  • Patent number: 7743913
    Abstract: When the operation of an electronic component conveying apparatus is to be stopped, application of a negative pressure to through holes is stopped, and a compressed air blowing mechanism blows compressed air from an exhaust nozzle with a pressure greater than a pressure applied during the operation of the electronic component conveying apparatus. Accordingly, an air curtain is generated at opening portions of the through holes on the guide member side, and the air curtain prevents electronic components from entering the through holes. The electronic components remaining in the through holes located downstream of the position of the exhaust nozzle in a conveying direction are conveyed to a measurement section so as to enable measurement of the characteristics thereof, and then discharged by a discharging mechanism in a discharge section. Thereafter, rotation of a conveying member is stopped.
