Abstract
Abstract An original-holding mechanism for an original-support device is disclosed which includes a flexible holding member for covering an original document placed on a transparent plate and a rigid supporting member located outwardly of the original-holding member. One end edge portion of the original-holding member is mounted adjacent to one end edge of the transparent plate. The base portion of the supporting member is mounted for pivotal movement about an axis extending along said one edge of the transparent plate as a center. The free end edge portion of the original-holding member is connected to the free end portion of the supporting member for movement over a predetermined range in a direction perpendicular to said axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
202 words
In an original-holding mechanism for an original-support device in a copying apparatus, said original-holding mechanism including a flexible holding member for covering an original document placed on a transparent plate and a rigid supporting member located outwardly of the flexible holding member with respect to the transparent plate; the improvement comprising first means mounting the flexible holding member with one end edge portion thereof adjacent to one end edge of the transparent plate, second means mounting the base portion of the rigid supporting member for pivotal movement about an axis extending along said one end edge of the transparent plate, a first reinforcing piece extending along and affixed to the free end edge portion of the flexible holding member, a connecting member fixed to the reinforcing piece at an intermediate portion thereof in the direction of said axis and slidably connected to the free end portion of the rigid supporting member for slidable movement over a predetermined range thereon in a direction perpendicular to said axis, whereby the free end edge portion of the flexible holding member is connected to the free end portion of the rigid supporting member and is slidable with respect thereto to permit movement over the predetermined range.
Claim 2
Dependent Claim
202 words
In an original-holding mechanism for an original-support device in a copying apparatus, said original-holding mechanism including a flexible holding member for covering an original document placed on a transparent plate and a rigid supporting member located outwardly of the flexible holding member with respect to the transparent plate; the improvement comprising first means mounting the flexible holding member with one end edge portion thereof adjacent to one end edge of the transparent plate, second means mounting the base portion of the rigid supporting member for pivotal movement about an axis extending along said one end edge of the transparent plate, a first reinforcing piece extending along and affixed to the free end edge portion of the flexible holding member, a connecting member fixed to the reinforcing piece at an intermediate portion thereof in the direction of said axis and slidably connected to the free end portion of the rigid supporting member for slidable movement over a predetermined range thereon in a direction perpendicular to said axis, whereby the free end edge portion of the flexible holding member is connected to the free end portion of the rigid supporting member and is slidable with respect thereto to permit movement over the predetermined range.
Claim 3
Dependent Claim
61 words
In the original-holding mechanism of claim 1, the further improvement wherein said first means comprises a second reinforcing piece extending along said one end edge portion of the flexible holding member and fixed to the outside surface of said one end edge portion, and third means mounting the second reinforcing piece adjacent to said one end edge of the transparent plate.
Claim 4
Dependent Claim
46 words
In the original-holding mechanism of claim 2, the further improvement wherein said third means comprises a projecting portion projecting beyond said one end edge portion of the flexible holding member, and means fixing the projecting portion adjacent to said one end edge of the transparent plate.
Claim 5
Dependent Claim
138 words
In the original-holding mechanism of claim 1, the further improvement wherein said rigid supporting member comprises a metal rod having first and second end portions, each extending from the base portion thereof in a direction perpendicular to said axis and spaced apart in the direction of said axis, third and fourth portions extending respectively from ends of the first and second end portions in directions inclined toward each other, fifth and sixth portions spaced from each other and extending respectively from ends of the third and fourth portions in a direction perpendicular to said axis, seventh and eighth portions extending respectively from ends of the fifth and sixth portions in an upwardly inclined direction normal to the axis, and a ninth portion joining ends of the seventh and eighth portion to permit gripping of said rigid supporting member.
Claim 6
Dependent Claim
28 words
In the original-holding mechanism of claim 4, the further improvement wherein said connecting member is slidably connected to the seventh and eighth portions of the rigid supporting member.
