Medium transport apparatus, medium processing apparatus, and recording apparatus

A medium transport apparatus comprising:

• a first route member disposed so as to face a first surface of a medium;
• a second route member disposed so as to face a second surface of the medium, the second surface being opposite to the first surface, both the first route member and the second route member constituting a medium transport route therebetween;
• a transport roller pair that nips and feeds the medium being transported between the first route member and the second route member, the transport roller pair including a first roller that comes into contact with the first surface of the medium and a second roller that comes into contact with the second surface of the medium;
• and
• a gate that is switchable between a first state and a second state, the first state being a state in which the gate closes the medium transport route at a location upstream, in a medium transport direction, of a nip location at which the transport roller pair nips the medium, the second state being a state in which the gate opens the medium transport route, wherein
• the gate is disposed on a rotating member, the rotating member being rotatable around a first rotating shaft, the first rotating shaft being a rotating shaft for the first roller,
• the first rotating shaft engages with a fixed member,
• both the first route member and the second route member are fixed to the fixed member, and
• both the first route member and the second route member are fixed to the fixed member by inserting a screw in a direction along a straight line that passes through a rotational center of the first roller and a rotational center of the second roller as seen from a rotating shaft direction of the first roller or the second roller.
