1. A medium conveyance device comprising:
a branching portion where a conveyance path of a medium branches into a first conveyance path and a second conveyance path;
a path switching member that is a member provided in the branching portion and rotates to switch between a first state where a moving direction of the medium is set to the first conveyance path and a second state where the moving direction of the medium is set to the second conveyance path;
a solenoid that rotates the path switching member by a plunger configured to be displaced in a suction direction and a return direction opposite to the suction direction; and
a link member that is a member provided in the path switching member and engages with the plunger,
wherein the link member includes a groove portion,
the plunger includes a pin member that moves in the groove portion in association with the displacement operation,
the solenoid regulates, in a suction state, a posture of the path switching member in the second state,
a contact surface that is an inner surface of the groove portion and with which the pin member comes into contact when the plunger moves in the suction direction is formed in a non-linear shape to have a first region and a second region, the first region being a region extending in a first direction away from the center of rotation of the path switching member, and the second region being a region extending in a second direction away from the center of rotation and intersecting the first direction, and
an angle formed by the suction direction and the second direction is smaller than an angle formed by the suction direction and the first direction.
