Abstract: A facsimile device has optical reader unit, an original transport unit, a printing unit, and a base unit. The optical reader unit comprises a light source for illuminating an original document, and an image reading element for receiving and reading the light reflected from the original document. The original transport unit comprises a feed roller and original guides for transporting the original document to an original reading position of the optical reader unit. The printing unit comprises a printer head and a flexible member which presses the printer head on a recording paper to be copied. The base unit comprises a recording paper holder and a platen. The base unit is provided for supporting each of the optical reader unit, the original transport unit and the printing unit.

Abstract: A facsimile device is composed of three separate units which are connected rotatably with respect to one another. A passageway for recording sheets is formed between the first and second units and can be opened and closed by rotating the second unit with respect to the first unit. Another passageway for an original document is formed between the second and third units and can be opened and closed by rotating the third unit with respect to the second unit. With the device thus structured, a jammed original as well as a jammed recording sheet can be removed quickly from the device.

Abstract: A paper transport system for supplying papers such as manuscripts separately one by one along a paper transport passage through the gap between a paper feed roller and a separation rubber plate pressed by a separation leaf spring against the paper feed roller. When no papers are set, a pair of relatively shorter paper feed leaf springs on either side of the separation plate and leaf spring contacts the paper feed roller upstream of the paper transport passage forward of a contact line between the rubber separation plate and the paper feed roller.

Abstract: An image reading apparatus in which an optical system is formed into a unit to make the entire construction compact and facilitate positioning of each component.The optical unit comprises a block structure provided with mounts for supporting a light source base, a lens and a sensor base, respectively.An array of light emitting elements is arranged as a light source on the light source base, and da CCD image sensor is arranged on the sensor base. An end of the lens is positioned at the document reading zone and the other end of the lens is positioned adjacent the sensor base.

Abstract: A recording head device comprises a roller, a recording head disposed opposite to this roller, a securing member, a frame with a hole, a pin passing through this hole in contact with the securing member, and a supporting means for supporting the recording head, having an elongate hole and being engaged by the pin between the securing member and the frame so that a small relative motion caused, for example, by deformation of the device is allowed between the securing member and the recording head and a uniform pressure can be maintained between the roller and the recording head.

Abstract: An optical reader reads draft picture information by guiding reflection light from the optically scanned draft onto the reader element. The optical reader embodiment is provided with the molded supporting member that integrally secures a plurality of blocks supporting the optical elements including a plurality of reflection mirrors that guide the reflection light onto the reader element, a focus lens that focuses the reflection light projected from these reflection mirrors onto the reader element, and the reader element, respectively. Spring clips are used to secure the reflection mirrors to corresponding blocks of the molded supporting member.

Abstract: A multi-pin-electrode electrostatic recording system includes a recording head having 2048 pin electrodes aligned in a line and 65 pairs of auxiliary electrodes positioned near the pin electrodes. A negative recording pulse is applied to a selected pin electrode when a positive recording pulse is applied to a corresponding pair of auxiliary electrodes to form an electrostatic latent image on a dielectric layer of a recording paper. A compensation negative voltage pulse is applied to the auxiliary electrodes, the compensation negative voltage pulse having a pulsewidth longer than the positive recording pulse and the positive recording pulse being superimposed on the compensation negative voltage pulse. By the compensation negative voltage pulse, the occurrence of the ghost image on the non-selected image point is eliminated.
