  • Publication number: 20140065547
    Abstract: An apparatus includes: an image sensor including pixels which constitute rows; and a controller configured to control an irradiation operation of irradiating a pixel of the image sensor with a charged particle beam to generate a signal charge, a transfer operation of sequentially transferring, pixel by pixel in a column direction, the signal charge accumulated in the irradiated pixel, and an output operation of outputting the transferred signal charge from the image sensor. The controller is configured to cause a first irradiation operation for a first part of the rows as an irradiated region, a transfer operation of transferring a signal charge generated in the first part to a second part of the rows adjacent to the first part, as a non-irradiated region, and a second irradiation operation for the first part, to be performed sequentially.

  • Publication number: 20140003829
    Abstract: The image forming apparatus can switch between a color mode, in which an image is formed by sequentially transferring the color toner images formed by developing members in an overlapping manner, and a mono mode, in which an image is formed by using one developing member. The developing member used in the mono mode develops the toner image to be transferred secondly or thereafter in the color mode, the exposure device exposes a non-image portion where the toner image is not formed on the surface of the image carrier at an exposure amount smaller than an exposure amount for an image portion where the toner image is formed, and, in the mono mode, the exposure amount at which the exposure device exposes the non-image portion of the image carrier in the case the image is formed in the mono mode is smaller than the color mode.

  • Publication number: 20130307041
    Abstract: Before transmitting a print job to a printing apparatus, a CPU of a print processing apparatus determines whether paper information designated in the print job has been registered in a paper information database of the print processing apparatus. If the paper information has not been registered, the CPU extracts paper information similar to the paper information designated in the print job from those stored in the paper information database of the print processing apparatus. Furthermore, the CPU copies information about the dependency on the printing apparatus, which is included in the extracted paper information (printer dependency information) to the paper information designated in the print job. Then, the CPU registers the paper information designated in the print job, to which the printer dependency information has been copied, in a paper information database of the printing apparatus and transmits the print job to the printing apparatus.

  • Publication number: 20130299714
    Abstract: A charged-particle beam lens includes a plate-like anode, a plate-like cathode, and an insulator disposed between the anode and the cathode. The insulator, the anode, and the cathode have a passage portion through which a charged beam is passed. A high-resistance film is formed on an inner side of the insulator, the inner side forming the passage portion, or an outermost side of insulator, and the anode and the cathode are electrically connected together via the high-resistance film. The anode and the high-resistance film, and the cathode and the high-resistance film each contain the same metal or semiconductor element and have different resistant values. This suppresses electric field concentration due to an increase in resistance and poor connection at the interface between the anode and the cathode and the high-resistance film or at the interface between the electroconductive film and the high-resistance film, thus suppressing generation of discharge.
