Is set (S220). Next, the CPU 32 determines whether or not the offset value has already been specified for the set component P based on the stored contents of the offset information 35 (S230). When the offset value has been specified, the CPU 32 omits the offset setting process and executes the process after S310. The operator may specify an offset value when there is a part P having a low sampling rate empirically. In this case, the CPU 32 gives priority to the specified offset value.

In this process, the CPU 32 moves the measuring unit 25 above the component P and causes the measuring unit 25 to measure the distance to the upper surface of the component P (see FIG. 2). Using this measurement result, the CPU 32 can obtain the height H of the upper surface of the component P and obtain the difference value from the reference height Hb. Next, the CPU 32 examines whether the dimensional accuracy of the type of the holding member 16 in which the height-measured component P is held is low or high based on the offset information 35 (S250). Examples of the type of the holding member 16 having high dimensional accuracy include a paper member and the like. Further, as a type of the holding member 16 having low dimensional accuracy, for example, an embossed resin member or the like can be mentioned.

- the second offset range F2 is set in a range between the upper limit value Fa2 and the lower limit value Fb2. Further, the second offset range F2 is set to a narrower range than the first offset range F1 (for example, +0.1 mm to ⁇ 0.2 mm with respect to the reference height Hb).
- the absolute value of the upper limit value Fa2 is equal to or less than the absolute value of the upper limit value Fa1, and the absolute value of the lower limit value Fb2 is set to be smaller than the absolute value of the lower limit value Fb1. Since the height of the component P held by the holding member 16b having high dimensional accuracy has a correspondingly smaller clearance deviation width, a smaller offset range can be set.

- the measuring unit 25 is made to measure the top surface height H of the component P on the holding member 16, and the measured top surface height H of the component P is set.
- the offset value for adjusting the sampling height of the mounting unit 20 by the elevating mechanism 24 is set accordingly.
- the control unit 31 does not execute the measurement and the offset value setting by the measuring unit 25. By limiting the processing, the control unit 31 can further improve the efficiency of the processing.
