Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electronic timepiece in which time data such as a timer and time can be easily set.

[Prior art]

Conventionally, with mechanical evening timers, the dial knob is rotated clockwise to set the hands at the desired time position on the scale plate, and once the setting is complete, the hands are moved counterclockwise as time passes. As it rotates, the position of the needle reaches the scale “0” again.
'', that is, after the timer has elapsed for one hour, a predetermined alarm sound is sounded.

On the other hand, in the case of a child-type timer, there are multiple buttons for inputting one hour of the timer, a display section for numerically displaying one hour of the timer, and a start button for starting the timer operation. It is being

The set time displayed on the display section at the time of setting is subtracted and displayed after the timer operation starts.

[Problems with conventional technology]

In the case of a mechanical timer, the set time is not maintained, so even if the same timer is used for one hour continuously, it must be set again, which is cumbersome.

On the other hand, in the case of an electronic timer, setting the timer to one hour has the disadvantage that the button for inputting the time must be operated multiple times, which is cumbersome.

(Object of the invention) This invention was made against the background of the above-mentioned circumstances.
The purpose is to provide an electronic timepiece in which time data can be set by a simple operation of a switch.

[Key points of the invention]

This invention generates time data such as one hour timer, clock time, and alarm time, and sets the generated time data in the time measurement means, depending on the set position of a dial type switch, slide type switch, or the like.

[First Embodiment] Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. It is an electronic watch that also performs timekeeping operations.

FIG. 1 is a plan view of the electronic timepiece. In the figure, a display section 2, a dial switch 3, a changeover switch 4, a start key 5, and a sound emitting hole 6 are provided at the center of the upper surface of the case body 1. In addition, the case body 1 is provided with various electronic circuit components, a buzzer, a battery, etc., for performing normal timekeeping operations, evening/timer timing operations, and display and sound emission operations. There is.

The display section 2 is composed of, for example, a liquid crystal display device, and as shown in the figure, the left side thereof has a number display, a colon display, and an AM display.
, PM are used to display the current time, while on the right side, a number and a colon are used to display one hour of the timer (time data). In other words, the current time and the timer hour are each displayed separately at different positions within the display section 2 at all times.

The dial switch 3 consists of a switch body 3A embedded and fixed in the case body 1, and a knob 3B that is rotationally driven together with the switch body 3A. That't
As shown in FIG. 1, the recesses on the periphery of the switch body 3A on the case body 1 are marked with "OFF", "1", "2", . . .
..., scales up to "1o" are provided at equal intervals. In this case, when the selector switch 4 is set to "10", the dial switch 3 forms a 10-minute timer, which means 1. The timer of the OO minute meter is formed and the maximum l.

You can set the timer up to 0 minutes. Note that after the dial switch 3 is set to a desired position by rotating the knob 3B, the set position is mechanically maintained until the dial switch 3 is next operated to change the set position.

The start key 5 is a key to be operated when using the timer that has already been set for one hour without changing it.
By operating the start key 5, the set time is set in a timer counter, which will be described later, and the timer starts counting.

Next, the circuit configuration of a part of the timer of the electronic watch will be explained with reference to FIG. The contacts of the dial switch 3 are one movable contact body 3c and five fixed contact bodies 3D.

~3D, made of spikes. Therefore, the fixed contact body 3D1~
The circles attached to 3D indicate the respective fixed contacts, and in particular, "0FFJ,""1",
The fixed contact bodies 3D1 and 3D2 to 3Dg are connected by moving the movable contact body 3c over the positions indicated as "2", . . . , and "10", respectively. Further, the fixed contact bodies 3D, ~3D11 are arranged concentrically, and the scales are "0FFJ, r'lJ, r2J...1~IQ
By rotating the respective positions of J by 3°B, the fixed contact bodies 3D1 and the corresponding fixed contact bodies 3D2 to 3D are connected, and the result is "0" in decimal notation (i.e. "0").
FFJ), "1", "2", . . . , each data of rlOJ is set.

The shift register 10 has a 6-bit color capacity and takes in the clock OA with a period of 1 second as "1" data at a binary logic level in its first bit (LSB). That is, the clock frequency is higher than that of the clock signal, and the phases are 180 degrees different from each other l6.
The shift register 10 performs a shift operation to the upper side using the clocks p, s as a read clock and a read clock, respectively.

