<p>PURPOSE:To prevent the erroneous display which accelerates a user to supply paper sheets in spite of the existence of paper sheets by installing a judgement processing intercepting means for intercepting the judgement processing in a paper existence judging means during the time when revolution operation signals are outputted. CONSTITUTION:During the turning operation of a paper tray 3, even if the signal level supplied from a paper existence sensor 35 changes to the paperless state judgement level by the vibration caused by the mechanical operation, a paper existence judging means 44 does not output the result of the paperless state judgement. Accordingly, the generation of the trouble that the erroneous display for a user to accelerate to supply paper sheets in spite of the existence of paper sheets is prevented.</p> |
