Abstract: PROBLEM TO BE SOLVED: To prevent a false distance measurement from occurring due to shifting of an object in relation to radiation light.
SOLUTION: A light blocking section made up of a light blocking resin 16 having a window 17 is disposed at a light emitting section which contains a light emitting chip 12 mounted on a lead frame 11, thereby blocking a spread portion of radiation light caused by reflection light from the lead frame 11. As a result, even in the case the object which should be in the center section of the radiation light, is shifted along an alignment direction of the light emitting chip 12 and a light receiving chip 13 so as to be deviated from a portion of the radiation light, since the spread portion of the radiation light is blocked and does not exist there, reflection light of the spread portion of the radiation light from the object is prevented from entering the light receiving chip 13. Therefore, the false distance measurement is prevented from occurring due to the shifting of the object in relation to radiation light.

Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive object detector of high reliability about a stable operation for a long period, and of low limitation in view point of use, and provide an electronic equipment provided therewith. SOLUTION: Five LEDs (infrared ray emitting elements) 3-0 to 3-4 are arranged to define a plane in a view from emission directions of the five LEDs 3-0 to 3-4. The five LEDs 3-0 to 3-4 emit a near infrared ray I1. A reflected ray I1' generated by an inspection object H gets incident thereby on one photoreception face of a PSD 4 through a convergence lens 6. The PSD 4 outputs a signal expressing a distance up to the inspection object H in response to a position of the incident ray within the photoreception face. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide an optical range finding sensor capable of preventing measuring precision of a distance from getting worse along with a measured object getting distant, without bringing size enlargement and cost increase.
SOLUTION: Near infrared wavelength of rays emitted from an LED 1 are brought into a parallel beam by a light emitting side lens 2 to be projected to the measured object 10. A reflected beam by the measured object 10 gets incident into a PSD 5 via a photoreception side lens 3 and a prism 4. Since the prism 4 has a refractive characteristic of making a ratio of a variation of an emission angle to a variation of an incident angle get large along with the incident angle of the beam getting small, the variation of the emission angle of the emission beam from the prism 4 can be made substantially equal between the case where the measured object 10 is located in a near distance position and the case where the measured object 10 is located in a distant position, when the position of the measured object 10 is changed. The measuring precision when the measured object 10 is located in the distant position is thereby made substantially equal to that when the measured object 10 is located in the near distance position.

Abstract: PROBLEM TO BE SOLVED: To provide an optical ranging sensor which has no sound, is relatively good in long term stability, can reduce the size and cost and has relatively high measurement accuracy.
SOLUTION: The light emitted from a plurality of LEDs 51 to 55 is transmitted through one emitting lens 1 and reflection light reflected with a detection target 32 is received with PSD4 through a receiving lens 2. The direction of the target 32 is detected by the light emission direction from the LEDs 51 to 55 and the distance to the target 32 is detected based on the reception position of the reflection light on the receiving surface of PSD4. By receiving far infrared rays L10 with a pyroelectric sensor 30, whether the detected target 32 is a human body or not is detected. Since emission light of plurality of LEDs 51 to 55 are transmitted in the one receiving lens 1, reduction of the size and cost of the optical ranging sensor can be attained.
