Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a timepiece that can display multiple types of time in conjunction with the switching operation of a switch.

[Prior Art] As a result of many years of living in a constant rhythm centered around a clock, we modern people tend to have our daily activities regulated by the time display on the clock. For example, if you have arranged to meet up with a friend, you will often advance your watch display by a predetermined amount of time and act in accordance with the advance time to complete the day's work well in advance of the agreed time. Even though we know that the clock's time display is advancing, it can be said that this is proof that our actions are controlled by the clock's time display itself.

[Problem that the invention aims to solve] By the way, when applying the above method of advancing the clock pointer at the time of taking the test, if the advance time is uniformly set regardless of the length of the test time,
Especially when the test time is short, the time until the end of the test becomes extremely short, which adds psychological pressure.
On the contrary, there are many problems such as increasing unnecessary tension.

Therefore, you can calculate a certain percentage of the test time, for example, about 10%, and advance the clock by that amount, but during the nervousness before the test, make sure to perform such operations accurately. This is extremely difficult, and there is a risk that the exact time itself will not be known due to an operational error.

As a result of continuing research into the above-mentioned problem as a person involved in cram school, the inventor of this invention has developed the above-mentioned method by making it possible to change the advance rate of the time display on the clock, rather than displaying the time display by sliding it by a certain amount of time. I found that the problem could be easily solved.

The present invention was developed based on the above knowledge, and uses a switch to switch the time display of a watch between a real time display state that corresponds to Japan Standard Time and an irregular time display state that differs from the current time display state. To provide a clock in which the rhythm of behavior can be easily changed by a simple operation without causing discomfort.

[Means for Solving the Problems] The clock according to the present invention, as schematically shown in FIGS. 1 and 2, has means for outputting a reference unit time signal _S2 corresponding to real time such as Japan Standard Time. , means for outputting an irregular unit time signal having a different unit time length from the reference unit time signal S ₂ , a switching means provided with an operation knob 7 a on the outer periphery of the main body case 2, and a means for outputting an irregular unit time signal having a different unit time length from the reference unit time signal S ₂ . The integrated real time is displayed, and the device is characterized by comprising means for displaying an irregular time obtained by integrating irregular unit time signals using the switching time as a starting point in conjunction with the switching operation of the switching means. .

[Operation] With the above configuration, in the normal use state, the time display means integrates the reference unit time signal to display the actual time in the same manner as a conventional watch, thereby informing the accurate current time.

If you want a different behavior pattern from normal, such as when taking an exam, turn on the operation knob 7a of the switching means provided on the outer periphery of the main body case 2, and the display means will change from the integrated display state of the reference unit time signal _S2 . , instead of the cumulative display state of the irregular unit time signal, the display state of the current time described above shifts continuously to the display state of the irregular time, and the time display continues without causing any discomfort to the operator. .

[Example] Hereinafter, based on the embodiment shown in Fig. 2 and Fig. 3, an example in which the present invention is applied to a wristwatch will be shown, but the present invention is not limited to this, and it can be used as a table clock, a wall clock, a stopwatch, or a clock exclusively used for examinations. Of course, it can be implemented with appropriate changes.

Note that the "reference unit time signal" used below is an example of a pulse with a pulse interval of 1 second or an integer fraction thereof, similar to conventional electronic watches.
"Real time display" refers to this "reference unit time signal"
By counting the number of pulses and displaying a display corresponding to the number of counts, if you match Japan Standard Time (JST) at a certain time, it will always match the time commonly used in Japan, almost the same as before. It means a time display.

On the other hand, an "irregular unit time signal" is a pulse train whose pulse interval is different from the "reference unit time signal", for example, 10% shorter, with a pulse interval of 0.9 seconds. By counting the number of pulses of the "unit time signal" and displaying the time in the same way as before, even if the time is set to match Japan Standard Time, there will be a discrepancy between the displayed value and the "actual time display." This also means a time display in which the value of this shift increases linearly.

As shown in FIG. 2, the watch 1 according to the present invention has the following features:
On the top side of the main body case 2, as "time display means", the pointer 4 of the analog display 3 and the liquid crystal display 6 of the digital display 5, which are almost the same as conventional ones, are provided, and from both sides of the main body case 2, Operation knobs 7a of changeover switches 7 and 8 that enable various manual settings such as display switching between "actual time" and "irregular time";
8a and a reuse 9 for manually moving the pointer 4 of the analog display 3 are exposed, and an electronic circuit 10 for displaying time on the displays 3 and 5 is housed inside the main body case 2.

In the electronic circuit 10, a clock signal _S1 consisting of a series of pulse trains at a sufficiently high pulse rate is formed in a clock signal generating section 12 using a crystal oscillator 11 as a driving source, and then the clock signal _S1 is sent to a unit time signal generating section. 13.

The unit time signal generation section 13 includes a first frequency dividing circuit 14 as a "reference unit time signal output means" and a first frequency dividing circuit 14 as an "abnormal unit time signal generation means".
A second frequency divider circuit 15 having a different frequency division ratio from the frequency divider circuit 14
The frequency dividing ratio of the second frequency dividing circuit 15 can be changed to a plurality of levels by switching the switch 8. In this embodiment, for real time display, the first frequency dividing circuit 14 forms a reference unit time signal _S2 with a pulse interval of exactly 1 second, and the second frequency dividing circuit 15 forms a reference unit time signal _S2 . It is possible to form irregular unit time signals S ₃ and S ₄ of 0.9 seconds and 0.8 seconds with pulse intervals shorter by 10% and 20%.

