Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a time setting method for an electronic analog display timer that has a plurality of bar display elements and displays the timer time according to the number of bar display elements displayed, and particularly relates to a timer to be set. The timer time is set and displayed by touching the bar display element, which is unnecessary for displaying the time, with a finger.

2. Description of the Related Art Conventionally, there is an electronic analog display timer that has a plurality of bar display elements and displays a timer time according to the number of bar display elements displayed. To set the timer time with this timer, use a mechanical switch installed on the exterior of the watch.
A method is used in which a constant pulse signal is supplied to a timer counter that counts the timer time to count the timer setting time. Then, when the number of bar display elements corresponding to the timer setting time is turned on, and the timer is then operated, the timer counter is counted down, and accordingly, the bar display elements are turned off one after another. When the set time arrives, all the bar display elements disappear, and at the same time, a connected external device, such as a notification circuit, is driven to generate a notification sound.

However, this conventional setting method using a mechanical switch has problems in that when the timer time is long, the setting takes a long time and is difficult to operate.

The present invention has been made to solve the above-mentioned conventional drawbacks, and its purpose is to provide a timer time setting method that is easy to operate and does not take much time.

In order to achieve the above object, the present invention provides a touch switch on all the bar display elements, lights up all the bar display elements when the timer time can be set, and sets the timer among the lighted bar display elements. By sequentially touching the touch switches on the bar display elements that are not necessary for time display, the bar display elements are sequentially turned off and the timer time is set.

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

FIG. 5 shows a block circuit diagram for realizing the above operation.

In the figure, a reference signal generator 10, a frequency dividing circuit 1
Reference numeral 2 denotes a circuit that divides the frequency of the reference signal to generate a constant periodic signal necessary for timer timing. The timer counter 14 counts the set timer time using the constant periodic signal, and in this embodiment, 60 flip-flops (hereinafter referred to as FF
). The FF14-0 to 14-59
The signals of each output Q of each FF are connected to the bar display elements 2-0 to 2-59 via the driver 16, and when the signal of the output Q of each FF rises to H, the bar display connected The element is configured to light up.

On the other hand, the setting mode switching circuit 18 is a circuit that switches the timer from the normal mode to the time-time settable mode or from the timer time settable mode to the normal mode by switching the external switch 20. This setting mode switching circuit 18 is FF
22, consists of a one-shot circuit 24, and the output signal of the one-shot circuit 24 is sent to the timer counter 14.
The signal from the output Q of the FF 22 is input to the timer time setting circuit 26.

The timer time setting circuit 26 consists of 60 AND gates 28, OR gates 30, and 59 AND gates 32, and each OR gate 30-0 to 30
-59 are FF1 of timer counter 14 respectively
It is input to the reset inputs 4-0 to 14-59. Each touch switch 4-0 to 4-59 is connected to one of the inputs of each AND gate 28-0 to 28-59, and the other input is connected to the FF 22.
The signal of output Q of is input. Further, a constant periodic signal from the frequency dividing circuit 12 is input to one input of each AND gate 32-0 to 32-58. and ANDGATE 32-0 and ANDGATE 2

Further, in this embodiment, a notification sound generation circuit 34 that generates notification sound is used as an external device, and the signal of the output of the FF 14-0 is applied to this notification sound generation circuit 34 via an AND gate 36. has been done. This AND gate 36 and an AND gate 38 to which the output signal of the frequency dividing circuit 12 is input.
A timer ON/OFF switch 40 is connected to the timer for controlling start and stop of the timer operation.

The operation of this circuit will be explained below.

When the contact piece 20a of the external switch is connected to the contact point 20b, the signal of the output Q of the FF 22 becomes H, all the AND gates 28 are opened, and the touch switch 4 is enabled. At the same time, a positive single pulse is generated from the one-shot circuit 24, setting all the FFs 14 and making their output Q high. As a result, as shown in FIG. 4, all the bar display elements 2 are lit.

After that, when touch switch 4-59 is touched, the H signal is input to reset input R of FF14-59 via AND gate 28-59 and OR gate 30-59, resetting FF14-59, and outputting Q. signal to L, output signal to H
shall be. As a result, the bar display element 2-59 goes out and the AND gate 28-59 opens. After that, when you touch touch switch 4-59, the H signal goes to AND gate 28-58 and OR gate 30-5.
8 to reset input R of FF14-58 to reset FF14-58. As a result
The output Q signal of FF14-58 becomes L, the output signal becomes H, and the bar display element 2-58 turns off.
AND gates 28-57 and 32-57 open. In this way, from bar display element 2-59, 2-5
Touch switches 4-59, 4 placed on the front cover glass corresponding to positions 8, 2-57...
-58, 4-57..., the light goes out from the bar display element 2-59 to the bar display element located at the position of the touch switch last touched.

As shown in FIG. 4, when the touch switches 4-59 to 4-41 are touched, the bar display elements 2-59 to 2-41 go out and the AND gate 2
8-40 and 32-40 are in an open state.

After that, when the contact piece 20a of the external switch 20 is connected to the contact point 20c and the timer ON/OFF switch 40 is closed, the AND gates 36 and 38 are opened and a constant periodic signal is transmitted to the AND gates 32-0 to 32-0.
-58 and or gate 30-59.
Since the AND gates 32-40 to 32-58 are open at this time, constant period signals are input to the FFs 14-40 to 14-59. Then, when the constant period signal rises to H, FF14-40 is reset,
The bar display element 2-40 is turned off, and the AND gates 28-39 and 32-39 are newly opened. After this, when the constant periodic signal rises again, FF14-39 is reset and new AND gates 28-38, 3
2-38 opens. In this way, every certain period of time
The FF 14 is reset from the upper level, and the bar display elements are sequentially turned off accordingly. Finally FF1
4-0 is reset, the output Q signal becomes L, turning off the bar display element, and the output signal becomes H, which drives the notification sound generation circuit 34 to generate a notification sound to notify the user. Notifies you that the set time has arrived.

In this way, according to this embodiment, when setting the timer time, all the bar display elements are turned on first, and unnecessary bar display elements are touched sequentially from the top to display the set time. The bar display element turns off and the required timer time is set.
Therefore, the conventional mechanical switch used for setting the timer time is unnecessary, and the operation is much simpler and less time consuming than the conventional one.
Further, since the timer time is not set unless the bar display elements are touched in order from the top, even if other bar display elements are inadvertently touched in the settable mode, no malfunction will occur. Furthermore, even if you set the timer time incorrectly, simply connect the contact piece 20a of the external switch 20 to the contacts 20a to 20b, and then connect it again to the contact 20b, and the timer counter 14 will start again.
The FFs 14-0 to 14-59 are set, and the bar display elements 2 are all turned on to return to the initial time setting possible state. Also, if you close the timer ON/OFF switch 40 without touching the bar display element 2,
The timer time can be set to the maximum settable time of the timer counter 14.

In the present embodiment, the present invention is applied to an electronic analog display timepiece in which the display section has a plurality of bar display elements arranged at equal intervals on the circumference, but as shown in FIG. It is also possible to use it in an electronic analog display timer in which elements are arranged in parallel, producing similar effects.

As described above, according to the present invention, the required timer time can be set in a very simple way by touching the bar display that is unnecessary for setting time display, and the timer time setting can be performed as before. Mechanical switches are also no longer required. Furthermore, since the bar display elements go out in the order in which they are touched, it is easy to understand the set time, and there are many advantages such as no malfunction will occur even if a bar display element is touched in the middle.
