Description

[Detailed description of the invention] The present invention provides an electronic watch with an alarm that generates a notification sound at a preset alarm time, which forcibly displays the alarm time for a certain period of time when the alarm is set, and By making it possible to modify the alarm settings, the operation of the alarm set is simplified.

2. Description of the Related Art Conventional electronic watches with alarms use a method in which the alarm time and the current time are switched and displayed on the same display section. This has the advantage of not requiring a complicated display, but if you are going to perform an alarm set operation, first display the alarm time on the display using a display changeover switch, etc. Sometimes, the alarm time can be modified using the modification mode changeover switch, and then the alarm time is modified using the modification switch. When the alarm time reaches the desired time, the correction mode changeover switch disables modification of the alarm time, and the alarm set/non-set switch sets the alarm. Finally, the display changeover switch causes the display unit to display the current time again.

As described above, in the conventional alarm setting operation, it is necessary to operate four switches: a display changeover switch, a correction mode switch, a correction switch, and an alarm set/non-set switch, making it extremely difficult to use.

Therefore, improvements have been made in the past to simplify this alarm setting operation, so that the display changeover switch changes the time displayed on the display and also changes the correction mode, thereby omitting the correction mode changeover switch and its operation. was proposed. However, the alarm setting operation still required the operation of three switches: a display changeover switch, a correction switch, and an alarm set/non-set switch, and there were still problems in terms of ease of use.

The present invention eliminates the above-mentioned conventional drawbacks, and its purpose is to provide an electronic timepiece with an alarm that is easier to operate.

In order to achieve the above object, the present invention forcibly displays the alarm time on the display section for a certain period of time when the alarm is set using the alarm set/unset switch, regardless of what was previously displayed on the display section. It is also characterized in that the alarm time can be adjusted.

Embodiments of the present invention will be described below based on the drawings.

The operation of this circuit will be explained below.

When the alarm set/unset switch 28 is open and the alarm is in the unset state, and the contact piece 46c of the display changeover switch 46 is closed to the contact 46a side, the signal from the contact 46a becomes H, and the mode display element 24a becomes The light is turned on, AND gates 36 and 40 are opened, and AND gates 44 and 38 are closed.

Therefore, the current time signal from the clock circuit 6 is input to the display section 18 via the AND gates 36 and 40 and the decoder/driver 8, and the current time is displayed on the time display section 20. Also alarm set mark 2
2 is not displayed because the alarm set/non-set switch 28 is open.

When the contact piece 46c of the display changeover switch 46 is connected to the contact point 46b, the signal from the contact point 46b becomes H, the mode display element 24b lights up, and the AND gate 44 is opened instead of the AND gate 40 closed. becomes. Therefore, the alarm time signal from the alarm time storage circuit 10 is input to the display section 18 via the AND gate 44, the OR gate 42, and the decoder/driver 8, and the alarm time is displayed on the time display section 20.

When the alarm set/non-set switch 28 is closed while the contact piece 46c of the display changeover switch 46 is connected to the contact 46a, the output signal of the switch 28 changes from L to H, and the AND gate 26 becomes open. The alarm set mark 22 lights up. As the output from the alarm set/unset switch 28 rises, the signal at the output Q of the flip-flop 30 changes from L to H, and the output signal changes from H to L. As a result, the reset of the decimal counter 34 is released and the constant period signal φ ₁ (1 Hz) from the frequency dividing circuit 4 starts counting. Also, the output Q signal changes from L to H.
As a result, the AND gate 36 is closed and the AND gate 38 is open, so that the alarm time signal from the alarm time storage circuit 10 is transmitted to the display section 18 via the AND gate 38, the OR gate 42, and the decoder/driver 8. The alarm time is displayed on the time display section 20. In this state, the mode display element 24a remains lit, unlike when the mode display element 24a is switched by the display changeover switch 46. After 10 seconds in this state, the output Q signal of the decimal counter 34 changes from L to H.
stand up and reset the flip-flop 30. This causes the output Q of flip-flop 30 to be
The signal changes from H to L, and the output signal returns from L to H. Therefore, the decimal counter 34 is reset, the AND gate 38 is closed, and the AND gate 36 is closed.
is in an open state, the current time signal from the clock circuit 6 is input to the display section 18 via the AND gates 36 and 40 and the decoder/driver 8, and the current time is displayed on the time display section 20 again.

By the way, the contact piece 46c of the display changeover switch 46
When connected to the contact 46a, the AND gate 58 is opened and the AND gate 62 is closed. When the correction lock switch 56 is closed, the output of the AND gate 66 becomes H, and the output of the AND gate 70 becomes H.
is closed, and the AND gate 64 is in the open state,
The current time can now be adjusted. When the correction switch 48 is opened or closed, a pulse signal is generated from the output of the chattering prevention circuit 50, and the pulse signal is input to the clock circuit 6 via the AND gates 52, 58, 64 and the OR gate 72, and the current time is set. Corrections are made.

