<P>PROBLEM TO BE SOLVED: To improve operability and also prevent any operation errors by causing a detector for detecting an extraction of a sheet object to automatically disables detectors that detect a human body, when the sheet object is extracted from a sheet stacking device. <P>SOLUTION: A third extraction portion 40 able to extract paper 3, stacked on a pallet 15 on a paper stacking board 11, from a sheet stacking section 4, is provided with three first detectors 40A, 40B, and 40C for detecting a human body. A pair of distance sensors 49A and 49B detect movement of a paper 3 in a width direction and downstream movement of the paper 3 in a paper conveyance direction. When detection sensors C3, C3', and a light-off button 47 are turned on, the detection of the first detectors 40A, 40B, and 40C are disabled. Their disabled detection states are held by the pair of distance sensors 49A and 49B detecting the downstream movement of a paper 3 in the paper conveyance direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
