PROBLEM TO BE SOLVED: To allow landing of each holder of a component holding head including a plurality of holders for holding a component, to be detected by one detecting means.SOLUTION: A component holding head of a surface mounting machine includes a plurality of spindles 31 and one pressing tool 25 for lowering the spindles 31 in a Z direction along an axial direction, and a holder 32 for holding a component is attached to a lower end of each of the plurality of spindles 31 via an elastic body 34, and the plurality of spindles 31 are moved relatively to the pressing tool 25 to select a spindle 31a to be lowered, and the pressing tool 25 is lowered to lower the spindle. A non-contact sensor 40 which detects the change in position relative to the spindle 31a of the holder 32 in a vertical direction, which is caused when the holder 32 at the lower end of the spindle 31a lands due to lowering of the spindle 31a to compress the elastic body 34, without contacting to generate a landing detection signal is provided integrally with the pressing tool 25. 【課題】部品を保持する保持具を複数備えた部品保持ヘッドにおいて、各保持具の着地を一つの検知手段によって検知できるようにすること。【解決手段】複数本のスピンドル３１と、これらのスピンドル３１を軸線方向に沿ったＺ方向に下降させる１個の押圧具２５と備え、複数本のスピンドル３１の下端には部品を保持する保持具３２が弾性体３４を介して装着され、押圧具２５に対して複数本のスピンドル３１を相対的に移動させることにより下降させるスピンドル３１ａを選択し、押圧具２５を下降させることにより当該スピンドルを下降させる表面実装機の部品保持ヘッドにおいて、スピンドル３１ａの下降によりその下端の保持具３２が着地し弾性体３４が圧縮されて当該保持具の当該スピンドルに対する上下方向の位置が変化したことを非接触式で検知して着地検知信号を発する非接触センサ４０を、押圧具２５と一体的に設けた。【選択図】図２
