Medium accumulating device with accumulation table detector

摘要

A medium accumulating device has an accumulation table on which a medium is accumulated, an elastic member that supports the accumulation table, and an accumulation table detector that detects lowering of the accumulation table. The accumulation table is sensed to determine whether the accumulation table lowers below a predetermined position to thereby determine whether or not a medium is accumulated on the accumulation table.

主权项

1. A medium accumulating device comprising:
an accumulation table for accumulating media; an accumulation table detector detecting a lowering of said accumulation table, said accumulation table detector detecting whether or not said accumulation table lowers below a predetermined position in an upper part of a lifting and lowering range of the accumulation table; and a medium detector detecting whether or not at least one medium of the media is accumulated on said accumulation table when said accumulation table is located above the predetermined position, said accumulation table detector including a first set that includes a light-emitter and an optical sensor that form a first optical path in a direction intersecting a lifting and lowering direction of said accumulation table, said medium detector including a second set that includes a light-emitter and an optical sensor that form a second optical path in the direction intersecting the lifting and lowering direction of said accumulation table.
