Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-precision timepiece in which the accuracy can be adjusted in a complete state and the accuracy does not need to be readjusted even after the power supply is temporarily removed, and more particularly to a crown or other external input. The present invention relates to an inexpensive high-precision timepiece whose accuracy can be adjusted by operating means.

[0002]

2. Description of the Related Art At the present time, a high-precision timepiece that guarantees an accuracy of ± 10 seconds per year is sold together with a normal accuracy timepiece that guarantees an accuracy of ± 15 seconds per month. In high-precision timepieces, when assembling from the movement state to the complete state, it is necessary to adjust the precision in the complete state because the accuracy applied due to the pressure applied to the crystal unit and the floating capacitance that fluctuates between parts cannot be ignored. Was. Conventionally, as a clock that adjusts the accuracy in a complete state, a reference signal for a fixed time is input offline and compared with an internal signal to measure a deviation of the rate from the reference, and the rate variation data (rate of rate) is measured. Data for logic slowdown to correct the deviation)
A high-precision timepiece for adjusting the accuracy by storing data in an EEPROM or other writable nonvolatile memory.
There is a digital timepiece disclosed in Japanese Patent Application Publication No. 168187, which adjusts the accuracy by setting the rate-of-motion data by operating a button and storing the data in a volatile memory.

[0003]

In the former conventional technique, a receiving circuit must be added inside the watch, a new manufacturing facility for outputting a reference signal is required, and an EEPROM or other writable nonvolatile memory is required. Since the components are relatively expensive, there is a problem that the cost of the timepiece is increased. On the other hand, in the latter conventional technique, when the power supply is replaced, the set rate change data is lost, so it is necessary to readjust the rate, and a button and an LCD screen are required to input the rate change data. However, there is a problem that an analog clock without buttons or a liquid crystal screen cannot be applied to a high-precision clock.

The present invention has been made in view of the above, and it is possible to input the rate-of-change data in a complete state, so that the rate-of-change data does not disappear even when the power supply is replaced. The purpose is to provide.

[0005]

SUMMARY OF THE INVENTION In a high-precision timepiece according to the present invention, rate data can be input in a complete state without a receiving circuit or a button. You can now input.
In addition, this high-precision timepiece is writable and the data stored before the temporary removal of the power supply does not change even after the power supply is temporarily removed so that the data of the rate of change and other data do not disappear even when the power supply is replaced. Data storage means.

Here, when inputting the rate-of-rate data, it is possible to judge what operation was performed at what timing from the outside, and to confirm the displayed and stored rate-of-rate data for inputting the rate-of-rate data. The display to do so is now performed by the date wheel. Further, it can be performed by a second hand, minute hand or hour hand other than the date wheel. Further, the date wheel may be driven by another motor, or may be driven by the same motor using a swing mechanism.

Further, by storing two rate-adjustment data for coarse adjustment and fine-adjustment in separate means, even if the rate-adjustment data for fine adjustment has disappeared, the accuracy is not largely deviated. . Next, as a data storage means, a volatile memory and a power backup capacitor are used in place of an expensive writable nonvolatile memory to reduce the cost. Further, power consumption is suppressed by power supply extraction detecting means for detecting that the power supply has been extracted and oscillation control means for controlling the oscillation of the oscillation means to stop or restart.

Further, the data holding judgment means judges whether or not the data of the data storage means is held, and the judgment result is displayed on the display means. Here, when the oscillation control means determines that the power has been removed, first, the data storage means stores a plurality of duplicate data such as rate-of-change data. Next, when a new power supply is inserted and the operation of restarting the oscillation is performed, the data holding determination unit acquires the stored plurality of duplicated data and compares and determines them with each other. This determination result is displayed on the display means.

FIG. 3 is an explanatory diagram showing a method of an operation of switching to a mode of inputting second rate slowness data and an operation of inputting second rate slowness data. First, the operator pulls the crown to the second position (step S301), pushes the crown to the first position (step S302), waits 4 to 6 seconds (step S303), and moves the crown again to the second position. Pull (Step S30
By the operation of 4), the high-precision timepiece of the first embodiment switches to the mode of inputting the second rate slow / fast data.

Subsequently, the date indicator 204 is moved to the second

Here, the operation of switching to the mode of inputting the second rate slow / fast data involves the user accidentally performing the operation of switching to the mode of inputting the second rate slow / fast data, and changing the appropriate second rate slow / fast data. In order to prevent that
There is an ingenuity such as including an operation (step S302) that requires skill such as pushing the crown from the second stage to the first stage. FIG.
8 is a flowchart of a second rate slow / fast data input process of the data input control unit 107 according to the first embodiment. First, in step S401, the control enters the standby state from the crown condition detection unit 106 until there is a crown condition detection signal indicating that the crown is at the two-stage position. Proceed to S402. Step S402

In step S406, it is determined whether or not 6 seconds or more have elapsed from the start of the counting of the frequency-divided signal. If 6 seconds or more have elapsed since the start of the counting of the frequency-divided signal, the counting of the frequency-divided signal is terminated. Returning to S401, if 6 seconds or more have not elapsed since the start of the counting of the frequency-divided signal, the process returns to Step S405. If it is determined in step S405 that the crown is located at the second position, the process proceeds to step S407.

In step S407, it is determined whether or not the elapsed time is 4 seconds or more and less than 6 seconds from the start of the counting of the frequency-divided signal. If it is not the elapsed time, the counting of the divided signal is terminated, and the process returns to step S401. If the elapsed time is not less than 4 seconds and less than 6 seconds from the start of the counting of the divided signal, the counting of the divided signal is performed. Finished, data storage unit 1

Then, the date indicator 204 is moved to the position of the value of the second rate change data by controlling the second motor 206 via the display controller 103 (step S408), and the date indicator 204 is set to "
The frequency division signal is moved to the position "1" (step S409), the frequency-divided signal is counted for 2 seconds (step S410), and the process proceeds to step S411.

In step S411, it is determined whether or not the crown is at the position of step 0. If the crown is not at the position of step 0,
The date indicator 204 is moved to a position obtained by adding 1 to the value displayed on the date indicator 204 (step S412), and the process proceeds to step S413. In step S413, it is determined whether or not the date indicator 204 is displaying "17". If the date indicator 204 is not displaying "17", the process returns to step S410. In step S413, the date indicator 204 displays "17". If it is displayed, a return process to the normal mode is performed (step S414), and the process returns to step S401. In step S411, when the crown is at the position of step 0, the process proceeds to step S415.
