustment mode, a unit for increasing or decreasing the time unit to be adjusted in one direction is provided.

In the method of the present invention, the operation for adjusting the clock can be performed only by a single operating means.

That is, first, the clock key 20 is set for a predetermined time (2 in this embodiment).
When pressed for more than a second), the control device 1 activates the clock adjustment mode. The time unit to be adjusted at this time is a predetermined unit among hours, minutes, and seconds. In this embodiment, a case where only the hour and minute are adjusted will be described. The case where the minute is adjusted first will be described.

In the clock adjustment mode, the control device 1 causes the display 5 to display the current time and blink the display in units of time to be adjusted. Then, by operating the clock key 20 in this adjustment mode, the minute is increased or decreased and changed in one direction. The operation of the clock key 20 may be a continuous operation of continuously pressing or an operation of intermittent pressing.

If the clock key 20 is not operated for a predetermined time (5 seconds in this embodiment), the control device 1 operates the clock circuit 3 to change the time unit to be adjusted from minutes to hours. At this time, the display on the display 5 is also made to blink the hour display. In this mode, the time is similarly increased or decreased by operating the clock key 20 to change the time in one direction. In this mode, the controller 1 is configured to end the clock adjustment mode unless the clock key 20 is operated for a predetermined time (5 seconds in this embodiment).

Next, the operation of the control device 1 will be described in more detail with reference to FIGS.

First, the operation in the clock display mode will be described with reference to FIG.
The control device 1 detects the operation of the clock key 20 (step 3).

If the clock key 20 is off (step 33), the process returns to step 30 and if it is not off, it is determined whether the clock key 20 has been pressed for 2 seconds or more (step 34). To flash the minute display on the display 5 (step 35), and shift to the minute adjustment mode (step 36). If it is not pressed for 2 seconds or more in step 34, the process returns to step 33.

If the clock is being displayed in step 31, it is checked whether the clock key 20 has been turned off (step 37). If it is off, it is checked whether another key is on (step 41). The mode is ended (step 42), and the function control of another key is executed (step 43). If another key is not on, the process returns to step 30.

If the clock key 20 is not turned off in step 37, the operation for two seconds is detected (step 38). If the key is pressed for more than two seconds, the clock circuit 3 is controlled to blink the minute display on the display 5 ( Step 39), shift to minute adjustment mode (Step 4)
0).

 Next, the operation in the minute adjustment mode will be described with reference to FIG.

In this mode, the control device 1 checks whether the clock key 20 is on (step 50), and if it is on, increases the minute digit by one (step 51). Then, it is checked whether the clock key 20 is off (step 52). If it is off, the process returns to step 50. If not off, wait 0.5 seconds (Step 5
3) Increment the minute digit by one again (step 54). That is, the minute digit is increased by one every 0.5 seconds. Then, check that the clock key 20 is off again (step 5
5) If it is off, return to step 50. If it is not off, 150 msec elapses (step 56), and the minute digit is increased by one again (step 57). That is, in the future, the minute digit will be increased by one every 150 msec. Clock key 20 in step 50
If is not on, it is detected that there is no operation for more than 5 seconds (step 58), and the hour digit is made to blink (step 5).
9) The mode shifts to the hour adjustment mode (step 60). If 5 seconds have not elapsed in step 58, it is checked whether another key has been pressed (step 61). If it has been pressed, the adjustment mode ends (step 62), and a function corresponding to the other key is performed. Is performed (step 63). If no other key is pressed in step 61, the process returns to step 50.

 Next, the operation in the time adjustment mode will be described with reference to FIG.

In this mode, the control device 1 checks whether the clock key 20 is on (step 70), and if it is on, increases the hour digit by one (step 71). Then, it is checked whether the clock key 20 is off (step 72). If it is off, the process returns to step 70. If not off, wait 0.5 seconds (Step 7
3) Increment the hour digit by one again and return to step 72 (step 74). That is, here, the hour digit is increased by one every 0.5 seconds. If the clock key 20 is not turned on in step 70, it is detected that there is no operation for more than 5 seconds (step 7).
5) The blinking of the hour digit is released (step 76), and the mode shifts to the clock display mode (step 77). If 5 seconds have not elapsed in step 75, it is checked whether another key has been pressed (step 78), and if it has been pressed, the adjustment mode ends (step 79), and a function corresponding to the other key has been performed. (Step 80). If no other key is pressed in step 78, the process returns to step 70.
