The "M" register is a mode switching register and is "0".
Alternatively, "1" is sequentially switched and stored. When "0", the normal mode is set, and when "1", the recall mode is set. On the other hand, the “F” register is for selecting the measurement mode. When it is “0”, the measurement data is not displayed by the sensor element 31, and when it is “1”, the measurement data is displayed by the sensor element.

FIG. 7 shows a flowchart of the operation performed by the control unit 20 of the wristwatch 1 based on the above conditions. In step S1, it is determined whether or not there is a key input, and if there is no key input, the time is displayed on the timekeeping circuit 22 on the display unit 4 (step S2), and then the content of the "F" register is determined ( Step S3). And
When the "F" register is "1", the sensor information detected by the sensor element 31 and received through the antenna 6a is displayed on the display unit 4 and is sent to the storage unit 52 of the external storage unit 50 for storage. (Step S4). on the other hand,
If there is a key input in step S1, it is determined whether or not it is the key input of the push button switch 5a (step S5), and then the numerical value of the "M" register is determined (step S6). When the "M" register is "0",
Invert the value in the "F" register (step S7),
When the value is "1", the sensor information stored in the storage unit 52 of the external storage unit 50 is sequentially read, and the contents are sequentially displayed on the display unit 4 (step S8). Therefore, in addition to displaying the sensor information detected by the sensor element 31, it is possible to display the sensor information stored in the storage unit 52. The display of the received sensor information is stopped when the sensor information stored in the storage unit 52 is read when the "F" register is "1". Then, in step S5, if it is not the key input of the push button switch 5a, the operation shifts to the key input operation of the other push button switches, and the processing corresponding to the key input of the switch is performed (step S9).

In this embodiment as described above, the transmitter 30 for detecting and transmitting the sensor information, the wristwatch 1 for receiving and displaying the sensor information, and the external memory for detachably attached to the wristwatch 1 to store the sensor information. Since it is configured by the means 50, by mounting only the transmitter 30 on a predetermined body part, the sensor information can be detected and displayed even when the user is exercising or working. Further, since the sensor information is stored in the external storage means 50, it is possible to store a large amount of capacity, and it is possible to change or expand the information, and
The inconvenience of erasing sensor information is eliminated. Further, in the present embodiment, since the program for displaying the stored sensor information is stored in the external storage means 50, not only the new sensor information detected but also the already stored sensor information can be displayed. It is convenient to use.

Note that the transmission and reception of the sensor information in the above embodiment may be wireless or wired, and may be performed by optical means such as electromagnetic induction or infrared rays, and as sensor information detected by the sensor element, Heart wave, blood pressure,
It can be applied to body temperature, skin resistance, and other biological information.
