Claims

[Claims for Utility Model Registration] 1. An XY table on which a printed wiring board is mounted is connected to an input/output part of a logic circuit section via a signal line, and transmits light to the printed wiring board according to instructions from the logic circuit section. A light irradiation mechanism emits light from diagonally above, captures the light reflected from the wiring and lands of the printed wiring board, exchanges the captured light into electrical signal data, and transmits this electrical signal data to the input/output unit. A plurality of CCD cameras with different magnifications are input to the logic circuit section through the
a CCD camera drive mechanism that switches to one of the D cameras; a CCD camera drive mechanism control circuit that is connected to the input/output section of the logic circuit section via a signal line and that controls the CCD camera drive mechanism;
a monitor connected to the input/output section of the logic circuit section via a signal line and converting and displaying the electrical signal data into an image; and an XY monitor connected to the input/output section of the logic circuit section via the signal line. A defect recognition device comprising an axis drive mechanism control circuit, and an X-axis and Y-axis drive mechanism connected to the XY-axis drive mechanism control circuit via a signal line and driving the XY table. 2. A Z-axis drive mechanism that drives the two CCD cameras in the Z-axis direction, and a Z-axis drive mechanism that is connected to the input/output section of the logic circuit section via a signal line and that controls the Z-axis drive mechanism. A claim comprising: a control circuit; and a Z-axis distance display mechanism that is connected to an input/output section of the logic circuit via a signal line and displays the depth of a defective portion of wiring on the printed wiring board. The defect recognition device according to item 1.