The 1st, 2nd, 3rd, and 4th bits are connected to the fixed contact bodies 3D2, 3D3, and 3D, respectively.
4. Each input side of 3D5 is connected, and the input side of changeover switch 4 is connected to the 5th bit. As a result, clock door A of II and II is connected to shift register 1.
After being taken into the first bit of 0, the data is shifted to the upper bit side, whereby each contact of the fixed contact bodies 3D2 to 3D6 and the changeover switch 4 is scanned. Further, the output from the 6th bit (MSB) of the shift register 10' is input to the AND gate 11. This antogenide 1
A clock door is inputted to the other end of 1, and the output of σ becomes a signal GB. ' On the other hand, the output side of the fixed contact body 3D is connected to the first bit of the shift register 2 having a capacitance of 5 bits. This shift register 12 is also driven by a clock 961, 7, and the 4-bit data is input one bit at a time from the contacts of the lower bit of the dial switch 3 and one bit sequentially from the changeover switch 4 at the first bit. Then, 1-bit data is taken in while being shifted sequentially to the upper bit side. A latch 13 with a capacitance of 5 bits is connected to the output side of the shift register 2.The latch 13 receives the signal 96B from the shift register 2.
Latch the 5-bit data from 02 and then clock 02
The 5-bit data is outputted and inputted to the input terminals of the 5-bit capacitor latch 14 and the mismatch detection section 15, respectively. Latch 14 receives signal 2. (described later) causes latch 1
The 5-bit data from No. 3 is latched, and the latched data is output when the clock 962 is input, and is input to the B input terminal of the mismatch detection section 15 and the decoder 17, respectively.

When the input data to the A input terminal and the B input terminal do not match, the mismatch detection section 15 outputs a mismatch signal yc of binary logic level "°1" and inputs it to the signal generation circuit 16. On the other hand, the signal generation circuit 16 receives a clock 961, a clock 961, and a mismatch signal Da.

The signals G, DS, EX, and F, which are both driven in synchronization with the clock z+, are output in this order.

Further, the decoder 17 decodes the latch data from the latch 14 and inputs the data (timer one hour) to the timer one hour storage section 18 according to the contents, and outputs a signal. Stored when outputting. The timer one hour storage section 18 also outputs a signal for the timer one hour.

When input through the OR gate 19, the timer counter 20, which is a subtraction counter, is reset. After the timer 14j is preset, the timer counter 20 receives its contents for 11 seconds through the AND gate 21 every time the clock OA having a period of 1 second is input. Then, when the count output is "0", that is, one hour has elapsed from the timer, the signal clock OR is outputted and inputted to the sound alarm section 25, and the buzzer is driven to generate an alarm sound.

On the other hand, a voltage VDD of °°1 level is applied to the input side of the start key 5 for continuous use of the already set timer IJi[, and one end of its output side is grounded (“0” level). One-shot circuit
ll Connected to N-22. The signal 968 output from the one-shot circuit 22 when the start key 5 is operated is input to the timer counter 20 via the OR gate 19, and the timer value is reset to the timer counter 20, and at the same time, the signal 968 is sent to the SR type flip-flop 24 via the OR gate 23. It is input to the set input terminal S of , and is set. The signal χF is also input to the set input terminal S of this flip-flop 24 via the OR gate 23, and its set output signal is the gate control signal of the AND gate 21. Furthermore, the clock O
R is input to the reset input terminal R of the flip-flop 24 and is reset.

Next, the operation of the first example will be explained with reference to the time chart of FIG. If we now set the timer In to 3 minutes, turn the selector switch as shown in Figure 1.
Set the 10-minute timer to "10" and then turn the knob 3B of the dial switch 3 from the "0FFJ" position to the "3" position. In this case, in the circuit diagram of FIG. 2, the movable contact body 3C is moved from the position t-' OF F j shown on the fixed contact body 3D to the position "3" and set. After this set, when a clock 96A (“1”) with a period of 1 second is output, it is read into the 1st bit of the shift register 1o when the clock signal is output, and then when the clock z2 is output, it is read into the 1st bit of the shift register 1o, and then when the clock z2 is output, it is shifted to 2 bits 1441\\. and the fixed contact body 3
°゛1゛1゛ signal is sent to D2.