The reference unit time signal S ₂ is further input to the calculation unit 16, and is processed in substantially the same way as a conventional digital clock.
A series of pulse numbers in the reference unit time signal S ₂ are added to constantly form a digital signal S ₅ corresponding to the current time, and the digital signal S ₅ is sent via the first contact 20 of the switching section 17. Decoder 21
By sending the data to and decoding it, the real time can be digitally displayed on the digital display 5.

The present invention connects the unit time signal input to the analog display 3 with the switching operation of the switching section 17 provided as a "switching means" to convert the unit time signal S ₂ from the standard unit time signal S 2 to the irregular unit time signal S _{3 .} , it is characterized by being able to switch to the _S4 side.

The switching section 17 has the first contact point 20 described above.
In addition, the fixed end 23 of the contact 19 is connected to the step motor 22 of the analog display 3, and the two switching ends 24 and 25 are connected to the first and second frequency dividing circuits 14 and 15, respectively. The operation knob 7 that is connected to the output side of the main body case 2 and also extends from the main body case 2
The switch contact 19 is configured to switch from the solid line side to the dotted line side shown in FIG. 3 in conjunction with the ON operation of a.

The first contact 20 of the above-mentioned switching unit 17 also switches from the solid line side to the dotted line side in FIG. 3 in conjunction with the operation of the operation knob 7a, stopping the input to the digital display 5 and displaying it. stop.

The analog display 3 includes a step motor 22 and
It is equipped with a pointer 4 consisting of a long hand and a short hand that move in conjunction with the drive of the motor 22, and when a reference unit time signal _S2 is input, a time scale is formed so that the actual time is displayed in substantially the same way as in the past. has been
Therefore, when the above-mentioned irregular unit time signals S ₃ and S ₄ are input, an irregular time display state is entered in which the rotating speed of the hand 4 is higher than when the actual time is displayed.

Hereinafter, the operating procedure of the timepiece 1 according to the present invention will be explained in detail with reference to the explanatory diagram shown in FIG.

By initial adjustment, both the digital display 5 and the analog display 3 are set to Japan Standard Time, and as shown by the solid line, the time is displayed in accordance with the actual time like a conventional clock.

For example, if the test is started at time _t1 , by turning on the operation knob 7a at the same time, both the first and second contacts 20 and 19 of the switching section 17 are switched from the solid line side to the dotted line side. Instead, the display will display an irregular time. That is, the digital display 5 turns off the digital display state and notifies the operator that it has shifted to the irregular time display mode, and the unit time signal input to the step motor 22 of the analog display 3 has an actual pulse interval. The irregular unit time signal S ₃ is 10% shorter than when the time is displayed. Therefore, the hand advances 10% faster than when the actual time shown by the solid line is displayed as it is, and the irregular time shown by the dashed line is displayed. , are performed continuously starting from the real time display at time _t1 . For example, if actual time t ₂ is the end of the test, and the time between actual times t ₁ and t ₂ is 60 minutes, then at actual time t ₂ ', the 54th minute, which is 10% shorter, the pointer on the analog display The display indicates the test end time t ₂ ,
Further, at t ₂ ″, which exceeds the display t ₂ , the actual time t ₂ is reached.
Therefore, by preparing your answers with the aim of t ₂ in the irregular time display and reviewing your answers until t ₂ ″ in the irregular time display, which corresponds to t ₂ in the actual time, you can maintain psychological leeway. You can take the exam with the following information.

Note that when the operating knob 7a is pressed again at the display time t2 _' ', both the first and second contacts 19 and 20 of the switching section 17 return to their normal positions shown by solid lines, and the pointer 4 of the analog display 3 returns to normal. However, there is a predetermined advance time difference between the time and the actual time.Therefore, referring to the actual time display on the digital display 5 where the time display has been restarted, the hand position is returned to the position using the reset button 9. By making the correction, both the digital and analog displays 5 and 3 return to normal time display.

In addition, when displaying an irregular time, the unit time signal generator 1
The irregular unit time signals S ₃ and S ₄ that are applied from 3 to the analog display 3 via the switching section 17 are switched in conjunction with the ON operation of the operation knob 8a. That is, a triangular mark 26 is displayed on the liquid crystal display 6.
At the same time, the frequency dividing ratio of the second frequency dividing circuit 15 changes, and the irregular unit time signal changes from S ₃ to S ₄ .
Therefore, when the operation knob 7a is turned on in the same manner as described above at actual time _t3 in the state set to such a 20% increase fast-forwarding state, the advance rate is twice that of the 10% increase fast-forwarding, as shown by the two-dot chain line. This means that the time is displayed at an irregular time.

Note that the above configuration is an example, and instead of using the analog display 3 and the digital display 5 together,
It is also possible to switch the display using one set of digital displays. Further, instead of configuring a separate electronic circuit, a microprocessor may be provided as the control center, and the above operations may be performed by a program.

[Effects of the invention] As described above, the present invention includes, in addition to the conventional means for displaying the real time, a means for displaying an irregular time whose rate of advance is different from the real time. In conjunction with the switching operation of the switching means by turning on the operating knob 7a provided at an easily accessible position such as the outer periphery of 2, the irregular time is continuously displayed from the actual time display state starting from the switching point. This allows you to easily change the rhythm of your actions with simple operations and without any discomfort.

Furthermore, by making it possible to speed up the time rate in stages by 10%, you can avoid making mistakes when you want to demonstrate your maximum ability within a certain time frame, such as when taking an exam. It has many advantages, such as making it possible to allocate the best time to answer questions.
