Abstract
Abstract An image reader including: a scanning mechanism section for holding an imaging optical unit and a solid-state image pick-up device, and for rotating the imaging optical unit and the solid-state image pick-up device in an arbitrary direction and another direction orthogonal to that arbitrary direction respectively, so that an original image can be picked up with an arbitrary resolution while being segmented into a plurality of pieces; and a control section for driving the scanning mechanism section in accordance with the original image and for synthesizing the segmented image to produce original image data. As a result of this construction, the image reader is down-sized and does not require that the original be placed on the platen glass facedown and at a predetermined position, to dispense with the conventionally required complicated operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
An image reader comprising: imaging optical means whose magnification is variable; a solid-state image pick-up device arranged with a predetermined positional relation with respect to said imaging optical means; a scanning mechanism section for holding said imaging optical means and said solid-state image pick-up device, and for picking up an original image with an arbitrary resolution by segmenting said original image into a plurality of pieces while rotating said imaging optical means and said solid-state image pick-up device in an arbitrary direction and another direction orthogonal to said arbitrary direction respectively; and control means for driving said scanning mechanism section in accordance with said original image and for synthesizing said segmented image picked up by said scanning mechanism section to produce original image data.
Claim 2
Dependent Claim
124 words
An image reader comprising: imaging optical means whose magnification is variable; a solid-state image pick-up device arranged with a predetermined positional relation with respect to said imaging optical means; a scanning mechanism section for holding said imaging optical means and said solid-state image pick-up device, and for picking up an original image with an arbitrary resolution by segmenting said original image into a plurality of pieces while rotating said imaging optical means and said solid-state image pick-up device in an arbitrary direction and another direction orthogonal to said arbitrary direction respectively; and control means for driving said scanning mechanism section in accordance with said original image and for synthesizing said segmented image picked up by said scanning mechanism section to produce original image data.
Claim 3
Dependent Claim
22 words
The image reader of claim 1, further comprising means for outputting the original image data from the control means to a computer.
Claim 4
Dependent Claim
22 words
The image reader of claim 1, further comprising means for detachably mounting said scanning mechanism section to a body of a computer.
Claim 5
Dependent Claim
122 words
An image reader, comprising: a rotatable imaging optical means attached to a frame; a solid-state image pick-up device attached to the frame, the solid-state image pick-up device being rotatable in a direction orthogonal to the rotational direction of the imaging optical means; means for detecting the size of an image original by rotating the solid-state image pick-up device; means for producing a segmentation count for the image original based on the size of the image original; means for simultaneously rotating the imaging optical means and the solid-state image pick-up device to perform a segmented scanning of the image original based on the segmentation count to produce segmented image data; and means for synthesizing the segmented image data to obtain image original data.
Claim 6
Dependent Claim
122 words
An image reader, comprising: a rotatable imaging optical means attached to a frame; a solid-state image pick-up device attached to the frame, the solid-state image pick-up device being rotatable in a direction orthogonal to the rotational direction of the imaging optical means; means for detecting the size of an image original by rotating the solid-state image pick-up device; means for producing a segmentation count for the image original based on the size of the image original; means for simultaneously rotating the imaging optical means and the solid-state image pick-up device to perform a segmented scanning of the image original based on the segmentation count to produce segmented image data; and means for synthesizing the segmented image data to obtain image original data.
