  • Publication number: 20100262598
    Abstract: A search rule generation unit (2502) pregenerates a search rule for searching for a search target part among parts forming a user interface, based on user interface information indicating the parts forming the user interface and the positional relationship between the parts, search target part information indicating the search target part among the parts, and structure definition information defining the structure of the user interface. When new user interface information is input, a part search unit (2503) searches for the search target part among parts indicated by the new user interface information by using the pregenerated search rule. This makes it possible to correctly specify a part in a user interface having an unclear inconstant structure.

  • Patent number: 7676185
    Abstract: A toner container of the present invention includes a cylindrical portion containing toner used in an electrophotographic type complex machine. When the cylindrical portion is driven to rotate, the toner gets out via an outlet thereof. The cylindrical portion of the toner container has an inner wall provided with a coat layer containing fluorine-containing silica fine particles, which are obtained by modifying a property of the surfaces of silica fine particles by using a fluorine-based silane coupling agent. This coat layer effectively prevents the toner from being adhered to the inner wall of the toner container.

  • Publication number: 20090162107
    Abstract: A toner cartridge has a toner storage chamber, a discharge outlet, a conveying screw, and a blocking wall. The discharge outlet serves to send out toner stored in the toner storage chamber, and the conveying screw serves to convey the toner stored in the toner storage chamber. Further, before the toner cartridge mounted into an image forming apparatus, the blocking wall is located in a space between a toner area, which is an area in the toner storage chamber where the toner exists, and the discharge outlet, thereby putting the space in a blocked state. The toner cartridge further includes a driving mechanism for, when the toner cartridge has been mounted into the image forming apparatus, driving the conveying screw by power transmitted from the image forming apparatus, so as to cancel the blocked state.
