Abstract
Abstract A relatively small and lightweight electrophotographic apparatus includes a support plate for receiving originals, whereby the support plate reciprocates laterally between the front and back sides of the housing for the apparatus, wherein the center of gravity of the apparatus is biased away from the dimensional center of the housing or body toward the one of the front and back sides which the original support plate more greatly extends beyond and away from the body during reciprocation for scanning of originals, whereby even when heavy originals are placed on the original support plate, the apparatus does not tilt or incline away from its resting surface, even when the original support plate is in greatest extension beyond the body or housing. A handle, sheet feed cassette, and sheet feed tray are all mounted on or through one end of the housing to prevent the latter two from dropping out during transport, thereby facilitating transport.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
An electrophotographic copying machine which is provided with an original support plate sliding in successive reciprocation along an upper surface of and laterally between and partially beyond front and rear sides of the body thereof, in the extremes of its frontward or rearward movement, respectively, characterized in that the center of gravity of said body is biased from the dimensional center of said body in the sliding direction of said original support plate toward the one of said front or rear sides of said body which said original support plate extends least beyond in its reciprocation, and also mounting on said one side a handle for transporting said machine, a sheet discharge tray and a sheet feed cassette slideably mounted through holes in said one side.
Claim 2
Dependent Claim
126 words
An electrophotographic copying machine which is provided with an original support plate sliding in successive reciprocation along an upper surface of and laterally between and partially beyond front and rear sides of the body thereof, in the extremes of its frontward or rearward movement, respectively, characterized in that the center of gravity of said body is biased from the dimensional center of said body in the sliding direction of said original support plate toward the one of said front or rear sides of said body which said original support plate extends least beyond in its reciprocation, and also mounting on said one side a handle for transporting said machine, a sheet discharge tray and a sheet feed cassette slideably mounted through holes in said one side.
Claim 3
Dependent Claim
24 words
An electrostatographic apparatus as set forth in claim 1, wherein cushion members are mounted to the side wall counter to the handle mounted side.
Claim 4
Dependent Claim
19 words
An electrostatographic apparatus as set forth in claim 2, wherein said cushion members are belt-like shaped and extend vertically.
Claim 5
Dependent Claim
20 words
