A portion H, and magnetic material leads La and Lb of different lengths arranged in the same direction at intervals smaller than the diameter from the central portion on the diameter of the bottom surface. The height is 12 mm, the length of the lead La is 30 mm, the length of the lead Lb is 25 mm, and the interval between the leads La and Lb is 2 mm on the outside. At first, the transfer of the component C has been performed by a feeding device in which only the head H is placed in an upright posture, but in recent years, the component C is placed in an upright posture, and as shown by a white arrow, for example, a longer one is used. Is required to be transferred as the front side.

(Conventional Example 1) FIG. 16 is Japanese Patent Publication No. 4-5756.
FIG. 4 is a plan view of a posture correcting apparatus 100 exemplified in “Electronic Component Posture Correcting Apparatus” according to Japanese Patent Application Publication No. 4 (JP-A) No. 4 (1999). That is,
A transportable vibration is applied to the bowl 102 of the vibrating bowl feeder 101 as a component supply device, and the stored component C is sent out on the feed truck 103. At the exit end of the feed truck 103, a parts feeding device 105 is provided. In the component feeding device 105, a feeding ring 106 called a wheel wheel is installed on a table 111 of a bowl of a vibration bowl feeder. A large number of pocket grooves 107 large enough to accommodate the head H of the component C are formed on the outer circumference of the ring 106 at a constant pitch, and are rotated clockwise as indicated by arrows when vibrating. Also, the table 111
Although not shown, a suction plate made of, for example, a magnet is embedded in the
Is retracted into the pocket groove 107, the head H is accommodated in the pocket groove 107, and the leads La and Lb are rotated and transported in a recumbent posture protruding outward in the radial direction.

[0004] While the part C is being conveyed by the feeding ring 106, a lift cam 114 is provided at a position where the shorter lead Lb does not reach and the longer lead La contacts. The longer lead La is transported on the upper surface of the lift cam 114 by the cooperative action with the holding plate 120 for preventing the part C being lifted, and the shorter lead Lb is positioned below under the influence of gravity.

However, the rolling resistance is increased. If not, the head support member may be a flat track with a locking wall for the head.

In the feeding section 70 for transferring the long lead La so as not to invert the front and back of the component C, the roots of the leads La and Lb are placed on the tip of a lead track 74 having a wedge-shaped cross section. Although the transfer is performed while being supported so as not to roll, it may be a narrow flat track that supports the leads La and Lb.

In this embodiment, the flat guide plate 6 is used in the front-rear correction section 60 to support the long lead La and the short lead Lb so that the long lead La is on the front side.
Instead of the flat guide plate 67, a vertical plate parallel to the transfer direction and having a profile of the upper end surface as viewed from the side, which is almost the same as the flat plate guide plate 67, may be used.

Further, in the present embodiment, a rubber magnet which is polarized by dispersing magnet powder in rubber as a matrix is employed in order to attract the leads La and Lb made of a magnetic material of the component C. The matrix may be plastic. Further, an electromagnet can be used instead of the rubber magnet.
