ーンテーブルの位置決め停止機構。 A printed circuit board is fixed to a work table on a turntable, and the lead wires on the four sides of each LSI package mounted on the printed circuit board are sequentially brought to a fixed position by movement by the X, Y moving mechanism and rotation of the turntable. Soldering inspection of a printed circuit board that moves and stops, and at the stopped position, irradiates a laser beam to the soldered part between the lead wire and the printed wiring of the printed circuit board to inspect the quality of the soldering. In the apparatus, positioning brackets (hereinafter simply referred to as brackets) are provided on the side surface of the turntable at positions that accurately divide the circumference into four equal parts, and the positioning brackets (hereinafter simply referred to as brackets) are installed at certain positions around the turntable while the turntable is rotating. A detector detects the bracket, and a detection signal output from the detector causes the turntable to move close to the detected bracket and press the bracket with an air cylinder to stop the turntable at a predetermined stop position. 1. A positioning and stopping mechanism for a turntable of a printed circuit board inspection device, characterized in that a stop mechanism is provided for positioning and stopping a turntable of a printed circuit board inspection device.
