The second engaged section is displaced in a direction so as to be disengaged from the second engaging sections in accordance with displacement of the operation section, and the first engaged section is elastically deformed as a result of being interlocked with the second engaged section according to displacement of the operation section.

Abstract: In the application parallel processing system, on specific one of processors forming a multi-processor, an application is operated independently of other processors and on other processors, a function expansion module is operated in parallel processing under control of the application. As a result, even in such a data processing device internally provided with a processor whose processing capacity is small as a portable terminal, applications can be operated smoothly.

Abstract: A paper feeder includes: a first paper feed cassette in which to store a recording medium with a lock state; a locking portion that determines whether to bring the lock state of the first paper feed cassette into the unlocked state or the locked state; a second paper feed cassette in which to store a recording medium, capable of selectively entering an unlocked state and a locked state; and a lock state transmitting portion that transmits the lock state of the first paper feed cassette to the second paper feed cassette to bring the second paper feed cassette into the unlocked state or the locked state in accordance with the lock state of the first paper feed cassette.

Abstract: The present invention relates to a parallel processing system by an OS for single processor capable of operating an OS for single processor and an existing application on a multiprocessor and achieving parallel processing by a multiprocessor with respect to the application, wherein the multiprocessor are logically divided into two groups, i.e., a first processor side and a second processor side, and units of work that are parallelizable within the application operating on the processors on the first processor side are controlled as new units of work on the processors on the second processor side.

Abstract: An image-forming device includes an image-forming section, a separating/feeding section that separates and feeds sheets of paper from a stack into the image-forming section one sheet at a time, a pressing plate disposed on the opposite side of the stacked paper from the separating/feeding section, and a drive section that drives the pressing plate. The drive section drives the pressing plate toward the separating/feeding section when the separating/feeding section is in contact with the paper and driving of the separating/feeding section has stopped.

Abstract: A sheet feed cassette includes a case, and right and left guide members that are disposed in the case and guide edges of a sheet parallel with a sheet feeding direction. The guide members are movable in a sheet width direction in synchronization with each other. The guide members are adjusted in association with a size of the sheet to be accommodated in a sheet accommodation area. The right guide member includes a slide member and a leaf spring attached to the slide member. As the right guide member is moved toward a side wall of the case, a protrusion extending from the side wall contacts the leaf spring, through a slit formed on the slide member. The leaf spring is deformed and the sheet accommodation area in the case gradually becomes larger toward a sheet stacking direction from a bottom of the case.

Abstract: A computer-readable recording medium containing an application management program for automatically performing version management to surely manage versions of a client application that communicates with a server application. A communication request monitor acquires a communication request issued from a terminal device to a server, and extracts version information of a client application from the communication request. An upgrade determination unit determines whether the extracted version information shows the latest version, and determines that upgrade is necessary if the version is not the latest version. A setting file transmitter sends the communication request to the server if the upgrade determination unit does not determine that the upgrade is necessary. If the upgrade is necessary, on the contrary, the setting file transmitter discards the communication request and sends the client application setting file for the latest version to the terminal device sending the communication request.
