78, bolts E1 and E2 extend in the width direction of movable element 36, penetrate through pivoting member 82, and are screwed into widthwise movable member 80, and bolts F1 and F2 extend in the approaching and separating direction, penetrate through pivoting member 82, and are screwed into vertically movable member 84. The state where the bolt is tightened and the two members cannot move relative to each other is referred to as a fixed state.

Bolts D1 and D2 are loosened in a state where pivoting member 82 is fixed to widthwise movable member 80 by bolts E1 and E2 and vertically movable member 84 is fixed to pivoting member 82 by bolts F1 and F2. Widthwise movable member 80, pivoting member 82, vertically movable member 84, and movable element 36 are integrally movable in the width direction of moveable element 36. Since widthwise movable member 80 and holding body main body 78 are provided with gap R11 therebetween in the x direction, widthwise movable member 80 is caused to move in the x direction with respect to holding body main body 78.

By moving widthwise movable member 80 and the like in the width direction of movable element 36 along the upper surface of holding body main body 78, the position of movable element 36 in the width direction is adjusted, and bolts D1 and D2 are tightened. The position of movable element 36 in the width direction can be adjusted within the range of the gap between bolts D1 and D2 and the through hole of widthwise movable member 80. The operation of bolt D2 is performed using through hole 86 formed in vertically movable member 84 and penetrating in the vertical direction. The jig is passed via through hole 86 and engaged with the head of bolt D2 to loosen or tighten bolt D2.

Bolts F1 and F2 are loosened, in a state where widthwise movable member 80 is fixed to holding body main body 78 by bolts D1 and D2, and pivoting member 82 is fixed to widthwise movable member 80 by bolts E1 and E2. Accordingly, vertically movable member 84 and movable element 36 are movable in the vertical direction with respect to widthwise movable member 80 and pivoting member 82. The vertical movement of vertically movable member 84 is allowed by gap R12 in the vertical direction between vertically movable member 84, widthwise movable member 80, and pivoting member 82. In addition, as illustrated in FIG. 5, since step surface 84a of vertically movable member 84 and inner side surface 80a of widthwise movable member 80 abut on each other, the movement of vertically movable member 84 in the x direction is restricted.

Vertically movable member 84 and the like are moved in the vertical direction along widthwise movable member 80 and the height which is the position of movable element 36 in the vertical direction is adjusted to tighten bolts F1 and F2. The position of movable element 36 in the vertical direction can be adjusted within the range of the gap between bolts F1 and F2 and the through hole of pivoting member 82.

Bolts E1 and E2 are loosened in a state where widthwise movable member 80 is fixed to holding body main body 78 by bolts D1 and D2 and vertically movable member 84 is fixed to pivoting member 82 by bolts F1 and F2. Accordingly, pivoting member 82, vertically movable member 84, and movable element 36 are pivotable around axis X with respect to widthwise movable member 80. The pivoting of pivoting member 82 around axis X is allowed by gap R13 between pivoting member 82 and holding body main body 78 in the vertical direction, gap R12 between pivoting member 82 and widthwise movable member 80 in the vertical direction, and the like. In addition, since inner side surface 82a of pivoting member 82 and outer side surface 80b of widthwise movable member 80 abut on each other, the movement of pivoting member 82 in the x direction is restricted.

When pivoting member 82 (and vertically movable member 84 and movable element 36) is pivoted around axis X, the inclination of movable element 36 around the X axis is adjusted to tighten bolts E1 and E2. Accordingly, the inclination of movable element 36 around the X axis can be adjusted.

Although movable element 36 is fixed to vertically movable member 84 by bolt N, as illustrated in FIGS. 2 and 4, protruding portion 36s provided on a side surface of movable element 36 and extending in the vertical direction is fitted into recessed portion 84r provided on vertically movable member 84 and extending in the vertical direction. Therefore, in a state where bolt N is loosened, movable element 36 can move in the vertical direction relative to vertically movable member 84. The position of movable element 36 in the vertical direction can also be adjusted by moving movable element 36 in the vertical direction with respect to vertically movable member 84.

For example, in a state where movable element 36 enters groove section 46 of loading stand 32, these operations can be performed by an operator by measuring the gaps between movable element 36 and groove section 46 using a jig such as a dial gauge and a strain gauge so as to reduce the gaps.

In the present example, widthwise movable member 80, pivoting member 82, vertically movable member 84, bolt N, bolts D1 and D2, bolts E1 and E2, bolts F1 and F2, protruding portion 36s provided on movable element 36, recessed portion 84r provided on vertically movable member 84, and the like constitute adjustment mechanism 88.

The mounter includes control device 200. As illustrated in FIG. 10, control device 200 includes controller 202 mainly including a computer, and multiple drive circuits 204. Each of circuit board conveyance and holding device 4, component supply device 6, and head moving device 8 is connected to controller 202 via drive circuit 204, and solenoid valve devices 74 and 76 of loading stand moving device 40 and movable element moving device 41 are connected to controller 202. In addition, camera 20, electrical characteristics measuring section 42, display 216, loading stand position sensor 218, movable element position sensor 220, and the like are connected. Solenoid valve devices 74 and 76 are controlled based on output signals of loading stand position sensor 218 and movable element position sensor 220, and the like. In addition, the measurement result of the electrical characteristic of component s can be displayed on display 216.

In measuring device 22 configured as described above, an operation in a case where the electrical characteristic of component s is measured will be described. Measuring device
