Abstract: A storage device control apparatus including first and second systematic memory module groups, each of which is composed of a plurality of memory modules, a memory controller for controlling memory access to the memory modules belonging to each of the first systematic and second systematic memory module groups. When the memory controller detects failure in one of the other memory systems, the memory system performs memory access to the memory modules belonging to its own systematic memory module groups.

Abstract: A first storage control system comprises a CHN connected to a LAN CN. The CHN comprises a NAS processor and I/O processor. The I/O processor judges whether all or a portion of block level data is to be stored in either a first storage control system or a second storage control system, on the basis of an I/O allocation control data which indicates which of either the first storage control system or the second storage control system the block level data is to be stored in. On the basis of the result of this judgment, the I/O processor transfers the block level data from the NAS processor, to at least one of the DKA and the CHF connected to the second storage control system.

Abstract: A sheet processing apparatus for an image forming apparatus is configured so as to be capable of preventing the misalignment of the end edge of sheets to be scooped and transported from an intermediate tray, and reliably preventing the so-called displacement of end edges in the post-processing steps of sheets as a recording medium with an image formed thereon, and thereby preventing the inferior appearance during binding. A sheet folding apparatus enables a user to easily adjust the misalignment of the fold line of sheets that occurs during actual use, in the middle folding processing steps of sheets as a recording medium with an image formed thereon.

Abstract: A sheet finishing apparatus includes a conveying member configured to convey recording media and a tray configured to receive the recording media conveyed by the conveying member. The tray includes a holding member configured to hold the recording media therein and to contact a first edge of the recording media such that the recording media is positioned, a rotatable moving member configured to contact the recording media such that the holding member abuts against the recording media, a discharging member configured to discharge the recording media stacked by the holding member, and a protruding member mounted on the discharging member and configured to contact a second edge of the recording media such that the recording media is positioned. One of the rotatable moving member and the protruding member positions the recording media stacked in the tray in a travel direction of the recording medium.

Abstract: A copy machine achieves a reduction in power consumption when performing a saddle-stitching operation. An image forming unit forms visible images on recording sheets in accordance with image data stored in a memory device. A post-processing unit collects the recording media on an individual copy basis to prepare a bundle of the recording sheets, and performs a saddle-stitching process and a center-folding process on the bundle of the recording sheets. The post-processing unit ejects the processed recording sheets onto a predetermined eject tray. A system control part determines whether or not a total number of the recording sheets corresponding to the image data is within a limit number for the saddle-stitching process. When the total number of the recording sheets exceeds the limit number for the saddle-stitching process, the recording sheets are ejected onto the at least one eject tray other than a predetermined eject tray.

Abstract: An I/O processor determines whether or not the amount of dirty data on a cache memory exceeds a threshold value and, if the determination is that this threshold value has been exceeded, writes a portion of the dirty data of the cache memory to a storage device. If a power source monitoring and control unit detects a voltage abnormality of the supplied power, the power monitoring and control unit maintains supply of power using power from a battery, so that a processor receives supply of power from the battery and saves the dirty data stored on the cache memory to a non-volatile memory.

Abstract: An image forming system which makes clear the point in time at which initial information transmission for all peripheral devices connected to an image forming apparatus serving as the main device is complete, even when the peripheral devices are attached in various combinations, to thereby reduce the time until it is possible for a user to start operation to the lowest level possible, and to reduce waiting time for powering on. The image forming system such as a copying machine includes at least one peripheral device which can be serially connected to a main body of the copying machine, and communication means for performing communication with the most upstream peripheral device of the peripheral devices. When turned on or reset, the image forming system displays functions of the peripheral devices on an operating unit based on initial information delivered from the peripheral devices.

Abstract: A sheet folding device for folding a sheet or a sheet stack conveyed thereto of the present invention includes a path along which the sheet or the sheet stack to be folded is conveyed. A fold plate is movable in a direction perpendicular to the above path for forming a fold in the sheet or the sheet stack. A pair of rotatable fold rollers face the fold plate and are positioned one above the other. Pressing members exerts, when the fold is to be formed, a pair of equal pressing forces on the fold rollers to thereby maintain the nip between the fold rollers on a line including the locus of movement of the fold plate.

On the basis of the result of this judgment, the I/O processor transfers the block level data from the NAS processor, to at least one of the DKA and the CHF connected to the second storage control system.

Abstract: A sheet finisher for executing preselected processing with a sheet conveyed thereto of the present invention includes a first processing tray configured to temporarily store the sheet and deliver it. A first and a second path are positioned downstream of the first processing tray in a direction of sheet conveyance and configured to convey a first and a second sheet stack, respectively. The first path conveys the first sheet stack upward over the downstream portion of the first processing tray while the second path conveys it downward over the same. A switching device selects either one of the first and second paths. The sheet finisher of the present invention is low cost and highly productive and space saving.
