Abstract:
An image recording apparatus for forming a latent image on a photosensitive pressure sensitive sheet and for developing the latent image on a developer sheet. The apparatus includes an exposure unit and a developing unit positioned close to each other. The apparatus also includes an optical system for irradiating light onto an original and directing the light reflected at the original toward the exposure zone. The original has an original image facing downwardly, and the photosensitive sheet has an imaging surface facing downwardly at the exposure zone. The optical system provides a U or J-shaped optical path extending from the original to the exposure zone. The optical system has reflection mirror unit vertically movably secured to a pair of frames of the apparatus. The frames are reinforced with a partition member which also functions as a light shielding member. The partition member divide an internal space defined by the frames into two chambers so as to accommodate therein the developing unit and the optical system, respectively.
Abstract:
In a color picture image recording apparatus using a photosensitive and pressure-sensitive recording sheet having on its surface pressure rupturable microcapsules each containing a photosensitive material and a chromogenic material selected from cyan, magenta and yellow, and a mechanical strength of the microcapsule varies when exposed, a color tone of a reproduced picture image can easily be adjusted by the provision of a filter unit. The filter unit is used in conjunction with a radiation unit which radiates onto the photosensitive and pressure-sensitive recording sheet a light carrying a color image of an original to form a latent image, and includes filters each selectively passing a light of a particular wavelength which causes to vary the mechanical strength of one of the cyan-, magneta-and yellow-containing microcapsules. Each of the filters is movably disposed on a light path so as to change its filtering characteristic, whereby when the photosensitive and pressure-sensitive recording sheet is pressure-developed, the color tone of the reproduced color image can be adjusted.
Abstract:
If the user specifies a color mode, an image reader previously moves a read head to a position where a first read target position r and a read start position on an original are identical with each other. If the user specifies a monochrome mode, the image reader previously moves the read head to a position where a second read target position and the read start position on an original are identical with each other. After this, an image can be read from the same range without increasing the time required for image read processing.

Abstract:
A document feeder including a document feed unit that feeds a document along a document feed path extending from a document loading section to a document output section via a scanning position. The document feed unit includes a first feed roller pair nipping and feed a document opposed to the scanning position at a position downstream in a feed direction from the scanning position, and a second feed roller pair nipping and feed the document fed by the first feed roller pair at a document feed speed higher than that of the first feed roller pair at a position downstream in the feed direction from the first feed roller pair.
Abstract:
An image reading device has a CIS unit. The CIS unit is held by a carriage. A compression coil spring that presses the CIS unit toward a contact glass plate is disposed between the bottom surface of the carriage and the bottom surface of the CIS unit. An extension coil spring that pulls the CIS unit toward the carriage is attached between the bottom surface of the carriage and the center portion of the CIS unit.

An image reading apparatus, including a transparent plate, a positioning member which is provided on the transparent plate so as to define, on one of opposite sides of the positioning member, a reading place where a sheet having an image is placed, and which positions the sheet placed on the reading place, an image taking device, a housing which supports the transparent plate and accommodates the image taking device such that the image taking device is movable below, and along, the transparent plate, and a reading control portion which controls the image taking device to take, through the transparent plate, the image from the sheet placed on the reading place, while the image taking device is moved below, and along, the transparent plate. The positioning member is detachably attached to the housing.
Abstract:
An image reading apparatus including a housing; an image taking device which is provided in the housing; a power producing device which is provided in the housing and which produces a power to move the image taking device; a first reading control portion which controls the power producing device to move the image taking device relative to a first sheet placed on a first reading place, so that the image taking device takes the first image from the first sheet; a second-sheet feeding device at least a portion of which is provided right above the second reading place and which feeds a second sheet to a second reading place; and a second reading control portion which controls, in a state in which the image taking device is positioned at a position right below the second reading place, the second-sheet feeding device to feed the second sheet to the second reading place, and controls, when the second sheet is fed through the second reading place, the image taking device to take the second image from the second sheet. The power producing device is provided, in a portion of the housing that is different from a portion thereof located right below the first reading place, at a position assuring that a projection of at least a portion of the power producing device in a direction parallel to a direction in which the image taking device is moved is formed on the image taking device.
Abstract:
An image recording apparatus employs a transfer type recording medium which includes a photosensitive pressure-sensitive recording sheet and a developer sheet. The former sheet is exposed to light to form a latent image corresponding to an image of an original. This sheet is exposed to light while being transported at a speed equal to or in the case of making a copy of enlarged or reduced size, at a speed different from a speed at which the original is scanned by light. The photosensitive pressure-sensitive recording sheet on which the latent image is formed is brought into facial contact with the developer sheet and the latent image is developed under pressure to provide a visible image on the developer sheet. This developing operation is performed while moving the superposed two sheets at the same speed as the speed when the latent image is formed on the photosensitive pressure-sensitive recording sheet. Since both the exposure and developing operations can be performed substantially simultaneously, the copying speed is increased. Further, no receiving unit needs to be provided in a position between the exposure unit and the developing unit, which may otherwise be needed for receiving the exposed recording sheet if development is performed upon completion of the exposure. Thus, the overall apparatus can be made compact in size.
Abstract:
In a color picture recording apparatus, a picture image of an original document is formed on a photosensitive and pressure-sensitive recording medium which may be either a self-coloring type or a transfer type made up of a microcapsule sheet and a developer sheet. According to one aspect of the present invention, in the recording apparatus of the type in which the transfer type recording medium is used, the copy sheets are discharged face-up so as to facilitate an operator's confirmation of the copied picture image. According to another aspect of the invention, the cut developer sheets are stacked in a sheet cassette so that the surface on which the developer material is coated is face-down so that a feeding roller for feeding out the developer sheet does not come into contact therewith. According to still another aspect of the invention, in an apparatus of the type in which a mask member is used for forming a latent image on the recording medium, the mask member and the recording medium are held in intimate contact with each other when exposure is taking place.
