There is. The plurality of holders 5 are arranged in correspondence with the horizontal row of sockets arranged in the measuring instrument groups a to n, respectively. In other words, a plurality of electronic components 2 are held in a group of 5 holders on one transport pallet 4.

The conveyor pallet 4 is sequentially and intermittently conveyed below the measuring instruments a, b, . In this example, sprockets 6 and 11!
The conveyor 7 constitutes a conveying means.

The electronic component 2 used in this embodiment is of a type called a flat type in which the shaped glue 21 protrudes from two directions (see FIG. 2).

The holder 5 that holds the electronic component 2 will be explained with reference to FIG. 3. That is, the holder 5 is formed by molding resin into a substantially prismatic body. A recessed groove 51 (accommodating part) extending in the longitudinal direction is formed on this upper surface, and the package part 2 of the electronic component 2 is placed in this recessed groove 51.

Two protrusions 53 are formed at regular intervals on the upper surface of each end of the standing wall 52 on both sides of the groove 51, and the area between the two protrusions 53 is the area between the leads 21 of the electronic component 2. The support portion 54 supports the. Furthermore, the jig 57 (see Fig. 5) that holds the holder 5 has a built-in magnet 55 that faces the component to prevent the electronic component 2 from shifting due to shock when intermittent one-shell feeding is stopped. I'm letting you do it. Such a holder 5 is designed to hold two electronic components 2, and the electronic components 2 are each set upside down as indicated by the arrows in FIG. Reference numeral 56 indicates a screw hole for fixing the holder.

Furthermore, the sockets 3 provided in the measuring instrument groups a to n will be explained with reference to FIGS.
