Human body detection device and electronic equipment using the same

A human body detection device comprising:

• a pyroelectric-type sensor configured to output a signal upon detecting presence of a human body;
• an infrared distance-measuring sensor configured to detect a distance to the human body in response to receipt of the output signal from pyroelectric-type sensor;
• and
• a body casing in which at least the pyroelectric-type sensor and the infrared distance-measuring sensor are housed,
• the infrared distance-measuring sensor including:
• a plurality of infrared-ray emitting devices which are arranged in various directions of infrared emission so as to cover a detection range of the pyroelectric-type sensor;
• and
• a position sensing device which has one light receiving surface corresponding to the plurality of the infrared-ray emitting devices for making infrared rays reflected by the human body incident thereon and which outputs a signal indicating a distance to the human body according to a position of the incident light on the light receiving surface, wherein
• the position sensing device is housed in one housing, and
• a toroidal lens is arranged at a location on a front surface of the body casing corresponding to the light receiving surface of the position sensing devices.
