And the output terminal of the transmission circuit 13 and the antenna 14 are connected.

An electrocardiogram detection circuit 11 detects and amplifies an electrocardiogram signal detected by the electrode 10, and outputs a detection signal Sk which is a pulse signal synchronized with the electrocardiogram signal. The heart rate data encoding circuit 12 counts the period of the detection signal Sk by using the reference signal as an Sd signal, converts the Sd signal into serial data, and outputs a serial data encoded signal Sr. The transmission circuit 13 modulates the coded signal Sr and transmits the coded signal Sr from the antenna 14 as a radio signal. For example, when the heart rate is 80, the cycle of the detection signal Sk is 750 ms,
If a 600 Hz signal is used as the reference signal, the Sd signal becomes 450. This Sd signal is converted into a serial data code signal Sr, modulated by the transmission circuit 13, and transmitted from the antenna 14.

And T4, the output terminal of the switch means 33 and the input terminal of the display drive circuit 23 are connected, and the output terminal of the display drive circuit 23 and the input terminal of the display means 24 are connected. A first output terminal of the comparison circuit 25 is connected to a first input terminal of the pitch data generation circuit 26, and a second output terminal of the comparison circuit 25 is connected to a second input terminal of the pitch data generation circuit 26 Then, the output terminal of the pitch data generating circuit 26 and the input terminal of the sounding means 27 are connected.

As described above, for example, when the heart rate is 80, the Sd signal is 4
Since it is 50, so that the heart rate per minute is 80,
The data is converted to 36000/450 and the heart rate data decoding circuit outputs a heart rate of 80.

When the electronic timepiece with a pacemaker is worn on the left arm, the user wears it without operating the external operation means 31. Before starting the exercise such as jogging, the wearer of the electronic watch with a pacemaker operates the external setting means 28 to set his / her target heart rate in the setting circuit 29 and stores the target heart rate in the target heart rate storage circuit 30. Remember. The target heart rate output from the target heart rate storage circuit 30 as the information generating means and the heart rate output from the heart rate data decoding circuit 22 are determined by the switch means
Input terminal. Under normal conditions, the switches S1 and S2 of the two switches of the switch means 33 are connected to the terminals T3 and T4, and the heart rate and the target heart rate are determined from the switch S1 of the input terminal of the switch means 33 to the terminal T3 and the terminal T4.

In FIG. 3, the target heart rate 44 and the heart rate 43 are displayed on the display section 42. For example, a jogging mode and a clock mode are set. In the jogging mode, the target heart rate and the heart rate are displayed. It is also possible to display the current time and the like generated from a timing circuit (not shown) in the clock mode.

In the case of healthy sports, the target heart rate is generally an anaerobic work area, which is a point at which aerobic exercise shifts to anaerobic exercise, so-called AT (Anaerob).
icThreshold) is the maximum heart rate (MaximumHea) in a high exercise intensity state where exercise cannot be continued due to lactic acid in the blood.
It is said that from 60 to 85% of rt Rate (HRmax) is suitable. The heart rate from 60 to 85% of the HRmax is a heart rate which is also called a health promotion zone. By repeatedly training at this level of exercise intensity, the AT level is improved, and the user can feel comfortable even at the same heart rate. It is said to be.

ng heart rate training-its theory and practice)

The first input terminal of the comparison circuit 25 receives the target heart rate which is the output of the target heart rate storage circuit 30, and the second input terminal receives the heart rate which is the output of the heart rate data decoding circuit 22. 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 up signal Sup is output to the first output terminal, and the actual heart rate is output. 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 first input terminal of the pitch data generation circuit 26 or the second output terminal. . Pitch data generating circuit 2 receiving up signal Sup
6 is to gradually raise the pitch of the generated pitch signal, and the sounding means 27 generates a pitch sound to notify the wearer of the increased pitch signal, and the wearer raises the running pitch. When the actual heart rate rises and falls within the target heart rate range, 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 as soon as the wearer enters the range of the target heart rate. In FIG. 3, the target heart rate 44 of the display unit 42 is set to 160-170, and the actual heart rate 43 is 162. Therefore, since the actual heart rate falls within the range of the target heart rate, The pitch signal generated by the pitch data generation circuit 26 has a constant pitch.

When the electronic timepiece with a pacemaker is mounted on the right arm, as shown in FIG. 4, the electronic timepiece is mounted upside down, and the external operation means 31 is operated to operate the two switches S1 and S2 of the switch means 33. Connected to terminals T1 and T2. The heart rate and the target heart rate are input from the switch S1 of the input terminal of the switch means 33 to the input terminal of the display rotation means 32 through the terminal T1, and the display of the display section 42 of the display means 24 is rotated by 180 degrees by the display rotation means 32. The output is converted into data to be rotated, passes through the terminal T2 of the switch means 33, is input from the output terminal of the switch S2 to the input terminal of the display drive circuit 23, and is displayed on the display section 42 of the display means 24. . Thus, even if the electronic timepiece with a pacemaker is mounted upside down as shown in FIG. 4, the display section 31 can display a normal display as in FIG.

[0019]

According to the present invention, even when the electronic timepiece is mounted upside down on the right arm, the external operating means 31 is operated to operate the display rotating means 32, thereby displaying the display means 24.
Can be rotated by 180 degrees, so that the display can be performed normally.

In the embodiment of the present invention, the information generated by the information generating means is a heart rate, which is heart rate information, and a target heart rate. However, the present invention is not particularly limited to this, and time information or other information may be used. Of course.
