The invention relates to optical systems for creating an illuminating strip on the surface of a material. Said system comprises an illuminating device containing several light sources located at a distance from the surface of the material, the illuminating device with its light-emitting light sources generating the illuminating strip on the surface of the material, which is displaced in relation to said device. The illuminating device comprises a mirror that focuses the light emitted by the light source into the illuminating strip, a diffusion body on the light emission side facing the surface of the material and at least one reflector module. The light sources feed their light into the reflector module and said module, the diffusion body and the mirror are configured as a single component.

The image formation apparatus has a plurality of cooling fans inside the main body of the apparatus and comprises an error detecting function of detecting occurrence of an error such as a sheet jam, and switches between operation and non-operation of the cooling fans or changes a rotation number thereof in operation according to a form of a detected error. Thus, it allows optimization of in-apparatus the temperature in the apparatus control on error occurrence and temperature control of each inside portion of the apparatus on sheet jam occurrence so as to solve various problems relating to in the apparatus temperature status on the error occurrence.

A high speed imaging apparatus for CCD based scanners comprises a housing having separate compartments which complement modular assemblies installed therein. A decoder compartment houses components associated with locating and decoding an image. An optics compartment houses the mirrors and associated optics for reflecting the subject image onto the CCD detector. A lighting compartment includes high intensity lamps and the associated components for illuminating an object to be imaged. The lighting compartment includes a heat management system which removes the heat from the high intensity lamps and prevents heat from migrating to other compartments within the housing.
