Document Type and Number:
Japanese Patent JP2016023057
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an image forming device which detects that sheets moved from accommodation parts are exposed from an opening part by using a small number of sensors which is smaller than the number of the accommodation parts, and a sheet accommodation device.SOLUTION: This image forming device has detection means. The detection means includes a rotating body which contacts with a sheet, and rotates accompanied by the movement of the sheet, and a signal output part which outputs a signal corresponding to the rotation of the rotating body. The detection means detects whether or not the sheet is in an exposed state on the basis of the signal which is outputted from the signal output part. When a first sheet accommodated in a first accommodation part and a second sheet accommodated in a second accommodation part are stacked on each other, and exposed from the opening part, sheet moving means moves the first sheet and the second sheet to the opening part so that the rotating body contacts with the second sheet and rotates after the rotating body contacts with the first sheet and rotates.SELECTED DRAWING: Figure 11