When the contact 46c is connected to the contact 46b of the display changeover switch 46, the alarm time is displayed on the display unit 18 as described above. At the same time, the AND gate 58 is closed and the AND gate 6 is closed.
Therefore, if the correction lock switch 56 is closed and the correction switch 48 is opened and closed, the pulse signal generated by the chattering prevention circuit 50 will be output to the AND gates 52 and 62.
The signal is input to the alarm time memory circuit 10 via the START/STOP function, and the alarm time is corrected.

The contact piece 46c of the display changeover switch 46 is connected to the contact 46a, and when the alarm set/non-set switch 28 is closed to set the alarm, the display section 18 shows the alarm time for 10 seconds as described above. only displayed. In this state, the output Q of the flip-flop 30 is H and the output is L, so the AND gate 58 is closed, and the H signal of the output Q is input to the AND gate 62 via the OR gate 60, so the AND gate 62 is open. Therefore, when the correction lock switch 56 is closed and the correction switch 48 is opened/closed, the pulse signal is sent to the alarm time storage circuit 10 via the AND gates 52 and 62.
is input and the alarm time is corrected. Further, the pulse signal is applied to the reset input R of the decimal counter 34 via the OR gate 32, and the count contents of the decimal counter 34 are cleared each time the correction switch 48 is closed, so that the correction operation is not necessary. The alarm time continues to be displayed on the display unit 18 while this is being performed. Then, 10 seconds after the correction is completed and the correction switch 48 is opened, 10
The advance counter 34 resets the flip-flop 30 so that the output Q becomes L and the output becomes H. Therefore, the current time is displayed on the display unit 18 again, the AND gate 62 is closed, and the alarm time is no longer adjusted.

2A, 2B, 2C, and 2D are display format diagrams of the display section 18 according to an embodiment of the present invention.

FIG. 2a shows the display form when the contact piece 46c of the display changeover switch 46 is connected to the contact 46a when the alarm is not set. Mode display element 24
a lights up, and the time display section 20 displays the current time, 7:00 am. In this state, the current time can be corrected, and the current time can be corrected by closing the correction lock switch 56 and opening/closing the correction switch 48.

FIG. 2b shows the display form when the contact piece 46c of the display changeover switch 46 is connected to the contact point 46b when the alarm is not set. This time, the mode display element 24a goes out, the mode display element 24b lights up, and the alarm time of 8:30 a.m. is displayed on the time display section 20. In this state, the alarm time can be corrected, and the alarm time can be corrected by closing the correction lock switch 56 and opening/closing the correction switch 48.

Figure 2c shows the contact piece 46c of the display changeover switch 46.
The case is shown in which the alarm set/non-set switch 28 is closed while the alarm is connected to the contact 46a.

In this state, the mode display element 24a continues to light, indicating that the current time is displayed.
The time display section 20 shows the alarm time of 8 a.m.
30 minutes is displayed and the alarm set mark 22 lights up to indicate that the alarm is set. While this alarm time is displayed, the alarm time can be adjusted, and the adjustment lock switch 5
6 and open/close the correction switch 48, the alarm time can be corrected. Then, 10 seconds after opening the switch 48 after the correction is completed, the second
As shown in FIG. d, only the time display section 20 switches from the alarm time to the current time display, and the current time can be corrected. If no correction is made, the alarm time will similarly switch to the current time 10 seconds after the alarm time is displayed.

According to this embodiment, when the alarm is set by the alarm set/non-set switch 28, the alarm time is forcibly displayed for a certain period of time regardless of what is displayed on the display section 18 at that time. At the same time, the alarm time can be adjusted. Therefore, when operating the alarm, simply close the alarm set/non-set switch 28, then close the correction lock switch 56 and open/close the correction switch 48 to adjust the alarm time. It becomes very easy to operate. Once the modification is complete
Since the alarm time display automatically returns to the current time display after 10 seconds, there is no need to operate the display changeover switch 46 as in the conventional case. Furthermore, in this embodiment, each time the correction switch 48 is closed, the count contents of the decimal counter 34 that controls the time for displaying the alarm time are cleared, so the alarm time display and the time available for correction are extended. The display will no longer switch to the current time or the alarm time will no longer be adjustable.

In this embodiment, the modification is performed by the modification switch 4.
Although the pulse signal generated by opening and closing the frequency dividing circuit 8 was used, it is also possible to use a constant periodic signal from the frequency dividing circuit 4.

As described above, according to the present invention, by setting the alarm to the set state using the alarm set/unset switch, the alarm time is forcibly displayed on the display section for a certain period of time regardless of what is displayed on the display section. By displaying the alarm time and making it possible to adjust the alarm time, the alarm setting operation can be performed using only the alarm setting/non-setting switch and the correction switch, making the operation easier and simpler.
