Claims

[Scope of Claim for Utility Model Registration] A device in which a unit is housed so that it can be pulled out, and the unit side contactor and the board-side conductor are brought into contact with and separated from each other by moving along the direction of the pull-out, wherein the unit of the board-side conductor a shielding plate that covers the joint with the side contact;
and a rotating arm that moves in a direction substantially parallel to the panel-side conductor; a guide portion that extends in the unit pull-out direction;
a drive shaft for rotating the rotating arm; provided on the unit, the shielding plate engages with a guide portion provided on the drive shaft, and moves the shielding plate in the pulling direction and insertion direction of the unit to a closed position covering the joint portion; A closed switchboard with a shutter device, comprising: a drive unit for driving a drive shaft to position the drive shaft in both the open position and the open position removed from the drive shaft;
