A printer includes a housing, a shaft connected to an inner surface of the housing at a first end thereof, extending along a first direction to a second end, and by which an ink ribbon is held, a print head connected to the surface at a first end thereof, extending along the direction to a second end, and transferring ink from the ribbon to a sheet, a roller connected to the surface at a first end thereof, extending along the direction to a second end, and conveying the sheet, and a holding plate connected to the second end of the roller and rotatable around a first hinge and by which the second ends of the shaft and the head are held when the plate is rotated about the first hinge to be parallel to the surface. The plate includes a second hinge about which the holding plate is foldable.

According to an embodiment, an image forming apparatus includes a scanner unit, an image forming unit, a frame, a first adjustment mechanism, and a second adjustment mechanism. The scanner unit has an image reading section. The image forming unit forms an image read by the scanner unit on a sheet. The frame includes a first support section and a second support section. The first support section supports the image forming unit. The second support section is positioned below the scanner unit. The first adjustment mechanism steplessly adjusts a distance in an up-down direction between the scanner unit and the second support section. The second adjustment mechanism gradually adjusts the distance in the up-down direction between the scanner unit and the second support section.

Image forming apparatus with an adjustable scanner

An image reading apparatus includes a scanner which has a document table for loading a document on the upper part of a main body, detects optical image information reflected from the document, and reads the document image, a support member for surrounding the main body, a plurality of cushioning members installed between the main body and the support member at the position for supporting the load of the main body for preventing transfer of vibration from the support member to the main body, and at least one adjustable bracket which is mounted on the main body, can adjust the support height of the main body to the support member, and supports the cushioning members.

A system and method for scanning a document having a plurality of pages includes scanning a first page in the document at a first scanning speed, the first scanning speed being one of a color speed and a monochromatic speed, and determining if the first page is color or monochrome based on a result of the scan of the first page. If the first speed is the monochromatic speed and the first page is determined to be color, or if the first speed is the color speed and the first page is determined to be monochrome, then the first page is rescanned at a second scanning speed, the second scanning speed being the other of a color speed and a monochromatic speed.

System and method for scanning or reading documents having both color and monochromatic pages

A scanner unit has first and second carriages under an original table glass. The first carriage has a first frame extending from a front side to a rear side along the original table, that is, in a main scan direction. Two rails for supporting both end portions of the first frame such that the first frame may slide in a sub-scan direction are provided on the front side and rear side of the scanner unit. A cold cathode fluorescent lamp is mounted on the first frame. In order to make a high-voltage-side harness of the cold cathode fluorescent lamp as short as possible, an inverter circuit board, which is a lighting circuit, is disposed as close as possible to a positive electrode of the cold cathode fluorescent lamp. A weight is attached on a side opposite to the inverter circuit board, thereby to stabilize a weight balance of the first frame in the main scan direction.

Scanner unit and carriage therefor

A scanner unit is provided, which can make the amounts of light directed to a read line from the opposite sides of the optic axis plane substantially the same, thereby preventing a shade due to an edge of an attachment portion on a document form occurring. In the scanner unit of the present invention, the carriage mirrorand the second carriageof the optical reading device read a document by scanning read lines LL on the document in the scanning direction (R, F) and using light reflected from the document along an optic axis plane PP which contains the read line and extends in perpendicular relation to a document glass table. An exposure lampand a reflectorforming an illumination device illuminate the read line from both sides of the optic axis plane with the light passing along light path L, Land the light passing along light path L, L, respectively. An light amount adjusting member, e.g., a filter, reduces the amount of light passing along the light path L, Lso that the amounts of illumination light directed from both sides of the optic axis plane are made substantially the same at the read line, thereby preventing a shade when reading an edge of an attachment portion on the document.

Optical reader

An apparatus for conveying a paper along a paper conveying path, the apparatus includes a pair of guide plates for guiding a paper in the paper conveying path, the guide plates being movable between a first position located in the paper conveying path and a second position located out of the paper conveying path and a roller located in the paper conveying path for conveying the paper. The roller is rotated in response to the moving of the guide plates from the first position to the second position so that the paper in the paper conveying path is fed from the guide plates.

A developing device for developing an electrostatic latent image formed on an image carrier includes a roller which carries toner particles to the developing position and a porous foam member of a material such as urethane resin which contacts the roller. The porous foam member comes in contact with either a developing roller or a toner supply roller which supplies toner particles to the developing roller. Toner particles supported in the holes of the porous foam member are charged as the particles rub against the developing roller or toner supply roller, causing the particles to be readily transferred to the roller. The porous foam member causes the amount of toner particles supported on the surface of the developing roller or the toner-supply roller to be sufficient to prevent a reduction in the density of the toner image even directly after a larger amount of toner particles are consumed for developing a solid toner region for example.
