And a required number of solenoid valves located in the middle of each individual pipeline.

According to this configuration, only one joint is required to be provided for the mounting machine body and the collective exchange cart to supply pressurized air to the tape feeder on the batch exchange cart. Piping can be simplified. However, in general, it is necessary to equip a required number of solenoid valves to each of a plurality of batch exchange carts prepared for exchange for one mounting machine. Further, for controlling each solenoid valve, it is necessary to arrange a large number of connection terminals at an electrical connection portion between the mounting machine main body side and the collective exchange carriage side, which complicates electric wiring.

On the other hand, according to the structure of the illustrated embodiment, the solenoid valve may be provided only on the mounting machine body side.
Further, since the electric wiring for each solenoid valve only needs to be on the mounting machine main body side, the electric connection portion and the electric wiring between the mounting machine main body side and the collective exchange cart side are simplified.
