A wristwatch comprises an ID Tag (data carrier) function applied to an RF-ID system. A watch main body comprises a reinforce resin-based case having band attachments to which wrist bands are engaged, and a resin-based bezel cover covering the upper section and outer periphery of the case. The case incorporates a display member composed of a fixing member, a resin-based display frame member, a hard glass member, and a waterproof packing, and a circuit member composed of a synthetic rubber-based module cover member, a module fixing member, a module and a module cover member. The case is sealed with a bottom cap member formed of a magnetic material via a waterproof packing, and is further covered with a resin-based case cover. A module comprises module housing members, a watch LSI substrate, a data carrier IC substrate having a data carrier IC that incorporates a control circuit for encoding/decoding and authenticating a transmitting/receiving signal and a data memory storing ID, and a data carrier antenna coil connected to the data carrier IC substrate and assembled at the outer periphery of the watch LSI substrate.

A control unit of a measuring apparatus controls a sound driving circuit to make a sounding unit generate pitch sounds at a predetermined pace for three minutes. After generation of the pitch sounds for three minutes, a heart rate sensor measures a heart rate of an exerciser who has executed an exercise in synchronism with the generated pitch sounds, and the measured heart rate is stored in RAM. Further, the control unit controls the sounding unit to generate pitch sounds at a different pace for another three minutes, and a heart rate of the exerciser is measured and stored similarly. Based on the measured heart rates and personal data such as an age of the exerciser input through a key input unit, a level of objective physical strength of the exerciser is calculated and displayed on a display device. In other words, physical strength of the exerciser is objectively evaluated based on physical data such as a heart rate that varies when the exerciser performs the exercise.

A pulse counting apparatus which has a simple structure and makes few count errors. When the number of pulses at a wrist or the neck of the user counted by means of palpation amounts to 10 and the user stops by using an S1 key the measurement of the pulse counting time period in a timer, it is determined whether the pulse counting time period is 3 seconds or less. If the time period is 3 seconds or less, it is determined that the pulse is miscounted, the value of the timer is cleared and '1' is set in a flag. As a result, the apparatus is switched to a measurement mode. If the time period exceeds 3 seconds, pulses per minute are calculated from the time period and the number of the pulses 10. An exercise intensity corresponding to the pulse is calculated from the pulse and the set age of the user. The pulse and the exercise intensity is displayed in a display.

An exercise level of difficulty data output apparatus outputs exercise level of difficulty of an exercise which a user takes, as exercise level of difficulty data, which can be used for general purposes in the exercise physiology. Using the apparatus, the user can objectively learn the exercise level of difficulty of his (or her) exercise for keeping himself healthy or for developing his physical strength. The exercise level of difficulty data output apparatus calculates exercise level of difficulty data from counted pulse number of the user and his age, and outputs the exercise level of difficulty data. Further, the exercise level of difficulty data output apparatus calculates and displays a predetermined pulse-number range indicating the most suitable exercise level of difficulty for the age of the user.

An exercise-level of difficulty data output apparatus outputs exercise-level of difficulty of an exercise which a user takes, as exercise-level of difficulty data, which can be used for general purposes in the exercise physiology. Using the apparatus, the user can objectively learn the exercise level of difficulty of his (or her) exercise for keeping himself healthy or for developing his physical strength. The exercise-level of difficulty data output apparatus calculates exercise-level of difficulty data from counted pulse number of the user and his age, and outputs the exercise-level of difficulty data. Further, the exercise-level of difficulty data output apparatus calculates and displays a predetermined pulse-number range indicating the most suitable exercise level of difficulty for the age of the user.

A device is used for precisely measuring an electrocardiographic wave and sphygmus. The device displays a number of sphygmus or the highest and lowest blood pressure on the basis of measured data. In the device, it is judged if an electrocardiographic wave signal generated from an electrocardiographic wave detecting circuit and the sphygmus signal generated from a sphygmus detecting circuit have been output in a corresponding manner to each other. If not, or if one of the above signals has not been detected, either the gain of the electrocardiographic wave detecting circuit or the gain of the sphygmus detecting circuit is increased so as to allow a precise detection of the signal.

A time calculating device calculates a time which a user of the device requires to run a distance such as a whole distance of a marathon race. The time calculating device is provided with a pulse frequency memory which measures pulse frequencies of the user when the user runs a given distance at least twice at predetermined different paces, and which stores the measured pulse frequencies. The time calculating device is further provided with an age input key for inputting age data of the user, and a distance input key for inputting a distance. A running speed at which the user of an age can keep running continuously is calculated from the pulse frequencies stored in the pulse frequency memory and age data input by the age input key. Further, a time is calculated which the user requires to run the distance inputted by the distance input key at the calculated running speed. The calculated time is displayed on a display unit of the time calculating device.

Time calculating device

An electronic stop watch measures an elapsed time, and stores each measured elapsed time together with measurement date data. The measurement date data is also read out and displayed when the stored elapsed time is read out and displayed, so as to represent when the readout and displayed elapsed time was measured.

An exercise measuring instrument according to the present invention employs an acceleration sensor which comprises a piezoelectric piece having a pair of piezoelectric elements stuck to each other. An output waveform of the acceleration sensor is supplied to an amplifier, gain of which is changed in accordance with an exercise mode selected out of a walking mode, an exercise-walking mode and a jogging mode, and thereby an output level of the amplifier is kept at somewhat an equal voltage level, although the voltage level of the output waveform of the acceleration sensor is different between the exercise modes. This improvement allows an accurate measurement of exercise.

An electronic timepiece comprises time count circuit for counting a reference signal to obtain present time data, item data storage for storing a plurality of item data, and external operation switch for inputting at least one of alarm time data and identification data corresponding to the plurality of item data stored in the item data storage. An alarm data storage stores the alarm time data and the identification data input by the external operation switch. A read controller detects a coincidence between the present time data obtained by the time count circuit and the alarm time data stored in the alarm time data storage and for reading out, from the item data storage, item data corresponding to the identification data stored in the alarm time data storage. A display displays the item data read out by the read controller.
