1. A laminating device, comprising:
a plurality of laminating heads that each hold a unit laminated body in which a separator and an electrode plate are laminated;
a drum section that holds a plurality of the laminating heads arranged on a circumference thereof;
a drum drive unit that rotates the drum section to advance each laminating head to a laminating position that faces a lamination stage; and
a plurality of head drive units that move the respective laminating heads independently of the move thereof made by the rotation of the drum section, wherein
a head drive unit for a laminating head that has reached the laminating position drives the laminating head such as to offset the advancement of the laminating head made by the rotation of the drum section,
each laminating head discharges, onto the lamination stage, a unit laminated body that the laminating head has been holding, so that a plurality of unit laminated bodies are laminated,
the drum section includes a discoid flange portion that projects perpendicularly to a rotating shaft of the drum section, and
the head drive unit includes i) a bracket that supports the laminating heads and that is engaged with the flange portion and ii) a motor supported by the bracket, the head drive unit moving on a circumference of the flange portion when the motor is driven.
