The plurality of holders 5 are arranged so as to correspond to the socket arrangement state of the measuring instrument groups a to n in a horizontal row. That is, a plurality of electronic components 2 are held in a group of holders 5 on one transfer pallet 4. The transport pallet 4 is intermittently transported below the measuring instrument a, the measuring instrument b ... Measuring instrument n by a transporting conveyor 7 which is rotated by a sprocket 6. In this embodiment, the sprocket 6 and the conveyor 7 constitute a conveyor.

The electronic component 2 applied in this embodiment is of a type in which leads 21 having a shape called a flat type project from two directions (see FIG. 2). The holder 5 for holding the electronic component 2 will be described with reference to FIG. On the other hand, the holder 5 is formed by molding a resin into a substantially prismatic body. A recessed groove 51 (a housing portion) extending in the longitudinal direction is formed on the upper surface, and the package portion 22 of the electronic component 2 is housed in the recessed groove 51. Two convex portions 53 are formed on the upper surface of each end of the standing wall 52 on both sides of the concave groove 51 at regular intervals, and the area between the two convex portions 53 is the lead 21 of the electronic component 2. It is supposed to be a support portion 54 for supporting the. Further, the jig 57 (see FIG. 5) for holding the holder 5 has a built-in magnet 55 as a holding means for attracting and holding the package portion 22 of the electronic component 2 facing the component. The electronic component 2 is prevented from being displaced due to the shock. Such a holder 5 holds two electronic components 2, and the electronic components 2 are set upside down as shown by arrows in FIG. Reference numeral 56 is a screw hole for fixing the holder.

Further, the socket 3 provided in the measuring instrument groups a to n will be described with reference to FIGS. 4 (a) and 4 (b). The socket 3 is made by molding a resin into a substantially rectangular parallelepiped shape, and has screw holes 31 for attaching to the measuring instrument groups a to n at its four corners. A concave groove 32 extending in the longitudinal direction is formed in the central portion of the socket 3. A plurality of storage recesses 33 are formed at the center of the socket 3 on both sides of the recessed groove 32, and the measurement terminals 34 are stored in the storage recesses 33 so that the upper ends thereof are exposed.

Next, the operation will be described.

First, the electronic component 2 is set in the holder 5 as shown by the arrow in FIG. The carrier pallet 4 to which the holder 5 is attached is placed on the carrier conveyor 7, and the carrier pallet 4 is moved by the carrier conveyor 7 at an appropriate pitch so that the holder 5 group of the carrier pallet 4 is located below the measuring device a group. Allow intermittent transportation. When the intermittent conveyance is stopped, the mounting base 1 is lowered to bring the measuring terminals 34 of the socket 3 of the measuring device a into contact with the leads 21 of the electronic component 2 (fifth contact).
See figure). As a result, the measuring instrument a group and the plurality of electronic components 2
Signals are exchanged by electrically connecting and. When the measurement is completed, the mounting base 1 is raised to connect the measuring terminal 34 of the socket 3 of the measuring instrument a group to the lead of the electronic component 2.

However, it is also possible to individually raise and lower each. Further, the electronic component 2 to be measured is not limited to the one shown in FIG. 2, and it is also possible to make it possible to measure even a flat type lead 21 protruding from four directions. However, in this case, it goes without saying that it is necessary to change the shape of the holder 5 for holding the electronic component 2. Further, in the above embodiment, the magnet 55 is provided inside the jig 57 of the holder 5 as a holding means for preventing the positional deviation, but it may be built in the holder 5.

EFFECTS OF THE INVENTION As described above, according to the present invention, the electronic component is held in the holder, and the leads of the electronic component and the measuring terminals are intermittently transported by the transporting means to the corresponding positions. Since the individual electronic parts and the measuring device are electrically connected, the measurement efficiency is good, and there is no possibility of operating errors of the electronic parts as in the conventional case. Further, even if the holders are arranged in a plurality of rows, only one transportation means is required, so that the equipment cost can be reduced. Furthermore, since the leads of the electronic component are supported by the supporting portion of the holder, the leads are not damaged when they are brought into contact with the measuring terminals.

Further, since the holder is provided with the holding means for sucking and holding the package part of the electronic component, even if the carrier pallet is intermittently transported, the position of the electronic component does not shift due to the shock at the time of stop. Therefore, there is an effect that the socket and the measuring terminal can be accurately brought into contact with the lead of the electronic component, and thus various characteristics of the electronic component can be measured more reliably.
