Patent ID: 8578595

Claim:
An operation performing apparatus configured to perform an operation to a surface of a circuit substrate, the surface having a fiducial mark, the apparatus comprising: an operation performing head which is configured to perform the operation to the circuit substrate; a substrate feeding device having an upstream side configured to accept the circuit substrate and a downstream side configured to accept the circuit substrate from the upstream side, and defining a feeding direction, the substrate feeding device being configured to stop the circuit substrate at a predetermined operation position; a head moving device which includes: an X-direction moving device which includes a head supporting member having a lower portion to which the operation performing head is attached, and is configured to move the head supporting member in an X-direction parallel to the feeding direction; and a Y-direction moving device which is configured to move the X-direction moving device in a Y-direction perpendicular to the X-direction, wherein the head moving device moves the operation performing head on a plane parallel to the circuit substrate; and an image taking device which is configured to take an image of the fiducial mark affixed to the surface of the circuit substrate and which is supported by the head supporting member such that the image taking device is located below the X-direction moving device, at an aligned position which is aligned, in the Y-direction perpendicular to the feeding direction, with the operation performing head attached to the head supporting member.
