At time t2 when a predetermined time ta has elapsed in the timer t, the FETN is turned on and the connection point AG1 is turned on.
Are fixed to the low-potential-side power supply Vss, and the power generation coil 32 switches to a reception mode for receiving data received from the data transmission / reception device 100 (step SP2). And
At time t3, when a reception signal is sent from the data transmission / reception device 100 to the electronic timepiece 10 via the power generation coil 32, the power generation coil 32 receives the received data and the induced voltage is changed to the non-inverted voltage of the comparator 51, as described above.

At time t4, the comparator 51 compares the input induced voltage with the reference voltage 52, and determines whether correct received data has been received (step SP3).

If it is determined that the received data has been received, a detection signal corresponding to the received data is output to the data writing circuit 24, and the data writing circuit 24
Then, the received data is written into the data storage circuit 22 (step SP4). If data has already been written to the data storage circuit 22, the old data is deleted and the data is updated. At time t4 when step SP4 ends, FETN is turned off and FETn is turned off, thereby terminating the data reception mode (step SP5).

Next, from the falling time t4 when the FET N is turned off to the time t5, the mode is switched to the data transmission mode (step SP6), and the operation of turning on and off the FETP and the FETN is repeated to repeat the operation. The transmission data stored in the storage 22 is automatically transmitted.

In this data transmission mode, transmission data is read out from the data storage circuit 22, and the FETP and FETN of the rectifier circuit 33 are simultaneously turned on and off based on this data, so that FETP → the power generation coil 32 →

[1.4] Effects of the First Embodiment As described above, according to the present embodiment, the electronic timepiece 10 is mounted on the data transmission / reception device 100 and the operation input means 16 is operated to give an instruction. When there is an input, the received data transmitted from the data transmission / reception device 100 is stored in the data storage circuit 22 of the analog electronic timepiece 10 via the power generation coil 32. Thereafter, the transmission data stored in the data storage circuit 22 is transmitted to the data transmitting / receiving device 1 via the power generation coil 32.
Send to 00. As described above, by transmitting and receiving data using the power generation coil 32, a time recovery circuit and the like built in the conventional timepiece can be omitted, and data transmission and reception can be realized with a simple configuration. Moreover, it is not necessary to newly add an antenna or the like for data transmission, and the present embodiment can be realized by the configuration of the electronic timepiece 10.

Here, when the data received from the data transmitting / receiving device 100 in the data storage circuit 22 is, for example, logic slow / fast data of the frequency dividing circuit 13 for dividing the reference oscillation signal from the oscillation circuit 12, The oscillation circuit 12 can be adjusted based on the data. In addition, the electronic timepiece 10
If the data transmitted from is used as the identification number (hereinafter referred to as ID number) data of the timepiece 10, the data transmission / reception device 100 allocates the data to the timepiece 10 without disassembling the timepiece 10. The ID number can be easily identified from the outside, and the product can be easily managed at the distribution stage and whether or not it is fake can be easily determined. Note that the transmission data may be information for notifying the self-operation state of the electronic timepiece 10.

In the first embodiment, the power generation coil 32 is used for data transmission and reception.
Numeral 2 has a larger number of turns and a thicker winding than the driving motor coil provided in the display device 14. For this reason, since the inductance of the power generation coil 32 is larger than that of the motor coil, the communication quality at the time of transmission and reception can be improved, and the S / N can be improved. Furthermore, when the power generation coil 32 is in a non-charging state, data transmission and reception are performed using the power generation coil 32. Therefore, data transmission and reception can be accurately performed in distinction from a magnetic field generated in the power generation coil 32 during charging. It can be carried out.

When data is being transmitted and received, a special display is performed on the display device 14 in order to inform the user of this. That is, in the case of an analog timepiece, irregular hand movement (hand movement every two seconds) is displayed, and in the case of a digital timepiece, the fact that data is being transmitted / received is displayed on the display panel. This is because data transmission / reception may not be performed correctly during power generation, and it is therefore desirable to display that data transmission / reception is in progress and prevent the user from shaking the electronic clock to generate power. Further, the comparator 51 forming the detection circuit 23 has a voltage input terminal and a low potential side power supply Vss.
, The application of voltage to the comparator 51 is prohibited except in the reception mode. Thus, power consumption can be reduced.

