Moving device and electronic component mounting apparatus

A moving device for moving a mounting head which holds and mounts electronic components onto a board, comprising:

• a first beam which extends in a first direction;
• a slider provided on the first beam so as to be movable in the first direction;
• a first drive unit for driving movement of the slider along the first direction;
• a mounting head which is fixed to the slider so as to be movable integrally with the slider and which has a plurality of nozzles for holding the electronic components, the nozzles being arrayed in the first direction;
• an image pickup device, which is fixed to the slider so as to be movable integrally with the slider, for picking up an image of a mounting position for the electronic components on the board;
• a second beam for supporting the first beam so that the first beam is movable in a second direction orthogonal to the first direction;
• and
• a second drive unit for driving movement of the first beam along the second direction, wherein
• the image pickup device is placed at such a position as to be contained within a width of an array of the nozzles in the first direction and moreover contained within a total width of the mounting head and the first beam in the second direction.
