An information processor includes a rotating magnetic disk that stores therein data, an accessing unit that accesses the magnetic disk, a detecting unit that detects an abnormal state. The abnormal state is a state that a user takes an action that may cause the magnetic disk to vibrate. The information processor further includes a control unit that terminates an access to the magnetic disk and stops rotation of the magnetic disk when the detecting unit detects the abnormal state, and an output unit that outputs a request for the action after the control unit has stopped the access and the rotation.

Information processor and image generator for stopping rotation of a magnetic disk in response to an abnormal state

An image processing apparatus includes an extracting unit to extract watermark data from image data of an image; a generating unit to generate a watermark image based on the watermark data; and a superimposing unit to superimpose the watermark image on the image.

Image processing apparatus, image processing method, and computer product

A method of controlling an energy saving mode in an image forming apparatus having hardware resources used in an image forming process and programs for performing the image forming process includes a step of letting the image forming apparatus enter into an energy saving mode in a standby state in which the image forming apparatus is not used, and a step of recovering at least part of functions of the image forming apparatus in response to setting of a data carrier in the image forming apparatus, said data carrier being in a possession of an operator.

Image forming apparatus and method of controlling energy saving mode

In a data transmission apparatus and method of the present invention, a specific operator ID for an operator who uses a data processing device to process image data to be copied or transmitted, is selected. Specific owner IDs for owners who are authorized to access the image data, are selected. User identification data, inclusive of all operator IDs and owner IDs correlated to the data processing device, are stored in a storage device each time image data is captured by the data processing device. Allocation of the stored user identification data to each of the image data is managed by reading items of the user identification data from the storage device in response to the selections of the specific operator ID and the specific owner IDs and displaying the user identification data items.

Data transmission apparatus and method for management of user identification data allocated to image data

In a filing system, a data processing apparatus is connected to a file server via a transmission path. Image data of a document is captured into the data processing apparatus. The captured image data is stored onto an image storage medium. A plurality of owner identifications are acquired when the image data is captured. The owner identifications are correlated with the image data stored on the image storage medium, and the stored image data is allowed to be accessed when any of the owner identifications correlated with the image data is verified. The image data is output in a readable manner by retrieving the stored image data of the image storage medium when the access to the image data is allowed.

Filing system which provides increased availability of image data stored therein

An image reading apparatus includes a reading part reading original, a time measuring part being able to measure different times selectively, and a defining part determining separation of sheets of the original read by the reading part. The time measuring part selects a time to be measured according to a predetermined condition, and the defining part determines the separation of sheets of the original when the selected time has elapsed without an operation concerning a subsequent reading operation being performed after a reading operation of the reading part is stopped.

Various devices of the apparatus including the photoconductive drum and developing roller are separated into an upper and a lower unit which are openable away from each other. A photoconductive drum assembly including the photoconductive element and a developing assembly including the developing roller are individually detachable from a body of the apparatus. Various measures are taken to enhance stable and safe operation, miniaturization, easy maintenance, operability, service life, and image quality.

Electrostatic recording apparatus

An electrostatic printing apparatus capable of printing both normal sheets of paper and composites such as envelopes. In accordance with a mode in which normal sheets are printed and with the other mode in which envelopes are printed, transfer current applied to a transfer charger, fixing pressure applied to between a pair of fixing rollers, and heat generation of the heat source(s) in the fixing roller(s) can be changed respectively to those suitable for the sort of a transfer member. This change can be performed manually, or controlled automatically based on a signal issued from a member sorting sensor disposed in a paper supply portion.