[2] Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the analog electronic timepiece 60 is configured to only receive data from the outside. In data transmission, FETP and FE
Since the TN transistor is turned on at the same time to allow current to flow, in a state where power generation is performed in a normal portable mode, charging of the large-capacity capacitor 34 is hindered and charging efficiency may be reduced. Therefore, an input by an external operation (operation input means 16) is required. However, when only data reception is performed, the external operation input means 16 is not required, and the mode may be automatically switched to the data reception state every predetermined time ta. This electronic timepiece 60 has a FETN only at both ends of a diode D3.
In the operation of the electronic timepiece 60, data reception can be realized by executing steps SP1 to SP5 in FIG.

[3] Third Embodiment Next, a third embodiment of the present invention will be described with reference to FIG. In the third embodiment, the configuration of the electronic timepiece is the first
Since this embodiment is the same as the embodiment, description will be made with reference to FIGS. In the third embodiment, a drive control signal (motor pulse) output from the control circuit 15 to a pulse motor for driving a pointer provided on the display device 14 is provided.

In the following description, the output cycle of the motor pulse is assumed to be time Ta. At time t11, when the motor pulse goes to the “H” level and at time t12 again goes to the “L” level, the control circuit 15 sets the time t12
At time t13 when a predetermined time Tb has elapsed since FE, FE
Tn and FETN are turned on to shift to the data reception mode. However, during the period from time t13 to time t14, no data is transmitted from the data transmitting / receiving device 100, which is the external device, so that at time t14, the FETn and the FETN are turned off and the normal mode is set again.

Thereafter, at time t15, when the motor pulse goes to the "H" level, and at time t16 again goes to the "L" level, the control circuit 15 sets the FET at time t17 when a predetermined time Tb has elapsed from time t16.
n and FETN are turned on, and the mode shifts to the data reception mode. Then, at time t17, when a reception signal is sent from the data transmitting / receiving device 100 to the electronic timepiece 10 via the power generation coil 32, the power generation coil 32 receives the received data, and the induced voltage is output to the non-inverting input terminal of the comparator 51. You. At time t18, the comparator 51 compares the input induced voltage with the reference voltage 52, determines whether correct received data has been received, and determines that the received data has been received. Is detected by the data writing circuit 24.
The data write circuit 24 writes the received data into the data storage circuit 22.
Further, at time t18, FETN and FETn
Is turned off to end the data reception mode. Thereafter, at time t19, when the motor pulse goes to the “H” level and again at time t20 to the “L” level, the control circuit 15 switches to the data transmission mode at time t21 when a predetermined time Tc has elapsed from time t20, By repeating the operation of turning on and off the FETP and FETN, the transmission data stored in the data storage circuit 22 is automatically transmitted.
As described above, in the third embodiment, the first
In addition to the effects of the embodiment, at the timing not affected by the motor pulse, the mode can be automatically shifted to the data reception mode or the data transmission mode, and more reliable data transmission / reception can be performed.

[4] Fourth Embodiment Each of the above embodiments is a case in which strict data transmission / reception is performed, but is an embodiment in which data is simply input. In data input, not only data in which one data such as numerical data or character data becomes a plurality of bits, but also simple data input such as Yes / No input exists. The fourth embodiment is an embodiment when such simple data input is performed. Book 4
In the embodiment, instead of using an external magnetic field for data input as in the above embodiments, the rotating weight 44 (see FIG. 3)
Is rotated by shaking the wristwatch to generate an electromotive voltage in the power generation coil. When the number of times the power generation voltage exceeds the predetermined level within a predetermined time is equal to or greater than a predetermined number, a certain value (“1 "Or" 0 "or" Ye
s "or" No "). More specifically, as shown in FIG. 9, the power generation voltage is changed from time t31 to time t32 when a predetermined time Td elapses. When the number of times exceeding the predetermined detection level exceeds a predetermined number (for example, two times), it is determined that the input data of the user is “1” or “Yes”. Since the number of times that the generated voltage exceeds the predetermined detection level from the time t31 to the time t32 when the predetermined time Td elapses is three times, and exceeds the predetermined number of times, Thus, the input data of the user is determined to be “1” or “Yes.” As described above, according to the fourth embodiment, simple data can be obtained without changing the configuration of the electronic timepiece.
