Abstract: An electronic component mounting system formed by interlinking a plurality of electronic component mounting machines in series for enabling a machine operator to be prevented from mistaking the machine to which an operation section or a signal tower belongs for another. In each of the machines, an operation section placed to one direction side from a center in the board conveying direction of the machine on a machine side face is placed in an attitude in which the normal direction of an operation face is inclined toward the center line. A signal tower placed on one direction side from the center line on the top face of the machine is placed in an attitude in which at least one portion is inclined only at an angle ? toward the center line.

Abstract: An object of the invention is to provide an electronic component mounting system formed by interlinking a plurality of electronic component mounting machines in series for enabling a machine operator to be prevented from mistaking the machine to which an operation section or a signal tower belongs for another. In each of machines M1 to M5 making up an electronic component mounting system formed by interlinking a plurality of machines in series, an operation section 4 placed to one direction side from a center in the board conveying direction of the machine on a machine side face MS is placed in an attitude in which the normal direction of an operation face 4a is inclined toward the center line CL side. A signal tower 22 placed to one direction side from a center line CL on the top face of the machine is placed in an attitude in which at least one portion is inclined only at an angle ? toward the center line CL side.
