Flexible optical fibers for use in viewing devices
First Claim
1. A twisted flexible optical fiber bundle for use in viewing devices comprising a plurality of flexible optical fibers disposed in parallel with one another to define flexible optical fiber gatherings, each of said flexible optical fiber gatherings being twisted by 180°
- to define twisted flexible optical fiber gatherings so that a right side-left side inverted image is formed of an object viewed through a viewing device, said twisted optical fiber gatherings being longitudinally laminated together to define the twisted flexible optical fiber bundle.

Abstract
A twisted flexible optical fiber bundle adapted to be used in viewing devices for transportation vehicles such as automobiles, the twisted fiber bundle being prepared by twisting each of flexible optical fiber gatherings by 180° prior to longitudinally laminating the thus twisted optical fiber gatherings, thereby forming a right side-left side inverted image when used in viewing devices; and viewing devices in which the twisted flexible optical fiber bundle is used as the image transmitting means.

3. A viewing device for observing the right side-left side inverted image of an object which is outside the field of view of an observer, comprising at least one object lens fixed to observe areas outside the field of view of an observer, an image forming unit set up in front of the observer and a flexible optical fiber bundle connected at one end to the at least one object lens and at the other end to the image forming unit, said flexible optical fiber bundle comprising a plurality of flexible optical fibers disposed in parallel with one another to define flexible optical fiber gatherings, each of said flexible optical fiber gatherings being twisted by 180°
- to to define twisted flexible optical fiber gatherings so that a right side-left side inverted image is formed of an object viewed through a viewing device, said twisted optical fiber gatherings being longitudinally laminated together to define the twisted flexible optical fiber bundle, thereby an image received by the object lens is transmitted through the twisted flexible optical fiber bundle to the image forming unit in which the right side-left side inverted image is formed.
