Claim:
1. A component-recognizing apparatus comprising a scanning unit which is installed to a movable head unit having a plurality of suction-holding nozzles in a raw, each of the plurality of suction-holding nozzles being capable of suction-holding an electronic component, the scanning unit being adapted to be displaceable in a direction relative to the plurality of suction-holding nozzles, the scanning unit being operable to capture an image for image recognition of suction-held conditions of the electronic component being suction-held by each of the plurality of suction-holding nozzles, said scanning unit including: a first optical path changing member which is adapted to be located beneath the plurality of suction-holding nozzles and is operable to reflect the optical path directed downwardly from the plurality of suction-holding nozzles in a lateral direction during the image-sensing operation; a second optical path changing member operable to further reflect the reflected optical path in another direction so that the reflected optical path directs upwardly at a given elevation angle inclined relative to both horizontal and vertical planes; and image-sensing means including an image sensor in the form of a line sensor provided in the image-sensing means, the image sensor being operable to capture an image of a lower surface of the electronic component being suction-held by each of the plurality of suction-holding nozzles through the first and second optical path changing members, the scanning unit being adapted to be moved along the row of suction-holding nozzles beneath the nozzle unit to capture an image of suction-held conditions of the electronic component being suction-held by each of the suction-holding nozzles, in a sequential manner, and the image-sensing means being disposed along the optical path changed by the second optical path changing member, such that the image-sensing means are inclined relative to both horizontal and vertical planes, the image sensor being arranged inside of the image-sensing means to be inclined with respect to a horizontal direction in such a manner that a direction of the image sensor is set approximately perpendicular to a movement direction along which an image of the electronic component is moved on the image sensor as the scanning unit moves along a row of the suction-holding nozzles.
