When a shutter button of a digital camera is pressed, a picture signal fetched from a CCD is converted to a digital signal and compressed and written into a nonvolatile memory means like a flash memory card as a picture file which can be identified uniquely. A user can produce a control file for controlling print processing, display processing, transmission processing and the like for the picture file by selecting a particular picture file using an operation key. If multi-screen print is carried out on a printer unit, a vertical direction of each picture is unified. Further, upon reprint operation for multiple order persons, sorting work after the print is facilitated by providing with an identification means for identifying each order person.

A file management method for reducing a seek operation to a minimum even when a UDF file system is used is provided. The file management method has file management information for managing contiguous blocks on a disc as an extent and for grouping the extent as a file and managing the file, and includes the steps of: when creating a new directory on the disc, reserving as a reserved area for recording file management information on the file a file or a data area in the directory; and reserving a directory block having a predetermined size in the reserved area for recording a file entry of the directory and a file identifier descriptor of the directory.

An electrophotographic toner is formed as a blend of toner particles and external additives. The external additives include (1) first inorganic fine particles having an average primary particle size of 80-800 nm of oxide of a metal selected from the group consisting of titanium, aluminum, zinc and zirconium, (2) second inorganic fine particles other than silica having an average primary particle size of below 80 nm and (3) silica fine particles having an average primary particle size of below 30 nm. As a result, the toner can be made free from difficulties, such as melt-sticking onto an image-bearing member in a low humidity environment, roughening of halftone images in a low humidity environment, toner blot-down after storage at high temperatures or in continuous image formation on a large number of sheets, fog in continuous formations of images of low color area percentage in a low humidity environment, and re-transfer in multi-color image formation. Thus, the toner is suitably used in a multi-color image forming system.

Provided is an inkjet recording medium in which hydrated alumina and a sulfinic acid compound or thiosulfonic acid compound coexist in a pigment in an ink receiving layer, and which can prevent white-background yellowing during storage in a resin file holder or the like and ensure printing quality at the same time. The ink receiving layer of the inkjet recording medium contains the sulfinic acid compound or thiosulfonic acid compound, which functions to prevent yellowing, in a salt form or in a free form so as to be diffusible.

A data processor transfers a data stream, which is stored on a storage medium, to a connected device. The data stream includes attribute information that specifies the format of the data stream. The data processor includes: an interface section, which communicates with the device to acquire format information about a format that is compatible with the device; a reading section for reading the attribute information and the data stream from the storage medium; a reading control section for determining, by the attribute information and the format information, whether or not the format of the data stream needs to be converted; and a converting section for outputting the data stream either after having converted the format of the data stream into the one specified by the format information or without converting the format of the data stream as determined by the reading control section. The interface section transmits the data stream, which has been output from the converting section, to the device.

A speaker apparatus includes an elliptical-shaped or a round-edged rectangular-shaped vibration plate; an edge damper portion disposed on an outer peripheral edge portion of the vibration plate; a recessed portion formed between said vibration plate and said edge damper portion, having a caliber of a shape corresponding to the shape of said vibration plate; and an air core voice coil fitted into an interior of said recessed portion. The speaker apparatus further includes a frame for mounting said edge damper portion to support said vibration plate, having a stepped portion and a vertical wall portion; and an edge damper frame arranged on an outer periphery of said edge damper portion, having a support portion placed on the stepped portion and a rising portion being in contact with the vertical wall portion.

A toner is comprised of a binder resin, a colorant and a wax. The binder resin has a polycarbonate resin in an amount of from 0.1% by weight to 50.0% by weight and a resin other than the polycarbonate resin in an amount of from 50.0% by weight to 99.9% by weight, based on the weight of the binder resin. In molecular weight distribution as measured by gel permeation chromatography of tetrahydrofuran-soluble matter, the toner contains in an amount of 15.0% by weight or less based on the weight of the toner a component which has in its structure a repeating unit of the polycarbonate resin and is contained in components having a molecular weight of 1,000 or less.

摘要:
A data processor in which special regions 31a, 31b are set in the backmost screen, and comprises means for specifying the functions to be started corresponding to them, and means for registering the specified special regions 31a, 31b and the function to be started corresponding to them in correspondence to a specific wallpaper 31. When coordinates data of the position selected by the cursor in the backmost screen is included in the special regions 31a, 31b, the function registered in correspondence thereto is started. In such constitution, complicated operation for starting up a required function by accurately selecting a small icon by the cursor is eliminated, and the working efficiency and controllability are enhanced.
