Title: Image reader
Inventor: HONDA TAKASHI
IPC: H04N1/193
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To provide an output of a required original image only by detecting a prescribed pattern formed by longitudinal edges and deciding a read area based on the detected pattern to clearly discriminate an original side face part from an index, a black frame pattern and a black background or the like thereby accurately detecting an original front part. SOLUTION: At first, a longitudinal edge is detected and when the length of the longitudinal edge is a prescribed length or over, the subscanning position of the longitudinal edge is stored in a memory as a border object. Then a pattern of an original is detected and when it is detected, the longitudinal edge of the border object toward the center of the original in the detected pattern is decided to be a border in the subscanning direction between an original front part and an original side part. On the other hand, when no pattern is detected, an original upper side edge change amount is detected and the position of the change point is decided to be a border in the subscanning direction on the surface of the original.  Then an area taking upper and lower side edges to be a border in the main scanning direction at the detection of the original size is selected to be an image read area for main scanning.

Dimensions 1 between the internal surfaces against the tip of the protrusion part 5a are made smaller than the diameter of the double end stud and enough to enter into the double end stud with the deformation of the protrusion part 5a. Therefore, the positioning ring 5 inserted into the double end stud can be changed in the inserting position by applying a force but it will not move without the force applied even when the double end stud is inclined in all possible directions. In the extreme case where the piping is vertical, the positioning ring 5 will not move after it is inserted and positioned once.
