An antenna device has a first antenna element supporting a low frequency band and a second antenna element supporting a high frequency band. The first antenna element and the second antenna element are disposed so as to face to each other, on the wiring board of a radio device, and at positions separated from each other by a predetermined distance. The distance between the first antenna element and the ground of wiring board is longer than the distance between the second antenna element and the ground of the wiring board. The antenna device supports two frequency bands with the first antenna element and the second antenna element.

A non-contact thermometer uses a pyroelectric infrared sensor which makes it possible to measure temperatures of an object having a large area required to be measured, and at a plurality of points. The thermometer sets up a reference position without using a position detecting switch and also improves the accuracy of measuring the temperature due to its increased amount of incident infrared rays transmitted as a result of reducing the motor speed and extending the time of measurement at the point where infrared rays of the object to be measured is to be detected. The thermometer's stepping motor is fed with its operation step input and brought to a stop at the reference exciting phase of the motor which has been set up in advance. The whole measurement operation thereafter is arranged to proceed, starting from the above exciting phase serving as the reference, at which point the motor was brought to a stop.
