A mounter is operable to sequentially detect feed amounts of a motor at respective times when respective electronic components held by a tape reach a pickup position, while rotating a sprocket 52 of a tape feeder 50 360 degrees or more, and store the feed amounts in correspondence with respective pins 54 drivingly feeding the tape. This makes it possible to reliably duplicate a state when each electronic component reaches the pickup position, based on a feed amount itself of the motor at a time when each electronic component truly reaches a pickup position. |
