Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the construction of an all-electronic timepiece that has a sounding means and displays the time using an electro-optical display means, and more specifically relates to an improvement in the method of adjusting the timepiece. It is.

In recent years, the development of digital electronic watches has been remarkable, and in the early days,
Watches have progressed from simple ones that display the minutes, to watches with complex display functions, to watches with complicated additional functions.

However, the time adjustment method has also become a problem.

Compared to conventional analog clocks, they are more complex and require delicate timing, which is especially noticeable in clocks with additional functions, and this is becoming a major barrier to their widespread use.

Additional functions with high practical value are the alarm alarm and stopwatch functions, and the alarm function in particular has a wide range of applications and is integrated into daily life.

The present invention realizes a method for easily making corrections to the above-mentioned specification clock, and provides an electronic clock with an easy-to-operate alarm function.

FIG. 1 shows an overview of a system using an electronic timepiece according to the present invention.

Reference numeral 2 denotes a highly accurate external standard timepiece, and by setting the electronic watch 1 of the wearer as shown by the arrow, the standard time is sensed through the sounding means 4, which is a receiving means, and the time is instantaneously adjusted.

The sound generating means 4 is normally used as a time signal by emitting an alarm at an arbitrary time to wake up the user.

It is also conceivable to carry out the communication through the telephone line 3 as an even wider system.

The user dials a service station and performs a series of operations to obtain a standard time signal and automatically adjust the time.

At this time, the transmission method for transmitting information from the external standard clock 3 to the sound generating means 4 may be sound waves, magnetism, radio waves, etc.

If the sound generating means 4 has a coil, a low frequency magnetic pulse can be applied, and when radio waves are used, a tone burst waveform in which a high frequency is added to a low frequency pulse is used.

It is also conceivable to use sound waves when transmitting information from the telephone line 3 to the sound generating means 4.

Furthermore, in order to increase the reception sensitivity of the receiver, making the sound generating means 4 removable from the watch body is also one means for correcting the time in an optimal state.

FIG. 2 is an internal block diagram of the electronic timepiece 1 having reception and sound generation functions.

5 is a sound generating means having a reception function, and 6 is a preamplifier and waveform shaping circuit.

7 is a register for storing information, 8 is an internal clock generation circuit for operating the register 7, and 9 is a correction control section which includes operating members from outside the watch body.

Numeral 10 is a crystal oscillator, 11 is an oscillation frequency dividing circuit, and 12 is a counter necessary for time display, which has a preset mechanism and has a set time memory, coincidence detection, and sound generation means driving circuit.

13 is a decoder, and 14 is a display section.

In other words, only functions 10 to 14 work in the normal carrying state, and the other functions that work only during correction are stopped by the correction control section 9.

Functions 5 to 9 operate during correction, and even if a somewhat large amount of power is consumed, the correction is carried out in a very short time, so there is no problem.

Figure 3, A is the standard time transmission pulse from the transmitter, B
is the clock pulse of the internal clock generator circuit 8 in FIG.

The first pulse a of A is a forced synchronization pulse for synchronizing the internal clock B so that the information group b of the transmitted pulses can be input to the register 7 by the internal clock B of the electronic clock being corrected.

That is, when a is received, a predetermined number of clock pulses B are generated after a certain period of time.

The final information of information group b, such as the BCD code, is now packed into the register I in FIG. 2, and the correction is completed by replacing it with the contents of the preset counter 12 in FIG.

In the present invention, when a large amount of information is being sent or the transmission speed is slow due to unavoidable reasons, when a large amount of transmission time is required, it is sufficient to transmit an advanced time assuming that the time information has been transmitted. The problem can also be solved by manipulating the order of information transmission.

When electronic watches become widespread, the present invention makes it possible to efficiently correct a large number of electronic watches using a small number of transmitting devices.

The transmitting device can be used as a clock in general offices, department stores, etc., and the transmitting device itself can be directly connected to a central device via a communication line such as a telephone line for accurate management.

Further, according to the present invention, since the sounding means becomes the receiving means, it is possible to provide a highly practical electronic timepiece having a simple adjustment method without increasing the number of parts or increasing the cost.

Therefore, the practical effects of the present invention are very large.

Further, it is also possible to use the sounding means as a receiving means for receiving a rate speed/acceleration command signal.

Furthermore, although the present invention has been described with respect to an example with a time display section, it is also effective in cases where the sounding means displays the time, for example, when making a sound time signal using Morse code.
