Title:
SHEET STACKING DEVICE
Document Type and Number:
Japanese Patent JP2015209315
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sheet stacking device which is capable of appropriately stopping discharge operation of sheets into a stacking tray depending on a state of sheets to be discharged when a full-state detection signal is generated.SOLUTION: When an amount of sheets which have been sequentially discharged from an image forming apparatus reaches a full capacity of a stacking tray 19, a full-state detection sensor S2 outputs a detection signal by a rocking movement of a detection lever 41. A control part selects and executes one of a first stop operation control of stopping driving of a discharge roller pair 18 after the generation of the detection signal has continued for a fixed period of time and a second stop operation control of stopping driving of the discharge roller pair 18 immediately upon the generation of the detection signal. If the generation of the detection signal does not continue for the fixed period of time when executing the first stop operation control, the control part determines that the detection signal has been erroneously generated.
