Embodiment Construction

[0024] Reference will now be made in detail to the embodiments of the present general inventive concept illustrated in the drawings, wherein like reference numerals refer to like parts throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.

[0025] 3 and 4 are schematic and perspective views illustrating a scanning unit according to an embodiment of the present general inventive concept. Referring to FIGS. 3 and 4 , a document 40 to be scanned is placed on the plate member 30 . The document 40 is, for example, a sheet of paper or a book. The plate member 30 is, for example, a transparent plate. The first and second carriages 100 and 200 and the imaging body 300 are installed under the plate 30 . The imaging body 300 is, for example, an image sensor for detecting light reflected from the document 40 and converting the light into an electrical signal to read information on the document 40 . The i...

Abstract

A scanning unit includes: first and second carriages, a first wire to make a closed loop supported by a plurality of first pulleys and connected to the first carriage to move the first carriage, a second wire to make an open loop supported by a plurality of second pulleys installed in the second carriage and connected to the first carriage, and a motor to drive the first wire.

Description

technical field [0001] The present general inventive concept relates to a scanning unit usable in a copier, a scanner, or a multifunction device with a scanning function, and more particularly, to a scanning unit having two carriages facing Moves in the same direction and guides the light reflected from the original to the imaging object. Background technique [0002] FIG. 1 is a diagram showing a conventional scanning unit having two carriages. Referring to FIG. 1 , mirror 6 is mounted on a first carriage 1 , and mirrors 7 and 8 are mounted on a second carriage 2 . The light rays L reflected from the document D on the transparent plate 5 are guided through the mirrors 6 , 7 and 8 and projected onto the imaging body 3 . The first and second carriages 1 and 2 move in a direction A to scan a document D. As shown in FIG. FIG. 2 is a view showing a conventional apparatus using a belt 9 to move the first and second carriages 1 and 2 of the conventional scanning unit shown in F...
