Abstract
A compact specular reflection type image pickup unit has a light source 11 mounted at a position a specified distance away from the target surface of an original P, and the light source 11 emits an outgoing light ph 11 at an angle .theta. to the normal to the target surface. The emitted light ph 11 passes through a glass plate 12 and is incident on the focal points f of a rod lens array 13 on the target surface of the original P at an incidence angle .theta., and is reflected at a reflection angle .theta. as a reflected light rf11. The reflected light rf11 is converged by the rod lens array 13, received by an image pickup element 14 and converted into electric signals. A board 14a is arranged such that the light-receiving faces of the image-pickup elements are parallel with the target object surface of the original P, and the board 14a is fixed to the bottom wall of a housing 15A. As a consequence, the height of the housing 15A is smaller by L1 than that of the housing 5.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
