Problems solved by technology

[0012] Furthermore, when performing azimuth processing, since the user performs non-contact communication unconsciously or consciously, by bringing the electronic device close to an electromagnetic wave emission source such as a read / write device, the geomagnetism detection by the geomagnetic sensor may also malfunction, so also Hope this status can be reported

Embodiment approach

[0246] Figure 6 It is an external view of a bar-type mobile phone 1A without opening and closing the casing according to the second embodiment showing the first viewpoint of the present invention.

[0247] The bar-type mobile phone 1A has a key input unit 10A and a display unit 12A on the outer surface, and accommodates a geomagnetic sensor 170 and components described with reference to FIG. 3 inside.

[0248] However, in a bar type mobile phone that does not open and close the housing, the magnetic sensor 180 and the magnet 190 are not provided as shown in FIG.

[0249] In addition to the opening and closing processing of the frame, Figure 6 Transaction processing and azimuth processing (electronic compass processing) of the shown bar-type mobile phone 1A are also the same as those of the foldable mobile phone 1 of the first embodiment.

[0250] Embodiments of the first viewpoint of the present invention are not limited to the above-mentioned examples, and various modifie...

no. 3 approach

[0374] A foldable mobile phone 1A as an embodiment of the first viewpoint of the present invention is shown in Figure 6 can be used as the third embodiment of the second aspect of the present invention.

[0375] As shown in FIG. 12 , in the bar type mobile phone 1A that does not open and close the housing, the magnetic sensor 180 and the magnet 190 are not provided, and the housing opening and closing detection processing unit 160 is not provided. The above-mentioned "forced removal of transaction processing restrictions by non-contact communication) (2)" is not appropriate.

[0376] In addition to the opening and closing detection processing of the frame, Figure 6 Transaction processing and azimuth processing (electronic compass processing) of the shown bar-type mobile phone are the same as those of the foldable mobile phone 1B according to the first embodiment of the second aspect of the present invention.

Abstract

Provided is an electronic device of a mobile telephone or the like that is possible to perform a direction indication as well as non-contact communication by making use of an electromagnetic wave, when terrestrial magnetism detection processing by means of a terrestrial magnetism sensor and the non-contact communication by means of a electromagnetic wave are carried out at the same timing, there is a possibility that terrestrial magnetism data detected by the terrestrial magnetism sensor are not precise because of influence of the electromagnetic wave. It is necessary to take its measures, accordingly. Further, when terrestrial magnetism detection processing by means of a terrestrial magnetism sensor and the non-contact communication by means of a electromagnetic wave are carried out at the same timing, either the direction processing based on a detected signal of the terrestrial magnetism sensor or the non-contact communication processing is restricted.

Description

technical field [0001] The present invention relates to an electronic device capable of non-contact communication using electromagnetic waves and a control method thereof, in which a magnetic sensor is installed in a mobile phone to detect geomagnetic data, report azimuth information calculated from the geomagnetic data, and implement non-contact communication using electromagnetic waves. [0002] In particular, the present invention relates to a technique for restricting azimuth processing or restricting noncontact communication processing when azimuth processing and noncontact communication processing using a geomagnetic sensor compete with each other. Background technique [0003] Patent Document 1 discloses electronic compass (orientation display) technology, that is, a geomagnetic sensor is installed on a mobile device, and the current orientation of the mobile device is reported according to the detection signal of the geomagnetic sensor, and position information such a...
