- the compression coil spring 248 is disposed between the head of the bolt, which is the first regulating member 247, and the first bus bar 242. Since the first regulating member 247 is fixed to the second bus bar 244, the compression coil spring 248 urges the first bus bar 242 against the second bus bar 244.

- the second regulating member 241 is a member for regulating the movement of the first bus bar 242 in the first direction.
- the proximal and distal restricting members 241a and 241b are formed of leaf springs. Under normal conditions when no external force is applied, the proximal and distal restricting members 241a and 241b are in the movement path of the first bus bar 242 in the first direction and come into contact with the first bus bar 242 to restrict its movement. On the other hand, when an external force is applied and the proximal and distal restricting members 241a and 241b are pressed in the direction of the second bus bar 244, they are configured to move out of the movement path of the first bus bar 242 in the first direction and release the restriction on the movement of the first bus bar 242.
- FIG. 16 shows the state in which the arm 292 grips the first bus bar 242.
- the distal pressing member 294 of the arm 292 presses the distal restricting member 241b, thereby releasing the restriction on movement of the first bus bar 242 in a direction away from the central opening 234a.
- the gripping portion 295 of the arm 292 fits into the gripping hole 242a of the first bus bar 242. This allows the first driving member 298 of the position adjustment mechanism 290 to move the first bus bar 242 in a direction away from the central opening 234a.
- the jig distal pressing member 284 has the same function as the above-mentioned distal pressing member 294. That is, the jig distal pressing member 284 is a member for pressing the distal restricting member 241b to release the restriction on the movement of the first bus bar 242.
- FIG. 20 shows the state before the first claw member 282 is fitted into the gap between the first bus bar 242 and the second bus bar 244.
- FIG. 21 shows the state after the first claw member 282 has been fitted into the gap between the first bus bar 242 and the second bus bar 244.
- FIG. 22 shows the state after the second claw member 283 has been fitted into the gap between the first bus bar 242 and the second bus bar 244.
- the first claw member 282 and the second claw member 283 are configured to slightly lift the first bus bar 242 from the second bus bar 244 when fitted into the gap between the first bus bar 242 and the second bus bar 244. That is, the position adjustment jig 280 of this embodiment is designed to bias the first bus bar 242 toward the second bus bar 244 by the above-mentioned compression coil spring 248. As shown in FIG. 23, the first bus bar 242 is slightly lifted from the second bus bar 244 by the first claw member 282 and the second claw member 283, so that the movement of the first bus bar 242 relative to the second bus bar 244 can be made smooth. It is noted that the first claw member 282 and the second claw member 283 do not have to be provided. In particular, if a disc spring 249 is used instead of the compression coil spring 248, the first claw member 282 and the second claw member 283 do not need to be provided.

- the substrate mounting method grips the first bus bar 242 using the arm 292 and moves the first bus bar 242 (step S105). For example, step S105 moves the first bus bar 242 to a position closest to the central opening 234a or to a position farthest from the central opening 234a depending on the specifications of the power supply position of the substrate WF.
- the substrate mounting method then retracts the arm 292 from between the base plate 220 and the face plate 230 (step S106).
- the substrate mounting method involves placing the substrate WF on the upper surface of the base plate 220 (step S107).

- the present application discloses, as one embodiment, a substrate holder in which the first busbar has a long hole that is longer in the first direction than the extension direction of the first busbar, and the second busbar has a first restricting member disposed at a position corresponding to the long hole, the first restricting member having a proximal end that contacts the edge of the long hole when the first busbar moves in a direction away from the central opening, and a distal end that contacts the edge of the long hole when the first busbar moves in a direction toward the central opening.
- the present application discloses a plating apparatus in which the position adjustment mechanism includes an arm for gripping the first bus bar, a first drive member for moving the arm in a first direction toward and away from the central opening, and a second drive member for moving the arm in a second direction perpendicular to the extension direction of the first bus bar and the first direction.
