At this time, the vibration frequency of the electromagnetic motor 136 is adjusted so that the electronic component that has entered the conveying groove 132 floats obliquely forward. For this reason, the transport lane 106 repetitively vibrates in the front-rear direction at a high frequency, so that the electronic component that has entered the transport groove 132 advances forward in small steps.
- air flow paths 146 are formed in the conveying groove 132 at roughly seven equal positions in the front-rear direction. Air is jetted into the conveying groove 132 by the operation of the air pump 142 of the jetting device 108 .
- the air flow path 146 passes obliquely upward forward from the bottom surface of the transport lane 106 and opens at the bottom surface of the transport groove 132. Therefore, the air jetted into the transport groove 132 flows through the transport groove. It flows inside from the rear to the front. As a result, the electronic component that has entered the transport groove 132 advances forward.
