Part mounting apparatus with single viewing camera viewing part from different directions

A part mounting apparatus comprising:

• a part holding/transfer means for picking up a part at a part supply position and movable in at least a Z direction among mutually perpendicular X, Y and Z directions for transferring the picked up part to a predetermined part mounting position for mounting;
• a single viewing and recognizing means having a optical viewing axis in the Z direction for viewing and recognizing an image of a shape and position of a part held by said part holding/transfer means and mounted on said apparatus so as at the most, to be movable in the direction of said optical viewing axis;
• an inclined mirror means having a mirror surface inclined to a plane defined by said X and Y directions for reflecting a further image of the shape of a part held by said part holding/transfer means which further image is the image of the part perpendicular to the direction of the optical axis of said viewing and recognizing means;
• and
• means for moving said part holder/transfer means and said inclined mirror means relative to each other at least in the Z direction for positioning a part held thereby relative to said inclined mirror means for causing the mirror means to reflect the further image of the part into said single viewing and recognizing means, whereby the single viewing and recognizing means can simultaneously view and recognize the image of the part being held by said part holding/transfer means taken from two mutually perpendicular directions.
