Abstract: The present invention provides an information processing device for estimating usage of contents and properly limiting functions realized through use of the contents in accordance with the estimation. Usage of contents is estimated by determining in which of cache memory means and content storage means the contents are stored. When the contents are processed or executed, it is determined whether to limit functions realized through processing or execution of the contents, on the basis of the estimated usage of the contents and function limit information showing a rule regarding limits on functions realized through processing or execution. On the basis of the determination, the functions realized through processing or execution of the contents are limited.

Abstract: The present invention provides a means for reflecting modifications made in a server to data with regard to a scope of rights, which are granted to an application program operable in a communication device such as a mobile station, on data stored in the communication device. To achieve the aim, in a system according to the present invention, Java-AP software is provided to a mobile station by transmitting an ADF, a SDF and a JAR file from servers to the mobile station in that order. The SDF is a file containing data indicating restrictions of behavior of a Java-AP in a mobile station. The SDF also contains data indicating a validity state of the SDF, namely ‘valid’ or ‘invalid’, which is managed by management server device 18. Before a mobile station runs a Java-APP which is installed in the mobile station, the mobile station accesses management server device 18 and checks whether a SDF corresponding to the Java-APP is valid.

Abstract: The present invention provides a method for making it more convenient for a user to try out contents. When contents are received, the contents are written in a free space or a space where some data is already stored, of cache memory means. When contents are written in the cache memory means, the contents are processed or executed. When a command is issued using operation means for storing contents processed or executed, the contents are read from the cache memory means, and written in content storage means.

A native mailer obtains an e-mail, and stores in a folder for an application mailer, an e-mail generated by using an application mailer.

Abstract: A driving mechanism for use in an image forming apparatus has a rotary shaft, a driving joint, a drum gear, a cleaning roller gear, and a transfer roller gear. The rotary shaft extends through a photosensitive member along an axis of rotation of the photosensitive member. The rotary shaft is rotatably supported at the opposite axial end parts thereof by bearings, respectively. The rotary shaft is un-rotatably jointed to the photosensitive member relative thereto at a lateral side part of a rear end part of the rotary shaft corresponding to the rear side of the image forming apparatus. The driving joint is jointed to the rear end part of the rotary shaft protruding from the photosensitive member at the rear side of the image forming apparatus to input a rotating force of a drum motor to the photosensitive drum. The drum gear is provided at the rear side of the photosensitive member. The cleaning roller gear and the transfer roller gear are in mesh with the drum gear.

Abstract: A cleaning device of an image forming machine including a pair of arm members each having one end portion pivotable about a support shaft, a cleaning roller rotatably supported between front end portions of the arm members via a shaft, helical compression springs for urging the arm members so as to bring the cleaning roller into contact under pressure with the surface of a photoconductor drum, a drive gear of the photoconductor drum, and a driven gear of the cleaning roller in mesh with the drive gear. Each of the arm members is disposed axially outwardly of the photoconductor drum. The center of the support shaft of each of the arm members is either placed on an extension of a line of action passing the point of engagement between the drive gear and the driven gear, or placed on an extension of a straight line passing the point of engagement, the straight line being within an angular range of some angle to the line of action.

Abstract: A cleaning device including a housing disposed above a photoconductor drum and having an opening portion open downward toward the circumferential surface of the photoconductor drum, a cleaning blade disposed in the housing so as to be located in the opening portion downstream in the direction of rotation of the photoconductor drum, and a cleaning roller disposed in the housing so as to be located in the opening portion upstream from the cleaning blade in the direction of rotation of the photoconductor drum; and an image forming apparatus equipped with the cleaning device. In the housing of the cleaning device, a spiral roller for letting out a toner recovered into the housing is disposed above the cleaning blade. A partition wall is disposed between the cleaning blade and the spiral roller, and a toner movement space for moving the toner recovered into the housing is formed between the front end of the partition wall and the circumferential surface of the cleaning roller.

Abstract: A casing unitarily housing the photosensitive drum and developing device of a xerographic imaging system such that the thus composed imaging unit is retained in a predetermined operational position removably installed into a printing machine. The casing is configured such that when the imaging unit is removed from the printing machine, the imaging unit is retained in a posture equivalent to the predetermined operational orientation. Toner and developing agents are thus held in a steady state within the imaging unit, which particularly is an imaging unit in a lateral-transfer, vertical sheet-transport xerographic printing machine.

Abstract: An image forming machine, including an image bearing member, a developing unit for developing a latent electrostatic image on the image bearing member into a toner image, a cleaning unit for removing remaining toner from the image bearing member after transfer of the toner image from the image bearing member onto a sheet member, and a toner supply unit for supplying toner to the developing unit. The toner supply unit includes a first toner acceptance region where fresh toner is introduced, a second toner acceptance region where recycled toner, that has been removed from the image bearing member by the cleaning unit, is introduced, a toner discharge region having a toner discharge opening communicating with the developing unit, a first toner conveying member for conveying fresh toner from the first toner acceptance region to the toner discharge region, and a second toner conveying member for conveying recycled toner from the second toner acceptance region to the toner discharge region.

Abstract: A cleaner for cleaning the nozzle portion of a powder filling apparatus for filling a container with powder by equally evacuating the inside and the outside of the container, and dropping powder through the nozzle portion into the container simultaneously with raising the pressure outside the container is provided. The cleaner includes a cleaning head having a cleaning chamber therein for enclosing the nozzle portion airtightly when the cleaning head is fitted to the nozzle portion; a gas passage disposed in the cleaner head for allowing compressed air to flow therethrough so as to spurt the compressed air to the nozzle portion; and an exhaust passage for allowing powder flowing down in the cleaning chamber together with the compressed air spurted to the nozzle portion to be discharged together with the compressed air.
