Abstract

PURPOSE:To eliminate the necessity of time setting operation at the time of releasing power saving mode without complicating the constitution by driving an hour and minute hand and a second hand by separate motors and providing the power-saving mode of return function type only in the second hand. CONSTITUTION:When the mode is changed from the timing operation mode of the second hand, which is a normal mode, to a timer mode by operating a switch 14B for timer mode of a switching circuit 14, a second hand 13 is driven by quick feed, and when time set by a timer is arrived, the second hand 13 is stopped by a signal from a timer function circuit 21 and becomes a second hand stop mode. When the second hand 13 is returned to a timing operation mode by operating the switch 14B for timer mode, the second hand is driven by quick feed, and arrival at present time is detected, and the second hand 13 is changed to a timing operation mode by a signal from the circuit 21. Thus, in a timer mode (power saving mode) very small current consumption is kept as a two-hand clock for hour and minute, and when the second hand is stopped, information is stored by the counter, are returned to the present time when the timer mode is released based on information of the counter.

[Problem that the invention seeks to solve]

The conventional power saving mode described above is a general type that stops the power supply to the entire circuit, and is easy to configure and widely adopted. It is necessary to perform the time adjustment operation after returning to the normal operation mode. In the case of the return function type shown in Fig. 4, the time adjustment operation after returning to the normal operation mode is not necessary. Requires a counter with storage capacity for hours,
Furthermore, in order to return all the hour, minute, and second hands, it is necessary to perform fast-forward correction for up to 12 hours, which has the disadvantage of increasing the size of the counter structure and requiring too much time for correction, which is why this practice has not been carried out. .

10 is a second switching circuit, which is connected to the timing pulse generation circuit 1;

Next, the operation of the multifunctional analog electronic timepiece having the above configuration will be explained.

First, in the normal time function state, the function selection circuit 27
is in a non-selected state and the control signals PCI and PC2 are not output, so the first switching circuit 5 and the second switching circuit 10 are in a state of selecting the minute hand drive pulse PT and the second hand drive pulse Pa2, respectively. As a result, the display device 8 displays the normal time by moving the hour and minute hands 9 in steps of 20 seconds and the second hand 16 in steps of 1 second. Consider the case where the timer function is used in this state. First, when the timer switch section 14B is operated to switch the second hand 13 from the normal seconds display mode to the timer mode, the timer switch section 1
The false timer switch signal from which the timer switch signal is outputted from 4B is supplied to the second hand function selection section 27B, thereby generating the second switching control signal Pc2, which causes the second switching circuit 10 to select the timer function signal PM2. Switch settings to the state.

Then, the second hand 1.6 moves in fast forward direction from the current second to the O second position (12 o'clock direction), which is the timer mode, in accordance with the timer function signal PM2 via the second drive circuit 11 and second motor 12. do. The timer switch signal is also supplied to the timer function circuit 21, which counts the difference between the current second and the O seconds position and outputs a drive pulse corresponding to that number as the timer function signal PM2.

Then, the second hand 1ro reaches the O second position and stops. Next, when the switch for starting the timer is operated, the timer switch e14B outputs a timer switch signal for starting the timer. Then, the timer switch signal is supplied to the timer function circuit 21, and the timer set drive panel is activated by the timer function signal P.
By outputting M2, the second hand 16 is fast-forwarded and can be set at the desired timer setting time. Next, when a switch operation for starting the timer is performed, a timer switch signal for starting the timer is output from the timer switch section 14B.

In response to the timer switch signal, the timer function circuit 21 starts timer counting in 1-minute steps, and in order to display the remaining time on the second hand 16, a drive pulse is sent to the timer function signal P□2 every minute. The timer function is performed by outputting the second hand 13 and moving the second hand 13 through the second switching circuit 10, the second actual operation circuit 11, and the second motor 12.

Then, when the timer function circuit 21 detects that the timer count has timed up, the timer sound control in the timer function circuit 21 is activated to generate a °C timer sound. Occur.

Even while the timer operation is performed using the second hand 16 as described above, the hour and minute hands 9 function as a two-hand watch because they are driven by the minute hand drive pulse PMl.

However, since the above-mentioned timer function requires an operating time of 60 minutes, it may be desirable to set an alarm, which is another function, during the operating period. The present invention satisfies the above desire, and its operation will be explained below.

That is, by operating the alarm switch section 14A to monitor the alarm setting time even when the timer is operating, an alarm switch signal is supplied to the function selection circuit 270 to the hour and minute hand function selection section 2; IAVC. As a result, the hour/minute switching control signal Pc1 is generated, and the procedure 1 switching circuit 5 is switched to the selected state of the alarm function signal PM. Then, through the first drive circuit 6 and the first motor 7, the hour and minute hands 9 are moved in fast forward motion from the normal time to the alarm setting time in accordance with the alarm function signal PMI.

In addition, the alarm switch signal is sent to the alarm function circuit 15.
At this time, the difference between the normal time and the alarm setting time is counted, and drive pulses corresponding to that number are outputted as the alarm function signal PM1. Then, the hour and minute hands 9 reach the alarm setting time and stop.

Furthermore, in this state, the alarm switch section 14A'&
By operating it, you can reset the alarm time and return to time mode.

As mentioned above, since the control systems up to the first motor 7 and second motor 12 for driving the hour and minute hands 9 and the second hand 13, respectively, are completely independent, alarm functions and timer functions are added to each. has become completely independent.

That is, when displaying the electronic timepiece of the present invention at a store, the timer mode is set by operating the timer mode switch ST, and if the timer is left without operating, the timer mode becomes the power saving mode.

In this power saving mode, the hour and minute hands measure time using the signal PT1 with a 20-second period, thereby maintaining timekeeping operation with extremely low current consumption as a two-hand watch with only an hour and minute counter, and also reducing current consumption. In many cases, the second hand stops its operation and stores information using a counter, and when the timer mode is released, the current time is returned to the current time based on the counter information.

Therefore, the storage counter may be one revolution of the second hand, that is, a sexagesimal counter, and since the return correction can be made within one revolution of the second hand, the time required for fast forward correction is also extremely short.
