Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic timepiece in which hours and minutes can be set in a clock circuit using 12 keys arranged in a ring.

Conventionally, the main method of setting the time on electronic watches has been a fast forwarding method, which requires a great deal of effort.

In addition, a system has been proposed in which 10 keys are used in combination with an electronic desktop calculator, but this method has the drawback of complicating the operating procedure and is troublesome.

The present invention solves the above-mentioned drawbacks of the conventional system, and consists of 12 keys arranged in a ring, with each key corresponding to an hourly and 5-minute key, and key operations in the setting mode are The first time is the hour input state, and the second is the minute input state, so that the hours and minutes can be easily set.

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

FIG. 1 is a plan view of a watch showing one embodiment.

The central display device DSP is composed of a liquid crystal or the like, and digitally displays hours, minutes, seconds, and AM/PM.

The figure shows 3:00 a.m. 1:47 seconds.

Note that this may be an analog display showing the time using a short hand and a long hand, and any display format may be obtained.

1□ is 1 on the dial of an analog clock.
They are arranged in a ring shape corresponding to the index No. 2, and serve as keys for inputting hours and minutes in time setting as described later.

Here, for convenience, a subscript indicating the input value at the time of 11 (on the left) and a subscript indicating the input value for the minute (on the right) are written together with a diagonal line above 11 for each of the numeric keys.

The function keys Kf and ~Kf4 are used to instruct various setting modes, and the KF1 key is used to set or modify the current time, and the KF2 key is used to set the alarm time.
The key Kf3 is used to set the alarm time, and the key Kf4 is used to set the timer time.

The fortune transfer key Km is a key for inputting morning or afternoon distinction in these time settings.

FIG. 2 is a main block diagram showing the parts related to setting or correcting the current time.

The hour information H, minute information M, etc. of the time register T are counted up as appropriate according to the time counter CO, which operates from a signal supplied from the clock generator CG via the frequency divider circuit DV, and is normally counted up by the display control unit DSC. It is displayed as current time information on the display device DSP via.

The key unit shows 11 as a whole in the number key Ko~ in Fig. 1, and information on the pressed key is encoded by the encoder EC.
The signal is input to the encoding register R via the counter C, and the number of times the key is pressed on the key unit is counted by the counter C.

Furthermore, the coded key information is stored in the code match detection circuit C.
A match with the encoded information of the key inputted to M and previously operated is detected.

The counter CR counts up the contents of the register R by one when a match is detected by the code match detection circuit CM.
If the contents of the register R at the time of coincidence detection are a specific value, the discrimination circuit JR sets the contents of the detection register R to a specific value accordingly.

The key manual control circuits IC, inhibit the input of coded key information to the register R when the code match detection circuit CM detects a match, and the time input control circuit IC2 and the hand input control circuit IC3 control the input of the coded key information from the register R to the time register. This controls the input to the hour information H section and the minute information M section of T.

The determination circuit JT determines the pressed state of the ff1l key Kf1.

Micro orders (2) and (2) are output when pressed or not pressed according to the judgment state of the discrimination circuit JT.

Also, micro orders ■ to ■ are output according to the count contents of counter C, and micro orders ■ are C≧
1. Micro order ■ is C = 0, micro order ■ is C
=1 and micro order ■ are output when C≧2.

First, when the closing key Kf1 is pressed, the micro order (2) is output from the pressed state determination circuit JT.

Here, since the contents of the counter C are C=0, the micro order ■ is also output.

Therefore, a control signal is applied to the display control section DSC via the AND gate A, and the hour digits on the display device DSP are displayed by blinking.

This indicates to the user that they are currently setting or modifying the hour digits.

Next, if you want to set or modify a desired key on the key unit, for example 9 o'clock, press the Conform key shown in FIG. Encoded key information is input into register R.

The encoder EC selectively encodes the key force using micro orders ■ and ■. Here, since the micro order ■ is input, the key force is encoded as corresponding to time information and is stored in the register R. is input.