Therefore, the fixed contact body 3D2 first outputs a "1°" signal, which is read into the first bit of the shift register 12.

The Il, 11 signal is shifted to the second bit of the shift register 12 when the clock signal 2 is output. The above period is shown as "C1" as the output of the shift register 10 in the time chart of FIG.

The period of “C2” during which the bit is shifted from the 10th output of the shift register to the 3rd bit,
The "1" signal is supplied to the fixed contact 3D3, and the fixed contact 3D3 outputs the "1" signal, which is input to the 1201st bit of the shift register.

Therefore, the data in the shift register 12 is “0001
1j (written from the upper bit side).

Furthermore, there are periods "C3" and "C4" in which "'1" signals are sequentially output to the 3rd and 4th bits of the shift register 10(1).
”, fixed contact body 3 D4.3 D5 sequentially °“
1" signal is supplied. In the position "3", the fixed contact of the fixed contact body 3D4.3Ds is not provided, so the "'0" signal is outputted to the shift register 12. Input to the 1st bit, II I I
When the period "C6" is reached where the signal is shifted I times, the
” signal is input to the selector switch 4, and in this case, “1
Since selector switch 4 is set to "0", °'0"
A signal is output and input to the 1st bit of the shift register 12, and its content becomes rllooOJ. Furthermore, the period “
C6'' and the 6th bit of shift register 10 is °'1.
``When the signal is shifted, the signal 9 is shifted from the AND gate 11.
6BF"1') is output. Therefore, shift register 1
The data rllooOJ in 2 is latched in the latch 13, and then input to the latch] 4 and the input terminal 15 of the discrepancy detection unit 1508 at the output of the crofter.

By the way, as mentioned above, the timer 1 time is set to 3 minutes, the clock is outputted, and the period 1"C+
Until J~'reel elapses, the output of the latch 14 is I because the timer was previously set to 1"0FFJ.
Q: OOOOJ. Therefore, in the period up to now, the data "ooooooJ" has been input to both the input terminal and the B input terminal of the discrepancy detection section 15, and the discrepancy signal 9bc has been inputted manually.
0 "I match). After outputting the signal 96B, the above-mentioned data f'1lo00J is sent to the ball input terminal.
is manually input, the discrepancy signal c is inverted to '1' (mismatch) and is input to the signal generation circuit 16. Therefore, the signal generation circuit 16 sequentially generates '1' signals 96D%5'E, 〆, 3 is output and sequentially input to the Z latch 14, the timer one-hour memory 18, and the timer counter 20.When the signal D is output, the data +11000J from the other switch 13 is latched. 14, mismatch detection unit 150B input terminal, decoder 1
7. Each is input. Therefore, the mismatch signal Oc is again inverted to "θ" (coincidence), and the decoder 17 outputs the timer one hour (3 minutes) corresponding to the data "11000J" and inputs it to the timer one hour storage section 18. This timer one hour is recalled to the timer one hour storage section 18 when the signal zF is output.Next, the timer value is preset to the timer counter 20 when the signal zF is output.

The one hour (3 minutes) of this timer is displayed on the display section 2 as shown in FIG. Now flip-flop 24
is in the set state and the AND gate 21 is opened. Therefore, from the time the second clock 96A is output, the timer counter 2o+; ar-i seconds starts to be subtracted. Then, until the timer one hour (three minutes) elapses, the timer one hour (three minutes) is sequentially subtracted and displayed on the display section 2. However, the knob 3B of the dial switch 3 remains set at the "3" position and does not change. When one hour (3 minutes) of the timer elapses, the timer counter 20 outputs a signal 91t, the buzzer of the sound part 25 is driven to sound an alarm, and the flip-flop 24 is reset.

On the other hand, after the one hour (3 minutes) of the timer has elapsed, if the timer operation is executed again using the one hour timer, the start key 5 for the chopsticks is operated once. As a result, the signal X8 of "1" is output and the timer signal 20 is output.
The timer is preset to one hour (3 minutes), the flip-flop 24 is set, and the AND gate 2 is opened again. Therefore, the subtraction operation of "-1 second" is started.

