PURPOSE:To make the quantity of an optical beam from a light emission end constant by adding a supporting device which moves an optical fiber consisting of a covering material and a core material while generating only torsion. CONSTITUTION:An optical fiber F used for image scanning and recording is supported pivotally in a rocking free state on the end surface 27 of an angle 26 fixed to a device frame at its one end. The angle 26 is provided with a bracket 28, and the fiber F is supported along the 1st oscillatory lever 23 supported on the bracket 28. On the L-shaped inflection surface side of the 1st lever 23, the 2nd hooked oscillatory lever 31 is fitted to support the fiber F aside. A recording head 14 is fitted at the hooked inflection part of the 2nd lever 31 and is connected to the fiber F. Consequently, the fiber F has only torsion according to the movement of the head 14, so an optical beam emitted from the fiber F never attenuates to obtain the constant quantity of light. |
