<P>PROBLEM TO BE SOLVED: To provide a substrate conveying apparatus that is disposed downstream of a device for inspecting a substrate of an electric part, has versatility owing to its applicability to various conveying paths, and is capable of preventing a substrate from falling or being pinched between devices. <P>SOLUTION: The independent substrate conveying apparatus 1 is disposed downstream of the device for inspecting a substrate 2 of an electric part. It comprises a main conveyor 3, a sub conveyor 4, a switching means 5 for changing positions of both conveyors, a safety check sensor for determining whether the substrate 2 exists on a boundary between adjacent devices, and a control device. When the safety check sensor detects that the substrate 2 exists on a boundary between adjacent devices, the control device performs control to prohibit the conveyor switching means 5 from changing the positions of the main conveyor 3 and sub conveyor 4. <P>COPYRIGHT: (C)2008,JPO&INPIT |