Further, when using the timer as a 100-minute counter, set the changeover switch to the rl OOJ side, and then set the knob 3B of the dial switch 3 to the desired position. At this time, a timer that is 10 times this set position is set for one hour. As mentioned above, when the 1" signal is shifted to the 5th bit of the shift register 10, the 1" signal is input to the 1st bit of the shift register 12, so that the decoder 17 uses it as a 100-minute timer. The decoding operation will be executed and one hour of the 100 minute timer will be output. The other operations are similar to those of the 10-minute timer.

[Second example] Next, a second embodiment will be described with reference to FIGS. 4 and 5.

This second example is an electronic watch equipped with an alarm function in addition to a timer function, and parts common to the first example are given the same numbers and their explanations will be omitted.

In FIG. 4, the timer dial switch 7 consists of a switch body 7A and a knob 7B. In this second embodiment, on the case body 1 around the switch body 7A, there are 11'', 12'', . . . as shown in the figure.
..., "12", "1", "2], ......, "1
2" scale is attached, and further scales are attached at equal intervals in the center between each scale. This allows 24-hour time data to be set in 30-minute increments and constitutes a 240-minute timer.

The mode switch 8 has switching positions rNJ, [TRJ, rAL
J, has a TMJ, and sets the normal clock mode (current time display on the display section 2), timer mode, alarm time setting mode, and time saint mode, respectively.

The correction key 9 is a key for correcting the alarm time setting mode 1; (here, the set time to the alarm counter and time counter, which will be described later, respectively) by -1 minute.

In this second embodiment as well, the knob 7 of the dial switch 7 once turned on does not change during operation of the timer.

Next, the circuit configuration of the main part will be explained with reference to FIG. The contact configuration of the dial switch 7 is the same as the first embodiment;
Book movable contact body 7C and seven solid contact bodies 7D, ~7D7
and are arranged concentrically. Thus, the fixed contact body 7D.

The numbers 11” to “48” are number 4 of dial switch 7.
It corresponds to 8 scales and outputs numerical data from rll to "48". That is, the shift register 30 with a capacity of 7 bits has the same function as the shift register 10, and each output of the 1st to 6th bits sequentially scans the fixed contact bodies 7D2-7D7 to take out serial data from the dial switch 7. . And this serial data shift register 31
(Capacity: ij, i6 bit) is input to the first bit, and then latched into latches 32 and 33 (both have a capacity of 7 bits). Shift register 31 and latches 32 and 33 have the same functions as shift register 12 and latches 13 and 14, respectively. Furthermore, the discrepancy detection section 15 outputs the discrepancy signal DA C to the signal generation circuit 35 or
is clock 96. , 962 is the force/mode signal 96T
Input R10AL10TM (all described later) and output signal I.
Dzl. In addition, it outputs signals 96 F, 1, F2, and 3.

The output of the latch 33 is input to a timer data decoder 34 having the same function as the decoder 17, where it is converted into the corresponding timer one hour, and preset into the timer counter 20 via the timer one hour storage section 1B. Further, the output of the latch 33 is inputted to a clock data decoder 36, converted to clock data, and sent to a clock counter 37 or an alarm counter 3.
8 is input. The counting outputs of the time counter 37 and alarm counter 38 are sent to the input terminal and input terminal B of the coincidence detection section 39, respectively, and are also sent to the current time or alarm time display section (shared) of the display section 2. will be displayed alternatively under the corresponding mode.

The coincidence detection section 39 is for detecting coincidence between the clocked time and the alarm time, and the coincidence signal 96 is sent from the coincidence detection section 39.

is input to the sound alarm unit 25, which drives the buzzer to generate an alarm sound. Further, the time counter 37 and the alarm counter 38 each receive a signal y41. Alternatively, the clock data from the clock data decoder 36 is taken in when /z/F2 is output. Furthermore, the flip-flop 24 is also set by the signal 〆F. Here, the signal zF1, 〆F2.9
6F.

are respectively timer mode, alarm time set mode,
The signal 96 under each mode of the clock agent set mode
They are output at the same timing as F.

