Abstract
Abstract An electonic copying machine for making a hard copy of a remote original comprises a housing and an image pick-up unit pivotally mounted on the housing for vertical swinging movement between a raised use position and a lowered non-use position. In the housing, there are a scanner for scanning the remote original with a line of light projected through a transparent window plate, a recording head and image recording paper. In the image pick-up unit, there are a lens for forming a line image of the scanned remote original on the recording paper, a line image sensor for reading the line image formed thereon by the lens to provide line image signals according to which the image recording head records and image on the recording paper, shifting the line image sensor by a predetermined pitch in a direction perpendicular to the longitudinal direction of the line image sensor. When the image pick-up unit is folded down, the transparent window plate is covered by the image pick-up unit and the lens is received in a space formed in a corner of the housing and the electronic copying machine then has the shape of a generally rectangular box.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
150 words
An electronic copying machine for making a hard copy from an original remote therefrom, comprising: a housing comprising a supporting base of the machine; an image pick-up unit pivotally mounted on said housing for vertical swinging movement relative to the housing about a horizontal axis, between a raised operative position and a lowered inoperative position; a line image sensor disposed in said image pick-up unit for sensing a remote original line by line to generate line image signals; shift means in said image pick-up unit for moving said line image sensor in a direction parallel to a said sensed line image; a recording head disposed in said housing for recording an image of said remote original according to said line image signals; and a line illuminating system in said housing for directly projecting a line of light onto said remote original in the longitudinal direction of said line image sensor.
Claim 2
Dependent Claim
150 words
An electronic copying machine for making a hard copy from an original remote therefrom, comprising: a housing comprising a supporting base of the machine; an image pick-up unit pivotally mounted on said housing for vertical swinging movement relative to the housing about a horizontal axis, between a raised operative position and a lowered inoperative position; a line image sensor disposed in said image pick-up unit for sensing a remote original line by line to generate line image signals; shift means in said image pick-up unit for moving said line image sensor in a direction parallel to a said sensed line image; a recording head disposed in said housing for recording an image of said remote original according to said line image signals; and a line illuminating system in said housing for directly projecting a line of light onto said remote original in the longitudinal direction of said line image sensor.
Claim 3
Dependent Claim
28 words
An electronic copying machine as defined in claim 1, wherein said housing has a transparent window plate through which said line of light passes to said remote original.
Claim 4
Dependent Claim
21 words
