Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic timepiece that has an electronic oscillation circuit and uses the oscillation frequency as a time standard, and is capable of storing the current time.

The present invention relates to an electronic timepiece that can store the time at any given time by incorporating a memory circuit into the electronic timepiece.

An object of the present invention is to make an electronic watch easier to use by providing the electronic watch with a function of memorizing the time at any given time.

Conventional electronic clocks have been inconvenient because they cannot store the time at an arbitrary time.

The electronic timepiece according to the present invention eliminates such drawbacks and is capable of storing the time at any desired time and displaying the stored time at any time after that time.

Furthermore, the currently displayed time will not be distorted by storing the time.

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is an electrical configuration diagram of an embodiment according to the present invention.

In FIG. 1, the output of an oscillation circuit 1 is frequency-divided by a frequency divider circuit 2, and an IHz signal is input to a second counting circuit 3.
Seconds are counted.

The second counting circuit outputs a signal every 60 seconds, which is manually input to the minute counting circuit 4 to count the minutes.

The minute counting circuit outputs a signal every 60 minutes, which is manually input to the clock counting circuit 5 to count the hours.

The hours, minutes, and seconds counted in this way are usually set to switch 1.
4, 15, and 16 are closed, so they are displayed on the display device.

The above is the mechanism of a normal electronic watch, but the electronic watch according to the present invention has the memory circuits 6, 7, 8, electronic switches 11, 12, 13, 17, 18, 19 and these electronic switches in addition to the normal electronic watch. It is characterized by the addition of a control circuit 10.

When the external switch 20 is closed, the control circuit 10 closes the switches 17j8, 19 for a short period of one second or less, and the hours, minutes, and seconds at that time are stored in the memory circuits 6, 7.8.

Next, when the external switch 2] is closed, the control circuit 10
Switches 14, 15, and 16 are opened, switches 11, 12, and 13 are closed, and the previously memorized hours, minutes, and seconds are displayed on the display device 9.

In this way, at any given time, the time can be stored inside the electronic watch and displayed at any given time.
