A transfer mechanism for moving container between over/under, entrance/exit gravity rollerway conveyors also holds the containers at a position for user interface in removing articles from or inserting articles into the container. The power operated scissors mechanism moves the carriage vertically between the conveyors, while a first piston-cylinder tilts the carriage at an angle to match an aligned conveyor with respect to a first axis and a second piston-cylinder tilts the carriage about a second orthogonally arranged axis to determine an appropriate user interface tilt. An automatic control, in response to a single input command from the user, cycles the carriage for unloading a container, loading a new container, and placing the new container at a predetermined user position. Additional user commands can override the predetermined user position to adjust the tilt and height of the carriage for the user, which adjustment may be temporary or stored as a new predetermined user position.
