  • Patent number: 10257970
    Abstract: A feeder and a feeder control method, as well as an electronic component device, reliably engaging a supply tape in a loading operation even if there is an accumulated pitch error between sprocket holes. Third, second and first sprockets are arranged successively from an insertion port. The sprocket hole on a forward end portion of the inserted supply tape is fitted with a third tooth of the third sprocket in the loading operation. The supply tape is rotated by rotation of the third sprocket until fitting with a second tooth of the second sprocket, and the rotation of the third sprocket is stopped after the second tooth fits with the sprocket hole on the forward end portion.

  • Patent number: 9674995
    Abstract: To provide a component supply unit capable of reliably cutting a cover tape and reliably exposing an electronic component when using a new storage tape and supplying the electronic component. A tape processing unit includes a cutter successively cutting a cover tape of a storage tape along a traveling direction following traveling of this storage tape. The cutter includes a blade portion having an angular blade portion so inclined frontwardly downward that a blade is angularly formed, and an upper C-chamfered surface (upper worked surface) which is a flat portion whose width in the horizontal direction gradually narrows from a lower end upwardly to reach the angular blade portion on an upper end formed on a forward end portion of this blade portion.
