Patent ID: 7363702

Claim:
A working system for a circuit substrate, comprising: a substrate conveyor which conveys the circuit substrate in a conveying direction along a straight line, and is capable of stopping the circuit substrate at a desired position in the conveying direction; a moving apparatus having a movable member which is movable in at least a direction parallel to the conveying direction of the substrate conveyor, wherein the moving apparatus is capable of moving the movable member to a desired location in the conveying direction; a working head which is held by the movable member and performs a plurality of operations for prescribed points on the circuit substrate which has been stopped at the desired position; a first detector used for decelerating the circuit substrate and a second detector used for stopping the circuit substrate, which are held by the movable member with a space therebetween in said direction parallel to the conveying direction and each of which detects a detection portion of the circuit substrate which is predetermined as an object to be detected, without contacting the detection portion; and a substrate stop position controller which controls the moving apparatus to have the first and second detectors move to respective predetermined locations, and controls the substrate conveyor such that the substrate conveyor decelerates in response to the detection of the detection portion by the first detector positioned at one of the predetermined locations and stops in response to the detection of the detection portion by the second detector positioned at the other of predetermined locations, wherein each of the first detector and the second detector outputs, when said each detector does not detect the predetermined detection portion of the circuit substrate, one of an OFF signal and an ON signal, and outputs, when said each detector detects the predetermined detection portion, an other of the OFF signal and the ON signal.
