Abstract: An automatic mounting apparatus mounts chip-type electronic components on a printed circuit board. A plurality of chip-type electronic components are held at nearly equal intervals in the longitudinal direction of a tape, and this tape is drawn out from a tape reel to a feedout unit accommodated in a reel cassette together with the tape reel. The chip-type components are picked up one by one in sequence from the tape at the position of the feedout unit by a vacuum chuck, being placed on a predetermined position on the printed circuit board by this vacuum chuck. In the vicinity of the end of the tape holding the chip-type electronic components, a residual quantity indicator capable of mechanical detection is formed. When this residual quantity indicator is detected, the controller drives an alarm device such as, for example, a buzzer or a light emitter to inform that the chip-type electronic components on the tape will soon run out.
