Abstract: There is provided an inkjet recording apparatus having a cleaning device, which can securely remove ink on a conveying belt having no negative effects on conveyance accuracy. The inkjet recording apparatus for forming an image on a recording medium includes a conveying belt for supporting and conveying a recording medium, a recording head for forming an image by jetting ink onto the recording medium conveyed by the conveying belts, and a cleaning device having a cleaning roller provided in pressure-contact with the conveying belt and driven to rotate in the same direction as the conveying direction of the conveying belt, wherein, the cleaning roller is set to rotate at a surface linear speed thereof lower than a conveying speed of the conveying belt.

Abstract: An image recording apparatus for recording an image on a recording medium includes a conveying belt for supporting and conveying the recording medium, and a recording head for recording the image by jetting ink onto the recording medium. The apparatus further includes a plurality of cleaning rollers for cleaning the conveying belt, the cleaning rollers being in pressure-contact with the conveying belt, and a plurality of cleaning liquid baths for respectively storing cleaning liquid to be used to remove dirt deposited on the respective cleaning rollers and for dipping the respective cleaning rollers into the cleaning liquid. The apparatus uses liquid waste as cleaning liquid in a cleaning liquid bath on an upstream side of the conveying belt, the liquid waste having become unable to be used in a cleaning liquid bath on a downstream side of the conveying belt any longer as cleaning liquid.

Abstract: An optical transmission and receiving equipment to comprises an optical source emitting a laser beam; a optical receiving instrument for receiving that laser beam; an optical filter established between that optical source and optical receiving instrument; a rotary mechanism to change the tilt angle of the optical filter in relation to the laser beam; and a tilt angle controlling instrument for controlling the movement of the rotary mechanism. The tilt angle controlling instrument varies the tilt angle of the optical filter within a prescribed period. Therefore, in the aforementioned optical transmission and receiving equipment P, the transmittance of the laser beam L1 passing through the interference filter 2 is automatically controlled to become the maximum by the control signal based on the received light intensity signal S0 of the optical receiving instrument 3.

Abstract: The color image forming machine such like a color printer or a color copier for forming a color image on a recording sheet. The image forming machine includes a photoreceptor belt; a belt driver for rotating the photoreceptor in a longitudinal direction; a laser beam scanner for repeatedly scanning the photoreceptor in a direction perpendicular to the longitudinal direction, with the laser beam, so that the latent image is formed on the photoreceptor; a developer for developing the latent image with plural color toners; a measuring unit for determining a rotation time of the photoreceptor; and a controller unit for controlling a scanning frequency of the laser beam scanner so that one scanning time of the laser beam scanner is set to the result of dividing the rotation time of the photoreceptor, while the photoreceptor rotates one round, by an integer.

Abstract: An automatic focusing camera having a driving mechanism for moving a taking lens on the basis of a signal provided by a distance measuring device. The lens position is controlling by a cam member capable of being turned stepwise in one direction about the optical axis of a taking lens by a pulse signal given by the distance measuring device. The driving mechanism has a light quantity controlling movable coil member and a taking lens driving and controlling movable coil member. Both the light quantity controlling movable coil member and the taking lens driving and controlling movable coil member are disposed within a gap and exposed to a common magnetic field.

Abstract: An electromagnetically driven shutter device in which a first coil drives shutter blades to control an aperture and shutter time. A second coil controls the moving distance, that is maximum aperture, of the first coil by being located at a plurality of positions including its initial position.

Abstract: An automatic focusing camera comprising: a distance measuring means, a cylindrical permanent magnet means which is provided fixedly inside of the lens barrel, a cylindrical moving coil member which is concentric with said cylindrical permanent means, a lens unit which is driven together with the cylindrical moving coil member, and a spring for urging said lens unit to the most frequently employed focusing point of its travelling range, wherein the lens unit is adapted to move to a point corresponding to an output signal from the distance measuring means under the influence of the cylindrical moving coil member.

Abstract: The invention describes a taking lens driving system using permanent magnets provided inside of the lens barrel. A plurality of movable coils surrond the circumference of the taking lens and are arranged so as to transverse the magnetic flux of the permanent magnets.At least one of the movable coil members drives the taking lens unit, while the other coils are used to the range of movement of the movable coil member.
