Abstract
Abstract A printing apparatus with an image reading device, having a platen extending along a line of printing, a guide rod extending parallel to the platen, a carriage movable on the guide rod, and a printing head which is mounted on the carriage to effect a printing operation a recording medium on the platen. The image reading device comprises: a pair of support portions which slidably engage the guide rod so as to sandwich the carriage in a direction parallel to the line of printing; a bridging portion connecting the support portions such that the support portions are immovable relative to each other; an image-reading portion supported immovably relative to the support portions and the bridging portion, and having an operative position adjacent to the surface of the recording medium, for reading images on the surface; and a control circuit fixed to the bridging portion, for controlling an image-reading operation of the image-reading portion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
204 words
A printing apparatus with an image reading device, having an elongate platen extending along a line of printing, a guide rod extending parallel to the elongate platen, a carriage in slidable engagement with and movable on the guide rod, and a printing head which is mounted on the carriage to effect a printing operation along said line of printing on a recording medium on the platen as the carriage is moved on the guide rod, said image reading device comprising: a pair of support portions which slidably engage said guide rod and are disposed in a spaced-apart relation from each other so as to sandwich said carriage in a direction parallel to said line of printing, wherein said support portions are immovable relative to said carriage in said direction; a bridging portion which connects said pair of support portions such that the support portions are immovable relative to each other; an image-reading portion supported immovably relative to said support portions and said bridging portion, and having an operative position adjacent to the surface of said recording medium on said platen, for reading images on said surface; and a control circuit fixed to said bridging portion, for controlling an image-reading operation of said image-reading portion.

A printing apparatus with an image reading device, having an elongate platen extending along a line of printing, a guide rod extending parallel to the elongate platen, a carriage in slidable engagement with and movable on the guide rod, and a printing head which is mounted on the carriage to effect a printing operation along said line of printing on a recording medium on the platen as the carriage is moved on the guide rod, said image reading device comprising: a pair of support portions which slidably engage said guide rod and are disposed in a spaced-apart relation from each other so as to sandwich said carriage in a direction parallel to said line of printing, wherein said support portions are immovable relative to said carriage in said direction; a bridging portion which connects said pair of support portions such that the support portions are immovable relative to each other; an image-reading portion supported immovably relative to said support portions and said bridging portion, and having an operative position adjacent to the surface of said recording medium on said platen, for reading images on said surface; and a control circuit fixed to said bridging portion, for controlling an image-reading operation of said image-reading portion.
Claim 3
Dependent Claim
27 words
A printing apparatus with an image reading device according to claim 1, wherein said bridging portion extends below said carriage, to connect said pair of support portions.
Claim 4
Dependent Claim
26 words
A printing apparatus with an image reading device according to claim 1, wherein said control circuit is fixed to a lower surface of said bridging portion.
Claim 5
Dependent Claim
157 words
A printing apparatus with an image reading device according to claim 1, wherein said image reading device further comprises a plurality of light-emitting optical fibers, and a plurality of light-receiving optical fibers, first ends of said light-emitting optical fibers and first ends of said light-receiving optical fibers being fixed adjacent to each other on said image-reading portion, said control circuit including a plurality of light-emitting elements for emitting beams of light which are transmitted through said light-emitting optical fibers toward said surface of the recording medium, and further including at least one light-sensitive element for receiving the beams of light reflected from said surface of the recording medium through said light-receiving optical fibers, second ends of said light-emitting optical fibers opposite to said first ends thereof being positioned opposite to said light-emitting elements, and second ends of said light-receiving optical fibers opposite to said first ends thereof being positioned opposite to said at least one light-sensitive element.
Claim 6
Dependent Claim
63 words
A printing apparatus with an image reading device according to claim 1, wherein said image-reading device further comprises an arm portion which extends from one of said pair of support portions in a direction away from an axis of said guide rod, said image-reading portion being disposed on a distal end of said arm portion remote from said one of the support portions.
Claim 7
Dependent Claim
48 words
A printing apparatus with an image reading device according to claim 1, wherein said image reading device is supported by said guide rod pivotally between said operative position and an inoperative position away from said operative position in a direction away from said surface of the recording medium.
