Abstract:
1. A hand-held color measurement device comprising: a housing, wherein said housing accommodates a measurement array and an electronic controller and comprises a housing base and a measurement opening through which a measurement spot on a surface of a measurement object is illuminated and the measurement light reflected by the measurement spot is picked up, wherein the measurement array comprises an illumination array for applying illumination light to the measurement spot in at least one illumination direction, and a pick-up array for detecting the measurement light in at least one observation direction, wherein the at least one illumination direction and the at least one observation direction lie in a common illumination-observation plane, and wherein the housing base of the housing comprises a bearing means for positioning the device on the surface to be gauged, wherein the bearing means is embodied as a three-point bearing having three substantially pin-shaped support members, each comprising a bearing area, wherein the bearing areas of a first and a second one of the support members lie in a base line which is in the illumination-observation plane at a distance of at most 2 mm from it, wherein the bearing area of a third one of the support members is arranged at a distance from the illumination-observation plane which is greater than the distance of the first and/or second one of the support members, and wherein the bearing areas of the support members lie substantially in a base plane which is perpendicular to the illumination-observation plane, wherein a projection of the center of gravity of the device in relation to the base plane lies in a direction perpendicular to the base plane between the bearing areas of the support members, and wherein the projection of the center of gravity lies within a triangle defined by the three bearing areas of the three support members, whereby a stable stand of the hand-held color measurement device is achieved.
