A component mounting apparatus comprises a hollow rod communicated to a source of vacuum and having a suction head for picking up generally rectangular articles one at a time by the effect of a suction force. At least one pair of finger members for clamping and releasing the articles which has been sucked onto the suction head are provided for effecting a correction in position of the article relative to the suction head. Each of the finger members has an inclined end face which is adapted to support the article sucked onto the suction head from below in engagement with the opposite lower edges of the article.
