Optical fiber positioning element at optical fiber bundling part in optical fiber type display and method of manufacture and optical fiber type display

In a method of producing an optical fiber positioning element (8) of an optical fiber converging portion (3) for converging a large number of optical fibers (5) led to a screen panel (4) for image display in an optical fiber display system,

• an optical fiber converging unit producing method comprising the steps of:
• providing a belt-shaped body (9);
• and
• forming a plurality of optical fiber supports (10) integrally with said belt-shaped body (9) on upper and lower sides of said belt-shaped body at a predetermined pitch in a longitudinal direction of said belt-shaped body.

An optical fiber converging portion (3) for use in an optical fiber display system to converge a large number of optical fibers (5) led to a screen panel (4) for image display, said optical fiber converging portion (3) comprising:

• a plurality of tiers of optical fiber positioning elements (8);
• and
• a plurality of tiers of optical fibers (5), each tier having a plurality of columns of optical fibers (5);
• said tiers of optical fiber positioning elements (8) and said tiers of optical fibers (5) being alternately stacked;
• wherein said optical fiber positioning elements (8) each comprise a belt-shaped body (9) and a plurality of optical fiber supports (10) provided on upper and lower sides of said belt-shaped body (9) at a predetermined pitch in a longitudinal direction of said belt-shaped body, and
• wherein said plurality of columns of optical fibers (5) in each tier are placed in engagement with optical fiber accommodating recesses (10e) of a plurality of optical fiber supports (10) on the upper and lower sides of said belt-shaped body (9).
