1. A sorter comprising:
a plurality of sheet output trays aligned in a predetermined direction and each capable of loading sheets thereon;
a first actuator that travels in the predetermined direction along the plurality of sheet output trays to guide a sheet onto any one of the plurality of sheet output trays;
a transferring mechanism that transfers the first actuator in the predetermined direction;
a control device that includes a processor and controls an operation of the transferring mechanism through the processor executing a control program; and
a plurality of tray full detection mechanisms provided one for each of the plurality of sheet output trays,
wherein each of the plurality of tray full detection mechanisms comprises:
a second actuator rotatable about a pivot pin in both a first rotational direction and a second rotational direction opposite to the first rotational direction; and
a tray full detection sensor that detects a fully loaded condition of the associated sheet output tray,
the second actuator comprises:
a first portion capable of abutting at a distal end thereof on an uppermost one of the sheets loaded on the associated sheet output tray;
a second portion located on a traveling path of the first actuator and disposed to fall within a predetermined detection range of the tray full detection sensor in the fully loaded condition of the associated sheet output tray; and
a connecting portion that connects between the first portion and the second portion and biases the second portion in the second rotational direction,
each of the plurality of tray full detection mechanisms further comprises:
a first stopper that restricts rotation of the first portion in the first rotational direction; and
a second stopper that restricts rotation of the first portion in the second rotational direction,
the second actuator rotates in the first rotational direction when an amount of sheets loaded on the associated sheet output tray increases or when the second portion is pushed by the first actuator,
when the second portion is pushed by the first actuator while the rotation of the first portion in the first rotational direction is stopped by the first stopper, the second portion rotates in the first rotational direction about the connecting portion,
when freed from pushing of the first actuator, the second portion is restored to an original position by biasing of the connecting portion, and
the control device identifies an actual location of the first actuator based on a change of a detection signal produced by a change in attitude of the second actuator due to transfer of the first actuator and output from the tray full detection sensor.
