<p>PROBLEM TO BE SOLVED: To prevent the occurrence of the skew of a document by a method wherein a protrusion formed on the lower end of one side of paper width regulating plate is energized against the rise surface of one stepped part formed on a document placing table, and the lower end of the other end part of the width regulating plate and the outside part of a rack plate are energized on the rise surface of the other stepped part formed as a reference surface. SOLUTION: By energizing a protrusion part 61, formed on the lower end of one side of a paper width regulating plate 6, on one stepped part 71 of a document placing table 2, the lower end of the other side of the paper width regulating plate 6 and the other side edge of a rack plate 5 are brought into slide contact with and energization on the rise surface of the other stepped part 72 forming a reference surface. Thus, a load is stably exerted on the whole of cursors 1 and 1 and the two paper width regulating plates 6 and 6 are always held in parallel to each other. Further, since hook parts 63 and 63 protruded from the lower part of the paper width regulating plate 6 are fitted in a pull-out prevention state and brought into slide contact with a guide groove 8 formed in the document placing table 2, even when the cursor 1 is moved, the cursor is prevented from dislocation from the document placing table 2 and stably held.</p> |
