Method of and apparatus for thin plate assembly, and computer product

The thin plate assembly apparatus for inserting a thin plate including a light guide body, into an opening of a U-shaped member, a width thereof is narrower than a thickness of the thin plate, said thin plate assembly apparatus comprising:

• a fixing member for fixing the U-shaped member;
• and
• an edged member having separated two forward ends,
• wherein the fixing member for fixing the U-shaped member and the edged member are moved relatively so that the separated two forward ends are inserted into the opening of the U-shaped member, and a gap between the inserted two forward ends of the edged member is widened so that the width of the opening is expanded, and the thin plate is inserted into the opening with the widened width, and after that the fixing member for fixing the U-shaped member and the edged member are moved relatively so that the edged member is drawn from the opening.

A computer program containing instructions which when executed on a computer causes the computer to insert a thin plate including a light guide body, into an opening of a U-shaped member, a width thereof is narrower than a thickness of the thin plate, the computer program realizing the steps of:

• inserting an edged member having separated two forward ends into the opening of the U-shaped member;
• widening a gap between the two forward ends of the edged member inserted at the edged member inserting step so as to expand the width of the opening;
• inserting the thin plate into the opening, the width thereof is expanded at the expanding step;
• and
• drawing the edged member from the opening after the thin plate is inserted into the opening at the thin plate inserting step.