As further illustrated, mode switch 8 is connected to clock 96.
A, and the switching position t1-TR
The respective outputs from J, "AL", and l'-T'MJ are input to the mode detecting section 40, where the mode setting is determined, and an erasure mode signal zTR1daAL1ρTM is output. In addition, the output of the correction key 9 is input to the one-shot circuit 41 and a signal "
However, the configuration of the correction switch 9 is the same as that of the start key 5, and the function of the one-shot circuit 41 is inputted as a one-shot mode signal 96TM or OAL or a gate control signal. In addition, +11 is sent to the time counter 37 via the OR gate 44 of the AND gate 42.
Input as a signal. Further, the output of the AND gate 43 is inputted to the alarm counter 38 as a +11 signal.

Furthermore, the second counter 45 is a sexagesimal counter, and its carry output, which outputs clock 0At - 1° minute interval, is sent to the time counter 3 as a +11 signal via an OR gate 37.
7.

Next (This operation will be explained. First, in the time set mode in which the current time is corrected, move the mode switch 8 to the switching position [T
Set it to MJ. As a result, the mode signal OTM is output from the mode detection section 40 and inputted to the signal generation circuit 35 and the AND gate 42.
．． It is output at the same timing as the signal yF and input to the time counter 37. Rotate the dial switch 7 to the desired time position. As a result, the time data decoder 36 outputs time data corresponding to the set position of the wheel switch 7, and the signal ρ1 is output.
．． The clock counter is set to 37 by the output. If the time you wish to set is not on the hour or in units of 30 minutes, operate the correction key 9. That is, each time the correction key 9 is operated, the one-shot circuit 41"
fmin is output, and the hour B1 counter 41 is incremented by +1 minute accordingly, allowing the time to be incremented by "+1 minute".

The time data at that time is displayed on the display section 2.

From this point on, move the mode switch 8 to position rNJ.
By setting , the current time is always counted by the +11 signal generated by the carry output of the second counter 45 to the time counter 37 .

On the other hand, setting the alarm time to the alarm counter 38+
The switching position rALJ, which precedes the S mode switch 8, is set. As a result, the mode signal DAAL is output from the mode detection section 40 and input to the signal generation path 35 and the AND gate 43. Further, a signal 9b is output from the signal generating circuit 35 at the same timing as the signal ρ, and is input to the alarm counter 38. Then, the alarm time is set in exactly the same way as the current time setting described above, and the alarm time corresponding to the reset position of the dial switch 7 is set in the alarm counter 38, and by operating the correction key 9, +1 minute” corrections can be made. The alarm time set in the alarm counter 38 is displayed on the display unit 2 only in the alarm mode instead of the current time.

After setting the alarm time in this manner, the mode switch 8 is switched to the switching position rNJ to maintain the normal watch mode. During this period, the coincidence detection section 39 always detects coincidence between the current time and the alarm time, and when the alarm time arrives, a coincidence clock 96oQ of "1" is outputted and input to the alarm section 25. , a buzzer will sound an alarm.

Furthermore, since the operation in the timer mode is almost the same as in the first embodiment, a detailed explanation thereof will be omitted, but first,
Set the timer mode by setting the mode switch 8 to the switching position TR. Then, the numerical data "1 to 481" corresponding to the set position of the dial switch 7, that is, 6-bit serial data indicating the set time of a 240-minute timer that can be set in 5-minute increments, is taken out and placed in the first bit of the shift register 31. is input to latch 32 .
33 to the timer data decoder 34 and to the mismatch detection section 15. And “B mismatch signal 9
After the appearance of 6c, the timer counter 20 is preset to the timer one hour value, and then performs a subtraction operation of 11 seconds.

Also, since the one-hour timer once set is held in the one-hour timer storage section 18, the same one-hour timer can be continuously set.
When the timer mode is used, the mode switch 8 is switched from another position to rTRJ again to set the timer mode. Then, the same one-hour timer as the previous time is set in the timer counter 2o again by the output of the signal DA, and the same timer operation is executed.

In the above embodiments, the timers are 10-minute, 100-minute, and 240-minute timers, but other timers may be used. Further, instead of using a dial switch, a slide switch may also be used.

〔Effect of the invention〕

As explained above, the present invention provides an electronic timepiece in which time data such as one hour on a timer and clock time can be set with a simple operation using a dial type or slide type switch. It is possible to provide an electronic timer, an electronic timer, and an electronic timepiece with ease of use not found in electronic timers equipped with a timer function and an alarm function.
