ABSTRACT:
A sheet adsorption device includes a sheet adsorbing surface, a suction hole disposed on the sheet adsorbing surface, and a flow path shifting unit that shifts between a first state and a second state of a communication flow path that is communicated with the suction hole in accordance with existence of a sheet that covers the suction hole. The cross-section area of a flow path in the second state is smaller than that in the first state and the communication flow path is not closed in the second state.
