A tape erroneous mounting detection system includes sensors provided to the plurality of tape feeders, a reader configured to read identification information from a recording part which is provided to a reel, and a memory part configured to store part verification information. The tape erroneous mounting detection system also includes a part verification part configured to determine whether or not the tape is mounted on the tape feeder at the set position, and to perform verification updating processing, and a tape erroneous mounting detection part configured to perform erroneous mounting detection processing where the tape erroneous mounting detection part identifies the tape feeder on which the tape is mounted based on the tape presence or absence information and the output from the sensor, and the tape erroneous mounting detection part detects that the tape mounted on the tape feeder is erroneously mounted.
