PROBLEM TO BE SOLVED: To shorten the tact time of a surface mounting machine by controlling an overshoot amount with which a component holding tool descends beyond the position of a stop command in the component mounting head of a surface mounting machine including a landing detection sensor for detecting that a component held by the component holding tool has landed on a substrate for giving a stop command to ascending/descending means for allowing the component holding tool to ascend/descend when the landing of the component is detected by the landing detection sensor.SOLUTION: When a component is mounted, first ascending/descending means 23 is driven to allow a component holding tool 32 to descend, and when a component 60 held by the component holding tool 32 lands on a substrate 70, a stop command signal to stop the descent of the component holding tool 32 is transmitted to the first ascending/descending means 23, and an ascent command signal to allow the component holding tool 32 to ascend only by a predetermined amount is transmitted to second ascending/descending means 27.SELECTED DRAWING: Figure 6 【課題】部品保持具に保持された部品が基板に着地したことを検知する着地検知センサを備え、この着地検知センサが部品の着地を検知すると部品保持具を昇降させる昇降手段に停止指令を与える表面実装機の部品実装ヘッドにおいて、部品保持具が停止指令の位置を超えて下降するオーバーシュート量を制御して、表面実装機のタクトタイムを短縮できるようにすること。【解決手段】部品実装の際、第１昇降手段２３を駆動させて部品保持具３２を下降させ、部品保持具３２に保持された部品６０が基板７０に着地したら、第１昇降手段２３に対して部品保持具３２の下降を停止させる停止指令信号を送信するとともに、第２昇降手段２７に対して部品保持具３２を所定量だけ上昇させる上昇指令信号を送信する。【選択図】図６
