PURPOSE:To prevent shifting in inserting order of parts previously by providing a means for detecting the condition where inserting order of parts to be inserted automatically is shifted and for stopping an automatic inserting unit in the case. CONSTITUTION:A means for detecting the condition where inserting order of parts to be inserted automatically into a printed circuit board is shifted is provided, and the means consists of a pair of photosensors 7, 8 (light projecting unit and light receiving unit). And a means for stopping an automatic inserting unit when detected signal is output by the detecting means is provided. The means is actuated when high level signal is applied to terminals 13, 14 when shift is generated in inserting order of parts. And a sensing means which informs an operator of the automatic inserting unit the condition when detection output signal of the shift detection means is output is provided. A luminous diode 20 is used for the sensing means. |
