Electronic Component Mounting Apparatus and Printed Circuit Board Processing Apparatus

摘要

An electronic component mounting apparatus or a printed board processing apparatus is provided which can reliably detect positioning of a board in a position for having a component mounted thereon and further detect transferring of the board to a predetermined position, thereby contributing toward productivity improvement. To detect transferring of a board, light is transmitted from a light transmitting section to hit an end portion of the board. To detect positioning of the board, a light receiving section is optically blocked by the board.
