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.

Feeder for an electronic component

A component supply device loaded with a component supply tape for exposing and supplying an electronic component from the component supply tape with respect to a component mounting device mounting the electronic component on a substrate includes a replenishing unit performing replenishment of a new component supply tape when a preceding component supply tape is exhausted and a sensor senses exhaustion of the preceding component supply tape while a confluent portion where a channel for the preceding component supply tape and a channel for the new component supply tape join with each other is formed between the sensor and the replenishing unit. A buckling prevention mechanism moves in response to an operation of the preceding component supply tape or the new component supply tape for preventing buckling when the new component supply tape is transported to the component supply device by the replenishing unit is arranged on the confluent portion.

Component supply device and component mounting device

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.
