Abstract: An image forming apparatus includes a document-image forming section, a code-image forming section and an acquisition section. The document-image forming section forms a document image on a medium. The code-image forming section forms on the medium a code image containing position information, which is used to specify a position on a surface of the medium. The acquisition section acquires a position shift amount between the document image and the code image, which are formed on the medium.

Abstract: An electronic document management system includes an acquisition unit, a specifying unit and a database. A medium includes a document image and a plurality of code image two-dimensionally arranged. Each code image includes position information and medium identification information. The acquisition unit acquires a code image corresponding to an operation position on the medium in conjunction with a user's operation with respect to the medium. The specifying unit specifies the medium identification information included in the code image acquired by the acquisition unit. The database stores personal information associated with the medium identification information specified by the specifying unit.

Abstract: An image processing apparatus includes a document image generating section, a medium ID generating section, a correspondence information storing section and an image output section. A document image generating section generates a document image based on a managed data in the apparatus. A medium ID generating section generates a medium ID for identifying a medium on which the document image is printed. A correspondence information storing section stores correspondence information by which the managed data and the medium ID are correlated with each other. An image output section outputs an image in which a code image indicating the medium ID is superimposed on the document image.

Abstract: Provided is an inkjet recording device that has a conveying unit for conveying a recording medium, plural recording head groups each structured by plural unit heads disposed along the conveying direction, and an ink receiving unit for receiving ink discharged from the unit heads. The recording head groups, correspond respectively to plural individual recording regions which are sectioned off in the recording medium transverse direction which is orthogonal to the conveying direction, are disposed so as to be at respectively different positions at adjacent individual recording regions along the conveying direction. The ink receiving unit is disposed so as to face ink drop discharging surfaces of the unit heads. The conveying unit is plural conveying belts disposed at positions evading trajectories of the ink drops from the unit heads as seen in a direction of a line normal to the recording medium so as to be divided in the conveying direction.

Abstract: A driving apparatus transmits a driving force from a drive source to a driven body via a multiple-stage gear train (including, for example, gears). In the multiple-stage gear train, the speed fluctuation phase of a mesh frequency occurring at each mesh point of the gear train including the gears to a target gear is set in a range in which the speed fluctuation amplitude of the target gear positioned downstream at the third stage or later is equal to or less than the speed fluctuation amplitude of the immediately preceding mesh gear positioned upstream. The invention also applies to an image formation apparatus using the drive as a drive of a driven body.

Abstract: An image-forming apparatus adjusts the running state of a belt by displacing one of the rolls supporting an endless belt, wherein the roll is displaced to prevent the belt from being twisted by a change in the tension of the endless belt that stems from the operation for displacing the roll. When the image-forming apparatus is provided with a belt running adjusting mechanism 20 which adjusts the running state of the endless belt 21 by displacing one (drive roll 22) of plural rolls supporting the belt 21 in the adjusting directions J, K, there is provided a tension correction mechanism 60 which corrects a change in the tension of the endless belt 21 that is caused by the operation of the belt running adjusting mechanism 20 for displacing the roll 22, by displacing, in the correction directions L, M, a contact member (tension roll 25) which is in contact with the belt 21 along the direction of width thereof.
