整するオリフイスである。Conventional configuration and its problems The conventional detection method when chip-type electronic components are vacuum-adsorbed with a nozzle is as follows: As shown in Figure 1, the tube 1 connected to the vacuum generator is divided into two. The pipes 2 and 3 are branched to form a pneumatic bridge circuit, one of which is opened to the atmosphere through a nozzle 4 and the other through a throttle valve 5. When the chip-type electronic component 6 is attracted to the nozzle 4, the degree of vacuum on the tube 2 side increases,
A magnetic float 7 placed between tubes 2 and 3 is drawn up towards tube 2. At this time, the ON and OFF states of reed switches 8 and 9 provided near the float are switched, and an output is generated indicating that the chip-type electronic component 6 is being normally attracted. 10 and 11 are orifices that adjust the air flow rate in the pipe line.

As shown in FIG. 3, there are cases where detection is impossible due to chip-type electronic components. FIG. 2 shows an example in which a rectangular chip-type electronic component 6' is suctioned, and a is suctioned to the nozzle 4 in a normal posture. b is a state in which the chip-type electronic component 6' is sucked horizontally;
A gap 12 is created between the nozzle 4 and the chip-type electronic component 6'. Figure 2 c, d, and e are examples of a cylindrical chip-type electronic component 6'' being sucked into the nozzle 4, and c is a normal suction state with no gap between the nozzle 4 and the chip-type electronic component 6''. 12' is made. In d, the chip type electronic component 6'' is vertically attracted and no gap is created. In e, the chip type electronic component 6'' is attracted in an oblique manner, and a gap 12'' is created. Figure 3 shows a in Figure 2,
