The Sd signal is converted to a serial data Sr signal, modulated by the transmission circuit 13, and transmitted from the antenna 14.

FIG. 2 shows an embodiment of the receiving section 2 of the electronic timepiece with a running pacemaker according to the present invention. The receiving section 2 includes a receiving circuit 21, a heart rate data code circuit 22, a display driving circuit 23, a display means 24, a comparing circuit 25, a pitch data generating circuit 26, a sound generating means 27, an external operating means 28 , A setting circuit 29, and a target heart rate storage circuit 30. The receiving circuit 21 of the transmitting section 1 and the receiving section 2 and the heart rate data decoding circuit 22 constitute a heart rate detecting means. The antenna 20 is connected to the input terminal of the receiving circuit 21, the output terminal of the receiving circuit 21 is connected to the input terminal of the heart rate data decoding circuit 22, and the output terminal of the heart rate data decoding circuit 22 is connected to the display driving circuit 23. The first input terminal and the first input terminal of the comparison circuit 25 are connected. The external operating means 28 is connected to the input terminal of the setting circuit 29, the output terminal of the setting circuit 29 is connected to the input terminal of the target heart rate storage circuit 30, and the output terminal of the target heart rate storage circuit 30 is connected to the display drive circuit. 23, the second input terminal of the comparison circuit is connected to the second input terminal of the comparison circuit, the output terminal of the display drive circuit 23 is connected to the input terminal of the display means 24, and the first output terminal of the comparison circuit 25 is A first input terminal of the pitch data generation circuit 26 is connected, a second output terminal of the comparison circuit 25 is connected to a second input terminal of the pitch data generation circuit 26, and an output terminal of the pitch data generation circuit 26 is connected. And the input terminal of the sounding means 27 are connected.

The receiving circuit 21 amplifies, detects, and demodulates the radio signal from the transmitting unit 1 received from the antenna 20, and outputs a received signal Sj. The received signal Sj is the same as the coded signal Sr of the transmitting unit 1 described above. The heart rate data decoding circuit 22 decodes the reception signal Sj and detects the detection signal Sk.
Is counted as a Sd signal by using the reference signal as a reference signal, and converted into a one-minute heart rate, and the heart rate is output.
As described above, for example, when the heart rate is 80, the Sd signal is 450, so the conversion of 36000/450 is performed so that the heart rate per minute becomes 80, and the heart rate data decoding circuit 22 A heart rate 80 is output.

The heart rate output from the heart rate data decode circuit 22 is input to a first input terminal of a display drive circuit 23, passes through the display drive circuit 23, and the display unit 31 as shown in FIG. Is displayed as the heart rate 32. The wearer of the electronic timepiece with a running pacemaker operates the external operation means 28 to set his / her target heart rate in the setting circuit 29 in the setting circuit 29 and to set the target heart rate storage circuit 30

[0013] In the case of healthy sports, the target heart rate is generally an anaerobic work range value, which is a point at which aerobic exercise shifts to anaerobic exercise, so-called AT (Anaero).
HR), which is a heart rate at which the exercise intensity up to the ic threshold level is reached, and the maximum heart rate (MaximumH) at a high exercise intensity state where exercise cannot be continued due to lactic acid in the blood.
It is said that a range of 60 to 85% of "ear rate (HRmax)" is suitable. This HRmax 60
The heart rate from 1 to 85% is a heart rate also referred to as a health promotion zone, and it is said that by repeatedly training at this level of exercise intensity, the AT level is improved, and the same heart rate can be easily felt. (Reference: Tateto Sotooka, Heart Rate Train
ing, heart rate training—theory and practice) The first input terminal of the comparison circuit 25 has the actual heart rate output from the heart rate data decoding circuit 22 and the second input terminal has the output of the target heart rate storage circuit 30. The comparison circuit 25 compares whether or not the actual heart rate is within the target range of the target heart rate. If the actual heart rate is lower than the target heart rate, the comparing circuit 25 outputs the up signal Sup to the first. If the actual heart rate is higher than the target heart rate, the down signal Sdn is output to the second output terminal, and the up signal Sup or
The down signal Sdn is input to the second input terminal. The pitch data generating circuit 26 receiving the up signal Sup signal
The pitch of the generated pitch signal is gradually increased, and the raised pitch signal is reported to the wearer by the sounding means 27 generating a pitch sound, and the wearer raises the actual running pitch by increasing the running pitch. When the heart rate rises and falls within the range of the target heart rate, the pitch of the pitch signal is kept constant. Upon receiving the down signal Sdn, the pitch data generating circuit 26 gradually reduces the pitch of the generated pitch signal, and the sounding means 27 generates a pitch sound to notify the wearer of the lowered pitch signal. When the wearer lowers the running pitch, the heart rate is actually lowered, and the pitch of the pitch signal is kept constant when the heart rate falls within the range of the target heart rate. In FIG. 3, the target heart rate 33 of the display unit 31 is set to 160-170, and the actual heart rate 32 is 162. Therefore, since the actual heart rate is within the range of the target heart rate, The pitch signal generated by the pitch data generation circuit 26 has a constant pitch.

[0014]

The heart rate of the health promotion zone suitable for enhancing the physical strength is set as the target heart rate by the setting circuit 29 and stored in the target heart rate storage circuit 30, and the actual heart rate obtained from the transmission unit 1 is obtained. When the actual heart rate is lower than the target heart rate, the pitch of the pitch signal is increased. When the actual heart rate is higher than the target heart rate, the pitch signal pitch is increased. By lowering and notifying the wearer, the wearer can know during traveling whether the actual heart rate is higher or lower than the range of the target heart rate. Further, the actual heart rate can be automatically brought into the range of the target heart rate only by running the running pitch in accordance with the pitch signal.
