Abstract

A mobile terminal (10) of the present invention has a sensor (15) for detecting a pulse, in an upper end portion of a back surface of a main body of the mobile terminal (10). The sensor (15) is constituted by a light-emitting element and a light-receiving element. A position of the sensor is determined so that a force acting on the sensor falls within a range from 50 gf to 200 gf in a case where the mobile terminal is supported at its lower end portion and at the sensor by a fingertip. Thus, the present invention provides the mobile terminal (10) which can be always carried with a user and which realizes easy and stable pulse measurement.

Claims

1-14. -14. (canceled)

15. A mobile terminal comprising:

a main body housing an electronic device;

a display section or an operation section, being provided on a first surface of the main body; and

a sensor for detecting a pulse, the sensor being provided on a second surface of the main body, the sensor having a light-receiving element,

the mobile terminal having a weight of not more than 200 gf.

16. The mobile terminal as set forth in claim 15, having a weight of not less than 50 gf.

17. The mobile terminal as set forth in claim 15, comprising:

an attitude detector sensor for detecting an attitude of the mobile terminal; and

a control section for (i) performing determination as to whether or not a direction of the sensor matches a gravitational direction, and (ii) controlling, in accordance with the determination, (I) notification of information or (II) pulse detection, the control section performing the determination on the basis of the attitude of the mobile terminal, the attitude being detected by the attitude detector sensor.

18. The mobile terminal as set forth in claim 17, further comprising a second display section on the second surface of the main body,

in a case where the control section determines that the direction of the sensor does not match the gravitational direction, the control section notifying, via the second display section, a user that the sensor is not properly used.

19. The mobile terminal as set forth in claim 17, comprising a pulse sensor axis storing section, the pulse sensor axis storing section storing information indicative of a direction, with respect to the main body, of an axis of the sensor,

the attitude detector sensor being a three-dimensional acceleration sensor,

in order to notify a user of whether or not the mobile terminal is in a proper attitude, the control section determining, when the sensor detects a pulse, whether or not the axis of the sensor is directed in the gravitational direction, on the basis of (a) information indicative of the attitude of the main body of the mobile terminal, the attitude being detected by the attitude detector sensor, and (b) pulse sensor axis information supplied by the pulse sensor axis storing section.

20. The mobile terminal as set forth in claim 19, wherein the control section determines that the mobile terminal is in the proper attitude in a case where a direction of the axis of the sensor falls within a range from 0°

to 45°

with respect to the gravitational direction, and a force acting on the sensor is not less than 50 gf when the mobile terminal is tilted.

21. The mobile terminal as set forth in claim 15, wherein the sensor is provided in a barycentric position of the mobile terminal, which barycentric position the mobile terminal has on the second surface.

22. The mobile terminal as set forth in claim 15, wherein:

the main body includes a plurality of casings including the first casing and the second casing;

adjustment of a position of the first casing with respect to a position of the second casing brings the sensor to or near a barycentric position of the mobile terminal, which barycentric position the mobile terminal has on the second surface.

23. The mobile terminal as set forth in claim 15, wherein the sensor has a light-emitting element.

24. The mobile terminal as set forth in claim 15, wherein the sensor is provided to an end portion of the second surface of the main body.

25. A method for measuring pulse of a fingertip by using a measurement section having a pulse detector sensor, the pulse detector sensor having a light-receiving element,

the method comprising the step of measuring pulse in such a manner that the measurement section is put on the fingertip so that the pulse detector sensor and the fingertip may face each other,

the measurement section having a weight of not more than 200 g.
