ABSTRACT:
An electronic-component supplying cartridge is provided which includes a movable and an immovable jumping-out-preventing member and is free from jumping of electronic components out of electronic-component accommodating pockets, changing of posture of the components, or standing-up of the components due to suction. A shutter 210 is attached to a cover 82 fixed to a cartridge frame, such that the shutter 210 is movable relative to the cover 82 in the tape feeding direction. The shutter 210 includes a connection portion 214 having a groove 222 opening at a downstream-side end thereof as seen in the feeding direction, and a pair of movable jumping-out-preventing strips 228. When the shutter 210 is moved to a second position thereof, the strips 228 are received in receiving recesses 200, respectively. When a component carrier tape is fed, the shutter 210 is moved to a first position thereof where the strips 228 cover a component accommodating pocket fed to an electronic-component picking-up position. A component-suction nozzle is moved downward in synchronism with the retracting movement of the shutter 210 to the second position, so that the nozzle holds by suction an electronic component through the groove 222 before completion of the retracting movement of the shutter 210. Since the component is not freed before being held by the nozzle, the component does not jump out of the carrier tape.
