摘要:
An integrated image read/write head (A) comprises a long rectangular substrate (4) having a first side edge (4c) and a second side edge (4d) in the direction of width and carrying a plurality of photodetector elements (2), and driver ICs (80) are arranged in rows on its one side (4a). A long case (1) is attached to house the photodetector elements (2) and driver ICs (80) on the side (4a) of the substrate (4) in such a manner that the first edge (4c) of the side of the substrate (4) is exposed along a predetermined width. A source of light (3) is also arranged on the side (4a) and housed in the case (1). A plurality of heating elements (8) are mounted on the exposed part of the side (4a) of the substrate (4).

An image read/write head (A) includes: a substrate (4) having a first widthwise side portion (4c), a second widthwise side portion (4d), and an upper surface carrying a row of light-receiving elements (2) longitudinally of the substrate; an elongate case (1) mounted to the upper surface of the substrate (4) to enclose the light-receiving elements (2); a transparent cover (19) mounted to an upper surface of the case (1) for contact with a document to be fed; a light source (3) disposed in the case for illuminating the document; a lens (5) disposed in the case for causing an image of the document (D) illuminated by the light source (3) to be formed on the light-receiving elements (2); and a row of printing elements (8) carried by the an upper surface of the substrate at an excess portion which is provided by extending the first side portion (4c) beyond a lower edge of the case (1) by a predetermined amount. The transparent cover (19) is inclined such that the cover (19) becomes progressively farther from the substrate as it extends toward the first side portion (4c) of the substrate (4).

摘要:
A multi-mode reproduction machine or copier incorporating a full width read/write bar (50) having at least one linear array (41) of LEDs (42) either for selectively scanning a document original (11) in a read mode or for exposing the copier photoreceptor (22) in a write mode. An array (45) of lens elements is provided for focusing the LED array on both the document original and the photoreceptor, the read/write bar and lens array being combined in a unitary structure selectively movable between read and write positions. In an alternative embodiment the read/write bar and lens array is disposed in a fixed position to permit selective reading of the image developed on the photoreceptor or writing of images onto the photoreceptor.

In an image-recording system with at least one photodetector for each picture element to be recorded, a focusing element is provided in front of the (minimum of one) photodetector and serves to focus one picture element onto each photodetector. A combination with a screen, in particular a colour screen, is also possible, in which case a single surface serves for recording and reproduction.

An optical read device comprises thin-film electroluminescent light sources (12) which illuminate the paper surface, reflecting the light back through co-aligned apertures (18,21) to detector elements (22), both the light sources and detector elements being defined on or supported by a common substrate, eg glass (192). Also disclosed is a multi-function opto-electronic read/write device (162) having a pixellated light source and detector array, which is capable of operating in two distinct modes - read only and write or printhead mode.

A semi-conductor device comprises a plurality of photo-sensor cells (2₁, 2₂...2 n ) for reading image data, drive means (16₁, 16₂...16 n ) for driving printing cells in printing means, and control means (11₁, 11₂...11 n , 12₁, 12₂...12 n , 13₁, 13₂...13 n , 14₁, 14₂...14 n and 15₁, 15₂...15 n ) for controlling the drive means in response to received printing data and for processing output signals from the photo-sensor cells. The photo-sensor cells, the drive means and the control means are formed on a single substrate as integrated circuits.
