  In the electronic component supply apparatus of the collective exchange cart system, when the parts feeder is a tape feeder, a supply reel wound with an electronic component storage tape (hereinafter simply referred to as a tape) is disposed on the base of the cart. As the supply reel, there is a type that does not have a rotating shaft at the center, but is simply placed on a receiving body such as a receiving rod, and a type that is pivotally attached to the central shaft portion and rotates around the shaft portion. There are things.

  The former type has a simple structure and is low in cost, but does not have a shaft portion, so that the supply reel is poorly rotated when feeding out the tape, and in the case of a large-diameter supply reel, it is formed of cardboard. For this reason, there is a drawback in that the edge portion that hits the receiver is easily deformed, and the rotational property is worsened.

  On the other hand, since the latter type has a shaft portion, there is an advantage that the tape can be fed out by the stable rotation of the supply reel. However, when exchanging the supply reel due to, for example, out-of-stock electronic components, the supply reel must be removed from the shaft and a new supply reel must be mounted on the shaft. However, since the supply reels are juxtaposed at a low position near the floor at a narrow pitch, it is difficult for the operator to replace the supply reels.
