Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to a wall-mounted clock, etc., which is equipped with a device for receiving signals such as light inside, and has a function of reading signals from the outside and correcting the time. This one is about large watches.

[Prior Art] Conventionally, the time of table clocks and wall clocks is manually adjusted.

[Problem 1 to be solved by the invention] In the conventional example, the time is manually adjusted, so the range is limited because the watch can only be placed within arm's reach.Also, in large watches, the weight is large. Because of this, it is difficult to take the watch in and out to adjust the time.Therefore, you have no choice but to leave the watch with the wrong time.

The present invention aims to eliminate such drawbacks, and by providing a watch with a built-in device that can easily adjust the time, or the device of the present invention that can be incorporated into an existing watch, even medium-sized and large-sized watches can be used at all times. The purpose is to make it possible to know the exact time.

[Means for Solving the Problems] A timepiece with a remote control device for time correction of the present invention includes a device for receiving signals such as light, a circuit for determining a signal code, and a reference signal for timekeeping inside the timepiece. The present invention includes a transmitting section for generating signals for normal driving, a drive pulse shaping circuit for shaping signals for normal driving and signals for time adjustment, and a motor section for moving the hands.

Also, the transmitter that transmits the time adjustment signal must be separate from the watch body.

The method for adjusting the time is to send a signal that is an integral multiple of the normal signal to advance the time, and to reset the drive signal either from the beginning or midway and to stop the hand movement if the time is to be delayed. Features.

The clock motor 15 includes a drive pulse shaping circuit 14 that shapes a drive signal for driving the clock motor.

In the case of time adjustment, signal control is performed using the block indicated by the broken line 16, and a signal for time adjustment is sent to the clock motor 15 to perform time adjustment.

The configuration consists of a receiving section 1 that receives signals sent from a transmitter.

α2 is a received signal input terminal, l@21.22 is a code input terminal, which has a code check circuit that compares the transmitter code and the code set at this terminal and accepts the input if the code is the same. are doing. Note that 23 is a timing transmission terminal which generates a 38 KHz signal by ORing. Nl19 and 10 are independent cyclic signal output terminals whose outputs are inverted every time a received signal is input.

In normal driving, pin N of the code bit determination circuit 27
An H signal is output from α9 and an L signal is output from pin Na10 to turn on the analog switch 232, turn off 231, and send the Q+a signal to the data shift circuit 264 via the OR gate 233.

When fast forwarding by time adjustment, the transmitter sends a 12-bit signal to control the cyclic signal. Light is received by the light receiving element 25, and judged by the code bit judgment circuit 27 via the Tr 26. If OK, output the L signal from the pin N [L9, turn off the analog switch 232, turn on 231, and OR gate the Qlo signal. 253 to the data shift circuit 234. Thereafter, the method up to the pointer movement is as described above.

Pin Nl110 and oscillation circuit 212 frequency divider circuit 22. A reset terminal of the drive pulse shaping circuit 23 is connected, and normally an L signal is output, but when an H signal is output, each part is reset and no motor drive pulse is output. Therefore, the movement of the hands stops. The movement of the hands is stopped only while the H signal is being output, and all that is required is to send it again at the regular time and return to the L signal.

The above is a description of the reception relationship, but as for the transmitter, for example, a transmitter using Toshiba TO9148 is commercially available, so it may be used as is.

[Effects of the invention] As described above, the invention is to adjust the time of a clock using signals such as light, but according to the invention, the time can be adjusted easily and remotely using a transmitting/receiving device. Especially for medium-sized and large-sized watches, you are freed from the task of removing the clock from the wall etc. to adjust the time, and you do not have to make a big decision to remove the clock once a year, but only about once a month. You can easily adjust the time using the button, and the effect is extremely large.

For watches that are highly public, it would have a great impact on users if they could always tell the accurate time, and the present invention, which allows for easy time adjustment, has a great effect. Further, the transmitter/receiver section of the present invention can be retrofitted to an existing watch, making the present invention extremely versatile.
