摘要:
A data processing device comprises a storage unit adapted to store an initial value of a pair of a public key and a private key and a communication unit adapted to execute communication with an external device with use of the initial value of the pair of the public key and the private key stored in the storage unit, thereby enabling encryption communication without generating the pair of the public key and the private key.

A double-surface printing apparatus, which is small-sized and has a simple construction to make it impossible to take out a sheet, of which one surface has been subjected to printing, from outside. The apparatus includes a paper discharge tray, to which sheets having been subjected to printing are discharged; a sheet reversing mechanism including a reversal/temporary storage unit for guiding a sheet in a direction different from a discharge direction toward the paper discharge tray, once exposing the sheet outside of the apparatus, and rotating conveying rollers in an opposite direction to thereby reverse the sheet; and a protective cover, which covers the sheet conveyed to the reversal/temporary storage unit so that a sheet, of which one-surface has been subjected to printing, cannot be taken out from outside.

With an information processing apparatus, if a user operates a “back” button of a web browser while a job is being executed, a script for controlling the job currently being executed is lost, and the job can no longer be controlled. An information processing apparatus of the present invention can communicate with a web server, and includes a web browser that displays an operation screen provided by the web server. This information processing apparatus manages the status of a job to be executed, and restricts acceptance of an instruction for screen transition from the user according to the managed status of the job while the job instructed by the web server is being executed.

In a device information management system in which a management server for managing device information and various devices are connected, a plurality of different types of device information is transmitted to the management server at predetermined timings, respectively. In a device information management system in which a management server for managing device information and various devices are connected, a request to transmit the device information to the management server is transmitted to another device and the device information of the requesting device is transmitted to the management server in accordance with the request.

The present invention provides a print system having an enhanced operability for printing document information transmitted/received through a network. In this system, documents stored in a database are searched for so as to obtain a search result, and a user specifies a document to be printed from among documents indicated by the search result in a browser screen. Accordingly, a printer extracts information about a storage location of the document and downloads the information of the document stored in a document server thereto.
摘要:
In an image processing method for performing image processing by causing a plurality of image processing apparatuses including a first image processing apparatus and a second image processing apparatus to work in cooperation, an image processing apparatus that issues a job sends an announcement notice informing that the job will be sent to image processing apparatuses designated to perform image processing in cooperation. When excluding the first image processing apparatus designated as a cooperative device from cooperation, an instruction to abort transition of the job is sent to the first image processing apparatus based on the announcement notice. Alternatively, an instruction to abort transition of the job is sent to the second image processing apparatus that transitions the job to the first image processing apparatus.
摘要:
The rotating speed of a photosensitive body is reduced for preventing deterioration thereof due to ozone in an electrophotographic device which comprises the photosensitive body, a charger which uniformly charges the surface of the photosensitive body, and a motor control unit which performs drive control for a motor which drives the photosensitive body. The motor control unit provides a plurality of speed levels including a first speed level for rotating the photosensitive body during printing and another speed level for rotating the photosensitive body at a reduced speed lower than the speed used during printing. The speed is changed-over between the plurality of speed levels depending on the operating condition. Thereby, deterioration of the photosensitive body due to ozone generated from the charger is prevented, and additional deterioration of the photosensitive body due to rotation thereof other than during a printing operation is also prevented.
摘要:
In an image processing method in which a plurality of image processing apparatuses perform image processing in cooperation with each other, an image processing apparatus that issues a job sends an announcement notice informing that the job will be sent to image processing apparatuses designated to perform image processing in cooperation. When an image processing apparatus that has received the announcement notice receives a request to display job status from a user, it requests other image processing apparatuses that work in cooperation for job status information based on the announcement notice. Upon receiving responses to the request, the image processing apparatus notifies a user of the job status information.
摘要:
An image processing apparatus which makes it possible to realize easy accessing of registered information of any function and provide a user interface having high operability. The image processing apparatus stores setting information configured via an operating section and access information for use in accessing the setting information in association with each other. Further, the image processing apparatus stores the setting information and button information in association with each other. The button information is displayed on a touch panel in a user selectable form. When an item of the button information displayed on the touch panel is selected by a user, a portal application detects the access information associated with the selected button information item. The setting information is acquired based on the detected access information. The image processing apparatus performs image processing based on the acquired setting information.
