  • Patent number: 10214034
    Abstract: An inkjet recording device allows a recording medium to be set easily, and prevents the recording medium from being warped so that printing quality is not lowered. An inkjet printer includes a bed including a surface that supports a recording medium, and a pivoting device that pivots the bed around a horizontal axis to locate the bed horizontally or vertically or pivots the bed around the horizontal axis to incline the bed with respect to a horizontal plane. The inkjet printer also includes a pair of guide rails provided on the bed and extending in an X direction and a movable member extending in a Y direction, engaged with the pair of guide rails and slidable on the pair of guide rails to move in the X direction.

  • Patent number: 6229558
    Abstract: A printer has a printer body, a carriage for undergoing scanning movement over a print paper in a scanning direction, and a cassette removably connected to the printer body for storing print paper and having a code element indicative of photosensitive characteristics of the print paper. The print paper contains photosensitive microcapsules encapsulating a color developing material and a photo-curing material and has an image receiving layer for developing color by a reaction of the color developing material with the image receiving layer. The carriage has a light emitting element for emitting light of a preselected wavelength to which the photosensitive microcapsules are exposed to thereby form a latent image on the print paper. A photosensitive characteristics identifying mechanism is disposed on the carriage for reading the code element of the cassette to identify the photosensitive characteristics of the print paper.

  • Patent number: 6204914
    Abstract: A printing apparatus of a photosensitive microcapsule type comprises a chassis, a cassette for storing printing paper containing photosensitive microcapsules, a printing paper feeding device for intermittently feeding the printing paper in a feeding direction, and a printing paper pickup device for feeding the printing paper from the cassette to a preselected location from which the printing paper is intermittently fed by the printing paper feeding device. A scan shaft is mounted on the chassis for undergoing rotation about a rotational axis extending generally perpendicular to the feeding direction of the printing paper. A first spiral groove is formed in the scan shaft along a clockwise direction and has opposite ends. A second spiral groove is formed in the scan shaft along a counterclockwise direction and has opposite ends each connected to a respective end of the first spiral groove so that the first and second spiral grooves form a loop.

  • Patent number: 6021286
    Abstract: A developing portion forms a toner image, which corresponds to a recording image, with a toner which has been electrically charged to a predetermined electrical potential. A transfer portion, to which an electric potential, different from the electric potential of the toner image, is applied, transfers the toner image onto a recording medium. A first transfer-electric-potential applying portion applies a transfer electric potential to the transfer portion. A carrying portion carries the recording medium so as to cause the recording medium to pass by the transfer portion. A second transfer-electric-potential applying portion sets the recording medium and the carrying portion to cause the recording medium and the carrying portion to have a predetermined electric potential corresponding to the transfer electric potential of the transfer portion.

  • Patent number: 5946523
    Abstract: A toner developing quantity detection unit operates a plurality of electrostatic recording units to transfer Y, M, C and K color component toner marks onto a belt. A toner developing quantity correction unit detects toner developing quantities per unit area of color toners on the basis of detection signals of the color component toner marks on the belt optically detected by a sensor. The toner developing quantity correction unit corrects the toner developing quantities so as to allow the toner consuming quantities of the plurality of electrostatic recording units to be substantially the same level, on the basis of the thus detected toner developing quantities.

  • Patent number: 5724635
    Abstract: A developing device for use in an image forming apparatus, the developing device including a dispersion-preventing plate extending from an outlet of a toner hopper near to an upper portion of a stirrer, and/or a stirrer provided with blades radially fixed to its rotary axis and spiral screws alternately in the axis direction.

  • Patent number: 5582950
    Abstract: A process for producing a wherein an aminium salt infrared light absorber and a positive charge control agent are used in combination while preventing a mutual reaction therebetween. In this toner, the physical contact of the aminium salt compound with the positive charge control agent is avoided (e.g., by separately adding them to respective two separated phases of a binder resin), or alternatively use is made of such a combination of confounds as will not cause a mutual reaction (e.g., a common anion is used).
