Abstract
A lens unit includes a first lens array including first lenses arranged in at least two lines; a second lens array including second lenses arranged in an arrangement relationship corresponding to the first lens array, the second lenses respectively facing the first lenses, the second lens array being arranged to face the first lens array so that each pair of the first and second lenses has a common optical axis; and a first light blocking member arranged between the first lens array and the second lens array and having first openings each being arranged to face the pair of the first and second lenses in a direction of the optical axis. An interval PXL from an array center position between two adjacent lines to the optical axis and an interval PXS from the array center position to an opening center of the first opening satisfy PXL

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. 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.