Then, the counter C is incremented by one and becomes C=1 by this key input, so the micro order (■) is generated and the time input control circuit IC2 is turned on, and the contents of the register R remain unchanged in the time information H section of the time register T. will be forwarded to.

Also, since the counter C becomes C≧1, micro order ■ is output at the same time, and after that, another control signal is given to the display control circuit DSC via the AND gate A2, and the minute digit of the display device DSP blinks. This indicates that the minute digits are to be set or modified thereafter.

If a desired key in the key unit is pressed again here, the corresponding coded key information is input into the register R in the same way.

However, the encoder EC is added with the micro order (2) and encodes the key human power as corresponding to the minute information.

When the key is pressed for the second time, the counter C becomes C≧2 and outputs the micro order ■.

The output of this micro order ■ turns on the hand input control circuit IC3, and the contents of the register R are changed to the minute information M of the time register T.
At the same time, the time counter CO is reset and held by the control signal of the AND gate A3, which performs the AND of the micro-order and the ■.

If the same key is pressed again when setting or modifying the minute digits, this will be detected by the code match detection circuit CM, and the key human control circuit IC1 will be turned off to prohibit input to the register R, and the counter CR will be reset. The contents input to register R are counted up by one.

For example, when setting or modifying the minute digit, if 5 is pressed on the Kyoto key, coded key information corresponding to the contents of 25 is first input into register R, and then 5 is pressed on the same 11a key. Then, the counter CR counts up by one, and the coded information corresponds to the contents of 26.

Furthermore, if the number of times the same key is pressed is increased, the number of times the same key is pressed will be counted up.

The contents of these registers R are sequentially transferred to the minute information M part of the time register T via the intervention force control circuit IC3 which is turned on, and are transferred to the display device DSP via the display control unit DSC.
The minute digit is displayed with the blinking digit.

In this way, intermediate setting values or correction values not included in the key unit K can also be input.

Note that when the content of the last digit of register R corresponds to 4 or 9, the discrimination circuit JR detects this.If the same key is pressed again in this state, the color code CR will change the content of the bottom 1 digit of register R. Coded information corresponding to 0 or 5 is set in the digit according to the detected content.

That is, the same key is pressed five times to return to the initial value written on the key, and here settings or corrections can be made again using the same key.

In addition, unless the coded key information is the same, the key manual control circuit IC does not prohibit input to register R, so when setting or modifying the minute digit, it is necessary to use another key, for example, the key If 6 is pressed on the master key instead of 5, coded key information corresponding to 30 is input into register R anew.

When m key Kf1 is turned off, micro order (2) is output and counter C is reset.

Therefore, from this point on, the time counter CO resumes counting up, and the display device DSP displays a normal display without blinking.Of course, after setting or correcting the hour digits, immediately turn off the □ key Kf1. It is also possible to set or modify only the time.

The Fat Research Fee Hatake 1 key Km is not shown in Figure 2, but it can be manually operated while the Condom key Kf is pressed, and each time it is pressed, the AM and PM of the AM and PM information sections are reversed. do.

In addition, in the embodiment, when setting or correcting the minute digit, the same key on the key unit is pressed the desired number of times to set or correct the intermediate value, but if the same key is continued to be pressed, the count is automatically increased. There is no harm in doing so.

Also, in Figure 2, we only talked about setting the current time, but
It can be implemented in the same way in other modes as well.

As described above, according to the present invention, hours and minutes can be set in the clock circuit using 12 keys arranged in a ring, and the input value of each key can be intuitively understood, and is used to set the hours and minutes, making it easy to operate and set the hours and minutes.

In particular, according to the present invention, when inputting intermediate minute data such as 28 minutes, after operating the key corresponding to 25 minutes on the analog clock (key 5 in Figure 1),
Since you only have to press the same key three times, you can input data very intuitively and smoothly.Furthermore, there are no extra keys for minute data entry like with a manual numeric keypad, so you don't have to worry about confusing key selections. This has the great effect of preventing erroneous input.

Furthermore, it is not necessary to specifically print characters indicating hour and minute values on the key, and an electronic timepiece with high practical value can be provided.
