| 20100019442 | Sheet processing apparatus, sheet processing method, and image forming apparatus - 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. | 01-28-2010 |
| 20100237556 | Sheet stacker and image forming apparatus - A sheet processing apparatus includes a fixed tray and a movable tray. The fixed tray is fixed at its downstream portion in a sheet transport direction and includes a sheet loading surface. A downstream portion of the sheet loading surface of the fixed tray is positioned at a higher level than an upstream portion thereof. The movable tray is pivotally supported, at its upstream portion, by a pivot support provided on the fixed tray. An angle between a sheet loading surface of the movable tray and a horizontal direction is more gentle than an angle between the sheet loading surface of the fixed tray and the horizontal direction. | 09-23-2010 |
| 20110064427 | Sheet processing device, image forming system, and sheet conveying method - 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. | 03-17-2011 |
| 20110074081 | Sheet processing apparatus and image forming apparatus - 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. | 03-31-2011 |
| 20110091260 | Paper processing apparatus and image forming apparatus - A paper processing apparatus includes: a discharging unit that discharges the paper onto a staple tray; a paper returning unit that reverses the paper discharged by the discharging unit and performs alignment in a conveying direction by abutting the paper against a rear end reference fence; a supporting unit that supports the discharging unit in a state capable of coming in contact with or separating from the paper; a contact and separation unit by which the discharging unit comes in contact with or separates from the paper; and a pressurizing unit that is moved by the contact and separation unit, does not load the discharging unit in a standby state where the discharging unit is held apart from the paper, and applies contact pressure in a state where the discharging unit is in contact with the paper. | 04-21-2011 |

| 20090210719 | COMMUNICATION CONTROL METHOD OF DETERMINING WHETHER COMMUNICATION IS PERMITTED/NOT PERMITTED, AND COMPUTER-READABLE RECORDING MEDIUM RECORDING COMMUNICATION CONTROL PROGRAM - In a first information processing device, a specific part of a binary code of a first application program developed in a first memory and a specific function are used to calculate a first identification value. The first identification value is transmitted from the first information processing device to a second information processing device. In the second information processing device, a specific part of a binary code of a second application program developed in a second memory and a specific function are used to calculate a second identification value, and the first identification value received from the first information processing device is compared with the second identification value. If these identification values are identical, connection with the first information processing device is permitted in the second information processing device. | 08-20-2009 |
| 20090271630 | AUTHENTICATION SYSTEM, AUTHENTICATION METHOD AND TERMINAL DEVICE - 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. | 10-29-2009 |
| 20100225947 | IMAGE FORMING SYSTEM, IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - The image forming system includes an image forming apparatus; a detection apparatus that detects a user who enters or exits a room where the image forming apparatus exists; and an administration server that judges a security level of the room based on a detection result drawn by the detection apparatus. The image forming apparatus selects a print mode based on the security level judged by the administration server and performs printing by the selected print mode. | 09-09-2010 |
| 20110038002 | IMAGE FORMING DEVICE, INFORMATION PROCESSING DEVICE, AND PRINT PREVIEW PROCESSING METHOD - An image forming device is capable of making data communication with at least one printing device through a network. The image forming device comprises: a print job acquiring part for acquiring a print job created in response to user's instructions for printing; an image forming part for producing a printed output by executing the print job; an event detecting part for detecting occurrence of an event; and a print preview processing part for acquiring a first print preview image showing a printed output to be produced when the print job is executed in the image forming part, and a second print preview image showing a printed output to be produced when the print job is executed in the at least one printing device, and for outputting the first and second print preview images. The print preview processing part acquires and outputs the first and second print preview images when the event detecting part detects occurrence of the event. | 02-17-2011 |
| 20110063673 | APPARATUS AND METHOD FOR OUTPUTTING IMAGE, AND COMPUTER-READABLE STORAGE MEDUIM FOR COMPUTER PROGRAM - An apparatus for outputting an image is provided. The apparatus includes a detection portion that detects a state of electronic paper placed on a predetermined location, and a transmission portion that sends, to the electronic paper, image data for displaying an image depending on the state of the electronic paper. | 03-17-2011 |
