A component mounting machine comprising: a feeder device that has a tape feeding mechanism which feeds out a carrier tape including a bottom tape that stores components in respective multiple component storage sections and a cover tape that is adhered to the bottom tape and covers the component storage sections , and a tape peeling mechanism which has a tape peeling blade advancing between the bottom tape and the cover tape as the carrier tape is fed out and carries out peeling, and supplies the component from the component storage section at a component supply position ; a component transfer device that has a mounting head which holds a suction nozzle which sucks the component at the component supply position , and mounts the component on a board (K), and a head driving mechanism which drives the mounting head ; a peeling start determination section that determines whether or not the tape peeling blade advances between the bottom tape and the cover tape and the peeling starts, after the leading end of the carrier tape is fed out up to the tape peeling blade and before the suction nozzle starts a suction operation at the component supply position ; and a recovery function section that carries out a recovery operation in which the recovery function section returns the leading end of the carrier tape temporarily to the front of the tape peeling blade and feeds out the carrier tape again in a case where it is determined that peeling is not started by the peeling start determination section, and wherein the peeling start determination section is configured to include a board camera that is provided in the mounting head and images a position fiducial mark of the board (K), and an image determination section that images the carrier tape by moving the board camera in a range from the tape peeling blade up to the component supply position , performs image processing on the captured image, and determines whether or not peeling starts. a feeder device that has a tape feeding mechanism which feeds out a carrier tape including a bottom tape that stores components in respective multiple component storage sections and a cover tape that is adhered to the bottom tape and covers the component storage sections , and a tape peeling mechanism which has a tape peeling blade advancing between the bottom tape and the cover tape as the carrier tape is fed out and carries out peeling, and supplies the component from the component storage section at a component supply position ; a component transfer device that has a mounting head which holds a suction nozzle which sucks the component at the component supply position , and mounts the component on a board (K), and a head driving mechanism which drives the mounting head ; a peeling start determination section that determines whether or not the tape peeling blade advances between the bottom tape and the cover tape and the peeling starts, after the leading end of the carrier tape is fed out up to the tape peeling blade and before the suction nozzle starts a suction operation at the component supply position ; and a recovery function section that carries out a recovery operation in which the recovery function section returns the leading end of the carrier tape temporarily to the front of the tape peeling blade and feeds out the carrier tape again in a case where it is determined that peeling is not started by the peeling start determination section, and wherein the peeling start determination section is configured to include a board camera that is provided in the mounting head and images a position fiducial mark of the board (K), and an image determination section that images the carrier tape by moving the board camera in a range from the tape peeling blade up to the component supply position , performs image processing on the captured image, and determines whether or not peeling starts. <EOS>
