Abstract: A sheet processing apparatus includes: a staple tray on which sheets are stacked temporarily and stapled after being aligned together and from which the stapled sheets are discharged to a discharge tray; a discharger to discharge the sheets to the staple tray; a rear end reference against which rear ends of the sheets are abutted to be aligned together; a returner to return the sheets discharged by the discharger and to align the sheets together in a conveying direction based on the rear end reference fence; a lifter to lift and lower the returner with respect to a sheet; and a guide configured to guide the sheets toward the rear end reference fence when the sheets are returned and to be lifted and lowered in synchronization with the lifting and lowering by the lifter.

Abstract: When a sheet processing device is in operation, if any of a paper jam, a motor error, and an open door occur, a sheet-processing-device control unit stops all the loads of the sheet processing device other than the entrance motor. After that, the sheet-processing-device control unit determines whether an entrance sensor detects a sheet remaining in a sheet discharging path. If no sheet is detected, the entrance motor stops in the same manner as the other loads stop. If the entrance sensor detects a sheet, the entrance motor continues driving. When the number of steps of the entrance motor that continues driving increases to a number equal to or more than a predetermined number that corresponds to a sheet position that is accessible by a user from a discharge tray, the entrance motor stops.

Abstract: When a sheet is conveyed to a position where a conveying speed can be changed from a first conveying speed to a second conveying speed while a discharging unit is discharging a preceding stack of sheets, a conveyance control unit calculates a third conveying speed for conveying the sheet based on a first conveyance time to be taken until a leading end of the stack of sheets reaches a second tray unit from a first tray unit and a second conveyance time to be taken until a current discharging operation is completed from a start of the current discharging operation, and changes the conveying speed from the first conveying speed to the third conveying speed.

Abstract: Provided are an authentication method, authentication system and a terminal device in which the authentication of a non-participating third node is can be simplified and can be executed in the case of multicast by using an authentication ticket in a distributed processing network system, the non-participating third node being intended to access each of the nodes, including a first and a second node, constituting a workgroup. The first node that has already participated in the workgroup authenticates the third node intended to participate in the workgroup and issues the authentication ticket including the signatures of both nodes, and when the authentication ticket is submitted to the second node, the second node permits the third node to access, without password-based-authentication, by authenticating the first node and the second node which have signed the authentication ticket.

Based on these feature amounts, an attribute to be used for correction is decided. Then, an attribute different from the decided attribute between the attribute of the first region and the attribute of the second region is changed to the decided attribute.

Abstract: A personal computer is operable to sectionalize a document image to form a plurality of image areas each having an attribute associated with a compression mode. Then, it is determined whether the image areas overlap with one another to form an overlap area. When the overlap area is formed, the overlap area is separated from the engaged image areas. If one of the engaged image areas is included within the remaining image areas, an attribute for the overlap area is set up according to the inclusive relationship of the engaged image areas. If there is not such an inclusive relationship, the attribute in the overlap area is set up according to the occupancy rate of the overlap area to each of the engaged image areas, and weighting coefficients of the respective attributes of the engaged image areas.
