Abstract: For the purpose of realizing a display method for a portable electronic measuring device that allows the user to know his condition more easily and in greater detail by making it easy for him to read the display of measured results even if the display device is limited in size due to its portability, a bar graph is displayed in dot display area (134) of liquid crystal display device (13) of the portable pulse measuring device which extends up at each time interval according to the absolute value of the pulse rate after the measurement of time is started and until the pulse rate reaches a prescribed range, and after the pulse rate reaches the prescribed range, a bar graph is displayed that extends in the positive direction or the negative direction at each time interval according to the difference from the prescribed reference pulse rate. When temporal changes in the pitch during running are displayed in dot display area (134), they are displayed in a segmented graph.

Abstract: To achieve a multiple function portable electronic device providing improved ease of use by enabling the operation of selected functions to be sustained even while replacing the battery, switch end 190 is pushed out from battery housing hole 509 to one side by battery 59 when battery 59 is loaded, and is pushed by spring member 197 into battery housing hole 509 inside watch case 11 of the wristwatch-type pulse wave measuring device when battery 59 is removed from battery housing hole 509 after removing the battery cover. Switch end 190 thus automatically inputs the terminal voltage of a backup capacitance element from signal input terminal 510 to the IC. This causes the wristwatch-type pulse wave measuring device to switch from the normal operating mode to an energy conservation mode.

Abstract: A wrist-worn portable electronic device comprises a main unit having a display member for displaying information including time, etc., a wrist band connected to the main unit for allowing a user to wear the device on the wrist, and a connector mechanism for allowing signals to be input to the main unit. The connector mechanism comprises a connector member disposed on an edge of the main unit at a 6 o'clock or 12 o'clock position of the main unit and a connector piece for removably coupling to the connector member. The connector member includes a first terminal group comprising a plurality of terminals. The connector piece includes a second termination group comprising a plurality of terminals for electrically connecting to the first terminal group. The second terminal group receives signals for inputting to the main unit. In the wrist-worn portable electronic device, the connector mechanism allows easy attachment and detachment of a cable, etc., to the main unit.

Abstract: The invention provides a wrist-worn pulse wave measuring device capable of outputting data measured by the wrist-worn pulse wave measuring device to an external data processing device without using a large device body. In the pulse information processing apparatus, a connector piece of a sensor unit is mounted to a connector of a wrist-worn pulse wave measuring device when measuring the pulse. A data transmission connector piece is mounted to the connector of the pulse wave measuring device when transmitting data with a data processor. Whether the operating mode is the pulse measurement mode or the data transmission mode is determined by a signal discriminator which discriminates the signal input from the connector of the pulse wave measuring device.

Abstract: A pulse rate monitor allows a user's pulse rate to be measured and displayed continuously while removing the inaccuracies caused by motion of the user, by detecting the motion level and determining whether an accurate pulse rate measurement can be taken based upon the detected motion. The most recent accurate pulse rate measurement is stored in memory and the pulse rate is estimated when a user is undergoing too much movement for obtaining accurate measurements by using the stored pulse rate and the magnitude of the detected movement.

Abstract: For the purpose of providing, by only improving the shape of the device body, at a low cost and without impairing user comfort a wrist-worn portable device and a wrist-worn pulse wave measuring device whereby the device body does not turn unnecessarily around the wrist. A wrist-worn pulse wave measuring device 1 attaches device body 10 by means of wrist band 12 to the wrist, and attaches sensor unit 30 to the base of a finger by means of a band for holding the sensor. At the end of cable 20 leading from sensor unit 30 is formed connector piece 80, which is attached by simply sliding connector 70 in the direction of twelve o'clock. Because device body 10 has a turning stop 108 forming an approximately 115.degree. angle to the back, device body 10 will not turn unnecessarily even if it is turned in the direction of six o'clock or twelve o'clock on a wristwatch.
