Abstract

Abstract A document reading apparatus has a document placing plate and a transparent flat plate (4) which hold a document therebetween with a surface to be read of the document directed upward, a sensor unit (5) for reading image information of an image on the document surface to be read through the transparent flat plate (4), a drive mechanism (10, 11) for driving the sensor unit (5) in a direction parallel with the flat plate (4), and a position entering unit (7) for indicating an arbitrary position on the document surface to be read by a visible light through the transparent flat plate (4) and for detecting the position in association with a transparent tablet (6). Image reading and position entry can be made with a document held in the apparatus.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 84 words
A document reading apparatus comprising: document holding means (100) for holding a document with a surface to be read; image reading means (5) for reading image information of an image on the surface to be read of the document; and position entering means (7) for entering position information of the image on the surface to be read of the document, wherein said image reading means (5) and said position entering means are disposed at a same side with respect to said document holding means.
Claim 2
Dependent Claim 84 words
A document reading apparatus comprising: document holding means (100) for holding a document with a surface to be read; image reading means (5) for reading image information of an image on the surface to be read of the document; and position entering means (7) for entering position information of the image on the surface to be read of the document, wherein said image reading means (5) and said position entering means are disposed at a same side with respect to said document holding means.
Claim 3
Dependent Claim 75 words
Apparatus as set forth in claim 1, wherein said image reading means (5) includes means (22) for illuminating the document surface, means (13) for photoelectrically converting a reflected light from the document surface to an electric signal, guide means (9a,9b) for supporting said illuminating means and said photoelectrically converting means movably in parallel with the document surface, and drive means (10,11) for driving said illuminating means and said photoelectrically converting means along said guide means.
Claim 4
Dependent Claim 66 words
Apparatus as set forth in claim 1 or 2, wherein said position entering means (7) includes a transparent position detector plate (6), position indicating means (35,36) adapted to indicate an arbitrary position on the document surface, and position detecting means (45,37) adapted to detect a position on said position detector plate (6) corresponding to the position on the document surface indicated by said position indicating means.
Claim 5
Dependent Claim 28 words
Apparatus as set forth in claim 3, wherein said position detector plate (6) is adapted to be parallel with the document surface when the position information is entered.
Claim 6
Dependent Claim 49 words
Apparatus as set forth in claim 3 or 4, wherein said position indicating means (35,36) includes a light emitting element (40) for emitting a visible light, and condensing means (42) for condensing the light from said light emitting element onto the document surface to form a light spot (70).
Claim 7
Dependent Claim 55 words
Apparatus as set forth in claim 3 or 4, wherein said position indicating means includes a light emitting element (40) for emitting a visible light, condensing means (42) for condensing the light from said light emitting element onto the document surface, and a focusing "plate (41) between said light emitting element and said condensing means.
Claim 8
Dependent Claim 28 words
/ 7. Apparatus as set forth in any one of claims 3 to 6, wherein said position detecting means (37) is supported by said position indicating means (35,36).
Claim 9
Dependent Claim 31 words
Apparatus as set forth in any one of the preceding claims, wherein said image reading means (5) is disposed between said document holding means (100) and said position entering means (7).
Claim 10
Dependent Claim 84 words
Apparatus according to any one of the preceding claims, and comprising a first unit (100) for placing thereon the document with a surface to be read; a second unit (200) movable toward and away from said first unit (100) and having a plane defining means (4) for flattening the document surface; and means (8a,8b) for movably connecting said second unit (200) with said first unit (100); said image reading means (5) and said position entering means (7) being provided on said second unit (200).
Claim 11
Dependent Claim 29 words
Apparatus as set forth in claim 9, wherein said position entering means (7) comprises a transparent position detector plate (6) provided on a surface of said second unit (200).
Claim 12
Dependent Claim 28 words
Apparatus as set forth in claim 9 or 10, wherein said plane defining means (4) comprises a transparent plate provided on a surface of said second unit (200).
Claim 13
Dependent Claim 39 words
Apparatus as set forth in claim 9,10 or 11, further comprising document pressing means (31,32,33) provided in said first unit (100) for pressing the document against said plane defining means (4) in a direction perpendicular to the document surface.
Claim 14
Dependent Claim 58 words
Apparatus as set forth in claim 12, wherein said document pressing means comprises a document placing table (26) having thereon a resilient member (27) for supporting thereon the document, and means for urging said document placing table in a direction towards said plane defining means (4) whilst maintaining said table (26) parallel to said plane defining means (4).
Claim 15
Dependent Claim 46 words
Apparatus as set forth in any one of claim 9 to 13 wherein said connecting means comprises a hinge (8a,8b) which is rotatable about an axis parallel to a side surface of said second unit (200) and is stoppable at any position within a rotatable range.
