Component verification method and component verification system

A component verification method for verifying whether or not a stored component of a subsequent tape subsequently inserted into a tape feeder, in a state where a preceding tape precedingly sent out of two carrier tapes sequentially sent one after another is set, for component replenishment is correct, in a component mounting apparatus that picks up components, which are supplied from carrier tapes tape-fed by a plurality of tape feeders arrayed in a component supply unit, by a mounting head to mount the components on a substrate,

• the component verification method comprising:
• a component ID reading process of reading a component ID corresponding to the stored component of the subsequent tape;
• a tape insertion detecting process of detecting that the subsequent tape has been inserted into the tape feeder;
• a feeder specifying process of specifying a tape feeder in which the insertion of the subsequent tape has been detected;
• a component verifying process of verifying whether or not a correspondence relationship between the read component ID and the specified tape feeder is correct;
• and
• a re-verification requesting process of requesting re-execution of the verification to a worker if it is detected that the subsequent tape has fallen from the tape feeder after the component verifying process.
