Kind Code:
B2
Abstract:
To suppress generation of scratches and dirt on a printed face and to intend to reduce in size, a switchback device ( 1 ) provided in a conveyance path ( 12 ) for a printed medium ( 3 ), for reversing the direction of movement of the medium ( 3 ) sent from an upstream part ( 4 ) of the conveyance path ( 12 ) and then delivering the medium ( 3 ) to a downstream part ( 5 ) of the conveyance path ( 12 ), comprises a pair of operation rollers ( 15 ) including a drive roller ( 13 ) for conveying the medium ( 3 ) and a slave roller ( 14 ) cooperating with the drive roller ( 13 ) to pinch the medium ( 3 ); and a changeover mechanism ( 16 ) for changing a direction of the pair of operation rollers ( 15 ) including the drive roller ( 13 ) and the slave roller ( 14 ). The medium ( 3 ) sent from the upstream part ( 4 ) of the conveyance path ( 12 ) which is pinched by the pair of operation rollers ( 15 ) is, in this state, changed in direction as a result of a change of the direction of the pair of operation rollers ( 15 ) by the changeover mechanism ( 16 ), and then is delivered to the downstream part ( 5 ) of the conveyance path ( 12 ) by reversing rotation of the drive roller ( 13 ). Thus, generation of scratches and dirt on the printed face ( 3 a) of the medium ( 3 ) can be suppressed and the space for taking the medium ( 3 ) in upon switchback can be reduced in size.
