Abstract
A remaining sheet volume detecting apparatus includes a loading unit that loads a sheet; a moving unit that moves the loading unit to a feed position of the loaded sheet; a feeding unit that feeds the sheet from the loading unit; a sheet thickness detecting unit that detects a thickness of the sheet; a load thickness detecting unit that detects that thickness of the loaded sheet within the loading unit, gradually decreasing; and a remaining sheet volume calculating unit that calculates a remaining volume within the loading unit based on the certain load thickness detected by the load thickness detecting unit and the sheet thickness detected by the sheet thickness detecting unit, each time a sheet is fed by the feeding unit after the load thickness detecting unit detects that the thickness of the loaded sheet within the loading unit has reached the certain load thickness.
