Patent ID: 8827169

Claim:
A humidity control apparatus comprising: a casing in which air enters; a plurality of humidity control chambers provided in the casing, and containing humidity controllers for controlling humidity of the air, respectively; and a damper unit capable of being installed in the casing, and removed from the casing when the damper unit is translated in a drawing direction out of the casing, wherein the damper unit includes; a plurality of dampers for opening/closing a plurality of air flow ports communicating with the humidity control chambers when the damper unit is installed in the casing, and wherein the dampers are arranged adjacent to each other and aligned in the drawing direction when the damper unit is installed in the casing; and a coupling mechanism between adjacent dampers configured to couple adjacent dampers together when the damper unit is removed from the casing in the drawing direction, and the coupling mechanism is further configured to permit uncoupling and separation of the adjacent dampers after the damper unit is removed from the casing, whereby the uncoupling of the adjacent dampers is effected by the movement of the adjacent dampers relative to each other in a direction other than the drawing direction.
