Electric component mounting apparatus

A component mounting apparatus which comprises:

• at least first and second component supply assemblies each including a plurality of juxtaposed component supply units:
• at least first and second movable tables for supporting thereof the respective first and second component supply assemblies, each of said first and second movable tables being movable in a direction parallel to the direction in which the component supply units of the associated component mounting assembly are juxtaposed:
• a common track along which any one of the first and second movable tables is moved:
• a positioning means for positioning a support member on which components are desired to be mounted;
• a component mounting means for receiving a component at a predetermined position of the component supply assembly and mounting the component onto the support member;
• and
• a table moving means selectively connectable with one of the first and second movable tables for driving the movable table along the common track, said table moving means comprising a fixed shaft member disposed laterally of and extending parallel to the common track, a drive means mounted on the fixed shaft member for movement therealong between opposite ends of the fixed shaft member, and a releasable coupling means for selectively connecting and disconnecting the drive means with and from any one of the movable tables, respectively.
