Abstract: A component supplying apparatus comprises a tape guide surface facing a lower surface of the carrier tape, a preceding tape contact part climbing onto a upper surface of the preceding carrier tape, and a subsequent tape blocking part configured to wait on the upstream side of the preceding tape contact part in a tape feeding direction while keeping a distance from the tape guide surface so as to enable the carrier tape to pass between the subsequent tape blocking part and the tape guide surface, and to move downwardly toward the preceding carrier tape when the preceding tape contact part is climbed onto the preceding carrier tape. The subsequent tape blocking part keeps the subsequent carrier tape waiting by contacting a front end of the subsequent carrier tape stacked on the preceding carrier tape onto which the preceding tape contact part climbs.

Abstract: A mounting head is provided with suction nozzles, image capturing cameras, and a movable mirror unit. When the mirror unit is placed at an advance position, mirrors advance into a viewing field of the image capturing cameras and refract an optical axis for image capturing, so that the image capturing cameras can capture images of tips of the suction nozzles and/or held components. When the mirror unit is placed at a retreat position, the mirrors retreat from the viewing field of the image capturing cameras, so that the image capturing cameras can capture images of component supplying positions and mounting positions.

Abstract: An X-Y robot having a structure that linearly deforms along an X-axis direction and a Y-axis direction, a camera reference mark, and a control unit are provided. The X-Y robot causes no displacement of warp or the like and linearly deforms along only the X-axis direction and the Y-axis direction even if heat takes effect due to continuous operation. Therefore, if the amount of expansion and contraction of the X-Y robot due to heat is obtained by picking-up an image of the camera reference mark by a board recognition camera and the component placing position is corrected on the basis of the amount of expansion and contraction, then an electronic component can be mounted in a prescribed position or almost in the prescribed position.
