Abstract: PURPOSE:To enable execution of efficient three-dimensional measurement by a method wherein a measuring light for distance measurement is applied to at least the whole image pickup area of an image pickup means by a wide-area irradiation means. CONSTITUTION:A light-source and processor apparatus 5 supplies an illuminating light and a measuring light from an ordinary illuminating light generating means 43 and a measuring light generating means 44 to an image guide connector 18b through a half prism 42. These illuminating light and measuring light are transmitted by an image guide 17, the irradiation angle thereof is widened by a prism 27 and they illuminate a subject 25 widely over the whole of an image pickup area of CCD 32 as an image sensing element. A projective lens 26 forms a minute light spot on the surface of the subject 25 without expanding the light beam of the measuring light. The image of the subject 25 illuminated in the wide area by the illuminating light is formed on the image sensing surface of the CCD 32 by an objective lens 31. The CCD 32 is connected to a distance computing circuit 38 and thereby indentation of the subject 5 is computed.

Abstract: PROBLEM TO BE SOLVED: To uniformize deformation of a spring by arranging a push button consisting of an insulating material so as to laterally straddle the support part of a conductive from above by a pair of mutually separated leg parts thereof, and touching it to a spring larger in width than that of the support part, which presses the lower surface of the support part on the outside of the support part. SOLUTION: A pair of leg parts 31 of a push button 6 straddles a support part 37A of a terminal 11 and abut on both edges of a spring tip part 42A, which extend sideward over both lateral sides of the support part 37A. When the push button 6 is depressed from above, the inclined surface 6A is descended until it touches the top wall 37 of the terminal 11. At that time, a horizontal flat part 42 of a spring 13 is depressed down to a position shown by a virtual line by the leg parts 31 to separate the support part 37A of the terminal 11 from the spring tip part 43A. According to this, a conductor 10 inserted through the hole 5 of a housing body can be inserted between the support part 37A and the spring 13. Since the push button 6 presses both edges of the spring with the leg parts, the spring can be deformed uniformly as a whole in the lateral direction.
