Media conveying apparatus and image forming apparatus

A media conveying apparatus, comprising:

• a pair of first defining members defining an upstream part of a conveyance path in a conveyance direction;
• a pair of second defining members defining a downstream part of the conveyance path in the conveyance direction;
• a first conveyor configured to convey a medium in the upstream part defined by the pair of first defining members in the conveyance direction;
• a second conveyor configured to convey the medium in the downstream part defined by the pair of second defining members in the conveyance direction;
• a tray disposed downstream from the pair of second defining members in the conveyance direction, the tray configured to stack the medium ejected from the conveyance path;
• a first conveyance unit including a first housing that houses the pair of first defining members and the first conveyor;
• and
• a second conveyance unit including a second housing that houses the pair of second defining members and the second conveyor, the second housing having an outer wall that supports the tray,
• wherein the pair of first defining members and the pair of second defining members are movable relative to each other in the conveyance direction to lengthen and shorten the conveyance path including the upstream part and the downstream part, and
• wherein the conveyance path is shortened as the first housing enters the second housing.
